Description

本発明は、人参等の根菜類を収穫する収穫機に関するものである。   The present invention relates to a harvester that harvests root vegetables such as carrots.

先行特許文献１に記載の根菜類収穫機は、引抜搬送装置で圃場から作物を引き抜き後方に搬送し、この作物をタッピング装置で肩揃えして茎葉部を切断し、落下してきた作物に残る残葉部を残葉処理部で処理しながら搬送し、選別搬送装置の搬送終端部に設けたフレコンバッグで作物を回収する構成のものである。   The root vegetable harvesting machine described in the prior patent document 1 pulls out a crop from a field by a pulling and conveying device, conveys the crop to the rear, cuts the foliage by shoulder-aligning the crop with a tapping device, and remains in the falling crop. The leaf portion is conveyed while being processed by the remaining leaf processing portion, and the crop is collected with a flexible container bag provided at the conveyance terminal portion of the sorting and conveying device.

特開２０１２−１１５１５７号公報JP 2012-115157 A

引抜搬送装置は、圃場に植生する作物の茎葉部を挟持して引き抜くものであり、茎葉部が短い場合は始端部を圃場面に接近させる必要がある。この際引抜搬送装置が茎葉部を挟持すると同時に作物の周囲の土砂を一緒に挟持することが多く、この土砂が作物と共に後工程に搬送されてしまい、機体の各部に付着した土砂を除去する作業が必要となり、作業者の費やす時間と労力が増大する問題がある。   The pulling and conveying device is for pulling out the foliage of a crop to be vegetated in the field, and when the foliage is short, it is necessary to bring the starting end close to the field scene. At this time, the pulling / conveying device often holds the soil around the crop at the same time as the foliage is sandwiched, and the soil is transported to the subsequent process together with the crop, and the work removes the sediment attached to each part of the machine body. Is required, and there is a problem that the time and labor that the operator spends increases.

この搬送された土砂を放置した場合は、各搬送装置の伝動部、例えばスプロケットとチェーンの隙間に入り込むと、土砂の噛み込みによるチェーンの脱落や、過負荷による伝動系の構成部材の破損が生じるという問題がある。これにより作物の収穫作業が長時間に亘って中断される問題や、修理に時間と労力を余分に労する問題が生じる。   If the transported earth and sand are left unattended, if they enter the gap between the sprockets and the chain of each transport device, for example, the chain will fall off due to the biting of the sand and the components of the transmission system will be damaged due to overload. There is a problem. As a result, there arises a problem that the crop harvesting operation is interrupted for a long time and a problem that extra time and labor are required for repair.

なお、この過負荷による伝動系の構成部材の破損に対してはシャーピン等の安全装置を設けることにより、主要な部材の破損を防止することは可能であるが、安全装置の交換作業は必要であり、その分収穫作業が中断されるので、作業能率が低下する。   Although it is possible to prevent damage to major members by providing a safety device such as a shear pin against damage to the components of the transmission system due to this overload, replacement of the safety device is necessary. Yes, since the harvesting work is interrupted accordingly, the work efficiency is lowered.

各搬送装置の伝動部をベルトで構成すると構成部材の破損の問題は生じにくいが、ベルト搬送では土砂が作物と共に搬送されるため、土砂が作物の傷等を隠し、収穫に適さない作物まで収穫されてしまい、選別精度が下がる問題や、フレコンバッグに土砂が入り込み、作物の収容量がその分減少し、フレコンバッグを下ろす作業や装着する作業の回数が増え、作業能率が低下する問題が生じる。   Constructing the transmission part of each conveyor device with a belt makes it difficult for components to break. However, with the belt conveyor, soil and sand are transported together with the crop, so the soil and sand hide crop damage and harvest crops that are not suitable for harvesting. This causes problems such as reduced sorting accuracy, soil and sand entering the flexible container bag, and a reduction in the amount of crops stored, increasing the number of operations for lowering and attaching the flexible container bag, and lowering work efficiency. .

よって作物に付着した土砂を適切に除去する装置を引抜搬送装置に備えた根菜類収穫機を提供することが、本発明が解決しようとする課題である。   Therefore, it is a problem to be solved by the present invention to provide a root crop harvester equipped with an apparatus for properly removing earth and sand adhering to crops.

