Problems solved by technology

[0002] At present, the harvesting method of sugarcane is mainly manual, and the most primitive method is used to cut down and ship. The whole process is labor-intensive and inefficient.
The sugarcane harvesters used in a small amount are mainly rubber crawler type, which adopts a mature crawler chassis structure, which has the advantages of low center of gravity, low ground pressure, and good adhesion, but at the same time, it also has slow moving speed, difficult transition, and high cost. shortcoming
[0003] The prior art closest to the present invention is the patent (Patent No.: 201520462110.X) entitled "Sugarcane Harvester High Clearance Front Axle". The left and right steering wheels are linked. When the left and right steering wheels encounter different obstacles, the whole machine will tilt to one side. The disadvantages are that the steering angle is small, the controllability is poor, and the whole machine has poor passability when encountering different obstacles.

Embodiment 1

[0024] Such as Figure 1 to Figure 3 As shown, the left front wheel 1 and the right front wheel 11 are installed below the frame, and the left front wheel 1 and the right front wheel 11 have independent lift steering mechanisms respectively. The front wheels use radial tires, which have a low damage rate to sugarcane perennial roots and good passability. The rim and spokes are welded and connected, and the strength is reliable.

[0025] The structure of the lifting steering mechanism is that the front wheels are installed on the wheel shaft assembly, the wheel shaft assembly is connected to the lifting cylinder 3, and the lifting cylinder 3 can drive the front wheel to perform lifting movement, and a steering cylinder 7 is provided, and the steering cylinder 7 is hinged with the lifting cylinder 3. Steering oil cylinder 7 can drive front wheel to do steering motion through lifting oil cylinder 3, and said front wheel is left front wheel or right front wheel. Wheel axle assemb...

Embodiment 2

[0029] Such as Figure 4 , Figure 5 As shown, the left front wheel and the right front wheel are provided with a drive motor 10, and the power shaft of the drive motor 10 is connected to the wheel axle assembly, which can realize the switching between two-wheel drive and four-wheel drive, further ensure the power of the whole machine, and then improve The accessibility of the whole machine. The frame is provided with a flat plate, and the flat plate is provided with mounting holes for installing the wheel shaft assembly or the drive motor. All the other structures and working principles are the same as those in Embodiment 1.

Abstract

The invention relates to an independent lifting and steering front axle for agricultural machinery. The independent lifting and steering front axle for the agricultural machinery comprises a left front wheel and a right front wheel. The left front wheel and the right front wheel are arranged under a frame, and the left front wheel and the right front wheel are respectively provided with independent lifting and steering mechanisms. The structure of each lifting and steering mechanism is that the front wheel is installed on a wheel axle assembly, the wheel axle assembly is connected with a lifting cylinder, the lifting cylinder can drive the front wheel to do lifting movements, a steering cylinder is provided, the steering cylinder is hinged to the lifting cylinder, the steering cylinder candrive the front wheel to do steering movements through the lifting cylinder, and the front wheel is the left front wheel or the right front wheel. According to the invention, the left front wheel andthe right front wheel can be independently controlled, and the manipulation is strong, not only can the driving speed be improved, but also the stability and the whole machine traversability in the driving process of the whole machine are greatly improved.
