【0022】
前記脱穀機3の前側下部には、図1で示す如く供給される穀稈を挟持移送するフィードチェン6を、前下側板10dの前側に設けると共に、挟持杆14を、前上側板10cの前側に設けた、支持具15で支持した構成である。これらフィードチェン6と、挟持杆14とにより、挟持移送される穀稈の層厚を検出する層厚センサ7を、挟持杆14の上側へ設けた構成である。
【0023】
前記挟持杆14は、図1で示す如くコ字形状の挟持プレート14aへ支持軸14bを固着して設け、この支持軸14bの外側で、支持プレート14aと、支持具15との間には、弾発するスプリング14cを設けた構成であり、又、支持軸14bは、支持具15で上下摺動自在に設けた構成である。
【0024】
前記支持具15の上側には、U字形状の支持板15aを設け、この支持板15aには、回動軸15bを軸支すると共に、回動軸15bには、アーム15cを固着して設け、このアーム15cの先端部には、挟持杆14の支持軸14bの上端へ装着した構成である。挟持杆14の支持軸14bの上下摺動移動により、アーム15cを介して回動軸15bが回動され、この回動量を検出して、挟持杆14と、フィードチェン6との間に挟持された穀稈の層厚を検出するポテンションメータ方式の層厚センサ7を、回動軸15bへ軸支した構成である。
【0025】
前記層厚センサ7で検出される。フィードチェン5と、挟持杆14との間に挟持されて、移送される穀稈の層厚により、例えば、検出される層厚量が、所定量増加して厚くなったことを検出に伴なって、回転体4の前支持軸13aへ軸支した入力プーリ13eへ入力される回転速度は、所定速度増速回転に、脱穀機3に設けた制御装置18により、変更制御される構成である。この増速回転の制御は、検出される層厚の増加量を順次段階に区切り、この段階的に区切られた増加量毎に、回転体4の回転速度を段階的に増速回転に、制御装置18で変更制御される構成である。又は、所定量以上の層厚の検出により、所定回転速度以上の回転速度に、この制御装置18で変更制御される構成である。
【0026】
帯状材で形成した回転体4へ穀稈を脱穀する各処理手段5を設けると共に、フィードチェン6と、挟持杆14とで挟持移送中の穀稈の層厚は、層厚センサ7で検出され、穀稈の検出層厚が厚くなるに伴なって、回転体4の回転速度を増速回転へ制御装置18で変更制御することにより、穀稈脱穀装置2の構成がコンパクトになると共に、脱穀性能の安定を図ることができる。
【0027】
前記回転体4の外周外側面に設けた複数個の処理手段5は、図1で示す如く弾性材である樹脂材の、例えば、耐久性、耐摩耗性のあるナイロン材の丸棒材等で形成した構成である。
前記回転体4の各処理手段5の回転外周の下部には、図1で示す如く脱穀処理物が漏下する脱穀網8を張設した構成である。この脱穀網8の内側面で、脱穀する穀稈の穂先部が位置する箇所には、円周方向に所定間隔で、板状、又は丸棒状等の突起体9を設けた構成である。
【0028】
前記回転体4の各処理手段5の先端部は、図2で示す如く脱穀網8に設けた各突起体9へ当接する構成である。この当接により、各処理手段5は、その反発する復元力により、穀稈に付着する穀粒へ脱粒作用して、脱穀する構成である。
穀稈を脱穀する前記回転体4の各処理手段5は、弾性材で形成すると共に、この各処理手段5は、脱穀網8に設けた各突起体9へ当接し、反発する復元力により、脱粒作用する構成としたことにより、回転体4の回転速度を低速度にすることができ、このために、この回転体4の振動の低減を図ることができる。又、藁屑、及び穂切等の発生が少なく、穀粒ロス、枝梗粒発生、脱ぷ粒発生、損傷粒発生を大巾に減少させることができる。
【0029】
前記脱穀網8の下側には、図1で示す如くこの脱穀網8から漏下する脱穀処理物の供給を受けて、穀粒と、藁屑、及び稈切等とに揺動選別する揺動選別装置16を設けた構成である。この揺動選別装置16の下側には、送風羽根17aを回転自在に軸支した送風機17を設けた構成である。この送風機17の送風羽根17aから発生する起風により、揺動選別装置16から落下する落下物を、穀粒と、藁屑等とに風選別する構成である。
【0030】
