Title:
BULK MATERIAL FEEDER
Document Type and Number:
Japanese Patent JP2016030681
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent occurrence of center run-out such that an auger contacts an inner periphery of a transportation guide cylinder.SOLUTION: A bulk material feeder includes: a vertically directed transportation guide cylinder 21 which guides and discharges a bulk material; an auger 31 which is rotated in the transportation guide cylinder and transports the bulk material; a projection member 45 which is provided coaxially with a lower end part 31b of the auger 31; and a center rest ring 54 which is provided coaxially with a lower end part 21a of the transportation guide cylinder 21 and has an open hole 54a for receiving the projection member 45. Between the projection member 45 and the open hole 54a, a clearance G2, which permits approach of the bulk material and is narrower than a clearance G3 between the transportation guide cylinder 21 and the auger 31, is formed. Since the projection member 45 and the open hope 54a come into contact with each other even if center run-out occurs, the auger 31 does not cause center run-out to the extend that the auger comes into contact with an inner periphery 21b of the transportation guide cylinder 21.SELECTED DRAWING: Figure 3
