【考案の詳細な説明】
(イ) 産業上の利用分野
本考案は種子又は粒状肥料等の粒状物を圃場に
播種又は施肥する農用粒状物繰出装置に関する。[Detailed description of the invention] (a) Industrial application field The present invention relates to an agricultural granular material dispensing device for sowing or fertilizing a field with granular materials such as seeds or granular fertilizers.

られている。(b) Prior art Conventionally, a seeding machine or a fertilizer applicator has a plurality of tank sections arranged in a horizontal direction, and feeds out granular materials such as seeds or granular fertilizers in the tank sections with a large number of feed rolls to sow or fertilize a field. Agricultural granule dispensing devices such as the above are already known.

又は施肥を行なうことができなかつた。(c) Problems to be solved by the invention In the known agricultural granular material dispensing device, when the dispensing device vibrates during operation due to vibrations of the engine or irregularities in the field, the tank part and the tank part located away from the central transmission case and The pay-out rolls vibrated more than their neighbors, causing the outer pay-out rolls to pay out more particulate matter than the inner pay-out rolls, making it impossible to achieve uniform seeding or fertilization.

定になるようにして前述の問題点を解決した。(d) Means for solving the problem The present invention has a plurality of tank parts arranged in a row in the horizontal direction, a large number of feeding rolls are provided at the bottom of these, and these feeding rolls are extended from the transmission case to both sides. By attaching it to the drive shaft and providing a large number of feeding grooves on the outer periphery of these feeding rolls, and making the granular material feeding volume of the feeding rolls located on the outside smaller than the feeding volume of the feeding rolls located on the inside, The above-mentioned problem is solved by making the amount of feed of each feed roll approximately constant even if the amplitude of the tank portion and the feed roll is larger than the amplitude of the one closer to the center.
(ホ) 作用
作業中各繰出ロールを回転駆動して機体を前進

粒状肥料を繰出し、繰出された粒状物は圃場に播
種又は施肥される。(E) Function When the machine is moved forward by rotationally driving each feed roll during work, each feed roll feeds out seeds or granular fertilizer in the tank, and the fed granules are sown or fertilized in the field.
このような作業中、タンク部及び繰出ロールが
エンジンの振動、又は圃場の凹凸により振動した

る。 During such work, when the tank section and the feed roll vibrate due to engine vibrations or unevenness in the field, the amplitude gradually increases as you move away from the center, but it is possible to increase the payout volume of the feed roll itself outward. Since the position of the roll is set to be smaller, the increase in the amount of feed due to vibration is offset, and as a result, the amount of feed of each feed roll becomes approximately uniform.

The feed rolls 10a, 10b... rotate to fill each groove 12.
The granules that have entered the ..., 12a... are fed out, and are sown or fertilized into the field via the conduit 17....

The density of the particulate matter entering the grooves 12..., 12a... is greater than the density of the particulate matter entering the grooves 12..., 12a... of the inner feeding roll 10b....
しかし、溝１２…、１２ａ…の容積は内側のも
のより外側のものが小になつているので、実質的
な繰出量が略同一になる。 However, since the volumes of the outer grooves 12..., 12a... are smaller than those on the inner side, the actual amount of delivery is approximately the same.
更に別の例を第６〜７図について説明すると、

が略同一になる。 Another example will be explained with reference to FIGS. 6 and 7.
In this example, the feeding volume of each feeding roll 10a, 10b... is set to be the same, but the bottom plate 9 of the funnel portion 9...
Since the inclination angle of a is set so that the outer one θ 1 is smaller than the inner one θ 2 , the inclination angle θ 1 of the outer bottom plate 9a is smaller than the angle of repose of the granules, so that the granules do not fall into the Stacked on the bottom plate and fed out roll 10
The inflow into a, 10b, .

ことがない。 Figures 8 and 9 show the marker 18, and the conventional marker 18' is transparent so that granules can be seen through when the lever 19 is operated to raise it as shown by the chain line in Figure 9. Since the marker 18' is located directly above the tank section 8, which is made up of a body, the mud adhering to the marker 18' falls onto the tank section 8, making it impossible to see through it. Since the middle of the rod part is bent so as to be deviated to the side of the tank part 8 as shown, and to the front as shown in Figs. 1 and 9 when viewed from the side, the marker 18 is inactive. When raised to the posture, mud falling from the marker 18 does not adhere to the tank part 8.

減収となることを未然に防止することができる。(g) Effects of the invention As described above, the present invention has a plurality of tank parts 8... arranged in a row in the horizontal direction, a large number of delivery rolls 10a, 10b... provided below them, and the delivery rolls 1 of these delivery rolls 10a, 10b...
0a, 10b... are attached to the drive shaft 11 extending from the transmission case 4 to both sides, and a large number of grooves 12... are provided on the outer periphery of the delivery rolls 10a, 10b..., and the granular materials of the delivery rolls 10a... located on the outside are provided. The feeding roll 10b whose feeding volume is located inside...
Since the payout volume is smaller than that of the tank part 8, when the vibration of the engine 2 and the shaking of the machine body 1 due to unevenness of the tiller spread to each tank part 8, the effect on the outer tank part 8 is amplified more than that of the inner part. However, by making the delivery volume of the outer delivery part smaller than the delivery volume of the inner delivery part, the delivery amount of each delivery part becomes approximately uniform, resulting in a shortage of seeds or granular fertilizer in some parts. This prevents a decrease in yield due to a shortage of crops or fertilizer.
