[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] This embodiment provides an automatic material screening belt feeder, combined with... Figure 1-2 As shown, the device includes a frame 10, a discharge chamber 11 inside the frame 10, a feeding belt 12 connected to the feeding chamber 11, an outlet of the feeding belt 12 connected to the inlet of a conveyor belt 13, a route alignment structure on the frame 10 above the conveyor belt 13, a waste pushing structure at the outlet of the conveyor belt 13, and a material collection structure connected to the outlet of the conveyor belt 13.

[0021] In this embodiment, the material is poured into the discharge chamber 11 and transported to the conveyor belt 13 via the feeding belt 12. As the conveyor belt 13 moves, the material gradually moves to the center line of the conveyor belt 13 under the pushing action of the route-organizing structure and is arranged in sequence. As the material continues to move forward, it moves to the waste pushing structure one by one. The waste discharge structure removes unqualified materials, and qualified materials continue to move to the material collection structure for collection or enter the next operating platform for further processing.
