Description

The present invention relates to a roller-shaped supporting device for a floor treatment apparatus resting on a floor, which comprises a plurality of injection elements for injecting a fluid into the floor, in particular turf, wherein the support means comprises an axis rotatable about a rotation axis and holding elements for fixing the axis at the soil treatment device.

In addition, the invention relates to a soil treatment device with a plurality of injection elements for injecting a fluid in a particular lawn having soil with a roller-shaped support means.

Soil treatment devices of the aforementioned type are for example in the DE 10 2015 115 991 A1 , of the DE 10 2016 105 248 A1 and the DE 10 2016 105 253 A1 described. The soil treatment devices are used for the care of the soil, for example, needle-shaped injection elements are used for injecting the fluid into the soil. Under the action of the fluid, in particular a pressurized gas or pressurized gas mixture, especially compressed air (in this case it is referred to as aerification), a loosening and thereby better aeration and drainage of the soil are achieved. Air and water are better able to penetrate the soil and the drainage effect is improved. For turfed grounds, such as sports or recreational facilities, the root system may spread better in the soil to promote growth.

Exemplary applications of the present invention are found in a soccer field including its edge areas (side and goal areas, coaching zones ...), a football field, a baseball field, a golf course that may include both the green and the fairway, or a turfed tennis court , Examples of leisure facilities are public parks, such as parks. It is also conceivable use of the soil treatment device described here in plantations, especially in orchards or viticulture.

The soil treatment device is advantageously suitable for fluid injection and in particular for aerification in soils with natural grass and hybrid grass.

The soil treatment devices described in the above references prove themselves in practice. In use, the soil treatment device is moved, for example by means of a towing vehicle in a machining direction. Via a lifting device, the injection elements are introduced into the soil and raised again after the fluid injection. Downstream in the machine direction, the roller-shaped bearing device is arranged on the soil treatment device and is moved over the portions of the bottom surface detected by the fluid injection, the bearing force being distributed as far as possible on the ground via the roller-shaped support device.

The object of the present invention is to provide a soil treatment device and a support device for these, wherein the result of soil loosening by fluid injection can be improved with the soil treatment device.

According to the invention, this object is achieved by a roller-shaped support device for a floor treatment apparatus resting on a floor, which floor treatment apparatus comprises a plurality of injection elements for injecting a fluid into the floor, in particular having turf, wherein the support means a non-rotatable axis or about an axis of rotation has rotatable axis, holding elements for fixing the axis of the soil treatment device and at least one surrounding the axis, deformable and rolling on the ground shell part, which includes or forms a flat contact area with the ground under load.

The support device according to the invention is designed roller-shaped and defines an axis of rotation, which is preferably aligned in the intended use transversely and in particular perpendicular to the processing direction of the soil treatment device. By way of the holding elements, the supporting device is held, for example, on a carrying device of the soil treatment device, wherein the carrying device comprises or forms, for example, a supporting frame. According to the invention, it is provided that the at least one casing part surrounds an axis (machine element) of the support device. About the at least one jacket part, the support device can roll on the floor. Under load, in particular the weight of the soil treatment device, the at least one casing part can deform such that it rests on a flat contact area on the floor. As a result, the pressure exerted on the floor by the support means is reduced as compared with a conventional floor treatment apparatus. Conventional soil treatment devices include, in particular, roller-shaped support devices made of a non-deformable material Metal. This results in a linear contact area on the ground. Under certain circumstances, in particular depending on the history of the soil and its degree of compaction, this may result in that after injection of the fluid, in particular compressed air, in the soil due to the linear contact area in conventional soil treatment devices a, albeit slight, compaction of the soil occurs and the Loosening effect is reduced. In contrast, it is found in the present invention in practice that by reducing the pressure on the soil due to the flat contact area a soil compaction is largely excluded after the fluid injection.

Since the at least one casing part is deformable, there is also the possibility of adapting the outer contour of the support device to the flatness or unevenness of the floor, which unevenness may well be desired - for example in golf courses. It can thus also be avoided by the invention that the soil is "flat rolled" with a desired degree of flatness.

