Water pump for a trimmer for grass with your own hands. Gear water machine

Homemade trimmer for grass: 4 manufacturing options

All owners of personal plots are faced with the problem of mowing grass, which grows literally before our eyes, and during the season it is required to ennoble their site several times. The usual manual spit has been replaced by benzotrimers and electrimmers for a long time. But the price of them does not decrease and is quite noticeable for many owners of cottages and private houses. People’s craftsmen still found a way out of this situation and learned to make trimmers for grass with their own hands literally from improvised means, using benzo- and power tools not intended for these purposes.

Most often, a homemade electric trimmer for grass is made on the basis of a conventional corner grinding grinder, which is available to every home master. This tool is almost perfect for remaking into a trimmer for grass. It has a larger power than store machines and more than a minute. In addition, the standard nut used in the corner grinding for fixing the disks already has holes through which it is easy to insert a fishing line for a trimmer (cord).

So, there are many options from which to make a bar (holding). The simplest is the longer a wooden holder than for a shovel. To the end of it, an angular grinder is attached at the right angle with a conventional tape. The fishing line for the trimmer is inserted into 2 holes of the nut, after which it is twisted. Thus, in a few minutes you get a trimmer for grass, which can be mowed without problems.

For the safety of the operation of a home.made apparatus, you can improve it by making a protective casing (how to do this, will be considered later).

For advanced masters with a welding machine, you can advise a more advanced design to fix the angular grinder and protective casing. It is made from an aluminum tube (serves as a holder) and a metal square profile. Looking at the picture below, you can understand the principle of manufacturing the holder.

The corner grinder is fixed on the holder with bolts inserted into the holes that are designed to attach the handle to the device.

The following photo shows how this design looks below.

Next, the “native” casing of the corner grinder is removed, and instead of the disk, either a fishing line for a trimmer or a metal disk knife is installed.

By the way, you can fasten the holes for fastening the handle (bar) itself, when you want to make a simple trimmer for grass, which is easily assembled and is also easily versed if you need to use the corner grinding for its intended purpose.

To make it more convenient to hold a trimmer for grass in his hands during work, and it did not rotate around the axis of the bar, you can attach a side hand made of a bent pipe to it.

From the vacuum cleaner

The trimmer for grass from the engine from the vacuum cleaner is made according to the same principle as from the corner grinder. The motor must be fixed on the rod, and either knives or a plastic or metal disk in which the fishing line for the trimmer is fixed on the engine shaft. On top of the cutting tool is closed with a protective casing.

So that the dust and small particles of mowed grass do not fall into the engine removed from the vacuum cleaner, it can also be hidden in a plastic casing made of a sewer pipe, as shown in the next photo.

Since the engine in the vacuum cleaner is high.cost, it needs to provide cooling. Therefore, it is recommended to insert a homemade disk with cut and curved blades under the washer, into which the fishing line is inserted, so that it plays the role of a fan that creates a vacuum. It is required so that the air is sucked through the hose from above and cool the motor.

In order to facilitate the load on the hands of the mowing operator, the unit can be installed on the site with wheels. In this case, something similar to the lawnical mower will be obtained.

To fix the fishing line, you can also use either a pulley with a suitable landing hole, or a plastic wheel from a cart.

Wave pump

This design works due to the energy of the waves and is able to pump water from the nearest reservoir.

The main working part of the pump is a hollow cylinder in the form of an accordion. Contracting and stretching, the accordion changes its inner volume. One end of the corrugated pipe is connected to a log located in the water, and the other to the holder on the pile, which is driven into the bottom. On both sides, the accordion has valves installed in the bushings. When the waves raid, the log begins to rise and sink, thereby passing the oscillatory movements to the corrugation, squeezing and unclenching it. If water is poured into it, then the valves will begin to work, and the pump will pump water.

If a corrugated pipe is used with a diameter of 50-60 mm, then the log should be weighing 60-80 kg. So that the log does not break the lift when high waves occur, the limiter should be attached to the pile. A bolt is passed through it and fixed in a log. The bolt head should be under the overhead plate, so that the log will rotate freely in different directions and will not break pile when an undesirable torque occurs.

Important! If there are problems with the search for a corrugated pipe, then there is a design of a wave pump that works without it. Instead of corrugation, rubber ring diaphragms are used, sequentially connected to a single package.

water, pump, trimmer, grass

Ring diaphragms are pulled out of metal rings along the edges, inside and outside. The internal rings are made and metal and make holes in them. A cord is attached between the rings, which will limit the excessive stretching of the pump. Also valves are installed in the upper and lower part of the pump.

