JP 2003-235328 A

前記従来技術にあっては、前処理部で穀稈を搬送する搬送チエン、搬送ベルトや脱穀部で穀稈を搬送するフィードチエンは、常に低速で回転を開始して目標の回転数まで増速される構成であるが、フィードチエンの下手側の排稾搬送装置を所定速度で駆動する構成であるので、フィードチエンから排稾搬送装置への引継部で排藁が停滞し円滑に搬送できないという不具合があった。そこで、この発明はこのような不具合を解決しようとするものである。   In the prior art, the transport chain that transports the cereals in the pre-processing unit, and the feed chain that transports the cereals in the transport belt and the threshing unit always start rotating at a low speed and increase to the target rotational speed. However, since the waste transporting device on the lower side of the feed chain is driven at a predetermined speed, the waste is stagnated at the takeover portion from the feed chain to the waste transporting device and cannot be transported smoothly. There was a bug. Therefore, the present invention is intended to solve such a problem.

請求項1の発明は、コンバイン(1)の走行伝動経路に走行用無段変速装置(38)を設け、刈取搬送部(8)の穀稈搬送装置、フィードチエン(19)及び排稾搬送装置(21)の搬送速度を変速する搬送用無段変速装置(67)を設け、前記走行用無段変速装置(38)の変速に同調して搬送用無段変速装置(67)を関連的に変速することを特徴とするコンバインの穀稈搬送装置とする。   According to the first aspect of the present invention, a continuously variable transmission (38) for travel is provided in the travel transmission path of the combine (1), and the cereal transport device, feed chain (19), and rejecting transport device of the cutting transport unit (8). A continuously variable transmission (67) for shifting the transport speed of (21) is provided, and the continuously variable transmission for transport (67) is related to the shifting of the continuously variable transmission (38) for traveling. It is set as the combine cereal conveyance apparatus characterized by changing speed.

前記構成によると、走行用無段変速装置(38)を作動して走行装置を変速すると、この変速車速に同調した変速比により搬送用無段変速装置(67)も変速され、一連の刈取搬送部(8)の穀稈搬送装置、フィードチエン(19)及び排稾搬送装置(21)の搬送速度が同調して変速され穀稈及び排藁が搬送される。   According to the above configuration, when the travel continuously variable transmission (38) is operated to shift the travel device, the transport continuously variable transmission (67) is also shifted by a gear ratio synchronized with the speed of the shift vehicle, and a series of cutting and transporting operations are performed. The grain speeds of the grain haul conveying device, the feed chain (19) and the excavation conveying apparatus (21) of the section (8) are shifted in synchronism to convey the habit and waste.

請求項2の発明は、走行用無段変速装置(38)の変速に同調して搬送用無段変速装置(67)を関連的に変速するにあたり、走行変速レバー(82)を中立位置から前進高速側に操作し初期走行速度「0」から順次増速すると、これに同調して搬送用無段変速装置(67)が初期搬送速度「0」から順次増速することを特徴とする請求項1に記載のコンバインの穀稈搬送装置とする。   According to the second aspect of the present invention, when the transfer continuously variable transmission (67) is shifted relative to the shift of the traveling continuously variable transmission (38), the traveling shift lever (82) is moved forward from the neutral position. The speed of the continuously variable transmission (67) is gradually increased from the initial transport speed "0" in synchronization with the increase in speed from the initial running speed "0" when operated to the high speed side. It is set as the combine cereal conveyance apparatus of 1 described.

前記構成によると、請求項1の発明の前記作用に加えて、走行変速レバー(82)を中立位置から前進高速側に操作して初期走行速度「0」から順次増速すると、これに同調して搬送用無段変速装置(67)も初期搬送速度「0」から順次増速される。   According to the above configuration, in addition to the operation of the first aspect of the invention, when the traveling speed change lever (82) is operated from the neutral position to the forward high speed side and the speed is sequentially increased from the initial traveling speed "0", it is synchronized with this. Thus, the continuously variable transmission (67) for transport is also sequentially increased from the initial transport speed “0”.

請求項3の発明は、走行用無段変速装置(38)の変速に同調して搬送用無段変速装置(67)を関連的に変速するにあたり、走行変速レバー(82)を中立位置から前進高速側に操作し初期走行速度「0」から順次増速すると、これに同調して搬送用無段変速装置(67)を初期所定搬送速度から順次増速することを特徴とする請求項1に記載のコンバインの穀稈搬送装置とする。   According to the third aspect of the present invention, the traveling speed change lever (82) is moved forward from the neutral position when the transporting continuously variable transmission (67) is shifted relative to the shifting of the traveling continuously variable transmission (38). 2. The continuously variable transmission device (67) is sequentially increased from an initial predetermined conveying speed in synchronism with an increase in speed from the initial running speed “0” when operated to the high speed side. It is set as the combine harvester conveying apparatus of description.

