AXIAL-ROTOR THRESHING-SEPARATING DEVICE FOR CORN COBS IN LEAF WRAPPER Russian patent published in 2024 - IPC A01F11/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in threshing corn cobs uncleaned from leaf wrapper. Axial-rotor threshing-separating device comprises loading hopper 1 with inclined 2 and horizontal 3 feed conveyors, upper half-deck 4 with tenons 5 on inner surface, lower half-deck 6 with tenons 5 and holes 7 for grain discharge, rotor 8 with gripping screw blades 9 in lead-in part, main rod winding 10 in threshing-separating part and additional rod winding 11 in final threshing part, geared motor 12 to drive rotor 8, compressor 13, air manifold 14 connected to the unit of radial 15 and axial 16 air ducts. Radial 15 and axial 16 air ducts are located in the area of the discharging window of the threshing-separating device, installed in the final threshing part of the lower half-deck of the spring-loaded section of sieve 17 with vibration motors 18, wherein threshing-separating device comprises frame 19, separating sieve 20, grain hopper 21, discharge mouth 22 with inclined sieve 23.

EFFECT: invention ensures minimization of grain losses through the unloading window.
