Description

本発明は根菜類の収穫機に装着するマルチシート回収装置に関するものである。   TECHNICAL FIELD The present invention relates to a multi-sheet collecting device to be mounted on a root vegetable harvesting machine.

圃場に敷設された農業用マルチシートは、葉物野菜等の栽培については、収穫後に回収して廃棄される。また根菜類の栽培に使用した場合には、収穫前に回収される。この回収作業の効率化を図るために、機械による回収装置が従前より提案されている。   The agricultural multi-sheet laid in the field is collected and discarded after harvesting for cultivation of leafy vegetables and the like. When used for cultivation of root crops, they are collected before harvesting. In order to improve the efficiency of the collection operation, a collection device using a machine has been conventionally proposed.

具体的には、回収作業単独で実施するものや、収穫機に付設したものが知られている。前者では、自走巻き取り専用機で、巻取り駆動源としてエンジンを使用すると共に、作業者が無段階変速機を操作して最適な巻き取りを行うようにしている(特許文献1)。   Specifically, there are known ones that perform the collection work alone and ones that are attached to the harvester. In the former, a self-propelled take-up machine uses an engine as a take-up drive source, and an operator operates a continuously variable transmission to perform optimum take-up (Patent Document 1).

また汎用トラクターに装着して使用する器具として、特許文献2、3記載のアタッチメントが提案されている。特許文献2記載の装置は、トラクターの背後にアタッチメントを装着し、汎用トラクターが備えているアタッチメント駆動機構(PTO軸)によって巻き取り回転駆動を行うようにしている。   Further, attachments described in Patent Literatures 2 and 3 have been proposed as instruments to be used by being mounted on a general-purpose tractor. In the device described in Patent Document 2, an attachment is mounted behind a tractor, and a take-up rotation drive is performed by an attachment drive mechanism (PTO shaft) provided in a general-purpose tractor.

同様に特許文献3記載の装置においても、トラクターの側方に配置するようにし、巻き取り駆動源として正逆回転が可能とした電動機を採用し、特にシート巻き取り回収に際して夾雑物を巻き込まないように、シート振動機構を付設している。   Similarly, in the device described in Patent Document 3, the motor is arranged on the side of the tractor, and a reversing motor is used as a rewind drive source. , A seat vibration mechanism is additionally provided.

更に収穫機にマルチシート回収装置を組み込んで、収穫と同時にマルチシートの回収を行う装置も提案されている(特許文献4)。この装置は、トラクターで牽引される玉葱の収穫装置にマルチシート巻き取り機構を付設し、前記巻き取り機構は、収穫装置の先端の茎葉部切断手段の駆動と連動し、トラクターの動力取り出し軸(PTO軸)を動力源としているものである。マルチシートの巻取りに際して夾雑物がシートに紛れ込まないように、シートを横軸方向で斜めとなるようにして巻き取りを行い、シート上の夾雑物が進行方向の横方に転がり出るようにしている。   Furthermore, a device that incorporates a multi-sheet recovery device into a harvester and collects multi-sheets simultaneously with harvesting has been proposed (Patent Document 4). In this device, a multi-sheet winding mechanism is attached to an onion harvesting device to be pulled by a tractor, and the winding mechanism is interlocked with the drive of a foliage cutting means at the tip of the harvesting device, and a tractor power take-out shaft ( (PTO shaft) as a power source. In order to prevent foreign substances from getting into the sheet when winding the multi-sheet, the sheet is rolled up so that it is inclined in the horizontal axis direction, so that the foreign substances on the sheet roll out to the side in the traveling direction I have.

また収穫と同時にマルチシートを回収せずに、収穫機にマルチシート取り除き装置を付設し、収穫機で畝からマルチシートを引っ張り剥がし、そのまま機体側方に放置するようにしている装置も提案されている(特許文献5)。   Also, there has been proposed a device in which a multi-sheet removing device is attached to the harvester without collecting the multi-sheet at the same time as harvesting, and the multi-sheet is pulled off from the ridge by the harvester and left as it is on the side of the machine. (Patent Document 5).

