It should be noted that, the steering control of the front wheel 21 may be performed by rotating a steering wheel, driving the hydraulic steering gear via a driving shaft, supplying oil to the steering cylinder 23 according to the steering of the steering wheel, and the steering cylinder may perform steering control in the direction via a link mechanism connected to the steering cylinder. Meanwhile, the walking control of the sugarcane harvester can control the walking hydraulic pump 93 (preferably a variable pump) by a handle in the cab 11, the variable pump and a driving motor for driving walking form a closed hydraulic control loop, and the oil supply size and the output direction of the variable pump can be changed by controlling the control handle, so that the output steering and the rotating speed of the driving motor are controlled, and the walking control of the sugarcane harvester is achieved. In addition, the cab 11 can be hinged on the frame 10, and the cab can be turned 45 degrees through the hydraulic cylinder, so that the maintenance and repair of the sugarcane harvester are very convenient.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
