Description

"Mobile device with a removal device ¹¹

The invention relates to a mobile device with a removal device for the removal of at least a portion of the possibly mixed with particles filling material from an artificial turf field, wherein the device has a separation unit, and the separation unit separates the particles from the contents.

Generic devices have a rotating brush that auskehrt from the artificial turf pitch or plastic turf the filling material, for example, sand and / or rubber granules, while also resting on the place dirt like Leaves, paper and so on.

With the help of the separation unit provided in the device, these particles are separated from the contents and afterwards the contents are again applied to the artificial turf pitch in a suitable manner.

In the prior art, it is known to provide a sieve as a separation unit, wherein the contents fall through the sieve and the dirt particles are separated. The resulting dirt and other particles are then collected in a collection container.

In the prior art, it is known to realize the screen as a drawer and therefore to provide a plurality of drawers, which differ in each case by a different ausiebbare grain size. This is on the one hand consuming and on the other inflexible.

It is an object of the present invention to propose a device as described above, which should be more versatile.

To achieve this object, the invention is based on a mobile device as described above and proposes that a variable, in particular continuously variable separation dimension for the separation of the particles is provided by the contents. With the mobile device traveling along a corresponding arrangement is provided, by which the separation measure, which is used in the separation unit and used to separate the particles of the contents (ie dirt from the interspersed sand or rubber granules), is changeable at any time. This ensures that during the use of the mobile device according to the invention, the separation measure is variable, for example, to the special conditions of the war- to in the short term to correspond to the artificial turf pitch to be cleaned and cleaned. In addition, the degree of separation is also variable based on the nature of the particle. This means that an adaptation of the separation size and thus the separation efficiency of the separator takes place depending on whether it is the particles are dirt that is separated from the contents, which is to be applied after the separation process again on an artificial turf field, or whether the separation of the particles of the filling material, as is the case for example in the preparation of an artificial turf pitch, is provided. In particular, in the cases in which an air classification of the particle mixture accommodated by the device is provided, the separation dimension is variable based on the particle mass. In this case, the admission of the particle mixture with an air flow is controlled via the variable separation measure, which causes only the particles are sorted out in a defined mass range. Of course, the term "particle texture" does not exclusively cover the abovementioned physical parameters of the particles. Rather, depending on the underlying configuration of the device, it is of course also possible for the particles to be selected on the basis of the chemical nature, so that the separation dimension is changed on the basis of this particle property in a correspondingly designed separation unit. Thus, a very flexible device according to the invention is provided.

Furthermore, considerable savings are saved by the proposal according to the invention. In the prior art, it is known to provide for the individual solid, discrete separation dimensions separate separation units in the form of corresponding sieves with corresponding sieve sizes. This leads to a corresponding expense for the provision of the sieves and, as stated, to a corresponding inflexibility in use. Because ultimately all available separation dimensions on the mobile device mitfahrend trained, this additional cost of equipment can be saved and in particular setup times can be saved, since the setting of the appropriate separation measure in use is immediate.

Due to the particular stepless variability of the separation measure, it is also possible to use the mobile device according to the invention not only for cleaning tasks, but also, for example, for maintenance purposes. Often, the contents of two different types of particles, for example, sand and granules, each with different grain size. Since the grain sizes may differ only by a few 1/10 mm under certain circumstances, with the help of the proposal according to the invention, a separation of the contents in the different two types of particles can be made, that is, the invention is not limited to the cleaning task of a corresponding artificial turf pitch. In addition to a considerable increase in the flexibility of the invention and higher availability of the machine, since the set-up times for changing the sieves omitted, it is possible with the device according to the invention, in addition to the known cleaning tasks of the artificial turf field, the device according to the invention additionally to use for maintenance tasks, if For example, the contents to change or edit accordingly.