With a cutting blade 27 provided at the front, a rotatable gauge wheel 31 that prevents the pulling / conveying device 24 from going down too much at the lower end of the telescopic rod 30 that expands and contracts when the handle 29 is turned, and the driving force of the engine Left and right vibration solitaries 34 and 34 are provided for solving the left and right soils of carrots attached to a vibration frame 33 that vibrates by rotation of the rotating shaft 32 by vibration. A harvesting unit C is configured by attaching a tail cutting device 35 for cutting the carrot root of the carrot being conveyed by the drawing and conveying device 24 below the drawing and conveying passage.

本発明の第一実施形態にかかる根菜類収穫機は、図５及び図６に示すように、引抜搬送装置２４の前部下側に作物の周囲の土砂を除去する土砂除去装置１５０を備える。図５はこの土砂除去装置１５０を備える引抜搬送装置２４の前部周辺の右側面図であり、図６は図５で記載したＰ方向から見た引抜搬送装置２４の前部周辺の平面図である。この土砂除去装置１５０は、円板状の土砂除去ディスク１５４からなる土砂除去部材と、この土砂除去部材を回転自在に備える、ギアボックスである回転伝動手段１５１とから構成する。回転伝動手段１５１は、引抜搬送装置２４の前部下側にボルトにより固定され、内部には、引抜搬送装置２４の従動プーリ１６の回転軸と一体化し、引抜搬送装置２４からの回転動力を受ける入力歯車である入力伝動体１５２と、土砂除去ディスク１５４の回転軸と一体化し、土砂除去ディスク１５４に回転動力を付与する出力伝動体１５３と、から構成する。   As shown in FIGS. 5 and 6, the root vegetable harvester according to the first embodiment of the present invention includes a soil removal device 150 that removes soil around the crop on the lower side of the front portion of the pulling and conveying device 24. FIG. 5 is a right side view of the periphery of the front portion of the drawing / conveying device 24 provided with the earth and sand removing device 150. FIG. 6 is a plan view of the periphery of the front portion of the drawing / conveying device 24 as viewed from the P direction shown in FIG. is there. The earth and sand removing device 150 includes an earth and sand removing member composed of a disk-like earth and sand removing disk 154, and a rotary transmission means 151 that is a gear box and rotatably includes the earth and sand removing member. The rotation transmission means 151 is fixed to the lower side of the front portion of the drawing / conveying device 24 by a bolt, and is internally integrated with the rotating shaft of the driven pulley 16 of the drawing / conveying device 24 and receives rotational power from the drawing / conveying device 24. An input transmission body 152 that is a gear and an output transmission body 153 that is integrated with the rotary shaft of the sediment removal disk 154 and applies rotational power to the sediment removal disk 154 are configured.

出力伝動体１５３と入力伝動体１５２とは、作物の搬送軌跡に沿って並ぶようにし、前側には出力伝動体１５３を配置する。出力伝動体１５３と入力伝動体１５２は歯車であるので、それらが噛合うことで、出力伝動体１５３が、入力伝動体１５２と逆方向に回転するようになる。出力伝動体１５３と入力伝動体１５２との潤滑はグリスにより行う。   The output transmission body 153 and the input transmission body 152 are arranged along the crop conveyance locus, and the output transmission body 153 is arranged on the front side. Since the output transmission body 153 and the input transmission body 152 are gears, the output transmission body 153 rotates in the opposite direction to the input transmission body 152 when they mesh with each other. Lubrication of the output transmission body 153 and the input transmission body 152 is performed with grease.

土砂除去装置１５０の土砂除去ディスク１５４が、作物に付着した土砂に接する点が、土砂除去装置１５０の作用点Ｔとなる。この作用点Ｔは、理論上土砂除去ディスク１５４の外周円であって、Ｐ方向から見た時に土砂除去ディスク１５４の中心点を通る、作物の搬送軌跡への垂線と交差する点である。また引抜搬送装置２４の搬送開始点Ｓは、引抜搬送装置２４の左右の挟持搬送ベルト１８が最も近づいた点を言う。第一実施形態にかかる根菜類収穫機は、土砂除去装置１５０の作用点Ｔが、引抜搬送装置２４の搬送開始点Ｓよりも前側に位置するように構成する。ここで「前側」とは図６のＰ矢視での前側を言う。   The point at which the sediment removal disk 154 of the sediment removal device 150 contacts the soil attached to the crop is the operating point T of the sediment removal device 150. The point of action T is theoretically the outer circumferential circle of the sediment removal disk 154 and is a point that intersects the perpendicular to the crop conveyance trajectory passing through the center point of the sediment removal disk 154 when viewed from the P direction. The conveyance start point S of the drawing / conveying device 24 is a point where the left and right nipping / conveying belts 18 of the drawing / conveying device 24 are closest to each other. The root vegetable harvester according to the first embodiment is configured such that the action point T of the earth and sand removing device 150 is positioned in front of the conveyance start point S of the drawing conveyance device 24. Here, “front side” refers to the front side as viewed in the direction of arrow P in FIG.

