Abstract

The invention relates to agricultural machinery, in particular to tillage tools. The purpose of the invention is to improve the quality of soil treatment. The disk harrow consists of a frame with beams 3 and frames 4 pivotally connected to them with sections of disk working bodies 6 freely mounted on axles 5. Sections 6 are mounted with the possibility of adjusting the angle of attack of disk working bodies. A shaft 7 is freely mounted on each frame 4 parallel to the axis 5, on which elastic clamping rods 9 are made between adjacent disks, made in the form of an arc of a circle with a radius of 0.8-1.2 R, where R is the radius of the disk. The rods 9 are mounted on the shaft 7 with the possibility of self-installation in the direction of movement of the harrow, the shaft 7 is placed in front of the axis 5 at a distance of 1.5-2R and above it at a distance of not more than 0.3R. In the process, the cutting of the soil with disks occurs when the rods 9 are pressed against the crop mass optimally with the rods, providing an improvement in the quality of the soil treatment. 1 s.p. f-ly, 4 ill.

Description

FIG. g

The invention relates to the field of agricultural engineering, in particular to tillage tools.

The aim of the invention is to improve the quality of tillage.

Disc harrow Contains a frame 1 with support wheels 2 and rails 3, to which sections 4 of the disk working bodies 6 are mounted pivotally on the axles x 5. In this case, sections 6 are mounted on the rake x 3 with the possibility of adjusting their angle of attack.

A shaft 7 is freely mounted on the frame 4 of each section b parallel to the axis 5, on which elastic clamping rods 9 are mounted by means of bolts 8 with the possibility of their rotation in horizontal and: longitudinally-vertical planes for self-alignment in the direction of movement within zone c. Each of the rods 9 is made in the form of an arc of a circle with a radius of 0.8-1.2R (R is the radius of the disk working body) and placed between adjacent disk working bodies with a bulge down. In this case, the shaft 7 is installed in front of the axis 5 at a distance of 1.5-2R and above it at a distance of not more than 0.3R.

Disk harrow works as follows.

In the process of processing the soil, elastic clamping rods 9 press the plant mass in the interdisk space in the zone of intersection of the disk blades with the soil surface. Cutting by soil discs occurs when tensioning rods 9

plant mass. Depending on the angle of attack, the sections of the disk working bodies b and the degree of penetration of the rods 9 are self-installing within zone c and are always oriented along the direction of movement of the harrow.

Claims (2)

1. A disk harrow, including a frame with support wheels and sections of disk working bodies, each of which is mounted on the frame with the possibility of adjusting the angle of attack, characterized in that, in order to improve the quality of soil cultivation, each section of the harrow is equipped with a freely mounted axis shaft with elastic clamping rods located on it, each of which is made in the form of an arc of a circle with a radius of 0.8-1.2 R and is placed between adjacent disk working bodies by a bulge down, the shaft is installed parallel to the section in front of it at a distance of 1.5-2R from its longitudinal axis and above the axis of the section at a distance of not more than 0.3R, where R is the radius of the disk working body. 2. The harrow according to claim 1, wherein the elastic clamping rods are mounted on the shaft with the possibility of rotation in the horizontal and longitudinal-vertical planes for self-installation in the direction of movement.
