Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and in particular to a film removing tooth stripping mechanism on a residual film recovery machine for removing residual film on the film removing teeth. Background Art

[0002] An important part of the mechanized residual film recycling machine is the residual film picking mechanism. The residual film is picked up from the ground by the film-picking teeth of the residual film picking mechanism and then collected through a collection box. For example, the film-picking teeth are spring-tooth structures or columnar structures, that is, a spring tooth is fixed on the rod body, and the residual film is picked up by the spring teeth. After the residual film is picked up by the film-picking teeth, some of the residual film may not be able to naturally detach from the film-picking teeth, so a separate film-removing mechanism is required to remove the residual film from the film-picking teeth. At the same time, there are also disadvantages in picking up residual film with spring teeth. After the spring teeth are used for a period of time, the elasticity is weakened or the spring teeth are fatigued and broken, which will affect the effect of picking up residual film.

[0003] Therefore, a picking mechanism composed of high-strength film stripping teeth and a film stripping tooth stripping mechanism capable of stripping residual film on high-strength film stripping teeth are proposed.

[0065] The film stripping teeth (20) are rod-shaped bodies, and the rod-shaped film stripping teeth (20) can cooperate with the groove-shaped film stripping teeth to scrape off the residual film from the grooves of the groove-shaped film stripping teeth.

[0066] As an improvement, a stripping shaft fixing plate (16) is provided. The stripping shaft fixing plate (16) is connected and fixed to the guide plate (29) via a connecting shaft B (26). The stripping square shaft (18) is fixed to the stripping shaft fixing plate (16).

[0068] In actual use: the film-lifting tooth (11) moves to pick up the residual film. After picking up the residual film, the film-lifting tooth (11) moves in the opposite direction to the film-removing mechanism, and after contacting the film-removing tooth (20), the film-removing tooth (20) is pushed to move backward to form an extrusion pressure. Under the action of the up and down movement of the fixed column (13), the film-removing tooth (20) moves downward to remove the residual film on the film-lifting tooth (11).

[0069] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several changes and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
