[0003]Due to the fixed size of the screen hole in the existing trommel screen, it is easy to cause materials with similar size to the screen hole to be blocked in the screen hole, resulting in other materials not being able to Throwing out from the sieve holes leads to a decrease in screening efficiency. In this case, the existing trommel screens can only manually deal with the blockages in the sieve holes. Time-consuming and labor-intensive, seriously affecting efficiency

Description
technical field [0001] The invention relates to a variable-diameter drum screen. Background technique [0002] The trommel screen is a device that screens materials by driving the screen cylinder to rotate. The screen cylinder is a cylindrical sieve with sieve holes evenly distributed on the surface. It can be thrown out of the hole to achieve screening and can be used in various industries. [0003] Due to the fixed size of the sieve hole in the existing trommel screen, it is easy to cause materials with similar size to the sieve hole to be blocked in the sieve hole, so that other materials cannot be thrown out from the sieve hole, which leads to a decrease in screening efficiency. When this happens, the existing trommel screens can only manually remove the blockages in the screen holes. Not only does it need to be shut down for processing, but it also needs to be cleaned manually, which is time-consuming and laborious, and seriously affects the efficiency. [0004] There...
