Description

Technical Field

[0001] The utility model relates to the technical field of chutes, in particular to an automatic cleaning device for a port belt conveyor unloading chute. Background Art

[0002] A chute is a slot on the ground that is used to transport things from high to low. It has a smooth inner surface and things can slide down automatically (such as a ore flow chute for washing gold ore or an inclined water chute for flowing logs). It is mainly used in small open-pit mines. In large and medium-sized open-pit mines, the chute is often used in conjunction with the chute, which can be set up within the mining area or outside it. The port belt conveyor unloading chute is a common equipment for loading and unloading goods in ports and docks. It is usually located at the tail of the port belt conveyor and is used to smoothly unload the goods in the transportation process from the belt conveyor to the destination, such as a cargo ship or a yard.

[0003] In the bulk material conveying system of the port, the belt conveyor is a kind of transportation equipment for continuous conveying of bulk materials. When the water content of the transported bulk material is high, the inner wall of the chute where the belt conveyor head discharges the material is prone to compaction. As the operating cycle becomes longer, the internal compaction thickness becomes thicker, and the gradual narrowing of the interior of the chute will affect the material conveying capacity, and manual entry is required for cleaning. There are the following disadvantages: Due to the small internal space of the chute, only one person can enter with a pneumatic pick for cleaning operations, and a safety belt must be worn when working inside. There is a high safety risk when cleaning materials. Utility Model Content
