Description

この発明は、園芸若しくは農業用薬液又は除草剤の散布作業、潅水作業、工業用薬液塗布作業又は洗浄作業等に使用される蓄圧型噴霧器についての技術である。   The present invention relates to a pressure accumulating sprayer used for horticultural or agricultural chemicals or herbicide spraying work, irrigation work, industrial chemical application or cleaning work, and the like.

従来の噴霧器には、図６に示すようなものがあり、該噴霧器では、噴霧作業を行い内部の液体が減り液体の水位が下降すると、圧力タンク１０１の重心が液体貯留室１０５の底面へ向かって徐々に移動して行く特徴を持っている。
一方で圧力タンク１０１からノズル１０８への噴霧液体の圧送は、内蔵した手動ポンプ１０２を利用して液体貯留室１０５の上部に位置する単体の気体蓄圧室１０６へ気体を送りこみ、タンク内圧を上昇させることにより行っていた。 FIG. 6 shows a conventional sprayer. In the sprayer, when the spraying operation is performed and the internal liquid is reduced and the liquid level is lowered, the center of gravity of the pressure tank 101 is directed toward the bottom surface of the liquid storage chamber 105. It has a feature that moves gradually.
On the other hand, the spray liquid is pumped from the pressure tank 101 to the nozzle 108 by using the built-in manual pump 102 to send the gas into the single gas accumulating chamber 106 located above the liquid storage chamber 105 to increase the tank internal pressure. It was done by letting.

一般に、噴霧器の圧力タンクを背負う場合には、かなりの重量があることから圧力タンクを垂直に立てると前記タンクの全重量が背負うためのバンド１０７を介して作業者の両肩に集中して疲れてしまう。従って作業者は、腰の位置と略同じ高さ以上の背中で負荷を受けるように圧力タンクの上部を若干前傾させるように背負う（図３参照）と考えられる。しかし、噴霧器の圧力タンクは、液体貯留室の底面が該タンクの低い位置に形成されていため、液体が減少すると、重心が作業者の腰位置より低いところへ移動し、腰の位置を支点とした「てこの作用」が働くこととなる。このとき作業者の両肩は、前記バンドを介して後ろへ引っ張られ、支点となる腰には負荷が集中することにより作業者が疲れてしまうという第１の問題が有った。   Generally, when the pressure tank of the sprayer is carried on the back, there is a considerable weight, so when the pressure tank is set up vertically, the entire weight of the tank is concentrated on both shoulders of the operator through the band 107 for carrying the back. End up. Therefore, it is considered that the operator carries the back so that the upper part of the pressure tank is tilted slightly forward so as to receive a load with a back having a height substantially equal to or higher than the waist position (see FIG. 3). However, the pressure tank of the nebulizer has the bottom surface of the liquid storage chamber formed at a low position of the tank.If the liquid decreases, the center of gravity moves to a position lower than the operator's waist position, and the waist position is used as a fulcrum. The “leverage action” will work. At this time, both the shoulders of the operator were pulled back through the band, and there was a first problem that the operator was tired because the load was concentrated on the waist serving as a fulcrum.

また、従来の圧力タンクの気体畜圧室は、噴霧する液体上部と圧力タンク上部内壁に囲まれたスペースに限定して形成されていたため、噴霧作業前に前記圧力タンクの内部を液体で満杯にした状態において、形成される気体蓄圧室の体積は小さかった。 従って、密閉された気体蓄圧室の内圧と体積の積も小さかったため、前記圧力タンクの内圧は、噴霧により気体蓄圧室の体積が増加するにつれて、高い割合で減少していた（ボイルの法則より密封状態では内圧Ｐ、体積ＶとするとＰＶ＝一定となる）。即ち、満杯にした液体を全て噴霧し終わるまで前記圧力タンクの内圧が大きく低下するという第２の問題が有った。   In addition, the gas pressure chamber of the conventional pressure tank is formed only in the space surrounded by the upper part of the liquid to be sprayed and the inner wall of the upper part of the pressure tank, so that the inside of the pressure tank is filled with liquid before the spraying operation. In this state, the volume of the gas pressure accumulating chamber formed was small. Accordingly, since the product of the internal pressure and volume of the sealed gas accumulator chamber was small, the internal pressure of the pressure tank decreased at a higher rate as the volume of the gas accumulator chamber increased by spraying (by sealing from Boyle's law). In the state, when the internal pressure is P and the volume is V, PV becomes constant). That is, there has been a second problem that the internal pressure of the pressure tank is greatly reduced until all of the filled liquid is sprayed.