前記脱穀機1の脱穀室3内へ回転自在に軸支した帯状材で形成した回転体4には、図1、及び図2で示す如く穀稈を脱穀する弾性材で形成した各処理手段5を設け、この各処理手段5は、脱穀処理物が漏下する脱穀網8に設けた各突起体9へ当接し、反発する復元力により、脱粒作用する構成とすると共に、穀稈を挟持して脱穀室3内を移送するフィードチェン6と、挟持杆14とで挟持移送中の穀稈の層厚を検出する層厚センサ7を挟持杆14の上側へ設けた構成である。
【0031】
前記層厚センサ7により、フィードチェン6と、挟持杆14とで挟持移送中の穀稈の層厚が検出され、検出穀稈の層厚が厚くなったことを検出に伴なって、回転体4の回転速度を所定速度増速回転に制御装置18により、変更制御される構成である。この増速回転制御は、検出される層厚の増加量を順次段階に区切り、この段階的に区切られた増加量毎に、回転体4の回転速度を段階的に増速回転に、制御装置18で変更制御される構成である。又は、所定量以上の層厚の検出により、所定回転速度以上の回転速度に、この制御装置18で変更制御される構成である。
【0032】
前記脱穀機1の脱穀室3内へ回転自在に軸支した帯状材で形成した回転体4には、図1で示す如く穀稈を脱穀する弾性材で形成した各処理手段5を設けると共に、脱穀する穀稈を挟持移送するフィードチェン6と、挟持杆14を設け、挟持移送される穀稈の層厚を検出する層厚センサ7を設けた構成において、層厚センサ7で検出される検出層厚が厚くなるに伴なって、回転体4の回転速度を所定速度増速回転と、フィードチェン6の回転速度を所定速度増速回転とに、制御装置18で変更制御する構成である。
【0033】
前記回転体4と、フィードチェン6との回転速度を増速回転に制御は、検出層厚の増加を順次段階に区切って、段階的に増速回転制御とするか、又は、検出層厚の増加が所定量以上の検出により、所定回転速度以上の増速回転速度に、制御装置18で変更制御する構成である。
【0034】
前記フィードチェン6で挟持移送される穀稈の層厚は、層厚センサ7で検出され、穀稈の検出する層厚が厚くなることに伴なって、回転体4、及びフィードチェン6の回転速度を所定速度増速回転へ変更制御することにより、このフィードチェン6のスピードの早いときは、脱穀室3内を通過する時間が速いので、回転体4の回転数を上げ脱粒作用を多くして、扱ぎ残り粒、三番・四番ロスの低減を図ることができて、脱穀性能の向上を図ることができる。又、フィードチェン6のスピードが遅いときには、脱穀室3内を通過する時間が長いので、回転体4の回転数を下げることで、穂切粒、及び藁屑等の発生が防止できて、選別性能の向上を図ることができる。
【0035】
前記回動体4の前・後支持軸13a,13bを軸支する各支持メタル19は、図3、及び図4で示す如く脱穀機3の左・右側板10a,10bの上下両側に設けた取付ピン20,20には、各支持メタル19の上下両側に設けた長孔19b,19b部を挿入して、ナット等により、上下摺動自在に装着した構成であると共に、各支持メタル19の上下方向中央部の長孔19aには、前・後支持軸13a,13cを挿入した構成である。
【0036】
前記脱穀機3の左・右側板10a,10bの前後両側に設けた各支持メタル19の下側には、各調節板21を設けると共に、油圧駆動による各伸縮シリンダ22を設けて、各調節板21へ挿入して、各支持メタル19を支持した構成である。各伸縮シリンダ22の伸縮作動により、回転体4は、上下に摺動移動する構成である。
【0037】
前記脱穀室3内には、この脱穀室3内に脱穀処理物の有無を検出する脱穀センサ23を設け、この脱穀物センサ23が脱穀室3内に脱穀処理物がないと検出すると、この検出に連動して、伸縮シリンダ22が作動して、回転体4を所定距離上部へ上昇操作して、この回動体4の各処理手段5が、脱穀網8に設けた各突起体9へ当接しない構成である。
【0038】
これにより、前記脱穀室3内に脱穀処理物がないと、脱穀物センサ23が検出すると、回動体4が上方へ上昇制御されることにより、回動体4の各処理手段5が、脱穀網8に設けた各突起体9へ当接することがなくなり、異音の発生が防止できる。又、各処理手段5等の摩耗が防止できて、耐久性の向上を図ることができる。
【0039】
