特開２０１０−１３９５４号公報JP 2010-13594 A

前記送風機に連結される筒状の噴管の先端には切り欠き部が形成されて、作業時に噴管先端の噴射孔を地面に押し付けることにより、切り欠き部から前方（または後方または側方）に噴射され、壁などの隅部に溜まるゴミ等を容易に吹き飛ばせるようにしていた。
しかし、前記送風作業機によると噴管の先端を地面に押し付けないと切り欠き部の方向へ噴射できない。つまり、噴管の先端を地面に押し付けるまでは、周囲から噴き出して、所望の方向へ飛ばすことができない場合があり、また、移動しながら作業を行う場合には先端を密閉することが難しいため、切り欠き部の方向への噴出力が弱くなり、所望の方向へゴミ等を集めることが難しい場合があった。
そこで、本発明はかかる課題に鑑み、作業者が落ち葉やゴミ等を寄せ集める作業を行う際に、送風機の噴管を壁や地面に押し付けることなく、所望の方向に容易に集められる送風作業機を提供する。 A notch is formed at the tip of the cylindrical nozzle connected to the blower, and the nozzle at the tip of the nozzle is pressed against the ground during operation, so that the front (or rear or side) from the notch. The dust that is sprayed onto the corners of the walls and the like is easily blown away.
However, according to the blower working machine, it is impossible to inject in the direction of the notch unless the tip of the jet tube is pressed against the ground. In other words, until the tip of the jet tube is pressed against the ground, it may not be able to blow out from the surroundings and fly in the desired direction, and it is difficult to seal the tip when working while moving, In some cases, it is difficult to collect dust or the like in a desired direction because the jet power in the direction of the notch is weakened.
Therefore, in view of such a problem, the present invention provides a blower working machine that can be easily gathered in a desired direction without pressing the blower's jet tube against the wall or the ground when the worker collects fallen leaves and dust. I will provide a.

The The back support 11 is provided with a backpack belt (not shown), and an operator can carry the blower working machine 1 by putting his arm through the backpack belt. In addition, an engine 20, a blower 30, a fuel tank 50, and the like are placed on the support portion 12.

前記エンジン２０は、前記送風機３０を回転駆動するための原動機として機能するもので、正立姿勢（縦置き、出力軸は前後方向）で搭載され、また、前記エンジン２０と前記支持部１２との間には、前記エンジン２０用の燃料タンク５０が配設されている。   The engine 20 functions as a prime mover for rotationally driving the blower 30 and is mounted in an upright posture (vertically placed, the output shaft is in the front-rear direction). Also, the engine 20 and the support portion 12 A fuel tank 50 for the engine 20 is disposed therebetween.

また、図１に示すように、前記エンジン２０の後面にはリコイルスタータ２１が設けられており、該リコイルスタータ２１はグリップ部分２１ａを引くことによりマグネットを回転させてコイルに高電圧を発生させてピストンの上下動に合わせて点火させる。これにより、作業者はリコイルスタータ２１を手動で操作することで、エンジン２０を始動させることができる。   Further, as shown in FIG. 1, a recoil starter 21 is provided on the rear surface of the engine 20, and the recoil starter 21 rotates a magnet by pulling a grip portion 21a to generate a high voltage in the coil. Ignite according to the vertical movement of the piston. Thereby, the operator can start the engine 20 by operating the recoil starter 21 manually.

前記送風機３０は、図２に示すように、基本的には、遠心式でファンケース３１と、該ファンケース３１内に配置されたファン３２とからなり、該ファン３２は、その中心がファン軸３３に固定され、ファン軸３３はエンジン２０の出力軸と連結され回転駆動可能に構成されている。   As shown in FIG. 2, the blower 30 basically includes a centrifugal fan case 31 and a fan 32 disposed in the fan case 31, and the center of the fan 32 is a fan shaft. The fan shaft 33 is connected to the output shaft of the engine 20 and is configured to be rotationally driven.

