    Ejection arrangement for attachment to the end of a discharge device
    description
    The invention relates to an ejection arrangement for attachment to the end of a discharge device for material, the discharge direction of which can be changed by a guide element of the ejection arrangement which deflects the material and can be adjusted in position by an actuator, and an agricultural machine equipped therewith, e.g. Forage harvester.
    State of the art
    Forage harvesters are harvesting machines that pick up crop material from the ground, chop it and convey it by means of a post-accelerator through a discharge device, from which it is released onto a storage area of a transport vehicle traveling alongside or pulled by the forage harvester. In order to be able to fill the transport vehicle in a controlled manner, the direction of ejection can be changed by rotating the discharge device about a vertical axis. The height of the outlet-side end of the discharge device can also be adjusted in some embodiments in that the discharge device can be pivoted about a horizontal axis. In addition, an adjustable discharge flap is provided at the outlet end of the discharge device for specifying the discharge direction.
    Similar discharge devices, in which any material is transported by a conveyor and at the end of which the discharge direction is specified by an ejection flap, which deflects the material more or less in a direction determined by the plane of the ejection flap, can also be found, for example, in snow blowers and feed distributors and combine harvesters (see US 5,167,581 A).
    BE2019 / 0004
    Previous ejection flaps usually comprise two (DE 33 16 325 Al, EP 1 344 446 Al) or three (WO 2012/022564 Al) arranged one after the other, rigid, flat elements that are adjusted by a mechanism such that they at least approximately lie in an arc. Nevertheless, more or less large angles remain between the inherently flat and inflexible elements, especially with small radii of the circular arc, which hinder the flow of crop.
    EP 3 153 001 A1 describes a combine harvester with a door arranged between a straw chopper and a spreading device for the straw, which can be adjusted between a raised swath depositing position and a lowered spreading position and consists of a rear, rigid part and a front, flexible part There is part that deforms when the rear part of the door is adjusted to enable a smooth transition of the chopped material. Use as an ejection flap is not intended.
    SU 1 428 262 A1 shows a harvesting machine for silage material with a discharge chute, at the end of which a guide device made of a flexible material is arranged, which can be moved by means of a hydraulic cylinder along slots arranged on both lateral ends to determine the direction of curvature and ejection Change control device. The movement of the guide device within the slot is susceptible to canting and crops accumulating in the slot.
    The post-published EP 3 300 582 A1 shows a forage harvester with an ejection elbow, at the end of which a flexible, bellows-shaped wall with an intrinsically rigid ejection end is attached, which can be adjusted by rotating motors in both directions transverse to the crop flow direction.
    BE2019 / 0004
    The likewise subsequently published EP 3 298 875 A1 shows a combine harvester with a guide element attached to the end of the unloading pipe, the upper side of which can be deformed by an actuator which acts on the guide element via a rotating eccentric.
    task
    The problem underlying the invention is seen in providing an improved ejection arrangement for attachment to the end of a discharge device and a forage harvester equipped with it, in which the disadvantages mentioned do not occur or occur to a lesser extent.
    solution
    According to the invention, this problem is solved by the teaching of patent claims 1 and 10, features being listed in the further patent claims which further develop the solution in an advantageous manner.
    A discharge arrangement for attachment to the end of a discharge device, the discharge direction of which can be changed by a guide element of the discharge arrangement which deflects the material and whose position can be adjusted by an actuator, is characterized in that the actuator is coupled to an adjustment element made of inherently flexible material which can be deformed by the actuator along its length (e.g. by being brought from a flat to a circular arc shape or by changing the radius of an arc formed by the adjusting element) and is coupled to the guide element in such a way that the shape of the guide element over its length adjusts to the Adapts the shape of the adjustment element. At least one variable-length actuator extends between two brackets each coupled to the adjusting element or transversely to the crop flow direction between a bracket connected to the housing of the discharge device and the adjusting element, and generates a bending moment acting on the adjusting element.
    BE2019 / 0004
    In other words, the actuator (in particular electrically, hydraulically or pneumatically actuated) deforms a flexible adjusting element. The adjusting element in turn specifies the shape of the guide element, which specifies the discharge direction of the ejection device and thus of the discharge device. Accordingly, the actuator adjusts the curvature of the adjusting element, which is transferred to the guide element. This results in a rounded shape of the guide element in all positions of the guide element without any corners and edges which would hinder the material flow.
