Description
【考案の詳細な説明】
本考案は背負動力防除機に於て、薬剤散布噴出用送風機
の空気吸込口を送風機の後方且つエンジンの下方に於で
後向きに開口させることにより作業者の耳に到達する騒
音を低減させようとするものである。[Detailed description of the invention] This invention uses a backpack-powered pest control machine to reach the worker's ears by opening the air inlet of the blower for spraying chemicals backwards at the rear of the blower and below the engine. The aim is to reduce the noise caused by
従来の背負型動力防除機に於では送風機の空気吸込口が
背当側に設けられているため作業者の耳に近く、ファン
の騒音が作業者の耳に到達しやすい欠点があった。In conventional backpack-type powered pest control machines, the air inlet of the blower is located on the back of the worker's back, so it is close to the worker's ears, making it easy for the fan noise to reach the worker's ears.
本考案は上記問題を解決したもので以下図面に関連して
説明する。The present invention solves the above problems and will be described below with reference to the drawings.
1は背負枠、3は背負枠1に取付けた送風機、4は送風
機3に直結したエンジン、2は薬剤タンク、5は燃料タ
ンク、6は背当てある。1 is a back frame, 3 is a blower attached to the back frame 1, 4 is an engine directly connected to the blower 3, 2 is a drug tank, 5 is a fuel tank, and 6 is a back rest.
エンジン4のクランク軸12にはファン7が固定され、
ファンケース前壁13の中央にあけた風入口9には偏平
なダクト8がボルトにより固定されている。A fan 7 is fixed to the crankshaft 12 of the engine 4,
A flat duct 8 is fixed with bolts to an air inlet 9 formed in the center of the front wall 13 of the fan case.
ダクト8は背当6とファンケース前壁13の間を下降し
、後向きに湾曲してファンケースの下を通り、ファンケ
ースの後部且つエンジン4の下部に於て後方に向け開口
し、空気吸込口10を形威している。The duct 8 descends between the backrest 6 and the front wall 13 of the fan case, curves backward, passes under the fan case, opens rearward at the rear of the fan case and below the engine 4, and inhales air. He has an impressive mouth.
エンジン4を起動しファン7を駆動すると、ファン7の
回転により空気は空気吸込口10から矢印のように吸入
され、風入口9を経てファン7により加圧され、薬剤散
布噴出用の風力となる。When the engine 4 is started and the fan 7 is driven, air is sucked in from the air suction port 10 as shown by the arrow due to the rotation of the fan 7, passes through the air inlet 9, is pressurized by the fan 7, and becomes wind force for spraying and spraying the medicine. .
ファン7で加圧された空気の一部は、窓孔18を経てエ
ンジン4のシリンダ15を冷却した後、風吐出口16か
ら大気中に放出される。A part of the air pressurized by the fan 7 passes through the window hole 18 to cool the cylinder 15 of the engine 4, and then is discharged into the atmosphere from the wind outlet 16.
このように本考案によると空気吸込口10を作業者の耳
の位置Eから最も遠い送風機3の後側下部に開口させた
ので、作業者が感じるファン騒音を大巾に低下させるこ
とが出来る。As described above, according to the present invention, since the air suction port 10 is opened at the lower rear side of the blower 3 farthest from the worker's ear position E, the fan noise felt by the worker can be significantly reduced.
又送風機3とエンジン4は共に防音壁の機能を果し、そ
の意味からも騒音による疲労を防止することが出来る。Further, both the blower 3 and the engine 4 function as a soundproof wall, and in this sense, fatigue caused by noise can be prevented.
図面は本考案実施例の要部縦断側面図である。
