    FIELD OF THE INVENTION
    The present invention relates to a tool suspension for a vehicle, preferably a tractor, comprising a first frame for mounting the tool suspension and a second frame or connection for mounting a tool, the tool suspension comprising a pivot arm arrangement consisting of two arms rotatably mounted between the first and second frames, where the implement suspension has at least one outer position with the second frame in a position on the side of the vehicle's direction of travel, the implement suspension having a transport position with the second frame in a position opposite the direction of travel of the vehicle.
    By "direction of travel" in the present application is meant the direction in which the vehicle is moving or desired to move in such a way that the vehicle has a direction of travel, even if it is stationary. The direction of travel is an axis that coincides with a longitudinal vertical oriented median plane through the vehicle such that a parallel median plane through the second frame coincides with the median plane of the vehicle in the transport position and offset to the side of the vehicle median plane between the transport position and the outer position.
    BACKGROUND OF THE INVENTION
    When cultivating land, farmers want a specific nature of the land, where the upper part of the soil is worked through for approx. depth of five centimeters, while the soil layers below the worked soil layer must be firm. This has been shown to produce the best seedbed for the selected crops and then the greatest yield.
    The usual procedure for cultivating a field is as follows:
    (a) the earth is plowed to a depth of up to 25 centimeters;
    b) the soil is compressed with a soil compactor or drum;
    (c) the soil is seeded for sowing;
    (d) a selected crop was sown; and
    DK 2017 70891 A1
    e) compress the soil around the seeds with a soil packer or drum.
    The disadvantage of this process for cultivating a field is that the farmer must cross the field at least once for each of the aforementioned soil types, which is expensive and time consuming.
    As a solution to this, agricultural machine manufacturers produce combination machines, where two or more of the above-mentioned types of soil treatment are made during the same trip across the field.
    The ideal would be to be able to do all five types of soil treatment at once, but this would require a large and long combination machine and has not been possible so far.
    For example, a plow has been manufactured which is provided with a soil packer which is towed behind the plow. Thus a-b is combined in a workflow.
    Another example of a combination machine is a harrow / drill / drum machine, where the above-mentioned soil type c-e is carried out in one operation.
    Both examples are drawn after a vehicle, for example a tractor.
    The disadvantage of the first example is that the machine is difficult to maneuver in fields that are small or with corners, since it is only difficult to reverse with this type of combination machine.
    DK 177331 B1 describes a tool suspension for a tractor, where the tool suspension comprises a swing arm arrangement which uses two swing arms to hold the implement in position. The disadvantages of this construction are that the implement in the outer position can have a great distance from the vehicle, thus creating great forces and wear on the front lift system, and that many actuators are needed to move the implement.
    DK 177240 B1 discloses a tool suspension for a tractor which uses a slotted telescopic tube device to laterally move the implement close to the tractor to reduce wear and tear
    DK 2017 70891 A1 on the vehicle. A disadvantage of DK 177240 is that the implement is heavy and expensive to manufacture and that the telescopic device and actuators are susceptible to dirt and contamination in connection with the earthwork.
    The object of the invention
    It is an object of the invention to provide a tool suspension for mounting on a vehicle, where the implement suspension enables machining of a piece of land at each side of the vehicle or next to the vehicle and at the same time allows transporting a tool on the road in a position next to the vehicle.
    Description of the Invention
    This is achieved in accordance with the present invention with a vehicle suspension, preferably a tractor of the type mentioned initially, characterized in that the pivot arm arrangement comprises a first arm and a second arm in a plane substantially perpendicular to the direction of travel that it the first arm is pivotal about a first shaft connecting the first arm to the first frame, the second arm is pivotal about a second shaft connecting the first and second arm, and the second frame is pivotal about a third shaft, connecting the second frame to the other arm, and which axles are substantially parallel and parallel to the direction of travel.
    The implement will preferably be a front mounted implement suspension which is suspended via the first frame in a three point lift arrangement.
    Hereby it is achieved that a piece of ground can be machined on alternating right and left sides of the vehicle, so that the vehicle does not subsequently or respectively touch the ground piece. At the same time, it enables transport with a tool on the road, since the implement can be placed in a position close to and outside the vehicle.
    The tool suspension is suitable for tillage tools such as harrows, drums and knife drums. Furthermore, the tool suspension can be used with other implements, which include, for example, mowers.
    The invention reduces wear on the front suspension of the vehicle including the front wheel of the vehicle by keeping the implement close to the vehicle. At the same time, the invention is simple and inexpensive to manufacture, since only a single activating agent is required for operation.
    DK 2017 70891 A1
    According to a further embodiment, the tool suspension according to the invention is characterized in that it comprises only one first arm and only one second arm.
