[0018]

[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 supplying device 35 is energized, the seedling box transferred by the horizontal transfer table 34 reaches below the bed soil supplying device 35 and is not shown. The soil fed by the feeding device is supplied.

In this case, of the soil dropped from the floor 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 reach the upper part 22 of the scooping, and the scooping part 22 is lifted by the bucket 9 at the upper part 22 of the scooping part.

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 rotate.
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 carrying conveyor 62.
When configured by
Are collected by the rear hopper 44.

[0023]

According to the present invention, the soil supply hopper 14 having the front inclined plate 15, the left inclined plate 16, the right inclined plate 17, and the rear inclined plate 18 becomes narrower toward the lower portion and the scooping upper portion 22 is formed at the lower portion. Left and right side frames 2 and 3 which are long in the vertical direction and whose lower part is fixed to the supply hopper 14,
Soil supply device provided on a horizontal transfer stand 34 for transferring the seedling raising box, which includes a group of vertically swinging buckets 9 arranged in parallel in the vertical direction between the three and transport wheels 38 provided on the left and right frames 2 and 3. In the soil supply device which is located on the side of 35 and supplies soil to the soil supply device 35, the left and right side frames 2, 3
The rear side of the lower portion of the left and right side frames 2 and 3 is provided with a rear hopper 44 that communicates with the soil supply hopper 14 through a passage port 48 between the lower portions of the right and left side frames 2 and 3 as a soil supply apparatus in a seedling raising seedling device. Therefore, the soil recovery device 60 provided below the soil supply device 35 can be connected to the rear hopper 44, and the soil that has fallen can be easily collected without entering the nursery box.

Further, the soil collecting device 60 has a slanted collecting plate 61 which is slanted low as it approaches the rear hopper 44.
Since it is configured by, it can be easily attached to the soil supplying device.

Further, since the base of the inclined recovery plate 61 is pivotally attached to the rear hopper 44 by the shaft 63 so that the tip of the inclined recovery plate 61 is vertically rotated and vibrated, soil is prevented from adhering by vibration. it can.
