    VARIETY
    This invention relates to a harvesting machine for harvesting root crops when the harvesting machine is moved in a direction of travel, comprising a frame and a harvesting unit attached to the frame:
    by means of a first connecting mechanism, with which the harvesting unit is pivotally arranged around a first pivot axis transverse to the direction of travel and transverse to a height direction;
    with the aid of a second connecting mechanism, with which the harvesting unit is movably suspended from the first pivot axis on the frame.
    Root crop harvesters are known in various embodiments, for example as structures pulled by, for example, a tractor or as supported structures or as so-called self-propellers. All kinds of root crops, such as potatoes, turnips, carrots, etc., can be harvested with this.
    Such harvesting machines comprise a transport device for driving the harvesting machine on a substrate with one or more wheels and / or one or more tracks. This transport device carries the said frame. A pick-up device is suspended from this frame. This receiving device can comprise one or more of said lifting units. Typically, harvesters include a pick-up device that forms one single harvesting unit. Such harvesting units comprise one or more harvesting units. These harvesting aggregates typically comprise a harvesting shears and a support element, such as, for example, a diabolo, or other means for harvesting the root crops. The one or more harvesting units can be pushed or pulled into the harvester.
    The pick-up device is typically hingedly mounted to a frame about a first hinge axis about a first hinge axis and to a frame using a said second hinge axis.
    B E2016 / 5976 distance from this first pivot axis suspended movably from this frame. However, it is also possible to attach the harvesting units to the frame separately with such a first connecting mechanism and such a second connecting mechanism.
    The first pivot axis allows the receiving device or its lifting units to be able to pivot so that the lifting shares can move up and down. Lifting or lowering the lifting unit is typically done using one or more actuators, which are typically hydraulic cylinders.
    A drawback in performing this hinge movement, however, is that the second connecting mechanism does not allow circular movement of the corresponding part of the lifting unit away from the hinge axis. Typically, this second connecting mechanism allows only a displacement of this part in a plane transverse to the direction of travel and also the height direction, so that the lifting shares are movable up and down according to this height direction. In order to be able to combine the hinge movement around the first hinge axis with the displacement movement which is possible with the aid of the second movement mechanism, the first hinge axis is always movably arranged in the harvester, this in the direction of travel. In the harvesting unit, however, a sieve belt is included which is tensioned more or less when the first pivot axis is displaced. Additional sieve web length must be provided for this displacement. The disadvantage of this extra sieve belt length is that the sieve belt in working position comes close to the bottom, so that the cleaning effect thereof is limited, or even drags against the bottom.
    The aim of the present invention is to ensure that this sieve belt in the harvesting unit does not have to come as close to the bottom.
    This object of the invention is achieved by providing a lifting machine for harvesting root crops when the lifting machine is moved in accordance with a direction of travel, comprising a frame and a lifting unit attached to the frame:
    B E2016 / 5976 by means of a first connecting mechanism, with which the harvesting unit is hinged around a first pivot axis transverse to the direction of travel and transverse to a height direction;
    by means of a second connecting mechanism, with which the harvesting unit is movably suspended from the frame away from the first hinge axis;
    characterized in that the second connecting mechanism comprises an upper pivot arm and comprises a lower pivot arm disposed below the upper pivot arm for connecting the harvesting unit to the frame, these pivot arms each hinged around respective first pivot points disposed towards the frame and around respective second hinge points that have risen towards the harvesting unit.
    Thanks to such an upper pivot arm and such a lower pivot arm, this second connecting mechanism now allows the lifting and lowering of the lifting unit to also move forward and rear, so that the movement of the part of the lifting unit at the height of this second connecting mechanism now circular motion happens. This circular movement can be closely connected to the hinge movement of this part of the lifting unit around the first hinge axis by a suitable positioning of these hinge arms. This means that the lifting unit at the height of the first hinge axis no longer has to move in the direction of travel, more or less, when lifting and lowering the lifting unit. By limiting the forward and reverse movement of the first hinge shaft, the necessary additional sieve belt length is also limited. This sieve belt therefore does not have to come as close to the bottom as with the prior art, so that its cleaning effect is optimized.
    The second connecting mechanism preferably further comprises a connecting pivot arm, wherein the upper pivot arm and the lower pivot arm are attached to this connecting pivot arm in the second pivot points and wherein this connecting pivot arm is pivotally attached to the lifting unit in a third pivot point. Using such
    B E2016 / 5976 connection s hinge arm it is easier to position the different Hinges in such a way that the corresponding part of the lifting unit gets the desired freedom of movement.
    Preferably, the said third hinge point is designed as a separate hinge point, wherein this third hinge point is preferably arranged below the second hinge point of the lower hinge arm.