土砂除去装置１５０、１５０は、引抜搬送装置２４の下方に左右一対となるように設け、左右の土砂除去ディスク１５４、１５４の間、即ち土砂除去ディスク１５４、１５４の外周の最も近接した距離が、引抜搬送装置２４により引き抜かれた作物が通過可能な間隔部Ｕを構成するようにする。土砂除去ディスク１５４の径が、出力伝動体１５３の径以上であるので、土砂除去ディスク１５４の回転数が、引抜搬送装置２４を構成する従動プーリ１６の回転数以上であると、土砂除去ディスク１５４の外周速度が、引抜搬送装置２４を構成する挟持搬送ベルト１８の速度以上となる。   The earth and sand removing devices 150 and 150 are provided in a pair of left and right below the pulling and conveying device 24, and the closest distance between the left and right earth and sand removing disks 154 and 154, that is, the outer periphery of the earth and sand removing disks 154 and 154, An interval portion U through which the crop extracted by the extraction conveying device 24 can pass is configured. Since the diameter of the earth and sand removal disk 154 is equal to or larger than the diameter of the output transmission body 153, the earth and sand removal disk 154 is set when the rotation speed of the earth and sand removal disk 154 is equal to or larger than the rotation speed of the driven pulley 16 constituting the pulling and conveying device 24. Is equal to or higher than the speed of the nipping / conveying belt 18 constituting the drawing / conveying device 24.

土砂除去ディスク１５４は、一例として、硬質ゴム製で構成するものであり、外周縁部には凹凸を形成する。なお、硬質ゴム以外には、低負荷時は変形せず、高負荷時は変形する程度の硬さの合成樹脂を用いて構成してもよい。   The earth and sand removal disc 154 is made of hard rubber, for example, and has irregularities on the outer peripheral edge. In addition to the hard rubber, it may be configured using a synthetic resin having a hardness that does not deform at a low load and deforms at a high load.

引抜搬送装置２４の前部に備えた土砂除去装置１５０の作用点Ｔが、引抜搬送装置２４の搬送開始点Ｓよりも前側に位置することにより、作物を圃場から引き抜く際に土砂が一緒に搬送されることを防止できるので、各作業装置の、土砂を噛み込むことによる破損が防止される。   When the action point T of the sediment removal device 150 provided in the front part of the drawing and conveying device 24 is positioned in front of the conveyance starting point S of the drawing and conveying device 24, the earth and sand are conveyed together when the crop is extracted from the field. As a result, it is possible to prevent breakage of each working device caused by biting earth and sand.

また、圃場にある作物の周辺の土砂を除去できるようになり、引抜搬送装置２４の搬送始端部Ｓを従来よりも圃場面に近づけることができるので、茎葉部の短い作物の引抜収穫を行うことができ、作業条件の適応性が向上する。   In addition, the soil around the crop in the field can be removed, and the transport start end S of the pulling and transporting device 24 can be brought closer to the field scene than before, so that the crop with a short foliage is pulled out. And the adaptability of working conditions is improved.

加えて機体の各部に付着した土砂を除去する作業が不要となり、作業時間と労力を軽減することができる。   In addition, it is not necessary to remove the earth and sand adhering to each part of the machine body, and the work time and labor can be reduced.

出力伝動体１５３が、入力伝動体１５２と逆方向に回転する構成としたことにより、土砂除去部材の作用方向を引抜搬送装置２４の搬送方向と逆方向にすることができるので、土砂には引抜搬送装置２４の搬送開始点Ｓから遠ざかる方向に力が作用し、土砂が引抜搬送装置２４により搬送されることを防止できる。   Since the output transmission body 153 rotates in the direction opposite to that of the input transmission body 152, the direction of action of the earth and sand removing member can be made opposite to the conveyance direction of the extraction conveyance device 24. A force acts in a direction away from the transfer start point S of the transfer device 24, and the earth and sand can be prevented from being transferred by the drawing transfer device 24.

