Description

Technical Field

[0001] The utility model relates to the technical field of material guiding devices, in particular to an anti-blocking structure for a funnel at the head of a belt conveyor. Background Art

[0002] The conveying equipment in the port area is a belt conveyor. The funnel space at the head of the belt conveyor is not large, so it is easy to cause blockage in the head funnel when loading and unloading sticky materials. Funnel blockage is a major problem of the current belt transportation system, which affects operating efficiency and increases operating risks.

[0003] The head hopper currently on the market can control the discharge speed by adjusting the opening angle of the switch door at the material outlet. When the funnel is blocked, the angle is increased to increase the material outlet, which is convenient for moving a large amount of material downward to dredge and prevent blockage. However, the material has a large impact force on the switch door. When the maximum discharge angle is adjusted for dredging and anti-blocking, the material unloading speed is accelerated and the impact force becomes greater, which will cause serious damage to the switch door and affect subsequent use. Secondly, large objects cannot be dredged only by dredging and anti-blocking, which will cause large materials to be blocked in the funnel and cause abnormal use. Therefore, it is necessary to improve an anti-blocking structure for the head hopper of a belt conveyor to solve the above problems. Utility Model Content
