【産業上の利用分野】[Industrial applications]

本考案は、種子の栄養物質や殺菌剤を含有するゲルで種子を被覆して種子を保 護すると共に、種子をゲル被覆により球状大粒化して播種し易くする種子被覆加 工装置のゲル吐出機構に関し、特に、種子被覆の厚さを種子の種類に適応した厚 さに制御することができる種子被覆加工装置のゲル吐出機構に関する。 The present invention is a gel-discharging mechanism of a seed-coating processing device that coats seeds with a gel containing a nutrient substance and a germicide for seeds to protect the seeds and makes the seeds spherical-sized by gel-coating to facilitate sowing. In particular, the present invention relates to a gel discharging mechanism of a seed coating processing apparatus capable of controlling the thickness of seed coating to a thickness adapted to the type of seed.

【従来の技術】[Prior Art]

従来、種子はコーティングされないまま播種されるのが一般的であるが、種子 を食害から保護し、種子を播種され前に殺菌,発芽促進処理などの予備処理を行 うために種子を被覆するコーティング種子がある。 種子を連続的に効率よく被覆する従来の種子被覆加工装置としては、図5の動 作説明図に示すようなものがある。 Traditionally, seeds are generally sown without coating, but a coating that covers the seeds to protect them from feeding damage and to perform pretreatments such as sterilization and germination-promoting treatment before sowing the seeds. There are seeds. As a conventional seed coating processing apparatus for coating seeds continuously and efficiently, there is one shown in the operation explanatory diagram of FIG.

【0003】 図5(イ)に示すように、シリンダ本体1には、縦方向に貫通するプランジャ 挿入口2が設けられ、プランジャ挿入孔2の下端に、中央に向かって狭くなるテ ーパ形状の弁座3が形成され、プランジャ挿入孔2には、筒形状に形成され下端 部に弁座3に接離する弁4aを有するゲル切断プランジャ4が挿入される。As shown in FIG. 5 (a), a cylinder body 1 is provided with a plunger insertion opening 2 penetrating in the longitudinal direction, and a taper shape that narrows toward the center at the lower end of the plunger insertion hole 2. The valve seat 3 is formed, and the gel cutting plunger 4 having a valve 4a that is formed in a tubular shape and has a lower end portion that contacts and separates from the valve seat 3 is inserted into the plunger insertion hole 2.

【0004】 ゲル切断プランジャ4の下部は小径となっており、下部と上部との間には受圧 面4bが形成され、ゲル切断プランジャ4の上部を押圧するばね(図示しない) により、ゲル切断プランジャ4は下方に付勢され、弁4aが弁座3に当接してい る。The lower part of the gel cutting plunger 4 has a small diameter, a pressure receiving surface 4 b is formed between the lower part and the upper part, and a spring (not shown) that presses the upper part of the gel cutting plunger 4 allows the gel cutting plunger 4 to be pressed. 4 is urged downward, and the valve 4a is in contact with the valve seat 3.

【0005】 プランジャ挿入孔2にはゲル流路5が連通し、ゲル流路5の端部は、ゲル圧縮 用プランジャ6が作動するシリンダ7に接続し、ゲル流路5の中間部はバルブ( 図示しない)を介してゲル貯留槽(図示しない)に連通し、ゲル貯留槽から補充 されたゲルGがゲル流路5内に充満している。A gel flow path 5 communicates with the plunger insertion hole 2, an end of the gel flow path 5 is connected to a cylinder 7 in which a gel compression plunger 6 operates, and an intermediate part of the gel flow path 5 is a valve ( The gel flow path 5 is connected to a gel storage tank (not shown) through the gel storage tank (not shown) and is replenished from the gel storage tank to fill the gel flow path 5.