前記構成によると、請求項1の発明の前記作用に加えて、走行変速レバー(82)を中立位置から前進高速側に操作し初期走行速度「0」から順次増速すると、これに同調して搬送用無段変速装置(67)を初期所定搬送速度から順次増速される。   According to the above configuration, in addition to the operation of the invention of claim 1, when the traveling speed change lever (82) is operated from the neutral position to the forward high speed side to increase the speed sequentially from the initial traveling speed “0”, The continuously variable transmission (67) for conveyance is sequentially increased from the initial predetermined conveyance speed.

請求項1の発明は、刈取穀稈の一連の搬送系である刈取搬送部(8)の穀稈搬送装置、フィードチエン(19)及び排稾搬送装置(21)が車速に同調して変速されるので、搬送途中で穀稈がつまるようなこともなく、穀稈を安定して搬送することができる。   According to the first aspect of the present invention, the grain feeder, the feed chain (19), and the waste conveyor (21) of the harvesting conveyor (8), which is a series of conveyor systems for the harvested grains, are shifted in synchronization with the vehicle speed. Thus, the cereals can be stably conveyed without causing the cereals to become clogged during the conveyance.

請求項2の発明は、請求項1の発明の前記効果に加えて、走行装置の初速走行速度「0」からの増速に関連して、搬送用無段変速装置(67)を初搬送速度「0」から車速に同調して増速変速され、一連の刈取搬送部(8)の穀稈搬送装置、フィードチエン(19)及び排稾搬送装置(21)の搬送速度が車速に同調して変速されるので、刈取作業開始時から穀稈の搬送を開始して穀稈のこぼれを防止し、刈取作業中は搬送穀稈の層厚を一定にしながら安定して搬送することができる。   In addition to the above-mentioned effect of the invention of claim 1, the invention of claim 2 relates to the continuously variable transmission (67) for transfer in relation to the speed increase from the initial speed travel speed “0” of the travel device. From "0", the speed is increased and synchronized with the vehicle speed, and the conveying speeds of the grain feeder, feed chain (19) and waste conveyor (21) of the series of cutting and conveying units (8) are synchronized with the vehicle speed. Since the speed is changed, the transportation of the cereal can be started from the start of the cutting operation to prevent the spilling of the cereal, and the cereal can be stably transported while the layer thickness of the transporting cereal is kept constant during the cutting operation.

請求項3の発明は、請求項1の発明の前記効果に加えて、走行用無段変速装置(38)の初期走行速度「0」からの増速変速に関連して、一連の刈取搬送部(8)の穀稈搬送装置、フィードチエン(19)及び排稾搬送装置(21)の搬送速度が、初期走行速度「0」に対して所定搬送速度から同調して変速されるので、刈取作業開始時から穀稈を初期所定速度で搬送することができ、穀稈のこぼれを防止しながら穀稈を安定して搬送することができる。   According to a third aspect of the present invention, in addition to the effect of the first aspect of the invention, a series of cutting and conveying sections is associated with the speed increasing shift from the initial traveling speed “0” of the continuously variable transmission (38) for traveling. Since the conveying speeds of the grain haul conveying device, the feed chain (19) and the waste conveying device (21) in (8) are shifted in synchronization with the initial traveling speed “0” from the predetermined conveying speed, the cutting operation is performed. The cereal can be conveyed at an initial predetermined speed from the start, and the cereal can be stably conveyed while preventing spillage of the cereal.

なお、掻込スイッチSW4及び増速スイッチSW5は走行変速レバー82の握り部に設けている。
前記構成によると、車速同調スイッチSW1をONすると、第一HST38の変速による車速に対して第二HST67が所定比率で同調して変速され、刈取搬送部8の穀稈掻込装置8a、穀稈集送搬送装置8b、穀稈引継搬送装置8c、フィードチエン19及び排稾搬送装置21が車速に同調した変速比で穀稈及び排藁を搬送する。また、一定速度スイッチSW2をONすると、車速の変速とは無関係に一定速度で穀稈及び排藁を搬送する。
The take-in switch SW4 and the speed increasing switch SW5 are provided in the grip portion of the traveling speed change lever 82.
According to the above configuration, when the vehicle speed synchronization switch SW1 is turned ON, the second HST 67 is synchronized with a predetermined ratio with respect to the vehicle speed due to the first HST 38 speed change, and the grain picking device 8a, grain The collecting and conveying device 8b, the cereal takeover conveying device 8c, the feed chain 19 and the waste conveying device 21 convey the cereal and waste with a gear ratio synchronized with the vehicle speed.
