Abstract

The invention provides a chain wheel structure for a coal mine scraper conveyor, and relates to the technical field of chain equipment. A chain wheel structure for a coal mine scraper conveyor comprises a chain wheel body, teeth and a chain wheel hole, the multiple teeth are fixedly connected with the outer side wall of the chain wheel body and distributed in an annular array mode, the front side wall and the rear side wall of the chain wheel body are both fixedly connected with mounting rings, and the chain wheel hole is formed in the chain wheel body. The outer side wall of the mounting ring is fixedly connected with a plurality of negative pressure plates, the plurality of negative pressure plates are distributed in an annular array, and the inner side wall of the mounting ring is fixedly connected with a circle of sealing cotton. In the rotating process of the chain wheel, the chain wheel can drive the negative pressure plate on the outer surface of the mounting ring to rotate, impurities between teeth are taken away through generated negative pressure, the cleanliness of the chain wheel can be kept to a certain extent, the sealing cotton with the aperture smaller than that of a chain wheel hole by 1.5 cm can effectively prevent the impurities in the chain wheel hole from entering the chain wheel hole, and normal operation of the working state is kept.

Description

Technical Field

[0001] The present invention relates to the technical field of chain equipment, and particularly to a sprocket structure for a coal mine scraper conveyor. Background Art

[0002] A sprocket consists of a hub, a web, and teeth. The tooth profile design needs to be precisely matched with the chain rollers or chain plates. When the sprocket rotates, the rollers of the chain are embedded in the tooth grooves to form meshing, and power transmission is achieved through the alternating pushing and pulling between the chain links. This meshing method combines the high efficiency of gear transmission and the flexibility of belt transmission.

[0003] Traditional sprockets do not have a cleaning structure during use. Especially for sprockets used in special working scenarios, not only is the cleaning troublesome, but impurities are extremely likely to be stored inside the sprocket holes, affecting the working state. Summary of the Invention

[0004] (I) Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides a sprocket structure for a coal mine scraper conveyor, which solves the problem that traditional sprockets do not have a cleaning structure during use. Especially for sprockets used in special working scenarios, not only is the cleaning troublesome, but impurities are extremely likely to be stored inside the sprocket holes, affecting the working state.

[0005] (II) Technical Solutions To achieve the above objectives, the present invention is realized through the following technical solutions: A sprocket structure for a coal mine scraper conveyor includes a sprocket body, teeth, and sprocket holes. A plurality of the teeth are fixedly connected to the outer sidewall of the sprocket body, and the plurality of teeth are distributed in a circular array. Both the front and rear sidewalls of the sprocket body are fixedly connected with mounting rings. A plurality of negative pressure plates are fixedly connected to the outer sidewall of the mounting rings, and the plurality of negative pressure plates are distributed in a circular array. A ring of sealing cotton is fixedly connected to the inner sidewall of the mounting rings.

[0006] Preferably, the aperture of the sealing cotton is 1.5 cm smaller than the aperture of the sprocket holes.

[0007] Working Principle: During use, when the sprocket rotates, it will drive the negative pressure plates on the outer surface of the mounting rings to rotate, generating negative pressure to carry away the impurities between the teeth, which can maintain the cleanliness of the sprocket to a certain extent. And the sealing cotton with an aperture 1.5 cm smaller than the aperture of the sprocket holes can effectively prevent impurities inside the sprocket holes from entering, ensuring the normal progress of the working state.

[0008] (III) Beneficial Effects The present invention provides a sprocket structure for a coal mine scraper conveyor. It has the following beneficial effects: The sprocket structure for a coal mine scraper conveyor, during the rotation of the sprocket, will drive the negative pressure plates on the outer surface of the mounting ring to rotate, generating negative pressure to carry away the impurities between the teeth, which can maintain the cleanliness of the sprocket to a certain extent. Moreover, the sealing cotton with a hole diameter 1.5 cm smaller than that of the sprocket hole can effectively prevent impurities inside the sprocket hole from entering and keep the normal operation of the working state.