また、土砂除去装置１５０を引抜搬送装置２４の下側に設けると共に、土砂除去装置１５０の回転伝動手段１５１を構成する出力伝動体１５３が入力伝動体１５２よりも前側に位置することにより、引抜搬送装置２４が作物の茎葉部を挟持するより前に、土砂除去装置１５０が作物の土砂を除去することができる。   Further, the earth and sand removing device 150 is provided on the lower side of the drawing and conveying device 24, and the output transmission body 153 constituting the rotational transmission means 151 of the earth and sand removing device 150 is positioned on the front side of the input transmission body 152, thereby drawing and conveying. The soil removal device 150 can remove the soil from the crop before the device 24 sandwiches the foliage of the crop.

左右一対の土砂除去装置１５０、１５０を、これらの土砂除去装置１５０、１５０を構成する土砂除去部材間を引き抜かれた作物が通過可能な間隔部Ｕを設けて配置したことにより、土砂除去装置１５０、１５０が作物に接触して傷つけることを防止でき、作物の商品価値を維持することができる。   By arranging the pair of left and right earth removing devices 150, 150 with an interval portion U through which a crop drawn between the earth removing members constituting the earth removing devices 150, 150 can pass, the earth removing device 150 is provided. , 150 can be prevented from being damaged by contact with the crop, and the commercial value of the crop can be maintained.

また、土砂除去部材の回転数が、引抜搬送装置２４を構成する従動プーリ１６の回転数以上であることにより、土砂除去部材の外周速度が、引抜搬送装置２４を構成する挟持搬送ベルト１８の速度以上となり、作物の周囲の土砂を除去し終えてから引抜搬送装置２４で挟持して引き抜くことができるので、作物を圃場から引き抜く際に土砂が一緒に搬送されることが防止される。これにより土砂の噛み込みによる各作業装置の破損が防止され、作業能率が向上する。   Further, since the rotation speed of the earth and sand removing member is equal to or higher than the rotation speed of the driven pulley 16 that constitutes the drawing and conveying apparatus 24, the outer peripheral speed of the earth and sand removing member is the speed of the nipping and conveying belt 18 that constitutes the drawing and conveying apparatus 24. As described above, after removing the soil around the crop, it can be held and pulled out by the pulling / conveying device 24, so that the soil is prevented from being transported together when the crop is pulled out from the field. Thereby, the breakage of each working device due to the biting of earth and sand is prevented, and the working efficiency is improved.

作物の周辺の土砂を除去することにより、引抜搬送装置２４の搬送開始点Ｓを従来よりも圃場面に近づけることができるので、土砂の持ち上げを気にすることなく茎葉部の短い作物の引抜収穫を行うことができ、作業条件の適応性が向上する。   By removing the soil around the crop, the transport start point S of the pulling and transporting device 24 can be brought closer to the field than before, so that the crop with a short foliage can be harvested without worrying about lifting the soil. And the adaptability of the working conditions is improved.

土砂除去部材が、円板状の土砂除去ディスク１５４であることにより、機体の前後及び上下方向の取付スペースを小さくすることができ、土砂除去装置１５０をコンパクトに構成することができる。   Since the earth and sand removing member is a disk-like earth and sand removing disk 154, the mounting space in the front and rear and up and down directions of the machine body can be reduced, and the earth and sand removing apparatus 150 can be configured in a compact manner.

また、土砂除去ディスク１５４の外周縁部に凹凸を形成したことにより、この凹凸で土砂を土砂除去ディスク１５４の回転方向に案内することができ、作物の周囲の土砂が引抜搬送装置２４により搬送されるのを防止できる。これにより土砂の噛み込みによる各作業装置の破損が防止され、作業能率が向上する。   Further, by forming irregularities on the outer peripheral edge of the earth and sand removal disc 154, the earth and sand can be guided in the rotation direction of the earth and sand removal disk 154 by the irregularities, and the earth and sand around the crop is conveyed by the drawing and conveying device 24. Can be prevented. Thereby, the breakage of each working device due to the biting of earth and sand is prevented, and the working efficiency is improved.

A hole that is long in the front-rear direction is formed on the upper side of the rotating plate 119.

