Description

[Detailed Description of the Invention] Industrial Application Field This invention is a method of partitioning the top surface of a strip-shaped bottom plate at regular intervals as shown in FIG. Raise potted seedlings in a nursery stand, load the potted seedlings together with the seedling stand onto the machine, push out the potted seedlings one by one from the nursery room of the seedling stand, and drop them to the ground for planting. The present invention relates to improvements in the constructed vegetable transplanting machine, and more particularly to a device for confirming the set position of a seedling stand in a vegetable transplanting machine for accurately setting the seedling stand to the machine body.

2. Description of the Related Art A conventional transplanting machine is explained with reference to FIG. 6. A machine body that can move freely by drive wheels 3 has a seedling stand 6 on which a large number of seedling stands can be loaded, and the seedling stand. The seedlings are pushed out by a frame 5 that supports the seedlings so as to be movable back and forth, a seedling stand transport device that sequentially transports the seedling stands to a seedling extrusion device provided on the seedling stand conveyance path 9, and an extrusion frame 10 of the seedling extrusion device. Planting device 1 for planting potted seedlings on the ground surface
1 and an empty box recovery device for storing empty seedling stands from which potted seedlings have been pushed out.

To use this transplanter, first place a large number of seedling stands in parallel on the seedling stand 6, adjust and move the seedling stand 6 back and forth, and place the last seedling stand on the seedling stand transport path 9. Stop facing the entrance. Then move the seedling stand to seedling transport path 9.
When pushed in, the seedling chamber at the tip of the seedling stand opposes and stops the extrusion rod 10 of the seedling extrusion device, and the feeding claw of the seedling stand conveying device is swingably latched onto the bottom of the seedling stand. .

When the machine is run, the extrusion rod 10 protrudes, and the potted seedlings in the tip seedling chamber are extruded. The extrusion rod 10 that has extruded the potted seedlings momentarily retreats to prepare for the next extrusion. On the other hand, the feeding claw of the seedling feeding device is
When the extrusion rod 10 retreats, it swings to position the next seedling chamber in front of the seedling extrusion rod 10. Then, the extrusion rod 10 that had been retreating protrudes and pushes out the potted seedlings from the seedling chamber and causes them to fall to the ground. In this manner, as the machine moves, the potted seedlings are pushed out from the third, fourth, etc. seedling chambers, and finally the entire seedling stand is sent into the seedling stand transport path 9. Then, the seedling stand 6 moves backward by one booth, and the next seedling stand is stopped facing the entrance of the seedling stand transport path 9. Then, the feed pawl of the seedling stand transport device swings to send the seedling stand into the seedling stand transport path 9 following the preceding first seedling stand.

As is clear from the above, in the conventional vegetable transplanting machine, when the preceding seedling stand is sent into the seedling stand transport path 9, the seedling stand 6 moves and the next seedling stand is moved into the seedling stand transport path 9. The seedling stand conveyor and the seedling stand are configured to operate in conjunction with each other so as to stop the seedling stand in accordance with the entrance of the seedling stand.

Problems to be Solved by the Invention Therefore, in this type of transplanting machine, when the preceding seedling stand is sent into the seedling stand transport path 9, the seedling loading stand 6 moves, and the next seedling stand moves into the seedling stand conveying path 9. It was necessary to set the initial seedling stand correctly so as to correspond to the entrance of the conveyance path 9.

However, in the conventional machine, it was difficult to confirm the setting position of the seedling stand, so it was easy to set the seedling stand incorrectly.

The present invention aims to eliminate the above-mentioned drawbacks and provides a device for confirming the set position of a seedling stand in a vegetable transplanter, which allows the set position of the seedling stand to be easily confirmed.

Means for Solving the Problems That is, the present invention allows potted seedlings grown in a seedling stand formed by partitioning the top surface of a rectangular bottom plate at regular intervals and connecting n number of seedling chambers with both sides open. In a vegetable transplanter configured to load potted seedlings on a tower and to plant the potted seedlings by extruding them from the seedling chamber of the seedling stand and dropping them to the ground surface using a seedling extruding rod that reciprocates as the machine moves, the seedling extruding rod Structure of a device for confirming the set position of a seedling stand in a vegetable transplanter, characterized in that a rotary claw that rotates 1/n every time the seedling table reciprocates is rotatably provided at the center of a display board divided into n equal parts. The main points are as follows.

Effect Since this invention is configured as described above,
As the machine moves, the extrusion rod protrudes and pushes out the potted seedlings from any seedling chamber in the seedling stand and drops them. When the seedlings are planted on the ground, the rotating claws move 1/2 inch in the meantime.
Rotate n times. Therefore, this rotary claw rotates once while n potted seedlings are pushed out and planted, and goes around the top surface of the display board divided into n sections.

