Definitions
- This Invention relates to an apparatus for cleaning surfaces, such as roadways, runways, slipways, quaysides, railways, car parks, storage areas, driveways, sports surfaces, and in particular athletics tracks, and in particular to a cleaning apparatus for removing fine and coarse Infill materials from artificial playing surfaces such as artificial grass surfaces.
- the most common type of synthetic turf uses polyethylene or polypropylene fibres, typically around 10mm to 80mm long, which are tufted into a backing material.
- the material is infilled with a layer of silica sand and/or granulated rubber to support and stabilise the fibres, to enhance drainage and provide ballast to the material.
- the Infill layer becomes compacted and dirt and debris contaminate the inflll and form a crust on top of the infill layer, inhibiting drainage of surface water.
- Organic material such as leaves, may be broken down and mixed into the infill, leading to the growth of moss and algae on the surface of the infill layer. It is therefore desirable to periodically, typically annually, clean or replace at least an upper layer of the infill material to remove this crust of dirt, debris and organic matter.

- the air plenum may be adapted to be rotatably driven, in use, via a power take off of a vehicle to which the apparatus is attachable.
- Means may be provided for delivering a liquid to the air plenum to be entrained in the air stream exiting the air plenum via said at least one first air outlet.
- a tank may be provided on the apparatus for delivering said liquid to the air plenum.
- the liquid may be water or a liquid containing chemicals such as pesticides, insecticides, herbicides, colouring agents, cleaning agents, or de icing agents.
- the tank may be pressurised.
- the liquid may be delivered to the air plenum by one or more inlets provided in the air plenum and/or in the air supply pipe and/or the air supply manifold.
- the flow of liquid may be controlled by one or more valves.
- the liquid may be entrained Into the air supplied to the air plenum via a venturi nozzle.
- the apparatus may be provided with a vibration mechanism, such as an eccentrically mounted plate, bar, or roller to excite and dislodge material from the surface to be cleaned and/or from the surfaces of the cover.
- a vibration mechanism such as an eccentrically mounted plate, bar, or roller to excite and dislodge material from the surface to be cleaned and/or from the surfaces of the cover.
- a material collection device is connected to said exit port for collecting material dislodged from the surface to be cleaned.
- the collection device comprises one or more screw conveyors for conveying said material to a collection vessel or chamber.
- the collection device may comprise or include a separating device, such as a cyclone separator, for separating and collecting solids material dislodged from the surface to be cleaned from the air stream exiting the cover.
- the apparatus may be adapted to be mounted on a vehicle to be traversed across a surface to be cleaned.
- the apparatus is adapted to be mounted on a three point linkage of a tractor.
- the apparatus may comprise a wheeled frame arranged to be towed behind a vehicle, such as a tractor.
- the apparatus may be self propelled.
- One or more brushing devices may be mounted to the front, and/or sides and/or rear or of the cleaning apparatus,
- the one or more brushing devices may comprise bristles or metal tangs provided on one or more brushing heads.
- the one or more brushing devices may be raised and lowered to Increase or decrease the pressure on the surface to be cleaned.
- the one or more brushing devices may be fixed In position or may be mounted to oscillate horizontally or vertically or may be rotatably driven.
- a cleaning apparatus comprises an elongate hollow box section air plenum 2 mounted horizontally beneath a cover 4 for rotation about a central vertical axis.
- the air plenum 2 may have any other shape or cross section, for example S shaped or otherwise curved.
- a vertically extending air supply pipe extends centrally from the air plenum 2 for supplying compressed air to the air plenum, the air supply pipe 6 being mounted In the cover via bearings such that air plenum 2 and air supply pipe are rotatable about the axis of the air supply pipe 6.
- the upper end of the air supply pipe may 6 extend into an air supply manifold (not shown), via a sealed bearing to permit rotation of the air supply pipe with respect to the air supply manifold, the air supply manifold being connectable to a source of compressed air, such as a compressor.
- a pulley (not shown) may be mounted on the air supply pipe so that the air supply pipe and air plenum may be rotated by a motor, preferably a hydraulic motor (although an electric motor or other drive source may be used) via a drive belt.
- a belt tensioning device may be provided. The belt tension may be selected to enable the belt to slip In the air plenum becomes jammed to prevent damage to the motor and/or air plenum.
