    10152025302adjust how much the soil should be leveled at according to the conditions on itindividual field and according to how much coarse material is present on the ground surface.
    If the leveling plates are set too high in relation to the ground surface,the furrows and ridges from the sticks of the last row will largelyremain. If, on the other hand, the leveling plates are set too low in relation tothe earth's surface, new grooves and ridges will be formed by the leveling plates.setting the leveling plates, however, requires that it be leveledthe soil is inspected, which is difficult to do from the tractor cab, then the currentthe surface is often about ten meters behind the tractor, and the driver'sobservation position is usually a few meters above the ground, which makes itdifficult to perceive the shape of the leveled earth. The driver must thereforestop the tractor and get out and behind the crew to inspect the format the leveled ground, after which the setting changes, the crew is driven forwarda paragraph and a new inspection is made. The procedure is repeated until acceptablesetting has been achieved, and possibly also on additional occasions, becausethe conditions may differ between different parts of a field.
    There is thus a need for solutions that can facilitate adjustmentof tillage tools, such as levelers, in an agricultural machine.
    SummaryOne purpose of this documentary is to alleviate or eliminate the problemswith known technology.
    A special purpose is to make it easier for a user to accomplisha desired surface smoothness.
    The invention is defined by the appended independent claims.
    Embodiments appear from the appended dependent claims and fromthe following description and of the accompanying drawings.
    According to a first aspect, an agricultural tool is provided extensivelyat least one soil cultivating tool, arranged to cultivate soil, over whichthe agricultural implement is moved. The agricultural implement includes a surface levelingsensor for sensing a surface roughness of said soil, when thisprocessed, as well as an indicator connected to the surface evenness sensorarranged to provide an indication of said surface smoothness.10152025303The flatness sensors are located behind the row of travel cabinetsare arranged to achieve the desired surface smoothness, seen in the direction of travel.
    By feeling the surface smoothness and providing an indication ofthis, it is possible even for a user who is at a distance fromthe cultivated soil to continuously perceive what surface smoothness isachieved. Alternatively, it is possible to feed the indication to a control unitfor controlling the tool in relation to the surface smoothness and / or forpresentation to the user.
    The agricultural implement may be of such a nature that, when used,produces at least two grooves running in one direction of travel, which are separated by oneridge, and wherein said surface smoothness sensor is arranged to sense oneheight difference between a bottom portion of one of said grooves and a top portion ofsaid ridge,By measuring the height difference between the bottom part and the top part,came a practically useful and intuitively understandable measure of surface smoothness.
    The surface roughness sensor may comprise first sensing means, arrangedsensing said bottom portion and other sensing means, arranged tosense said top portion.
    By having different sensing means for the bottom portion and the top portion, respectively,a simple and robust measuring device can be provided.
    The agricultural implement may further comprise a control unit, arranged toreceiving a signal from said surface smoothness sensor, and that based onthe signal provide an indication of said surface roughness to a userand / or to an external device, such as a processing device or actuator.
    By providing a control unit, a flexible system canachieved, which enables the treatment and presentation of collectedsensor data. åThe control unit may be arranged to provide a control signal forsetting a position of the tool.
    By allowing the control unit to provide a control signal for settingthe position of the tool, it is possible to provide an agricultural implement whichautomatically sets the correct tool position and thus maintains a desired onesurface smoothness.10152025304Furthermore, it is possible to integrate both sensing and control in onesingle control unit for the entire agricultural implement.
    The indicator may be arranged to indicate said surface roughness to oneuser.
    By providing an indication for the user, the user is givenability to decide if adjustment of the tool is necessary or not. Onesuch an indication is also suitable for simple agricultural implements, which already havean actuator for remote adjustment of tool height, and where you wish to supplementwith a sensor and indicating device.
    The surface smoothness sensor can comprise at least one contact-freedistance measuring unit.
    Contactless distance measuring units have a well-known function and are exposed torelatively little wear.
    Alternatively, or as a complement, the surface roughness sensor cancomprise abutment means, designed to abut the ground surface.
    Surface level sensors that use abutment against the ground surface canadmittedly be exposed to some wear and tear, but can on the other hand be done completelymechanical, which means that it is not necessary to electrifyagricultural tool.
