    Harvest header with side cover
    description
    The invention relates to a header, the at least one hinged at the middle part, by an actuator between a horizontal working position and a raised transport position movable side panel, attached to the middle part and the side panel elements for receiving and promoting plants and a power-operated on the outside of the in the transport position located side panels attachable cover for side cover of the side part in a road trip includes.
    State of the art
    Harvesting attachments for harvesting and harvesting crops are used on self-propelled harvesting machines. Due to recent increases in performance of harvesters, ever wider crop headers are being used which have a relatively large mass. While combine harvesters are usually rigid in themselves and are separated from the combine for road transport and stored on a trolley, corn pickers for combine harvester and corn forage for forage harvesters are usually made hinged. However, there are also hinged cutting units for combine harvesters. For road transport outer side panels of harvesting headers are pivoted into a transport position, usually upwards or inwards. The folding harvesters remain attached to the front of the harvester during road transport.
    When driving on a road, it makes sense to cover the sides of the header in order to reduce the risk of accidents emanating from the sharp-edged plant conveyor elements of the header. Such covers are usually mounted by hand by the driver of the harvester, which is quite time consuming as the driver must leave his workstation.
    DE 10 2004 059 052 A proposes to equip a chassis serving to support the header in a road trip with a side cover for the header. This solution requires an additional chassis that is not available on all harvesters and headers.
    Another side cover of a header is proposed in EP 2 020 172 A1, which is considered to be generic. There is hinged at the central part of the header a lateral cover which is pivoted by a mechanical coupling about the vertical axis to the front, when the side parts are pivoted by 90 ° upwards, and then cover the side parts for road transport to the side. These covers consist of a tube construction, are embedded in the plates and thus have considerable masses, which are always carried.
    task
    The object underlying the invention is seen in providing a harvesting attachment with side parts which can be brought into a transport position and a lateral cover for the transport run, which can be attached in a simple manner and which is relatively easy to build. solution
    The present invention is defined by the claims.
    A harvesting header has a central part, at least one hinged at the middle part, by an actuator between a horizontal working position and a raised transport position movable side panel, attached to the middle part and the side panel elements for receiving and promoting plants as well as a power-operated located on the outer sides of the transport position Side panels attachable cover for side cover of the side part in a road trip on. The cover comprises a flexible material in itself (or consists thereof), which is wound in befindlichem in the working position side part on a side part supported on the reel and is located in the transport position befindlichem side part by at least one power-operated arm in a laterally covering the side part position ,
    In other words, the lateral cover of the side part of the header in the raised transport position by a kind of roller blind, i. a flexible material which can be unwound by a power-operated arm from a reel, as a rule against spring force. This cover is characterized by a low mass and a small space requirement, especially in the retracted position during operation. The cover is attached without the driver having to leave his workplace on the harvester.
    Preferably, the reel is attached to the back of a support frame of the side part. On the one hand, it does not interfere with the harvesting operation and on the other hand it is also relatively protected against crop influences and damage when driving on bumps in the ground.
    The flexible material of the cover may be fastened with its outer (in the transport position front) end to a holding plate connected to the arm, which extends in the working position and in the transport position parallel to the forward direction. This holding plate serves on the one hand to a smooth transfer of the movement of the arm on the flexible material of the cover and on the other hand to shield the reel down in the working position.
    Although it would be conceivable to linearly shift the arm and thus the cover to move it between the retracted working position on the reel and an extended transport position in which it covers the side part to the side, it is preferable to the arm force-actuated by a Rotate axis of rotation. The axis of rotation of the arm is preferably in the direction of extension of the side part in the forward direction approximately in the middle of the side part and extends parallel to the longitudinal axis of the reel and a support frame of the side part.
    The power-operated arm could be moved by an associated, separate actuator. For the sake of simplicity, however, it is advisable to mechanically couple the arm with that actuator, which moves the side part between the working and the transport position. This coupling of the arm with the actuator can be done by a rope which is coupled with a first end to the central part and a second end to the arm, so that the arm unwinds the cover of the reel and in the laterally covering the side parts spends when the actuator spends the side panel in the transport position. The rope can lie on a disc connected to the arm and the rope can be unwound from the disc when the actuator spends the side part in the transport position, and it can be guided around a deflection roller. However, other possibilities would be conceivable, such as a coupling by rods and / or gears, to couple the movement of the actuator of the side part with the arm.