【0006】 次に、ゲル圧縮用プランジャ6がプランジャ挿入孔2に向かって前進し、ゲル 流路5内のゲルGを昇圧すると、受圧面4bを押圧されたゲル切断プランジャ4 が上昇して開弁し、吐出されたゲルGがゲル膜G1 を形成し、次に、ゲル圧縮用 プランジャ6が後退すると、ゲル流路5内の圧力が低下してゲル切断プランジャ 4が下降して閉弁する(図5(ロ)参照)。Next, when the gel compression plunger 6 advances toward the plunger insertion hole 2 to pressurize the gel G in the gel channel 5, the gel cutting plunger 4 pressed against the pressure receiving surface 4b rises and opens. The discharged and discharged gel G forms a gel film G 1 , and when the gel compression plunger 6 retreats, the pressure in the gel flow path 5 decreases and the gel cutting plunger 4 descends to close the valve. (See FIG. 5B).

【0007】 閉弁すると、ゲル膜G1 が自重を支えきれなくなって落下するが、一部のゲル Gはプランジャ挿入口2の下方に残って新たなゲル膜G1 を形成し、自重により 垂れ下がる。 この新たなゲル膜G1 の形成から種子の被覆加工が開始され、種子供給装置( 図示しない)から落下供給される種子Sがゲル切断プランジャ4の内部を通過し て垂れ下がったゲル膜G1 の上に載置される(図5(ハ)参照)。When the valve is closed, the gel film G 1 cannot support its own weight and falls, but a part of the gel G remains below the plunger insertion port 2 to form a new gel film G 1 and hangs down due to its own weight. . The seed coating process is started from the formation of this new gel film G 1 , and the seed S dropped and supplied from the seed supplying device (not shown) passes through the inside of the gel cutting plunger 4 and hangs down of the gel film G 1 . It is placed on top (see FIG. 5C).

【0008】 次に、ゲル圧縮用プランジャ6が前進すると、ゲル流路5が昇圧し、受圧面4 bを押圧されたゲル切断プランジャ4が上昇して開弁し、吐出したゲルGが種子 Sを被覆する(図5(ニ)参照)。 所定時間後にゲル圧縮用プランジャ6が後退して閉弁し、種子Sを包み込んだ ゲル膜G1 が自重を支えきれなくなって落下する(図5(ホ)参照)。Next, when the gel compression plunger 6 advances, the pressure of the gel flow path 5 rises, the gel cutting plunger 4 pressed against the pressure receiving surface 4 b rises and opens, and the discharged gel G becomes seed S. (See FIG. 5D). After a predetermined time, the gel compression plunger 6 retracts and closes the valve, and the gel film G 1 enclosing the seed S cannot support its own weight and falls (see FIG. 5 (e)).

【0009】 一部のゲルGはプランジャ挿入口2の下方に残って新たなゲル膜G1 を形成し 、自重により垂れ下がる(図5(ヘ)参照)。 以上のようにして、ゲル膜G1 の形成、種子Sの落下及び種子Sのゲル被覆が 同期して連続的に行われ、次々と種子Sが被覆加工される。A part of the gel G remains below the plunger insertion opening 2 to form a new gel film G 1 and hangs down due to its own weight (see FIG. 5F). As described above, the formation of the gel film G 1 , the dropping of the seed S, and the gel coating of the seed S are continuously performed in synchronization with each other, and the seed S is coated one after another.

【0010】 落下する種子被覆ゲルは落下中に球状化されて下方の硬化剤槽に落下供給され て種子Sを被覆したゲル膜G1 の表面が硬化され、その後、水洗槽に送られて表 面に付着した硬化剤が除去される。The falling seed-coated gel is spheroidized during the falling and is dropped and supplied to the lower curing agent tank to cure the surface of the gel film G 1 coated with the seed S, and then sent to the washing tank to be exposed. The hardener attached to the surface is removed.

