    10152025302the end position of the said adjusting part of the pivoting mechanism is varied torespective stops, whereby different working depths can be set. The hydraulicthe operation of the pivot mechanism admittedly allows a considerablemore comfortable adjustment of the working depth, but still the tractor driver muststep out, when an additional distance bit is to be inserted and a distance bit, respectivelyshall be removed, to implement a further change in the working depthin addition to the two preset end positions.
    The present invention therefore has for its object to provide aimproved tillage equipment of the type initially indicated,which mitigates the disadvantages of the prior art and in an advantageous mannerfurther develops the latter. Preferably, comfortable service should bepossible, which is sensitively adaptable to the ground conditions and even while drivingis possible to vary to different working depth settings atgrounding tool unit_This object is solved according to the invention by atillage device according to claim 1. Preferred embodiments ofthe invention is subject to the dependent claims.
    It is therefore proposed that for working depth setting ofthe ground engaging unit set the height of the trailing roller relativethe machine frame. The height of the trailing roller relative to the machine frame is herewithsteplessly adjustable by means of a pressure fluid drive device, so that even in working anddriving operation not only two end positions can be set, but arbitraryintermediate positions and thus arbitrarily finely varying working depths canset, without having to change spacers for this. According to the inventionprovided that the working depth adjusting device has arear height adjustment device for height adjustment of the rear rollerrelative to the machine frame, the saidthe rear height adjustment device has a stepless operationpush fl drive device as well as a control device for stepless adjustment ofthe said pressure drive device and thus steplessworking depth setting. The pressure fluid drive device can be stopped and set inarbitrary intermediate positions over its entire setting range, wherebyarbitrarily fine different working depths can be set. Preferably this is achieved10152025303the working depth adjustment of the engaging tools by adjusting the height ofthe trailing unit, whereby even in the presence of several rows withintervention tool no multiple mobility must be provided and a smoothchange and setting of the working depth of the severalthe intervention tool rows can be achieved.
    In a preferred further development of the invention, at least one can be usedpair of pressure medium cylinders for height adjustment of the backing roller bewhich pressure medium cylinders are connected to each other on a mainslave device mode. In particular, a master cylinder may be connected to onefirst pressure chamber with a connection to a pressure source, while aslave cylinder is connected to its first pressure chamber by the secondthe pressure chamber of the master cylinder, so that when pressure actuation ofthe master cylinder pushes pressure medium flowing out of its secondpressure chamber into the slave cylinder. With its second pressure chamber is the one mentionedthe slave cylinder is preferably connected to a reverse flow and atank connection. The two pressure medium cylinders are preferably hereconnected in parallel to each other, to drive the height adjustment device forheight adjustment of the trailing roller in parallel. This allows even largemachine widths are adjusted in height and working depth, respectively, evenly throughoutworking width.
    To achieve a favorable installation situation forpush the drive, without sacrificing a large setting path forthe height setting of the post-roll, it is in a preferred onefurther development of the invention provided that the actuator ofthe pressure fluid drive device is not immediately connected to the height-adjustablethe trailing unit, but acts on a control link, by means of which control linkthe rear unit is directly or indirectly connected to a height-adjustable unitthe machine frame. This indirect connection of the actuator atthe pressure drive device on the one hand allows the actuator to be arranged ona therefore favorable place in a favorable, especially protected and space-savingorientation. In a further development of the invention, the pressure medium cylinder maybe arranged in a horizontal orientation, substantially pointing in the direction of travel,wherein the pressure medium cylinder, regardless of its active connection with10152025304the rear unit can be placed slidably forward overthe ground engagement tool unit, the working depth of which is to be set.On the other hand, some over- or under-gearing can be achieved through itindirect coupling of the actuator of the pressure fluid drive device_In particular, for this reason, the guide joint can be designed in such a way that a link pointat the guide joint on the machine frame or an indirect or directly connected theretojoint support piece is located at a longer distance from a link point atthe trailing unit to the said control joint than fromthe link point of the pressure medium drive device on the said guide joint.
    The link points are thus preferably selected in such a way that the post-roll hasa larger lever on the guide joint than the pressure medium drive device, wherebyeven with only a limited setting path atthe pressure medium drive device a relatively greater adjustability ofthe aftermath can be achieved.
    In a particularly advantageous embodiment of the inventionthe follower roller be height-adjustable suspended on the machine frame by means ofat least one four-link control, in particular a parallelogram link control_ The saidthe parallelogram link control can in this case mainly consist of a link pair, whichcomprises two spaced apart, parallel to each othercontrol links, which are preferably about the same length and are aligned approximatelylying, in a center position regarding their turning path. Boththe control links are then preferably connected each with a link point onthe machine frame and with each an additional link point articulatedwith the aforementioned carrier of the trailing unit, on whichthe post-roll and possibly also that between the post-roll and theprevious grounding tool unit further providedthe engagement tool unit is suspended. The mentioned link points of theboth control links can in this case preferably in the said intermediate positionat the control link define the vertices of a rectangle.
