Description

【0001】
【発明の属する技術分野】
この発明は、薬液散布機等に装備されるホース巻取り装置に係り、詳しくは、ホースをホースリールに巻取る際に、整列巻きのために手動でホースガイド部を変位操作するホース巻取り装置に関するものである。
【0002】
【従来の技術】
図7は従来の動力噴霧機セット84の斜視図、図8は図7の整列巻きレバー85の斜視図である。後述のこの発明の実施の形態としての動力噴霧機セット10と同一の部分は、同符合で指示して、説明は省略し、主要点についてのみ説明する。整列巻きレバー85は、上端から少し下の位置においてホースガイド部47を有している。ステー87は、フレーム25の下辺部に固定され、整列巻きレバー85の下端部の板部88は、支軸ピン89によりステー87の突出端部に、ホースリール30の軸方向に対して直角の水平線の周りに回転自在に支持されている。支軸ピン89の周りの整列巻きレバー85の揺動により、ホースガイド部47はホースリール30の軸方向へ往復動する。一方、クラッチハンドル86は、基端側をアーム対34の外側アームに固定され、アーム対34と一体揺動する。クラッチハンドル86を引張ばね36の引張力に抗して下方へ傾動したときは、テンションプーリ35がベルト33の緊張力を解除し、ベルト33によるエンジン動力のプーリ31からプーリ32への伝達を断にする。クラッチハンドル86を上方へ起こすと、クラッチハンドル86は、引張ばね36の引張力により上方へ傾動し、テンションプーリ35がベルト33に大きな力で押し付けられて、ベルト33は緊張状態になり、ベルト33によるエンジン動力のプーリ31からプーリ32への伝達を接にして、ホースリール30はホース15の巻取り方向へ回転駆動される。
【0003】
【発明が解決しようとする課題】
薬液散布作業では、通常、作業者が二人いて、一方の作業者は、ホース15の先端で噴霧ノズルを操作し、他方の作業者は、動力噴霧機セット84の所で、待機し、ホース15を巻取るときに、整列巻きレバー85及びクラッチハンドル86を操作するようになっている。従来の動力噴霧機セット84では、動力噴霧機セット84側に待機する作業者は、ホース15の巻取り時では、噴霧ノズル側の作業者に注意を払いつつ、整列巻きレバー85及びクラッチハンドル86を左右の手で把持して、操作する必要がある。したがって、煩雑であるとともに、両手がふさがっているので、ホース15がホースリール30から逸脱しそうになったり、動力噴霧機セット84の部位に絡みそうになっても、迅速に対処できなかった。
【0004】
この発明の目的は、上述の問題点を克服できるホース巻取り装置を提供することである。
【0005】
【課題を解決するための手段】
この発明のホース巻取り装置(10)は次の(a)〜(e)を有している。
(a)ホース(15)が巻回されるホースリール(30)
(b)ホースリール(30)へのホース(15)の整列巻きのためのホースガイド部(47)をもつ操作部材(40)
(c)ホースリール(30)の軸方向に平行な第1の方向と第1の方向に対してほぼ直角の第2の方向へ変位自在に操作部材(40)を支持する支持装置(49)
(d)一端側から他端側への伝達変位量が第1の方向への操作部材(40)の単位変位量に対してよりも第2の方向への操作部材(40)の単位変位量に対しての方が大きくなるように一端側を操作部材(40)へ接続されている変位伝達部材(37)
(e)変位伝達部材(37)の他端側により変位操作されてホースリール(30)への駆動回転力を断接する動力断接装置(35,72)
【0006】
ホースリール(30)へのホース(15)の巻取り時では、作業者は操作部材(40)を第2の方向の一方側へ変位させる。変位伝達部材(37)は、十分な変位量を他端側へ伝達し、動力断接装置(35,72)は、変位伝達部材(37)からの伝達変位により操作されて、接になる。こうして、原動機等からの駆動回転力がホースリール(30)へ伝達され、ホースリール(30)は巻取り方向へ回転し、ホース(15)を巻取っていく。これに並行して、作業者は、操作部材(40)を第2の方向の一方側に保持しつつ、すなわち、動力断接装置(35,72)を接状態に保持しつつ、ホースリール(30)へのホース(15)の巻取りに合わせながら、第1の方向へ往復変位させる。これにより、操作部材(40)のホースガイド部(47)がホースリール(30)の軸方向へ往復変位し、ホース(15)はホースリール(30)に整列巻きされる。なお、操作部材(40)を第2の方向の一方側に保持しつつ、ホース(15)の整列巻きのために、操作部材(40)を第1の方向へ往復変位させると、これに伴い、変位伝達部材(37)の一端側は変位することになるが、この変位に対しては、変位伝達部材(37)は、向き等の設定により、他端側への伝達変位量を小さくするので、動力断接装置(35,72)の操作量は、動力断接装置(35,72)効き代の範囲内に収まり、動力断接装置(35,72)は接の状態を保持する。
