Description

Technical Field

[0001] The utility model relates to the technical field of ore screening, in particular to an automatic ore dressing device for mining. Background Art

[0002] Ore is a non-renewable resource for traditional Chinese medicine and one of the energy sources for human daily life. As human beings become more and more dependent on energy, they need to continuously mine energy. Mining is a complex industrial process, in which the separation and screening of ore is an important link. Since the block sizes of ore are different, it is necessary to use mineral processing equipment for screening.

[0003] The existing mineral processing device separates ores of different sizes by an inclined screen. The screened ore slides down the slope of the screen, and the screened ore moves downward to another screen for further screening. For example, the patent number CN216728134U discloses an efficient and energy-saving mineral processing device for mining. The patent screens and separates the ore by inclined screens distributed up and down, and transmits it separately by a transmission belt. However, the mass of the ore is usually large, and the ore between the screens falls freely, which will impact the screen, easily expand the aperture of the screen, and reduce the service life of the screen. The ore that is easy to fall freely is easy to splash and cause injuries to people, affecting the actual use effect. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can effectively make the ore screened by the upper screen slide into the buffer box by arranging the guide plate, buffer box, buffer plate, chute, slider, slide rod, damping block and spring, and use the buffer plate and damping block to buffer the ore to prevent the ore from falling directly onto the surface of the lower screen, thereby solving the problem that the screen is easily damaged by the impact of falling ore, and also preventing the ore from falling directly and causing splashing and injuring people. The buffer box is further used to make the ore slide smoothly onto the lower screen and slide down the conveyor belt along the lower screen, so that the screening of the surface of the lower screen can be more uniform, and the situation that the center and edge of the screen are damaged due to the pressure difference caused by the direct fall of the ore can be avoided.
