  • Sports fields and here preferably sports grounds with an artificial turf, have an introduced into the artificial turf covering filling material that influences the characteristics of the artificial turf or determines and adapts to the respective sports to be performed on the sports field.
  • Over time accumulate on the surface, and in particular on the artificial grass pitch, impurities and other particles, such as dusts, which combine with the contents and thereby adversely affect the characteristics of the sports field. It is therefore intended to remove the contents at regular intervals from the artificial turf pitch, rid of particles and adhering dirt and then bring back into the sports field.
  • the document DE 44 08 247 A1 shows a cleaning device for sports flooring with litter, preferably in the form of sand, which is designed such that hardened or encrusted surface layers can be broken so that the brush roller can penetrate. In addition, it should be possible that a wet surface layer is replaced by a dry layer.
  • the cleaning device furthermore has a sieve for screening out larger foreign particles than the grain sizes of the litter.
  • the document DE 88 04 130 shows a machine for cleaning artificial turf with a collection box designed as a sieve. Heavier particles of sand and granules fall back onto the sieve and through the sieve onto the artificial turf. Lighter impurities are taken along by the air flow and deposited in the filter.

  • the invention is based on a mobile device, as described above, and suggests that the filter element is designed to be self-cleaning. Due to the self-cleaning design of the filter element, the maintenance and cleaning intervals of the device are extended. In addition, filters must be replaced less frequently. Overall, these measures lead to a reduced service life of the device and increase its operational readiness and availability. With the linkage of the service life and the reduced maintenance costs due to less frequent filter changes, a significant increase in the efficiency of the device and a faster armortization of the acquisition costs are ensured. The reduced maintenance costs less operating costs, which in turn contributes to financial relief of the operator of the device.
  • the suction device sucks the particles directly from the surface, that is, for example, from a sports field or artificial turf, or is sucked into the device registered mixture of filling material and particles after entry into the device ,
  • the proportion of particles is removed from the mixture, which has a lower density, a lower weight and thus
  • Floating ability has. Only then can the extraction be ensured by means of air flow. At the same time the proportion of particles or particles can be selected via the strength of the air flow, which can / should be separated from the suction air flow by the filter or filter element provided in the suction device.
  • a sieve is arranged, onto which the filling material, the adhering particles and other contaminants, which are transported by the removal device into the interior of the mobile device, are thrown.
  • the sieve causes a separation of the contents of the other components of the mixture.
  • a preferred embodiment of the device comprises a sieve which is arranged inclined in or against the direction of travel or oriented horizontally. Moreover, it is considered favorable if the sieve is detachably or firmly arranged in the device.

  • the sieve can also be exchanged for a plate and the device can then be used to remove the contents.
  • the variably adjustable hole width is manually adjustable. This can be done for example via a lever arranged on the housing.
  • the hole width automatically is adjustable.

  • an exchange of the filter element must take place at corresponding time intervals.
  • the filter element is designed separable, so that after disassembly, only the filter medium can be removed from the filter element and replaced. This leads to a further reduction in maintenance costs and waste.
  • the filter element is designed so that it can be subjected to vibration.
  • vibration is imparted via a drive unit of the mobile device or a separate drive unit for vibrational loading in the Device is provided.
  • the vibration application may also be mediated via a main drive of the mobile device. This separate drive can be made smaller in relation to the main drive or be coupled via a transmission to the main drive.
  • the separate drive is powered by its own energy source.
  • an electric motor for the vibration loading of the filter element may be provided, while the main drive of the device comprises an internal combustion engine.
  • an eccentrically acting on the filter element, connected to the drive or the main drive lever is provided for Vibrationsbeaufschlagung. Due to the eccentric arrangement, the vibration of the filter element takes place without an uneven load of the main drive.
  • a preferred embodiment of the device according to the invention provides that a centrifugal separator is arranged upstream of the filter element.

  • a reversal of the flow direction can be achieved and the suction air flow can thus be introduced into the filter element in order to blow it out.

It is provided that the air flow is further guided via corresponding flaps, which are provided in the suction device. Through these flaps, a closure of the outlet opening for the suction air flow in the regular operation of the device can be performed.
  • the filter element which is in particular cylindrical or annular, is arranged on or on a first axis of rotation of the device. It is possible that the axis of rotation is arranged as a continuous axis in the device, or arranged as a two-part stub axle on two sides of the device or at two ends of the filter element.

  • the filter element extends only over part of the width of the device and is arranged, for example, in a separate housing provided in the housing of the device. It also proves to be advantageous if the filter element has a first, rotating section, which performs a prefiltration of the suction air flow and deposits coarse components from the suction air flow.
  • the correspondingly pretreated suction air flow then impinges in a fixed second region of the filter element, where it is freed from the substantially smaller particles which are still present in the pre-filtered air flow.
  • only the rotating area may be self-cleaning, while the fixed portion of the filter element is replaced regularly.
  • the rotating part is cleaned due to the centrifugal force acting on the deposited particles, while the fixed part is formed to be vibrated, for example.
  • a guide channel is provided for the suction air flow. Via a corresponding guide channel, which may be formed as a rail or pipe, the suction air flow will be selectively brought to the filter. It is then possible to use smaller filters. Also advantageous is the use of a guide channel in the already proposed cleaning of the filter by blowing, because here on the one hand, a directed impact of the air flow can be ensured on the filter element and on the other hand, the exiting particles are directed away from the filter.
  • a further embodiment of the device according to the invention provides that the filter element is arranged pivotably in the device. By pivoting the filter element this can be pivoted into the exhaust air flow or swung out of this. About this possibility of inclusion or swinging it is achieved that the filter element is applied only periodically with the suction air flow.
