Description

Blowing and sucking road sweeper

Affiliated technical field:

The present invention relates to a kind of blowing and sucking road sweeper, it is to aim at a kind of special environment protection equipment that cleans the road surface and design.

Background technology:

Existing road surface cleaning device, its main body are that the broom of two (or four) trumpet types vertically is buckled on the ground, and fast to revolving, dust kicked up to be absorbed filter dirt by dust catcher again and reach the purpose of cleaning floor.But because of the shortcoming of its structure and working method, weak point just obviously manifests: 1. density (proportion) sand grains and stone etc. more greatly is difficult to sweep receipts; 2. airborne dust is big, and secondary pollution is serious; 3. power consumption is big, and the cost height is difficult for popularizing.

The purpose of invention:

Purpose of design of the present invention is: make its good working effect, no reentrainment of dust pollutes, and simple in structure, with low cost, and power consumption is little.

Technical scheme:

In order to achieve the above object, following design scheme is now proposed:

In the middle and lower part of a motor-driven carriage, a horizontal drum is set.Two ends and drum at drum are installed two disk wheels that radius is bigger with one heart.Wheel can roll forward with car along contacting to earth.Have certain intensity that the so-called collection sheet that picks up of favorable elasticity is arranged again along tangent line to fixing some uniformly at interval around drum, its breadth wise dimension and drum are isometric, and its vertical tangent plane is similar Shape.When drum rolls forward with car, its

The lateral part of shape can be touched in turn and be pasted ground, its vertical part then with ground become to dehisce forward acute angle.

In the back of drum vacuum noz(zle) and blowing nozzle are set, its breadth wise dimension and drum are isometric.Blowing nozzle is close to the back lower place of vacuum noz(zle) with certain radian, and opening is towards the front lower place.

Take out pressure fan and dedusting dustbin (assembly of deduster and rubbish storage bin) in the setting of the top of car.

With admission pipe the air inlet port of the top of vacuum noz(zle) with the dedusting dustbin is connected, with exhaust tube the gas outlet of dedusting dustbin with take out the pressure fan air inlet port and link, the gas outlet that will take out pressure fan with gas blow pipe is connected with blowing nozzle.

Under the driving of motor, when drum rolls forward with car, to take out pressure fan and keep watch by gas blow pipe, blowing nozzle and blow to ground, the dust of kicking up, the scraps of paper and leaf blow sandstone etc.The dust of kicking up is sucked by vacuum noz(zle) with air-flow and enters the dedusting of dedusting dustbin by admission pipe.The air communication of removing dirt is crossed exhaust tube and is entered and take out pressure fan, finishes a working cycles.

The sand reservoir box of cuboid is set in the front lower place of drum, isometric with drum.Opening makes progress, and under the situation that does not influence the drum rotation, the two is close as much as possible.Blowing nozzle blows sandstone etc. forward, is picked up the collection sheet and touches the lateral part of pasting ground and collect, and is changeed band by drum again and tumbling in the sand reservoir box in the place ahead.

With dustproof case blowing nozzle, vacuum noz(zle), drum, sand reservoir box all cover wherein make it to surround a comparatively space of sealing jointly, to prevent to be blown the excessive contaminated environment of kicking up of dust with ground.Excessive for preventing dust better, can open the venthole of an adjustable size in the gas blow pipe stage casing, and communicate with atmosphere by small-sized dirt catcher.

Beneficial effect:

Adopt above-mentioned design scheme, can make not only that the present invention is simple in structure, with low cost, power consumption is little, good working effect, no reentrainment of dust pollutes, and friction is also less over the ground.So it is low that the present invention also has fault rate, characteristics such as parts long service life.

The drawing explanation:

The invention will be further described below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present invention

Fig. 2 is drum and the structural representation that picks up the collection sheet

Wherein: 1. driver's seat; 2. take out pressure fan; 3. gas blow pipe; 4. complete machine trailing wheel; 5. case; 6. vacuum noz(zle); 7. blowing nozzle; 8. drum; 9. sand reservoir box; 10. complete machine front-wheel; 11. dedusting dustbin; 12. exhaust tube; 13. admission pipe.

Realize the best way of invention:

As Fig. 1, the drum 8 of yardsticks such as a transverse width and overall width is set in the middle and lower part of a motor-driven carriage.At the thin as far as possible so-called disk wheel of concentric two thickness of installation of two ends of drum.Enclose set soft rubber band around the wheel.The lower edge of wheel lands, and drum can be rolled forward with car.

Above-mentioned two disks wheel, one of them and drum 8 are connected, another then can rotate relative to drum, like this drum just can be neatly with the car right-hand rotation of turning left.

