Definitions
- the present invention relates to a suction sweeper, comprising a sweeping unit with a rotating drivable roller brush and a suction unit, which is a suction fan, a suction shaft and a suction mouth comprises, the suction mouth two substantially extending parallel to the roller brush Has boundary walls.
- Suction-sweeping units of the above type are primarily used for cleaning traffic areas. she are used especially in airport sweepers, with which runways, runways and landing strips are cleaned become.
- the vacuum sweeper is at the rear arranged on the corresponding airport sweeper. It has an exposure width (e.g. 2.3 m) that is approximately corresponds to the vehicle width, so one as possible to achieve high area coverage.
- the sweepings collection is done pneumatically by suction using the Suction unit, where the suction is supported by the mechanically working, in the working direction behind the suction shaft or the suction shafts arranged Sweeper roller with essentially identical working width.
- EP 0083840 B1 discloses a generic suction-sweeping unit with a roller brush and a suction unit.
- the suction mouth can be a contact part ("wiper” or “comb"), which on the rotating roller brush abuts and in particular as boundary wall of the suction mouth adjacent to the roller brush is executed.
- wipe wiper
- German patent specification 19524203 Generic suction sweeper unit on at least one Side of the suction mouth on which ejector nozzle one connected to a suction hood of a side broom Suction line is connected. At least those an ejector nozzle is on the side facing away from the suction mouth Side with a "flexible air baffle", which in their over the edge of the outlet of the associated ejector protruding length adjustable is.
- the present invention aims to be one with little Effort-producing suction sweeper unit at the beginning specified type to create that in special way to take up sweepings with strong different compositions.
- the mouth cross section the suction mouth can be between one first and second configurations vary, where the first configuration of the first end position of the or shape-changing boundary wall of the suction mouth corresponds and by a relatively large, after below, to the surface to be cleaned and to the rear, to Roller brush open cross-sectional area of the suction mouth is marked, whereas the second configuration the second end position of the shape-changing boundary wall corresponds and by a relatively low, essentially only down, open cross-sectional area to the surface to be cleaned of the suction mouth is marked.
- first configuration the suction sweeping unit according to the invention is suitable especially to absorb dry Debris
- the suction sweeper unit according to the invention in excellent way to absorb liquid material suitable.
- the position or shape-changing boundary wall of the Suction mouth is connected to an actuator by the actuation of the position and / or the shape can actively change the relevant boundary wall.
- an actuator for actively change the relevant boundary wall.
- mechanical, electromechanical, hydraulic and pneumatic actuators for example, mechanical, electromechanical, hydraulic and pneumatic actuators.
- the boundary wall of the suction mouth adjacent to the roller brush of the suction sweeping unit according to the invention in the form a flap by running parallel to one another axis pivotable to the roller brush is stored on the suction shaft.
- the position or shape changeable Boundary wall of the suction mouth in shape a swiveling flap is particularly preferred in its second end position in essentially vertically on the surface to be cleaned directed. This results in a particularly good one Suction power of the suction mouth with regard to the intake of liquids.
- roller brush can be raised is stored.
- the roller brush can in particular then when the vacuum sweeper is clean Liquid absorption is used, except for contact with the ground to be brought. This not only affects the mind a reduction in drive power; also lets wear on the roller brush to reduce.
- the liftable roller brush is particularly preferred by means of mounted on a swing arm. This especially allows favorable kinematic conditions between the roller brush, whose diameter changes due to wear, one side and that adjacent to the roller brush Boundary wall of the suction mouth on the other hand in the sense an optimization of the cleaning performance during the entire life of the roller brush.
- the pivot point the rocker is particularly preferably in the working direction in front of the suction shaft.
- the present invention can be used with particular advantage use in such vacuum sweeping units that include a sweeper, which is on wheels on the supports the surface to be cleaned. Because in this case holds the suction mouth regardless of possible pitching movements the vehicle always its optimal set Arrangement of the surface to be cleaned.
- suction sweeper unit can be duplicated can.
- two can on the suction mouth Suction shafts with two suction fans must be connected.
- roller brushes can also be provided, for example his.
- the position or shape-changing boundary wall of the Suction mouth next to their two end positions, if necessary Can take intermediate positions.
- suitable Known as such locking and clamping devices that for example, the actuator (see above) can.
- the Locking device used can be the Position or shape of the one adjacent to the roller brush Boundary wall in discrete steps or continuously change.
- the vacuum sweeper unit illustrated in the drawing comprises a sweeper 1, a suction unit 2 and one Sweeping unit 3.
- the sweeping unit 3 comprises a roller brush 4, which by means of a (not shown) Drive motor rotatable about its axis 5 (arrow A) is.
- the roller brush 4 can be raised in the Sweeper 1 stored. For this it is by means of Swing arm 6 is suspended pivotably about axis 7. This form of suspension allows the roller brush not just actively lifting them to keep them out of contact with the ground to bring (see Fig. 2). Rather, it is the same Suspension of the roller brush also its wear-related Change in diameter as shown in FIG. 1 using the worn ones shown with dashed lines Roller brush 4 'is illustrated.
- the suction unit 2 comprises a (not shown) Suction fan to which a suction shaft 8 is connected which is adjacent to the surface to be cleaned 9 in a suction mouth 10 passes.
- Suction shaft 8 and suction mouth 10 are arranged in the direction of travel B in front of the roller brush 4.
- the suction mouth is limited by a front from the roller brush 4 distant wall 11 and a rear boundary wall adjacent to the roller brush 4 12.
- the latter is designed as a flap 13, by extending around the parallel to the roller brush 4 Axis 14 is pivotally mounted.
- Fig. 1 shows the flap 13 in its first end position, in the they are essentially tangential to the roller brush 4 is applied.
- FIG. 2 shows the flap 13 in its second End position in which they are essentially vertical is directed to the surface 9 to be cleaned. hereby there is a mouth cross section 15 with a comparatively small cross-sectional area, the Mouth cross section at this position of the flap 13 essentially downwards, to the surface to be cleaned 9 is open by the lower edges of the two boundary walls 11 and 12 of the suction mouth 10 in this position the flap 13 at substantially the same distance Comply with the surface 9 to be cleaned.
- Fig. 1 shows that the flap 12 regardless of the degree of wear of the roller brush 4 or 4 'in their first end position essentially tangential to the Roller brush fits and in this way in particular can act more efficiently as a scraper.
