【発明の属する技術分野】
本発明は、脱穀フィードチェーンによって刈取穀稈の株元側を挟持搬送してその穂先側を扱室に供給し、脱穀部からの処理物を揺動選別装置と、唐箕からの選別風によって選別処理して一番選別処理物を１番スクリューコンベヤによって搬送し、二番選別処理物を２番スクリューコンベヤによって搬送するように構成し、脱穀排ワラを切断軸が一体回動自在に有する切断刃と、供給軸が一体回動自在に有する供給刃によって細断処理する排ワラ細断装置を備えるとともに、前記排ワラ細断装置に、駆動力を切断軸に入力し、切断軸の駆動力を減速して供給軸に伝達する細断駆動部を備えてある排ワラ細断装置付き脱穀機に関する。
【０００２】
【従来の技術】
排ワラ細断装置を備えた脱穀機において、従来、たとえば特許文献１に示されるように、唐箕軸５Ａ（唐箕の回転支軸に相当）の出力プーリ２１と、一番物回収装置６（１番スクリューコンベヤに相当）の入力プーリ２２と、二番物回収装置７（２番スクリューコンベヤに相当）の入力プーリ２３と、揺動選別装置４の入力プーリ２４と、排ワラ細断装置２５の入力プーリ２６にわたって伝動ベルト２８を張設し、揺動選別装置４の駆動軸３３の出力プーリ３４（選別駆動プーリに相当）と、フィードチェーン１の入力プーリ３５にわたって伝動ベルト３６を張設しているものがあった。
【０００３】
【特許文献１】
特開平１０−３３０４９号公報（〔００１６〕欄、図６）
【０００４】
【発明が解決しようとする課題】
唐箕の回転支軸から各スクリューコンベヤであるとか揺動選別装置や排ワラ細断装置に動力伝達するとともに脱穀フィードチェーンに動力伝達する場合、脱穀フィードチェーンの駆動速度が、スクリューコンベヤや排ワラ細断装置の駆動速度に比して低速になるように、脱穀フィードチェーンに対して減速伝動する手段が必要になる。
上記した従来の駆動技術を採用した場合、揺動選別装置４の駆動軸３３の出力プーリ３４とフィードチェーン１の入力プーリ３５にわたって張設された伝動ベルト３６であるとか、前記入力プーリ３５をフィードチェーン１の駆動スプロケットに伝達する伝動機構によって、脱穀フィードチェーン１に対する減速伝動手段を構成する必要がある。この場合、減速伝動手段が脱穀フィードチェーンのための専用の減速伝動手段なり、経済面や重量面で不利になりやすくなっていた。また、減速伝動手段が脱穀フィードチェーンから排ワラ搬送装置に脱穀排ワラを供給される部位の下方に位置し、その排ワラ供給の際に発生しやすいワラ屑が減速伝動手段の上に落下して堆積する事態が発生しやすくなっていた。
【０００５】
本発明の目的は、唐箕の回転支軸から各スクリューコンベヤや揺動選別装置、排ワラ細断装置や脱穀フィードチェーンに対して構造簡単に動力伝達する割には、脱穀フィードチェーン専用の減速手段を不要にしながら脱穀フィードチェーンを適切な駆動速度で駆動できる排ワラ細断装置付き脱穀機を提供することにある。
【０００６】
【課題を解決するための手段】
請求項１による発明の構成、作用、効果はつぎのとおりである。
【０００７】
〔構成〕
脱穀フィードチェーンによって刈取穀稈の株元側を挟持搬送してその穂先側を扱室に供給し、脱穀部からの処理物を揺動選別装置と、唐箕からの選別風によって選別処理して一番選別処理物を１番スクリューコンベヤによって搬送し、二番選別処理物を２番スクリューコンベヤによって搬送するように構成し、脱穀排ワラを切断軸が一体回動自在に有する切断刃と、供給軸が一体回動自在に有する供給刃によって細断処理する排ワラ細断装置を備えるとともに、前記排ワラ細断装置に、駆動力を切断軸に入力し、切断軸の駆動力を減速して供給軸に伝達する細断駆動部を備えてある排ワラ細断装置付き脱穀機において、
前記唐箕の回転支軸に一体回転自在に支持させた出力プーリ、１番スクリューコンベヤの１番スクリュー入力プーリ、２番スクリューコンベヤの２番スクリュー入力プーリ、前記揺動選別装置を駆動する選別駆動プーリ、前記細断駆動部の細断入力プーリにわたって同一の伝動ベルトを巻回し、前記供給軸の前記細断入力プーリが位置する側の端部にフィードチェーン駆動スプロケットを一体回動自在に支持させるとともに、このフィードチェーン駆動スプロケットに前記脱穀フィードチェーンを巻回してある。
【０００８】
〔作用〕
唐箕の回転支軸の駆動力が出力プーリによって伝動ベルトに伝達され、この伝動ベルトによって、１番スクリュー入力プーリ、２番スクリュー入力プーリ、選別駆動プーリ、細断入力プーリに伝達され、細断入力プーリから細断駆動部によって供給軸に伝達されてこの供給軸から脱穀フィードチェーン駆動スプロケットに伝達される。細断駆動部が切断軸の駆動力を減速して供給軸に伝達するから、この減速伝動のために、脱穀フィードチェーン駆動スプロケットの駆動速度が、細断入力プーリであるとか各スクリュー入力プーリの駆動速度の割には低速になり、各スクリューコンベヤや揺動選別装置であるとか排ワラ細断装置の切断刃が搬送や選別あるいは排ワラ切断に必要な駆動速度で駆動され、脱穀フィードチェーンがスクリューコンベヤや切断刃の駆動速度に比して低速の所要速度で駆動される。
【０００９】
〔効果〕
従って、唐箕回転支軸の駆動力を各スクリューコンベヤ、揺動選別装置、排ワラ細断装置、脱穀フィードチェーンに伝達してこれらを駆動するのに、各入力プーリおよび選別駆動プーリに動力伝達する伝動ベルトを同一にし、かつ、排ワラ細断装置の駆動のための細断駆動部を脱穀フィードチェーンに対する減速伝動手段に利用した構造簡単な伝動構造によって駆動でき、軽量化するとかコストダウンできる。
さらに、排ワラ細断装置の細断駆動部を脱穀フィードチェーンに対する減速伝動手段に利用していることによって脱穀フィードチェーン専用の減速手段が不要になり、この面からも軽量化できるとか、冒頭に記したワラ屑堆積などのトラブル発生を回避できる。

JP-A-10-33049 (column [0016], FIG. 6)
[0004]
[Problems to be solved by the invention]
When power is transmitted from the rotary support shaft to the screw conveyor or to the oscillating sorting device or the waste straw shredding device and also to the threshing feed chain, the drive speed of the threshing feed chain is adjusted to A means for decelerating transmission to the threshing feed chain is required so that the driving speed of the cutting device is low.
