HARVESTER FOR GRAIN SORGHUM Russian patent published in 2023 - IPC A01D41/08 A01D41/127 A01D75/28 

FIELD: agriculture.

SUBSTANCE: harvester for grain sorghum contains a self-propelled chassis (1), a hydraulic hitch (2), a hopper (3), a harvester (4), a plant conveyor (5), two or more modules (6), each of which includes a direct-flow remote threshing chamber (7), normalizer (8), intermediate conveyor (9) and synchronizing gear (10), plant chopper (11), chopped mass spreader (12), pressing device (13) and tilt sensor (15). Hydraulic hitch (2), hopper (3), direct-flow remote threshing chamber (7), normalizer (8), synchronizing gear (10) and tilt sensor (15) are mounted on a frame (14), additionally mounted on a self-propelled chassis (1). The frame (14) is connected to the self-propelled chassis (1) on one side with respect to its longitudinal axis by means of hinges (16), and on the other side, a hydraulic cylinder (17) is installed between the frame (14) and the self-propelled chassis (1). The tilt sensor (15) is made in the form of a tube, at the ends of which microswitches are installed, and inside it there is a ball that can move from the middle position of the tube to one or the other extreme when the self-propelled chassis (1) is tilted to one or the other side, respectively, with respect to its longitudinal axis. One of the microswitches closes and sends a signal to the electric hydraulic distributor (21), which controls the supply of working fluid to the corresponding cavity of the hydraulic cylinder (17).

EFFECT: possibility to install the hydraulic hitch, modules and the hopper of the combine in a horizontal position when harvesting grain sorghum by the combine when it moves across the slope of the field.
