Abstract:
1. A cutting machine, comprising: a cutting support frame comprising a bottom collecting tray and a cutting table mounted thereon for supporting a work piece; a motor assembly, which is supported above said bottom collecting tray, comprising a driving motor; a cutting head arrangement comprising a cutting blade which is overhanging said cutting table and powered by said driving motor, wherein said cutting blade has a cutting area defined at an outer circumferential portion thereof when said cutting blade cuts said work piece; and an environment control arrangement, comprising: an end collecting tray, which is upwardly extended from a rear end portion of said bottom collecting tray to form a L-shaped structure, having a collecting chamber for collecting residual particles of said work piece while said cutting blade cuts said work piece, wherein said end collecting tray is upwardly extended to a position above said cutting area of said cutting blade, wherein said end collecting tray has a predetermined height adapted for reflecting said residual particles of said work piece to said bottom collecting tray and for blocking said residual particles spitting out of said collecting chamber of said end collecting tray; and a suction source having a sucking inlet provided at a lower portion of said end collecting tray for collecting said residual particles within said collecting chamber by means of sucking effect, wherein said suction source comprises a collection pen and means for sucking said residual particles from said sucking inlet to said collection pen, wherein said collection pen comprises a standing frame having a top frame, a collecting bag having a top opening supported by said top frame of said standing frame to define a collection cavity within said collecting bag, and a cover guide which is supported on said top frame of said standing frame and comprises a plurality of dust guiders extended downwardly into said collection cavity, wherein said dust guiders are capable of guiding said residual particles into said collection cavity when said sucking means sucks said residual particles to said cover guide from said sucking inlet, wherein said sucking means comprises a directing cylinder supported on said cover guide, an extension hose extended from said sucking inlet to said directing cylinder, and a suction motor operatively connected to said extension hose for reducing an air pressure at said sucking inlet so as to suck said residual particles into said collecting pen, wherein a diameter of said extension hose is smaller than that of said directing cylinder for slowing down a speed of said residual particles passing from said extension hose to said directing cylinder.