Conveniently, the at least one jacket part is designed such that a planar or substantially planar contact region can be formed, over which the at least one jacket part rests on the floor.

In a preferred embodiment, it is favorable if the axle is or comprises a hollow axle, on the outside of which the at least one casing part is arranged, wherein the "outer side" can be understood in particular as the lateral surface of the hollow axle. The at least one jacket part extends along the outer circumference of the lateral surface and surrounds the hollow axle. Conveniently, the at least one casing part extends over the entire or substantially entire length of the hollow axle.

The at least one jacket part may preferably surround the hollow axle in a form-fitting manner and is preferably fixed in a force-locking manner to the latter, in particular by frictional engagement. In this way, a direct connection of the at least one casing part with the axis and in particular hollow axle is possible. Alternatively, an indirect connection to the axle and in particular hollow axle may be provided.

The axle advantageously comprises ends arranged on the hollow axle and connected with the rotatably connected flanges, which couple with the holding elements. At opposite ends of the axis, the flanges may be arranged, which may be rotatably or rotatably connected to the holding elements.

For example, it is provided that a respective flange is rotatably mounted about the rotational axis on a respective holding element. The holding elements can form bearing elements which are non-rotatably fixed, for example, on the support means. Relative to the holding elements, the axis can be rotated for rotation about the axis of rotation.

Alternatively or additionally, it may be provided that the holding elements are each rotatably connected to a respective first portion with one of the flanges and are fixed to a second portion of the soil treatment device, wherein the first portion is rotatably mounted about the axis of rotation on the second portion. A respective holding element can form a bearing element, wherein the first portion can rotate together with the flange and the hollow shaft relative to the second portion about the axis of rotation.

Overall, it can be provided that the support device comprises a rotatable about the axis of rotation axis or a non-rotatable axis.

In a preferred embodiment it can be provided that the axle is non-rotationally connected to the soil treatment device via the holding elements. It can therefore be provided a fixed axis.

It is advantageous, in particular in combination with the last-mentioned advantageous embodiment, if the support device comprises at least one rim associated with the at least one casing part, on which the at least one casing part is fixed and which is held rotatably on the axle via at least one bearing element. About the bearing element, a particularly low-friction mounting of the at least one casing part on the axis can be made possible. The use of the at least one rim, for example, allows the use of pneumatic tires for the at least one jacket part, which will be discussed below.

A preferred embodiment of the support device comprises, for example, a plurality of axially adjacent shell parts. The shell parts are conveniently designed identically.

A respective casing part may comprise or form a flat contact area with the ground when the support device rests on the ground under load.

Preferably, the support means associated with a respective shell part a Rim and at least one bearing element, via which the rim is rotatably supported on the axle. Shell parts and rims are advantageously configured identically. In particular, it can be provided that axially juxtaposed wheels are fixed on the axle.

Conveniently, the plurality of shell parts are fixed together on one axis and in particular hollow axle directly or indirectly. Alternatively it can be provided that the axis is divided into individual, axially adjacent and interconnected segments, which are assigned to a respective jacket part.

It proves to be advantageous if the shell parts are separated from each other releasably fixed to the axis. For example, it can be provided that the shell parts can be exchanged separately for the purpose of maintenance and / or repair. Conveniently, it is possible to solve the shell parts of one end side of the support device starting from the axis or starting from the end side on the axis.

It may be favorable if between adjacent shell parts at least on the outer circumference of the support means a gap is present, wherein the gap may be for example about 1 cm to 2 cm. In the case of a turfed ground, grasses in the region of the interspace are not or only to a limited extent captured and transferred by the support device when the tilling device is moved over the ground. This makes it easier for the machine operator to recognize which sections of the floor have already been grasped and run over by the floor treatment device when the floor - for example a soccer field - is successively traveled in adjacent tracks. In practice it turns out that in the presence of a small gap, the flatness of the soil is not affected.

