At the same time, the driven sprocket drives the feeding mechanism to transfer the material at the feeding inlet to the baling chamber for compression molding and baling operations. If it is necessary to change to a pickup picking method, the cutting table should be disassembled, the pickup should be installed, the left and right auger chains should be disengaged from the transition sprockets at both ends of the auger shaft, the left auger is welded to the left end of the pickup through the left auger chain, and the right end of the pickup is welded to the right auger through the right auger chain, which drives the pickup and the right auger weld to rotate in turn. If it is necessary to replace a pickup or cutting table with a different width for operation, the unused pickup or cutting table should be disassembled first, the double-row chain should be removed, the connection between the auger frame weld and the frame weld should be disassembled, and then the auger frame weld and double-row chain of the required width should be installed, and finally the pickup or cutting table of the required width should be installed. The present invention has the characteristics of simple structure, convenient operation, strong interchangeability, high reliability, etc. BRIEF DESCRIPTION OF THE DRAWINGS
