摘要： A floor grinding device is provided to permit dust to be sucked smoothly into a dust collector from a dust collecting cover by introducing outdoor air into the dust collecting cover when indoor air is sucked by the dust collector. A floor grinding device includes a main body(10), a dust collecting cover(20), a dust collector(40), a grinder(30), a suction unit, an anti-scatter cap(50), and an elastic support unit(60). The main body is equipped with a motor. The dust collecting cover includes a disk(21) having an opening formed along a circumference thereof, a cylindrical portion(23) formed beneath the disk and has a circumference contacting an inner surface of the anti-scatter cap, a joint portion(24) formed on a center of the disk and jointed to the main body, and a suction pipe(25) arranged at one side of the disk and connected to the dust collector so as to suck air from the cylindrical portion into the dust collector. The dust collector is connected to the dust collecting cover. The grinder is arranged within the dust collecting cover, and connected to the motor so as to grind a floor. The suction unit is mounted on the disk arranged between cutter blades(33), and has suction holes having angles of 45 to 60 degrees relatively to a vertical line so as to suck air from the periphery of the cutter blade onto the disk during rotation of the grinder. The anti-scatter cap is arranged along the circumference of the dust collecting cover, and has a flat bottom surface contacting the floor such that dust in the dust collecting cover from being scattered. The elastic support unit includes a threaded shaft(61) having a top positioned within the opening of the dust collecting cover and a bottom screwed into the anti-scatter cap, a nut(64) tightened onto the shaft, and a coil spring(65) arranged along a circumference of the threaded shaft, and has both ends supported at the dust collecting cover and the anti-scatter cap so as to support the anti-scatter cap.
