Definitions
- the present invention relates to a harvester such as a combine.
- Harvesting machines include combine harvesters, corn harvesters and other crop harvesters.
- the combine includes a normal combine (also referred to as a full-pile input combine) in addition to the self-removing combine shown in the embodiment described later.
- the combine includes a crawler travel combine and a wheel travel combine.
- the harvesting machine is configured to temporarily store the crop harvested from the field while traveling in the harvest tank.
- the harvesting operation is performed on one or more fields by repeatedly storing the harvested product in the harvested tank and discharging it from the harvested tank.
- JP 2011-036193 A combine (a kind of harvester) disclosed in A (Patent Document 1) determines that the tilting posture of the traveling machine body is horizontal in the left-right direction and the front-rear direction by controlling the attitude of the combine using a hydraulic cylinder.
- a certain time for example, 10 seconds
- the mass (yield) of the grain in the grain tank is calculated on the assumption that preparation for precision measurement is complete.
- the combine according to Patent Document 2 includes a load cell that detects the weight of the grain tank, an inclination sensor that detects the inclination of the traveling body, and a yield measuring unit that calculates the grain weight based on the weight detection signal input from the load cell. I have. At that time, if the machine tilt by the tilt sensor is within the allowable range, a grain weight calculation command to the yield measuring means is output, and if the machine tilt by the tilt sensor is outside the allowable range, the grain weight calculation command is not output. .
- Patent Document 2 discloses a control for checking whether the aircraft tilt is within an allowable range when the calculated yield is output, and if the aircraft tilt is out of the allowable range, outputting a horizontal return command to the attitude control device. Yes.
- a load cell that measures the weight of a contained object together with the containing container, an error may occur in the measured result of the contained weight due to aging of the containing container or aging deformation of the mounting portion of the load cell.
- zero point adjustment as disclosed in JP 2009-264703 A Patent Document 3 is effective.
- the load cell in Patent Document 3 measures the weight of a drying device in a drying facility, and is provided on the upper side of a sheet metal frame member fixed to a floor surface of a building. For this reason, unlike the load cell provided in the combine that can be changed in posture disclosed in Patent Document 2, the load cell always maintains a horizontal posture, and the zero point adjustment takes into account the inclination of the posture. There is no need.
- JP 2013-118856 A (patent) as a combine to measure the quality of grain when harvesting and threshing grains from a farm while traveling and storing the obtained grain in a grain tank Some are described in Reference 4).
- the receiving holding part which creates the grain storage space which temporarily stores the grain sent to the grain tank is formed, and the internal quality of the grain stored in the grain storage space is It is measured by an optical internal quality measuring device.
- the bottom surface of the receiving and holding portion is formed by a swinging open / close bottom plate (shutter). The grains are temporarily stored in the closed state of the bottom plate, and the grains temporarily stored in the open state of the bottom plate are discharged.

- the presence or absence of a grain that detects whether or not the grain is present at the height level on the side wall of the grain tank at a position slightly below the lower end position of the open bottom plate A (grain level) sensor is provided. Every time the supply state detection sensor detects that a predetermined amount or more of the grain has been supplied to the receiving holder, a measurement process is performed by the internal quality measuring device. Then, after the bottom plate is switched to the open state and the grains are discharged, the bottom plate is returned to the closed state again, and the grains are stored.
- the tip of the bottom plate is finally buried in the grain, and the bottom plate cannot be switched from the open state to the closed state. For this reason, if the presence of a grain is detected by the grain presence / absence sensor, the measurement process is stopped.
- JP 2011-036193 A Japanese Laid-Open Patent Publication No. 2014-068543 (JP 2014-068543 A) JP 2009-264703 (JP-22009-264703 A) Japanese Unexamined Patent Publication No. 2013-118856 (JP 2013-118856 A)
- the means for solving the problem [1] is as follows.
- the harvester includes a harvest tank that temporarily stores a harvest that is harvested while traveling in a field, a measuring instrument that measures the amount of the harvest stored in the harvest tank, and a storage in the harvest tank. And an unloader device for discharging the harvested product to the outside.