【0007】
こうして、作業者(19)は操作部材(40)のみの操作により動力断接装置(35,72)の断接操作とホース(15)の整列巻き操作とを行うことができ、片方の手が空くことになり、この空いた方の手で、ホースリール(30)から逸脱しそうになったホース(15)や、ホース巻取り装置(10)の部位へ絡みそうになったホース(15)を適宜操作して、作業を円滑に行うことができる。
【0008】
この発明のホース巻取り装置(10)によれば、支持装置(49)は、ホースリール(30)の軸方向範囲のほぼ中心に位置し、操作部材(40)は、上端部において第1の方向へ揺動自在となるように、下端部において支持装置(49)に支持されている。
【0009】
支持装置 (49) がホースリール (30) の軸方向範囲のほぼ中心に位置し、操作部材 (40) が、上端部において第1の方向へ揺動自在となるように、下端部において支持装置 (49) に支持されているので、操作部材 (40) は、ホース整列巻き操作の際に、第1の方向へ左右均等に振れることになり、これにより、操作部材 (40) の最大変位量を減少できる。結果、第1の方向への操作部材(40)の往復変位に対する変位伝達部材(37)によるその一端側から他端側への変位伝達の変動が抑制され、第1の方向への操作部材(40)の往復変位からの動力断接装置(35,72)の断接への影響が抑制される。
【0010】
この発明のホース巻取り装置(10)によれば、引張コイルばね(66)が、変位伝達部材(37)に直列結合され、操作部材(40)と動力断接装置(35)との間に介在している。
【0011】
整列巻きのための第1の方向への操作部材(40)の往復変位に対して、変位伝達部材(37)が一端側から他端側へ伝達する変位量は、引張コイルばね(66)の介在により、低減される。これにより、動力断接装置(35)は、第1の方向への操作部材(40)の往復変位から受ける影響を少なくされる。
【0012】
なお、動力断接装置(35)の断時では、すなわち、ホース(15)の巻取りを行っていないときは、整列巻きのために、操作部材(40)を往復変位することもないので、操作部材(40)の往復変位に対して、動力断接装置(35)の断接が切替わる事態に対策は特に必要ない。
【0013】
この発明のホース巻取り装置(10)によれば、薬液散布機(10)に装備され、ホース(15)の先端側には、薬液散布ノズル(16)が装着され、ホース(15)を介して薬液散布ノズル(16)へ薬液が送出されるようになっている。
【0014】
薬液散布機(10)では、薬液散布作業では、噴霧ノズル(16)側に一人の作業者(17)が必要になるとともに、薬液散布機(10)側にもホース(15)巻取り待機の作業者(19)か必要になる。そして、ホースリール(30)からのホース(15)の繰り出し、ホースリール(30)への巻戻しが頻繁に繰り返されるので、薬液散布機(10)側に待機した作業者(19)の作業量は多い。したがって、薬液散布機(10)へのホース巻取り装置(10)の適用効果は高い。
【0015】
【発明の実施の形態】
以下、発明の実施の形態について図面を参照して説明する。
図1は動力噴霧機セット10を使った薬液散布作業状態を示す図である。薬液タンク11は、動力噴霧機セット10の近傍に置かれ、薬液を貯留する。ストレーナ13は薬液タンク11の薬液中に位置し、薬液タンク11内の薬液は、ストレーナ13から吸入ホース12を経て動力噴霧機セット10の三連往復ポンプ28の吸入口へ吸入される。また、動力噴霧機セット10の調圧弁41(図2)からの余液は余液ホース14を介して薬液タンク11内へ戻される。ホース15は動力噴霧機セット10から引き出され、噴霧ノズル16がホース15の先端側に取り付けられている。第1の作業者17は、噴霧ノズル16を把持しつつ、圃場内を歩行して、圃場の作物18へ噴霧ノズル16の複数の噴孔より薬液を散布する。第2の作業者19は、動力噴霧機セット10の傍に待機し、整列巻きレバー40を操作する。
【0016】
