[0012] The present application is a mechanical device specially used for loading fine particles or powdery materials, and is suitable for loading fine particles or powdery materials (such as river sand, rice, feed, etc.) into warehouses or cargo boxes for storage. When the loader is performing loading operations, the rotating conveyor belt drives the upper hopper on it to shovel the lower material into the hopper and then transport it to the rear and dump it into the cargo compartment, etc. The loading and transportation process can be carried out continuously, and the material is directly output from the rear of the conveyor belt without stopping in the middle.