    A said connection of the articulated arm is further preferably displaceable in the harvester in a plane according to the direction of travel and according to the height direction.
    In addition, such a connection hinge arm is preferably arranged substantially in the center of the harvesting unit, viewed transversely to the direction of travel and transversely to the height direction.
    The top hinge arm and the bottom hinge arm are preferably hinged to the frame in the first hinge points or attached to an intermediate connecting element, which is fixedly attached to the frame.
    The top pivot arm and the bottom pivot arm can each comprise one or more of said first pivot points and each may comprise one or more of said second pivot points.
    Preferably, these hinge arms comprise two first hinge points and one second hinge point. Alternatively, they may also include one first hinge point and two second hinge points. Less preferred, they can of course also comprise several first and / or second hinge points.
    The number of first and / or second pivot points of the top pivot arm and the bottom pivot arm is preferably chosen accordingly. However, this number can also differ between the top hinge arm and the bottom hinge arm.
    B E2016 / 5976
    When a pivot arm comprises several first pivot points, they are preferably arranged substantially symmetrically with respect to the center of the harvesting unit in a direction transverse to the rowing direction and transverse to the height direction. If a pivot arm comprises several second pivot points, these are also preferably disposed almost symmetrically with respect to the center of the lifting unit, this being viewed transversely to the rowing direction and transverse to the height direction.
    In a special embodiment, the top hinge arm and the bottom hinge arm are essentially fork-shaped.
    The top pivot arm and the bottom pivot arm are further preferably rotatable in each of their pivot points about a respective pivot axis extending transversely of the row and transversely of the height direction.
    In a particularly preferred embodiment of a harvesting machine according to the present invention, the harvesting unit is pivotally arranged around a second pivot axis according to the rowing direction by means of the second connecting mechanism.
    By arranging the harvester in a pivotable manner around a second pivot axis according to the driving direction (longitudinal direction of the harvester), using the second connecting mechanism, it can be ensured that, when the frame is kept flat, the inclination of the lifting unit in the slope of the field. sloping or sloping fields can continue to follow.
    This hinge arm can be made pivotally around a second hinge axis according to the direction of rotation of the second connecting mechanism in embodiments with said connection hinge arm, for instance by simply hinging this connection hinge arm in the third hinge point to the lifting unit by means of a ball joint.
    B E2016 / 5976
    Preferably, such a second pivot axis, viewed transversely to the direction of travel and transversely to the height direction, is raised almost in the center of the harvesting unit.
    By arranging the second pivot axis almost in the middle of the harvesting unit, this seen in the width direction of the harvester (transverse to the direction of travel and transverse to the height direction), the lifting unit will not, or only to a limited extent, be left or right at the height of this second connecting mechanism. can move.
    In existing second connection mechanisms, this second connection mechanism typically allowed lateral movement of the harvesting unit at the height of this second connection mechanism (width-wise movement). However, such a lateral movement has a negative influence on the operation of the harvesting unit. This lateral movement was limited as much as possible by means of additional hinges and arms in the connecting mechanism, but it was never avoided. When the lifting unit was lifted or lowered, the lifting unit in this prior art also made a displacement along the width direction of the lifting machine, so that the lifting units were no longer positioned centrally over the harvested crop. As a result, the digging machine had to be steered in the corresponding direction according to the width direction of the digging machine in order to put the digging units back in the desired position. These negative effects are now limited or resolved by limiting this lateral movement or preventing straps.
    An additional advantage of such a second connecting mechanism is that the view on the pick-up device is considerably less obstructed than in the prior art. When looking at the lifting units from a position in front of the pick-up device, this connecting mechanism considerably less obstructs the view behind the lifting units, which is the case, for example, with structures being pulled by a tractor or the like. When looking at the harvesting units from a position behind the pick-up device, this connection mechanism obstructs the view considerably less on the still to be harvested
    B E2016 / 5976 crop even before the pick-up device, which is the case, for example, with so-called self-propelled drivers.
    The present invention will now be explained in more detail with reference to the following detailed description of a harvesting machine according to this invention. The purpose of this description is only to provide illustrative examples and to indicate further advantages and details of the present invention, and thus cannot be construed as limiting the scope of the invention or the patent rights claimed in the claims.
    In this detailed description, reference is made to the accompanying drawings by reference numerals, in which Figure 1 is a perspective view of a frame and a lifting device of a harvester according to the present invention attached thereto by means of a first connecting mechanism and a second connecting mechanism;
    Figure 2 shows the second connecting mechanism of figure 1 separately in perspective;
    figure 3 shows the part of the harvester of figure 1 in front view;
    figure 4 shows the part of the harvester of figure 1 in side view.
