    Device for agricultural machinery which comprises a unit with both a tool working in the ground or a holder or bracket for this, as well as a roller wheel in the working path of the tool. The unit of tools and wheels is pivotally or pivotally mounted in a suspension device about an axis which is perpendicular to the direction of movement of the tool, and that there is no one or more stops for limiting the pivotal movement of the unit relative to the suspension device by locked, unlocked or limited adjustment of the turning movement in one and / or the other direction.

    1015202530There is a sprint 10 that can be inserted into different holes 11 - 14 in the ring. The square beam 8 which iscommon to a number of tool suspensions is via a number of ears 15 with pivot bearings 16stored for rotational movement in the machine so that by swinging the beam by one or fl erahydraulic cylinders assume this different rotational positions as well as those attached to the same square beamthe devices.
    The invented tool holder allows new functions, which increases the usefulness of the machineare mounted because it allows different ways of working with the beetles.
    The divided and articulated holder 1, 5, 6 can be set in five different main working positions byyou place the pin in different holes. The five main functions are described below. Stop canalso consist of steplessly adjustable stops.
    The tool is positioned by means of the rotation of the beam 8 which changes the angle ofparallel arms and thus the tool holder angling and or the function of the tool holderdepending on the location of the sprint (in the example a sprint, can also consist of Adjustable stops).
    The rotary movement cooperates with the steering wheel to steer depending on the location of the pinthe position and or function of the beetle. The pressure on the beetle is mainly controlled by the height of the frame sothat a greater or lesser part of the weight of the machine from its wheels is taken over by toolsor sawbill and the machining depth steering wheel. Both pressure and depth can thuscontrolled from the tractor.
    Locked position (fig. 1 and 2): The pin is inserted in the hole ll and through an underlying hole inthe extension 5.
    The rotation of the beam 8 changes the depth geometrically. The angle of the beam 8 determines viathe parallelogram the slope of the arm 1, which in turn determines the level between the wheelrespectively the lower edges of the tool and when the wheel (steering wheel) rolls on the ground (bill irelation to wheels and ground). The depression of the tool towards and into the groundstopped by the wheel so that a substantially constant sowing depth is obtained. The required pressuredownward on the tool is adjusted with the height of the frame.
    The rotation of the beam 8 changes the depth geometrically. The angle of the beam 8 determines viathe parallelograms and the connection locked in this position between ann 6 and arm 11015202530the inclination of the arm 1. Since the steering wheel rests on the ground, the movement pattern changesthe beetle 2 so that the beetle moves substantially upwards or downwards when the beam 8 is rotated.
    Fig. 1 shows the position of the parallelogram with wheels and tools at the same level on the ground andIn fi g 2, the inclination of the arm 1 in the beam 8 has been increased so that the tool 2 extends a distancedown into the ground while the depth control wheel 3 rests against the ground.
    Fully movable position fig. 3 and 4 (no sprint at all)The rotation of the beam changes the pressure of the beetle downwards so that it can follow a seedbed, Fig. 3low depressing pressure, fi g 4 high pressure down Pressure can also be adjusted with the height of the frame.
    The wheel 3 abutting against the ground can be replaced by a pressure wheel which is narrow and fallsdown into the groove provided by the seed beetle 2 so that the soil around the seeds is pressed to.
    Movable downwards, locked upwards fig 5, 6 (sprint in front position hole 12)The rotation of the beam 8 limits the movement of the beetle to a min depth, ie. the bill can followthe seedbed downwards but is locked to not be able to go shallower than the setting correspondingthe abutment of the extension against the sprint. Pressure is adjusted with the height of the frame. Fig. 5 the upperthe limit position with the current rotation of the frame 8 and fi g. 6 a deeper positionMoving upwards, locked downwards fi g. 7 and 8 (sprint in rear position, hole 13)The rotation of the frame limits the beetle to a maximum dj up, ie. bill canfollow the seedbed upwards but is locked to not be able to go deeper than the setting, ie whatthe sprint allows before the wheel prevents foot lowering. Fig. 7 a high position for the beetle andfi g. 8 the lowest position with the current rotation of the frame 8. Pressure is adjusted with the frameheightMovable up and down but limited mobility (sprints on both sides with games orex. inmiddle with an elongated hole 14. g. 9, 10). The rotation of the beam 8 sets a position where the beetlegets a moving area ie. both a min and max depth and the area in between. Printadjusted with the height of the frame. Fig. 9 highest position of the beetle with the current rotation of the frame 8and fi g. 10 lowest position10152025It is possible to have holes that give a clearance a lot up or down depending onif you want they fi nier an area where the beetle can be mobile but still have both a mine andmax position.
    Advantageously, the pins can be replaced with Adjustable stops that make all settings completelystepless.
    The device allows different types of cars to be used and different strategies to be useddepending on the conditions of the moment. Today's machines are built for different strategies andhas different pros and cons. The farmer chooses your layout and type of preparation depending onwhat type of seed drill he uses. It is common for the machines to be equipped withdisc beetles and the depth is limited by the wheel by locking the relationship betweenbill and wheels. This is usually a good method that reduces dependence on ear work. It canhowever, in some situations it may be good to be able to follow a seed boat e.g. when a poor structure in the soilcauses dry soil to lie above an uneven seedbed that is partly deep down. In these situations cana trailer beetle is preferable in combination with the place being set in a movable position, which means thatthe beetle is pressed with capercaillie force (electric hydraulic cylinder, etc.) against the seedbed and follows it. Thecan also be good to be able to limit that the beetle can not go too shallow or too deepbecause too shallow sowing can give too dry environment for the seeds or that they freeze up while onetoo deep sowing can mean that the plant does not have the strength all the way up, deep sowing can also meanpoorer stocking.
    The device can be further modified so that the split holder can be turned to getoption to have the wheel behind or in front of a tool or bill. This can, for exampleprovided with a pull-out shaft pin in the bearing between the arm 1 and the extension 5.
