Abstract
The present invention discloses a suction nozzle for sweeping a road, which comprises a body of a suction nozzle and side wheels arranged on both sides of the body of a suction nozzle, wherein the front end and the back end of the body of a suction nozzle along the advance direction of the body of a suction nozzle are respectively provided with a front-end plate and a back-end plate; the top of the body of a suction nozzle is provided with a reverse-blowing air pipe connected with an outlet of a blower and a suction pipe connected with an inlet of a refuse box; a side reverse blower is arranged between a reverse air-blowing pipe in the body of a suction body and a side plate adjacent to the reverse air-blowing pipe, and a front reverse blower is obliquely arranged between the reverse air-blowing pipe and the front-end plate; one end of the front reverse blower is connected with the side plate of the body of a suction nozzle, and the other end is connected with the suction pipe; the closer distance between the front reverse blower and the suction pipe, the farther distance between the front reverse blower and the front-end plate; a bottom plate of the body of a suction nozzle is provided with an air outlet corresponding to the front reverse blower. The present invention is a suction nozzle for sweeping a road, which can generate directive high-speed gases to roll up garbage tightly attached to a road surface and to push the garbage towards the suction pipe so as to improve the integral capability of cleaning the garbage.
Description
Technical field
The present invention is mainly concerned with the road-cleaning apparatus field, refers in particular to a kind of suction nozzle that is used for road-cleaning.
Background technology
In the prior art,, sweeping machine can be divided into two kinds of wet type sweeping machine and dry type sweeping machines according to the operating type of sweeping machine.Wherein, the wet type sweeping machine adopts to inhale sweeps combination, wet type depositing dust, and it has characteristics such as simple in structure, easy to operate.During cleaning work, play ash, constantly spray water earthward with in the brush in order to prevent airborne dust.On the more road surface of rubbish dirt scholar, the injection flow rate deficiency, the dirt scholar can be flown upward everywhere, sticking easily stifled suction pipe; It is excessive to spray water, and not only causes water waste, and the dirt scholar mixed mud, and mud has adhered on the ground, waits water one to do, and dust waves again in the same old way everywhere.At present, the domestic sweeping machine that generally uses is still inhaled the wet type sweeping machine of sweeping combination, wet type depositing dust.The dry type sweeping machine need not be sprayed water when cleaning work, is applicable to avenue, speedway, airport, harbour etc., is particularly suitable for that lack of water, drying, dust storm are big, the algid stage of freezing grow the area use of (north of china in winter).It adopts multistage environmental protection dedusting technology, can thoroughly remove the dust rubbish thing on the road surface.In China, it still is in the initial stage developing stage.All be connected with nozzle unit on the sweeping machine of these two kinds of forms, rubbish on the road surface is at first swept to the dead ahead of suction nozzle by the cleaning agency on the sweeping machine with it, near the negative pressure that produces suction pipe by blower fan is adsorbed rubbish then, makes dusty gas and rubbish suck the air draught road in the lump in dustbin.In this adsorption process, the big or bigger rubbish of adhesive force is difficult to be sucked in the dustbin by blower fan for quality.Therefore in the prior art, in nozzle body, be provided with the preceding blowback vertical, and offer the preceding blowback corresponding air outlet vertical with this in the bottom of nozzle body with the sweeping machine direction of advance.When the sweeping machine operation, the air-flow that blower fan produces blows afloat rubbish and the dust that is attached at ground then along with preceding blowback and air outlet blow out along the direction of advance of sweeping machine, and it is sucked from suction pipe easily.But, this vertically arranged before the shortcoming of blowback be: 1, the high velocity air that blows out of preceding blowback is that direction of advance towards suction nozzle blows out, and suction pipe generally is arranged on the side of suction nozzle, therefore a large amount of from suction pipe rubbish far away and fail to be sucked by suction pipe, the cleaning effect of suction nozzle integral body is affected; 2, the high velocity air that blows out of preceding blowback will produce a large amount of dust, cause reentrainment of dust, pollute the ambient air environment.
Summary of the invention
The technical problem to be solved in the present invention just is: at the technical problem of prior art existence, the present invention proposes a kind ofly can produce directive high-speed gas and make the rubbish of being close to the road surface roll and push to suction pipe, thereby improves the suction nozzle that is used for road-cleaning of its whole junk-free ability.
In order to solve the problems of the technologies described above, the solution that the present invention proposes is: a kind of suction nozzle that is used for road-cleaning, it comprises nozzle body and is installed on the side wheel of nozzle body both sides, rear and front end on the direction of advance nozzle body of nozzle body is respectively front end-plate and end plate, the top of nozzle body is equiped with and blower fan outlet reverse-blow pipe that links to each other and the suction pipe that links to each other with the dustbin import, be provided with the side blowback between reverse-blow pipe and the adjacent side plates in the nozzle body, it is characterized in that: tilting between reverse-blow pipe in the described nozzle body and the front end-plate have a preceding blowback, an end of blowback links to each other with the side plate of nozzle body before being somebody's turn to do, the other end links to each other with suction pipe, and the distance between suction pipe blowback more nearby and front end-plate is just far away more; Offer the air outlet corresponding on the base plate of described nozzle body with preceding blowback.
Blowback comprises Crashworthy plate, front flow guiding plate, back front flow guiding plate, middle deflector, top board and base plate before described, Crashworthy plate and front flow guiding plate are connected on the top board, middle deflector and back front flow guiding plate are connected on the base plate, form the α angle between top board and the front flow guiding plate.
The α angle that described top board and front flow guiding plate form is 35～75 °.
Compared with prior art, the invention has the advantages that:
1, the present invention is used for the preceding blowback that is obliquely installed in the suction nozzle of road-cleaning, distance between suction pipe blowback more nearby and front end-plate is just far away more, thisly be obliquely installed high velocity air that the air outlet that makes in the past blowback and suction nozzle bottom blows out and produce incline direction wind-force along preceding blowback, to roll up to the suction pipe place from suction pipe far rubbish and dust, the disadvantage of having avoided suction pipe can't thoroughly clear up distant place rubbish has improved whole junk-free effect;
2, the present invention is used for forming the α angle between the top board of suction nozzle of road-cleaning and the front flow guiding plate, it is all rolled-up that particularly the air-flow that is produced when this α angle is 35～75 ° can make the rubbish of the rubbish of being close to the road surface and big quality effectively, strengthened the assimilation effect of suction pipe, simultaneously, the swabbing action of blowback air-flow can make the pure air ecto-entad flow, form dustproof air curtain, thereby in the time of can avoiding suction nozzle in working order, cause whole road surface to form the situation of a large amount of airborne dusts, make the junk-free effect reach optimum state;
3, the present invention's suction nozzle of being used for road-cleaning not only can use separately, and can be used in combination with brush and finish cleaning work jointly, and its highly versatile is applied widely.
