UNIT FOR HARVESTING LONG-STEM FEED Russian patent published in 2021 - IPC B02C4/02 

FIELD: agriculture.

SUBSTANCE: present invention relates to agriculture, in particular to devices for cutting, crushing long-stemmed forage crops and preparing forage. To increase the efficiency of the unit for harvesting long-stem feed, one should reduce material consumption, increase the reliability of parts and collect chopped plant mass for harvesting feed in the unit for harvesting long-stem feed having a frame 1 with a lower beam 2 and an upper beam 3, sidewalls 4, fasteners 34 of the mechanism hinges 35 on the vehicle 36 and a screen 30. There are rollers 6 in front of the screen. The rollers have disks 8 having protrusions 15 with curved sections 16 and straight sections separated by intermediate rings 9, additional intermediate rings 10, located in pairs on adjacent rollers 6, made with equal height between each other and provided with pins 22, according to the invention, the screen 30 is installed at an angle to the rollers 6, which ensures the reflection of the crushed plant mass downward, and is equipped with an unloading opening 31 with a loader 32 installed between the screen 30 and the vehicle 36. There are cleaners 29 of the rollers 6 on the frame. The cleaners are made in form of vertical plates, installed at an angle to the intermediate rings 9 to ensure the output of the crushed plant mass from the zone of the rollers 6, and additional intermediate rings 10 are made in the form of a ratchet overrunning clutch and a height equal to the height of the discs 8 and intermediate rings 9, and the disks 8 are made composite with the formation of a cavity inside the disk 8, and the straight sections of the protrusions 15 of the disk 8 are made in the form of a cutter 17 installed parallel to the axis of rotation of the roller 6.

EFFECT: invention increases efficiency of harvesting long-stem feed.
