【発明が解決しようとする課題】
この種、種子ホッパ内に下側より種子台を突入させてこの上端に種子を吸着させて取出すようにした播種装置にあっては、種子台の上下動により発生する衝撃が播種シャッタに伝わるため、シャッタ上の種子に乱れを生じさせてこの整列播種での整列精度を低下させるなどの不都合があった。

【0006】
前記種子台(5)上端には、ネジ部(18)を介し種子吸着ノズル(19)を取外し自在に固着させるもので、該ノズル(19)の上端円錐面中央の平坦部(19a)には前記流通孔(13)に連通させる小径(約0.3〜1.5mm)の種子吸着用のノズル孔(20)を開設する一方、前記流通孔(13)下部をホース(21)などを介し真空ポンプなど吸引機やコンプレッサー或いは送風機に連通接続させて、前記シリンダ(16)により種子台(5)の一定高さ上昇時に各ノズル(19)のノズル孔(20)に真空力で各一粒毎の種子を吸着して上昇させるように構成している。またノズル孔(20)の孔径及び平坦部(19a)の面積の異なるノズル(19)との取替えを容易とさせて、種子(A)の品種や形状に対応させたノズル孔(20)及び平坦部(19a)を有するノズル(19)を用いて、該ノズル(19)の一粒吸着精度を向上させるように構成している。
【0007】
そして、種子台(5)の一定高さ上昇時においては、ノズル孔(20)の真空吸引による吸着を停止させると共に、ノズル孔(20)から空気を加圧噴射させて、種子(A)をこの上方に臨ませる搬送パイプ(6)の送り始端部内に送り込んで播種位置まで気流搬送するように構成している。
【0008】
図3、図8に示す如く、前記播種ガイド(7)は搬送パイプ(6)の出口側に一体接続する放出ガイド(22)の出口下方に、内側の種子投入穴(23)を臨ませ、該投入穴(23)の下側をシャッタ開閉シリンダ(24)によりシャッタ(8)で閉塞するとき、搬送パイプ(6)からの種子(A)を投入穴(23)内でシャッタ(8)上に滞留させ、シャッタ開閉シリンダ(24)によってシャッタ(8)を開とさせるとき、投入穴(23)内で種子(A)の姿勢を整えてトレイ(1)内に落下させ、前記鎮圧具(9)の昇降シリンダ(25)の下降動作時に鎮圧具(9)によって形成される播種溝(C)上に種子(A)の播種を行うように構成している。
【0009】
前記種子ホッパ(4)及び播種シャッタ(8)とをそれぞれ別個に播種装置(3)の枠フレームを構成する支柱(26)に支持させるもので、前記支柱(26)にホッパ及びシャッタ取付剛体(27)(28)をそれぞれボルト(29)を介し取外し自在に固定させると共に、ホッパ取付剛体(27)の上面に防振ゴム或いはバネなど防振部材(30)を介し前記ホッパ台(15)を、またシャッタ取付剛体(28)の上面にベース(31)を介し前記シャッタ(8)及び開閉シリンダ(24)の取付枠(32)を固定させ、前記シャッタ(8)及び開閉シリンダ(24)の取付フレーム(33)を上下調節ネジ軸(34)及びスライドガイド軸(35)を介し取付枠(32)に取付高さ調節自在に連結させるように構成している。
【0010】
そして、前記昇降シリンダ(16)で種子台(5)を上下動させるときにホッパ(4)及びホッパ台(15)に発生する振動や衝撃がシャッタ(8)に伝わるのを、防振部材(30)及び取付剛体(27)(28)によって最小に防止して、種子台(5)の上下動作とシャッタ(8)の開閉動作がラップしても、シャッタ(8)上の種子(A)には振動や衝撃で種子姿勢に乱れを生じさせることのない整列精度良好の播種を可能とさせて、ホッパ(4)から種子(A)を取出してシャッタ(8)の開動作で播種を行うまでのサイクルタイムを短縮化して作業能率を向上させるように構成している。
【0011】
図9に示す如く、前記種子台(5)の上昇速度を調整する上昇制御弁(流量制御弁)(36)と、種子台(5)を上昇及び下降制御する上昇及び下降切換弁(37)とをコンプレッサー(38)と前記昇降シリンダ(16)の空圧回路間に介設すると共に、前記種子台(5)の空気流通孔(13)に送り込む空気圧及び真空圧の切換えを行う空気及び真空圧切換弁(39)と、空気圧及び真空圧のそれぞれの調整を行う空気圧及び真空圧調整弁(40)(41)とを前記種子台(5)とコンプレッサー(38)及び真空ポンプ(42)との接続回路間に介設して、種子ホッパ(4)内から種子台(5)を介し搬送パイプ(6)に種子1粒の取出しを行うように構成している。
【0012】
そして図10に示す如く、播種作業の自動を開始する自動スイッチ(43)と、種子台(5)の上昇速度を設定する前記上昇制御弁(36)の種子台上昇速度設定器(44)と、前記種子台(5)のノズル(19)の空気吸込圧及び空気吹出圧を調整する前記調整弁(41)(40)の空気吸込圧及び噴射圧設定器(45)(46)とをコントローラ(47)に接続させると共に、前記種子台上昇制御弁(36)及び上昇及び下降切換弁(37)と、空気及び真空圧切換弁(39)と、空気圧及び真空圧調整弁(40)(41)とにコントローラ(47)を接続させて、前記種子ホッパ(4)内の種子(A)の1粒をノズル(19)で取出してから播種位置まで搬送して播種するまでの一連の作業を自動で行うように構成している。
【0013】
而して図11、図12に示す如く、自動スイッチ(43)のオン操作によって種子(A)の自動整列播種作業を行うに際しては、前記各設定器(44)〜(46)によって、種子台(5)の上昇速度、種子台(5)の空気吸込圧及び吹出圧のそれぞれの設定を行うと共に、設定後で前記ノズル(19)上端面がホッパ(4)底部と略一致する種子台(5)の最下位置(図12の1)のとき、ホッパ(4)内の上下略中間高さ位置まで種子台(5)を上昇(図12の2)させた後、最下位置まで種子台(5)を下降(図12の3)させ、さらに種子台(5)をホッパ(4)内の上下略中間高さ位置まで上昇(図12の4)させた後、再度最下位置まで下降(図12の5)させ、この下降時に一粒の種子(A)をノズル(19)のノズル孔(20)に吸着させ、その後種子台(5)を最上位置まで上昇(図12の6)させて、ノズル(19)上端に吸着させる一粒の種子(A)を前記搬送パイプ(6)の下端部に近接させる(上昇及び下降の反覆回数は2回以上任意で良い)。このように種子台(5)を最下位置から最上位置まで上昇させる間に下降及び上昇の一定量の昇降動作を繰り返すことによって、ホッパ(4)内の種子(A)が掻き回されて、種子(A)の流動性が良好となって前記ノズル(19)に対する種子(A)一粒の吸着精度を向上させることができるものである。
【0014】
そして、種子台(5)が最上位置に上昇したときには前記切換弁(39)によって真空吸着が停止されると共に、ノズル孔(20)からは加圧空気が噴射されて、ノズル(19)上端の種子(A)を空気圧で搬送パイプ(6)内に送り込んで、播種位置まで搬送するものである。
【0015】
このように該実施例の場合、播種台(5)における真空吸引力及び加圧噴射力のみで、種子(A)の取出し及び搬送を可能とさせることができ、搬送パイプ(6)側からの吸込力などを必要とさせないので、部品点数や配管工数を削減させてコスト低減を図りメンテナンス性を向上させることができると共に、ノズル孔(20)からの空気の加圧噴射によってノズル孔(20)の塵詰まりなども低減させることができる。なお前述実施例にあってはノズル孔(20)に種子(A)を吸着させるのに、真空ポンプ(42)の真空圧を用いる構成を示したが、コンプレッサ(38)のみを用いてエゼクタ作用などによってノズル孔(20)に種子(A)を吸着させる構成でも良い。
【0016】
【発明の効果】
以上実施例から明らかなように本発明は、種子ホッパ(4)内に下側から種子台(5)を突入させてこの上端のノズル孔(20)に種子(A)を吸着させて取出すと共に、前記ノズル孔(20)よりの加圧噴射空気でもって種子(A)を搬送部材(6)内を流通させて播種シャッタ(8)まで搬送して、該シャッタ(8)の開動作によって播種を行うようにした播種装置において、種子ホッパ(4)と播種シャッタ(8)とをそれぞれ別個に装置本体に支持させるホッパ取付剛体(27)及びシャッタ取付剛体(28)を設けると共に、ホッパ取付剛体(27)に防振部材(30)を介し種子ホッパ(4)を取付けるものであるから、ホッパ(4)内を上下動するときに発生する種子台(5)の振動や衝撃が、播種シャッタ(8)に伝わるのを防振部材(30)によって良好に防止して、種子台(5)の上下動作と播種シャッタ(8)の開閉動作がラップしても、整列精度に悪影響を与えることなくこのサイクルタイムを短縮させて作業能率を向上させることができると共に、防振部材(30)の支持で発生するホッパ(4)自体の振動によってホッパ(4)内の種子(A)のブリッジなども解消されて常に良好な播種作業を可能とさせることができるものである。

