Definitions
- the invention relates to a sweeper, comprising a chassis for moving on a floor surface, sweeping on the overhead sweeping sweeping roller for cleaning the bottom surface, a Kehrschwelle having Groblegutabdeckung, wherein the sweeping threshold of the sweeping roller is upstream in a main movement direction of the sweeper and the sweeping roller in a covering position the Groblegutabdeckung partially covers, and an operating unit for transferring the Groblegutabdeckung of the covering in a release position.
- Such a sweeper is for example a Aufsitzledgemaschine or a hand-held trailing sweeper, which may optionally be provided with a drive for the chassis.
- Sweeping material is detected with the sweeping roller and transported into a dirt collecting container of the sweeper.
- the sweeping roller Relative to a main direction of movement, which corresponds to a longitudinal direction of the sweeper, the sweeping roller works on the overhead sweeping principle.
- the sweeping roller is rotatable about a rotational axis aligned transversely to the main movement direction. Bristles of the sweeping roller move close to the ground against the main direction of movement. The debris is thereby captured by the sweeping roller and transported over head, ie across the sweeping roller, in the dirt collecting.
- the sweeping roller is arranged upstream of the sweeping threshold in the main direction of movement.
- the sweeping threshold In a covering position of the large goods cover the broom is partially covered near the ground by the sweeping threshold.
- the Kehrschwelle moves over debris on the floor area away, so this can be detected by the sweeping roller.
- large sweepings are so big that the sweeping threshold can not move beyond them.
- the sweeping threshold is covered by the Grobspanngutabdeckung, which can be converted by operating the actuator from the covering in normal sweeping in the release position. Especially the bulk goods cover is raised. In the release position Groblicgut can get to the sweeping roller and detected by this and swept.
- the Grobspanngutabdeckung occupies the release position only for a relatively short period of time, so that debris is not moved out of a sweeping space in which the sweeping roller is arranged.
- the sweeping space is partially limited in the covering position of the bulk sweep of the Kehrschwelle.
- the Grossbeutegutabdeckung is commonly referred to as "Groblopegutklappe", especially as a “rough dirt flap”.
- the sweeping threshold can also be referred to as a "sweeping lip” because it can be deformable so that it can be moved over the sweeping material during the movement of the sweeper.
- debris is understood as meaning any material that can be swept up with the sweeper. This is particularly, but not necessarily, dirt or garbage. In a corresponding manner, high-yielding goods are in particular, but not necessarily, coarse or coarse waste.
- Object of the present invention is to provide a generic sweeper that is more user friendly.
- the sweeping machine according to the invention it is possible to determine, on the basis of the sensor unit and the control unit, whether or not bulk sweep of the sweeping threshold upstream of the sweeping direction is located on the floor surface. The presence of bulk food is detected by the sensor unit, which provides the control unit with a corresponding control signal.
- the control unit can transmit an actuation signal to the actuation unit, as a result of which the bulking product cover can be transferred from the cover position into the release position.
- the sweeping threshold no longer covers the sweeping roller near the ground or to a lesser extent than in the covering position. Big goods can be run over by the sweeper. This allows picking up debris automatically without user intervention with the sweeping roller. The user does not need to pay attention to whether or not there is large-size food on the floor surface. He can focus his attention on other operations during the cleaning operation. The handling of the sweeper is facilitated. In addition, bulky goods can be reliably absorbed.
- the Grossbeutegutabdeckung automatically returns, in particular under the influence of gravity, from the release position in the covering position.
- the Grobetzgutabdeckung is pivotally mounted or slidably mounted on a support means of the sweeper.
- the carrying device is, for example, a chassis or frame of the sweeper on which the chassis and / or the sweeping roller are held.

- One end of the tensile force transmission element may be fixed to the Rough earth cover, for example on one of the above-mentioned retaining arms. For example, the other end is wound on a winch rotated by the drive.
- the sensor unit is arranged at a distance from the sweeping threshold of this upstream of the sweeper in the main direction of movement. Due to the distance of the sensor unit to the sweeping threshold can be ensured in a simple manner that after the detection of bulk sweep sufficient time remains so that the Groblowgutabdeckung can be transferred from the covering to the release position. In practice, a distance of about 10 cm to 20 cm of the sensor unit proves to be advantageous from the sweeping threshold.
- the distance of the sensor unit from the sweeping threshold is changeable.
- the distance is variable depending on a speed of the sweeper, wherein the sensor unit may have a drive which is controllable and / or controllable by the control unit depending on a speed and / or speed change of the sweeper.
