TECHNICAL FIELD

[0001] The utility model relates to cotton picker technical field especially is four line cotton picker with wheel edge drive mechanism. BACKGROUND

[0002] The cotton planting range in China is quite extensive, and the cotton picking used to mainly rely on manpower, which is of great labor intensity and low efficiency. With the continuous improvement of agricultural mechanization level in China, developing large-scale machine picking cotton has become the general trend of China's cotton industry, so the cotton picker appears in the market. Through the use of cotton picker, the cotton picking speed can be effectively improved, and higher income is created for the cotton picker. The main structure of the cotton picker includes a frame, a picking head, a cotton collecting bin and a packing bin. The picking head collects cotton, the collected cotton is transported to the cotton collecting bin, and then the cotton is sent to the packing bin for packing,

[0003] The conventional cotton picker is divided into four-line machine and four-line machine, and the four-line cotton picker is more suitable for small-scale farms or complex terrain areas because they usually have better maneuverability and flexibility. The four-line cotton picker has been used for about 30 years, which shows that it has been verified and recognized in practical application.

[0004] In comparison, the four-line cotton picker has higher working efficiency and is suitable for large-scale cotton planting areas. For example, the four-line cotton picker produced by Tiejian Heavy Industry can pick 500 mu per day, which is equivalent to the work of 2000 cotton pickers.

[0005] Generally speaking, the cost of the four-line cotton picker will be higher than that of the four-line cotton picker because its structure is more complex and can handle more cotton rows at the same time. In addition, the maintenance and operation of the four-line cotton picker may also be relatively complex.
