Obviously, the accompanying drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other embodiments can also be obtained.

[0037] See Figure 1 and Figure 2 As shown, this embodiment provides a control mechanism, including an operating rod 1, a rotating plate 3, a first pin shaft 7, a support plate 6, a first switch 4, and a second switch 5. The rotating plate 3 is connected to the operating rod 1 and can rotate with the operating rod 1. The rotating plate 3 includes a rotating hole in the middle of the rotating plate 3, a first touch key 301 on the rotating plate 3, and a second touch key 302 on the rotating plate 3. The rotating hole A1 is sleeved on the first pin shaft 7 and rotates around the first pin shaft 7. The support plate 6 is sleeved on one end of the first pin shaft 7 and is arranged adjacent to the rotating plate 3. The first switch 4 is placed on the support plate 6 and one end thereof contacts the first touch key 301 to start the starting gear of the agricultural operation machine. The second switch 5 is placed on the support plate 6 and one end thereof contacts the second touch key 302 to start the reverse gear. When the first switch 4 contacts the first touch key 301, the second switch 5 does not contact the second touch key 302. When the second switch 5 contacts the second touch key 302, the first switch 4 does not contact the first touch key 301. Through this solution, it can better match the user's usage habits. And when the rotating plate 3 is not in the vertical position (such as in the forward or reverse state), the first switch 4 does not contact the first touch key 301, and the agricultural operation machine cannot be started, avoiding direct starting during the running state, improving the safety problems easily caused by improper operation, and improving the safety and convenience of users during agricultural operations.

[0038] The control mechanism of the agricultural operation machine provided in this embodiment further includes a compression spring 10 sleeved on the first pin shaft 7 and located on the right side of the rotating plate 3, a locking nut 11 sleeved on the other end of the first pin shaft 7, and a gasket sleeved on the first pin shaft 7. The gasket 8 at least includes a first gasket 801 and a second gasket 802 that contact the rotating plate 3. The controllability of the control mechanism is enhanced.

[0039] The rotating plate 3 further includes a second connecting portion 305 disposed below the first connecting portion 304.

[0040] The control mechanism of the agricultural operation machine provided in this embodiment further includes a connecting rod 9. The connecting rod 9 includes a joint rod 901 connected to the second connecting portion 305 through a third pin shaft 15, and a long rod 902 disposed below the joint rod 901 and connected to the joint rod 901 by a threaded nut 11.

[0041] See Figure 3 As shown, with the forward direction of the operation machine as the front, the rotating plate 3 is provided with a first connecting portion 304 on the right side surface of the rotating plate 3; the operating rod 1 includes an operating portion 101 and a short connecting portion 102. The short connecting portion 102 is disposed within the first connecting portion 304. The second pin 13 connects the first connecting portion 304 and the first connecting portion 304 through a second pin shaft 12 and a pin 13. Specifically, both ends of the first connecting portion 304 have through holes. The short connecting portion 102 is disposed within the first connecting portion 304. The second pin shaft 12 has a limiting hole. One end of the second pin shaft 12 with the limiting hole sequentially passes through the through hole at one end of the first connecting portion 304, the short connecting portion 102, and the through hole at the other end of the first connecting portion 304 and then extends out. The pin 13 penetrates into the limiting hole of the second pin shaft 12, thereby connecting the operating rod 1 to the first connecting portion 304. When the operating rod 1 is pulled backward, it drives the rotating plate 3 to rotate backward around the first pin shaft 7 by a certain angle; when the operating rod 1 is pushed forward, it drives the rotating plate 3 to rotate forward around the first pin shaft 7 by a certain angle.

[0042] The limiting spring 2 is disposed within the first connecting portion 304 and sleeved on the relatively rear end position of the short connecting portion 102. One end of the limiting spring 2 abuts against the operating portion 101 and the other end abuts against the inside of the first connecting portion 304. This helps to better assist the operating rod 1 to achieve reset after reversing.