また、図６のように内圧上昇用の手動ポンプ１０２を内蔵する従来の圧力タンクでは、ポンプハンドル１０２ａを上下させるストロークを設けるため、ポンプの外筒１０２ｂを噴霧液体の中まで伸張することから、結果として気体出口１０３は噴霧する液体の中に設けられることが多い。しかし、送り込まれた気体が噴霧する液体の中を通過すると、前記圧力タンク内部に気泡が発生し、泡立つことになる。このような泡立ちの発生は、噴霧の最後に悪影響を与えるという第３の問題が有った。   Further, in the conventional pressure tank incorporating the manual pump 102 for increasing the internal pressure as shown in FIG. 6, the pump outer cylinder 102b is extended into the spray liquid to provide a stroke for raising and lowering the pump handle 102a. As a result, the gas outlet 103 is often provided in the liquid to be sprayed. However, when the fed gas passes through the sprayed liquid, bubbles are generated inside the pressure tank and foamed. The occurrence of such bubbling has a third problem of adversely affecting the end of spraying.

以上に記載した問題に鑑み、本発明の目的は、噴霧作業を行うに際して作業者が疲れにくく、安定した噴霧作業が可能となる噴霧器の技術を提供することにある。   In view of the problems described above, an object of the present invention is to provide a sprayer technology that makes it difficult for an operator to get tired when performing a spraying operation and enables a stable spraying operation.

以下に請求項１〜５までに記載された発明の効果をそれぞれ説明する。
請求項１の発明では、圧力タンク内部が仕切板により分割され、仕切板上方には仕切板上面を底面とした液体貯留室が画成される一方で、前記仕切板の下方には、第１の気体蓄圧室が画成されているため、噴霧する液体が減少しても圧力タンクの重心は仕切板より上に保持される。即ち、従来の圧力タンクと比較して重心が上にくる。 The effects of the invention described in claims 1 to 5 will be described below.
According to the first aspect of the present invention, the inside of the pressure tank is divided by the partition plate, and a liquid storage chamber having a partition plate upper surface as a bottom surface is defined above the partition plate. Since the gas accumulator chamber is defined, the center of gravity of the pressure tank is maintained above the partition plate even if the amount of liquid to be sprayed is reduced. That is, the center of gravity is higher than the conventional pressure tank.

更に請求項１の発明では、圧力タンクの液体貯留室上部に設けられた気体蓄圧室（ここでは第２の気体蓄圧室としている）に加えエアーパイプで連通し、第２の気体蓄圧室と同圧に維持される第１の気体蓄圧室を液体貯留室の下に設けてある。従って、噴霧開始前であって圧力タンク内部を液体で満杯にした状態であっても、従来の圧力タンクに比べて、第１と第２の気体蓄圧室の体積を合わせると、全体として大きなものとなっている。従って、従来の気体蓄圧室と同じ内圧に加圧した場合でも、気体蓄圧室の体積と内圧の積は従来のものに比べて大きいことから、噴霧作業による体積の増加と比較した圧力低下の割合が、従来より小さくなり（ボイルの法則より）、内圧はゆっくりと低下する。即ち、満杯にした液体を全て噴霧し終わるまでに起きる前記圧力タンクの大きな内圧低下が抑制される。   Further, according to the first aspect of the present invention, in addition to the gas pressure storage chamber (in this case, the second gas pressure storage chamber) provided in the upper part of the liquid storage chamber of the pressure tank, it communicates with an air pipe and is the same as the second gas pressure storage chamber. A first gas accumulator chamber maintained at a pressure is provided below the liquid reservoir chamber. Therefore, even if the pressure tank is filled with liquid before the start of spraying, the total volume of the first and second gas accumulator chambers is larger than that of the conventional pressure tank. It has become. Therefore, even when pressurized to the same internal pressure as the conventional gas accumulator chamber, the product of the volume of the gas accumulator chamber and the internal pressure is larger than the conventional one, so the rate of pressure drop compared to the increase in volume due to spraying However, it becomes smaller than before (by Boyle's law), and the internal pressure decreases slowly. In other words, a large drop in the internal pressure of the pressure tank that occurs until all of the full liquid is sprayed is suppressed.

