The invention discloses a ridge crossing device of a rice harvester. When the rice harvester needs to cross a ridge, the rice harvester stops in advance, then a main hydraulic cylinder moves, a piston rod of the main hydraulic cylinder extends outwards to jack one end of a rotating rod up, simultaneously an auxiliary hydraulic cylinder performs coordinated movements to assist the rotating rod in reversing, a support frame is arranged at a low position, travelling wheels are in contact with the ground firstly, the piston rod extends outwards continuously along with the movements of the main hydraulic cylinder and the auxiliary hydraulic cylinder, the front end of the rice harvester is jacked up to be higher than the ridge, then the travelling wheels are driven by a hydraulic motor to rotate, the rice harvester moves forwards till cross the ridge, and after the rice harvester crosses the ridge, the main hydraulic cylinder and the auxiliary hydraulic cylinder move simultaneously, to maintain the support frame to be stored in the harvester at a vertical state. By applying the ridge crossing device of the rice harvester, the problems of low efficiency and high labor intensity of traditional ridge crossing equipment are solved, and the ridge crossing device of the rice harvester has the advantages of being simple in operation and unlikely to get into muddy fields.
