Description

The invention relates to a method for the care or restoration of an, in particular low-nutrient, green land area, preferably a lean turf area, and to an area maintenance vehicle for carrying out the method.Corresponding methods for the care or restoration of such surfaces are fundamentally known from the prior art. Thus, for the care of such surfaces, a targeted cut-back or a removal of fouling which is undesirable for the target surface is carried out manually using motors or other hand tools. This is effected in particular manually and without the use of a vehicle of whatever type, if the vehicle-supported use is not possible due to the nature of the ground and / or due to a steep slope. In particular heavy vehicles may cause an undesirable deterioration of the surface of a greenland, e.g. a grass scar. Lighter vehicles may have an unfavourable weight distribution and / or an insufficient cutting device for cutting back the fouling.US 4 338 985 A describes a machine for the wooding and clean crushing of trees and breasts located in the travel path of the machine.

The object is further achieved by a method for caring for or restoring a green land area according to claim 19. The claims dependent on this relate to possible embodiments of the surface maintenance vehicle.The invention relates to a surface maintenance vehicle for the maintenance or restoration of a, in particular low-nutrient, green land area, preferably a lean turf area, comprising (a) a cutting device for separating, in particular wood-like, fouling from the existing or future or to be restored green land area and (b) a conveying device for conveying fouling separated by the cutting device from the existing or future or to be restored green land area into a collecting device on the surface maintenance vehicle side. The surface maintenance vehicle can be designed, for example, as a manned or unmanned vehicle. The, in particular low-nutrient, green land area can be present, for example, as a low-nutrient lawn area or can be changed to such an area or restored to such an area. The target surface can preferably be designed as a, in particular low-nutrient, green land surface and / or as a, in particular low-nutrient, lawn surface and / or as a, in particular low-nutrient, lean lawn surface or lime-made stomach lawn surface or can be present or prepared as such after the treatment by means of the surface care vehicle.The green land area to be maintained or restored can also be referred to as agricultural areas on which predominantly grass and / or herbaceous plants are cultivated and whose biomass growth is utilized by breeding or mashing for livestock agriculture or slightly for producing energy plants (green landing). These are primarily esophageal systems created anthropogen, which require continuous use or care in order to prevent the growth of vegetation, in particular wood or forest, developing without counter-controlling measures. Natural protection areas are likewise referred to as greenland, in which the use claim is only secondary to not at all, but which aim at obtaining the character of these crop landscape elements and / or the animal and plant species bound thereto by means of corresponding natural protection measures.The green country can be present as pasture, meadow or their mixed forms or can be obtained or restored as such. If anthropogenic greenland is no longer used in central europe, it develops again over time into woods or forests as a result of natural sunsis. This is to be prevented by the method for caring for the green land area or using the area car or a development that has already occurred accordingly completely or in parts is to be reversed. The green land areas can be divided into natural green land, i.e. natural grass land produced (e.g. grastus, quits, savanna) and green land ecosystems caused by human activity. Consequently, the agricultural greenland can represent a secondary vegetation--created by human action--and thus a distinction from greenland in the narrower and broader sense. Meadows, pastures or mowers (madflures) can form greenland in the narrower sense. This green country in the narrower sense can also be referred to as a business green country or as a fatty tweigh or fatty pasture. These areas are generally mowed or rejected at least twice a year. Without this management or care in the climate of central europe, this form of the green country cannot exist. The method described herein and the surface maintenance vehicle described herein can enable this green country to be obtained or restored from surfaces already in sunny or in parts in a simple and economic manner.In the broader sense, green land comprises, in addition to the above-mentioned areas, also blight wines and pastures including alpine turf areas, wet wines, dry and semi-dry turfs, bristle grass turfs, leafhoppers, blow-by grass spreading wines and lime stomach turfs and seggenreeds. For the maintenance or maintenance of these surfaces or for their recovery from surfaces which are already in process completely or in parts, the method described herein and the surface maintenance vehicle described herein can represent an economically attractive and at the same time effective solution.In the Greenland, an erosion-protection function can also be fulfilled, in particular by its permanently closed plant covering. Because no treatment of the soil takes place, the formation of a rich soil life can result, in particular on perennial greenland. Thus, the Greenland offers not only erosion and groundwater protection, but also habitat for certain plant and animal species. The maintenance or the restoration of these functions is made possible in an economically acceptable and effective manner by the method described herein and by the surface care vehicle described herein.The cutting device provided on the surface care vehicle is configured such that, in intended use on the surface care vehicle, it carries out a severing of the, in particular arch-like, fouling. The severing can comprise cutting and / or chopping or the cutting device can comprise corresponding cutting (e.g. cutting device) or chopping (e.g. shredder) tools or cutting means. Alternatively or additionally, the cutting device can comprise a striking strip which contributes to the separation of the fouling and / or to the (pre)piking of separated fouling. In other words, a cutting edge and / or a grinding mechanism can be used as cutting means for separating and / or crushing the fouling by the cutting device. Consequently, the cutting device described herein can comprise a system designed as a cutting edge and / or as a grinding mechanism for separating and / or crushing the fouling.The fouling provided for separating from the greenland area or from an area to be developed again or for the first time in, in particular, low-nutrient greenland can be embodied, for example, in the manner of a wood, in particular can comprise wood. For example, the fouling separated by means of the cutting device consists at least partially of sweetening woods and / or grassy structures and / or herbous structures. It is possible for the surface-care vehicle to separate or cut off components of trees, strands and / or lians, at least in sections. The cutting device can be arranged on the surface maintenance vehicle in such a way that the fouling is separated at a defined height above the surface of the greenland surface