Description

本発明は、コンバインの穀粒貯留装置に係るものである。 The present invention relates to a combine grain storage device.

従来より、コンバインは、走行装置の上方に脱穀装置と穀粒貯留装置とを並設し、脱穀装置の前側に刈取装置を設けて機体を構成しており、穀粒貯留装置の底面は、該穀粒貯留装置の下部に配置した螺旋搬送装置に向けて傾斜させて設けられている。 Conventionally, a combine has a threshing device and a grain storage device arranged in parallel above a traveling device, and a cutting device is provided on the front side of the threshing device to form a machine body. It is inclined and provided toward the spiral conveying device arranged at the lower part of the grain storage device.

そして、コンバイン作業においては、刈取脱穀作業中に、収穫した穀粒を機体に搭載する穀粒貯留装置に一時貯留し、この穀粒貯留装置が満杯になると、穀粒貯留装置に設けた穀粒排出装置を駆動して運搬車に穀粒を排出する。 In the combine work, during harvesting and threshing work, the harvested grain is temporarily stored in the grain storage device mounted on the machine body, and when this grain storage device is full, the grain provided in the grain storage device The discharging device is driven to discharge the grains to the transport vehicle.

この際、刈取穀稈が濡れており、収穫した穀粒も濡れている場合には、穀粒貯留装置の底面に穀粒が付着して下部の螺旋搬送装置に流下しにくく、穀粒の排出が中断したり、穀粒の排出速度が低下したりして、穀粒排出作業を能率良く行うことができない。 At this time, if the harvested cereal is wet and the harvested grain is also wet, the grain adheres to the bottom of the grain storage device and is difficult to flow down to the lower spiral conveying device, and the grain is discharged. Is interrupted, or the grain discharge rate is reduced, and the grain discharge work cannot be performed efficiently.

そこで、このような問題を解決する技術として、穀粒貯留装置の底部外側に送風機を設け、送風によって穀粒を乾燥させて流下を促進しようとするものがある（例えば、特許文献１参照。）。 Therefore, as a technique for solving such a problem, there is a technique in which a blower is provided outside the bottom of the grain storage device and the grain is dried by blowing to promote the flow down (see, for example, Patent Document 1). .

また、穀粒貯留装置の内部に送風パイプを配置し、この送風パイプからエンジン冷却後の温風を吹き出して、貯留穀粒を乾燥させようとするものがある。（例えば、特許文献２参照。）。
実開平４−２８０４２号公報（実用新案登録請求の範囲の項、第１図，第２図）実開昭６２−１６９９４１号（第７図，第８図） Moreover, there exists a thing which arrange | positions a ventilation pipe inside a grain storage apparatus, blows out the warm air after engine cooling from this ventilation pipe, and dries a stored grain. (For example, refer to Patent Document 2).
Japanese Utility Model Laid-Open No. 4-28042 (utility model registration claim section, FIGS. 1 and 2) Japanese Utility Model Publication Sho 62-169941 (Figs. 7 and 8)

前述のように、穀粒貯留装置の底部外側に送風機を設け、送風によって穀粒を乾燥させて流下を促進しようとした場合、穀粒貯留装置の底部を目抜き板状に構成して通風可能としなければならない。しかしながら、この目抜き孔の目合いは、穀粒が漏下しない程度の大きさにしかできず、また、穀粒の貯留重量に耐え得る強度を確保するために、ある程度の間隔をおいて穿孔せねばならいため、通風面積が小さく制約され、穀粒を充分に乾燥させられるだけの送風を行うことができない。また、このように穀粒貯留装置の底部を目抜き状に形成すると、この底部を穀粒が流下する際に摩擦抵抗が大きくなり、穀粒の流下の妨げとなる。 As mentioned above, when a blower is installed outside the bottom of the grain storage device and the grain is dried by blowing to promote flow down, the bottom of the grain storage device can be configured as a hollow plate and ventilated. And shall be. However, the size of the opening holes can only be so large that the grains do not leak out, and in order to ensure the strength that can withstand the stored weight of the grains, the openings are perforated at a certain interval. Therefore, the ventilation area is restricted to be small, and it is not possible to blow air enough to dry the grains sufficiently. In addition, when the bottom of the grain storage device is formed in a hollow shape in this way, frictional resistance increases when the grain flows down the bottom, and hinders the flow of the grain.

