Description

[0001] The invention relates to a soil cultivation device, in particular a lawn harrow, comprising a supporting structure on which a plurality of cultivation tines are arranged, wherein the cultivation tines are resiliently mounted relative to the supporting structure.

[0002] Soil cultivation devices, such as lawn harrows, designed for soil cultivation, such as combing lawns and leveling the soil to be cultivated, are generally known from the state of the art. Typically, the cultivating tines are spring-mounted relative to the supporting structure to allow for flexible response to unevenness or foreign material in the soil or resting on the soil to be cultivated.

[0003] For this purpose, a support structure is provided that accommodates the tilling tines or on which the tilling tines are arranged. In other words, the tilling tines can deflect relative to the support structure while tilling the soil, building up a spring force, and are then reset by the spring force. Depending on the spring force, the tilling tines are deflected more or less strongly from their basic position under a defined load. If, for example, the spring force is selected too high and the tilling tines are thus attached too rigidly to the support structure, this can have a negative impact on soil tillage and the service life of the tilling tines.

[0004] As the tillage tines are subjected to forces during soil tillage that place strain on them, they can become damaged, for example by breaking off, over the service life of the tillage device. On the one hand, this represents a comparatively high maintenance effort, as damaged tillage tines have to be replaced. Depending on how the tillage tines are connected, for example if the large number of tillage tines are made as a single piece or are attached together to the support structure, replacing a single tillage tine can be difficult or even impossible. In addition, it is necessary to locate the broken piece of the tillage tine, as this represents a foreign body on the soil to be tilled. As the areas usually tilled with this type of tillage device are comparatively large, finding a lost or damaged tine can be a difficult task.broken part of a processing tine can be very time-consuming.

[0005] The invention is based on the object of providing a soil cultivation device, in particular a lawn harrow, which is improved compared to the aforementioned device and in which the connection of the cultivation tines is improved in particular.

[0006] The object is achieved by a soil cultivation device having the features of claim 1. Advantageous embodiments are the subject of the subclaims.

[0007] As described above, the invention relates to a soil cultivation device, specifically a grass harrow. The soil cultivation device comprises a support structure on which a plurality of cultivation tines are arranged. The cultivation tines are spring-mounted relative to the support structure. Cultivation tines are understood to be, for example, rod-shaped elements, in particular made of metal, which protrude from the support structure in the direction of the soil to be cultivated. Due to the lack of support of the cultivation tines on the support structure, the cultivation tines can be deflected during soil cultivation depending on the surface being cultivated and can then return to their original position due to the spring force that builds up.

[0008] As already described at the beginning, the soil tillage device is used, for example, for leveling the soil to be tilled. Furthermore, particularly in the grass harrow design, the soil tillage device can be used as a harrow or brush for soil maintenance, for example, lawn care. In particular, the soil tillage device can be used for sports fields, such as soccer fields, golf courses, and the like. During soil tillage, the tilling tines can comb through the vegetation, such as grass or lawn, and comb out foreign substances or foreign bodies, especially residues, from the vegetation, such as leaves, dead plants, and the like.

[0009] Specifically, "thatch" can be removed using the soil tillage device. At the same time, aeration can be achieved in the soil being tilled. In addition to natural vegetation, such as grass or lawn, the soil tillage device can also be used on artificial turf. In particular, filler material arranged there, such as cork material or granules surrounding artificial turf, can be evenly distributed. Disturbed filler material, for example, can be evenly distributed and smoothed by the soil tillage device so that it lies precisely between the stalks. Another advantage of the described soil tillage device is weed control.

[0010] The invention is based on the finding that the processing tines are individually detachably fastened to the support structure at individual connection areas, wherein at least one processing tine has a spring section with at least two screw threads between a free end of the at least one processing tine and the connection area for spring mounting, wherein a securing element detachably connected to the support structure for securing the at least one processing tine passes through an opening delimited by the screw threads. Accordingly, it is proposed herein that the at least one processing tine, in particular the individual processing tines in the plurality of processing tines, is individually detachably fastened to the support structure. This has the particular advantage that the processing tines can be individually detached from the support structure and replaced with a new processing tine in the event of damage.

[0011] It is therefore not necessary for the multitude of tillage tines to be replaced or even to be removed if a single tillage tine is damaged. Instead, the damaged tillage tine can be individually removed from the support structure and replaced with an intact tillage tine. As described, each tillage tine can be individually connected to the support structure, for example by being screwed to the support structure. The free ends of the tillage tines can be aligned straight, for example parallel to a vertical axis of the soil tillage device. The tillage tines can, as described, be made of a metal, for example steel. The tillage tines can, in principle, have any thickness, although diameters between 4 mm and 5 mm have proven to be preferred.