前記ファンケース３１は、前記ファン３２を収納するファン収納部３１ａと上部通路３１ｂとから構成されている。前記ファン収納部３１ａと上部通路３１ｂは連通しており前記ファン３２によって加圧された空気が上部通路３１ｂへと送られる。また、前記ファンケース３１の背負い架台１０側には空気取入口３４が設けられている。   The fan case 31 includes a fan storage portion 31a for storing the fan 32 and an upper passage 31b. The fan accommodating portion 31a and the upper passage 31b communicate with each other, and air pressurized by the fan 32 is sent to the upper passage 31b. In addition, an air intake 34 is provided on the back side of the fan case 31.

外部空気は、前記送風機３０と前記背負い架台１０との間の空間を通じて、前記空気取入口３４から吸入されて、前記ファン３２で、所定の速度と圧力を与えられ、加速及び加圧せしめられる。そして、加圧された空気が前記ファンケース３１の上部通路３１ｂを通り、吐出口３５から噴管４０へと噴出されるようになっている。   External air is sucked from the air inlet 34 through the space between the blower 30 and the backrest 10 and given a predetermined speed and pressure by the fan 32 to be accelerated and pressurized.

前記送風機３０の吐出口３５は、ゴム等の可撓性を有するパイプで構成され、前記送風作業機１を背負った作業者の一方側の脇下後方で水平方向に突出するように曲げられている。この吐出口３５には、噴管４０が連結されるようになっている。   The discharge port 35 of the blower 30 is made of a flexible pipe such as rubber, and is bent so as to protrude in the horizontal direction behind the armpit on one side of the worker carrying the blower working machine 1. Yes. A jet tube 40 is connected to the discharge port 35.

このように構成したことにより、前記送風作業機１は、図３に示すように、作業者が背負って落ち葉やゴミ等を寄せ集める作業をすることができるものであり、前記作業にあたって、前記エンジン２０を始動させると図示せぬクランク軸（出力軸）が回動し、前記クランク軸に連結された前記ファン軸３３を介して前記ファン３２が回転し、該回転により前記空気取入口３４から空気を吸入して前記ファンケース３１内に導入し、風を起して、前記風を前記吐出口３５から噴出するものである。   By configuring in this way, the blower working machine 1 can carry out the work of gathering fallen leaves, dust, etc. on the back of the operator, as shown in FIG. When the motor 20 is started, a crankshaft (output shaft) (not shown) rotates, and the fan 32 rotates through the fan shaft 33 connected to the crankshaft. Is introduced into the fan case 31 to generate a wind, and the wind is ejected from the discharge port 35.

次に、本発明の要部である噴管４０の構成について図３から図６を用いて説明する。
前記噴管４０は、図３及び図５に示すように、連結部４１、蛇腹状のフレキシブル管４２、噴射管４３、グリップ４４、噴射方向制御部材６から構成されている。 Next, the structure of the injection tube 40 which is the principal part of this invention is demonstrated using FIGS.
As shown in FIGS. 3 and 5, the injection tube 40 includes a connecting portion 41, a bellows-like flexible tube 42, an injection tube 43, a grip 44, and an injection direction control member 6.

前記連結部４１は噴管４０を吐出口３５に取り付けるための部分であり、連結部４１を吐出口３５に嵌合して結束バンド等で固定する。前記フレキシブル管４２は蛇腹状に構成されており、その向きを自由に変更することが可能となっている。つまり、フレキシブル管４２の部分で折れ曲げたり捩じったりすることを可能としている。また、前記フレキシブル管４２の端部は噴射管４３に連結されている。これにより、前記噴射管４３は送風機３０に対して自由に向きを変更することができ、作業者は送風機３０を背負いながら、送風したい場所に対して噴射管４３を向けることが可能となる。なお、フレキシブル管４２は本発明では蛇腹状に構成されているが、フレキシブル管４２の構成はこれに限定するものではなく、例えば可撓性の有る素材によって構成することも可能である。   The connecting portion 41 is a portion for attaching the injection tube 40 to the discharge port 35, and the connecting portion 41 is fitted into the discharge port 35 and fixed with a binding band or the like. The flexible tube 42 has a bellows shape, and its direction can be freely changed. That is, the flexible tube 42 can be bent or twisted. The end of the flexible tube 42 is connected to the injection tube 43. Thereby, the direction of the said injection pipe 43 can be freely changed with respect to the air blower 30, and it becomes possible for the operator to point the injection pipe 43 toward the place which wants to blow air, carrying the air blower 30 on the back. In the present invention, the flexible tube 42 is configured in a bellows shape. However, the configuration of the flexible tube 42 is not limited to this, and may be configured of, for example, a flexible material.