前記脱穀網8に設けた突起体9は、図1で示す如く脱穀する穀稈の穂先部が位置する箇所に設けた構成である。
これにより、前記脱穀網8に設けた突起体9は、穀稈の穂先部でのみ作用するように設けたことにより、藁屑の発生が防止できる。又、穀稈脱穀装置2を簡素化できることにより、脱穀機3のコストダウンを図ることができる。
【0040】
前記脱穀網8には、図5、及び図6で示す如く突起装置24を上下移動自在に設けた構成である。この突起装置24は、支持杆24aの上側面には、複数本の突起体24bを固着して設け、この各突起体24bが脱穀網8内を上下に移動して、回転体4の各処理手段5の下端部と、突起体24bの上端部との重合状態を、最小(L1)から最大(L2)に調節できる構成である。
【0041】
これにより、前記回転体4の処理手段5と、突起装置24の突起体24bとの重合状態を変更できる構成としたことにより、処理手段5の反発する復元力を調節でき、このために、穀稈の品種条件、及び脱粒条件等に対する条件適応性の向上を図ることができる。
【0042】
前記脱穀機1は、上扱ぎ構成としたものである。この脱穀機1の穀稈脱穀装置2の上部の前側には、図7、及び図8で示す如く穀稈を扱ぎするための、穀稈を挟持移送する挟持杆14と、この挟持杆14の下側に、フィードチェン6を設けた構成である。
【0043】
前記穀稈脱穀装置2の脱穀室3へ回転自在に軸支した回転体4の外周外側面には、丸棒材よりなる十字形状の処理手段25を回転方向、及び左右方向に所定間隔に設けた構成である。この処理手段25で脱穀された脱穀処理物は、回転体4上へ落下し、この回転体4上を下部へ向けて移送され、脱穀室3の下部へ張設した脱穀網8から漏下する構成である。この脱穀網8には、所定間隔で複数個の突起体9を設けて、脱穀処理物の漏下を良好にした構成である。
【0044】
前記処理手段25は、弾性材である樹脂材の、例えば、耐久性、耐摩耗性のあるナイロン材の丸棒材等で形成した構成であり、脱穀中の穀稈の穂先側が、処理手段25の十字形状の横方向側への丸棒材へ特にからみ付き脱粒性の向上を図った構成である。
【0045】
これにより、前記脱穀機1を上扱ぎとしたが、回転体4に設けた処理手段25を十字形状の丸棒材としたことにより、穀稈が回転体4へ付着することがなく、処理手段25の横、及び縦方向側の丸棒部へからみつくことにより、脱粒性を向上させることができる。又、脱穀網8部に穀稈がなく、脱穀処理物の漏下が良好となり、三番飛散粒、及び四番飛散粒の減少を図ることができる。
【0046】
上扱ぎ用の前記脱穀機1の脱穀室3の下部に張設した脱穀網8には、図7で示す如く複数個の突起体9を設けると共に、天井板11bの内側面で穀稈の穂先部が位置する箇所には、所定間隔で下側の突起体9と同じ形状の上突起体9aを設けた構成である。
【0047】
これにより、前記各上突起体9aで脱粒性の向上を図ることができ、下側の各突起体9で脱穀処理物の漏下の向上を図ることができる。
上扱ぎ用の前記脱穀機1の脱穀室3内へ回転自在に軸支した回転体4へ円周方向、及び左右方向へ所定間隔で装着して設けた各処理手段25は、図9で示す如く左右方向に設けた各縦桟25aを横桟25bで接続した構成である。
【0048】
これにより、前記各処理手段25の縦桟25aを横桟25bで接続させたことにより、脱穀中の穀稈は横桟25b部で止まり、これにより、縦・横桟25a,25bへ穀稈の穂先部が絡みつくことにより、脱粒性の向上を図ることができる。又、強度アップを図ることができる。
【0049】

[0027]
The plurality of processing means 5 provided on the outer peripheral surface of the rotating body 4 are made of a resin material which is an elastic material, for example, a round bar made of a durable and wear-resistant nylon material as shown in FIG. It is a formed configuration.