    The adjusting element can extend over the entire length of the ejection arrangement or a part thereof. In the second-mentioned case, a region of the guide element that is front or rear or possibly middle with respect to the material flow direction is not adjusted, which in certain embodiments can be useful or at least acceptable from a cost perspective.
    In one possible embodiment, the guide element is made in one piece with the adjusting element. In another embodiment, it would also be conceivable for the guide element on the side of the adjusting element facing the material flow to be detachably (e.g. as an exchangeable wear element) or non-detachably (e.g. as a wear-resistant coating) coupled to the adjusting element. In the first case the guide element can be replaced in the event of wear, while in the second case the guide element would have to be replaced together with the adjusting element. In a further embodiment, the guide element is composed of a plurality of components which are attached to the adjusting element in a roof-tile-like manner, rigidly or movably, and in the case of moving components can be brought into a position in contact with the adjusting element by the material flow (in particular against the force of a spring) are.
    BE2019 / 0004
    It would be conceivable that only a single actuator is present and the adjustment element is guided by an (optional) guide.
    Another possibility is that there are several actuators which act on the adjusting element arranged one behind the other in the material flow direction.
    In the embodiment in which at least one variable-length actuator extends between two brackets each coupled to the adjusting element and generates a bending moment acting on the adjusting element, a plurality of actuators can be arranged spaced apart in the longitudinal direction of the bracket and controlled differently. A plurality of actuators and associated holders can also be arranged one behind the other or next to one another in the crop flow direction and / or transversely thereto.
    A controller can control the actuators in such a way that a desired shape of the adjusting element and thus of the guide element results. This shape preferably corresponds at least approximately to a circular arc, the radius of which can be changed by the actuator or the actuators. In addition, if necessary, several actuators can be arranged laterally next to one another transversely to the material flow direction.
    The guide element can form an upper limit for a material flow flowing through the discharge device, i.e. take the place of a previous chute of a chute. Alternatively or additionally, the guide element can form a lateral boundary for the material flow flowing through the discharge device. In this case, the guide element can comprise or form adjustable side wall end sections on both sides of the material flow, which can be adjusted together and in the same or in opposite directions or independently of one another by one or more actuators.
    BE2019 / 0004
    The invention can in principle be used on any (agricultural) machines with discharge devices, for. B. snow blowers, fodder distributors or harvesters in the form of combine harvesters. However, it can be particularly useful for forage harvesters.

    Fig. 10 is a schematic plan view of an eighth embodiment of an ejection arrangement.
    A harvesting machine 10 shown in FIG. 1 in the manner of a self-propelled forage harvester is built on a frame 12 which is supported by front and rear wheels 14 and 16
    BE2019 / 0004. The harvesting machine 10 is operated from a driver's cab 18, from which a crop pick-up device 20 can be viewed. By means of the crop pick-up device 20 picked up from the ground, z. B. corn, grass or the like is fed through a feed channel 36 with pre-compression rollers 30, 32 to a chopper drum 22, which it chops into small pieces in cooperation with a shear bar 46 and gives it to a conveyor 24. The knives of the chopper drum 22 can be sharpened by a grinding device 42. The material leaves the harvesting machine 10 to a transport vehicle traveling alongside via a discharge device 26 in the form of an ejection elbow. Between the chopping drum 22 and the conveying device 24 there extends a secondary comminution device with rollers 28, 28 ', through which the material to be conveyed is fed tangentially to the conveying device 24.
    The position of the components of the discharge device 26 can be changed by actuators 48, 50 and 58. A first actuator 50 in the form of a hydraulic motor serves to rotate the discharge device 26, which is rotatably mounted on the frame 12 on a rotating ring about the vertical axis. The actuator 50 enables the discharge device 26 to be rotated rearward into the rearward loading position shown in FIG. 1, or to spend them to the left or right of the harvester 10. A second actuator 48 in the form of a hydraulic cylinder is set up to pivot the discharge device 26 about a horizontal axis 34 located at its upstream end. The second actuator 48 thus defines the height of the downstream end of the discharge device 26. Optionally, a further actuator (not shown) can be provided for adjusting the length of the discharge device 26.
