[0119] Embodiment 10

[0120] On the basis of the above-mentioned embodiments, this embodiment further provides an agricultural machine, which includes the above-mentioned gear shifting control controller.

[0121] The scheme provides a new type of agricultural machinery, the agricultural machinery simple structure, reasonable in design, shift is shift handle 1 always only need to move in front and back longitudinal plane, small space, shift when the operator's arm does not need to extend to the left or right, convenient operation, more easily force.

[0122] The working principle of the present application is as follows:

[0123] When shifting, when the shift handle 1 is in the vertical state and the upper shift joint 2 and the lower shift joint 3 are in the middle position, at this time, it is in neutral position, and the shift handle 1 is moved upward to the two clamping columns 8 respectively clamped into the two clamping grooves 7 on the upper shift joint 2 under the elastic force of the spring 10, at this time, the limiting piece 9 abuts against the shaft 6 to limit the upward movement of the shift handle 1, and at this time, the spring 10 is in the compressed state;

[0124] Then, manually rotating the shift handle 1 forward or backward can drive the upper shift joint 2 to rotate, at this time, the switching of the second gear and the third gear can be realized;

[0125] Finally, the shift handle 1 can be manually moved downward to clamp the two clamping columns 8 thereon into the two clamping grooves 7 on the lower shift joint 3, and the shift handle 1 is rotated forward or backward to drive the lower shift joint 3 to rotate in the front and back directions, at this time, the switching of the first gear and the reverse gear can be realized, and at this time, the spring 10 is in a further compressed state, and the shift handle 1 cannot be moved upward due to the blocking of the upper shift joint 2, which is simple and convenient to operate, time-saving and labor-saving.

[0126] The specific structure of the shift control controller in the prior art is described in detail in Figure 8 , the path of the shift handle 1 is obviously different from the present application, and the space occupied is large.

[0127] For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0128] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.

[0129] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