As shown in FIG. 1, a threshing net 8 through which threshing products leak is provided below the rotation outer periphery of each processing means 5 of the rotating body 4. On the inner surface of the threshing net 8, plate-shaped or round-bar-shaped projections 9 are provided at predetermined intervals in the circumferential direction at locations where the tip of the grain stem to be threshed is located.
[0028]
As shown in FIG. 2, the tip of each processing means 5 of the rotating body 4 is configured to abut against each projection 9 provided on the threshing net 8. Due to this contact, each processing means 5 is configured to thresh the grains adhering to the grain stem by the repelling restoring force and thresh.
Each processing means 5 of the rotating body 4 for threshing the grain stem is formed of an elastic material, and each of the processing means 5 abuts on each of the projections 9 provided on the threshing net 8 and rebounds by a restoring force. By adopting the structure that performs the particle shedding operation, the rotation speed of the rotating body 4 can be reduced, and therefore, the vibration of the rotating body 4 can be reduced. In addition, the generation of straw chips, cuttings of ears and the like is small, and it is possible to significantly reduce the occurrence of grain loss, the occurrence of branch stalks, the occurrence of flaking grains, and the occurrence of damaged grains.

With the blast generated from the blower blades 17a of the blower 17, falling objects falling from the swinging sorting device 16 are sorted into grains, straw chips, and the like.
[0030]
A rotating body 4 formed of a band-shaped material rotatably supported in a threshing chamber 3 of the threshing machine 1 includes a processing means 5 formed of an elastic material for threshing a grain culm as shown in FIGS. Each of the processing means 5 is configured to abut against each of the protrusions 9 provided on the threshing net 8 from which the threshing processing material leaks, to perform a threshing action by a rebounding resilience, and to pinch the grain culm. A feed chain 6 for transporting the inside of the threshing chamber 3 by means of the threshing chamber 3, and a layer thickness sensor 7 for detecting the layer thickness of the culm being clamped and transported by the clamping rod 14 are provided above the clamping rod 14.
[0031]
The layer thickness sensor 7 detects the layer thickness of the cereal stalk being nipped and transported by the feed chain 6 and the nipping rod 14, and detects that the layer thickness of the detected cereal stalk has become thicker, The control device 18 changes and controls the rotation speed of the motor 4 to a predetermined speed increased rotation. In this speed-up rotation control, the detected increase amount of the layer thickness is sequentially divided into stages, and the rotation speed of the rotating body 4 is increased stepwise at each of the increase amounts divided in steps, This is a configuration that is controlled to be changed at 18. Alternatively, the controller 18 changes the rotation speed to a rotation speed equal to or higher than a predetermined rotation speed by detecting a layer thickness equal to or more than a predetermined amount.
[0032]
A rotating body 4 formed of a band-shaped material rotatably supported in a threshing chamber 3 of the threshing machine 1 is provided with respective processing means 5 formed of an elastic material for threshing grain culms as shown in FIG. In a configuration in which a feed chain 6 for pinching and transporting a grain culm to be threshed and a pinching rod 14 and a layer thickness sensor 7 for detecting the layer thickness of the grain culm to be pinched and transported are detected by the layer thickness sensor 7. As the layer thickness increases, the controller 18 changes and controls the rotation speed of the rotating body 4 to a predetermined speed-up rotation and the rotation speed of the feed chain 6 to a predetermined speed-up rotation.
[0033]
The control of the rotation speed of the rotating body 4 and the feed chain 6 to the speed-up rotation is performed by sequentially increasing the detection layer thickness in stages and performing speed-up rotation control in a stepwise manner. When the increase is greater than or equal to a predetermined amount, the control unit 18 controls the rotation speed to be increased to a predetermined rotation speed or higher.
[0034]
The layer thickness of the grain culm conveyed by the feed chain 6 is detected by a layer thickness sensor 7. As the layer thickness of the grain culm increases, the rotation of the rotating body 4 and the feed chain 6 is increased. When the speed of the feed chain 6 is high, the time required to pass through the threshing chamber 3 is high when the speed of the feed chain 6 is high, so that the rotation speed of the rotating body 4 is increased to increase the threshing action. As a result, it is possible to reduce untreated particles and third and fourth losses, and to improve threshing performance. In addition, when the speed of the feed chain 6 is low, since the time required to pass through the threshing chamber 3 is long, the rotation speed of the rotating body 4 can be reduced to prevent the occurrence of cutting ears, straw chips, and the like. The performance can be improved.
