Abstract
A wood chipper which includes a chamber having a flywheel and which includes a wood in-feed system. The in-feed system includes a bin inclined for gravity-feeding wood product to the chamber and a cylindrical anvil disposed between an outlet of the bin and the flywheel. The flywheel includes a plurality of plates laminated together with fasteners. First and second ones of the plates have aligned first and second openings respectively for passage of chips. The second opening has a tab which extends from an edge thereof partially into the first opening. A knife is attached to the tab and supports a blade outwardly of the first plate and thus outwardly of the flywheel. A system is provided for providing water mist onto wood product only as it is being fed down the in-feed bin.
Claims7
A wood chipper comprising
- a chamber, an inlet chute for feeding wood material to said chamber,
- a flywheel rotatably received in said chamber,
- at least one knife attached to said flywheel and having a blade for cutting the wood material to form chips of the wood material as said flywheel is rotated,
- a nozzle for providing a mist of water onto the wood product to wet the wood product as the wood product is being fed along said inlet chute,
- a baffle hingedly attached at a hinge point to said inlet chute for hinged movement about said hinge point in response to the feeding of wood material along said inlet chute, a pump for pumping water to said nozzle,
- a switch for turning said pump on and off, and
- an actuator attached to said baffle and connected to said switch in a manner
- (1) for actuating said switch for turning said pump on to effect the water spray when said baffle is hingedly moved from a first position to a second position during the feeding of wood material along said inlet chute and
- (2) for de-actuating said switch for turning said pump off when said baffle is hingedly returned to said first position upon the ceasing of the feeding of wood material along said inlet chute.