- an instrument control unit that executes instrument setting processing for precision measurement that creates an instrument state that enables precision measurement by the instrument, and measurement by the instrument in precision measurement with the instrument setting process for precision measurement.
- a measurement control unit including a precision measurement execution unit to perform and a simple measurement execution unit to perform measurement by the measuring device by simple measurement without the precision measurement device setting process.
- an operation command processing unit that outputs a precision measurement command for instructing the precision measurement and a simple measurement command for instructing the simple measurement, and before a harvest discharge operation by the unloader device, Also provided is a measurement result recording unit for rewriting a simple measurement result based on the preceding simple measurement command with a precise measurement result based on the subsequent precise measurement command.
- the measurement control unit that controls the measurement of the amount of stored harvest using a measuring instrument has a precision measurement execution unit and a simple measurement execution unit.
- the stored harvest amount (yield) can be measured by a desired measurement method by giving the measurement control unit a simple measurement command.
- an instrument state for example, a stationary state of a vehicle body
- the measurement of the amount of harvest (also referred to as yield) stored in the harvest tank is normally performed before the harvest discharge operation by the unloader device.
- the precise measurement can be performed by giving a precise measurement command.
- the measurement result of the previous simple measurement is rewritten with the measurement result of the subsequent precise measurement. Even if both simple measurement and precision measurement are performed, it is advantageous because the measurement result of the precision measurement is recorded in the collection of the measurement result performed after the harvesting operation.
- the artificial operation device used by the driver (operator) to select either precision measurement or simple measurement
- a separate switch button or dial
- the artificial operation device includes a simple measurement switch for sending a signal for simple measurement command output to the operation command processing unit, and a precision measurement command output.
- a precision measurement switch for sending signals. In this configuration, the operator can clearly distinguish between precision measurement and precision measurement, thereby reducing selection errors.
- the simple measurement switch is also used as the start switch of the unloader device, for example, for simple measurement command output by multiple operations of the start switch.
- a signal is sent out, and a signal requesting activation of the unloader device is sent out by a single operation of the activation switch.
- the harvesting machine body in the precision measurement device setting process, is shifted to a horizontal posture, the power to the harvesting work device is cut off, and the unloading work device is fixed at the storage position. Any or all are performed.
- the harvest tank becomes a stable posture suitable for measurement by shifting the harvester vehicle body to the horizontal posture.
- the transmission of vibrations to the harvester tank and the measuring device is avoided by cutting off the power to the harvesting equipment.
- Stabilization of the measurement can be obtained by stabilizing the center of gravity of the vehicle body by fixing the unloading work device at the storage position. Thereby, measurement reliability of precision measurement is improved.
- a conversion table is required to derive the yield from the measured value.
- the conversion table differs depending on the type of harvest, or when identification data for identifying the type of harvest is added as a yield attribute value, it is necessary to reliably identify the harvest being harvested. There is. Since such a harvest varies depending on the season and year, the correct information has been registered in the management center recently. For this reason, in one preferred embodiment, a conversion table for deriving the yield, which is the amount of the crop stored in the crop tank, from the measurement value by the measuring instrument is sent from the management center through a data communication line. It is built on the data that comes. At that time, by providing the management center with identification information of the field to be harvested, appropriate data is sent from the management center to the control unit of the harvester.
- the unit yield which is the amount of the crop stored in the crop tank, calculated from the measurement result of the measuring instrument
- the integrated yield which is the integration of the unit yield
- the means for solving the problem [2] is as follows.
- the combine is a traveling machine body, a posture changing mechanism that changes the posture of the traveling machine body, a grain tank that is mounted on the traveling machine body and that stores the grain that has been conveyed from the threshing device, and the grain tank
- An unloader device that discharges the grain stored in the grain tank from the bottom to the outside, a load cell that measures the weight of the grain tank, and a grain that is stored in the grain tank based on the measurement result of the load cell
- a yield measuring unit that measures grain yield, a zero point adjusting unit that performs a zero point adjusting process of the yield measuring unit, and the posture changing mechanism that controls the posture changing mechanism at the start of the zero point adjusting process by the zero point adjusting unit
- a horizontal attitude control unit that sets the traveling machine body to a horizontal attitude.