    The actuator 48 is a single- or double-acting hydraulic cylinder, the weight of the discharge device 26 making the return movement possible with a single-acting hydraulic cylinder. The actuators 48, 50 and 58 can by means of a
    BE2019 / 0004
    Input device 98 can be controlled, which is located in the driver's cab 18 and can be attached to a driving lever in a different manner than shown, and is connected to a controller 52 which controls the actuators 48, 50 and 58, usually using feedback sensors Detection of the respective position of the actuators. Sensors (not shown) can also be used to control the actuators 48, 50, 58, which detect the position of a transport vehicle and automatically control the actuators in such a way that the crop is deposited at the desired location. The sensors can optically detect the transport vehicle and control the actuators using image processing software. Optical or acoustic (e.g. with ultrasound) or electromagnetic waves, such as radar, can also be used to measure distances. In another embodiment, the harvesting machine 10 and the transport vehicle each have a position sensor, e.g. B. a GPS receiver, whose position signals are used to automatically control the actuators.
    At the outlet end of the discharge device 26, an ejection arrangement 54 is provided, which takes the place of a previous one-part or multi-part ejection flap. The ejection arrangement 54 makes it possible to set the angle at which the harvested material leaves the discharge device 26. The crop can accordingly be deflected more or less far downwards or to the side or to the rear, depending on the rotational position about which the actuator 50 has rotated the discharge device 26.
    For the sake of simplicity, directions in the following, such as front and rear, refer to the crop flow direction, which runs to the right in the figures. The front end of an element is therefore upstream with respect to the crop flow direction and the rear end is downstream.
    According to the first embodiment shown in FIGS. 1 and 2, the ejection arrangement 54 comprises an adjusting element 60 which is made of inherently flexible material, such as spring steel
    BE2019 / 0004 or a wear-resistant plastic or fiber composite material. The adjusting element 60 is rigidly connected at its front end to the rear end of the upper part 66 of the housing of the discharge device 26 (e.g. screwed) and extends it to the rear. On the upper part 66 of the housing of the discharge device 26 there is also a holder 62 which extends rearwards and upwards. Two or more / more actuators 58 'and 58 are attached in series between the holder 62 and the adjusting element 60. The actuators 58, 58 'are each designed as an arrangement with one or more bellows connected spatially one behind the other (cf. DE 10 2011 107 580 A1) and accordingly their length can be adjusted pneumatically. The front actuator 58 'can have a smaller number of bellows than the rear actuator 58, which has to travel a larger adjustment distance. The different adjustment path of the actuators 58 and 58 'can also take place, for example, with an internal or external stop of the actuators 58 and 58' or by different actuation of the actuators 58 and 58 '. A likewise flexible or flexible guide element 56 is attached to the surface of the adjusting element 60 facing the crop flow, be it as a detachable and thus replaceable wear element or as a non-detachable wear coating. It is also conceivable that the adjusting element 60 and the guide element 56 consist of one and the same element.
    The actuators 58, 58 'can be controlled by the control 52 in such a way that the adjusting element 60 and thus also the guide element 56 coupled to it are stepless or in steps between an uppermost position in which the adjusting element 60 and the guide element 56 in FIG. 2 are solid Lines are shown and extend approximately in a straight line and almost do not deflect the crop downward, and adjustable to a lowermost position in which the adjusting element 60 'is shown in broken lines in FIG. In the lowest position, the adjusting element 60 and the guide element 56 extend downward in an approximately circular curve and deflect the crop downward. In the intermediate positions, the adjusting element 60
    BE2019 / 0004 and the guide element 56 (approximately) circular arcs with variable radii. It is therefore used here that the elasticity of the adjusting element 60, even with a limited number of actuators 58, 58 ', which could also be enlarged, always leads to the fact that the adjusting element 60 and thus also the guide element 56 form a relatively round shape, that does not form corners and edges that negatively affect the crop flow. It is also possible for the adjusting element 60 and thus also the guide element 56 to deflect upward or be adjusted further than the uppermost position.
    It should also be noted that the underside of the guide element 56 adjoins approximately flush with the underside of the upper part 66 of the housing of the discharge device 26 or is offset slightly upwards relative to the underside of the upper part 66 of the housing of the discharge device 26, in order to move in the transition area from Part 66 on the guide element 56 to form no edges or projections.
