A seed cotton film removal machine

Abstract

The invention relates to the technical field of cotton processing, in particular to a seed cotton residual film removing machine. The seed cotton residual film removing machine comprises an air floating part, a removing part arranged above the air floating part and a box body used for connecting the air floating part with the removing part; the box body is provided with a cotton inlet and a cottonoutlet; the air floating part comprises a plurality of air supply assemblies arranged in parallel, each air supply assembly comprises an air supply pipeline and an air storage cavity communicated with the air supply pipeline and provided with an exhaust end, the exhaust end of each air storage cavity comprises a plurality of exhaust holes, the exhaust holes are obliquely formed so that air flow exhausted from the exhaust holes can flow obliquely upwards, and the air speeds of the air flow introduced into every two adjacent air supply pipelines are different; the removing part comprises a plurality of removing assemblies which are located in the box body and sequentially arrayed in the direction from the cotton inlet to the cotton outlet. Residual film is fully exposed on the surface layerof seed cotton through the air flow flowing obliquely upwards and removed by the removing part accordingly, seed cotton fibers are not damaged through the mode of removing the residual film, and thequality of ginned cotton is high.

Description

technical field [0001] The invention relates to the technical field of cotton processing, in particular to a seed cotton residual film removing machine. Background technique [0002] Xinjiang is the main cotton planting area in my country. The total cotton output in Xinjiang accounts for more than 50% of the total output of the country and 1 / 6 of the total output of the world. The frost-free period in this area is short, and the annual rainfall is below 200 mm. The wide-film cotton planting technology is widely used. The film-laying rate of cotton fields is almost 100%, and 60,000 to 80,000 tons of broken film are newly produced every year. Due to the lack of labor, the planting area of ​​machine-picked cotton in Xinjiang continues to expand, and mechanized harvesting results in a large amount of residual film in the seed cotton, which seriously affects the quality of the seed cotton. At present, it is difficult to remove the residual film on the lint processing line. Durin...
