An air passage (not shown) is formed inside the column member 40, the connecting member 42, the U-shaped arm 45, and the shaft 44, and as described above, the intake / exhaust port 33 inside the suction unit 15 and the chamber 43. The inside of the chamber 43 is communicated with each other, and the inside of the chamber 43 can be sucked and pressurized by the intake / exhaust means constituted by the blower 16. As shown in FIG. 7, one surface (upper surface in FIG. 7) of the chamber 43 is a sowing surface 46 for sowing seeds, and the other surface (lower surface in FIG. 7) is a pressure suppressing surface 47 for suppressing soil. It has become.

A large number of seed holding holes 48 are formed in the sowing surface 46, and the inside of the chamber 43 is sucked to hold the seeds in these holding holes 48 and all the pots 5 of the tray 4 can be operated once. You can sow the seeds. At the periphery of the sowing surface 46, a tank 50 for stocking the seeds and a rail 51 for collecting again the excess seeds not sucked by the holding holes 48 in the tank 50 are attached. A follower 52 is attached to the back of the tank 50 so as to contact the vertical guide 8 and regulate the descending position of the chamber 43 when the seeding operation is performed. In addition, a handle 53 is attached to the outside of the sowing surface 46 for grasping when moving the chamber 43 with the sowing surface 46 facing upward, and the inside of the sowing surface 46 is used for adsorbing seeds. A vibrator 54 for applying vibration to the sowing surface 46 is provided. Vibration of the vibrator 54 is transmitted to the seeding surface 46 via a hard elastic body (urethane rubber or the like) 56 attached to the diaphragm 55.

On the other hand, a compression tool 60 is attached to the compression surface 47. A large number of compression protrusions 61 are provided on the surface of the compression tool 60. As shown in FIG. 9, the pressure suppressing projections 61 are arranged so as to correspond to the respective pots 5 of the seedling raising tray 4. In addition, around the pressure suppressor 60 as described above, a handle 62 for grasping when moving the chamber 43 with the pressure suppressing surface 47 facing upward, and a vertical guide 8 when performing the pressure suppressing work. A follower 63, which is in contact with and regulates the descending position of the chamber 43, is attached.

Then, in the seeding machine configured as described above, the seedling raising tray 4 in which the pot 5 is filled with the soil is preliminarily supplied on the auxiliary base 9 in an overlapping manner. Then, one of the seedling-raising trays 4 is taken out from the inside, and the seedling-raising tray 4 is set in a predetermined position on the table 3 while the position of the guide 6 is regulated. Next, as shown in FIG. 1, with the pressure suppression surface 47 facing downward, the handle 53 is grasped and operated, and the chamber 43 is regulated in position by the horizontal guide 7 and the vertical guide 8 and the chamber 43 is moved to the alternate long and short dash line in FIG. Lower to the height indicated by 43 '. As a result, the pressure-reducing tool 60 attached to the pressure-reducing surface 47 is pressed from above the seedling raising tray 4, and the pressure-reducing projections 61 are fitted into the pots 5 to form seed planting depressions on the potted soil surface. .

After that, the chamber 43 is once raised. Then, while vibrating the seeding surface 46 with the vibrator 54, the seeds in the tank 50 are flown onto the seeding surface 46, the blower 16 is operated to make the inside of the chamber 43 a negative pressure, and the seeds are adsorbed to the respective holding holes 48. To do. After the seeds have been adsorbed and held in this manner, the excess seeds that were not sucked by the holding holes 48 while being guided by the rails 51 are collected again in the tank 50, and the chamber 43 is inverted so that the seeding surface 46 faces downward. .

Then, the handle 62 is grasped and operated, and the chamber 43 is lowered to the height shown by the one-dot chain line 43 ″ in FIG. 10 while controlling the position by the horizontal guide 7 and the vertical guide 8. 29 is depressed to rotate the rotating plate 21 in the suction portion 15 to the position shown in Fig. 6 to switch the intake / exhaust port 33 to the state in which it communicates with the opening 25 of the hose 20. Thereby, the blower The air discharged from the exhaust port 18 of 16 pressurizes the inner portion of the chamber 43 to drop the seeds held in the holding holes 48 of the sowing surface 46, and the seedlings 60 are applied to the soil surface of each pot 5 by the pressure suppressor 60. The seeds are sown in each of the formed planting recesses, and the seedling-growing tray 4 after the seeding work is carried into the next step such as covering with soil. It is set, and the same process is repeatedly.

However, in the above-described seeding machine, if the seeding surface 46 and the pressure suppressor 60 are configured to be exchangeable, in the case where the size of the tray 4 or the pitch and the number of the pots 5 are different, Is also available and convenient. Further, the shape of the compression squeezing protrusion 61 is not limited to the substantially hemispherical shape as described in the above embodiments, and a cylindrical compression squeezing protrusion 61 ′ as shown in FIG. 11 or a circular cone-shaped squeezing protrusion as shown in FIG. It is convenient to prepare various shapes such as 61 ".

Further, seeds are poured onto the surface of the sowing surface 46, and the inside of the chamber 43 is set to a negative pressure so that the seeds are adsorbed to the respective holding holes 48, but the sowing surface 46 is flat as shown in FIG. If so, it may take time until the seed a is uniformly adsorbed in the holding holes 48 one by one. Therefore, as shown in FIG. 14, a slightly concave portion 70 is formed around the holding hole 48, and a rubber coating layer 71 is formed on the surface of the sowing surface 46 as shown in FIG. It is convenient to make it easier for the seeds that have flowed onto the seeds 46 to enter the concave portion 70, and to be able to handle seeds a1, a2, and a3 having different sizes and shapes within a wide allowable range. Further, a support plate 72 is provided inside the chamber 43 so that the seeding surface 46 is not dented when the chamber 43 is under negative pressure, and the seeding surface 46 is supported from the inside. The seeds flow smoothly on the surface, and there is an advantage that the seeds are easily adsorbed to the holding holes 48.
