Abstract

The invention relates to the field of agricultural machinery and can be used in machines for harvesting root crops and onions. The purpose of the invention is to increase work efficiency. The camber-destructive device consists of overlapping and opposing rollers 1 and 2. Inside the lower roller 2 there is a fixed cylinder 4 fixed to the shaft 3, inside which is mounted a rotating screw 7. The cylinder 4 has a window facing the upper drum. The working surface of the drum 2 is mesh. One of the ends of the roller 2 is connected to the shaft 3 by means of the sidewall 8. The other end is fixed on the stationary cylinder 4 by means of the rollers 10. On this side, the end of the stationary cylinder, made in the lower part open, stands behind the end of the roller 2 to unload the separated soil and vegetable impurities. When the rollers capture the lumps, the latter are destroyed and through the window of the stationary cylinder 4 enter the zone of operation of the screw 7, with which they are carried into the field. 1 il.

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in machines for harvesting root crops and onions.

The purpose of the invention is to increase work efficiency.

The drawing shows a diagram of the lump-breaking device of the harvesting machine - root and tuber crops and onions.

The comrade device consists of upper and lower counter-rotating rollers 1 and 2 arranged one above the other. Inside the lower roller 2 there is a fixed cylinder 4 fixed to the shaft 3, inside which, in turn, a screw 7 is mounted on the shaft 3 by means of bearing assemblies 5 and 6. Cylinder 4 has a window facing the upper drum 1. The working surface of the lower drum 2 is made mesh. One of the ends of the roller 2 is connected to the shaft 3 at

using the sidewall 8 fixedly mounted on it. The other end is fixed to the ring 9 enclosing the fixed cylinder 4 with three rollers 10 that are in contact with the treadmill 1 1 of the cylinder 4 at an angle of 120 °. An asterisk 12 is installed on the shaft 3 from the sidewall 8. On the opposite side, the end of the stationary cylinder 4, made open in the lower part, stands for the end of the drum 2 by an amount that ensures that the separated soil and plant impurities enter the track of the machine.

The device works as follows.

When the harvester moves across the field, the mass supplied to the lump-breaking device is captured by the rollers 1 and 2 and, when passing through, is subjected to compressive forces. At the same time, the components of the mixture experience mainly deformation

ABOUT

(Shiba, as they rest on the mesh surface of the roller 2, which leads to the appearance of bending moments. Clumps are effectively destroyed, spill through the mesh surface of the drum 2 and then through the window of the fixed cylinder 4 enters the zone of operation of the screw 7, which is carried beyond the dimensions devices in a zone of a track of a running wheel of the car.
