[0002] Cotton cultivation is widespread in my country. Previously, cotton harvesting relied mainly on manual labor, which was labor-intensive and inefficient. With the continuous improvement of agricultural mechanization in my country, large-scale mechanized cotton harvesting has become an inevitable trend in the cotton industry, leading to the emergence of cotton harvesters on the market. Using cotton harvesters can effectively increase harvesting speed and generate higher incomes for cotton harvesters. The main structure of a cotton harvester includes a frame, a harvesting head, a collection bin, and a baling bin. During operation, the harvesting head collects cotton, which is then transported to the collection bin and finally to the baling bin for packing.

[0003] In existing technology, cotton harvesters need to use fans to suck up cotton from the harvesting head and transport it to the cotton box. Generally, one fan drives two to three harvesting heads, and each fan is driven by an independent hydraulic motor. However, the working environment of the cotton harvester is a cotton field, and there will be a lot of cotton stalks and dust on the frame. In order to keep the frame clean and prevent debris from entering the cotton box and packing box, a special cleaning fan is also installed on the frame to periodically blow air onto the frame to clean the upper part of the frame. However, this structure is too cumbersome and takes up more space. Utility Model Content

[0010] In the above technical solution, the air vent on the cleaning head is a flat opening and is horizontally set on the upper surface of the vehicle frame.

[0011] In the above technical solution, the front end of the vehicle frame is provided with six cotton picking heads, the fan assembly includes three fans, two of which are connected in series and connected to two cotton picking heads through the cotton picking interface of the diversion pipe. The diversion pipe of the independent fan is provided with a cotton picking interface and a cleaning interface.
