Description

A kind of hand-held folds push plate fiber medium electric cleaning machine
Technical field
The present invention relates to a kind of flooring cleaner, it is electronic clear that more particularly to a kind of hand-held folds push plate fiber medium Clean machine.
Background technology
Flooring cleaning machine is quickly grown in recent years, and domestic and international leading products are floor-cleaning machine and floor cleaning machine.Floor-cleaning machine Technology maturation, is generally used abroad, is gradually promoted at home.Motor driving water pump is utilized when floor-cleaning machine works Ground is washed with ground brush is washed, and is taken off by water and ground sewage is sucked into sewage cylinder, its advantage is efficient and convenient, cleaning effect is good, over the ground Face spot cleaning ability is strong, and shortcoming is limited by operation principle and structure, and working width is limited, cleans process energy consumption Greatly, and price is high.Floor cleaning machine is divided into two class of fixed mop and variable mop by mop form.Fixed mop floor cleaning machine structure Simply, working width is big, and cleaning process energy consumption is small, but deficiency is that pollutant is mainly gathered in mop front end, and during reciprocating reversing Secondary pollution can be produced again, and this phenomenon is especially prominent when manually mopping floor and is difficult to avoid that.Variable mop floor cleaning machine compensate for Upper deficiency, but its structure is relative complex, is unfavorable for wide cut operation, and course of work energy consumption is big.Traditional sawdust push plate mops floor mode With clean mop floor can once complete, the outstanding advantages that working width is big, cleaning effect is good and clean surface easily converts, but it is scarce Point is also apparent from:Sawdust raw material can only be disposable, and when operation will arrange sawdust form repeatedly, and it is artificial that folding and unfolding, which arranges, Operation, thus its application is rare.
The content of the invention
For above-mentioned technical need, it is electronic to fold push plate fiber medium it is an object of the invention to provide a kind of hand-held Cleaner, it can realize the machinery recycling and lifting of electric drive operation, folding push plate and its fiber cleaning medium, cleaner Travel position can enter standard lift and transport, and cleaning is reliable and stable, and safe operation is convenient, to better adapt to large-scale public field The requirement for cleaning of institute flooring.
Technical solution is used by realizing foregoing invention purpose:It is electronic clear that a kind of hand-held folds push plate fiber medium Clean machine, including electrically driven truck, storage battery and control panel, the storage battery are installed on electrically driven truck;The chain of command Plate is installed on the steering handrail of electrically driven truck, and by controlling cable to be connected with motor, the front end of the electrically driven truck is set Folding push plate is equipped with, the folding push plate is hinged on before push plate recovering mechanism by push plate link, and the push plate is returned The front upper place that mechanism is arranged in electrically driven truck is received, push plate elevating mechanism is arranged on the back upper place of electrically driven truck.
The folding push plate is made of the left and right folded section of plate fixed section and L types, and hinge is used between three sections Connection, and being driven by a push-rod electric machine and symmetrical fold linkage mechanism, a certain number of fiber cleaning balls are deposited in during work It is U types in the folding push plate of hollow, folding after push plate is opened, auger makes fiber cleaning ball to both sides push It is evenly distributed with along push plate, and cleaning face is formed before fiber cleaning ball group, and bottom surface forms the face that mops floor, and is promoted by push plate and realizes that wide cut is clear Sweep and mop floor operation, the folding of push plate and the agitation of auger can constantly convert cleaning face and the face that mops floor, push plate fold For fiber cleaning ball can be surrounded in it after hollow, and push plate fiber medium electric cleaning machine is folded by its time by hand-held Receive and rise switchs to travel position.
The push plate recovering mechanism is pushed away by push plate link, linear cylindrical guide rail, guide rail bearing, recycling balladeur train and recycling Bar motor is formed, and the linear cylindrical guide rail is arranged on the top in rack, and linear cylindrical guide rail is installed above lead rail axis Hold, sliding block of the recycling balladeur train respectively with guide rail bearing and recycling push-rod electric machine is connected, the push plate link point Not with behind fixed section push plate and recycling balladeur train is above hinged, the recycling push-rod electric machine hinge is mounted on rear in rack Portion.
The push plate elevating mechanism is made of lifting supporting plate, supporting plate hanger bracket, lifter drawing bar and lifting push-rod electric machine, institute The lifting supporting plate stated is to be arranged on a forward dustpan shape supporting plate of opening of front lower portion in electrically driven truck, by being connected by parallel four The supporting plate hanger bracket hinge of linkage composition is filled and is suspended in rack, and lifting rocking bar frame hinge is mounted in the outside of central rack, lifting Short rocking bar on rocking bar frame is hinged by lifter drawing bar and lifting supporting plate, lifts the long rocking bar on rocking bar frame by coupling bar with rising The push rod of drop push-rod electric machine is hinged, middle and back of the lifting push-rod electric machine hinge above rack.
Thrust failure prote is further included, the thrust failure prote is by thrust force protection bearing support and thrust force protection rubber block Form, the thrust force protection bearing support is arranged on rack front end both sides, is provided with thrust force protection rubber block thereon.
Folding, recycling, lifting and the release of push plate, and the driving power that electrically driven truck is advanced are provided by storage battery, respectively The startup and stopping of driving device and the setting of job order use intelligent control, and by controlling cable to be integrated into chain of command On plate.
The hand-held of the present invention cleans when folding the work of push plate fiber medium electric cleaning machine and mops floor and can once complete, and has Operation wide cut is big, cleaning process energy consumption is small, cleaning effect is good, cleaning process is mainly by driven by power, compact-sized durable, clear The characteristics of clean medium is reusable, place is adaptable is, it can be achieved that to airport, station, hospital, workshop, stadiums, film and drama The large-scale public places such as institute, office building and energy-efficient, the safe and reliable prune job of corridor flooring.
