Wherein the weighing module 200 is mounted on the frame body 100.

The top end of the weighing bin 300 is erected on the weighing module 200, and the discharge port of the weighing bin extends into the frame body 100.

The spiral conveying device 400 is arranged in the frame body 100, and a feed inlet of the spiral conveying device 400 is connected with a discharge outlet of the weighing bin 300.
