FORAGE HARVESTING MACHINE Russian patent published in 2022 - IPC B02C4/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for cutting, grinding long-stemmed forage crops and forage harvesting. The machine contains a frame 1 with a lower beam 2 and an upper beam 3, sidewalls 4, fasteners 39 of the hitching mechanism 40 on the vehicle 41 and a screen 35. In front of the screen 35 there are rollers 6 with disks 8 having protrusions 15 with curved sections 16 and rectilinear sections 17, separated by intermediate rings 9. Additional intermediate rings 10 are arranged in pairs on adjacent rollers 6, are made with equal height between each other and are provided with pins 27. The screen 35 is mounted at an angle to the rollers 6, providing a reflection of the crushed plant mass downwards, and is equipped with an unloading hole 36 with a loader 37 installed between the screen 35 and the vehicle 41. On the frame 1, there are cleaners 34 rolls 6, made in the form of vertical plates mounted at an angle to the intermediate rings 9 to ensure the output of the crushed plant mass from the zone of the rolls 6. Additional intermediate rings 10 are made in the form of a ratchet overrunning clutch and have a height equal to the height of the disks 8 and the intermediate rings 9. The disks 8 are composite with the formation of a cavity inside the disk 8 and are equipped with replaceable rims 21, copying their shape. The sections of the replaceable rim 21 corresponding to the rectilinear sections 17 of the protrusions 15 of the disk 8 have peak-shaped blades 23 mounted parallel to the axis of rotation of the roller 6.

EFFECT: use of the invention will increase efficiency of the forage harvesting machine.