    In the second embodiment according to FIG. 3 there is only a single actuator 58 which is designed as a hydraulic cylinder. The inherently flexible adjusting element 60 and the guide element 56 are made in one piece, although they could also be in two parts, analogous to the first embodiment. The front end of the one-piece adjustment and guide element 60, 56 is connected to the rear end of the upper part 66 of the housing of the discharge device 26 in the manner described with reference to FIGS. 1 and 2. The one-piece adjusting and guiding element 60, 56 is connected to the actuator 58 in the vicinity of its rear end. In addition, a guide 64 is provided which is supported on the holder 62 and cooperates with the one-piece adjusting and guiding element 60, 56 in order to establish a clear relationship between the stroke of the actuator 58 and the position of the rear end of the one-piece adjusting and guiding element 60 To manufacture 56. The guide 64 could possibly also be omitted, for example by suitable positioning of the actuator 58, or it could be designed as a stop against which
    BE2019 / 0004 can adjust and guide element 60 and which is shaped so that it achieves an optimal, predetermined shape. This stop can be carried out interchangeably and can be optimized for the respective crop or harvest situation.
    In the embodiment according to FIG. 3, only a single actuator 58 is provided and one relies on the fact that the one-piece adjusting and guiding element 60, 56 automatically assumes an arcuate shape, with the material thickness of the adjusting and Guide element 60, 56 and the action of the actuator 58 can also form an arc-like shape. Analogously to FIG. 2, a second or further actuators 58 'could also be provided if required.
    The third embodiment of FIG. 4 is again similar to that of FIGS. 1 and 2 (and could also be used in combination with the actuator 58 and the adjusting element 60 of the embodiment of FIG. 3), but the guide element 56 is composed of several components which are composed of one another Cover them like a roof tile in the direction of crop flow. The front ends of the components can be rigidly attached, for example, to the adjusting element 60 and / or to a preceding guide element 56 or can be pivoted freely about an axis running transversely to the plane of the drawing, because during operation the crop flow will be in the position shown, in which they rest on the adjusting element 60, pivot. In the embodiment according to FIG. 4, there is the possibility of executing the components rigidly in themselves, because the adjusting movement of the adjusting element 60 is absorbed by a relative movement of the components of the guide element 56 if they are only rigidly or pivotably attached to the adjusting element 60 with their front ends. However, the components could also be attached to the guide element 60 over a large area if they are designed to be sufficiently flexible. Several components of the guide element 56 could also be arranged side by side in the lateral direction. This is particularly useful for parts coated with hard material that cannot be flexibly bent without damage.
    BE2019 / 0004
    In a further embodiment (not shown), one or more compression springs or one or more torsion springs could be fitted between the guide elements 56, as shown in FIG. 4, which are pivotally mounted at their front ends about axes extending transversely to the plane of the drawing, and the adjusting element 60 be, which bias the guide elements 56 away from the adjusting element 60 (ie downward in FIG. 4). These springs can be attached to or at a distance from the axles.
    FIGS. 5 and 6 show a fourth embodiment of an ejection arrangement 54. The adjusting element 60 can be made in one piece with the guide element 56 or they can be designed separately from one another as in FIGS. 2 or 4. Two actuators 58, 58 'are used, which are arranged one above the other and each extend approximately over the length of the ejection arrangement 54. The ends of the actuators 58, 58 'are connected by brackets 68, 70 to the front and rear ends of the adjusting element 60. A cover 72 made of flexible material, such as rubber or spring steel folded like an accordion, covers the actuators 58, 58 'upwards and possibly to the side. The actuators 58, 58 'each consist of a number of bellows connected mechanically, pneumatically or hydraulically in series.
    The mode of operation of the fourth embodiment is based on the fact that the axial length of the actuators 58, 58 'can be changed by external power, while the actuators 58, 58' only have limited mobility in both transverse directions (ie the vertical direction in FIGS. 5 and 6 and in FIG the direction perpendicular to the plane of the drawing). As can be seen in FIGS. 5 and 6, the different length changes of the actuators 58, 58 ′, which are controlled by the controller 52, make it possible to lengthen (FIG. 6) or shorten (FIG. 5) and simultaneously shorten or lengthen the lower actuator 58 '(FIG. 6) or extend it (FIG. 5). As a result of the different changes in length of the actuators 58, 58, forces and torques act on the brackets 68, 70,
    BE2019 / 0004 which are transmitted to the adjusting element 60 as bending moments which lead to the desired adjusting movement of the adjusting element 60. For this purpose, reference is made to the disclosure of WO 2011/082773 A1 and DE 10 2012 006 564 B3, which are incorporated into the present documents by reference. It would also be conceivable to subdivide the actuators 58, 58 'in the axial direction and to arrange further brackets (not shown) at the intermediate points and to couple them to the adjusting element 60. One of the actuators 58 or 58 ″ could also be omitted and the remaining actuator 58 ″ or 58 alone could generate the bending moment for the adjusting element 60.