図2は動力噴霧機セット10の詳細図である。フレーム25の下部の一方の半部には、台部26が取り付けられ、エンジン27及び三連往復ポンプ28が台部26に載置固定される。三連往復ポンプ28の吸入口には吸入ホース12が接続され、三連往復ポンプ 28の吐出口は調圧弁41を経てホース15の基端側へ接続される。調圧弁41の余液口は余液ホース14を接続されている。原動機としてのエンジン27の回転動力はベルト(図示せず)を介して三連往復ポンプ28の駆動軸へ伝達される。スロットルレバー29は、フレーム25の上辺に揺動自在に取り付けられ、スロットルレバー29の揺動操作によりエンジン27の出力が増減する。ホースリール30はフレーム25の他方の半部においてフレーム25に回転自在に支持され、プーリ31,32は、それぞれ三連往復ポンプ28の駆動軸及びホースリール30の支軸に回転方向へ一体に取り付けられ、ベルト33を掛けられている。アーム対34は、ベルト33の下側においてフレーム25に揺動自在に取り付けられ、引張ばね36により起立方向へ付勢されている。ワイヤ部材37は、被覆材38と、被覆材38により被覆され両端部のみ被覆材38から露出するワイヤ39とを含む。整列巻きレバー40は、ホースリール30に対してエンジン27とは反対側においてフレーム25に揺動自在に取り付けられている。アーム対34は、フレーム25の下辺部に回動自在に結合し、起立位置と傾動位置との間で揺動自在であり、引張ばね36により起立位置の方へ付勢される。テンションプーリ35は、アーム対34の内側のアームの先端部に回動自在に結合し、アーム対34の傾動位置及び起立位置においてベルト33をそれぞれ弛緩状態及び緊張状態に切替えるようになっている。
【0017】
図3は整列巻きレバー40の詳細図である。整列巻きレバー40は、上端に取付けられて第2の作業者19により把持されるノブ46、ノブ46より少し下側でホースリール30のほぼ上端の高さにあってホース15を挿通される輪状のホースガイド部47、及び下端の円板部48を有している。ホースガイド部47の内径はホース15の径より少し大きい程度である。ステー51は、フレーム25の下辺に固定され、上方へ所定量突出している。ステー63は、円板部48より少し上側の整列巻きレバー40の部位に固設され、ステー63と回動ブラケット64とは、ホースリール30の軸方向に対して平行な水平線の周りに回動自在に結合している。ワイヤ部材37の被覆材38の端は、ステー51に当接、固定され、被覆材38から露出したワイヤ39は、ホースリール30の軸方向に対してほぼ直角の水平方向へ延び、先端において回動ブラケット64に結合している。
【0018】
図4はフレーム25への整列巻きレバー40の取付け部49の分解図である。ステー51はフレーム25に固定され、張出し部52はステー51から円板部48の方へ張出している。回動ブラケット53は二股部において水平方向両側から張出し部52を挟み、結合ピン54は、軸部を回動ブラケット53の二股部及び張出し部52の通孔に挿通されてから、先端部において抜け留めピン55を挿通されて、張出し部52及び回動ブラケット53からの抜けを阻止される。回動ブラケット53は、張出し部52とは反対側へ突出する軸部56を備え、軸部56は、基端側から先端側へ順番に大径円柱部57、大径円柱部57より小径で円板部48の肉厚より長い小径円柱部58、及び小径円柱部58よりさらに小径のねじ部59を有している。軸部56は、円板部48の中心孔に挿通され、小径円柱部58が円板部48の中心孔内に位置する。ねじ部59は円板部48から突出し、嵌め込み部60が軸部56の先端側から嵌められて、小径円柱部58の部位に嵌装し、小径円柱部58に対する円板部48の相対回転を許容するとともに、フランジ部において小径円柱部58からの円板部48の抜けを阻止する。ねじ部59には、嵌め込み部60が嵌装されてから、ナット62が螺合し、ナット62はワッシャ61及び嵌め込み部60のフランジ部を円板部48に締め付ける。整列巻きレバー40は、軸部56における円板部48の回転により、A−B方向へ揺動自在となり、また、結合ピン54の周りの張出し部52及び回動ブラケット53の相互の回転によりa−b方向へ揺動自在になる。
【0019】
