Title:
RESIDUE PREVENTING PLATE FOR POWDERY AND GRANULAR MATERIAL CARRYING CONVEYOR AND MOVEMENT ADJUSTER FOR CHAIN PULLEY
Document Type and Number:
Japanese Patent JP3546377
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To shortly achieve a properly spaced condition between a residue preventing plate and a chain pulley in a simple structure during work with the chain pulley being loosened and tensed and reset the chain pulley.
SOLUTION: A carrying conveyor containing a conveyor chain for laterally carrying powdery and granular materials to be put in a carrying duct is provided with the chain pulley 20 which is installed near the end of the carrying conveyor, as the circulation end of the conveyor chain, with its axially supported portions being movable to approach to and separate from each other. The residue preventing plate 24 having curved portions is longitudinally arranged along the outer periphery of the conveyor chain suspended on the chain pulley at a predetermined longitudinal and close space from its outer periphery contour. A gap-held moving mechanism is used to move the residue preventing plate in the same direction in synchronization with the approaching/separating movement of the chain pulley to/from the axially supported portions while holding a gap between the chin pulley and the residue preventing plate constant.
