Description
【考案の詳細な説明】 (イ)産業上の利用分野 本考案は液状肥料用の施肥機における導液装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a liquid transfer device in a fertilizer applicator for liquid fertilizer.
(ロ)従来技術 従来、走行車の後部に施肥装置をリンクを介して昇降可
能に装着し、機体に取付けた肥料タンク内の液状肥料を
低圧ポンプとホースで施肥装置に圧送するようにした施
肥機は既に知られている。(B) Conventional technology Conventionally, a fertilizer application was attached to the rear part of a traveling vehicle so that it could be moved up and down via a link, and liquid fertilizer in a fertilizer tank attached to the machine was pumped to a fertilizer application by a low pressure pump and a hose. The machine is already known.
この施肥機は低圧ポンプを用いていたので、サクション
ホースは勿論のこと吐出ホースをも軟質のものを使用す
ることができ、それにより施肥装置を機体に対して昇降
させた時、吐出ホースは施肥装置の昇降に順応して無理
なく屈伸した。Since this fertilizer applicator used a low pressure pump, not only the suction hose but also the discharge hose can be soft, so that when the fertilizer applicator is moved up and down with respect to the machine, Adapted to the lifting and lowering of the device, and flexed comfortably.
しかし、低圧ポンプでは液状肥料の粘度の大小、その他
の要因により吐出量が不安定になり、施肥量が変動する
問題を有していた。However, the low-pressure pump has a problem that the amount of fertilizer applied varies depending on the viscosity of liquid fertilizer and other factors, which makes the discharge rate unstable.
このような問題点を解決すべく本出願人は高圧ポンプを
用いた施肥機を開発し特開昭61−249307号公報により公
開されている。In order to solve such a problem, the present applicant has developed a fertilizer applicator using a high-pressure pump and has disclosed it in Japanese Patent Laid-Open No. 61-249307.
(ハ)考案が解決しようとする問題点 しかしながら、前記既知の施肥機は高圧ポンプが用いて
あるので施肥装置に通ずる流路管内に詰りを生ずると、
吐出ホース内が異常な高圧となり軟質ホースでは破損す
るという新たな問題点が発生した。(C) Problems to be solved by the device However, since the known fertilizer applicator uses a high-pressure pump, if a clogging occurs in the flow passage pipe leading to the fertilizer applicator,
There was a new problem that the pressure inside the discharge hose became abnormally high and the soft hose was damaged.
そこで、吐出ホースを強度が大なる耐圧性の優れた硬質
ホースにすると共にポンプの吐出口から略ストレートに
延出させたところ上記問題点を解決することはできた
が、施肥機を機体回行時等に昇降させた時、吐出ホース
はその変形量が小さいために折れたり、吐出口との連結
部が抜けたりする現象が発生した。Therefore, when the discharge hose was made a hard hose with high strength and excellent pressure resistance and it was extended almost straight from the discharge port of the pump, it was possible to solve the above problem, but the fertilizer applicator traveled around the machine body. When the hoses were lifted up or down at times, the deformation of the discharge hose was small, and there was a phenomenon that the discharge hose was broken or the connecting portion with the discharge port was pulled out.
また、吐出ホースの前端部をポンプの吐出口に着脱する
とき、剛直な吐出ホースが前後方向になるため、撓ませ
難く、着脱操作が困難になるという更に新たな問題点が
発生した。Further, when the front end portion of the discharge hose is attached to or detached from the discharge port of the pump, the rigid discharge hose is in the front-back direction, so that it is difficult to bend and the attachment / detachment operation becomes more difficult.
(ニ)問題点を解決するための手段 本考案は、走行車の機体1の後部に施肥装置をアッパー

ホースで構成することにより、前述の問題点を解決し
た。(D) Means for Solving the Problems In the present invention, a fertilizer application device is attached to a rear portion of a machine body 1 of a traveling vehicle so as to be able to move up and down by a link mechanism composed of an upper link and a lower link, and In a fertilizer applicator in which a pump 15 communicating with the fertilizer tank 13 is located below the lower link attachment part, and the pump 15 and the fertilizer applicator are connected by a hose, a discharge port directed rearward of the pump 15
The discharge hose 18 connected to 15a has its front end in the front-rear direction, and is bent upward in the subsequent portion to rise up to the upper position of the lower link, and the rear of this rising portion is used as the fertilizer application device. The above-mentioned problem was solved by connecting to the fertilizer pipe 22 and by curving in advance so as to maintain the above-mentioned constant shape, and by forming the rising portion with a hard hose capable of tilting and deforming in the front-rear direction.
(ホ)作用 肥料タンクに液状肥料を注入してポンプを駆動しながら
機体を前進させると、肥料タンク内の液状肥料はポンプ
で吸入され、吐出ホースに圧出された液状肥料は施肥装
置により施肥される。このような施肥作業中ポンプの吐
出圧を高圧にすることで液状肥料の硬質又は圃場条件等
の如何に拘らず略一定の安定した施肥を行なうことがで
きる。(E) Action When liquid fertilizer is injected into the fertilizer tank and the machine is advanced while driving the pump, the liquid fertilizer in the fertilizer tank is sucked in by the pump, and the liquid fertilizer extruded to the discharge hose is fertilized by the fertilizer application device. To be done. By making the discharge pressure of the pump high during such fertilization work, substantially constant and stable fertilization can be performed regardless of the hardness of the liquid fertilizer or the field conditions.
そして、一行程の施肥が終わって機体を回行させるべ
く、施肥装置をリンク機構の回動で上昇させると、吐出
ホースも上昇傾動する。Then, when the fertilizer application is raised by the rotation of the link mechanism so that the machine body is rotated after the fertilizer application for one stroke is completed, the discharge hose is also tilted upward.
その際、吐出ホースは硬質であるが、この吐出ホースは
一定の形状を保つようにあらかじめ湾曲成型されてお
り、その前端部は前後方向としそれに続く部分を起点と
して湾曲しロアリンクの上方位置まで立上り部が成型さ
れているので、ロアリンクが上昇回動してもこの立上り
部が前後に緩やかに無理なく変形し、吐出ホースが途中
で折れたり連結部が抜けたりすることがない。At that time, the discharge hose is rigid, but this discharge hose is pre-curved and molded to maintain a constant shape, and its front end is in the front-rear direction and the part following it is curved to the upper position of the lower link. Since the rising portion is molded, even if the lower link is rotated upward, the rising portion is gently deformed forward and backward without causing the discharge hose to be broken or the connecting portion to be pulled out.
また、吐出ホースの前端部をポンプの吐出口に嵌装する
時、前記立上り部が成型されていることにより吐出ホー
スが前後に撓み易いので、同じく前後方向に向かうよう
に成型された前端部を容易に前後進退させて装着した
り、又は抜き取ったりすることが吐出ホースの折れなど
の抵抗を受けることなく軽快にできる。Further, when the front end of the discharge hose is fitted into the discharge port of the pump, the discharge hose is easily bent back and forth due to the molding of the rising portion. It can be easily moved back and forth to be attached or removed without being subjected to resistance such as breakage of the discharge hose.