    To allow a compact space-saving connection ofthe pressure fluid drive device, in this case one of the control links can be designed as oneturning lever, one leg of which is linked to the rear unit10152025305and whose other leg is connected to the actuator ofpressure fluid drive device_In a further development of the invention, in a preferred manner furthera ground gripping tool unit is set up between said at least oneground engagement tool assembly and post-roll, which furthergrounding tool unit is differently designed and can be specialdesigned as a row of discs. This additional, differently designedground engagement tool unit may preferably be suspended on a matthe after-roll together height-adjustable after-unit carrier, so thatthe aforementioned additional ground engagement tool assembly is included with aheight adjustment of the trailing roller relative to the machine frame and thusground engagement tool unit as runner. This is further designedgrounding tool unit in an advantageous manner as hollow discs, socauses these thereby independent of the present setthe working depth of the extending pin row and pin rows one evenlypermanent surface treatment of the soils thrown up by the cultivator sticks.
    To still enable an adjustment of the working depth of itsaid additional grounding tool unit, this is in afurther development of the invention is preferably suspended height-adjustablesaid carrier of the follower unit, so that said furtherthe ground engagement tool unit is height-adjustable independently of the previous onecontinuous ground engagement tool unit relative to the post roller and / or hasan adjustable working depth.
    The pressure fluid drive device for height adjustment of the post roller canin principle be differently designed. For example, a hydraulic swing motor wouldconsidered in a pivotable suspension of the post-roll. Preferablyhowever, the pressure fluid drive device comprises at least one pressure medium cylinder forheight adjustment of the follower roller. The one adapted to the hydraulic cylinderThe hydraulic control device is in this case preferably designed in such a way thatthe hydraulic cylinder can be stopped steplessly in desired positions along itssetting path, to enable a stepless height adjustment ofthe post-roll. Particularly advantageous is the previously mentioned master-slavethe arrangement of a pair of hydraulic cylinders.10152025306The invention is described in more detail below with the aid of apreferred embodiments and associated drawings. The drawings show:Fig. 1: a schematic side view of a soil cultivating device in the form ofa cultivator, according to an advantageous embodiment of the invention, whichcultivator is mounted on a tractor,Fig. 2: a schematic perspective view of the tillage device inFig. 1, which clarifies the arrangement of the hydraulic cylinder forworking depth adjustment of the cultivator pins via a height adjustment ofthe post-roll,Fig. 3: a schematic wiring diagram of the hydraulic steeringof the hydraulic cylinder for working depth adjustment of a head-slavedevice type, andFig. 4: a schematic side view of the tillage device in theprevious figures, which view shows the suspension of the height-adjustablethe follower unit via a parallelogram control.
    The tillage device 1 shown in the figures comprises amachine frame 2, which can be mounted on the rear trailer of a tractor 4 via amounting device 3, which may comprise a mounting bracket and an in andknown three-point linkage.
    As Fig. 2 shows, the said machine frame 2 can form a framework,which extends substantially horizontally across the direction of travel ofthe soil cultivating device 1.
    On the said machine frame 2 is a ground engaging tool unit 5attached in the embodiment shown, which grounding tool unit 5comprises three successive rows of cultivator sticks 6 whichextends transversely to the direction of travel in the embodiment shown, which rowsroughly extending vertically downward from the machine frame 2 and bearingcultivator tool 7 on its lower ground-facing ends, by means of whichcultivator tool 7 the soil is loosened, roots are cut off and the soilconditioned.
    A further roller 7 is further suspended on the machine frame 2, which inthe embodiment shown is designed as a cutting wheel roller and has a numberof adjacent cuts arranged along a common roll axis, cf.10152025307Fig. 2. The said return roller 7 is in this case arranged in the direction of travelafter said ground gripping tool unit 5, whereinthe post suspension 8, by means of which the post roller 7 is attached tomachine frame 2, extends rearwardly from the machine frame 2, compare Fig. 1.
    In the embodiment shown, the post suspension 8 comprises oneparallelogram link control 9, which comprises several link pairs, which are arrangedtransversely to the direction of travel spaced between the machine frame 2and the follower roller 7, compare Fig. 2. Each of said link pairshereby comprises two guide links 10 and 11, which are arranged at a distance fromeach other and are essentially parallel. The control links 10 and 11 are herepivotally coupled about a horizontal transverse axis at the rear end ofthe machine frame 2, so that they can perform up and down movements like rocker arms. Onthe ends facing away from the machine frame 2 are the said guide links 10 and 11likewise articulated around horizontal transverse axes with abacking unit carrier 12, which carries said backing roller 7.
    Coupling points 13 and 14 of the control links 10 and 11 onthe machine frame 2 as well as the connection points 15 and 16 of the mentionedthe control links 10 and 11 on the trailing unit carrier 12 hereby define inthe unfolded center position according to Fig. 1 the corner points of a rectangleand at the same time the link points of the parallelogram link guide 9,through which said said unit carrier 12 can be moved upwards anddownward substantially without rotation. Through the mentioned upward andthe downward movement of the guide links 10 and 11 and thus the trailing roller 11can a setting of the working depth of the extenderthe grounding tool unit 5 is achieved, sincethe soil cultivating device 1 essentially rests on the soil throughthe said backing roller 7. If the backing roller 7 is run furtherdownwards relative to the machine frame 2, the working depth of the preceding ones decreasescultivator sticks 6; if, however, the trailing roller 7 is driven upwards relativelymachine frame 2, increases the working depth of the cultivator pins 6.