    If the adjusting element 60 is variable in length in the axial direction (ie in the horizontal direction in FIG. 5) (for example telescopic or flexible), there is also the possibility with the embodiment of FIGS. 5 and 6 to shorten and lengthen the adjusting element 60 in the axial direction , for which the actuators 58 and 58 'are actuated in the same direction, so that they cover the same adjustment paths in order to extend or retract the adjustment element 60. The guide elements 56 for this embodiment are in particular those according to FIG. 4, inasmuch as they are so long that the following guide elements 56 in the axial direction still overlap even when the adjustment element 60 is pulled out.
    In the embodiment according to FIG. 7, which shows the end region of the discharge chute 26 with a fifth embodiment of an discharge arrangement 54 in plan view, the upper limit of the crop flow formed by the guide element 54 is not replaced by the adjusting element 60 (as in the previous embodiments) Actuator 58 adjusted, but the lateral limitation of the crop flow. For this purpose, adjoining the rear ends of the two side walls of the discharge chute 26 are respectively adjustable side wall end sections 95, which are composed of adjusting elements 60 and guide elements 56 arranged on the inside thereof, analogously to the previous embodiments. The adjustment is made by
    BE2019 / 0004 an actuator 58 which can correspond, for example, to that of FIGS. 2, 4 and 5. The actuator 58 is arranged on the top or bottom of the discharge spout 26 (and outside of the crop flow) and is coupled at both ends to one of the side wall end sections 95, so that the side wall sections 95 move in opposite directions between an extended position (solid lines) and a contracted position (Sidewall end portions 95 'shown in dashed lines) are adjustable. In the contracted position, the crop flow is concentrated, which can be advantageous, for example, when the wind prevails during the loading process, and in the contracted position the crop stream is fanned out.
    The embodiment according to FIG. 8 uses two separate actuators 58, 58 ', each of which is coupled to one of the side wall end sections 95 and is coupled to a central connecting element 96 which is supported on the chute 26. In this embodiment, the side wall end sections 95 can be actuated separately from one another by actuators 58, 58 ′ and thus by the controller 52, or they are connected by valves or controlled by the controller in such a way that they are actuated in opposite directions, as in FIG Sidewall end portions 95 'shown in dashed lines are indicated in order to change the direction of throw. It would also be conceivable to control them in the same direction as in FIG. 7 in order to concentrate or fan out the crop flow.
    The embodiment according to FIG. 9 combines the adjusting element 60 from FIGS. 5 and 6 with the adjustable side wall sections 95 from FIGS. 7 or 8. However, the actuators 58a for adjusting the side wall end sections 95 are arranged on the outside thereof and are connected to the side wall of the Spout 26 coupled. Here is only with adjusting element 60 curved downwards
    BE2019 / 0004 an adjustment of the side wall end portions 95 possible outwards, which can be useful for some applications.
    The embodiment according to FIG. 10 corresponds fundamentally to that according to FIGS. 7 and 8, but the actuators 58 and 58 'are between the lower, outer ends of the side wall sections 95 and one opposite the outer, lateral ends 100, 100' of the discharge spout 26 in the direction of the field chopper 10 to be offset area arranged on the top of the discharge spout 26. The actuators 58, 58 'accordingly deform the side wall sections 95 in the longitudinal direction of the crop flow and in the vertical direction and can move them between a triangularly spread apart position (labeled 95) and a merged position (labeled 95') in which the side wall sections move 95 extend approximately parallel to each other. In this embodiment, care must be taken to ensure that a certain dead center is not exceeded in position 95 ', since otherwise the actuator 58, 58' cannot return to position 95 due to the spring action of the side wall sections 95. However, this problem could be solved by double-acting actuators 58, 58 'pulled into position 95 by spring force. If the side wall sections 95, 95 'were to be made of inherently rigid material, the side wall sections 95, 95' could move inward from the outer, lateral ends 100, 100 'of the discharge spout 26 (to the inner end of the side wall sections 95, 95' ) extending axes are articulated on the upper wall of the discharge spout 26. A spring could be attached there, which counteracts the actuator 58, 58 'and e.g. can be designed as a torsion or tension or compression spring.
    In all of the embodiments, the actuators 58, 58 ′ can optionally be adjusted by electrical, hydraulic, pneumatic means or a combination of two or all of the means mentioned.