請求項２の発明では、圧力タンクを背負った作業者の腰と略同じ高さ以上の位置に仕切板がくるように取り付けることで前述した「てこの作用」を防止できることから、前記圧力タンクを背負う者の肩と腰にかかる負荷が軽減されることとなる。   In the invention of claim 2, the above-mentioned “leverage action” can be prevented by attaching the partition plate so that the partition plate comes to a position approximately equal to or higher than the waist of the worker carrying the pressure tank. The load on the shoulder and waist of the person carrying the back will be reduced.

請求項３の発明では、圧力タンクの第１及び第２の気体蓄圧室は中空状のエアーパイプを介して空気孔より連通することで両気体蓄圧室の内圧は、同圧に保たれる。また、従来の気体出口に当たる気体導入口は、噴霧する液体中でなく第１の気体蓄圧室に直接連通している。従って、送り込まれる気体は、噴霧する液体の中を通過せず、前記圧力タンク内部における泡立ちが防止され、安定した噴霧作業が可能となる。また、前記第２の気体蓄圧室には、連通するエアーパイプ内に逆止バルブが設けられることで気体が第１の気体畜圧室へ流れることがある程度抑制される。従って、前記第２の気体蓄圧室においては、作業中に前記圧力タンクが振動することで噴霧する液体の液面が上下しても、内圧の乱れが抑制される。   In the invention of claim 3, the first and second gas pressure accumulating chambers of the pressure tank communicate with each other through the air holes via the hollow air pipe, so that the internal pressures of both gas accumulating chambers are maintained at the same pressure. In addition, the gas inlet corresponding to the conventional gas outlet communicates directly with the first gas pressure accumulating chamber, not in the liquid to be sprayed. Therefore, the gas to be fed does not pass through the liquid to be sprayed, foaming inside the pressure tank is prevented, and a stable spraying operation is possible. The second gas accumulator chamber is provided with a check valve in the communicating air pipe, so that the flow of gas to the first gas accumulator chamber is suppressed to some extent. Therefore, in the second gas accumulator chamber, even if the liquid level of the sprayed liquid rises and falls due to the vibration of the pressure tank during the operation, the disturbance of the internal pressure is suppressed.

請求項４の発明では、エアーポンプを取り外し可能な外付けの別部品とすることで、圧力タンクがより軽量化され、圧力タンクを背負う際の作業者の負担が軽減される。また、気体導入口には手動式又はエアーコンプレッサー等の様々なエアーポンプを取り付けることが出来るため、汎用ポンプをコストに応じて自由に準備して使用することが出来る。   In the invention of claim 4, the pressure tank is further reduced in weight by making the air pump a separate external part that can be removed, and the burden on the operator when carrying the pressure tank is reduced. Moreover, since various air pumps, such as a manual type or an air compressor, can be attached to a gas inlet, a general purpose pump can be freely prepared according to cost and used.

請求項５の発明は、噴霧器を使用する者の選択により、圧力タンクを背負って噴霧作業をするだけでなく、該圧力タンクを背負わずにキャリヤーに載せて噴霧作業を行うことが出来る。従って、噴霧作業時に前記圧力タンクをキャリヤーに搭載すれば、噴霧器を使用する者の肩、背中及び腰への負担が大きく解消される。一方、前記圧力タンクをキャリヤーに搭載すれば、噴霧作業時に移動がし易く、小回りも効くことで移動範囲と噴霧範囲を広げることが出来るため、作業目的に応じて広範囲にわたる噴霧作業を行うことが出来る。   According to the invention of claim 5, not only can the pressure tank be carried on the back, but also the spray work can be carried on the carrier without carrying the pressure tank, depending on the choice of the person using the sprayer. Therefore, if the pressure tank is mounted on the carrier during the spraying operation, the burden on the shoulder, back and waist of the person using the sprayer is greatly eliminated. On the other hand, if the pressure tank is mounted on the carrier, it is easy to move during spraying work, and the range of movement and spraying range can be expanded by having a small turn, so that a wide range of spraying work can be performed according to the work purpose. I can do it.

以上より本発明の噴霧器は、従来のものに比べて作業者の作業負担が少ないために噴霧作業をしても疲れにくく、安定した噴霧作業が可能なものとなっている。   As described above, the sprayer according to the present invention has less work burden on the operator as compared with the conventional one, so that it is difficult to get tired even when spraying and stable spraying is possible.

