I do. 74 is a sponge provided inside the seed rice guiding cover 73, and 75 is an adjustment knob for adjusting the rotation of the motor 27.

(Operation) Next, the operation will be described.

Since the present invention has the above configuration, the vertical paddy is put into the vertical paddy supply hopper 2 and the seedling raising box is transferred by the transfer table 56,
When the motor 27 of the seed supply device 1 is turned on, the motor
The rotation of 27 is: drive shaft 28 → drive gear 29 → chain 32 → passive gear 31 → intermediate shaft
30 → small diameter drive gear 33 → chain 35 → large diameter passive gear 34 → rotary shaft 16 is transmitted to rotate the horizontal shaft feeding roll 9.

In addition, the rotation of the motor 27 is performed by the drive shaft 28 → the drive gear 29 → the chain 32 → the passive gear 31 → the intermediate shaft
30 → drive gear 45 → chain 46 → passive gear 44 → bearing 43 → intermediate gear 47 → chain 50 → passive gear 48 → passive gear 49 Are rotated respectively.

In this case, a bearing 43 is loosely fitted to the right end of the rotating shaft 16 of the horizontal shaft feeding roll 9, an intermediate gear 44 is fixed to the bearing 43, and an intermediate gear 47 is fixed to the bearing 43 inside the intermediate gear 44. Chain between the intermediate gear 47 and the passive gears 48 and 49.
Since 50 is wound, the horizontal shaft feeding roll 9 and the second rotation equalizing brush 17 and the first rotation equalizing brush 19 can be rotated at different rotation speeds, and the rotating shaft 16 is The central shaft of the horizontal shaft feeding roll 9 and the intermediate shaft for transmitting the rotation to the second rotation leveling brush 17 and the first rotation leveling brush 19 can be configured to be shared.

Then, the seed rice in the seed rice supply hopper 2 flows down on the flowing grain plate 4 to reach the seed rice supply unit 18, fits into the feeding recess 10 of the horizontal axis feeding roll 9, and rises by rotation of the horizontal axis feeding roll 9. Most of the excess seeds that have not been fitted into the feeding recess 10 that co-rotates with the horizontal-axis feeding roll 9 are returned to the seed feeding unit 18 by the first rotating leveling brush 19, and are leveled. Excess seeds that have not fit into the set-up recesses 10 that have passed below the leveling brush 19 are returned and leveled by the second rotating leveling brush 17.

Therefore, in the set-up concave portion 10 that has passed below the second rotating leveling brush 17, the seed rice fits in a horizontal line, is guided to the lower side by the seed rice guiding cover 73, falls down at the lowest point, and is accurately positioned. Then, a certain amount of seed paddy is sown in the nursery box.

Also, by changing the chain 32 wound around the small-diameter drive gear 33 and the large-diameter passive gear 34 to the large-diameter drive gear 36 and the small-diameter passive gear 37, the rotation speed of the horizontal-axis feeding roll 9 is changed to sow the seed. The amount can be adjusted. In addition, motor 27
The seeding amount can also be adjusted by changing the number of rotations with the adjustment knob 75.

(Effect) The present invention provides one or a plurality of rotary leveling brushes 17 for leveling the seed rice above the horizontal axis feeding roll 9 having the feeding recess 10 formed on the outer peripheral surface thereof. And a seedling box sowing device in which the rotating flat brush 17 can be rotated by one motor 27. a. An intermediate shaft 30 is provided between the motor 27 and the horizontal shaft feeding roll 9; The shaft feeding roll 9 is configured to be rotated by the motor 27 via the intermediate shaft 30. b. The intermediate gears 44 and 47 are loosely fitted on the rotating shaft 16 of the horizontal shaft feeding roll 9, and Reference numeral 17 designates a rotating brush and a rotating brush of the seeding device for a seedling box, in which the intermediate shaft 30 and the rotating shaft 16 of the horizontal shaft extending roll 9 are rotated at a different rotation speed from the horizontal shaft extending roll 9 as an intermediate axis. Since the rotation mechanism is used, the second rotation of the rotating leveling brush 17 is performed. Since omit intermediate shaft, an effect that the structure is simplified.
