    An arrangement for adjusting an ejection accelerator gap between the enveloping circle described by paddles of a rotor of an ejection accelerator of a forage harvester and a concave portion of a rotor accommodating housing
    The invention relates to an arrangement for adjusting a Auswurfbeschleunigerspalts between the described by paddles of a rotor ejection acceleration of a forage harvester and a concave portion of a rotor housing housing, with an actuator for adjusting the Auswurfbeschleunigerspalts and connected to a sensor control device for controlling the actuator of signals from the sensor.
    State of the art
    Forage harvesters are used in agriculture to pick up parts of plants or whole plants from a field, chop them and finally transfer the chopped plants to a transport vehicle. The transfer operation takes place by means of an ejection acceleration device, which mechanically accelerates the crop shredded by a chopper drum and gives up an ejection chute through which it reaches the transport vehicle in free flight. The ejection accelerator includes a rotor having circumferentially distributed paddles disposed within a housing. The crop is thus passed between a - usually designed as a coated, replaceable wear plate - concave portion of the housing and the paddles through a so-called ejection accelerator gap.
    The distance between the enveloping circle of the paddles and the mentioned concave portion of the housing, i. The size of the ejection accelerator gap affects the achievable throw distance of the crop and the energy requirements of the ejection accelerator. It has already been proposed (EP 1 380 204 A1) to set the ejection accelerator gap automatically to a measure dependent on crop parameters (crop moisture or density) by displacing holders on both sides of the rotor by one or two externally operated actuators on which the rotor rotates is stored. In another embodiment, the supports of the rotor are slidably mounted against the force of a spring from the material flow, wherein the narrowest possible ejection accelerator gap is predetermined by stops which are adjustable by actuators. EP 1 752 037 A1 proposes moving the ejector accelerator gap by automatic, force-actuated displacement of the rotor based on signals from a sensor for detecting the gap width between the rotor
    Eject accelerator and the adjacent wall of the hoistway to adapt to the respective Überladeabstand and EP 1 961 288 A1 proposes to lock the adjustable rotor in the respective position to relieve the adjusting mechanism of the forces acting on the rotor forces.
    Object of the invention
    The object underlying the invention is to improve an arrangement for adjusting an ejection accelerator gap between the enveloping circle described by paddles of a rotor of an ejection accelerating device of a forage harvester and a concave portion of a housing housing the rotor so that it is ensured even after longer service lives, that a desired ejection accelerator gap is maintained. Solution of the task
    This object is achieved according to the invention by the teaching of claim 1, wherein in the other claims features are listed, which further develop the solution in an advantageous manner.
    An arrangement for adjusting an ejection accelerator gap between the enveloping circle described by paddles of a rotor of an ejection accelerating device of a forage harvester and a concave portion of a housing housing the rotor comprises an actuator for adjusting the size of the ejection accelerator gap and a control device connected to a sensor for actuating the actuator. The sensor is configured to generate a signal dependent on the actual size of the ejection accelerator gap and / or on the actual size of the enveloping circle of the paddles. The signal of the sensor thus allows - at least for certain sizes of the ejection accelerator gap, as will be explained below using the example of the vibration sensor - conclusions about the current size of the ejection accelerator gap and / or the diameter of the enveloping circle of the paddles.
    Accordingly, it is not easy to measure the position of the axis of rotation of the rotor relative to the concave region of the housing or vice versa, which is no longer exact when the housing and / or the paddles of the rotor wear out, and a setting of the ejection accelerator gap based thereon by means of the actuator, but a characteristic of the actual dimension of the ejection accelerator gap and / or the enveloping circle of the paddle size is detected. The control device controls the actuator depending on the signal of
    Sensors such that the ejection accelerator corresponds to a predetermined size or at the setting of the ejection accelerator gap at least one possibly changed diameter of the enveloping circle described by the paddles is taken into account. In this way, the Ausstoßbeschleunigerspalt can be adjusted more accurately than in the prior art automatically to a desired value even after longer periods of wear with worn housing or worn paddles.