- the horizontal control using the posture changing mechanism is first performed at the start of the zero point adjustment process, and the traveling aircraft is Becomes horizontal. This avoids the inconvenience that the zero point adjustment process including the error is performed while the traveling body is in the inclined posture, and the subsequent yield measurement is performed based on the zero point adjustment including the error.
- the unloader device includes a bottom screw provided at the bottom of the grain tank, a vertical feed screw conveyor that conveys the grain carried out by the bottom screw upward, and the vertical screw conveyor. It consists of a transverse feed screw conveyor that can swing in the vertical direction with respect to the feed screw conveyor, is equipped with a holding device that fixes the transverse feed screw conveyor at a home position, and starts zero point adjustment processing by the zero point adjustment unit
- the transverse screw conveyor is configured to be fixed by the holding device at the home position. In order to discharge the grain stored in the grain tank to the outside, when the unloader device as described above is mounted on the combine, the transverse feed screw conveyor is fixed by the holding device at the home position where it is the most stable position Otherwise, the traveling vehicle body may become unstable. In such a state, the zero point adjustment is likely to be inaccurate. This problem can be solved by automatically fixing the transverse feed screw conveyor at the home position at the start of the zero point adjustment process.
- the transverse screw conveyor is not fixed at the home position, the grain tank may be subjected to an unbalanced load that prevents accurate measurement.
- the transverse feed screw conveyor is configured to be able to swing up and down, and since it is necessary to bring a grain discharge point to a position away from the traveling machine body, it is long and heavy. Therefore, it is convenient to use the gravity due to the weight to fix the transverse screw conveyor by the holding device. For this reason, in one of the preferred embodiments, the transverse screw conveyor is vertically swung by hydraulic pressure, and the fixing by the holding device is performed by gravity insertion with the hydraulic pressure released. This configuration has the advantage that the structure of the holding device is simplified because the weight of the transverse feed screw conveyor is used for final fixing.
- a transverse feed screw conveyor and a holding device are preferably formed with a weight-like convex portion and a concave portion corresponding to the convex portion.
- the transverse feed conveyor is temporarily set. After swinging upward with hydraulic pressure, it is fixed to the holding device by a gravity insertion method with the hydraulic pressure released. This ensures that the lateral feed screw conveyor is in a stable position before the actual zero point adjustment is performed.
- the horizontal posture control unit controls the posture changing mechanism after the zero point adjustment processing is completed, so that the traveling aircraft body is set to a lower limit posture with the lowest ground height.
- the posture changing mechanism controls the farm scene and the traveling machine body to be horizontal.
- the lower limit posture where the ground height of the traveling machine body is the lowest is suitable as the reference departure posture.
- the traveling vehicle body since the traveling vehicle body always assumes the lower limit posture after the zero point adjustment process is completed, the driver can feel the completion of the zero point adjustment process.
- the zero point adjustment described above is performed in a measurement environment optimal for adjustment at the time of shipment from the factory.
- the measurement environment for zero point adjustment performed after collection is often inferior to the measurement environment for zero point adjustment at the time of shipment from the factory. For this reason, the zero point adjustment performed after collection may not be successful.
- the zero point adjustment process includes a basic zero point adjustment process performed at the time of factory shipment and a temporary zero point adjustment process performed after the factory shipment, and the temporary zero point adjustment process.
- the basic zero point adjustment parameter calculated by the basic zero point adjustment process is set instead of the temporary zero point adjustment parameter calculated by the above. At that time, the basic zero adjustment parameter is more important than the temporary zero adjustment parameter.
- the basic zero adjustment parameter is recorded in a memory before being replaced by the temporary zero adjustment parameter, and the basic zero adjustment parameter is reset when the temporary zero adjustment parameter is reset. Point adjustment parameters are reset.
- the means for solving the problem [3] is as follows.
- the combine includes a grain tank that stores the grain that has been conveyed from the threshing device, and a grain discharge device that discharges the grain stored in the grain tank from the bottom of the grain tank to the outside.
- a cylindrical formed body is provided in the grain tank.
