    Control arrangement for a grinding device and / or device for adjusting the position of a shear bar
    Feldhäcksle rs
    The invention relates to a control arrangement for a grinding device and / or a device for adjusting the position of a shear bar of a forage harvester and a forage harvester equipped therewith.
    State of the art
    Forage harvesters are used to plant or their
    Pick up fruit stands from a field and cut them into small pieces. The plants standing in the field are usually cut off from the roots remaining in the ground by means of a suitable harvesting attachment and fed to a feed channel of the forage harvester. Alternatively, the plants can be cut off and swathed in previous steps and picked up by means of a pick-up, or only the fruit stands are separated from the plants and conveyed into the feed channel. In the feed channel, the crop mat picked up by the header is pre-compacted by interacting pairs of pre-press rollers that feed the crop mat to a chopper drum, with a number of chopping knives distributed around its circumference (and possibly across its width). The chopping knives cut the crop into small pieces together with a shear bar. The chopped crop (and in particular corn kernels contained therein) is optionally further chopped by means of a post-processing device, conveyed into a discharge chute by means of a post-accelerator and loaded onto a transport vehicle. The chopped crop is used in particular as feed for livestock or for biogas production.
    When cutting the crop, in addition to the sharpness of the chopping knife, the distance between the cutting edge is the
    BE2017 / 0155
    Chopping knives and the shear bar are of great importance in order to achieve a good cutting result in an energy-saving manner. For this purpose, the chopper knives are subjected to a grinding process after they have been installed for the first time and also from time to time, in which a grindstone interacts with the rotating chopper drum. It is then ensured that all cutting edges are sharp and have the same distance from the axis of rotation of the chopper drum for all chopper knives. The position of the shear bar is usually set automatically.
    In the prior art, the grinding process is initiated when an operator believes that the chopping knives are no longer sufficiently sharp. However, such subjective approaches have the disadvantage that they are relatively prone to errors, which means that in many cases harvesting takes place with blunt knives or the chopping knives are ground too early with loss of material. It has therefore been proposed to detect the sharpness of the chopping knife by means of an inductive sensor (DE 10 201 1 005 317 A1), on the basis of whose signals a computer can automatically initiate a grinding process and determine the required grinding intensity. Since a complete grinding process is relatively time-consuming and can take a few minutes, especially if the chopper drum is to be rotated in the opposite direction to the direction of rotation during harvesting (see DE 10 2009 003 242 A1), it usually does not make sense during an ongoing harvesting process. to interrupt this for grinding. However, if you wait too long for grinding, the result is high energy consumption during cutting.
    It has already been proposed to carry out the grinding process while driving on the road (DE 10 2009 029 675 A1) or while the forage harvester is not in operation, e.g. when driving on the headlands (EP 1 862 061 Al) or when not harvesting during work (EP 2 225 931 Al). However, there is the disadvantage with these approaches that either only very short periods of time are available for grinding, e.g. at the
    BE2017 / 0155
    Turning in the headlands or that the driver needs to know how long he has to harvest again and decides based on whether to initiate a grinding process or not. However, it is not foreseeable in every harvest situation how long a harvest break will last. A harvest break due to the absence of transport vehicles may take longer than expected if the transport vehicle driver has to wait at a level crossing or if the transport vehicle breaks down at a location that cannot be seen by the respective field. Inexperienced drivers usually do not know how long it will take them to drive from one field to another. There is therefore the disadvantage that it is difficult for the operator of a forage harvester in the prior art to estimate whether he should initiate a grinding process or not. The same problem exists with regard to the setting of the shear bar, in which the shear bar is correctly positioned again in relation to the enveloping circle of the chopping knives in order to provide a sufficiently narrow grinding gap.
    EP 2 428 669 A2 proposes to trigger the regeneration of a particle filter of an internal combustion engine of a self-propelled harvesting machine automatically using a route planner, which provides information regarding the work to be done on a route and the speeds to be traveled on the route. However, this procedure cannot take the status of the transport chain into account either.
    Object of the invention
    The object on which the invention is based is seen in providing a control arrangement for a grinding device and / or a device for adjusting the position of a shearbar of a forage harvester which does not have the mentioned disadvantages or does so to a reduced extent.
    solution
    BE2017 / 0155
    This object is achieved by the teaching of
    Claims 1 and 8 solved, in the further
    Features are listed that further develop the solution in an advantageous manner.
