Abstract

The invention relates to a self-dust-collection wall polishing machine. The self-dust-collection wall polishing machine comprises a polishing plate and a disc shell used for packaging the polishing plate. A dust outlet channel is formed in the bottom end of the disc shell so that dust in the disc shell can enter the dust outlet channel in the bottom end of the disc shell under the action of gravity when a wall is polished through the polishing disc, the problem that the dust is detained in the disc shell is effectively solved, and the dust collection effect is greatly improved. The self-dust-collection wall polishing machine further comprises a rotatable dust collection impeller and a cylindrical dust collection bin used for packaging the dust collection impeller. The bottom of the cylindrical dust collection bin communicates with the dust outlet channel. When the dust collection impeller rotates, negative pressure is formed in the cylindrical dust collection bin, and the dust in the disc shell can enter the cylindrical dust collection bin through the dust outlet channel, so that the dust collection effect is ensured.

Description

A kind of self-dust-suction wall polishing machine

Technical field

The present invention relates to a kind of polishing wall surface machine, particularly a kind of self-dust-suction wall polishing machine.

Background technology

Wall surface grinding machine/polishing machine is widely used in interior decoration, during metope is polished, can produce A large amount of dust, in order to ensure in the course of work, operator's is healthy, and present wall surface grinding machine is equipped with dust suction knot Structure.

Polishing machine with dust collection mechanism of the prior art, commonplace has two kinds of forms, and the first is that China is special Disclosed in sharp application publication number CN 102430981 A, a kind of offer self-dust absorption type polishing machine, including casing, is located at casing sidepiece Main handle, staggering with main handle forms the assist handle of angle, is located at the polishing pad of case head, is provided with to beating in described casing Mill provides the motor of power, and described case head is additionally provided with the disk of protection polishing pad, shape between described disk and polishing pad Become the cavity being in communication with the outside, be provided with the dust absorption passage connecting with cavity in described casing, described main handle bottom is provided with and inhales The dust outlet tube of dirt channel connection, is provided with the dust suction fan blade being provided by power with motor connection in described dust absorption passage；Above-mentioned throwing The dust suction fan blade of ray machine and polishing pad are coaxially disposed, therefore dust absorption passage being radially arranged perpendicular to polishing pad；This type Polishing machine also includes sand milling polishing dust-absorbing integral sanding disclosed in Chinese patent application publication No. CN101434049A Machine, dust exhaust apparatus of stock wall surface grinding machine etc. disclosed in Chinese patent application publication No. CN103056778A, the said equipment Feature is that dust suction blade is coaxially disposed with polishing blade, and farther out, manipulation is inconvenient for the polishing machine centroidal distance metope of acquisition.

Second is a kind of integral type aspiration buffing machine disclosed in Chinese patent notification number CN 205085768 U, including electricity Machine, angular wheel, polishing wheel, dust suction air-introduced machine, the side of described angular wheel is engaged with the output shaft of described motor and is connected, institute State the relative opposite side of angular wheel and the first gear axle parallel to described motor output shaft engages and is connected, described first gear Axle is fixedly linked with described dust suction air-introduced machine, drives described dust suction air-introduced machine rotation；It is coaxially disposed below described angular wheel Two gear shafts, the engagement of described second gear axle connects the 3rd gear shaft of adjacent, parallel setting, described 3rd gear shaft with described Polishing wheel is fixedly linked, and drives described polishing wheel rotation, and the rotation of the direction of rotation of described polishing wheel and described motor output shaft Turn direction vertical；The output shaft of motor is vertically arranged with polishing wheel main shaft by above-mentioned sanding machine by angular wheel, reduces throwing Ray machine center of gravity is to the distance of wall, but dust suction air-introduced machine is arranged on the top of motor output shaft.

The polishing machine of above two structure, due to dust absorption fan is preposition or on put, polishing machine center of gravity can be led to higher, in height Lift job state under malfunction, due under Action of Gravity Field polishing machine can deflect down cause polishing disk away from work metope, Lead to polishing effect not good；Because when polishing machine is polished, dust can descend slowly and lightly downwards in gravity in polishing machine, and prior art , not located at the lower section of polishing machine, therefore pick-up performance is poor, is unfavorable for the collection of dust for dust suction storehouse entrance.
