    Machine for obtaining hay
    The present invention relates to a machine for obtaining hay, in particular a circular swath layer, with at least one rake wheel which can be driven about a vertical rake wheel shaft, and a feeler wheel connected to the rake wheel, which wheel is suspended from a feeler wheel carrier connected to a machine frame and adjustable laterally with respect to the rake wheel set is bearing.
    In order to prevent the rakes from digging into the ground through soil arches in the case of circular swaths or rakes, it is known to connect a feeler wheel to the rake wheel which, viewed in the direction of travel, has a front sector of the rake wheel for this out runs resp. may be placed just behind the rake teeth. The documents DE 203 12 730 U1 or DE 699 06 178 T2 show, for example, circular swath supports with such a feeler wheel running out of the rake wheel, which can be arranged next to the support wheels arranged under the rake wheel.
    With such machines for obtaining hay, it has hitherto been desirable or even necessary to shift the feeler wheel sideways relative to the rake wheel, so that it is positioned in a different sector of the rake wheel circle. In particular, in the direction of travel for the rake wheel running out of the feeler wheel, it may be desirable that the feeler wheel further to the right resp. further to the left. This is desirable, for example, for circular swath trailers with more rake wheels, which can deflect sideways relative to the direction of travel and can work in different positions, for example to obtain a single swath or a double swath.
    In order to enable such a lateral adjustment of the position of the sensor wheel, it was proposed to suspend the sensor wheel carrier transversely of its longitudinal axis or to the side thereof, which is effected, for example, by a sliding guide of the sensor wheel carrier and / or by inserting the sensor wheel carrier into different positions with respect to the machine frame can be achieved. Such transverse adjustments of the feeler wheel carrier are however difficult, in particular if a part of the weight of the machine already rests on the feeler wheel, so that the feeler wheel carrier can clamp against the mold frame.
    Starting from this, the object of the present invention is to provide an improved hay-making machine of the aforementioned type, which avoids disadvantages of the prior art and advantageously further develops them. In particular, improved lateral adjustability of the feeler wheel, which allows a better adjustment of the feeler wheel position in different work situations.
    This object is solved according to the invention by a hay-making machine according to claim 1. Effective embodiments of the invention are the subject of the dependent claims.
    It is therefore proposed to replace the longitudinal slideability of the scanning wheel carrier arranged for a long time by a pivot possibility of the bag wheel carrier, so that the sensor wheel can be positioned in different sectors of the rake wheel wheel by pivoting the sensor wheel carrier. According to the invention, the feeler wheel carrier is pivotably suspended about a vertical pivot axis such that the feeler wheel can be positioned in different sectors of the rake wheel. Depending on the pivot position of the feeler wheel carrier, the feeler wheel scans the bottom in one sector of the rake wheel or in another sector of the rake wheel. Due to the pivotable suspension of the sensor wheel carrier, the lateral position of the sensor wheel can be easily adjusted, without this leading to a clamping of the sensor wheel carrier. Moreover, the conversion saves a large number of bolts, which simplifies handling.
    Advantageously, the pivot axis of the feeler wheel carrier is positioned such that when the feeler wheel carrier pivots, the feeler wheel moves over an at least approximately concentric arc-shaped path along the rake wheel circle. As a result, the feeler wheel remains approximately in the same proximity to the teeth of the rake wheel, i.e. the lateral adjustment of the position of the feeler wheel leads to no resp. only to a slight change in the distance between the feeler wheel and the path of the rake wheel teeth.
    In another development of the invention, the feeler wheel can advantageously be arranged outside the rake wheel circle covered by the rake wheel, while the pivot axis of the scanning wheel carrier is advantageously arranged within said rake wheel circle. In particular, the feeler wheel can be arranged in front of the rake wheel when viewed in the direction of travel, so that the rake teeth do not get stuck on the ground curvatures or similar unevennesses. can extend to the bottom. Said sensing wheel carrier advantageously extends substantially lying above the rake wheel. However, an arrangement of the feeler wheel carrier under the tine carrier arm of the rake wheel is also conceivable, in which case the feeler wheel, however, extends within the orbit traversed by the teeth of the rake wheel, whereby a certain delay occurs in scanning the bottom in the direction of travel.
    In an advantageous further development of the invention, the pivot axis of the trailing wheel carrier is positioned near the rake wheel shaft, so that pivoting of the trailing wheel carrier only involves a slight change in distance of the feeler wheel and the teeth, ie the feeler wheel adjusts itself on an approximately concentric circle path around the rake wheel. out. The pivot axis of the feeler wheel carrier does not have to be arranged precisely concentrically with respect to the rake wheel shaft. In a further development of the invention, however, the pivot axis of the feeler wheel carrier is positioned within the inner 50%, preferably in the region of the inner 25% of the radius of the rake wheel circle.