In one embodiment of the invention, it is provided that a separation unit for the separation and partial recycling of the particles or the filling material is provided on the artificial turf pitch, wherein the return takes place directly from the separation unit. An advantage of this design is that after receiving the contents of the artificial turf or any other sports field direct return of a part of the contents can be done on the artificial turf field within a single operation. The filling material or a product defined by the separation unit or the setting of the separation unit. nierte fraction of the recorded contents is thereby returned directly from the separation unit. This feedback is carried out directly, that is, in the separation unit, a size selection of the contents is performed and the entire proportion of the contents with a previously defined or predetermined by the Trennmaß size immediately returned to the artificial turf pitch. An additional reduction of the recirculated amount, which would necessitate the presence of a further, interference-prone separation measure or an additional, appropriately designed separator, does not occur. Due to the lack of a further separation unit, it does not come to the accumulation of particles, which can lead to a blockage of the second, possibly incorrectly set separation unit.

The device according to the invention can also be designed so that the separation unit has a variable, in particular continuously variable range, and the particles are separated from the contents in this variable region of the separation unit. Furthermore, it is provided that the separation unit is also due to the design with multiple areas, of which a single area is changeable, even after changing the separation dimension is able to continuously, in particular interruption-free particles to be separated from the contents. A further embodiment of the invention provides that the mobile device according to the invention not only has a variable range, but a plurality of variable regions, which are arranged one behind the other. The arrangement one behind the other means in the present case that the areas can be arranged both processually and spatially one behind the other. According to the invention, however, it is provided that the area as well as the areas with respect to the separation dimension is or are changeable. According to the invention, it is provided that the individual constituents of the filling material as a particle of the remaining contents can be separated by the invention.

In a preferred embodiment of the invention it is provided that the separation unit has a plurality of openings for the passage of the contents and so the separation unit separates the particles from the contents and the opening width is variable, in particular continuously variable. According to this proposal of the invention is used as a separation measure the opening width of the openings of the separation unit, as used for example in a sieve, used. However, the invention is not limited to this, and other variants of a separation unit can likewise be used according to the invention in the same way. Here, for example, to think of an air classification, in which with a corresponding suction, the strength of which again represents the separation measure, the separation properties of a separation unit so equipped are set.

However, if the separation unit has openings, these are conveniently arranged in one plane. Due to this arrangement, particle blockages in the separation unit are avoided since only a single separation process takes place.

It is of great advantage that an adjustment device for the separation dimension is provided on the mobile device. This makes it possible to adapt the mobile device to the respective conditions on the artificial turf pitch directly and at short notice, since the adjusting device is always available on the device because it moves along with it.

In a variant according to the invention, provision is made for a brush rotating about an axis to be provided as the removal device. As an alternative to a brush, for example, a corresponding extraction system can also be used as the removal device. the suction on the artificial turf pitch particles and contents, similar to a vacuum cleaner sucks. However, the use of a rotating brush is possibly more effective, since a larger proportion of contents from the artificial turf can be worked out. The brush has, for example bristles, which intervene due to the rotating movement between the blades of the artificial turf and thus sweep the contents including particles. The axis of rotation is preferably parallel to the plane of the artificial turf, usually oriented horizontally.

In addition to the realization of a brush with bristles but also a variant is provided according to the invention, according to which on the brush according to individual massive tines are arranged, which optionally cooperate in combination with a bristle brush. The tines may optionally have a slightly greater length and thus engage more deeply in the interspersed in the artificial turf product and this loosen up accordingly. It is then possibly a lesser part with also turned out, but there is also a loosening of the interspersed filling in artificial turf.

According to the invention is thus carried out with a machining operation, that is, with one shutdown of the entire lawn, several operations, namely a removal of dirt particles and other particles, ie a cleaning of the place, possibly also a cleaning of the swept filling, connected with a loosening of not sweetened and at the same time a raising of the stalks of the artificial turf.

It has been found that under some circumstances a better working result results if the movement component of the brush in the area of the synthetic turf is in the direction of travel. If necessary, however, there is also another variant, namely that the movement component of the brush in the region of Synthetic turf is opposite to the direction of travel.

Cleverly, a height adjustment of the removal device is provided according to the invention, whereby the effectiveness range of the removal device can be adjusted. The height adjustment usually acts at right angles to the artificial turf pitch and ultimately determines the penetration depth of the removal device, for example, in the embodiment of the removal device as a rotating brush (possibly also with tines), up to which level the bristles of the brush particles and contents from the lawn.