- the cylindrical formed body forms a grain path, and the grain path takes in a part of the grain conveyed from the threshing device and the grain taken in from the intake At the bottom of the grain tank.
- route is provided, and the storage shutter is provided in the said temporary storage part.
- the storage shutter has a closed storage position that is in a lateral orientation for storing the grains taken in from the intake port in the temporary storage unit, and a downward direction for discharging the stored grains from the temporary storage unit.
- the position can be changed to the open position for discharge which becomes the posture.
- the shutter lower distance which is a distance between the lower end of the storage shutter in the downward posture and the upper surface of the grain stored in the kernel tank in the downward posture, has reached a predetermined value.
- a grain level detector to detect, and a quality measuring unit to detect the quality of the grain stored in the temporary storage unit, and further controls the position changing operation of the storage shutter and detects the grain level.
- a shutter control unit for stopping the position changing operation of the storage shutter based on a detection signal of the storage device.
- the grain level detector that detects the upper surface level of the grain that hinders the operation of the storage shutter is provided in the grain path. That is, since the grain level detector is disposed inside the tubular formed body, the tubular formed body functions as a protective cover. As a result, the grain level detector is not easily affected by the grains that flow while flying from the inlet.
- the cylindrical formed body has a first wall facing the center side of the grain tank and a second wall facing the wall body of the grain tank, and the storage shutter Is a rocking shutter that rocks around a rocking shaft supported by the first wall, and the grain level detector is provided on the first wall. If the lower end of the storage shutter enters the grain stored in the grain tank when the storage shutter is in the release open position in the downward position, the operation of the storage shutter stops. For this reason, it is important to detect the upper surface level of the grain in the vicinity of the lower end of the storage shutter in the downward posture. In this configuration, the lower end of the downwardly facing storage shutter approaches the first wall, so that the upper surface level of the grain near the lower end can be accurately detected by the grain level detector provided on the first wall.
- the grain level detector has a flat detection surface, and the grain level detector is arranged such that the detection surface and the first wall are flush with each other. Yes. With this configuration, since the grain level detector does not protrude into the grain path, it is avoided that the grain falling through the grain path is damaged by the grain level detector.
- a second grain level detector for detecting that the shutter lower distance has reached a predetermined value different from the predetermined value is disposed in the grain path.
- the second kernel level detector detects the upper surface level of the same kernel as the first kernel level detector (reaching of the shutter lower distance). If the predetermined value serving as the detection reference is the same between the two grain level detectors), it is also effective as a countermeasure against a failure when one of them fails.
- the upper surface level of the kernel detected by the first kernel level detector and the second kernel level detector is made different (the predetermined value serving as the arrival detection reference for the distance below the shutter is two kernels).
- the detection result can be divided into a warning alarm and an emergency alarm.
- this second grain level detector is also included in the grain path. It is preferable to arrange
- the signals from the two kernel level detectors have entered the kernel path.
- the degree of inclination of the upper surface level of the grain can be estimated.
- the storage shutter can be driven and the quality of the grain can be measured until the grain enters the swinging locus of the storage shutter.
- the means for solving the problem [4] is as follows.
- the combine includes a grain tank that stores the grain that has been conveyed from the threshing apparatus, a grain discharge apparatus that discharges the grain stored in the grain tank from the bottom of the grain tank, and the grain An upper intake port that is provided in the grain tank and takes in a part of the grain conveyed from the threshing device, and a lower discharge port that discharges the grain taken in from the intake port to the grain tank And a temporary storage part located in the middle of the grain path, and a closed storage for storing the grain taken in from the intake port in the temporary storage part.
- a storage shutter that can be repositioned to a position and an open position for release that releases the stored grain from the temporary storage unit, and the storage is completed when the amount of kernel stored in the temporary storage unit reaches a predetermined amount
- a reservoir detector that outputs a signal and A quality measuring unit for detecting the quality of the grain stored in the temporary storage unit, a shutter control unit for controlling the position changing operation of the storage shutter, and a yield of the grain stored in the grain tank are measured. Based on the yield measuring device and the storage amount detector does not output the storage completion signal even if the storage amount in the temporary storage unit estimated based on the measurement result of the yield measuring device exceeds the predetermined amount
- a failure determination unit that determines failure of the storage amount detector.
