Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
See figures.1.and.2, a kind of Novel wall surface grinding machine, comprise casing, hollow aluminum pipe handle 1, motor 2, gear-box 3, polishing pad 4, the jackshaft rotated in order to polishing pad 4 and protective cover, described motor 2 is installed in described casing, described polishing pad 4 to be arranged on jackshaft and to be placed in described protective cover, described motor 2 is connected with described jackshaft by gear-box 3, described sander also comprises automatic dust absorption mechanism, described automatic dust absorption mechanism and described motor 2 are arranged in the both sides of described jackshaft, described automatic dust absorption mechanism comprises dust suction fan blade 51, blade shaft 52, blade cover and dust suction transmission mechanism, described dust suction fan blade 51 is positioned at described blade cover,
Described dust suction transmission mechanism comprises bevel gear wheel 6 and bevel pinion 7, described bevel gear wheel 6 is rotating to be arranged on fixed axis, described fixed axis is parallel with described jackshaft, power output shaft and the described fixed axis of described motor 2 are arranged vertically, on the same line, described fixed axis is between described blade shaft 52 and the power output shaft of described motor for the power output shaft of described blade shaft 52 and described motor;
Described bevel pinion 7 comprises one-level bevel pinion 71 and final stage bevel pinion 72, the power output shaft of described motor 2 is provided with one-level bevel pinion 71, described blade shaft 52 is provided with described final stage bevel pinion 72 in the one end near described fixed axis, described blade shaft 52 is provided with described dust suction fan blade 51 in the one end away from described fixed axis, described one-level bevel pinion 71 engages with the side of described bevel gear wheel 6, and described final stage bevel pinion 72 engages with the opposite side of described bevel gear wheel 6;
Described polishing pad 4 is provided with suction port, and the dust suction cavity connects in described suction port and described blade cover, described dust suction cavity is communicated with described hollow aluminum pipe handle 1 by sweep-up pipe 9.
Further, described hollow aluminum pipe handle 1 is also provided with the LED 10 in order to illumination.
Further again, described blade cover comprises front blade cover 53 and the rear blade cover 54 near described final stage bevel pinion 72, is provided with water conservancy diversion wind loop 55 between described rear blade cover 54 and described dust suction fan blade 51.
In the present embodiment, described hollow aluminum pipe handle 1 is installed on the housing by front fork 8, electric machine assembly and automatic dust absorption mechanism are arranged in the both sides of middle jackshaft respectively in polishing pad centered by jackshaft, thus are beneficial to the dust-proof of sander inside, are beneficial to again the anterior-posterior balance of polishing pad 4; Described front blade cover 53 and rear blade cover 54 form dust suction cavity.
Operation principle of the present utility model is: when motor 2 rotary work, the power output shaft of motor 2 drives one-level bevel pinion 71 to rotate, one-level bevel pinion 71 drives bevel gear wheel 6 to rotate, bevel gear wheel 6 drives final stage bevel pinion 72 to rotate, final stage bevel pinion 72 drives blade shaft 52 to rotate, blade shaft 52 drives dust suction fan blade 51 to move, thus the dust suction cavity in blade cover produces negative pressure, the dust produced when machine is polished is inhaled in the dust suction cavity in blade cover by the suction port on polishing pad 4, last dust is discharged by sweep-up pipe 9 and hollow aluminum pipe handle 1.