[0012] It is further proposed herein that each processing tine or at least one processing tine has a spring section for spring mounting, which spring section has at least two screw turns and is arranged between the free end of the at least one processing tine and the connection area. The “free end” of the at least one processing tine describes the end with which the processing tine contacts the ground for soil processing or the end that faces the ground. In contrast, the end of the processing tine opposite the free end is detachably fastened to the connection area with the support structure. Between the two ends of the processing tine, the at least one processing tine has the described spring section, by means of which the spring mounting is achieved. The spring section can have at least two, in particular exactly two, screw turns.

[0013] Due to the described connection of the tilling tine, in particular by means of at least two screw threads, in particular precisely two screw threads, the free end of the tilling tine can execute a defined movement during soil tillage. In particular, the free ends of the tilling tines describe a circular or spiral movement, which is particularly advantageous for soil tillage. The tilling tines can in particular be spaced far enough apart from one another that the individual tilling tines do not touch one another even when the free ends of the tilling tines are executing the circular movement. Due to the described defined circular movement of the free ends of the tilling tines, each tilling tine covers a comparatively large area during soil tillage. The circular movement is carried out in particular around the vertical axis, i.e.For example, the circular area described by the machining tine lies parallel to the surface to be machined or perpendicular to the vertical axis.

[0014] Furthermore, the soil tillage device is provided with a locking element that secures at least one tilling tine, in particular all tilling tines, against loss. The locking element is releasably connected to the support structure and extends through the opening of the tilling tines defined by the screw threads. In other words, the locking element can be guided through the opening formed by the screw threads of each tilling tine of the same row, so that the tilling tines remain secured by the locking element.If a processing tine breaks off, for example between the spring section and the connection area, the part of the processing tine connected to the connection area remains secured to the connection area and the remaining part of the processing tine is not lost due to the securing to the securing element, but remains coupled to the securing element.

[0015] Advantageously, the securing element can be detached from the supporting structure to remove the broken portion of the processing tine, and the broken portion can be removed. Similarly, the connection area to which the broken portion of the processing tine is connected can be opened, and the broken portion removed. The remaining processing tines do not need to be removed from the supporting structure but can remain connected while the defective processing tine is replaced. A new processing tine can then be connected to the connection area on the supporting structure, and the securing element can be guided through the opening defined by the screw threads.

[0016] In particular, a rigid securing element can be used as the securing element, for example, a rod or a tube. Alternatively, a flexible securing element, such as a rope or a wire, is also possible. When using a rigid securing element, the securing element can, in addition to the previously described securing function, also limit torsion of the processing tines arranged on it. The securing element thus further stabilizes the movement performed by the processing tines.

[0017] In a further development of the soil cultivation device, it can be provided that the at least one cultivating tine is designed to execute a circular movement around its vertical axis upon contact with the soil, in particular with grass. As already described, the securing element and the spring section specifically permit a rotary movement of the free end of the cultivating tine, so that it can be deflected and its tip can describe a circular or spiral path. The described rotary or circular movement is particularly advantageous for soil cultivation, since the removal of foreign bodies, a leveling effect, and a uniformity can be achieved across a large area.

[0018] In the soil tillage device, it can further be provided that the securing element, in particular a tubular or rod-shaped one, is guided through a mounting opening in the support structure and has at least one locking device designed to releasably lock the securing element to the support structure. As the locking device, a screw can be used, for example, which is screwed or can be screwed into an outer surface or outer wall of the securing element. When the locking device is screwed or locked, the support structure cannot be moved through the mounting opening, but is accordingly secured or locked to the support structure. If the locking device is released, for example the screw is unscrewed, the securing element can be passed through the mounting opening and thus released from the support structure.A damping device, such as an O-ring, can be provided between the locking device and the support structure. The damping device protects the support structure, in particular a painted surface of the support structure, from direct contact with the locking device.

[0019] As already described, the soil tillage device has a plurality of tillage tines. The tillage tines can be arranged in different rows. In one embodiment, a distance between two tillage tines in the same row can be between 5 cm and 15 cm, in particular between 8 cm and 12 cm. The described distance lies between two tillage tines in the same row, i.e. thus transverse to the direction of travel in which the soil tillage device is moved for soil tillage. The defined spacing of the individual tillage tines in the same row ensures that each tillage tine can perform the described movement during soil tillage, in particular can move in a circular or spiral manner with its free end.

