Small self-propelled alfalfa cradling and flattening machine

The invention discloses a small self-propelled alfalfa cradling and flattening machine, belonging to the technical field of agricultural machinery. The small self-propelled alfalfa cradling and flattening machine is mainly composed of a working device, a hydraulic lifting device, an operation system, a power and transmission system and a travelling system; the working device, the hydraulic lifting device and the operation system are arranged at the front part of the machine; the power and transmission system and the travelling system are arranged at the middle rear part of the machine; one end of the hydraulic lifting device is connected with the working device, and the other end of the hydraulic lifting device is connected with the machine frame; and the power and transmission system is connected with the operation system and the travelling system through the hydraulic device, gear transmission and a transmission part. The small self-propelled alfalfa cradling and flattening machine is designed for flattening and paving alfalfas into fluffy swathes while cradling alfalfas aiming at alfalfa obtaining works in small lands, such as hills, mountainous regions and the like; a cradling table device and a flattening device are connected by adopting a frame type structure, unparallel four-connecting-rod lifting mechanisms are adopted, and when the machine climbs, a cradling table can be lifted without influencing stability of the whole machine, so that operation is safer and more stable; stepless speed regulation can be realized by driving a front axle through a hydraulic motor; the working efficiency is increased; and simultaneously, the small self-propelled alfalfa cradling and flattening machine has wider practicability.