    According to a second aspect, a method of tilling soil is providedby means of an agricultural implement comprising at least one tillagetool. The method comprises continuously sensing a surface evenness of the soil,after the soil has been worked, and to adjust one based on said sensingposition of the tool.
    Brief description of the drawingsFig. 1 shows a known agricultural implement, seen obliquely from behind.
    Fig. 2 schematically shows a system comprising a tractor 2 and oneagricultural implement 1, and a surface level sensor 20.
    Fig. 3 schematically shows a surface evenness sensor according to a firstembodiment.
    Fig. 4 schematically shows a surface evenness sensor according to a secondembodiment.10152025305Fig. 5 schematically shows a fully mechanical surface level sensor, which isbased on the second embodiment.
    Description of embodimentsReferring to Fig. 1, a known agricultural implement 1 is shown in the form of acultivator, which is intended to be pulled after one via a coupling device 3towing vehicles, such as a tractor 2. The agricultural implement 1 has a frame 12, aa plurality of cultivator pins 10 and a set of leveling discs 11, which arearranged at the rear, seen in the direction of travel of the agricultural implement F.
    Referring to Fig. 2, there is shown a system comprising a tractor 2 whichis connected to an agricultural implement 1, which has tillage tools 10,11, of which a rear row consists of special equalizers 11, and is provided witha surface roughness sensor 20 for detecting surface roughness to be describedin more detail below. lThe surface smoothness sensor 20 comprises a detector 21, and can be included in onesystem comprising a control unit 22, a presentation unit 23, ainput unit 24 and an actuator 25.
    Referring to Fig. 3, an embodiment is shown in which a non-contactdetector 21 is used. The non-contact detector can, for example, be usedultrasound, radar or laser light to measure the distance between the detector andground surface. Furthermore, the detector 21 may comprise first 21a and second 21b, respectivelydetectors. The first detector 21a may be arranged at a position whichis directly behind, for example, one of the rear row pins 10, formeasuring the distance to a bottom portion of a furrow formed by the pin 10. Thethe second detector 21b may be arranged at a position which is in the middlebetween two pegs, to measure the distance to a top portion of one of the pegsformed ridge.
    The difference 'between the dimensions of the first 21a and second 21b respectivelythe detectors indicate the surface smoothness.
    The detector 21, 21a, 21b may comprise a transmitter for radar, ultrasound orlaser light and a receiver for radar, ultrasound and laser light respectively. Suchdistance detectors are known per se and do not need to be described in more detail.10152025306For example, such ultrasonic detectors used asparking aids on cars are used.
    The transmitter and receiver can be integrated in a physical device,which may be arranged on one projecting from the frame of the agricultural machinearm. The arm can extend downwards towards the ground surface. The detectors 21a, 21b canbe arranged on each arm.
    It is also possible to provide a distance sensor based oncamera technology, such as stereo camera technology. Another option is touse a camera that detects a light pattern projected on the earth's surface.
    The control unit 22 may be arranged to receive signals from the variousthe detectors 21, 21a, 21b. The signals can be forwarded to the presentationthe unit 23, which presents these to the user, for example where hesitting in a tractor cab. In one embodiment, the signal may be presented in the form of aso-called diode stack, where the surface evenness is shown with lamps that are switched on and offselectively in relation to a zero position. The zero position can represent a flat earth surfaceor a predetermined surface smoothness. In another embodiment, the signal maypresented via a monitor, either in the form of a diode stack, as valuesor diagram. In such an embodiment, it is possible to show bothsnapshot (diode bar) and historical data / trend.
    Based on what is shown on the presentation unit 23,via the input unit 24, control an actuator 25 which sets the tool10, 11 mode. The actuator can be hydraulic, pneumatic, electric ormechanically operable. For example, the actuator may be of the type such as- occurs in the above-mentioned agricultural implements called TopDown.
    In one embodiment, input unit 24 and actuator 25 may be connectedto such a control unit 23. In such an embodiment, the input unit 24 andthe presentation unit 23 be integrated with each other, for example in shapeof a touch screen.
