Self-collecting sweeper

The invention relates to a self-picking sweeper with a coarse protective container and a dust container Blower suction in the area of the dustpan, with the separation of the dew by means of a pressurized filter arrangement he follows.

The rubbish ε is generally picked up in white

separate collection containers, namely a dirt kaeten for coarse or damp waste and a dust bag, in which light debris due to the fan air flow be promoted.

It is known that the filter element for receiving the fine pigeon to be arranged on the suction side of the fan. In this way iConstruction advantages are achieved, which are not detailed here to be discussed bit. 2 for the idea of a better sweeping

element to be attached to the pressure side of the blower (French patent publication 1 336 970, Pig. 5). Those who work according to this principle Sweepers have the disadvantage that as a result Heavy dust deposits in the filter, which may appear after a short visual time, are overpressure the filter builds up, through which the already absorbed build-up under the sealing lips between the coarse dirt or Dustbin and the roadway is blown out again. In addition, there is still the general problem of a * dust-free

dust container. Lei sweepers of the type mentioned was previously this ifntleerun ^ without bothering the operator, raised dust not feasible.

To avoid the disadvantages of sweeping machines of the type mentioned at the beginning, so that the air stagnation created by clogged pores in the filter element is not able to blow out the dust quantities that have already been picked up and deposited, thus calling into question the success of the sweeping process. Further, the operator when emptying αετ machine by whirled staubförsiges sehrgut should not be bothered

According to the invention, this is achieved in that the fan together with the dexa filter element and the dust collector one from the Grot dirt collecting container during the honorary operation forms a separate unit. Here, according to the invention, the clay deposit is used as a sealing shut-off element between the

J The separation of the fan with the fine dust filter and the

Dust deposit from the coarse dirt container during sweeping operation does not allow the already deposited amounts of dust, in the event of undesired changes in the pressure ratio on the filter element, to get back to the dustbin and interfere with the sweeping work, if the sweeping belt is finished or then when the ctaubsaramelablaee is filled, the fine dust can as a result of a movable shut-off element between the Grobechmutz and Peinetaub collection containers arranged one above the other be emptied from its upper shelf into the coarse dirt container underneath, without the Reservoir guide between the two BehHltÄlOi can be released got to.

The sweeping machine is formed by a sweeping box 1 connected to the chassis, in which the sweeping roller 2 is mounted iet, which is driven by the motor 3 placed on the dustpan. There is a fan on the motor housing 4 flanged, its rotor 5 also from the motor

is driven. The air flow generated by the fan sucks the dust whirled up by the roller brush 2 through the suction opening 6 and pushes it through the duct 6 ^f , into the dust filter bag 7, in which it settles near the ground, while the filtered suction air through the walls of the filter bag again escapes into the open. Heavy coarse debris * picked up by the roller brush is deposited in the debris box 8. The opening mouth 9 of the dust filter bag 7, which is coaxially located above an opening 10 of the coarse dirt collecting box 8, is stretched over a sleeve 11 (Fig. II and III), on the flange 12 of which extends at right angles to the axis a of the filter bag opening a bolt 13 pivotably held bottom closure plate 14 for the dust filter bag 7 is mounted. the