そして、該回動プレート１１９に形成した孔部と、操作支持プレート１１８の上部との間に、一方の棒材の表面に螺子溝を刻み、他方の中空の棒材の内面に螺子溝を刻み、互いの棒体の螺子溝を合わせて構成する螺子ロッド１２０を設け、該螺子ロッド１２０の後側端部に螺子ロッド１２０を回転させて伸縮させる操作モータ１２１を取り付けるにより、載置排出部Ｈが構成される。   Then, between the hole formed in the rotating plate 119 and the upper part of the operation support plate 118, a screw groove is cut on the surface of one bar, and a screw groove is cut on the inner surface of the other hollow bar. The mounting discharge unit H is provided by providing a screw rod 120 configured by combining the screw grooves of the rods of each other, and attaching an operation motor 121 that rotates and extends the screw rod 120 to the rear end portion of the screw rod 120. Is configured.

なお、該操作モータ１２１を操作するスイッチやレバー等の操作部材は、前記操縦パネル１２に設けると操縦者が補助作業者の指示に従って操作し易くなると共に、操作支持プレート１１８に設けると補助作業者が収容容器９７を降ろしながら操作しやすくなり、作業能率が向上する。また、螺子ロッド１２０は、電動シリンダや油圧シリンダ等の伸縮部材に置き換えてもよい。   When operating members such as switches and levers for operating the operating motor 121 are provided on the control panel 12, it is easy for the operator to operate according to the instructions of the auxiliary operator, and when provided on the operation support plate 118, the auxiliary operator is provided. However, it becomes easy to operate while lowering the storage container 97, and work efficiency is improved. Further, the screw rod 120 may be replaced with a telescopic member such as an electric cylinder or a hydraulic cylinder.

前記載置バケット１１７は、この載置バケット１１７の回動支点となる排出回動軸を機体左右他側ほど上方に位置する上方傾斜姿勢に配置し、載置バケット１１７を最大限上方回動させると圃場面を基準として略平行姿勢となる構成とすると共に、載置バケット１１７を下方に回動させると、載置バケット１１７の前側端部は下降するほど機体フレーム１から機体左右他側に離間していく構成とする。   The placement bucket 117 is arranged in an upwardly inclined posture in which the discharge turning shaft serving as a turning fulcrum of the placement bucket 117 is located upward on the left and right sides of the machine body, and the placement bucket 117 is rotated upward as much as possible. When the mounting bucket 117 is rotated downward, the front end of the mounting bucket 117 moves away from the body frame 1 to the left and right sides of the body. It is set as the structure to do.

なお、収容容器９７を機体前側に向かって圃場に降ろし、引抜収穫作業に復帰する際は、まず機体を後進させて収容容器９７を載置バケット１１７から確実に離れさせ、次に機体を前進させ、機体左右他側の端部に位置する載置バケット１１７が接触しない位置に退避して前進し、収容容器９７に接触するおそれが無くなると、人参の収穫条に戻る操作を行なう。   When the storage container 97 is lowered to the field toward the front side of the machine body and returned to the pulling and harvesting operation, the machine body is first moved backward to securely separate the storage container 97 from the mounting bucket 117, and then the machine body is advanced. When the placement bucket 117 located at the end of the left and right sides of the machine body is retracted to a position where it does not contact and moves forward, and there is no possibility of contacting the storage container 97, an operation to return to the carrot harvesting line is performed.

本発明の別の実施形態について説明する。
本発明の第二実施形態にかかる根菜類収穫機は、図７に示す土砂除去装置１５０を設ける。図７はこの土砂除去装置１５０を備える引抜搬送装置２４の前部周辺の右側面図である。第一実施形態の土砂除去装置１５０との相違点は、土砂除去部材が、円板の下部に、複数の紐体の一端部を固定した排土部材１５５であることである。この排土部材１５５は、排土部材１５５を回転すると、遠心力により紐体の他端部が外側に向けて広がるようになる。 Another embodiment of the present invention will be described.
The root crop harvesting machine according to the second embodiment of the present invention is provided with a soil removal device 150 shown in FIG. FIG. 7 is a right side view of the periphery of the front portion of the drawing and conveying apparatus 24 including the earth and sand removing device 150. The difference from the earth and sand removing device 150 of the first embodiment is that the earth and sand removing member is an earth discharging member 155 in which one end portions of a plurality of string bodies are fixed to the lower part of the disk. When the earth removing member 155 rotates, the earth removing member 155 causes the other end portion of the string body to spread outward due to centrifugal force.