以下、図面１〜６を参照して本願発明の好適な実施形態について説明する。
図１は実施形態１にかかる噴霧器の構造を表す一部断面側面図、図２（ａ）は実施形態１及び２におけるエアーパイプの上端部及び液体投入口近傍の内部構造を表す断面図、同図（ｂ）は実施形態１及び２におけるエアーパイプの下端部の固定の状態を表す断面図、図３は実施形態１の噴霧器を使用した状態を表す参考図、図４は実施形態２の噴霧器を表す側面図、図５は実施形態２の噴霧器を使用した状態を表す参考図、図６は従来技術を表す一部断面側面図である。 Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS.
FIG. 1 is a partial cross-sectional side view showing the structure of a sprayer according to Embodiment 1, and FIG. 2A is a cross-sectional view showing the internal structure near the upper end of the air pipe and the liquid inlet in Embodiments 1 and 2. FIG. 4B is a cross-sectional view showing a fixed state of the lower end portion of the air pipe in the first and second embodiments, FIG. 3 is a reference diagram showing a state in which the sprayer of the first embodiment is used, and FIG. FIG. 5 is a reference view showing a state in which the sprayer of Embodiment 2 is used, and FIG. 6 is a partial cross-sectional side view showing the prior art.

まず図１により実施形態１における噴霧器の概要を説明すると、この噴霧器は、主として圧力タンク１、該タンクの外周壁に取り付けられた複数の背負バンド１０（本実施形態では２本とする）及び噴霧ノズル８から構成されている。ここで図１より圧力タンク１の内部は、底板１ｄと平行な仕切板１ｃを底板１ｄの上方に設けることにより該タンク内部が、上下２つの領域に分割されており、仕切り板１ｃの上には、噴霧する液体を貯留する液体貯留室１２と、噴霧する液体に上方から圧力をかける第２の気体蓄圧室１３ｂが形成されている。一方、仕切板１ｃの下には、第１の気体蓄圧室１３ａが形成される。   First, the outline of the sprayer according to Embodiment 1 will be described with reference to FIG. 1. This sprayer mainly includes a pressure tank 1, a plurality of back strap bands 10 (two in this embodiment) attached to the outer peripheral wall of the tank, and a spray. It consists of a nozzle 8. Here, as shown in FIG. 1, the inside of the pressure tank 1 is divided into two upper and lower areas by providing a partition plate 1c parallel to the bottom plate 1d above the bottom plate 1d. Are formed with a liquid storage chamber 12 for storing the liquid to be sprayed and a second gas accumulator chamber 13b for applying pressure from above to the liquid to be sprayed. On the other hand, a first gas pressure accumulation chamber 13a is formed under the partition plate 1c.

尚、仕切板１ｃ及び背負いバンド１０は、使用者の体型を考慮し、背負ったときに仕切板１ｃが該使用者の腰の位置と略同じ高さ以上の位置に取り付けるようにする。   In consideration of the user's body shape, the partition plate 1c and the back strap 10 are attached to a position that is substantially equal to or higher than the position of the user's waist when the back plate is carried.