When the above-described conventional driving technique is adopted, the transmission pulley 36 is stretched over the output pulley 34 of the drive shaft 33 of the swing sorting device 4 and the input pulley 35 of the feed chain 1, or the input pulley 35 is fed. It is necessary to constitute a speed reduction transmission means for the threshing feed chain 1 by a transmission mechanism that transmits the drive sprocket of the chain 1. In this case, the speed reduction transmission means becomes a dedicated speed reduction transmission means for the threshing feed chain, which tends to be disadvantageous in terms of economy and weight. Further, the deceleration transmission means is located below the part where the threshing waste straw is supplied from the threshing feed chain to the waste straw conveying device, and the straw waste that is likely to be generated during the supply of the waste straw falls on the deceleration transmission means. It was easy to occur.
[0005]
The object of the present invention is to reduce the speed reduction means dedicated to the threshing feed chain for the simple structure of power transmission from the rotary support shaft of the carp to each screw conveyor, the swing sorting device, the waste straw shredding device and the threshing feed chain. An object of the present invention is to provide a threshing machine with a draining shredding device capable of driving a threshing feed chain at an appropriate driving speed while eliminating the need for a threshing.
[0006]
[Means for Solving the Problems]
The structure, operation, and effect of the invention according to claim 1 are as follows.
[0007]
〔Constitution〕
The threshing feed chain sandwiches and conveys the stock side of the harvested cereal, supplies the tip side to the handling room, and sorts the processed product from the threshing part using the oscillating sorting device and the sorting wind from the tang. A cutting blade in which the number-sorted processed product is conveyed by the No. 1 screw conveyor, the number-sorted processed material is conveyed by the No. 2 screw conveyor, and the cutting shaft has a threshing waster that can be rotated integrally with the cutting shaft, and a supply shaft Is equipped with a waste wall shredding device that performs shredding with a supply blade that can be rotated integrally, and the driving force is input to the cutting shaft and the driving force of the cutting shaft is decelerated and supplied to the waste wall shredding device. In a threshing machine with a draining shredding device that has a shredding drive that transmits to the shaft,
An output pulley that is rotatably supported by the rotary shaft of the carp, a first screw input pulley of a No. 1 screw conveyor, a No. 2 screw input pulley of a No. 2 screw conveyor, and a sorting drive pulley that drives the swing sorter The same transmission belt is wound around the chopping input pulley of the chopping drive unit, and the feed chain drive sprocket is supported so as to be integrally rotatable at the end of the supply shaft where the chopping input pulley is located. The threshing feed chain is wound around the feed chain drive sprocket.
[0008]
[Action]
The driving force of the rotary shaft of Karatsu is transmitted to the transmission belt by the output pulley, which is transmitted to the No. 1 screw input pulley, No. 2 screw input pulley, the sorting drive pulley, and the shredded input pulley. It is transmitted from the pulley to the supply shaft by the shredding drive unit, and from this supply shaft to the threshing feed chain drive sprocket. Since the chopping drive unit decelerates the driving force of the cutting shaft and transmits it to the supply shaft, the driving speed of the threshing feed chain drive sprocket is the chopping input pulley or the screw input pulley for this deceleration transmission. The cutting speed of each screw conveyor or swing sorter or the cutting machine of the draining shredder is driven at the driving speed required for conveyance, sorting or cutting of the draining wall, and the threshing feed chain is It is driven at a required speed that is lower than the drive speed of the screw conveyor and the cutting blade.
[0009]
〔effect〕
Therefore, the driving force of the rotary rotation support shaft is transmitted to each screw conveyor, swing sorting device, waste straw shredding device, threshing feed chain to drive them, and power is transmitted to each input pulley and sorting drive pulley. The transmission belt can be made the same, and the chopping drive portion for driving the draining chopping device can be driven by a simple transmission structure using the speed reduction transmission means for the threshing feed chain, and the weight can be reduced or the cost can be reduced.
Furthermore, by using the shredding drive part of the waste straw shredding device as a speed reduction transmission means for the threshing feed chain, a speed reduction means dedicated to the threshing feed chain is no longer necessary, and it is possible to reduce the weight from this aspect as well. Troubles such as the accumulation of straw scraps can be avoided.