ここで説明の便宜上、整列巻きレバー 40 についてA−B方向及びa−b方向へ次の位置を整列巻きレバー 40 の「初期位置」と呼ぶことにする。「初期位置」とは、A−B方向へは、整列巻きレバー 40 がホースリール 30 の軸方向範囲の中心に一致した位置、すなわち整列巻きレバー 40 が、その正面視で、ステー 51 と重なった位置であって、a−b方向へは、整列巻きレバー 40 をb側へ十分に偏倚した位置である。整列巻きレバー40が初期位置にあるときは、整列巻きレバー40のステー63はステー51から遠い方に位置し、ワイヤ39は、整列巻きレバー40側へ大きく引き出されている。これにより、アーム対34は、引張ばね36の引張力に抗して先端側を下方へ傾動させ、テンションプーリ35は、ベルト33から引き込まれた位置にあって、ベルト33は弛緩状態にあり、ベルト33を介してプーリ31からプーリ32へのエンジン27の回転動力の伝達は行われない。したがって、ホースリール30は回転を停止している。
【0020】
ホースリール30へホース15を巻取るときは、第2の作業者19(図1)は、ノブ46を把持して、最初に、ノブ46をa方向へ変位させる。これにより、アーム対34の内側アーム65bはステー51に接近し、ワイヤ部材37のワイヤ39は引張ばね36によりアーム対34の方へ移動する。これにより、アーム対34は起立状態になって、テンションプーリ35は、ベルト33を内周側の方へ大きく押し込んで、ベルト33を弛緩状態から緊張状態へ切替える。この結果、エンジン27の回転動力がベルト33を介してプーリ31からプーリ32へ伝達され、ホースリール30は巻取り方向へ回転駆動される。これにより、ホース15は、整列巻きレバー40のホースガイド部47を通ってホースリール30へ巻取られていくことになる。第2の作業者19は、ホースリール30へのホース15の巻取りに並行して、整列巻きレバー40をA−B方向へ往復動させる。これに伴い、整列巻きレバー40のホースガイド部47は、ホースリール30の上端高さ付近で、ホースリール30の軸方向へホースリール30の両端板間を往復変位し、ホース15は、ホースリール30の軸方向へホースガイド部47の対応位置でホースリール30へ巻取られて行き、整列状態でホースリール30へ巻取られる。整列巻きレバー40のA−B方向への往復変位に伴い、整列巻きレバー40のステー63もホースリール30の軸方向へ変位し、ステー51からのワイヤ39の引き出し量が変化する。しかし、ステー51は、a−b方向に対して面を直角とされ、ワイヤ39はステー51からa−b方向へ引き出されるように設定されているので、ステー51からのワイヤ39の引出し量の変化は、A−B方向への整列巻きレバー40の単位変位量に対しての方はa−b方向への整列巻きレバー40の単位変位量に対してよりはるかに小さく、また、整列巻きレバー40のA−B方向の変位範囲中心はホースリール30の軸方向長さ範囲の中心となっているので、テンションプーリ35の接時の整列巻きのための整列巻きレバー40のA−B方向の往復変位に対してワイヤ部材37を介してアーム対34へ伝達される変位量の変動は小さく、この小さい変位量は、クラッチとしてのテンションプーリ35の効き代により吸収され、テンションプーリ35は支障なく接位置に保持される。
【0021】
図5はワイヤ部材37とアーム対34との間に引張コイルばね66を介在させた構造を示している。ホースリール30へホース15を巻取る前述の作用説明は、引張コイルばね66の設けられていない動力噴霧機セット10についてのものであるが、引張コイルばね66の追加について説明する。図5では、アーム対34はフレーム25を間に挟んで一体揺動する外側アーム65aと内側アーム65bとを備え、ワイヤ39のアーム対34側の端は引張コイルばね66を介して外側アーム65aへ結合している。引張コイルばね66がワイヤ39と外側アーム65aとの間に介在する結果、ワイヤ39の変位の増減量は、低減されて、外側アーム65aへ伝達される。したがって、テンションプーリ35を接位置に保持しつつ、整列巻きのために整列巻きレバー40をA−B方向へ往復変位する際に、アーム対34が、受ける操作量の変動は抑制され、テンションプーリ35の接を良好に維持できる。

The present invention relates to a hose winding device provided in a chemical sprayer or the like, and more particularly, to a hose winding device for manually displacing a hose guide portion for aligned winding when winding a hose on a hose reel. It is about.
