Detailed Description

In order to explain the technical content, the achieved objects and the effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings.

Example one

As shown in figure 1, the grass winding prevention device for the rotating part of the agricultural machine comprises a rotating part 1 and a static part 2, wherein the rotating part 1 is rotatably connected with the static part 2, when the grass winding prevention device works, the rotating part 1 rotates around a rotating central line of the rotating part, crop leaves or weeds can be wound at the connecting part of the rotating part 1 and the static part 2, and when too many crop leaves or weeds are wound, machine failure and fire accidents can be caused due to heat generation caused by friction. The device also comprises two static stoppers 3 and two movable stoppers 4 matched with the static stoppers 3, and in other embodiments, one or more static stoppers 3 or movable stoppers 4 can be arranged according to needs.

The static stopper 3 is fixedly arranged on the static component 2 along the circumferential direction of the rotating component 1;

the movable stopper 4 is fixedly arranged on the rotating component 1 along the circumferential direction of the rotating component 1;

the movable stopper 4 is disposed inside the static stopper 3, that is, the distance between one side of the movable stopper 4 facing the rotation center line of the rotating member 1 and the rotation center line of the rotating member 1 is smaller than the distance between one side of the static stopper 3 facing the rotation center line of the rotating member 1 and the rotation center line of the rotating member 1. In another embodiment, the movable stopper 4 may be disposed outside the stationary stopper 3, that is, the distance between the side of the movable stopper 4 facing the rotation center line of the rotating member 1 and the rotation center line of the rotating member 1 is greater than the distance between the side of the stationary stopper 3 facing the rotation center line of the rotating member 1 and the rotation center line of the rotating member 1.

The working principle of the device is as follows:

when the agricultural machine is working normally, the rotating part 1 rotates around its own rotation central axis, assuming a forward rotation, when there is crop leaves or weeds wound around the joint of the rotating part 1 and the stationary part 2, most of them will be blocked and scraped by the stationary stopper 3. When leaves or weeds are wound on the movable stop block 4 or the static stop block 3, the movable stop block 4 rotates along with the rotating component 1, the rotating movable stop block 4 and the static stop block 3 can generate a shearing effect, and the wound leaves or weeds are sheared. The amount of the wound object entering the joint of the rotating member 1 and the stationary member 2 along the gap between the dynamic stopper 4 and the static stopper 3 is prevented by controlling the distance between the opposite sides of the dynamic stopper 4 and the static stopper 3 in the radial direction of the rotating member 1. When the agricultural machine stops working, the rotating component 1 can be driven to rotate reversely, leaves or weeds which are wound at the joint of the rotating component 1 and the static component 2 can be loosened firstly, and then the wound leaves or weeds are pulled tightly and scraped due to the rotating motion of the movable block 4 relative to the static block 3, so that the purpose of removing the wound leaves or weeds is achieved.

In conclusion, the device has a simple structure, does not influence the normal work of the machine, and only needs to increase the stop blocks on the static part and the rotating part, so that the problems of leaf winding and grass winding at the dynamic and static combination part of the rotating part and the static part of the agricultural machine are solved with smaller cost and space. The machine fault and fire accident caused by excessive friction heat generation due to the winding of weeds and leaves are avoided, the time for cleaning the wound crop leaves and weeds when the machine is stopped is shortened, the abrasion of parts is reduced, and the service life of the parts is prolonged. For the blade structure, the dog structure is radial along rotary part 1, has bigger thickness, so under the same material condition, has better rigidity, warp in avoiding the use, also avoids artifical ann to tear down machinery time because of colliding the blade injured simultaneously.

Preferably, the outer side of the movable stop block 4 and the inner side of the static stop block 3 are provided with matched concave-convex structures which are in non-contact embedding. In this embodiment, the outer side of the movable stopper 4 and the inner side of the static stopper 3 are of a step structure which is matched with each other, and in other embodiments, the movable stopper may be of a concave-convex structure which is matched with each other, such as a curved surface, as shown in fig. 2. Thus, when the movable stop 4 rotates along with the rotating component 1, a material clamping gap 5 is formed between the outer side of the movable stop 4 and the inner side of the static stop 3, the material clamping gap 5 is a zigzag channel along the axial section of the rotating component 1, so that crop leaves or weeds can be prevented from entering the joint of the rotating component 1 and the static stop 2 along the gap between the movable stop 4 and the static stop 3, and the grass winding prevention effect is further improved. In other embodiments, when the movable stopper 4 is disposed on the outer side of the static stopper 3, the inner side of the movable stopper 4 and the outer side of the static stopper 3 are provided with matching concave-convex structures, and the concave-convex structures are in non-contact engagement.

Preferably, the two sides of the static stopper 3 along the axial direction of the rotating component 1 are arranged in a sawtooth shape, when the rotating component 1 rotates around the self rotating central axis, the effect that the static stopper 3 scrapes leaves or weeds wound at the joint of the rotating component 1 and the static component 2 is further enhanced. In other embodiments, the movable stoppers 4 may be arranged in a zigzag shape along both axial sides of the rotating member 1, so that the shearing effect between the movable stopper 4 and the stationary stopper 3 can be improved, and the grass-tangling prevention effect can be improved.

Although the utility model has been described in detail above with reference to specific embodiments, it will be apparent to one skilled in the art that modifications or improvements may be made based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
