Definitions
- the invention relates to a sweeper with a chassis, with unguided rear wheels and steered front wheels, with one arranged substantially above the rear wheels and this driving motor, with one the motor adjacent seat as well as with one on the underside of the chassis between the front and rear wheels across Arranged sweeper roller and a dirt collector.
- Such sweepers are used, for example, for cleaning used by streets and squares, the one to be cleaned Surface swept with the broom and the dirt in the Dirt collecting container is collected.
- DE-A-22 63 224 discloses a sweeper, at the dirt from two plate brushes in front of one in the direction of travel Sweeper roller arranged behind the plate brushes swept which then picks up the dirt and into the Dirt collecting container transported.
- the dirt collector is arranged and embraced between the two rear wheels a swivel device so that it is against the direction of travel pivoted upwards and then over a Flap facing the rear wheels can be emptied.
- the end the aforementioned publication has known sweeper thus a complex construction using a Large number of moving parts and is therefore susceptible to failure.
- the use of a total of three sweeping brushes can produce a considerable amount of dust on dry surfaces result, the dust occurring only for Part is transported into the dirt collector.
- the object of the present invention is a sweeper of the generic type in such a way that it is a has a compact, structurally simple structure and at a low Dust development shows a good sweeping effect.
- the sweeping roller and the dirt collector side by side between the front and rear wheels arranged this has a particularly compact Construction result.
- the sweeper additionally includes a suction unit that takes the dust into the dirt collector sucks in. So in the limited space between the The largest possible dirt collection container on the front and rear wheels can be arranged is in the invention Construction provided that the suction unit over a Suction line is connected to the dirt collecting container and thus be arranged at a distance from the dirt collection container can.
- a particularly compact design without the use of construction complex means is achieved in that the engine is arranged vertically, i.e. with essentially vertical aligned output shaft, both upwards and also protrudes downward from the engine.
- suction unit above the engine upwardly projecting section of the output shaft adjacent to arrange, because this is a particularly compact and space-saving construction results.
- the transmission can, for example, V-belt pulleys for the Include rear wheels and V-belts that drive the roller brush.
- V-belt pulleys for the Include rear wheels and V-belts that drive the roller brush.
- the V-belts also advantageously as Coupling elements can serve by changing their tension becomes.
- Sweeper is provided that the sweeper driving V-belts on a non-rotatable on an intermediate shaft held V-belt pulley attacks, the Intermediate shaft rotatably mounted coaxially to the axis of rotation of the sweeping roller is in operative connection with the sweeping roller via gear means stands.
- the coaxial arrangement of the intermediate shaft the drive movement can be made to the axis of rotation of the sweeping roller the output shaft can be easily transferred to the broom.
- a structurally particularly simple and inexpensive to manufacture Structure results from the fact that the gear means another between the intermediate shaft and the sweeping roller Grip V-belts with V-belt pulleys.
- V-belt driving the rear wheels on a V-belt pulley of an intermediate gear that attacks with the rear wheels is in operative connection.
- the intermediate gear can, for example, a V-belt pulley with variable outer diameter for speed regulation of the sweeper include. That’s it with simple means possible at the speed of the rear wheels constant speed of the output shaft of the motor vary.
- the Suction line switched on a fine dirt collection container the contains a filter from that through the fine dirt collector is passed through air flow. Thereby will a complete cleaning of the extracted air flow achieved, the cleaned dirt particles in Fine dirt collection containers are collected.
- the fine dirt collection container can be advantageous Embodiment arranged in the direction of travel behind the engine be. This results in particularly good accessibility of the fine dirt collecting container and the filter contained therein.
- the one Chassis 2 includes two non-steered rear wheels 3 and two steered front wheels 4.
- a motor 5 Above the rear wheels 3 a motor 5 is arranged, the output shaft of which is vertical is aligned, with an upper section 6 of the output shaft protrudes upwards from the motor 5, while a lower one Section 7 of the output shaft down from the engine 5 protrudes.
- a steering 8 is arranged above the front wheels 4, and between the motor 5 and the steering 8 is a Seat 9 positioned.
- a sweeper roller 10 Between the front wheels 4 and the rear wheels 3 are below the chassis 2 a sweeper roller 10 and this directly arranged adjacent to a dirt collecting container 11.
- the axis of rotation 12 of the sweeping roller 10 is transverse to the longitudinal direction of the sweeper 1 and thus also across it Direction of travel aligned.
- the dirt collecting container 11 stands over a suction line 13 with a suction turbine 14 held above the motor 5 Connection, being in the suction line at the rear of the sweeper 1 arranged behind the engine 5 in the direction of travel
- Fine dirt collection container 15 is turned on, which is a filter 16 contains.
- the filter can be used, for example, as a pleated filter be trained.
- the suction line 13 runs in parallel to the long side of the chassis 2 and enters the lower, the area of the fine dirt collecting container facing the rear wheels 3 15 in and out of its top facing the engine 5 out of this again.
- a plate brush 18 arranged around a in substantially perpendicular axis of rotation is rotatable.
- the suction turbine 14 is from the upper section 6 of the output shaft driven. For this there is a section 6 at the top V-belt pulley 19 held in rotation, so that the rotary movement the upper section 6 of the output shaft via the V-belt pulley 19 and one not shown in the drawing V-belt is transferable to the suction turbine 14.
- sweeping roller 10 is one in the on the chassis 2 Drawing schematically shown intermediate shaft 24 rotatable stored. This is not shown in the drawing V-belt pulleys held in rotation so that the intermediate shaft 24 over a substantially horizontal V-belt 25 is connected to the transmission 20 and via a substantially vertically aligned V-belt 26 with the sweeper roller 10 is connected.
- the plate brush 18 arranged in front of the front wheels 4 is driven by the lower section 7 of the output shaft.
