Abstract

Usage: no-tillage and deep loosening of the soil. SUMMARY OF THE INVENTION The device comprises a rack with additional working elements with cutting edges mounted on the lower end of its working part, and they are made in the form of plowshares mounted at an angle of 90-100 & to each other and at an acute angle of attack 2 silt

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery industry, in particular, to working bodies for basic soilless tillage and deep loosening of the soil.

Known working body for soilless tillage, loosening the rack which is made zigzag.

The disadvantages of the well-known working pit are high metal consumption, high traction resistance and energy consumption of tillage due to the large area of friction.

Also known is the design of a deep-ripper, containing a stand with chisels and fixed at an acute angle to it and one to another additional stands with chisels.

The disadvantage is the high energy consumption of tillage, due to the blocked cutting of additional bits.

The purpose of the invention is to reduce the energy consumption of soil-free tillage.

The goal is achieved by the fact that in the working body for soilless tillage, consisting of a rack located in the longitudinal-vertical plane and fixed at its lower end at an angle to the horizon of the working elements, the latter are set at an angle of 90-100 ° to each other of them made in the form of a plowshare. Moreover, each plowshare is located at an acute angle of attack and has a sharpened trailing edge.

Figure 1 shows the working body in a recessed position with the scheme of loosening the soil, front view; figure 2 is the same, right view.

The working body for soilless tillage consists of a rack 1 with plowshares 2 and 3, the camber angle / 3 of which is 90-100 °. The length of the projection of the I plowshares 2 and 3 on the transverse vertical plane is equal to the height of the working part h of the pillar 1. The cutting edges 4 of the plowshares 2 and 3 form an acute angle of attack y with the direction of movement and are sharpened from the occipital side with an angle; smaller cutting angle a. plowshares 2 and 3

The working body works as follows.

When the working body moves under the action of the weight of the gun and the vertical component of the soil reaction to the blades 2 and 3 installed at an acute angle of attack, it deepens into the working depth H, which corresponds to a full immersion of the working part 1 in the soil. and 3 cuts off the soil layer and, as an element of a trihedral wedge, displaces it, destroying the monolithic structure without compaction of the lower layers and the formation of a plow sole.

By installing the plowshares 2 and 3 at an angle of 90-100 ° to each other, the direction of the action of the plowshares coincides with the direction of spallation of the soil. This ensures a reduction in traction resistance. Due to the equal length of the projection of the I-share projection on the vertical-transverse plane and the height h of the working part of the stand, the area S of the working body per unit length of the working part of stand 1 and share 2 and 3 increases, the dimensions of the breakup grooves are reduced. This increases the distance between the working bodies, increases productivity and reduces energy consumption.

Sharpening the cutting edge 4 from the occipital side with an angle I less than the crumbling angle also contributes to reducing the cutting force and energy consumption for tillage.

The proposed tool body at the main soilless tillage to a depth of 25-35 cm ensures continuous loosening of the soil surface to a depth of 15-20 cm, which meets the agrotechnical requirements imposed on chisel-type working bodies.
