(Operation) Next, the operation will be described.

The supply hopper 7 is filled with the granular medicine 29, and the adjusting screw 3
3 is appropriately rotated to adjust the adjusting rod 32 in the direction of arrow B to adjust the distance between the tip of the adjusting brush 34 and the outer peripheral surface of the horizontal shaft driving roll 9, and the adjusting rod 22 is lifted up and engaged. The groove 23 is selectively engaged with the engaging portion 24, and the position and angle of the comb teeth 25 are adjusted according to the growing degree of the seedlings 5 of the seedling raising box 3 to be inserted into the transfer table 1.

Next, when the switch of the motor is turned on, the transfer roll 2 and the horizontal-axis feeding roll 9 rotate together, and the horizontal-axis feeding roll 9
According to the rotation of, the horizontal shaft feeding roll 9 and the feeding groove 10 are both rotated by the belt 15 wound around the pulley 16 and the pulley 17. Therefore, when the seedling raising box 3 after raising seedlings is placed on the upper surface of the transfer roll 2, the seedling raising box 3 moves the lower part of the comb teeth 25 in the direction of arrow A, and the comb teeth 25 move the seedlings 5 as shown in FIG. Weed backward and expose the soil 4.

Then, by the rotation of the horizontal axis feeding roll 9, the feeding groove 10
The medicine 29 engaged with is gradually fed out in a horizontal line, but the discharge port 31 of the diffusion device 11 below it is provided with a chevron partition 35.
Since it is divided into several parts in the left-right direction by the horizontal groove, even if it is fed from the groove 10 to the horizontal line, it is evenly divided into several parts in the lateral direction by the chevron partitioning body 35 and is evenly supplied to the base of the nursery box 3. To be done.

Then, the medicine 29 attached to the outer peripheral surface of the horizontal axis feeding roll 9 and co-rotating is scraped off by the rotary brush 14 provided on the side portion of the horizontal axis feeding roll 9, but the rotary brush 14 is adjusted by the adjusting wheel 16. , Belt 1 hung around the wheel 17
5 in the same direction as the horizontal axis feeding roll 9 (the contact part is in the opposite direction)
Since it is rotating to the left, the medicine 29 is scraped off, and the medicine 29 slides down on the comb tooth 26 of the comb comb tooth body 26 of the grass body 19.

Then, the comb teeth 25 act as weeding the seedlings 5 as shown in FIG. 1, and the discharge port 31 has the comb teeth 25.
Due to the fact that the seedling 5 is provided directly above, the granular chemical agent 29 is not applied to the leaves of the seedling 5 and can be sprayed on the exposed soil floor 4.

(Effect) None of the above-mentioned publicly known examples describes the diffusion device of the present invention having the chevron partitions at predetermined intervals in the left-right direction to disperse the granular drug on the left-right side. The delivered product has a structure in which it is dropped as it is. Therefore, they cannot be evenly distributed in the width direction.

However, according to the present invention, since the granular medicine fed by the horizontal axis feeding roll 9 is evenly dispersed on the left and right sides by the chevron partitions 35 provided at predetermined intervals in the left and right direction, the granular medicine is diffused. The granular drug that is evenly dispersed on the left and right by the device 11 is the diffusion device 1
Since the roots are exposed by the grass bodies 19 having the comb teeth 25 that expose the roots of the seedlings 5 by rubbing the seedlings 5 provided in front of the roots 1, there is an effect that the roots are reliably supplied to the roots.