[0020] According to a further embodiment of the soil tillage device, the soil tillage device can have at least two, in particular six, rows of tillage tines, wherein the tillage tines of two different rows have a defined pitch, in particular between 5 mm and 15 mm. For example, two tillage tines in adjacent rows of the soil tillage device in the longitudinal direction, i.e., in the direction of travel of the soil tillage device, are not arranged exactly one behind the other, but have the defined pitch.

[0021] For example, in the longitudinal direction of the tillage device, the tilling tines of a subsequent row are offset from the preceding row by a 12 mm line spacing. This means that the individual tilling tines of the tillage device in the different rows are not arranged exactly one behind the other in the longitudinal direction, but rather have a defined line spacing, and the tilling tines are thus offset from one another in the transverse direction. This advantageously allows the areas of the individual rows worked by the tilling tines to not be arranged identically one behind the other, but rather to be offset from one another by the defined line spacing. This further improves the removal of foreign matter, leveling, and uniformity.

[0022] The soil tillage device can further be developed such that the soil tillage device has at least one support wheel that is height-adjustable by means of a height-adjusting device of the soil tillage device, which support wheel is arranged in particular in the transverse direction of the soil tillage device within the working width of the soil tillage device. In the embodiment, it is provided that a height-adjustable support wheel can be adjusted by means of a height-adjusting device and the working height of the support structure and thus of the tillage tines arranged on the support structure can be adapted. In other words, the height at which the tillage tines are moved above the ground is set via the height-adjusting device. In particular, the soil tillage device has two height-adjustable support wheels. In particular, each height-adjustable support wheel can be adjusted via its own height-adjusting device.

[0023] The at least one height-adjustable support wheel can be arranged in the transverse direction of the soil tillage device within the working width of the soil tillage device. For example, at least one row of tillage tines can have fewer tines or a smaller extension in the transverse direction, thus providing a recess in the support structure for the arrangement of the at least one support wheel, in particular two support wheels, on the opposite sides.

[0024] In one embodiment of the soil cultivation device, the described height adjustment device can have a spindle drive with a measuring scale. Specifically, both support wheels can have such a height adjustment device or be height-adjustable with such a height adjustment device. Advantageously, this makes it possible to set a desired height for the support wheel using the measuring scale. In particular, this facilitates the height adjustment for both height-adjustable support wheels, since the same value can be set for both support wheels on the measuring scale.

[0025] The measuring scale can also be used to correctly adjust the working height. The working height can be adjusted so that the tilling tines just touch the surface of the soil to be tilled, but no tilling tines are inserted into the soil. This protects vegetation, such as shallow-rooted grass, from overly aggressive tillage with the tilling tines. For example, a test pass can be carried out over a defined length of the soil to be tilled to determine the intensity of tillage. Based on the test pass, the height of at least one support wheel can then be adjusted or set.

[0026] The soil tillage device can further be provided with a brush module that is adjustable independently of the tillage tines and comprises at least one brush for tilling the soil. Advantageously, a brush module that is arranged, for example, longitudinally behind the tillage tines in the direction of tillage or travel of the soil tillage device can thus be adjusted with respect to its working height independently of the working height of the tillage tines. Thus, independent adjustment of tillage tines is proposed, for example, via the height adjustment device of at least one support wheel. Independently of this, the brush adjustment device can be used to adjust the height at which the brush is guided over the soil to be tilled.

[0027] Depending on the type of soil cultivation or the subsoil, a suitable setting for the cultivating tines and, independently of this, a suitable setting for the brush can be selected. The brush module can, in particular, be designed to be detachable, so that it can be coupled to the support structure as needed and used together with the rest of the soil cultivation device. It is also possible to remove the brush module and use the soil cultivation device exclusively with the cultivating tines. If, for example, only the brush is to be used, the height of the cultivating tines can be raised using the height adjustment device until they are no longer in contact with the subsoil and are therefore inoperative.

[0028] The described brush adjustment device thus allows independent mounting of at least one brush module on the soil cultivation device, in particular the support structure. The brush adjustment device comprises, for example, a brush spindle drive with a brush measuring scale. Analogous to the previously described spindle drive with the previously described measuring scale, the brush measuring scale can also be used to set a defined working height for the brush or brush module via the brush spindle drive. Suitable working heights can, for example, be pre-measured and set on the respective measuring scale depending on the subsoil to be cultivated. For this purpose, a pre-measured table for working heights for the cultivating tines and / or for the brush module can be provided, for example.