従って、穀粒貯留装置の底部外側に送風機を設け、送風によって穀粒を乾燥させて流下を促進しようとする技術では、穀粒が濡れている場合に、穀粒貯留装置の底面に穀粒が付着して下部の螺旋搬送装置に流下しにくく、穀粒の排出が中断したり、穀粒の排出速度が低下したりして、穀粒排出作業を能率良く行うことができない問題が残る。 Therefore, in the technology of providing a blower outside the bottom of the grain storage device and promoting the flow down by drying the kernel by blowing air, when the grain is wet, the grain is on the bottom of the grain storage device. It is difficult to flow down to the lower spiral conveying device, and the grain discharge operation is interrupted or the grain discharge speed is lowered, so that the grain discharge operation cannot be performed efficiently.

図４を基に、前記ヒ−タ−３２への通電回路について説明するに、ＣＰＵを有するコントロ−ラ３４の入力側に、水分計３５とオ−ガ排出クラッチ検出センサ３６とを接続する一方、前記コントロ−ラ３４の出力側ぶ、ヒ−タ−制御スイッチ３７を接続する。前記ヒ−タ−制御スイッチ３７は、バッテリ−３８からヒ−タ−３２への通電を入り切りするリレ−３９を作動させるものである。また、図５に示すように、前記螺旋搬送装置２８から揚穀部２９内の揚穀螺旋および穀粒排出オ−ガ３０内の排出螺旋を連動して駆動する排出クラッチ４０を構成すると共に、該排出クラッチ４０を入り切り操作する排出クラッチ操作レバ−４１を設け、該排出クラッチ操作レバ−４１を穀粒排出クラッチ入り側に操作した際に前記オ−ガ排出クラッチ検出センサ３６がＯＮするように構成する。 Referring to FIG. 4, the energization circuit to the heater 32 will be described. On the input side of a controller 34 having a CPU, a moisture meter 35 and an oga discharge clutch detection sensor 36 are connected. The heater control switch 37 connected to the output side of the controller 34 is connected. The heater control switch 37 operates a relay 39 that turns on / off the power supply from the battery 38 to the heater 32. Moreover, as shown in FIG. 5, while constituting the discharge | emission clutch 40 which interlock | cooperates and drives the raising helix in the cerealing part 29 and the discharge helix in the grain discharge | release oger 30 from the said helical conveyance apparatus 28, A discharge clutch operation lever 41 for turning on and off the discharge clutch 40 is provided so that the auger discharge clutch detection sensor 36 is turned on when the discharge clutch operation lever 41 is operated to the side of the grain discharge clutch. Constitute.

以上の構成により、圃場におけるコンバイン作業は、走行装置２を駆動して前進しながら刈取装置５によって植立穀稈を刈り取り、刈取穀稈を脱穀装置３に供給して脱穀処理し、収穫された穀粒を穀粒貯留装置４に一時貯留すると共に、脱穀後の排藁を排藁処理装置に投入して細断して圃場面上へ放出する。 With the above configuration, the combine work in the field was harvested by driving the traveling device 2 and cutting the planted cereal by the reaping device 5 while moving forward, supplying the reaped cereal to the threshing device 3, and harvesting. The grain is temporarily stored in the grain storage device 4, and after the threshing, the waste is thrown into the waste processing device and shredded and released onto the field scene.

