Description

(W) ROTATIVE SOIL PROCESSING WORKING BODY

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to rotary tillage workers.

Rotary tillage working bodies are known, including discs with cut teeth having cutting edges p.

The main disadvantages of these discs are the uneven crumbling of the lumps in the upper soil layer and the insufficient leveling of the floor surface by the discs. Disks with incised teeth do not destroy large lumps into small lumps and only partially crush the lumps, cutting them in the direction of movement of the unit.

Closest to the present invention is a rotary soil-cultivating working body, which includes a flat disk with teeth 2j radially fixed along its periphery on both sides.

However, the known working body does not provide high-quality crumbling of the soil and cutting of plant residues.

The purpose of the invention is to improve the quality of the crumbling of boulders and the cutting of crop and plant residues.

Target d (1 is made by the fact that the disk at the end has a cutting edge, the thickness of the teeth being greater than the thickness of the tooth, and the working part of the tooth is equal to half the distance between the axes of the adjacent teeth along the chord of the disk circumference.

FIG. 1 shows the working body, side view; in fig. 2 is a section A-A in FIG. 2, in FIG. 3 - placement of teeth along the disk circumference and departure of the working part of the tooth relative to the cutting edge of the disk.

Claims (2)

A rotary tillage tool includes a disk 1 with teeth 2 radially fixed on the periphery 393 on both sides. The disk 1 is made in the form of a flat knife and has a double-sided cutting edge 3- The tooth 2 is made cylindrical with a cone-shaped tip and riveted i to the disk 1. Disk 1, due to the presence of a square hole 5 in the center of its body, is mounted along the square axis (not shown) of the gun. The thickness of the teeth 2 is greater than the thickness of the disk 1. The working part of the teeth 2 is half the distance between the axes of the adjacent teeth 2 along the chord of the circumference of the disk 1, due to which the zone of soil deformation from the impact of the buried tooth 2, characterized by a cleaving angle (L) equal to 100,105, and spreading uniformly in all directions from the cone of the tooth 2 does not reach the deformation zones of the adjacent teeth 2 on the disk 1. The soil deformation of the adjacent teeth 2 is not imposed. In addition, the ratio of the working part of the teeth 2 and the distance between them prevents seizure of soil lumps between adjacent teeth 2. The working body works as follows. When the gun moves, the teeth 2 cut into their soil cone, wedged by their cylindroidal section, with their cone-shaped tip. The cutting edge 3 of disc 1 simultaneously cuts through the soil layer, which is not split by teeth 2, and transfers crop and plant residues. Due to the introduction of the teeth 2 into the cutting surface 3 up to the cutting edge 3 of the disk 1, the depth and stability of the working member's depth in the body without sticking and jamming is provided. The use of the invention will improve the quality of soil crumbling and labor productivity. Claims of the invention: A rotary soil-cultivating tool, including a flat disk with teeth radially fixed along its periphery on both sides, in order to improve the quality of crumbling of logs and cutting of crop and plant residues, the disk has a cutting edge at the end the thickness of the teeth is greater than the thickness of the disk, and the working part of the tooth is equal to half the distance between the axes of the adjacent teeth along the chord of the disk circumference.
