Abstract

1. SOIL PROCESS AREA TOOL containing established; spherical discs and spacers between them are axially characterized in that, in order to increase operational reliability by increasing the strength of the discs, diametrically arranged and directed in different directions are made on the surface of each disc. Each facet has a shape of a truncated spherical surface, a concentric disk sphere, a trapezoidal pyramid, and at the ends of each of the spacer sleeves (L are made diametrically arranged grooves, each of which has one of the bulges of the disk. O) CX)

Description

2. Tool POP.1, characterized in that the protuberances of each disk, directed in one direction against its surface, are perpendicular to convexity, directed in the other direction.

3, The tool according to claims 1 and 2, about t l and so that the ratio of the diameter of each spacer to the length of each bulge is equal to

The invention relates to agricultural machinery, namely to tillage tools with passive disk working bodies,

The purpose of the invention is to increase the operational reliability by increasing the strength of the disks.

Figure 1 shows the tillage tool, front view, figure 2 - section aa in figure 1; fig.Z - disc with spacers; figure 4 - view B in fig.Z; on fig.Z view In fig.Z.

The tillage implement contains spherical disks 2 mounted on axis 1, spacers 3 and stops 4 arranged between them. Axis 1 is mounted on bearing supports 5, which are connected with brackets 6. The sequence e is fixed on frame 7. On the surface of each of The disks 2 are made diametrically located and directed in different directions from the surface of the disk of the bulge 8, each of which has the shape of a truncated spherical surface, a concentric sphere of the disk 2, a trapezoidal pyramid.

At the ends of each of the spacer sleeves 3, diametrically arranged grooves 9 are made in which bulges 8 of disc 2 are located. The bulges of disc 2, directed to one side of its surface, are perpendicular to bulges directed to the other side, and the ratio of the diameter of the spacer 3 the length of the bulge placed in its grooves 9 is 8 3: 4, while the portions of the bulge 8 that are placed outside the groove 9 are tapered. Disks 2 and spacers are mounted on axis 1 with screw connection tO.

The proposed tool works as follows.

When the guns move along the cultivated area, the disks 2, rotating from the reaction forces of the soil, loosen the soil. Spinning discs

is transmitted to the sleeves 3 and the stops 4.

 .

The application of the invention will improve the strength of the discs and, accordingly, the operational reliability of the gun, eliminating the possibility of discs, spacers and axles slipping and breaking.

1. SOIL PROCESSING TOOL, containing spherical disks mounted on the axis and spacer bushings located between them, characterized in that, in order to increase operational reliability by increasing the strength of the disks, diametrically located and directed in different directions from the disk surface are made on the surface of each disk bulges, each of which has a shape with a truncated spherical surface, a concentric sphere of a disk, a trapezoidal pyramid, while at the ends of each of the spacer sleeves are made iametralno located grooves, in each of which one of the bulging disk is placed. Figure 1 2. The gun according to item 1 is distinguished by the fact that the convexities of each disk directed in one direction στ of its surface are perpendicular to the convexities directed in the other direction. '3. The gun according to claims 1 and 2, characterized in that the ratio of the diameter of each spacer sleeve to the length of each bulge is 3: 4;