or the surface to be redeveloped in greenland of not more than 50.0 cm, preferably not more than 25.0 cm, particularly preferably not more than 8.0 cm, most preferably not more than 5.0 cm. The fouling can also be separated off at a height of not more than 3.0 cm by means of the surface-care vehicle.During the use of the surface-care vehicle, it may prove to be advantageous that at least the surface-care is carried out if the floor moisture or the surface moisture does not exceed a defined value. A preferred use time is formed by the herb, in particular spether bst, or the summer, in particular spring summer and / or high summer, in these times the proportion of energy in the fouling is relatively high, so that by separating this fouling a relatively high amount of energy can be removed from the green land area, in particular from the lean turf area or the green land area to be restored, so that the growth of this region receives a recoil and thus the new growth is attenuated and any care intervals can be increased if necessary. Alternatively or additionally, the use time for carrying out the surface care vehicle-supported surface care method can also be outside autumn and summer, for example. In other words, the corresponding time planning of the deployment of the surface maintenance vehicle reduces the frequency of deployment thereof per unit area, since the new formation of fouling to be separated is reduced. Finally, sustained damage to the plant parts above the ground can be achieved in this way.An optional measure for influencing the formation of new fouling can be, for example, the arrangement of a dispenser device in or on the cutting device and / or in or on the surface maintenance vehicle. The dispenser device can be used directly or indirectly to apply a gaseous and / or liquid and / or solid substance to the green land area, in particular to the lean turf area, or to the green land area to be restored, which substance acts on this area in such a way that the formation of fouling, in particular the formation of fouling, is specifically influenced. For example, by means of the dispenser device, an aerosol (e.g. a nitrogen or a nitrogen binder) is applied to the greenland area, in particular to the lawn area, and thus the formation of fouling is specifically influenced or a specific influence is exerted on the remaining vegetation. The dispenser device can be arranged and / or oriented, for example, in such a way that the substance applied by it is applied at least in sections, preferably predominantly, particularly preferably completely, to at least one, in particular to all, cutting means. During the cutting or chopping, the substance located on the cutting means can act directly on the cut surface of the fouling remaining on the greenland surface or on the surface to be restored as greenland and thus has a high effectiveness with regard to influencing the plants to be treated (separated) in a targeted manner by the surface care vehicle. This consequently leads to a minimization of the substance used.The conveying device serves at least partially, preferably predominantly, particularly preferably completely, to convey the separated fouling from the location of the cutting (of the cutting device) to the collecting device. For this purpose, the conveying device can be configured to displace the separated vegetation at least in sections in a load-bearing manner in the direction of or into the collecting device. Alternatively or additionally, the conveying device can be configured to apply, at least in sections, preferably predominantly, particularly preferably completely, an impulse to the separated vegetation by the action of energy, in particular kinetic energy, originating from the conveying device, which impulse leads to a displacement of the separated vegetation towards the collecting device. The conveying device is preferably a device spaced apart from the cutting device. The cutting device can be supplied with energy, for example, independently of the cutting device and / or can act on the vegetation separated by the cutting device independently of the cutting device.By collecting the separated fouling in a collecting device and depositing it preferably at a location remote from the separation area of the fouling, it is achieved that the green land area, in particular the lean turf area, or the green land area to be recovered, is freed from the fouling and thus a basis of the nutrient supply, in particular the formation of natural humus, is extracted. In other words, nutrient formation from locally available or grown plant parts is prevented or at least reduced. This can contribute to the effective maintenance over a longer period of time of a more nutritionally low target situation or structure at the separation region of the fouling or the existing or to be restored greenland area. The interval for renewed covering of fouling or for renewed separation of fouling can thus also be enlarged.It is possible that a conveying channel extending at least in sections, in particular predominantly, from the cutting device to the collecting device is provided for conveying the separated vegetation. Preferably, the conveying channel is at least partially, in particular predominantly, formed as a tube channel having closed walls. The conveying channel can comprise, for example, a conveying channel body or tube channel defined in its three-dimensional shape by walls or wall sections. The conveying channel body can be embodied in one or more parts; in a multi-part embodiment, the conveying channel body comprises a plurality of conveying channel body segments which can be connected or are connected to one another to form the conveying channel body. Independently of the one- or multi-part embodiment, the conveying channel body comprises a conveying channel space; this is typically an inner conveying body volume bounded by corresponding walls or wall sections of the conveying channel body. The conveying channel body space functionally serves, at least in sections, conveying space for conveying separated fouling from the cutting device to the collecting device. Finally, the conveying channel body can be designed in such a way that an overpressure and / or underpressure generated by the conveying device and / or by the cutting device prevails at defined points of the conveying channel with as little pressure loss as possible or without loss of pressure.For example, a conveying device arranged at a distance from the cutting device can generate a negative pressure in the conveying channel space facing the cutting device, which negative pressure acts as far as into the cutting device and, if applicable, via the cutting device on a green land area lying directly above the cutting device or area of a green land area to be restored.The conveying channel can extend, for example, at least in sections, preferably predominantly, particularly preferably completely, from the cutting device via the conveying device to the collecting device. In this case, the conveying channel can be designed predominantly, preferably completely, as a closed channel. Alternatively or additionally, the conveying channel, in particular the conveying channel formed as a tube channel, can have, at least in sections, preferably predominantly, particularly preferably completely, a (a) constant or (b) a changing cross-sectional contour shape and / or cross-sectional area. In