After road-sweeper moves with high speed, suction nozzle to the action time of same place sand and dust, rubbish with the increase of running speed minimizing in proportion, what the effect of sand and dust, waste layer successively being adsorbed from sand and dust, waste layer surface from existing suction nozzle was different is, the present invention is according to the characteristic of gas flow and rule adopts many suction inlets and by suction inlet position reasonable layout, the structure of coaming plate 2, front apron 3, interval dividing plate 5 combines and makes γ-ray emission swirling flow simultaneously, entrainments effect thereby realize.Suction nozzle has been strengthened the entrainment effect of suction nozzle to sand and dust, rubbish, has the huge husky ability of taking just as the air-flow of cyclone, and thick sand and dust, rubbish, dust layer are kicked up from the bottom, moves in suction inlet and by suction pipe and sucks with the extremely short time.
Suction nozzle of the present invention adopts durable wear-resisting and have a front apron 3 of excellent toughness in suction nozzle front.Front apron 3 has following several benefit: the ground clearance of the below air inlet port while having reduced suction nozzle work, front apron 3 ground clearances are controlled at 4mm-8mm, thereby strengthen air velocity, make to peel off sand and dust, waste layer surface, and can be penetrated into sand and dust, waste layer bottom, sand and dust, waste layer are kicked up.Front apron 3 adopts duplex circular arc (two spaced apart spill sections 301), the front apron 3 of circular arc has changed the direction that is entered suction nozzle by air-flow, with match in the interval dividing plate 5 of coaming plate 2 contraction sections, air-flow is divided into multi beam from suction nozzle surrounding and moves in suction nozzle, facilitate suction nozzle to sand and dust, rubbish entrainment effect, air-flow is to sand and dust, the effect of rubbish multi-angle, form huge whirlpool, just as cyclone by thick sand and dust, waste layer sand and dust, rubbish moves up from the bottom, enter the sand and dust of each suction inlet, the each self-interaction of rubbish air-flow, make sand and dust, rubbish and sand and dust, rubbish has obtained abundant mixing, sand and dust are strengthened, the air-flow followability of rubbish, most of sand and dust, rubbish, sand and dust, rubbish is drawn in two main suction inlets 4 smoothly.Recess in the spill section 301 of front apron 3 is provided with elasticity hyoplastron, elasticity hyoplastron is made up of elasticity nonmetals, and when work, elasticity hyoplastron is to flexural deformation in suction nozzle, the ground clearance of elasticity hyoplastron is controlled at 7mm-12mm, for large volume sand and dust and rubbish by the suction nozzle inner chamber that enters here.
Suction nozzle of the present invention arranges three suction inlets, and two main suction inlets 4 and 6, two main suction inlets 4 of an auxiliary suction inlet are side by side in suction nozzle front end, and rear end arranges an auxiliary suction inlet 6.Being arranged so that of preposition two main suction inlets 4 all forms more uniform negative pressure in nozzle body ante-chamber (main vacuum chamber) and back cavity (auxiliary vacuum chamber), two main suction inlet 4 suction operation independent of one another mutually cross actions, make suction nozzle only need lower raise into wind speed and sand and dust, rubbish, sand and dust, waste layer all can be risen and move up.The arranging of auxiliary suction inlet 6 extended the adsorption time of suction nozzle to sand and dust and rubbish, sand and dust, rubbish, the suction that enough stronger action time is beneficial to sand and dust and waste layer is picked up, be not adsorbed clean sand and dust, rubbish by assisting suction inlet 6 to obtain the effect of mending suction for two main suction inlets 4.Because the interval dividing plate 5 below air velocities that are arranged so that of interval dividing plate 5 sharply increase, auxiliary suction inlet 6 places form again entrainments effect, and sand and dust and rubbish are by thoroughly absorption is clean.
Two main suction inlets 4 are positioned at front apron 3 left and right sides, with suction nozzle foremost distance be controlled at 25cm-35cm, the recess mid point of the spill section 301 of two corresponding front aprons 3 in main suction inlet 4 centers.Auxiliary suction inlet 6 is positioned on suction nozzle center line.The distance of the coaming plate 2 of the Edge Distance suction nozzle end of auxiliary suction inlet 6 is 3cm-7cm; Two preposition main suction inlets 4 are as the main suction inlet of suction nozzle, and most of sand and dust and rubbish can enter in total suction pipe 7 by it.Auxiliary suction inlet 6 can be effective, inhales the residual sand and dust, the rubbish that pick up two preposition main suction inlet 4 middle-ends.Pick up effect for the suction that ensures suction nozzle, ensure negative pressure intensity in suction nozzle, at setting area, suction nozzle middle part space bar 5, suction nozzle is divided into ante-chamber (main vacuum chamber) and two chambeies of back cavity (auxiliary vacuum chamber).The caliber size difference of two main suction inlets 4 and an auxiliary suction inlet 6, so just makes ante-chamber negative pressure much smaller than back cavity negative pressure, and sand and dust, rubbish major part have completed absorption at ante-chamber.Because high velocity sweep running speed is high, after premenstrual two suction inlets, in suction nozzle mid line region, understand some sand and dust, rubbish because horizontal velocity is too high and do not caught by suction, the 3rd suction inlet arranging greatly lengthens the suction of sand and dust and rubbish and picks up distance, extend the adsorption time of sand and dust, rubbish, strengthen suction nozzle and inhaled the ability of picking up sand and dust and rubbish, can will adsorb clean apart from sand and dust, rubbish.