【考案が解決しようとする課題】[Problems to be solved by the device]

以上のような種子被覆加工は、連続的に且つ自動的に効率よく行われる利点が あるが、開弁により流出するゲル吐出量にばらつきが生じるので、種子の発芽率 をさらに高めるために、ゲル吐出量を厳密に制御する必要があった。 本考案はかかる課題を解決することを目的としており、ゲル量を厳密に且つ 容易に制御できる種子の被覆加工装置のゲル吐出機構を提供するものである。 The seed coating process as described above has the advantage of being efficiently performed continuously and automatically, but since the amount of gel discharged flowing out varies depending on the valve opening, in order to further increase the germination rate of seeds, It was necessary to strictly control the discharge amount. The present invention is intended to solve such a problem, and provides a gel discharge mechanism of a seed coating processing apparatus capable of strictly and easily controlling the gel amount.

【0012】[0012]

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するために、本考案の種子被覆加工装置のゲル吐出機構は、シ リンダ本体内部に、該シリンダ本体を貫通し端部に弁座を形成するプランジャ挿 入孔と、該プランジャ挿入孔に連通するゲル流路とを設け、ゲルを所定圧力で圧 送するゲル圧送ポンプの吐出口を上記ゲル流路の端部に接続し、筒状に形成され 上記プランジャ挿入孔に挿入されるゲル切断プランジャの一端に上記弁座に接離 する弁を形成し、ソレノイド等の電動アクチュエータの可動部を上記ゲル切断プ ランジャの他端側に連結し、上記ゲル切断プランジャの上方に配設され、種子を 間欠的に供給する種子供給装置の種子供給時期と上記電動アクチュエータの駆動 時期とを制御し、上記ゲル切断プランジャの開弁時間を制御する制御部を設けた ことを特徴とするものである。 In order to achieve the above-mentioned object, the gel discharge mechanism of the seed coating processing apparatus of the present invention comprises a plunger insertion hole for penetrating the cylinder body and forming a valve seat at the end, inside the cylinder body, and the plunger insertion hole. A gel flow channel communicating with the hole is provided, and the discharge port of a gel pressure pump for pumping the gel at a predetermined pressure is connected to the end of the gel flow channel, and is formed into a tubular shape and inserted into the plunger insertion hole. A valve is formed at one end of the gel cutting plunger to come into contact with and separate from the valve seat, a movable part of an electric actuator such as a solenoid is connected to the other end of the gel cutting plunger, and is arranged above the gel cutting plunger. A control unit that controls a seed supply timing of a seed feeder that intermittently supplies seeds and a drive timing of the electric actuator, and controls a valve opening time of the gel cutting plunger. It is intended.

【0013】[0013]

【作用】[Action]

上記のように構成された種子被覆加工装置のゲル吐出機構は、ゲル圧送ポンプ がゲルを所定圧力でゲル流路内に圧送するので、ゲル流路内の圧力は常に一定に 保たれる。 制御部の指令により電動アクチュエータの可動部が動作すると、ゲル切断プラ ンジャが開弁してゲルが吐出し、ゲル切断プランジャの閉弁によってゲルが落下 し、残りのゲルがゲル膜が形成する。 In the gel discharge mechanism of the seed coating processing apparatus configured as described above, the gel pressure pump pumps the gel into the gel channel at a predetermined pressure, so that the pressure in the gel channel is always kept constant. When the movable part of the electric actuator operates in response to a command from the control unit, the gel cutting plunger is opened and the gel is ejected. When the gel cutting plunger is closed, the gel drops and the remaining gel forms a gel film.

【0014】 種子供給装置から落下供給された種子がゲル膜の上に載置され、再びゲル切断 プランジャが開弁して吐出したゲルが種子を被覆する。そして、ゲル切断プラン ジャの閉弁により種子を被覆したゲルが下方の硬化剤槽に落下するが、表面張力 により落下中に球状化される。The seed dropped and supplied from the seed supply device is placed on the gel film, the gel cutting plunger is opened again, and the discharged gel covers the seed. Then, by closing the valve of the gel cutting plunger, the seed-coated gel drops into the lower hardening agent tank, but due to surface tension, it is spheroidized during the drop.

