    description
    The invention relates to a device for supporting the
    and dismantling pasture fences.
    The basic functions known per se and optional advantageous additional functions known per se of a device for supporting the construction and dismantling of pasture fences are described with reference to the
    The exemplary device shown in WO 98/48135 A1 explains:
    The device according to WO 98/48135 Al is mounted on a vehicle. It includes one or more reels for flexible longitudinal material (fence tape or fence wire), one or more guide eyes for guiding the longitudinal material between reels and fence, a linkage consisting of mutually adjustable longitudinal parts, which the guide eye or the guide eyes
    carries, as well as a storage facility for carried
    Fence posts.
    A drive train that acts on a reel includes a drive motor and a slip clutch. When the drive motor is at a standstill, the reel can only be rotated while overcoming the torque limited by the slip clutch. When the drive is running, the reel is driven to wind up longitudinal material on its outer surface, the torque which the tensile
    force on the longitudinal material caused by the slip clutch
    is bordered.
    The absolutely necessary parts or functions of the device are a reel for winding and unwinding the longitudinal material, with the possibility of braking and a motorized drive for the reel, and a fastening device
    to be able to attach the device to a vehicle.
    For the construction of a pasture fence with the aid of the device according to WO 98/48135 Al, the drive of the reels is at a standstill. The starting ends of the longitudinal material are wiped off the reels.
    Ckelt, passed through the guide eyes and at a first in the
    Landscape anchored fence post attached. Then the vehicle on which the device is mounted travels along the line in the field on which the fence is to be set up. By moving away from the first fence post, the strands of the longitudinal material are unwound from the reels, the slipping clutch braking the rotary movement of the reels and thus ensuring good tension of the longitudinal material. At a distance from the last fence post in each case, another fence post is anchored in the terrain, typically rammed into the ground, and the flexible longitudinal material is fastened to it. In areas of the terrain where the vehicle cannot travel along the line on which the fence is to be placed - for example because a tree is in the way - the reels are removed from the device and carried manually along said line, then back onto the device attached and then driven by the reel drive so long that the unwound longitudinal area up to the slip limit of the slip clutches
    is excited.
    In the ideally simple case, when removing a pasture fence with the aid of the device, the ends of the strands of longitudinal material located there are only detached from the fence at one end of the pasture fence and are guided via the guide eyelets to the reels of the device, which is in turn mounted on a vehicle, and anchored there. Then the reel drive is started and the vehicle slowly drives along the existing fence. The reels wind up the strands of longitudinal material insofar as this is less tense due to the traveling along than is specified by the slip clutches in the drive trains of the reels. When the vehicle arrives at a fence post, the strands of the longitudinal material are manually removed from it and the fence post is pulled from the underground and into the storage facility.
    load on the vehicle.
    Deviations from the ideally simple case occur frequently, especially
    lem when the terrain has many obstacles, so
    2nd
    the vehicle that carries the device does not really move along
    of the pasture fence, or if a strand of the longitudinal material has become stuck in the landscape so that it cannot be pulled off easily, for example because it was overgrown by brushwood, or by grazing animals in marshy
    was kicked.
    In such cases, it is advisable to first walk along the fence, detach the longitudinal material from the pegs and, if necessary, from the undergrowth, etc., and carry the individual pegs to the next place to which the vehicle can drive well. The longitudinal material can then be wound up again with the aid of the device, whereby the device itself (and the vehicle on which it is mounted) is not moved in the field, but the reels are driven to wind up the longitudinal material, but this is often - According to the slipping clutch, the drive torque on the reels was too low to wind up the longitudinal material; often the speed of the hash
    perceived as annoyingly low.
    In order to avoid the latter problems, designing the slip clutches and the reel drive to be controllable leads to disruptively complicated operability and thus to the risk of incorrect use, and to higher acquisition costs and higher maintenance.
    need and higher susceptibility to damage.
    The object on which the invention is based is to improve a device of the type discussed for supporting the erection and dismantling of pasture fences in such a way that, while avoiding the problems mentioned in the previous paragraph, the winding movement of a reel, which causes the winding of longitudinal material, optionally also due to a greater drive torque and a higher speed than is possible for the normal operation of the device.
    times is.
    A reel shaft is proposed for solving the task
    to provide, which is arranged coaxially to the reel and rotatably connected to it against relative rotation about the common axis, and has a stub shaft, the end face and lateral surface of which are freely accessible. (A wave stump
    in this sense is a longitudinal end area of a shaft).
    This measure, which can be implemented without reducing robustness and largely without additional costs, ensures that the reel shaft at the freely accessible end area with the tool engagement part of a machine turning tool that is not part of the device, but is present in any agricultural operation anyway, such as, for example Hand drill or a cordless screwdriver, can be connected, and can be driven by the mechanical turning tool to rotate, whereby the reel - bypassing its standard drive - can be driven to rotate. Since this also bridges the slip clutch, the reel can be driven with significantly higher torque and at a significantly higher speed
    than would be possible with the standard drive.
    The invention is based on stylized drawings to an exemplary advantageous embodiment of an inventive
    Device illustrates:
    Fig. 1 shows an exemplary device according to the invention in side view. Fig. 2 shows the drive train of a reel of the device of
    1 in a detailed view compared to FIG.
    view.
    The device 1 according to the invention outlined in FIG. 1 has a base frame 2, wheels 3, holding parts 4, a drive housing 5,
    pelwellen 6, reels 7 for flexible longitudinal material 8, a linkage
    4th
    ge 9, guide eyes 10 and a storage device 11 for
    Fence posts 12 on.
