[0014] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0015] See Figure 1 and Figure 2 This utility model provides a single-lever control mechanism for walking and steering with dual pumps and dual motors, including a control lever 1. The lower ends of the control lever 1 are respectively connected to a left steering lever 2 and a right steering lever 3, and the left steering lever 2 is located to the left of the right steering lever 3. The lower end of the left steering lever 2 is connected to a left rotating arm 4, and the lower end of the right steering lever 3 is connected to a right rotating arm 5. The right rotating arm 5 is sleeved on the left rotating arm 4. The back of the right rotating arm 5 is connected to a left lifting rod 6, and the lower end of the left lifting rod 6 is connected to a left swing arm 8. The right end of the left rotating arm 4 is connected to a right lifting rod 7, and the lower end of the right lifting rod 7 is connected to a right swing arm 9. The left swing arm 8 and the right swing arm 9 are used to connect two hydraulic pumps of the harvester. By swinging in different directions, the hydraulic flow direction is changed, thereby changing the speed and direction of the motor, thus realizing walking and steering.

[0016] A crossbar is welded and fixed to the lower end of the control lever 1, and the left and right ends of the crossbar are rotatably connected to the left steering lever 2 and the right steering lever 3, respectively.

[0017] The right rotating arm 5 has a round hole, and the right rotating arm 5 is fitted onto the left rotating arm 4 through the round hole.

[0018] The left steering rod 2 and the left swing arm 4 are rotatably connected by a pivot shaft. The left swing arm 4 and the right lifting rod 7 are rotatably connected by a pivot shaft. The right lifting rod 7 and the right swing arm 9 are rotatably connected by a pivot shaft. The right steering rod 3 and the right swing arm 5 are rotatably connected by a pivot shaft. The right swing arm 5 and the left lifting rod 6 are rotatably connected by a pivot shaft. The left lifting rod 6 and the left swing arm 8 are rotatably connected by a pivot shaft.

[0019] In use, when the control lever 1 is pushed forward, the left steering lever 2 and the right steering lever 3 are pressed backward, the left rotating arm 4 and the right rotating arm 5 rotate counterclockwise backward, and at the same time the left lifting lever 6 and the right lifting lever 7 are lifted, which drives the left swing arm 8 and the right swing arm 9 to rotate clockwise upward at the same time, driving the pump and motor, and the whole machine moves forward.

[0020] When the control lever 1 is turned to the left, the left steering lever 2 moves backward and the right steering lever 3 moves forward, causing the left rotating arm 4 to rotate counterclockwise backward and the right rotating arm 5 to rotate clockwise forward. At the same time, the left lifting lever 6 is lifted upward and the right lifting lever 7 is pressed downward, causing the left swing arm 8 to rotate clockwise upward and the right swing arm 9 to rotate counterclockwise downward, driving the pump and motor, and the whole machine to rotate to the left.

[0021] When the control lever 1 is turned to the right, the left steering lever 2 moves forward and the right steering lever 3 moves backward, causing the left rotating arm 4 to rotate clockwise forward and the right rotating arm 5 to rotate counterclockwise backward. At the same time, the left lifting lever 6 is pressed down and the right lifting lever 7 is lifted up, causing the left swing arm 8 to rotate counterclockwise downward and the right swing arm 9 to rotate clockwise upward, driving the pump and motor, and the whole machine to rotate to the right;

[0022] When the control lever 1 is pulled back, the left steering lever 2 and the right steering lever 3 are pulled forward, the left rotating arm 4 and the right rotating arm 5 rotate forward clockwise, and at the same time the left lifting lever 6 and the right lifting lever 7 are pressed down, causing the left swing arm 8 and the right swing arm 9 to rotate downward counterclockwise, driving the pump and motor, and the whole machine moves backward.

Various modifications and variations can be made to this application by those skilled in the art.
