With the same configuration as D, a soil covering tank 10 is provided on the upper side supported by support frames 11..., and a soil covering hopper 12 for dropping the covering soil in the tank LO into the covering soil delivery section 3 is arranged on the lower side. The seeding device E uses the soil covering belt 14 which rotates in the horizontal direction in the section 13 to reach t! It is configured to supply covering soil little by little onto the sown seeds.

G is a bedding soil replenishing device, which is composed of a bedding soil replenishing hopper 15, a bedding soil conveying elevator 16, a soil sifting machine 17, and a bedding soil replenishing conveyor 18. replenish.

The bed soil replenishment hopper 15 is arranged so that the upper end of the hopper is aligned with the floor surface position so that soil can be easily replenished. This hopper 15 is configured to return soil spilled during the supply of soil to the hopper 15 by a soil return device 19 provided below the soil supply device for replenishing the soil. The return hopper 19a of the floor soil return tool 19 has
A shutter 19b is provided to remove the bed soil without returning it to the supply hopper 15.

The bed soil conveying elevator 16 has a large number of loose keratos for scooping up bed soil, which are attached to a rotatably driven belt, and lifts and conveys the bed soil to be replenished from the lower side of the bed soil replenishment hopper 15 upward. It is configured.

The soil sifting machine 17 is provided near the upper end f4 of the elevator 16, and is configured so that a sifting net 17a swings and vibrates. The soil transported by the elevator 6 is sieved here to a predetermined particle size.

The bed soil replenishment conveyor 18 is driven by a drive roller 20 that rotates in forward and reverse directions.
An endless conveyor belt 21 is placed over the driven rollers 20b and 20b, and rollers 22 are provided below the belt 21 to push the belt 21 upward. Then, below the rollers 22..., there is a guide plate 23, 23 which is inclined so that the soil naturally slides on the soil tank 3 side of the soil supply device or the soil covering tank 10 (QII) of the soil supply device F. When the drive roller 20a rotates in the normal direction, the soil sifted by the soil sifter 17 is replenished by the conveyor belt 21 into the soil tank 3 (!1) of the soil supply device, and when the drive roller 20a rotates in the reverse direction, Covering soil supply device F
is supplied to the soil covering tank 10 side.
