Description

Technical Field

[0001] The utility model relates to the field of material feeding devices, and more specifically, to a material lifting device. Background Art

[0002] A material hoist is a device used to lift materials on an inclined path. Unlike vertical hoists (such as elevators), this type of hoist transports materials from a lower position to a higher position along an inclined track or conveyor belt. It is widely used in a variety of industries, including mines, ports, construction sites, and grain processing.

[0003] When a material lifting device is used to transport powdered materials, residual material on the conveyor belt surface is difficult to remove in a timely manner. The residual powder accumulates on the conveyor belt surface for a long time, absorbing moisture from the air and creating a humid environment. This environment is conducive to the growth and reproduction of microorganisms, which is particularly suitable for material lifting devices in the pharmaceutical and food industries. The growth of microorganisms may contaminate subsequent conveyed materials and pose a threat to human health. Utility Model Content