Embodiment To explain this invention with reference to an illustrated embodiment, the fuselage is composed of a front fuselage 1 and a rear fuselage 2. The front fuselage 1 is supported by drive wheels 3, and the rear fuselage 2 is supported by ground wheels 4 so as to be freely movable. There is. An underframe 5 is fixedly provided on one side of the rear body 2, and a seedling stand 6 is mounted on the underframe 5 so as to be slidable back and forth.
The seedling stand 6 is provided with a large number of cassette stands 7 on which the seedling stands A are placed in parallel, and on one side of the seedling stand 6 there is a cassette stand 7 and a partition located at the center of the cassette stand 7. The plates 8 are arranged in parallel in a comb blade shape. This partition plate 8 is provided so that the seedling stands A placed in parallel on the cassette stand 7 do not come into contact with each other.

Reference numeral 9 denotes a seedling stand transport path, which is provided at right angles to the frame 5 so that any seedling stand A on the seedling stand 6 can be freely inserted therein. A seedling extrusion rod 10 is provided at the center of the seedling stand transport path 9 so as to be able to protrude rearward across the transport path 9. The potted seedlings P pushed out by the seedling pushing rod 10 fall to the ground surface and are planted by the planting device 11. Further, a feed pawl 12 is swingably provided at the bottom of the seedling stand conveyance path 9 to convey the seedling stand A on the conveyance path 9 toward the extrusion rod 10.

An empty box recovery device is provided at the edge of the seedling stand conveyance path 9. The empty box recovery device consists of a receiving stand 13 and a box 14, and the seedling stand A sent out from the seedling stand transport path 9 is reversed by a rotary claw 15 provided on the receiving stand 13 and stored in the box 14. It is configured.
A rotating shaft 16 of the rotating claw 15 is rotatably provided at the center of a display board 17 provided on one side of the pedestal 13, so that the potted seedling P pushed out by the pushing rod 10 falls to the ground surface. , is provided in conjunction with the grounding wheel 4 so that it rotates 1/n while being planted by the planting device 11, and rotates once while n pot seedlings P are planted. Moreover, since the display board 17 is divided into n equal parts, if there are n seedling chambers in the seedling stand A, the rotary claw 1
5 always indicates the seedling room number from which the potted seedling P was pushed out.

To explain the operation of this embodiment, first, the seedling stand A is placed on the cassette stand 7 of the seedling stand 6 and supported in parallel. Next, the seedling stand 6 is adjusted and moved back and forth, and the rearmost seedling stand A is opposed to the entrance of the seedling stand transport path 9 and stopped. When the seedling stand A is pushed in, the seedling chamber at the tip of the seedling stand A is positioned in front of the seedling pushing rod 10 and set. At that time, the rotating claw 15
If it is not pointing to "1", you can adjust it by lifting the rear fuselage 2 and rotating the grounding wheel 4.

When the driving wheels 3 are driven and the machine body runs, the seedling pushing rod 10 protrudes, pushes out the potted seedlings P from the tip seedling chamber, and then retreats. The pushed out potted seedlings P fall and are planted, but in the meantime, the feeding claw 12 swings, pushing the seedling stand A one space forward and stopping the second seedling room by positioning it in front of the seedling pushing rod 10. , the pot seedling P is pushed out in the same manner as above. In this way, the original seedling stand A is transferred to the seedling stand transport path 9.
When the seedling stand 6 is fed in, the seedling stand 6 is moved backward by one booth, and the next seedling stand A is opposed to the entrance of the conveyance path 9 and stopped. Then, the feeding claw 12 catches the seedling stand A and sends it into the seedling stand transport path 9 following the preceding seedling stand A. While a large number of potted seedlings are continuously planted in this way, the first empty seedling stand A is placed in the cradle 13 of the empty box collection device.
pushed to the top. The seedling stand A is then turned over by the rotary claw 15 and housed in the box 14.

However, this rotary claw 15 rotates by 1/n when one pot seedling P is pushed out, and rotates while indicating the section of the display board 17 divided into n equal parts, so if you look at the number indicated by the rotary claw 15, , it is possible to easily check from which nursery room of the seedling stand A the potted seedling P is pushed out.

Therefore, even if there is some trouble during work and it is necessary to replace seedling stand A during planting,
If the seedling chamber indicated by the number indicated by the rotary claw 15 is located in front of the extrusion rod 10, the planting operation can be continued as it is.

Effects of the Invention According to the present invention, the rotary claw rotates once at the center of the display board divided into n equal parts while the potted seedlings are pushed out from the n seedling rooms and successively planted on the ground surface. Because of this provision, the position of the rotary claw has the effect that the set position of the seedling stand relative to the seedling stand conveyance path can be confirmed extremely easily.
