[0002] The blanking chute is a device for guiding and conveying bulk materials (such as ores, coal, grain, chemical raw materials, etc.) in industrial production, and is usually installed at the discharge port of equipment (such as a crusher, a screening machine, a conveyor) or a material transfer point, so as to guide the materials from a high place to a low place through gravity or auxiliary power, and ensure controllable material flow and reduce the impact on the equipment.

[0003] In the semi-mobile crushing open-pit coal mining process, after the heavy mining truck throws the stripped large raw coal into the large material bin of the crushing station, the raw coal is conveyed to the crushing cavity above the crusher by the heavy and light plate conveyors, and then is conveyed to the next process by the belt conveyor through the discharge chute. The height difference is nearly 7 meters, the conveying direction of the heavy material is perpendicular to the conveying direction of the belt conveyor, the bulk material is about 0.3m (three-dimensional size), the material throughput is greater than or equal to 3000 tons per hour, and it belongs to a continuous heavy load impact working condition, which can cause the belt of the belt conveyor and the buffer device to be damaged and unable to be used, and seriously affect the production plan and increase the maintenance and operation cost.