this case, the conveying channel can have an at least sectionally, preferably predominantly, particularly preferably complete, tapering of its cross-sectional area in the flow direction. The change in the cross section can have an advantageous effect on the flow conditions prevailing in the conveying channel and thus on the conveying of the separated fouling.The conveying channel can extend, for example, from a cutting device arranged in front of a driver's cab in the direction of travel at least as far as a region lying above an upper edge of the driver's cab and / or in the upper region of the driver's cab. The conveying channel can thus be arranged in front of the driver's cab on the surface-care vehicle side and guide or direct the separated vegetation via the driver's cab towards the collecting device. In this case, the conveying channel can extend, for example, at least as far as a region located above the driver's cab. It is also possible for the conveying channel to extend at least as far as a region lying in the rear half of the driver's cab, as seen in the direction of travel of the surface care vehicle. The conveying channel can extend, for example, as far as above the lowest point of a roof lining of the driver's cab, i.e. the conveying channel can also be integrated at least in sections into a roof of the driver's cab.The collecting device can be arranged or formed behind the driver's cab, for example, as seen in the direction of travel. The collecting device can comprise, for example, a receiving region which is located at least in sections, in particular completely, behind the driver's cab as viewed in the direction of travel. It is possible for the collecting device to comprise a guide section which extends at least in sections into the region above or above the driver's cab. The guide section can be oriented substantially horizontally, for example. The collecting device, in particular its guide section, can overlap with an outlet opening of the conveying channel in the projection onto the placement surface of the surface maintenance vehicle or viewed from the top view. In other words, the outlet opening of the conveying channel can cooperate with the guide section of the collecting device in such a way that the separated fouling emerging from the outlet opening of the conveying channel reaches the collecting volume. For this purpose, the guide section can comprise guide surfaces which are oriented such that a separated fouling meeting these guide surfaces is directed in the direction of the receiving region of the collecting device.According to the invention, the conveying device is designed as a flow generating device or comprises such a device. In this case, the flow generating device, in particular in a conveying channel, can generate a conveying flow, by means of which at least in sections a conveying of the fouling separated by the cutting device into the collecting device of the one surface maintenance vehicle can be carried out. The flow generating device can be designed, for example, as an engine and / or as a fluid energy machine. In this case, energy for driving a rotor can be supplied to the flow generating device, for example, wherein an overpressure and / or underpressure effect can be generated at interfaces of the flow generating device by the rotor movement. By the action of the overpressure and / or underpressure generated by the flow generating device, the separated fouling can be transferred to the collecting device at least in sections, preferably predominantly, particularly preferably completely. The conveying flow generated by means of the flow generating device can thereby form a gas flow which "entrains" the separated fouling. The flow generating device can be arranged, for example, downstream of and at a distance from the cutting device, wherein the conveying flow generated by the flow generating device enables extraction of separated fouling located at least downstream of the cutting device. For this purpose, a reduced pressure can be formed at corresponding points of a conveying channel. Alternatively, the flow generating device can be designed such that it generates an overpressure effective at least in sections in the conveying channel and conveys the separated fouling at least in sections by this overpressure. In a further embodiment, the flow generating device can be designed such that it generates a negative pressure in the direction of the cutting device, which negative pressure acts in the cutting device or through the cutting device on the cutting location of the green land surface in the cutting region of the cutting device. Thus, for example, growth lying loosely in the vicinity of the cutting device can be suctioned off via the cutting region of the cutting device. It is also possible to use a suction effect or reduced pressure acting by the flow generating device on the cutting region of the cutting device on the existing or to be restored land surface for aligning vegetation to be separated and thus have a positive effect on the cutting effect of the cutting device.A comminution device, in particular arranged or formed in or on the conveying channel and arranged downstream of the cutting device, can be used, for example, for comminution of the fouling separated off by the cutting device. Preferably, the comminution device-side comminution takes place before the separated fouling reaches the collecting device. In other words, a comminution device is arranged in a conveying channel downstream of the cutting device. This comminution device has the task of further comminution of the fouling which is supplied to it and separated off by the cutting device.The cutting device can be designed such that it separates and / or crushes the separated vegetation such that it has a maximum longitudinal extent of 400, preferably of 350 mm, particularly preferably of 320 mm. The cutting device can separate or break up the separated fouling in such a way that it has at least an average and / or maximum longitudinal extent of 100 mm, preferably of 140 mm, particularly preferably of 160 mm. Preferably, the growth is produced by the cutting device in an average or maximum longitudinal extent in the range from 100 to 350 mm, preferably from 140 to 350 mm.The comminution device can be configured such that it comminutions fouling separated from the cutting device in such a way that the fouling, after passing through the comminution device, has an average and / or maximum longitudinal extent in the range from 40 to 160 mm, preferably from 40 to 80 mm.The comminution device makes it possible to operate and / or design the cutting device in such a way that it allows a high speed of the surface maintenance vehicle during effective separation of the fouling and at the same time, owing to the weight of the cutting device kept low, allows a favorable weight distribution of the overall surface maintenance vehicle and thus the applicability of the surface maintenance vehicle, in particular in slope positions.For example, a cutting device as light as possible, in particular a shredder or a mulch head, can be used and thus the climbing capability (i.e. for example slopes greater than 25%) can be achieved. The weight of the cutting device results to a large extent in means for fulfilling the separating function, so that the weight of the means of the cutting device, which enable a transport function or a transport