A plurality of support structures 2 are distributed at intervals on the first conveyor belt 4 for placing the material to be conveyed. The supporting structure 2 is provided with a first position for driving the material to be conveyed from top to bottom under the action of the conveying structure and a second position which deviates from the horizontal position when the material to be conveyed moves to be close to the lowest point of the conveying structure, so that the material to be conveyed is separated from the supporting structure 2 under the action of gravity, and the unloading action can be completed without other external force.

As a specific implementation manner, the supporting structure 2 is a zigzag plate body fixedly connected to the first conveyor belt 4, and a pair of plate bodies of the conveying structure at the same horizontal position form a placing space for the material to be conveyed when moving to positions close to each other, that is, the pair of plate bodies are close to each other when moving to the center of the frame body 1 and are far away from each other when moving to two sides of the frame body 1. Specifically, the first horizontal part of the zigzag shape is fixed with the first conveyor belt 4 by screws, the second horizontal part of the zigzag shape forms a supporting part of the placing space, and the distance between the two supporting parts is equal to the width of the blister box 17, so that the blister box 17 is prevented from shaking in the process of moving along with the first conveyor belt 4.
