Description

Belt feeder cylinder sealing device Technical Field The utility model relates to the technical field of belt conveyor roller sealing tools, in particular to a belt conveyor roller sealing device. Background In industrial scenes such as mines, ports, power plants and the like where belt conveyors are used for conveying materials, a belt conveyor roller is used as a core transmission component, normal operation of the belt conveyor roller is critical to the whole conveying system, however, a traditional belt conveyor roller shield has obvious defects in terms of sealing performance, and production safety and equipment service life are seriously affected; The prior publication number is CN208413054U, the name is a sealing component for a belt conveyor roller, the sealing component comprises a bearing seat, a cylinder body and a roller shaft, the cylinder body is in contact with a belt of the belt conveyor, the cylinder body is fixedly connected with the roller shaft, the bearing seats are arranged on two sides of the roller shaft, and the bearing seats are arranged on a ground foundation and fixed by foundation bolts. According to the technical scheme, the bearing and the bearing seat are integrated, the bearing and the bearing seat are directly installed without heating, and a reliable sealing structure is adopted, so that moisture and dust can be prevented from entering, the service life of the bearing is effectively prolonged, and the safe running of the roller is effectively ensured; However, the belt conveyor roller is lack of an effective sealing design at the positions of an observation window, a coal cleaning opening and the like, the observation window and a shield window are simply fixed through bolts, a large gap exists, and in the operation process of the belt conveyor, a large amount of dust is wrapped and clamped by air flow generated by rotation of the roller and escapes from the gaps, and in the case of a coal mine underground belt conveyor, the dust concentration of the underground environment is high, the dust leakage of the traditional shield enables the dust concentration of an operation area to rise further and extremely fast, the dust leakage is far in a high-dust environment and is in a high-dust environment for a long time, so that the health of operators is seriously endangered, occupational diseases such as pneumoconiosis and the like are easily caused, and the fault frequency of electrical equipment is increased due to dust accumulation, so that the problems are solved. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a roller sealing device of a belt conveyor. In order to achieve the purpose, the belt conveyor roller sealing device comprises a shield, wherein a first hinge is fixedly connected to the shield, a window is formed in the shield, an observation window is fixedly connected to the other end of the first hinge through a bolt, the observation window is hinged to the window through the first hinge, a plate opening is formed in the bottom of the shield, a second hinge is fixedly connected to the inner wall of the shield, a coal cleaning plate is fixedly connected to the other end of the second hinge through a bolt, and the coal cleaning plate is hinged to the plate opening. Preferably, a window handle is fixedly connected to one side of the observation window, a second seal is attached to the peripheral side of the observation window, and a bump is fixedly connected to the top of the observation window. Preferably, a bayonet is fixedly connected to the top of the window, and the inner wall of the bayonet is clamped with the protruding block. Preferably, the first seal is attached to the periphery of the coal cleaning plate, a plate handle is welded to the bottom end of the coal cleaning plate, and two fixing plates are fixedly connected to the shield and the bottom of the coal cleaning plate respectively.
