Self-picking sweeper

The invention relates to a self-contained sweeping machine with rotating roller brush and a collecting container for the picked garbage.

In the known aelbetaufnehmenden Kehrmaschlnon the refuse in general to mechanical We ^ e and / or is taken up with pneumatically operating means and supplied to a collecting container, the inlet is usually a considerable distance, etc. is higher than the sweeping surface.

The use of those devices that exclusively deal with Luehanian active debris collecting devices is primarily indicated for the collection of coarse waste parts, well finer sand or dust particles from the bristles of a rotating one The main brush can be picked up "but then fall back onto the sweeping surface because the bristles of a main brush acts like a sieve, which lets the finer particles fall back through its meshes the operator of such a sweeper is inevitable, because the dust particles that are blown up are unhindered to the side of the main brush and from other openings in the machine can emerge.

The disadvantageous dust nuisance is largely avoided by using an air stream directed from the sweeping surface to the collecting container In this case, however, it is inevitable that specifically heavy boiling sticks will fall on the rotary brush. fall back on the swept surface. The sweeping results are unsatisfactory, especially with gmuehtttm and durshnäStem debris. Naetiteilig 1st further that consumpt @ ias> eSie Schmutstelle dan "mur Kehrfläcb" can also surUekfallen,

e) a fan, which directs an air flow to the collecting container generated.

In a particularly preferred embodiment of the invention is the brush roller that comes into contact with the ground opposite in the direction of travel vorveraetzt the roller or rollers rotating above it.

Whatever the case, it is advantageous to change the angular positions and / or angular velocities of the orphans individually or collectively Xehraltteln (bristles) of the floor-contacting orphan passes the inlet of the shaft, if a free roughness swiaohen the segment of the sweeping agent of the higher-level conveyor wheel stands in the same place.The combination and the arrangement of the floor-covering and higher-ranking orphan in the indicated way ensures a return-free Promotion of refuse. Ss ll ^ further t la Rahwen of the invention, the wound of the schachtartlgen Oehäuses largely adjust the sylindrieohen Fora of orphans and swiscben dea housing part for a roll and the overlying Raua _f in welohea sB · ualäuft a Fördervalse or Einlaufund disposed baffle for Kehrichtsaßimelbehälter 1st , f form a slit-shaped discharge opening * Here, the border edges of the slit-shaped discharge opening are bead-reinforced on the inside of the flange. In addition, it is advantageous to replace the lower orphan that touches the ground, when it is worn out, for the upper, even less used, valve. These measures are suitable for increasing the throat effect.

Further advantageous details of the status of the invention are identified in the sub-claims and are based on of the execution example shown in the drawing described below explained in more detail. This sssigt a sweeper la I in a schematic representation Seiteneohnitt, and swsr in

This avoids that the broom orphans 9 and Io already picked up rubbish when it is switched off the sweeping rotation fall back on the sweeping surface can"

The two orphaned brooms 9 and 10 are surrounded by a housing 12, 13, 1Ί, the walls of which are made up or partly made of flexible material or made of sheet metal. The walls of the housing 12, 13/14 enclose both Valsen 9 and Io tightly and give only one passage for the rubbish, which is directed essentially from bottom to top, especially the one in the direction of travel lying wall! Ie 13 and 1 * 1 of the housing are so tight used on the Besenwolzon, since the sweeping agents 15 and 16 of the orphans 9 and 1o at the Vorbelstrelehen on these wall parts 13 and 1 * »to be elastically written«

The housing is drawn in between the wall parts 13 and 13 adapted to the rounding of the surfaces of the orphans 9 and 1o It then forms a length of the rollers 9 and Io tongue-like cutting edge 17 through which the opening 18 ″ wipe the space in which the lower orphan 9 runs around and the upper space of the orphan Io is kept so narrow that it about the width of the free space between the Kehrmlttelaegmen- ** "15» 16 corresponds.

At those points of the wound parts 13 and 1 * »where the rotating sweeping means 15 and 16 lift off the wall and are relaxed, relucant edges 19 and 20 are arranged, and the edges cause the sweeping parts required by the sweeping means 15» 16 to be thrown away The rubbish is thrown through the opening 16 between the Kebrmltteleegmente 16 of the second rotating orphan Io The edge 2o causes a hurling of the further conveyed dirty parts through the tray outlet 21 of the housing into the Mttl! Collecting container 22, which is at the end of the Fahrseugea 1 on a console 23 is attached. The arrangement is closed to reduce dust by means of a flap 2k.