【0015】 以上の動作が繰り返されて次々と種子の被覆加工が行われるが、制御部により ソレノイド等の電動アクチュエータの可動部の動作時間が一定に制御されるので 、ゲル切断プランジャの開弁している時間が一定になり、一定圧力を有するゲル が一定時間に吐出される量もほぼ一定になる。 従って、種子を被覆するゲルの肉圧のばらつきが極めて小さくなる。Although the seed coating process is performed one after another by repeating the above operation, since the operation time of the movable part of the electric actuator such as the solenoid is controlled to be constant by the control unit, the gel cutting plunger is opened. The time during which the gel stays constant becomes constant, and the amount of gel having a constant pressure that is discharged in a constant time also becomes almost constant. Therefore, the variation in the meat pressure of the gel that coats the seed becomes extremely small.

To do. The gel pressure pump 17 replenishes the gel in the gel flow path 15 and is adjusted to a constant discharge pressure according to the seed.

【0018】 シリンダ本体11の上面には、ゲル切断プランジャ14の両側に位置するガイ ド棒18が立設され、ゲル切断プランジャ14の上部の外周面には、ほぼT字形 の連結板19の中央に設けられた取り付け用孔20が嵌合し、取り付け用孔20 の両側に設けられた小孔21にはガイド棒18が遊嵌する。 ゲル切断プランジャ14の上部の外周面に環状溝22が周設され、環状溝22 には、案内板19の脱落を防止する止め輪23が嵌着される。Guide rods 18 located on both sides of the gel cutting plunger 14 are erected on the upper surface of the cylinder body 11, and the center of a substantially T-shaped connecting plate 19 is provided on the outer peripheral surface of the upper portion of the gel cutting plunger 14. The fitting holes 20 provided in the fitting holes 20 are fitted, and the guide rods 18 are loosely fitted in the small holes 21 provided on both sides of the fitting holes 20. An annular groove 22 is provided around the outer peripheral surface of the upper portion of the gel cutting plunger 14, and a retaining ring 23 that prevents the guide plate 19 from falling off is fitted in the annular groove 22.

【0019】 両ガイド棒18の上端面にねじ孔が螺設され、押さえ板24に設けられた2個 の孔にそれぞれ挿入されるねじ25がねじ孔に螺合し、押さえ板24がガイド棒 18の上端面に取り付けられる(図2参照)。Screw holes are screwed into the upper end surfaces of both guide rods 18, screws 25 respectively inserted into two holes provided in the holding plate 24 are screwed into the screw holes, and the holding plate 24 is guided by the guide rods. It is attached to the upper end surface of 18 (see FIG. 2).

【0020】 コの字形状に屈曲成形されたソレノイド固定枠26の両端部が、シリンダ本体 11の両側面にねじ27により固着され、ソレノイド固定枠26の内面にソレノ イド28がねじ29により固着される(図3参照)。 ソレノイド28は、シーケンスコントローラより成る制御部(図示しない)の 指令により一定のタイミングで一定時間の間プランジャ30が突出或いは後退す る。Both ends of a solenoid fixing frame 26 bent and formed in a U shape are fixed to both side surfaces of the cylinder body 11 with screws 27, and a solenoid 28 is fixed to the inner surface of the solenoid fixing frame 26 with screws 29. (See FIG. 3). With respect to the solenoid 28, the plunger 30 is projected or retracted at a fixed timing for a fixed time according to a command from a control unit (not shown) including a sequence controller.

【0021】 連結板19の中央部から突出する連結腕31の先端部31aが下方に屈曲し、 プランジャ30の先端面に設けられたスリットに挿入され(図4参照)、連結腕 31の先端部とプランジャ30の先端部がピン32により連結される(図2参照 )。 従って、プランジャ30が突出或いは後退すると、ゲル切断プランジャ14が プランジャ挿入孔12内を上昇或いは下降する。The tip end portion 31 a of the connecting arm 31 protruding from the central portion of the connecting plate 19 is bent downward and inserted into a slit provided on the tip end surface of the plunger 30 (see FIG. 4). And the tip of the plunger 30 are connected by a pin 32 (see FIG. 2). Therefore, when the plunger 30 projects or retracts, the gel cutting plunger 14 moves up or down in the plunger insertion hole 12.

