上記目的の達成のために本考案は、根菜の葉部を挟持して該根菜を地中から引 き抜きつつ上方に引き上げる引抜き部と、左右一対の無端回動帯とこれの下方に 配置される左右一対のガイド機構とから成り、その葉部の下部を一対のガイド機 構間で誘導案内しながら、葉部の上部を一対の無端回動帯の駆動によって挟持移 送することにより、引抜き部から送られてくる根菜を後方に搬送する搬送装置と を夫々設け、一対の無端回動帯と一対のガイド機構との上下間隔が、搬送方向下 手側に行くほど広くなる後広がり姿勢となるように、これら無端回動帯とガイド 機構とを相対配置するとともに、搬送根菜に所定以上の下方移動力が作用すると 、該根菜の無端回動帯からの下方へのずれ動きが許容されるように、一対の無端 回動帯による根菜葉部に対する挟持力を設定し、さらに、無端回動帯又はガイド 機構を上下揺動可能として後広がり姿勢の広がり角度を調節可能に構成してある ことを特徴とするものである。 In order to achieve the above object, the present invention is provided with a pulling-out portion for sandwiching a root part of a root vegetable and pulling the root vegetable upward from the ground, a pair of left and right endless rotation bands, and a lower part thereof. It is composed of a pair of left and right guide mechanisms that guide and guide the lower part of the leaf between the pair of guide mechanisms, while the upper part of the leaf is pinched and moved by the drive of a pair of endless rotation bands, so that it can be pulled out. Each of them is provided with a transport device for transporting root vegetables sent from the rear part, and the vertical interval between the pair of endless swivel bands and the pair of guide mechanisms becomes wider toward the lower side in the transport direction. As described above, when the endless rotation band and the guide mechanism are arranged relative to each other, and the downward movement force of a predetermined amount or more acts on the transport root vegetables, the downward movement of the root vegetables from the endless rotation band is allowed. As shown in Fig. Set clamping force against leaf, furthermore, is characterized in that are adjustably configured spread angle of the rear spread posture endless rotary Dotai or guide mechanism as be able to swing vertically.
【0005】[0005]
引抜き部は、地上に突出している葉部を挟持することで地中にある根菜を引き 抜いて上方に持ち上げるように機能し、搬送装置は、一対のガイド機構によって 葉部の下部の搬送経路を形成した状態で、一対の後部無端回動帯による葉部上部 を挟持しての搬送作用を与える機能を発揮する。 搬送装置では、ガイド機構と後部無端回動帯との上下間隔が、搬送方向下手側 に行くほど広くなるように、かつ、一対の後部無端回動帯では根菜の下方移動が 許容されるようにしてあるから、後方への搬送に従ってガイド機構は葉部の根元 に近づき、ついには根菜本体上面に接触した状態で搬送される接触搬送状態にな り、それ以後では一対の後部無端回動帯と葉部とが上下に相対移動して接触搬送 状態が維持されるようになる。その結果、この搬送装置の終端では、どの根菜も 接触搬送状態に統一されるようになり、根菜を一定の姿勢・位置でもって葉部を 切断するカッター装置等の後処理工程に受渡しできるようになる。 そして、ガイド機構と後部無端回動帯との後広がり角度を調節可能であるから 、根菜の品種や成育状態に合わせて葉部の扱き長さを調節するべくガイド機構と 後部無端回動帯との間隔を設定することができるようになる。 The pull-out part functions to pull out the root vegetables in the ground and lift them upward by sandwiching the leaves protruding above the ground, and the transfer device uses a pair of guide mechanisms to move the transfer path below the leaves. In the formed state, it exerts a function of holding the upper portion of the leaf portion by a pair of rear endless rotation bands and giving a conveying action. In the transporting device, the vertical distance between the guide mechanism and the rear endless swivel band becomes wider toward the lower side in the transport direction, and the downward movement of root vegetables is allowed in the pair of rear endless swivel bands. Therefore, the guide mechanism approaches the root of the leaf portion as it is conveyed backward, and finally comes into a contact conveyance state in which it is conveyed in contact with the upper surface of the root vegetable body. The leaf part moves up and down relative to each other, and the contact conveyance state is maintained. As a result, at the end of this transfer device, all root vegetables will be unified into a contact transfer state, so that the root vegetables can be delivered to the post-treatment process such as a cutter device that cuts the leaves at a fixed posture and position. Become. Since the back spread angle between the guide mechanism and the rear endless swivel belt can be adjusted, the guide mechanism and the rear endless swivel belt can be adjusted to adjust the handling length of the leaves according to the variety and growing condition of the root vegetables. You will be able to set the interval.
