Description

Technical Field

[0002] The utility model relates to an impurity removal device for a cotton picker, which is an important component specially designed for improving the quality of cotton harvesting, and is particularly a handheld and portable device, which can effectively remove impurities in cotton, thereby improving harvesting efficiency and cotton quality.

[0003] In the existing technology, firstly, the cotton in some devices cannot be effectively collected and transported, and needs to be collected manually, which greatly reduces work efficiency and may cause the cotton to be unnecessary squeezed and damaged during the collection process. There is no automated collection system, and the operator needs to stop frequently to collect the cotton, which increases labor intensity. Secondly, the cotton in some devices may retain large lumps, affecting the quality of subsequent processing. It is difficult to effectively separate light debris in the cotton, such as leaves, dust, etc. The cotton may remain in a tight state, which is not conducive to subsequent processing and use. The subsequent processing process may require more energy to process the cotton that has not been preliminarily treated. Finally, it is difficult for some devices to effectively remove larger impurities in the cotton. Unfiltered cotton may contain a large amount of impurities, resulting in unstable quality of the final product. Cotton containing a large amount of impurities will increase the burden on subsequent processing equipment and may cause equipment damage. Utility Model Content
