次に前述の粉体散布車による粉体散布動作を説明する。Next, the powder spraying operation by the above-mentioned powder spraying vehicle will be described.
モータ19を駆動してベルト９を回転すると、ベルト９上
の粉体を排出ダクト15に向けて搬送して落下排出できる
ので、粉体タンク４内の粉体量に関係なく常に一定量の
粉体を連続して落下排出できる。When the motor 19 is driven and the belt 9 is rotated, the powder on the belt 9 can be conveyed toward the discharge duct 15 and dropped and discharged. Therefore, regardless of the amount of powder in the powder tank 4, a constant amount of powder is always supplied. The body can be continuously dropped and discharged.
また、ベルト９は駆動ローラ６の大径ローラ6aと支持ロ
ーラ７と従動ローラ８の大径ローラ8aで支持されながら
回転するので、粉体の重量でベルト９がたわむことがな
い。Further, since the belt 9 rotates while being supported by the large-diameter roller 6a of the driving roller 6, the supporting roller 7, and the large-diameter roller 8a of the driven roller 8, the belt 9 does not bend due to the weight of the powder.
また、粉体タンク４内の粉体はベルト９の回転によって
後壁4b側に押されるが、複数の減圧板11にそれぞれ押し
つけられるので、粉体の圧密が緩和されてゲート30から
の排出量を安定化できると共に、粉体タンク４内で粉体
が架橋現象を起すことがない。Further, the powder in the powder tank 4 is pushed toward the rear wall 4b by the rotation of the belt 9, but the powder is pressed against the plurality of pressure reducing plates 11, so that the compaction of the powder is alleviated and the discharge amount from the gate 30 is reduced. And the powder does not cause a crosslinking phenomenon in the powder tank 4.
また、ゲート30の上方に設けた崩落防止板13によってゲ
ート30付近で粉体タンク４内の粉体が崩落することを防
止でき、ゲート30から排出される粉体量が一時的に増加
することがない。Further, the fall prevention plate 13 provided above the gate 30 can prevent the powder in the powder tank 4 from falling near the gate 30, and the amount of powder discharged from the gate 30 can be temporarily increased. There is no.
また、第１・第２・第３シリンダー34,35,36で第１・第
２・第３ゲート31,32,33を上下動して開閉できるので、
ベルト９の幅方向の一側、中央、外側のいずれか１つ、
または複数より粉体を排出ダクト15の入口側に搬送して
排出できるから、粉体の散布幅を任意に変更できる。Also, since the first, second, and third cylinders 34, 35, and 36 can be vertically moved to open and close the first, second, and third gates 31, 32, and 33,
One of the width direction one side, the center, and the outside of the belt 9,
Alternatively, a plurality of powders can be conveyed to the inlet side of the discharge duct 15 and discharged, so that the distribution width of the powders can be arbitrarily changed.
粉体タンク４内の粉体はベルトコンベア10上に落下し、
ベルトコンベア10の回転によって搬送されて排出ダクト
15より落下排出されるので、粉体タンク４内の粉体量に
関係なく一定量の粉体を排出ダクト15に搬送して常に一
定量の粉体を散布できる。The powder in the powder tank 4 falls onto the belt conveyor 10,
Exhaust duct conveyed by rotation of belt conveyor 10
Since it is dropped and discharged from 15, the fixed amount of the powder can be conveyed to the discharge duct 15 regardless of the amount of the powder in the powder tank 4, and the fixed amount of the powder can be always sprayed.
任意のゲートを閉じ位置とし、残りのゲートを開き位置
とすれば、ベルトコンベア10の幅方向の一部分より排出
ダクト15に粉体を搬送できるので、粉体の散布幅を任意
に設定したり有効散布幅の一側、他側、中央や一側と中
央、他側と中央、一側と他側などにより粉体を散布でき
る。If you set the gates to the closed position and the remaining gates to the open position, the powder can be conveyed to the discharge duct 15 from a part of the belt conveyor 10 in the width direction. The powder can be sprayed on one side, the other side, the center, the one side and the center, the other side and the center, the one side and the other side of the spraying width.
したがって、散布ミス等により散布幅方向の一部分に散
布した粉体量が少ない場合には、その少ない部分にのみ
再度粉体を散布できると共に、地盤の形状等に応じて散
布幅方向の粉体量を異ならせることができる。Therefore, if the amount of powder that has been applied to a part in the spray width direction is small due to a spraying error, etc., the powder can be sprayed again only to that small part, and the amount of powder in the spray width direction can be changed depending on the shape of the ground. Can be different.
また、粉体タンク４内に設けた減圧板11によって粉体の
圧密を緩和してゲート30からの排出量を安定化できると
共に、粉体タンク４内で粉体が架橋現象を起すことがな
い。Further, the pressure reducing plate 11 provided in the powder tank 4 can alleviate the compaction of the powder to stabilize the discharge amount from the gate 30, and the powder does not cause a crosslinking phenomenon in the powder tank 4. .
