Description

Water steady mixing station stirring main shaft protection device Technical field: The utility model relates to the technical field of stirring spindles, in particular to a stirring spindle protection device of a water-stable mixing station. The background technology is as follows: The mud stabilized macadam is widely used for highways, airports, wharfs, parking lots and the like, and becomes an indispensable important material in highway construction and has large dosage. Therefore, the water-stable mixing station plays a critical role in construction production, and each key part is optimized and improved to bring infinite profit space to the whole project. In the stirring process, the batching machine sends the required aggregate into the half cylinder according to the weighing by using the conveyer belt, and the main shaft of the stirring cylinder is continuously added with water for rotary stirring to form the water stable stirring material. When the base material freely falls into the mixing cylinder, the main shaft continuously rotates, so that friction between the base material and the main shaft of the mixing cylinder is generated. Because the mixing volume is large, the main shaft of the mixing cylinder is broken by long-time friction. The utility model comprises the following steps: Therefore, the utility model provides a stirring main shaft protection device of a water-stable stirring station, which is used for overcoming the problems in the prior art. The utility model is implemented by the following technical scheme: The utility model provides a steady mixing station stirring main shaft protection device of water, is including rotating the stirring main shaft that sets up in steady mixing station of water, is fixed with stirring vane on the stirring main shaft, stirring main shaft upper end is provided with protection component, protection component fixes on being close to the lateral wall of steady mixing station feed end of water, and protection component includes the guide plate of two slopes, and two guide plates become the welding of the style of calligraphy of falling V and cover stirring main shaft axial projection region, the guide plate surface is provided with the guide structure along the incline direction interval. Preferably, the flow guiding structure comprises a plurality of first flow guiding rods and second flow guiding rods, wherein the first flow guiding rods and the second flow guiding rods form a folded line type arrangement structure on the surface of the flow guiding plate, and the length L1 of the first flow guiding rods and the length L2 of the second flow guiding rods meet the relation of W/2< L1< W and W/2< L2< W, wherein W is the width of the flow guiding plate. Preferably, the extending direction of the first guide bar and the second guide bar forms an included angle of 30-60 degrees with the inclined direction of the guide plate 5. Preferably, the cross sections of the first guide rod and the second guide rod are semicircular structures, and the convex surfaces of the first guide rod and the second guide rod face to the feeding direction. Preferably, the spacing distance between the adjacent first guide bar and the adjacent second guide bar is 1/5-1/3 of the width of the guide plate. The utility model has the advantages that the vertical falling material flow is guided to two sides through the inverted V-shaped guide plate structure, so that the material slides along the inclined direction of the guide plates, the axial impact force is effectively converted into the transverse dispersion force, the direct impact load born by the main shaft is reduced, meanwhile, the two guide plates are welded to form the inverted V-shaped structure, the axial projection area of the stirring main shaft is completely covered, and a continuous protective barrier is constructed above the feeding end, so that the material is prevented from directly striking the surface of the main shaft.
