FEEDER FOR SUPPLYING POWDER AND GRAIN AND ITS FEEDING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a feeder for feeding the powder and grain, having a simple structure and capable of being inexpensively manufactured, or a feeder of the powder and grain capable of simultaneously feeding the powder and grain to different places from plural discharge ports by one feeder, and a feeding system of the powder and grain formed by combining the feeder and a computer.;SOLUTION: A cylindrical vessel 1 with an injection nozzle 3 is vibratable through a vibration generator 2 on the basis of a control signal from a computer 5 for controlling, a fixed amount of powder and grain 7 is stored in the cylindrical vessel 1 through a storage hopper 4 mounted on the cylinder vessel 1, and the vibration is applied to the cylindrical vessel 1, so that the powder and grain is injected and fed from the injection nozzle 3 by increasing the internal pressure in a powder and grain layer in the vessel by the relative motion and the squeezing among the powder and grain, and between the grain and a vessel wall face.;COPYRIGHT: (C)2002,JPO
