Description

FIELD OF THE INVENTION The invention relates to CE LBSK economic engineering, in accordance with soil removal systems.

There are known povatkootdel juye devices containing hollow vpitsy and mekha "nizm drive them flj.i

The disadvantages of the known crushing devices are the damage to the cobs and the exfoliation of them from the grain due to the impact on the cobs of the protrusions of the rollers during the operation of the rudder of the yawning device, as well as the insufficient ability of the rollers.

The purpose of the invention is to increase the gripping ability of the rollers, to reduce damage to the cobs and to exfoliate the grains from them.

This is achieved by the fact that the rollers are made smooth and have longitudinal through Paaa and in the working area of their internal cavities there are drums with teeth placed in the indicated grooves.

Fig; 1 shows one of the cob separator roller, longitudinal section; in FIG. 2. An external device, a top view and section A-A in FIG. one.

The mating device contains a pair of rollers, “each of which is made of smooth drum i, inside which drum 2 is installed. On the surface 3 of roller 1, through-pass drums 4 are made, and longitudinal teeth (reefs) are made on the entire outer surface of case 5 of drum 2. 6, grooves 4 of roller 1, which are in the grooves 4

The drum 1 with the nominal bearing bearings 7 is mounted on a stationary shaft 8, moreover, in bearing supports 7 RB1EMo ёН4 BHeiuiQlH (1 section of the cage, and internally not movable. Shaft 8 rests on the sliding bearing 9. With the external holder bearing 7, the housing is attached. Drive 1O roller 1.

The drum 2 by means of bearing supports 11 is mounted on a stationary shaft 12 offset from the shaft 8 in such a way that the teeth (reefs) 6 of the drum 2 extend from the grooves 4 of roller 1 beyond its limits only in the rolling zone of the stalks. The shaft 12 of the drum 2 is connected to the shaft 8 of the roller 1 by means of releasable cheeks 13. The pick-up rollers work as follows. When the drive sprocket 10 rotates, the torque is transmitted to the outer race of the bearing support 7 and the roller shaft 1. When the drum 1 rotates, the teeth 6 entering the grooves 4 of roller 1 cause the drum 2 to rotate. Since the shaft 12 of the drum 2 is offset from shaft 8 of drum 1, then the tooth 6 of the grooves 4 beyond the outer diameter of the drum 1 only in the rolling zone of the stems - l. ;. h --.-: A cut stalk is brought to the position of 3 branches to the caliber rollers 1, 6 drums 2 are rolled with the teeth and rolled with the barbolt rollers in the working slot. /. . The crushing, meeting the resistance of the smooth surfaces of the rollers 1, is detached from the stalks. The presence of teeth on the surfaces of the housings 5 drums 2 uiaet active Thus, the proposed stripping device has an increased 6-6 activity in the rolling zone of the stems, as a result of which the rolling of the stems and the quality of the detachment take place faster, eliminating the clogging of the popping unit by the stems. The productivity of the corn harvesting machine is increased by equipping with the proposed chopping device. Damage to the coils and the vyschelushyvayyuyey their grains is eliminated, because the teeth coming out of the grooves 4 of roller 1 do not affect the cob, as they exit only in the rolling zone of the stems, and a smooth shaft 1 prevents the ingress of the cob into the rolling zone of the stems m ohm from pochtKotdet pokhodeni younger device containing hollow rollers and the mechanism of their drive, which means that, with a chain of increasing the exciting ability of the rollers, reducing damage to the cobs and flaking out of them, the rollers met, smooth and and have longitudinal through grooves, and in the working area of their internal cavities there are drums with teeth placed in the said grooves.