    Due to the wheels 3, which are typically two fixed castors and two swivel castors, the device 1 can be driven on its own at least on a level, solid ground, such as in a barn. The holding parts 4 serve to anchor and lift the device 1 for the intended use on the hydraulically movable holding arms of a mobile agricultural machine, such as typically a tractor, in order to be able to move it through meadows and uneven terrain. The drive housing 5 carries the reel shafts 6 and houses the essential parts for their rotating drive. The reel shafts 6 carry the reels 7 and are connected to them in a rotationally fixed manner. The flexible longitudinal material 8 for the fence, ie fence wire or fence tape, is unwound from the reels 7 when a fence is built, and wound up when a fence is dismantled. The linkage 9 attached to the base frame 2 typically consists of steel hollow profiles attached to one another in adjustable plug connections; its function is to carry the guide eyes 10. The longitudinal material 8 is guided through the guide eyes 10 in the course between the reels 7 and the fence posts 12 anchored in the terrain. Typically, the guide eyes are 10 strong rigid wire bending parts that spiral into a kind of thread in a central longitudinal part.
    are shaped.
    In this case, the storage device 11 is designed as a plate with a grid perforation, the fence posts 12 being intended to be inserted into the holes of the grid perforation and thus being kept orderly. In a particularly preferred embodiment, the storage device 11 can be pivoted about its central axis in relation to the C basic frame 2 which supports it; so that the loading of the storage device 11 and the
    Can be removed particularly conveniently.
    The essential special feature of the device 1 according to the invention lies in the rotary drive of the reels 7. An exemplary inventive
    Execution for this is illustrated with reference to FIG. 2.
    The reel 7 is rotatably connected to a reel shaft 6 arranged coaxially to it, which is typically a round rod made of steel. The reel shaft 6 is passed through the drive housing 5, and held at the lead-through points through walls of the drive housing 5 by bearings 13 so as to be rotatable about its axis. In the longitudinal area lying in the interior of the drive housing 5, a slip clutch 14 is arranged on the reel shaft 6, the drive-side part 15 of which is rigidly connected to the reel shaft 6 and the drive-side part 16 of which is rigidly connected to a chain wheel 17. Torque is possibly transmitted through a friction lining 18 between the drive-side part 16 and the drive-side part 15 of the slip clutch 14. The sprocket 17 and thus the drive-side part 16 is possibly driven by a drive chain (not shown), which in turn is driven by a drive motor, typically an electric motor.
    Tor or a hydraulic motor is driven.
    If the device 1 - as outlined in FIG. 1 - has multiple reels 7, the individual chain wheels 17 of all reel shafts 6 can be driven together by one drive chain, which means that with a single drive motor for all reels 7
    Auslangen is found.
    The torque which can be transmitted from the sprocket 17 to the reel 7 is limited by the slip clutch 14, ideally to a degree at which the tensile force exerted by the reel 7 on the longitudinal material 8 is sufficient to set up and remove pasture fences To stretch longitudinal material 8 well, but not so large that there is a risk of malfunctions such as the tearing out of fence posts or even damage to parts. To expensive oversizing and excessive wear
    to avoid the friction lining 18 of the slip clutch 14, it is advisable

    sam, the drive motor for driving the sprocket 17 in terms of torque and speed should not be designed for higher values than those which are required for the function in the normal dismantling of
    Pasture fences are certainly sufficient.
    The construction of pasture fences with the aid of the device 1 is also possible comfortably when the reel 7 is not driven by a motor; it is sufficient if the chain wheel 17 is blocked against rotation and the reel 7 can only be rotated while overcoming the frictional torque of the slip clutch 14. In order to block rotation of the sprocket 17, the drive motor for the chain can be designed such that it locks itself as soon as it is switched off, or a separate, whatever type of locking device can be provided which blocks movement of the drive chain. For example, this can be a pawl which is pivotally mounted on the drive housing 5 and which engages with the drive chain or with a gearwheel which engages with it
    can be brought into or out of engagement.
    The end of the reel shaft 6 facing away from the reel 7 forms a stub shaft 19 which is freely accessible from the drive housing 5 on the side facing away from the reel 7
    protrudes.
    This provides a convenient possibility of being able to wind up longitudinal material 8 which is loose in the terrain or is still in a sales packaging, by the reel 7, by the drive torque for the required rotary movement of the reel 7 not via the chain wheel 17 onto the reel shaft 6 is applied, but by means of a mechanical turning tool that does not belong to the device 1, such as typically a cordless drill or cordless screwdriver, which is attached to the shaft
    blunt 19 attacks.
    In the present advantageous embodiment, the shaft is frustum

    forms so that it has an engagement geometry for the engagement of the
    offers mechanical turning tool.
    It is advantageous to provide the shaft end 19 for the engagement of the machine turning tool, which is not part of the device 1, not on the side of the reel 7 of the reel shaft 6, because this shaft end is due to the close proximity there.
    Chen longitudinal material 8 is not so accessible.
    For the advantageous feasibility of the construction according to the invention, it is important that if a plurality of reels 7 are used, they are not arranged on a common reel shaft, but rather on a separate reel shaft 6 in each case. Optimally, the reel shafts 6 are aligned parallel to one another and overlap in their longitudinal areas, because it becomes easy to connect them with a common drive chain or a common V-belt that runs in a longitudinal direction.
    tion of the reel shafts moving in the normal plane.
    The drive method described for FIG. 2 by means of a sprocket and drive chain is an exemplary advantageous drive mode because it is extremely robust and durable at reasonable costs and can be easily maintained and repaired with the means available in agricultural businesses if necessary. However, other types of drive can also be used within the inventive concept, for example pulleys and belts instead of sprockets and drive chains, as well as individual electrical or hydraulic
    motors for every single reel shaft.