[0029] In a further embodiment of the soil tillage device, the soil tillage device can have a hitch designed to couple the soil tillage device to a vehicle, in particular a tractor. The hitch can, for example, provide a 3-point hitch. This can, in particular, be standardized, for example, according to Category 0 or Category 1. In particular, the hitch can provide both a Category 0 receptacle and a Category 1 receptacle, so that the soil tillage device can be selectively coupled to different vehicles. Alternatively or additionally, for example via an adapter or a coupling, the soil tillage device can have a receptacle for a drawbar, pin coupling, and / or car coupling.If a drawbar, bolt coupling, or car coupling is used, at least one support wheel can also be used for transport. If a 3-point hitch is used, for example, on a tractor, the working height and inclination can also be adjusted via the hitch on the vehicle.

[0030] The invention is explained below using exemplary embodiments with reference to the figures. The figures are schematic representations and show: Fig. 1 a schematic diagram of a soil tillage device in a first perspective view; Fig. 2 shows a schematic diagram of a soil tillage device in a second perspective view; Fig. 3a a schematic diagram of a working tine of the soil tillage device; Fig. 3b a schematic diagram of a working tine of the soil tillage device; Fig. 4 a schematic diagram of a soil cultivation device in a side view; and Fig. 5 a schematic diagram of a soil tillage device in a top view.

[0031] Fig. 1 shows a soil cultivation device 1, specifically a lawn harrow, wherein the soil cultivation device 1 is generally designed for cultivating soil, specifically lawns. The soil cultivation device 1 has a support structure 2 on which a plurality of cultivating tines 3 are arranged. The cultivating tines 3 are resiliently mounted on the support structure 2. Specifically, the cultivating tines 3 are each individually detachably fastened to the support structure 2 by a connection area 4, for example by means of a screw. At the opposite end, each cultivating tine 3 has a free end 5, wherein between the free end 5 and the connection area 4, each cultivating tine 3 has a spring section 6 (cf. Fig. 3a, Fig. 3b).

[0032] Due to the at least two screw turns, in particular exactly two screw turns, in the spring section 6, a particularly advantageous movement of the free end 5 is possible, namely a circular movement or spiral movement of the free end 5 around the vertical axis of the soil tillage device 1. As can be seen, several rows of tillage tines 3 are arranged on the support structure 2, wherein the tillage tines 3 of each row can have a spacing 7, for example between 5 and 15 cm, in particular 12 cm. With regard to the arrangement of the tillage tines 3 in the individual rows, these have a line spacing 8, so that the individual tillage tines 3 are not arranged exactly one behind the other, but are offset by the line spacing 8 in the transverse direction of the soil tillage device 1. The line spacing 8 can, for example, be between 5 and 15 mm, in particular 12 mm.

[0033] Furthermore, two support wheels 9, 9' are arranged on the support structure 2, each via a height adjustment device 10, 10'. The height adjustment devices 10, 10' have, for example, a spindle drive, with a measuring scale 11, 11' arranged on a section of the height adjustment device 10, 10'. This makes it easier to adjust the working height of the processing tines 3. For example, each support wheel 9, 9' can be adjusted to the required height using the associated height adjustment device 10, 10', for example using the measuring scale 11, 11' provided by each height adjustment device 10, 10'.

[0034] For example, Fig. 1, Fig. 2, the support wheels 9, 9' are arranged within the working width of the soil tillage device 1, i.e., viewed in the longitudinal direction, tillage tines 3 are arranged in front of the support wheels 9, 9'. The rows of tillage tines 3 located between the support wheels 9, 9' are shorter than the rows of tillage tines 3 arranged in the longitudinal direction in front of the support wheels 9, 9'. In principle, the number of rows and the number of tillage tines 3 per row, i.e., the spacing 7 and the line spacing 8, can be selected as desired.

[0035] In addition, for example in Fig. 1, Fig. 2, Fig. 4, Fig. 5, a brush module 12 is shown, the working height of which can be adjusted via a brush adjustment device 13. The brush module 12 has at least one brush 14, in the illustrated embodiment, two brushes 14 arranged one behind the other in the longitudinal direction and extending in the transverse direction. The brush adjustment device 13 has a brush measuring scale 20. Using the brush measuring scale 20, the working height for the brushes 14 can be set or read.