前記噴射管４３は円筒状に構成されており、その中途部の外周面にグリップ４４が設けられ、噴射管４３の先端に噴射方向制御部材６が設けられる。
前記グリップ４４は本実施形態では棒状としているが、その形状は限定するものではなく、Ｌ字状やＵ字状等であってもよい。こうして、作業者はグリップ４４を握って噴射方向を調節して作業するようにしている。 The injection tube 43 is formed in a cylindrical shape, and a grip 44 is provided on the outer peripheral surface of the middle portion thereof, and an injection direction control member 6 is provided at the tip of the injection tube 43.
Although the grip 44 has a rod shape in the present embodiment, the shape thereof is not limited, and may be an L shape, a U shape, or the like. Thus, the operator holds the grip 44 and works by adjusting the injection direction.

前記噴射方向制御部材６は、有底の円筒状に構成され、一端が開口されて噴管４０の先端に着脱可能に取り付けられ、他端が蓋状に閉じられ、側面には少なくとも一つの噴射孔が開口されている。噴射方向制御部材６は作業に応じて付け替えることにより、先端から噴射される風量や風向や広がり等を調節可能としている。   The injection direction control member 6 has a bottomed cylindrical shape, and has one end opened and detachably attached to the tip of the injection tube 40, the other end closed in a lid shape, and at least one injection on the side surface. A hole is opened. By changing the injection direction control member 6 according to the work, it is possible to adjust the air volume, the wind direction, the spread, and the like injected from the tip.

噴射方向制御部材６は前記噴射管４３に対して着脱可能とするために、図６に示すように、前記噴射管４３の先端部の外周には、凸部４３a・４３aが所定角度（本実施形態では１８０度）毎に配置されている。一方、噴射方向制御部材６の一端（開口側）外周には、前記凸部４３a・４３ａの位置及び形状に合わせて外側に突出するように嵌合溝６ａ・６ａが形成されている。嵌合溝６ａは噴射方向制御部材６の開口端から軸心と平行に底側へ所定距離延びた後に円周方向に曲げられ、その先端部に一部くびれ部６ｂを設けている。   In order to make the injection direction control member 6 detachable with respect to the injection pipe 43, as shown in FIG. 6, the projections 43a and 43a are provided at predetermined angles (this embodiment) on the outer periphery of the tip of the injection pipe 43. It is arranged every 180 degrees). On the other hand, fitting grooves 6a and 6a are formed on the outer periphery of one end (opening side) of the injection direction control member 6 so as to protrude outward in accordance with the position and shape of the convex portions 43a and 43a. The fitting groove 6a extends from the opening end of the injection direction control member 6 to the bottom side in parallel with the axial center and then is bent in the circumferential direction, and a constricted portion 6b is provided at the tip thereof.

