The blower 5 and the engine 3 are disposed in this order on the rear side of the backpack frame 7.
A cylindrical air duct 9 extending in front of the operator is disposed at a position in the right hand direction of the operator who carries the back frame 7.
That is, the air duct 9 is formed so as to extend from the right side surface position of the backpack frame 7 and from the lower position to the front of the operator.
The blower tube 9 is partially constituted by a bellows tube 9a, and is formed so that the direction of the nozzle 11 can be changed to some extent.
The liquid tank 7 stores spraying chemicals.
A tank-side liquid feeding pipe 21 and a mixing part-side liquid feeding pipe 23 for pressure-feeding the chemical solution from the liquid tank 7 are disposed along the blower pipe 9.
Between the tank side liquid supply pipe 21 and the mixing section side liquid supply pipe 23, a cock 17 for turning ON / OFF the supply of the liquid supply is disposed.

エンジン３によって生じた駆動力によって送風機５が回転する。
送風機５の回転数は、ハンドル３３に形成されたスロットルレバー１５によって制御される。また、このハンドル３３が送風管９に取り付けられている位置の近傍にスロットルレバー１５が取り付けられている。
なお、本実施形態では、エンジン３によって送風機５は駆動されるが、エンジン３に限る趣旨ではなく、モータ等によって送風機５が駆動されてもよい。 The blower 5 is rotated by the driving force generated by the engine 3.
The rotational speed of the blower 5 is controlled by a throttle lever 15 formed on the handle 33. Further, the throttle lever 15 is attached in the vicinity of the position where the handle 33 is attached to the blower tube 9.
In the present embodiment, the blower 5 is driven by the engine 3, but is not limited to the engine 3, and the blower 5 may be driven by a motor or the like.

背負枠７には、貫通穴７ａが形成されている。背負枠７の前面７ｄ側にある空気はこの貫通穴７ａを通過して、送風機５に吸い込まれる。   A through hole 7 a is formed in the back frame 7. Air on the front surface 7 d side of the backpack 7 passes through the through hole 7 a and is sucked into the blower 5.

この背負枠７の前面７ｄには、背当部材８が配設される。より具体的には、背負枠７の前面７ｄに背当部材８が装着される（背当部材８の詳細について、図４についての説明も参照のこと）。
背当部材８には、クッションの機能を果たすために弾性を有する複数の背当パッド８０を有する。
そして、複数の背当パッド８０は、間隔（縦間隔８ａ、横間隔８ｂ）を有して配設されている。
この背当パッド８０は、左側肩部材８１、右側肩部材８３、腰部材８５、シート８９及びシート８７を有する。
この左側肩部材８１及び右側肩部材８３と、腰部材８５との間に形成される横間隔８ｂは、水平方向に延びている。
この左側肩部材８１と右側肩部材８３との間に形成される縦間隔８ａは、鉛直方向に延びている。
腰部材８５は、作業者の腰及び臀部の上側に対応する位置に当接する。 A backrest member 8 is disposed on the front surface 7d of the backpack frame 7. More specifically, the backrest member 8 is mounted on the front surface 7d of the backpack frame 7 (see also the description of FIG. 4 for details of the backrest member 8).

A vertical interval 8a formed between the left shoulder member 81 and the right shoulder member 83 extends in the vertical direction.
The waist member 85 is in contact with a position corresponding to the upper side of the operator's waist and buttocks.

図２は、ミストブロワ１の空気流及び薬液の流れの説明図である。   FIG. 2 is an explanatory diagram of the air flow and the chemical flow of the mist blower 1.

