[0070] Embodiment 10

[0071] On the basis of the above embodiments, this embodiment also provides a tractor, including the flip-type power take-off shaft protective cover as described above.

[0072] This embodiment also provides a tractor. This tractor has a simple structure and a reasonable design. The shield support plate 4 of the protective cover is fixed on the towing drawbar, and the cover plate can be turned up or closed. The full-stroke movement of the towing device can be realized without removing the power protective cover, effectively reducing the operation burden of the user, and greatly improving the safety.

[0073] The working principle of the present utility model is as follows:

[0074] The towing support frame 1 is connected to the rear axle housing of the tractor chassis, and the whole structure is installed on the chassis;

[0075] When the towing hook 5 moves upward on the towing rail 2, the power take-off protective cover has a tendency to rotate around the rotating bolt 7 under the action of the towing hook 5. At this time, under the action of the compression spring 11, the steel ball is pushed into the card slot around the rotating bolt 7 of the power take-off protective cover body, realizing the up-turn and automatic locking of the power take-off protective cover;

[0076] When the towing hook 5 moves downward on the towing slide rail 2, the effect of the power output protective cover on the towing hook 5 is eliminated. During the downward rotation around the rotating bolt 7, the edge of the card slot of the power output protective cover squeezes the steel ball, and the steel ball pushes the compression spring 11 to move. When the adjacent card slot rotates to the position where the steel ball is located, the steel ball re-enters the card slot of the power output protective cover under the action of the compression spring 11, realizing the reset and locking of the protective cover.

[0077] The advantages of the present utility model are as follows:

[0078] 1. For the traditional structure, it is necessary to remove the power output protective cover to realize the up and down movement of the towing device in the full stroke of the slide rail, which is time-consuming and laborious. Moreover, the power output without the protection of the protective cover also brings potential safety hazards. After using this structure, the full stroke movement of the towing device can be realized without removing the power protective cover, effectively reducing the operation burden of users and greatly improving safety.

[0079] 2. The present utility model realizes the automatic flipping and locking of the protective cover through the linkage mechanism of the protective cover - steel ball - spring, which is more reliable than the traditional rubber protective cover and is not easily damaged.

[0080] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model 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 utility model.
