【考案の詳細な説明】
機体最後尾に軸流送風機の吸気口を有する一般
的なスピードスプレーヤにおいては、散布用噴気
の整流の為にフアンの風下側にある程度の長さの
整流用風胴が必要であり、この為にフアンと駆動
用エンジンとの間に長大なフアン軸が必要とな
る。[Detailed explanation of the invention] In a typical speed sprayer that has an axial blower inlet at the rear of the machine, a rectifying wind barrel of a certain length is installed on the leeward side of the fan to rectify the spray jet. Therefore, a long fan shaft is required between the fan and the driving engine.
一方、最近経済性の面から駆動用エンジンとし
てデイーゼルエンジンが多用される様になつた
が、デイーゼルエンジンは一般にガソリンエンジ
ンに比して振動やトルク変動が大きい。 On the other hand, diesel engines have recently come into widespread use as driving engines due to economic considerations, but diesel engines generally have greater vibration and torque fluctuations than gasoline engines.
したがつて、前述の如きスピードスプレーヤの
比較的長大なフアン軸を駆動用エンジンとしての
デイーゼルエンジンの出力軸に片持梁状で直接固
着せしめた場合には、作業中フアン軸はきわめて
苛酷な条件下にさらされることとなりはなはだし
い場合には、フアン軸の折損事故をもひきおこし
かねない。 Therefore, when the relatively long fan shaft of a speed sprayer as described above is fixed directly to the output shaft of a diesel engine as a driving engine in a cantilevered manner, the fan shaft is subjected to extremely harsh conditions during work. If the fan shaft is exposed to the ground for a long time, it may cause an accident with the fan shaft breaking.
本考案は上記に鑑み、エンジン出力軸とフアン
軸との間に緩衝カツプリングを介在せしめるとと
もに、フアン軸をエンジンに固着した外筐内に軸
支することにより、安全に作業の出来るスピード
スプレーヤを提供せんとするものである。 In view of the above, the present invention provides a speed sprayer that can be operated safely by interposing a buffer coupling between the engine output shaft and the fan shaft, and by supporting the fan shaft within an outer casing fixed to the engine. This is what I am trying to do.

They are arranged in the order of 11. The engine 10 is a diesel,
This invention is particularly effective in the case of a diesel engine, regardless of whether it is a gasoline engine or one that can be used both for running and driving auxiliary equipment.

グ１７を介装せしめる。 The blower 11 has a rectifying wind body 9, and a rectifying body 14 having a diameter corresponding to the size of the boss portion of the fan 19 is fixed to the center of the inside of the wind body 9 via a support plate 18. At the center of the rectifying body 14, an outer casing 30 is disposed, to which bearings 20, 21 are fixed, a fan shaft 15 is rotatably supported, and one end is fixed to the engine 10. On the other hand, the front end of the fan shaft 15 and the output shaft 1 of the engine 10
A flange member 2 is attached to each of the opposite shaft ends of 6.
4 and 25 are fixed together, and a buffer coupling 17 is interposed between them.