    The sensor is an inductive distance sensor. Such distance sensors usually include a permanent magnet and a magnetic field sensor, in particular in the form of a coil or a magnetorestrictive sensor. The permanent magnet and the magnetic field sensor are preferably mounted on the outside of the concave portion of the generally magnetically conductive steel housing near the ejector accelerator gap. The paddles passing in the immediate vicinity of the housing, also made of magnetically conductive material (usually steel) influence the magnetic field, so that the magnetic field sensor can detect a change in the magnetic field whose parameters (eg voltage, amplitude or frequency, etc.) from the distance between the magnetically conductive part of the housing and the enveloping circle of the paddles depends. The magnetic field sensor thus provides a signal whose parameters depend on the diameter of the enveloping circle of the paddles. The structure and operation of the magnetic field sensor are comparable to inductive distance sensors, as they are used to determine and adjust the counter-cutting distance on chopping drums of forage harvesters, including the state of the art according to DE 198 12 271 A1 and in the associated. Search Report referenced documents.
    In addition, the control device is connected to a vibration sensor. The vibration sensor detects mechanical or acoustic vibrations whose amplitude greatly increases, in particular, when a paddle strikes against the housing. In particular, the vibration sensor can be associated with a bearing of the rotor or attached to any other location of the housing. The structure and operation of the vibration sensor are similar to knock sensors, as used to determine and adjust the counter-cutting distance on chopping drums of forage harvesters, for which reference is made to the state of the art according to DE 10 2004 016 089 A1 and the prior art discussed there.
    The control device is preferably designed to derive a signal value with regard to the state of wear of the concave region of the housing from the signal of the vibration sensor. Since the housing is usually constructed of an outer steel supporting member and an inner wear coating whose frictional properties differ from the supporting member, the vibration spectrum emitted by the ejection post-accelerator changes significantly (spectrally and over time) as the wear coating is locally worn , This situation is exploited by the control device in order to derive the signal value with regard to the state of wear of the concave region of the housing on the basis of the signal of the vibration sensor. Thus, if the vibration signal indicates a worn wear coating, a corresponding indication can be given visually or acoustically to the forage harvester operator. Alternatively or additionally, the vibration sensor can also serve to detect possible bearing damage of the bearing of the rotor.
    In a preferred embodiment, the rotor is fixedly mounted in a frame of the forage harvester / while the actuator displaces the concave portion of the housing relative to the frame. Of course, there is also the reverse possibility to make the housing frame-fixed and to adjust the rotor by the actuator.
    Preferably, an actuator is provided on both lateral ends of the housing, which is separately controllable by the control device. In order to set a desired ejection accelerator gap at least approximately constant over the width of the ejection afteracceleration device, it is recommended that the control means be operated at appropriate times without harvest throughput, for example at first startup of the forage harvester after a stoppage of the internal combustion engine or during harvest breaks without throughput, e.g. when moving on a field that controls actuators such that initially a first actuator spends the concave portion of the housing at a predetermined distance from the enveloping circle of the paddles. Then, the second actuator adjusts the concave portion of the housing toward the enveloping circle of the paddles until the sensor detects an ejection accelerator gap below a predetermined threshold (ie, a contact between the housing and the paddles when using a vibration sensor) and the associated position control device of the actuator, which can be measured with a position sensor, stores. Subsequently, the second actuator spends the concave portion of the housing at a predetermined distance from the enveloping circle of the paddles, whereupon the first actuator adjusts the concave portion of the housing toward the enveloping circle of the paddles until the sensor detects an ejection accelerator gap below a predetermined threshold (ie when using a vibration sensor, a contact between the housing and the paddles) and the control device, the corresponding position of the first actuator, which can be measured with a position sensor, stores, and finally the control device, the two actuators depending on the two stored positions of the actuators in one spends the predeterminable size of the ejection accelerator gap corresponding position. For this purpose, reference is again made to the disclosure of DE 10 2004 016 089 A1 and the state of the art discussed there
    Technology directed. If the actuators adjust the rotor relative to the housing, the procedure is analog, with the actuators moving the two ends of the rotor.
    On the other hand, it is also possible to use only a single actuator for adjusting the concave portion of the housing, which in particular can engage centrally on a parallel concave portion of the housing or can be coupled by a suitable mechanism with both lateral ends of the concave portion of the housing.
    Furthermore, the control device can perform the adjustment of the actuators time or flow controlled, i. make an adjustment of the ejection accelerator gap again only after a predetermined period of time or processing of a certain flow rate. In this case, an adjustment based only on an inductive distance sensor usually takes place at a higher frequency than the adjustment procedure based on a vibration sensor.
