STRIPPING DEVICE Russian patent published in 2023 - IPC A01D41/08 

FIELD: agricultural machines.

SUBSTANCE: stripping device that can be used for harvesting grain crops. The stripping device contains a drive shaft 1 with a drum mounted coaxially on it, equipped with combs 11. The drum consists of two coaxial halves 9, 10, each of which is fixed to the drive shaft 1 by means of a set of flat springs 5, 6, 7, 8 and includes an arcuate running track 13 located in the longitudinal vertical plane, facing the concave part of its working surface towards the corresponding concave surface of the treadmill 14 of the second half of the drum. Both treadmills 13, 14 are located in the longitudinal through cavity of the drive shaft 1 and each is fixed only to the corresponding half of the drum. On the drive shaft 1 between the running tracks 13, 14, on a shaft perpendicular to the axis of the drive shaft, a rotor 19 equipped with a drive is mounted with freely rotating rollers at its ends, the axes of rotation of which are parallel to the axis of the rotor 19, and the distance between the points of the rollers most distant from the rotor axis exceeds the distance between the working surfaces of the treadmills 13, 14 in the axial direction relative to the axis of the drive shaft 1 of the drum. The ends of the treadmills 13, 14 overlap with a gap, and the working surface of the treadmill on the side of the roller movement rises above the surface onto which the roller rolls when the rotor rotates.

EFFECT: stripping device facilitates stripping of grain.
