Brush chipper assembly with counter-rotating feeder rollers and chipping heads

摘要

A brush chipper assembly has a housing and a feeder subassembly connected to the housing. The feeder subassembly includes opposed, first and second feeder rollers. When the feeder subassembly is actuated, the first feeder roller is operable to rotate in a first direction and the second feeder roller is operable to rotate in a second direction (opposite to the first direction) so as to draw the brush into the housing. Also provided is, a chipping subassembly substantially contained within the housing behind the feeder subassembly. The chipping subassembly including first and second, opposed chipping heads, each of which carrying cutting teeth for chipping the brush. When the chipping subassembly is actuated, the first chipping head is operable to rotate in a third direction (opposite to the first direction) and the second chipping head is operable to rotate in a fourth direction (opposite to the second direction).

主权项

1. A brush chipper assembly comprising:
a housing; a feeder subassembly connected to the housing; the feeder subassembly including opposed, first and second feeder rollers; when the feeder subassembly is actuated, the first feeder roller is operable to rotate in a first direction and the second feeder roller is operable to rotate in a second direction so as to draw the brush to be chipped into the housing; the first direction being opposite to the second direction; whereby the first and second feeder rollers are biased in respective first positions; when the feeder subassembly is actuated, the first and second feeder rollers are capable of being actuated to second respective positions, thereby adjusting the size of a gap defined by outer boundaries of the first and second feeder rollers; a chipping subassembly substantially contained within the housing behind the feeder subassembly; the chipping subassembly including first and second, opposed chipping heads and a drive assembly for driving rotation of the first and second chipping heads; each chipping head carrying a plurality of cutting teeth for chipping the brush fed into the brush chipper assembly; when the chipping subassembly is actuated, the first chipping head is operable to rotate in a third direction and the second chipping head is operable to rotate in a fourth direction; the third direction being opposite to the fourth direction and the first direction; the fourth direction being opposite to the second direction.
