[0035] The reset mechanism 1 218 includes a hinge rod 1 2181, and the end of the hinge rod 1 2181 near the limiting plate 1 212 is hinged to the outer wall of the limiting plate 1 212 through a hinge block, the bottom of the outer wall of the hinge rod 1 2181 is slidably connected to the inner wall of the limiting sleeve 2183, the bottom of the inner wall of the limiting sleeve 2183 is slidably connected to the top of the outer wall of the hinge rod 2185, and the end of the hinge rod 2185 near the limiting plate 213 is hinged to the limiting plate 213 through a hinge block.

Too much material is accumulated, resulting in incomplete combustion. At the same time, the clean products push the limiting plate 212 to swing on the outer wall of the swing plate 211. At the same time, the swing plate 211 swings on the top of the support seat 201. The clean products push the limiting plate 212 to open the limiting plate 212, so that the fixed rod 214 on the top of the limiting plate 212 drives the sliding rod 216 to compress the spring 3 219 to slide on the inner wall of the limiting sleeve 217. The swing plate 211 swings and drives the limiting mechanism 22 to limit the swing plate 211. At the same time, the swing plate 211 drives the limiting plate 212 to swing regularly along the surface of the conveyor belt 205, so that the clean products are distributed in a curved shape on the surface of the conveyor belt 205, so that the clean products can be fully burned and dust can be reduced.