    There may be two arms at both lateral ends of the side member and the cover may be disposed between the arms.

    FIG. 1 shows a self-propelled harvesting machine 10, such as a self-propelled forage harvester. 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 crop, z. As corn plants or the like, via a feed conveyor 42 with Vorpresswalzen, which are arranged within a harvestable header 20, by a cylinder 48 height adjustable feed housing 50 on the front of the forage harvester 10, a chopper drum 22 fed, which chops it into small pieces and it gives up a conveyor 24. The estate leaves the
    Harvesting machine 10 to a moving 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 of the conveyor 24 tangentially is supplied.
    Although the invention is shown here on a forage harvester, it can also be used on combines with associated harvesting attachments, such as cutters or corn pickers. In the following direction, as before, behind, laterally and above refer to the forward direction of the harvester 10 and the header 20, which extends in the figure 1 to the left.
    To pick up the crop, the harvesting attachment 20, which is fastened in the forward direction on the front side of the harvester 10 is used. The header 20 in the illustrated embodiment is a per se known corn mower attachment comprising a center portion 30 and two (with respect to the forward direction of the harvester 10) laterally to the left and right of the center portion 30 disposed side portions 32. The middle part 30 comprises a support frame 34 supporting it and the side parts 32 comprise supporting support frames 36. The support frames 36 of the side parts 32 are upwardly extended by actuators 40 in the form of hydraulic cylinders (see Figure 2) about horizontal and forwardly extending axes 60 pivotally mounted in a transport position on the support frame 34 of the central portion 30, as shown in Figure 1, and can be hydraulically swung down for harvesting use, so that they run in their working position during harvesting parallel to the support frame 34 of the central part 30, as shown in Figure 2 , On the support frame 34 of the central portion 30, four elements 44 are mounted in the present embodiment for receiving and conveying plants in the form of collection and mowing drums with lower cutting discs and above conveyor discs with distributed around their circumference recesses for receiving plants, while on both support frame 36 of the side members 32 are each mounted two elements 44 for receiving and promoting plants. The harvesting attachment 20 is equipped in a conventional manner with Halmteilern 52, the elements 44 for receiving and promoting plants, divisional tips 46, cover plates and lateral and Abgabefördermitteln to supply the harvested Good the chopper drum 22 of the harvester 10. In operation, the harvesting header 20 pulls up the stalks of the crop in an upright position, cuts them off and feeds them to the intake housing 50 and then to the chopper drum 22 of the harvesting machine 10. It could be outside on the
    Side parts 32 still further side parts (not shown) are attached, which are pivoted in the transport position to the inside or below.
    The support frame of the header 20 further comprises an upper cross member 54. The support frames 34, 36 of the middle part 30 and the side parts 32 extend down the rear of the header 20. On the front side of the support frame 34 of the middle part 30 are screwed gear housing 56, the Drive each have an element 44 for receiving and promoting plants. A drive shaft 58 for driving the elements 44 for receiving and conveying plants via arranged in the gear housings 56 gear, which also serves to drive the transverse and output conveyor of the header 20 and is driven by an output shaft of the harvester 10 extends in the lateral direction within the hollow support frame 34 of the middle part 30 and within the support frame 36 of the side parts 32nd
    The upper cross member 54 extends laterally above the inlet of the feeder housing 50 across its width. It is connected to hook-shaped support elements which are partially underlapped by complementary support elements of the feeder housing 50 and serve to attach the header 20 to the harvester 10. It is connected to the support frame 34 of the central part 30 by means of vertically extending supports and connecting plates. Between the upper cross member 54 and the vertically extending supports and connecting plates (and thus the support frame 34, 36 of the middle part 30 and the side parts 32) may be a per se known pendulum bearing, which provides a pivoting movement of the central part 30 and the side parts 32 to a allows horizontally and forwardly extending virtual axis, which is located approximately in the center of the feed housing 50.
    The side parts 32 are covered to the side in the transport position (see FIG. For this purpose, a cover 62 of intrinsically flexible material, e.g. Fabric or plastic, provided. The cover 62 is wound in the working position on a reel 64 and is unwound in the transport position thereof. At the front end of the cover 62, a holding plate 66 is arranged.