なお、この排土部材１５５を、土砂除去ディスク１５４の下方に設けることも可能である。この場合、二重に土砂を除去することができる。   Note that the soil removal member 155 can be provided below the sediment removal disk 154. In this case, the earth and sand can be removed twice.

土砂除去部材が、円板の下部に、複数の紐体の一端部を固定した排土部材１５５であり、土砂除去部材を回転させることで遠心力により紐体の他端部が外側に広がることにより、排土部材１５５により作物が傷つくことを防止できるので、作物の商品価値を維持できる。
なお、前記排土部材１５５は、塩化ビニルやゴムなどの撓みやすい材質で構成するものとすると、圃場面と接触の際に多少傷ついても土砂の除去効果が低下しにくくなるので、排土部材１５５が使用不能になるまでの期間が長くなる。 The earth and sand removing member is a soil discharging member 155 in which one end portions of a plurality of string bodies are fixed to the lower part of the disk, and the other end portion of the string body is spread outward by centrifugal force by rotating the earth and sand removing member. Thus, it is possible to prevent the crop from being damaged by the soil removal member 155, so that the commercial value of the crop can be maintained.
If the earth removing member 155 is made of a flexible material such as vinyl chloride or rubber, the soil removing effect is not easily lowered even if the earth removing member 155 is slightly damaged in contact with the farm scene. The period until 155 becomes unusable becomes longer.

本発明の第三実施形態にかかる根菜類収穫機は、タッピング装置にＨＳＴからの駆動力を伝動するタッピング装置伝動手段１６０を設ける。このタッピング装置伝動手段１６０は、伝動軸３６の代わりに、又は伝動軸３６に直列に設ける歯車伝動装置であり、タッピング装置の正転と逆転とを切り替える伝動切替装置を備えている。図８は歯車伝動装置であるタッピング装置伝動手段１６０の内部の斜視図である。   The root crop harvesting machine according to the third embodiment of the present invention is provided with tapping device transmission means 160 for transmitting a driving force from the HST to the tapping device. The tapping device transmission means 160 is a gear transmission provided in place of the transmission shaft 36 or in series with the transmission shaft 36, and includes a transmission switching device that switches between normal rotation and reverse rotation of the tapping device. FIG. 8 is a perspective view of the inside of the tapping device transmission means 160 which is a gear transmission.

タッピング装置伝動手段１６０は、ＨＳＴからの回転動力を受ける入力回転体１６２と、この入力回転体１６２と噛み合って回転し、回転自在な構成である自由回転体１６３と、入力回転体１６２又は自由回転体１６３のいずれか一方と噛み合って回転する出力回転体１６４と、から構成する。   The tapping device transmission means 160 includes an input rotator 162 that receives rotational power from the HST, a free rotator 163 that rotates in mesh with the input rotator 162, and an input rotator 162 or a free rotation. An output rotating body 164 that meshes with one of the bodies 163 and rotates.

入力回転体１６２は、１本の鉛直方向の回転軸に対して、上下に二つの歯車を固定する。即ちＨＳＴからの回転動力により二つの歯車は、回転軸と同じ回転数で回転する。自由回転体１６３は、入力回転体１６２の軸心と平行な軸心を有する回転軸を備え、入力回転体１６２を構成する歯車の一つと噛み合う歯車をこの回転軸に固定し、回転軸の両端を軸受で受けることにより回転自在な構成となる。出力回転体１６４は、入力回転体１６２の軸心と平行な軸心を有する回転軸を備え、この回転軸にはオス側のスプラインが加工されている。このスプラインに嵌装する歯車を設け、スプラインに沿ってこの歯車が上下自在に動作可能とすると共に、回転軸と歯車は一体として回転する。出力回転体１６４は、タッピング装置の入力側と接続して、回転動力を伝達する。   The input rotating body 162 fixes two gears up and down with respect to one vertical rotation axis. That is, the two gears rotate at the same rotational speed as the rotation shaft by the rotational power from the HST. The free rotating body 163 includes a rotating shaft having an axis parallel to the axis of the input rotating body 162, and a gear meshing with one of the gears constituting the input rotating body 162 is fixed to the rotating shaft, and both ends of the rotating shaft are fixed. It becomes a structure which can be rotated freely by receiving with a bearing. The output rotating body 164 includes a rotating shaft having an axis parallel to the axis of the input rotating body 162, and a male spline is processed on the rotating shaft. A gear fitted to the spline is provided so that the gear can move up and down along the spline, and the rotating shaft and the gear rotate as a unit. The output rotating body 164 is connected to the input side of the tapping device and transmits rotational power.