【0022】 以上のように構成された種子被覆加工装置のゲル吐出機構の作用を説明する。 ゲル圧送ポンプ17の吐出圧力は、種子に応じて一定の圧力に調整されるので 、ゲル流路15内のゲルGの圧力も一定に保持される。The operation of the gel discharging mechanism of the seed coating processing apparatus configured as described above will be described. Since the discharge pressure of the gel pressure pump 17 is adjusted to a constant pressure according to the seed, the pressure of the gel G in the gel channel 15 is also maintained constant.

【0023】 制御部の指令によりソレノイド28のプランジャ30が突出すると、ゲル切断 プランジャ14が上昇して開弁し、ゲルが吐出され、プランジャ30が後退する とゲル切断プランジャ下降して閉弁し、切断されたゲルが自重により落下し、残 りのゲルがゲル膜が形成する。このゲル膜の形成から種子被覆加工が開始する。When the plunger 30 of the solenoid 28 projects according to a command from the control unit, the gel cutting plunger 14 rises to open the valve, and the gel is discharged. When the plunger 30 retracts, the gel cutting plunger descends to close the valve. The cut gel falls by its own weight, and the remaining gel forms a gel film. The seed coating process starts from the formation of this gel film.

【0024】 制御部の指令により、種子供給装置から落下供給された種子がゲル膜の上に載 置され、再びプランジャ30が突出してゲル切断プランジャ14が一定の時間だ け開弁し、ゲルが一定の量だけ吐出されて種子を被覆する。そして、ゲル切断プ ランジャ14の閉弁により種子を被覆したゲルが下方の硬化剤槽に落下する途中 で球状化される。In response to a command from the control unit, the seed dropped and supplied from the seed supply device is placed on the gel film, the plunger 30 projects again, and the gel cutting plunger 14 opens for a certain period of time, so that the gel is released. A fixed amount is discharged to cover the seeds. Then, by closing the valve of the gel cutting plunger 14, the seed-coated gel is spheroidized while falling into the lower hardening agent tank.

【0025】 以上の動作が繰り返し行われて次々と種子の被覆加工が行われるが、制御部に の指令により開弁時間が一定に制御されるので、一定圧力を有するゲルの吐出量 もほぼ一定に制限される。従って、種子を被覆するゲルの肉圧のばらつきが極め て小さくなる。 又、ゲル流路15内の圧力を調整し、開弁時間を調整することにより、種子を 被覆するゲルの量を各種の種子に応じた適正量に調整することができる。Although the above operation is repeated to cover seeds one after another, since the valve opening time is controlled to be constant by a command to the control unit, the discharge amount of gel having a constant pressure is also substantially constant. Limited to. Therefore, the variation in the meat pressure of the gel that coats the seeds is extremely small. Further, by adjusting the pressure in the gel flow path 15 and adjusting the valve opening time, the amount of gel coating the seeds can be adjusted to an appropriate amount according to various seeds.

【考案の効果】[Effect of the device]

本考案は以上のように構成されているので、種子を被覆するゲルの量をほぼ一 定量にデッドボルト制御することが可能になり、種子の発芽率を向上させること が出来た。 又、ゲル流路内の圧力の調整,開弁時間の調整により、ゲルの吐出量を各種子 に適した量に微調整することができる。 Since the present invention is configured as described above, it becomes possible to control the amount of the gel covering the seeds by deadbolt almost uniformly, and it is possible to improve the germination rate of the seeds. Further, by adjusting the pressure in the gel flow path and adjusting the valve opening time, the amount of gel discharged can be finely adjusted to an amount suitable for each type of element.
