１３６１１１号公報により公知である。(Prior art) Conventionally, a horizontal axis feeding roll having a feeding recess is provided, and above the horizontal axis feeding roll there is a roller whose axial direction is parallel to the axis direction of the horizontal axis heavy eel roll and whose contact surface is the same as that of the horizontal axis feeding roll. A seeding device for seedling boxes equipped with a rotating brush that rotates in different directions was developed in 1982.
It is known from the publication No. 136111.
（発明が解決しようとする問題点）
前記公知の、回転ブラシは横軸繰出ロールに対する接触
度合により播種量が調節されるが、その調節は、目盛を
付けてもできなかった。(Problems to be Solved by the Invention) The amount of seeds sown in the known rotary brush is adjusted by the degree of contact with the horizontal feed roll, but this adjustment could not be made even with a scale.
たとえば、ミリメートルの紙入を貼っても、最終は目見
当になるので、１０分の１ＩＩ１１の誤差なく調節する
ことは困難で、左右の播種量が少し狂ってくる。ノギス
のような、紙入を貼れば、左右均等調節も可能であるか
もしれないが、そのようなものでなく、もっと、簡単な
構造で。For example, even if you paste a millimeter paper container, the final result is a rough estimate, so it is difficult to adjust without an error of 1/10, and the amount of sowing on the left and right ends up being a little off. It might be possible to adjust the left and right sides evenly by attaching a piece of paper like a caliper, but it's not something like that, it's a simpler structure.
精度が高く、左右均等播種調節が出来ないものかと、鋭
意工夫したのが本願である。The present application was developed with the aim of achieving high accuracy and making it possible to adjust the sowing evenly on the left and right sides.
そこで、大小２個の丸穴の「ずれ」による寸法確認の手
段を開発したものである。たとえば、２＋ａｍの丸穴と

ｌ＋ａ＋の丸穴を正確に合せることは、１ｍｍの丸穴に
棒を突っ込んで操作すると訳なく出来る。また、中心を
合せることも訳なく出来るということである。Therefore, we have developed a means of checking dimensions by checking the "shift" of two large and small round holes. For example, if the round hole of 2+am and the round hole of . Also, it is possible to align the centers without any reason.

Another adjustment circular hole 71' having the same diameter as that of the side plate 21 is formed.
The through hole η′ formed in is formed to have a smaller diameter than the through hole π,
The gap between the adjustment circular hole 71' and the through hole η° is formed to [■], and as shown in FIG. 8, by overlapping the adjustment circular hole 71' and the through hole 72', 9 and the seeding amount adjustment rotary brush 16 is configured so that the gap is [l],
The height can be adjusted in two levels.

量調節回転ブラシ１６との隙間冗の幅を調節できる。In this case, the seeding rate adjusting rotary brush 16 has both left and right ends of the central axis n pivoted to a movable adjusting slope of the height adjusting device, and the movable adjusting slope has its upper part attached to the side plate 21 with bolts 24 so that it can move up and down. Since the bent portion π of the lower part is engaged with the elongated hole 74 formed in the side plate 21, when the bolt 24 is loosened and the adjustment plate n is moved up and down, the horizontal shaft feeding roll 9 and the seeding amount adjustment rotation are made. The width of the gap with the brush 16 can be adjusted.

なり、横軸繰出ロール９と播種量調節回転ブラシ１６と
の隙間７６も０．５ｓｍとなる（第１Ｏ図）。Therefore, the adjustment circular hole 71 is formed in the movement adjustment ramp of the height adjustment device W70, and the through hole η, which is formed in the side plate 21 with a smaller diameter than the adjustment circular hole 71, is formed on the left and right sides. When the lower end of the inner circumferential surface of the adjusting circular hole 71 of the adjusting slope is overlapped so as to coincide with the lower end of the inner circumferential surface of the through hole η (FIG. 7),
This means that the seeding amount adjusting rotary brush 16 has moved up by 0.5 m, and the gap 76 between the horizontal axis feed-out roll 9 and the seeding amount adjusting rotating brush 16 also becomes 0.5 sm (Fig. 1O).

にＥ動させることができる。Therefore, when a rod with the same diameter is inserted into the through hole η and the left and right adjustment plates n are moved upward, the adjustment circular hole 71 is formed on the lower surface of the rod.
Since the lower surfaces are in contact with each other, the lower end of the inner peripheral surface of the adjustment circular hole 71 can be aligned with the lower end of the inner peripheral surface of the through hole η, allowing accurate sowing even with a width as small as 0.5 m. The quantity adjusting rotary brush 16 can be moved completely horizontally with respect to the horizontal axis feeding roll 9.

することができる。When the gap between the seed amount adjustment rotary brush 16 and the outer circumferential surface of the horizontal feed roll 9 becomes large, the seed rice that was fitted in the feed recess 10 in a substantially horizontal state as shown in FIG. 69
As shown in FIG.
Since it is fitted inside, the amount of sowing can be adjusted over a wide range by adjusting the rotation speed of the variable speed motor with the adjustment knob 55.

6 is also uniform, and the amount of seeding can be adjusted accurately.