Around drum 8, along tangent line to, at interval fixing some (6-8 sheets) uniformly has certain intensity that the so-called collection sheet that picks up of favorable elasticity is arranged again.Its transverse width and cylinder are isometric, and its vertical section is

Shape, only its angle anyhow is not 90 ° but about 130 °.When drum 8 rolled forward with car, these lateral parts of picking up the collection sheet can be touched in turn and be pasted ground, and vertical part becomes the acute angle about 50 ° with ground, dehisce forward.

Pick up the available wide 4cm of collection sheet, thick 1mm, the good steel bar of elasticity is done skeleton, the thick rubber film of middle subsidy 3mm, and to make these rubber films grow skeleton 8～10cm.We are called soft tongue to this part that grows, and gravity can make soft tongue generation bending by a relatively large margin.So just can prolong each and pick up the time that the collection sheet touches subsides ground, blow with more effective collection and roll next sandstone etc.

The diameter of drum 8 is decided to be 65～70cm, and then to be decided to be 1m better for the diameter of disk wheel.

In the back of drum 8 vacuum noz(zle) 6 is set as Fig. 1, opening is towards the front lower place, and be close to thereafter be blowing nozzle 7, and arc-shaped bend stretches to the front lower place of vacuum noz(zle) 6.Mouth end distance ground 5cm makes the air-flow that blows out become angle about 30 ° towards the front lower place and with ground.

The opening of vacuum noz(zle) 6 is broad as much as possible, so as can inspiration larger-size tablet, as leaf etc.And the opening of blowing nozzle 7 will be narrow as far as possible narrow (1～1.5cm), the air-flow that blows to ground is concentrated, at a high speed and high pressure (1kpa) make it not only will kick up more up hill and dale the dust and the scraps of paper, also want to blow bigger stone of proportion (density) and sand grains etc.

Form the high pressure draught about above-mentioned 1kpa, the pressure fan of taking out of high rotating speed (3000 rev/mins) will be arranged.As Fig. 1, the pressure fan 2 of taking out at a high speed is arranged on the latter half of top of car, above the first half of car so-called dedusting dustbin 11 is being set then, i.e. the assembly of deduster and dustbin (having multiple mature technology, the narration of being omitted here).

With admission pipe 13 air inlet port of vacuum noz(zle) 6 with dedusting dustbin 11 is connected.

With exhaust tube 12 gas outlet of dedusting dustbin is connected with the air entry of taking out pressure fan 2.

With gas blow pipe 3 gas outlet of taking out pressure fan 2 is connected with blowing nozzle 7.

Sand reservoir box 9 openings that cuboid is set in the place ahead of drum 8 are upwards isometric with drum.

Ground sand grains finger stones etc. are blown forward by the high speed and high pressure air-flow, then are stranded in picking up on the collection sheet of contacting to earth, and the back is changeed by drum 8 and taken the front to and tumble into and store in the sand reservoir box 9 again.

The steel sheet that sand reservoir box 9 usefulness plastic plates or 1mm are thick is made.Its specification is suitable with installing with following standard, promptly picked up collect sheet and change and be with the sandstone of coming etc. can tumble smoothly in the inlet body, at the bottom of the case apart from ground 10cm height.

Case 5 is used for preventing dust.Vacuum noz(zle) 6, blowing nozzle 7, drum 8, sand reservoir box 9 all are placed in one.

The near-earth of case 5 is along distance ground 10cm.This near-earth along last more fixedly the rubber film enclose to connect and mop floor.Like this, case 5, rubber film, ground three have just surrounded a comparatively space of sealing.

To sum up state as can be seen, the air-flow that blowing nozzle 7 blows out is a closed cycle air-flow, so the inside and outside of case 5 can not form pressure differential, the dust that blowing kicks up comes also just is difficult to excessive, can not cause reentrainment of dust to pollute.Certainly this is an ideal situation, for safer, can make and form certain negative pressure in the case.The size of this negative pressure has or not and can be determined on a case-by-case basis it by the operator.Technical measures are: the gas outlet of opening an adjustable size in the stage casing of gas blow pipe 3, and communicate with atmosphere by a small-sized worry dirt device.Blow into and suck the tolerance balance no longer in the case 5 like this, will form our needed negative pressure.

The rotating shaft of drum is by the left and right side supporting of case.

Through experiment showed, that deduster selects the Wet-type centrifugal dedusting for use, 1.2～1.3 meters of cleaning width, pace 5～8 kms/hour, power consumption then of the present invention will be no more than 5KW (theoretical calculating is 3.1KW).