    Reference is now made to Figures 3 to 5, in which the attachment and function of the cover 62 and the mechanism are shown in more detail for their adjustment. The reel 64 with the cover 62 wound thereon in the working position is at the back of the
    Support frame 36 of the side part 32 on the support frame 36 by end-side brackets 68 (see Figure 2) attached. The reel 64 is a tube which is in particular prestressed by a torsion or spiral spring and which is mounted rotatably about its longitudinal axis on the holders and on which the material of the cover 62 is wound, as in the case of a projection screen or a roller blind.
    The outer end of the cover 62 is fixedly connected to the retaining plate 66, which extends in the working position shown in Figure 3 horizontally below the support frame 36 of the side part 32 to the rear to below the reel 64 and slightly forward over the support frame 36 also. At the rear end of the retaining plate 66 is angled upright at right angles. The retaining plate 66 extends over the entire width of the cover 62 and the reel 64. The cover 62 is connected to the retaining plate 66 by a plurality of screws 70 distributed over their width. A support tube 72 is located between the reel 64 and the retaining plate 66th
    The retaining plate 66 is attached at both ends to an arm 72 which is rotatably mounted on a gear housing 58 or a divider 46 about a rotation axis 74 which is in the forward direction of the header 20 approximately in the center and parallel to the longitudinal axis of the support frame 36 of the side part 32 and the reel 64 extends. The region of the arms 72 adjacent to the axis of rotation 74 is designed as a semicircular disk 76 which has a peripheral groove in which a cable 78 is accommodated. The first end of the rope 78 is connected to the middle part 30, e.g. whose support frame 34, fixedly connected and is guided from there to a guide roller 36 fixed to the guide pulley 80, whose axis of rotation extends approximately vertically. From the pulley 80, the cable then extends to the disc 76 and is fastened with its second end to the front end of the disc 76.
    Figures 6 and 7 show the guidance of the cable 78 at the interface between the support frames 34, 36 of the middle part 30 and the side part 32. A support arm 92 fixed to the support frame 36 is above the support frames 34, 36 through the axis 60 with a support arm 94 the support frame 34 pivotally connected. The cable 78 abuts from below to a side pulley 88, which is attached to the support frame 36, and to a central diverting pulley 90, which is attached to the support frame 34. The first end of the rope 78 is fixed to the support frame 34. Based on the working position shown in Figure 6 and the transport position shown in Figure 7 can be seen that the cable 78 is subtracted from the support frame 36 of the side part when the support frame 36 is pivoted by 90 ° upwards.
    A downwardly curved skid 86 is located below the gear housing 58. Below the gear housing 58 (or at the rear of the skid 86) is still a rearwardly and downwardly extending deflector plate 82 attached to which (in the working position) to the rear Holding plate 66 connects. The skid 86 and the deflector 82 extend in the lateral direction only below the gear housing 58. The skid 86 and the deflector 82 could also be made in one piece.
    The function of the mechanism for adjusting the cover 62 can be clearly seen from FIGS. 3 to 5. When the actuator 40 lifts the support frame 36 of the side member 32, the guide roller 80 moves with the support frame 36 opposite the support frame 34 of the central part 30, so that the distance between the first end of the cable 78 and the guide roller 80 changes, as shown in the figures 6 and 7 is shown. The cable 78 thus pulls against the disc 76 and causes it to rotate about the axis 74. As a result, the arm moves about the axis 74 and pulls out the holding plate 66 with the cover 62 to the outside, as shown in Figure 4. In the end position of Figure 5, which corresponds to the transport position, the arm 72 is rotated by 180 ° and extends from the axis 74 forward. The cover 62 abuts against the runner 86 and the support tube 84, which prevent the cover 62 on the deflector plate 82 or other sharp-edged areas of the Emtevorsatzes 20 scrubs. The cover 62 thus covers the header 20 to the side. The return movement to the working position takes place in the reverse manner, wherein the spring of the reel 64 pulls the cover 62 onto the reel 64 and winds it up and the cover 62 rotates the arm 72 about the axis 74 back into the position of FIG. The retaining plate 66 serves in the transport position as a protection device for the front divider tips 46 and in the working position for the support frame 36 as a wear skid.
    If a cover of the Emtevorsatzes 20 also be desired forward, it can be manually or in the manner attached, as shown in Figures 1 and 2 of the applicant's application with the internal file number P23276. Alternatively, a front cover may be attached to a chassis or a protective device mountable only for road travel on the header, cf. DE 10 2014 209 203 A1. Furthermore, front side lighting devices could be attached to the retaining plate 66.
