Abstract: An apparatus is adapted for discharging wood shavings that are generated during operation of a wood planing machine. The wood planing machine includes a machine base, a cutter support, a rotary cutter, and a drive unit. The apparatus includes a fan unit and a shavings collecting box. The fan unit includes a fan housing, a fan blade, and a drive shaft. The shavings collecting box has an open top disposed below a discharge hole in the cutter support so as to receive the wood shavings that fall therethrough, a closed bottom, and a lateral wall formed with an outlet port adjacent to the closed bottom. The rotation of the fan blade in the blade chamber causes the wood shavings that fall into the box to be drawn into the blade chamber via the outlet port and an inlet port in the fan housing and to be subsequently discharged through a discharge tube in the fan housing.

Abstract: A wood planing machine includes a base, four hollow posts extending upright from the base and formed with slots, four screw rods disposed in the posts, four sprockets connected respectively to the screw rods, a chain engaging the sprockets, a cutter carriage including a pair of carriage seats mounted on the posts, four threaded members mounted adjustably on the carriage seats and having sector-shaped threaded portions that threadedly engage the screw rods, and four eccentric members mounted rotatably on the threaded members. Each eccentric member includes a shaft and an eccentric wheel that constantly engages a respective threaded member and that is rotatable between first and second engaging positions in which the respective threaded member is moved upwardly and downwardly.

Abstract: A planing machine includes a support bed disposed within a machine body. A rod unit is mounted on the machine body, and is operably associated with the bed such that rotation of the rod unit results in movement of the bed within the machine body. A slide element is disposed slidably on the rod unit, and carries first and second bevel gears thereon. A toothed driving wheel is disposed adjacent to the slide element. The bevel gears are coupled to the rod unit for co-rotation therewith. The slide element is movable on the rod unit to a first position, where the first bevel gear meshes with and is driven by the driving wheel to permit the rod unit to rotate in a first direction, and to a second position, where the second bevel gear meshes with and is driven by the driving wheel to permit the rod unit to rotate in a second direction that is opposite to the first direction.

Abstract: A grinding device includes a grinding wheel member driven by an output shaft of a motor. A drive transmission member transmits the driving force of the output shaft to a rotating shaft to operate a blowing member when the motor is actuated. A dust collecting member is disposed in the vicinity of the grinding wheel member for collecting dust during a grinding operation. An elongated hollow member is disposed between the collecting member and the blowing member so as to draw dust from the collecting member to the blowing member.

Abstract: In a wood planing machine having rotatable screw rods and a cutter carriage with threaded members that engage the screw rods, a gear mounting seat is slidable along a drive shaft that is parallel to and that is rotatable with the screw rods. Upper and lower driven gears are mounted on the gear mounting seat and are capable of selective engagement with a drive gear on a drive axle of a motor-driven rotary cutter on the cutter carriage. The arrangement as such permits motor-driven height adjustment of the cutter carriage.