シートの巻き取り回収に際してシート上に大量の土砂が残っていたり、シート側端が土の中に潜って抑えられている状態では、シートの巻き取り抵抗力が大きくなる場合がある。特許文献1記載のように作業者が細かい操作を行うのであれば、巻取りの停止などの適宜対応できるが、収穫作業と同時にシート回収を行う場合には、収穫作業に忙しくシート回収まで気を回せない。   When a large amount of earth and sand remains on the sheet when the sheet is wound and collected, or when the sheet side end is buried in the soil and held down, the sheet winding resistance may increase. If the operator performs a fine operation as described in Patent Literature 1, it is possible to appropriately take measures such as stopping the winding. However, if the sheet is collected at the same time as the harvesting operation, the user is busy with the harvesting operation and pays attention to the sheet collection. I can't turn it.

しかもシート回収作業の駆動源は原則的に走行機体(トラクター)の原動力を使用するので、細かい制御は困難である。特に巻き取りに際してはシートに突然所定以上の張力が加わっても、何ら巻き取り速度を変更することなく巻き取りを続行すると、張力変化の衝撃力でシートが切断してしまう。そして再度シートの端末を巻き取りボビンに連結して、シート巻き取り回収作業を再開させなければならず、シート切断による作業中断は、収穫作業能率を大きく低下させる原因となる。   In addition, since the driving source of the sheet collecting work basically uses the driving force of the traveling machine (tractor), it is difficult to perform detailed control. In particular, when the winding is continued without changing the winding speed even if the tension is suddenly applied to the sheet or more than a predetermined tension, the sheet is cut by the impact force of the tension change. Then, the terminal of the sheet must be connected to the winding bobbin again to restart the sheet winding and collecting operation. The interruption of the sheet cutting operation causes a great decrease in the efficiency of the harvesting operation.

また付着物や夾雑物の排除においても、振動体を付設するなどの機構は、装置を煩雑にする。   In addition, a mechanism such as the provision of a vibrating body complicates the apparatus even in removing adhering substances and foreign substances.

そこで本発明は、負荷変動に対応して、シート切断の可能性を抑えた、付着部や夾雑物を簡便な機構で排除する機構を備えた根菜収穫機用のマルチシート回収装置を提案したものである。   Therefore, the present invention proposes a multi-sheet collecting apparatus for a root vegetable harvesting machine, which has a mechanism for removing attached parts and foreign substances with a simple mechanism, which suppresses the possibility of sheet cutting in response to load fluctuations. It is.

本発明に係る根菜収穫機用マルチシート回収装置は、収穫機体における前部上方箇所に装着して装置全体を支持すると共に各機構部を所定位置に配設する母体となる支持枠部と、巻き上げマルチシートに添わせるローラを機体進行方向に揺動自在に組み込むと共に、巻取り動作と機体進行が同期せずに、巻取り動作がより早い動作状態に至った際における前記ローラの揺動を感知するセンサを有し、前記センサの検知信号で巻取り駆動を制御するセンサ制御機構部と、負荷が増すと回転数が低下する特性の直流電動機を駆動源とした巻取機構部とを備えてなることを特徴とするものである。   A multi-sheet collecting device for a root cropping machine according to the present invention includes a support frame portion serving as a base for mounting the whole device by mounting the device on a front upper portion of the harvesting machine and arranging each mechanism in a predetermined position, and winding up. A roller attached to the multi-sheet is incorporated so as to be swingable in the body traveling direction, and the winding operation is not synchronized with the body movement, and the swing of the roller is detected when the winding operation reaches an earlier operation state. A sensor control mechanism for controlling the winding drive based on a detection signal of the sensor, and a winding mechanism using a DC motor having a characteristic of decreasing the rotation speed when the load increases as a drive source. It is characterized by becoming.

前記回収装置は、収穫機体の前方に連結装着し、畝からのマルチシート回収と同時に根菜の収穫を行えるもので、特にマルチシートの巻取りに際して、シート上に土砂が残っていたり、シート側端が土によって抑えられている状態の場合には、巻き取り抵抗が大きくなるが、電動機(直巻電動機、和動複巻電動機)本来の特性をもって、負荷トルクが大きくなると回転数が少なくなって、ゆるやかに強い力で巻き取ることになり、シートに衝撃を与えることがなく、シートが切断する等の支障が生じ難く、巻取り作業を継続でき、同時に収穫作業に支障をきたさない。   The collecting device is connected and mounted in front of the harvesting machine, and can collect root vegetables simultaneously with collecting the multi-sheet from the ridge.Especially, when winding up the multi-sheet, soil or sand remains on the sheet, or the sheet side edge In the state where is suppressed by the soil, the winding resistance increases, but with the inherent characteristics of the electric motor (series-wound electric motor, sum-acting double-wound electric motor), the rotational speed decreases as the load torque increases, Since the sheet is wound up with a gentle and strong force, no impact is given to the sheet, troubles such as cutting of the sheet hardly occur, the winding operation can be continued, and at the same time, the harvesting operation is not hindered.