away of separated fouling, is kept low or reduced. This means that a portion, in particular a predominant portion, of the transport function for transporting the separated vegetation into the receiving device is carried out by the separate conveying device. The conveying device arranged separately from the cutting device and arranged starting from the cutting device in the direction of the vehicle rear, in particular the vehicle center, enables the conveying of the separated fouling into the collecting unit with a center of gravity at the same time located more in the center of the surface care vehicle. In other words, the cutting device is optimized for the separating function and the lowest possible weight, and the function of transporting away the separated vegetation into the collecting device takes over at least partially, in particular predominantly, the conveying device arranged more centrally.By further comminution of the fouling by this separation device, the density of the separated fouling arriving in the collecting device is increased and consequently a higher receiving capacity of the collecting device is achieved.In an advantageous embodiment, it can be provided that the conveying device and the comminution device are formed as one structural unit in a conveying and comminution device. In other words, a conveying and comminution device can be used which simultaneously carries out a conveying stream for conveying the fouling separated by the cutting device and a further comminution of the separated fouling during the carrying-through of the separated fouling by the conveying and comminution device. In an exemplary embodiment, the conveying and comminution device can be designed as a cutting and / or chopping turbine. In other words, the comminution device can be folded together at least with one component, in particular completely, with the conveying device-that is to say with the means which are causative of conveying the separated fouling into the collecting device-or can be designed as a unit.According to the invention, the surface-care vehicle has a track unit equipped with tracks (also referred to as a track belt). In other words, the surface maintenance vehicle can be equipped with a track drive. For example, the at least one track chain, in particular all tracks of the surface care vehicle, is at least partially, preferably predominantly, formed from a nonmetallic material, particularly preferably the track chain is at least partially, in particular predominantly, formed from plastic and / or rubber. The use of caterpillar tracks formed from plastic and / or rubber reduces the mechanical engagement with the ground or the existing or to be restored green land surface and is thus gentler. For example, a piste track can be used as a surface maintenance vehicle, wherein this piste track can be modified for summer operation. Thus, the snow crawler or the surface maintenance vehicle can comprise equipment device which enables sufficient cooling of the drive motor even at summer temperatures.The surface care vehicle can have, for example, a specific floor pressure of 0.098 to 0.260 kg / cm 2, preferably of 0.113 to 0.178 kg / cm 2, particularly preferably of 0.134 to 0.160 kg / cm 2. Alternatively or additionally, it can be provided that the specific floor pressure of the surface care vehicle is at most 0.280 kg / cm 2, preferably at most 0.200 kg / m 2, particularly preferably at most 0.180 kg / cm 2, most preferably at most 0.160 kg / m 2. For this purpose, the total weight of the surface maintenance vehicle including add-on parts (e.g. cutting device) and the contact surface, which is enlarged in particular by a track drive, can have a corresponding coordination or adaptation. The total weight of the surface-care vehicle, i.e. including the cutting device and conveying device and conveying channel mounted on the surface-care vehicle, can be in the range from 5000 to 15000 kg, preferably from 7000 to 13000 kg, particularly preferably from 9000 to 11000 kg. Alternatively or additionally, the maximum total weight of the surface care vehicle (with or without add-on parts such as, for example, a cutting device and / or a collecting device and / or a conveying channel) is 15000 kg, preferably 13000 kg, particularly preferably 11000 kg.The center of gravity of the unloaded surface care vehicle can be situated, for example, below the center of the central vertical axis of the surface care vehicle. The center of gravity of the unloaded surface care vehicle is preferably below one third of the central vertical axis of the surface care vehicle. The vertical axis is to be viewed as the central vertical axis through the, in particular geometric, center point of the surface maintenance vehicle. By configuring the vehicle such that its center of gravity is so low, the terrain clearance necessary for the present application can be achieved. In particular, the low and / or central center of gravity enables the surface care vehicle to be moved or maneuvered even in slope positions of greater than 25%, preferably greater than 35%.According to the invention, the cutting device is designed or set up in such a way that cull-like fouling of a maximum diameter of a maximum of 10 cm, most preferably of a maximum of 8 cm, can be separated from the existing or to be restored greenland surface. The diameter of the fouling indicated here means an average diameter of a fouling constituent to be separated, for example asts or strain, at the location of the cut. The average diameter can alternatively or additionally relate to the diameter lying in the section plane.The cutting device can be arranged, for example, on the vehicle front or in front of the vehicle front of the surface care vehicle in the direction of travel. For example, the cutting device is fastened directly to a vehicle structural component of the surface care vehicle or indirectly to the surface care vehicle by means of a holder. The cutting device can be located at least in the state of the intended use of the surface care vehicle at the vehicle front or, as seen in the direction of travel of the surface care vehicle, in front of the vehicle front of the surface care vehicle. In this case, the cutting device can be arranged or designed at least temporarily centered or offset with respect to the vehicle transverse axis.For example, a cutting device can be used which, in the use position, extends over at least 50%, preferably over at least 75%, particularly preferably over at least 85%, most preferably over at least 100%, of a width, i.e. length in the transverse direction of the vehicle) of the surface-care vehicle. In other words, an effective cutting region of the surface care vehicle can extend over the entire width thereof or over a part of the entire width. Thus, for example, a working width, i.e. effective separation region perpendicular to the vehicle longitudinal axis during the passing over the existing or to be restored green land surface, of the cutting device can be 1.00 to 4.00 m, preferably 1.20 to 3.00 m, particularly preferably 1.30 to 2.50 m, most preferably 1.60 to 2.10 m. Thus, the cutting device can be designed, for example, in the manner of a beam. The cutting device fastened to the surface care vehicle can be mounted movably, for example, in the transverse direction of the vehicle. Thus, for example, the cutting device can assume different positions in the