Cleaning device for cleaning artificial floor areas provided with floor covering particles, especially for artificial turf
First Claim
1. A cleaning device for cleaning artificial floor coverings provided with floor covering particles, comprising:
- a sweeping device configured to gather dirt particles and floor covering particles from the floor covering;
a separation device configured to separate the dirt particles from the floor covering particles gathered by the sweeping device;
a filter device configured to filter dust particles;
a suction device configured to draw air from the area of the separation device through the filter device;
a first negative-pressure chamber and a second negative-pressure chamber, in which a negative pressure is formed by the suction of the suction device, the first negative-pressure chamber being formed above the separation device;
the first and the second negative-pressure chambers being in fluid communication through the separation device;
the second negative-pressure chamber being formed below the separation device, and a passage to the suction device defines an inlet which opens into the second negative-pressure chamber at a location below the separation device; and
the first negative-pressure chamber being in fluid communication with the suction device through the second negative-pressure chamber such that the suction device is configured to draw air from the first negative-pressure chamber through the separation device into the second negative-pressure chamber to collect the floor covering particles separated from the dirt particles in the separation device; and
a floor covering particle feedback device configured to feed back to the floor the floor covering particles collected in the separation device.

Abstract
A cleaning device for cleaning artificial floor coverings provided with floor covering particles, such as artificial turf, comprising a sweeping device for gathering dirt particles from the floor covering, a separation device for separating the dirt particles from floor covering particles, a floor covering particle feedback device for gathering the floor covering particles separated from the dirt particles and feeding back the floor covering particles to the floor, a filter device for filtering dust particles, and a suction device which draws air from the area of the separation device through the filter device. First and second negative-pressure chambers in which negative pressure can be formed by the suction device suction are formed above and below the separation device, respectively, in fluid communication through the separation device. The first negative-pressure chamber is in fluid communication with the suction device only via the second negative-pressure chamber.
