For construction on the seasonal dacha the irreplaceable assistant is the petrol earth drill which saves time and forces when drilling holes for planting of trees and bushes, installation of the pile base, intaking columns and other constructions. The specific type of drill therefore it is necessary to choose it taking into account many parameters is suitable for each type of works more.
Easy petroldrills
Petroldrills for one operator are suitable for work in sandstone, the chernozem and loam up to two meters in depth. Upon purchase of such models it is necessary to pay attention to number of factors.
- Power of the unit is specified in characteristics in horsepowers and influences cost. The it is more, the work on the site will be more long and more productive to take place. At simple devices the power does not exceed 3 p/a.
- The engine displacement measured in cubic centimeters. hitachi da200e with capacity of 33 cubic cm and 1.5 p/a will be suitable for the sandy area, for example. And for clay it is recommended to take the tool from not less than 40 cubic cm: iron mole E53 (2.5 p/a, 52 cubic cm).
The motor-drill torque, i.e. the size of force which twists the screw in the earth depends on volume.
- The maximum diameter of the screw in millimeters is chosen according to what openings are required to be drilled. At opportunity it is possible to take several screws with different diameters.
Difficult petroldrills
Petroldrills under control of two operators are intended for creation of openings in solid soil, these units have power more than 3.5 p/a. There are tools and with smaller power, but they do not cope with work in dense clay though they can go with screws with a diameter of 300 mm as Hitachi da300e (2.5 p/a, 52 cubic cm). The motor-drill with the two-stroke engine, for example, of efco TR1585 (5 p/a, 80.5 cubic cm) or stihl BT 360 (4.1 p/a, 61 cubic cm) will be the best option for drilling in such earth. There are powerful models with the four-stroke engine in which, unlike duple, it is not necessary to add oil to gasoline during each filling, but they it is heavier on weight.
Councils for use
As fuel for motor-drill serves mix from gasoline and oil in the ratio 1:40 or 1:50. The engine run-in has to be made by ratio 1:25 at normal operating mode with expense of three tanks. The reducer of the device can be coaxial or worm type, between it and the engine coupling is established. During operation it is important to watch sharpness of knives that there was no premature wear of coupling and reducer.
It is easier for one operator to operate the tool with coaxial reducer as the mass of the engine is the share of drilling axis, and vibrations decrease. The worm type can be preferred on models for two operators with high power.
The earth petroldrill considerably facilitates construction on the seasonal dacha, but is applied seldom. Therefore its rent is considered the most favorable.
