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, represents with ante-chamber (main vacuum chamber) and back cavity (auxiliary dust suction) herein.The regular inside contraction in ante-chamber front end, on the one hand by air-flow small loss to suction inlet place water conservancy diversion, on the other hand, counteract because running speed is on the impact of sand and dust, rubbish speed, the air-flow entered from suction nozzle both sides still collected to suction inlet.Regular contraction after the expansion that back cavity front end is small size.Ante-chamber is not had very large horizontal velocity by the clean sand and dust of suction, rubbish 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 strengthens further, due to the reduction of sand and dust, rubbish air-flow, suction nozzle increases the action time to sand and dust, rubbish, and remaining sand and dust, rubbish are clean by absorption 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 water conservancy diversion, and counteract because running speed is on the impact of sand and dust, rubbish speed, the air-flow entered everywhere from suction nozzle is still collected to auxiliary suction inlet 6, enhance the Involving velocity effect of air-flow, thus ability is picked up in the suction strengthening suction nozzle.
After fan starting, form high negative pressure in nozzle body, surrounding 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, the speed that air-flow enters in nozzle body is very high, facilitate suction nozzle air-flow to sand and dust, rubbish entrainment effect, two main suction inlets 4 are just as two high negative pressure centers, and high velocity air has and huge takes husky ability, sand bed is kicked up from bottom, sand and dust, rubbish are entrainmented two main suction inlets 4 of suction nozzle by air-flow at a high speed fast, the whirlpool sinuous flow that air-flow is formed in nozzle body ante-chamber (main vacuum chamber), enter after sand and dust, rubbish fully mix in two main suction inlets 4, be sucked in suction pipe through total suction pipe 7.After suction nozzle ante-chamber (main vacuum chamber), may still can some sand and dust, rubbish be 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 is again formed herein and once entrainments effect, and sand and dust, rubbish are adsorbed onto in nozzle body rapidly; After ante-chamber (main vacuum chamber), also have a part of sand and dust at suction nozzle approximate centerline, rubbish is higher to the horizontal momentum of backlash, concentrate on zone line, interval dividing plate 5 coordinates coaming plate 2 to define an extended buffer area in back cavity (auxiliary vacuum chamber) front end, decrease in this district's air velocity, sand and dust, rubbish air-flow are mixed to get more abundant, under the effect of suction inlet, multi beam air-flow interacts, by front come do not adsorb clean sand and dust, rubbish assisted suction inlet 6 to absorb completely, thus reaches the clean target of absorption.Empirical tests is analyzed, and under equal operating condition, running speed can be increased to more than one times by suction nozzle of the present invention, 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 done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
