本発明は、移植機の技術に関する。 The present invention relates to a transplanter technology.
苗トレイの鉢部からセル成形苗を取出して植付装置によって畝上に移植する移植機は公知となっている。
前記移植機は、苗トレイからセル成形苗を取出す苗取出爪と、前記取出したセル成形苗を押出して植付装置に供給する苗押出具と、を備える（特許文献１参照）。
苗押出具は、前記取出したセル成形苗を植付装置に供給するときにセル成形苗の土部表面に当接する苗押出体を備える。苗押出具の苗押出体は、苗取出爪が貫挿されて苗取出爪のセル成形苗の取出し動作を案内する案内部を備える。
A transplanting machine that takes out a cell-molded seedling from a pot portion of a seedling tray and transplants the seedling on a cocoon by a planting device is known.
The transplanter includes a seedling extraction claw for extracting a cell-molded seedling from a seedling tray, and a seedling pusher that extrudes the extracted cell-shaped seedling and supplies the seedling to a planting apparatus (see Patent Document 1).
The seedling pushing tool includes a seedling extruding body that comes into contact with the soil surface of the cell-molded seedling when the extracted cell-molded seedling is supplied to the planting device. The seedling extrudate of the seedling extruding tool includes a guide unit that guides a cell molding seedling extraction operation of the seedling extraction claw through which the seedling extraction claw is inserted.
しかしながら、前記移植機では、セル成形苗を苗トレイから確実に取出すために、苗取出爪が板状等にして太くまたは大きく構成されるものがある。
このように苗取出爪を板状等にして太く等に構成すると、苗トレイからセル成形苗を取出し易くなるが、苗トレイからセル成形苗を取出すときに苗取出爪がセル成形苗（セル成形苗の葉部または茎部等）に接触し易くなり、セル成形苗が損傷してしまう場合がある。
また、苗取出爪を針状（細く）に構成すると、苗押出体の案内部が小さく構成され、苗取出爪によって取出されたセル成形苗を押出すときにセル成形苗の土部表面に当接する部分（苗押出体）が小さくなり苗取出爪によって取出されたセル成形苗を押出し難くなる。このため、苗取出爪によって取出されたセル成形苗を苗押出体によって押出せず、植付装置に供給することができない場合がある。

Consists of protruding. The seedling extrudate 56 is configured to have a portion protruding from the guide portion 57 at least in the front or rear. The seedling extrudate 56 contacts the soil surface 70b of the cell-molded seedling from the vicinity of the front end portion to the vicinity of the rear end portion of the cell-molded seedling soil surface 70b. The seedling extrudate 56 is configured in a divergent shape (substantially mountain-shaped) with the guide portion 57 as an apex at the front outer side and the rear outer side.
Guide part 57 of seedling extrudate 56 is inserted into seedling extraction claw 51 and guides the cell-molded seedling extraction operation (movement of seedling extraction claw 51 to the front end side or the base end side) in seedling extraction claw 51. . The front projecting portion 58 of the seedling extrudate 56 is configured by a portion projecting forward from the guide portion 57. The rear projecting portion 59 of the seedling extrudate 56 is configured by a portion projecting rearward from the guide portion 57.
以上のように、苗取出爪５１が針状に構成され、苗押出具５２の苗押出体５６が案内部５７から突出する部分（前突出部５８または後突出部５９）を有して構成される、移植機１では、苗取出爪５１が針状に構成されることから苗トレイ７０からセル成形苗を取出すときに、苗取出爪５１を板状等にして（太く等に）構成されるものに比べてセル成形苗（セル成形苗の葉部または茎部）に接触し難くなり、また、苗押出具５２の苗押出体５６が案内部５７から突出する部分を有して構成されることから案内部５７が小さく構成されても苗押出体５６（セル成形苗を押出すときにセル成形苗の土部表面７０ｂに当接する部分）を比較的大きく構成することができる。
したがって、移植機１によれば、苗取出装置５０の苗取出爪５１によって苗トレイ７０の鉢部７０ａからセル成形苗を取出すときにセル成形苗が損傷することを防止することができる。また移植機１によれば、苗取出装置５０の苗取出爪５１によって取出されたセル成形苗を苗押出具５２の苗押出体５６によって確実に押出して植付装置６０に供給することができる。
As described above, the seedling extraction claw 51 is configured in a needle shape, and the seedling extruding body 56 of the seedling extruding tool 52 is configured to have a portion (a front projecting portion 58 or a rear projecting portion 59) projecting from the guide portion 57. In the transplanter 1, since the seedling extraction claw 51 is configured in a needle shape, when the cell-molded seedling is extracted from the seedling tray 70, the seedling extraction claw 51 is configured in a plate shape (such as thick). Compared to those, it is difficult to contact the cell-molded seedling (the leaf portion or stem portion of the cell-molded seedling), and the seedling extruding body 56 of the seedling extruding tool 52 has a portion protruding from the guide portion 57. Therefore, even if the guide portion 57 is configured to be small, the seedling extrudate 56 (the portion that abuts the soil surface 70b of the cell-molded seedling when the cell-molded seedling is extruded) can be configured to be relatively large.
Therefore, according to the transplanter 1, it is possible to prevent the cell molded seedling from being damaged when the cell molded seedling is extracted from the pot portion 70a of the seedling tray 70 by the seedling extraction claw 51 of the seedling extraction device 50. Further, according to the transplanter 1, the cell-molded seedling taken out by the seedling picking claw 51 of the seedling picking device 50 can be reliably pushed out by the seedling pusher 56 of the seedling pushing tool 52 and supplied to the planting device 60.
