Then adjust the position of the pawl 50 so that it is in the first position, and the pawl 50 abuts against the ratchet wheel 20, thereby restricting the rotation of the ratchet wheel 20 in a certain direction; rotate the feeding hopper 30 so that the feeding hopper 30 drives the ratchet wheel 20 to rotate in the opposite direction, and the rotation of the ratchet wheel 20 gives the volute spring 40 energy storage, and the volute spring 40 stores mechanical potential energy; when it is necessary to put substances, operate the driving device 70 to make the pawl 50 overcome the elastic force of the elastic member 60 and move to the second position, releasing the restriction on the ratchet wheel 20 in a certain direction. At this time, under the action of the volute spring 40, the ratchet wheel 20 and the feeding hopper 30 start to rotate, realizing the uniform feeding of substances.
