Street sweeper

The invention relates to a street sweeper with a water outlet opening on the waste bin cover. By Such an outlet opening is said to be used to bind dust in dry weather when sweeping the street Spray water or other rainwater that is sucked in from the road surface with the rubbish and that is in the Rubbish bin from the rubbish through rapid sedimentation and that separates the vibrations emanating from the extra work, can be drained in order to throw off unnecessary ballast and not to reduce the waste collection capacity, in particular before emptying the collecting container in a transshipment se O ^ Rainer.

Around the garbage grass when draining water: in the garbage bin to hold back, it is known to arrange sieve plates in front of the Wasserauslaßöffiiung. Put such sieves j close quickly and make the water outlet illusory.

j Even without a sieve, the outlet opening quickly clogs because

· 'Too much rubbish carried away into the narrowed outlet opening

will.

The object of the invention is to create a sieve device that is safe from clogging and yet highly effective is, so that almost all of the ι water accumulating in the waste collection room in a state that is as free as possible from waste parts.

; can be left.

<This demanding task is achieved according to the invention

j through a water outlet upstream of the water outlet

: Collection space with a louvre-shaped partition wall on the inside of the container solved, whose fixed blind slats in the water * i the collecting space is inclined upwards and narrowed at the bottom.

The water collection space according to the invention allows a by gradual seepage and thus slow flow "brought about collection of a water outlet portion that almost is free from contamination. The louvre slats form a screen fineness on their respective lower edge Narrowing and at their respective upper edge an overflow in the water collection space. This will put the water in a flow direction against the force of gravity upwards forced on the blind gaps, which is necessary for the separation of the Garbage is very beneficial. The narrow crevices are covered like a bulkhead. That is also extremely effective to prevent blockages »For this purpose, the blind slats can have an L-profile in the simplest form. These louvre blades also allow their gap passages by sucking in air by means of the sweeper fan through the open water outlet opening of leaves, Leaves and the like can be cleaned if the remaining water is drained before emptying the collecting container the gap openings should clog in the meantime.

In a further development of the invention, the water collecting space is formed by a box that is attached to the flip-up waste collecting container lid is hinged at a point remote from its folding axis, the box to the lid is open. When the lid is closed, the open side of the box is kept closed by the lid. at With the lid folded up, the box remains free to hang under its own weight on its pivot axis and can thus can be cleaned easily and conveniently by spraying water from a hose. There is also an attached one Box when emptying the garbage can by tilting it up with the lid folded up at the same time not in the way.

Furthermore, according to the invention, the box is open at the bottom and is closed by the bottom of the collecting container, when this is kept closed by its cover. For this purpose, the lower part of the box walls designed to be elastic, in particular in the form of a rubber apron

The water outlet opening in the lid is arranged above the sump. This becomes a in the box Sludge sump formed for the water collection room, which even passed through the narrow gap openings in the blind wall Contamination offers the opportunity to settle, so that they do not leak out of the Wasserauslaßöffnuiig. The sludge that has accumulated in this sump is emptied with its contents when the garbage bin is emptied at the same time emptied after the box swings out.

The box can easily be detached from the lid at its pivot point. This means that the new street sweeper stays with them their full collection container volume for collecting dry leaves in autumn.

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

Pig. 1 leaves the rear end of a street sweeper with the running wheels 1, the refuse bin 2 and the suction pipe 3 recognize. The open rear side of the waste collection container 2 is closed by a cover 4, which is used for Emptying of the collected rubbish can be folded up around a folding axis 5, like the Pig. 2 shows. In a certain The distance from the folding axis 5 is on a hinge axis 6 of the lid 4, a box 7 is articulated. It is open at the rear towards the cover 4 and at the bottom, so it only contains one right and left side wall 8, a ceiling 9 and for X A partition wall inside the waste collection container This partition wall 10 is formed by a series of fixed blind slats 11 of L-profile; they are to the interior of the box 7 inclined upwards and narrowed below, where the lower legs of the L-profile narrow gap openings set free. The lower part of the box walls is designed to be elastic in the form of a rubber apron 12 Cover 4, the skirt walls 12 are on the floor

of the collecting container 2, and closes uer lid 4 the Open back of the box 7 o The water outlet opening 13 in the cover 4 is within the water collection space 7 arranged above the collecting container bottom. As a result, the box forms a water collection space 7 with a mud sump

The rubbish a sediments in the collecting container 2, above which the water b which has been sucked in collects. The water passes through the narrow gap openings in the blind slats 11 and over their upper edges into the 7 / water collecting space 7 enclosed by the box. Any impurities still in it settle in the sump 14 ₀ The portion of water that has accumulated in the box can be drained through a street gully be, wherein a hose 15 with closure flap 16 can be helpful. The closure member 16 can be operated manually or remotely, for example pneumatically; 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 collecting container 2. After such water drainage, air can be sucked through the partition wall 10 by means of the sweeper blower with the closure element 16 open, whereby the narrow gap openings of the louvre blades 11 of leaves, leaves and the like. getting cleaned. This is best done with the drain. Remove the remaining water before emptying the garbage, it hurts if the crevices should clog in the meantime ₀

For emptying the collecting container it is according to Pig. 4 tipped up at the front and the cover 4 folded up about its folding axis 5. The seeded contents including the mud swamp is emptied because the box 7 with its apron 12 is there depends on it.

If the street sweeper is to be used for dry garbage collection in autumn, without taking in any water, the box at 6 can easily be unhooked and the hose 15 removed. _φ

The term "blind" includes an overlap of the individual slats in height, as the drawings show