When the log is moving up, the bag of membranes is stretched, the lower valve opens, and the pump begins to be filled with water. Когда бревно опускается, пакет сжимается, нижний клапан закрывается, а верхний – открывается. Through it water is squeezed out.

Pump “stove

To assemble a pump working on fire thrust, you can use a metal barrel of 200 liters.

This design is assembled as follows.

  • Build a simple stove from bricks. If desired, it can be provided with grates.
  • In the lower part of the barrel, it is necessary to fix the output crane.
  • Pour several liters of water through the hole in the lid of the barrel. The tap must be closed.
  • Next, tightly fix the rubber hose into the holes of the upper cover. It is very important that air does not suck around the hose.
  • At the other end of the hose, install the mesh filter.
  • Lower the filter hose to the reservoir.
  • Light the firewood under the barrel (the tap should be closed). As the barrel is heated, the air in it will begin to expand and go down the hose in the reservoir.
  • When the air stops leaving the barrel, extinguish the fire. When the barrel is cooled, a vacuum forms in it, and the water will begin to be sucked into it from the reservoir.

Principle of operation

The principle of operation of the piston unit is based on sucking fluid into the cylinder. The movement of the piston pushes air out of the cavity and creates the conditions for moving water. The inlet valve is located inside the case. The output valve is placed on the piston itself. To simplify the functioning of the unit between the modules, a spring is installed that attracts the piston to the base of the cylinder body. “Motor” in this device is the muscular force.

We watch the video, the principle of operation of the unit, and what you need to know before launch:

The principle of operation of the motorcycle is based on the action of centrifugal force forming internal pressure in the cylinder cavity. The unit works on the internal combustion engine. The fuel for the motor is gasoline. The unit on gasoline has a low power resource, but it differs in noiselessness.

What kind of pump to make?

The question of the type of water supply apparatus will depend on the depth of the groundwater

  • If the level of water surfaces does not exceed 10 meters, you should make a shallow water pump.
  • When the groundwater occurs below 10 meters mark, a deep pump is required.

What is the difference between these pumps? In design they are the same. The difference is in the length of the rod, which at the deep unit differs in an increased length.

Design #3. A manual pump with lateral surge

The previous design has one, but a significant drawback. Pouring moves along with a rod. This design is not much more complicated, but much more convenient.

The sleeve must be improved. Add the PVC d tee of. 50mm with a divert of 35 degrees. The tee must be inserted into the upper part of the sleeve. In the rod, near the piston, we drill several holes of large diameter, the main thing is not to overdo it and do not break the stiffness of the entire structure.

The piston moves up pushes the liquid into the output pipe. The upper cover serves as a support for the piston thrust

Now the water will begin to pour into the space between the rod and the sleeve. When the piston moves up, the water will begin to flow into the excess.

Structure #4. piston well pump

This pump design is suitable for wells no more than 8 meters. The principle of operation is based on a permit created by the piston inside the cylinder. Useful homemade can become an excellent alternative to the pumping equipment of factory production, will help solve the problems of water production for servicing a summer cottage.

In such pumps, the upper cover is either absent or has a slit.like hole, since the stem is rigidly connected to the handle

The performance of the pump directly depends on the tightness of the entire structure.

How NOT to mow a hillside 1st day with the new mower

A detailed description of the process of manufacturing a piston pump for use in a summer cottage you will find in one of the popular articles of our site.

Step #1: Assembly sleeve device

For the manufacture of the pump sleeve, it is necessary to pay attention to the inner surface, it should be even and smooth. A good option could be a sleeve from a truck engine.

Below to the sleeve, you need to weld a steel bottom in the diameter of the head of the well. In the center of the bottom, either a petal valve or a factory.

For the top of the sleeve, the lid is made, although this detail is more aesthetic, you can do without it. It is necessary to pay attention to the fact that the hole for the rod of the piston is made sloppy.

Step #2: The construction of the pump piston

For the piston, you need to take 2 metal disks. Between them, lay not very thick rubber 1cm, a little larger diameter than the discs. Next, we pull the discs with bolts.

As a result, the rubber disk will light up and the metal sandwich and rubber should be obtained. The point is to create a rubber rim along the edge of the piston, which will form the necessary sealing piston gilge.

It remains to install the valve and weld the ear for the rod.

Step #3. Making a petal valve made of rubber

The petal valve consists of a rubber disk of not a very large thickness. The size of the disk should be larger. The hole is drilled in terms of rubber. Through this hole and a clamping washer, the rubber disk is attached on top of the intake holes.

When sucking, the edges of the rubber are lifted, and the water will begin to act. With the reverse course, the clamping pressure is created: the rubber reliably blocks the inlet holes.

