[0002] As a general-purpose belt conveyor, the grain belt conveyor is improved from the fixed belt conveyor. It is mainly used in the process of grain production, processing and transportation. The specific specifications and models are selected according to the production site. Due to the limitation of the terrain, some grain depots need to connect multiple belt conveyors in series to realize the operation of grain in and out of the warehouse. The front end of the front belt conveyor is arranged with a conical receiving hopper to receive the incoming grain transported by the rear belt conveyor, so as to realize the forward transmission operation of the material between the two adjacent belt conveyors. The grain contains a large amount of impurities and dust. When the grain vibrates or there is a drop, a large amount of dust and light impurities will float and fly out.
