Definitions
- the invention relates to a sweeper with a chassis, with unguided rear wheels and steered front wheels, with a motor which is arranged essentially above the rear wheels and drives them, with a seat adjacent to the motor and with one on the underside of the chassis between the front - And rear wheels arranged transversely to the direction of travel and with a dirt collecting device.
- Sweepers of this type are used, for example, to clean streets and squares, the surface to be cleaned being swept with the sweeping roller and the dirt being conveyed into the dirt collecting device.
- a sweeper is known from German Offenlegungsschrift 22 63 224.
- the dirt is first grasped by two plate brushes and swept in front of a sweeping roller, which then picks up the dirt and conveys it to a dirt collecting container arranged between the two rear wheels.
- the uptake of the dirt from the surface to be cleaned into the dirt collecting container is thus quite complex and is usually associated with a considerable build-up of dust.
- the known dirt collecting container For emptying, the known dirt collecting container is pivoted upwards and emptied through an opening of the container arranged at the bottom. This can also lead to a large amount of dust.
- the object of the present invention is to design a sweeping vehicle of the generic type such that sweeping operation and maintenance are associated only with a low level of dust.
- the dirt collecting device comprises a coarse dirt collecting container arranged between the front and rear wheels next to the sweeping roller and a fine dirt collecting container which is connected to the coarse dirt collecting container via a suction line and from which a suction pipe leads to a suction unit.
- the coarse dirt is thus collected separately from the fine dirt and thus in particular from the dust that occurs.
- the coarse dirt container is arranged directly next to the sweeping roller, so that no additional parts are required to convey the coarse dirt into the corresponding coarse dirt collector. Dust and small dirt particles are sucked into the fine dirt collection container with the aid of the suction unit and cannot escape into the environment.
- the suction effect of the suction unit also causes a particularly effective absorption of the dirt from the surface to be cleaned and thus supports the cleaning effect of the sweeping roller.
- both the sweeping operation and the maintenance of the sweeper according to the invention are associated only with a low level of dust development.
- the coarse dirt collecting container as a drawer which can be moved parallel to the sweeping roller axis, since the coarse dirt collecting container can thereby be removed relatively easily and then emptied.
- the air flowing through the suction line experiences a weakening of its flow rate when it enters the fine dirt collecting container, since the effective flow cross section expands abruptly from the cross section of the suction line to the cross-sectional area of the fine dirt collecting container.
- the weakening of the flow velocity results in a separation effect for the dirt particles carried along.
- the fine dirt collecting container is connected to the coarse dirt collecting container via at least two suction lines.
- the filled coarse dirt collecting container can have a considerable weight, it is provided in a preferred embodiment that the coarse dirt collecting container is designed in the form of two opposing drawers, each arranged on a longitudinal side of the sweeper and displaceable parallel to the sweeper roller axis. each drawer being connected to the fine dirt collecting container via a suction line.
- the coarse dirt collecting container is thus divided into two separate drawers, each of which can be removed from one long side of the sweeper and can then be emptied. For this purpose, only half as much effort is required as when using a one-piece coarse dirt collecting container.
- the fine dirt collecting container can be arranged behind the engine of the sweeper in the direction of travel.
- a filter is arranged in the fine dirt collecting container, which filter covers the cross section of the suction pipe emerging from the fine dirt collecting container. This results in complete cleaning of the extracted air stream, the cleaned dirt particles being kept in the fine dirt collecting container.
- the filter is held within the fine dirt collecting container on a holding frame with a distance from the mouth area into the fine Dirt collecting container opening suction line, substantially transverse to the flow direction of the air flow entering the fine dirt collecting container arranged side wall.
- the side wall of the holding frame thus forms the baffle described above, on which the air flow flowing through the suction line and the fine dirt collecting container is deflected.
- the fine dirt collecting container comprises a container bottom which can be pivoted about a pivot axis arranged transversely to the direction of travel. The container bottom is pivoted for emptying, thereby creating access to the interior of the fine dirt collecting container.
- the container base can be pivoted downwards in the direction of the rear wheels arranged in front of the fine dirt collecting container in the direction of travel. This makes it possible to empty the fine dirt collecting container, in particular filled with dust, by pivoting the container bottom downward and then sucking the container out, for example with the aid of a vacuum cleaner.
- the container bottom is essentially convexly curved, since this increases the volume of the fine dirt collecting container and the collected dirt particles remain securely in the curved region of the container base when the container bottom is pivoted.
