High-efficiency crawler-type pickup baler and automatic bale stacking system

A high-efficiency crawler-type pickup baler and bale stacking system, comprising a straw pickup and stubble harvesting device, a continuous conveying preloading device, an under feeding type compression and binding device, a walking device and a control system,

• wherein the continuous conveying preloading device, the under feeding type compression and binding device, a bale conveying and arraying device and the bale stacking device are all arranged on a frame of the walking device;
• the straw pickup and stubble harvesting device is mounted on a third axis of a grass discharging wheel of the continuous conveying preloading device, an opening at the rear end of a pick up the straw stubble harvesting device and a feed throat of the continuous conveying preloading device are connected, the continuous conveying preloading device and a feed throat of a under feeding type compression and binding device are connected through a hood;
• wherein the straw stubble harvesting device includes a pickup attachment, a cutting and conveying mechanism, a first hydraulic motor, a hydraulic updown mechanism;
• a cutting and conveying mechanism which includes a header frame, an auger on a header frame, a cutting knife, a header extension holder;
• wherein the header frame is fixed on a third axis of a straw discharging wheel, the cutting knife is mounted in the front of header frame, the cutting knife is driven by the first hydraulic motor in a reciprocating cutting movement for harvesting stubble field;
• a header extension holder is fixed on the header frame and the axis of a straw discharging mechanism are connected by a bearing;
• a header conveying auger is mounted on a cutting table frame by a bearing and rotatable under the drive of the first hydraulic motor;
• a coping pick-up mechanism includes a coping sliding plate, a copying wheel, a copying frame, a spike-tooth cylinder, wherein the coping frame is connected via the first axis to the header frame, under the rear of the copying frame welded frame holder;
• the welded frame holder on which on the header frame is adapted to be held when header frame up, supporting the copying pickup mechanism weight;
• coping sliding plate and the copying wheel are mounted on the coping frame through a bearing, below the coping frame the rear of the coping frame and the upper end of the side of the header frame is connected by a first tension spring and first connecting bolts, forming a coping frame lever structure on which the fulcrum is a first axis;
• the first tension spring is in a tensional state pressure whereby to press the coping picking mechanism toward the ground and resulting in the coping sliding plate and coping wheel being pressed close to the ground;
• a spike tooth roller mounted on the second axis driven by the first hydraulic motor, and a roller rotatable around the second axis mounted in the copying frame;
• at the rear-end of the cylinder of the first hydraulic cylinder in the hydraulic lifting mechanism and a frame of the walking device are connected and rotatable around the second pin through the second pin, in a front of a hydraulic rod in the first hydraulic cylinder and a tail end of an ear on the header frame are connected through the third pin and rotatable around the third pin;
• the walking device is equipped with a speed measuring radar on its frame, and the speed measuring radar is connected to a control system;
• the control system is connected to the first hydraulic motor, according to a speed of binding machine measured of the speed measuring radar with respect to a forward speed, reaches a speed of spike-tooth roller and a speed of cutter cutting speed linkage adjustment by adjusting an output speed of the first hydraulic motor.
