    Safety support for a header Description
    The invention relates to a safety support for a mounted on a feeder housing a harvester header, wherein the feeder housing is height adjustable by means of a feeder housing and the harvester hinged actuator relative to the harvester, with a pivotable at its first end support and a contact element to which the second End of the support with the actuator pulled out to relieve the actuator can be brought to bear.
    State of the art
    Before repair or maintenance work is carried out on harvesting attachments, which are attached to a harvester and adjustable in height relative to the harvester by means of an actuator, usually a hydraulic cylinder, measures must be taken to prevent unintentional lowering of the header intentionally.
    In addition to a hydraulic locking of the hydraulic cylinder by suitable valves, it is possible to mechanically lock the header. This locking is done in the prior art (DE 10 2004 042 126 A1, CN 202374720 U) usually by U-shaped elements which are pivotally mounted about the piston rod side articulation axis of the hydraulic cylinder on harvest header and for locking the header intentionally from above via the piston rod be pivoted after the hydraulic cylinder has been pulled out and the header is therefore in its highest position. The middle leg of the U-shaped element then lies on the piston rod and the ends of the element touch the end face of the hydraulic cylinder, after the latter has been slightly retracted again. A disadvantage is to be considered here that undesirable deformations and damage to the hydraulic cylinder can occur if the end faces of the element and the hydraulic cylinder are not aligned exactly exactly parallel.
    No. 3,981,126 A1 shows a combine harvester with an inclined conveyor which can be lifted by an actuator and can be locked in the raised position for maintenance by means of a support which is articulated on the inclined conveyor at a distance from the actuator and which is brought into contact with an axle housing of the combine harvester. US 2009/000158 A1 shows a wheel loader with a hydraulically liftable loader rocker, which can be locked by a support which is pivotable about the pivot point of the cylinder on the wheel loader and engages at a distance from the pivot point of the cylinder on the loader rocker. _
    task
    The problem underlying the invention is seen to provide an improved safety support for a header relative to the prior art. solution
    The present invention is defined by the claims.
    A safety support is proposed for a harvesting attachment attached to a feed housing of a harvesting machine, wherein the feed housing can be adjusted in height relative to the harvesting machine by means of an actuator articulated on the intake housing and on the harvesting machine. The safety support comprises a pivotable support and a contact element which is separate from the actuator and to which the second end of the support can be brought into abutment when the actuator is fully or almost fully extended in order to relieve the actuator.
    In other words, the support of the intake housing and thus of the harvesting attachment to the harvesting machine is independent of the actuator, by the actuator (completely or partially, but sufficiently far) is pulled out if necessary and then a support is pivoted at its first end. This support can then be brought with its second end in a (the spatially separated from the actuator) contact element adjacent position. If the actuator is then retracted slightly, it is relieved and only the support holds the feeder housing and the header. The actuator is therefore bridged by the support and the disadvantages of the prior art mentioned above are avoided. Thus, it is possible that the support does not directly touch the actuator and in particular its end face, whereby damage to the actuator is avoided.
    If the support and / or the contact element are fastened or hinged there, where the i
    Actuator is hinged to the collection housing and on the harvester, no measures for a structural reinforcement of the feeder housing and the harvester at the attachment points of the contact element and the strut are needed. However, it would also be conceivable to articulate the support at a distance from the articulation point of the actuator and / or to attach the abutment element from the articulation point of the actuator.
    In particular, the (in their inactive position spaced from the contact element) support is dimensioned such that it is not pivotable beyond its position adjacent to the contact element even with a fully extended actuator from the inactive position. This can be achieved, for example, in that the second end of the support is concave (in particular circular) arched or hook-shaped or straight and inclined relative to the horizontal or triangular or sawtooth or stepped or staircase-shaped, while cooperating with the second end of the support areas the abutment element are shaped complementary to the second end of the support. Thus, the advancing in the direction of adjustment of the second end of the support turn past the contact element until the trailing part of the second end of the support abuts against the contact element. There is thus no danger that the support will be inadvertently moved beyond the active position as required.
    The support is durable by holding means in the inactive position for the harvesting operation, in which the second end of the support is independent of the position of the actuator spaced from the contact element. Such holding means can be realized for example by a rope or a rod which can be releasably attached to the harvester or the feeder housing. The operator can then release the retaining means as needed to move the support (with the aid of gravity) e.g. down to their active, the header and the feeder housing supporting position. Similarly, the operator spends the support after completion of work on the header and / or feeder housing then manually upwards to its inactive position and locks it there by means of the holding means after the actuator has raised the feeder housing to relieve the support again sufficiently. The holding means may alternatively be designed as a leverage, connecting rod, actuator or the like. The actuation may be manual by means of a lever or remote controlled by means of e.g. hydraulic and / or pneumatic and / or electrical actuator. When the support is in its inactive position below the abutment member, the operator can manually raise the support to the active position, the support also actively upwardly biasing means, such as by means of a cable and one or more pulleys or a lever associated with the support weight or a spring supporting use could find. If the aforesaid post-up biasing means biased the post into the active position, the post would be locked in the inactive position by the retaining means and, upon release of the retaining means by the means, would be in the active position.
