Description

The invention relates to a street sweeper with a garbage bin and one with a Sieve device provided water outlet opening on the waste bin lid.

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 street surface with the rubbish and that is in the garbage bin from the garbage 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 storage capacity, especially before emptying the container in a transshipment container.

In order to hold back the rubbish in the rubbish bin when draining the water, it is known to use sieve plates to be arranged in front of the water outlet opening. Such sieves clog quickly and make di: n Water outlet illusory. Even without a sieve, the outlet opening clogs quickly because there is too much rubbish in it narrowed outlet opening is entrained.

The object of the invention is to create a street sweeper of the type mentioned at the beginning a sieve device, which afld safe from clogging is nevertheless highly effective, so that almost all of the im Any water that accumulates in garbage cans should be left out in a state that is as free as possible from KeIv straightening parts can.

This object is achieved according to the invention

through one of the water outlet opening upstream of the water collection space from the inside of the container a louvre-shaped partition is separated, the fixed louvre blades in the water collection space protrude inclined upwards and their mutual distances are narrowed at the bottom.

The water collection room according to the invention

ίο allows one by gradual seepage or slow Flow causes collection of an outlet water portion that is nearly free of contaminants 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, Scroll and the like. Can be agreed if when draining the residual water before emptying the The refuse bin in the meantime should clog the gap openings.

The water collection space is formed in a development of the invention by a box that is on hinged refuse bin lid at a point remote from its folding axis attached and open to the lid. When the lid is closed, the open side of the box is through kept the lid closed. When the lid is up, the box remains under its own weight its pivot axis can hang freely so that ukj can easily and can be easily cleaned by spraying water from a hose. Besides, there is such a thing Attached box when emptying the garbage bin by tilting it up at the same time not in the way of the flipped up lid.

Furthermore, the invention of the box can be measured be open at the bottom. It is closed by the bottom of the garbage can when this is kept closed by its lid. For this purpose, the lower part of the box walls is expedient

jo designed to be 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 swamp in the box, which may still go through The narrow gap openings in the blind wall allow impurities to pass 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 dessert content at the same time, with the Box swings out

The box can easily be detached from the lid at its pivot point. This leaves the road sweeper

sChine with its full collection container volume for Absorption of dry leaves in autumn Available,

An embodiment of the invention is in Drawing shown schematically, It shows

F i g. 1 leaves the rear end of a street sweeper with Laufrädei.i 1, a refuse bin 2 and recognize an intake pipe 3. The open rear side of the refuse container 2 is covered by a lid 4 closed, which can be folded up about a folding axis 5 for emptying the collected rubbish, such as the F i g. 2 shows. At a certain distance from the folding axis 5, there is a hinge axis 6 of the cover 4 a box 7 serving as a water collection space is articulated open at the bottom, so has only a right and a left side wall 8, a ceiling 9 and to the inside of the I garbage collecting container 2 towards a partition wall 10. This partition wall 10 is stronger by a row Louvre slats ti formed with an L-profile; si; are for The interior of the box 7 is inclined upwards and the spaces between them are narrowed at the bottom where the lower legs the L-profiles leave narrow gap openings. 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 down against the bottom of the garbage bin 2 and the lid 4 closes the open back of the 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 collection space with a Mud swamp 14.

In the refuse collection container 2, the refuse a sediments, over which the water b

collects. The water b passes through the narrow gap openings in the louvre blades 11 and over the 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 fan with the shutter 16 open, whereby the narrow gap passages of the blind slats 11 are cleaned of leaves, leaves and the like. This is usually done when draining the residual water before emptying the rubbish if the crevices should clog in the meantime.

To empty the garbage can this is shown in FIG. 4 tilted up at the front and the cover 4 folded up about its folding axis 5. The entire content including the sludge sump 14 is emptied, since the box 7 with its apron 12 hangs swiveled out

Should the street sweeper be used to collect dry leaves in autumn, with no If water is taken up with it, the box 7 can easily be unhooked at 6 and the hose 15 removed.

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