Abstract

The invention relates to agriculture, in particular, to a device for shredding a cut vine between vineyards and spreading it for subsequent tillage. The purpose of the invention is to improve the quality of grinding the vine and reduce the energy intensity of the process. The grapevine shredder consists of frame 1, shaft 2 with 3 knives pivotally mounted by means of the hubs 3, drive 5 and supporting device 6. On shaft 2 on both sides of each knife 4 there are sprockets 7 on the bearings, fitted with counter-rays 8, mounted with the ability to interact with the soil. The cutting edge 10 of each knife 4 is made concave in the direction opposite to the rotation of shaft 2. Contradiction rays 8 are made concave in the direction of rotation of shaft 2 and have wedge-shaped soil hooks 9 with apex directed from the axis of rotation of the shaft 2. When the blades 4 rotate from the shaft 2 through the drive 5 and the rolling of the soil-hooking rays 9 as the aggregate moves across the field, the vine lying on the soil is picked up by the knives 4, fed to the counter-rays 8, between which the vine is cut and falls onto the field for subsequent tillage. 2 and. f-ly, 1 ill.

Description

The invention relates to agriculture, in particular to devices for chopping cut vines between rows of vineyards and scattering it for subsequent plowing.

The purpose of the invention is improving the quality of grinding scraps of vine and reducing the energy intensity of the process.

The drawing shows a chopper of the vine.

The chopper consists of a frame 1, a shaft 2, rigidly mounted on the shaft 2 hubs 3 with pivotally mounted knives 4, a drive 5, a supporting device 6 and sprockets 7. Asterisks 7 are mounted on the shaft 2 on both sides of each knife 4 by means of bearings (not shown) and equipped with beams-contradictions 8, installed with the possibility of interaction with the soil. Beams-contradictions 8 are made concave in the direction of rotation of the shaft 2 and have wedge-shaped couplings 9 with an apex directed from the axis of rotation of the shaft. The cutting edge 10. of each knife 4 is made concave to the side opposite to the direction of rotation of the shaft 2.

The chopper of the vine works as follows.

The rotation of the knives 4, pivotally mounted on the hubs 3, is set from the tractor power take-off shaft (not shown) by means of the drive 5 on the shaft. 2. Mounted on the shaft 2 by means of bearings, sprockets 7 with beam-contradictions 8 are rolled over the soil, with the possibility of deepening the soil loops 9 into it, with a speed equal to the speed of the unit across the field, independent of ό, τ of the shaft rotation speed 2. Lying on the soil surface, the vine is picked up by knives 4, fed to the counter-rays 8, moved along their surfaces a certain distance from the soil and cut by the cutting edge of 10 knives 4, and when large stones hit, the sprockets 7 can scroll, preventing deformation of the rays of contradictions 8 and knives 4.

Claims (3)

Claim 1. The shredder of the vine containing a frame, a shaft, rigidly mounted on the shaft of the hub with pivotally mounted knives, a drive and a supporting device, characterized in that, in order to improve the quality of chopping of vine fragments and reduce the energy intensity of the process, it is equipped with sprockets that are pivotally mounted on the shaft on both sides of each knife and equipped with anti-cut beams installed with the possibility of interaction with the soil. 2. Chopper according to π. 1, characterized in that the rays of the contradictions are made concave in the direction of rotation of the shaft and have wedge-shaped couplings with an apex directed from the axis of rotation of the shaft. 3. Chopper according to π. 1, characterized in that the cutting edge of each knife is made concave to the side opposite to the direction of rotation of the shaft.
