one end of the blanking plate, which is far away from the conveying bin, is abutted against the sliding plate;
a material pushing column is arranged on the side wall of the conveying bin;
the material pushing column is abutted to the discharging plate and is suitable for pushing the discharging plate to rotate when the conveying assembly vibrates, so that the sliding plate is pushed to open the discharging hole of the leakage hopper.
9. The piezo-electric based screen material delivery apparatus of claim 8,
the connecting column comprises an elastic connecting rod and a return spring;
one end of the elastic connecting rod is fixedly arranged on the connecting frame, and the other end of the elastic connecting rod penetrates through the lower material plate after penetrating through the reset spring;
the blanking plate is suitable for extruding the reset spring after rotation, so that the blanking plate is reset through the reset spring and the reset torsion spring after the pushing column leaves the blanking plate;
the blanking plate and the conveying surface of the conveying bin are arranged at an acute angle.
10. A method of operating a piezo-electric based screen material delivery device according to any of claims 1 to 9, wherein the method comprises:
placing the material on a hopper;
conveying the materials to a conveying assembly through a leakage hopper;
controlling the piezoelectric vibration component to start working and driving the conveying component to vibrate;
screening the materials in the conveying bin through a first screening plate and a second screening plate;
the materials clamped on the first screening plate are pushed out through the elastic columns.
