Abstract
A chipping machine having an elongated, rotatable chipping member, the chipping member having at least one cutting blade and defining at least one blade opening adjacent the cutting blade. A paddle is provided on the chipping member which is associated with the blade opening and which extends radially with respect to the axis of rotation of the cutting member. The paddle preferably includes a tapered-in portion tapered inwardly toward the axis of rotation of the chipping member. A discharge chute is provided for receiving the chips cut from the article by the chipping member. The discharge chute preferably includes a generally semi-circular portion having a diameter greater than the chipping member and defines a chip path volume of generally semi-circular cross-sectional shape.
Claims22
A machine for chipping an article, comprising:
- an intake for receiving the article;
- an elongated chipping member for receiving the article from said intake and for cutting chips from the article, said chipping member being rotatable and defining an axis of rotation;
- a motor drivingly connected to said chipping member for selectively rotating said chipping member;
- said chipping member having at least one cutting blade and defining at least one blade opening adjacent said cutting blade;
- at least one paddle associated with said blade opening, said paddle extending radially with respect to said axis of rotation of said cutting member and said paddle having a tapered-in portion tapered inwardly toward said axis of rotation;
- and
- a discharge chute for receiving the chips cut from the article by the chipping member, said discharge chute defining a discharge opening, and said discharge chute defining a chip path through which the chips travel;
- said discharge chute defining an arched wall forming a portion of said chip path, and said arched wall being at a higher elevation than both said chipping member and said discharge opening.
