At this time, the recessed part on the base of the hopper 6 is stuck together with the raised part on the sealing plate 8, and the hopper 6 can be stuck on the docking head 7 more stably.

[0044] During operation, by driving the sliding frame 14 to slide to the right, the sliding frame 14 drives the two first push rods 17 to move to the right, and the first push rod 17 drives the pull rod 18 to move to the right at the same time. When the pull rod 18 moves to the right, the second push block 13 on the hopper 6 is pulled to make the hopper 6 in the first storage box 4 move to the right; when the first push rods 17 on the front and rear sides move to the right to a certain extent, the inclined parts of the first push rods 17 on the front and rear sides begin to fit with the first push blocks 10 on the front and rear sides respectively, and as the first push rod 17 continues to move to the right, the first push rods 17 on the front and rear sides respectively push the first push blocks 10 on the front and rear sides to move forward and backward; when the inclined parts on the first push rods 17 pass over the first push blocks 10, at this time, the first push rods 17 on the front and rear sides are pressed against the first push blocks 10 on the front and rear sides. The first push block 10 starts to be stationary and the distance between the sealing plates 8 on the front and rear sides is greater than the width of the base of the hopper 6; as the first push rods 17 on the front and rear sides continue to move, the pull rods 18 on the front and rear sides pull the hopper 6 to move to the position above the collecting cylinder 2. When the hopper 6 is completely moved to the position directly above the collecting cylinder 2, the first push rod 17 just passes over the first push block 10, and the sealing plates 8 on the front and rear sides are reset to clamp the base of the hopper 6; at the same time, the sliding frame 14 drives the second push rod 41 to enter the deepest position in the first storage box 4, and the second push rod 41 pushes all the hoppers 6 in the first storage box 4 forward. When the second push rod 41 exits the first storage box 4, a new hopper 6 can be added from the left end of the first storage box 4.
