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 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 straw discharging wheel of the continuous conveying preloading device, an opening at a rear end of the straw pick up and 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 the 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, and a hydraulic updown mechanism;
• wherein the cutting and conveying mechanism includes a header frame, an auger on the header frame, a cutting knife, and a header extension holder, wherein the header frame is fixed on the third axis of a straw discharging wheel, the cutting knife is mounted in the front of the header frame, and the cutting knife is driven by the first hydraulic motor in a reciprocating cutting movement for harvesting stubble field;
• wherein the header extension holder is fixed on the header frame and the axis of the straw discharging wheel connected by a first bearing;
• and 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 which includes a coping sliding plate, a coping wheel, a coping frame, and a spike-tooth cylinder, wherein the coping frame is connected via a first axis to the header frame, under a rear of the copying frame welded frame holder;
• the welded frame holder on which on the header frame is adapted to be held, supporting the coping pickup mechanism;
• wherein the coping sliding plate and the coping wheel are mounted on the coping frame through a second bearing, below the coping frame at a rear of the coping frame, and an 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 in which a fulcrum is a first axis;
• a first tension spring which is in a tensional state pressure adapted to press the coping pick-up 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 a second axis driven by the first hydraulic motor, and a roller rotatable around a second axis mounted in the coping frame;
• a rear-end of a cylinder of the first hydraulic motor in the hydraulic lifting mechanism and a frame of the walking device are connected through a second pin and rotatable around the second pin, in a front of a hydraulic rod in the first hydraulic cylinder and a tail end of a rear on the header frame are connected through the third pin and rotatable around the third pin;
• wherein the walking device is equipped with a speed measuring radar on its frame, and the speed measuring radar is connected to the control system;
• and
• wherein the control system is connected to the first hydraulic motor, according to a speed of binding machine measured by 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.