    In another embodiment, the input unit 24 and the actuator 25form part of a separate system, which is separate from a system that includesthe surface smoothness sensor 20, its possible control unit 22 andpresentation unit 23. For example, the input unit 24 and10152025307the actuator 25 be of the type shown in the aboveagricultural equipment called TopDown.In one embodiment, actuation of the actuator 25 and thus adjustment canof the tool 10, 11 is provided only via the input unit 24. Thiscan then be done after the user has observed that the presentation unit 23indicated a surface roughness that is undesirable.In another embodiment, activation of the actuator 25 and thusadjustment of the tool 10, 11 is accomplished automatically via the control unit 22,in response to the signal from the detector 21, 21a, 21b indicating a surface smoothnesswhich deviates from what is predetermined. In such an embodiment,the user is given the opportunity to set a desired surface smoothness, such as the control unit22 can work to maintain.
    With reference to Fig. 4, there will now be an embodiment which utilizesabutment against the earth's surface to be described. The surface roughness sensor 20 'comprises herea pair of trailing arms 201, 202, which have a respective free end, which is arrangedto abut against the ground surface and a respective attachment end, with whichthe trailing arms are attached to a yoke or a cross beam 203. The trailing arms 201, 201may be formed of a flexible material, such as plastic, rubber or sheet metal. Thecan be designed so that they obtain an elongated contact surface (eg 5-30 cm)towards the earth. The crossbeam 203 is in turn rotatable about a center of rotation 207relative to a base portion 204, which in turn is attached to the frame of the agricultural implement.
    The attachment of the trailing arms 201, 202 to the cross member can be adjustable toenable measurement at different widths. Alternatively, the length of the crossbeam can be- adjustable, for example through a telescopic function. According to another variant »the crossbeam and the towing arms can be interchangeable.
    As an alternative to the trailing arms, some form of wheels or slidesbe used.
    The crossbeam can be rotatably attached and equipped with an angle sensor,which in turn provides a signal to a controller 22 according to whatdescribed above. Angle sensors are known per se.
    Referring to Fig. 5, it is possible to provide a fully mechanicalsurface level sensor 21 'by connecting a pointer 205 to the crossbeam203 and arrange a fixed or adjustable reference 206 on the base part 204 or10152025308the framework of agricultural implements. By observing the position of the pointer 205 inrelative to reference 206, the user can determine whether the surface roughnessis in accordance with what is desirable or if it deviates from it.
    The user can then adjust the tool 10, 11, as described above.
    It will be appreciated that a large number of embodiments may be provided withinthe framework of the scope of protection defined by the claims. For examplean agricultural machine can be equipped with a single surface level sensor,whereby adjustment of all the tools of the agricultural machine can be made based onthe surface roughness sensor. INAccording to another embodiment, the agricultural implement may comprise two, threeor more sections, which may be side sections and / or longitudinalseparate sections, each section having a tool set and a,surface level sensor and wherein each section's tool set isindividually adjustable.
    Furthermore, sensing and adjustment for each individual toolachieved.
    It is further understood that the invention may be applied to the setting ofworking depth for tools 10, 11 in the form of cultivator sticks 10, harrow sticks, inserts (notshown), sticks support leveling tools (such as "Crossboard® sticks" -not shown), seed beetles (not shown), roll forming parts (not shown), finger plates,seed plates (not shown) or other plate tools and rakes (not shown).
    The invention is particularly provided for the adjustment of tools 11 which havea substantially smoothing function, and which are intended to smooththe soil surface after the soil has been worked by one or more tools 10 havingmainly loosening, plowing or cutting function.
    It is further understood that the invention can be used both on pureagricultural implements, and on combined tillage andfor example sowing or planting agricultural implements.
    The control unit can be of a simpler or more complex type. According to aembodiment, the control unit may comprise a processing unit, while it,according to another embodiment, may be substantially abolished. It is understood thatan electronic indication of the surface smoothness can be provided without a control unit,for example by a detector 21, 21a, 21b or angle sensor directly109produces a signal representing the height difference between the bottom portionand the top part.
    According to one embodiment, the control unit can be arranged onagricultural implement, and can also constitute a control unit for other functions ofagricultural tool.
    According to another embodiment, the control unit can be arranged onthe towing vehicle, and also constitute a control unit for other functions ofthe agricultural implement and / or the towing vehicle.
    The agricultural implement can be used in a method for tilling soil100, where the surface roughness of the earth 100 is continuously sensed immediately (iewith the same machine) after the soil has been worked, and there, based onthis sensing, the position of the tool is adjusted.
