[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 via the sprocket 5 and the endless chain 8 to rotate the endless chain. Rotation of 8 turns bucket 9 into soil supply hopper 1
When it is turned upside down and rises in the scooping upper part 22 in 4, the soil is scraped off, and while scooping, it rises in the soil supply hopper 14. 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.

Then, of the soil that has fallen from the floor soil supplying device 35, the soil that has fallen without entering the seedling raising box enters the recovery hopper 69 of the soil recovery device 60, and the soil in the recovery hopper 69 collects the conveyor belt 63. The soil collected in the rear hopper 44 by being conveyed by the rear hopper 44 is pushed by the descending bucket 9 and passes through the passage opening 48 between the lower portions of the left and right frames 2 and 3. And then the upper part 22
Then, at the upper part 22 of the scooping, it is scooped up by the bucket 9 and rises.

In this case, the rotary motion of the lower rotary shaft 6 (rotation of the arm 54) is converted into a linear reciprocating motion by the rod 68 and transmitted to the input shaft 66, and one of the reciprocating motions is transmitted by the one-way rotation transmitting clutch 65. Since only the directional rotation is transmitted to the rotation shaft 64 of the drive roller 61, the recovery conveyance belt 63
Is an intermittent move. Therefore, since a large amount of soil is not returned to the rear hopper 44 at one time, soil clogging is prevented and the soil in the soil supply hopper 14 is securely fed.
5 to the floor soil supply hopper 36. Further, since the recovery / conveyance belt 63 is located below the recovery hopper 69,
There is no soil bridge phenomenon in the recovery hopper 69,
By the intermittent movement of the collecting and conveying belt 63, the collecting hopper 69
Since the soil inside is destroyed, the soil is prevented from adhering to the inner surface of the recovery hopper 69.

Further, in the method of transmitting rotation such as a chain or a belt, the rotation direction of the lower rotary shaft 6 and the rotation direction of the drive roller 61 do not match, and it is necessary to twist them, which not only complicates the structure, but also Although the soil collecting device 60 cannot be easily attached and detached, in the present invention, the arm 54 of the lower rotary shaft 6 and the input shaft 6 are not provided.
Soil recovery device 60 by simply attaching and detaching the rod 68 between 6 and
Can be attached and detached, and the main body of the bucket conveyor 1 can be easily transported.

[0023]

[Effect] The present invention is a soil supply hopper 14 for storing soil.
And the left and right side frames 2 and 3 which are long in the vertical direction with the lower part fixed to the soil supply hopper 14, and the upper rotary shaft 4 provided between the left and right side frames 2 and 3 and the chain 8 wound around the lower rotary shaft 6. In the soil supplying device configured to include the set of buckets 9 and located on the side of the soil supplying device 35 provided on the horizontal transfer table 34 for transferring the nursery box, the soil supplying device supplies the soil to the left and right sides. A rear hopper 44 communicating with the soil supply hopper 14 is provided on the lower rear side of the frames 2 and 3,
Between the rear hopper 44 and the lower part of the soil supplying device 35, a collecting and conveying belt 63 that collects and conveys the soil that has fallen from the soil supplying device 35 without entering the seedling raising box. The soil recovery device 60 is provided, and the recovery transport belt 63 is intermittently moved by transmitting the rotation of the lower rotary shaft 6 by a one-way rotation transmission clutch 65 provided on the rotary shaft 64 of the drive roller 61 of the transport belt 63. Since it is the soil supply device in the seedling box seeding device configured to do, since the recovery transport belt 63 transports the soil by intermittent movement, without returning a large amount of soil to the rear hopper 44 at a time, The soil can be prevented from clogging and work can be carried out smoothly and reliably. In addition to the fact that the soil bridging phenomenon does not occur in the collection hopper 69, the soil can be conveyed while collapsing the soil due to the impact of intermittent movement, so the collection ho Soil on the inner surface of the par 69 is prevented from adhering. Further, in the method of transmitting rotation of chain, belt, etc., the rotation direction of the lower rotary shaft 6 and the rotation direction of the drive roller 61 do not match, and it is necessary to twist the structure, which not only complicates the structure but also the soil recovery device. Although 60 cannot be easily attached and detached, in the present invention, the arm 54 of the lower rotary shaft 6 and the input shaft 6
Soil recovery device 60 by simply attaching and detaching the rod 68 between 6 and
Can be attached and detached, and the main body of the bucket conveyor 1 can be easily transported.