【0006】[0006]
従って、根菜の地中からの引抜きからカッター装置等の後処理の手前までの一 連の工程を機械化できたとともに、後処理に受け渡す根菜をその品種や成育の如 何に拘らずに一定姿勢・位置に揃えることによる機械化処理の円滑・安定化が図 れ、収穫能率向上に寄与しながら労力を軽減させることができた。 Therefore, it was possible to mechanize a series of processes from the extraction of root vegetables from the ground to the front of post-treatment such as a cutter device, and the root vegetables to be passed to the post-treatment could be fixed regardless of their variety or growth.・ By aligning the positions, the mechanization process was smooth and stable, and the labor was reduced while contributing to the improvement of harvest efficiency.

以下に、本考案の実施例を図面に基づいて説明する。 図1に本考案による根菜類用収穫機の全体側面図が、図7にその前部の平面図 が夫々示され、1は引抜き部、2は搬送装置、3は葉切り装置、4は収穫部、5 はクローラ走行装置、6は操縦部である。 引抜き部1は、左右一対の分草具7,7を先端に備えるとともに、分草具7の 直後部位と葉切り装置3部位とに亘るコンベヤ式の挟持コンベヤ装置9を装備し て構成されている。挟持コンベヤ装置9は、後上り傾斜姿勢で対向配置して駆動 される左右一対の搬送ベルト11,11で構成されている。 搬送装置2は、前述した左右一対の搬送ベルト11,11とこれの下方に配置 される左右一対のガイド機構12,12とから構成され、根菜葉部の下部を一対 のガイド機構12,12間で誘導案内しながら、葉部の上部を一対の搬送ベルト 11,11の駆動によって挟持移送することにより、引抜き部から送られてくる 根菜を後方に搬送する機能を持っている。 An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 shows the whole side view of a root vegetable harvester according to the present invention, and Fig. 7 shows a plan view of the front part thereof. 1 is a pulling part, 2 is a conveying device, 3 is a leaf cutting device, and 4 is a harvesting device. Reference numeral 5 is a crawler traveling device, and reference numeral 6 is a control section. The pull-out section 1 is provided with a pair of left and right weeding tools 7, 7 at the tip, and is equipped with a conveyor-type nipping conveyor device 9 that extends immediately after the weeding tool 7 and the leaf cutting device 3 site. There is. The sandwiching conveyor device 9 is composed of a pair of left and right conveyor belts 11 and 11 that are driven while facing each other in a rearwardly inclined posture. The transport device 2 is composed of the above-mentioned pair of left and right transport belts 11 and 11 and a pair of left and right guide mechanisms 12 and 12 arranged below the transport belts 11, and the lower part of the root and vegetable leaf portion is provided between the pair of guide mechanisms 12 and 12. While guiding and guiding with, the upper part of the leaf is pinched and transferred by driving a pair of conveyor belts 11, 11 to have a function of conveying the root vegetables sent from the pulling section backward.
【0008】 ガイド機構12は、図4、図5に示すように、チェンリンク13毎に横軸心Y 周りに回動自在なローラ14が装備されたチェン15で構成されている。ローラ 14は、バネ16によって外方に向けての付勢力が発生可能な状態でチェンリン ク13に取付けられ、従って、根菜の葉部は対向する左右のローラ14,14で 挟持されての後方移送力を受けるのであり、その移送速度は、搬送ベルト11に よる速度とほぼ同じである。そして、搬送ベルト11とガイド機構12との上下 間隔を、搬送方向下手側に行くほど広くなる後広がり姿勢となるようにガイド機 構12の後上がり傾斜角度を極緩いものに初期設定されている。 また、図1に示すように、ガイド機構12は、その前部に設けた左右向きの支 点P周りで揺動昇降調節及び固定維持が自在に構成されており、前記後広がり姿 勢の広がり角度θの調節設定により、種々の品種(例えば、人参と大根等)や成 育状態の違い等によって異なる葉部の長さに対応できるように構成してある。As shown in FIGS. 4 and 5, the guide mechanism 12 is composed of a chain 15 in which each chain link 13 is equipped with a roller 14 which is rotatable around the horizontal axis Y 1. The roller 14 is attached to the chain 13 in a state where a spring 16 can generate an outward urging force. Therefore, the root portion of the root vegetables is nipped by the left and right rollers 14 and 14 which face each other, and is transferred backward. It receives a force, and its transfer speed is almost the same as the speed by the conveyor belt 11. Further, the vertical distance between the conveyor belt 11 and the guide mechanism 12 is initially set to be a very gentle rearward inclination angle of the guide mechanism 12 so that the conveyor belt 11 and the guide mechanism 12 have a rearwardly widened posture that becomes wider toward the lower side in the conveying direction. . Further, as shown in FIG. 1, the guide mechanism 12 is configured such that it can freely swing and ascend / descend and maintain fixed around a fulcrum P that is provided on the front portion thereof in the left-right direction. By adjusting the angle θ, different leaf lengths can be accommodated depending on various varieties (for example, carrot and radish) and differences in growth conditions.
