[0017]

[Operation] Next, the operation will be described. When the soil is fed into the soil supply hopper 14 and the motor 28 is energized, the motor 28 rotates the upper rotary shaft 4, and the lower rotary shaft 6 of the bucket conveyor is rotated through the sprocket 5 and the endless chain 8 so that the endless end is rotated. Due to the rotation of the endless chain 8, the bucket 9 reverses at the upper part of the scooping portion 22 in the soil supply hopper 14 and scrapes up the soil when rising, and rises in the soil supply hopper 14 while scooping. Since the preceding bucket 9 scrapes up the soil and then rises in the shielding plate 23, the soil in the soil supply hopper 14 drops toward the upper part 22 of the scoop before the succeeding bucket 9 reaches the upper part 22 of the scoop. The bucket 9 of is surely scraped off the soil and rises.

When the bucket 9 rises, however, it is thrown at the upper position, and the thrown soil flows down on the supply gutter 33 and enters the floor soil supply hopper 36 of the floor soil supply device 35 to remove the soil. After the supply is completed, when the seedling raising box is supplied to the horizontal transfer table 34 and the bed soil supply device 35 is energized, the seedling box transferred by the horizontal transfer table 34 reaches below the bed soil supply device 35 and is not shown. The soil fed by the feeding device is supplied.

In this case, of the soil dropped from the bed soil supplying device 35, the soil that has not fallen into the seedling raising box falls onto the inclined recovery plate 61 of the soil recovery device 60 and is inclined. 61 is flowed down and collected in the rear hopper 44, and the soil collected in the rear hopper 44 is pushed by the descending bucket 9 to pass through the passage port 48 between the lower portions of the left and right frames 2 and 3. To the upper part 22 of the scooping part, and the scooping part 22 is lifted up by the bucket 9 at the upper part of the scooping part 22.

Further, even if soil is accumulated on the inclined recovery plate 61, the inclined recovery plate 61 has its base portion pivotally attached to the rear hopper 44 by a shaft 63 so that the inclined recovery plate 61 can be rotated.
Since one end of a rod 64 is pivotally attached to the shaft, and the other end of the rod 64 is pivotally attached to the shaft 55 of the arm 54, the inclined recovery plate 61 vibrates by the rod 64 that moves back and forth, and the soil is smoothly removed. It is made to flow down to the rear hopper 44.

In addition, the soil collecting device 60 is connected to the conveyor 62.
When configured by
Are collected by the rear hopper 44.

A shield plate 23 surrounding the ascending bucket 9 is attached to the inner edges of the left and right rear inclined plates 18 of the soil supply hopper 14, and the left and right side plates 25 of the shield plate 23 are provided on the respective side portions thereof. Since the soil agitator 50 is provided, the arm 54 rotates around the rotary shaft 6 by the rotation of the lower rotary shaft 6, and the rear shaft portion 53 of the soil agitator 50 axially attached to the arm 54 has a bearing member 56. The front side shaft portion 51, which is continuously guided by the rear side shaft portion 53 via the bent portion 52, vertically reciprocates at both positions of the ascending path of the bucket 9,
The soil in the soil supply hopper 14 is agitated. Therefore, even if moist soil or the like is supplied, it is agitated, so that the hopper 14
The occurrence of the bridge phenomenon of the soil inside is prevented or destroyed, and the soil is allowed to smoothly flow down to the upper part 22 of the scooping pad, and the bucket 9 is set at the upper part 2 of the scooping part.
2 Scoop up enough soil to raise it efficiently.

[0023]

According to the present invention, the soil supplying hopper 14 having the lower upper part 22 formed by the front side sloping plate 15, the left side sloping plate 16, the right side sloping plate 17, and the rear side sloping plate 18, and the soil supplying hopper 14 having a lower part. The left and right side frames 2 and 3 which are fixed in the up and down direction, and the up and down rotating bucket 9 group which is arranged between the left and right side frames 2 and 3 in the up and down direction. Since the soil supplying device is used in the seedling raising seeding device provided with the reciprocating soil stirring body 50, the occurrence of the bridging phenomenon of the soil in the hopper 14 is prevented or destroyed to smoothly scoop the soil. Flow down to
The bucket 9 scoops up the soil sufficiently flowing down to the upper part 22 of the scooping and efficiently raises it.