    Swiveling the feeler wheel carrier can in fact take place in various ways. A manual operation for pivotability may, for example, be provided. Alternatively or additionally, however, a pivotability supported by other energy can also be provided, which comprises an adjustment drive for pivoting the feeler wheel carrier.
    If a lateral adjustment of the feeler wheel is only to be carried out as a pre-adjustment and then to be maintained during the operation of the apparatus, in a further development of the invention, a lock of the feeler wheel carrier can be provided in a position once adjusted. A locking device operating with a form connection is advantageously arranged here, which prevents unwanted adjustment of the sensor wheel even under rough conditions. If desired, locking devices which also operate with a frictional connection and possibly also self-locking adjustment drives could be provided.
    However, in order to allow an adjustment of the feeler wheel position also during operation, a control device is provided in a further development of the invention for automatically controlling the pivotal movement of the feeler wheel support also while driving the machine for obtaining hay. The control device can in this case be semi-automatic for the purpose that a control signal predetermined by a driver or machine driver leads to a corresponding change in the feel wheel position.
    In a further development of the invention, however, the control device is automatically operable, depending on a machine parameter of the machine for obtaining hay and / or a tractor connected thereto, so that the position of the scanning wheel or roller. the pivot position of the sensor is automatically adapted to the changing machine parameter.
    In a further development of the invention, the angular position of the machine frame relative to the tractor and / or relative to the connecting device of the tractor can be taken into account. For example, if the machine frame is positioned in a certain pivotal position relative to a connecting frame of the machine for obtaining hay, the position of the feeler wheel for pivoting the feeler wheel carrier is adjusted accordingly and brought into another sector of the rake wheel.
    A particularly advantageous further development of the invention can be formed here in that the feeler wheel resp. the position thereof with respect to the rake wheel is automatically adjusted when making bends of the machine for obtaining hay resp. of the hay making machine and the tractor. The touch wheel is, so to speak, sent along. brought into another sector of the rake wheel when making turns, so as to enable optimum scanning of the soil even when going through turns. In a further development of the invention, the control device forms a control member for steering the sensor wheel carrier with a steering position of the tractor. The control device herein comprises on advantageous mode control means for controlling the pivot position of the feeler wheel carrier depending on a control position of the tractor and / or the adjusting trailing angle between the tractor and the machine for obtaining hay.
    Send this resp. steering the feeler wheel position can in fact be achieved in different ways. In a further development of the invention, the control device for this purpose can have an adjusting motor in the form of an adjusting cylinder for pivoting the sensor wheel carrier. Alternatively, a mechanical forced control, which preferably comprises a pivot rod system, may also be provided for correspondingly pivoting the wheel carrier when the trailing angle is changed, the forced movement being pivoted, for example, by pivoting the connecting stand relative to the machine frame of the machine for the machine. obtaining hay and thus a change in the trailing angle can be deduced.
    In addition to the said displaceability of the position of the feeler wheel in different angle sectors of the rake wheel, the feeler wheel carrier and / or the feeler wheel suspension can offer various other adjustment options. In a further development of the invention, the feeler wheel carrier can be changed in length, in particular telescopically, so that the distance between the feeler wheel and the circumferential circle of the teeth of the rake wheel can be changed. Alternatively or additionally, a height adjuster may be provided for adjusting the height of the feeler wheel, in order to vary with the parameters of the land to be worked, such as, for example, the softness of the soil and thus the danger of sinking into the soil, with different to drive the heights of the feeler wheel. The height adjustment of the feeler wheel can be realized in various ways in this respect. The feeler wheel can be height-adjustable, for example, relative to the feeler wheel carrier. Alternatively or additionally, the entire feeler wheel carrier can be adjusted in height with the feeler wheel mounted thereon.
    The feeler wheel itself is thereby steerable on the feeler wheel carrier, i.e. fixedly pivotable about a vertical axis, wherein a self-steering attachment can advantageously be provided in the form of a trailingly mounted feeler wheel.
    The invention is explained in more detail below with reference to a preferred exemplary embodiment and associated drawings. Show in the drawings:
    FIG. 1 is a schematic side view of a circular swathlegger connected to a tractor, the rake wheel of which is supported by support wheels under the rake wheel and by a feeler wheel leading in front of the rake wheel,
    FIG. 2 shows a perspective detail view of the feeler wheel and the feeler wheel suspension of the circle swath layer of Figure 1, and
    FIG. 3 is a top view of the feeler wheel and the feeler wheel suspension of FIG. 2.
