The side of the roller 221 facing away from the baffle 101 abuts against the guide rail, and the shape of the guide rail is adapted to the transmission chain 220. The guide rail is connected to the inner side wall of the casing 100, so that the transmission chain 220 can move stably under the limiting action of the guide rail and the baffle 101, thereby ensuring the stable operation of the filtering mechanism 200. It can be understood that the transmission gear 230 made of polyformaldehyde meshes with the roller 221 made of nylon, so that the sensitivity of the drive and transmission structure to sand and gravel in the water is reduced. Compared with metal mechanisms, it is more wear-resistant and less prone to jamming. The sealing plate 213 and the baffle 101 made of non-metallic and non-rubber materials have good processability and high processing precision, which is more conducive to improving the sealing effect, and are smooth and quiet during movement. The combination of the sealing plate 213 and the baffle 101 can prevent the residue in the water inlet chamber from leaking out from the side of the filter mechanism 200, resulting in residue leakage, which reduces the filtration efficiency of the screen machine and has a negative impact on the transmission chain 220. The sealing plate 213 and the baffle 101 improve the durability and filtration effect of the internal inlet screen machine.