図２のように、送風機５の回転によって、ミストブロワ１の周囲に存在する空気が取り込まれ、空気の流れ（空気流）となって送風機５から送出される。
より具体的には、エンジン３によって生み出された回転力によって、遠心ファン５ａが回転する。この遠心ファン５ａの回転によって、背当部材８及び背負枠７の貫通穴７ａを通過した空気、及び、背負枠７の後面７ｃと送風機５との間の空間から吸いこまれる空気が送風機５に吸い込まれる。
この送風機が、周囲の空気を吸い込む際には、これらの空気は空気吸入口５ｂを通過する。この空気吸入口５ｂはドーム状の形状で、複数の穴が形成されている。つまり、この複数の穴が形成されることによって、網目状の柵が形成されておいることになる。
空気吸入口５ｂは、換言すると、ざる（Sieve）の様な形状を有している。
この空気吸入口５ｂが網目状の柵を有する形状を有しているのは、送風機５が周囲の木の葉などを吸い込んでしまうことを防ぐためである。
また、ドーム状の形状を有するのは、空気吸入口５ｂに付着してしまった木の葉などを取り除くのを容易にするためである。 As shown in FIG. 2, the air around the mist blower 1 is taken in by the rotation of the blower 5, and is sent from the blower 5 as an air flow (air flow).
More specifically, the centrifugal fan 5 a is rotated by the rotational force generated by the engine 3. By the rotation of the centrifugal fan 5a, the air that has passed through the through hole 7a of the backrest member 8 and the backpack 7 and the air sucked from the space between the rear surface 7c of the backpack 7 and the blower 5 are sucked into the blower 5. It is.
When this blower sucks in ambient air, these air passes through the air inlet 5b. The air inlet 5b has a dome shape and is formed with a plurality of holes. That is, a mesh-shaped fence is formed by forming the plurality of holes.
In other words, the air inlet 5b has a shape like Sieve.
The reason why the air inlet 5b has a shape having a mesh-like fence is to prevent the blower 5 from sucking in the leaves of surrounding trees.
Further, the reason for having a dome shape is to make it easier to remove leaves or the like adhering to the air inlet 5b.

またこの、空気吸入口５ｂの形状に対応するように、背負枠７の後面７ｃにも窪み部７ｂが形成されている。この窪み部７ｂによって、ドーム状を有する空気吸入口５ｂに背負枠７の後面７ｃと送風機５との間の空間からの空気が効率よく吸入される。   A recess 7b is also formed on the rear surface 7c of the back frame 7 so as to correspond to the shape of the air inlet 5b. Air from the space between the rear surface 7c of the backpack frame 7 and the blower 5 is efficiently sucked into the air suction port 5b having a dome shape by the recess 7b.

遠心ファン５ａの回転によって背当部材８及び背負枠７の貫通穴７ａを通過する空気は、以下の３つの経路で貫通穴７ａに流入する。
（１） 背当部材８の両サイドの空気が、背当部材８の左側肩部材８１及び右側肩部材８３と腰部材８５との間に形成された横間隔８ｂを通過して流入する。
（２） 背当部材８の上方の空気が、左側肩部材８１と右側肩部材８３との間の縦間隔８ａを通過して流入する（図１及び図４も参照のこと）。
（３） 作業者の背面にある空気が、シート８９を貫通して、横間隔８ｂ及び縦間隔８ａを経過して流入する。 The air passing through the through hole 7a of the backrest member 8 and the back frame 7 by the rotation of the centrifugal fan 5a flows into the through hole 7a through the following three paths.
(1) The air on both sides of the backrest member 8 flows in through the left shoulder member 81 of the backrest member 8 and the lateral distance 8b formed between the right shoulder member 83 and the waist member 85.
(2) The air above the backrest member 8 flows through the vertical interval 8a between the left shoulder member 81 and the right shoulder member 83 (see also FIGS. 1 and 4).
(3) The air on the back of the operator passes through the seat 89 and flows in after passing through the horizontal interval 8b and the vertical interval 8a.

