The seeds in the seed supply hopper 9 flow down on the flow tray 10 and are fitted into the fitting recesses 16 of the horizontal axle feeding rolls 15. Excess seeds that have not fit in the surrounding fitting recess 16 are returned and leveled by the rotating leveling brush 21, guided downward by the derivative 26, and sown in the pot 2 of the seedling raising container 1.

In this case, the rotation of the motor 67 is transmitted to the output gear 68 → the chain 70 → the intermediate gear 69 (the rotating shaft 74 and the pulley 88) → the rod 73 → the moving shaft 72, and the moving shaft 7
2, the transfer shaft 80 reciprocates back and forth, and the transfer protrusion 81 of the transfer shaft 80 engages with the inner surface of the pot 2 of the seedling raising container 1 and moves forward by one row. On the other hand, by moving the transfer shaft 80 back and forth, the synchronization movement shaft 83 alternately repeats forward rotation and reverse rotation, and the rotation of the synchronization movement shaft 83 causes the intermediate arm 86 to rotate, thereby driving the tip of the intermediate arm 86. The arm 87 is moved back and forth, and the sensor 94 is rotated upward by the seedling raising container 1, the clutch arm 92 is rotated upward, and the driving arm 87 is supported by the support roller 91. The engaging portion 88 at the tip engages with the engaging pin 90 of the disk 89 and pushes forward, thereby rotating the disk 89 to rotate the horizontal axle feeding roll 15 and dropping a row of seeds.

Therefore, the transfer of the seedling growing container 1 by the transfer projection 81 and the rotation of the horizontal shaft feeding roll 15 are synchronized with each other.
When the seedling raising container 1 does not exist, the seeds are not dropped by not supporting the driving arm 87 by the support rollers 91, and also in this point, synchronization is achieved.
The seedling raising container 1 can be detected, and the cost can be reduced. Then
The fitting recesses 16 are not formed at the center portion in accordance with the pot 2 and the flat portion 5 of the seedling raising container 1, and eight fitting recesses for eight lines are provided on the left and right sides except for the flat portion 5. 16a and ten ten-row fitting recesses 16b are formed at equal intervals (FIG. 7), and the number-of-rows changing sheet 17 is shifted to the left and right to fit the eight-row fitting recess 16a with the ten-row fitting. Recess 1
6b is exposed and the other is shielded, so that seeding can be performed on the seedling raising containers 1 having different numbers of rows.

Further, the seed supply hopper 9 is lifted without replacing the horizontal axis feeding roll 15 and the stopper 57
Is removed, then the stopper 52 is removed, and one of the knobs 50 is pulled, so that the entire sheet 17 for changing the number of strips is shifted to one side.
One of the eight-row fitting recess 16a and the ten-row fitting recess 16b is exposed, and the other is shielded. Therefore, the number of articles can be easily changed. Further, since the front end of the sheet 17 for changing the number of rows is fixed to the drifting plate 10 side, and the rear end is positioned on the lower side of the rotation of the rotating leveling brush 21, the seeds are changed. 17 fits only into the fitting recessed portions 16 exposed from the respective windows, and does not fit into the fitting recessed portions 16 shielded by the strip number changing sheet 17.

The sheet 17 for changing the number of strips is made of a synthetic resin or a thin metal plate with elasticity.
Horizontal-axis feeding roll 1 from running grain plate 10 to derivative 26
5 is easy to make close contact with the outer surface, and because it is thin, there is no bad influence on the existence of the supply port 12 and the rotating flat brush 21. Since the shutter 58 is provided on the lower surface side of the flocking board 10 and the discharge receiving trough 64 is provided below the shutter 58, the shutter 58 is provided during the seeding operation.
When the work is retracted and the work is completed, it is moved obliquely downward, the take-out receiving gutter 64 is inserted in this state, and then, when the shutter 58 is opened, the residual seeds fall into the take-out receiving gutter 64 and are collected.

[0023]
