Description

本発明は、走行機体上に脱穀装置と穀粒回収部とが左右に並べて設けられ、前記脱穀装置を通過した処理物の排出口が前記脱穀装置の後端に形成されている普通型コンバインに関する。   The present invention relates to a normal combine in which a threshing device and a grain recovery unit are provided side by side on a traveling machine body, and a discharge port for a processed material that has passed through the threshing device is formed at a rear end of the threshing device. .

従来、この種の普通型コンバインとしては、前記脱穀装置の排出口は、走行機体の後方に張り出したカバーで覆われ、カバーの下方は開口する状態に形成されているものがあった(例えば、特許文献1参照)。
従って、脱穀装置から排出される稈等の処理物は、前記排出口から直接に地面に向けて落下していた。
Conventionally, as an ordinary combine of this type, the threshing device has a discharge port covered with a cover projecting behind the traveling machine body, and a lower part of the cover is formed in an open state (for example, Patent Document 1).
Therefore, the processed materials such as the rice cake discharged from the threshing device have been dropped directly toward the ground from the discharge port.

特開2010−22320号公報(段落番号0021,図1〜3)Japanese Patent Laying-Open No. 2010-22320 (paragraph number 0021, FIGS. 1 to 3)

コンバインによる植立穀稈の刈り取りは、未刈領域において走行機体を走行させることで、走行機体の前端に備えられた刈取前処理装置の刈取幅寸法内に位置する穀稈を順次刈りとるものである。刈取走行跡には、刈取前処理装置の刈取幅寸法の幅の帯状既刈領域が形成される。
この帯状既刈領域が、隣接状態に並列するようにコンバインの走行を繰り返すことで、圃場全域の刈り取りを完了することができる。
従って、効率よく刈り取りを行うには、隣接する帯状既刈領域どうしが可能な限り重ならないようにコンバインを走行させることが必要となる。
具体的には、前記刈取前処理装置の既刈領域側の端部に位置するデバイダが、前方に位置している植立穀稈の内、隣接する既刈領域側の端部に位置する植立穀稈の株元を目差すように刈取走行経路をとることが重要である。
The harvesting of the planted cereals by the combine is to move the traveling machine body in the uncut area and sequentially harvest the cereal grains that are located within the cutting width dimension of the cutting pretreatment device provided at the front end of the traveling machine body. is there. A band-like already cut region having a width of the cutting width dimension of the cutting pretreatment device is formed on the cutting running trace.
By repeating the traveling of the combine so that the strip-shaped already cut region is arranged in parallel with the adjacent state, the cutting of the entire field can be completed.
Therefore, in order to cut efficiently, it is necessary to run the combine so that adjacent strip-like cut areas do not overlap as much as possible.
Specifically, the divider located at the end of the pre-harvest area of the pre-cutting device is a planting plant located at the end of the adjacent harvested area among the planted cereals located in the front. It is important to take a cutting-running route so as to look at the stock of the cereal grain.

上述した従来の普通型コンバインによれば、前記排出口から落下する排稈等の処理物は、当該コンバインによって刈り込んだ圃場上に排出される際、排出口の下方範囲を含む周辺地盤上に散乱する状態で排出される。
従って、処理物は、圃場の既刈領域のみならず、隣接する未刈領域にも達し、植立穀稈の株元にも被さる状態に排出されることがある。
その結果、上述のようにコンバインを走行させるにあたり、端部に位置する植立穀稈の株元に処理物が被さっていて、その位置を確認しにくい。
また、植立穀稈の株元に処理物が被さっていると、コンバインの走行に伴ってデバイダに処理物が引っ掛かったまま引きずられ、刈取の障害になる問題もある。
According to the conventional ordinary combine described above, the processed material such as the waste falling from the discharge port is scattered on the surrounding ground including the lower range of the discharge port when discharged onto the field cut by the combine. It is discharged in the state to do.
Therefore, the processed product may reach not only the already cut area of the field but also the adjacent uncut area and be discharged in a state of covering the planted cereal stock.
As a result, when the combine is made to travel as described above, the processed material covers the planted cereal stock at the end, and it is difficult to confirm the position.
In addition, if the planted cereal stock is covered with a processed material, the processed material is dragged while being caught by the divider as the combine runs, and there is a problem that cutting becomes an obstacle.

従って、本発明の目的は、上記問題点を解消し、刈取走行経路に隣接する未刈領域に処理物が排出されにくくできる普通型コンバインを提供するところにある。   Accordingly, an object of the present invention is to provide a normal combine that solves the above-described problems and makes it difficult to discharge the processed material to an uncut region adjacent to the cutting travel route.

