【0001】
【発明の属する技術分野】
本発明は例えば苗載台及び植付爪を備えて連続的に苗植作業を行う田植機にあって、機体にミッドマウント型の施肥機を装備させた施肥機などの農用ホッパ装置に関する。
【0002】
【発明が解決しようとする課題】
施肥機に用いられる肥料ホッパのホッパ蓋は、樹脂製でインジェクション成形により一体形成されている。しかし乍らこのようなインジェクションによる一体形成品の場合、加工コストが高くなるばかりでなく、例えばホッパ内の肥料残量の確認を蓋の外側より可能とすべく透明な合成樹脂製で形成した場合、蓋が強度不足となる不具合がある。
【0003】
【課題を解決するための手段】
請求項1に係る発明は、肥料及び薬剤を貯留するホッパの上方開口部を、ホッパ蓋にて支点ピンを介して開閉自在に閉塞するように構成してなるホッパ装置において、前記ホッパ蓋を中央の中央蓋部材と左右両側の側蓋部材とに分割して形成し、前記中央蓋部材を押出し成形品で、また前記側蓋部材をインジェクション成形品で形成し、前記中央蓋部材下面に左右全幅に亘って遮閉部材を形成し、前記ホッパ蓋を開放させたとき、前記施肥ホッパの上面開口縁に前記遮閉部材のフック形先端が係止し、前記施肥ホッパ内側に中央蓋部材下面側が前記遮閉部材にて連結され、前記施肥ホッパ開口縁と中央蓋部材との隙間が前記遮閉部材にて閉塞されるように構成する一方、前記側蓋部材にボスを一体形成し、該ボスに外側から支点ピンを貫挿し、前記支点ピン先端が前記施肥ホッパの内面側に着脱自在に係止されて、前記ホッパ蓋の両側が前記支点ピンにて施肥ホッパに支持され、前記支点ピンを中心に前記ホッパ蓋が回転して開閉するように構成した。したがって、前記施肥ホッパの一側に起立させるホッパ蓋によって他側から投入する肥料が反対側に飛散するのを防止し、またホッパ蓋に衝突した肥料がホッパ蓋と施肥ホッパ間の隙間から下方に落下するのを防止すると共に、遮閉部材上面に溜った肥料を、ホッパ蓋を閉塞するときに前記施肥ホッパ内部に落下させることが可能になる。施肥作業性と耐久性を向上できる。

BACKGROUND OF THE INVENTION
The present invention relates to an agricultural hopper device such as a fertilizer applicator in which a mid-mount fertilizer is installed in a rice planting machine that includes a seedling stand and a planting claw and performs seedling planting work continuously.
[0002]
[Problems to be solved by the invention]
A hopper lid of a fertilizer hopper used in a fertilizer applicator is made of resin and integrally formed by injection molding. However, in the case of such an integrally formed product by injection, not only does the processing cost increase, but for example, if it is made of a transparent synthetic resin so that the remaining amount of fertilizer in the hopper can be confirmed from the outside of the lid There is a problem that the lid becomes insufficient in strength.
[0003]
[Means for Solving the Problems]
The invention according to claim 1 is a hopper device in which an upper opening of a hopper storing fertilizer and medicine is closed with a hopper lid through a fulcrum pin so as to be opened and closed. The central lid member is divided into left and right side lid members, and the central lid member is formed by extrusion molding, and the side lid member is formed by injection molding product. When the hopper lid is opened and the hopper lid is opened, the hook-shaped tip of the shielding member is locked to the upper opening edge of the fertilizer hopper, and the lower surface side of the central lid member is located inside the fertilizer hopper. A boss is integrally formed on the side lid member, and the boss is integrally formed with the side lid member while the gap between the fertilizer hopper opening edge and the central lid member is closed by the shielding member. Insert the fulcrum pin into the The tip of the fulcrum pin is detachably locked to the inner surface side of the fertilizer hopper, both sides of the hopper lid are supported by the fertilizer hopper by the fulcrum pin, and the hopper lid rotates around the fulcrum pin. It was configured to open and close. Therefore, the hopper lid that stands on one side of the fertilizer hopper prevents the fertilizer thrown from the other side from scattering to the opposite side, and the fertilizer that has collided with the hopper lid moves downward from the gap between the hopper lid and the fertilizer hopper. It is possible to prevent the fertilizer collected on the upper surface of the shielding member from dropping into the fertilizer hopper when the hopper lid is closed. Fertilization workability and durability can be improved.