[0002]
[Prior art]
FIG. 7 is a perspective view of a conventional power sprayer set 84, and FIG. 8 is a perspective view of an alignment winding lever 85 of FIG. The same parts as those of the power sprayer set 10 according to the embodiment of the present invention described later are designated by the same reference numerals, and description thereof will be omitted, and only the main points will be described. The alignment winding lever 85 has a hose guide portion 47 at a position slightly below the upper end. The stay 87 is fixed to the lower side of the frame 25, and the plate 88 at the lower end of the alignment winding lever 85 is attached to the projecting end of the stay 87 by the support pin 89 at a right angle to the axial direction of the hose reel 30. It is rotatably supported around a horizontal line. The hose guide 47 reciprocates in the axial direction of the hose reel 30 by the swing of the alignment winding lever 85 around the support pin 89. On the other hand, the clutch handle 86 has its base end fixed to the outer arm of the arm pair 34 and swings integrally with the arm pair 34. When the clutch handle 86 is tilted downward against the pulling force of the tension spring 36, the tension pulley 35 releases the tension of the belt 33, and the transmission of the engine power from the pulley 31 to the pulley 32 by the belt 33 is cut off. To When the clutch handle 86 is raised upward, the clutch handle 86 is tilted upward by the tensile force of the tension spring 36, and the tension pulley 35 is pressed against the belt 33 with a large force, so that the belt 33 is in a tension state, and When the transmission of the engine power from the pulley 31 to the pulley 32 is brought into contact, the hose reel 30 is driven to rotate in the winding direction of the hose 15.
[0003]
[Problems to be solved by the invention]
In the chemical spraying operation, there are usually two workers, one worker operates a spray nozzle at the tip of the hose 15, and the other worker stands by at the power sprayer set 84, When winding the fifteen, the alignment winding lever 85 and the clutch handle 86 are operated. In the conventional power sprayer set 84, the worker waiting on the power sprayer set 84 side pays attention to the worker on the spray nozzle side when winding the hose 15, while keeping the alignment winding lever 85 and the clutch handle 86 It is necessary to hold and operate with the left and right hands. Therefore, it is troublesome, and since both hands are closed, even if the hose 15 is likely to deviate from the hose reel 30 or to be entangled with the portion of the power sprayer set 84, it has not been possible to quickly cope with it.
[0004]
An object of the present invention is to provide a hose winding device that can overcome the above-mentioned problems.
[0005]
[Means for Solving the Problems]
The hose winding device (10) of the present invention has the following (a) to (e).
(A) Hose reel (30) around which hose (15) is wound
(B) an operating member (40) having a hose guide (47) for aligning and winding the hose (15) around the hose reel (30);
(C) a support device (49) for supporting the operation member (40) so as to be displaceable in a first direction parallel to the axial direction of the hose reel (30) and a second direction substantially perpendicular to the first direction.
(D) The unit displacement of the operating member (40) in the second direction is greater than the unit displacement of the operating member (40) in the first direction from the transmitted displacement from one end to the other end. The displacement transmitting member (37) whose one end is connected to the operating member (40) so that
(E) A power connection / disconnection device (35, 72) that is displaced by the other end of the displacement transmission member (37) to connect / disconnect the drive torque to the hose reel (30).
[0006]
When winding the hose (15) around the hose reel (30), the operator displaces the operation member (40) to one side in the second direction. The displacement transmitting member (37) transmits a sufficient amount of displacement to the other end, and the power connection / disconnection device (35, 72) is operated by the transmitted displacement from the displacement transmitting member (37) to come into contact. Thus, the driving torque from the prime mover or the like is transmitted to the hose reel (30), and the hose reel (30) rotates in the winding direction and winds the hose (15). In parallel with this, the operator holds the operating member (40) on one side in the second direction, that is, while holding the power disconnecting / connecting device (35, 72) in contact with the hose reel (40). The reciprocating displacement in the first direction is performed while the hose (15) is wound around 30). As a result, the hose guide portion (47) of the operation member (40) reciprocates in the axial direction of the hose reel (30), and the hose (15) is aligned and wound around the hose reel (30). In addition, when the operating member (40) is reciprocated in the first direction to align and wind the hose (15) while holding the operating member (40) on one side in the second direction, The one end of the displacement transmitting member (37) is displaced, but the displacement transmitting member (37) reduces the amount of displacement transmitted to the other end by setting the direction and the like. Therefore, the amount of operation of the power connection / disconnection device (35, 72) is within the range of the effect of the power connection / disconnection device (35, 72), and the power connection / disconnection device (35, 72) maintains the connected state. .
