Description

Technical Field

[0001] The utility model relates to the technical field of coal conveyors, in particular to a coal conveyor capable of preventing scratches from sharp blades. Background Art

[0002] A coal conveyor is a device for transporting coal. When the material enters the coal conveyor along the chute, there is a certain spatial drop, which causes the material on the belt to accumulate a certain potential energy and rush down, which can easily cause the belt to be scratched. Therefore, a coal conveyor that can prevent scratches from sharp blades is provided.

[0003] When the existing materials fall from the upper belt to the lower belt, they naturally generate a certain speed. If a sharp object is accidentally mixed in the material, due to inertia, when the sharp object contacts the belt, its lower part will directly penetrate the belt and get stuck on the roller, and its upper part will be blocked by the front edge of the chute, thus forming a sharp knife, which will cut the belt during the forward movement of the belt. There is no structure to increase the falling angle of the material, and the belt cannot be protected. In response to the above problems, an innovative design is made based on the original coal conveyor to prevent scratches by sharp blades. Utility Model Content