Step #4: final assembly and installation

It is advisable on the headline of the well and cut the thread in the bottom of the pump sleeve. The thread will easily remove the pump for maintenance and make the installation airtight.

Set the top cover and fasten the handle to the rod. For comfortable work, the end of the handle can be wrapped with electrical tape or rope, laying the turn to the turn.

If the pump does not pump water, it is necessary to eliminate all the leaks, including in conjunction with the head of the well

The restriction on the depth of the well is associated with the theoretical impossibility of creating a discharge of more than 1 atmosphere. If the well is deeper, you will have to modify the pump to the deep.

Option of a compressor pump (Airlift. Erlift)

If the farm already has a compressor, do not rush to purchase an additional pump. You can collect a simple water lift in literally two pipes.

The first pipe serves to supply water. For household needs, Ø 30 mm will be enough. The second is needed to supply air from the compressor. Diameter 10–20 mm.

The efficiency of the pump Erlift directly depends on the power of the compressor, the depth of immersion and the height of the feed. It cannot exceed 70% due to the design features. The efficiency will be equal to the depth of immersion, divided by the sum of the depth of immersion and the height of the rise (all the way of water). In most cases, the optimal power of the compressor is exposed to experimentally.

A visual video of the pump from the compressor:

Water supply since ancient times was the number one task for the survival of entire cities. Today, the savings of energy and natural resources come to the fore. they are becoming less and less, and they become more expensive. Therefore, partial return to the initial technologies without electricity and gasoline is a natural phenomenon. Perhaps in the future this will become the key to a healthy and harmonious life on our planet.

Buscores-highs from the lawn mower-the advantages of the tool

Very often summer residents are faced with the need to cut trees. Using a trimmer for grass and a bitch’s nozzle, you will not need to use a stepladder or climb a tree. Having fixed the device on the rod of the tool, you can cut the branches located at a height of up to 3-4 meters (depending on the length of the bar and the presence of the extension cord).


water, pump, trimmer, grass

The nozzle is also called a high.speed, which is associated with its main purpose. pruning of highly growing branches. The device is a chain tire, like on a chainsaw. The design provides a tank for oil designed to lubricate the circuit. The nozzle is attached to the rod of motorcycles, after which the tool is immediately ready for work.

When choosing a device for a trimmer for grass, you should buy models of a similar tool of the manufacturer, which will eliminate the likelihood of the impossibility of combining devices. When choosing such a device, special attention is paid to the diameter of the bar and the number of drive shaft slots.

When operating the device, it is very important to observe safety precautions. Run the engine with the installed nozzle directly next to the tree, which is planned to be cut. You can order a device for motorcycles on the popular website Aliexpress.

It is interesting! The weight of the equipment is up to 2 kg, and the length of the canvas is 10-15 cm.

The lack of the device is manifested when operating. To cut down thin branches, it is necessary to maintain them, otherwise the vibrations are not an even cut.

Homemade protective casing

If a homemade mower is made by you, then you will definitely need a protective casing. He will protect your eyes, body and legs from injury with small pebbles and fragments of knives if they break.

A trimmer for grass can be made from a sheet of aluminum or thin tin.

    At first, in the corner of the square of the metal it is necessary to drill the hole of the desired diameter (depending on the type of drive of your unit) using the crown.

In this way, you can make and install a protective casing and on a trimmer purchased in a store if the shield has split for some reason. The shields in the factory devices are made of plastic and often break if you unsuccessfully hit the head of the trimmer for grass on the ground for lengthening the fishing line.

Varieties of water.made water pumps

It’s not at all the design is reasonable to assemble independently at home due to the high complexity of the unit. On the contrary, many home.made water pumping devices have been invented, which is really possible to make on their own, while they are better suited for the production of physical experiments and are not entirely practical in the conditions of reality.

These can be considered: wave devices operating on the energy of the surface of the water, units functioning from the energy of the sun, “American” pumps pumping liquid from the stream of fast river, design using a bicycle and other similar.

Manual “rocking”, which are made independently of metal and plastic. Description of several such designs. in a separate article.

The presence of an electric motor with a capacity of 200 W or more allows you to make a fecal, mud or drainage unit for pumping dirty water, that is, from a closely located reservoir, or pumping sewage.

A water pump from a car or a pump from a washing machine in the hands of a home.made car turns into an unit for a summer cottage or waterfall. I propose to consider photos and drawings of real home.made structures for pumping water using an electric drive.

Homemade pumping electric pump for pumping water

Still, pumping water using electricity is noticeably more pleasant than to do it manually. This decision is encouraged by the presence of electricity on the site, as well as a suitable electric motor.

