DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A seeder according to an embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a transfer conveyor as a seedling raising box transfer device, which is driven and rotated by a motor to the seeding table 3 so that the seedling raising box a is transferred in the direction of arrow i. Reference numeral a is a seedling raising box, which is placed and conveyed on the transfer conveyor 1 in a state where a seedling raising device b made of paper or a synthetic resin material is put therein. In the seedling raising device b, trapezoidal pyramidal trapezoidal pots are continuously formed in the left-right direction and the front-rear direction in a side view, and a sowing hole b'is formed on the upper part of each of the pyramidal trapezoidal pots. .

Reference numeral 4 denotes a floor soil supplying device, which is composed of a floor soil hopper 5 and a supply belt 6 provided under the floor soil hopper 5. The floor soil in the floor soil hopper 5 is the floor soil hopper 5 and the supply belt 6. From the gap formed between and, the supply belt 6 is rotated in the direction of B so that the floor soil can be supplied downward. Reference numeral 7 denotes a floor soil replenishing elevator, which is configured to replenish the floor soil into the above-mentioned floor soil hopper 5 from a floor soil tank provided separately.
In addition, below the transfer conveyor 1, there is provided a floor soil receiving portion 8 for receiving the floor soil dropped down during the floor soil filling operation,
The floor soil replenishing elevator 7 is also configured to return the floor soil received by the floor soil receiving portion 8 back into the floor soil hopper 5.

Reference numeral 2 is a vibrating device for vibrating the seedling raising box a transferred by the transfer conveyor 1. The vibration generator 2a in the shape of a rectangular column is supported by the seeding table 3 and driven and rotated by a motor. It is configured so that the belt can be moved up and down. This vibration device 2
Are provided in correspondence with the bed soil supply position of the bed soil supplying device 4, and the bed nursery box a can be vibrated when the bed soil is supplied to the seedling nursery box a.

Reference numeral 9 is a leveling plate, 10 is a compression roller, and 11 is a leveling brush for leveling the top surface of the floor soil and removing excess soil. Reference numeral 12 denotes a seeding device, which is provided at the upper portion of the transfer conveyor 1 and has upper seeding holes b ′ of the seedling raising device b.
It is a general seeding device for point seeding, which is configured by a seeding hole forming portion 13 that rushes into the ground to form a seeding hole in the bed soil and a seeding device 14 that seeds in each of the seeding holes.

Reference numeral 15 is a soil covering device, which is a soil covering hopper 1.
6 and a supply belt 17 provided below the supply belt 17, the soil in the soil cover hopper 16 rotates in the direction of “H” from the gap formed between the soil cover hopper 16 and the supply belt 17. This allows the soil to be supplied downwards. Reference numeral 18 denotes a leveling brush, which removes excess soil by leveling the top surface of the floor soil evenly.

Reference numeral 19 is a watering device. In the configuration of the above example, when the nursery box b is put in the nursery box a and is transferred by the transfer conveyor 1, the nursery box a is vibrated by the vibrating device 2 and the floor soil is supplied from above by the floor soil supplying device 4. Therefore, it is possible to perform an appropriate amount of floor soil filling work while being properly packed. Then, the upper surface of the floor soil is leveled by the leveling plate 9, the compression roller 10, and the leveling brush 11 to remove excess soil,
Each pot b is sowed by the sowing device 12. afterwards,
The soil is covered by the soil cover device 15, leveled by the leveling brush 18, and irrigated by the irrigation device 19, and the seeding work is completed.

3 to 5 show another example of the floor soil supplying device 4, which is a floor soil hopper 5 and a floor soil filling rotator 21 and a diffusion blade 22 which are rotatably supported by a shaft 20 in the interior thereof for rotation.
It is composed of and. As shown in FIGS. 4 and 5, the floor soil filling rotating body 21 is provided with the horizontal shafts 21a ... on the lower end of the shaft 20 in four directions, and the upper portions of the rubber plates 21b. The lower part is provided so as to be in sliding contact with the upper surface of each pot b ...

At the same time, the floor soil replenished by the floor soil replenishing elevator 7 in the floor soil hopper 5 is diffused by the diffusion blades 22 to supply the floor soil to the seedling raising box a, and the floor soil filling rotating body 2
No. 1 can fill the floor soil. Figure 6
Shows an example of a case where the seedlings obtained by germinating and raising seedlings after the above-mentioned seeding work are transported by the carriage 23.

The carrier truck 23 is framed by a prismatic steel material, and the nursery boxes a can be placed on the shelves 24 in multiple stages, and casters 25 are provided at the bottom thereof. Then, when the seedlings have grown up to the time when they can be planted in the field, the seedling raising boxes a ... Are put in the respective shelves 24 ... of the carrier truck 23, and the carrier truck 23 is placed on a truck and transported. During this transportation, if the seedlings are exposed to strong wind or sunlight, they will dry and the seedlings will weaken and the leaves will curl. In other words, if you shield yourself from the wind and sunlight, the seedlings will be steamed and the seedlings will be hurt, and the seedlings will not be exposed to any light, and the leaves will grow white. Therefore, when the light-shielding curtain 26 having air permeability, light-shielding property, and heat-shielding property is covered over the transporting vehicle 23 from above, the pain of the seedling can be prevented. (A silver shading curtain is suitable as the shading curtain 26 having air permeability, light shielding property, and heat shielding property.) Further, instead of the above light shielding curtain 26, the truck hood itself is provided with air permeability, light shielding property, It may be configured by a light shielding member having a heat shielding property. In addition, 27 and 27 are fasteners, and one side surface of the light-shielding curtain 26 can be opened and closed so that it can be easily attached to and detached from the carriage 23.

FIGS. 7 and 8 show an example of irrigation at the time of raising seedlings. The seedling raising boxes a ... are arranged on the ground, and the watering device 28 is moved from above to the juxtaposed direction of the seedling raising boxes a. To irrigate. At this time, since the left and right side portions are easily dried with respect to the central portion of the seedling raising box a ..., in order to increase the irrigation amount on the left and right side portions, I try to increase the amount of irrigation.

More specifically, the irrigation valve 28a.
And 28b have the following configuration. The screw 33 formed on the inner peripheral portion of the fountain cap 32 is screwed into the screw 31 provided on the outer peripheral portion of the drainage port portion 30 formed on the water supply pipe 29 to obtain the state of FIG. 8, and the adjusting valve 34 is provided therein. The spring 35 is provided so as to urge it to stop water. 36
Is a packing for preventing water leakage. At this time, if the fountain cap 32 is screwed deeply, the urging force of the spring 35 is increased and the amount of water fountain is reduced. The water fountain action will be described. The water pressure in the water supply pipe 29 pushes down the adjusting valve 34 against the urging force of the spring 35, and the water supply pipe 29 passes through the drain port 30 and the fountain port of the fountain cap 32. Water is sprinkled from 37.

Therefore, the irrigation valves 28b-2 on the left and right sides
Fountain cap 32 of irrigation valve 28a located in the center of 8b
Is deeply screwed in to reduce the amount of irrigation of the central irrigation valve 28a.
