How to choose an earthmoving hammer

How to choose an earthmoving hammer. Assortment of goods

In the catalog of equipment are a variety of models, different from each other capacity, auger diameter, duration of torque Why do we need all of these characteristics? How not to get confused when choosing a gasoline drill? It is worth reading this article. and then everything falls into place.

This technique is needed in the economy. Without it one cannot do without it when installing a fence, drilling a well or fishing. it helps to make holes in the ground or in the ice. Depending on the purpose of power drills are divided into two categories.

• For construction work. To make holes in the ground for installing fence posts or blocks for the foundation you can use drills with a drilling diameter of 20 cm and more. If the construction is planned to conduct on clay soil, it is worth thinking about buying a power drill with a high volume and power engine. because only with it the equipment will be able to cope with the difficult task and not to break down before time. For such a case the models with engine more than 30 cc are suitable. Hitachi DA200E(S), Patriot Garden PT AE50, Kalibr BS-1500 and others.
• For fishing. Many people mistakenly think that it is possible to use a gas drill with the same auger for drilling a hole in the ground and in the ice. It is not so. For fishing activities, you need equipment that is equipped with special cutters with a bent surface. Their difference from flat blades is that these parts are able to immediately “grab” a slippery surface and start digging out the material. Motorized drills equipped with such blades, Hitachi DA 300 E, Husqvarna 326AI25 9651863-01.

For work in the winter time, regardless of where the gasoline auger is used. at construction sites or in the household. there is a special category of equipment. It is characterized by high engine torque (above 330 Nm), which makes it easier to make a hole in the frozen ground. For such cases, the EUNO EA-410 and Efco TR 1551 power hammers are optimally suited.

Having determined the tasks to be performed by the technique, it is necessary to consider its technical characteristics. They can help you choose the right engine for your application. What is necessary to pay attention to.

important parameters

First, you need to consider the diameter of the hole to be made in the ground. If it is a large hole with a diameter of 250 mm, it would be impractical to buy a gasoline drill with a cutter diameter of only 200 mm. In this case we would need to manually enlarge the hole, it would be uneven, and so on. In order to avoid problems, it is worth providing for this point.

Second, the drilling depth has to be taken into account. The products presented on our site are optimally suited for drilling wells of 0.6-2 m in depth. This is enough to make a good hole in the ice or a hole for the fence post. In case it is necessary to drill to a depth greater than the specified parameters, it is worth thinking about the purchase of a whole drilling rig. But it is very difficult to operate such equipment, and its cost is high.

Thirdly, as mentioned earlier, it is necessary to provide for the condition of the soil in which you need to make holes. For the frozen clay layer a powerful gasoline drill with a large engine capacity is suitable, for sandstone it is a compact lightweight technique with a small number of revolutions.

Having considered the selection criteria, we can proceed directly to the most important thing. browsing the catalog and ordering. What manufacturers offer at the moment?

What criteria do they pay attention to when choosing?

Motorized drills are used to work on light soils as well as on heavy soils up to the 4th category of complexity. They are used in industry and in the home. In order that such a purchase does not become useless in the end, pay special attention to the selection, taking into account further use.

• engine displacement;
• screw head size;
• the maximum power;
• availability of a safety lock;
• fuel;
• weight;
• removable attachments.

Motor capacity

When choosing the engine displacement of the power drill, consider that it is the engine that determines the speed of the auger that directly drills the soil. The operating size of the engine depends on the type of ground on which the equipment is used.

For example, to drill a hole in sandy soil, the engine volume is sufficient up to 35 cu.m. м. at the same time when working on black earth the engine displacement should be at least 40 cc. м. When processing frozen ground, an engine displacement of about 200 cc is needed. м.

Engine type

Gasoline engines are much more efficient than electric motors, they can withstand higher loads, and they are connected to gears through the usual centrifugal clutch, which slips in the moment of overload. In the process of drilling, the tool is heavily loaded. Because of this, the auger is braked considerably during rotation, which means that the engine speed is also reduced.

The electric motor and gearbox are connected by a special coupling, which ensures a rigid connection without the possibility of slippage. At this point, because of the heavy load and drop in engine speeds, it can simply burn out from constant work. So if you plan to use the power hoe for a long time or on heavy soils, it is worth to give preference to the device with a gasoline engine type.

Power

This parameter has a significant impact on the price and weight of the power drill, as its performance depends on the speed and productivity of the work.

