FIG. one

FIELD OF THE INVENTION The invention relates to agricultural machinery industry, namely to their disk working bodies.

The purpose of the invention is to increase the productivity of the work of a disk working body by reducing traction and eliminating the formation of rolls from plant residues and filling the corrugations with soil.

; FIG. 1 shows a disk working body, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is an enlarged image of a portion of a corrugated disk with geometrical parameters of a corrugation.

The disk working body consists of a disk 1 with corrugations B, which with a rack 2 racks 2 heels to the frame 3 manshny. A device for embedding seeds is also attached to the frame.

Disk working body works as follows.

: As the machine moves towards the bottom, the disk 1 under the force of gravity of the machine sinks into the soil by 1 cub of L, i.e., to the height of the working part of the disk but its vertical axis h. The furrow formed by it provides a steady course, but the depth of the device 4 for seeding seeds.

The corrugated disk 1 when moving in the soil is included in the soil. In this case: in the phase of entry of the corrugation B into the soil, they are filled with soil.

i In order to reach the maximum correspondence of the geometrical design of the working surface of the corrugations B with the trajectories of the relative motion of soil particles taken at different depths, the initial part of the corrugations B is made with a radius of curvature (Rf - 2.1 / g) whose center is on a circle with a radius of Ru.Rp, - 1/3 / g. The execution of the corrugations B with the proposed geometrical parameters ensures their entry into the soil with minimal destruction of the latter until it reaches

their lower position, thus copying the shape of the trace of soil particles on the surface of disk 1.

Due to the fact that the main part of the work on furrowing is performed by the corrugations B as they exit from the soil, the disk tool body experiences less effort to push the soil out. Thus, the corrugated disc 1, mounted in front of the seed embedment device 4, provides

the formation of a furrow with a sufficient cross-sectional area with minimal energy costs. At the same time, due to the change in the nature of the interaction of the corrugations B with the soil, the blockage decreases

corrugated soil B, which contributes to increasing the reliability of the technological process and, consequently, increasing the man-machine productivity. In addition, by increasing the angle of entry of the cutting edges of the corrugations B, the formation of rolls from the crop residues in front of the disk is eliminated, since they are cut completely on the soil backwater. Reducing the load on the disk working body increases its durability.
