A film roll of a mulch pick-up machine

Abstract

The invention discloses a film roll for a mulch picker, which comprises a central shaft, a connecting component, and blades; the central shaft includes 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 pass through a bolt The connecting flange is fixed at both ends of the short half shaft; the left half shaft is a hollow tube and the other end of the left half shaft is provided with gaps opposite to each other, and a pull rod is arranged inside the left half shaft, and one end of the pull rod has a gap on the left half shaft One end is provided with a gear rod; the other end of the pull rod passes through the flange connected to the left half shaft and the short half shaft and enters into the short half shaft; the short half shaft is a hollow tube and connected to the long half shaft at one end The flange is provided with an open chute leading to the middle of the short half-shaft; one end of the tie rod is connected to the bearing through the elastic part arranged in the short half-shaft; a gasket is arranged between the elastic part and the bearing, and the gasket is fixedly connected. The sliding sleeve in the short semi-shaft is welded with connecting ears, and the connecting ears pass through the opening chute on the short semi-shaft to connect with the connecting 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, ...

[0003] The roll film roll is one of the main working parts of the mulch film picker. It mainly completes the two tasks of film roll and film unloading. With the rotation of the existing cylindrical film 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 and low operating efficiency
