Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a picking roller of a residual film recycling machine. BACKGROUND

[0002] Although the mulching film has significant effects on heat preservation, soil moisture preservation and water saving during the growth of crops, its non-degradable characteristics also seriously pollute the soil. Therefore, the recycling of waste mulching film has always been the focus of agricultural planting. In recent years, the degree of mechanization of residual film recycling has also been increasing, but the overall process is still in its infancy. The key problem to be solved in the process of mechanized operation of residual film recycling is the picking and separation of residual film and film debris. At present, the picking methods of residual film generally include roller type and chain rake type. The chain rake type directly picks up residual film from the soil through the film picking teeth fixed on the chain rake. The roller type picks up residual film from the soil through the film picking teeth fixed on the roller, and then separates the picked residual film from the roller to the film collecting device (film collecting box or packing machine) through a film separating impeller, but this method is prone to the problem of residual film winding on the picking roller, which needs to be cleaned manually frequently, affecting the normal operation of the machine. SUMMARY

[0003] Therefore, in order to solve the technical problem of winding residual film on the picking roller of the existing residual film recycling machine and to separate the residual film from the picking roller, the present application provides a picking roller of a residual film recycling machine, which comprises a roller shaft, a plurality of film picking teeth arranged on the roller shaft, a plurality of edge plates fixedly connected to both ends of the roller shaft, a plurality of belt rollers arranged outside the roller shaft in a circumferential ring around the roller shaft, and a plurality of belts wrapped on the belt rollers.

[0004] To achieve the above purpose, the present application provides the following technical solutions:

[0005] A picking roller of a residual film recycling machine, comprising:

[0006] a roller shaft, on which a plurality of film picking teeth are arranged, and at both ends of which a plurality of edge plates are fixedly connected;

[0007] a plurality of belts for transmitting the residual film collected by the film picking teeth to a film separating device;

[0008] a plurality of belt rollers for supporting the belts and rotating with the belts;

[0009] a plurality of groups of belt rollers are arranged outside the roller shaft in a circumferential ring around the roller shaft with the roller shaft as the center, and the belts are wrapped on the belt rollers.

[0010] On the other hand, when a belt and a belt roller are used to separate the residual film, there will be friction between the belt and the belt roller, causing wear. In order to further reduce the wear caused by friction between the belt and the belt roller and increase the service life of the belt, preferably, the two ends of the belt roller are respectively rotatably connected to the side plates located at both ends of the drum shaft.

[0011] Preferably, the movement speed of the belt is different from the linear speed of the belt roller moving around the drum axis.

[0012] Preferably, a support plate is fixedly connected to the drum shaft;

[0013] One end of the belt roller shaft is rotatably connected to the side plate, and the other end is rotatably connected to the support plate.

[0014] Preferably, the two belt roller axes along the axial direction of the drum axis are not on the same straight line.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) The picking roller of the residual film recycling machine provided by the present invention is provided with a belt roller shaft which is circumferentially arranged outside the drum shaft with the drum shaft as the center, and the belt is wrapped around the belt roller shaft. The rotation of the drum shaft drives the side plate to rotate, and the belt roller shaft is used to support the belt and rotate with the belt. The belt is used to transfer the residual film to the film stripping device, and the residual film is separated by the belt, which can effectively prevent the residual film from being wrapped around the drum shaft.

[0017] 2) The picking roller of the residual film recycling machine provided by the present invention can rotate by itself when the linear speed of the belt is different from the linear speed of the belt roller on the picking roller rotating around the roller axis, thereby reducing the friction between the belt and the belt, reducing the frictional resistance, and also reducing the mutual wear between the belt and the belt roller, thereby increasing the service life of the belt. Further preferably, the linear speed of the belt is greater than the linear speed of the belt roller on the picking roller rotating around the roller axis. BRIEF DESCRIPTION OF THE DRAWINGS
