When a certain weight is reached, the motor 25 is turned off to stop feeding the raw material.

[0036] Then, the electric cylinder 15 is turned on to drive the push plate 13 to move, and the raw materials on the weighing box 12 are unloaded by the movement of the push plate 13, and the raw materials are prevented from remaining inside the weighing box 12;

[0037] Finally, the push plate 13 moves to drive the fixed bar 131 to move. When the two fixed bars 131 are respectively disengaged from the two rotating blocks 18, the spring 19 releases the deformation force to drive the rotating block 18 to rotate. The rotation of the rotating block 18 drives the rotating rod 17 to rotate. The rotation of the two rotating rods 17 drives the sealing cover 33 and the sealing plate 34 to rotate respectively. At this time, the transport pipe 3 is sealed by the sealing cover 33, and the discharge port is opened by the rotation of the sealing plate 34 to facilitate unloading.
