Abstract
A tree chipper capable of reducing standing trees to chips has a rotating chipper, a feed mechanism for feeding trees into the chipper and a saw or the like for severing the trees. The tree chipper may comprise a boom that can be moved to position the tree chipper against a tree to be cut and chipped. In embodiments, the rotating chipper comprises a disc having chipping teeth on a face, a generally cylindrical chipper body having chipping teeth on an outer surface thereof and a conical chipper body.
Claims28
A chipper comprising:
- a circular saw having a peripheral edge and a face, the circular saw having cutting teeth around the peripheral edge and chipping teeth disposed on the face;
- a feed mechanism spaced apart from the face;
- a motor connected to operate the feed mechanism to feed a tree against the face while the circular saw is turning.
A chipper comprising:
- a frame defining a feed path for a tree, the frame supporting:
- a saw for severing a tree, the saw extendable into the feed path to sever a tree and retractable out of the feed path;
- a feed mechanism comprising a feed roller spaced apart from the saw to feed a tree along the feed path;
- and,
- a rotary chipping member carrying chipping teeth extendable into the feed path on a side of the saw away from the feed roller and retractable out of the feed path.
2 more elements
A chipper comprising:
- an undercarriage;
- a superstructure mounted to the undercarriage for rotation about a generally upright swing axis;
- a boom having a proximal end mounted to the superstructure, the boom being extendable and retractable relative to the superstructure;
- a chipping head mounted at a distal end of the boom, the chipping head comprising:
- a frame;
- a feed mechanism mounted to the frame;
- a rotary chipping member mounted to the frame at a location spaced apart from the feed roller along a feed path;
- and
- a motor connected to rotate the feed roller to feed a tree against the rotary chipping member while the rotary chipping member is turning.
6 more elements
A method for chipping a tree, the method comprising:
- bringing a tree chipper adjacent to the tree;
- in either order, severing the tree by urging a rotating circular saw carried on the tree chipper against the tree and grasping the tree at least in part by urging at least one feed roller against a trunk of the tree;
- and, driving the tree against chipper teeth on a face of the rotating circular saw to reduce the tree to chips at least in part by rotating the feed roller.