    The predeterminable size of the ejection accelerator gap can be defined or fixed by means of an operator input device and / or a crop sensor for detecting crop properties (cf EP 1 380 204 A1) and / or an overload distance detection device (see EP 1 752 037 A1).
    The arrangement according to the invention is used on a forage harvester which is equipped with a chopper drum and an ejection acceleration device arranged downstream of the chopper drum, which follows an ejection chute in the crop flow direction.
    Ausführunasbeispiel
    With reference to the figures, an embodiment of the invention will be explained. Show it:
    1 is a schematic side view of a forage harvester,
    Fig. 2 is a schematic plan view of the drive assembly of the forage harvester including an ejection accelerating device, and
    Fig. 3 is a flow chart according to which the controller operates.
    FIG. 1 shows a self-propelled forage harvester 10 in a schematic side view. The forage harvester 10 is built on a frame 12 supported by front driven wheels 14 and steerable rear wheels 16. The operation of the working machine 10 is carried out by a driver's cab 18, from which a header 20 in the form of a pickup is visible. By means of harvest header 20 picked up from the ground crop, z. As grass or the like is fed via a feed conveyor 22 with pre-press rollers, which are arranged within a feed housing on the front side of the machine 10, arranged below the driver's cab 18 chopper drum 26, which chops it into small pieces and gives it an ejection accelerator 28. The material leaves the work machine 10 to a transporting vehicle traveling alongside on a by means of externally powered actuators (not shown) about an approximately vertical axis rotatable and adjustable in inclination Auswurfkrümmer 30 with an end-side, adjustable ejection flap. Between the chopper drum 26 and the ejection accelerator 28, a grain processor 24 is arranged with two rollers, which is used in corn crop for striking grains in the crop. As shown, the rolls of the grain processor 24 may be placed in a sufficiently spaced apart position at the grass seed, or they may be removed from the crop flow or removed entirely from the forage harvester. In the following, directional details, such as laterally, downwardly and upwardly, refer to the forward movement direction V of the forage harvester 10, which runs to the right in FIG.
    FIG. 2 shows a top view of the drive arrangement of the forage harvester 10. In the rear area there is an internal combustion engine 32 arranged in the direction of travel V. During operation, the internal combustion engine 32 drives with its crankshaft 34 a longitudinal shaft 36 which is connected to a first bevel gear 38 of an angle gear 40 connected is. A second bevel gear 42 of the angle gear 40 is connected to a transverse shaft 44 which extends through a hollow shaft 48 connected to a pulley 46 on the side remote from the angular gear 40 side of the pulley 46 and is connected there to a coupling 50. The pulley 50 is wrapped by a first drive belt 52, which also wraps around a pulley 54 for driving a rotor 74 of the ejection acceleration means 28 and a pulley 56 for driving the chopper drum 26. The clutch 50 is connected on the output side to the hollow shaft 48 and makes it possible to turn on and off the drive belt 52 and with it the chopper drum 26 and the ejection accelerator 28.
    The pulley 54 is connected to a first end 60 of a drive shaft 58 for driving the ejection accelerator 28. The second end 62 of the drive shaft 58 is connected to a pulley 64, which drives two pulleys 68 (of which only one is shown in FIG. 2, but see DE 196 03 928 A1) during corn harvesting via a second drive belt 66 for their part, only drive the kernel processor 24 rolls during the corn harvest.
    The rotor 74 of the ejection accelerator 28 includes a number of paddles 70 extending transversely of the crop flow direction which are rigidly connected to a hollow support shaft 76 by support disks 72 extending radially to the drive shaft 58, three of which are distributed across the width of the ejection accelerator 28. The paddles 70 each extend between two support disks 72 and are attached to them. The support shaft 76 encloses the drive shaft 58 concentrically and is rotatably fixed to the drive shaft 58 at the ends by flanges 82.
    The rotor 74 of the ejection accelerator 28 is disposed within a hollow housing 84 which completely encloses the rotor 74 with the exception of a lower front inlet 86 and an upper outlet 86 for the crop (and possibly additional openings for air supply). The rear, concave-shaped portion 90 of the housing 84 is composed of an outer, supporting part 92 made of steel and an inner, the rotor 74 facing wear coating 94 of a relatively hard material (eg, a hard metal powder, see EP 1 975 278 A1) together , The region 90 and the rotor 74 define one
    Ausstoßbeschleunigerspalt 96 through which the entire crop has to pass on its way from the cutterhead 26 to the chute 30 through. The rear, concave shaped portion 90 of the housing 84 is mechanically separated from the rest of the housing 84 and by two arranged at its lateral ends, independently controllable actuators 98, 98 'in the direction of the rotor 74 to and away adjustable. The actuators 98, 98 'are in the illustrated embodiment, electric motor actuated linear actuators, but could also be as a hydraulic cylinder or the area 90 about a lower or upper axis of rotation pivoting electric or hydraulic motors.
