When the stirring wheel assembly needs to be taken out, it can be taken out from the protective cover composed of the bottom plate and the top plate by pulling outward along the stirring shaft limiting groove, which is very convenient to use.

[0006] Preferably, the bolt assembly comprises a bolt, a first nut, a second nut and a third nut, wherein the bolt penetrates the corresponding threaded holes of the bottom plate and the top plate from bottom to top, the bolt is fixed with the bottom plate by the first nut after penetrating the bottom plate, and the bolt is fixed with the top plate by the second nut and the third nut after penetrating the top plate, so that the fixing structure between the bottom plate and the top plate is stable.

[0007] Preferably, the bottom plate and the top plate are both wooden plates, which are light in weight, strong in rigidity and good in protection effect.

[0008] Preferably, the bottom plate and the top plate have the same area and are both larger than the area of the stirring wheel, so that the stirring wheel and the claws can be completely covered.

[0009] Preferably, the width of the stirring shaft limiting groove is 1.1-1.3 times of the diameter of the stirring shaft, so that the stirring shaft can be steadily fixed and prevented from shaking in the stirring shaft limiting groove, and the stirring shaft can be conveniently moved in the stirring shaft limiting groove.

[0010] The stirring wheel protection device has the advantages that the device is simple in structure, reasonable in design and convenient to use, and can realize good protection of the stirring wheel. BRIEF DESCRIPTION OF DRAWINGS

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by the ordinary people in the art without creative labor are within the protection scope of the utility model.

[0018] Embodiment: a stirring wheel protection device.

[0019] Referring to Figures 1 to 5 As shown in the figure, a stirring wheel protection device comprises a bottom plate 1, a top plate 2 and a bolt assembly 3. The bottom plate 1 and the top plate 2 are arranged in parallel and spaced apart from each other. A cavity between the bottom plate 1 and the top plate 2 forms a protection space for the stirring wheel 200 and the claw 300 installed on the stirring wheel 200. Three threaded holes 5 corresponding to each other in up-down direction are arranged on the bottom plate 1 and the top plate 2. The bottom plate 1 and the top plate 2 are connected through the bolt assembly 3 installed in the three threaded holes 5 corresponding to each other in up-down direction. The bolt assembly 3 comprises a bolt 31, a first nut 32, a second nut 33 and a third nut 34. The bolt 31 penetrates the threaded holes 5 corresponding to each other in up-down direction on the bottom plate 1 and the top plate 2 from bottom to top. The bolt 31 is fixed with the bottom plate 1 through the first nut 32 after penetrating the bottom plate 1. The bolt 31 is fixed with the top plate 2 through the second nut 33 and the third nut 34 after penetrating the top plate 2. The above fixing structure can ensure the stability of the fixing structure between the bottom plate 1 and the top plate 2. The front end of the top plate 2 is provided with a stirring shaft limiting groove 4 corresponding to the stirring shaft 100. The stirring shaft limiting groove 4 is used for limiting the movement of the stirring shaft 100. The width of the stirring shaft limiting groove 4 is 1.2 times the diameter of the stirring shaft 100. The stirring shaft limiting groove 4 can not only stably fix the stirring shaft 100 and prevent the stirring shaft 100 from shaking in the stirring shaft limiting groove 4, but also facilitate the movement of the stirring shaft 100 in the stirring shaft limiting groove 4.

[0020] In the embodiment, the bottom plate 1 and the top plate 2 are both wooden plates. The wooden plates are light in weight, strong in rigidity and good in protection effect. The area of the bottom plate 1 is the same as that of the top plate 2, and both are larger than the area of the stirring wheel 200, so that the stirring wheel 200 and the claw 300 can be completely covered.

[0021] The stirring wheel protection device has simple structure, reasonable design and convenient use, and can realize good protection of the stirring wheel assembly. In actual work, only the stirring shaft 100 in the stirring wheel assembly is aligned with the stirring shaft limiting groove 4 corresponding to the stirring shaft 100 at the front end of the top plate 2, and then is pushed inward along the stirring shaft limiting groove 4, the stirring wheel assembly can be pushed into the protection cover composed of the bottom plate 1 and the top plate 2, and the protection of the stirring wheel 200 and the claw tooth 300 on the stirring wheel 200 can be realized. When the stirring wheel assembly needs to be taken out, only the stirring wheel assembly can be taken out from the protection cover composed of the bottom plate 1 and the top plate 2 by pulling outward along the stirring shaft limiting groove 4, the operation is simple and smooth, and the surrounding is firmly protected and isolated from danger.
