Description

[Detailed description of the invention] The present invention relates to a seedling feeding device for a transplanter, and in particular, it is designed to directly load a seedling box into the transplanter, extrude the seedlings from the seedling box, and divide and transplant the extruded seedlings. This invention relates to a seedling feeding device used in a transplanter of the type described above.

Transplanting machines that are commonly used today create mat-shaped seedlings of a predetermined size by sowing and raising seedlings throughout the interior of the seedling box, and then load these seedlings into the seedling tank of the transplanter and use the transplanting device. Most of the seedlings are divided and transplanted, which necessitates the complicated work of removing the mat-shaped seedlings from the seedling box and transferring them to a transplanter.

Recently, in order to eliminate the troublesome work of transferring seedlings, a method has been developed in which the seedling box itself is directly loaded into a transplanter, moved in a predetermined direction, the seedlings are pushed out from the seedling box, and the extruded seedlings are divided. A transplanting method has been proposed in which the seedlings are planted using a transplanting method, and a transplanter and a seedling box suitable for the method1. It is necessary to reliably supply the water to the gutter at regular intervals.

The present invention was developed in view of these points, and when feeding seedling boxes to a transplanter continuously, the feeding pitch of the connecting part is set to be the same as the separation interval of the seedlings in the seedling box, and the feeding pitch of the connecting part is set to be the same as the separation interval of the seedlings in the seedling box. To provide a seedling feeding device for a transplanter that enables accurate and efficient transplanting work by linking a feeding operation and a seedling pushing operation.

Hereinafter, the present invention will be explained with reference to embodiments of the drawings.

In the figure, first of all, the seedling box 1 is surrounded by a side frame 2a that is erected.
, 2b, 3a, and 3b are rectangular in plan view. Inside the bottomless frame 4, wide partition frames 5 parallel to the short side frames 2a and 2b are arranged at regular intervals. A seedling growing section 6 is formed between the frames 5, and such a seedling growing section 6
A large number of narrow strip-shaped seedlings 7 are produced at equal intervals by filling the bed with soil and sowing and raising seedlings.

In addition, holes 8 for feeding the seedling box of the engaging portion are provided along the long side frames 3a and 3b of the frame body 4 for the seedlings 7 of the seedling growing section 6.
It is opened every time.

On the other hand, in the transplanting machine 9, a seedling box feeding roller 13 is placed in the vicinity of the planting part 12 at one end of the belt 11, and the seedling box feeding roller 13 is placed horizontally together with the seedling box tray 10. It is provided so as to rotate while engaging with the hole 8 of the box 1.

In the planting section 12, a seedling extrusion arm 16 is rotatably installed in a part 15 of a hopper between a belt 11 for conveying seedling boxes and a table 14 for a seedling box, which is installed horizontally at a distance from the belt 11. The seedling pushing arm 16 is attached via a rod 19 to a pulley 18 which is connected to a roller 13 for feeding the seedling box so as to rotate together with the roller 13 for feeding the seedling box via a belt 17. The feeding by the roller 13 and the rotation by the seedling push-out arm 16 are synchronized.

Below the hopper part 15, a cross-feeding belt 20 is installed horizontally, intersecting with the belt 11 that feeds the seedling box, and the seedlings that have fallen onto this cross-feeding belt 20 are transported in the left and right directions as shown in the figure. It is designed to be divided and implanted with a non-contact implant.

Thus, according to the present invention, the width of the short side frames 2a and 2b connected to each other is half S/2 of the mutual width S of the seedling growing section 6 containing the seedlings 7 inside the seedling box 1. Dimensioned.

In addition, the other seedling boxes 1' are constructed in exactly the same manner, and the dimensions of the short side frames 2a' and 2b' are also set in the same way, so that a plurality of seedling boxes 1, 1', or if they are connected using an appropriate locking means, the width of the seedling growing compartments 6, 6' at the connected part will be equal to the width of the seedling boxes 1, 6'.
1', so that the seedlings 7 are always fed at the same pitch.

During transplanting, when a plurality of seedling boxes 1, 1' are connected in a band shape and the seedling box holder is placed on the stand 10 and the belt 11 for feeding the seedling boxes, the belt 11 and the roller for feeding the seedling boxes 13, the seedling boxes 1, 1' are continuously fed toward the planting section 12 at a constant speed.

Then, when passing through the planting section 12, the seedling pushing arm 1
6, the strip-shaped seedlings 7 in the seedling growing section 6 of the seedling box 1 etc. are pushed out onto the lower transverse conveying belt 20, and then,
The strip-shaped seedlings 7 are divided and planted in the soil of the field while being fed in the left-right direction by the transverse feed belt 20.

As described above, according to the present invention, the seedling box is provided with an engaging part that is moved at intervals between the seedling partitions, and the seedling box feeding mechanism that engages with this engaging part and the seedling pusher that pushes out the seedlings from the seedling box are provided. Since the mechanisms are configured to work in synchronization, the movement of the seedling box and the pushing out of the seedlings from the seedling box are linked, ensuring a reliable supply of seedlings and allowing for accurate and efficient planting. However, when the seedling boxes are continuously fed in a joined state to the seedling box feeding mechanism side, the seedlings are arranged so that the interval between the seedling growing compartments at the joint of the seedling boxes matches the interval between the seedling growing compartments of the seedling box itself. Since the thickness of the side frame of the box is set, even if the seedling boxes are fed continuously, the joints will be in the same position as other parts, and the transfer pitch will not be distorted, allowing accurate movement and ensuring that each seedling box is fed in succession. It is possible to push out the seedlings growing in the seedling-raising compartment, and it is possible to take out the grown seedlings without damaging them.