    According to Fig. 1, a circular swathlegger 1 according to an advantageous embodiment of the invention comprises a machine frame 2, which can be built via a connecting piece 3 to a tractor 8, wherein according to Fig. 1 a rear connection is arranged on the tractor 8, in fact also a front connection. can be applied.
    In the embodiment shown, a rake wheel 4 is rotatably mounted on the machine frame 2 about a substantially vertical rake wheel shaft 5. The said rake wheel 4 herein has tooth carriers 6 arranged radially with respect to the rake wheel shaft 5, to the radially outer ends of which rake teeth 7 are fixed. The tooth carriers 6 are rotatably mounted in a manner known per se about their own longitudinal axis, wherein, for example, a rotational drive of the said toothed tooth carriers 6 takes place via a curve control surface and pivot levers, so that the tooth carriers are rotated cyclically about their longitudinal axis during rotation, in that the rake teeth 7 are directed downwards over a part of the orbit 8 to further rake hay from the soil, while the rake teeth 7 are pivoted upwards over another part of the orbit so that they leave the harvest material on the ground.
    Without this being shown in greater detail in the drawing, it is clear that a swath former may be attached to the rake wheel 4 in the form of a swath cloth.
    Under the rake wheel 4 a support wheel 9 is arranged, which rests within the bypass path described by the rake teeth 7 and the rake wheel 4 resp. the machine frame 2 supports on the ground.
    Outside the rake wheel circle, which is determined by the orbit of the rake teeth 7, a feeler wheel 10 is arranged which advantageously in the direction of travel for the rake wheel 4 and / or in an area in which the rake teeth 7 are directed downwards towards the ground , is applied.
    As Figures 2 and 3 show, the feeler wheel 10 is pivotally rotated about a vertical steering shaft 11 and, in particular, run-on to a feeler wheel carrier 12, which extends substantially lying above the rake wheel 4. Said feeler wheel carrier 12 is herein suspended in the area of the attachment of the rake wheel 4 to the machine frame 2, wherein the feeler wheel carrier 12 can be attached directly to the machine frame 2 or to a carrier connected thereto. The feeler wheel carrier 12 thus protrudes from the rake wheel 4 from the connection point located on the machine-adjusted side. The feeler wheel 10 is attached to the protruding end portion of the feeler wheel carrier 12.
    As those Figures 2 and 3 show, said feeler wheel carrier 12 is pivotably mounted at the end of the machine-controlled side about a vertical pivot axis 13, so that the feeler wheel 10 can be pivoted laterally relative to the rake wheel 4, i.e. transversely of the direction of travel can be moved to the right and left. The feeler wheel 10 allows the pivotability of the feeler wheel carrier 12 to be positioned in different angular sectors of the rake wheel 4.
    In the embodiment shown, the pivot axis 13 is positioned close to the rake wheel shaft 5, so that the feeler wheel 10, when adjusted laterally thereof, describes an arc-shaped path which rests against the bypass circle described by the rake teeth 7.
    In the embodiment shown, the feeler wheel carrier 12 can be pivoted by hand by means of a pivot locking device 14 which works with a form connection and can be fixed in different pivoting positions. In the embodiment shown, the pivot-locking device 14 comprises a spring-loaded engagement element, which is mounted on the feeler wheel carrier 12 and in one of more spaced-apart engagement cavities 15 of the machine frame 2 resp. of an attachment fixed thereto.
    In order to have the pivot position of the bag wheel carrier 12 automatically tracked. steering along with the steering position resp. the trailing angle of the machine frame 2 relative to the tractor 8 resp. the connecting piece 3, in a further development of the invention, however, a pivoting drive with a suitable control device can also be provided. For example, a hydraulic cylinder at a distance from the pivot axis 13 can be attached on the one hand to the feeler wheel carrier 12 and on the other hand to the machine frame 2 and be secured by a control device. which calculates the steering position of the tractor 8 or the trailing angle of the machine frame via suitable calculating devices.
    In a further development of the invention, said feeler wheel carrier 12 is of variable length, in particular telescopic design, see Fig. 2, wherein a suitable length-adjusting device can advantageously be provided, for example in the form of a spindle drive.
    Next, a height-adjusting device 16 is provided for adjusting the height of the feeler wheel 10. In the shown embodiment, the feeler wheel 10 is mounted in such a way that the height of the feeler wheel carrier 12 is adjustable.