苗取出装置５０は、苗トレイ７０の鉢部７０ａのセル成形苗を取出すときに、苗取出爪５１と苗押出具５２（苗取出爪５１の先端部と苗押出具５２の苗押出体５６と）を近接させた状態で、苗取出爪５１および苗押出具５２を、後方に移動させて苗トレイ７０の鉢部７０ａの上方に位置させる。苗取出装置５０は、苗トレイ７０の鉢部７０ａのセル成形苗を取出すときに、苗取出爪５１を先端側に移動させずに、苗取出爪５１および苗押出具５２を後方に移動させる。
そして、苗取出装置５０は、苗取出爪５１の先端部と苗押出具５２の苗押出体５６とを、苗トレイ７０の鉢部７０ａのセル成形苗の葉部または茎部の側方から苗トレイ７０の鉢部７０ａのセル成形苗の株元近傍（セル成形苗の葉部よりも土部表面７０ｂ側）に位置させる。このような状態において、苗取出装置５０は、苗トレイ７０の鉢部７０ａのセル成形苗側に苗取出爪５１を移動させて苗トレイ７０の鉢部７０ａからセル成形苗を取り出す。
When the seedling extraction device 50 takes out the cell-molded seedling of the pot portion 70a of the seedling tray 70, the seedling extraction claw 51 and the seedling extrusion tool 52 (the tip of the seedling extraction claw 51 and the seedling extrusion body 56 of the seedling extrusion tool 52) ) Are moved close to each other, the seedling picking claw 51 and the seedling pushing tool 52 are moved rearward and positioned above the pot portion 70 a of the seedling tray 70. The seedling extraction device 50 moves the seedling extraction claw 51 and the seedling extruding tool 52 backward without moving the seedling extraction claw 51 to the distal end side when taking out the cell-molded seedling of the pot portion 70a of the seedling tray 70.
The seedling extraction device 50 then connects the tip of the seedling extraction claw 51 and the seedling extruding body 56 of the seedling extruding tool 52 from the side of the leaf or stem of the cell-shaped seedling of the pot portion 70a of the seedling tray 70. The cell portion of the pot portion 70a of the tray 70 is positioned in the vicinity of the cell stock seedling stock (the soil surface 70b side of the leaf portion of the cell molded seedling). In such a state, the seedling extraction device 50 moves the seedling extraction claw 51 to the cell molding seedling side of the pot portion 70 a of the seedling tray 70 and takes out the cell molded seedling from the pot portion 70 a of the seedling tray 70.
以上のように、苗取出装置５０が、苗トレイ７０の鉢部７０ａからセル成形苗を取出すときに、苗取出爪５１の先端部と苗押出具５２の苗押出体５６とを、苗トレイ７０の鉢部７０ａのセル成形苗の葉部または茎部の側方から苗トレイ７０の鉢部７０ａのセル成形苗の株元近傍に位置させる、移植機１によれば、苗トレイ７０の鉢部７０ａのセル成形苗を取出すときに、セル成形苗の葉部または茎部に苗取出爪５１の先端部または苗押出具５２の苗押出体５６が接触することを防止することができる。
したがって、移植機１によれば、苗取出装置５０の苗取出爪５１によって苗トレイ７０の鉢部７０ａからセル成形苗を取出すときにセル成形苗が損傷することを防止することができる。
As described above, when the seedling extraction device 50 takes out the cell-molded seedling from the pot portion 70 a of the seedling tray 70, the tip of the seedling extraction claw 51 and the seedling extrusion body 56 of the seedling extrusion tool 52 are connected to the seedling tray 70. According to the transplanter 1, the pot portion of the seedling tray 70 is positioned in the vicinity of the cell-shaped seedling stock of the potted portion 70a of the seedling tray 70 from the side of the leaf or stem portion of the cell-shaped seedling of the potted portion 70a. When the cell molded seedling 70a is taken out, it is possible to prevent the tip portion of the seedling extraction claw 51 or the seedling extrudate 56 of the seedling pusher 52 from coming into contact with the leaf portion or stem portion of the cell molded seedling.
Therefore, according to the transplanter 1, it is possible to prevent the cell molded seedling from being damaged when the cell molded seedling is extracted from the pot portion 70a of the seedling tray 70 by the seedling extraction claw 51 of the seedling extraction device 50.

The seedling pusher 52 is configured to extend a single bar-like member downward from the mounting portion 54 (slightly rearward, upper, rear, and lower) to form a seedling pusher arm 55, with a single bar-like shape at the lower end. The seedling extrudate 56 is formed by bending the member. The seedling extrudate 56 is formed by bending a single bar-shaped member rearward and slightly inward at the lower end of the seedling extruding arm 55 to form the front protrusion 58, and then bending rearward and slightly outward to form the rear protrusion 59. The guide portion 57 is formed by bending forward and bending it in an annular shape between the front protrusion 58 and the rear protrusion 59.
以上のように、苗取出装置５０の苗押出具５２（苗押出アーム５５と苗押出体５６と）が棒状の部材で構成される、移植機１では、苗押出具５２が棒状の部材であることから、苗押出具５２の外面をエッジが比較的少ない構成とすることができる。
したがって、移植機１によれば、苗取出装置５０の苗取出爪５１によって苗トレイ７０の鉢部７０ａからセル成形苗を取出すときにセル成形苗が損傷することを防止することができる。