    Below or above the contact element, a guide surface is arranged, on which the support comes to rest, as long as the actuator is extended to a maximum extent to a predetermined extent and the support is not held by the retaining means in the inactive position.
    This achieves that the support after releasing the holding means initially rests against the guide surface and possibly slides on it when the actuator is pulled in or out. Only when the actuator is extended beyond the predetermined level, the second end of the support automatically enters the adjacent position of the contact element (or it is only when the actuator is extended over the predetermined amount, from the inactive position in the in the spent the investment element adjacent position). After the support in the the.
    Contact element adjacent position has arrived and the actuator is retracted again below the predetermined level, then supports the support the feeder housing and the header from the discharge of the actuator to the harvester. The guide surface can, for example, be flat, flat and inclined relative to the horizontal, in particular circularly curved, triangular, sawtooth or step-shaped.
    Preferably, the feed housing is pivotally mounted relative to the harvester about a horizontal and transversely to the forward direction of the harvester extending Einzugsgehäuseschwenkachse, the actuator hinged at its two articulation points to Einzugsgeh ^escheschenkachse parallel axes on the intake housing and on the harvester and the support at its first end articulated to Einzugsgehäuseschwenkachse parallel and to the pivot axis of the actuator coaxial axis.
    The support is hinged to the harvester and the contact element attached to the feeder housing.
    The proposed safety support can be used on any harvester, in particular a forage harvester or combine harvester.

    In the figure 1 is a self-propelled harvesting machine 10 in the manner of a self-propelled
    Forage harvester shown. The harvester 10 is built on a frame 12 supported by front driven wheels 14 and steerable rear wheels 16. The operation of the harvesting machine 10 is carried out by a driver's cab 18, from which a header 20 is visible. By means of the header 20 picked up from the ground Emtegut, z. As grass or the like, is fed to a chopper drum 22 via a feed conveyor 42 with Vorpresswalzen, which are arranged within a harvester 20 detachably supporting feed housing 50 on the front side of the forage harvester 10, which chops it into small pieces and gives it a conveyor 24 , The crop leaves the harvester 10 to a traveling trailer on a rotatable about an approximately vertical axis and adjustable in inclination discharge shaft 26. Between the chopper drum 22 and the conveyor 24 is a Nachzerkleinerungsvorrichtung 28 with two grain processor rollers, through which the material to be conveyed the conveyor 24 is supplied tangentially.
    The header 20 is designed as a so-called pick-up. The Emtevorsatz 20 is built on a frame 32 and is supported on both sides mounted support wheels 38, which are each secured via a support 46 on the frame 32, on the ground. The task of the header 20 is to scatter on the bottom of a field or pick up 49 stored crop in a swath and supply it to the harvester 10 for further processing. For this purpose, the header 20 is moved during the harvesting operation with a small distance to the ground over the field, while it is raised for transport on a road or on paths by means of an actuator 48 in the form of a hydraulic cylinder which the feeder housing 50 and the attached header 20 to the axis of rotation 58 of the cutterhead 22 is pivoted. The actuator 48 also serves to adjust the height of the Gutaufnehmers 20 above the ground, or for adjusting the contact pressure of the support wheels 38 on the ground. To harvest header 20 includes a cross auger 36, which promotes the recorded Good from the sides of the header 20 to a center, not shown discharge port, behind which the intake conveyor 42 follows. The harvesting attachment 20 also has a (as the transverse auger 36) rotatably driven Gutaufnehmer 54 which is disposed below the discharge conveyor 36 and lifts with its teeth 51, the material from the ground to pass it to the discharge conveyor 36. In addition, a hold-down 40 is attached to the frame 32 in the form of a sheet arranged above the crop receiver 34. In the following, directions, such as laterally, downwardly and upwardly, refer to the advancing direction V of the header 20 and the harvester 10, which extends to the left in the figures.
    Reference is now made to FIG. The actuator 48 is articulated to a first, rear pivot point 56 on the frame 12 of the harvester 10 and hinged to a second, front pivot point 60 on the feeder housing 50, in both cases to horizontal, transversely to the forward direction of rotation axes. At the first articulation point 56, the first end of a support 62 is also freely pivotably articulated about an axis coaxial with the axis of rotation of the actuator 48 at the first articulation point 56. The support 62 is held in its inactive position as shown in FIG. 2 by retaining means 64, which are a rope, a rod or the like. The holding means 64 are similar by an eyelet. fixed releasably to a holder on the feeder housing 50 or at another suitable location of the harvester 10, wherein it would also be conceivable to lead them into the cabin 18. Furthermore, a contact element 66 is attached to the second pivot point 60. The abutment element 66 is rigid, i. not rotatably fixed to the feeder housing 50, although a limited rotation of the contact element 66 would be quite conceivable. Above the abutment member 66 is an obliquely forwardly and upwardly extending guide surface 68 which, as mentioned above, does not necessarily have to be flat in itself. The abutment member 66 has a rearward, convex surface that mates with a concave surface at the second end 70 of the post 62. The support 62 and the abutment member 66 are, viewed from the top of the harvester 10, laterally adjacent to the actuator 48. In Figure 2, the feeder housing 50 and the header 20 are in a relation to the figure 1 raised position, since the actuator 48th is pulled out. This position can be used for transport or maintenance.
