The seedling plant 20 transplants the seedlings 22 grown in the next seedling box 21. A plurality of pots 21b are integrally formed on a flexible resin plate 21a to form a seedling box 21.
The pot 21b is composed of 14 pieces arranged side by side, and constitutes a valve into which an extrusion pin can protrude into the bottom. The feed holes 21c are provided on both sides of the resin plate 21a at the same pitch as the pot 21b in the front-rear direction. And each pot 2
1b is filled with soil, seeds (one onion) are sown on the soil, and the soil is covered with the seeds. After a predetermined number of days have passed while watering, the seeds germinate and the seedlings 22 (FIG. 4) grow. At this time, the roots extended in the pot 21b are entangled to form the root pot 22a (FIG. 4).

The seedling plant 20 is constructed as follows. Seedling mounts 23 that are inclined upward in the front are arranged in two stages, upper and lower, so that seedling boxes 21 with the seedlings 22 facing upward can be placed on each. After the rails 24 extend downward from both sides of the rear end of each seedling mounting table 23, the upper and lower parts integrally extend downward, bend in a U-shape and reach the receiving frame 25. Then, both sides of the seedling box 21 fed from the upper or lower seedling mounting table 23 are held by left and right rails 24 and are intermittently fed by feed claws (not shown).

The left and right sides of the carrier 26 are attached by a pair of links 27, and the swing of the carrier reciprocates between the rear and the lower of the rail 24. When the carrier 26 rises and comes after the rail 24, the 14 seedlings 22 in a row are pushed out of the seedling box 21 and the carrier 26 is pushed out.

Swings while rolling in the cam groove 32 a, and the implantation rod 34 swings around the rotation shaft 33.

A leveling roller 36 (FIG. 1) is provided in front of the pair of seedling units 20.
Is intended to level the ground on which it is transplanted. The four groovers 37 (FIG. 1) are arranged side by side,
As you advance, four graft grooves are created on the ground. A pair of guide plates 38 (FIG. 4) are provided at the outer ends of the respective belt conveyors 28 downward.

A pressure reducing wheel 39 is fixed so as to cover the outer periphery of each rotating case 31. And the cam groove 32a
, The rotating implantation rod 34 projects radially (upward) on the horizontal axis 30, rotates 90 degrees counterclockwise (FIG. 4), and assumes a substantially horizontal posture in front of the horizontal axis 30. The holding portion 34a at the tip of the root holder 22a holds the root pot 22a of the seedling 22 carried to the end of the belt conveyor 28 from above. When the rotation of the implantation rod 34 proceeds, the implanting rod 34 passes between the left and right guide plates 38 while standing upright, the holding portion 34a protrudes into the transplantation groove at the lower end, and the seedlings 22
At the position at the lowermost end of No. 9, it moves upward while maintaining its upright posture as it advances, and the seedlings 22 are transplanted into the groove while the compression ring 39 breaks down the transplanting groove.

The implantation frame 29 between the left and right seedling-planting units 20 is provided in common. When the cavity of the pot 21b is formed in a cylindrical shape, the root pot 22a is formed in a cylindrical shape. When the surface of the holding portion 34a is formed as a curved surface 34b (FIG. 7) recessed along the outer surface, lateral displacement of the seedling 22 is prevented, and stable transplantation is performed.

FIG. 8 shows another seedling planting machine. This seedling transplanter has the same configuration as the above-described seedling transplanter except the one-stage seedling mounting table 23, and the description of the same parts is omitted to avoid duplication. A pair of left and right belts 40 and 41 are provided below the outer end of the belt conveyor 28, and the root pot 22a of the seedlings 22 carried out by the belt conveyor 28 is sandwiched between the two and sent downward (FIG. 10). .