In a preferred embodiment of the invention it is provided that the separation unit is designed as a double screen, with a first and a second arranged parallel thereto, the first relatively movable second sieve, wherein the sieves each having a plurality of sieve openings and the sieve openings arranged one above the other openings of the Form separation unit. Advantageously, the two screens used in the twin-wire are designed identically and to a certain extent relative to each other relatively movable, for example by the adjustment.

There are two variants for the design of the two screens. In a first variant, the first sieve is fixedly arranged on the device according to the invention and the second sieve is movable for this purpose. In the second variant, both screens are, for example, in opposite directions to each other movable. Cleverly, both screens are oriented parallel to each other, this does not preclude an arrangement in which these two screens also include a small angle to each other. This too is still covered by the term "parallel". Cleverly, an arrangement that is as parallel as possible is selected in order to avoid jamming of the contents to be screened due to the inclination between the two screens. An advantage of this embodiment with the screens according to the invention lies in the fact that it is very easy to solve and extremely effective. Alternatively, it is provided according to the invention to realize the separation unit, for example, by an air-sighting arrangement.

Cleverly, similar sieve openings are used in the two sieves. This means that the two screens have identically formed screen openings and also the webs, which are provided between the screen openings, are similar in each case. Thus, it turns out that in a position of the two wires of the twin wire to each other actually only one sieve is effective, since the second sieve is completely covered by the first sieve. This position then also corresponds to the arrangement with the largest separation size or Siebmaß, since here are the openings with the largest dimensions available.

In a preferred variant of the invention it is provided that the screen openings are rectangular or square and the sliding movement between the two screens is diagonal thereto. Preferably, a square configuration of the sieve opening, which is located in many ways on the respective sieves, sought, since in a simple manner, as proposed, the edge length of the sieve opening can be reduced or changed in both directions similar. If the sliding movement, as described, in the diagonal direction of a square, so emerges in a proportionate same way the second sieve under the first sieve and the webs of the second sieve similarly reduce the sieve opening of the first sieve to a resulting opening of the separation unit. Such an arrangement therefore ensures a similar adjustability of the separation unit with high quality of the separation result.

According to the invention, instead of being square formed sieve openings also use rectangular screen openings. It should be noted that the invention is basically usable even with polygonal screen openings. Also round screen openings and so on are used, with such forms of screen opening a reduction in the size of the separation may not result in a uniform reduction as in a square configuration of the screen opening.

In a simple embodiment of the invention, which is very effective and easy to use, it is provided that a slider or a thumbwheel is provided as an adjustment, the operation of which acts on the relative position of the two screens. If necessary, the setting device has a corresponding determination of the slide or setting wheel, so that the once selected separating measure does not change again automatically. The arrangement is to be realized without any problem so that a stepless, even as sensitive and well reproducible adjustment of the size of the separation by the inventively proposed adjustment is possible. Suitably, the adjustment device is also equipped with a corresponding display in order to display the currently used degree of separation to the user. This can be done in a simple manner by appropriately mechanically moving hands and the like.

Both the removal device, as well as the separation unit extend skillfully over the entire width of the mobile device in order to achieve the highest possible degree of coverage and thus to provide the largest possible processing width available. The result of this is that, under certain circumstances, a relatively high flow of expanded product has reached the separating unit, which has to be guided over the separating unit extending in the direction of travel. It is therefore provided in a variant according to the invention that the Separating unit has a transport arrangement for the contents to provide within the device according to the invention for a corresponding onward transport of the contents. In this case, it is desirable that the transport arrangement is realized in such a way that the filling material removed at the removal device arranged in front in the direction of travel is treated accordingly on the separation unit following in the direction of travel and is immediately re-installed into the space after the separation unit, if possible at the location it was expanded. It is therefore cleverly provided, if appropriate, a regulation or control for the speed of the filling material by the transport arrangement in the separation unit.

For the design of the transport arrangement, several variants according to the invention are conceivable. First, the principle of a shaking or vibrating trough off, as will be described further. But even the use of an air flow can serve as a means of transport for the contents in the separation unit, as can be realized, for example, in an air classification.

In a further embodiment of the invention, it is preferably provided that the twin wire is inclined at an acute angle, such that the collecting area located in front in the direction of travel is higher than the end area of the twin wire. This results in such a way and in a simple manner a transport arrangement for the contents, since this runs on the forming oblique plane.