    The operation of the safety support according to the invention, which comprises the support 62 and the abutment element 66, is as follows. In the inactive position shown in Figs. 2 and 3, the support 62 is held in the inactive position by the retaining means 64, in which it is located relatively far above the abutment member 66, no matter how high the actuator 48, the feeder housing 50 and the Emtevorsatz 20 adjusted.
    Now, if the header 20 and the feeder housing 50 are to be locked in a raised position, e.g. Maintenance work, the operator can solve the holding means 64. Then, the support 62 lowers due to the force of gravity acting and reaches the position shown in FIG. 4, in which the intake housing 50 has not yet been raised to the maximum and the second end 70 bears against the guide surface 68. As the operator adjusts the actuator 48, the second end 70 slides along the guide surface 68, the relatively sharp shape of the lower portion of the second end 70 causing any contaminants to be removed from the guide surface 68 and abutment member 66. The guide surface 68 causes the support 66 in a possible failure of the holding means 64 or in an operator error, regardless of the direction of movement of the feeder housing 50 causes no damage to the surrounding components, as the support slidably defined slides on the guide surface.
    If the operator causes the actuator 48 to be pulled out beyond a predetermined amount, the support 62 reaches the position shown in FIG. 5, since the draw-in housing 50 is now so high that the second end 70 of the support 62 has left the guide surface 68 , slid with its lower portion at the top of the contact element 66 along and finally the second end 70 of the rear surface of the contact element 66 is adjacent. The upper region of the second end 70 of the support 62 rests on the upper region of the contact element 66 from above. In this case, initially still remains a small gap between the rear portion of the abutment member 66 and the concave portion of the second end 70, which is then closed when the actuator 48 is retracted again slightly (to the predetermined degree). Then the header 20 and the feeder housing 50 are supported on the support 62 and the maintenance or repair work can be carried out safely. It would also be conceivable that the operator first raises the intake housing 50 to the maximum and then lowers the support 62.
    Then, the support 62 does not slip on the guide surface 68 and the abutment element 66, but the support 62 turns immediately downwards until the upper region of the second end 70 of the support 62 contacts the upper region of the abutment element 66 from above the remaining gap between the rear portion of the abutment member 66 and the concave portion of the second end 70 can be closed by slight retraction of the actuator 48, as mentioned, to relieve the actuator 48.
    The removal of the support 62 then occurs in such a manner that the actuator 48 is pulled over the predetermined amount and then the support 62 is lifted by the operator and fixed in the inactive position by the retaining means 64. ,
    Figure 6 shows a possible, different shape of the second end 70, which is designed hook-shaped. The abutment member 66 is complementarily shaped rectangular.
    In the third embodiment according to FIG. 7, the support 62 is actively pulled into the locking position via a deflection element 74, which is preferably designed as a cable, via a deflection point, such as, for example, the first articulation point 56 (ie downwards through the pretensioning element 74) biased, for example by means of a spring 72). On the opposite side to the point of application of the biasing element 74 of the support 62, the holding means 64 are attached, by which the support 61 either automatically or remotely controlled (eg by a spring or an actuator in the form of a cylinder, etc.) or by hand by means of a tether, Connecting rods or similar in the inactive position (as shown in Figures 2 and 3) can be brought. In this third embodiment it is provided that the operator first brings the actuator 48 in the position of Figure 7, i. in a pulled-over the predetermined amount position, and then by means of the holding means 64, the support 62 is lowered into the position in which its second end 70 of the abutment member 66 immediately adjacent, wherein the biasing member 74, which could also be omitted, supporting acts and the Pull support 62 down. Finally, the actuator 48 is then retracted so that the support 62 carries the load of the header 20 and the feed housing 50 and the actuator 48 is relieved. The support 62 thus comes into contact with the guide surface 68 only when the holding means 64 fail or when the operator tries to bring the support 62 in a not foreseen position of the collection housing 50 in its locking position. The guide surface 68 thus prevents damage to other components of the feeder housing 50. The lifting of the support 62 against the force of the biasing member 74 takes place in reverse order.
    In another embodiment (not shown), one could provide the inactive position of the post 62 below the abutting member 66 so that the biasing member 74 biases the post 62 upwardly and the retaining means 64 hold the post in the inactive position during harvesting and release as needed so that it can be spent by the biasing member 74 up to the active position.