こうして、凸部４３a・４３ａの位置に嵌合溝６ａ・６ａを合わせて噴射方向制御部材６を軸心方向に差し込み、奥端に位置当たると周方向に回転して、くびれ部６ｂを越えることで、その回転位置で保持でき噴射方向を維持できるようにしている。噴射方向制御部材６を外すときは逆方向に回転させた後に軸心方向に引き抜くのである。なお、凸部４３a・４３ａと嵌合溝６ａ・６ａは１８０度位相が異なるように配置されているため、取付時に位相を変更することで、噴射孔（６１・６２）の噴出方向を１８０度ずらせることができる。また、前記所定角度を９０度とすることで、噴出方向を９０度ずつずらせることができる。この噴出方向を変更することで、前進しながらや後進しながらや横方向に移動しながら等、作業者の作業し易さに合わせて取付位置を容易に変更できるようにしている。なお、噴射管４３に対する噴射方向制御部材６の着脱構成は限定するものではなく、フランジを形成して固定する構成であったり、ネジ式等に構成することもできる。   In this way, the fitting grooves 6a and 6a are aligned with the positions of the convex portions 43a and 43a, the injection direction control member 6 is inserted in the axial direction, and when it hits the back end, it rotates in the circumferential direction and exceeds the constricted portion 6b. Thus, it can be held at the rotational position so that the injection direction can be maintained. When the ejection direction control member 6 is removed, it is pulled out in the axial direction after rotating in the reverse direction. In addition, since convex part 43a * 43a and fitting groove 6a * 6a are arrange | positioned so that a phase may differ 180 degree | times, by changing a phase at the time of attachment, the ejection direction of an injection hole (61 * 62) is 180 degree | times. Can be shifted. Further, by setting the predetermined angle to 90 degrees, the ejection direction can be shifted by 90 degrees. By changing the ejection direction, the mounting position can be easily changed in accordance with the ease of work of the operator, such as moving forward or backward or moving laterally. The attachment / detachment configuration of the injection direction control member 6 with respect to the injection pipe 43 is not limited, and may be a configuration in which a flange is formed and fixed, or a screw type or the like.

そして、噴射方向制御部材６の側面には少なくとも一つの噴射孔が開口されている。つまり、図４、図６に示すように、筒状の軸心に対して半径方向に開口する噴射孔６１が一つ開口される。該噴射孔６１は、円周に沿った長孔として、扇形状に所定幅で噴射できるようにしている。   At least one injection hole is opened on the side surface of the injection direction control member 6. That is, as shown in FIGS. 4 and 6, one injection hole 61 that opens in the radial direction with respect to the cylindrical axis is opened. The injection hole 61 is a long hole along the circumference so that it can be injected in a fan shape with a predetermined width.

このように構成することにより、壁際や歩道と道路の段差部や溝内や凹凸がある部分の清掃を行うときに、図４に示すように、前記噴射管４３を鉛直方向の姿勢として、噴射孔６１を地面と壁が交差する隅部に噴射孔６１を向け、噴射方向を壁と平行として、壁に沿って進行することで、容易に落ち葉やゴミ等を吹き飛ばし集めることができる。この時、従来のように、噴射管４３先端を地面に押し付ける必要がなく、反対方向に撒き散らすこともなく効率よく清掃作業ができるようになる。   By configuring in this way, when cleaning the wall, the sidewalk, the stepped part of the road, the inside of the groove or the part with the unevenness, as shown in FIG. By directing the injection hole 61 to the corner where the ground and the wall intersect the hole 61 and making the injection direction parallel to the wall and proceeding along the wall, it is possible to easily blow off and collect fallen leaves and dust. At this time, unlike the prior art, it is not necessary to press the tip of the injection pipe 43 against the ground, and the cleaning operation can be performed efficiently without being scattered in the opposite direction.

また、前記噴射孔６１は一つであると噴射範囲が狭く、円周方向に長い長孔とすると、吐出圧に中央と両側で差が生じるので、図７に示すように、複数の噴射孔６２・６２・・・を周方向に沿って配置する構成とすることもできる。この場合、噴射孔６２は前記噴射孔６１よりも開口面積を小さくして噴出力（風力）の低下を抑えることができる。   Further, if the number of the injection holes 61 is one, the injection range is narrow, and if the elongated holes are long in the circumferential direction, a difference occurs in the discharge pressure between the center and both sides. Therefore, as shown in FIG. 62, 62... Can be arranged along the circumferential direction. In this case, the injection hole 62 can have an opening area smaller than that of the injection hole 61 to suppress a decrease in the jet power (wind power).