- the filter is arranged inside the fine dirt collecting container on the container ceiling opposite the container bottom.
- the filter In such an arrangement of the filter, retained dirt particles fall down due to their weight, so that in particular the dust collects on the bottom of the container during operation of the sweeper and can be easily removed from there.
- the filter can, for example, be designed as a pleated filter. This has the advantage that it has a particularly large surface area and great stability.
- a slide is arranged inside the fine dirt collecting container and can be moved along the inside of the pleated filter facing the container bottom. If the slide is moved along the inside of the filter, it thus brushes along the butterfly filter and has the effect that protective particles which have adhered to the filter are released and then sink to the bottom. This avoids clogging the filter and thus reducing the suction effect of the suction unit.
- FIG. 1 a schematic side view of a sweeper according to the invention
- Figure 2 is a schematic plan view of the sweeper according to the invention and Figure 3 is a schematic rear view of the sweeper according to the invention.
- a sweeper 10 which comprises a chassis 11 with two non-steered rear wheels 12 and two steered front wheels 13. Above the rear wheels, a motor 14 is arranged, above the front wheels 13 there is a steering 15. Between the steering 15 and the engine 14 has a seat 16 positioned on the chassis 11.
- a sweeping roller 17 and a coarse dirt container 18 are arranged next to it.
- the axis of rotation 19 of the sweeping roller 17 is oriented transversely to the longitudinal direction of the sweeper 10 and thus also transversely to the direction of travel.
- the sweeping roller 17, like the rear wheels 12, is driven by the motor 14 via drive means (not shown in the drawing).
- the coarse dirt collection container 18 comprises two opposing drawers 20 and 21, each accessible on a longitudinal side of the sweeper 10 and displaceable parallel to the axis of rotation 19 of the sweeper roller 17, which are arranged in a drawer arranged between the sweeper roller 17 and the rear wheels 12 and held on the chassis 11 22 are inserted.
- the drawer 22 On the long sides of the sweeper 10, the drawer 22 is covered by a pivotable cover 23 and 24, respectively.
- a fine dirt collecting container 25 is arranged at the rear of the sweeper vehicle 10, which is connected to the drawers 20 and 21 via lateral suction lines 26 and 27 and from which a suction pipe 28 to a suction unit in the form of a Blower 29 leads.
- the fan 29 is arranged above the motor 14 and is driven by it.
- the fine dirt collecting container 25 is essentially cuboid with a cover 30 facing the seat 16, with a convexly curved base 31 opposite the cover 30 and with side walls 32 projecting vertically from the cover 30.
- the base 31 is on the side facing the rear wheels 12
- the ceiling 30 is broken through in the middle by an opening 33, into which the suction pipe 28 opens, which creates a connection between the fine dirt collecting container 25 and the blower 29.
- the opening 33 is closed by a Pleated filter 34 covered, which is held on the ceiling 30 by means of a holding frame.
- the holding frame comprises two holding plates 43 and 44 which run parallel to the longitudinal sides of the sweeper vehicle and act as baffle walls serve for the air stream entering the fine dirt collecting container 25 via the suction lines 26 and 27. This is deflected laterally along the holding plates 43 and 44 to the rear, with which entrained dirt particles are separated.
- a slide 38 is slidably held on two holding rods 36 and 37. It is connected via a pull rod 39 to a handle 40 arranged on a long side of the sweeper 10 outside the fine dirt collecting container 25. If the pull rod 39 is pulled outwards by an operator using the handle 40, the slide 38 is thereby displaced along the inside 35 of the pleated filter 34. It brushes along the pleated filter 34 so that dirt particles adhering to it are loosened and sink down to the bottom 31 of the fine dirt collecting container 25.
- a plate brush 42 is arranged via a cantilever 41, which can be rotated about an essentially perpendicular axis of rotation and which is also driven by the motor 14 via drive means not shown in the drawing.
- dirt particles are first conveyed into the two drawers 20 and 21 of the coarse dirt collecting container 18 under the action of the sweeping roller 17 and the air flow generated by the blower 29. While larger debris Remain in it, smaller dirt particles are passed through the suction lines 26 and 27 into the fine dirt collecting container 25 due to the suction effect of the fan 29. The air flow is then cleaned with the aid of the pleated filter 34, so that the dirt parts remain in the fine dirt collecting container 25.
- the covers 23 and 24 are opened and then the drawers 20, 21 are pulled out of the drawer 22. If the fine dirt collecting container 25 is to be emptied, the base 31 is pivoted downwards in the direction of the rear wheels 12.