It proves to be favorable if the at least one jacket part is profileless. In the present case, this is to be understood in particular as meaning that the at least one casing part has a smooth or essentially smooth texture on the outer circumference. In the below-mentioned use of a tire for the at least one casing part, for example, a so-called "slick" is used. Due to the absence of the profile no unevenness is introduced into the soil by the rolling support means. In conjunction with the areal contact area as even as possible load distribution without compaction of the soil.

The at least one jacket part expediently has a cylindrical outer contour or a substantially cylindrical outer contour. For example, the casing part is designed as a substantially vertical circular cylinder.

Preferably, the at least one casing part is made of a rubber material.

Depending on the purpose, it can be provided that different types of shell parts made of different materials, for example, with different rubber compounds, are kept. The shell parts may differ, for example, with regard to their deformability from each other, for example, load-dependent and / or temperature-dependent. This offers the user the opportunity to always select the ideal shell part for a soil treatment to be carried out.

Alternatively it can be provided that in combination with the soil treatment device, a plurality of different support means are held, which can be detachably connected for the respective soil treatment with the support device with regard to an optimal work result.

The at least one jacket part is designed in a preferred embodiment as a tire.

It proves to be advantageous if the at least one casing part is a pneumatic tire and a valve for filling with air is provided on a rim associated with the at least one casing part. In the present case, "air" is generally understood to mean a gas or a gas mixture, so that a filling of the at least one jacket part with a gas or gas mixture different from air can also be provided. As a result of the pneumatic tires, it is possible to adjust the pressure in at least one jacket part depending on the purpose so that an optimal processing result can be achieved. In particular, the size of the contact area and thus the pressure of the support device on the floor can be influenced via the air pressure.

In a preferred embodiment it can be provided that at least one cavity filled with fluid, in particular gas, is formed in the at least one jacket part. For example, for the at least one casing part, a hollow-chamber tire is used with a cavity which is closed on all sides by walls.

It can be provided that at least one cavity surrounding the axis is formed in at least one jacket part. For example, this indicates Jacket part on an inner wall which faces the axis and an outer wall, on the outside of the support device rolls on the floor. Sidewalls may laterally bound the cavity and, for example, adjoin an adjacent skirt portion.

There may be provided a plurality of cavities separated from one another by walls in at least one jacket part. The walls are in particular integrally formed by the jacket part.

The cavity or cavities is / are in a preferred embodiment of the support device advantageously radially bounded by extending in the circumferential direction of the axis of rotation walls and / or axially bounded by radially extending walls.

The gas in the cavity may be, in particular, air.

Alternatively or additionally, it may be provided that at least partially a liquid is received in at least one cavity. By means of the non-compressible liquid, the surface pressure can be evened out over the at least one contact area on the floor. The liquid is preferably biocompatible. It can be advantageous if a liquid of relatively high viscosity is used, preferably with a higher viscosity than that of water. An antifreeze fluid, such as glycol, may be part of or form the fluid.

In a preferred embodiment of the support device can be provided that the at least one casing part is at least partially formed like a sponge or porous.

In an implementation of the support device in practice, it proves to be advantageous if an axial extent of a respective shell part in the presence of a plurality of shell parts is about 5 cm to 25 cm, preferably about 10 cm to 20 cm.

In an implementation of the support device in practice, it proves to be advantageous if a diameter of the support device is about 20 cm to 40 cm, preferably about 25 cm to 35 cm.

It can be provided that the support device comprises a drive device, in particular in operative connection with the axle, by means of which the support device can be driven to rotate about the axis of rotation. Accordingly, the axle can act as a shaft, via which by means of the at least one casing part, a torque for moving the soil treatment device can be transmitted.

As already mentioned, the present invention also relates to a soil treatment device.

Advantageous embodiments of the soil treatment device result from advantageous embodiments of the support device according to the invention.