また、噴射方向制御部材６には、図８に示すように、直径方向に二つの噴射孔６１・６３を設けることもできる。一方の噴射孔６１は前記と同様の大きな開口面積を有してゴミ等の吹き飛ばし用とし、他方の噴射孔６３は前記噴射孔６１よりも小さな開口面積を有し、反力軽減用とする。
このように噴射孔６１と噴射孔６３を対向配置する構成とすることにより、作業時には送風機３０から送られる風が噴射孔６１より噴射される風でゴミ等を吹き飛ばす。このとき、噴射孔６１からの噴射による反力が発生するが、噴射孔６１と反対側に開口した噴射孔６３からも反対方向に噴射されるため、反力が軽減され、作業者が噴管４０を支える力を軽減することができる。 Moreover, as shown in FIG. 8, the injection direction control member 6 can also be provided with two injection holes 61 and 63 in the diameter direction. One injection hole 61 has a large opening area similar to that described above and is used for blowing off dust and the like, and the other injection hole 63 has an opening area smaller than that of the injection hole 61 and is used for reducing reaction force.
Thus, by setting it as the structure which arrange | positions the injection hole 61 and the injection hole 63 facing each other, the wind sent from the air blower 30 blows off dust etc. with the wind injected from the injection hole 61 at the time of work. At this time, a reaction force due to the injection from the injection hole 61 is generated. However, since the injection force is also injected in the opposite direction from the injection hole 63 opened on the opposite side to the injection hole 61, the reaction force is reduced and the operator can The force that supports 40 can be reduced.

また、噴射方向制御部材６は、図９に示すように、二重の筒として、それぞれの筒に噴射孔６１・６４を設け、一方の筒を他方の筒に対して回転させることで、噴射孔６１と噴射孔６４が重複する開口面積を変更でき、噴射力や指向性を変更することができる。前記噴射孔６２・６２・・・や噴射孔６３も同様に重複面積を変更可能に構成することもできる。   Moreover, as shown in FIG. 9, the injection direction control member 6 is provided with injection holes 61 and 64 in each cylinder as a double cylinder and rotates one cylinder relative to the other cylinder. The opening area where the hole 61 and the injection hole 64 overlap can be changed, and the injection force and directivity can be changed. Similarly, the injection holes 62, 62,... And the injection holes 63 can be configured such that the overlapping area can be changed.

また、噴射方向制御部材６は、先端の開口部からの噴射方向を変更可能に構成することもできる。即ち、図１０に示すように、噴射方向制御部材６は、筒体の一方は前記同様に噴射管４３との嵌合部とし、他方は噴射孔６５とし、該噴射孔６５は軸心方向に対して斜め方向の開口面とし、噴射孔６５の一端に風向板７０が枢支されている。該風向板７０は前記噴射孔６５の大きさに合わせた大きさとして、回動することにより噴射方向を変更したり閉じたりすることができるようにしている。また、風向板７０と噴射方向制御部材６との間にはバネ７１が介装され、風向板７０を開ける方向に付勢している。該風向板７０は最大開けた状態は軸心と平行な状態となっている。さらに、風向板７０にはワイヤ７２の一端が連結され、該ワイヤ７２の他端はグリップ４４近傍に設けた調節レバー７３と連結されている。該調節レバー７３は任意回動位置で保持できるようにし、作業者が回動して容易に操作できるようにしている。   Moreover, the injection direction control member 6 can also be comprised so that the injection direction from the opening part of a front-end | tip can be changed. That is, as shown in FIG. 10, in the injection direction control member 6, one of the cylinders is a fitting portion with the injection pipe 43 as described above, the other is an injection hole 65, and the injection hole 65 is in the axial direction. On the other hand, the airflow direction plate 70 is pivotally supported at one end of the injection hole 65 with an oblique opening surface. The wind direction plate 70 has a size matching the size of the injection hole 65 so that the direction of injection can be changed or closed by rotating. Further, a spring 71 is interposed between the wind direction plate 70 and the injection direction control member 6 and biases it in the direction in which the wind direction plate 70 is opened. When the wind direction plate 70 is opened to the maximum, it is parallel to the axis. Further, one end of a wire 72 is connected to the wind direction plate 70, and the other end of the wire 72 is connected to an adjustment lever 73 provided in the vicinity of the grip 44. The adjustment lever 73 can be held at an arbitrary rotation position so that the operator can easily rotate and operate.