このような刈取脱穀作業中に穀粒貯留装置４が満杯になった場合に、穀粒貯留装置４内の穀粒を外部へ排出する作業を行う。この際、穀粒排出オ−ガ旋回操作レバ−と穀粒排出オ−ガ伸縮操作スイッチとを操作して穀粒排出オ−ガ３０先端部の排出口を適正な排出作業位置に合わせた後、排出クラッチ操作レバ−４１を入り操作する。これによってオ−ガ排出クラッチ検出センサ３６がＯＮしてコントロ−ラ３４からヒ−タ−制御スイッチ３７へ出力がなされ、該ヒ−タ−制御スイッチ３７によってリレ−３９の接点がＯＮしてバッテリ−３８からヒ−タ−３２へ通電され、該ヒ−タ−３２が発熱する。これによって、ヒ−タ−３２を取り付けた穀粒貯留装置４の底面３１の温度が上昇し、該傾斜した底面３１上の穀粒の少なくとも表面がこの熱によって乾燥しながら下部の螺旋搬送装置２８へ向けて円滑に流下し、該螺旋搬送装置２８に続く揚穀部２９および穀粒排出オ−ガ３０によって外部へ排出される。 When the grain storage device 4 becomes full during such reaping and threshing work, the operation of discharging the grain in the grain storage device 4 to the outside is performed. At this time, after operating the grain discharge agar turning operation lever and the grain discharge agar telescopic operation switch, the outlet of the grain discharge agar 30 is adjusted to an appropriate discharge work position. Then, the discharge clutch operation lever 41 is entered and operated. As a result, the oger discharge clutch detection sensor 36 is turned ON and an output is made from the controller 34 to the heater control switch 37. The contact of the relay 39 is turned ON by the heater control switch 37, and the battery is turned on. -38 is energized to the heater 32, and the heater 32 generates heat. As a result, the temperature of the bottom surface 31 of the grain storage device 4 to which the heater 32 is attached rises, and at least the surface of the grain on the inclined bottom surface 31 is dried by this heat while the lower spiral conveying device 28. And then discharged to the outside by the cerealing part 29 and the grain discharging agar 30 following the spiral conveying device 28.

このように、通電によって発熱するヒ−タ−３２によって穀粒貯留装置４の底面３１の温度を上昇させることにより、貯留穀粒が濡れている場合でも、この穀粒を乾燥させながら下部の螺旋搬送装置２８に円滑に流下させることができ、穀粒排出作業を能率良く行うことができる。 In this way, by raising the temperature of the bottom surface 31 of the grain storage device 4 by the heater 32 that generates heat by energization, even when the stored grain is wet, the lower spiral is used while drying the grain. The conveying device 28 can be made to flow smoothly, and the grain discharging operation can be performed efficiently.

尚、穀粒排出を終了して排出クラッチ操作レバ−４１を切り操作すると、オ−ガ排出クラッチ検出センサ３６がＯＦＦしてコントロ−ラ３４からヒ−タ−制御スイッチ３７への出力が停止し、リレ−３９の接点がＯＦＦしてバッテリ−３８からヒ−タ−３２への通電が断たれる。このように、穀粒排出作業時以外はバッテリ−３８の電力を消費しないので効率的である。 When the grain discharge is finished and the discharge clutch operation lever 41 is turned off, the auger discharge clutch detection sensor 36 is turned OFF and the output from the controller 34 to the heater control switch 37 is stopped. Then, the contact of the relay 39 is turned OFF, and the power supply from the battery 38 to the heater 32 is cut off. Thus, the power of the battery 38 is not consumed except during the grain discharging operation, which is efficient.

尚、前記排出クラッチ操作レバ−４１およびオ−ガ排出クラッチ検出センサ３６を、脱穀クラッチ操作レバ−および脱穀クラッチ検出センサに換え、脱穀クラッチ操作レバ−の入り操作によって脱穀クラッチ検出センサがＯＮしてコントロ−ラ３４からヒ−タ−制御スイッチ３７へ出力がなされ、該ヒ−タ−制御スイッチ３７によってリレ−３９の接点がＯＮしてバッテリ−３８からヒ−タ−３２へ通電されて該ヒ−タ−３２が発熱するように構成してもよい。 The draining clutch operation lever 41 and the auger discharging clutch detection sensor 36 are replaced with a threshing clutch operation lever and a threshing clutch detection sensor. An output is made from the controller 34 to the heater control switch 37, and the contact point of the relay 39 is turned on by the heater control switch 37 so that power is supplied from the battery 38 to the heater 32, and the heater 32 is turned on. -You may comprise so that the ter 32 may generate | occur | produce heat.