[0036] As can be seen, the brush module 12 with the brush adjustment device 13 is arranged on the support structure 2. This allows the working height for the brushes 14 to be adjusted independently of the working height of the processing tines 3. The brush adjustment device 13 also allows the working height to be adjusted on both sides, so that the brushes 14 can have different working heights in the transverse direction. To adjust the working heights, for example, the working height for the processing tines 3 can first be adjusted, namely via the height adjustment device 10, 10', whereby the height of the support wheels 9, 9' can be adjusted. This can be done, for example, using the measuring scale 11, 11'. The brush module 12 can then be adjusted using the brush adjustment device 13 so that the brushes 14 are arranged at the desired working height.

[0037] The brush module 12 can also be completely detached from the soil cultivation device 1, so that the brushes 14 and brush adjustment device 13 can be dismantled and the soil cultivation device 1 can also be operated without the brush module 12. If, however, only the brushes 14 are to be used and no cultivation is to be carried out using the cultivation tines 3, the working height for the cultivation tines 3 can be selected such that they have no contact with the ground and, instead, the working height for the brushes 14 can be adjusted so that they carry out the desired soil cultivation.

[0038] The soil tillage device 1 additionally has a hitch 15, which is generally designed to couple the soil tillage device 1 to a vehicle, for example, a tractor. Optionally, the hitch 15 of the soil tillage device 1 has various interfaces for coupling the soil tillage device 1 to different mounts on the vehicle or to different vehicles.

[0039] For example, an interface for Category 0 and an interface for Category 1 are shown. An interface for a drawbar or bolt coupling or a trailer coupling is also shown. The towing device 15 can have the various interfaces in combination, allowing any desired coupling to different vehicles. The drawbar or bolt coupling or trailer coupling can be removed, for example, if a coupling using the interfaces for Category 0 or Category 1 is to be used.

[0040] For example, in Fig. 4 shows that the processing tines 3 of each row of processing tines 3 are secured to the support structure 2 with a common securing element 16. As already described above, the processing tines 3 are connected to the support structure 2 at the connection areas 4, for example by means of a screw. In addition, the securing element 16 extends through the openings 17 (see Fig. 3a, Fig. 3b) of the processing tines 3, in particular the spring section 6. In other words, the securing element 16 is guided through these openings 17, i.e., through the two screw turns of the spring section 6 of each processing tine 3 of the same row. As already described, the double spring turn or the at least two screw turns enables a defined elasticity and stability of the processing tines 3.

[0041] If a processing tine 3 is damaged so that the processing tine 3 breaks off, in particular between the connection area 4 and the spring section 6, a part of the processing tine 3 remains attached to the support structure 2 with the connection area 4. The remaining part of the broken processing tine 3 is secured by the securing element 16 so that this part is not lost. The securing element 16 can basically be designed as desired, although a rod-shaped or tubular securing element 16 may be preferred. In particular, a rigid securing element 16 can provide additional stabilization of the processing tines 3, in particular against torsion, so that the movement of the processing tines 3 can be carried out particularly advantageously.

[0042] The securing element 16 or each securing element 16 can be locked to the support structure 2 with at least one locking device 18. For example, a screw inserted into an outer wall of the securing element 16 can be used as the locking device 18. The locking devices 18 protrude beyond the outer wall of the securing element 16, effectively preventing the securing element 16 from leaving a mounting opening 19 in the support structure 2 when the locking device 18 is locked.

[0043] If one of the processing tines 3 needs to be replaced, for example because it has broken between the connection area 4 and the spring section 6, at least one locking device 18 of the securing element 16 on which the broken processing tine 3 is arranged is released. In the released state of the locking device 18, for example the screw is unscrewed, the securing element 16 can be moved through the holder opening 19. The securing element 16 can be moved transversely until the processing tine 3 to be removed is released, i.e., until the securing element 16 is removed from the opening 17 of the spring section 6 of the processing tine 3.

[0044] Likewise, the connection area 4 of the processing tine 3 to be removed can be detached from the support structure 2. Subsequently, a new processing tine 3 can be connected with its connection area 4 to the support structure 2 and the securing element 16 can be guided through the opening 17 of the new processing tine 3. Subsequently, the securing element 16 can be inserted into the Fig. 5, and the locking device 18 can be locked again, for example by screwing in the screw. A damping device, for example an O-ring, can be provided between the locking device 18 and the support structure 2, so that a surface, in particular a painted surface, of the support structure 2 can be protected.

[0045] An example is Fig.4 also shows an optional inclination adjustment device 21. The inclination adjustment device 21 is designed to adjust the inclination of the illustrated drawbar 22.

[0046] The advantages, details and features described with reference to the individual embodiments and figures can be combined with one another as desired, are interchangeable and transferable to one another.
