Abstract
A mine dusting machine comprising a specialized hopper or scoop bucket having a floor, sides and ends and adapted for carrying substantially free-flowing particulate material, a powered ram on the hopper for pushing the material therein toward the front end thereof, a powered conveyor mounted within the hopper adjacent the front end for transporting the material toward opposite sides of the hopper, separate flingers mounted on the front end at least adjacent each of the sides and adapted to receive the material transported thereto by the conveyor, each of the flingers means having at least one rotatable blade for dispersing the material with considerable force in a generally arcuate pattern.
Claims30
A dusting machine comprising a specialized hopper or scoop bucket having a floor, generally opposite sides and generally opposite front and rear ends and adapted for carrying substantially free-flowing particulate material, the planes of said sides being substantially parallel to maximize the capacity of said hopper, powered ram means on said hopper for pushing said material therein toward said front end thereof, said ram means extending substantially the full width of said hopper, powered conveyor means mounted within said hopper adjacent said front end and substantially parallel thereto for transporting said material toward each of said opposite sides of said hopper, separate multiple flinger means mounted on said front end, at least one said flinger means being provided adjacent each of said opposite sides and adapted to receive said material transported thereto by said conveyor means, each said flinger means having rotatable blade means for dispersing said material with considerable force in a generally arcuate pattern.
Flinger means for use on rock dusting machines comprising a housing, dust outlet means in the upper portion of said housing subtending an outlet arc of at least about 180 degrees having a lead segment of from about 25 degrees to about 55 degrees, blade means connected to shaft means rotatably mounted in said housing, dust inlet means in said housing adapted to communicate with a dust hopper, power means connected to said shaft means for rotating said shaft means and said blade means, said blade means comprising two blades angularly offset approximately 180 degrees and axially adjacent on said shaft means, said blades being mounted on opposite sides of plate means the plane of which is substantially normal to the axis of said shaft means, said plate means comprising two substantially angularly opposed segments attached to said shaft means, and said housing being provided with shield means for blocking said lead segment of said outlet arc for one of said blades.
