Description

Technical Field

[0001] The present invention relates to the technical field of material distribution funnels, and more specifically, to a lateral material distribution funnel and a material distribution method thereof. Background Art

[0002] Due to the advantages of belt conveyor systems in terms of transportation cost and transportation capacity, they have been widely used in large domestic open-pit metal mines and coal mines. In particular, their technical advantages have been demonstrated in the technical transformation of large deep-dip open-pit mines. Belt conveyors have the advantages of large production capacity, strong uphill capacity, short transportation distance, and low transportation cost. Currently, belt conveyors are used for development in some large open-pit iron ore mines. Many belt conveyor systems for comprehensive utilization of surrounding rock are parallel systems, and the material switching of the system is regulated by a flap valve placed in the diversion funnel. However, during system switching, the flap often fails to move or cannot reach the proper position due to material jamming, and operators need to enter the funnel to manually clear the material. This not only poses a great safety hazard but also results in high labor intensity, low efficiency, and the inability to fully utilize the system's efficiency. In some systems with high requirements for continuous operation, longitudinal diversion plates are usually used to divert materials, but it is difficult to control the diversion ratio, and online precise regulation cannot be achieved.

A distributor is arranged on each side of the material distribution funnel to meet different production mode combinations, realizing flexible production combination of the system. During the material distribution process, real-time feedback from a belt scale can be combined to achieve online precise lateral material diversion.