    The drive shaft 58 of the rotor 74 is the housing 84 adjacent by bearing 100 on the frame 12 and a support 12 connected to the frame 102 supported. On the holder 102, a vibration sensor 104 for detecting mechanical vibrations of the rotor 74 and the housing 84 is arranged. A suitable vibration sensor 104 is described in DE 10 2009 000 351 A1 and DE 10 2004 016 089 A1. A signal output of the vibration sensor 104 is connected to a controller 106 (see Fig. 1). In particular, the vibration sensor 104 is adapted to emit signals indicative of such contact in the event of contact between the rotor 70 and the region 90. Its operation can therefore be compared with knock sensors, which are used in the prior art in adjusting the distance between the counter-blade and the cutterhead 22. The vibration sensor 104 could alternatively be attached directly to the housing 84 or to the concave area 90, as shown in FIG.
    The control device 106 is also connected to the actuators 98, 98 'and the actuators 98, 98' associated position sensors 108,108 'for detecting the respective position of the actuator 98. The position sensors 108, 108 'can be designed in the form of coding discs with light barriers or as potentiometers.
    Furthermore, the control device 106 is connected to the signal output of an inductive distance sensor 110, which in the illustrated embodiment comprises a permanent magnet 112 and a wound around it induction coil 114, which could also be designed as a magnetorestrictive sensor. The inductive distance sensor 110 is disposed on the outside of the rear concave shaped portion 90 of the housing 84. The inductive distance sensor 110 outputs signals to the control device during operation, which contains information about the distance between the (magnetically conducting) supporting part 92 and the enveloping circle of the (magnetically conductive) paddle 70. The wear coating 94, in turn, is generally not magnetically conductive and its thickness (and the distance between it and the paddles 70) can not be detected by the inductive proximity sensor 110.
    Furthermore, the control device 106 is provided with an operator input device 116 arranged in the cabin 18, a position determination device 118 for receiving signals from satellites of a position determination system (GPS, Glonass, Galileo or the like) and an image processing system 120 of a (stereo) attached to the discharge manifold 30. Camera 122 connected. In addition, the controller 106 is connected to a sensor 124 (in the form of a near-infrared spectrometer) for detecting the crop moisture and a sensor 128 for detecting the position of the upper pre-press rollers of the intake conveyor 22, which detects the respective crop throughput.
    3, the arrangement comprising the control device 106, the actuators 98, 98 'and the sensors 104 and / or 110 for adjusting the ejection accelerator gap 96 between that of the paddles 70 of the rotor 74 of the ejection accelerating device 28 results in the flowchart of FIG 28 of the field harvester described and the concave portion 84 of the rotor 74 receiving housing 84th
    After the start in step S300 (initialize, start-up of the controller 106 after switching on the ignition of the forage harvester 18 and closing the clutch 50), step S302 follows, in which a target value for the ejection accelerator gap 96 is determined. This setpoint can be determined on an operator input in the operator input device 116 or the crop throughput detected with the sensor 128 and / or the crop moisture detected by the sensor 124 or by the camera 122 and the image processing system 120 (possibly using signals from the position determination system 118 and a transport vehicle via radio transmitted position data) determined Überladeabstand be determined. It would also be conceivable in step S302 to read out a fixed setpoint value for the ejection accelerator gap 96 from a memory of the control device 106.
    This is followed by the step S304, in which it is queried whether crop currently passes through the forage harvester 10, for which purpose the sensor 128 is used. If no crop is currently being processed by the forage harvester 10, the step S306 follows, otherwise the step S310 described below.