[0007]
Thus, the operator (19) can perform the operation of connecting and disconnecting the power connection / disconnection device (35, 72) and the operation of aligning and winding the hose (15) by operating only the operation member (40). With the vacant hand, the hose (15) that is likely to deviate from the hose reel (30) or the hose (15) that is likely to become entangled with the part of the hose winding device (10) is used. The operation can be performed smoothly as appropriate.
[0008]
According to the hose winding device (10) of the present invention, the support device (49) is located substantially at the center of the axial range of the hose reel (30), and the operating member (40) is the first member at the upper end. The lower end is supported by a support device (49) so as to be swingable in the direction.
[0009]
The supporting device (49) is located substantially at the center of the axial range of the hose reel (30) , and the operating member (40) is swingable in the first direction at the upper end. because it is supported (49), the operating member (40), when the hose regular winding operation, will be deflected equally right and left to the first direction, thereby, the maximum displacement of the operating member (40) Can be reduced. As a result, the displacement of the displacement transmitting member (37) from one end side to the other end side by the displacement transmitting member (37) with respect to the reciprocal displacement of the operating member (40) in the first direction is suppressed, and the operating member ( The influence of the reciprocating displacement of (40) on the connection and disconnection of the power connection / disconnection device (35, 72) is suppressed.
[0010]
According to the hose winding device (10) of the present invention, the tension coil spring (66) is connected in series to the displacement transmitting member (37), and is provided between the operating member (40) and the power connecting / disconnecting device (35). Intervening.
[0011]
With respect to the reciprocating displacement of the operating member (40) in the first direction for the alignment winding, the displacement transmitted by the displacement transmitting member (37) from one end to the other end is the amount of displacement of the tension coil spring (66). It is reduced by the intervention. Thus, the power connection / disconnection device (35) is less affected by the reciprocating displacement of the operation member (40) in the first direction.
[0012]
When the power connecting / disconnecting device (35) is disconnected, that is, when the hose (15) is not wound, the operating member (40) is not reciprocated for the alignment winding. No countermeasure is necessary particularly in the case where the connection / disconnection of the power connection / disconnection device (35) is switched with respect to the reciprocal displacement of the operation member (40).
[0013]
According to the hose winding device (10) of the present invention, a chemical spraying nozzle (16) is attached to the tip of the hose (15), which is mounted on the chemical sprayer (10). The chemical is delivered to the chemical spray nozzle (16).
[0014]
The chemical sprayer (10) requires one worker (17) on the side of the spray nozzle (16) and the hose (15) on the side of the chemical sprayer (10) for the chemical spraying operation. An operator (19) is required. Since the feeding of the hose (15) from the hose reel (30) and the rewinding to the hose reel (30) are frequently repeated, the amount of work of the worker (19) waiting on the chemical sprayer (10) side. Are many. Therefore, the application effect of the hose winding device (10) to the chemical sprayer (10) is high.
[0015]

The arm pair 34 is rotatably connected to the lower side of the frame 25, is swingable between a standing position and a tilting position, and is urged toward the standing position by a tension spring 36. The tension pulley 35 is rotatably connected to the tip of the arm inside the arm pair 34, and switches the belt 33 between the slanted position and the upright position of the arm pair 34 between the relaxed state and the tensioned state, respectively.
[0017]
FIG. 3 is a detailed view of the alignment winding lever 40. The alignment winding lever 40 is attached to the upper end and has a knob 46 which is gripped by the second operator 19, a ring-like shape which is slightly lower than the knob 46, substantially at the height of the upper end of the hose reel 30, and through which the hose 15 is inserted. And a disc portion 48 at the lower end. The inner diameter of the hose guide 47 is slightly larger than the diameter of the hose 15. The stay 51 is fixed to the lower side of the frame 25 and protrudes upward by a predetermined amount. The stay 63 is fixed to the portion of the alignment winding lever 40 slightly above the disk portion 48, and the stay 63 and the rotating bracket 64 rotate around a horizontal line parallel to the axial direction of the hose reel 30. It is freely connected. The end of the covering material 38 of the wire member 37 abuts and is fixed to the stay 51, and the wire 39 exposed from the covering material 38 extends in a horizontal direction substantially perpendicular to the axial direction of the hose reel 30, and turns at the tip. It is connected to the moving bracket 64.