In the case of the ground treatment device according to the invention, the support device, with respect to the machining direction, is held downstream of the injection elements on the support device. In particular, the ground treatment device is in its intended use, in the processing direction behind the injection elements, only on the support means on the ground.

It may be provided that the soil treatment device upstream of the injection elements in the machining direction comprises a roller-shaped supporting device of the aforementioned type. In this way, a compaction of the soil before the injection of the fluid is largely avoided.

It is favorable if the at least one jacket part has, in a transverse direction transversely to the machining direction, an extension which is at least as great as the spacing of injection elements furthest spaced apart in the transverse direction, preferably larger than this distance. If fluid, and especially compressed air, is injected into the soil, there may be a slight elevation of the turf sod laterally, depending on the injection pressure and the state of compression occur the injection elements. By means of the support means, without tilling the soil and influencing the flatness, the turf sod slightly pressed again, thereby achieving a particularly good machining result.

At the bottom 12 it is, for example, the bottom of a sports or leisure facility, in particular a football field or a golf course. The lawn vegetation 18 may be a turf or a natural turf, but is also an insert of the device 10 conceivable with hybrid turf.

For the care of the soil 12 and to promote turf 18 is the device 10 provided with an advantageous soil loosening, improved soil ventilation, drainage and drainage effect can be achieved. This may cause the root system of turf 18 to promote growth better in the soil 12 spread.

It should be noted that the present invention is not limited to the application to a floor of the type described, this is only to better explain the invention.

The device 10 includes a support device 20 holding a support frame 22 having. The supporting frame 22 is formed for example of interconnected longitudinal and transverse members and / or other components. At the carrying device 20 can a disguise 24 be held, which can be configured like a box. In 1 is a left sidewall of the panel 24 hidden.

At a front 26 is on the carrying device 20 a coupling device 28 arranged over which the device 10 can be coupled to a towing vehicle, not shown in the drawing. A drive shaft 30 can couple with a PTO of the towing vehicle to work units of the device 10 drive.

Alternatively or additionally, it can be provided that the device 10 is self-propelled and / or that separate drive means are provided for the working units.

The device 10 is used to inject a fluid, in this case in particular air, into the soil 12 , For this purpose, the device comprises 10 a fluid supply device 32 comprising an air compressor, not shown, as well as lance shaped injection elements 34 , which are in fluid communication with the air compressor, for example via reservoir. Compressed air is the injection elements 34 fed and can over this in the soil 12 be injected.

The injection elements 34 are on a holding device 36 held and can by means of this relative to the support device 20 be moved in the longitudinal direction and also lowered and raised. This gives the possibility of a quasi-continuous cultivation of the soil, as for example in the DE 10 2015 115 991 A1 and the DE 10 2016 105 248 A1 to which reference is made in this regard.

In tillage the device becomes 10 in a machining direction 38 over the ground 12 emotional. Transverse and in particular perpendicular to the machining direction 38 is a transverse direction 40 aligned.

In the machining direction 38 the injection elements 34 upstream, the device has 10 a roller-shaped support device 42 on. The support device 42 is on the support frame 22 held immediately and one in the transverse direction 40 rotatable aligned axis of rotation.

In the machining direction 38 the injection elements 34 Downstream includes the device 10 a roller-shaped support device 44 , At the support device 44 it is a preferred embodiment of the support device according to the invention.

"Upstream" or "downstream" refers in the present case to a proper use of the device 10 in the machine direction 38 is moved. Sections of the floor area 16 be first from the support device 42 run over. Subsequently, compressed air is injected via the injection elements 34 in these sections of the soil 12 injected, whereby this is relaxed as explained above. Subsequently, the loosened bottom portion with the trailing support means 44 run over. The device is in intended use 10 only on the support facilities 42 and 44 on the ground 12 on.

The following is by reference in particular to the 2 . 3 and 5 on the design of the support device received.