本発明は、走行機体上に脱穀装置と穀粒回収部とが左右に並べて設けられ、前記脱穀装置を通過した処理物の排出口が前記脱穀装置の後端に形成されている普通型コンバインであって、
前記排出口を後方から覆うカバーが設けてあり、
前記排出口の下方に、前記排出口から排出される処理物を、前記走行機体の幅方向での前記脱穀装置側から前記穀粒回収部側へ誘導して地面に落下させる誘導傾斜部が設けてあり、
背面視において、前記誘導傾斜部は、前記カバーのうち前記脱穀装置に対して前記穀粒回収部とは反対側に位置する側板部の下端部から下方に延びており、
前記誘導傾斜部の後方側に、上方に立ち上がる第一立ち上がり壁部が設けてあるものである。
The present invention is a normal combine in which a threshing device and a grain recovery unit are provided side by side on a traveling machine body, and a discharge port for a processed material that has passed through the threshing device is formed at a rear end of the threshing device. There,
A cover for covering the discharge port from the rear is provided;
Provided below the discharge port is a guide inclined portion that guides the processed material discharged from the discharge port from the threshing device side in the width direction of the traveling machine body to the grain recovery unit side and drops it to the ground. And
In the rear view, the guide inclined portion extends downward from the lower end portion of the side plate portion located on the opposite side of the grain recovery portion with respect to the threshing device of the cover,
A first rising wall portion that rises upward is provided on the rear side of the guide inclined portion.

本発明によれば、排出口から排出される処理物を、前記誘導傾斜部によって受けて、走行機体の幅方向での脱穀装置側から穀粒回収部側へ誘導して地面に落下させることができ、従来のように、処理物が、排出口から直接に地面に排出されるのに比べて、散乱しにくくできる。
また、コンバインの穀粒回収部側(一般には走行方向右側であることが多い)に既刈領域が位置し、脱穀装置側(一般には走行方向左側であることが多い)に未刈領域が位置するような配置環境下でコンバインの刈取走行を実施するような場合に、コンバインから排出される処理物は、既刈領域側に誘導され(以後、「処理物誘導作用」という)、未刈領域の植立穀稈の株元に被さり難くできるようになる。
その結果、刈取走行経路に隣接する未刈領域に処理物が排出されにくくなり、未刈領域の植立穀稈の株元を処理物が隠すことを防止できるようになる。よって、コンバインの前方の(特に植立穀稈の株元における)見通しをよくして、刈取走行経路の選択を行う上での判断を、より正確に実施できるようになる。
即ち、前記刈取前処理装置の既刈領域側の端部に位置するデバイダが、前方に位置している植立穀稈の内、隣接する既刈領域側の端部に位置する植立穀稈の株元を目差すように刈取走行経路をとりやすくなり、隣接する帯状既刈領域どうしが重ならないようにして、効率よく刈り取りを行うことが実現する。
更には、未刈領域の植立穀稈の株元に被さった処理物がデバイダに引っ掛かったまま引きずられることも防止でき、良好な状態での刈り取りを実現できる。
According to the onset bright, the treated product is discharged from the discharge port, and received by the guide inclined part, it is dropped to the ground from the threshing apparatus in the width direction of the vehicle body to guide the grain collecting portion Compared to the case where the processed material is discharged directly from the discharge port directly to the ground as in the conventional case, it is difficult to scatter.
In addition, the harvested area is located on the side of the combine grain recovery unit (generally on the right side in the running direction), and the uncut area is located on the threshing device side (generally on the left side in the running direction). When the harvesting of the combine is carried out in such an arrangement environment, the processed material discharged from the combine is guided to the already-cutted region side (hereinafter referred to as “processed material guiding action”), and the uncut region It becomes difficult to cover the planted grain cereal stock.
As a result, the processed material is less likely to be discharged to the uncut region adjacent to the cutting travel route, and the processed product can be prevented from concealing the stock of the planted cereal in the uncut region. Therefore, it is possible to improve the visibility in front of the combine (especially at the planting cereal stock) and to make a more accurate determination when selecting the cutting travel route.
That is, the divider located at the end of the pre-harvest region of the pre-harvest processing device is a planted culm located at the end of the adjacent reaped region among the planted culms located in the front. It becomes easy to take a cutting travel route so as to look at the stock of the plant, and it is realized that cutting is performed efficiently so that adjacent strip-shaped already cut areas do not overlap.
Furthermore, it is possible to prevent the processed material covered with the planted grain culm in the uncut region from being dragged while being caught by the divider, and it is possible to realize cutting in a good state.

