Description
Technical field
The invention belongs to the realm of building construction, especially relate to a kind of scattered dirt terrazzo polisher.
Background technology
Scattered dirt terrazzo polisher is mainly used in the polishing renovation to terrazzo floor.Terrazzo is a kind of artificial stone,
Have that density is big, hardness is high, wear-resisting, low price, easy construction the features such as.
With the rise of lithotome, the common terrazzo market competitiveness subtracts down increasingly.Terrazzo floor with its water absorption,
Full of flourishes, tidy up and liked by people well.Scattered dirt terrazzo polisher be exactly a kind of terrazzo floor is carried out nursing renovation
Machine for renewing stone, is a kind of wide variety of stone care equipment of modern society.
Terrazzo is a kind of artificial stone, have that density is big, hardness is high, wear-resisting, low price, easy construction the features such as.One
As for, the daily life of a family terrazzo floor maintenance be to be dragged with mop, terrazzo has water beautiful, when typically mopping floor, carries a water more
Contribute to maintenance ground.And, after ground water absorbing, then slowly evaporating makes that there was dampness in the air, particularly in winter to people again
Respiratory tract have certain benefit.
In the face of the air slaking of terrazzo, abrasion, only way is exactly by after the dirt removal of stone surface now both at home and abroad,
Stamp coating of wax.This method can play certain protective effect to new terrazzo surface, delay weathering, abrasion
Speed, but for air slaking, the terrazzo surface of abrasion, its effect is tantamount to clear in rotten wood brush last layer
Paint, can not reproduce the beautiful effect as mirror at all.And the cere of the so formation long property of guarantor is very poor, one week left side typically can only be kept
Wax again again in the right side.Not only frequently but also cost is very high for construction, and waxing is to take stopgap measures, and less talks and effects a permanent cure.Terrazzo it
So as bright as a sixpence, glittering and translucent, be primarily due to terrazzo after machining surface define one layer vitreous thin
Film, this layer film not only has a bright luster, and can go out the immanent structure level of stone material with Transparence Display is observed by people
Floral designs, beautiful aesthetic feeling is just here.Air slaking to be made, the terrazzo of abrasion recover its beautiful aesthetic feeling, and key is that logical
Cross terrazzo reconditioning technology and re-form glassy films in terrazzo surface.
So generally using polisher terrazzo is carried out with renovation polishing, reach purpose smooth again, but existing
Polisher, on the powder meeting stand-down that it spins out, staff is difficult to check polishing effect.
Content of the invention
The purpose of the present invention is to overcome the shortcomings of present technology, provides a kind of scattered dirt terrazzo polisher, solves existing
On the powder stand-down that some polishers are polished, impact staff checks the defect of polishing effect.
The present invention is achieved through the following technical solutions: scattered dirt terrazzo polisher, including the housing of lower ending opening,
It is provided with the grinding stone of circle, the lower end of grinding stone exceeds housing, and housing upper surface is provided with a motor, and motor drives mill in housing
Stone rotates, and housing is provided with the operating handle of an inclination, housing is additionally provided with scattered dirt device and dust exhaust apparatus, described
Scattered dirt device includes dissipating dirt ring and air pump, and scattered dirt ring is looped around on the side wall of housing, is provided with blowing mouth, blowing mouth below
Ringwise, described dust exhaust apparatus includes dust bin, the vacuum cleaner above housing and the dust bin around housing sidewall, inhales
Dirt ring is located at the top dissipating dirt ring, and the lateral wall of dust bin is covered with air suction opening.In this device, grinding stone is driven rotation by motor
Turn, grinding stone exposes housing, fits with ground, after rotation, is polished in ground, and staff holds operating handle, also grasps
Polish, grinding stone grinds powder, on the ground, staff is bad to check polishing effect to powder meeting heap, needs with sweeping out powder
Can also check, bother very much, so this device is provided with blowning installation, that is, dissipate dirt device, in scattered dirt device, scattered dirt ring connects gas
Pump, air pump, through dissipating dirt ring by air-blowing earthward, the dust on surrounding ground is blown off, staff can check polishing effect,
And setting dust exhaust apparatus siphons away dust it is ensured that in the air does not have too many dust, thus protecting staff on device
Healthy, the process of dust suction is, dust suction ring-side wall is provided with a circle air suction opening, and dust bin connects vacuum cleaner, and vacuum cleaner opens
Qi Hou, that is, pass through air suction opening draw air, thus bringing dust, dust can enter storage in dust bin.
Further, above-mentioned housing is provided with handle, facilitates the carrying of device, during carrying, a people catches operating handle,
One people catches handle.
Further, above-mentioned operating handle includes canned paragraph and rotational segment, and described canned paragraph is fixed on housing upper surface,
Rotational segment rotates the section that is connected, and the termination of canned paragraph is provided with vertical bolt, rotational segment is enclosed within bolt, and around spiral shell
Bolt rotates, and bolt arranges a nut, realizes the elastic of rotational segment by nut.Operating handle can be adjusted height,
To facilitate the staff of different heights, during loosening nut, rotational segment is rotatable, you can adjust gradient, thus adjusting height,
Tighten nut, that is, fix rotational segment.
The invention has the beneficial effects as follows: this device arranges a scattered dirt device, that is, be directed towards ground blowing, powder is blown
Fall, conveniently check polishing effect, also set up dust exhaust apparatus, draw the dust rising in blowing, prevent dust in air excessive,
Have influence on the healthy of staff.
