Abstract
A device for dosing particulate material uses multiple valve plates to collectively open or close a discharge port, so that an opening degree of the discharge port can be adjusted according to the degree to which the adjustment ends of each valve plate are gathered, thereby effectively adjusting the opening degree of the discharge port. When the amount of particulate material to be dosed is large, the opening degree of the discharge port can be increased accordingly to increase the discharge speed of the particulate material, shortening the discharge time and improving the efficiency of dosing. Furthermore, the opening degree of the discharge port can be adjusted to be adapted with particulate material of different volumes, such that larger particulate material can also smoothly pass through the discharge port to avoid blockage of the discharge port.