上記構成において、前記誘導傾斜部は、前記カバーに対して脱穀装置とは反対側に設けてあり、前記カバーにおける前記穀粒回収部側の側面部分に、前記処理物を下方へ誘導する縦壁部を設けており、前記縦壁部を、前記カバーの後板部の下端部よりも下方に延出してあると好適である。The said structure WHEREIN: The said guidance inclination part is provided in the opposite side to the threshing apparatus with respect to the said cover, The vertical wall which guides the said processed material to the side part by the side of the said grain collection | recovery part in the said cover. It is preferable that the vertical wall portion extends downward from the lower end portion of the rear plate portion of the cover.
上記構成において、前記縦壁部は、その下縁部が、前記誘導傾斜部の傾斜面下端部より低くなるように形成してあると好適である。The said structure WHEREIN: It is suitable when the said vertical wall part is formed so that the lower edge part may become lower than the inclined surface lower end part of the said guidance inclination part.
本構成によれば、誘導傾斜部の傾斜面の延長上に縦壁部を位置させることができるから、処理物の下方への誘導効果をより向上させることができる。According to this configuration, since the vertical wall portion can be positioned on the extension of the inclined surface of the guiding inclined portion, it is possible to further improve the effect of guiding the processed material downward.

また、本発明は、走行機体上に脱穀装置と穀粒回収部とが左右に並べて設けられ、前記脱穀装置を通過した処理物の排出口が前記脱穀装置の後端に形成されている普通型コンバインであって、Further, the present invention is a normal type in which a threshing device and a grain recovery unit are arranged side by side on a traveling machine body, and a discharge port for a processed material that has passed through the threshing device is formed at a rear end of the threshing device. A combine,
前記排出口を後方から覆うカバーが設けてあり、A cover for covering the discharge port from the rear is provided;
前記排出口の下方に、前記排出口から排出される処理物を、前記走行機体の幅方向での前記脱穀装置側から前記穀粒回収部側へ誘導して地面に落下させる誘導傾斜部が設けてあり、Provided below the discharge port is a guide inclined portion that guides the processed material discharged from the discharge port from the threshing device side in the width direction of the traveling machine body to the grain recovery unit side and drops it to the ground. And
前記誘導傾斜部は、前記カバーに対して脱穀装置とは反対側に設けてあり、The guide slope is provided on the opposite side of the cover from the threshing device,
前記カバーの前記穀粒回収部側の側面部分に、前記処理物を下方へ誘導する縦壁部を設けており、A side wall portion of the cover on the side of the grain recovery unit is provided with a vertical wall portion that guides the processed product downward,
前記縦壁部は、その下縁部が、前記誘導傾斜部の傾斜面下端部より低くなるように形成してあるものである。The said vertical wall part is formed so that the lower edge part may become lower than the inclined surface lower end part of the said guidance inclined part.