Interval dividing plate 5 is arranged on the front contraction section end of coaming plate 2, and suction nozzle has been divided into former and later two chambeies by interval dividing plate 5, interval dividing plate 5 the Negative Pressure Difference that has ensured suction nozzle ante-chamber and back cavity is set, ante-chamber remains on high negative pressure, back cavity remains on and is slightly less than ambient pressure; Most of sand and dust, rubbish are adsorbed totally at ante-chamber; Demarcation strip ground clearance is simultaneously less, and the bottom sand and dust, the waste layer particle that are not started yet through ante-chamber are risen and move up due to the violent increase of demarcation strip below air velocity, are assisted suction inlet 6 to be drawn in total suction pipe 7.Interval dividing plate 5 shapes are as shown in Fig. 1,2,4 and 5, middle is to suction nozzle rear recess, the shape of interval dividing plate 5 changes sand and dust, the rubbish airflow direction of coming from glue chamber again, it is more abundant that the air-flow interaction of multi-angle is mixed to get sand and dust and air-flow, air-flow followability further strengthens, and residual sand and dust particle is adsorbed by auxiliary suction inlet 6 eventually.
The form that suction nozzle dividing plate of the present invention adopts anterior contraction, middle part expansion, rear portion to shrink,
Disc type vacuum chamber is divided into two sections by interval dividing plate 5, uses ante-chamber (main vacuum chamber) and back cavity (auxiliary dust suction) to represent herein.The regular inside contraction of ante-chamber front end, on the one hand by air-flow small loss to suction inlet place water conservancy diversion, on the other hand, offset due to the impact of running speed on sand and dust, rubbish speed, the air-flow entering from suction nozzle both sides is still collected to suction inlet.Regular contraction after the small size expansion of back cavity front end.Ante-chamber not by suction nozzle adsorb clean sand and dust, rubbish has very large horizontal velocity after entering back cavity, this part sand and dust, rubbish horizontal velocity buffering in back cavity expansion segment reduces, sand and dust, rubbish air-flow fully mix, air-flow followability further strengthens, due to the reduction of sand and dust, rubbish air-flow, suction nozzle has lengthened the action time to sand and dust, rubbish, and remaining sand and dust, rubbish are adsorbed clean under the effect of auxiliary suction inlet 6; The regular inside contraction in rear end, by air-flow small loss to auxiliary suction inlet 6 place's water conservancy diversion, and offset due to the impact of running speed on sand and dust, rubbish speed, the air-flow entering everywhere from suction nozzle is still collected to auxiliary suction inlet 6, strengthened the action effect that entrainments of air-flow, thereby ability is picked up in the suction of enhancing suction nozzle.
After fan starting, form high negative pressure in nozzle body, around air-flow moves to suction nozzle, and the sand and dust and the rubbish that are positioned at nozzle body surrounding also move to suction nozzle under the effect of air-flow.Because this suction nozzle front apron 3 is made up of three circle-arc tooth structures, it is very high that air-flow enters speed in nozzle body, facilitate the entrainment effect of suction nozzle air-flow to sand and dust, rubbish, two main suction inlets 4 are just as two high negative pressure centers, and high velocity air has the huge husky ability of taking, sand bed is kicked up from bottom, air-flow at a high speed entrainments sand and dust, rubbish two main suction inlets 4 of suction nozzle fast, the whirlpool sinuous flow that air-flow forms in nozzle body ante-chamber (main vacuum chamber), sand and dust, rubbish enter after fully mixing in two main suction inlets 4, are sucked in suction pipe through total suction pipe 7.After suction nozzle ante-chamber (main vacuum chamber), may be still can some sand and dust, rubbish kicked up by starting not yet, due to the structure design of the coaming plate 2 of arc and the interval dividing plate 5 of arc, air-flow is accelerated again, remaining sand and dust, rubbish are started again to be kicked up, air-flow again forms and once entrainments effect herein, and sand and dust, rubbish are adsorbed onto in nozzle body rapidly; After ante-chamber (main vacuum chamber), near suction nozzle center line, also have a part of sand and dust, rubbish is higher to the horizontal momentum of backlash, concentrate on zone line, interval dividing plate 5 coordinates coaming plate 2 to form an extended buffer area at back cavity (auxiliary vacuum chamber) front end, Ci district air velocity decreases, sand and dust, rubbish air-flow are mixed to get more abundant, under the effect of suction inlet, multi beam air-flow interacts, come by front do not adsorb clean sand and dust, rubbish is assisted suction inlet 6 to absorb completely, adsorbs clean target thereby reached.Empirical tests is analyzed, and under equal operating condition, suction nozzle of the present invention can be increased to running speed more than one times, has increased substantially operating speed and the sweeping efficiency of road-sweeper.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