[0035]
Each of the support metals 19 that support the front and rear support shafts 13a and 13b of the rotating body 4 is mounted on the upper and lower sides of the left and right plates 10a and 10b of the threshing machine 3 as shown in FIGS. Slots 19b, 19b provided on both upper and lower sides of each support metal 19 are inserted into the pins 20, 20, and are vertically slidably mounted with nuts and the like. The front and rear support shafts 13a and 13c are inserted into the elongated hole 19a at the center in the direction.
[0036]
Under each support metal 19 provided on the front and rear sides of the left and right plates 10a and 10b of the threshing machine 3, each adjusting plate 21 is provided, and each telescopic cylinder 22 driven by hydraulic pressure is provided. 21 to support each supporting metal 19. The rotating body 4 is configured to slide up and down by the expansion and contraction operation of each of the expansion and contraction cylinders 22.
[0037]
The threshing room 3 is provided with a threshing sensor 23 for detecting the presence or absence of a threshing product in the threshing room 3. When the threshing sensor 23 detects that there is no threshing product in the threshing room 3, this detection is performed. In conjunction with the operation, the telescopic cylinder 22 is actuated, and the rotating body 4 is moved upward by a predetermined distance so that each processing means 5 of the rotating body 4 comes into contact with each of the projections 9 provided on the threshing net 8. No configuration.
[0038]
Accordingly, when the threshing sensor 23 detects that there is no threshing product in the threshing chamber 3, the rotating body 4 is controlled to move upward, so that each of the processing means 5 of the rotating body 4 includes the threshing net 8. Is no longer in contact with each of the projections 9 provided on the base member, and generation of abnormal noise can be prevented. Further, wear of each processing means 5 and the like can be prevented, and durability can be improved.
[0039]
The protrusions 9 provided on the threshing net 8 are provided at positions where the ears of the grain stem to be threshed are located as shown in FIG.
Thus, the projections 9 provided on the threshing net 8 are provided so as to act only at the tip of the grain stem, thereby preventing the generation of straw waste. Further, since the stalk threshing device 2 can be simplified, the cost of the threshing machine 3 can be reduced.
[0040]
As shown in FIGS. 5 and 6, the threshing net 8 has a configuration in which a projection device 24 is provided so as to be vertically movable. In the projection device 24, a plurality of projections 24b are fixedly provided on the upper side surface of the support rod 24a, and each of the projections 24b moves up and down in the threshing net 8 so that each processing of the rotating body 4 is performed. The superimposed state of the lower end of the means 5 and the upper end of the projection 24b can be adjusted from the minimum (L1) to the maximum (L2).
[0041]
This makes it possible to change the state of polymerization of the processing means 5 of the rotating body 4 and the projection 24b of the projection device 24, so that the repulsive restoring force of the processing means 5 can be adjusted. It is possible to improve the condition adaptability to the cultivar condition, the shedding condition and the like.
[0042]
The threshing machine 1 has an upper handling configuration. As shown in FIGS. 7 and 8, a gripping rod 14 for gripping and transferring the cereal stem, and a gripping rod 14 are provided on the front side of the upper part of the culm threshing device 2 of the threshing machine 1. In this configuration, a feed chain 6 is provided on the lower side.
[0043]

Configuration. The thresh-processed product threshed by the processing means 25 falls onto the rotating body 4, is transported downward on the rotating body 4, and leaks from the threshing net 8 stretched to the lower part of the threshing chamber 3. Configuration. The threshing net 8 has a configuration in which a plurality of projections 9 are provided at predetermined intervals so that the threshing processed material can be easily leaked.
[0044]
The processing means 25 is formed of a resin material which is an elastic material, for example, a round bar made of a durable and abrasion-resistant nylon material or the like. In particular, the cross-shaped round bar material on the side in the cross direction is entangled to improve the shedding performance.
[0045]
As a result, the threshing machine 1 was handled as an upper part, but the processing means 25 provided on the rotating body 4 was made of a cross-shaped round bar, so that the grain stalk did not adhere to the rotating body 4 and the processing was performed. By sticking to the round bar portions on the horizontal and vertical sides of the means 25, the shedding performance can be improved. Further, since there is no grain culm in the threshing net 8 part, the leakage of the thresh-processed product is good, and the third and fourth scattered grains can be reduced.