[0018]
FIG. 4 is an exploded view of a mounting portion 49 of the alignment winding lever 40 to the frame 25. The stay 51 is fixed to the frame 25, and the projecting portion 52 projects from the stay 51 toward the disk portion 48. The pivot bracket 53 sandwiches the projecting portion 52 from both sides in the horizontal direction at the forked portion, and the coupling pin 54 comes off at the tip portion after the shaft portion is inserted into the through hole of the forked portion of the rotating bracket 53 and the projecting portion 52. The retaining pin 55 is inserted to prevent the protrusion 52 and the pivot bracket 53 from coming off. The rotating bracket 53 includes a shaft portion 56 protruding to the opposite side to the overhang portion 52. The shaft portion 56 has a large-diameter cylindrical portion 57 and a smaller diameter than the large-diameter cylindrical portion 57 in order from the base end to the distal end. It has a small-diameter cylindrical portion 58 longer than the thickness of the disk portion 48 and a screw portion 59 having a smaller diameter than the small-diameter cylindrical portion 58. The shaft portion 56 is inserted into the center hole of the disk portion 48, and the small-diameter cylindrical portion 58 is located in the center hole of the disk portion 48. The screw portion 59 protrudes from the disk portion 48, and the fitting portion 60 is fitted from the distal end side of the shaft portion 56 to fit into the small-diameter cylindrical portion 58, and controls the relative rotation of the disk portion 48 with respect to the small-diameter cylindrical portion 58. While permitting, the disc portion 48 is prevented from coming off from the small-diameter cylindrical portion 58 at the flange portion. After the fitting portion 60 is fitted into the screw portion 59, a nut 62 is screwed into the screw portion 59, and the nut 62 fastens the washer 61 and the flange portion of the fitting portion 60 to the disk portion 48. The alignment winding lever 40 is swingable in the AB direction by the rotation of the disc portion 48 on the shaft portion 56, and the rotation of the projection 52 and the rotation bracket 53 around the coupling pin 54 causes a It becomes swingable in the -b direction.
[0019]
For convenience of explanation, will be about regular winding lever 40 is referred to as "initial position" of the regular winding lever 40 to the next location to A-B direction and a-b direction. The “initial position” is a position where the alignment winding lever 40 coincides with the center of the axial range of the hose reel 30 in the AB direction, that is, the alignment winding lever 40 overlaps the stay 51 in a front view thereof . This is a position where the alignment winding lever 40 is sufficiently biased toward the b side in the ab direction . When the alignment winding lever 40 is in the initial position, the stay 63 of the alignment winding lever 40 is located farther from the stay 51, and the wire 39 is largely drawn out to the alignment winding lever 40 side. As a result, the arm pair 34 tilts the distal end side downward against the tensile force of the tension spring 36, the tension pulley 35 is at the position where it is pulled in from the belt 33, and the belt 33 is in a relaxed state, The rotation power of the engine 27 is not transmitted from the pulley 31 to the pulley 32 via the belt 33. Therefore, the hose reel 30 has stopped rotating.