Preferably, an angle of inclination relative to the horizontal of approximately 1 ° to 15 °, in particular approximately 3 ° to 9 ° is provided. In the embodiment shown in the drawings, for example, an inclination angle of about 5 ° is selected. Furthermore, the inclined arrangement of the twin wire but also helps that on the screen approaching product as evenly as possible to distribute the width, but also in the direction of travel. Here- By is achieved in particular that the most uniform installation of the previously removed and then cleaned filling material is achieved.

In a special embodiment of the invention is provided in particular (optionally together with an acute-angled inclined twin wire) that the transport arrangement is realized by a trained as a vibrating screen twin-wire. By shaking or vibrating the twin wire transporting is already achieved when this vertical movement is done namely with an inclined double screen. The configured as bulk material (sand, rubber granules or other pourable goods) then dance downright on the twin wire and are transported due to the inclined position of the higher to the lower area. Partly, of course, the contents gradually falls through the openings of the screen, but the particles to be filtered out are transported by the shaking movement in the lower end of the separation unit.

In a preferred embodiment of the invention, an eccentric drive is provided for the shaker screen. Due to the eccentric drive not only a high spin (only a vertical movement) of the contents is achieved, but the eccentric movement also includes a horizontal component of movement. This results in a high and back-to-move of the product-particle mixture to be separated.

The arrangement is chosen so that in the end of the screen, so at the lowest point of the screen, actually only a vertical movement is observed. Here is another transport movement usually no longer necessary, since then other mechanisms take effect.

According to the invention it is provided that in the separation unit the Particles are separated according to the set separation size, for example, the grain size or the Siebmaßes, from the contents. The contents fall through, for example, by the inventively provided double screen down and is immediately reinstalled in the artificial turf by falling through the bottom open double screen directly on the floor. The invention is not limited to the fact that the contents after the separation unit immediately falls back into the artificial turf pitch, as provided in a first variant of the invention, but it is also possible to dissipate the so treated (because separate) contents in such a container or to reinstall at a later date.

After the separation unit, a corresponding delivery option must also be provided for the particles separated from the contents. According to the invention, one or more conveying units are provided for this purpose, which convey the particles after the separating unit, in particular into a collecting area. The particles, usually corresponding dirt particles, paper, bags, but also leaves, etc., just what can rest on a sports field or artificial turf are collected accordingly in a collection area.

For this purpose, the invention also provides several different conveyor units according to the invention.

Usually the collecting area is designed as a dirt trough.

In a further variant of the invention it is provided that the collecting area is provided on the device, that is, the dirt pan is provided, for example, as an emptying drawer on the mobile device. It is also possible that the collecting area according to the invention on the towing device moving towing vehicle or a therefrom separate other vehicle, which mitfährt with the mobile device is located. As a result, if necessary, significantly larger collection areas can be realized.

As a conveying device for the particles, several variants are provided according to the invention. First, for example, a cross conveyor is provided. By means of a transverse conveyor, for example a rotating conveyor worm with screws arranged in opposite directions, it is possible to collect the dirt accumulating, for example, in the side area of the mobile device, in a central area and to extract it centrally there, for example. By such an arrangement is therefore achieved that the dirt or particles are reliably removed from the device.

Normally, as a conveyor according to the invention but also an extraction system is provided, which sucks, like a vacuum cleaner, the dirt particles, etc. in a large sump. According to the invention, it is certainly provided that both groups of conveyors are combined with each other and, for example, first a transverse conveying (transverse to the direction of travel of the movable device) and afterwards a corresponding suction are combined.

In a preferred variant of the invention it is provided that a level indicator is provided by present in the separation unit filling material. Such a fill level indicator is preferably arranged, for example, at the end of the twin-wire, so as to indicate when too much filling material accumulates in the mobile device. In such a situation, the speed of travel of the device relative to the ground is then too high and therefore to be reduced in order to allow sufficient time for the product to be cleaned to fall back to the ground through the twin-wire screen. Finally, the arrangement is to be operated in such a way that the current is absorbed by the removal device. and the flow of product cleaned by the separation unit is the same.

