Description

本発明は、農作物として玉葱が畝に栽培され、その玉葱を引き抜いて、茎葉部の基部を切断し、玉部は畝上に放出し、茎葉部は畝と畝の間の溝に排出する農作物収穫機において、切断後に移送装置後部から側方へ排出する茎葉部が排葉途中で堆積することなく畝間に確実に落下させる技術に関する。   The present invention is a crop in which an onion is cultivated in a cocoon as an agricultural product, the onion is pulled out, a base part of a foliage part is cut, a ball part is released onto the cocoon, and a foliage part is discharged into a groove between the cocoon and the cocoon. In a harvesting machine, the present invention relates to a technique for surely dropping a foliage portion discharged from a rear portion of a transfer device to a side after cutting without being deposited in the middle of the leaf discharge.

従来、歩行型の玉葱収穫機を用いて、畝に栽培された玉葱を掘り上げて引き抜き、茎葉部を挟持して後上方へ搬送しながら茎葉部の基部を切断し、玉葱の玉部は畝上に放出し、茎葉部は畝と畝の間の溝に排出するようにする技術は公知となっている。そして、切断後に排出される茎葉部が、ファイナルケース等に引っ掛かったり堆積したりしないように、機体の作業部と車輪との間へ案内するガイド板（流葉動体）を設ける技術が公知となっている（例えば、特許文献１参照）。
また、駆動車輪の車軸を機体内側へ延設して、この車軸上に排葉案内デイスクを固定して、畝溝へ案内する技術も公知となっている（例えば、特許文献２参照）。 Conventionally, using a walking-type onion harvester, the onion cultivated on the straw is dug up and pulled out, and the base of the stem and leaves is cut while pinching the foliage and transporting it upwards. A technique is known in which it is discharged upward and the foliage is discharged into a groove between the ridges. And the technique which provides the guide board (flow leaf moving body) which guides between the working part of an airframe and a wheel so that the foliage part discharged after cutting may not be caught or deposited on a final case etc. is known. (For example, refer to Patent Document 1).
In addition, a technique is also known in which an axle of a drive wheel is extended to the inside of the machine body, and a leaf guide disk is fixed on the axle and guided to a ridge (for example, see Patent Document 2).

しかし、前記技術において、玉葱の収穫量が多い場合や、茎葉部のボリュームが大きい場合や、湿り気が多い場合等においては、移送装置の終端からの排葉が、ガイド棒による案内後の自然落下だけでは、ガイド板の途中で滞留するおそれがあり、滞留が生じると人手により落下させる作業が必要であり、手間がかかり、更に、畝間に落ちた排葉は塊りとなって、車輪が通過する時にその塊りに乗り上げて機体の左右一側が上昇して、掘り上げ精度が低下することがあった。また、茎葉部を強制的に落下させるには別に落下させる装置が必要となり、構造が複雑となりコストアップにもなっていた。   However, in the above technique, when the yield of onions is large, when the volume of the foliage is large, or when there is a lot of moisture, the leaf leaves from the end of the transfer device are naturally dropped after being guided by the guide rod. Alone, there is a risk of staying in the middle of the guide plate. If staying occurs, it is necessary to manually drop it, which takes time, and the fallen leaves that fall between the traps become a lump and the wheel passes. When doing so, the left and right sides of the fuselage climbed on the lump, and the accuracy of digging was sometimes reduced. Further, in order to forcibly drop the foliage part, a separate dropping device is required, which complicates the structure and increases the cost.

本発明は以上の如き状況に鑑みてなされたものであり、農作物収穫機において、移送装置の送り終端から機体左右一側で、一方の駆動車輪に向けて茎葉部を放出する搬送経路を形成するガイド装置を設け、ガイド装置の終端位置が左右方向で駆動車輪位置とした構造とし、上記不具合を解消しようとする。これにより、排葉の放出に格別な装置を設けることなく、確実に切断後の茎葉部を圃場面に排出できるので、作業精度・作業能率が向上する。   The present invention has been made in view of the situation as described above, and in a crop harvesting machine, a conveyance path for discharging a foliage part toward one drive wheel is formed on the left and right sides of the machine body from the feed terminal of the transfer device. A guide device is provided, and the end position of the guide device is set to be a drive wheel position in the left-right direction, and the above-described problems are to be solved. Thereby, since the cut foliage part can be reliably discharged | emitted to a field scene, without providing a special apparatus for discharge | release of discharged leaves, work precision and work efficiency improve.

