MOBILE THRESHER Russian patent published in 1995 - IPC

FIELD: agriculture. SUBSTANCE: thresher has two additional technological lines and a new design of intake-batching unit. The latter has intake conveyors 1 and delivery-lifting conveyor 2. Intake conveyors 1 are installed in steps one above the other throughout the height of the rick and are enclosed, together with concave beater 3 and equalizing conveyor 4, in housing 5 installed on delivery-lifting conveyor 2. The latter is secured on platform with crawler running gear 6 moving in synchronism with the belt of conveyor 2. Installed on base machine under technological line 7 comprising pin drum 8 with grate bottom are two additional technological lines of which the upper one comprises drum-type pick-up 9, vibrating bar grate 10, front conveyor 11, auger 12, intermediate conveyor 13, supplementary threshing device 14, inclined conveyor 15 while the lower one has fan 16, grate 17, transverse auger 18 with receiver, elevator 19, and hopper with unloading device. The base machine is articulated with intake-batching unit by means of hydraulic lifting cylinder 21 in which the end surfaces of casing and rod are attached, respectively, to frame 22 of the base machine and to housing 5 of intake-batching unit. EFFECT: reduced damage, lower losses of grain, higher productivity and operating reliability of thresher. 4 cl, 1 dwg
