Abstract
The utility model discloses a vacuum suction inlet device of a sweeping machine, which is characterized in that a suction inlet is a rectangular inlet and a transitional coupling is arranged between the rectangular inlet and a wind sucking pipe. The suction inlet end is provided with a front wing plate and a back wing plate, and transitional connection plates are arranged among the front wing plate, the back wing plate and the outer side of the suction inlet. Side baffle plates are arranged outside the front wing plate, the back wing plate and the transitional connection plates. The utility model has the advantages that the sucking and sweeping speed of the suction inlet with the wing plates is enhanced by two to three times than that of the suction inlet without the wing plates under the condition that the power of a fan and the distance between the suction inlet and the ground are same. The power of the suction inlet with the wing plates is saved by 50% to 75% that of the suction inlet without the wing plates under the condition that the sucking and sweeping speed and the distance between the suction inlet and the ground are not changed.
Description
The utility model relates to the suction mouth device of the suction apparatus of municipal highway road-sweeper, particularly highway sweeper.
Along with the development that urban modernization is built, large high-speed highway, urban interchange and broad smooth asphalt surface extend rapidly, and road surface cleaning and dust alleviation work are more and more heavier.Because pavement cleaning vehicle can improve China's environmental sanitation machinery level greatly, so market prospects are wide.
Vacuum sweeper has advantages such as operating rate height, environment pollution be little, is the developing direction of current pavement cleaning vehicle.And the vacuum pressure conveying device is the important device of vacuum sweeper, and it is one of key index of road-sweeper that the operating efficiency of device is sent in suction.Through investigating, some the road-sweeper clean absorption rates in using at present are lower, can produce the not rubbish band of exhaustion on road-sweeper ground later, and structure and shape that its generation reason is a sucking hole device are unreasonable, directly influence the operating efficiency of road-sweeper.
The homemade road-sweeper that for example has adopts single blower fan circulating-dedusting system, and the turbulent suction nozzle of middle branch also disposes two side brushes, utilizes and inhales the operating principle of sweeping combined type.Blower fan is driven by assistant engine, and the high velocity air of generation forms stronger negative pressure (vacuum) at the dust absorption nozzle seal area, makes the air-flow of carrying rubbish and dust secretly through dust absorption nozzle, and dust sucting pipeline enters the dust fall case.Wherein divide turbulent technology, in blow double suction, the suction inlet place has designed an air-flow anti-blowpipe, purpose is to make the part air-flow draw go back to ground, strengthens flow perturbation, and the rubbish that is attached to the ground recess is floated, and is convenient to be collected by suction inlet.But because suction inlet only is a simple cylinder, the air-flow skewness, suction inlet place air velocity height is then lower between two suction inlets.In actual use, it is neat and tidy that near the rubbish the suction inlet is inhaled, and occurred one and do not clean clean rubbish band between two suction inlets.
In order to address this problem, improve to inhale and sweep efficient and energy conservation, improve three hole sucking hole devices, and the purpose of this utility model provides a kind of novel road-sweeper suction mouth device.
Road-sweeper suction mouth device, the aspiration channel of its road-sweeper is connected with suction inlet, it is characterized in that: described suction inlet is a rectangular opening, being provided with transition between rectangular opening and the aspiration channel is connected, be provided with forward and backward wing plate at aspiration port, between the forward and backward wing plate and the suction inlet outside, transition connecting plate is arranged, be provided with side shield at the forward and backward wing plate and the transition connecting plate outside.
The design is through contrast test, and its superiority is very obvious:
1), under power of fan and the suction inlet condition identical apart from ground level, have the wing plate suction inlet to sweep 2～3 times of speed raisings than the suction of no wing plate suction inlet;
2), sweep under the condition that speed and suction inlet remain unchanged apart from ground level, the wing plate suction inlet is arranged than no wing plate suction inlet saving power 50%～75% when suction.