送風機５から送出された空気の流れは送風管９のエルボ部分９ｂに送られ、この送風管９を流れる。送風管９は、前述のように、蛇腹管９ａ及びハンドル３３を有する。
他方では、薬液を加圧送出するための空気の流れは加圧管１９及び液タンク内加圧管２５を介して液タンク７に送られる。なお、加圧管１９及び液タンク内加圧管２５を液タンク７に挿入する部分にはタンクグロメット２９が形成されており、液タンク７を密閉状態に保っている（図３も参照のこと）。
液タンク７内の液タンク内加圧管２５の端部位置に分岐部３１が形成される。
この分岐部３１は、空気を２つ以上に分岐させて液タンク７内部に放出する。
タンク側送液管２１の開口部２１ａは液タンク７の底面若しくは底面付近に配設され、液タンク７内に貯蔵された薬液はタンク側送液管２１及び混合部側送液管２３を介して混合部１３へ圧送される。
混合部側送液管２３を圧送された薬液の流れは、混合部１３内の混合部側送液管２３の混合部側開口部２３ａから、ディフューザ構造のディフューザ部１３ａに放出される。
そして、このディフューザ部１３ａにおいて、送風管９内を流れてきた空気の流れと混合し霧状となり、薬液がミストとしてノズル１１から送出される。
換言すると、このノズル１１では、空気の流れと薬液の流れが混ざった混合流として送出される。 The flow of air sent from the blower 5 is sent to the elbow portion 9 b of the blower tube 9 and flows through this blower tube 9. As described above, the blower tube 9 includes the bellows tube 9a and the handle 33.
On the other hand, the air flow for pressurizing and sending the chemical solution is sent to the liquid tank 7 via the pressurizing pipe 19 and the liquid tank pressurizing pipe 25. A tank grommet 29 is formed at a portion where the pressurizing pipe 19 and the liquid tank pressurizing pipe 25 are inserted into the liquid tank 7, and the liquid tank 7 is kept in a sealed state (see also FIG. 3).
A branch portion 31 is formed at the end position of the pressure tank 25 in the liquid tank 7 in the liquid tank 7.
This branch part 31 branches the air into two or more and discharges it into the liquid tank 7.
The opening 21a of the tank side liquid feeding pipe 21 is disposed at or near the bottom surface of the liquid tank 7, and the chemical solution stored in the liquid tank 7 passes through the tank side liquid feeding pipe 21 and the mixing part side liquid feeding pipe 23. And fed to the mixing unit 13 by pressure.
The flow of the chemical solution pumped through the mixing unit side liquid feeding pipe 23 is discharged from the mixing unit side opening 23a of the mixing unit side liquid feeding pipe 23 in the mixing unit 13 to the diffuser portion 13a having the diffuser structure.
And in this diffuser part 13a, it mixes with the flow of the air which flowed in the inside of the ventilation pipe | tube 9, becomes a mist form, and a chemical | medical solution is sent out from the nozzle 11 as mist.
In other words, in this nozzle 11, it sends out as a mixed flow with which the flow of air and the flow of the chemical | medical solution were mixed.

図３は、液タンク７の断面の説明図である。   FIG. 3 is an explanatory view of a cross section of the liquid tank 7.

液タンク７は、キャップ２７によって密閉される。
キャップ２７は、螺着によって液タンク７に固定される。また、キャップ２７が取り外されることによって、作業者は液タンク７内に薬液の補給が可能である。
加圧管１９は液タンク７に装着されるタンクグロメット２９に接続され、液タンク内加圧管２５は、液タンク７内でタンクグロメット２９に接続される。
タンクグロメット２９は、加圧管１９及び液タンク内加圧管２５によって運ばれる空気を液タンク７内に導入する機能、及び、液タンク７を密閉状態に保つ機能を有している。
そして、液タンク内加圧管２５はホースで形成され、液タンク７内を上方から下方に延びている。
そして、液タンク内加圧管２５の終端部には分岐部３１が配設され、この分岐部３１は液タンク７の下部に位置する。
液タンク内加圧管２５を介して送られた空気は、薬液の内部で分岐部３１から空気を放出することによって薬液を撹拌している。 The liquid tank 7 is sealed with a cap 27.
The cap 27 is fixed to the liquid tank 7 by screwing. Further, by removing the cap 27, the operator can replenish the liquid chemical in the liquid tank 7.
The pressurizing pipe 19 is connected to a tank grommet 29 attached to the liquid tank 7, and the liquid tank pressurizing pipe 25 is connected to the tank grommet 29 in the liquid tank 7.
The tank grommet 29 has a function of introducing air carried by the pressurization pipe 19 and the liquid tank pressurization pipe 25 into the liquid tank 7 and a function of keeping the liquid tank 7 in a sealed state.
The pressure tank 25 in the liquid tank is formed of a hose and extends from the top to the bottom in the liquid tank 7.
A branch portion 31 is disposed at the end of the pressure tank 25 in the liquid tank, and the branch portion 31 is located below the liquid tank 7.
The air sent through the pressure tank 25 in the liquid tank agitates the chemical liquid by releasing the air from the branch part 31 inside the chemical liquid.

液タンク７のほぼ中心位置には、貫通穴７ａが掲載されており、この貫通穴７ａの裏側方向には空気吸入口５ｂが位置している。
また、図３のように、貫通穴７ａは、横方向の長さよりも縦方向の長さが長く形成されている。 A through hole 7a is provided at a substantially central position of the liquid tank 7, and an air suction port 5b is located in the back side direction of the through hole 7a.
Further, as shown in FIG. 3, the through hole 7a has a length in the vertical direction longer than a length in the horizontal direction.

図４のＡ図〜図４のＣ図のように、背当部材８には、クッションの機能を果たすために弾性を有する複数の背当パッド８０を有する。   As shown in FIG. 4A to FIG. 4C, the back support member 8 has a plurality of back contact pads 80 having elasticity in order to function as a cushion.

