The utility model provides a seal structure has solved the technical problem that the material infiltration and destroy the bearing among the annular scraper conveyor transported substance material process.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a sealing structure comprises a shell, a rotating shaft, a bearing and a bearing seat, wherein the rotating shaft is connected with the bearing seat through the bearing; the pressing seal is connected with the rotating shaft in an interference fit mode, and the pressing seal is fixedly connected with the shell; a V seal is sleeved on the rotating shaft above the compression seal; the lip of the V seal is in contact with the top surface of the compression seal.
Further, the compression seal and the shell are fixedly connected through bolts.
Further, a framework oil seal is installed on the bearing seat. The function of ensuring that the lubricating grease in the bearing is stored in the bearing seat is achieved.
Further, the framework oil seal is reversely arranged on the bearing seat, and an auxiliary lip of the framework oil seal faces the bearing.
Furthermore, an annular groove is formed in the top surface of the bearing seat and located below the compression seal, and the framework oil seal is installed in the annular groove.
Further, a seal is formed between the compression seal and the framework oil seal.
The utility model discloses the beneficial effect who reaches:
a V seal is sleeved on the rotating shaft above the compression seal; the lip of the V seal is abutted against the top surface of the compression seal. The V seals are fixed on the shaft head through elastic deformation, the lip of the V seal is in contact with the compression seal, and the lip of the V seal is elastic and can be always attached to the compression seal, so that the situation that materials cannot enter the butt joint of the compression seal and the rotating shaft from the position is ensured. The sealing performance of the bearing is guaranteed, and the bearing is prevented from being damaged.
Furthermore, the compression seal is fixed on the shell through a bolt, and the compression seal is in interference fit with the rotating shaft, so that the material cannot fall down from a gap between the compression seal and the rotating shaft. The framework oil seal adopts reverse installation: the lip is outward, the vice lip is towards the bearing, and when adding lubricating grease in the bearing housing, unnecessary lubricating grease can extrude from vice lip, forms a set of sealed in the cavity between pressure seal and skeleton oil blanket. The multiple sealing design strengthens the sealing performance of the bearing, and more effectively avoids the damage to the bearing caused by the material infiltration in the process of conveying the material by the annular scraper conveyor.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 and 2, the sealing structure comprises a housing 4, a rotating shaft 3, a bearing 5 and a bearing seat 6, wherein the rotating shaft 3 is rotatably connected with the bearing seat 6 through the bearing 5. The bearing seat 6 comprises a horizontal seat and a vertical seat vertically extending downwards from the horizontal seat, and the vertical seat is connected with the rotating shaft 3 through a bearing 5. The top surface of the horizontal seat is fixedly connected with the shell 4. The compression seal 7 is connected with the rotating shaft 3 in an interference fit mode, and the compression seal 7 is fixedly connected with the shell 4. The rotating shaft 3 above the compression seal 7 is sleeved with a V seal 8, the rotating shaft 3 is a stepped shaft, the rotating shaft 3 above the compression seal 7 is provided with a convex section, and the V seal 8 is arranged between the convex section and the top surface of the compression seal 7; the lip of the V-seal 8 abuts the top surface of the pinch seal 7. In this embodiment, the V seal 8 is a V-shaped seal ring, the V seal 8 is fixed to the shaft head of the rotating shaft 3 through elastic deformation, and a lip of the V seal 8 contacts the pressing seal 7. Because the lip mouth of V seals 8 is flexible, can always paste with compressing tightly sealed 7 together, guaranteed that the material can not enter compressing tightly sealed 7 and the butt joint department of pivot 3.
