A tailings pond is a dangerous source of man-made debris flow with high potential energy and is at risk of dam collapse. Once an accident occurs, it is easy to cause serious accidents. A tailings pond is an indispensable facility for the production of a mine beneficiation plant, and sand is generally removed and processed through a sand removal device.

[0003] Chinese patent CN219475015U discloses a rock and soil exploration sand sampling device, which discloses a technical solution for convenient sand sampling, solving the problem that the existing sand sampling device can only perform sand sampling work vertically. When encountering some uneven rock and soil, the sand sampling device is inconvenient to work, and in the process of sand sampling, the sampled sand can only be discharged after the sand sampling work is completed, which affects the efficiency of rock and soil exploration work.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology.

However, the surface of the ring is provided with insertion holes at equal intervals. When adjusting it, it needs to be repeatedly disassembled and assembled, which reduces the use effect. Therefore, a mine tailings pond sand collection device is proposed to solve the above problems. Utility Model Content