このような構成において、送風機３０による送風した作業時において、調節レバー７３を最大開いた状態では、噴射管４３から軸心方向の直進方向に噴射される。調節レバー７３を回動してワイヤ７２を介して風向板７０を閉じる方向に回動させると、噴射方向は徐々に曲げられ、風向板７０を９０度回動した状態では、軸心方向に対して直角方向に噴射させることができる。更に回動すると手前方向に噴射させることができるが、閉じると原動機の負荷が大きくなるので、調節レバー７３は閉じない位置まで回動できるようにしている。   In such a configuration, when the adjustment lever 73 is fully opened during the operation of blowing air by the blower 30, the jet pipe 43 is injected in the straight direction in the axial direction. When the adjustment lever 73 is rotated to rotate the wind direction plate 70 in the closing direction via the wire 72, the jetting direction is gradually bent. Can be sprayed at right angles. If it is further rotated, it can be ejected in the forward direction, but if it is closed, the load on the prime mover increases, so that the adjustment lever 73 can be rotated to a position where it does not close.

このように、噴射管４３からの吐出方向を、手元に配置した調節レバー７３を操作することにより容易に噴射方向を変更できるため、壁際に近づくに従って風向を前方から下方に変更することで、ゴミ等が舞い上がったり、周囲に散乱したりすることなく集めることが可能となる。   As described above, since the ejection direction from the ejection pipe 43 can be easily changed by operating the adjusting lever 73 disposed at hand, the dust direction can be reduced by changing the wind direction from the front toward the bottom as approaching the wall. Etc. can be collected without flying up or scattered around.

また、噴射方向制御部材６は、地面と平行に所定幅で清掃するようにもできる。即ち、噴射方向制御部材６は、図１１（ａ）、図１１（ｂ）に示すように、嵌合部６ｃと折れ曲がり部６ｄと吐出部６ｅから構成される。嵌合部６ｃは一端が噴射管４３の先端に嵌合して連通固定され、他端は折れ曲がり部６ｄに接続される。折れ曲がり部６ｄ、嵌合部６ｃと吐出部６ｅの間の角度を変更可能としている。具体的には、嵌合部６ｃの先端側面と吐出部６ｅの基部側側面に円筒嵌合部を形成して、回動可能に連通する。この円筒嵌合部には任意回動角度で保持できるデテント機構を設けている。吐出部６ｅは先端を閉じた有底筒状に構成し、側面には軸心方向に所定間隔をあけて複数の噴射孔６６・６６・・・が開口されている。但し、嵌合部６ｃと折れ曲がり部６ｄと吐出部６ｅは一体的に構成して、「へ」字状に構成することも可能である。   Moreover, the injection direction control member 6 can also be cleaned with a predetermined width parallel to the ground. That is, the injection direction control member 6 includes a fitting portion 6c, a bent portion 6d, and a discharge portion 6e as shown in FIGS. 11 (a) and 11 (b). One end of the fitting portion 6c is fitted and fixed to the tip of the injection pipe 43, and the other end is connected to the bent portion 6d. The angle between the bent part 6d, the fitting part 6c and the discharge part 6e can be changed. Specifically, a cylindrical fitting portion is formed on the tip side surface of the fitting portion 6c and the base side surface of the discharge portion 6e, and communicates with each other in a rotatable manner. The cylindrical fitting portion is provided with a detent mechanism that can be held at an arbitrary rotation angle. The discharge part 6e is formed in a bottomed cylindrical shape with a closed tip, and a plurality of injection holes 66, 66... Are opened on the side surface at predetermined intervals in the axial direction. However, the fitting portion 6c, the bent portion 6d, and the discharge portion 6e can be configured integrally and formed in a “h” shape.

このような構成において、嵌合部６ｃを噴射管４３の先端に嵌合固定し、作業者の身長や作業姿勢に合わせて、吐出部６ｅが地面と平行となるように折れ曲がり部６ｄで角度調節する。そして、送風機３０を作動させて噴射孔６６・６６・・・より噴射させながら吐出部６ｅが地面と平行、かつ、作業進行方向と直交する方向に向けた状態で作業を行う。従って、作業者は噴射管４３の先端を左右に振りながら作業をする必要がなくなり、真っ直ぐ進むだけで一定幅の清掃作業が可能となる。   In such a configuration, the fitting portion 6c is fitted and fixed to the tip of the injection tube 43, and the angle is adjusted by the bent portion 6d so that the discharge portion 6e is parallel to the ground according to the height and working posture of the operator. To do. Then, while the blower 30 is operated and ejected from the ejection holes 66, 66,..., The work is performed in a state in which the discharge part 6e is parallel to the ground and in a direction perpendicular to the work progress direction. Therefore, the operator does not have to work while swinging the tip of the ejection pipe 43 to the left and right, and a cleaning operation with a certain width can be performed only by moving straight.