更にセンサ制御機構部の揺動ローラがシート巻取り状態を検知し、収穫機体の進行とシート巻取り動作が同期しない状態に至ると、シートによって揺動ローラを架設した揺動腕が所定の軸を中心に回動し、これをセンサで感知し、駆動源(電動機)を停止したり減速するなどの制御を行うことで、シートの断裂が防止できる。   Further, the swing roller of the sensor control mechanism detects the sheet winding state, and when the progress of the harvesting machine and the sheet winding operation are not synchronized, the swing arm having the swing roller provided by the sheet is rotated by a predetermined axis. , The sensor is detected by this sensor, and control such as stopping or decelerating the drive source (electric motor) can prevent the sheet from being torn.

また本発明(請求項2)は、特に支持枠部に、巻取り途中にシート表裏面に各々当接する受けローラとスポンジ体を有する夾雑物除去機構部を設けてなることを特徴とするものである。   The present invention (Claim 2) is characterized in that the supporting frame portion is provided with a receiving roller which comes into contact with the front and back surfaces of the sheet during winding, and a foreign matter removing mechanism portion having a sponge body. is there.

従ってシート巻取りに際して、シートが受けローラとスポンジ体の間を通過することで、付着した土砂や、農作物の茎部分などの夾雑物を除去できる。   Therefore, at the time of winding the sheet, the sheet passes between the receiving roller and the sponge body, so that it is possible to remove the attached dirt and contaminants such as the stem portion of the crop.

更に本発明(請求項3)は、前記支持枠部に、マルチシート巻上げ方向が約鉛直方向となるように各機構部を配設してなることを特徴とするものである。   Further, the present invention (claim 3) is characterized in that each mechanism is disposed on the support frame so that the multi-sheet winding direction is substantially vertical.

従ってマルチシートが鉛直に近い状態で巻き上げられると、付着しているシートと畝表面とを離れ易くし、更に土砂の付着も少なくてすむ。   Therefore, when the multi-sheet is wound up in a nearly vertical state, it is easy to separate the adhering sheet from the ridge surface, and the adhesion of earth and sand can be reduced.

本発明は、根菜収穫機に装着するもので、特に駆動機構として、負荷が増すと回転数が低下する特性を備えた直流電動機を採用して、特別な制御回路を必要としないで、シート巻取り時にシートに強い衝撃を与えることが無いようにしてシートの断裂を防止し、更に前記駆動機構を採用したことによって生ずると予想される所定状態(軽負荷で巻取り速度が早まり、巻取り動作が収穫機の進行速度より早くなりすぎる場合に生ずる状態)に駆動源を制御することで巻取り回収時のシート切断を防止し、同時に進行する収穫作業の支障とならないようにしてシート回収を行う。   The present invention is mounted on a root cropper, and in particular, adopts a DC motor having a characteristic that the number of rotations decreases as the load increases as a driving mechanism, and does not require a special control circuit, and the sheet winding is performed. The sheet is prevented from being torn at the time of taking-up so that a strong impact is not applied to the sheet, and a predetermined state expected to be caused by adopting the drive mechanism (the winding speed is increased with a light load, and the winding operation is performed) Is controlled when the drive source is controlled to prevent the sheet from being cut off at the time of winding and collecting, and the sheet is collected so as not to hinder the harvesting operation to be performed at the same time. .

次に本発明の実施の形態について説明する。本発明の回収装置Aは、自走根菜収穫機Bの前部に連結装着して使用されるものである。   Next, an embodiment of the present invention will be described. The collecting device A of the present invention is used by being connected to and attached to the front of a self-propelled root vegetable harvesting machine B.