本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。
即ち、請求項１においては、畝溝を走行する左右の駆動車輪と、茎葉部を挟持して圃場から作物を引き抜き搬送する移送装置と、移送装置で茎葉部を挟持した状態で作物を切り離す切断装置とを備えた収穫機において、移送装置の送り終端から機体左右一側の駆動車輪に向けて茎葉部を放出する搬送経路を形成するガイド装置を設け、ガイド装置の終端位置が左右方向で駆動車輪の内側面近傍としたものである。 The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.
That is, in claim 1, the left and right drive wheels that run in the groin, the transfer device that holds the foliage part and pulls out the crop from the field, and the cutting that cuts the crop while holding the foliage part by the transfer device In a harvesting machine equipped with a device, a guide device is provided that forms a conveyance path that discharges the foliage from the feed end of the transfer device toward the drive wheel on the left and right sides of the machine body, and the end position of the guide device is driven in the left-right direction It is the vicinity of the inner surface of the wheel.

請求項２においては、前記ガイド装置の終端位置が、側面視で駆動車輪の外径位置で、駆動車輪の回転中心よりも前上方としたものである。   According to a second aspect of the present invention, the end position of the guide device is an outer diameter position of the drive wheel in a side view, and is located in front of and above the rotation center of the drive wheel.

請求項３においては、少なくともガイド装置が設けられる側の駆動車輪は、外周にラグが設けられるものである。
請求項４においては、前記ガイド装置の終端は、駆動車輪に対して高さ調節可能に構成されるものである。 According to a third aspect of the present invention, at least the drive wheel on the side where the guide device is provided is provided with a lug on the outer periphery.

以上のように、ガイド装置の終端位置が左右方向で駆動車輪の内側面近傍に配置されるので、切断後の茎葉部が駆動車輪まで案内されて駆動車輪の外周に接触し、機体の前進に伴う駆動車輪の回転により、茎葉部が圃場面まで引き込まれ、茎葉部が排葉途中で滞留することを防止できる。また、圃場に引き込まれた茎葉部は、畝溝に落下することになり、その上を駆動輪が通過し、茎葉部は圧縮されて減容積され、伝動ケースや車軸と干渉することが避けられ、オペレータが歩行する際にも邪魔にならない。
また、ガイド装置により案内された茎葉部は、駆動車輪上に載せられることになり、駆動車輪の前進回転により効率よく畝溝まで搬送することができる。そして、駆動車輪の外周にはラグが設けられているので、茎葉部を確実に搬送することができ、畝溝に落下した茎葉部は、面圧の高いラグにより押し潰されて、減容積化を容易に行える。 As described above, the end position of the guide device is arranged near the inner side surface of the drive wheel in the left-right direction, so that the cut foliage is guided to the drive wheel and contacts the outer periphery of the drive wheel to advance the aircraft. By the accompanying rotation of the driving wheel, the foliage part is drawn into the field scene, and the foliage part can be prevented from staying in the middle of the defoliation. In addition, the foliage drawn into the field will fall into the trough, the drive wheel passes over it, the foliage is compressed and reduced in volume, and it is possible to avoid interference with the transmission case and axle. The operator does not get in the way when walking.
Moreover, the foliage guided by the guide device is placed on the drive wheel, and can be efficiently conveyed to the ridge by the forward rotation of the drive wheel. And since the lug is provided on the outer periphery of the drive wheel, the foliage part can be reliably conveyed, and the foliage part that has fallen into the ridge groove is crushed by the lug with high surface pressure to reduce the volume. Can be easily performed.

The space between the drawing belt 21 and the drive wheel 9 is covered. Thus, the guide device 30 guides the foliage portion 6 a from the foliage discharge device 26 to the front upper side of the drive wheel 9. Then, soil and shards of the foliage spilled from the guide device 30 enter the ball transport device 24 and the foliage cutting device 25 by the front cover 28 and the rear cover 29 and do not get entangled with the axle drive case 7. ing.

前記ガイド装置３０は、移送装置２０の後部の茎葉放出装置２６の外側方（左方）から前下がりで玉部搬送装置２４の側方の車軸駆動ケース７前端より前方の上方まで延設される。ガイド装置３０はゴム等の弾性体で略四角形状の板体で構成され、後部右側に切欠３０ａが形成されて始端部とし、前左下部の角部を終端位置３０ｂとしている。   The guide device 30 extends from the outer side (left side) of the foliage discharge device 26 at the rear of the transfer device 20 to the front and above from the front end of the axle drive case 7 on the side of the ball transport device 24. . The guide device 30 is made of an elastic body such as rubber and is formed of a substantially quadrangular plate. A notch 30a is formed on the right side of the rear portion as a start end portion, and a corner portion at the lower left front portion is set as the end position 30b.

前記切欠３０ａは移送装置２０の後部下方の下カバー３４の側部に嵌合するように配置している。下カバー３４は左右の操縦ハンドル１３の前部間に架設して、エンジン３やミッションケース４の上方を覆うとともに、移送装置２０の後部下方に位置して、土や葉切れや塵埃等がエンジン３やミッションケース４や動力伝達系にかからないようにしている。こうして、ガイド装置３０の後部内側（右側）の切欠３０ａが茎葉放出装置２６よりも下方に位置し、ガイド装置３０の後部外側（左側）が移送装置２０の後部の下カバー３４よりも低い位置となるように配置することができる。従って、移送装置２０の後部から茎葉放出装置２６により側方へ搬送される茎葉部６ａがガイド装置３０に引っ掛かることなくガイド装置３０の後部上に載ることになる。   The notch 30a is disposed so as to be fitted to a side portion of the lower cover 34 below the rear portion of the transfer device 20. The lower cover 34 is installed between the front parts of the left and right control handles 13 to cover the upper part of the engine 3 and the transmission case 4 and is located below the rear part of the transfer device 20 so that dirt, leaf breaks, dust, etc. 3 and the mission case 4 and the power transmission system. Thus, the notch 30a on the rear inner side (right side) of the guide device 30 is positioned below the foliage discharge device 26, and the rear outer side (left side) of the guide device 30 is lower than the lower cover 34 on the rear portion of the transfer device 20. Can be arranged as follows. Accordingly, the foliage portion 6 a conveyed laterally from the rear portion of the transfer device 20 by the foliage discharge device 26 is placed on the rear portion of the guide device 30 without being caught by the guide device 30.

そして、ガイド装置３０は後部の切欠３０ａ近傍と前部外側（左側）の終端位置３０ｂ近傍が固定され、ガイド装置３０の前部機体左右中央側（右側）が前記揺動ロッド４１の前後方向中途部上に載置して配設され、前部右側端は移送装置２０の下方に延設される。こうして、振動ブレード２３が振動されると同時に、揺動ロッド４１に載るガイド装置３０の前右側が揺動されて振動が与えられ、排出される茎葉部６ａがガイド装置３０に載ると、前左下がりの傾斜により滑り落ち、前左下方への移動が前記振動により促進されることになる。   The guide device 30 is fixed in the vicinity of the rear notch 30a and the front outer side (left side) end position 30b, and the front body left and right center side (right side) of the guide device 30 is halfway in the front-rear direction of the swing rod 41. The front right end extends below the transfer device 20. Thus, at the same time as the vibration blade 23 is vibrated, the front right side of the guide device 30 placed on the rocking rod 41 is swung to give vibration, and when the discharged foliage portion 6a is placed on the guide device 30, the front left Sliding down due to the downward slope, the movement to the lower left front is promoted by the vibration.

ガイド装置３０の後部の切欠３０ａ近傍がボルト等により走行機体２に固定されており、本実施形態では、前記動力伝達ケース１４の左端に配置した偏心軸４０を覆うカバー４２の上面に固定される。また、ガイド装置３０の前左側は、ガイド装置３０及び駆動車輪９を外した図７に示すように、車軸駆動ケース７の前部に固定される支持部材に取り付けられる。支持部材は支持ステー３１と支持杆３２と上下調節板３３からなり、支持杆３２は棒材を逆Ｕ字状に折り曲げられ、該支持杆３２の前下部と後下部に上下調節手段としての上下調節板３３ａ・３３ｂが固定される。支持ステー３１は支持杆３２の上部の前下がりの部分に固定される。支持ステー３１に適宜固定孔が開口され、ガイド装置３０をネジ等で固定できるようにしている。   The vicinity of the notch 30a at the rear portion of the guide device 30 is fixed to the traveling machine body 2 by bolts or the like. In this embodiment, the guide device 30 is fixed to the upper surface of the cover 42 that covers the eccentric shaft 40 disposed at the left end of the power transmission case 14. . The front left side of the guide device 30 is attached to a support member fixed to the front portion of the axle drive case 7 as shown in FIG. 7 with the guide device 30 and the drive wheel 9 removed. The support member includes a support stay 31, a support rod 32, and an up / down adjustment plate 33. The support rod 32 is formed by bending a bar material in an inverted U shape. Adjustment plates 33a and 33b are fixed. The support stay 31 is fixed to the front lower part of the upper portion of the support rod 32. A fixing hole is appropriately opened in the support stay 31 so that the guide device 30 can be fixed with a screw or the like.

前記支持杆３２の前下部に固定した上下調節板３３ａは車軸駆動ケース７の前端に固定され、支持杆３２の後下部に固定した上下調節板３３ｂは車軸駆動ケース７の前上部に固定される。上下調節板３３ａ・３３ｂにはそれぞれ上下方向に長い長孔３２ｃ・３３ｄが開口され、該長孔３２ｃ・３３ｄにボルトを挿通して車軸駆動ケース７に位置調整可能に固定できるようにしている。こうして、ガイド装置３０の前外側端の高さを変更可能としている。この上下調節手段により、農作物収穫機１の作業時に車高を畝の高さに合わせて変更したときに、車軸駆動ケース７前端が上下に回動してもガイド装置３０の茎葉放出装置２６に対する上下位置が変わらないように、ガイド装置３０の前部の高さも変更するようにしている。この車高の変更時にガイド装置３０の高さも変更することで、ガイド装置３０の終端位置３０ｂの傾斜を略一定として排出される茎葉部６ａが滞留することを防止できるようにしている。   A vertical adjustment plate 33 a fixed to the front lower portion of the support rod 32 is fixed to the front end of the axle drive case 7, and a vertical adjustment plate 33 b fixed to the rear lower portion of the support rod 32 is fixed to the front upper portion of the axle drive case 7. . Long vertical holes 32c and 33d are opened in the vertical adjustment plates 33a and 33b, respectively. Bolts are inserted into the long holes 32c and 33d so that the vertical adjustment plates 33a and 33b can be fixed to the axle drive case 7 so that the position can be adjusted. In this way, the height of the front outer end of the guide device 30 can be changed. By this vertical adjustment means, when the vehicle height is changed in accordance with the height of the ridge during the operation of the crop harvesting machine 1, even if the front end of the axle drive case 7 is rotated up and down, the foliage discharge device 26 of the guide device 30 is controlled. The height of the front part of the guide device 30 is also changed so that the vertical position does not change. By changing the height of the guide device 30 at the time of changing the vehicle height, it is possible to prevent the stems and leaves 6a to be discharged from staying with the inclination of the terminal position 30b of the guide device 30 being substantially constant.

そして、ガイド装置３０の後端の高さは移送装置２０の後端よりも低く、駆動車輪９の上端よりも高い位置としている。ガイド装置３０の前端の終端位置３０ｂは、図５に示すように、側面視で駆動車輪９の外径位置近傍（外周近傍）で、駆動車輪９の車軸中心よりも前上方としている。言い換えれば、ガイド装置３０の終端位置３０ｂは駆動車輪９の前上部の外周の接線方向となるように延設している。   The height of the rear end of the guide device 30 is lower than the rear end of the transfer device 20 and higher than the upper end of the drive wheel 9. As shown in FIG. 5, the end position 30b at the front end of the guide device 30 is near the outer diameter position (near the outer periphery) of the drive wheel 9 in a side view, and is front-upward from the axle center of the drive wheel 9. In other words, the terminal position 30 b of the guide device 30 extends so as to be in the tangential direction of the outer periphery of the front upper portion of the drive wheel 9.