タッピング装置伝動手段１６０には、出力回転体１６４を入力回転体１６２もしくは自由回転体１６３と噛み合わせることで、タッピング装置の正転と逆転とを切り替える伝動切替装置を備える。伝動切替装置は、出力回転体１６４の歯車を下方に付勢するコイルばねである付勢部材１６５と、このコイルばねの付勢力に抗して出力回転体１６４の歯車を押し上げる、「く」の字型の押上部材１６５と、この押上部材１６６の端部と接続して押上部材１６６を操作する切替操作レバー１６７とから構成する。「く」の字型の押上部材１６５は、曲折点に回動軸心を設け、その回動軸心を中心に回動すると、押上部材１６５の一端が中間部材を介して歯車を上方向へ移動させる。なお中間部材も「く」の字型で、曲折点に回動軸心を設けている。押上部材の他端は切替操作レバー１６７とワイヤーにより接続され、この切替操作レバー１６７は操縦座席１１の側部に設けているので、作業者が操縦座席１１に着席しながら切替操作レバー１６７を操作して出力回転体１６４の歯車を上下に動かし、この歯車を、入力回転体１６２を構成する歯車、もしくは自由回転体１６３を構成する歯車と噛み合わせる。入力回転体１６２を構成する歯車と噛み合うと、タッピング装置は正転をし、通常の引抜時の動作を行う。自由回転体１６３を構成する歯車と噛み合うと、タッピング装置は逆転し、引抜時とは逆方向に動作を行う。   The tapping device transmission means 160 includes a transmission switching device that switches the normal rotation and reverse rotation of the tapping device by engaging the output rotator 164 with the input rotator 162 or the free rotator 163. The transmission switching device includes a biasing member 165 that is a coil spring that biases the gear of the output rotating body 164 downward, and pushes up the gear of the output rotating body 164 against the biasing force of the coil spring. It comprises a letter-shaped push-up member 165 and a switching operation lever 167 that is connected to the end of the push-up member 166 and operates the push-up member 166. When the "<"-shaped push-up member 165 is provided with a pivot axis at the bending point and pivots about the pivot axis, one end of the push-up member 165 moves the gear upward through the intermediate member. Move. The intermediate member also has a “<” shape and has a pivot axis at the bending point. The other end of the push-up member is connected to the switching operation lever 167 by a wire. Since this switching operation lever 167 is provided on the side of the control seat 11, the operator operates the switching operation lever 167 while sitting on the control seat 11. Then, the gear of the output rotator 164 is moved up and down, and this gear meshes with the gear constituting the input rotator 162 or the gear constituting the free rotator 163. When meshed with the gears constituting the input rotating body 162, the tapping device performs normal rotation and performs a normal pulling operation. When meshed with the gears constituting the free rotating body 163, the tapping device rotates in the reverse direction and operates in the direction opposite to that during pulling.

なお、本実施形態においては、タッピング装置を構成するすべての機械要素が逆転するように構成したが、ＨＳＴからの駆動力を分岐させ、排葉搬送装置６５のみを逆転するように構成しても問題ない。   In the present embodiment, all the mechanical elements constituting the tapping device are configured to be reversed. However, the driving force from the HST may be branched to configure only the leaf transport device 65 to be reversed. no problem.

タッピング装置に駆動力を伝動するタッピング装置伝動手段１６０に、タッピング装置の正転と逆転とを切り替える伝動切替装置を設けたことにより、タッピング装置に茎葉部や土砂が詰まった場合でも、タッピング装置を逆転運転させることで茎葉部や土砂を容易に排出できる。   The tapping device transmission means 160 for transmitting the driving force to the tapping device is provided with a transmission switching device for switching between normal rotation and reverse rotation of the tapping device, so that the tapping device can be used even when foliage or earth and sand are clogged. By making it run in reverse, the foliage and soil can be easily discharged.

