Unginned cotton airflow tearing thinning device

Abstract

The invention relates to the technical field of cotton processing, in particular to an unginned cotton airflow tearing thinning device. The unginned cotton airflow tearing thinning device provided bythe invention comprises a plurality of air supply assemblies arranged in parallel; each air supply assembly comprises an air supply pipeline and an air storage cavity; each air storage cavity is provided with an air inlet end and an air outlet end; the air storage cavities communicate with air supply pipelines through the air inlet ends; the air outlet end of each air storage cavity is provided with a plurality of exhaust holes; and the exhaust holes are formed obliquely so that airflows exhausted through the exhaust holes can upwards flow obliquely, wherein the air speeds of the airflows pumped into every two adjacent air supply pipelines are different. Unginned cotton is torn and thinned through the airflows upwards flowing obliquely at different air speeds, residue films are completelyexposed on the surface layer of the unginned cotton so as to be removed through the airflow conveniently, and unginned cotton fibers are not damaged; and particularly, the residue films are removed inthe unginned cotton, the situation that the residue films are broken into a huge amount of tiny fragments due to impact of mechanical parts in the subsequent cotton ginning process and cannot be removed is avoided, and the quality of ginned cotton can be ensured through the method that the residue films are removed from the unginned cotton.

Description

technical field [0001] The invention relates to the technical field of cotton processing, in particular to an airflow tearing device for seed cotton. 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. During g...

Problems solved by technology

[0004] The purpose of the present invention is to provide a seed cotton air-flow tearing device that is reasonably designed and can fully expose the residual film on the surface of the seed cotton to facilitate the removal of the residual film by airflow, so as to solve the problem of easy removal of residual film in existing mechanical methods. The problem of broken and damaged seed cotton fibers at the same time