transverse direction of the vehicle.At least one, in particular all, cutting means of the cutting device can have, in the use position, a maximum of 10 cm, preferably a maximum of 7 cm, particularly preferably a maximum of 3 cm, distance from a placement surface of the surface maintenance vehicle or from the surface of the existing or to be restored green land surface. Such a distance of the cutting means of the cutting device from the ground makes it possible to use a suction effect emanating from the conveying device as far as possible for transporting away or for suctioning off the separated vegetation. Due to the small distance, the flow conditions downstream of the cutting device are also positively influenced or a higher suction or suction effect is produced in the region between the cutting device and the conveying device.It is possible that the cutting device itself is configured via its direct attachment to the surface care vehicle and / or a holding device that secures the cutting device to the surface care vehicle in such a way that the distance of the at least one cutting means from the placement surface or from the existing or to be restored greenland surface can be changed in a targeted manner or can be held in a defined distance range. Preferably, the cutting device and / or a holding device holding the cutting device on the surface maintenance vehicle is designed such that a defined distance range can be held between at least one cutting means, in particular between all cutting means, the cutting device and the placement surface or the existing or to be restored greenland surface. It can also optionally be provided that the separation of the fouling takes place close to the soil, in particular to the soil plane. Close to the ground can be understood to mean a separation in a height range of at most 10.00 cm, preferably of at most 5.0 cm, particularly preferably of at most 4.0 cm, most preferably of at most 3.0 cm, above the ground edge or floor surface of the greenland surface. Here, attention may also be paid to the fact that the straw grain is not significantly damaged at least in sections, preferably predominantly, particularly preferably entirely, i.e. the fouling to be separated takes place as far as possible without destroying its rootwork or the rootwork of the fouling is as far as possible not pulled out.It is possible that a detection means, e.g. a distance sensor operating in a contacting and / or contactless manner, monitors the distance of the cutting device, in particular the distance of the cutting means, from the placement surface or from the existing or to be restored greenland surface. Preferably, an output signal of the detection means can be used to displace the cutting device, in particular to displace at least one cutting means, into a defined desired distance from the placement surface or from the existing or to be restored greenland surface. For this purpose, an actuator can be controlled which acts on the holding device and / or the cutting device in such a way that a specific change of the distance of at least one cutting means from the placement surface or from the existing or to be restored greenland surface is carried out. The detection means can be designed, for example, as a contact-type and / or contactless height pickup. For example, a continuous or interrupted scanning of the height takes place by carrying along a "sensor wheel" which is at least temporarily, preferably continuously, in contact with the existing or to be restored greenland surface or the installation surface and detects the distance between the cutting device, in particular the cutting body, and the surface and preferably outputs a signal representative thereof or a signal dependent thereon. This signal can be used to actuate an actuator for influencing the distance of the cutting device, in particular of the cutting body, from the surface of the existing or to be restored green land surface. For example, the signal is used to actuate a hydraulic controller or the signal is integrated into a hydraulic controller in order to carry out a specific change in the orientation and / or position of the cutting device, in particular of at least one cutting body, relative to the surface maintenance vehicle.The cutting device can have, for example, at least one rotating cutting means, wherein the cutting means can be rotated about an axis of rotation running substantially parallel to the vehicle transverse axis, i.e. transversely to the vehicle longitudinal axis. An alignment running substantially parallel to the vehicle transverse axis can comprise an alignment which encloses an angle of at most 45°, preferably of at most 30°, particularly preferably of at most 20°, of at most 10° between the axis of rotation and the vehicle transverse axis. In a highlighted optional embodiment, the axis of rotation encloses an angle of not more than 5° with the vehicle transverse axis. It can be provided that the cutting means rotates during the rotational movement in the use position in such a way that any point of the cutting means moves forward in the direction of forward travel from a lower low point or bottom dead point of the rotational movement. In other words, the at least one cutting tool rotates counter to a rotational direction of the track chain or of a wheel of the surface care vehicle resulting from forward travel of the surface care vehicle. Such a movement makes it possible on the one hand to achieve a sufficient separating action on the fouling to be separated and furthermore to apply a kinetic energy or a movement in the direction of the conveying channel and / or into the conveying channel to the separated fouling by the rotation of the cutting means. Consequently, a first path to be covered by the separated vegetation can be covered within the conveying channel starting from the cutting device, in particular by means of the energy introduced by the cutting means onto the separated vegetation.The surface care vehicle can be configured in such a way that it has a climbing capability of greater than 25%, preferably of greater than 30%, particularly preferably of greater than 33%, most preferably of greater than 35%. The indicated climbing capability specifies the slopes which the surface maintenance vehicle can safely handle on account of the engine power and on account of possible tilting moments acting on the surface maintenance vehicle. For example, the climbing capability can comprise a tilt angle which specifies the limit angle (i.e. tilt angle) of an inclined plane, when it is exceeded, a surface maintenance vehicle which is oriented with its central longitudinal axis at right angles to the falling line of the inclined plane tilts.The climbing ability can be influenced in that at least the drive unit of the surface maintenance vehicle, for example the internal combustion engine, is designed for operation in the specified steep positions. For example, its oil supply is designed in such a way that, despite the corresponding steep position, a sufficient amount of oil can be extracted from an oil pan. The surface-care vehicle can alternatively or additionally be designed such that it can be used at temperatures of -40° C. to 70° C., preferably -20° C. to 60° C., in particular the surface-care vehicle is equipped with a cooling circuit that is sufficiently effective for this purpose.It can prove to be advantageous if the weight