また、前記噴射孔６６の代わりに、吐出方向を変更可能なノズル６７を設けることも可能である。即ち、図１１（ｃ）に示すように、ノズル６７は基部が球状に構成されて吐出孔を上下左右に角度変更可能に構成されている。こうして、左右に複数配置されたノズル６７・６７・・・を一定方向に向けたり、中央方向に向けたり、左右広げるように向けたりして、作業状態に合わせて、ゴミ等を容易に集められるようにすることができる。   Further, instead of the injection hole 66, a nozzle 67 capable of changing the discharge direction may be provided. That is, as shown in FIG. 11 (c), the nozzle 67 has a spherical base and is configured so that the angle of the discharge hole can be changed vertically and horizontally. In this way, it is possible to easily collect dust and the like according to the work state by directing the nozzles 67, 67,... Can be.

また、噴射方向制御部材６と地面との間で所定距離を維持できる接地体８０を設けることも可能である。即ち、図１３に示すように、接地体８０は車輪またはボール等の転動体、または、摺動抵抗が小さいソリ等により構成され、噴射方向制御部材６の先端に取り付けられる。なお、図１１に示す噴射方向制御部材６の場合、吐出部６ｅの基部側と先端側に取り付けることにより、より安定して作業ができる。   It is also possible to provide a grounding body 80 that can maintain a predetermined distance between the ejection direction control member 6 and the ground. That is, as shown in FIG. 13, the grounding body 80 is configured by a rolling element such as a wheel or a ball, a sled or the like having a low sliding resistance, and is attached to the tip of the injection direction control member 6. In addition, in the case of the injection direction control member 6 shown in FIG. 11, it can work more stably by attaching to the base part side and the front end side of the discharge part 6e.

このように構成することにより、地面と噴射方向制御部材６との間距離が一定となり、地面に向かって噴射する風力も一定となり、風向も安定させることができ、ゴミ等を拡散や散乱させることがなく、一定方向に容易に集めることができる。また、接地体８０を設けることにより、噴射方向制御部材６の重量が増加し、噴射に対する反力を抑える力を軽減できるようになる。また、地面側へ押し付ける力加減を調節する必要もない。   With this configuration, the distance between the ground and the injection direction control member 6 is constant, the wind force sprayed toward the ground is also constant, the wind direction can be stabilized, and dust and the like are diffused and scattered. It can be easily collected in a certain direction. Moreover, by providing the grounding body 80, the weight of the injection direction control member 6 increases, and the force for suppressing the reaction force against the injection can be reduced. Moreover, it is not necessary to adjust the force applied to the ground side.

以上のように、原動機となるエンジン２０と、該エンジン２０により回転駆動される送風機３０と、前記送風機３０の吐出口３５に連結され、前記送風機３０から送られる風を噴射するための噴管４０と、を具備する送風作業機１において、前記噴管４０を筒状に形成し、該噴管４０の先端には有底筒状の噴射方向制御部材６を着脱可能に取り付けることができるので、作業形態に応じて噴射方向制御部材６を選択して取り付けることができ、または、噴射方向制御部材６を外して従来と同様に真っ直ぐ噴射させることもできる。また、前記噴射方向制御部材６の側面には少なくとも一つの噴射孔６１が開口されるので、噴管４０の軸心方向に対して直角方向に噴射させることができ、壁際や段差部に沿ってゴミや落ち葉等を吹き飛ばして隅部をきれいに清掃することができるようになる。また、噴射孔６１を複数設けることで、噴射範囲を広げて略均一な風力でゴミや落ち葉等を飛ばすことができる   As described above, the engine 20 that serves as the prime mover, the blower 30 that is rotationally driven by the engine 20, and the injection pipe 40 that is connected to the discharge port 35 of the blower 30 and injects the wind sent from the blower 30. In the blower working machine 1 having the above, the tube 40 is formed in a cylindrical shape, and the bottomed tubular injection direction control member 6 can be detachably attached to the tip of the tube 40, The injection direction control member 6 can be selected and attached according to the work mode, or the injection direction control member 6 can be removed and injection can be performed straight as in the conventional case. In addition, since at least one injection hole 61 is opened on the side surface of the injection direction control member 6, the injection direction control member 6 can be injected in a direction perpendicular to the axial direction of the injection tube 40, along the wall or along the step. The corners can be cleaned cleanly by blowing off dust and fallen leaves. In addition, by providing a plurality of injection holes 61, it is possible to widen the injection range and fly dust and fallen leaves with a substantially uniform wind force.