また、穀粒貯留装置４の底面３１上に水分計４２を設置し、該水分計４２を前記コントロ−ラ３４の入力側に追加接続して、該水分計４２が穀粒の設定値以上の水分含有状態（濡れ具合）を検出した場合に、コントロ−ラ３４からヒ−タ−制御スイッチ３７へ出力がなされ、該ヒ−タ−制御スイッチ３７によってリレ−３９の接点がＯＮしてバッテリ−３８からヒ−タ−３２へ通電され、該ヒ−タ−３２が発熱するように構成してもよい。 In addition, a moisture meter 42 is installed on the bottom surface 31 of the grain storage device 4, the moisture meter 42 is additionally connected to the input side of the controller 34, and the moisture meter 42 exceeds the set value of the grain. When the moisture content state (wetting condition) is detected, an output is made from the controller 34 to the heater control switch 37, and the contact of the relay 39 is turned on by the heater control switch 37, and the battery The heater 32 may be energized from the heater 38 so that the heater 32 generates heat.

このように構成することにより、貯留穀粒の水分含有量が多い場合（濡れ具合が高い場合）にのみヒ−タ−３２によって穀粒貯留装置４の底面３１を加熱できるので、貯留穀粒の水分含有量が少ない場合にはバッテリ−３８の電力を消費せず、効率的である。 By comprising in this way, since the bottom face 31 of the grain storage apparatus 4 can be heated by the heater 32 only when the moisture content of the stored grain is high (when the wetness is high), the stored grain When the water content is low, the power of the battery 38 is not consumed, which is efficient.

また、ヒ−タ−３２へ至る電気ヘ−ネス３３は、機体１に対して穀粒貯留装置４を回動自在に取り付ける縦軸の近傍に配索されているため、穀粒貯留装置４を縦軸中心に機体１の外側へ回動させても、この電気ハ−ネス３３が引っ張られたりすることが少なく、該電気ハ−ネス３３の損傷を防止することができる。 Moreover, since the electrical harness 33 leading to the heater 32 is routed in the vicinity of the vertical axis where the grain storage device 4 is rotatably attached to the machine body 1, the grain storage device 4 is The electrical harness 33 is hardly pulled even if it is rotated about the longitudinal axis to the outside of the machine body 1, and damage to the electrical harness 33 can be prevented.

図６〜図８に示すように、上記実施例１と同様の機体１構成をもつコンバインにおいて、穀粒貯留装置４の底面３１の下側外方に排気ガス流通室４３（加熱手段Ｓ）を形成し、該排気ガス流通室４３の前側に給気パイプ４４を連通させて設ける一方、排気ガス流通室４３の後側に排気パイプ４５を連通させて後方へ延長させて設け、エンジンＥの排気管４６を前記給気パイプ４４に連通させて設けてもよい。 As shown in FIGS. 6 to 8, in the combine having the same machine body 1 configuration as that of the first embodiment, an exhaust gas circulation chamber 43 (heating means S) is provided outside the bottom surface 31 of the grain storage device 4. The exhaust pipe 45 is formed and communicated to the front side of the exhaust gas circulation chamber 43, while the exhaust pipe 45 is communicated to the rear side of the exhaust gas circulation chamber 43 and extended rearward. A tube 46 may be provided in communication with the air supply pipe 44.

このように構成することにより、排気管４６から吹き出すエンジンＥの高温の排気ガスが、給気パイプ４４を通って排気ガス流通室４３に流入し、該排気ガス流通室４３から排気パイプ４５を通って外部へ排気されることとなる。この間に、排気ガスの流通によって排気ガス流通室４３の室温が上昇し、これによって穀粒貯留装置４の底面３１が加熱される。これによって、穀粒貯留装置４の底面３１の温度が上昇し、該傾斜した底面３１上の穀粒の少なくとも表面がこの熱によって乾燥しながら下部の螺旋搬送装置２８へ向けて円滑に流下し、該螺旋搬送装置２８に続く揚穀部２９および穀粒排出オ−ガ３０によって外部へ排出される。 With this configuration, the high-temperature exhaust gas of the engine E blown from the exhaust pipe 46 flows into the exhaust gas circulation chamber 43 through the supply pipe 44 and passes through the exhaust pipe 45 from the exhaust gas circulation chamber 43. Exhausted to the outside. During this time, the room temperature of the exhaust gas circulation chamber 43 rises due to the circulation of the exhaust gas, whereby the bottom surface 31 of the grain storage device 4 is heated. Thereby, the temperature of the bottom surface 31 of the grain storage device 4 rises, and at least the surface of the grain on the inclined bottom surface 31 flows smoothly toward the lower spiral conveying device 28 while being dried by this heat, It is discharged to the outside by the cerealing part 29 and the grain discharging agar 30 following the spiral conveying device 28.

