Abstract
A drum chipper for chipping wood material includes a chipping drum having a blade mounted at an opening formed through a circumferential surface of the drum. The drum includes an internal conical surface positioned for a chip to flow radially inwardly from the blade towards the conical surface and outwardly through an axial face of the drum.
Claims15
A chipper for chipping wood material, said chipper comprising:
- a frame having a material inlet and a chip outlet;
- an engine;
- a chipping member carried on said frame and including at least one blade mounted in said frame for travel in a circumferential path of travel about an axis of rotation;
- said chipping member positioned for said blade to chip said material at said inlet to form chips and with said chips projected in a radial path generally radially inwardly from said blade toward said axis;
- said chipping member connected to said engine for said engine to drive said chipping member for said blade to move in said path of travel;
- said chipping member further including a deflection surface positioned for said chips to be deflected from said radial path to an axial path;
- said chip outlet positioned to receive said chips from said axial path.

A chipper for chipping wood material including brush and logs, said chipper comprising:
- a frame having a material inlet and a chip outlet;
- an engine;
- a chipping member carried on said frame and including at least one blade mounted in said frame for travel in a circumferential path of travel about an axis of rotation;
- said chipping member positioned for said blade to chip said material at said inlet to form chips and with said chips projected in a radial path generally radially inwardly from said blade toward said axis and outwardly in a generally radial path;
- said chipping member connected to said engine for said engine to drive said chipping member for said blade to move in said path of travel;
- said chip outlet positioned to receive said chips from said axial path;
- at least one discharge plate mounted for rotation about said axis as said blade moves about said axis, said discharge plate positioned to urge said chips from said axial path toward said chip outlet.
4 more elements
A chipper for chipping wood material including brush and logs, said chipper comprising:
- a frame having a material inlet and a chip outlet;
- an engine;
- a drum having a circumferential surface and at least a first axial face;
- said drum mounted for said circumferential face to oppose said inlet and with said chip outlet at said axial face and with said drum rotatable by said engine about an axis of said drum;
- said circumferential surface including at least one opening formed therein and having a blade positioned at said opening to form chips at said opening with said chips passing through said opening in a generally radial path;
- means within said drum for directing said chips from said radial path through said axial face.
