Wide-width folding stubble cleaner stepless variable speed multi-point sectioned driving device

The invention discloses a wide-width folding stubble cleaner stepless variable speed multi-point sectioned driving device. The driving device comprises a main rack, folding racks, a hydraulic system, driving boxes, a main gearbox, a folding mechanism, a folding hydraulic cylinder and the like. Stepless variable speed adjustment of 0-500 r/min of working parts can be achieved according to the actual conditions, hydraulic motors independently drive the five sets of working parts through the driving boxes, five-point sectioned independent driving is achieved, and the situation that parts of the working parts work and parts of the working parts do not work can also be achieved according to the actual operation requirements. According to the driving device, the requirements of different ground conditions and different geographical regions for different rotational speed output of the working parts are well met, and meanwhile the adaptability requirements for different widths can also be met. 本发明公开了种宽幅折叠灭茬机无级变速多点分段驱
