Abstract
Abstract A sawdust removing apparatus for a saw machine includes: a saw blade housing (9) for rotatably supporting a saw blade (15) for sawing work (W); a cleaning instrument (19) for removing sawdust adhering to the saw blade when work is being sawed; a cleaning instrument support member (21) pivotally supported by the saw housing for rotatably supporting the cleaning instrument; a cleaning instrument position adjusting device (23, 71) mounted on the saw housing for adjusting an overlap rate of the cleaning instrument with the saw blade; and a cleaning instrument position fixing device (25) mounted on the saw housing for fixing the cleaning instrument support member after the overlap rate of the cleaning instrument with the saw blade has been adjusted by the cleaning instrument position adjusting device. In the sawdust removing apparatus, since the cleaning instrument can be adjustably fixed any distance away from the saw blade by use of the cleaning instrument position adjusting device (23, 71) and the cleaning instrument position fixing device (25), it is possible to adjust the overlap rate of the cleaning instrument with the saw blade and further to prevent the cleaning instrument from being vibrated by the saw blade. Further, since a cleaning instrument separate device (hydraulic cylinder) (81) and a cleaning instrument life time sensor (proximity switch) (79) are provided, the cleaning instrument can be kept away from the saw blade when work is not being sawed and further the cleaning instrument can be replaced with a new one in a timely manner.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
159 words
A sawdust removing apparatus for a saw machine, comprising: a saw blade housing for rotatably supporting a saw blade for sawing work; cleaning instrument means for removing sawdust adhering to the saw blade when said work is being sawed; cleaning instrument support means movably supported by said saw blade housing for rotatably supporting said cleaning instrument means; cleaning instrument position adjusting means mounted on said saw blade housing for adjusting an amount of overlap of said cleaning instrument means with the saw blade; cleaning instrument position fixing means mounted on said saw blade housing for fixing said cleaning instrument support means after the amount of overlap of said cleaning instrument means with the saw blade has been adjusted by said cleaning instrument position adjusting means; and cleaning instrument separating means mounted on said saw blade housing for pivoting said cleaning instrument support means to separate said cleaning instrument means from the saw blade when work is not being sawed.
Claim 2
Dependent Claim
159 words
A sawdust removing apparatus for a saw machine, comprising: a saw blade housing for rotatably supporting a saw blade for sawing work; cleaning instrument means for removing sawdust adhering to the saw blade when said work is being sawed; cleaning instrument support means movably supported by said saw blade housing for rotatably supporting said cleaning instrument means; cleaning instrument position adjusting means mounted on said saw blade housing for adjusting an amount of overlap of said cleaning instrument means with the saw blade; cleaning instrument position fixing means mounted on said saw blade housing for fixing said cleaning instrument support means after the amount of overlap of said cleaning instrument means with the saw blade has been adjusted by said cleaning instrument position adjusting means; and cleaning instrument separating means mounted on said saw blade housing for pivoting said cleaning instrument support means to separate said cleaning instrument means from the saw blade when work is not being sawed.