自走根菜収穫機Bは、周知の通り主として芋類収穫機と使用されるもので、クローラを装備した機体に、先端側が下降するように傾斜した掘取りコンベア機構を設けたものである。このコンベア機構は、側枠間に所定間隔のスラットを設けた掘取りコンベアを巻装し、側枠の途中から掘取りコンベアと共に機体側に折り畳めるようになっている。更に側枠の先部には、一対のホイールからなる畝追尾機構を設けており、掘り取りコンベアに連続して選別コンベアが設けられ、機体に乗車した作業者が選別コンベアで搬送される収穫物の選別を行うようにしている。   The self-propelled root vegetable harvesting machine B is mainly used as a potato harvesting machine as is well known, and is provided with a digging conveyor mechanism that is inclined so that the tip side is lowered on a body equipped with a crawler. In this conveyor mechanism, a digging conveyer provided with slats at predetermined intervals between side frames is wound, and can be folded toward the machine body together with the digging conveyer from the middle of the side frame. In addition, a ridge tracking mechanism consisting of a pair of wheels is provided at the end of the side frame, and a sorting conveyor is provided continuously with the digging conveyor, and workers who got on the machine are transported by the sorting conveyor. Is to be sorted out.

回収装置Aは、前記の収穫機体Bにアタッチメントとして装着されるもので、支持枠部1と、支持枠部1に組み込まれる巻取り機構部2と、センサ制御機構部3と、夾雑物除去機構部4と、ガイド部5とで構成される。   The collecting device A is attached to the harvesting machine body B as an attachment, and includes a support frame 1, a winding mechanism 2 incorporated in the support frame 1, a sensor control mechanism 3, and a contaminant removal mechanism. It is composed of a section 4 and a guide section 5.

支持枠部1は、適宜な台枠11と台枠11を支持する支持脚12を備え、支持脚12を直接又は取付部材13を介して自走根菜収穫機Bの側枠aや畝追尾機構bに固定することで、回収装置全体を自走機体Bに装着することになる。   The support frame 1 includes an appropriate underframe 11 and a support leg 12 that supports the underframe 11, and the support leg 12 is directly or via the attachment member 13 to the side frame a of the self-propelled root vegetable harvester B or the ridge tracking mechanism. b, the entire collection device is mounted on the self-propelled vehicle B.

図5は取付部材13の具体例で、畝追尾機構b等への装着部131と、連結杆132と支持脚取付部133で構成され、装着部131はボルト装着可能なボルト孔を穿設した取付板134と、補助連結杆132を挿通する筒部135とを一体とし、筒部135に固定ボルト136を植立螺装してなり、畝追尾機構b等にこの装着部131を固定する。更に支持脚取付部133を、支持脚12を連結するU状装着部137と筒部138で構成し、筒部138に連結杆132を挿通固定し、U状装着部137に支持脚12を連結する等して、支持枠部1を機体Bに取り付ける。   FIG. 5 shows a specific example of the mounting member 13, which includes a mounting portion 131 for the ridge tracking mechanism b and the like, a connecting rod 132 and a support leg mounting portion 133, and the mounting portion 131 has a bolt hole through which a bolt can be mounted. The mounting plate 134 is integrated with a cylindrical portion 135 through which the auxiliary connecting rod 132 is inserted, and a fixing bolt 136 is screwed into the cylindrical portion 135, and the mounting portion 131 is fixed to the ridge tracking mechanism b or the like. Further, the support leg attachment portion 133 is constituted by a U-shaped mounting portion 137 for connecting the support leg 12 and a cylindrical portion 138, a connecting rod 132 is inserted through and fixed to the cylindrical portion 138, and the support leg 12 is connected to the U-shaped mounting portion 137. Then, the support frame 1 is attached to the fuselage B.

巻取機構部2は、駆動源となる電動機21及び巻取部22と伝達機構23で構成され、これらは支持枠部1の所定位置に組み込まれたもので、駆動源となる電動機21は、機体装備のバッテリー電源を使用する所定出力の直流電動機で、特に負荷が増すと回転数が低下する所定の特性を備えてなる。   The winding mechanism unit 2 includes a motor 21 serving as a driving source, a winding unit 22 and a transmission mechanism 23, which are incorporated in a predetermined position of the support frame unit 1, and the motor 21 serving as a driving source is A DC motor having a predetermined output using a battery power source of an airframe, and having a predetermined characteristic that the number of rotations decreases particularly when the load increases.