    In step S306, a setting procedure for adjusting the ejection accelerator gap 96 to the target value is performed. To do this, the actuator 98 'is caused to pull off the region 90 from the rotor 70 and then causes the actuator 98 to move the region 90 toward the rotor 70 until the vibration sensor 104 indicates that contact between the region 90 and the rotor 70 is present. The associated position of the actuator 98 is determined and stored by means of the position sensor 108. Then, the actuator 98 pulls the region 90 away from the rotor 70 again and the process is repeated in analogy with the actuator 98 'until the vibration sensor 104 indicates that there is contact between the region 90 and the rotor 70. The associated position of the actuator 98 'is by means of
    Position sensors 108 'determined and stored. Then, the actuator 98 'retracts the area 90 from the rotor 70. After this process, it is known in which positions of the actuators 98, 98 'in each case a contact between the region 90 and the rotor 70 is present. This information and the setpoint distance then serve to actuate the actuators 98, 98 'in such a way, as a rule using the signals of the position sensors 108, 108', that the area 90 assumes a discharge accelerator gap 96 that is constant over the width and corresponds to the desired value.
    In step S308 following step S306, the now present signal of the inductive distance sensor 110 or a value derived therefrom is stored. It is followed again by step S302.
    In step S310 following step S304 in the case of crop throughput, a query is made as to whether the output value of the inductive distance sensor 110 still corresponds to the current setpoint value for the ejection accelerator gap 96. Accordingly, if the setpoint value for the ejection accelerator gap 96 has not changed since the last pass of step S308, it is simply queried whether the output value of the inductive displacement sensor 110 corresponds to the value stored in step S308. Meanwhile, when the setpoint value for the ejection accelerator gap 96 has changed meanwhile, the current signal value of the inductive distance sensor 110 is converted into a value for an ejection accelerator gap 96 by the controller 106 (e.g., a fixed or learned table or equation). If the actual value of the ejection accelerator gap 96 is equal to the set value plus / minus hysteresis, step S302 follows directly, otherwise step S312. It should be noted that step S310 may not be performed until steps S306 and S308 have been completed. The latter are therefore compulsorily performed before S310 is run through.
    In step S312, the actuators 98, 98 'are controlled by the control device 116 in such a way that they spend the concave region 90 of the housing 84 in the position required to achieve the desired value of the ejection accelerator gap 96. Since the current value and the setpoint value of the ejection accelerator gap 96 are known from the step S310, the adjustment can be made simply by means of the signals of the position sensors 108, 108 ', and / or by using current signals from the inductive distance sensor 110, which also contains information about the respective position of the enveloping circle of the paddles 70 with respect to the area 90 (and vice versa) included. In step S312, the two actuators 98, 98 'are generally driven synchronously and in the same amount of movement. In this way, the wear of the paddle 70 is continuously taken into account.
    Various modifications of the method of FIG. 3 are possible. Thus, between steps S304 and S306, another query could be made as to whether the last adjustment of area 90 is longer than a certain time value (eg one hour) or a certain crop throughput (eg 10001 or m3), and step S306 only occur when this value is exceeded. Otherwise, step S302 follows directly. In one possible embodiment, the step S310 is also time or throughput controlled and performed at a higher frequency than the step S306 only when no crop is being guided by the Nachbeschleunigungseinrichtung 28 in order to avoid any falsification of the measurements by the crop.
    Furthermore, the signals of the vibration sensor 104 can be continuously monitored by the control device 106, whether just harvested by the
    Post accelerator 28 (e.g., using sensor 128), and then the sensed vibrations indicate that the wear coating 94 is locally worn, since in this case other mechanical vibrations are caused by the crop and paddles 70 than when the wear coating is intact. Since the wear coating 94 is significantly harder than the supporting part 92, the latter is hollowed out as soon as the wear coating 94 is perforated. When hollowing out, sharp cutting edges are created from wear material that disturb the crop flow. The resulting noise is detected by the vibration sensor 104.
    At the same time or alternatively, the signals of the vibration sensor 104 can be continuously monitored by the control device 106 as to whether they indicate damage to the bearings 100 (see DE 10 2009 000 351 A1).
    Finally, it would also be possible to use only a single actuator 98, which acts centrally on the concave portion 90 of the then equipped with a parallel guide housing. The controller 106 would then act to instruct the actuator 98 in step S306 to deliver the region 90 until the vibration sensor 104 detects contact between the region 90 and the paddles 70 and then retracts the region 90 about the desired ejection accelerator gap 90 ,
    As a result, a more accurate value is provided by the sensors 104 and / or 110 over the ejection accelerator gap 96 or the diameter of the enveloping circle of the paddles 70 than heretofore based on which the controller 106 may spend the region 90 in an appropriate energy saving position.