このように、エンジンＥの排気ガスによって穀粒貯留装置４の底面３１の温度を上昇させることにより、貯留穀粒が濡れている場合でも、この穀粒を乾燥させながら下部の螺旋搬送装置２８に円滑に流下させることができ、穀粒排出作業を能率良く行うことができる。 In this way, by raising the temperature of the bottom surface 31 of the grain storage device 4 by the exhaust gas of the engine E, even when the stored grain is wet, the spiral conveying device 28 in the lower part is dried while the grain is dried. It can be made to flow smoothly and the grain discharging operation can be performed efficiently.

また、図９に示すように、穀粒貯留装置４を、底面３１と螺旋搬送装置２８と排気ガス流通室４３とを一体的に備えた鉄板製の下側貯留部４ａと、該下側貯留部４ａの上側に着脱自在の樹脂製の上側貯留部４ｂとから構成してもよい。このように構成することにより、貯留穀粒が濡れている場合でも、この穀粒を乾燥させながら下部の螺旋搬送装置２８に円滑に流下させることができ、穀粒排出作業を能率良く行うことができるものでありながら、樹脂製で軽量の上側貯留部４ｂを、機体１側に設置した鉄板製の下側貯留部４ａから簡単に取り外して、穀粒貯留装置４のメンテナンスを容易に行うことができる。 Further, as shown in FIG. 9, the grain storage device 4 includes an iron plate lower storage portion 4 a integrally provided with a bottom surface 31, a spiral conveyance device 28, and an exhaust gas circulation chamber 43, and the lower storage. You may comprise from the resin-made upper side storage part 4b on the upper side of the part 4a. By comprising in this way, even when the stored grain is wet, it is possible to smoothly flow down to the lower spiral conveying device 28 while drying the grain, and to efficiently perform the grain discharging operation. Although it is possible, maintenance of the grain storage device 4 can be easily performed by easily removing the lightweight upper storage portion 4b made of resin from the lower storage portion 4a made of iron plate installed on the body 1 side. it can.

尚、前記給気パイプ４４の前端部は、直径を大きくして拡開して設け、この内側に前記エンジンＥの排気管４６後端部を入り込ませ、これら給気パイプ４４の前端部の内周部と排気管４６後端部の外周部との間に所定の間隙を設けて連通させる。この構成により、エンジンＥの振動によって排気管４６が振動しても、該排気管４６と給気パイプ４４との接続状態が損なわれることがなく、また、エンジンＥの排気ガスが排気管４６から給気パイプ４４に流入する際に、エジェクタ−効果によって前記の間隙から外気が引き込まれることとなり、逆に排気ガスが外部へ漏れることがなくなる。 The front end portion of the air supply pipe 44 is provided with an enlarged diameter, and a rear end portion of the exhaust pipe 46 of the engine E is inserted inside the front end portion. A predetermined gap is provided between the peripheral portion and the outer peripheral portion of the rear end portion of the exhaust pipe 46 to communicate with each other. With this configuration, even if the exhaust pipe 46 vibrates due to the vibration of the engine E, the connection state between the exhaust pipe 46 and the air supply pipe 44 is not impaired, and the exhaust gas of the engine E flows from the exhaust pipe 46. When the air flows into the air supply pipe 44, the outside air is drawn from the gap due to the ejector effect, and the exhaust gas does not leak to the outside.

