[0002] In recent years, with the improvement of agricultural mechanization level, cotton harvesting gradually tends to mechanization. The existing cotton picker can be divided into two-row machine, three-row machine, four-row machine and six-row machine according to the number of harvesting rows in single operation, and can be divided into box type machine and packing machine according to the cotton unloading mode. The six-row cotton picking and packing machine has high operation efficiency and low fuel and packing film use cost per unit area, but the overall width size of the cotton picker is large, which causes the problem of overwidth during the transportation process. Therefore, the walkway and guardrail need to be disassembled or folded before transportation to reduce the overall width size. The walkway and guardrail of the cotton picker have large overall mass and many types and quantities of parts, so the disassembly and later recovery are difficult, which affects the harvesting progress.
