BEATER DRUM Russian patent published in 2021 - IPC A01F12/18 A01F7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to threshing beater drums, which can be used in combine harvesters. The beater drum contains the drive shaft with the bearing disks installed on it for installation of removable metal composite whips with oblique reefs that are multidirectional from the joint by means of whip stands or directly on the generatrix. The joint of multidirectional reefs is shifted towards the field divider from the middle of the beater drum by up to 0.25 of the length of the beater drum. The slope of the reefs in odd-numbered whips is directed in the course of rotation in different directions from the joint, and in even-numbered whips, it is directed to the joint. Even and odd whips are installed in any order, both among themselves, and with solid whips with a unidirectional slope of the reefs along the entire length of the whip, or in any variant set in number and order with whips with another working surface of different shapes. The total number of places for whips on the beater drum must simultaneously be a multiple of the numbers 2 and 3. The drum can be made in the form of a closed hollow cylinder with trough-shaped whip stands fixed to the generatrix.

EFFECT: beater drum is characterized by high technological efficiency.
