Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a lightweight cotton picker body frame. Background Art

[0002] Cotton is cultivated over a wide range in my country. In the past, cotton picking mainly relied on manual labor, which was labor-intensive and inefficient. With the development of agricultural machinery, cotton pickers have become more and more popular. Cotton pickers can effectively increase the speed of cotton picking, reduce labor, and improve the efficiency of warping. Among them, the body frame serves as the main skeleton structure of the whole machine and can provide installation support for other components. The manufacturing process of the existing cotton picker body frame usually includes processing each component first, and then connecting these components together through welding and assembly.

[0003] For example, patent publication number CN215582640U discloses a cotton picker frame and a cotton picker. The frame is constructed by arranging a front axle assembly, an intermediate frame, and a rear axle assembly. The front axle assembly is connected to one end of the intermediate frame, and the rear axle assembly is connected to the other end of the intermediate frame. Furthermore, a lifting device is provided on the intermediate frame to lift and repair parts. This allows workers to use the lifting device to lift and remove parts when repairing or replacing heavy parts on the vehicle, thereby reducing the difficulty of handling parts and improving maintenance or replacement efficiency. Compared to the existing integrated frame, the front axle assembly, intermediate frame, and rear axle assembly are first processed separately and then assembled to form the frame. This effectively reduces the difficulty of manufacturing the frame and improves frame production efficiency. However, the frame includes a large number of connectors, lifting mechanisms, guide rails, and other structures, resulting in structural redundancy. This also leads to problems with existing frame structures, such as heavy weight and high cost.

[0004] Therefore, it is necessary to design a lightweight cotton picker body frame to solve the above problems. Utility Model Content