- the storage amount detector is stored when the grain stored in the temporary storage unit reaches a predetermined amount that is suitable for detecting the quality of the grain by the quality measurement unit, for example. Outputs a completion signal.
- the failure determination unit estimates the amount of grains stored in the temporary storage unit, that is, the storage amount, from the measurement result of the yield measuring device, so that the estimated storage amount is If the storage amount detector does not output the storage completion signal even though it exceeds the predetermined amount that is set in advance, it can be considered that the storage amount detector has failed.
- a shutter position detector that detects a change position of the storage shutter
- the failure determination unit includes a measurement result of the yield measuring device over time and the shutter position detector. Based on the detection result, a failure of the storage amount detector is determined.
- the timing at which the storage shutter is in the storage closed position which is the timing at which the grains start to be stored in the temporary storage unit, is accurately detected by the shutter position detector. Thereby, quicker and more accurate determination of the storage amount detector failure is realized.
- the shutter position detector detects a change in the position of the storage shutter even though a control signal instructing a position change operation of the storage shutter is output from the shutter control unit.
- the failure determination unit determines whether or not the storage shutter has failed based on not being performed. Therefore, it is possible to cope with a problem that an appropriate signal is not output from the storage amount detector due to a malfunction of the storage shutter. For example, since the storage shutter cannot be changed to the storage closed position, it is possible to distinguish between a failure of the storage shutter or a failure of the storage amount detector with respect to a phenomenon in which grains are not stored in the temporary storage unit.
- the failure determination unit is configured to use the storage amount detector based on an increase from the yield when the storage shutter is changed to the storage closed position reaching a predetermined amount. Determine the failure. Since the increase amount of the grain flowing into the grain tank can be calculated from the measurement result of the yield measurement, if this increase amount is the amount that the storage completion signal must be output from the storage amount detector, It can be considered that the storage volume detector has failed. In addition, since the ratio of passing through the grain path among the grains released from the inflow port can be determined in advance, the relationship between the amount of increase in grains and the storage amount in the temporary storage unit is functionalized or tabulated. can do.