また、前記噴射方向制御部材６には、開口面積が大きい噴射孔６１と、開口面積が小さい噴射孔６３が直径方向に対向して配置されるので、噴射孔６１からの噴射に対して反対方向に噴射孔６３から噴射され、開口面積が大きい噴射孔６１からの噴射に対する反力を軽減することができ、作業者が噴管４０を支える労力を軽減することができる。   Further, since the injection hole 61 having a large opening area and the injection hole 63 having a small opening area are arranged in the diametrical direction in the injection direction control member 6, the direction opposite to the injection from the injection hole 61. The reaction force against the injection from the injection hole 61 that is injected from the injection hole 63 and has a large opening area can be reduced, and the labor for the operator to support the injection tube 40 can be reduced.

また、前記噴射方向制御部材６の底部には風向板７０が開閉可能に設けられるので、風向板７０の角度を変更することにより噴射方向を変更することができ、作業者が噴管４０を持つ角度と地面に対する角度とに合わせて風向板７０を回動して、最も効率の良く、周囲に撒き散らさない噴射方向に調節して、作業精度を高めることができる。   Moreover, since the wind direction plate 70 is provided in the bottom part of the said injection direction control member 6 so that opening and closing is possible, an injection direction can be changed by changing the angle of the wind direction plate 70, and an operator has the jet tube 40. The airflow direction plate 70 is rotated in accordance with the angle and the angle with respect to the ground, and is adjusted to the injection direction that is most efficient and does not scatter around, thereby improving the working accuracy.

また、前記噴射方向制御部材６は折り曲げ可能に構成され、先端の吐出部６ｅの側面には軸心方向と平行に噴射孔６６・６６・・・が複数開口されるので、吐出部６ｅを地面と平行に配置して一定の幅で噴射させることができ、噴管４０を左右に振りながら作業する必要がなく、左右にゴミ等が散らばり難くなり。真っ直ぐ進むだけで一定の清掃作業ができ作業効率を向上できる。   Further, the ejection direction control member 6 is configured to be bendable, and a plurality of ejection holes 66, 66... Are opened in parallel to the axial direction on the side surface of the discharge part 6e at the tip, so that the discharge part 6e is connected to the ground. It is possible to inject with a certain width by arranging in parallel with the nozzle, and it is not necessary to work while swinging the jet tube 40 to the left and right, making it difficult for dust and the like to be scattered from side to side. A certain amount of cleaning work can be performed simply by moving straight, improving work efficiency.

また、前記噴射方向制御部材６の先端には接地体８０が設けられるので、噴射方向制御部材６と地面との間の距離を一定に保ちながら作業ができるようになり、噴射孔６１を塞いで噴射力が大きくなって噴射反力が大きくなったり、噴射方向制御部材６を地面に当てて損傷を与えたりすることがなく一定の噴射圧力で地面に吹き付けることができ、質の高い作業ができるようになる。また、接地体８０の重量により噴射反力を低減できる。   Further, since the grounding body 80 is provided at the tip of the injection direction control member 6, the work can be performed while keeping the distance between the injection direction control member 6 and the ground constant, and the injection hole 61 is blocked. The injection force is increased and the injection reaction force is increased, and the injection direction control member 6 is not applied to the ground to cause damage and can be sprayed to the ground with a constant injection pressure, so that high quality work can be performed. It becomes like this. Further, the injection reaction force can be reduced by the weight of the grounding body 80.