distribution of the surface care vehicle is divided as follows or the surface care vehicle has a weight distribution indicated below: front third of the surface care vehicle to middle third to rear third of the total vehicle length, a weight distribution (proportion of the total weight of the surface care vehicle) of 0.3 to 0.6 to 0.2 to 0.6 to 0.2 to 0.4, in the case of a surface care vehicle provided with the add-on parts (e.g. cutting device, conveying channel, conveying and / or comminution device). In other words, for the surface-care vehicle, a weight distribution of the surface-care vehicle in terms of the total weight thereof can result as follows: (a) proportion of the front third of the surface-care vehicle ranges from 0.3 to 0.6, (b) proportion of the middle third of the surface-care vehicle ranges from 0.2 to 0.6, (c) proportion of the rear third of the surface-care vehicle ranges from 0.2 to 0.5.Alternatively or additionally, the center of gravity of the surface care vehicle can be located behind the rear half of the driver's cab, as seen in the direction of travel; preferably, the center of gravity is located behind the driver's cab. This can be achieved in particular by the conveying and / or comminution device, in particular a flow device, arranged as far as possible above the driver's cab or behind it.According to the invention, the conveying device or a comminution device, in particular the flow generating device or a conveying and comminution device, is arranged in a region between the front boundary of the surface maintenance vehicle without the cutting device and the rear of the surface maintenance vehicle. Due to the fact that the conveying device and / or comminution device fulfills a proportion, in particular a predominant proportion, of the conveying function for displacing the separated fouling from the cutting device to the collecting device, the centre of gravity of the entire vehicle can be positively influenced or placed more centrally by an arrangement of the conveying device and / or comminution device in the direction of the rear of the vehicle, in particular in the direction of the vehicle centre. Preferably, the conveying device and / or the comminution device, in particular the flow generating device, is arranged in a region between the front boundary of the surface maintenance vehicle and the geometric center of the surface maintenance vehicle.According to the invention, the conveying device and / or a comminution device, in particular the flow generating device, is arranged at least in sections, preferably predominantly, particularly preferably completely, above the first third of the height of the surface maintenance vehicle. In a further development, the conveying device and / or a comminution device, in particular the flow generating device, can be arranged above the second third, preferably above the third quarter, particularly preferably above the upper edge of the driver's cab. The displacement of the conveying and / or comminution device guided into the center or to the rear of the surface maintenance vehicle can positively influence the centre of gravity and the climbing capability of the surface maintenance vehicle.It can also optionally be provided that the conveying device is arranged or formed above the driver's cab of the surface maintenance vehicle. Thus, the conveying device, in particular the flow generating device, can form a cut surface with the driver's cab, as viewed in plan view, in particular can be contained completely in the surface of the driver's cab.It is possible for the conveying device to be supported directly or via a support bracket on or on the driver's cab. This reduces any vibrations generated by the mass and operation of the conveyor. It is also possible, for example, to reduce the strength and / or rigidity requirement, in particular with regard to fulfilling a load-bearing function) of the parts of the conveying duct, since the conveying device is carried by the driver's cab directly or via a support bracket connected to the driver's cab.The collecting device can be connected, for example, at least partially, movably on the surface maintenance vehicle. Preferably, a receiving region for receiving separated fouling is mounted movably relative to the remaining surface care vehicle. In an exemplary embodiment, the receiving region is tiltable relative to the surface care vehicle about a pivot or tilting axis. This tilting can be used to empty the separated vegetation from the receiving device. In this case, for example, a tilting automation system can be used, which enables automated or manual emptying by tilting the receiving region by actuators.In addition to the surface maintenance vehicle for maintenance or restoration of a green land area, the invention also relates to a method for maintenance or restoration of a green land area using a surface maintenance vehicle, in particular a surface maintenance vehicle described herein.The method for the care or restoration of an, in particular low-nutrient, green land area, preferably a lean turf area, comprises the following method steps: (a) separating, in particular archite-like, fouling from the existing or to be restored green land area by means of a cutting device of an area maintenance vehicle, in particular an area maintenance vehicle according to one of the preceding claims, and (b) conveying, in particular archite-like, fouling separated, in particular archite-like, from the existing or to be restored green land area by the cutting device by means of a conveying device of the area maintenance vehicle into a collection volume on the area maintenance vehicle side.All advantages, details, embodiments and / or features of the surface care vehicle according to the invention can be transferred to or applied to the method according to the invention.The invention is explained in more detail on the basis of exemplary embodiments in the drawings. The following shows: FIG. 1 shows a schematic illustration of a surface maintenance vehicle in a side view according to an exemplary embodiment; FIG. 2 shows a schematic illustration of a surface maintenance vehicle in a side view in a slope position according to an exemplary embodiment; FIG. 3 shows a schematic illustration of a surface maintenance vehicle in front view according to an exemplary embodiment.FIG. 1 shows a surface maintenance vehicle 1 for the maintenance or restoration of a, in particular low-nutrient, green land area 2, preferably a lean turf area, comprising (a) a cutting device 3 for separating, in particular arch-like, fouling 4 from the existing or to be restored green land area 2 and (b) a conveying device 5 for conveying fouling 4 separated by the cutting device 3 from the existing or to be restored green land area 2 into a collecting device 6 on the surface maintenance vehicle side. The cut-off vegetation 4 is conveyed in a conveying channel 7 via a conveying flow 12 and, after leaving the conveying channel 7, at an outlet end 28 of the conveying channel 7 into the receiving region 26 of the collecting device 6.The conveying device 5 can comprise a conveying channel 7 which extends at least in sections, in particular predominantly, from the cutting device 3 to the collecting device 6. The conveying channel 7 serves for conveying the separated fouling 4. the conveying channel 7 is preferably at least partially, in particular predominantly, designed as