巻取部22は、中心軸221と、中心軸221の外周に中心軸と平行に配置した巻取棒222を備えると共に、巻取棒222を中心軸221の基部及び先部に設けたリンク連結部223,224とで連結し、特に先部リンク連結部223は、中心軸221に移動可能としたスライド環225を介して連結し、巻取外径と前記巻取外径より全体を小径とした離脱外径とに移行できるようにしてなるものである。   The winding unit 22 includes a central shaft 221 and a winding rod 222 arranged on the outer periphery of the central shaft 221 in parallel with the central axis, and a link connection provided with the winding rod 222 at the base and the tip of the central shaft 221. Parts 223, 224, and in particular, the front link connecting part 223 is connected via a slide ring 225 movable to the center shaft 221 so that the winding outer diameter is smaller than the winding outer diameter as a whole. It is possible to shift to the separated outside diameter.

前記の巻取部22はその中心軸221を支持枠部の固定軸受部と、開閉杆14の軸受部間に架設し、伝達機構23を介して電動機21で回転駆動されるものである。   The winding portion 22 has a center shaft 221 provided between a fixed bearing portion of the support frame portion and a bearing portion of the opening / closing rod 14, and is driven to rotate by the electric motor 21 via the transmission mechanism 23.

センサ制御機構部3は、巻取り対象のマルチシートCに当接する揺動ローラ31と、揺動ローラ31を架設した揺動腕32と、揺動腕32の揺動角度で動作するマイクロスイッチ(センサ)33で構成される。   The sensor control mechanism 3 includes a swing roller 31 that contacts the multi-sheet C to be wound, a swing arm 32 having the swing roller 31, and a micro switch (operating at a swing angle of the swing arm 32). Sensor) 33.

揺動腕32は、支持枠部1の所定位置から機体Bの進行方向に揺動するように枢止し、シートの巻取り角度が浅くなる(鉛直方向から傾斜方向に移行)と、前記センサ33を動作せしめるように設け、且つ前記センサ方向への揺動と反対方向へ適宜な力で付勢するための発条34を設けてなる。   The swing arm 32 pivots from a predetermined position of the support frame portion 1 so as to swing in the traveling direction of the body B, and when the sheet winding angle becomes shallow (transition from the vertical direction to the inclined direction), the sensor 33 is provided so as to operate, and a spring 34 is provided for urging with an appropriate force in a direction opposite to the swing in the sensor direction.

夾雑物除去機構部4は、前記揺動ローラ31と巻取部22との間に介設したもので、シートCの巻回ガイドとなるローラ41と、前記ローラ41に対面するスポンジ体42で構成される。尚スポンジ体42とローラ41のシートCに対する当接面を逆にして、二重構成とすると、シートCの表裏両面の付着物が取り除かれる。   The contaminant removal mechanism unit 4 is interposed between the swing roller 31 and the winding unit 22, and includes a roller 41 serving as a winding guide for the sheet C and a sponge body 42 facing the roller 41. Be composed. If the sponge body 42 and the roller 41 are in a two-sided configuration with the abutting surfaces of the rollers 41 in contact with the sheet C, deposits on both the front and back surfaces of the sheet C are removed.

ガイド部5は、シートCの巻取りに際して、シートCが収穫機体Bの収穫機構の邪魔にならないようにし、且つ揺動ローラ31へのシート当接が清浄に行われるようにしたものである。   The guide section 5 prevents the sheet C from interfering with the harvesting mechanism of the harvesting machine B when the sheet C is wound, and cleanly contacts the swing roller 31 with the sheet.

而して前記回収装置Aを自走収穫機体Bの所定位置(側枠aや畝追尾機構b)に連結装着し、畝の端に位置させた機体Bの回収装置Aに、シートCの端部を所定の巻回コースで巻取部22に引っ掛けておき、機体Bを自走させながら回収装置を動作させると、機体Bの掘取りコンベアの先端でシートCが捲り上げられ、そのまま巻取部22に巻き取られることになり、収穫作業とシート巻取り作業が同時になされることになる。   The collecting device A is connected to a predetermined position (side frame a and ridge tracking mechanism b) of the self-propelled harvesting machine B, and is attached to the collecting device A of the machine B positioned at the end of the ridge. The unit C is hooked on the winding unit 22 in a predetermined winding course, and when the collecting device is operated while the body B is self-propelled, the sheet C is wound up at the tip of the digging conveyor of the body B, and the winding is performed as it is. Thus, the harvesting operation and the sheet winding operation are performed at the same time.