    The figures show parts of a harvesting machine, which comprises a frame (1), which can be rolled using a wheel axle (19) with wheels (20). When harvesting, the harvester drives in the indicated driving direction (X).
    A pick-up device (2) is attached to the frame (1) by means of a first connecting mechanism (3) and a second connecting mechanism (4).
    The structure of the other parts (not shown) of the harvester and how they connect to the parts shown are known, so that this will not be discussed in more detail.
    B E2016 / 5976
    The illustrated pick-up device (2) is designed as a single lifting unit (2), which comprises two lifting units (17). Such a pick-up device (2) could also comprise several harvesting units (2), each comprising one or more harvesting aggregates (17). Each lifting unit shown (17) comprises a lifting share (15) and a diabolo (6). This could also be an alternative means of harvesting root crops, such as potatoes, turnips, carrots or similar crops.
    With the aid of the first connecting mechanism (3), the receiving device (2) is pivotable around a first pivot axis (R) according to the width direction of the harvester. With the help of this pivot shaft (R) the receiving device (2) can pivot so that the lifting units (17) can move up and down. The entire pick-up device (2) can be lifted or lowered for this purpose by means of the hydraulic cylinders (14), with which the pick-up device (2) is suspended on both sides of the frame (1). These hydraulic cylinders (14) are hinged to the frame (4). Alternatively, a single hydraulic cylinder, or several hydraulic cylinders, or other actuators could for instance also be provided for this purpose.
    With the aid of the second connecting mechanism (4), the pick-up device (2) is attached to the frame (1), so that the pick-up device (2) at this second connecting mechanism (4) can perform movements in a plane according to the height direction (H) and according to the direction of travel (X), but not transverse to these directions. To this end, this connecting mechanism comprises an upper pivot arm (5), a lower pivot arm (6) and a connection pivot arm (11).
    The top hinge arm (5) is fork-shaped and is hinged in two first hinge points (7) to a connecting element (13), which is fixedly attached to the frame (1). On the other side, the top pivot arm (5) is hinged to the connecting pivot arm (11) in a second pivot point (9).
    The lower pivot arm (6) is also fork-shaped and is fixed in two first hinge points (8) to the same connecting elements (13) as the
    B E2016 / 5976 upper articulation arm (6). On the other side, the lower pivot arm (6) is hinged to the joint pivot arm (11) in a second pivot point (10).
    The top pivot arm (5) is arranged completely above the bottom pivot shaft (6) in the illustrated embodiment. The top pivot arm (5) and the bottom pivot arm (6) are rotatable in each of their pivot points (7, 8, 9, 10) around a respective pivot axis (T1, T2, T3, T4) which transverse to the direction of travel ( X) and extends transversely to the height direction (H).
    The connecting pivot arm (11) is hinged to a take-up device (2) in a third pivot point (12), so that the take-up device (2) is pivotally disposed about a second pivot shaft (2) using the second connecting mechanism (4). S), which is substantially located in the direction of travel (X).
    The connecting pivot arm (11) is positioned practically in the center of the harvesting unit transversely to the direction of travel (X) and transversely to the height direction (H). This connecting pivot arm (11) is movable in a plane (A) according to the direction of travel (X) and also according to the height direction (H), which was indicated in figure 3. The complete second connecting mechanism (4) is arranged almost symmetrically with respect to this plane (A).
    With the aid of this second connecting mechanism (4), the receiving device (2) is movable at the height of this connecting mechanism (4) according to the said plane (A) and cannot make lateral movements transverse to this plane (A). The negative effects of such a lateral movement are thus avoided via this connecting mechanism (4).
    Thus, an up and down movement of the pick-up device (2) is possible along the height direction (H) and a forward and reverse movement according to the travel direction (X). Due to the geometry of the connecting mechanism (4), this movement is guided according to a circular movement, which is close to the hinge movement around the first hinge axis (R). Because of this, there is only one
    B E2016 / 5976 minimum forward and reverse movement (according to the direction of travel (X)) of the pick-up device (2) at the level of the first pivot axis (R) required when lifting or lowering the pick-up device (2). As a result, the sieve belt (18) in the receiving device (2) is only tensioned to a lesser or greater extent, so that no extra sieve belt length has to be provided. In working position this sieve belt (18) can hang further from the field because of this than in the prior art.
    An additional advantage of this second connecting mechanism (4) is that the view of the receiving device (2) is considerably less obstructed. When looking at the lifting units (9) from a position in front of the receiving device (6), this connecting mechanism (4) considerably hinders the view behind the lifting units (17).
