Description

TECHNICAL FIELD The present invention relates to a transplanting device for transplanting vegetables, flowers and the like.

[Prior art]

As a conventional technique, in Japanese Patent Laid-Open No. 63-42612, the seedlings are sent one by one to the seedling separation port of a seedling receiving stand on which the seedlings whose side portions are covered by a seedling raising device and whose bottom portions are not covered are placed. ,
In a transplanting device that divides this from the left and right sides with the transplanting claw of the transplanter and takes out and transplants, a seedling separating port is provided with a split mouth closing body that can open and close the splitting mouth, and this closing body is opened and closed. An implanting device configured to open and close by a drive mechanism is disclosed.

[Problems to be solved by the invention]

In the above-mentioned conventional device, since the closing body is opened and closed by the closing body opening / closing drive mechanism, it is very difficult to match the timing at which the transplant nail passes through the dividing port. In some cases, the seedlings cannot be held or split in a certain posture, and reliable transplantation may not be possible, or the seedbed in the nursery may collapse from the bottom of the seedlings, making it difficult for the seedlings to attach to the field. there were.

[Technical means for solving problems]

The present invention has taken the following means in order to solve the above problems.

That is, the present invention sends out the seedlings A one by one to the seedling separation ports 43 of the seedling receiving table 42 on which the seedlings A whose side portions are covered and the bottom portions are not covered by the seedling raising device 100 are placed. In a transplanting device that divides this from the left and right sides by the transplanting claw 84 of the transplanter and takes out and transplants, the seedling separating port 43 is provided with a split mouth closing body 46 capable of opening and closing the dividing mouth 43, and this closing body
46 is a transplanting device configured to be opened when the transplanting nail 84 holds the seedling A and lowers it.

[Operation and effect of the invention]

According to this invention, when the seedling is separated from the seedling dividing port,
Since the seedlings are delivered to the upper part of the separation port closing body that closes the splitting port, the seedbed does not fall from the bottom of the seedlings that are not covered by the seedling raising device. Then, the transplanted nail holds the seedling and descends, but since the closing body opens due to the descending motion of the transplanted nail, the seedling of the transplanted nail is held in a stable and separated posture, and is covered with the seedling raising device. Since the bottom of the seedling is pressed against the separation opening closing body and hardened, it is held by the transplanting nails and descends, so the seedbed in the nursery does not collapse easily, the seedlings are reliably separated and transplanted, and the survival is also good. .

The point of the embodiment of the present invention in the above example is the relationship of the split mouth closing body 46 at the time of holding and taking out the pot seedling with the fixed transplant nail 84a and the movable transplant nail 84b from the seedling split mouth 43, and the transplant nail Starts to grab the pot seedlings fed out on the closing body 46 at a position of about 2 to 3 mm from the upper surface of the closing body, and completes the grasping at a position approaching the connecting portion of the pots. At the time of completion of this grasping, the closing body 46 does not move downward yet, and when the pot seedling is securely held by the transplanting claws and descends, the closing body 46 is opened against the spring 51 by the pressing force. That is, the point of the present invention is that the closing body 46 opens the dividing port 43 after the transplanted nail holds the pot seedling with certainty.

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

First, let's start with the seedlings that are transplanted with a transplanter.
As shown in FIG. 15, a polygonal pyramidal seedling pot 101 having a hole a at the bottom as shown in FIG. 15 is integrally connected to each other at its upper edge so that the bottom portion becomes independent. The seedlings 100 thus constructed are used to grow seedlings as follows.

A plate 102 is laid on the back surface of the seedling raising device 100, and the soil (b) is filled, and the seedling box 103 is put over the plate 102 to turn it upside down. The pot b is sown by digging a hole, sowing seed b such as vegetables, covering it with soil (c) and irrigating, and germinating from the hole a.

The seedling A thus raised is mounted on the seedling mount 38,
The propulsion wheels 8a, 8b and the rolling wheels 21a, 21b propel the machine body while straddling the ridge B, so that each part can be transmitted and rotated. Then
When the grounding body 27 is propelled against the upper surface of the ridge B and the height of the ridge B is changed, the valve 31 of the hydraulic system is switched to automatically move the propulsion wheels 8a, 8b and the rolling wheels 21a, 21b. By raising and lowering, the height of the machine body is always maintained within a certain range from the upper surface of the ridge B.

On the other hand, the first rotary case 55 and the second rotary case 56 are inverted from each other, and the tip of the transplanting claw 84 of the transplanter 76 attached to the side of the second rotary case 56 is vertically closed in a side view and is a closed locus. Draw (d) and pass through the seedling dividing opening 43 of the seedling stand 42.

Further, the pot seedlings A on which the seedling placing table 38 reciprocates left and right are placed one by one on the upper surface of the closing body 46 of the seedling dividing port 43, and the pot seedlings A are held by the transplanting claws 84. It is pulled down and divided.

That is, when the fixed transplanting claw 84a and the movable transplanting claw 84b descend from the upper side of the pot seedling A fed onto the closing body 46 so as to sandwich the left and right sides thereof, and reach a little above the lower end of the pot seedling A. The movable transplanting claw 84b operates toward the fixed transplanting claw 84a to firmly hold the lower outside of the pot seedling A, and the descending thereafter pushes down the closing body 46 via the pot seedling A, so that the seedling A
Is separated. Therefore, at the time when the transplanting claw 84 holds the pot seedling A, since the bottom of the seedling A is received by the closing body 46, the floor soil in the pot 101 does not fall downward, and is reliably held and held. After that, the soil inside is compacted and the posture of the sandwiched seedlings becomes stable.

Then, the seedling dividing port 43 is gradually opened as the transplanting nail 84 descends, and the leaf portion of the seedling passes through the dividing port 43. At this time, the seedling dividing port 43 maintains the open state, but the transplanting nail 84
When the pot seedling A held by the ram plunges into the ridge B and the movable transplanting claw 84b rotates outward, the seedling extruder 87 moves and the sandwiched seedling is separated and transplanted, and when it rises again. This time, the operating protrusion 96 of the transplant case 76a engages the operating arm 50 to raise the closing body 46, and closes the seedling dividing port 43.

In this way, the pot seedling A is transplanted in a predetermined and accurate posture.
