Abstract

PURPOSE:To surely separate and transplant a pot seedling by opening a dividing port closing unit capable of opening and closing a seedling dividing port in pressing and nipping the outside on the lower part side of the pot seedling with transplanting pawls and lowering the transplanting pawls. CONSTITUTION:Each of pot seedlings (A) delivered onto a closing unit 46 is grasped by transplanting pawls 84 and the outside on the lower part side of the pot seedling is pressed and nipped thereby near a connecting part of the pots. When the transplanting pawls are lowered after nipping the pot seedling, a dividing port 43 is opened by the closing unit 46 with pressing force thereof against a spring to separate the seedling (A). When the pot seedling is nipped by the transplanting pawls, the internal nursery bed will not be crumbled down.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a transplanting device for transplanting vegetables, flowers, etc.

Conventional technology Conventionally, seedlings are grown in paper seedling pots in which the opening edges of each seedling pot are connected to each other, and the potted seedlings are placed upside down on a seedling stand, and the pots are placed one by one from the seedling dividing opening. A structure in which a seedling is separated by being sandwiched between a pair of left and right transplant claws and then transplanted is known as seen in Japanese Patent Application Laid-open No. 56210/1983.

However, in this prior art, the dividing port is simply open and does not have a structure to open and close.

Problems to be Solved by the Invention In the conventional system, when potted seedlings are fed out into the seedling splitting opening, the seedlings are raised in the pot upside down, so that the seedlings are raised inside the pot upside down. The seedbed (seedling nursery) fell directly from the lower part 11 through the dividing opening, and if the transplanted claws were used to pinch the pot from the outside and separate it, the pot would simply become dented and could not be held firmly. However, there was a drawback that the seedlings could not be separated in a predetermined position, making it impossible to reliably transplant them.

Technical means for solving the problems In order to solve the above problems, the present invention takes the following measures.

That is, the present invention provides a paper seedling raising pot A in which the seedling raising pots A are arranged in front, back, left and right so that the upper end opening circumferences of the pots A are provided with growth holes a at the bottom through which the stems of plants grow. One seedling A in each pot is sent out to the seedling separation port 43 of the seedling platform 42 on which the seedlings grown in the upside-down manner are placed, and the seedlings A are separated from the left and right sides using the transplanting claws 84 of the transplanting machine. In a transplanting device that divides the seedlings by pinching them, takes them out, and transplants them, the seedling separation opening 43 is provided with a division opening closing body 46 that can open and close the division opening 43, and this closing body 46 is connected to the transplantation claw 84.
The transplanting device is configured to open when descending after pinching and clamping the outside of the lower part of the potted seedling A.

Functions and Effects of the Invention According to the present invention, when a potted seedling is separated from a seedling dividing opening, the potted seedling is fed out onto the upper part of the separating opening closing body that closes this dividing opening, so that the seedling bed inside the pot is accidentally damaged. The separation opening closing body is only opened when the outside of the lower part of the potted seedling is held under pressure by the left and right transplanted claws without falling, and when it is pulled downwards and separated, the separation opening closing body is opened for the first time, so the clamped potted seedling can be separated. In addition to stabilizing the posture, when holding the potted seedlings with the transplanting claws, the internal seedling bed does not collapse, allowing reliable separation and transplantation.

At the time when this grasping is completed, the closing body 46 has not moved downward yet, and when the potted seedling is surely gripped by the transplant claws and descends, the closing body 46 is opened against the spring 51 by the pressing force. That is, the key point of the present invention is that the closing member 46 opens the dividing opening 43 after the transplanted claws have securely clamped the potted seedling.

Next, the operation of the above example will be explained.

First, to explain the seedlings to be transplanted using a transplanter, the paper first
As shown in Fig. 5, the pyramid-shaped seedling raising pots 101 with holes a in the bottom are integrally connected to each other at their upper edges, and the group of seedling pots 101 having independent bottoms has a rectangular shape when viewed from a plane as a whole. Seedlings are grown in the constructed ai'rJ device 100 as follows.

Lay the board 102 on the back of the FF1 helmet 100, fill it with the floor (b), and then from above! Cover with a Li box 103, turn it upside down, remove the board 102 that is on the top side, insert appropriate protrusions into each hole a, dig a hole, sow seeds of vegetables etc. in it,
Cover with soil (c), water, and germinate from hole a to pot seedling A.
raise.

The seedlings A grown in this way are mounted on the seedling stand 38,
Propulsion wheels 8a, 8b and rolling wheels 21a.

21b straddles the ridge B, the aircraft is propelled, and each part is made to rotate by transmission. Then, the grounding body 27 comes into contact with the upper surface of the ridge B and is propelled, and when the height of the ridge B changes, the valve 31 of the hydraulic system is switched to move the propulsion vehicles 4'Q8a, 8b and the rolling wheels 2La, 21b. is automatically raised and lowered, and the height of the aircraft body is always maintained within a certain range of heights from the top surface of the ridge B.

On the other hand, the first rotating case 55 and the second rotating case 56 are inverted with respect to each other, and the tip of the transplanting claw 84 of the transplanting tool 76 attached to the second rotating case 56 side forms a vertically elongated closed-shaped transplanting trajectory when viewed from the side. (D) and pass through the seedling dividing opening 43 of the seedling mounting stand 42.

Further, the potted seedlings A to be placed by reciprocating left and right movement of the seedling mounting table 38 are fed out one by one onto the upper surface of the closing body 46 of the seedling dividing opening 43, and the potted seedlings A are held by the transplanting claws 84. It is pulled downward and divided.

That is, when the fixed transplant claw 84a and the movable transplant claw 84b descend from the upper side of the potted seedling drawn out on the closure body 46 so as to sandwich both left and right sides of the potted seedling, and reach a position slightly above the lower end of the potted seedling A. The movable transplanted nail 84b is the fixed transplanted nail 8
4a side to firmly clamp the lower outside of the potted seedling A, and then descend to push down the closing body 46 through the potted seedling A to separate the seedling A. Therefore, at the time when the potted seedling A is held between the transplant claws 84, the bottom of the seedling A is attached to the closed body 4.
6, the bed soil inside the bot 101 does not fall downward and is securely clamped, and after clamping, the internal floor is compacted and the posture of the clamped seedlings is stabilized.

Then, as the transplanted claw 84 descends, the seedling dividing opening 43 is gradually opened, and the leaves of the seedling pass through the dividing opening 43. At this time, the seedling dividing opening 43 remains open, but the potted seedling A held by the transplanting claws 84 plunges into the ridge B, the movable transplanting claws 84b rotate outward, and the seedling pusher 87 moves to heel the clamped seedling and transplant it, and when it rises again, the operating protrusion 96 of the transplanting case 76a engages the operating arm 50 to raise the closing body 46, and the seedling dividing opening 43 Close.

In this way, the pot rW A is implanted in a predetermined and precise posture.
