Street sweeper

The invention relates to a street sweeper whose Equipment in particular from rotating brooms, scrapers or scrapers, Aufnahraeeinrichtungen, refuse bins and water tank exists "

The known sweepers of this type are self-propelled Special vehicles specially built and as such for cleaning the streets in towns and villages is sufficient. ·

In the meantime, however, the road network has expanded considerably, in particular due to the expansion of the motorways outside the cities and through the construction of generous

Bypass roads on the hand of heavily populated areas is expressed »Through these new roads are also the demands on the street sweepers increased considerably, whereby various difficulties arose " These consist primarily in the fact that the capacity of the refuse container has become too small to allow a quick To enable processing of a longer road section in one operation. Rather, after a few Kilometers, work will be interrupted to return to EntAkte 2706Yes) * - 2 -

load to go to the next garbage dump The resulting time increases with increasing distance of the road section to be processed from the unloading point, whereby the costs for labor and fuel also rise sharply and sometimes even the use of a second sweeper is necessarya In addition, the use the street sweeper, which is very expensive to purchase as a pure transport vehicle with empty runs, is very uneconomical. Similar problems also arise with regard to the water supply, which is known to be necessary for street cleaning in dry weather and which had to be replenished with the previous machines after a relatively short working time _a

To nen the difficulties referred to begeg one has tried to turn over the rubbish on the track, d ₀ h ₀ to discharge the waste containers on the road and to bring through change vehicles on the shelf stockpile "However, this method requires the installation of special staging posts on the road and due to the driving of the sweeper from the street and the unloading also cumulative time losses, whereby the effort for the commute of the trucks caused additional costs'; .. In addition, the installation of the unloading places along the street means an undesirable increase in environmental pollution.

Another attempt to usefully solve these problems is that, especially on highways, a self-propelled rotary brush unit is used, whereby the waste is provided on a conveyor belt Truck is hauled o This is necessary for the Humidification of a tank truck is also essential This method is mainly due to the great expense of Si & individual vehicles and thus disadvantageous to personnel

The object of the invention is now to provide a road * - to create sweeper that is able to move over Pick up rubbish over long distances * and carry the required water with you, although only one to two workers are required and the number of empty journeys is significantly reduced compared to the previous ...

It would now be obvious to solve this problem by building a street sweeper with a considerably larger capacity for the rubbish and water container. This, however, would the cost shares in particular for the traction drive, so the engine, transmission, control, etc. _o so strong increase, that the economics of such expensive special vehicle ₀ which is only temporarily and the weather is ready for use, would be placed in embossing.

The invention therefore takes a different approach and proposes the complete equipment of the street sweeper. separating _t ie rotating brushes, scrapers »Aufnahmeeinrichtungan, garbage container and the water tank of the previous Fehr drive and these familiarization Ausrüstimg as a unit

ßeits to set on one or more driving axles and on the other hand with a self-propelled tractor, preferably a semi-trailer truck, separable and rotatable to couple ο

This makes it possible to increase the radius of action of the sweeper uo to increase the multiple compared to so far, so that the emptying of the refuse container was only after Route sections must take place, or "much less Unloading place © are required * The unloading points be arranged on the route to be processed at intervals that are adapted to the capacity of the sweeper sindp so that back trips or »trips with empty Containers are not required or only to a very limited extent * The same applies to refilling the water tank «

Another Vortfil of erfindungsgeaäßen proposal is that the tractor dee (Jespannet? Während'der rest of the sweeping machine for other purposes is used, whereby the Hehraufwand can be economically compensated for the large sweeper _o Add to this that the erflndungsgeraäße team when using self-steering Stools can also be used to clean streets, especially thoroughfares, in cities, the large radius of action also having an advantageous effect, since the frequent journeys to and from the unloading point so far often lead through the whole city and are therefore larger Cause expenditure of costs.

An exemplary embodiment of the invention is shown in the drawing »

Bs shows: Fig. 1 is a side view of the large sweeping

machine

Pig. 2 shows the plan of FIG. 1

The sweeping machine 1 is rotatably coupled to the tractor or the semi-trailer 2 at the front and is provided with a ZoB ₀ two-axle chassis 3 at the rear. The construction of the sweeper 1 essentially consists of a housing k _t in which the motor unit 5 for driving the exhauster 6 and the pressure unit for driving the rotating disc brush 7 and for the control parts is housed Driver's cab 9 of tractor 2 detachably connected »

In addition, the water tank 10 and the refuse container 11 are accommodated in the housing h;

In front of the circular broom 7 scrapers 13 are arranged which, like the brooms, can be swiveled up. As for the rest the functions of the sweepers are known, a more detailed description is dispensed with «
