Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, tools for digging for planting bushes and trees. The purpose of the invention is to reduce energy consumption and prevent the soil being poured out into manufactured mu. The drill contains a hollow shaft 1, inside of which a movably hollow reinforced cylinder 2 is placed, auger winding 3, a window 4 with a bent visor 5 and a ploughshare 6. When working, the soil moves along the helical auger winding 3 and the obstacle in the form of bent visors 5, falls into the window 4 of the hollow shaft 1 and the holes of the hollow reinforced cylinder 2. When the reinforced cylinder is filled with soil, it is removed from the hollow shaft 1 to clean the soil while the screw auger is in the ground. After cleaning, the reinforced cylinder 2 is inserted into the auger for subsequent penetration into the ground. 1 hp ff, 2 ill.

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, tools for digging for planting bushes and trees.

The purpose of the invention is to reduce energy consumption and prevent the soil being poured out into manufactured mu.

FIG. 1 shows a drill; FIG. 2 is a section A-A in FIG. one,

The drill contains a hollow shaft 1 within which a movably hollow reinforced cylinder 2 is placed. The cylinder is made reinforced to crush the soil when it enters the cylinder. From the elevation side of the screw winding 3, a window 4 is made at its base with a bent visor 5 in height. The visor 5 is bent relative to the surface of the shaft 1 at an angle a of 90 ° to get the soil into the window. The surface of the screw winding 3 is made with a bias in the direction of the shaft 1 and the plowshare 6,

The drill works as follows.

A plow part, which is made at the shaft end, is installed above the mark of the location of the future hole and begins the process of digging the drill by rotating the screw 3 around the axis. As the drill is buried in the ground, the soil, moving along the screw-like screw coil 3 and meeting an obstacle in the form of bent peaks 5, falls into the windows 4 of the hollow shaft 1 and the holes of the hollow reinforced cylinder 2.

(7) at an angle of not more than 90 °, since the flow of the soil, which rises along auger winding, is perceived by the visor 5 with this establishment and is directed partially in

a zone of hollow reinforced cylinder 2, which in turn produces additional loosening of the soil. When the reinforced cylinder is filled with soil, it is removed from the hollow shaft 1 to remove soil from it.

while finding the auger drill in the ground. After cleaning, the reinforced cylinder 2 is inserted into the auger for subsequent penetration into the ground.

Claims (2)

The proposed implementation of the drill can increase the reliability of its work, improve the quality of crumbling of the soil and, consequently, increase the yield. Invention Formula 1, a drill comprising a shaft along which a screw is fastened, characterized in that, in order to reduce energy consumption and prevent the soil being poured out into the manufactured soil, the shaft is hollow and equipped with it is a hollow movable reinforced cylinder, with windows along the shaft with lateral bent-over visors located above the screw winding to guide the soil into the cylinder. 2. Bur POP.1, characterized in that the visor is bent relative to the shaft surface at an angle of 90 °.
