Description

Technical Field

[0001] The utility model relates to the technical field of cotton pickers, in particular to a film-winding prevention mechanism for a packing bin of a cotton picker. Background Art

[0002] my country's cotton planting area is quite extensive. In the past, cotton picking mainly relied on manual labor, which was labor-intensive and inefficient. With the continuous improvement of my country's agricultural mechanization level, the development of large-scale machine-picking cotton has become the general trend of my country's cotton industry, so cotton pickers have appeared on the market. By using cotton pickers, the speed of cotton picking can be effectively increased, creating higher income for cotton pickers. The main structure of the cotton picker includes a frame, a picking head, a cotton collecting bin and a baling bin. When in use, the picking head collects cotton, and the collected cotton will be transported to the cotton collecting bin, and then the cotton will be sent to the baling bin by the cotton conveying belt, in which the cotton is packed into rolls by baling film, and the initial state of the baling film is a film roll. As the baling proceeds, the film roll rotates, the baling film is pulled out from the film roll, and is sent to the baling position by the belt on the film conveying rack. The film output speed and the film delivery speed are theoretically the same, but in practice, in order to prevent the baling film from being deformed or broken, some more will be produced when the film is output to ensure that there is a margin of baling film. However, when there is too much margin or the baling film on the film conveying rack is not used in time, the baling film at the inlet of the film conveying rack will accumulate and roll back onto the film output roller, affecting the normal use of the film. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a film-winding prevention mechanism for a baling bin of a cotton picker, which can effectively prevent the baling film at the film outlet roller of the baling bin from rolling back.

[0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is as follows: a film-winding prevention mechanism for the baling bin of a cotton picker, comprising a film-discharging roller and an anti-rewinding plate, the anti-rewinding plate being provided with a connecting portion and a film-blocking portion, the film-discharging roller being provided with a plate body embedding groove, the connecting portion comprising a plurality of connecting teeth, and the connecting teeth being embedded in the plate body embedding groove.

[0005] In the above technical solution, the depth of the plate body embedded in the groove is consistent with the thickness of the connecting part.

[0006] In the above technical solution, the thickness of the connecting portion is 3 to 5 mm.

[0007] In the above technical solution, both ends of the anti-rewind plate are fixedly connected to the bin body on the corresponding side.

[0008] In the above technical solution, the end of the connecting tooth is provided with an arc segment which fits with the surface of the film discharge roller.

[0009] In the above technical solution, reinforcing ribs are provided between the connecting portion and the barrier film portion.

[0010] To sum up, the technical solution of the utility model has the following beneficial effects compared with the traditional technical means: the utility model adds an anti-rewinding plate to the film feed roller, and the connecting part of the anti-rewinding plate is inserted into the plate body embedding groove of the film outlet roller, so that the anti-rewinding plate can fit the film feed roller, and the outer diameter at the film outlet roller is consistent with the film outlet roller, which does not affect the normal delivery of the packaging film, and this connection method will not have gaps, preventing extremely thin packaging film from getting stuck, and at the same time the film blocking part blocks the film to prevent the film from rolling back.
