COMBINE HARVESTER FOR GRAIN SORGHUM Russian patent published in 2023 - IPC A01D41/08 A01D41/12 A01D45/02 A01D75/02 A01F12/60 

FIELD: agriculture.

SUBSTANCE: combine for harvesting grain sorghum contains self-propelled chassis (1), hydraulic hitch (2), replaceable hoppers (3), a harvester, a plant conveyor, direct-flow external threshing chamber (6), normalizer (7), an intermediate conveyor, plant chopper (9) , crushed mass spreader (10), system (11) for supplying grain from a direct-flow external threshing chamber to a replaceable hopper and a mechanism for replacing hoppers. The hopper replacement mechanism includes platform (13) and base (14), compensating tank (15), end sensors (16), control relay (17) for grain supply system devices and an electric motor for the hopper replacement mechanism. Below each replaceable hopper (3), there is a transportation device (19) for its transportation from the combine to the grain unloading place and return after unloading of the grain, which includes support beam (20), a power source in the form of battery (21), obstacle detection unit with ultrasonic sensor (22), and an undercarriage. The running system contains two locomotion devices (23) installed in parallel to each other, each consisting of a drive wheel equipped with a variable speed electric drive, a guide wheel, a caterpillar belt with its tensioning device. Transport device (19) for the replaceable hoppers and self-propelled chassis (1) are equipped with mobile communication stations (30), and the electric drives of the driving wheels of locomotion devices (23) of the undercarriage are connected to the control unit. EFFECT: reducing the time spent on collecting replaceable hoppers filled with grain from the field and loading them into a vehicle and returning empty replaceable hoppers to the combine.