また、図２（ａ）に示すように、中空状のエアーパイプ１７ａの上端部は、中空状の取付金具１７ｃの下端と継合し、フランジ状に形成された取付金具１７ｃの上端部が、圧力タンク上部１ｂに設けられた貫通孔に固定されている。そして前記上端部の側面には、複数の（本実施形態では２つ）の空気孔１７ｂが設けられることにより、エアーパイプ１７ａの内部と第２の気体蓄圧室１３ｂとが連通する。一方図２（ｂ）に示すようにエアーパイプ１７ａの下端部は、仕切板１ｃの中央に設けられた貫通孔に嵌合し、第１の気体蓄圧室１３ａとエアーパイプ１７ａの内部が連通する。
また、仕切板１ｃ及び背負いバンド１０の取り付け位置は想定する使用者の身長に応じて、背負ったときに仕切板１ｃが腰の位置と略同じ高さ以上となるように（図３を参照）配置する。尚、図２（ａ）（ｂ）の１９に示すように、取付金具１７ｃと圧力タンク上面１ｂ及びエアーパイプ１７ａとの固定並びに仕切板１ｃとエアーパイプ１７ａ及び圧力タンク胴部１ａとの固定においては、密閉性と内圧に対する強度を考慮して、例えば各周縁部１９には溶接処理を施すこととする。 As shown in FIG. 2A, the upper end of the hollow air pipe 17a is joined to the lower end of the hollow mounting bracket 17c, and the upper end of the mounting bracket 17c formed in a flange shape is It is being fixed to the through-hole provided in the pressure tank upper part 1b. A plurality (two in this embodiment) of air holes 17b are provided on the side surface of the upper end portion, so that the inside of the air pipe 17a communicates with the second gas pressure accumulation chamber 13b. On the other hand, as shown in FIG. 2B, the lower end portion of the air pipe 17a is fitted into a through hole provided in the center of the partition plate 1c, and the first gas pressure accumulating chamber 13a and the inside of the air pipe 17a communicate with each other. .
Further, the mounting positions of the partition plate 1c and the back strap 10 are set so that the partition plate 1c is substantially equal to or higher than the waist position when it is carried according to the assumed height of the user (see FIG. 3). Deploy. 2A and 2B, the fixing bracket 17c is fixed to the pressure tank upper surface 1b and the air pipe 17a, and the partition plate 1c is fixed to the air pipe 17a and the pressure tank body 1a. In consideration of hermeticity and strength against internal pressure, for example, each peripheral edge portion 19 is subjected to a welding process.

一方、図２（ａ）より圧力タンク上部１ｂには、液体を圧力タンク上方から液体貯留室１２へ供給できるように開閉可能な液体投入部２が設けてある。ここで液体投入部２は、液体投入管２ｂを固定しかつ液体投入口蓋２ａを取り付ける取付金具２ｄ、コックハンドル２ｃ、パッキン２ｅ及びＯリング２ｆにより構成される。ここで、取付金具２ｄは圧力タンク上面１ｂに溶接又は蝋付等により固定され、取付金具２ｄと液体投入管２ｂはＯリング２ｆによってシールされ、かつ液体投入口蓋２ａを取付金具２ｄへ取り付けた場合には、パッキン２ｅによってシールされる。従って、圧力タンク１の内部は外気から密閉され、噴霧する液体の上部に第２の気体蓄圧室１３ｂが形成される。尚、液体投入口蓋２ａを開けて噴霧する液体Ｒを注入すると液面は上昇するが、取付金具２ｄと圧力タンク上面１ｂとの溶接等及びＯリング２ｆによる密閉効果によって、前記液面の上昇は、液体投入管２ｂの下端部（図２（ａ）符号２１を参照）と接するところで止まり、入れ過ぎた液体Ｒは液体通路管２ｂを上昇し、開口した液体投入口２から噴出する。このため、第２の気体蓄圧室１３ｂは、液体投入口２ｂの長さに応じて水没することなく常に形成される。   On the other hand, as shown in FIG. 2A, the pressure tank upper part 1b is provided with a liquid input part 2 that can be opened and closed so that liquid can be supplied to the liquid storage chamber 12 from above the pressure tank. Here, the liquid charging unit 2 includes a mounting bracket 2d for fixing the liquid charging pipe 2b and attaching the liquid charging port lid 2a, a cock handle 2c, a packing 2e, and an O-ring 2f. Here, the mounting bracket 2d is fixed to the upper surface 1b of the pressure tank by welding or brazing, the mounting bracket 2d and the liquid inlet pipe 2b are sealed by the O-ring 2f, and the liquid inlet lid 2a is attached to the mounting bracket 2d. Is sealed by packing 2e. Therefore, the inside of the pressure tank 1 is sealed from the outside air, and the second gas accumulating chamber 13b is formed above the liquid to be sprayed. When the liquid R to be sprayed is injected by opening the liquid inlet lid 2a, the liquid level rises. However, the rise of the liquid level is caused by welding between the mounting bracket 2d and the pressure tank upper surface 1b and the sealing effect by the O-ring 2f. The liquid R stops when it comes into contact with the lower end of the liquid input pipe 2b (see reference numeral 21 in FIG. 2A), and the excessively filled liquid R rises in the liquid passage pipe 2b and is ejected from the opened liquid input port 2. For this reason, the second gas pressure accumulation chamber 13b is always formed without being submerged in accordance with the length of the liquid inlet 2b.