【0009】 詳述すると、図1、図2に示すように、ガイド機構12のやや後部寄りの位置 に根菜本体の上面に接触して作動するボリューム式の首揃えセンサ22を設ける とともに、ガイド機構12を駆動揺動させるアクチェータ(油圧シリンダやモー タによる電動シリンダ等)23と制御装置24とを設けて、自動首揃え制御装置 Aを構成してある。首揃えセンサ22は、揺動移動自在な接触子22aを所定揺 動範囲aでの最も下側の位置に向けて下方付勢してあり、所定揺動範囲aよりも 上方に揺動する場合と、一定時間以上接触子22aが接触作動しない場合とが異 常とみなすように回路設定してある。 自動首揃え制御装置Aの作用を説明すれば、搬送根菜の本体上面に接触子22 aが接触して所定揺動範囲a内で揺動移動する場合にはガイド機構12の広がり 角度θが適正であるのでアクチェータ23は作動せずに現状の角度が維持される 。接触子22aが所定揺動範囲a以上に上方揺動すると、ガイド機構12が下が り過ぎであると判断して広がり角度θが狭くなるようにアクチュエータ23を駆 動させるとともに、接触子22aが一定時間以上動かない場合にはガイド機構1 2が上がり過ぎであると判断して広がり角度θが広くなるようにアクチュエータ 23を駆動させるように制御されるのである。尚、26は自動制御の入切りスイ ッチであり、スイッチ切りによって操作レバー27による人為揺動昇降操作が行 えるようになる。 また、図3に示すように、ガイド機構12の下端側スプロケット25の対向部 分には一対のガイド部材21,21が装備してあり、根菜の導入口の幅を広めて ある。More specifically, as shown in FIGS. 1 and 2, a volume type neck alignment sensor 22 that operates by contacting the upper surface of the root vegetable body is provided at a position slightly rearward of the guide mechanism 12, and the guide mechanism is also provided. An automatic neck justification control device A is configured by providing an actuator (a hydraulic cylinder, an electric cylinder by a motor, or the like) 23 for driving and rocking 12 and a control device 24. The neck alignment sensor 22 biases the contact 22a, which is swingable, to the lowermost position in the predetermined swing range a, and swings above the predetermined swing range a. The circuit is set so that it is considered to be abnormal when the contactor 22a does not operate for a certain period of time. The operation of the automatic neck alignment control device A will be described. When the contact 22a comes into contact with the upper surface of the main body of the transport root vegetable and swings within the predetermined swing range a, the spread angle θ of the guide mechanism 12 is appropriate. Therefore, the actuator 23 does not operate and the current angle is maintained. When the contact 22a is swung upwards beyond the predetermined swing range a, it is determined that the guide mechanism 12 is too low, and the actuator 23 is driven so that the spread angle θ becomes narrower. When it does not move for a certain time or longer, it is determined that the guide mechanism 12 has moved up too much, and the actuator 23 is controlled so as to drive the spread angle θ wider. Reference numeral 26 denotes an automatic control on / off switch, and by turning the switch off, an artificial rocking / lowering operation can be performed by an operating lever 27. Further, as shown in FIG. 3, a pair of guide members 21 and 21 are provided in the facing portion of the lower end side sprocket 25 of the guide mechanism 12, and the width of the root vegetable inlet is widened.
