Description
Technical field
The present invention relates to environmental sanitation field of mechanical technique, more particularly to a kind of sweeper nozzle structure and sweeper.
Background technology
Pavement garbage is delivered near nozzle structure by sweeper by brush and nozzle in the course of the work, is being centrifuged
Under the swabbing action of blower fan, the mixture for being mingled with rubbish and water is entered in the garbage collection box of sweeper by nozzle structure,
Complete the cleaning process of pavement garbage.Key operation part of the nozzle structure as sweeper, its structure type directly influence
The sweeping efficiency and operation effectiveness of sweeper.
Nozzle structure generally comprises suction inlet, suction pipe and transition structure at present, and suction pipe and transition structure are general all perpendicular to ground
Face is arranged, higher and non-adjustable from the ground, and transition structure volume and changes of section gradient are bigger than normal.
The problem of said structure is present be：1) it is bigger than normal not perpendicular to ground to easily cause gas-flow resistance for suction pipe and transition structure
Suction beneficial to rubbish is picked up；2) nozzle structure terrain clearance is high, and suction nozzle cavity volume is larger, and its internal negative pressure variable gradient is big, right
The suction on ground is weaker, is unfavorable for the suction to ground small garbage particle and picks up；3) transition structure volume and changes of section gradient are inclined
The big suction nozzle cavity inside Velocity Profiles that easily cause are uneven, many low speed and eddy region be present, are unfavorable for rubbish
Suction is picked up.
Because ground refuse is based on fine sand gravel, rubble grain, dust in equal volume smaller, particle that density is larger, such rubbish
The cleaning of rubbish particle generally requires very big suction, and this requires that the negative pressure in suction nozzle cavity is high and gradient is small, therefore, can examine
Considering reduces the terrain clearance of suction pipe and transition structure.
The suction pipe and transition structure of existing nozzle structure are directly welded on suction nozzle main body, and its terrain clearance keeps constant,
The terrain clearance of suction pipe and transition structure can not be adjusted according to ground granulated garbage flexible in size, energy is picked up in the suction that have impact on suction nozzle
Power.
Therefore, how to make that suction nozzle cavity inside gas-flow resistance is small, low speed and eddy region are few, Velocity Profiles are equal
Even, negative pressure is high and variable gradient is small, can either ensure that nozzle structure provides powerful suction, and can for ground small garbage particle
The rubbish thing for enough making volume larger passes through, and has the function that to the sweeping efficiency for lifting sweeper positive.

Very little three times no more than the size connected with suction pipe 21, the changes of section gradient of transition structure 22 can be reduced suitably, therefore, be had
Beneficial to making, the Velocity Profiles of suction nozzle cavity inside are uniform, reduce low speed and eddy region, the suction beneficial to rubbish are picked up.
One preferably or in alternative embodiment, vertical (direction along between the suction pipe 21 and suction inlet) section of transition structure 22
Can be with trapezoidal, the first opening of transition structure 22 connects with suction inlet, and the second opening of transition structure 22 connects with suction pipe 21, and
Because suction pipe 21 is circular port, the second opening of transition structure 22 is square orifice, to realize the connection of square orifice and circular port, the
Two openings and the junction of circular port are additionally provided with rebound 23, to prevent the junction of square orifice and circular port from leaking out.First opens
The size of mouth is more than the size of the second opening, and the long side of the first opening is no more than three times of the diameter of suction pipe 21, reaches and reduced
Cross the purpose of the volume of structure 22 and changes of section gradient.
Above-mentioned preferably or in alternative embodiment, transition structure 22 can include the first trapezoidal plate, the second trapezoidal plate, first
Square plate and the second square plate, wherein, the first trapezoidal plate and the second trapezoidal plate are arranged in parallel, and the first trapezoidal plate is close to sucker 1
First baffle 11, second baffle 12 of second trapezoidal plate close to sucker.
It can be tilted as shown in figure 3, transition structure 22 is overall to the direction of second baffle 12 of sucker 1, from the side of sweeper
To seeing, preferably 10 °~20 ° of the angular range of the first trapezoidal plate and the second trapezoidal plate of transition structure 22 and the acute angle of top plate 15,
Reach suction pipe 21 and purpose that transition structure 22 is obliquely installed.
For the embodiment of the present invention by the way that suction pipe 21 and transition structure 22 are in tilted layout, suction pipe 21 is in similar to Venturi tube
Shape, and transition structure 22 is overall trapezoidal, and the size that transition structure 22 connects with suction inlet is no more than what is connected with suction pipe 21
Three times of size, relative to existing transition structure, the volume and changes of section gradient of transition structure are reduced, reduces air-flow resistance
Power, and reduce low velocity eddy region, more smooth, the overall wind speed raising in the inside of sucker 1 is caused air flow through, while in sucker 1
Portion's velocity uniformity improves, and the variable gradient of speed reduces, and helps to reduce the grit holdup time, when the speed of sweeper becomes big
When rubbish omit phenomenon and reduce, the suction for effectively improving sweeper picks up performance.
As shown in figure 3, one preferably or in alternative embodiment, in order to coordinate with the neck 18 set in suction nozzle cavity, inhale
The connector set in tube assembly 2 can be the part that the second trapezoidal plate of transition structure 22 extends downwardly, the second trapezoidal plate
Extension extends to suction nozzle cavity inside, and inserts in the neck 18 of suction nozzle cavity.Neck 18 is obliquely installed, transition knot
Second trapezoidal plate of structure 22 can move up and down along the incline direction of neck 18.
As shown in figure 4, second baffle 12, which can include the square tube 121 on top, the wearing plate 122 of bottom and rear side, plays fixation
The riser 123 of effect, the road clearance of wearing plate 122 are consistent with the road clearance of the first side plate 13 and the second side plate 14.It is wear-resisting
Plate 122 can be made of elastomeric material.Neck 18 can be connected with the top square tube 121 of second baffle 12.
In above-described embodiment, sucker 1 can include flexible board, and suction inlet is located at flexible board, and flexible board can be with suction pipe assembly 2
Movement and deform.Above-mentioned flexible board namely surrounds the top plate 15 of suction nozzle cavity.
One preferably or in alternative embodiment, top plate 15 can be combined by multi-sheets.
As shown in figure 5, top plate 15 is polylith combined type flexible plate, it is with the sucker 1 with two suction pipe assemblies 2 below
Example, is illustrated to the concrete structure of top plate 15.
Top plate 15 combines to be formed by five blocks of plates, is respectively：The first plate 151 between two suction pipe assemblies 2, two suction pipes
Component 2 each corresponding and the second plate 152 and the 3rd plate 153 between the first side plate 13 and the second side plate 14 of sucker 1, and two
Respective the 4th plate 154 and the 5th plate 155 between the first baffle 11 of sucker 1 of individual suction pipe assembly 2.When oil cylinder 31 drives suction pipe
When component 2 moves down, suction inlet terrain clearance reduces, and can improve suction and pick up ability, top plate 15 produces plastic deformation therewith, simultaneously
The apex height of the front left side of sucker 1 and forward right side is constant, will not only air leakage phenomena occur but also not interfere with the curved of first baffle 11
Bent situation, granulated garbage is not influenceed suction nozzle cavity is entered by first baffle 11.
