FIELD: agricultural engineering. ^ SUBSTANCE: combine has dividers, hitch, pulling unit, transverse and clamping conveyors, and combing unit. Rectangular discharge opening formed in lower part of hopper is designed for discharging of small-sized heap and is aligned with its one end with hopper rear wall so as to be hermetically closed with cover. Cover consists of two parts. One of said parts being pivotally connected to hydraulic cylinder rod aligned with axis of symmetry of cover. Other part of cover is connected through rack-and-gear drive with said one part for reciprocation of both cover parts in opposite directions. ^ EFFECT: increased efficiency through simplified small-sized heap discharge process. ^ 2 cl, 3 dwg |