[0020]
When winding the hose 15 around the hose reel 30, the second operator 19 (FIG. 1) grips the knob 46 and first displaces the knob 46 in the direction a. Thus, the inner arm 65b of the arm pair 34 approaches the stay 51, and the wire 39 of the wire member 37 is moved toward the arm pair 34 by the tension spring 36. As a result, the arm pair 34 is in the upright state, and the tension pulley 35 largely pushes the belt 33 toward the inner peripheral side, thereby switching the belt 33 from the relaxed state to the tensioned state. As a result, the rotational power of the engine 27 is transmitted from the pulley 31 to the pulley 32 via the belt 33, and the hose reel 30 is driven to rotate in the winding direction. As a result, the hose 15 is wound around the hose reel 30 through the hose guide 47 of the alignment winding lever 40. The second worker 19 reciprocates the alignment winding lever 40 in the AB direction in parallel with the winding of the hose 15 on the hose reel 30. Along with this, the hose guide portion 47 of the alignment winding lever 40 reciprocates between both end plates of the hose reel 30 in the axial direction of the hose reel 30 near the upper end height of the hose reel 30, and the hose 15 At the corresponding position of the hose guide portion 47 in the axial direction of the hose 30, it is wound on the hose reel 30, and is wound on the hose reel 30 in an aligned state. With the reciprocating displacement of the alignment winding lever 40 in the AB direction, the stay 63 of the alignment winding lever 40 is also displaced in the axial direction of the hose reel 30, and the amount of the wire 39 pulled out from the stay 51 changes. However, since the stay 51 has a surface perpendicular to the a-b direction and the wire 39 is set so as to be pulled out from the stay 51 in the a-b direction, the amount of the wire 39 pulled out from the stay 51 is limited. The change is much smaller for the unit displacement of the alignment winding lever 40 in the AB direction than for the unit displacement of the alignment winding lever 40 in the ab direction. Since the center of the displacement range of the hose reel 40 in the AB direction is the center of the axial length range of the hose reel 30, the alignment winding lever 40 in the AB direction of the alignment winding lever 40 for the alignment winding when the tension pulley 35 is in contact with the hose reel 30. The variation of the displacement transmitted to the arm pair 34 via the wire member 37 with respect to the reciprocal displacement is small, and this small displacement is absorbed by the effective force of the tension pulley 35 as a clutch, and the tension is reduced. Over Li 35 is held in without trouble contacting position.
[0021]
FIG. 5 shows a structure in which a tension coil spring 66 is interposed between the wire member 37 and the arm pair 34. The above description of the operation of winding the hose 15 around the hose reel 30 is for the power sprayer set 10 in which the extension coil spring 66 is not provided, but the addition of the extension coil spring 66 will be described. In FIG. 5, the arm pair 34 includes an outer arm 65a and an inner arm 65b that swing together with the frame 25 interposed therebetween. The end of the wire 39 on the arm pair 34 side is connected to the outer arm 65a via a tension coil spring 66. Connected to As a result of the tension coil spring 66 being interposed between the wire 39 and the outer arm 65a, the amount of increase or decrease in the displacement of the wire 39 is reduced and transmitted to the outer arm 65a. Therefore, when the alignment winding lever 40 is reciprocated in the AB direction for the alignment winding while holding the tension pulley 35 in the contact position, the fluctuation of the operation amount received by the arm pair 34 is suppressed. 35 contact can be maintained favorably.
[0022]
FIG. 6 is another configuration diagram of the power sprayer set 10. 2 are indicated by the same reference numerals, and only the differences will be described. The difference from FIG. 1 is the connection / disconnection structure of the rotational power transmitted from the triple reciprocating pump 28 to the hose reel 30. The double arm lever 70 is swingably supported on the lower side of the frame 25. One of the arms has a pressure roller 72 rotatably attached to the distal end thereof, and the wire 39 is locked at the intermediate portion. ing. Both ends of the tension coil spring 71 are locked to the other arm of the double arm lever 70 and the frame 25, and the drive roller 73 moves the double arm lever 70 from the first swing position to the second swing position. The triple reciprocating pump 28 is integrally attached to the end of the drive shaft in the rotational direction. In the first swing position of the double arm lever 70, the pressing roller 72 moves downward away from the end plate 74 and the driving roller 73 of the hose reel 30, and moves from the driving roller 73 through the pressing roller 72. Transmission of engine power to plate 74 has been cut off. In the second swinging position of the double arm lever 70, the pressing roller 72 moves up and is pressed against the end plate 74 and the driving roller 73 of the hose reel 30 at the same time, and from the driving roller 73 via the pressing roller 72 to the end plate. Engine power to 74 is transmitted. When the alignment winding lever 40 is in the initial position, the wire 39 is moving toward the alignment winding lever 40, the double arm lever 70 is in the first swing position, and the hose reel 30 is stopped. . When the alignment winding lever 40 is operated in the direction a in the a-b direction, the wire 39 moves toward the double arm lever 70, the double arm lever 70 is in the second swing position, and the hose reel 30 is The hose 15 is driven to rotate in the winding direction. In this state, the second worker 19 reciprocates the alignment winding lever 40 in the AB direction for the alignment winding.
