When the main clutch operating lever is in the card slot of the clamping plate, due to the action of the torsion spring body, the main clutch operating lever is in a non-working state of protection at this time. When the clamping plate is manually toggled to rotate the torsion spring body until the main clutch operating lever disengages from the card slot, the main clutch operating lever is pressed to the required position. At this time, the whole machine is in a working state. This mechanism can well meet the requirement of preventing the main clutch from being accidentally engaged due to non-human subjective factors, is simple to operate, and safety is guaranteed.

[0004] To achieve the above purpose, an anti-accidental engagement mechanism for the main clutch of a corn harvester is provided, including: a control box and a main clutch operating lever. A torsion spring assembly is arranged on the top of the control box. The torsion spring assembly includes a fixing plate, a screw, a torsion spring body, a clamping plate, a card slot, and a limit post. The top of the fixing plate is threadedly connected with a screw. The top of the fixing plate is rotatably connected with a torsion spring body. The top of the torsion spring body is fixedly connected with a clamping plate. A card slot is arranged on the clamping plate. The top of the fixing plate is fixedly connected with a limit post.

[0005] According to the anti-accidental engagement mechanism for the main clutch of a corn harvester, the main clutch operating lever is located in front of the control box and is rotatably arranged with the control box.

[0006] According to the anti-accidental engagement mechanism for the main clutch of a corn harvester, the main clutch operating lever is located on the left side of the clamping plate, and the card slot faces forward.

[0007] According to the anti-accidental engagement mechanism for the main clutch of a corn harvester, the fixing plate is fixedly connected with the top of the control box through a screw.

[0008] According to the anti-accidental engagement mechanism for the main clutch of a corn harvester, the limit post is located on the right side of the torsion spring body, and the screw is located behind the limit post.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: By setting a fixing plate, screws, a torsion spring body, a clamping plate, a clamping groove, a limiting post, a control box and a main clutch operating lever, when the main clutch operating lever is in the clamping groove of the clamping plate, due to the action of the torsion spring body, the main clutch operating lever is in the protection of the non-working state at this time. When the clamping plate is toggled by hand to rotate the torsion spring body until the main clutch operating lever disengages from the clamping groove, the main clutch operating lever is pressed to the required position, and the whole machine is in the working state at this time. This mechanism can well prevent the accidental engagement of the main clutch caused by non-subjective factors of people, is simple to operate, and the safety is guaranteed.

[0010] Additional aspects and advantages of the utility model will be given in part in the following description, and in part will become apparent from the following description, or be learned through the practice of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS
