Description

本発明は、茎葉を収穫する茎葉収穫機に関するものである。   The present invention relates to a foliage harvester that harvests foliage.

従来の茎葉処理機として、特許文献1に示されるように、接地部材を圃場に接地させて引起こし装置を圃場の起伏に合わせて上下動させるものがある。
また、特許文献2に示されるように、茎葉の搬送装置の前部に分草装置を備えるものがある。
As a conventional foliage processing machine, as shown in Patent Document 1, there is an apparatus in which a grounding member is grounded on a field and raised to move the apparatus up and down in accordance with the ups and downs of the field.

特開2002−253019号公報JP 2002-253019 A 特開2005−160467号公報JP 2005-160467 A

しかしながら、特許文献1及び2に記載される茎葉処理機には、処理した茎葉を搬送装置に掻き込む掻き込み手段を有さないため、処理した茎葉の量が多いと、搬送装置に茎葉が上手く入り込まず、茎葉が圃場に落下してしまい、作業者が手作業で拾い集めねばならず、作業者に余分な負担がかかる、という問題がある。   However, since the foliage processing machines described in Patent Documents 1 and 2 do not have a scraping means for scraping the processed foliage into the transport apparatus, if the amount of processed foliage is large, the foliage works well on the transport apparatus. There is a problem that the foliage falls into the field without entering, and the operator has to pick it up manually, which places an extra burden on the operator.

そして、特許文献1に記載される茎葉処理機は、引起こし装置の作業位置を機械的に上下動させる手段が設けられていないため、引起こし装置の作業位置を変更するときは機体の走行を停止させ、作業者が手作業で引起こし装置の作業位置を変更しなければならず、作業能率を低下させると共に作業者の労力を増加させてしまうという問題がある。   And since the foliage processing machine described in patent document 1 is not provided with the means to move up and down the working position of the raising device mechanically, when changing the working position of the raising device, the machine body travels. There is a problem that the operator must manually stop and raise the work position of the apparatus to reduce the work efficiency and increase the labor of the worker.

また、接地部材を圃場に接地させているだけであるため、小さな起伏に対しては反応しないことがあり、的確な作業位置調節がなされないという問題がある。
さらに、特許文献2に記載される茎葉処理機は、引起こし装置を茎葉の搬送装置の前部に備えているため、機体の走行等から生じる振動によって引起こし装置の作業位置が定まらないことがあり、適正な茎葉の引起こし作業に支障をきたすという問題がある。
In addition, since only the grounding member is grounded to the field, there is a problem that it may not respond to small undulations, and accurate work position adjustment is not performed.
Furthermore, since the foliage processing machine described in Patent Document 2 includes the raising device at the front part of the foliage conveying device, the working position of the raising device may not be determined by vibrations caused by the running of the machine. There is a problem in that it causes trouble in raising the appropriate foliage.

上記のように、フレーム6の左右前端下部に左右ステー24を、左右クローラ1L,1Rよりも前方に取り付けていることによって、左右ステー24の左右間に連結軸25を設けて左右ステー24を連結することができるので、機体の耐久性が強化される。   As described above, the left and right stays 24 are attached to the lower portions of the left and right front ends of the frame 6 in front of the left and right crawlers 1L and 1R. The durability of the aircraft is enhanced.

また、左右ステー24や連結軸25が刈取装置Eよりも上方に取り付けられていることによって、左右ステー24や連結軸25が畦や茎葉の刈り株に接触して機体の走行を妨げることを防止できるので、作業能率が向上する。   Further, since the left and right stays 24 and the connecting shaft 25 are attached above the cutting device E, the left and right stays 24 and the connecting shaft 25 are prevented from coming into contact with the bushes and foliage and preventing the aircraft from traveling. As a result, work efficiency is improved.

また、機体の走行による振動等の影響を受けにくいフレーム6の左右前側下部に取り付けた左右ステー24の左右間に連結軸25を取り付けると共に、該連結軸25に左右引起こし装置42を前端部に備えた左右回動アーム26を取り付けたことによって、左右引起こし装置42もまた機体の走行による振動等の影響を受けにくくなるので、左右引起こし装置42の作業位置を安定させることができ、作業能率が向上する。   In addition, a connecting shaft 25 is attached between the left and right of the left and right stays 24 attached to the lower left and right front lower portions of the frame 6 which are not easily affected by vibrations caused by the traveling of the airframe, and the left and right raising device 42 is attached to the connecting shaft 25 at the front end. By attaching the left / right pivot arm 26 provided, the left / right pulling device 42 is also less susceptible to vibrations caused by running of the airframe, so that the working position of the left / right pulling device 42 can be stabilized, Efficiency is improved.

さらに、左右回動アーム26が左右バランススプリング30によって上動方向に付勢されていると共に、左右引起こし装置42の下部に左右橇体36が取り付けられていることによって、左右引起こし装置42は圃場の起伏に応じて自由に上下動して、左右引起こし装置42の作業位置が適正になるので、作業能率が向上する。   Furthermore, the left and right pivoting device 42 is biased in the upward movement direction by the left and right balance spring 30 and the left and right casing 36 is attached to the lower part of the left and right pulling device 42. As the working position of the left and right pulling device 42 becomes appropriate according to the ups and downs of the field, the working efficiency is improved.

