Down. A pair of transmission structures located on the same side of the frame body 1 are respectively arranged on the front and rear sides of the frame body 1 to ensure the stability of transmission. The transmission structure includes a pair of transmission wheels 3 and a pair of transmission wheels 3 on The first transmission belt 4, a pair of transmission wheels 3 at the same horizontal position are fixed on the frame body 1 through the rotating shaft 5 and the connecting rod 6 arranged on the rotating shaft 5, and a pair of the transmission wheels positioned on the same side of the frame body 1 The transmission wheel 3 is vertically distributed along the height direction of the frame body 1, the transmission wheel 3 at the top is a driving wheel, the driving wheel is connected with the motor 18, the driving wheel rotates under the drive of the motor 18, and then drives the slave wheel located at the bottom The wheel turns. A plurality of supporting structures 2 are distributed on the first conveyor belt 4 at intervals, and are used for placing materials to be transported. The support structure 2 has a first position where the material to be conveyed is transported from top to bottom under the action of the conveying structure and when the material to be conveyed moves to the lowest point close to the conveying structure, The second position deviates from the horizontal position so that the material to be transported is detached from the support structure 2 under the action of gravity, so that the unloading action can be completed without any other external force.

As a specific implementation, the support structure 2 is a Z-shaped board fixedly connected to the first conveyor belt 4, and a pair of boards of the transmission structure at the same horizontal position move to a position close to each other. When forming the storage space for the materials to be transported, a pair of boards approach each other when they move to the center of the frame body 1, and move away from each other when they move to both sides of the frame body 1. Specifically, the Z-shaped first horizontal part is fixed to the first conveyor belt 4 by screws, and the Z-shaped second horizontal part forms the support part of the placement space, and the distance between the two support parts is equal to the blister box 17 Width, to prevent the blister box 17 from shaking during the movement with the first conveyor belt 4.
