Background
The cotton planting range of China is quite wide, the cotton picking in the past mainly depends on manual picking, the labor intensity is high, and the efficiency is low. With the development of agricultural machinery, cotton pickers gradually become popular, and the cotton picker can effectively improve the speed of manual cotton picking, so as to create income for cotton pickers.
The cotton picker usually runs in an environment with poor road conditions, the requirements on the walking speed and the power are high, the work done by an engine is decelerated and torque-increased by a main speed reducer by a rear drive axle (rear axle), then is transmitted to a differential mechanism, is redistributed to a left half shaft and a right half shaft, and finally is transmitted to a drive axle, so that a motor vehicle runs. That is, the rear axle bears the weight of the vehicle body and also bears the functions of changing the power transmission direction, reducing the rotating speed, increasing the torque, differentiating between wheels and the like.
The rear axle transmission of the existing cotton picker usually adopts a traveling motor to drive a gear box with a large reduction ratio.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific preferred embodiments.
In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, "first", "second" and the like do not indicate the degree of importance of the component parts, and thus, are not to be construed as limiting the present invention. The specific dimensions used in the present embodiment are only for illustrating the technical solution, and do not limit the protection scope of the present invention.
As shown in fig. 1 and 2, in the prior art, a rear axle transmission mechanism generally adopts one-stage large reduction ratio transmission, an output shaft of a large displacement plunger motor is connected to an input shaft of a large reduction ratio reduction gearbox integrated on a rear axle, and output torque is increased through the reduction gearbox.
As shown in fig. 3, a rear axle transmission mechanism of a cotton picker comprises a first speed reducing part and a second speed reducing part; the first speed reduction part comprises a walking motor 1 and a speed reduction box 2, and an output shaft of the walking motor is connected with the speed reduction box; the second speed reduction part comprises a transmission part and a steering rear axle 5, and the steering rear axle is connected with the speed reduction box through a transmission mechanism. The total reduction ratio by adopting two-stage reduction exceeds the transmission ratio of the common rear axle on the market.
The transmission part comprises a transmission shaft 3 and a universal joint, the universal joint is arranged at the connecting part of the transmission shaft 3 and the reduction gearbox 2 and the steering rear axle 5, the universal joint comprises a first universal joint 4 and a second universal joint 6, the first universal joint 4 is arranged between the reduction gearbox 2 and the transmission shaft 3, and the second universal joint 5 is arranged between the other end of the transmission shaft 3 and the steering rear axle 5.
