Then, it is configured to control to spray from the medicine spraying port 17 to the seedling on the seedling stage mat.

次に、前記施肥装置の別実施例について説明する。
図4〜図6に示すように、施肥ホッパ40,40を各2条づつの左右に配設し、両ホッパ40,40間に所定の空間ができる構成のものにおいて、上記空間が上から見て埋まるように左右のホッパの蓋板40a,40aが機体の中央側に向かって横方向に開くようにする(図5)。また、図7〜図9に示すように、左右のホッパの間隔があまり広くない場合は、各ホッパの蓋板が左右に分かれて開くようにする(図8)。蓋板が開く位置は、機体の中央までになるようワイヤーや金具等で規制する。
Next, another embodiment of the fertilizer application will be described.
As shown in FIGS. 4 to 6, the fertilizer hoppers 40, 40 are arranged on the left and right sides of each two strips, and a predetermined space is formed between the hoppers 40, 40. The lid plates 40a, 40a of the left and right hoppers are opened laterally toward the center side of the machine body (FIG. 5). Moreover, as shown in FIGS. 7-9, when the space | interval of the left and right hoppers is not so wide, the cover plate of each hopper is divided and opened so as to be divided into left and right (FIG. 8). The position where the cover plate opens is restricted by wires, metal fittings, etc. so that it reaches the center of the fuselage.

蓋板を機体中央側に向かって横方向に開くようにし、左右ホッパ間の空間を埋めることにより、肥料袋から肥料が出るのを止めることなく左右のホッパに肥料を連続的に供給することができる。また、各ホッパの蓋板が左右に分かれて開くようにすることにより、蓋板を開いた際に蓋板の最高点が低くなって肥料が入り易くなる。蓋板上にこぼれた肥料は蓋板を閉める方向に回動させることで、肥料は蓋板上を流下しホッパ内に流入されることになる。   By opening the lid plate laterally toward the center of the aircraft and filling the space between the left and right hoppers, fertilizer can be continuously supplied to the left and right hoppers without stopping the fertilizer from coming out of the fertilizer bags. it can. Moreover, when the cover plate of each hopper is divided and opened to the left and right, when the cover plate is opened, the highest point of the cover plate is lowered and the fertilizer is easily entered. The fertilizer spilled on the cover plate is rotated in the direction of closing the cover plate, so that the fertilizer flows down on the cover plate and flows into the hopper.

また、図10及び図11に示す実施例では、左右のホッパ間の空間を埋めるように、機体中央までの長さを有する受板40b,40bをホッパ40と蓋板40aとに取り付け、受板40bを広げた際に機体の中央側が高くなるよう傾斜状態に規制保持することで、受板40bの上にこぼれた肥料がホッパに向かって自然流下するようにしている。なお、この受板40bには衝立板40cが設けられ、肥料の飛散を防止するようにしている。   In the embodiment shown in FIGS. 10 and 11, receiving plates 40b and 40b having a length up to the center of the machine body are attached to the hopper 40 and the cover plate 40a so as to fill the space between the left and right hoppers. By restricting and holding in an inclined state so that the center side of the airframe becomes higher when the 40b is spread, the fertilizer spilled on the receiving plate 40b naturally flows down toward the hopper. The receiving plate 40b is provided with a partition plate 40c to prevent the fertilizer from scattering.

図12〜図14に示す実施例は、ゴム材からなる円筒状のエアチャンバ44において、該エアチャンバの繰出ロート42への連通口部50付近における内部に、円筒状の補強プレート51と補強棒材52,52を設けた構成である。従来では連通口部の繰出ロートへの差し込み時に、エアチャンバがゴム材のため変形し、差し込み、取り付けに手間取る問題があったが、本例では上記のような補強プレート51と連通口部の差込み方向両側に設けられた補強棒材52とによって変形を防ぐことができ、連通口部の向かい側から押し込むことができるので、清掃等で取り外しても容易に取り付けることができる。   In the embodiment shown in FIGS. 12 to 14, in a cylindrical air chamber 44 made of a rubber material, a cylindrical reinforcing plate 51 and a reinforcing rod are provided in the vicinity of the communication port 50 to the feeding funnel 42 of the air chamber. In this configuration, the materials 52 and 52 are provided. Conventionally, when the communication port portion is inserted into the feeding funnel, the air chamber is deformed due to the rubber material, and there is a problem that it takes time to insert and attach. However, in this example, the reinforcement plate 51 and the communication port portion are inserted as described above. Deformation can be prevented by the reinforcing bar members 52 provided on both sides in the direction, and it can be pushed in from the opposite side of the communication port, so that it can be easily attached even if it is removed by cleaning or the like.

