Description

Technical Field

[0001] The utility model relates to the technical field of cement transportation, in particular to a leakage-proof trough conveyor. Background Art

[0002] The trough conveyor used in the cement transportation process moves from the tail to the head under the traction of the rotating sprocket at the head through the chain. After bypassing the head, it turns to the tail, and then bypasses the tail sprocket to turn to the head, forming a closed and continuously running conveying loop; when loading, the hopper of the conveyor moves to the bottom of the unloading structure of the silo, and the material falls freely into the hopper of the conveyor. Since there is a certain distance between the upper port of the hopper and the bottom of the unloading structure, the material often leaks on both sides of the hopper when falling, and a lot of dust is generated, which seriously pollutes the surrounding environment.