- the amount of grain increase in the grain tank after the storage shutter is closed exceeds the value corresponding to the predetermined amount for which the storage completion signal is output by the storage amount detector, If the storage completion signal is not output, it can be determined that the storage amount detector has failed.
- the storage amount detector continues to output the storage completion signal even after the storage shutter is changed from the storage closed position to the release open position.
- the failure determination unit determines a failure of the storage amount detector. In other words, the storage amount detector continues to output the storage completion signal even though the storage shutter is changed from the storage closed position to the release open position, and the grain should have been discharged from the temporary storage section. Even in this case, the failure determination unit can determine that the storage amount detector is defective.

Abstract
Description
このような収穫機では、収穫物の収穫物タンクへの収納と収穫物タンクからの排出を繰り返して、1つ以上の圃場に対する収穫作業を行う。JP 2011-036193 A(特許文献1)で開示されたコンバイン(収穫機の一種)では、油圧シリンダを用いたコンバインの姿勢制御によって走行機体の傾斜姿勢が左右方向及び前後方向に関して水平であると判断されて一定時間(例えば10秒が)経過することで、精密測定のための準備が整ったとして、穀物タンク内の穀粒の質量(収量)が算出される。このようなコンバインでは、穀物タンク内の穀粒の質量を正確に測ることができるが、精密測定のための準備に時間がかかる。このため、精密測定のための準備なしでの簡易的な測定も行いたいという要望がある。
収容物の重量をその収容容器とともに測定するロードセルでは、収容容器の経年変化やロードセルの取付部の経年変形などによって、収容物重量の測定結果に誤差が生じてくる場合がある。このような誤差を解消するためには、JP 2009-264703 A(特許文献3)で開示されているようなゼロ点調整が有効である。この特許文献3におけるロードセルは、乾燥設備における乾燥装置の重量を測定するものであり、建屋の床面に固定された板金製のフレーム部材の上側に設けられている。このため、このロードセルは、特許文献2に開示されている姿勢変更可能なコンバインに設けられたロードセルとは異なり、常時水平姿勢は維持されており、ゼロ点調整では、姿勢の傾きなどを考慮する必要がない。
このコンバインでは、穀粒タンクに送り込まれてきた穀粒を一時的に貯留する穀粒貯留空間を作り出す受け止め保持部が形成されており、穀粒貯留空間に貯留している穀粒の内部品質が光学式の内部品質計測装置によって計測される。この受け止め保持部の底面は、揺動開閉式の底板(シャッタ)によって形成されている。底板の閉状態で穀粒が一時的に貯留され、底板の開状態で一時的に貯留された穀粒が排出される。受け止め保持部の内部の上端部には、穀粒が所定量以上貯留されたことを検出する供給(貯留)状態検出センサが備えられている。受け止め保持部の下方領域には、開状態の底板の下端位置よりも少し下方の位置で、穀粒タンクの側壁に、その高さレベルに穀粒が存在するか否かを検出する穀粒存否(穀粒レベル)センサが備えられている。受け止め保持部に穀粒が所定量以上供給されたことが供給状態検出センサにて検出される毎に、内部品質計測装置による計測処理が行われる。その後、底板が開状態に切り換えられ穀粒が排出された後、底板は再び閉状態に戻され、穀粒が貯留されていく。穀粒タンクでの穀粒量が増加してくると、ついには、底板の先端が穀粒に埋まり、底板を開状態から閉状態に切り換えることができなくなってしまう。このため、穀粒存否センサにて穀粒の存在が検出されると、計測処理は中止される。