    A control arrangement for a grinding device and / or a device for adjusting the position of a shearbar of a forage harvester comprises a control unit which is further connected to a computer of a planning system which is programmed, the control unit data relating to the areas to be harvested by the forage harvester and data relating to the transport chain to provide for the removal of the crop. The control unit is programmed to use the data of the planning system to identify at least one future operating time of the forage harvester during which the forage harvester will not pick up any crop and the length of time for a duration predicted on the basis of the signals from a sensor for detecting the sharpness of chopper knives of a chopper drum of the forage harvester a grinding operation of the chopper drum and / or an adjustment procedure for the shear bar is sufficient, and to initiate a grinding operation of the chopper drum and / or an adjustment procedure for the shear bar during the identified operating time (s).
    In other words, a planning system provides data regarding the areas to be harvested by the forage harvester and the transport chain, which is available for harvesting a field. The control unit of the forage harvester uses this data to determine when in the future one or more longer operating times of the forage harvester can be expected without harvesting crops, and compares the length of time of these operating times with that predicted using signals from a sensor to detect the sharpness of the chopper knives Duration of a grinding operation of the chopper drum and / or the time for a shear bar adjustment procedure. Sufficiently long expected operating times are used to grind the
    BE2017 / 0155
    Chop the drum or adjust the position of the shear bar. In this way, those mentioned at the outset
    Disadvantages of the prior art avoided.
    The planning system can be programmed to supply the control unit with the following data relating to the transport chain: number of transport vehicles and their current position, loading capacity of the transport vehicles, distances to be covered between the areas to be harvested and a storage location for the crop (preferably including the traffic situation there, such as possible traffic jams or other traffic obstructions, such as broken down vehicles, accidents, temporary or permanent road closures, black ice, defective traffic signs or closed railway barriers) and associated speeds of the transport vehicles and / or the capacity of a compressor for crops stored at the storage location.
    The planning system can be programmed to supply the control unit with data regarding the position of the areas to be harvested and the associated stock density. The control unit can use the stock densities (and their expected effect on the sharpness of the chopping knives) to extrapolate the sharpness of the chopping knives based on the data of the planning system to the identified operating time at which the grinding process is to take place, in order to determine the length of the grinding process to calculate more precisely.
    The control unit can be set up to initiate the grinding process and / or the shear bar setting procedure without operator input or after a message is displayed on a user interface and a confirming operator input.
    The control unit can be operable, the future operating time of the forage harvester during which it is not harvested
    BE2017 / 0155 begins to update as the harvesting process progresses using updated data from the planning system.
    The control unit can be operable to activate a shear bar adjustment procedure after a grinding process and / or in the event that a sufficiently long operating time for a grinding process cannot be identified for a predetermined period of time.
    The control unit can be operable to determine the duration of the grinding process on the basis of the type of crop and / or the type of chopping knife and / or the type of counter-knife setting procedure depending on the duration of the grinding process and / or on the distance between the counter-knife and the enveloping circle at the beginning of the counter-knife setting procedure to choose the chopper drum. These features are independent inventions which would also be conceivable without planning the time of the grinding and / or counter-cutting edge setting process.
    The sensor can emit absolute or relative focus signals.

    Forage harvester and transport vehicle
    FIG. 1 shows a self-propelled forage harvester 10 and a first transport vehicle 12 in the manner of a self-propelled tractor, which pulls a trailer 16, which comprises a loading container 18, by means of a drawbar 14.
    The forage harvester 10 is built on a frame 20 which is supported by front driven wheels 22 and steerable rear wheels 24. The harvesting machine 10 is operated from a driver's cab 26, from which a harvesting attachment 28 in the form of a corn mowing attachment can be seen, which is attached to an intake duct 30 on the front of the harvesting machine 10. Crop material picked up by a field 34 by means of the harvesting attachment 28 is fed via a feed conveyor arranged in the feed channel 30 with pre-pressing rollers to a chopper drum 36, which, in cooperation with a shear bar 140, the position of which can be adjusted relative to the enveloping circle of the chopper knife 144 by means of a device 154 in chops small pieces and feeds them to a blower 38. The chopper blades 144 of the chopper drum 36 can be ground by a grinding device 142. Between the chopper drum 36 and the blower 38, a post-shredding device 42 with two grain processor rollers extends. The aforementioned, drivable units of the forage harvester 10 and the header 28 are driven by means of an internal combustion engine 44.