[0046]
As shown in FIG. 7, a plurality of projections 9 are provided on a threshing net 8 stretched below the threshing chamber 3 of the threshing machine 1 for overhand handling, and grain culms are formed on the inner surface of the ceiling plate 11b. An upper protrusion 9a having the same shape as the lower protrusion 9 is provided at a predetermined interval at a position where the tip portion is located.
[0047]
This makes it possible to improve the shedding performance of each of the upper projections 9a, and to improve the leakage of the thresh-processed product at each of the lower projections 9.
Each of the processing means 25 provided at predetermined intervals in the circumferential direction and the left and right direction on the rotating body 4 rotatably supported in the threshing chamber 3 of the threshing machine 1 for upper handling is shown in FIG. As shown in the figure, each of the vertical rails 25a provided in the left-right direction is connected by a horizontal rail 25b.
[0048]
As a result, by connecting the vertical rails 25a of the respective processing means 25 with the horizontal rails 25b, the grain culm during threshing stops at the horizontal rails 25b, whereby the grain culms are transferred to the vertical and horizontal rails 25a, 25b. The tangling of the tip can improve the shedding performance. Further, the strength can be increased.
[0049]
In the threshing room 3 of the threshing machine 1, as shown in FIG. 10 and FIG. The upper rotating body 26 is rotatably supported and provided. In the circumferential direction and the left-right direction of the upper rotating body 26, a plurality of upper shedding bodies 26a are provided at predetermined intervals. On the lower side, in the front-rear direction, a lower rotating body 27 that is longer than the upper rotating body 26 by a predetermined length and has the same width as the upper rotating body 26 is rotatably supported by the upper rotating body 26 in a reverse rotation. is there. In the circumferential direction and the left-right direction of the lower rotating body 27, a plurality of lower shedding bodies 27a of substantially the same shape are provided at the same position as the upper shedding body 26a of the upper rotating body 26.
[0050]
The upper spheroid 26a of the upper rotator 26 and the culm threshing between the lower spheroid 27a of the lower rotator 27 are sandwiched, and the kernel is sandwiched, so that only the kernel is degranulated, It is a configuration that is threshing
In the lower part of the threshing chamber 3, a threshing net 8 through which threshing products leak is stretched under the outer periphery of the lower threshing body 27a of the lower rotating body 27. Further, a rocking sorter 16 and a blower 17 are provided below the threshing net 8. The front of the threshing machine 1 is provided with an upper holding rod 14 for holding the culm and transporting the inside of the threshing chamber 3, and a feed chain 6 on the lower side.
[0051]
Thus, since the upper and lower rotating bodies 26 and 27 are used to shed only the grains of the culm to be threshed by the upper and lower shedding bodies 26a and 27a, the sorting is easy and the sorting performance is improved. In addition, the loss of shedding is reduced.
The threshing net 8 divides the mesh into four types: dense (a), slightly dense (b), ordinary (c), and rough (d), as shown in FIG. The threshing net 8 is formed by assembling. These meshes are configured such that eight types of combinations (a) to (j) are formed as shown in FIG. The threshing product threshed in the threshing room 8 has a configuration in which the leakage rate increases in the order of (a) to (j).
[0052]
Evaluation items such as grain culms to be threshed by the threshing machine 1 and the evaluation score are, as shown in FIG. 14, rice and wheat of the grain type, the moisture state of the grain, the weed mixed state, and the formation of the grain. It is a configuration for evaluating the condition. In addition, the evaluation score is configured to be evaluated based on a score of 1 or 2 points and a score of 1 to 3 points.
[0053]
For example, as shown in FIG. 15, when the type of grain is wheat grain, the grain moisture state is normal, the weed state is normal, and the grain is good, the evaluation score is 1 point. Two points, two points, and three points, the total point is eight points, and when the total total point is eight, the combination of the threshing net 8 is configured to select (e). If the total number of points is four, the combination of the threshing net 8 selects (a). When the total number of points is 12, the combination of the threshing net 8 is configured to select (j).
[0054]
Thereby, the combination of the meshes of the threshing net 8 can be selected according to the type of threshing to be threshed, moisture, weeds, condition, and the like, so that the condition adaptability can be improved. In addition, the sorting performance can be improved.
