OPTIMIZATION OF OPERATION AT THE FOUR HARROW
Description
Disc tools are designed for the surface treatment of the soil, as well as for loosening and preparing the soil for planting, weed control and grinding residue, for seedbed preparation without preliminary plowing in the system of minimum tillage technology and after thick stem row crops harvesting. It implements a disk type implements include a disc mounted on the individual rack. Classical instruments of this type are made with a rigid stand mounting the cutter body to the frame. In the classical working body attachment scheme has a number of disadvantages. One of them is the lack of a safety element. The proposed version of the working body of the fastening using a spring strut has the following advantages. When zooming in on the disc obstacles (dense soil, bump, pit, stone), flexible disk drives backward, up, down or to the side (left, right) by the spring property (elasticity) of the curved rack. This design reduces the shock load on the bearing assembly, wherein the disc is returned to the original position by passing earth and crop residues without blockage. The purpose of structural changes was to reduce the energy intensity of the surface treatment process of the soil while improving reliability