    The material discharged from the blower 38 leaves the harvesting machine 10 to the loading container 18 traveling alongside it via a discharge device which consists of a stationary discharge chute 45, which directly adjoins the blower 38 upwards, and one by means of a first, externally powered actuator 46
    BE2017 / 0155 is composed of a spout 40 which can be rotated about the vertical axis and whose inclination can be adjusted by means of a second, power-operated actuator 48, the direction of the discharge of which can be changed by a flap 50, the inclination of which can be adjusted by means of a third, power-operated actuator 52. 1 shows the discharge spout 40 and the flap 50 in their transport position, into which they are placed, for example, when the forage harvester 10 is traveling on a road. During the harvesting process, the discharge chute 40 is raised by means of the actuator 48 and either rotated to one side of the harvesting machine 10 by means of the actuator 46 if, after mowing, there is sufficient space to the side of the harvesting machine 10 for the transport vehicle 12 in a harvested area 56 of the field, or it remains in the rearward-facing position according to FIG. 1 when a lane is first cut in or around the field.
    The transport vehicle 12 and a further transport vehicle 12 'shown in FIG. 3 and the trailers 16, 16' pulled therefrom are of conventional construction. The transport vehicles 12, 12 'each comprise front steerable wheels 64 and rear driven wheels 66 which are supported on a frame 68 which carries a driver's cabin 70.
    FIG. 3 shows the forage harvester 10 and the transport vehicle 12 in a top view. It can be seen that the forage harvester 10 travels along a crop edge 54 which represents a boundary between the harvested area 56 of the field 34 and the still standing crop 60 of the field 34 which is covered with maize plants 58 and which the plants 58 harvest. The first transport vehicle 12 travels on the harvested part 56 of the field parallel to the harvesting machine 10 along a path on which the plants chopped by the harvesting machine 10 pass through the discharge device into the first loading container 18. The transport vehicle 12 must therefore always move parallel to the harvesting machine 10; As mentioned above, the transport vehicle 12 can, however, in particular when entering the field
    BE2017 / 0155 also drive behind the harvesting machine 10, since there is still no harvested part 56 of the field 34 on which the transport vehicle 12 could drive without damaging the plants standing there. While the first loading container 18 of the first transport vehicle 12 is being infested, the second transport vehicle 12 'is currently on a road 152 during the return journey from an unloading point 146, at which the crop is unloaded. The unloading point 146 is designed as a flat silo and the crop is compacted there by a compacting vehicle 148 with a tool 150, which can be a roller.
    The forage harvester 10 is steered by a driver seated in the driver's cab 18 or by a steering device which is known per se and works automatically. The transport vehicle 12 is also equipped with a steering device described in more detail below in order to facilitate or automate parallel driving to the harvesting machine 10 in the field.
    Position determination, control of the transport vehicle
    The forage harvester 10 is equipped with a first position determining device 72, which is located on the roof of the cabin 26. A first radio antenna 74 is also positioned there. The first transport vehicle 12 is equipped with a second position determining device 76, which is located on the roof of the cabin 70. A second radio antenna 78 is also positioned there. In addition, the harvesting machine 10 is equipped with a sensor arrangement 126, which is attached to the flap 50 at the outer end of the discharge spout 40 and serves to detect the contours of the loading containers 18, 18 ′ and / or their fill level with harvested material. The sensor arrangement 126 can be a field of view, two-dimensionally scanning its ultrasound or laser range finder, or it can be a three-dimensional (PMD) camera, or two cameras that generate a stereo image, or a two-dimensional one Camera with
    BE2017 / 0155 is combined with a range finder scanning the visual field.
    The output signal of the sensor arrangements 126 and / or 126 'is processed by a processing circuit 130 (cf. FIG. 3).
    Reference is now made to FIG. 3, in which the individual components of the arrangement for controlling the overloading of the harvested crop from the harvesting machine 10 to the loading containers 18, 18 'including the sensor arrangements 126 and the position determining devices 72, 76 and the steering devices of the transport vehicles 12, 12 'and the forage harvester 10 are shown schematically. On board the forage harvester 10 there is the first position determining device 72, which comprises an antenna 80 and an evaluation circuit 82 connected to the antenna 80. The antenna 80 receives signals from satellites of a positioning system, such as GPS, Galileo or Glonass, which are fed to the evaluation circuit 82. The evaluation circuit 82 determines the current position of the antenna 80 on the basis of the signals from the satellites. The evaluation circuit 82 is also connected to a correction data reception antenna 84 which receives radio waves emitted by reference stations at known locations. On the basis of the radio waves, the evaluation circuit 82 generates correction data to improve the accuracy of the position determination device 72.