a tube channel having at least one closed wall.The conveying channel 7 can extend at least from a cutting device 3 arranged in front of a driver's cab 9 in the direction of travel 8, i.e. in the forward direction of travel, to a region lying above an upper edge 10 of the driver's cab 9 and / or in the upper region of the driver's cab 9, preferably the conveying channel 7 extends at least to a region lying above the driver's cab 9, particularly preferably the conveying channel 7 extends at least to a region lying in the rear half 11 of the driver's cab 9 as seen in the direction of travel 8 of the flat maintenance vehicle 1.The conveying device 5 can be designed, for example, as a flow generating device or can comprise such a device. Preferably, the flow generating device generates a conveying flow 12 by means of which at least in sections a conveying of the fouling 4 separated by the cutting device 3 into the collecting device 6 of the surface care vehicle 1 can be carried out.It is possible that a comminution device 13 is provided, in particular in or on the conveying channel 7 and downstream of the cutting device 3, for comminution of the fouling 4 separated by the cutting device 3. Preferably, the comminution device-side comminution takes place before the separated fouling 4 reaches the collecting device 6. Thus, the fouling 4 can be comminuted in two steps. First, the vegetation 4 is separated from the existing or to be restored green land 2 by means of the cutting device 3 and cut into large pieces (vegetation 4'). After the fouling 4' cut into large pieces has passed through the crushing device 13, the fouling 4'' is present in a reduced form or smaller pieces.It can be provided, for example, that the conveying device 5 and the comminution device 13, in particular the conveying device 5 designed as a flow generating device and the comminution device 13, is designed as a structural unit in a conveying and comminution device 14. In the embodiment shown in the figures, the conveying device 5 and the comminution device 13 are designed as a cutting and / or chopping turbine which forms a unit, wherein the latter carries out both a conveying stream 12 and comminution of the separated vegetation 4 passing through the latter.The surface care vehicle 1 shown in the figures has a track drive 16 equipped with at least one track chain 15. Thus, the surface care vehicle 1 basically has a structure similar or based on a snow grouser. Preferably, the at least one track chain 15 is at least partially, in particular predominantly, formed from a nonmetallic material, so the at least one track chain 15 can be at least partially, in particular predominantly, formed from plastic and / or rubber. A nonmetallic track chain 15 or a track chain 15 formed from plastic and / or rubber reduces the mechanical action of the surface maintenance vehicle 1 on the existing or to be restored green land surface 2.If a track chain 15 (also referred to as a track belt) is mentioned herein, this can comprise all design variants of a track chain 15, i.e. for example, that the track chain 15 can have links connected to one another or is formed at least in sections in one piece.The surface care vehicle 1 can be designed such that it has a specific floor pressure of 0.098 to 0.260 kg / cm 2, preferably of 0.113 to 0.178 kg / cm 2, particularly preferably of 0.134 to 0.160 kg / cm 2.The center of gravity of the unloaded surface care vehicle 1 can be situated, for example, below the center 18 of the central vertical axis 17 of the surface care vehicle 1. The center 18 of the central vertical axis 17 results from half the geometric height 29 of the surface care vehicle 1. the center of gravity of the unloaded surface care vehicle 1 is preferably below a third of the central vertical axis 17 of the geometric height 29 of the surface care vehicle 1. the geometric height 29 of the surface care vehicle 1 can relate to the maximum height of the surface care vehicle 1 with or without attachment devices (e.g. cutting device 3 and / or conveying device 5 and / or conveying channel 7). In FIG. 3, the height 29 of the surface care vehicle 1 is indicated, for example, as the height 29 including the maximum height extension of the mounted conveying channel 7.According to the invention, the cutting device 3 is designed such that it is suitable for separating or cutting wood-like fouling 4 from a circumference of at most 10 cm, most preferably of at most 8 cm.The cutting device 3 can be arranged on a vehicle front 19 or in front of the vehicle front 19 of the surface care vehicle 1 in the direction of travel 8. This allows the fouling 4 to be separated not to be compressed by the driving over with the surface care vehicle 1 before the separation process.It can prove to be advantageous if at least one, in particular all, cutting means 20 of the cutting device 3 in the use position have a maximum of 10 cm, preferably a maximum of 7 cm, particularly preferably a maximum of 3 cm, distance 21 from a placement surface 22 of the surface care vehicle 1 or are held in such a distance range. In other words, the distance 21 between the cutting means 20 of the cutting device 3 and the existing or to be restored green land surface 2 traveled over by the surface maintenance vehicle is a maximum of 10 cm, preferably a maximum of 7 cm, particularly preferably a maximum of 3 cm. This can allow e.g. a ground-level separation of the fouling 4 to be separated.The cutting device 3 can have, for example, at least one rotating cutting means 20, wherein the cutting means 20 is rotatable about an axis of rotation 24 running substantially transversely to the vehicle longitudinal axis 23. In this case, it can be provided, for example, that the cutting means 20 rotates in the use position about a rotational direction (see arrow 25) of the surface care vehicle 1 moving forwards or in the forward travel direction 8, as viewed from a lower low point. The at least one cutting means 20 thus rotates about the axis of rotation 24 in accordance with the direction of rotation of the arrow 25.The surface care vehicle 1 can be designed or configured in such a way that it has a climbing capability of greater than 25%, preferably greater than 30%, particularly preferably greater than 33%, most preferably greater than 35%. According to FIG. 2, the surface care vehicle 1 has a climbing capability of e.g. 35%, i.e. the surface care vehicle is able to climb up a ramp with a ramp angle α of 19.3°.An advantageous weight distribution of the surface care vehicle can be provided if the weight distribution of the surface care vehicle 1 is divided as follows: (a) the proportion of the front third of the surface care vehicle 1 is 0.3 to 0.6, (b) the proportion of the middle third of the surface care vehicle 1 is 0.2 to 0.6, (c) the proportion of the rear third of the surface care vehicle 1 is 0.2 to 0.5, The front third of the surface care vehicle relates here to the longitudinal section of the total length (including that which points toward the vehicle front or in the direction of travel 8. Add-on parts, such as cutting device 3 for example) of the surface maintenance vehicle 1.The conveying device 5, in particular the flow generating device, can be arranged, for example, in the region of the front boundary of the surface care vehicle 1 or in a region between the front boundary of the surface care vehicle 1 and the rear of the surface