In a preferred variant of the invention, a central drive for the rotation of the brush, the conveyor and / or the transport arrangement is provided. Usually, as it also provides a variant according to the invention, the mobile device is towed by a separate vehicle, for example a towing vehicle, a tractor or the like. Such tractors usually have a sufficiently strong engine, since the arrangement is usually dimensioned so that with this engine, other mechanical parts can be driven. For this purpose, a corresponding Zapfaufnähme for transmitting the torque is standardized and the central drive according to the invention has a coupling point in order to connect this to the drive of the device moving towing vehicle.

However, the arrangement of a central drive does not exclude according to the invention in any way that the individual elements, the brush and the conveyor or the transport arrangement, have independent drives. In a third variant, a separate, serving as a central drive motor is provided on the device along. This can be for example an electric motor or an internal combustion engine. From this centrally located engine is then transmitted in a suitable manner via appropriate gear or shafts, etc., the torque to the respective intended elements.

According to the invention, the mobile device as a towed device, for example by means of a towing vehicle, or as a self-propelled device, for example in a corresponding vehicle, feasible.

The inventive concept presented here is usually wise designed for a processing width of about 900 mm.

By counting also to the invention mobile separation device, which consists of at least two juxtaposed, mobile devices - as described - consists, the aforementioned advantages are taken over, but at the same time multiplies the processing width accordingly. The efficiency or the processing speed with the aid of such a separating device according to the invention increases considerably.

Cleverly provided in a variant of the invention of the movable separating device that the structure of the individual devices is symmetrical to each other, which, for example, in the middle, for example, in the first device on the left or in the second device on the right of the suction arranges, the central for both Devices is arranged on the towing vehicle.

The arrangement of the two devices must not be at the same height next to each other, they can with respect to the

Driving direction also be slightly offset side by side according to the invention.

In the drawing, the invention is shown schematically in one embodiment.

Show it:

Double screen according to Fig. 4a, 4b and 4c

In Fig. 1, the mobile device 2 according to the invention is shown schematically. It consists of a relatively long but compact, low-housing, which is movable over front wheels 21 and rear wheels 22 on the artificial turf. The preferred direction of travel is given by the arrow 20 (drawn here to the left). In the rear region 25, a corresponding connection arrangement, for example for a towing vehicle, is provided, since the embodiment shown here is implemented as a towed mobile device 2.

For easier control of the entire device 2, the front wheels 21 are rotatable about a vertical axis of rotation and therefore the entire arrangement can also be driven in curves.

The arrangement is such that the essential elements of the device 2 are arranged in a housing 23 and the height position of this housing 23 with its built-in parts relative to the front wheels 21 by the height adjustment 12 is variable. This results in a vertical adjustability, which is indicated by the double arrow 13. The height adjustment 12 is realized here, for example, as a handwheel. It can also be a motor drive. In the direction of travel 20 after the front wheels 21 closes in the housing 23, immediately after the height adjustment 12, first a removal device 1 at. This removal device 1 is realized in the embodiment shown here as a rotating brush 10 which rotates about the horizontal axis 11. The necessary drive is not shown for clarity. The circle of the brush 10 is slightly opposite the turf surface characterized by the connections of the tires 21,22. This engagement of the brush 10 in the artificial turf makes it possible to sweep out correspondingly discharged there from him contents. Due to the adjustability of the altitude by means of the height adjustment 12, this can be varied.

The direction of rotation of the brush 10 is, for example, here in the clockwise direction, whereby it follows that the lower portion of the brush, which engages in the artificial turf, in the same direction as the direction of travel 20. Filled out of the artificial turf with particulate particles is from the Brush transported in the upper region of the housing 23 and conveyed into the collecting area 33 of a downstream in the direction of travel 20 of the removal device 1 separation unit.

In the embodiment shown here, the separation unit 3 consists of a tilted double screen 30, the front fifth is provided approximately as a collecting area 33.

There is an adjustment flap 34 above the twin wire 30 is provided. This adjustment flap 34 is pivotable about a horizontal axis and extends over the entire width of the housing 23 or the movable device 2. This results in the possibility to adjust the size of the collecting area (that is, the longitudinal extent seen in the direction of travel). The position of the adjustment flap 34 thus ultimately determines the point of impact of the product conveyed by the brush 10 into the separation unit 3. This damper controls thus the delivery of the purified filling material with the aim to achieve the most homogeneous, uniform installation of the cleaned material.

