The invention relates to agricultural machinery, in particular to machines for digging planting for perennial plantings.

The purpose of the invention is to increase the productivity of digging m on heavy soils or by means of small-scale mechanization.

The drawing shows a drill while we are digging. ..

The drill consists of an axial pipe 1, on which the screw 2 and bracket 3 with a perk 4 and two diametrically located shares of plowshares 5 and 6 are fixed: distant from the axial pipe with a smaller pickup width and near from the axial pipe with a larger pickup width, respectively.

The drill works as follows.

The drill is set above the mark. the future we are driven into rotation. And under the action of the feed of the burial it enters the soil. At the same time, the perk 4 extends into the soil, forming the space for the passage of the axial tube 1, then the plowshares 5 and 6. The plowshares are located at different distances from the axis of the drill so that the plowshare .5 cuts the soil closer to the edge, and the plowshare 6 - closer to the drill axis, the blades 5 and 6 do not overlap each other’s tracks and, together with the perk 4, provide for cutting the soil across the entire diameter of the we. For both, the liver of a symmetrical load on the axial tube of the plowshares is made with unequal capture grip, determined from the condition of providing the same cutting force on each of the plowshares:

Solving (3), it is possible to obtain practical values of a and b for specific values of drill diameters.

The arrangement of the plowshares in the diameter of the drill without overlap leads to the possibility of increasing the thickness of the cutting soil chips by 2 times compared with the known drills with the same depth feed, which allows cutting of chips of greater thickness than the thickness of the compacted soil layer. Consequently, the effort to cut the soil during the burial does not increase and there is no need to reduce the flow of the burial. As a result of this, we dig

greater productivity than the use of well-known Boers.

Upon reaching the required depth of digging, the drill is deepened from the we.

The application of the invention will also improve productivity by creating favorable conditions for digging out rocky inclusions in the soil, as during the process of digging it is possible to alternately meet the plowshares with the stones, and the likelihood of the plowshield to meet the lower part of the stone increases. facilitates the excavation of stones from the soil.

In this case, it becomes possible to use limited capacities of small-scale mechanization equipment for digging up by creating the possibility
