Description

【０００１】
【発明の属する技術分野】
本発明は、主として馬鈴薯等の芋類を芽が残るように小さく切断して栽培用の種芋を連続的に得る農作物連続切断装置に関する。
【０００２】
【従来の技術】
従来、馬鈴薯等の芋類の栽培においては、種子として通常の大きさに生育した種芋を所定の大きさに切断して畑に植える農法が確立しており、農家は植え付け時期になると一個一個種芋を包丁等の刃物を使用して手作業で切断している。
ところで、種芋には発芽する芽が頭上から発芽し易い順序で一番芽，二番芽という具合に螺旋状に配置されているので、切断後の種芋には必ず発芽に優位な芽が残るように確認しながら切断する必要がある。また、種芋は高価であるから、経済的効果を考慮して二つ切りや四つ切りなど種芋の大きさや芽の数に応じて異なる切り方をする必要もある。
そこで、出願人はこのような問題点に鑑み、無端の送りコンベアに農作物を保持して搬送する保持台を所定間隔をおいて複数設け、送りコンベアの所定位置の上方に刃物を昇降自在に設け、刃物の下方に保持台が到来したときに刃物を送りコンベアの搬送方向に移動しながら下降させて保持台上の農作物を切断し切断後上昇させる昇降手段を設け、農作物を送りコンベアで搬送しながら連続的に切断できるようにした農作物連続切断装置を開発し、実用に供している。
しかしながら、この装置において四つ切りの場合、図９に示すように昇降手段の駆動部から刃物２１まで距離があるため、駆動部の若干の遊びにより刃物２１が搬送方向と直交する方向に大きくブレ、農作物Ｐを正確な位置で切断することが難しかった。また、農作物は保持台に載置しているだけであるから、搬送中の振動や刃物の接触時にズレたりして同様に正確な位置で切断することが難しかった。
【０００３】
【発明が解決しようとする課題】
本発明が解決しようとする課題は、従来のこれらの問題点を解消し、馬鈴薯等の芋類を栽培用の種芋に切断する作業を手作業に代わって連続的に効率良く行え、しかも正確な位置で切断できるようにした農作物連続切断装置を提供することにある。

【作用】
本発明では、農作物を保持台上に載置して送りコンベアで搬送し、刃物の下方に保持台が到来すると、昇降手段は刃物を送りコンベアの搬送方向に移動しながら下降させて保持台上の農作物を切断する。切断後は刃物を上昇させて下降前の位置に復帰する。ここで、刃物は同期手段により送りコンベアと正確に連動しながら下降するとともに横ブレ防止手段により搬送方向と直交する方向への横ブレを防止しながら農作物を正確な位置で切断する。
保持台が弾力性を示す挟持片を備えた複数本の部材で構成されたものは、農作物を各挟持片でズレなく挟持し、より正確な位置で切断できるようにする。
【０００６】
【発明の実施の形態】
本発明の同期手段としては、昇降手段の部材に一対の小アームの一端をそれぞれ枢着し、同一対の小アームの他端に下部に刃物を設けた刃物吊設体を水平を保持するように枢着し、刃物吊設体に刃物の下降時に送りコンベアの保持台近傍の部材に掛止する掛止棒を設け、掛止棒で送りコンベアと刃物の同期を行わせるようにしたものが用いられ、横ブレ防止手段としては保持台近傍の部材の掛止棒が掛止する部分に掛止棒を挟持するように所定間隔をおいた一対のガイドを設け、掛止棒をガイド間に掛止させることで切断時の横ブレを防止できるようにする。保持台としては、下降する刃物が板材間を通過できるように複数本の細長い板材を所定間隔おいて放射状に立設し、各板材の途中から上部を中心に向けて下方に折曲して弾力性を有する挟持片いわゆる板バネを形成したものが一般的に用いられるが、その他スプリングを用いたもの等農作物をズレなく挟持できるものは全て採用できる。
昇降手段は送りコンベアの幅方向に複数並設した保持台の数だけ設けてもよく、その場合刃物を同時に下降させず交互に下降するように構成すると、回転運動が円滑となり好ましい。
送りコンベアと昇降手段の駆動は一つのモータで行うのが望ましく、モータの出力軸をそれぞれ昇降手段のアームの一端と送りコンベアの駆動車にそれぞれチェーン等で連結して伝達し、送りコンベアと昇降手段が誤差なく同期して作動できるようにする。

また、挟持台４を構成する各板材４ａの上部に弾力性を示す挟持片４ｂを形成したから、農作物Ｐを確実に保持でき、搬送中の振動や刃物の接触時にズレたりすることなくより正確な位置で切断できる。
【００１２】

The cutter suspension body 7b is provided with a substantially L-shaped latch bar 7c on the conveying direction side of the feed conveyor 2, and the latch bar 7c is latched between the guides 3a and comes into contact with the front end of the slat 2a. Can be accurately synchronized with the movement of the feed conveyor 2 without lateral displacement.
8 is a motor, 8a is an output shaft of the motor 8, 9 is a cover, 10 is a support leg, 11 is a caster, 12 is a handle, 13 is a container, and P is a crop.
[0010]
In the present embodiment, first, the position of the sprout is confirmed by a human hand, and the crop P is sandwiched on the sandwiching table 4 and conveyed by the feed conveyor 2 from the right side as shown in FIG. The elevating means 6 is lowered in the same direction and at the same speed as the feed conveyor 2 by rotating the arm 6a so as to be interlocked with the feed conveyor 2 by the motor 8, and the cutter 6c starts to cut the crop P.
Next, as shown in FIG. 8B, the lifting means 6 completely cuts the crop P while rotating as a whole in synchronization with the feed conveyor 2 until it reaches the lowest position. At this time, as shown in FIG. 6, the latch bar 7c is latched between the guides 3a of the feed conveyor 2 in the middle of the lowering, and rotates in synchronism with the feed conveyor 2 without being laterally shaken while being in contact with the front end of the slat 2a. , Cut the crop P at an accurate position.
Next, as shown in FIG. 8C, after the lifting means 6 is cut, the blade 6c is separated from the crop P and the retaining rod 7c is also separated from the guide 3a.
Then, as shown in FIG. 8 (d), the crop P is transported to the left and falls into the container 13, and the blade 6 c is returned to the original position by the elevating means 6.
The elevating means 6 continues the rotational movement as it is, starts descending again, and continuously cuts the crops P that are sequentially conveyed, and this is repeated at a constant speed.
[0011]
In this embodiment, since it is configured as described above, the latch bar 7c is accurately latched by the pressing of the front end of the slat 2a while being held so as to be sandwiched between the guides 3a. It can always cut at an accurate position, and can efficiently obtain a soy seed having excellent quality.
Moreover, since the holding piece 4b which shows elasticity is formed in the upper part of each board | plate material 4a which comprises the holding stand 4, the crop P can be hold | maintained reliably, and it is more accurate, without shifting | deviating at the time of the vibration during conveyance, or contact with a blade. Can be cut at any position.