    According to a further embodiment, the implement suspension according to the invention is characterized in that the second frame comprises a fourth shaft which is substantially perpendicular to the direction of travel connecting a first and a second part of the second frame.
    This enables the implement to rotate and follow the direction of the vehicle's underground workings as the vehicle changes direction in the field and increases maneuverability during use.
    According to a further embodiment, the tool suspension according to the invention is characterized in that it is provided with a second locking arrangement which locks the tool for rotation about the third shaft, wherein the locking arrangement comprises a groove in the second frame and a plate part which is slidably mounted on the second arm. The plate part is in an initial locking position in engagement with the groove. In another unlocked position, the plate part is out of the groove.
    This results in the tool being locked for rotation about the third shaft during transport. Locking rotation about the third shaft is advantageous, as the implement does not rotate to the ground during transport and thus avoids any damage to the implement during transport.
    In a further embodiment, the tool suspension according to the invention is characterized in that the plate part of the locking arrangement has an end surface directed towards the first frame. Which end surface interacts with a contact surface on the first frame or first arm. The end face has a longer extension at a center section than at the transition to the side faces of the plate part. The locking mechanism is in a locked position when the implement is in the transport position with the first arm and the second arm perpendicular to the direction of travel, with the center section abutting against the contact surface. The locking mechanism is in the unlocked position when the implement swings out to one side or the other.
    This ensures that the implement is locked for rotation about the third axle during the transport position automatically without separate action by, for example, the driver of the vehicleDK 2017 70891 A1 jet. This avoids any damage to the implement during transport due to forgotten locking in the transport position.
    According to a further embodiment, the tool suspension according to the invention is characterized in that the plate part of the second locking arrangement comprises at least two plate parts connected to a compression spring.
    This results in the fact that the locking arrangement can be activated, even if the implement is rotated about the third shaft, so that the plate part cannot engage against the groove. The compression spring compresses during activation of the mechanism on the side of the first frame, and decompresses again when the implement is turned, so that the groove and plate part engage.
    According to a further embodiment, the tool suspension according to the invention is characterized in that the second locking arrangement comprises a plate part connecting the first and the second plate part, thus limiting the maximum length of the total locking arrangement in the direction between the first and second frame.
    This ensures that the second locking arrangement always complies with the maximum length required for safe operation. This is ensured irrespective of the forces the compression spring and any pulling spring exerts.
    According to a further embodiment, the tool suspension according to the invention is characterized in that the second locking arrangement comprises at least one pull spring connected to the plate part and the second frame. The tension spring acts so that the locking arrangement is in the unlocked position when the middle section of the end surface is not in contact with the abutment surface. The locking arrangement is in the locked position when the middle section of the end surface abuts against the abutment surface.
    This ensures that the locking mechanism automatically goes into the unlocked position when the first arm swings from the vertical transport position to a second position. Thus, the tool is ready for use without further manual interaction.
    According to a further embodiment, the tool suspension according to the invention is characterized in that the first and second arms are provided with interoperable stop stops,
    DK 2017 70891 A1 that defines the outer positions of the implement. The interlocking stop stops provide a weight transfer from the first arm to the implement.
    This results in the tool being stopped in an outer position and reducing wear on the locking mechanism and / or activating means.
    Furthermore, the stop stop provides a weight transfer from the first arm to the implement. This increases the weight pressure on the implement in the outer position.
    According to a further embodiment, the tool suspension according to the invention is characterized in that the first frame and the second arm comprise a cam groove and a cooperating cam, preferably a cam roller, which defines the swinging motion of the tool. The cam groove and the cooperating cam lock the implement to the side where the first arm is on when the first arm is not in the vertical position.
    The cam track acts as a locking mechanism for the implement to remain on the side the actuator is actuated when applying force to the implement during use.
    Furthermore, camshaft and camshaft define the pivotal movement so that the second arm, which is perpendicular to the direction of travel in the transport position, is turned out towards the side to which the actuator moves the first arm.
    According to a further embodiment, the tool suspension according to the invention is characterized in that the second arm comprises two arm parts arranged perpendicular to one another, at one end distant from the other shaft, an arm part is provided such that the second arm is L-shaped. .
    This provides a simple and effective embodiment of the described locking mechanism in the transport position.
    According to a further embodiment, the tool suspension according to the invention is characterized in that it comprises only one activating means, preferably a linear double acting hydraulic actuator.
    DK 2017 70891 A1
    The fact that the tool can be made with a single activator significantly reduces the cost of manufacture and complexity. Furthermore, it simplifies and reduces the cost of maintenance of the tool suspension. The linear double acting hydraulic actuator may be disposed at an angle of approx. 15-25 degrees, preferably 18-20 degrees, between the direction being actuated and the first arm in a vertical position. This optimizes the distance the implement can have from the tractor in the outer position. At the same time, cam and cam tracks provide the desired movement of the implement.