特にシートCの上に土砂の付着量が多くなるなどの原因で、巻き取り抵抗が大きくなって電動機負荷が増加すると、電動機の回転数が減少して、ゆるやかな強い力で巻き取ることになり、更に自走機体Bの走行に比較してシートの巻き取りが進行して、シートCに張りが生ずると、シートCが揺動ローラを押し出して、発条34の付勢力に抗して揺動腕32を回動させると、センサ33が動作して駆動源(電動機)21を停止し、シート巻取り動作を一時停止する。そしてシートCにゆとりが生じて揺動腕32が元の状態に復帰すると、停止状態を解消して巻き取り動作を再開する。   In particular, when the winding resistance increases and the motor load increases due to an increase in the amount of sediment deposited on the sheet C, the number of revolutions of the motor decreases, and the winding is performed with a gentle and strong force. Further, when the winding of the sheet progresses as compared with the traveling of the self-propelled body B and the sheet C becomes taut, the sheet C pushes out the swing roller, and swings against the urging force of the spring 34. When the arm 32 is rotated, the sensor 33 operates to stop the drive source (electric motor) 21 and temporarily stop the sheet winding operation. When the swing arm 32 returns to the original state due to the clearance in the sheet C, the stopped state is canceled and the winding operation is restarted.

従って収穫作業に従事する者は、巻き取り回収状態を常に注意深く観察しながら走行する必要がなく、自動的に巻き取り動作が制御されるので、巻き取り回収作業が容易になると共に、シート切断を抑えることができるので、作業能率も格段に向上する。   Therefore, it is not necessary for the worker engaged in the harvesting operation to travel while always carefully observing the winding and collecting state, and the winding operation is automatically controlled. Since it can be suppressed, work efficiency is also greatly improved.

そして巻き取り回収が終了すると、開閉杆14を開放し、中心軸221の先端部分を露出させると共に、スライド環225を移動させ、巻取棒222を中心軸221方向に集束させて、巻取棒222に巻回されたシートCを装置外に取り出すものである。   When the winding and collection is completed, the opening / closing rod 14 is opened to expose the tip of the central shaft 221, and at the same time, the slide ring 225 is moved to converge the winding rod 222 in the direction of the central axis 221. The sheet C wound around 222 is taken out of the apparatus.

特に前記実施形態は、機体進行方向に対して後退回転で巻き取る様にしたので、シートCの捲り上げを約鉛直方向にすることができ、これによって畝とシートCの付着に対して容易に捲り取ることが可能となり、更にシート表面の栽培植物の茎部分が落下し易いし、シート裏面の付着土壌が少なくなる。   In particular, in the above-described embodiment, the sheet C is wound in the backward rotation with respect to the advancing direction of the fuselage, so that the sheet C can be wound up in a substantially vertical direction. It can be rolled up, and the stem portion of the cultivated plant on the surface of the sheet can easily fall off, and the amount of soil attached to the back surface of the sheet can be reduced.

また前記実施形態のように巻取部を後退回転とせずに前進回転とした場合に、シートCの剥ぎ取りを鉛直方向に設定すると回収装置A自体が機体Bの前方となりバランスが悪くなる。このような場合には、図6に例示するとおり、センサ制御機構部3にシートCがきちんと導かれるように、鳥居型のガイド部5aを設けると、前進回転タイプの回収装置も実現でき、市場の多機種の自走収穫機に対応できるものである。   In the case where the winding unit is rotated forward instead of backward as in the above-described embodiment, if the stripping of the sheet C is set in the vertical direction, the collection device A itself becomes forward of the body B, and the balance is deteriorated. In such a case, as shown in FIG. 6, if a torii-shaped guide portion 5a is provided so that the sheet C is properly guided to the sensor control mechanism portion 3, a forward rotation type recovery device can be realized. It is compatible with many types of self-propelled harvesters.
