DESCRIPTION:
BRIEF SUMMARY
This invention relates to cleaning vehicles comprising matter removal means such as brush gear or suction gear, or both. An example of such a vehicle is a self-propelled cleaning vehicle for cleaning roads and/or runways and/or pavements and/or carrying out industrial cleaning and sweeping, the vehicle having suction gear including a suction nozzle with brush gear in the form of side brushes rotating about upwardly extending axes and serving to sweep matter laterally inwardly into the bath of the nozzle.
Presently available cleaning vehicles require improvement in respect of the brush gear and suction gear and associated assemblies, particularly their structure, mounting and control. As regards the suction gear, improvements are also needed in respect of the ducts and other assemblies, particularly their structure and arrangement having regard to air flow, power consumption and related factors.
An object of the invention is to provide cleaning vehicles, and other apparatus, providing improvements in one or more of these respects, or generally.
According to the invention there is provided a cleaning vehicle as defined in the accompanying claims. The invention also provides other apparatus as defined in the claims.
The invention also provides cleaning vehicles and other apparatus not limited by all features of any claim hereof and comprising any novel feature, or novel combination of features disclosed herein.
Embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which:
FIG. 1 shows a perspective view of a cleaning vehicle as seen from the front and to one side, with the brush gear and suction nozzle turned for a left hand corner;
FIG. 2 shows a perspective view of the vehicle of FIG. 1 as seen from the rear and one side, with the vacuum tank shown raised to its rear discharge position for emptying into a skip or the like, the steering gear and nozzle being shown turned for a right hand corner;
FIG. 3 shows a perspective view from the rear and one side of a suspension assembly forming a front steering unit for the vehicle and a support for the suction nozzle and brush gear;
FIG. 4 shows, on a larger scale, a vertical section in the front/rear direction through the suction nozzle and associated structures;
FIG. 5 shows a plan view of the left hand half of the nozzle of FIG. 4 as viewed in the direction of arrow V in FIG. 4;
FIGS. 6 and 7 show sections through the nozzle of FIG. 5 as indicated by arrows VI - VI and VII--VII in FIG. 5;
