Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the air block which is reciprocatable by a driving means, is provided with a number of longitudinally spaced nozzles and is formed as an air chamber, such that air can be ejected along the full length of the air chamber if the displacement stroke is at least equal to the distance between adjacent nozzles (see, e.g., AT 387 139B).
  • the invention aims at improving the device of the kind mentioned in the preamble.
  • the device according to the invention has the characterizing features of claim 1.
  • the periodically reciprocating movement is being avoided and replaced by the opening and closing of parts of the air exhaust means.
  • the full length of the air block can be covered on the one hand, while the air consumption is being kept limited without a reciprocating movement of the air block on the other hand.
  • the invention also comprises a method for treating synthetic playing surfaces having particulate material spread on it, according to claim 8.
  • Fig. 1 is a very schematic transverse section of the air chamber of a first embodiment of the device according to the invention.
  • Fig. 2 is a perspective view of the element which is rotatable around the air chamber of Fig. 1.
  • Fig. 3 is a very schematic section of the air chamber having nozzles according to a second embodiment of the device according to the invention.
  • Fig. 4 is a section along the line IV-IV in Fig. 3.
  • Fig. 5 is a schematic longitudinal section of a third example of an embodiment of the device according to the invention.
  • Fig.s 6 and 7 are sections along the line VI-VI, VII-VII respectively in fig. 5.
  • the present invention is intended for cleaning synthetic playing surfaces, such as for example tennis courts or hockey fields or the like, where a particulate material, such as sand or gravel is spread on a plastic fibre mat between the filaments. After some time this material sticks and sets causing the field to become hard and impervious to water and less good usable. In order to make the playing field better usable air is being ejected against the surface in small jets and with great force, causing the particular material to loosen, the material thereby being blowing upwards. If the particulate material is now being caught, it can be cleaned and a separation can for example be made between possibly re-usable coarse particles and finer dust and dirt particles, which particles are being collected and discharged. If thereupon clean, new or cleaned particulate material is spread on the playing surface, the playing surface is again good usable.
  • a particulate material such as sand or gravel is spread on a plastic fibre mat between the filaments. After some time this material sticks and sets causing the field to become hard and impervious to
  • the device is provided with a frame of a self riding vehicle or a towed vehicle, which frame is provided with a chassis.
  • This vehicle is provided with an air compressor or is connected to an air compressor through a long hose of for example 120 meters for supplying compressed air of for instance approximately 10 bar.
  • This compressed air is supplied to the inlet of an air block, which is shown in Fig. 1, and which is embodied as an air chamber 1 mounted substantially horizontally and more or less transverse to the direction of movement of the vehicle.
  • the air chamber 1 has a circular cross section and is in this case provided with a slit-like air exhaust 2 pointed downwards and preferably at an angle of approximately 15 degrees relative to the vertical.
  • the air chamber 1 can have a length of for example 100 cm and can be of a diameter of approximately 2 inch.
  • One or more air chambers can operate next to each other in order to improve the working width.
  • a rotatably drivable element which is provided with plurality of nozzles 4, acting as air passage means spaced along both the length and the circumference of the air chamber 1, or as the case may be extended along the rotating element 3, for example in one or more rows along a helical line across the wall of the rotatable element 3 (see Fig 2.).
  • Fig. 1 it is further shown that, as seen in the direction of movement of the vehicle (right in Fig. 1), an inclined catching surface 5 is placed behind the air chamber, which catching surface catches the particulate material being ejected therein, and which further discharges it, for example through a flexible conveyer belt or shutter conveyer bringing the material through the unit to a point of discharge. From there on a further transport can take place through a vacuum hose or a motorized car.
  • Fig.s 3 and 4 show a second example of an embodiment of the device according to the invention, whereby the housing 16 of the air block is provided with an air chamber 11, air exhausts 12, a rotatable element 13 and nozzles 14.
  • the rotatable element 13 is not journalled concentrically around the air chamber 11, but next to it in a bearing chamber of the housing 16.
  • the rotatable element 13 is constructed as a roller and is rotatable around an axis parallel to the air chamber 11.
  • the nozzles 14 are provided stationary in the housing 16 of the air block and are in line with the air exhausts 12 of the air chamber radially relative to the rotatable element 13.
  • This rotatable element 13 is provided with air passage channels 17, whereby adjacent air passage channels are turned through an angle around the axis of rotation, such that along the circumference of the rotatable element 13 the channels 17 show a helical line path. In two 180 degrees shifted rotational positions every channel comes in line with the air exhausts 12 of the air chamber 11 and the nozzles 14, causing air in those positions to be ejected through the nozzles. Because adjacent air passage channels 17 are angularly offset, air is ejected sequentially and it is also possible here to cover the whole surface to be cleaned without excessive air consumption. In each winding of the helical line of the channels 17 two nozzles 14 can be active simultaneously. A number of the housings 16 as shown can be coupled to each other, whereby the rotation of the rotatable elements 13 can be transferred through coupling means 18, 19.
  • the Figs. 5-7 show a third variant of the invention, whereby the air block for alternatingly opening and closing of a row of nozzles 24 is provided with or is formed as a valve block 30.
  • Recognizable are now an air chamber or air supply channel 21, nozzles 24 and a catch surface 25.
  • the valve block which is positioned at an angle of 15 degrees has a number, in this case 12, of valves 31, shifting valves or other kinds of shutters which are included in channels 24' of the nozzles 24.
  • each two channels 24' are connected to a valve 31 in order to reduce the number of valves 31.
  • a nozzle 24 In a row of 6 adjacent nozzles each time a nozzle 24 is being opened sequentially, while the other five are closed. The position of the ejection of air then moves itself through this row.
  • all kinds of arrangements of valves, channels and nozzles are possible.
  • the invention provides a device and method, with the aid whereof air can be ejected every time on different closely spaced positions transverse to the direction of movement, thereby obtaining a good and reliable cleaning effect.
  • the operating means for this selectively ejecting air or a similar medium thereby act as valves of shutters which, like in the first two embodiments, can be constructed both as rotatable elements for a large number of ejection openings, and be constructed as real valves, shutters or the like.