本発明によれば、排出口から排出される処理物を、前記誘導傾斜部によって受けて、走行機体の幅方向での脱穀装置側から穀粒回収部側へ誘導して地面に落下させることができ、従来のように、処理物が、排出口から直接に地面に排出されるのに比べて、散乱しにくくできる。According to the present invention, the processed material discharged from the discharge port is received by the guiding inclined portion, guided from the threshing device side in the width direction of the traveling machine body to the grain collecting portion side, and dropped to the ground. As compared with the case where the processed material is discharged directly from the discharge port directly to the ground as in the conventional case, the processed material can be hardly scattered.
また、コンバインの穀粒回収部側(一般には走行方向右側であることが多い)に既刈領域が位置し、脱穀装置側(一般には走行方向左側であることが多い)に未刈領域が位置するような配置環境下でコンバインの刈取走行を実施するような場合に、コンバインから排出される処理物は、既刈領域側に誘導され(以後、「処理物誘導作用」という)、未刈領域の植立穀稈の株元に被さり難くできるようになる。In addition, the harvested area is located on the side of the combine grain recovery unit (generally on the right side in the running direction), and the uncut area is located on the threshing device side (generally on the left side in the running direction). When the harvesting of the combine is carried out in such an arrangement environment, the processed material discharged from the combine is guided to the already-cutted region side (hereinafter referred to as “processed material guiding action”), and the uncut region It becomes difficult to cover the planted grain cereal stock.
その結果、刈取走行経路に隣接する未刈領域に処理物が排出されにくくなり、未刈領域の植立穀稈の株元を処理物が隠すことを防止できるようになる。よって、コンバインの前方の(特に植立穀稈の株元における)見通しをよくして、刈取走行経路の選択を行う上での判断を、より正確に実施できるようになる。As a result, the processed material is less likely to be discharged to the uncut region adjacent to the cutting travel route, and the processed product can be prevented from concealing the stock of the planted cereal in the uncut region. Therefore, it is possible to improve the visibility in front of the combine (especially at the planting cereal stock) and to make a more accurate determination when selecting the cutting travel route.
即ち、前記刈取前処理装置の既刈領域側の端部に位置するデバイダが、前方に位置している植立穀稈の内、隣接する既刈領域側の端部に位置する植立穀稈の株元を目差すように刈取走行経路をとりやすくなり、隣接する帯状既刈領域どうしが重ならないようにして、効率よく刈り取りを行うことが実現する。That is, the divider located at the end of the pre-harvest region of the pre-harvest processing device is a planted culm located at the end of the adjacent reaped region among the planted culms located in the front. It becomes easy to take a cutting travel route so as to look at the stock of the plant, and it is realized that cutting is performed efficiently so that adjacent strip-shaped already cut areas do not overlap.
更には、未刈領域の植立穀稈の株元に被さった処理物がデバイダに引っ掛かったまま引きずられることも防止でき、良好な状態での刈り取りを実現できる。Furthermore, it is possible to prevent the processed material covered with the planted grain culm in the uncut region from being dragged while being caught by the divider, and it is possible to realize cutting in a good state.
加えて、誘導傾斜部の傾斜面に沿って落下する処理物を、前記縦壁部によって下方へ誘導することができるから、処理物が地面の広範囲に散乱するのを防止できる。更には、縦壁部の背面側に処理物が回り込むのを防止できるから、前記縦壁部の背面側に、例えば、各種機器やタンク等を配置しても処理物が被さるのを防止できる。In addition, since the processed material falling along the inclined surface of the guiding inclined portion can be guided downward by the vertical wall portion, the processed material can be prevented from being scattered over a wide range of the ground. Furthermore, since it is possible to prevent the processed material from entering the back side of the vertical wall portion, it is possible to prevent the processed material from being covered even if various devices, tanks, or the like are disposed on the back surface side of the vertical wall portion.
その上、誘導傾斜部の傾斜面の延長上に縦壁部を位置させることができるから、処理物の下方への誘導効果をより向上させることができる。In addition, since the vertical wall portion can be positioned on the extension of the inclined surface of the guiding inclined portion, the effect of guiding the processed material downward can be further improved.

また、本発明は、走行機体上に脱穀装置と穀粒回収部とが左右に並べて設けられ、前記脱穀装置を通過した処理物の排出口が前記脱穀装置の後端に形成されている普通型コンバインであって、Further, the present invention is a normal type in which a threshing device and a grain recovery unit are arranged side by side on a traveling machine body, and a discharge port for a processed material that has passed through the threshing device is formed at a rear end of the threshing device. A combine,
前記排出口の下方に、前記排出口から排出される処理物を、前記走行機体の幅方向での前記脱穀装置側から前記穀粒回収部側へ誘導して地面に落下させる誘導傾斜部が設けてあり、Provided below the discharge port is a guide inclined portion that guides the processed material discharged from the discharge port from the threshing device side in the width direction of the traveling machine body to the grain recovery unit side and drops it to the ground. And
前記誘導傾斜部の上空間から前記誘導傾斜部の前記穀粒回収部側に隣接する傾斜下流側空間を覆うカバーが設けてあり、A cover is provided to cover the inclined downstream space adjacent to the grain collection unit side of the guiding inclined portion from the upper space of the guiding inclined portion,
前記カバーには、少なくとも前記傾斜下流側空間の下方と後方が開口する開口部が設けてあり、The cover is provided with an opening that opens at least below and behind the inclined downstream space,
前記カバーにおける前記穀粒回収部側の側面部分は、前記処理物を下方へ誘導する縦壁部として構成してあり、The side part of the cover on the side of the grain recovery part is configured as a vertical wall part that guides the processed product downward,
前記縦壁部は、その下縁部が、前記誘導傾斜部の傾斜面下端部より低くなるように形成してあるものである。The said vertical wall part is formed so that the lower edge part may become lower than the inclined surface lower end part of the said guidance inclined part.

