[0031] FIG。 3 illustrates an exploded view, and FIG。 4 illustrates an assembled view of the filter mechanism 30, certain components of the plenum 34, the filter shaker mechanism 31, and other associated components which, in part, comprise the street sweeper 10, the present invention。 The plenum 34 is formed in part by the illustrated compo- nents, as well as other components including portions of sidewalks of the hopper 14。 The illustrated components of the plenum 34 include a multi-angled and configured rear plenum panel 60 having planar regions 60a, 60b, 60c and 60d, an angled and configured front plenum panel 62 having planar regions 62a and 62b, and an angled and configured right plenum panel 64 having planar regions 64a and 64b。 Inlet ports 66 and 68 are located along and about the planar region 60b of the rear plenum panel  60。 来;自]优Y尔E论L文W网www.youerw.com +QQ752018766-

[0032] The orificed plenum array 35 includes a plurality of valve orifices 70a-70n bordered by an angled front planar region 35a and an angled rear planar region 3$b, as well as a lower inlet port 72 at one corner of the orificed plenum array 35。 The angled front planar region 35a and the angled rear planar region 3$b of the orificed plenum array 35 align to and extend between the angled planar region 62b of the front plenum panel 62 and the angled planar region 60d of the rear plenum panel 60, respectively。 A plurality of inverted angle stock members 74a-74n align between the front planar region 3$a and the rear planar region 3$b of the orificed plenum array 35 to longitudinally separate the valve orifices 70a-70n and to offer support of the valve orifices 70a-70n。 Each of the sides of the angle stock members 74a-74n presents a 45° angled surface with respect to the valve orifices 70a-70n。 The 45° angle surfaces of the angle stock members 74a-74n serve to assist and channel dust and small debris through the valve orifices 70a-70n during the filter cleaning process, as later described in detail。 A plural- ity of flap valves 37a-37n align to and secure to the underside of the orificed plenum array 35。 The first flap valve 37a aligns to the first row of valve orifices 70a-70n containing valve orifices 70a-70c and each of the remaining flap valves 37b-37n aligns successively to the other rows of valve orifices 70a-70n。 Identically constructed stop rods 78a and 78b secure to the underside of the orificed plenum array 35 by like brackets  80。

无发明背景 1。发明的领域

该发明是一款经过改进更加实用的道路清洁车，它可以通过两个及以上的清洁头进行清扫而且还具有一个真空吸尘装置进行防尘控制。

2。先进技术介绍

在扫路机的防尘系统技术中多次使用到水。在清扫的过程中用水打湿路面上的残渣和污垢防止灰尘飞舞。在该系统中，水必须从各方向喷洒，比如，撒向主要的旋转扫帚和滚动扫帚。洒水系统经常只是打湿小车行驶经过的残渣和污垢，然而打湿后了的残渣和污垢仍然附着湿的路面上而不是被带进输送机或者垃圾箱。在清洁后不希望有湿的残渣和污垢时可以使用真空吸尘器来带走飞舞的灰尘来替代洒水系统。真空吸尘系统一般分别使用单独的专用风扇从主旋转扫帚和滚动扫帚的范围吸走灰尘。但是单独的专用风扇会造成过多的空间被占用导致制造过程的浪费。而且使用这种风扇还会产生一个问题，一个风扇产生的真空环境可能在进入正常的真空室或者增压室时会影响到另一个风扇。