Choosing a light motobuyer, it is unlikely that you will meet a power higher than 3 liters. с. However, in a hard soil light MotoBUER normally can not work, so here you need a professional mechanism operated by two operators. Heavy power drills produce a capacity above 3.5 liters. с.

Auger head size

For work in the garden or vegetable garden, it is better to take a power drill with low power, but the size of the auger should be about 2 meters. If the hole is still larger than the auger, you can also use a special extension. Household use with an auger head with a diameter of 20-25 cm.

In some models there are several types of augers, while other models are presented without them, so you have to buy them separately if necessary. Proper auger size for home and construction work is about 0.7-1 m.

Existence of a safety lock

The safety lock on the rotary hammer is a must to keep you safe while working with the machine. If you hit a rock or a tree root while drilling, the safety device stops the machine.

Fuel

Use only high-quality fuel for a machine and watch condition of blades on auger head. a combination of these factors prevents premature wear of coupling and gearbox.

As a fuel, a substance that includes gasoline and oil (50:1) has proven to be excellent. You need a 25:1 ratio for running-in. That is why when buying the machine it is necessary to find out if the oil tank of the power drill has to be filled.

The weight and dimensions of the power drill depend on the degree of pressure and the use of the power of the drill at work. The power hammers must be able to withstand drilling in winter and summer. At the same time the person working with this equipment must not feel heavy to operate it, so choose the technique according to your physical capabilities:

• Motorized drills weighing from 8 kilograms are designed to perform various works with soil, drilling clay, pressed soil, hard soil and frozen ground, soft shale and other types.
• Power drills with a weight of 10 kilograms are designed for drilling holes in the ground and in ice.
• And power drills weighing 11 kilograms or more are used when planting young trees or renovating fence holes and other construction work.

Removable nozzles

It is recommended to buy a power auger with interchangeable nozzles. Their cost is slightly higher than the cost of power drills without removable attachments, but such tools are much more convenient to use, have less weight and size, which allows you to use the device even alone without help.

In the presence of a removable auger increases the capabilities of the device for excavation work. high-quality and deep holes in the ground are formed due to the fact that you can choose the nozzle that suits best for a particular work. The blades in the respective augers cut small stones and discard large stones, thus avoiding injury to the people working with the power auger.

An overview of the best models

We present the rating of the best power drills for excavation work:

ADA instruments Ground Drill 14 Reverse. Engine power of 8 hp. This is an efficient and powerful power drill with a high reliability rating. It is equipped with a gasoline four-stroke motor and designed for two operators, so it comes with 4 handles. So that the equipment does not get stuck in the ground, the manufacturer has invented the reverse function. Diameter of the hole in the ground is 600 mm.

Varieties of power drills

Distinguish between professional models and gasoline drills for home use. The first type of equipment is more powerful and productive, characterized by the possibility of frequent use with high loads. Domestic samples are oriented to infrequent use for simple manipulations on the site.

The equipment can be manual and wheeled type. The manual type tool is more affordable, provides quality and efficiency sufficient for the average dacha owner. They can be handled by one person, if the drilling depth does not exceed 250 mm.

The second type of tool is equipped with a more powerful and heavy engine. Built-in wheels are used to move around the site. This is an expensive professional machine with a drilling depth of 500 mm or more.

• single-frame, when the engine together with the gearbox is a single unit within a single design;
• Modular. “engine” and gearbox are separated on different carts.

Depending on how they rotate, gasoline-powered drilling machines are differentiated as follows. Hydraulic tools are more reliable in contrast to mechanical devices. They redistribute the load evenly. Parts are therefore less subject to wear and tear, and the tool is preferable for higher workloads.

All the variety of tools can be seen in the picture of the power drill. The models can also differ in the type of gearbox, which is also important to consider when choosing a tool.

How to choose the right tool

In order for the work with a power drill to be effective and bring pleasure, it is necessary to choose the right kind of the tool correctly. When buying, you need to pay attention to several important parameters:

Power. This indicator affects the performance of the equipment, the speed and quality of the work performed. But a more powerful tool will cost more. You can check this parameter on the label or in the instructions.

But for productive work, it is recommended to buy models more than 2.5 liters.с. Here it is important to assess the characteristics of the soil on the site. for more dense soils will require powerful equipment.

auger size. They are determined by the diameter and depth of holes you plan to drill. Some models may only include one head, while others will require additional equipment. Average auger length is 700-1000 mm. Diameter size of the cutter is determined individually.