上記実情に鑑み、ユーザのその時の要望に合わせて、収穫物タンクに貯留された収穫物の量を精密測定または簡易測定のいずれかでスムーズに行うことができる収穫機が望まれる。
上記実情に鑑み、姿勢変更が行われる機体に搭載された穀粒タンクの重量を計測するロードセルのゼロ点調整を効率よく行うことができるコンバインが望まれる。
特許文献4では、静電容量型の近接センサで構成された穀粒レベルセンサが穀粒タンクの側壁に設けられているので、穀粒タンクの流入口から飛翔しながら流れ込んでくる穀粒の影響を受けて、誤検出する可能性がある。このため、穀粒レベルセンサが流入口から飛翔しながら流れ込んでくる穀粒の影響を受けにくい構造が要望されている。
特許文献4では、品質計測に適切な所定量以上の穀粒が受け止め保持部に貯留されたかどうかは貯留状態検出センサによって検出されるので、この貯留状態検出センサが故障した場合、品質計測ができなくなる。このため、貯留状態検出センサの故障を迅速かつ確実に検知できる技術が要望されている。
収穫機は、圃場を走行しながら収穫された収穫物を一時的に貯留する収穫物タンクと、前記収穫物タンクに貯留された収穫物の量を測定する測定器と、前記収穫物タンクに貯留された収穫物を外部に排出するアンローダ装置とを備えている。制御系として、前記測定器による精密測定を可能にする機器状態を作り出す精密測定用機器設定処理を実行する機器制御部と、前記精密測定用機器設定処理をともなう精密測定で前記測定器による測定を行う精密測定実行部及び前記精密測定用機器設定処理を伴わない簡易測定で前記測定器による測定を行う簡易測定実行部とを有する測定制御部とが備えられている。さらに、人為操作デバイスに対する操作に応じて、前記精密測定を指令する精密測定指令及び前記簡易測定を指令する簡易測定指令を出力する操作指令処理部と、前記アンローダ装置による収穫物排出作業前において、先行した簡易測定指令に基づく簡易測定結果の記録を、後続の精密測定指令に基づく精密測定結果で書き換える測定結果記録部も備えている。
これにより、精密測定の測定信頼性が向上する。
コンバインは、走行機体と、前記走行機体の姿勢を変更する姿勢変更機構と、前記走行機体に搭載されるとともに脱穀装置から搬送されてきた穀粒を貯留する穀粒タンクと、前記穀粒タンクの底部から前記穀粒タンクに貯留された穀粒を外部に排出するアンローダ装置と、前記穀粒タンクの重量を測定するロードセルと、前記ロードセルの測定結果に基づいて前記穀粒タンクに貯留された穀粒の収量を計測する収量計測部と、前記収量計測部のゼロ点調整処理を行うゼロ点調整部と、前記ゼロ点調整部によるゼロ点調整処理の開始時に前記姿勢変更機構を制御して前記走行機体を水平姿勢にする水平姿勢制御部と、を備えている。
コンバインには、脱穀装置から搬送されてきた穀粒を貯留する穀粒タンクと、前記穀粒タンクの底部から前記穀粒タンクに貯留された穀粒を外部に排出する穀粒排出装置とが備えられ、前記穀粒タンク内には筒状形成体が設けられている。前記筒状形成体は穀粒経路を形成しており、前記穀粒経路は前記脱穀装置から搬送されてきた穀粒の一部を取り込む上方の取込口及び前記取込口から取り込んだ穀粒を前記穀粒タンクに排出する下方の排出口を有する。前記穀粒経路の途中に位置する一時貯留部が備えられ、前記一時貯留部に貯留シャッタが設けられている。前記貯留シャッタは、前記取込口から取り込んだ穀粒を前記一時貯留部に貯留するために横向き姿勢となる貯留用閉位置と、貯留された穀粒を前記一時貯留部から放出するために下向き姿勢となる放出用開位置とに位置変更可能である。前記穀粒経路内に配置され、前記下向き姿勢での前記貯留シャッタの下端と前記穀粒タンクに貯留された穀粒の上面との間の距離であるシャッタ下方距離が所定値に達したことを検出する穀粒レベル検出器と、前記一時貯留部に貯留された穀粒の品質を検出する品質計測部とが備えられ、さらに、前記貯留シャッタの位置変更動作を制御するとともに前記穀粒レベル検出器の検出信号に基づいて前記貯留シャッタの位置変更動作を停止するシャッタ制御部が備えられている。
このように2台の穀粒レベル検出器も設ける場合、例えば、第2の穀粒レベル検出器を第1の穀粒レベル検出器と同じ穀粒の上面レベルを検出する(シャッタ下方距離の到達検出基準となる所定値が、2台の穀粒レベル検出器の間で同じである)ようにすれば、一方が故障した際の故障対策としても有効である。
一方、第1の穀粒レベル検出器と第2の穀粒レベル検出器とによって検出される穀粒の上面レベルを相違させる(シャッタ下方距離の到達検出基準となる所定値が、2台の穀粒レベル検出器の間で相違する)と、その検出結果を注意警報用と緊急警報用に分けて利用することができる。
いずれの構成にあっても、先に述べた穀粒レベル検出器(第1の穀粒レベル検出器)と同じ利点を得るためには、この第2の穀粒レベル検出器も穀粒経路内に配置されることが好ましい。
コンバインは、脱穀装置から搬送されてきた穀粒を貯留する穀粒タンクと、前記穀粒タンクの底部から前記穀粒タンクに貯留された穀粒を外部に排出する穀粒排出装置と、前記穀粒タンク内に設けられるとともに、前記脱穀装置から搬送されてきた穀粒の一部を取り込む上方の取込口及び前記取込口から取り込んだ穀粒を前記穀粒タンクに排出する下方の排出口を有する穀粒経路と、前記穀粒経路の途中に位置する一時貯留部と、前記一時貯留部に設けられるとともに、前記取込口から取り込んだ穀粒を前記一時貯留部に貯留する貯留用閉位置と、貯留された穀粒を前記一時貯留部から放出する放出用開位置とに位置変更可能な貯留シャッタと、前記一時貯留部に貯留される穀粒が所定量に達した際に貯留完了信号を出力する貯留量検出器と、前記一時貯留部に貯留された穀粒の品質を検出する品質計測部と、前記貯留シャッタの位置変更動作を制御するシャッタ制御部と、前記穀粒タンクに貯留される穀粒の収量を測定する収量測定器と、前記収量測定器の測定結果に基づいて推定される前記一時貯留部における貯留量が前記所定量を超えても前記貯留量検出器が前記貯留完了信号を出力しないことに基づいて前記貯留量検出器の故障を判定する故障判定部とを備えている。