左側肩部材８１、右側肩部材８３及び腰部材８５はシート８７にそれぞれ接続されている。より具体的には、左側肩部材８１、右側肩部材８３及び腰部材８５はシート８７に縫込み、接着等で接続されている。
このため、左側肩部材８１、右側肩部材８３及び腰部材８５はシート８７との接続は、通常の使用等では分離不能に形成される。もっとも、左側肩部材８１、右側肩部材８３及び腰部材８５と、シート８７との接続は面ファスナー（パイルアンドフック）、ボタン、フック、等で、脱着可能としてもよい。
左側肩部材８１、右側肩部材８３及び腰部材８５はシート８９にも、それぞれ接続される。
腰部材８５はシート８９との接続は、縫込み、接着等で接続される。もっとも、腰部材８５と、シート８９との接続は面ファスナー（パイルアンドフック）、ボタン、フック、等で、脱着可能とすることも可能である。
他方、左側肩部材８１とシート８９との間の接続面は、左側肩部材８１側に面ファスナーの左側一方８１ａを設け、シート８９に面ファスナーの左側他方８９ａＬを設けることによって、脱着可能に形成される。
また、右側肩部材８３とシート８９との間の接続面は、右側肩部材８３側に面ファスナーの右側一方８３ａを設け、シート８９に面ファスナーの右側他方８９ａＲを設けることによって、脱着可能に形成される。
なお、面ファスナー（パイルアンドフック）は、ボタン、フック、等で、容易に脱着可能に形成されるものに置換可能である。
また、以上の例では、シート８９は、腰部材８５に脱着不能に、左側肩部材８１及び右側肩部材８３に脱着可能としていたが、腰部材８５に脱着可能に、左側肩部材８１及び右側肩部材８３に脱着不能としても、両方に対して脱着可能であっても良い。 The left shoulder member 81, the right shoulder member 83, and the waist member 85 are connected to the seat 87, respectively. More specifically, the left shoulder member 81, the right shoulder member 83, and the waist member 85 are connected to the seat 87 by sewing, bonding, or the like.
For this reason, the left shoulder member 81, the right shoulder member 83, and the waist member 85 are formed so as to be inseparable from each other in normal use or the like. However, the connection between the left shoulder member 81, the right shoulder member 83, the waist member 85, and the seat 87 may be detachable with a hook-and-loop fastener (pile and hook), a button, a hook, and the like.
The left shoulder member 81, the right shoulder member 83, and the waist member 85 are also connected to the seat 89, respectively.
The waist member 85 is connected to the seat 89 by sewing, bonding or the like. However, the connection between the waist member 85 and the seat 89 can be made detachable with a hook-and-loop fastener (pile and hook), a button, a hook, and the like.
On the other hand, the connection surface between the left shoulder member 81 and the seat 89 is detachable by providing the left one 81a of the surface fastener on the left shoulder member 81 side and the left other 89aL of the surface fastener on the seat 89. Is done.
Further, the connection surface between the right shoulder member 83 and the seat 89 is formed to be detachable by providing the right one 83a of the hook-and-loop fastener on the right shoulder member 83 side and the right other 89aR of the hook-and-loop fastener on the seat 89. Is done.
Note that the hook-and-loop fastener (pile and hook) can be replaced with a button, hook, or the like that can be easily detached.
In the above example, the seat 89 cannot be attached to or detached from the waist member 85 but can be attached to or removed from the left shoulder member 81 and the right shoulder member 83. Even if the member 83 is not removable, the member 83 may be removable.

シート８９及びシート８７は、貫通方向に通風性をよくするためにメッシュ状の形状を有した布地で形成される。もっとも、通風性が高ければメッシュ形状に限る趣旨ではない。また、シート８７のメッシュ形状は必須ではない。
シート８７には、シート８７を背負枠７に装着した時、貫通穴７ａに該当する位置に貫通穴８７ａが形成されている。
なお、複数の背当パッド８０及びシート８９は熱伝達率が高く、水の吸収率が高い方が作業者に清涼感をより与えることが可能であり好適である。
また、腰部材８５は、図４のＡ図のように、下方に行くほど前後方向の厚さが薄くなるように形成されているが、これは、作業者の臀部が張り出してくるため、背負い心地を良く、これに合わせるためである。 The sheet 89 and the sheet 87 are formed of a fabric having a mesh shape in order to improve air permeability in the penetration direction. However, if the air permeability is high, the purpose is not limited to the mesh shape. Further, the mesh shape of the sheet 87 is not essential.
A through hole 87 a is formed in the sheet 87 at a position corresponding to the through hole 7 a when the seat 87 is mounted on the back frame 7.
The plurality of back pad 80 and the seat 89 have a high heat transfer rate, and a higher water absorption rate is more preferable because it can give the operator a refreshing feeling.
Further, as shown in FIG. 4A, the waist member 85 is formed so that the thickness in the front-rear direction becomes thinner as it goes downward, but this is because the operator's buttocks overhang. This is because it is comfortable and fits this.