【0010】 図6に示すように、左右の搬送ベルト11,11には、これらを互いの存在方 向に押圧して葉部の挟持力を発生させるための多数の転輪17が設けられ、前端 部からガイド機構12の前端に相当する部位までの搬送ベルト前部11aにおい ては、地中の根菜を確実に引き抜けるべく強い挟持力が作用するように転輪17 の付勢スプリング8の強さを設定し、かつ、それから後側の搬送ベルト後部11 bにおいては葉部の挟持力を,搬送ベルト前部11aにおけるスプリング8より も細いスプリング10の採用によって弱いものに設定してある。 そして、ガイド機構12の後方位置には、根菜の葉部を切り落とす回転カッタ ー18を上下位置の調節が自在な状態で設けて成る葉切り装置3が配設されると ともに、ガイド機構12と葉切り装置3との間に、根菜の吊下げ姿勢を葉切り装 置3での切断作動に適した状態に矯正できるように、ガイド機構12から送られ てくる根菜の葉部を持ち直して葉切り装置3へ移送する姿勢矯正搬送機構19を 介在してある。姿勢矯正搬送機構19は左右一対の搬送ベルト20,20で構成 されており、これと葉切り装置3とはガイド機構12に支持されて一体に揺動移 動調節される。As shown in FIG. 6, the left and right conveyor belts 11 and 11 are provided with a large number of rolling wheels 17 for pressing them in the mutually existing directions to generate a leaf-holding force. In the front portion 11a of the conveyor belt from the front end portion to the portion corresponding to the front end of the guide mechanism 12, the strong force of the biasing spring 8 of the roller wheel 17 is applied so that a strong clamping force acts so as to reliably pull out the root vegetables in the ground. The gripping force of the leaf portion is set to be weaker in the rear portion 11b of the conveyor belt on the rear side by using a spring 10 thinner than the spring 8 in the front portion 11a of the conveyor belt. At the rear position of the guide mechanism 12, there is provided a leaf cutting device 3 which is provided with a rotary cutter 18 for cutting off the leaves of the root vegetables in a state where the vertical position can be adjusted freely. In order to correct the hanging posture of the root vegetables to the state suitable for the cutting operation by the leaf cutting device 3 between the leaf cutting device 3 and the leaf portion of the root vegetables sent from the guide mechanism 12 to be picked up again. A posture correction transport mechanism 19 for transporting to the cutting device 3 is interposed. The posture correction transport mechanism 19 is composed of a pair of left and right transport belts 20 and 20, and this and the leaf-cutting device 3 are supported by a guide mechanism 12 and integrally swing-adjusted.
【0011】 収穫作業の主要作用を述べると、搬送ベルト前部11aによる強い挟持力でも って葉部を挟持して後方上方に持ち上げることにより、地中にある根菜を引き抜 き、次いで、搬送ベルト後部11bとガイド機構12とによる搬送力で根菜を後 方上方に移送するのであるが、前記後広がり角度θによって次第に根菜本体の上 面がローラ14に接近し、ガイド機構12後部ではローラ14に根菜本体上面が 接当した接触搬送状態になる。それから以後では、搬送ベルト後部11bの弱い 挟持力により、後方への搬送力は根菜に伝達しつつ葉部の下方へのすり抜け移動 が許容されることにより、搬送ベルト11の終端では、根菜は必ず接触搬送状態 になり、次に控える葉切り装置3用の姿勢矯正装置に対する一定姿勢・位置を維 持するようになるのである。The main operation of the harvesting work will be described. By grasping the leaf portion with a strong grasping force by the conveyor belt front part 11a and lifting it backward and upward, the root vegetables in the ground are pulled out, and then the conveyor belt is conveyed. The root vegetables are transported rearward and upward by the conveying force of the belt rear portion 11b and the guide mechanism 12, but the upper surface of the root vegetable body gradually approaches the roller 14 due to the rearward spread angle θ, and the roller 14 at the rear portion of the guide mechanism 12 is moved. The upper surface of the root vegetable body is in contact with the contact transfer state. After that, since the rearward conveying force is transmitted to the root vegetables due to the weak clamping force of the rear portion 11b of the conveyor belt, the leaves are allowed to slip through downward, so that the root vegetables are always kept at the end of the conveyor belt 11. The contact conveyance state is set, and the posture and position of the leaf cutting device 3 to be held next are maintained at a constant posture and position.
【0012】 本実施例では、一組の搬送ベルト前部11aが前部無端回動帯に、かつ、搬送 ベルト後部11bが後部無端回動帯に夫々相当しているが、夫々別構成の搬送ベ ルト、または搬送チェンで構成しても良い。 ガイド機構12としては、上記のローラ付きチェン15の他、単なる一対のガ イド棒から構成するとか、下面に左右軸心周りに回動自在な多数のローラを備え た一対のガイド部材と、これらガイド部材の直上位置において葉部を後押しして 搬送ベルト12と同速度で移送力を発生するように設けられた接当式の駆動移送 体とで構成する等も考えられる。 また、一対の搬送ベルト11を揺動昇降できるようにして後広がり角度θを可 変調節できるものや、搬送ベルト11とガイド機構12を共に揺動昇降させるも のでも良い。In the present embodiment, the pair of conveyor belt front portions 11a correspond to the front endless rotation belt, and the conveyor belt rear portion 11b corresponds to the rear endless rotation belt. It may consist of a belt or a transport chain. As the guide mechanism 12, in addition to the above-described roller-attached chain 15, a simple pair of guide rods is used, or a pair of guide members having a large number of rollers rotatable on the lower surface about the left and right axial centers, and these. It is also conceivable that the leaf portion is pushed at a position directly above the guide member and is constituted by an abutment type drive transfer member provided so as to generate a transfer force at the same speed as the transfer belt 12. Further, a pair of conveyor belts 11 can be swung up and down so that the rearward spread angle θ can be variably adjusted, or both the conveyor belt 11 and the guide mechanism 12 can be swung up and down.