Engine volume is selected based on the required auger rotation speed in the soil and soil characteristics. If the soil is loose, such as sandy type, then the tool for 2 liters is suitable.с. With the volume of the “engine” not more than 35 cc. м. But the black earth will require at least 3 liters.с. with a volume of 40 cc or more. м.

Features of the fuel tank, in particular the need to fill gasoline together with oil in a certain proportion.

Safety system with a safety device that cuts off the power tool if it comes into contact with a hard object such as a stone.

Blade condition. The use of a cutting part, made of quality materials and regularly sharpened, ensures longer operation of the clutch and gearbox.

Types of brush-drills

Gasoline drills are divided into manual and wheeled. The first are considered household appliances, the second. closer to the professional. Manual gasoline drill is preferred by most users, as it is much cheaper. its efficiency suits many, the device helps to drill holes up to 300 mm in diameter. According to the method of rotation transmission gasoline drills are divided into:

reliable and durable is considered a hydraulic structure of the transmission of rotation from the motor to the gear and auger. The load is distributed more evenly, components do not wear out as quickly and work for longer. If you have to do a lot of work, the hydraulic hand-held drill rig is the best choice.

Instructions for use

First of all it is necessary to be familiar with the safety regulations. Operating elements must not be touched during operation, because the machine can only be operated using the crank handle provided. Beforehand calculate and match the working parameters with the technical capabilities of the tool. For example if you plan to drill for piles with a diameter of 200 mm, the auger must have the same dimensions. If the machine weighs more than 10 kg, it must be operated by at least two people. It will help to perform quality work without overloading. Before starting the operation, the ground should be inspected. It is necessary to take into account that tree roots and stones can damage the blade of the tool, so it is necessary to clear the site from such elements. When your work is done, dismantle your power tool, drain the fuel and store it in a dry place.

Safety precautions

When working with a gasoline drill attention should be paid to the safe handling of the machine. Almost all machines have a system of automatic shutdown in case of loss of control, but you should not abuse it. Do not wear clothing, some of which may be caught by the auger. In this case you can get serious injury. It is also advisable to protect the eyes with glasses, because pebbles can fly out of the ground and sharp splinters out of the ice. Ear protectors for noise and of course working gloves are a good idea.

So: if you buy a power drill for professional work and frequent use in various conditions. forget about cheap and light models. You will have to splurge on a heavy motobuir with great power and increased motor life. It is also better to buy a gasoline drill for two-way operation. Such a machine will pay for itself over time.

In order to understand better how the power drill works we recommend to watch this

For amateur gardeners, there is no need for expensive machines. To make a fence around a small area and plant trees enough light and cheap Moto Digger for small amounts of excavation.

The design and technical features of the motor auger

The main part of the earth drill is the auger itself (auger), which directly digs the soil. Since the auger has a screw shape, the excavated soil is automatically fed upwards. The drill is powered by a gasoline engine.

Depending on the power of the rotary drilling rig there are two and four strokes (more powerful) motors. Fuel is gasoline grade not lower than A 92. It is necessary to add oil to fuel on the basis: gasoline. oil 25:1.

In many models of earthmoving power drills the auger part is detachable. Such devices are supplied with augers of different diameters. One should take into account that the augers produced by different manufacturers are not universal, that is why they cannot be used with other spudders. To change the augers a special tool is used, which is included with the mechanism. Besides, to dig deeper holes special extensions are made to allow the drilling depth to be increased.

To avoid injuries and traumas as well as to prevent damage to the motor the motor-drilling motor is switched off automatically. Such automation is triggered in cases where control of the tool is lost, even temporarily, as well as when the auger is in heavy soil or when it comes into contact with rocks.

The power drill is designed to be operated by one person, although professional models have a design that allows two operators to work with the drill. This option is necessary for work on heavy soils, when the physical effort of one person is not enough to control the work of the mechanism.

How to choose a garden auger?

There are several parameters for choosing the optimal version of the gasoline drill:

• Engine power. The greater the power indicator, the stronger the engine, respectively, the range of possible excavation work is wider.
• Working volume of the engine. The larger the engine volume, the stronger the torque of the auger.
• Auger diameter. The diameter of the drill depends on the diameter of the well, so it is better to have several interchangeable augers.
• The price for a power auger for excavation work

When buying a gasoline auger, it is worth determining the optimal model that is suitable for the task at hand. The fact that the price range is very wide, so one model can be many times more expensive than others. But is it worth buying the most expensive model? Definitely not.

The choice must be made depending on the indicators of the ground on which it is planned to work, as well as the intensity of use and the amount of work.

