Description

Technical Field

[0001] The utility model relates to the technical field of ore screening equipment, in particular to a sand and gravel separator with convenient screen replacement. Background Art

[0002] In sand and gravel mining, the mined sand and gravel need to be screened, and for this purpose, a sand and gravel sorting machine is usually required. During operation, the sand and gravel collide with the screen body of the sorting machine, causing the screen body to wear quickly. Therefore, the screen body needs to be replaced frequently. However, in the existing structure, the screen body is usually fixed to the machine body by multiple screws and is tightened and fixed with the assistance of a pressure plate. Installation and disassembly are very difficult, and a lot of disassembly time is required. At the same time, it often requires multiple people to work together, which reduces the replacement efficiency and affects production. Utility Model Content
