Description

Dustproof idler of conveyer Technical Field The utility model relates to the technical field of dustproof carrier rollers, in particular to a dustproof carrier roller of a conveyor. Background The dustproof carrier roller of the conveyor is an important component used in a conveyor belt system, and mainly aims to support the conveyor belt and reduce friction between the conveyor belt and a supporting roller, and meanwhile, external dust or other particles are prevented from entering the carrier roller through dustproof design, so that the efficiency and the service life of the conveyor are improved. The existing dustproof carrier roller of the conveyor is generally sleeved in the carrier roller shaft by a sealing cover in the use process, the sealing cover is fixed or embedded into two ends of the carrier roller to achieve a dustproof function, and the sealing cover is used for preventing external dust, sundries and the like from entering the carrier roller, ensuring the lubrication effect of the carrier roller in operation and prolonging the service life of the carrier roller. However, this design at present has a drawback of lacking a convenient quick-release structure, which means that when the seal cover needs to be replaced, an operator must manually detach the seal cover, and usually needs to use a tool to pry open the seal cover on the carrier roller, which is time-consuming and labor-consuming, and is complex to operate, increasing the workload of maintenance personnel, and also resulting in an increase in downtime of the apparatus. Disclosure of utility model The utility model aims to solve the problem that the prior art lacks a convenient quick-dismantling structure, which means that when the sealing cover needs to be replaced, an operator needs to manually dismantle the sealing cover on the carrier roller, and usually needs to use a tool to pry the sealing cover on the carrier roller, and the process is too time-consuming and labor-consuming. In order to achieve the aim, the dustproof carrier roller of the conveyor adopts the following technical scheme that the dustproof carrier roller of the conveyor comprises a carrier roller shaft, bearings are arranged on two sides of the outer surface of the carrier roller shaft, carrier roller bodies are arranged on the outer surfaces of the two bearings, sealing covers are movably sleeved on two sides of the carrier roller shaft, the two sealing covers are movably embedded in the carrier roller body, two connecting columns are fixedly arranged on one side, opposite to the two sealing covers, of the two connecting columns, the four connecting columns are movably embedded in the carrier roller body, a plurality of latch grooves are formed in the carrier roller body, and quick-release assemblies are arranged in the four connecting columns.