ガイド装置３０の終端位置３０ｂが左右方向で駆動車輪９の内側面近傍となるように配置している。即ち、ガイド装置３０の左端は、図３に示すように、左側の車軸駆動ケース７の左端の面と略同じ位置としている。言い換えれば、ガイド装置３０の左端は、左側の駆動車輪９の内側面と所定の隙間が生じる程度に接近して配置される。この隙間は茎葉部６ａがこの隙間から落下しない程度である。   It arrange | positions so that the terminal position 30b of the guide apparatus 30 may become the inner surface side vicinity of the drive wheel 9 in the left-right direction. That is, as shown in FIG. 3, the left end of the guide device 30 is set substantially at the same position as the left end surface of the left axle drive case 7. In other words, the left end of the guide device 30 is disposed so as to be close to the inner surface of the left drive wheel 9 so that a predetermined gap is generated. This gap is such that the foliage portion 6a does not fall from this gap.

また、前記駆動車輪９の外周にはラグ９ａが設けられており、走行時におけるグリップ力を高めてスリップを防止して走行性能を高めるとともに、駆動車輪９の上部に落下してきた茎葉部６ａを農作物収穫機１の前進に伴う駆動車輪９の前進回転により前方へ落下させる。つまり、駆動車輪９の外周には所定間隔をあけて所定高さの突起を形成したラグ９ａ・９ａ・・・が形成され、収穫作業時に茎葉放出装置２６からガイド装置３０に載った茎葉部６ａは終端位置３０ｂ近傍で駆動車輪９上に載り、駆動車輪９の前進回転により、外周に形成したラグ９ａが前方への送り作用を果たし、茎葉部６ａは滞留することがなく畝溝に落下するようになる。   A lug 9a is provided on the outer periphery of the drive wheel 9 to increase the grip force during travel to prevent slipping and improve travel performance. It is dropped forward by the forward rotation of the drive wheel 9 accompanying the advance of the crop harvesting machine 1. That is, lugs 9a, 9a... Having protrusions with a predetermined height are formed on the outer periphery of the drive wheel 9, and the foliage portion 6a mounted on the guide device 30 from the foliage discharge device 26 during the harvesting operation. Is placed on the drive wheel 9 in the vicinity of the end position 30b, and by the forward rotation of the drive wheel 9, the lug 9a formed on the outer periphery performs the forward feeding action, and the foliage portion 6a falls into the ridge groove without staying. It becomes like this.

以上のように、畝溝を走行する左右の駆動車輪９・９と、茎葉部６ａを挟持して圃場から作物を引き抜き搬送する移送装置２０と、移送装置２０で茎葉部６ａを挟持した状態で作物を切り離す切断装置２５とを備えた農作物収穫機１において、移送装置２０の送り終端から機体左右一側の駆動車輪９に向けて茎葉部６ａを放出する搬送経路を形成するガイド装置３０を設け、ガイド装置３０の終端位置３０ｂが左右方向で駆動車輪９の内側面近傍としたので、切断後の茎葉部６ａが駆動車輪９まで案内されて駆動車輪９の外周に接触し、機体の前進に伴う駆動車輪９の回転により、茎葉部６ａが圃場面まで引き込まれ、茎葉部６ａが排葉途中で滞留することを防止できる。従って、茎葉部６ａが塊りとなって畝溝に落ちることがなくなり、塊りに駆動車輪９が乗り上げて機体が傾斜して収穫精度が悪化することもなくなる。そして、畝溝に落ちた茎葉部６ａはその上を通過する駆動車輪９により踏まれて圧縮され、減容積となり、茎葉部６ａが広がったままで車軸駆動ケース７や車軸８と干渉することを避けられる。作業者が歩行する際にも茎葉部６ａは減容積されているので邪魔にならなくなる。   As described above, the left and right drive wheels 9 and 9 that run in the ridge groove, the transfer device 20 that pulls and conveys the crop from the field by holding the foliage portion 6a, and the foliage portion 6a that is held by the transfer device 20 In the crop harvesting machine 1 provided with the cutting device 25 for cutting off the crop, a guide device 30 is provided that forms a conveyance path for discharging the foliage portion 6a from the feed terminal of the transfer device 20 toward the drive wheel 9 on the left and right sides of the machine body. Since the terminal position 30b of the guide device 30 is in the vicinity of the inner surface of the drive wheel 9 in the left-right direction, the cut leaves and leaves 6a are guided to the drive wheel 9 and come into contact with the outer periphery of the drive wheel 9 to advance the airframe. By the accompanying rotation of the drive wheel 9, the foliage portion 6a is drawn into the field scene, and the foliage portion 6a can be prevented from staying in the middle of leaf discharge. Therefore, the foliage portion 6a does not become a lump and falls into the trough, and the driving wheel 9 rides on the lump, and the machine body is inclined and the harvesting accuracy is not deteriorated. Then, the foliage portion 6a that has fallen into the groin is stepped on and compressed by the drive wheel 9 that passes over it, reducing the volume, and avoiding interference with the axle drive case 7 and the axle 8 while the foliage portion 6a is spread. It is done. Even when the worker walks, the foliage portion 6a is reduced in volume so that it does not get in the way.

