If the diameter of the suction hole 16 is set smaller than the size of the seed grain 30, even if a plurality of seed grains 30 are sucked into the suction recess 14, one seed grain 3
0 closes the suction hole 16 and is adsorbed.
As the suction force is no longer applied to
One seed grain 30 is adsorbed by air and supported by the suction recess 12.

FIG. 3 is an explanatory view showing an embodiment of the suction support device 10. As shown in FIG. That is, as shown in FIG. 2, seed grains are sucked and supported one by one in the suction concave portion 14 formed in a bell shape . The embodiment shown in Figure 3, in order to sow a plurality of seed particles in one place, is two suction recesses 14a corresponding to the sowing position one point, and 14b that are arranged adjacently. The shapes of the suction recesses 14a and 14b are the same as in the example shown in FIG.
The inner surface is formed in a bell shape, and each suction recess 14a, 14b is formed.
The suction holes 16a and 16b are opened on the inner bottom surface of the suction hole 16a.

A seeding hole 44 is opened at the bottom of the guide hole 42, and the seed that has fallen into the guide hole 42 falls from the seeding hole onto the seeding bed 4 and is sown. Reference numeral 46 denotes a projection provided around the seeding hole 44. At the time of seeding, the projection 46 is placed on the upper surface of the seeding bed 4 and the guide receiving plate 40 is arranged. Since the guide receiving plate 40 is made of a conductive material, the seeds do not adhere to the guide receiving plate 40 due to static electricity or the like, and the seeds can be sown at a predetermined position on the seeding bed 4 reliably.

The operation of actually seeding using the suction support device 10 is as follows. First, the vacuum generating device 20 is operated and air is sucked from each suction recess 14 provided in the suction support device 10 so that the seeds are stored in the suction recess 14. Adsorb and support the grains. The seeds are stored in a container having a fixed area, and the seed particles are easily sucked and supported one by one in the suction recess 14 by bringing the suction support device 10 closer to the container in which the seeds are placed.

Next, while maintaining the negative pressure of the suction recess 14, the suction support device 10 is moved onto the guide receiving plate 40 arranged on the seeding bed 4, and the guide hole 42 and the suction recess 14 are aligned. Then, the air suction of the vacuum generator 20 is released. As a result, the seeds fall from the suction recess 14 into the guide holes 42. Multiple suction recesses corresponding to each seeding position