[0043] See Figures 4 to 6As shown, the first switch 4 includes a button S, a switch pin shaft S1 in contact with the button S, a first steel ball 401 in contact with the first contact key 301, and a bushing S2 sleeved on the switch pin shaft S1 and the first steel ball 401; the second switch 5 includes a button S, a switch pin shaft S1 in contact with the button S, a second steel ball 501 in contact with the second contact key 302, and a bushing S2 sleeved on the switch pin shaft S1 and the second steel ball 501; the rotating plate 3 further includes a transition portion 303 arranged in the vertical direction and connected to the second contact key 302. The first contact key 301 has a cylindrical surface in contact with the first steel ball 401, and the second contact key 302 has a flat surface in contact with the second steel ball 501. When starting, the rotating plate 3 is placed vertically (refer to Figure 5 ), at this time, the first steel ball 401 is in contact with the first contact key 301, and the second steel ball 501 is in contact with the transition portion 303 to achieve startup (it should be noted that after the agricultural operation machine starts, when performing forward or backward operations, the operating lever 1 drives the rotating plate 3 to rotate, and the agricultural operation machine remains in the startup state and will not stall due to the first steel ball 401 not being in contact with the first contact key 301. However, before starting, if it is in the forward or reverse state, the agricultural operation machine cannot be started because the first steel ball 401 is not in contact with the first contact key 301); when reverse is needed, the rotating plate 3 is driven by the operating lever 1 to rotate backward by a certain angle around the first pin shaft 7, and the first steel ball 401 gradually separates from the first contact key 301. Since the rotating plate 3 rotates, the second steel ball 501 slides relative to the transition portion 303 towards the flat surface of the second contact key 302 to start reversing.

[0044] The contact surface area of the second contact key 302 is larger than that of the first contact key 301, and the second switch 5 does not coincide with the center projection plane of the rotating hole A1. Through this design, the larger contact area can make the reverse switch easier to contact the contact key, improving the convenience of user operation. For the short contact key with a short contact surface, when in the forward or reverse gear position, the rotating plate 3 is not in the vertical position. At this time, the first contact key 301 will not contact the first switch 4. Through this solution, it can better match the user's usage habits, and when the rotating plate 3 is not in the vertical position (such as in the forward or reverse state), the first switch 4 does not contact the first contact key 301, avoiding direct startup in the traveling state (such as in the forward or reverse gear state), improving the safety problems that are prone to occur due to improper operation, and increasing the safety and convenience of users during agricultural operations, enhancing the safety of user use.

[0045] See Figure 7As shown, the connection hole B1 of the support plate 6 is sleeved on the first pin shaft 7. A support seat portion 604 is provided on one side of the support plate 6 away from the rotating plate 3. The support seat portion 604 includes a first through hole C1 and a second through hole C2. First switch holes D1 and second switch holes D2 are provided at positions on the support plate 6 corresponding to the first through hole C1 and the second through hole C2. The first switch 4 passes through the first through hole C1 and the first switch hole D1, and the second switch 5 passes through the second through hole C2 and the second switch hole D2. It is better for placing the first switch 4 and the second switch 5, increasing the stability of the first switch 4 and the second switch 5.

[0046] The support plate 6 further includes a first bending portion 601, a second bending portion 602, and a third bending portion 603. The first bending portion 601 and the third bending portion 603 are respectively placed at the upper edge and the lower edge of the support plate 6 and their bending directions are opposite. The second bending portion 602 is placed in the middle of the support plate 6. A first contact portion is formed between the second bending portion 602 and the third bending portion 603. Both the first switch hole D1 and the second switch hole D2 are placed on the first contact portion.

[0047] The rotary tiller control mechanism of this solution further includes an electric control wire 14 placed in the operating rod 1 for realizing the operation of the handle button S above the operating rod 1.

[0048] Another aspect of this embodiment further provides an agricultural working machine including the control mechanism of the above solution.

[0049] A control mechanism provided by the present utility model includes an operating rod 1, a rotating plate 3, a first pin shaft 7, a support plate 6, a first switch 4, and a second switch 5. By controlling the operating rod 1, when shifting gears and starting, the first switch 4 and the second switch 5 respectively contact the first contact key 301 and the second contact key 302 to realize the reverse and start operations. Through this solution, it can better match the user's usage habits, and when the rotating plate 3 is not in the vertical position (such as in the forward or reverse state), the first switch 4 does not contact the first contact key 301, improving the safety problems that are prone to occur due to improper operation and enhancing the safety and convenience of users during agricultural operations.

[0050] It is obvious to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present utility model without departing from the spirit and scope of the present utility model. Therefore, it is intended that the present utility model cover modifications and variations of the present utility model that fall within the scope of the appended claims and their equivalent technical solutions.
