Description

Technical Field

[0001] The utility model relates to the technical field of ore conveying equipment, in particular to an ore conveying device with a protective structure for mining. Background Art

[0002] Ore conveyor belt is a kind of conveying equipment widely used in the mining industry, which is mainly used to transport ore from the mining site to the processing or storage area. The equipment usually consists of conveyor belt, drive device, roller, tensioning device and bracket;

[0003] Therefore, the ore conveyor belt has the advantages of large conveying capacity, high efficiency and stable operation. It is an indispensable and important equipment in the mining industry. For example, the Chinese utility model patent disclosed by publication number CN221317923U: A conveying device with a protective structure for ore mining, in which a group of dust hoods are installed on the upper surface of the shells on both sides of the conveyor, and filters are installed on the opposite sides of the two groups of dust hoods. Each group of dust hoods is connected to a group of dust collection components, and the terminals of the two groups of dust collection components are connected to the dust collection box. A group of baffles are hinged on the side of the upper surface of each group of dust hoods facing the conveyor. The baffles are erected on the dust hoods through locking components, which can achieve protection for large pieces of stone. Although the application is passed Setting a baffle can prevent the ore from falling to the outside of the conveyor when conveying the ore. However, when the ore is conveyed by the conveyor, the ore will be transferred to the conveyor through other conveying devices or unloading devices such as a hopper. Therefore, when the ore falls onto the conveyor belt in the conveyor, the ore falls from a higher place and the falling speed increases, thereby generating a greater impact force on the belt. This impact force may cause increased wear on the belt surface and may even cause cracks or damage inside the belt. At the same time, under the action of high impact force, the friction between the belt and the ore will also increase accordingly, thereby accelerating the wear rate of the belt. Long-term high-intensity wear will shorten the service life of the belt. Utility Model Content