そして、左右回動アーム26が、左右各々独立して上下方向に回動自在に取り付けられていることによって、左右引起こし装置42は左右各々圃場の起伏に応じて自由に上下動して、左右引起こし装置42の左右各々の作業位置が適正になるので、作業能率が向上する。   The left and right pivoting arm 26 is attached to the left and right independently so as to be pivotable in the vertical direction, so that the left and right pulling device 42 freely moves up and down according to the undulation of the left and right fields, Since the right and left work positions of the pulling device 42 are appropriate, the work efficiency is improved.

また、左右橇体36は機体後外側方向に延出させられていることによって、畝に敷設したマルチを傷つけることなく左右引起し装置42を畝に近づけることができるので、茎葉の引起しが効率よく行われ作業能率が向上すると共に、後端部を上方に折り曲げていることによって、機体を後退させるときに左右橇体36の後端部が圃場に刺さって機体の後退を妨げる事が防止され、作業能率が向上する。   Further, since the left and right frame 36 is extended in the outward direction from the rear of the machine body, the left and right frame 36 can be brought close to the frame without damaging the mulch laid on the frame. The work efficiency is often improved and the rear end is bent upward, so that the rear end of the left and right frame 36 is prevented from being stuck in the field when the body is retracted, preventing the body from being retracted. , Work efficiency is improved.

そして、左右回動アーム26と左右リンクアーム28とが遊動機能を有する左右ワイヤー66によって連結されていることによって、昇降レバー19a,19bを操作して左右シリンダ31を伸縮させて左右リンクアーム28を上下動させると左右回動アーム26が左右ワイヤー66によって上下動させられるので、左右引起こし装置42の作業位置を圃場条件等に合わせて調節することができ、作業能率が向上する。   The left and right pivot arm 26 and the left and right link arm 28 are connected by a left and right wire 66 having a floating function, so that the left and right cylinders 31 are expanded and contracted by operating the elevating levers 19a and 19b. When moved up and down, the left and right turning arm 26 is moved up and down by the left and right wires 66, so that the work position of the left and right pulling device 42 can be adjusted according to the field conditions and the work efficiency is improved.

さらに、左右回動アーム26と左右リンクアーム28とが遊動機能を有する左右ワイヤー66によって連結されていることによって、左右引起こし装置42が圃場の起伏に合わせて自由に上下動するので、左右引起こし装置42の作業位置が適正になり、作業能率が向上する。   Further, since the left and right pivot arm 26 and the left and right link arm 28 are connected by a left and right wire 66 having a floating function, the left and right pulling device 42 freely moves up and down in accordance with the undulations of the field. The work position of the raising device 42 becomes appropriate, and the work efficiency is improved.

また、左右掻き上げ装置49が左右引起し装置42に連結されていることによって、左右引起し装置42の作業位置が変わると、左右掻き上げ装置49の作業位置も連動して変わり、掻き込み装置74への茎葉の掻き上げ効率が変化しにくいので、作業能率を安定させることができる。   Further, since the left and right scraping device 49 is connected to the left and right pulling device 42, when the working position of the left and right lifting device 42 changes, the working position of the left and right scraping device 49 also changes in conjunction with the scraping device. Since the scraping efficiency of the foliage to 74 hardly changes, the work efficiency can be stabilized.

そして、左右掻き上げ装置49の上端部の左右間隔が、下端部の左右間隔と略同一または下端部の左右間隔よりも上端部の左右間隔の方が広くなるように設けられていることによって、左右掻き上げ装置49の後部上端で茎葉が詰まって搬送装置Fに落下しなくなることが防止されるので、作業能率が向上する。   And the left and right spacing of the upper end of the left and right scraping device 49 is substantially the same as the left and right spacing of the lower end, or the left and right spacing of the upper end is wider than the left and right spacing of the lower end. Since it is prevented that the foliage is clogged at the upper end of the rear part of the left and right scraping device 49 and does not fall on the conveying device F, the work efficiency is improved.

さらに、左右案内ガイド32は、その後端部が機体外側方向に向けて開放されていると共に、搬送装置Fの上方且つ機体後方に向けて後上り傾斜姿勢に設けていることによって、茎葉を搬送装置F上に載るように誘導することができるので、圃場に落下する茎葉が少なくなり、圃場に落ちた茎葉を回収する作業が省略されて作業者の労力が軽減されると共に、左右案内部材32の終端部に茎葉が詰まることが防止でき、作業能率が向上する。   Further, the left and right guide guides 32 have rear end portions thereof opened toward the outer side of the machine body, and are provided in a rearward-upward inclined posture above the transfer apparatus F and toward the rear of the machine body. Since it can be guided so as to be placed on F, the number of fallen leaves is reduced, the work of collecting the fallen leaves on the field is omitted, and the labor of the operator is reduced. The end portion can be prevented from clogging with foliage and work efficiency can be improved.

また、搬送装置Fの搬送始端部上方且つ左右引起し装置42の間に掻き込み装置74が設けられていることによって、刈取装置Eで刈り取られた茎葉が搬送装置Fに掻き込まれるため、刈り取られた茎葉が搬送装置Fに載り易くなり、圃場に落下する茎葉が少なくなるため作業能率が向上すると共に、茎葉の回収作業が省略されるため作業者の労力を軽減することができる。   Further, since the scraping device 74 is provided above the transport start end of the transport device F and between the left and right pulling devices 42, the leaves and leaves cut by the reaping device E are scraped into the transport device F. The resulting foliage can be easily placed on the conveying device F, and the number of foliage falling on the field is reduced, so that the work efficiency is improved and the work of collecting the foliage is omitted, so that the labor of the operator can be reduced.