    The evaluation circuit 82 transmits its position data to a computer device 88 via a bus line 86. The computer device 88 is connected via an interface 90 to a receiving and transmitting device 92, which in turn is connected to the radio antenna 74. The receiving and transmitting device 92 receives and generates radio waves which are picked up or emitted by the antenna 74.
    Analogously, there is a second position determining device 76 on board the transport vehicles 12, 12 ″, which connects an antenna 94 and one connected to the antenna 94
    BE2017 / 0155
    Evaluation circuit 96 includes. The antenna 94 receives signals from satellites of the same positioning system as the antenna 80, which are fed to the evaluation circuit 96. The evaluation circuit 96 determines the current position of the antenna 94 on the basis of the signals from the satellites. The evaluation circuit 96 is also connected to a correction data reception antenna 98 which receives radio waves emitted by reference stations at known locations. On the basis of the radio waves, the evaluation circuit 96 generates correction data to improve the accuracy of the position determination device 76.
    The evaluation circuit 96 transmits its position data to a computer device 102 via a bus line 100. The computer device 102 is connected via an interface 104 to a receiving and transmitting device 106, which in turn is connected to the radio antenna 78. The receiving and transmitting device 106 receives and generates radio waves which are picked up or emitted by the antenna 78. The receiving and transmitting devices 90, 106 and the radio antennas 74, 78 can transmit data from the computing device 88 to the computing device 102 and vice versa. The connection between the radio antennas 74, 78 can be direct, e.g. B. in an approved radio range such as CB radio or the like, or be provided via one or more relay stations, for example if the receiving and transmitting devices 90, 106 and the radio antennas 74, 78 according to the GSM standard or another suitable standard work for mobile telephony.
    The computer device 102 is connected to a steering device 108 which controls the steering angle of the front, steerable wheels 64. In addition, the computer device 102 transmits speed signals to a speed setting device 110, which controls the speed of the transport vehicle 12, 12 ″ by varying the engine speed of the transport vehicle 12, 12 ″ and / or the gear ratio.
    BE2017 / 0155
    In addition, the computer device 102 has a permanent one
    Memory 120 connected.
    During the harvesting operation, the processing circuit checks the signals of the sensor arrangement 126 to determine whether the harvested material gets into the interior of the loading container 18. If necessary, the actuators 46, 48, 52 are adjusted and / or the steering device 108 and the speed setting device 110 of the transport vehicle 12 or 12 'are controlled such that the crop is overloaded with as little loss as possible. If the loading container 18 or 18 'of the transport vehicle 12 or 12' is sufficiently filled, its driver takes control and drives to the unloading point 146, while the other transport vehicle 12 'or 12 takes over the (automatic) takeover of the crop. In this regard, reference is made to the disclosure of DE 10 2012 211 001 A1. In a simpler embodiment, the actuation of the actuators 46, 48, 52 by the driver of the forage harvester 10 and the speed specification and steering of the transport vehicles 12, 12 ″ could be carried out permanently by their drivers.
    Grinding the chopping knife and setting the shearbar
    The forage harvester 10 is equipped with a schematically illustrated sensor 164, which makes it possible to provide a signal regarding the sharpness of the chopper blades 144 of the chopper drum 36. In this regard, reference is made to the disclosure of DE 10 2011 005 317 A1, which is incorporated by reference into the present documents. The sensor 164 is connected to a control unit 156, which in turn is connected to the computer 88 and an operator input device 158.
    A planning system includes a computer 160, which can be located anywhere. The computer 160 can be designed as a portable mobile device or a fixed computer or with
    BE2017 / 0155 can be integrated into the control unit 156. The computer 160 is equipped with a transmitting and receiving unit and an antenna 162. Before the start of a harvesting process, the computer 160 is loaded with data relating to the harvesting logistics, which relate, for example, to the location and size of the field 34 and the location-specific stock density, which can originate from a previous harvesting process and / or by means of remote sensors (drone, plane or satellite with camera) ) were determined. During the harvest, the computer 160 continuously receives position reports from the forage harvester 10 (via the radio antenna 74), from the transport vehicles 12, 12, (via the radio antennas 78) and also operating status information from the compressor vehicle 148, which is also analogous to the transport vehicles 12, 12 ' a positioning device and a radio antenna. The planning system is used in a manner known per se to first plan the use of the forage harvester 10, the transport vehicles 12, 12 'and the compressor vehicle 148 and to monitor it during the harvesting process (see EP 2 174 537 A1). The paths of the forage harvester 10 and the transport vehicles 12, 12 'can be planned in detail in detail via the field 34 and the road 152.