Perhaps you will like a small electric pump pump for supplying water from a closely located reservoir. Such a device is also suitable for the construction of a waterfall or a small fountain on the site.

At the same time, to demonstrate the design of the structure, a drill is used, which should be replaced with an engine with a capacity of 100-1000 watts, since the electric drill over the long-term operation will overheat and fail.

Production technology is based on the use of the following elements:

  • PVC-windows and polymer pipes for sewer networks;
  • 2 bicycle wheels of different diameters;
  • small gear;
  • several ready.made piston structures;
  • nylon fiber rope;
  • rod for fastening.

Water pump using a bicycle wheel.

The sleeve made of a plastic sewer pipe is immersed in the source. The divert designed for water drainage is mounted on top. Small satellite made of smaller diameter rim is installed from below. The larger bicycle wheel is fixed in the upper part of the structure.

The pistons are evenly distributed along the entire length of the nylon twine, fixed on the cable. To ensure normal operating conditions, it is necessary to pass through the sleeve of a homemade pump unit. The rope plays the role of the link between the pulley and the bicycle wheel.

When the gear rotates, the water is captured with pistons fixed on the twine. The device lifts the liquid up, allowing the water flow to be sent to the discharge. To facilitate the use of such a pump, it is recommended to install a bicycle drive in the system.

What to do if the pump accidentally broke, and the child wants to play the ball that needs to be inflated. Go to the store for a new pump, you say, and we will offer to make a simple pump from two plastic bottles. How to do this, you can find out in the video from the author of the idea.

So, we need:. two plastic bottles. a hose from the pump;. wide adhesive tape;. lighter;. electric screwdriver;.drill with a diameter of 3-4 mm.

Note that plastic bottles should be of different diameters. A large bottle should have a larger diameter, and a small bottle. a smaller diameter so that the second is tightly entered in the first.

First of all, in the bottoms of plastic bottles, you need to drill holes.

Next, in the bottle in the diameter, we cut the upper part with a more diameter.

After that, a small bottle should tightly enter the large, but this density is not enough to pump the ball.

To do this, take the tape and wound on a small bottle, thereby getting something like a sealing ring. According to the author, he tried to use elastic bands from bills, but they constantly slipped.

If the bottle after that is very tight, you can lubricate the hand.shaped hand cream with a ring.

We take the lighter and heat the hole made on the bottom of the large bottle before installing the hose from the pump. Thereby the plastic heats up and the thread will be obtained.

The simplest pump from plastic bottles is ready. Let’s move on to testing. To do this, insert the needle into the ball and try to pull the small bottle on ourselves. Note that this cannot be done in any way, since there is a valve in the hose. But then a hole that we drilled in the bottom of. This hole will help remove the vacuum. To do this, when pulling the piston or small bottle, you need to slightly open the lid.

water, pump, trimmer, grass

After the piston is pushed, we close the lid so that the air does not go out and press, watching how the ball is pumped up.

Finally, we note that the author of the idea and we offer you exclusively a prototype, which, of course, cannot be used to pump up car tires or other difficult works. This is just an idea that you, if you wish, can modernize and improve.

There are situations when urgently and in rather large volumes, you need to urgently get rid of the water spilled onto the floor and we are before the question: how to pump water without a pump? One interesting method of pumping water using the law of communicating vessels is described in the video lesson of well.known leading TV shows “Avil Handles”. The authors will offer a working model of a simple manual water pump from a bottle.

Andrey Bakhmetyev offers a manual pump pump device. The main node of the pump is a valve, which is easily made from the neck of a plastic bottle.

We take the cork, remove the gasket from it, which is inside.

In the cork, make a hole with a diameter of approximately 8 mm.

Gently cut the gasket along the edge, leaving a small ledge-shift.

Put the finished part from the gasket in the cork and twist the cut neck, pressing the gasket petal, and leaving the rest of the gasket mobile. The result is a valve.

The valve works like a nipl, releasing air or water only one way.

In the manufactured valve, insert a simple plastic tube, for example, a knob from a mop is suitable.

To increase the surface of the capture of water from the opposite end of the pipe, we put another element of a plastic bottle, which is a neck with a part of a bottle cut to the desired shape.

To control the direction of water flow, you need to attach a flexible hose to the pump.

There is an alternative way to make a pump from a bottle

Love to drink fresh and tasty water? The quality of the water that you drink is very affected by human health and health. Due to the large number of toxins and harmful additives, a high probability of trying poor-quality and even dangerous fluid.

Even if you have installed filters or boil water yourself, it is not always suitable for the office. To protect yourself and others, in addition to high.quality water, the right bottles and pumps should be used. Such tanks should be transparent, and pumps with possible cleaning or possible installation of additional filters.