    Between the said after-rolling roller 7 and the preceding onesthe cultivator pins 6 are further arranged an additionalground engagement tool unit 17 with others, from the cultivator pins 610152025308deviating ground grip tool. In the embodiment shown, the said comprisesfurther grounding tool unit 17 a row of car discs respectivelyhollow discs, which are arranged in a row extending transverselythe direction of travel and are rotatably suspended on disc shafts, which are roughly expressedextends horizontally across the direction of travel, but can be easily tippedtowards the horizontals and / or towards the transverse direction, that isthe direction exactly across the direction of travel.
    The said ground engaging tool unit 17 is herewithpreferably height-adjustable mounted or suspended together withthe post roller 7 relative to the machine frame 2. In particular canthe ground engagement tool unit 17 be suspended fromthe follower unit carrier 12, so that the ground engagement tool unit 17 followswith the height adjustment of the follower roller 7. At the same timethe ground engagement tool unit 17 on the other hand is preferably height-adjustableopposite the post-roll 7 and the post-unit carrier 12, respectivelycan be realized, for example, by means of a heel pattern and an associated removablebolt, so that a presetting of the working depth of the disc row 17 relative tothe follower roller 7 can be implemented.
    The working depth setting of the extending cultivator pins 6 takes placeconsequently by adjusting the height of the follower roller 7 and the one therewithconnected disc row 17. The associated working depth setting device18 here comprises a pressure fluid drive device 19, which has severalhydraulic cylinders 20 in the embodiment shown, which hydraulic cylinders 20are arranged parallel to each other and startparallelogram link guide 9, to set it to the machine frameThe said parallelogram link guide 9 consequently forms togetherwith the hydraulic cylinder 20 the height adjustment device 21 for height adjustmentof the post-roll 7 and thus on the other side at the same timethe working depth adjusting device 18 for adjusting the working depth ofcultivator sticks 6.
    As Fig. 2 shows, the hydraulic cylinder 20 is then hinged on one sideon the machine frame 2 and on the other side with its other end attached to one ofthe control links 10 of the link pair to the parallelogram link control 9.10152025309Preferably, in this case, the respective control link 10 is atthe parallelogram link guide 9 formed in the form of a lever, one of whichleg connects the rear unit carrier 12 to the machine frame 2 and whosesecond leg is connected to the hydraulic cylinder 20 in questionto achieve a compact device even with hydraulic cylinders with longeractuating path, the said hydraulic cylinders 20 are preferably roughly expressedarranged lying substantially in the direction of travel over the cultivator pins 6and / or over the machine frame 1, the hydraulic cylinders 20 extendingsubstantially perpendicular to the upwardly pointing leg of it as aangle lever designed guide links 10, to achieve favorablelever conditions.
    As Fig. 3 shows, the hydraulic cylinders 20 ofthe pressure drive device 19 is preferably connected to one another in onehead-slave device, to enable a stepless in a simpler waysetting and also enable movement to arbitrary intermediate positions.
    The master cylinder 20.1 is hereby connectable to a pressure source with its firstpressure chamber via a pressure source connection P, while the other chamber ofthe said master cylinder 20.1 is connected to the firstthe pressure chamber of the slave cylinder 20.2. The second pressure chamber of itsaid slave cylinder 20.2 is on the other hand connected via a returnand / or tank connection T. As Fig. 3 shows, the larger one canthe piston rod-free pressure chamber of the master cylinder be connected tothe pressure source connection, while the other, smaller and of the piston rodthe penetrating pressure chamber of the master cylinder 20.1 is connected tothe larger piston rod-free pressure chamber of the slave cylinder 20.2.
    The second pressure chamber of the slave cylinder 20.2, which is smaller and penetratedof the piston rod, is connected to the return connection, it being in cross sectionless the second pressure chamber of the master cylinder in cross section corresponds to itlarger pressure chamber of the slave cylinder, in order to achieve onesynchronized movement.
    The control device 23 for controlling the switching path and / or the stop position ofthe hydraulic cylinder 20 can in this case be designed in principle differently, for examplecomprise a controllable pressure source and / or pressure control means such as shut-off valves,101510flow control valves and the like. The control device 23 controls through suitablequantity control means the quantity of pressure medium flowing into the master cylinderand / or the amount of pressure medium flowing out of the slave cylinder respectivelyflows back, but the control device 23 may, however, also includepressure control means between the two hydraulic cylinders. The mentionedthe quantity control means is preferably electronically controllable, in order to be able to control itcorresponding inflow and / or outflow amount of pressure mediumexactly. It is possible instead of such an electrohydraulic design anywayalso possible with a purely mechanical / hydraulic design. The mentionedthe pressure medium control device 23 and / or its quantity control means can in this casebe arranged on the superstructure device itself, in order to be able to operatethe soil tillage device independently without regard to the saidcontrol possibilities of the tractor, and / or were arranged on the tractor.
