[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] like Figures 1 to 6As shown, an embodiment of the utility model provides a manipulation mechanism, which is used to manipulate the lifter 50. The manipulation mechanism includes: a driving member 10, a transmission rod group 20 and a manipulation structure. The driving member 10 is rotatably arranged; one end of the transmission rod group 20 is hinged to the driving member 10, and the other end of the transmission rod group 20 is hinged to the fixed base, and the driving member 10 drives the transmission rod group 20 to move. The manipulation structure includes a first manipulation part 31 and a second manipulation part 32 that cooperate with each other. The first manipulation part 31 is arranged on the transmission rod group 20, and the first manipulation part 31 is protruding from the transmission rod group 20; the second manipulation part 32 is rotatably arranged on the fixed base, and the second manipulation part 32 is connected to the valve core rod. The first manipulation part 31 is located at the side of the second manipulation part 32, and the first manipulation part 31 and the second manipulation part 32 are at least partially arranged opposite to each other, so that the first manipulation part 31 pushes the valve core rod to move in a preset direction through the second manipulation part 32.

[0036] The operating mechanism provided in this embodiment can ensure the stability and flexibility of transmission by setting the transmission rod group 20. In addition, by setting the corresponding first operating part 31 and the second operating part 32, it can ensure that the valve core rod is stably pushed to move in the preset direction, thereby effectively ensuring the flexibility of operation. Compared with the flexible shaft structure, it is more flexible and reliable.

[0037] Specifically, the second operating part 32 has an arc-shaped side edge 321, and the arc-shaped side edge 321 is adapted to the motion trajectory of the first operating part 31, so that the second operating part 32 is pushed to rotate by the abutment between the side edges of the first operating part 31 and the second operating part 32. With such a structural setting, the adaptability of the first operating part 31 and the second operating part 32 can be better facilitated, so that the first operating part 31 can smoothly drive the second operating part 32 to move.

[0038] In this embodiment, at least part of the first operating part 31 and the second operating part 32 are arranged at intervals along the protruding direction of the first operating part 31, and at least part of the second operating part 32 is arranged alternately with the transmission rod group 20. With such a structural arrangement, it is convenient to effectively ensure that the first operating part 31 and the second operating part 32 can always be in stable contact, so that the two can move in coordination.

[0039] Specifically, the first operating portion 31 is an operating protrusion, which has a simple structure and is easy to manufacture.

[0040] In this embodiment, the second operating portion 32 is an operating plate to facilitate stable operating cooperation.

[0041] Specifically, the transmission rod group 20 includes a first transmission member 21 and a second transmission member 22, one end of the first transmission member 21 is hinged to the driving member 10. The second transmission member 22 is located below the first transmission member 21, one end of the second transmission member 22 is hinged to the other end of the first transmission member 21, and the other end of the second transmission member 22 is hinged to the fixed base, the first operating part 31 is arranged on the second transmission member 22, the second operating part 32 and the second transmission member 22 are arranged at intervals along the protruding direction of the first operating part 31, and at least part of the second operating part 32 is staggered with the second transmission member 22. In this way, stable transmission cooperation is facilitated.

[0042] In this embodiment, the transmission rod assembly 20 further includes a third transmission member 23, the two ends of which are respectively hinged to the first transmission member 21 and the second transmission member 22, and at least a portion of the third transmission member 23 extends along a preset direction. In this way, it is convenient to make up for the interval between the first transmission member 21 and the second transmission member 22 in the preset direction, and to facilitate stable transmission.

[0043] Specifically, the third transmission member 23 in this embodiment is a bent plate structure, which includes a first plate 231, a second plate 232 and a third plate 233 connected in sequence, the first plate 231 and the second plate 232 are connected at a first preset angle, the second plate 232 and the third plate 233 are connected at a second preset angle, the first plate 231 is hinged to the first transmission member 21, the second plate 232 extends along a preset direction, and the third plate 233 is connected to the second transmission member 22. With such a structural setting, the structure is simple and stable connection is facilitated.

[0044] In this embodiment, the driving member 10 includes a first driving rod 11 and a second driving rod 12 connected to each other, the first driving rod 11 and the second driving rod 12 are connected at a preset angle, one end of the first driving rod 11 away from the connecting portion of the first driving rod 11 and the second driving rod 12 forms an operating section, and one end of the second driving rod 12 away from the connecting portion of the first driving rod 11 and the second driving rod 12 is connected to the transmission rod group 20. With such a structural arrangement, it is convenient to optimize the structure of the driving member 10 and facilitate stable driving.

[0045] Specifically, the connection portion of the first driving rod 11 and the second driving rod 12 is rotatably arranged on the fixed seat, and the operating mechanism further includes a wear-resistant member 40, which is arranged between the connection portion of the first driving rod 11 and the second driving rod 12 and the fixed seat. With such a structural arrangement, it is convenient to effectively reduce the friction loss caused by the rotation of the first driving rod 11 and the second driving rod 12.

[0046] Specifically, the control mechanism provided in this embodiment is used, and the specific control principle of the control mechanism on the lifter 50 is as follows:

[0047] like Figure 4 As shown, the lifter 50 is in a descending state: when the first drive rod 11 rotates counterclockwise, the first drive rod 11 moves downward, and drives the third transmission member 23 to rotate counterclockwise and move downward through the first transmission member 21 (the first transmission member 21 can be a pull rod), and the third transmission member 23 drives the second transmission member 22 (the second transmission member 22 can be an operating panel) of the lifter 50 to move downward as well, and at this time the lifter 50 descends.

[0048] like Figure 5 As shown, the lifter 50 is in an ascending state: when the first driving rod 11 rotates counterclockwise, the first driving rod 11 pushes the first transmission member 21 to move downward, and the first transmission member 21 drives the second transmission member 22 and the second operating part 32 to rotate downward around the rotation point. While the second operating part 32 rotates, it drives the valve core rod of the multi-way valve to retract inward. Through this operation, the oil outlet direction of the multi-way valve can be controlled.

[0049] Specifically, the second operating portion 32 may be a connecting plate.

[0050] A second embodiment of the present utility model provides a tractor, which includes the control mechanism provided by the first embodiment.
