Residual film picking roller with film picking teeth

Abstract

The invention discloses a residual film picking roller with film picking teeth. The residual film picking roller comprises a cam disc fixedly installed on a roller shaft, film picking tooth beams parallel to the roller shaft are evenly distributed on the periphery of the cam disc, the film picking teeth on the film picking tooth beams are matched with through holes in the wall of the roller, the film picking tooth beams are fixedly connected with inflection points of crank throw arms, rolling rings arranged on the end portions of short arms of the crank throw arms are matched with grooves in the cam disc, the end portions of long arms of the crank throw arms are hinged to an axial framework of the roller, roller wall radial supporting frames are evenly distributed in the roller, a rolling ring replacement window is formed in the bottom face of the cam disc, connecting lugs are arranged on the upper portions of threads of tooth handles of the film picking teeth, connecting holes are formed in the connecting lugs, locknuts are installed on the tooth handles, extending out of installation holes in the film picking tooth beams, of the film picking teeth of the film picking tooth beams, and the film picking teeth are fixedly connected to the film picking tooth beams by the connecting lugs through screws. The residual film picking roller is reasonable in structure, safe and reliable in performance, good in stability of operation, high in recycling rate of residual films and convenient to maintain, and the use cost can be reduced.

Description

technical field [0001] The invention relates to agricultural machinery, which belongs to farmland residual film recovery machinery, in particular to a residual film picking roller with film picking teeth. Background technique [0002] Plastic film is one of the important material materials for agricultural production. The application of plastic film mulching technology has greatly promoted the improvement of agricultural output and benefits, and led to the change of agricultural production methods and the rapid development of agricultural productivity. However, with the application of plastic film and the use of With the continuous increase of the number of years, the white pollution caused by a large amount of residual film has also seriously affected the progress of agricultural production. The harm is manifested in: Although the residual film is very thin, it takes hundreds of years to completely degrade under natural conditions, which will lead to changes in the physical...

AI Technical Summary

Problems solved by technology

[0003] At present, there is still a kind of residual film recovery drum with the following disadvantages: 1. The ribs of the drum only increase the rigidity of the axial direction of the drum, but the radial rigidity of the drum is not enough, and radial deformation is prone to occur; 2. The design of the swing arm is poor in manufacturability , cannot be formed at one time and welding is difficult, which increases the cost of the machine tool; 3. The rollers that match the cam disc are not easy to disassemble after wear and maintenance is inconvenient; Unreliable, which poses a threat to the safety of the entire drum; 5. The film picking teeth are easily damaged and have a short service life