図15に示すように、左右各2条で計4条の施肥装置5,5…を一箇所で駆動するための左右方向に長い施肥伝動軸53が架設されている。この施肥伝動軸53は、これの往復回動により適宜の連動機構を介して肥料繰出部41の繰出ロールを間欠的に回転させるようになっている。本例では、この施肥伝動軸53に各繰出ロート42,42…を貫通軸架させると共に、これら各繰出ロートが図16に示すように、上部の肥料繰出部41に対して施肥伝動軸53を回動支点として揺動開閉するように構成している。これによれば、繰出ロートの繰出部に対する固定具を減らすことができるばかりでなく、着脱に対する作業性が向上することになる。   As shown in FIG. 15, a fertilization transmission shaft 53 that is long in the left-right direction for driving a total of four fertilizers 5, 5... The fertilizer transmission shaft 53 is configured to intermittently rotate the feeding roll of the fertilizer feeding portion 41 through an appropriate interlocking mechanism by reciprocating rotation of the fertilizer transmission shaft 53. In this example, each feeding funnel 42, 42... Is pivoted through the fertilizer transmission shaft 53, and as shown in FIG. 16, the feeding funnel 53 is applied to the upper fertilizer feeding portion 41. It is configured to swing open and close as a pivot point. According to this, not only can the number of fixtures for the feeding portion of the feeding funnel be reduced, but also the workability for attachment / detachment is improved.

また、図17に示すように、施肥装置を駆動する施肥伝動軸53と植付クラッチケース54とを結ぶロッドを上下方向と左右横方向の二本のロッド55,56にて駆動するように連動構成する。上下方向の縦ロッド55は施肥伝動軸53の駆動アーム57に連結し、横方向の横ロッド56は植付クラッチケース54の駆動クランクアーム58に連結している。そして、横ロッド56の途中部には、フレーム59にスライド可能に架設した支軸60回りに回動自在なレバー61付支点移動調節部材62を設けた構成としている。レバー61によって支点移動調節部材62を、図19(a)のように、左側に移動調節すると、横ロッド56の揺動ストロークが小さくなり、繰出量は少なくなる。また、図19(b)のように、右側に移動調節すると、横ロッド56の揺動ストロークが大きくなって繰出量は多くなる。   Further, as shown in FIG. 17, the rod connecting the fertilizer transmission shaft 53 and the planting clutch case 54 for driving the fertilizer is interlocked so as to be driven by the two rods 55 and 56 in the vertical direction and the horizontal direction. Constitute. The vertical rod 55 in the vertical direction is connected to the drive arm 57 of the fertilizer transmission shaft 53, and the horizontal rod 56 in the horizontal direction is connected to the drive crank arm 58 of the planting clutch case 54. A fulcrum movement adjusting member 62 with a lever 61 that is rotatable around a support shaft 60 slidably mounted on a frame 59 is provided in the middle portion of the horizontal rod 56. When the fulcrum movement adjusting member 62 is moved and adjusted to the left side by the lever 61 as shown in FIG. 19A, the swing stroke of the horizontal rod 56 is reduced and the feeding amount is reduced. Further, as shown in FIG. 19B, when the movement is adjusted to the right side, the swing stroke of the horizontal rod 56 is increased and the feeding amount is increased.

ロッドを二本に分け、2段階で構成することにより、ロッドが斜めになりすぎることを防ぐことができる。横ロッドの支点位置を左右に移動調節することによって、横ロッドの揺動ストロークを変更し、肥料繰出部の繰出量を任意に調節することができる。   By dividing the rod into two parts and configuring the rod in two stages, it is possible to prevent the rod from becoming too oblique. By moving and adjusting the fulcrum position of the horizontal rod to the left and right, the swing stroke of the horizontal rod can be changed and the feed amount of the fertilizer feed portion can be arbitrarily adjusted.
