Abstract:
A wood planing machine comprising:a mounting frame having upper and lower ends opposite to each other in an upright direction; a support carriage mounted on said mounting frame and movable between said upper and lower ends in the upright direction, said support carriage having right and left sides opposite to each other in a longitudinal direction transverse to the upright direction, and front and rear sides opposite to each other in a transverse direction relative to the longitudinal and upright directions; a motor housing mounted on said support carriage; a motor with an output shaft which is received in said motor housing; an air duct disposed adjacent to said right side for passage of introduced air, and having a communicating port; a rotatable cutting shaft mounted on said support carriage, driven by said output shaft to be rotatable about an axis extending in the longitudinal direction, and having a coupling end which extends leftwardly and outwardly of said left side; a shaving collecting member disposed on said support carriage to define a shaving passageway for collecting wood shavings, said shaving passageway having an intake port which is disposed in the vicinity of said cutting shaft, and an outlet port which is disposed downstream of said intake port and adjacent to said left side; an air conduit defining a flow channel which is in fluid communication with said communicating port, which is disposed upstream of said outlet port of said shaving passageway, and which extends in the transverse direction to permit an air stream to flow in the transverse direction; an air stream directing member disposed on said support carriage to direct the air stream to move along a flow route which extends in the longitudinal direction and cross said shaving passageway, such that the air stream flowing along said flow route passes by said intake port so as to entrain wood shavings thereinto for onward movement to said outlet port; a blower casing disposed leftwardly of said left side, and having proximate and distal walls which are spaced apart from each other in the longitudinal direction and which are respectively proximate to and distal from said left side to define an accommodation chamber, said proximate wall having an inlet port which is formed therethrough and which is communicated with and which is disposed downstream of said outlet port; a tubular discharge member disposed between said proximate and distal walls, in fluid communication with said accommodation chamber, and extending in a direction radial to the longitudinal direction; a drive shaft extending along the axis, and having a first end which is rotatably mounted on said distal wall, and a second end which is disposed opposite to said first end and which extends through said inlet port to be coupled to and rotated with said coupling end of said cutting shaft; and an impeller received in said accommodation chamber, and connected to and driven by said first end of said drive shaft to rotate about the axis so as to draw the wood shavings from said shaving passageway into said accommodation chamber via said inlet port and out of said discharge member.
