[0002] The cotton planting range in China is quite extensive, and the cotton picking mainly relies on manpower before, which has high 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 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 two-row machine and four-row machine, and the two-row cotton picker is more suitable for small-scale farms or complex terrain areas because it usually has better maneuverability and flexibility. The two-row 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-row cotton picker has higher operation efficiency and is suitable for large-scale cotton planting areas. For example, the four-row cotton picker produced by Tiejian Heavy Industry can pick 500 mu per day, which is equivalent to the work of 2000 cotton pickers 。

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

[0006] The front axle structure of the existing cotton picker is shown in Figure 1 、 2 , which includes a walking gearbox arranged in the middle of the front axle frame and two edge wheel reduction boxes at both ends of the front axle frame. The walking gearbox drives the edge wheel reduction boxes to drive the front wheels to rotate. However, this transmission structure is very complex, occupies a large space of the vehicle, greatly increases the load of the vehicle, and greatly reduces the control precision and output torque of the vehicle. SUMMARY

[0007] In view of the above problems, the utility model aims to provide a two-row cotton picker with a wheel edge drive mechanism, which optimizes the space of the frame of the cotton picker, facilitates installation and maintenance, and improves the control precision and output torque of the cotton picker.

[0009] The utility model provides a two -row cotton picker with wheel edge drive mechanism, has the frame, is equipped with the cotton collecting bin on the frame, is equipped with the picking head frame on the front end of frame, is equipped with two picking heads on the picking head frame, two picking heads on the picking head frame are opposite arrangement, picking head links with the cotton collecting bin, is equipped with wheel edge drive mechanism in the wheel inboard of frame, wheel edge drive mechanism is hydraulic motor, hydraulic motor can drive wheel rotation.

[0010] In the above technical scheme, the front axle frame of the frame is provided with a front wheel set at both ends, the inside of the front wheel hub of the front wheel set is provided with a mounting flange, and the hydraulic motor is mounted on the mounting flange.

[0011] In the above technical scheme, the front axle frame of the frame is provided with a motor mounting plate at both ends, and the hydraulic motor is arranged on the motor mounting plate and in transmission connection with the front wheel hub.

[0012] In the above technical scheme, the hydraulic motor is a wheel edge integrated motor.

[0013] In the above technical scheme, the output torque of the hydraulic motor is 14000N*m.

[0014] In the above technical scheme, the width of the cotton collecting bin is 3200mm, and the width of the frame is 1300mm.

[0015] In the above technical scheme, the two picking heads on the picking head frame are arranged in opposite directions.

[0016] In the above technical scheme, the side of the cotton collecting bin is provided with a cotton unloading door.

[0017] In summary, the technical scheme of the utility model has the beneficial effects compared with the traditional technical means: the utility model changes the front axle structure of the traditional cotton picker driven by the reduction gearbox to rotate the hub, directly controls the rotation of the front wheel hub through the integrated hydraulic motor, does not need the transmission of components such as reduction gearbox and connecting rod, reduces the mass of the power system, improves the transmission efficiency, cancels the mechanical differential device, is conducive to reducing the transmission noise, is conducive to the optimization of the overall layout of the vehicle, is more convenient to install and maintain, the two hydraulic motors do not have a linkage relationship, are controlled respectively through the control mechanism, the control precision is higher, and the output torque is larger.