As described above, in the case of the embodiment, the seed (A) can be taken out and transported only by the vacuum suction force and the pressure injection force in the seeding table (5), and can be removed from the transport pipe (6) side. Since no suction force is required, the number of parts and the number of pipes can be reduced, the cost can be reduced and the maintainability can be improved, and the nozzle hole (20) can be improved by pressurized injection of air from the nozzle hole (20). Dust clogging can be reduced. In the above-described embodiment, the configuration in which the vacuum pressure of the vacuum pump (42) is used to adsorb the seed (A) in the nozzle hole (20) is shown. However, the ejector action is performed using only the compressor (38). The structure which makes a nozzle hole (20) adsorb | suck a seed (A) by etc. may be sufficient.

【The invention's effect】
As is apparent from the above embodiments, the present invention allows the seed stand (5) to enter the seed hopper (4) from the lower side, and the seed (A) is adsorbed and taken out by the nozzle hole (20) at the upper end. The seed (A) is circulated through the conveying member (6) to the sowing shutter (8) with the pressurized jet air from the nozzle hole (20), and is seeded by opening the shutter (8). in sowing apparatus to perform, the hopper mounting rigid to support the seed hopper (4) seeding shutter (8) and to each separate device body (27) and provided with a shutter mounted rigid (28), said hopper mounting Since the seed hopper (4) is attached to the rigid body (27) via the vibration isolating member (30), the seed pedestal (5) vibration and impact generated when the hopper (4) is moved up and down is sown. It is transmitted to the shutter (8) This cycle time can be shortened without adversely affecting the alignment accuracy even if the vertical movement of the seed table (5) and the opening / closing operation of the seeding shutter (8) are overlapped. The work efficiency can be improved and the bridge of the seed (A) in the hopper (4) is eliminated by the vibration of the hopper (4) itself generated by the support of the vibration isolating member (30). It is possible to make the sowing work possible.
