[0009] The pushing mechanism is configured as: when the control end of the pushing mechanism simultaneously receives the signals sent by the photoelectric switch and the time relay, the telescopic end of the pushing mechanism moves from the initial position to the preset position and then returns to the initial position.

[0010] In order to further implement the present invention, the following technical solutions can be preferably selected:

[0011] Preferably, the bracket is provided with a conveying mechanism, the upper surface of the conveying mechanism is flush with the upper surface of the bracket, and the conveying mechanism is located on one side of the bin away from the pushing mechanism.
