本考案は、循環駆動される植付爪に保持された
苗を爪先端がわへ押出し分離するための苗押出具
と、前記植付爪に保持された苗をこの植付爪とで
挾持する補助苗支持具とを設け、前記補助苗支持
具を、前記植付爪側に近づく苗支持姿勢と、前記

構成してある苗植付装置に関する。[Detailed description of the invention] The present invention consists of a seedling pusher for pushing out and separating the seedlings held by the planting nails to the tip of the nails, which are driven in circulation; An auxiliary seedling support that is held between the planting nails is provided, and the auxiliary seedling support can be switched between a seedling support posture that approaches the planting nail side and a non-seedling support posture that moves away from the planting nail side. The present invention relates to a seedling planting device configured.

を非苗支持姿勢に切換える際に、植付泥面中での
補助苗支持具の作動によつて植付泥面がかき乱さ
れ、苗植付姿勢が乱れ易い欠点があつた。 The above-mentioned seedling planting device enables the seedlings to be supported by being sandwiched between the planting claws and the auxiliary seedling supporter in the seedling support position, so that the seedlings held by the planting claws can be supported. In addition, when the seedling is pushed out and separated from the planting nail by the seedling extrusion tool, the seedling extrusion tool prevents the seedling from separating from the planting nail unexpectedly. When planting seedlings, the seedlings and the seedling extruder may unexpectedly adhere to each other due to strong contact with the seedlings that have been inserted into the container, resulting in the seedlings being lifted up again. In order to avoid disturbing the planting position, the auxiliary seedling support device is configured to switch to a non-seedling support position when planting seedlings. It is difficult for the seedlings to enter smoothly and well between the seedling support tool in the supporting position, and as a result, there is a risk of inconveniences such as damaging the seedlings or causing mistakes in taking out the seedlings, and when planting the seedlings. When switching the auxiliary seedling support to a non-seedling supporting position, the operation of the auxiliary seedling support within the planting mud surface disturbs the planting mud surface, resulting in a problem in that the seedling planting position is easily disturbed.

せることができるように構成してある。 The seedling supporter 11 is constructed by fixing its base to the movable case 5, and using the base as a fulcrum in a seedling support position A and a non-seedling support position B in which it moves further away from the claws 6. It can be transformed into
In addition, it is constituted by a leaf spring that can be deformed to return to the non-seedling support position B. And the seedling support tool 11
is in the non-seedling support posture B during the seedling retrieval phase of the planting claw 6, then in the seedling support posture A while the planting claw 6 reaches the seedling planting phase, and in the non-seedling support posture in the seedling planting phase. In order to switch to the position B, a pressing part 12 is provided on the rod 7a of the seedling pusher 7, which presses the seedling supporter 11 into the seedling support posture A by moving the rod 7a.
The rotary cam 10 is provided with a cam surface S 1 for moving the pressing part 12 backward to a position where it does not contact the seedling support 11 during the seedling removal phase of the planting claw 6 and the planting claw 6 is in the seedling removal phase. A cam surface S 2 is provided for protruding and moving the pressing part 12 to a position where it comes into contact with the seedling support 11 immediately after passing through the seedling support 11 . A notch 13 is formed into which the pressing part 12 that protrudes and moves in the attaching phase can be inserted, and the seedling is prevented from entering between the planting claw 6 and the seedling support 11 when the planting claw 6 takes out the seedling. In addition, when the seedlings are pushed out and separated by the seedling pusher 7, the amount of return deformation of the seedling support 11 toward the planting claw 6 side is controlled by the seedling pusher 7.
The structure is such that the space between the planting claw 6 and the seedling support 11 can be wide open for the purpose of detaching the seedling, while being restricted by contact with the seedling.

ように構成してあることを特徴とする。 In summary, the present invention, in the above-mentioned seedling planting device, urges the auxiliary seedling support 11 to return to the non-seedling support posture B and attaches it to the planting claw 6 side, and The support tool 11 is placed in a non-seedling support position B during the seedling removal phase of the planting claw 6,
Thereafter, a switching operation mechanism is provided for switching the planting claw 6 to the seedling support posture A against the urging force while the seedling planting phase is reached, and to the non-seedling support posture B during the seedling planting phase. It is characterized in that the range of return movement of the auxiliary seedling supporter 11 to the non-seedling support posture B during the seedling planting phase is regulated by contact with the seedling pusher 7.
即ち、苗支持具１１を、植付爪６の苗取出し位

１１との間を苗侵入のため大きく開放させること
ができるようにしてあるから、植付爪６による苗
取出しに際して、苗が植付爪６と苗支持具１１と
の間に円滑、良好に侵入できる。 That is, by making it possible to switch the seedling support 11 to a non-seedling support posture B in which the seedling support posture B is moved in a direction away from the planting nails 6 from the seedling support posture A during the seedling removal phase of the planting nails 6, Since the gap between the planting claw 6 and the seedling support 11 can be left wide open for seedling intrusion, when the seedling is taken out by the planting claw 6, the seedling does not come between the planting claw 6 and the seedling support 11. It is possible to penetrate smoothly and well between the two.
そして、苗を取出した後苗植付位相に至る間に
おいて、苗支持姿勢Ａに切換えるので、苗取出し
時において苗が植付爪６と苗支持具１１との間に
円滑、良好に侵入できるにもかかわらず、苗を強
力に支持し、苗支持姿勢が乱れにくい。 Then, after taking out the seedlings and before reaching the seedling planting phase, the position is changed to the seedling supporting posture A, so that the seedlings can smoothly and well enter between the planting claw 6 and the seedling support 11 when taking out the seedlings. Despite this, it strongly supports the seedlings and does not easily disturb the seedling support posture.

能となつた。 Furthermore, by configuring the seedling support 11 to be able to switch to the non-seedling support posture B during the seedling planting phase of the planting claw 6, the distance between the planting claw 6 and the seedling support 11 can be reduced. Since the can be opened wide for seedling separation, when pushing out and separating the seedlings with the seedling pushing tool 7, the seedlings can not only be separated smoothly and reliably, but also the seedlings can be pushed out and separated by the seedling pushing tool 7. When doing so, the movement range of the seedling support 11 returning to the non-seedling support posture B is regulated by contact with the seedling pushing tool 7, and the movement of the seedling support 11 on the planting mud surface is suppressed as much as possible. Although the seedlings are separated smoothly and reliably, the planting mud surface is not easily disturbed by the seedling support 11, and the seedling support posture relative to the planting claws 6 is not easily disturbed. This has the effect that the planting posture of the seedlings is less likely to be disturbed immediately after planting, thereby simultaneously solving both of the above-mentioned problems and making it possible to carry out even better seedling planting work.