本発明によれば、排出口から排出される処理物を、前記誘導傾斜部によって受けて、走行機体の幅方向での脱穀装置側から穀粒回収部側へ誘導して地面に落下させることができ、従来のように、処理物が、排出口から直接に地面に排出されるのに比べて、散乱しにくくできる。According to the present invention, the processed material discharged from the discharge port is received by the guiding inclined portion, guided from the threshing device side in the width direction of the traveling machine body to the grain collecting portion side, and dropped to the ground. As compared with the case where the processed material is discharged directly from the discharge port directly to the ground as in the conventional case, the processed material can be hardly scattered.
また、コンバインの穀粒回収部側(一般には走行方向右側であることが多い)に既刈領域が位置し、脱穀装置側(一般には走行方向左側であることが多い)に未刈領域が位置するような配置環境下でコンバインの刈取走行を実施するような場合に、コンバインから排出される処理物は、既刈領域側に誘導され(以後、「処理物誘導作用」という)、未刈領域の植立穀稈の株元に被さり難くできるようになる。In addition, the harvested area is located on the side of the combine grain recovery unit (generally on the right side in the running direction), and the uncut area is located on the threshing device side (generally on the left side in the running direction). When the harvesting of the combine is carried out in such an arrangement environment, the processed material discharged from the combine is guided to the already-cutted region side (hereinafter referred to as “processed material guiding action”), and the uncut region It becomes difficult to cover the planted grain cereal stock.
その結果、刈取走行経路に隣接する未刈領域に処理物が排出されにくくなり、未刈領域の植立穀稈の株元を処理物が隠すことを防止できるようになる。よって、コンバインの前方の(特に植立穀稈の株元における)見通しをよくして、刈取走行経路の選択を行う上での判断を、より正確に実施できるようになる。As a result, the processed material is less likely to be discharged to the uncut region adjacent to the cutting travel route, and the processed product can be prevented from concealing the stock of the planted cereal in the uncut region. Therefore, it is possible to improve the visibility in front of the combine (especially at the planting cereal stock) and to make a more accurate determination when selecting the cutting travel route.
即ち、前記刈取前処理装置の既刈領域側の端部に位置するデバイダが、前方に位置している植立穀稈の内、隣接する既刈領域側の端部に位置する植立穀稈の株元を目差すように刈取走行経路をとりやすくなり、隣接する帯状既刈領域どうしが重ならないようにして、効率よく刈り取りを行うことが実現する。That is, the divider located at the end of the pre-harvest region of the pre-harvest processing device is a planted culm located at the end of the adjacent reaped region among the planted culms located in the front. It becomes easy to take a cutting travel route so as to look at the stock of the plant, and it is realized that cutting is performed efficiently so that adjacent strip-shaped already cut areas do not overlap.
更には、未刈領域の植立穀稈の株元に被さった処理物がデバイダに引っ掛かったまま引きずられることも防止でき、良好な状態での刈り取りを実現できる。Furthermore, it is possible to prevent the processed material covered with the planted grain culm in the uncut region from being dragged while being caught by the divider, and it is possible to realize cutting in a good state.
しかも、カバーによって、排出口から排出された処理物が周囲に散乱するのを防止できると共に、風や機体の揺れ等があってもより確実に前記処理物誘導作用を発揮できる。Moreover, the cover can prevent the processed material discharged from the discharge port from being scattered to the surroundings, and can more reliably exhibit the processed material inducing action even if there is wind or shaking of the machine body.
また、カバーの開口部を、少なくとも傾斜下流側空間の下方と後方に設けてあることで、処理物が詰まり難い状態を維持してスムースな排出を叶えることができ、更には、排出口の近隣のメンテナンス等の作業を、前記開口部を通して走行機体の後方側から実施することが可能となる。In addition, since the opening of the cover is provided at least below and behind the inclined downstream space, it is possible to achieve a smooth discharge while maintaining a state in which the processed material is not easily clogged. It is possible to perform operations such as maintenance from the rear side of the traveling machine body through the opening.
即ち、機能性とメンテナンス性の向上の両立化を図ることができる。That is, it is possible to achieve both improvement in functionality and maintenance.
加えて、誘導傾斜部の傾斜面に沿って落下する処理物を、前記縦壁部によって下方へ誘導することができるから、処理物が地面の広範囲に散乱するのを防止できる。更には、縦壁部の背面側に処理物が回り込むのを防止できるから、前記縦壁部の背面側に、例えば、各種機器やタンク等を配置しても処理物が被さるのを防止できる。In addition, since the processed material falling along the inclined surface of the guiding inclined portion can be guided downward by the vertical wall portion, the processed material can be prevented from being scattered over a wide range of the ground. Furthermore, since it is possible to prevent the processed material from entering the back side of the vertical wall portion, it is possible to prevent the processed material from being covered even if various devices, tanks, or the like are disposed on the back surface side of the vertical wall portion.
その上、誘導傾斜部の傾斜面の延長上に縦壁部を位置させることができるから、処理物の下方への誘導効果をより向上させることができる。In addition, since the vertical wall portion can be positioned on the extension of the inclined surface of the guiding inclined portion, the effect of guiding the processed material downward can be further improved.