    The control unit 156 proceeds with the control of the grinding device 142 according to the flow diagram of FIG. 4. After the start in step 400, step 402 takes place, in which the control unit 156 sets up a schedule for the forage harvester 10. Accordingly, it is planned (in relatively small steps, e.g. every second) which activity the forage harvester 10 will perform in the future. On the one hand, the shape and location of the field 34 including its topography and the existing crop 60 including its crop density are taken into account in order to determine when the forage harvester 10 will be located at which location in the field 34, preferably taking into account the route to be taken via the road and the time of the start of work and possible changeover times from road to field operation. If several fields are to be harvested, these and the associated conversion times of the forage harvester 10 are also taken into account. In step 402, it is also taken into account whether
    BE2017 / 0155 at least one transport vehicle 12 or 12 ″ is available or possibly both transport vehicles 12, 12 ″ at the same time
    Unloading point 146 or on street 152. The data for the
    Step 402 is the control unit 156 from the computer 160 of the
    Planning system supplied via the radio antennas 162 and 74.
    In the following step 404, the control unit 156 examines whether the forage harvester's schedule includes a pause for the foreseeable future, i.e. a period of time during which, due to the transport logistics, the crop should not be picked up and processed. If there is no such pause, the process continues with step 402, otherwise with step 406. In step 406, the control unit 156 uses the signals from the sensor 164 to calculate how long the time period T would have to be in order to restore the chopper 144 to an acceptable state of sharpness to spend. For this purpose, reference is made to the disclosure of DE 10 2011 005 317 A1, which is incorporated into the present documents by reference. Since the time of grinding is only in the future, in step 406 the further wear of the chopper blades 144 that was still expected is preferably taken into account, for which purpose the schedule from step 402 and the known, local stock densities can be used.
    In the following step 408, a query is then made as to whether the time period T is greater (or equal) to the pause identified in step 404. If this is not the case, step 412 follows, otherwise step 410 follows, in which (as soon as the expected pause actually occurs) a grinding process is carried out by means of the grinding device 142, preferably after a corresponding message is displayed on the operator input device 158 and a confirmation input from the driver the forage harvester 10 was obtained. When grinding, the chopper drum 36 can be rotated backwards, cf. DE 10 2009 003 242 Al. Finally, step 414 follows. The expected time of a grinding process can also be displayed even if it was calculated in step 408.
    BE2017 / 0155
    In step 412, a query is made as to whether the identified pause is greater than a time TGgs that is required to adjust the shear bar 140. If this is the case, step 414 follows, in which (as soon as the expected pause actually occurs) an adjustment procedure for the shear bar 140 is carried out, which is carried out in a manner known per se (see DE 10 2004 016 089 A1 or DE 10 2013 201 633 B3) can be carried out by a device 154 for adjusting the shear bar in order to bring the shear bar 140 into a suitable position relative to the enveloping circle of the chopper blades 144. As a result, the chopping knives 144 are not sharpened, but the distance to the shear bar 140 is reduced, which contributes to reducing the wear on the chopping knives 144.
    The device 154 for adjusting the shear bar 140 can use the signals from the sensor 164 in order to check the current distance between the shear bar 140 and the enveloping circle of the chopper blades 144 and to adjust the shear bar 140 based thereon. The value of the resetting of the shear bar 140 can be calculated by the control unit 156 on the basis of the shear bar distance to the chopping knife 144 that is currently calculated on the basis of the signals from the sensor 164, on the basis of a stored nominal distance of the shear bar after the normal, automatic shear bar setting process and, if appropriate, on the basis of a Feedback by speed sensors in the servomotors of the shear bar adjustment device 154. The control unit 156 can carry out the automatic adjustment of the shear bar 140 such that the distance does not become greater than a value stored in the control unit 156 and does not become less than the nominal distance. Accordingly, there is no need for contact between shear bar 140 and chopper blades 144 (as described in DE 10 2011 005 317 A1).