care vehicle 1. The weight of the conveying device 5 is thus displaced in the direction of the center and / or in the direction of the rear of the surface maintenance vehicle 1, whereby the climbing capability of the surface maintenance vehicle 1 is positively influenced. The front boundary of the surface maintenance vehicle 1 is understood in this context to mean the front end of the surface maintenance vehicle 1 without the cutting device 3. It is possible for the conveying device 5, in particular the flow generating device or the conveying and comminution device 14, to be arranged at least in sections, preferably predominantly, particularly preferably completely, behind the boundary 30 of the surface maintenance vehicle 1 without the cutting device 3.According to the invention, the conveying device 5, in particular the flow generating device or a conveying and comminution device 14, is arranged at least in sections, preferably predominantly, particularly preferably completely, above the first third of the height 29 of the surface maintenance vehicle. In a further development, the conveying device 5, in particular the flow generating device or a conveying and comminution device 14, can be arranged above the second third of the height 29 of the surface maintenance vehicle 1, preferably above the third quarter of the height 29 of the surface maintenance vehicle 1, particularly preferably above the upper edge 10 of the driver's cab 9.The collecting device 6 can be connected or designed, for example, at least partially movably on the surface maintenance vehicle 1. Preferably, a receiving region 26 for receiving separated vegetation 4', 4", or at least one or all wall sections defining the receiving region 26, is mounted on the surface maintenance vehicle 1 such that it can be pivoted via a pivot axis 27 to define the receiving region 26.In addition to the surface maintenance vehicle 1, the invention relates to a method for the maintenance or restoration of a, in particular low-nutrient, green land surface 2, preferably a lean turf surface, comprising the following method steps: (a) separating, in particular arch-like, fouling 4 from the existing or to be restored green land surface 2 by means of a cutting device 3 of a surface maintenance vehicle 1, in particular a surface maintenance vehicle 1 according to one of the preceding claims, (b) conveying, in particular arch-like, fouling 4 separated by the cutting device 3 from the existing or to be restored green land surface 2 by means of a conveying device 5 of the surface maintenance vehicle 1 into a receiving region 26 on the surface maintenance vehicle side.As can be seen in particular in FIG. 1, it can be provided that the conveying device 5, in particular the flow generating device or the conveying and comminution device 14, and / or the conveying channel 7 are connected or supported at least in sections, preferably predominantly, particularly preferably completely, via a support holder 31 with the surface maintenance vehicle 1. The support bracket 31 can be fastened, for example, directly on a vehicle base structure (e.g. chassis, supporting frame or the like) or on the driver's cab 9 and thus, starting therefrom, can perform an at least partially, preferably predominant, particularly preferably a complete or exclusive, supporting function for the conveying device 5, in particular the conveying and comminution device 14, and / or the conveying channel 7. For example, at least the channel section running downstream of a flow generating device or the wall elements forming this channel section is fastened at least predominantly, preferably exclusively, to the surface maintenance vehicle 1 via the support bracket 31, in particular exclusively via the driver's cab 9. The support bracket 31 can be used for at least partially, preferably for predominantly, particularly preferably for exclusively, supporting the conveying and / or comminution device 5, 13, 14 on a basic structure of the surface-care vehicle 1, in particular on a driver's cab 9 of the surface-care vehicle 1.The collecting device 6 can comprise, for example, a guide section 32 which extends from the collecting volume or receiving region 26 at least in sections into a region above or above the driver's cab 9. The guide section 32 can be oriented substantially horizontally, for example. The receiving region 26 can overlap with the outlet opening or the outlet end 28 of the conveying channel 7 in the projection onto the placement surface 22 of the surface maintenance vehicle 1. In other words, the outlet end 28 of the conveying channel 7 can cooperate with the receiving region 26 of the collecting device 6 and / or with the guide section 32 of the collecting device 6 in such a way that the separated fouling 4 emerging from the outlet end 28 of the conveying channel 7 reaches the receiving region 26.It can prove to be advantageous if the cutting device 3 is fastened to the surface care vehicle 1 by means of a holding device 33. The holding device 33 can be designed, for example, in such a way that a relative movement of the cutting device 3 and the surface maintenance vehicle 1 can be carried out by means of the holding device 33. For example, by means of a sensor signal or a manual intervention via an input device (not shown), the position and / or orientation of the cutting device 3 relative to the surface maintenance vehicle 1 can be changed. In a particularly advantageous embodiment, it can be provided that, via a control signal of a distance sensor, the distance 21 of the at least one cutting means 20 from the existing or to be restored greenland 2 or from the installation surface 22 is kept in a predefined range.FIG. 1 shows, by way of example, the arrangement and / or configuration of a scraper or of a feed element 34. This lead element 34 is located in front of the cutting device 3 in the intended direction of movement (direction of travel 8) of the surface maintenance vehicle 1. The lead element 34 interferes with or distributes animals, in particular small livestock, which are located on the green land area, so that at least the degree of any impairment of these animals by the cutting device 3 and / or by the surface maintenance vehicle 1 is reduced. For example, the front element 34 comprises at least one chain element, in particular a chain curtain, and / or at least one flexible element and / or at least one air flow, in particular an air curtain, which acts on the surface of the green surface lying in front of the cutting device 3. For example, the effective area of the feed element 34 is at least 30 cm, preferably at least 50 cm, particularly preferably at least 75 cm, in front of the cutting device 34.LIST OF REFERENCE CHARACTERS1 Surface maintenance vehicle 2 Green land surface 3 Cutting device 4, 4', 4"Fouling 5 Conveying device 6 Collecting device 7 Conveying channel 8 Direction of travel 9 Driver's cab 10 Upper edge of 9 11 Rear half of 9 12 Conveying flow 13 Comminution device 14 Conveying and comminution device 15 Caterpillar chain 16 Caterpillar drive 17 Central vertical axis 18 Center of 17 19 Vehicle front 20 Cutting means 21 Distance 22 Placement surface 23 Vehicle longitudinal axis 24 Axis of rotation 25 Arrow for rotation of 20 26 Receiving region of 6 27 Pivot axis 28 Outlet end of 7 29 Height of 1 30 Boundary front of 1 31 Support bracket 32 Guide section 33 Holding device 34 Front element α Angle
