Sweeping it back to the side, JLI with awn! The awns of the paddy arrive at the rotating brush 47, rotate together, and are collected into the seed receiving box 61. Therefore, only the seed rice without a seed moves into the seed transfer groove 21, so that it becomes easier to fit into the fitting groove 19, and each seed is moved reliably one by one. At this time,
Rotating brush 4 for smoothing I and E seeds moving in the seed moving groove 21
7 needs to have its tip positioned on the upper surface of the insertion r-movement groove 21. Adjustment j+i+ screw 63 is adjusted by bringing its lower ψ1" part 65 into contact with a receiving plate 64 formed by bending the end of the side plate 52.53 of the seeding device 12 inward, and then tightening the rotating arm 49.50. When the adjusting screw 63 is rotated clockwise, the horizontal rod 59 rises, and when the rotating arm 49.50 is rotated around the drive shaft 51, the horizontal rod 59 descends.
Since the rotary arm 49.50 is rotated downward around the drive 11+51, the shaft 48 of the one-rotation brush 47 is rotated by the side plate 5.
2. Adjust the degree of contact of the one-rotation brush 47 with the spiral roll 16 by moving up and down in the elongated hole 95 of 53.The storage case 2 is further advanced by the guide roll 93, and is placed on the floor by the floor supply device 89. is supplied and sowing is completed.

As already mentioned, in the past, early seedlings for rice transplanters have progressed from seedlings sown in bulk to using σ1 seedlings in rows.
Recently, paperbot bacteria has appeared. The stem of this top b'F is thicker and stronger than that of the conventional one, so it has a tfr structure that is resistant to cold damage. Therefore, it is quite seasoned, but in a small pot, 1
Until now, there was no device that could sow grains one by one in a bucket.
It was difficult to create Paperbok + and rYi, and in field jL1, it was difficult to thin out the seeds after sowing one seed.
