Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation.
As shown in Figures 1 to 4, the Multifunctional floor-sweeping car, including chassis 2 and the water tank 7 that is located on chassis 2, under chassis
Side is provided with side brush mechanism assembly and main brush mechanism assembly, and side brush mechanism assembly is located at the front of main brush mechanism assembly, set on chassis
There is the high-pressure pump 8 being connected with water tank, high-pressure pump 8 is connected with High Pressure Gun 9；It is connected between high-pressure pump and High Pressure Gun by high-voltage tube, it is high
Pressure rifle hangs over the side of water tank, is easy to use.
Chassis 2 is provided with shell 1 and power battery pack 3 and electric-control system 12, and full car is pure electronic, energy-conserving and environment-protective, and
The spray head 13 being connected with water tank is provided with Chinese herbaceous peony, side brush can kick up the dust on ground generation airborne dust, spray head spray when rotating
The water smoke gone out plays depositing dust effect.
Side brush is disc brush, and main brush is round brush, is cleaned comprehensive；Single High Pressure Gun is equipped with simultaneously, can be to ground stain
Remove, dustbin capable of washing, greenbelt, road curb etc., be widely used；And the main rotatable rising of brush is good by property.
Side brush mechanism assembly includes front side brush mechanism assembly 4 and back brush mechanism assembly 5, and front side brush mechanism assembly, which is located at, to be swept
The front of ground Chinese herbaceous peony wheel, back brush mechanism assembly are located at the rear of road sweeper front-wheel, an opposite side brush of front side brush mechanism assembly it
Between distance be more than back brush mechanism assembly an opposite side brush between distance.
The side of front side brush mechanism assembly and back brush mechanism assembly is brushed to internal rotation, is cleaned by front side brush mechanism assembly
Both sides rubbish, then gathered rubbish to centre from back brush mechanism assembly, then thrown rubbish into dustbin 15 by main brush.
Main brush mechanism assembly includes main brush box body 6 and the main brush 14 being located on main brush box body, is provided with main brush box body rear portion
Dustbin 15, dustbin can be extracted out out of main brush box body, in addition to electric pushrod 10, rod 11 and lifting shaft, main brush box body
Side be hinged on chassis, lifting shaft is located at the opposite side of main brush box body, and one end of the electric pushrod is hinged on chassis,
The other end of electric pushrod and one end of rod are hinged, and the rod other end is located at below lifting shaft, and rod is hinged on chassis.
Also include the push rod mounting bracket being hinged on chassis, one end of push rod mounting bracket and one end phase of electric pushrod
It is be hinged, extension spring is provided between the other end of push rod mounting bracket and chassis.
Push rod mounting bracket is pulled back with extension spring, push rod mounting bracket keeps pulling force all the time backward, makes electric pushrod
All the time top forward；When electric pushrod is released, promotion rod front end rotates up, and provokes lift shaft, and lift shaft drives master
Brush box body rotates upward motion around rotary shaft, rises main brush box body.
When electric pushrod retraction, rod is retracted, main brush box body deadweight is fallen；The situation that main brush box body rises, in injustice
Road traveling when car can jolt, the power that extension spring buffers to electric pushrod, protection electric pushrod will not run it is bad.
The liftable adjustment of main brush box body 6, main brush box body is lifted, rubber will not be caused to be rubbed when deceleration strip is crossed
Bad failure, improve the passing through property of road sweeper；And Electronic control, elevating control are easy to operate.
Main brush mechanism assembly also includes dust absorption fan 19 and the dust suction casing being located on main brush box body, is located at dust suction casing
The under shed of bottom connects with main brush box body phase, and the side of dust suction casing is provided with side opening, and dust absorption fan is located at side opening, inhales
The filter vat 18 rotated is provided with dirt casing, the scraper plate 16 for being used for contacting with the filter paper of filter vat is provided with suction box body.
Dust suction casing is provided with shake dirt motor 17, and chain is connected between shake dirt motor 17 and the rotating shaft of filter vat 18.Scraper plate
For rubber board, scraper plate is arranged on subordinate's opening in suction box body, avoids scratch filter paper.
Full car is pure electronic, and power source of the power battery pack as vehicle, chassis is as carrier；By front side brush, mechanism is total
Rubbish is gathered to centre into cleaning both sides rubbish, then from back brush mechanism assembly, then thrown rubbish into dustbin by main brush,
Realize refuse collection；When car works, the rubbish of weight is thrown into dustbin as parabolic motion when main brush is swept the floor at a high speed, dust
It can be kicked up, dust is drawn onto on dust-absorbing filtering bucket surface by dust absorption fan, the ash of dust-absorbing filtering bucket after the work of a period of time
It can become very thick, the pick-up performance for influenceing dust absorption fan causes car to produce airborne dust；By shake dirt motor by chain drive, drive
Dust-absorbing filtering bucket rotates, and scraper plate is arranged on fixed, the scraper plate when dust-absorbing filtering bucket rotates of bottom in main brush box body rear
The scraps of paper of dust-absorbing filtering bucket are scraped, the dust on dust-absorbing filtering bucket surface is scraped and fallen into the dustbin of bottom；Meeting when side brush rotates
The dust on ground is kicked up into generation airborne dust, the water smoke that shower nozzle sprays plays depositing dust effect；Push rod drives main brush lifting rod to provoke
Main brush box body swings up and down the lifting for realizing main brush box body around lifting rotation point.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as employ the present invention design and technical scheme carry out various unsubstantialities improvement, or it is not improved will
The design and technical scheme of the present invention directly applies to other occasions, within protection scope of the present invention.