上記のように、茎葉部や土砂を容易に排出できることから、詰まった茎葉部等を除去するためにタッピング装置を分解するという作業をする必要がなくなり、作業能率が向上する。   As described above, since the foliage part and earth and sand can be easily discharged, it is not necessary to disassemble the tapping device in order to remove the clogged foliage part and the like, and the work efficiency is improved.

伝動切替装置が、出力回転体１６４を、入力回転体１６２もしくは自由回転体１６３と噛み合わせることで、前記タッピング装置の正転と逆転とを切り替えることにより、逆転運転による茎葉部や土砂の除去作業を容易にでき、作業能率が向上する。   The transmission switching device meshes the output rotator 164 with the input rotator 162 or the free rotator 163 to switch between the normal rotation and the reverse rotation of the tapping device, thereby removing the foliage and earth and sand by the reverse rotation operation. Work efficiency is improved.

伝動切替装置を、出力回転体１６４を下方に付勢する付勢部材１６５と、この付勢部材１６５の付勢力に抗して出力回転体１６４を押し上げる押上部材１６６と、この押上部材１６６を操作する切替操作レバー１６７とから構成したことにより、切替操作レバー１６７を操作して押上部材１６６を操作し、付勢部材１６５の付勢力に抗して押上部材１６６が出力回転体１６４を押し上げてタッピング装置を逆回転させるので、作業者がタッピング装置から離れた位置で伝動切替装置を操作できるので、作業性がよく作業能率が向上する。   The transmission switching device includes an urging member 165 that urges the output rotator 164 downward, a push-up member 166 that pushes up the output rotator 164 against the urging force of the urging member 165, and operates the push-up member 166. Since the switching operation lever 167 is operated, the switching operation lever 167 is operated to operate the push-up member 166, and the push-up member 166 pushes up the output rotating body 164 against the urging force of the urging member 165 and performs tapping. Since the device is rotated in the reverse direction, the operator can operate the transmission switching device at a position away from the tapping device, so that workability is good and work efficiency is improved.

また出力回転体１６４を付勢部材１６５で下方に付勢しているので、切替操作レバー１６７の操作を止めると出力回転体１６４が元の位置にもどり、タッピング装置が通常方向へ作動する伝動構成に自動的に復帰するので、出力回転体１６４を逆転位置にしたまま収穫作業を行うことを防止できる。   Further, since the output rotator 164 is urged downward by the urging member 165, when the operation of the switching operation lever 167 is stopped, the output rotator 164 returns to the original position and the tapping device operates in the normal direction. Therefore, it is possible to prevent the harvesting operation from being performed while the output rotator 164 is in the reverse rotation position.

他の実施の形態として、上記出力回転体１６４の上方にこの出力回転体１６４を回転させるためのハンドルを設けることも可能である。この場合、伝動切替装置により出力回転体１６４を、入力回転体１６２及び自由回転体１６３のいずれにも噛み合わない位置に移動させ作業者が操縦座席１１からハンドルを回して出力回転体１６４を逆転させる。   As another embodiment, a handle for rotating the output rotator 164 may be provided above the output rotator 164. In this case, the output rotator 164 is moved to a position where it does not mesh with either the input rotator 162 or the free rotator 163 by the transmission switching device, and the operator turns the handle from the control seat 11 to reverse the output rotator 164. .

The wind generator 172 provided above the remaining leaf processing conveyor 76 is driven by the driving force. The wind raising device 172 removes dust on the remaining leaf processing conveyor 76. The driving force to the wind generator 172 is transmitted from the remaining leaf processing transmission case 170 by a blower transmission case 171 having a bevel gear pair. Further, the wind generator 171 rotates while swinging left and right using a swing mechanism configured by a link mechanism as shown in FIG. 11, for example.

残葉処理コンベア７６上の土砂や茎葉部を搬送風で除去する起風装置１７２を設けたことにより、作業者に土砂や茎葉部が飛散するのを防止できる。   By providing the wind-up device 172 that removes the earth and sand and the foliage on the remaining leaf processing conveyor 76 with the conveying air, it is possible to prevent the earth and sand and the foliage from scattering to the operator.

また、起風装置１７２が、残葉処理ローラ７５の駆動力と同じ駆動元から駆動力を受けて運転されることにより、既存の装置から駆動力を得ることができ、部品点数を削減することができる。   Further, the driving device 172 is operated by receiving the driving force from the same driving source as the driving force of the remaining leaf processing roller 75, so that the driving force can be obtained from the existing device and the number of parts can be reduced. Can do.
