Description

The invention relates to a street sweeper with a refuse collection container and a water outlet opening pm refuse collection container cover provided with a sieve device.

Such an outlet opening is intended to bind dust in dry weather when sweeping Spray water sprinkled on the street or rainwater sucked in from the surface with the rubbish and that is separated from the waste in the waste collection container by rapid sedimentation and that of the vibrations emanating from the sweeping work can be drained in order to throw off unnecessary ballast and not to reduce the refuse collection capacity, especially before emptying the collecting container into a transshipment conlainer.

In order to hold back the waste in the waste container when the water is drained, it is known to arrange Siebblet.he in front of the water system opening.

can.

According to the invention, this object is achieved by a device arranged upstream of the water outlet opening Water collection space, which is separated from the inside of the container by a louvre-shaped partition, whose Fixed louvre slats protrude inclined upwards into the water collection space and their mutual Gaps are narrowed at the bottom.

The water collection space according to the invention allows a gradual or slow seepage Flow causes collection of an outlet water portion that is nearly free of contaminants. the Venetian blind slats form a narrowing which determines the mesh fineness and on their respective lower edge their respective upper edge an overflow into the water collection space. This will keep the water in the Blind columns a direction of flow against the force of gravity forced upwards, which for the Separation from garbage is very beneficial. The narrow crevices are covered like a bulkhead. This, too, is extremely effective in preventing constipation. The blind slats in the simplest form have an L-profile. These blind slats also allow their gap openings through Sucking air by means of the sweeper blower through the open water outlet opening of leaves, Leaves and the like can be cleaned if, when draining the residual water before emptying the The refuse bin in the meantime should clog the gap openings.

The water collection room is in the process of being developed Invention formed by a box that attaches to the flip-up waste bin lid is hinged to a point remote from its folding axis and is open towards the lid. at When the lid is closed, the open side of the box is kept closed by the lid. When folded up The lid of the box remains hanging freely under its own weight on its pivot axis and can therefore easily and conveniently by sprinkling with water from one Hose to be cleaned. In addition, there is a box attached in this way when emptying the refuse bin by tilting it up with the lid folded up at the same time, it does not get in the way.

Furthermore, according to the invention, the box can be open at the bottom. He is here from the bottom of the Waste collecting container closed when it is kept closed by its lid. In addition isi expediently the lower part of the Kastenwändc elastic, in particular in the form of a Rubber apron.

The water outlet opening of the water collection space in the lid is preferably above the bottom of the garbage can arranged. This creates a mud sump in the box, which may still pass through the narrow Gap penetrations of the blind wall the possibility of impurities that have passed through Settling offers so that they do not leak out of the water outlet opening. The accumulated in this swamp Sludge is emptied when emptying the garbage can with its contents at the same time, the Box swings out.

The box can easily be detached from the lid at its pivot point. That leaves the road sweeper available with their full collection container volume for collecting dry leaves in autumn.

An embodiment of the invention is shown schematically in the drawing. It shows

Fig, 1 the rear end of a street sweeper in Longitudinal section,

F i g. 2 the rear end with the lid up,

F i g. 3 the associated rear view with partial section and ^r >

F i g. 4 the rear end with the refuse bin tilted.

F i g. 1 leaves the rear end of a street sweeper with wheels I, a refuse bin 2 and recognize an intake pipe 3. The open rear side κι of the refuse container 2 is covered by a cover 4 closed, which can be folded up about a folding axis 5 for emptying the collected rubbish, such as the Fig.2 shows At a certain distance from the The folding axis 5 is on a hinge axis 6 of the cover 4 r> a box 7 serving as a water collection space hinged. It is open towards the rear towards the cover 4 and towards the bottom, so it has only one right and one left Side wall 8, a ceiling 9 and a partition wall 10 towards the interior of the waste collecting container 2 This partition wall 10 is formed by a number of fixed blind slats 11 with an L-profile; they are for Interior of the box 7 inclined upwards and their spaces are narrowed below where the lower legs the L-profiles leave narrow gap openings. r> The lower part of the box walls is elastic designed in the form of a rubber apron 12. When the cover 4 is closed, the apron walls lie against the bottom of the garbage bin 2 and the lid 4 closes the open back of the in Box 7. A water outlet opening 13 in the cover 4 is within the water collection space 7 above the Collector bottom arranged. As a result, the box 7 forms a water collecting chamber with one another Mud swamp 14. r>

The garbage 7, above which the m'tangesaugic water b collects, sediments in the garbage collecting container 2. The water b passes through the narrow gap passages of the louvre blades II and over their upper edges into the water collection space enclosed by the box 7. Impurities still in it settle in the sump 14. The portion of water that has accumulated in the box 7 can be drained through a street gully, whereby a hose 15 with a closure flap 16 can be helpful. The shutter 16 can be manually or remotely controlled, e.g. B. pneumatically operated; it can also open automatically when a water column of a certain height weighs on it, whereby it is guided over the gutter and is automatically closed again by the negative pressure prevailing in the refuse container 2. After such water drainage, air can be sucked through the partition wall 10 by means of the sweeper blower with the flap open 16, whereby the narrow gap openings of the blind slats 11 are cleaned of leaves, leaves and the like! will. This is expediently ve when draining the residual water; emptying the rubbish if the crevices should clog in the meantime.

For emptying the garbage can this according to FIG. 4 tipped up at the front and the cover 4 by S '. A folding axle 5 folded up. The whole Contents together with the mud sump 14 is emptied because the box 7 with its apron 12 is there hangs swung out.

Should the street sweeper be used to collect dry leaves can be used in autumn without taking in any water, the box 7 Slightly unhook at 6 and remove hose 15.

The term "blind" includes an overlap of the individual slats in height, like the one Show drawings.