また、前記ガイド装置３０の終端位置３０ｂが、側面視で駆動車輪９の外径位置で、駆動車輪９の回転中心よりも前上方としたので、茎葉放出装置２６から排出された茎葉部６ａはガイド装置３０の終端位置３０ｂから駆動車輪９に載って、或いは、誘導されて、圃場に引き込まれて畝溝に落下することになり、茎葉放出装置２６から強制的に搬送する装置を設ける必要がなく、農作物収穫機１が備える駆動車輪９が茎葉物を搬送することになり、効率良く茎葉部を搬送できるようになる。   Further, since the terminal position 30b of the guide device 30 is the outer diameter position of the drive wheel 9 in a side view and is located in front of and above the rotation center of the drive wheel 9, the foliage portion 6a discharged from the foliage discharge device 26 is It is necessary to provide a device that forcibly conveys from the foliage discharge device 26 because it is placed on the driving wheel 9 from the terminal position 30b of the guide device 30 or is guided to be drawn into the field and falls into the ridge. In addition, the drive wheels 9 included in the crop harvesting machine 1 will transport the foliage, so that the foliage can be efficiently conveyed.

また、少なくともガイド装置３０が設けられる側の駆動車輪９は、外周にラグ９ａが設けられるので、ラグ９ａが茎葉部６ａを畝間へ引き込む作用を有するようになり、湿った茎葉部や降雨後の作業等の場合であっても、茎葉部６ａを停滞することなく畝溝へ確実に搬送することができる。そして、茎葉部６ａが落下した後の畝溝を走行する際にも、ラグなしではスリップするおそれがあるが、駆動車輪９の外周にはラグ９ａが設けられるので、グリップ力が高められ、確実に走行することができる。さらに、畝溝に落下した茎葉部６ａは、面圧の高いラグ９ａにより押し潰されて、減容積化が容易に行われる。   In addition, since at least the drive wheel 9 on the side where the guide device 30 is provided is provided with a lug 9a on the outer periphery, the lug 9a has an action of drawing the foliage 6a into the intercostal space. Even in the case of work or the like, the foliage portion 6a can be reliably conveyed to the groin without stagnation. And even when traveling in the ridge after the foliage 6a has fallen, there is a risk of slipping without a lug, but since the lug 9a is provided on the outer periphery of the drive wheel 9, the gripping force is increased and reliable. You can travel to. Furthermore, the foliage portion 6a that has fallen into the ridge groove is crushed by the lug 9a having a high surface pressure, and volume reduction is easily performed.

また、前記ガイド装置３０の終端側は、支持杆３２と上下調節板３３よりなる支持部材により支持され、該支持杆３２は上下調節手段を介して車軸駆動ケース７に支持されるので、ガイド装置３０の終端は駆動車輪９に対して高さ調節可能とされ、機体の高さを畝の高さに合わせて変更したときにガイド装置３０の終端位置を調節して、最適傾斜で、スムーズに茎葉部６ａを下方へ案内できる。   The terminal side of the guide device 30 is supported by a support member comprising a support rod 32 and a vertical adjustment plate 33, and the support rod 32 is supported by the axle drive case 7 via the vertical adjustment means. The end of 30 can be adjusted with respect to the driving wheel 9, and when the height of the fuselage is changed to match the height of the kite, the end position of the guide device 30 is adjusted to achieve the optimum inclination and smoothness. The foliage portion 6a can be guided downward.
