Description

Technical Field

[0001] The utility model belongs to the technical field of mining, and relates to a splash-proof device for discharging waste rock on the vibrating screen. Background Art

[0002] After the heavy magnetic tailings are screened by a vibrating screen, the materials under the screen enter the subsequent separation process, and the waste rock on the screen is transported to the waste rock yard by a belt conveyor. When the waste rock on the screen is discharged onto the belt, the waste rock will splash onto the ground near the belt, causing the ground to be slippery, and people are prone to fall when walking nearby, which has potential safety hazards. Moreover, it will increase the labor intensity of workers to maintain the site hygiene, and the improper impact of the waste rock on the belt causes the belt to easily deviate. When the amount of waste rock is large, these phenomena will be aggravated.

[0003] After arranging two baffles between the tail of the vibrating screen and the belt, there will still be a small amount of stones splashing onto the ground near the belt, and the impact points of the waste rock on the belt are not concentrated, which will still cause the belt to deviate. After installing the baffles, the daily maintenance of the vibrating screen and the belt, as well as the disassembly and replacement of the baffles, are inconvenient.

[0004] In view of the above problems, the common method is to arrange two baffles between the tail of the vibrating screen and the belt to slow down the splashing of stones; the on-site workers regularly adjust the belt to prevent deviation and regularly clean the ground to maintain hygiene.