図１０〜図１２に示すように、前記実施例２における給気パイプ４４と排気パイプ４５とを連続する１本のパイプ４７によって構成してもよい。 As shown in FIGS. 10 to 12, the air supply pipe 44 and the exhaust pipe 45 in the second embodiment may be configured by a single continuous pipe 47.

これにより、パイプ４７内を排気ガスが流通することによって該パイプ４７が加熱され、この熱によって穀粒貯留装置４の底面３１の温度を上昇させて、貯留穀粒が濡れている場合でも、この穀粒を乾燥させながら下部の螺旋搬送装置２８に円滑に流下させることができ、穀粒排出作業を能率良く行うことができる。 Thereby, the pipe 47 is heated by the exhaust gas flowing through the pipe 47, and even when the stored grain is wet by raising the temperature of the bottom surface 31 of the grain storage device 4 by this heat. While drying the grain, it is possible to smoothly flow down to the lower spiral conveying device 28, and the grain discharging operation can be performed efficiently.

図１３、図１４に示すように、前記実施例３と同様の構成において、穀粒貯留装置４を縦軸Ｐを中心として機体１外側方向へ回動させられるように構成してもよい。この場合、エンジンＥの排気管４６とパイプ４７の前端部（給気パイプ４４）とを接続離脱自在とするために、排気管４６の後端部内側に半割れケ−ス４８ａを取り付ける一方、パイプ４７の前端部外側に半割れケ−ス４８ｂを取り付け、穀粒貯留装置４を機体１上の所定の作業位置に固定した状態では、前記半割れケ−ス４８ａと半割れケ−ス４８ｂとが接合されてケ−シングとなり、穀粒貯留装置４を機体１外側方向へ回動させる場合には、半割れケ−ス４８ｂが半割れケ−ス４８ａから分離される構成とする。尚、この半割れケ−スによる構成は、実施例１から５のいずれにも適用できるものである。 As shown in FIGS. 13 and 14, in the same configuration as in the third embodiment, the grain storage device 4 may be configured to be rotated in the outer direction of the body 1 around the vertical axis P. In this case, in order to connect and disconnect the exhaust pipe 46 of the engine E and the front end portion (air supply pipe 44) of the pipe 47, a half crack case 48a is attached to the inside of the rear end portion of the exhaust pipe 46, In a state where a half-cracked case 48b is attached to the outside of the front end portion of the pipe 47 and the grain storage device 4 is fixed at a predetermined work position on the machine body 1, the half-cracked case 48a and the half-cracked case 48b are used. When the grain storage device 4 is rotated in the outer direction of the machine body 1, the half-cracked case 48b is separated from the half-cracked case 48a. In addition, the structure by this half crack case is applicable to any of Example 1-5.

図１５、図１６に示すように、前記実施例３と同様の構成において、穀粒貯留装置４の底面３１の外側面に対して、パイプ４７を一体的に備えた鉄板製のカバ−４９を接続離脱自在に構成してもよい。このように構成することにより、貯留穀粒が濡れている場合でも、この穀粒を乾燥させながら下部の螺旋搬送装置２８に円滑に流下させることができ、穀粒排出作業を能率良く行うことができるものでありながら、穀粒貯留装置４を縦軸Ｐを中心に外側方へ回動させても排気パイプ４５が回動しないため、該排気パイプ４５が機体１側に干渉して穀粒貯留装置４の回動量が規制されるのを防止することができる。 As shown in FIGS. 15 and 16, in the same configuration as in the third embodiment, an iron plate cover 49 integrally provided with a pipe 47 is provided on the outer surface of the bottom surface 31 of the grain storage device 4. You may comprise so that connection disconnection is possible. By comprising in this way, even when the stored grain is wet, it is possible to smoothly flow down to the lower spiral conveying device 28 while drying the grain, and to efficiently perform the grain discharging operation. Although the exhaust pipe 45 does not rotate even if the grain storage device 4 is rotated outwardly about the vertical axis P, the exhaust pipe 45 interferes with the machine body 1 side to store the grain. It is possible to prevent the amount of rotation of the device 4 from being restricted.
