る。[Detailed description of the invention] [Industrial field of application] The present invention is based on a seedling tray equipped with a vertical seedling feeder that vertically feeds pine-shaped seedlings toward the lower seedling take-out port. The present invention relates to a seedling planting device that is equipped with a seedling holding rod that can be switched between a holding position in which the seedlings are pressed toward a mounting surface and a holding release position in which the seedlings are floated.
この種の苗植付装置としては、一般に、苗押さ

ものが知られている。
This type of seedling planting device generally has one in which a seedling holding rod is swingably pivoted to the seedling take-out port side of a seedling stand, and a four-parallel link between the seedling holding stand and the seedling holding stick. It is known that the seedling stand is movable in parallel or substantially parallel to the seedling stand.

がある。
In the case of the conventional former method, when the seedling holding rod is switched to the holding release position, the seedling holding rod can be lifted up from the seedling resting table, making it easy to maintain the vertical seedling feeder, etc. However, if the thickness of the soil on which the seedlings are placed changes, the seedling holding rod, which has been switched to the holding position, will no longer be parallel to the seedling stand, and the seedling holding rod will not be able to hold the seedlings in the soil. There is a problem in that the parts are pressed locally.
また、後者による場合は、載置苗の床土部分の
厚み変化に拘らず、苗押さえ杆全体で載置苗の床

が行いにくくなる問題があつた。 In addition, in the case of the latter, although the whole seedling holding rod can press the soil part of the seedling bed almost evenly regardless of the change in the thickness of the soil part of the seedling bed, the seedling holding rod is released. There was a problem in that the floating distance from the seedling stand was small when changing the posture, making maintenance difficult.

理的な改造をもつて上述の二律背反的な問題点を
改善する点に目的を有する。 The purpose of the present invention is to improve the above-mentioned trade-off problem by rationally modifying the seedling holding allowance and the seedling holding rod.

The characteristic configuration of the seedling planting device according to the present invention, which was taken to achieve such an object, is that the seedling holding rod, which is in a holding position, is placed between the seedling placing stand and the seedling holding rod relative to the seedling placing stand. The device is provided with a multiple link mechanism that can levitate in parallel or almost parallel and then levitate and swing using its attachment base end as a fulcrum, and its functions and effects are as follows.
押さえ作用姿勢にある苗押さえ杆を、押さえ解

When switching the seedling holding rod that is in the holding position to the holding release position, the seedling holding rod is floated parallel to the seedling stand and then further floated and swung using its attachment base end as a fulcrum. When in the holding position, the entire seedling holding rod can press the bed soil part of the placed seedlings almost evenly, regardless of changes in the thickness of the bed soil part of the placed seedlings, and at the same time, it is in the holding release position. Sometimes, it is possible to secure a large space between the seedling stand and the seedling stand.

Therefore, as mentioned above, by switching the posture of the seedling holding rod by a combination of parallel movement and rocking movement, maintenance work is facilitated, and the soil part of the bed of the seedlings placed is always appropriately pressed. be able to. Moreover, since the movement of the seedling holding rod is performed via a multiple link mechanism, it may be difficult to move the seedling holding rod, for example, when the seedling holding rod is slid along the guide groove of a bracket connected to the seedling stand. The occurrence of such problems can be minimized, and the components can be operated reliably at all times while ensuring durability.

するバネ21h,21iを張設している。 This multiple link mechanism 21 is constructed by connecting pins 21a and 21 along the left and right direction to the brackets 22 erected on the left and right partition frames 6c of the seedling stand 6, respectively.
A pair of left and right first links 21c and a second link 21d are provided, each of which is swingable around the b-axis. A plurality of support rods 23 are installed in the seedling placement area, and a third support rod 23 fixed to the support rod 23 is installed.
The locking pin 21f of the link 21e is engaged with the elongated hole 21g formed on one end side of the first link 21c and the elongated hole 22a formed in the bracket 22, which is approximately inverted L-shaped in side view, and , between the other end of the first link 21c and the bracket 22, and between the second link 21d and the seedling stand 6 side, the seedling holding rod 20 is held down on the side in the working position,
In other words, springs 21h and 21i are tensioned to move and bias the seedling mounting surface 6b of the seedling mounting table 6.

とになる。 Then, when the free end of the second link 21d is pulled down against the elastic biasing forces of the springs 21h and 21i, the first link 21c swings to its maximum.
The seedling holding rod 20 floats and moves almost parallel to the seedling resting table 6, and from then on, the locking pin 21f moves to the first position.
Bracket 2 along long hole 21g of link 21c
Since the seedling holding rod 20 is moved into the locking portion of the inverted L-shaped long hole 22a of No. 2, the seedling holding rod 20 is accordingly swung to a retracted position in which the seedling holding rod 20 is largely raised from the seedling resting table 6.

ている。 This interlocking mechanism 24 has a rotatable support shaft 24c provided with first and second arms 24a, 24b whose orientations differ by approximately 90 degrees, mounted on a bracket 25 fixed to the back surface of the seedling stand 6. The first arm 24a and the arm 17 of the vertical feed drive mechanism B
are pivotally connected via a third arm 24e with an adjustment bolt 24d, and the second arm 24b
A pin 24g that can engage with a hook 24f pivotally connected to the second link 21d of the multiple link mechanism 21 is fixed to the tip of the vertical seedling feeder 13.
By pushing down the hook 24f in conjunction with the operation of vertically feeding the seedlings, the seedling presser rod 20, which is in the holding position, is switched to the holding release position against the elastic biasing force of the springs 21h and 21i. .
前記フツク24fの係止部は、前記ピン24g

できる利点がある。 Furthermore, the adjustment bolt 24d allows the arm 1 to
Since the contact timing with respect to the pin 17a fixed to the pin 7 can be freely adjusted, for example,
When the bed soil portion of the placed seedlings is thick, there is an advantage that by making the contact timing earlier, a delay in releasing the holding of the seedling holding rod 20 during vertical feeding of the seedlings can be prevented.