The support device 44 defines a rotation axis 46 to which they are relative to the carrying device 20 is rotatable. The rotation axis 46 is in the transverse direction 40 aligned. In this case, there is no drive device for rotating the support device 44 intended. The rotation of the support device 44 takes place in the present case passively by rolling on the floor surface 16 due to the movement of the device 10 in the machining direction 38 ,

For holding the support device 44 includes the device 10 in the present case holding parts (a holding part 48 is in 1 shown), which on the support device 20 are directly or indirectly determined. In the present case, the holding part 48 with the in 1 Not shown side wall connected, in turn, on the support frame 22 is held.

As in particular from the 2 and 3 shows, includes the support device 44 an axis 50 , The axis 50 comprises a hollow axle 52 that the axis of rotation 46 defined and distinguished from a first end 54 to a second end 56 the support device 44 extends. The hollow axle 52 is cylindrical and has an outer side 58 on, which forms a lateral surface.

At the ends 54 and 56 includes the axis 50 one flange each 60 coaxial with the hollow axle 52 aligned and connected to this rotation. The respective flange 60 includes radially outside a hollow axis 52 overarching edge 62 , With the hollow axle 52 is the flange 60 for example via a screw connection 64 connected, with other types of connections are conceivable. Central points the respective flange 60 a passage opening 66 on.

The support device 44 includes holding elements 68 , A respective holding element 68 passes through the passage opening 66 with a first section 70 , where the flange 60 for example via a screw connection 72 rotatable with the first section 70 connected is.

The holding element 68 includes a second section 74 that is relative to the first section 70 around the axis of rotation 46 is rotatably mounted. The second section 74 is on the holding part 48 fixed, for example by screwing.

In operation of the device 10 rolls the support device 44 on the floor surface 16 from. The hollow axle 52 rotates via the non-rotatable connection together with the flange 60 and the first section 70 relative to the second section 74 , which in turn is non-rotatable on the holding part 48 is fixed.

Alternatively it can be provided that, for example, the flange 60 rotatably on the holding elements 68 is held, which are designed non-rotatably.

The support device 44 according to the invention comprises at least one axis 50 surrounding, deformable and on the ground 12 , especially its bottom surface 16 , rolling jacket part 76 , In the present case, the support device 44 a plurality of shell parts 76 on. The shell parts 76 are identical. In the present case, ten shell parts 76 intended ( 2 ).

The shell parts 76 are arranged axially next to each other and together on the hollow axle 52 established. Here are the shell parts 76 on the outside 58 arranged and surround the hollow axle 52 form-fitting. In addition, there is a frictional and in particular frictional connection of the shell parts 76 with the hollow axle 52 ,

A respective jacket part 76 is in this case made of an elastically deformable rubber material and in particular as a tire 78 designed. The mature 78 has inside a cavity 80 in the present case filled with gas and in particular air-filled. As mentioned above can be provided be that the cavity 80 at least partially filled with a liquid.

The mature 78 is accordingly a hollow tire, wherein the cavity 80 the hollow axle 52 surrounding in the tire 78 is formed. In the radial direction, the tire 78 inside one in the hollow axle 52 adjoining wall 82 on and radially outside a wall 84 , which is an outer wall of the tire 78 forms. In the axial direction is the cavity 80 laterally from side walls 86 limited, the sidewalls of the tire 78 form.

In the axial direction are the side walls 86 adjacent tire 78 to each other, and the outermost tires 78 are from the edges 62 flashed.

The tires 78 are profileless and radially outwardly designed substantially smooth. The tires 78 have approximately a cylindrical outer contour.

On the outer circumference of the support device 44 is between adjacent tires 78 in the passages from the walls 84 to the side walls 86 a respective gap 88 present, on the order of, for example, about 1 cm to 2 cm.

In a preferred embodiment of the support device 44 For example, an axial extent of a respective tire 78 be provided from about 10 cm to 20 cm and a diameter of the support device 44 from about 20 cm to 40 cm.

When unrolling the tires 78 on the floor surface 16 is due to the non-positive connection with the hollow shaft 52 the rolling motion on a rotation about the axis of rotation 46 as explained above.

