Description
Technical field
The present invention relates to cleaning equipment technical field, more particularly to a kind of sewage sucking system of floor-cleaning machine.
Background technology
At present, with the lifting of living standard, requirement more and more higher of the people for environment tidiness.Then, in the market
Occur in that many cleaning equipments.Especially floor-cleaning machine, has got a lot of applications at present.Floor-cleaning machine is to be based on wet dedusting principle
A kind of cleaning equipment, be mainly used for drawing the sewage on ground, but often soil pick-up effect can not be ensured well, past
Toward after soil pick-up operation is carried out, scene still residual sewage.
The content of the invention
Applied to floor-cleaning machine suction combined system is scraped it is an object of the invention to provide a kind of, very thoroughly can draw ground
Sewage on face.
The object of the present invention is achieved like this：It is a kind of to scrape suction combined system, including curette, soil pick-up applied to floor-cleaning machine
Pipeline, recovery bin, blower fan, connecting seat, the blower fan are built in recovery bin；
The curette includes the seat of honour, is provided with by travelling the moving direction seat of honour that is defined two before and after front and rear both sides, the seat of honour
Side is cambered surface, and the seat of honour is rendered as crescent on the whole, and the seat of honour is arranged on vehicle frame rear portion by connecting seat；It is described
The curette also soft bar of liner including platy structure, interior sealing steel plate, the soft bar in outside, outer sealing steel plate；
Both sides are provided with multiple locating convex blocks before and after the seat of honour, and the soft plate face of bar one of liner is mounted on front side of the seat of honour, institute
State interior sealing another plate face of the soft bar of steel plate pressing liner；The soft plate face of bar one in outside is mounted on rear side of the seat of honour, the outer sealing
Soft another plate face of bar on the outside of steel plate pressing；It is distributed in the locating convex block on front side of the seat of honour and wears and connect the soft bar of liner, interior sealing steel plate, is distributed
Locating convex block on rear side of the seat of honour, which is worn, connects the soft bar in outside, outer sealing steel plate；
The curette also includes the soft bar of lockable liner, interior sealing steel plate, the soft bar in outside, the locking machine of outer sealing steel plate both sides
Structure, the locking mechanism is provided with a pair, and two locking mechanisms are separately mounted to the seat of honour left and right sides；
The soft bar of liner, the soft bar bottom in outside are contacted with ground, and gap is left between the seat of honour bottom and ground, and
The accommodating chamber of a sealing is formed between the soft bar of liner, the soft bar in outside, seat of honour bottom, the soft bar bottom of liner is along length side
To multiple sewage that hold are disposed with into the breach of accommodating chamber, the input of the soil pick-up pipeline is connected with accommodating chamber, described
The output end of soil pick-up pipeline is connected with recovery bin.
Compared with prior art, the beneficial effects of the present invention are：The mode that can be swept with reference to curette with vacsorb is come
Thoroughly remove the sewage on ground；During decontamination, start blower fan so that recovery bin and soil pick-up pipeline produce negative pressure, by accommodating chamber
Sewage be drawn into recovery bin, floor-cleaning machine moves forward so that the soft bar of liner, the bottom of the soft bar in outside directly sweep ground,
Sewage is from indentation, there flows into accommodating chamber, and sewage easily can enter in accommodating chamber, because accommodating chamber is sealing structure,
Sewage can be limited in accommodating chamber, because the soft bar of liner, the soft bar bottom in outside are contacted with ground, therefore, sewage is difficult to overflow
Go out, be easy to the input of soil pick-up pipeline to draw sewage, will not also produce secondary pollution；It is the soft bar of locking mechanism lockable liner, outer
Side Ruan Tiao both sides, therefore the soft bar of liner, the soft bar in outside also have good positional stability；The setting of locating convex block then can be so as to
In the installation soft bar of liner, the soft bar in outside so that both will not produce larger alignment error, and installation bases can be provided for both
It is accurate.
As the improvement of the present invention, the locking mechanism includes end connector, interior movable lock set, outer active lock group
Part, the end connector is removably mounted on the seat of honour；The outer movable lock set includes outer fastener, outer leaning seat, the
One connecting rod, described first connecting rod one end is hinged on end connector, and the first connecting rod other end is hinged on outer fastener, institute
Outer leaning seat is stated to be fixed on outer sealing steel plate, when need to pin it is outer seal steel plate and the soft bar in outside when, the outer fastener against
Outer leaning seat simultaneously pins outer sealing steel plate；The interior movable lock set includes interior fastener, interior leaning seat, second connecting rod, described the
Two connecting rod one end are hinged on end connector, and the second connecting rod other end is hinged on interior fastener, and the interior leaning seat is consolidated
It is scheduled on interior sealing steel plate, when sealing steel plate and the soft bar of liner in need to pin, the interior fastener is against interior leaning seat and locks
Firmly interior sealing steel plate.Advantage be locked out and unlock it is easy to operate, be easy to maintenance, it is easy to pin the soft bar of the soft bar of liner and outside, prevent
Only the soft bar of the soft bar of liner and outside produces loosening when sweeping ground.During installation, the soft bar of liner, interior sealing steel plate are mounted successively
On front side of the seat of honour so that locating convex block passes through the soft bar of liner, interior sealing steel plate, completed using locating convex block to the soft bar of liner, interior
The positioning of steel plate is sealed, then two locking mechanisms are installed, end connector is arranged on seat of honour left and right sides, is being needed in locking
When serving as a contrast soft bar, interior sealing steel plate, rotatable interior fastener causes interior fastener against interior leaning seat, in the interior button of two locking mechanisms
Under the common abutment action of part, interior sealing steel plate both sides are produced bending by top power effect, and steel plate is sealed inside and produces bending
When will the soft bar of pressing liner, so as to lock the position of the soft bar of liner.Outer fastener, outer leaning seat are former for the locking of the soft bar in outside
Reason is same as described above.
As a further improvement on the present invention, the communicating pipe that the soil pick-up pipeline includes dirt sucking tube, is fabricated from a flexible material,
The dirt sucking tube is straight tube structure, and the dirt sucking tube is installed on the seat of honour, and the dirt sucking tube lower end is connected with accommodating chamber, and
The dirt sucking tube lower end is close to ground, and the dirt sucking tube upper end is connected by communicating pipe with recovery bin.To draw accommodating chamber
In sewage.