If you buy a power drill to do odd jobs like planting trees or putting up posts for fences, an inexpensive model might be enough. You can buy a lightweight mechanism that can drill wells up to 2 meters deep. Such model is suitable for black earth, loam and sandy soils. The light model of the earth drill is operated by one person.

For professional work on the regular drilling of a variety of wells in different soils, suitable expensive and heavy models, which are managed by two people.

Based on the above indicators, you should pay attention to the power of the internal combustion engine, which is measured in the usual hp.с. and its working volume. The cheap models rarely have a capacity of more than 3 liters.с. Engine displacement affects the rotational force of the auger.

For example, for clay soil, you need to choose a machine with at least 2.5 liters of power.с. and engine displacement of 40 cc or more.see. For sandy soil, these figures can be lower. a volume of 33 cc.cm and capacity of 1.5 l.с.

Choosing a gasoline auger for excavation work, special attention should be paid to the auger. You can choose a machine with a drill of the same diameter, but this is not always practical. Therefore, it is better to buy several auger diameters at once. The length of the standard auger is small and varies from 0,7 to 1 m. Better to buy an extension cord right away.

Motor-drills for professional work in any soil have a capacity above 3.5 liters. с. and are considered heavy. Such mechanism is usually operated by two operators.

Among the best quality gasoline drills should be recognized the products of such manufacturers as Husqvarna and STIHL.

Let’s take, for example, the model Husqvarna 326AI25. The machine is well adapted for engine start in the cold, so it can be used for winter drilling of soil, as well as for drilling holes. The tool is lightweight and can be operated by one person. Four augers in diameters from 130 mm to 250 mm are included. The quality of the cutting edge is very high and sharp for a long time.

Another manufacturer’s model, the STIHL BT45, is suitable for planting trees on small plots. Weight of the tool is only 5 kg, so it can be operated even by an inexperienced person. The hand-held earthmoving tool in question is designed for maximum operator comfort. With anti-vibration system and special rubber mounts for a secure grip. Can also drill into wood. The model has a two-stage engine. It also has a reverse function.

Consider also the heavy-duty model. Oleo-Mac MTL40 / MTL51. Used for drilling boreholes for street lighting poles and trees and shrubs. Powerful motor allows even the toughest terrain to be operated successfully. A special design provides the possibility of long-term work and increased durability of the engine. It is equipped with a handle that prevents accidental start of the gas pedal. Also makes changing augers or extensions quick and easy.

Efco 1585R is designed for professionals. The quality of the device is ensured by a powerful motor, which has a fuel pumping system. Forged steel crankshaft and chrome cylinder provide long service life. The gasoline drill works in any ground conditions. Operated by two operators. Emergency stop buttons on both sides of the handle.

Most powerful

Gasoline auger that is not just good, but an excellent option for a large amount of work. No problem areas or too hard ground for this tool, because it runs like a knife through butter, thanks to its power and weight. As for the weight, there is room for two people, but not as an additional feature, but an obligatory item. The tool is very heavy and almost impossible to lift alone, so you should think several times before drilling if this is the right place.

EFCO TR 1585 R 5.7 л.с.

This model is not so powerful and heavy as the previous one, but it is not inferior in performance, because it is easier to carry and get it out of the holes. small, but powerful motor does not interfere with work, but the handles are a bare metal tube, which quickly tires my hands. The machine itself is protected against overheating and can run for an extremely long time.

Oleo-Mac MTL 85 R 5.7 л.с.

• Powerful
• Productive
• Does not overheat
• Space for two people
• Reverse
• Great depth capability
• Good equipment

This gasoline auger is perfect for different soil hardness, the space for two people makes it possible to use it in problematic areas. It has a reverse function, so you don’t feel its weight during work, but you do feel its weight during transportation and it is better not to carry it alone. Pleases the indicator of the maximum depth, which is greater than that of analogues in this segment. But still, the vibrations quickly make your hands tired.

Using

The technique can be used to perform drilling in different materials to a depth of 10 m. This parameter depends on the power of the chosen equipment and its main characteristics. With this type of tool can perform the following work:

• Installation of piles for subsequent construction of various buildings.
• Installing poles for fences or barriers.
• Performing the reinforcement of the existing foundation with additional piles.
• Making holes in the ice.

How to work with a gasoline drill?

After getting acquainted with how a chainsaw works and what you need to do to make it work reliably for many years, you can move on to the next, no less important point. the selection criteria. For more information read the article “Choosing a power drill: different tools for different operations.
