THRESHING DEVICE Russian patent published in 2004 - IPC

FIELD: agricultural engineering.

SUBSTANCE: proposed threshing device has drum and deck. Working members in form of bases with rows of curved teeth of equal length are installed on surface of drum. Traces of adjacent teeth partially overlap each other. Length of bases is smaller than length of drum. Locks are made on ends of drum in form of extension of working member base. Length of locks of one working member is equal to difference between length of drum and base. Difference between lengths of locks arranged from one edge of drum on adjacent working members is equal to pitch of tooth traces. Use of locks for required arrangement of working members of drum precludes wrong arrangement of working members when worn-out working members are being replaced.

EFFECT: facilitated servicing.
