(effect) Next, we will discuss the effect.

The present invention has the above-mentioned configuration, in which the seed rice is fed into the seed rice supply hopper 2, the seedling raising boxes are transferred by the transfer table 56, and the variable speed motor 27 of the seed rice supply device 1 is
When turned on, the rotation of the variable speed motor 27 causes the horizontal shaft feeding roll 9, the first rotating leveling brush 19,
The second rotating leveling brushes 17 are respectively rotated.

The seed rice in the seed rice supply hopper 2 flows down on the flow shell plate 4 and reaches the seed rice supply section 18, where it is transferred to the horizontal axis feed-out roll 9.
Most of the excess seed rice that is not fitted into the feeding recess 10 that fits into the feeding recess 10 and rises by the rotation of the horizontal axis feeding roll 9 and rotates together with the horizontal axis feeding roll 9 is transferred to the first rotational leveling. Seed supply section 1 by brush 19
8 and leveled, and the first rotating leveling brush 19
The seed rice that has not fit into the feeding recess 10 that has passed below is returned and leveled by the second rotating leveling brush 17, and is fitted into the feeding recess 10 that has passed below the second rotating leveling brush 17. The seed rice is guided by the seed guidance cover 73, rotates together with the horizontal axis pay-out roll 9, reaches below the horizontal axis pay-out roll 9, falls under its own weight into the seedling box being transferred by the transfer table 56, and is sown. be done.

In this case, due to differences in the type and size of rice seeds, or when changing the amount of sowing, etc., the outer circumferential surface of the horizontal shaft feeding roll 9, the brush 8, the rotating leveling brush 17, the seed guiding cover 73, Although it is necessary to adjust the positional relationship with the strip spreading body 70, the present invention allows the brush 8 etc. and the horizontal shaft feeding roll 9 to be adjusted.
Transparent window holes 77, 78, 7 are provided in the side plate 21 of the rice seed supply device 1 at positions where the positional relationship with the outer peripheral surface of the rice seed supply device 1 can be visually confirmed.
9 and 80, the brush 8, the rotary leveling brush 17, and the seed guide cover 73
are the leveling brush viewing window holes 77 on the left and right side plates 21.
The rotary leveling brush see-through window 78 and the seed rice guidance cover see-through windows 79 and 80 allow accurate adjustment while viewing from the left and right sides.

Therefore, it is possible to easily and accurately adjust in advance without operating the seed rice supply device 1.

Further, the width of the horizontal axis feeding roll 9, the leveling brush 8, the rotary leveling brush 17, and the seed paddy guiding cover 73 is formed to be larger than the horizontal width of the supply port 5 of the supply hopper 2 and the width of the feeding recess 10. Therefore, the seed rice will not leak through the viewing windows 77, 78, 79, and 80.

(Effects) The present invention consists of a supply hopper 2, a horizontal axis feeding roll 9, a leveling brush 8 provided on the rotation rising side 11 of the horizontal axis feeding roll 9, and a rotation leveling brush 8 provided on the upper part of the horizontal axis feeding roll 9. In the one having a flat brush 17 and a seed guide cover 73 provided on the rotating downward side 13 of the horizontal axis feeding roll 9, the horizontal axis feeding roll 9, the leveling brush 8, and the rotational leveling are more closely connected than the supply hopper 2. The flat brush 17 and the rice seed guide cover 73 are formed to have a large width, and the left and right side plates 21 have a window hole 77 for seeing through the leveling brush, a window hole 78 for seeing through the rotating leveling brush, and a window hole 78 for seeing through the seed rice guiding cover. Window holes 79, 80
The brush 8, the rotary leveling brush 17, and the seed guide cover 73 are connected to the leveling brush viewing window hole 77 of the left and right side plates 21, Leveling brush transparent window hole 78 and seed guide cover transparent window hole 7
9 and 80, accurate adjustment can be made while viewing from the left and right sides.

The horizontal axis feeding roll 9 is lower than the supply hopper 2.
and the leveling brush 8 and the rotating leveling brush 17.
Since the seed rice guiding cover 73 is formed with a large width, the viewing window holes 77, 78, 79,
From 80, the seed rice will not leak.

This effect is achieved.
