Abstract:
A wood planing machine comprising:a machine frame having right and left mounting sides spaced apart from each other in a longitudinal direction, each of said right and left mounting sides having upper and lower ends opposite to each other in an upright direction transverse to the longitudinal direction; a motor disposed on said machine frame adjacent to said lower ends of said right and left mounting sides, and having first and second output shafts defining first and second axes and extending in the longitudinal direction to deliver driving forces, said first and second output shafts being disposed opposite to each other in the longitudinal direction; a cutting member having a rotating shaft which is rotatably mounted on said right and left mounting sides and adjacent to said upper ends of said right and left mounting sides, and which extends in the longitudinal direction to define a third axis parallel to the first axis, and a cutting blade which is mounted on and which is rotated with said rotating shaft about the third axis; a first transmission member disposed to transmit the driving force of said first output shaft to said rotating shaft; a support carriage disposed on said right and left mounting sides and movable relative to said rotating shaft in the upright direction so as to cooperate with said rotating shaft to confine a path therebetween for passage of a workpiece; a shaving collecting member disposed on said machine frame to collect wood shavings, and confining a duct which has an intake port that is disposed in the vicinity of said cutting member, and an outlet port disposed downstream of said intake port and adjacent to said lower ends of said right and left mounting sides; a casing disposed under said support carriage, and having proximate and distal walls which are spaced apart from each other in the longitudinal direction and which are respectively proximate and distal to said outlet port to confine an accommodation chamber, said casing further having a discharge port which is disposed between said proximate and distal walls and which extends in a direction radial to the longitudinal direction, said proximate wall having an inlet port which is formed therethrough in the longitudinal direction and which is communicated with said outlet port so as to communicate said duct with said accommodation chamber; a drive shaft rotatably mounted on said distal wall, extending along a fourth axis parallel to the second axis, and having a first end which extends into said accommodation chamber, and a second end which extends from said first end and outwardly of said distal wall; a second drive transmission member disposed to transmit the driving force of said second output shaft to said second end of said drive shaft so as to rotate said drive shaft about the fourth axis when said motor is operated; and an impeller received in said accommodation chamber, and driven by said first end of said drive shaft to rotate about the fourth axis so as to draw wood shavings from said shaving collecting member into said accommodation chamber and out of said discharge port.