また、背当部材８には、背当部材８を背負枠７に取り付けるための、取付孔８７ｂが、右側上方位置、左側上方位置及び中央下方位置に設けられている。
背当部材８は、シート８９が表面となるように、シート８７を背負枠７の前面７ｄに装着し、取付孔８７ｂで背負枠７にねじ止めされる。 The back support member 8 is provided with attachment holes 87b for attaching the back support member 8 to the backpack frame 7 at the upper right position, the upper left position, and the lower center position.
The backrest member 8 is mounted on the front surface 7d of the backpack 7 so that the seat 89 is the front surface, and is screwed to the backpack 7 through the mounting hole 87b.

以上のように構成したこと、つまり、作業者側にメッシュ状のシート８９を形成したことから、送風機５の空気吸入口５ｂとの距離が離れて、作業者の衣類等を吸い込むことを十分に防ぐことが可能となる。
また、以上のように構成したことから、背当部材８の縦間隔８ａ及び横間隔８ｂを通じて、空気が常に流れることから、常に、作業者に清涼感を与えることができる。
特に、熱の籠りやすい、背骨の周りの部分に縦間隔８ａ及び腰部分に横間隔８ｂが形成されることから、作業者の汗等を蒸発させることが可能となる。
また、シート８９も貫通方向に通風性が高いことから、直接、作業者に触れる風を取り込むことができ、作業者の汗を蒸発させることができる。 Since the mesh-shaped sheet 89 is formed on the worker side as described above, the distance from the air suction port 5b of the blower 5 is increased, and the worker's clothing and the like are sufficiently sucked. It becomes possible to prevent.
Moreover, since it has comprised as mentioned above, since air always flows through the vertical interval 8a and the horizontal interval 8b of the backrest member 8, a refreshing feeling can always be given to an operator.
In particular, since the vertical interval 8a and the horizontal interval 8b are formed in the portion around the spine where heat is easily generated, the sweat of the operator can be evaporated.
Further, since the sheet 89 also has high air permeability in the penetrating direction, it is possible to take in the wind directly touching the worker and evaporate the sweat of the worker.

図５は、ミストブロワ１の空気吸入口５ｂを作業者が掃除する状況の説明図であり、ミストブロワ１を前後方向かつ垂直に切った断面図である。   FIG. 5 is an explanatory view of a situation where an operator cleans the air inlet 5b of the mist blower 1, and is a cross-sectional view of the mist blower 1 cut in the front-rear direction and perpendicularly.

上述のように、右側肩部材８３の面ファスナーの右側一方８３ａとシート８９の面ファスナーの右側一方８９ａＲとは工具を使用することなく脱着可能である。
また、貫通穴７ａは、横方向の長さよりも縦方向の長さが長く形成されている。これによって、作業者はそのまま手首をねじらずに、貫通穴７ａに手を容易に挿入することが可能となる。
さらに、縦方向に長いため、作業者はかがんで貫通穴７ａの高さに目線を合わせなくても、貫通穴７ａを通して空気吸入口５ｂを視認することが容易になる。
このため、送風機５の空気吸入口５ｂに木の葉などが付着しても、背当部材８の側からドーム状の空気吸入口５ｂを容易に清掃できる。 As described above, the right side 83a of the surface fastener of the right shoulder member 83 and the right side 89aR of the surface fastener of the seat 89 can be detached without using a tool.
Moreover, the through-hole 7a is formed so that the length in the vertical direction is longer than the length in the horizontal direction. As a result, the operator can easily insert his / her hand into the through hole 7a without twisting his wrist.
Furthermore, since it is long in the vertical direction, it is easy for an operator to visually recognize the air inlet 5b through the through hole 7a without bending and aligning the line of sight with the height of the through hole 7a.
For this reason, even if leaves or the like adhere to the air suction port 5b of the blower 5, the dome-shaped air suction port 5b can be easily cleaned from the backrest member 8 side.
