Description

(54) SOIL-PROCESSING MACHINE

one

The invention relates to agricultural machinery, in particular to soil tillage milling machines.

Known tillage machines with a working body, made in the form of a milling drum with knives 1.

However, such machines provide good quality of loosening the soil only with small feeds to the knife, and this requires either an increase in the rotation frequency and, consequently, an increase in efficiency, or a decrease in the translational speed.

A soil tillage machine is known that includes a frame, a shaft, working bodies mounted on the shaft alternately rigidly and freely and interconnected by a gear 2.

However, this machine does not effectively grind plant residues.

The purpose of the invention is to improve the grinding of plant residues.

The goal is achieved by the fact that the freely mounted working bodies, placed on opposite sides of rigidly fixed working bodies, are interconnected in pairs by the ends of the cutting edges.

FIG. 1 shows a soil tillage machine, top view; in fig. 2 - section of the working bodies.

The tillage machine includes a frame 1 on which the shaft 2 is fixed with the working bodies 3 and 4. The working bodies 3 are fixed on the shaft 2 rigidly, and the working bodies 4 are loose. RA 5 organs 4

are located on both sides of each row of rigidly fixed working bodies 3 and are connected in pairs by the ends of the cutting edges. In addition, the working bodies 4 are interconnected muftamn 5

and with the shaft 2 through a planetary gearbox, which includes the driven gear 6, intermediate 7 and leading 8. Driven gear b is connected to the block of working bodies 4, and the leading; gear 8 is rigidly fixed on the shaft 2. Shaft 2 can be driven by the tractor's power take-off shaft (not

shown) through gearbox 9 and gear 10:

The machine works as follows.

In the absence of the drive from the selection shaft

when working, the power units 4 are rolled into the soil and create a torque transmitted through the planetary gear (gears 6, 7 and 8) to the shaft 2, thereby providing different angular speeds of the working bodies 3 and 4. At the same time, the working bodies 4, pairwise connected by cutting edges, they cover working bodies 3 and play the role of an antitheft device, improving the quality of grinding plant residues and preventing their bodies from clogging. When a drive is present, the machine works as a milling cutter with two milling machines: internal, formed by working bodies 3, and external, formed by working bodies 4. The planetary gear provides different angular velocity of the milling machines and improves the grinding of plant residues.
