2. Description of the Related Art A seedling raised in a mat shape in a rectangular seedling box is transplanted by a seedling transplanter, and the seedling is called a seedling.
I can't grow it big. On the other hand, in early cultivation and cold regions, transplantation of middle and adult seedlings is required. For this reason,
Putting soil in each pot of a pot-type seedling raising container in which a plurality of pots are formed on a soft synthetic resin plate to form a seedbed for each plant to grow a seedling, and taking out the seedling from the seedling raising container Seedling transplanters are used for transplantation. In this seedling transplanter, a seedbed transfer device is configured to simultaneously push the seedbeds out of the pots of the pot-type seedling containers arranged side by side, place the seedbeds on a horizontal feed belt, and transfer the seedlings by the horizontal feed belt. The nursery beds transferred by the nursery transfer device are sequentially inserted into the mud with a nursery transplanting tool at the end of the lateral feed belt.

[0003]

In the nursery transfer apparatus of the prior art, when the nursery is pushed out from the pot, if the nursery is pushed out so that the resistance to push out the nursery from the pot is too small, the nursery can be moved to the side of the nursery. The pushing on the feed belt is disturbed, and the seedbed pushed out of the pot is not supplied to an appropriate position on the transverse feed belt, so that a plurality of seed beds are irregular on the transverse feed belt. The present invention is intended to solve the problem by placing a nursery bed extruded from a pot at a predetermined position on a lateral feed belt.

Next, an embodiment of the present invention will be described. In a seedling transplanter which is an example of the transplanter of the present invention, a seedling raising container 1 as shown in FIG. 1 is used. The seedling raising container 1 is made of a somewhat soft synthetic resin, and is particularly flexible in the longitudinal direction. Pots 1a each having a frustoconical shape and a narrow bottom surface are provided side by side in the front, rear, left and right directions. After putting floor soil into the pots 1a from the upper opening side of each of the pots 1a, a few seeds are set. A seedbed is formed by sowing paddy, and then the seedlings are grown to medium and adult seedlings. A cross-shaped hole is provided on the lower surface of the pot 1a, and when a pin 14 described later is inserted, the floor soil is extruded together with the seedling. Also, feed holes 1b are provided at both left and right ends.
Is provided, and is adapted to be sent downward on the seedling mounting table by a claw that engages therewith.

As shown in FIG. 2, an attachment frame 3 is attached to a rear end of a link 2 projecting rearward from a traveling vehicle body (not shown).
Are provided, and are moved up and down by the rotation of the link 2 by the hydraulic cylinder. The center of the main gear box 4 is mounted so as to rotate left and right with a rolling shaft 5 in the front-rear direction. The three seedling mounting tables 6 are arranged at equal intervals in the left-right direction from the upper side to the rear side of the main gear box 4 so as to be inclined, so that a six-row seedling planting machine is provided as described later. Each seedling platform 6
When viewed from the side, after extending in a straight line below the slope, it is formed in an S-shape, followed by a horizontal portion, and then extending upward on the slope and connecting its end to the empty container receiver 7. I have.

As shown in FIG. 3, a pair of planting cases 8 and 9 extend rearward from the main gear box 4 between the center and the seedling rest 6 next to and outside the outer seedling rest 6, respectively. . Fig. 2.
As shown in FIGS. 3 and 4, a pair of lateral feed belts 10 are provided side by side on the horizontal portion of each seedling mounting table 6. Each lateral feed belt 10 is supported laterally by rollers and stretched laterally, each outer roller is rotated by a drive shaft 11, and each upper surface faces outward with respect to the center of the seedling mounting table 6. It is made to turn. Further, the lateral feed belt 10 is provided on its surface with protrusions 10a at the left end thereof at intervals corresponding to the horizontally arranged pots 1a of the seedling raising containers 1, and slightly below the protrusion of the S-shaped curve of the seedling mounting table 6. By arranging, the left end is made to approach the seedling mounting table 6.

The seedling mounting table 6 has an inclined straight portion provided by a bottom plate and plates on both side walls, and an S-shaped portion formed by a pair of upper and lower rods 12,1.
The lower rod 13 is connected to the empty container receiver 7. And the seedling raising container 1 put on this
Is sent downward by a claw having a well-known configuration facing the feed hole 1b at the end. Therefore, this seedling platform 6
Constitutes a nursery vessel transport means for sending the nursery vessel 1 downward. A plurality of pins 14 are arranged side by side on the front side of the S-shaped portion of the seedling mounting table 6, reciprocate in the front-rear direction under power, and when moved rearward, are pushed into the pot 1 a from the lower surface side of the pot 1 a. Then, the seedbed is pushed together with the seedling toward its leaf tip side, that is, the opening side of the pot 1a, and is pushed out above the lateral feed belt 10. Therefore, the plurality of pins 14 serve as an extruding tool for pushing out the seedbed from the pot 1 a of the seedling raising container 1.

A mounting plate 15 is provided above the upper portion of the S-shaped portion of the seedling mounting table 6, and a plurality of separating rods 16 are located between the left and right pots 1a (between the left and right seedlings). It extends from the mounting plate 15 toward the seedling raising container 1 side, and is inserted between each descending seedling to loosen the entangling of the left and right seedlings. A plurality of receiving rods 17 extend downward from the tip of the separation rod 16 at the lower end, and the surfaces of the floor extruded by the pins 14 respectively hit the front sides thereof,
After stopping the movement to the rear side, it is dropped on the lower lateral feed belt 10. Therefore, the plurality of receiving rods 17 constitute a receiving tool that comes into contact with the seedbed pushed out by the plurality of pins 14.

The seedlings dropped on the lateral feed belt 10 are sent left and right with respect to the center of each seedling mounting table 6, and then pushed down by the implanting rods 18 rotating at the lateral ends. Transplanted in mud, 6 rows of seedlings are made. Implant rod 1
As is well known, when the cam 8 in the drum 19 assumes a substantially vertical lower position, it rises while maintaining that posture,
Press the seedlings into the mud in a vertical position. Therefore, the implantation rod 18 is a nursery transplanting tool for transplanting the nursery into a field.

Therefore, the seedbed and the seedlings pushed out from the pot 1a of the seedling raising container 1 onto the lateral feed belt 10 are received by the receiving rod 1
7, the movement of the pin 14 in the pushing direction, that is, the rearward direction, is stopped or suppressed. Therefore, the transplanting depth of the nursery bed in the field by the implantation rod 18 can be made appropriate,
The growth of seedlings can be satisfactorily stabilized. Further, since the front and rear positions of the plurality of seedbeds pushed out by the plurality of pins 14 and arranged side by side on the lateral feed belt 10 are aligned, the transplantation depth of the seedbeds transplanted to the field is uniform, and there is no uneven growth of seedlings.