The twin wire 30 is disposed inclined so that the catching portion 33 is higher than the end portion 301.

Furthermore, the twin-wire 30 can be set in vibration by the eccentric drive 300 in such a way that a transport arrangement for the filling material in the separation unit 3 results. In this case, the eccentric drive generates not only an up and down movement, but also a horizontal component of movement, whereby the resting on the double screen 30 filling material is pushed upwards and backwards. It follows, therefore, of course, a homogeneous distribution of the contents on the twin wire 30th

The exact structure of the twin wire 30 results in particular from FIGS. 4a to 4c. The arrangement is chosen so that the contents through the twin wire 30, if the opening width of the screen is correspondingly suitable to fall through and thus is immediately installed again in the artificial turf. On top of the twin wire 30 then appropriate particles, such as dirt, paper, leaves or other objects, whose diameter is greater than the separation size or the screen diameter, then remain. To dissipate this separated material from the material is a conveyor 5, which is inventively designed to be very variable.

In the exemplary embodiment shown in FIGS. 1, 2, a suction device 50 is indicated as conveying device 5. In fact, the fan of the turbine of the exhaust system 50 is not shown here. It is located, for example, on a towing device 2 trailing vehicle. Therefore, the exhaust system 50 here only includes the suction channel 52 which is surrounded by the housing 51. On the housing 51 is a corresponding Suction hose leading to the fan or the turbine, connectable. Of course, a fan can also be attached to the device as an alternative.

The housing 51, and thus the suction channel 52, expand, seen in the direction of travel, funnel-like. Through the openings 24 in the housing 23 (on top) of the mobile device 2 and through the openings 31 of the twin wire 30 so that air is sucked into the suction channel 52 and particles that lie on the twin wire 30, backwards, against the direction of travel 20th , transported. Not shown is the sump that collects these particles, dirt, debris, leaves, etc.

Alternatively, however, such a dirt trough could also be arranged in the region of the funnel-shaped housing 51.

In Fig. 3, the separation unit 3 is shown schematically in one embodiment. The separation unit 3 is realized here as a double screen 30. The double screen 30 consists of two superimposed screens 37, 38, which are movable in a certain manner relative to each other, this relative or displacement movement is indicated by the double arrow 32.

It is easy to see that the openings 31 of the separation unit 3 are square and the direction of the relative or displacement movement 32 of the two screens 37, 38 is parallel to one another to a diagonal of these square openings 31.

In Fig. 4a, 4b and 4c three different positions of the twin wire 30 are indicated, leading to different separation dimensions, as shown in Fig. 5a, 5b and 5c lead.

In Fig. 4a, a setting is selected, which gives the largest separation measure (here, for example edge length of the square 10 mm). A first screen 37 is fixedly disposed below the second screen 38. The first sieve 37 and the second sieve 38 are largely identical, in particular they have the same configuration of the respective sieve openings 39 and their webs 302. That is, the length and width of the lands 302 are the same. In the variant shown in FIGS. 4 a and 5 a, therefore, the second sieve 38 completely covers the underlying first sieve 37.

According to the invention an adjusting device 4 is provided on the mobile device, which is here for example a corresponding adjusting screw or a sliding clamp closure.

In Fig. 4b, the effect of the adjusting device 4 is indicated. The second screen 38 is slightly offset to the left along the arrow 32 and it emerges below the first sieve 37, filled out for clearer identification with black out.

It can clearly be seen that the opening 31 of the separation unit 3, which has indeed been defined in FIG. 5 a by the clear screen opening 39, is now reduced in FIG. 5 b to an edge length of 7 mm, cf. Opening 31 '.

In Fig. 4a, 5c, the separation measure or the resulting opening 31 '' has been reduced again with the help of the adjustment. The sieve opening 39 originally defined by the second sieve 38 is now completely divided into four, relatively small one openings 31 '', a web cross 303 of the first sieve 37 lies completely in the square sieve opening 39 of the second sieve 38.