The 5 illustrates the effect and operation of the support device according to the invention 44 compared to how an in 4 illustrated conventional support device.

Due to the deformability of the tires 78 under load due to the dead weight of the device 10 Forms on the ground at the overlay 12 a flat contact area 90 of the tire 78 , The contact area 90 In addition to the extension of the tire 78 in the transverse direction 40 an extension in and opposite to the machining direction 38 on. As a result, the weight of the device 10 at the support device 44 is divided over a relatively large area and accordingly the pressure on the ground 12 is comparatively low.

The contact region is preferred 90 planar or substantially planar.

The result of the compressed air injection in the soil 12 Occurring loosening is therefore when rolling the support device 44 not impaired. The support device 44 is constructed so that a compaction of the soil 12 can be largely avoided. Nevertheless, a slight pressure on one of the compressed air injection may be slightly off the ground 14 lifting lawn turf 92 possible.

Through the gaps 88 arise after driving on the ground 12 Areas with no or only slightly shifted grasses, which can be easily recognized by the machine operator. If the sports facility is successively traversed and processed in several lanes, it is easily recognizable to the machine operator which sections of the floor 12 already been processed.

In a conventional support device, in 4 with reference number 94 In contrast, a jacket is shown 96 provided of a rigid, non-deformable material, in particular of metal. This causes the coat 96 a linear contact area 98 on the ground 12 formed. This can lead to a degree of compaction that is inherently undesirable after the injection, in particular depending on the previous history of the soil and prior to the injection 100 in the ground 12 For example, lawn sod 92 gives (dense dotted area in 4 ). Such a re-compaction 100 can be avoided thanks to the invention.

6 shows in a schematic representation and with reference to the machining direction 38 and the transverse direction 40 an outer contour 102 the support device 44 and an outer contour 104 a portion of the holding device 36 at which the injection elements 34 are held. In the compressed air injection is a respective effectiveness area in the soil 12 achieved, which is a respective injection element 34 due to the spread of compressed air in the soil ( DE 10 2015 115 991 A1 ).

Based on 6 is recognizable that the tires 78 with each other in the transverse direction 40 have a greater extent than the distance from in the transverse direction 40 furthest spaced injection elements 34 , In particular, the support device protrudes 44 with the tires 78 each in the transverse direction 40 externally arranged injection elements 34 , This will ensure that the turf may be slightly raised due to the compressed air injection 92 in the transverse direction 40 even laterally next to the outer injection elements 34 from the support device 44 recorded and lightly pressed again, but without the ground 12 to condense.

The following will be in the 7 and 8th partially and schematically illustrated further preferred embodiments of the support device according to the invention received. For identical or equivalent features and components identical reference numerals are used. It is only on the main differences in relation to the support device 44 received. The achievable with this advantages can also be achieved with the support means mentioned below.

For example, the retaining element 68 a stop 122 to the concern on the holding part 48 have and thread 124 for screwing with a nut. Other fixations of the holding elements 68 at the holding parts 48 are of course conceivable.

Also with the support device 120 can the axis 50 a hollow axle 52 his.

As shell parts 76 are at the support device 120 also tires 126 provided for the training of pneumatic tires. A respective tire 126 is a rim 128 associated with at least one bearing element each 130 on the axis 50 is mounted rotatably. In the axial direction, the ensembles are made of tires 126 , Rim 128 and bearing elements 130 arranged side by side and to a certain extent wheels on the axis 50 , When unrolling the tires 126 on the floor surface 16 rotate the rims 128 relative to the axis 50 around the axis of rotation 46 ,

The tires 126 are made of an elastically deformable material and in particular rubber material. Between the tire 126 and the rim 128 is a cavity filled with air 132 educated.

It's a particular, on the rim 128 arranged valve 134 provided over which the cavity 132 can be acted upon with air. This gives the possibility, depending on the application, the air pressure in the cavity 132 adjust so that the contact area 90 on the ground 12 is set for an optimal treatment result.
