The feeding structure includes a rack, a hopper, a feeding chute, two pushing mechanisms, a pushing-up structure, a slide rail, an inlet frame, two closed slides, and four pulleys. The pushing rod is located between the two pulleys on the corresponding side. When the pushing rod moves up and down, it pushes the closed slides to move up and down. When the closed slides move up and down, they always close the left and right sides of the inlet frame.

When using a pump to suck the material through negative pressure, it is difficult for the sand to quickly enter the suction pipe. In order to overcome the suction resistance caused by the clumping of sand, the pump needs to generate greater negative pressure to suck in the sand, which means that the pump needs to consume more electrical energy, increasing the energy cost during production. Artificially assisted stirring is time-consuming, labor-intensive, and inefficient, which is not conducive to ensuring the efficiency of material supply.
