The film winding roller comprises a center shaft, a connection assembly and a blade; the center shaft comprises a left half shaft, a short half shaft and a long half shaft; one end of the left half shaft and one end of the long half shaft are connected with flange plates through bolts and fixed to the two ends of the short half shaft; the left half shaft is a hollow pipe, and the other end of the left half shaft is provided with two opposite notches; a pull rod is arranged in the left half shaft, and one end ofthe pull rod is located at the end, provided with the notches, of the left half shaft and provided with a gear lever; the other end of the pull rod penetrates through the flange plate, connected withthe short half shaft, of the left half shaft and enters the short half shaft; the short half shaft is a hollow pipe, and the flange plate, connected with the long half shaft, of one end of the shorthalf shaft is provided with an opening slide groove leading to the middle of the short half shaft; one end of the pull rod penetrates through an elastic piece arranged in the short half shaft and is connected with a bearing; a gasket is arranged between the elastic piece and the bearing and fixedly connected with a slide sleeve arranged in the short half shaft; and a connection lug is welded to the slide sleeve and penetrates through the opening slide groove formed in the short half shaft to be connected with a connection assembly.

Description

technical field [0001] The invention relates to the technical field of mulch film recycling equipment in the agricultural cultivation process, in particular to a film roll of a mulch film picker. Background technique [0002] With the wide application of film-laying operations in the agricultural cultivation process, while increasing crop production and income, it also brings huge challenges to the environment. The residual film remaining in the soil will change the physical structure of the soil and affect the field crops in the later stage. of normal growth. [0003] The roll film roll is one of the main working parts of the mulch film pickup machine. It mainly completes the two tasks of film roll and film unloading. With the rotation of the existing cylindrical film roll roll, the mulch film wound on the film roll rolls more and more. The tighter it is, the more difficult it is to unload the membrane, which brings great inconvenience to the membrane unloading operation, ...