    Alternatively, you can use conventional knock sensors when adjusting the shear bar to determine contact between shear bar 140 and chopper blades 144 and the
    BE2017 / 0155
    Shear bar 140 is then pulled back by a defined distance (see DE 10 2004 016 089 Al or DE 10 2013 201 633 B3). The knock sensor mentioned can also be used to calibrate the sensor 164 (which is used according to DE 10 2011 005 317 A1 for determining the sharpness and distance of the chopper blades 144), as was described using the example of a blower in DE 10 2012 223 432 B3.
    Step 414 is followed again by step 402.
    Step 414 can also take place if, according to the result of step 408, no grinding process can be carried out for the foreseeable future.
    In step 414 it would be conceivable, depending on whether and, if necessary, how intensively the chopping knives 144 were ground in the previously carried out step 410 (and / or how large the distance between the enveloping circle of the chopping knives 144 and the shear bar 140 detected by the sensor 164). to use different setting procedures of the shear bar 140 or to suggest it to the operator for selection via the operator input device 158. Thus, a pure parallel adjustment could take place if the chopper blades 144 were not ground or only slightly (or the mentioned distance between the counter blade 140 and the envelope circle of the chopper blades 144 is smaller than a threshold value), and a more complex adjustment of the counter blade 140 with realignment (see DE 10 2004 016 089 A1 or DE 10 2013 201 633 B3) if a grinding process that lasts longer than a threshold value was carried out in step 410 (or the mentioned distance between shear bar 140 and the enveloping circle of the chopper blades 144 is greater than a threshold value) , An adjustment of the shear bar 140 in the manner described can moreover also take place independently of the data of the planning system and can be carried out by the control unit 156, for example, when the forage harvester is taking shorter breaks, e.g. in the
    BE2017 / 0155
    Headlands or when moving on a field or at a
    Road trip can be arranged.
    The length of the grinding process in step 410 can be predetermined by the control unit 156 on the basis of the signals from the sensor 164, as described in DE 10 2011 005 317 A1. It can also be taken into account what type of crop and chopper 144 are. By means of appropriate operator input into the operator input device 158 or a suitable sensor for detecting the type of crop or the type of header or the chopper knife 144, the control unit 156 can be informed, for example, whether the chopper knife 144 should be used for grass or for maize. In the case of maize, a better sharpening of the chopping knives 144 than in the case of grass can be provided in this way, so that the control unit 156 will provide a grinding process for maize earlier and / or carry out a longer grinding process than for grass.
    The planning of step 402 is preferably updated continuously based on the current progress of the harvesting process, i.e. the current positions of the forage harvester 10 and the transport vehicles 12, 12 '. Information regarding the state of the road 152, e.g. with heavy traffic or adverse conditions, and / or information regarding the progress of the compressor vehicle 146 are taken into account. The schedule of step 402, which is initially only theoretically available, is therefore increasingly adapted to the actual progress of the harvesting process, depending on the actual progress of the harvesting process.
    If, in the flow chart of FIG. 4, there is no suitable, sufficiently long pause in step 408 for a very long time to grind the chopper blades 144 in a single grinding operation, step 410 can be divided into several pauses, which were determined in step 402 , Here, (with a sensor 164 which is able to emit relative focus signals)
    BE2017 / 0155 should be carried out in such a way that first (step 408) it is planned how long the grinding process should last in total. It can be assumed here that initially completely sharp chopper blades 144 are present and the control unit 156 detects the (relative) change in the signal of the sensor 164 compared to the original one, based on the measurements of the sensor (preferably taken during times when the crop is not passing through, for example in the headlands) Signal the decrease in sharpness and use this decrease in sharpness to calculate the grinding time. The planned grinding time is achieved cumulatively in the subsequent, multiple runs of steps 410. Alternatively, one could proceed in such a way that the control unit 156 detects the sharpness of the chopper blades 144 (as absolute values) directly on the basis of the signal from the sensor 164 and, based on this, evaluates and applies suitable grinding times during the multiple passes of step 410. The end of the grinding time can then be recognized on the basis of the signal from sensor 164.
    If, on the other hand, no break is identified at all in step 402, so that the chopper blades 144 would have to be operated in a very dull, energy-consuming state, step 410 can be forcibly carried out at times and the forage harvester 10 take a forced grinding break.
    The grinding process of step 410 can be followed, in a manner known per se, for a procedure for adjusting the distance between shear bar 140 and the chopping knives 144 (step 414), as described above.