尚、空気孔１７ｂの下方近傍には、逆止バルブ１７ｄを設ける。具体的には図２（ａ）のようにエアーパイプ１７ａの上端部の内側であって、空気孔１７ｂのやや下方に、下端部の内径よりやや大きな内径部分を形成することで段差部１７ｅを設け、該段差部上に下端部の内径より大きく、上端部の内径より小さな直径を有する球体を配置することで逆止バルブ１７ｄとする。尚、該逆止バルブ１７ｄは、第１の気体蓄圧室１３ａが外部から加圧されると前記球体が浮き上がり、圧力タンク下方から上方へと気体を通過させる。一方で圧力タンクが傾き、噴霧する液体が液体貯留室１２から空気孔１７ｂを介して第１の気体蓄圧室１３ａへと侵入しようとすると、前記球体が段差部１７ｅに当接してエアーパイプ１７ａを閉鎖することで、第１の気体蓄圧室１３ａへの液体の侵入を妨げる働きをするとともに、第２の気体蓄圧室の内圧が、噴霧作業中の振動により乱れることを防止する一定の効果を発揮する。   A check valve 17d is provided near the lower portion of the air hole 17b. Specifically, as shown in FIG. 2 (a), the stepped portion 17e is formed by forming an inner diameter portion slightly inside the upper end portion of the air pipe 17a and slightly below the air hole 17b than the inner diameter of the lower end portion. The check valve 17d is formed by disposing a spherical body having a diameter larger than the inner diameter of the lower end and smaller than the inner diameter of the upper end on the stepped portion. The check valve 17d lifts the sphere when the first gas pressure accumulation chamber 13a is pressurized from the outside, and allows gas to pass from the lower side to the upper side of the pressure tank. On the other hand, when the pressure tank is tilted and the liquid to be sprayed tries to enter the first gas pressure accumulation chamber 13a from the liquid storage chamber 12 through the air hole 17b, the sphere comes into contact with the stepped portion 17e and causes the air pipe 17a to enter. By closing, it works to prevent the liquid from entering the first gas pressure accumulating chamber 13a, and at the same time exhibits a certain effect of preventing the internal pressure of the second gas pressure accumulating chamber from being disturbed by vibration during the spraying operation. To do.

You can select and use the right material. Moreover, although the sphere shown in FIG. 2A is solid, a hollow sphere can be used if it has the required strength.

また、図１に示すように、第１の気体蓄圧室１３ａの外周壁には、外部から気体を導入するための手動式のエアーポンプ２０やエアーコンプレッサー４等の汎用ポンプ（人力又は自動式のポンプを含む）を該ポンプから伸張したエアーホースを介して着脱自在に取り付けられるよう、対応した取付金具３（気体導入口）を設け、更に、第１の気体蓄圧室１３ａを加圧し過ぎる危険性を防止し、かつ内圧調整を可能とすべくリリーフバルブ５を設けた。また液体貯留室１２の外周壁には噴霧する液体を外部に噴出する液体コック７を設け、該コック７の先端部にはエアーホースを介してノズル８を取り付けることにより、該コック７の開閉調整による噴霧が可能となる。尚、該コック７の配置については、噴霧する液体を余さず吸い上げるため、例えば、図１のように該コック７の基端部から液体貯留室１２の底部（仕切板１ｃの上面）にかけて、中空状のパイプ１１を、該パイプ１１の先端が底部に近接するように伸張し、又は前記液体コック７自身を、液体貯留室１２の底部近傍に設置することが望ましい。また、圧力タンク１外周面には肩や背中の負担軽減のため弾性のある肩当てクッション９を設けることが望ましい。   As shown in FIG. 1, a general-purpose pump (manual or automatic type) such as a manual air pump 20 or an air compressor 4 for introducing gas from the outside is provided on the outer peripheral wall of the first gas pressure accumulating chamber 13a. Corresponding mounting bracket 3 (gas inlet) is provided so that the pump can be removably mounted via an air hose extended from the pump, and there is a risk that the first gas pressure accumulating chamber 13a is excessively pressurized. The relief valve 5 is provided in order to prevent the occurrence of the pressure and adjust the internal pressure. In addition, a liquid cock 7 for ejecting liquid to be sprayed to the outside is provided on the outer peripheral wall of the liquid storage chamber 12, and a nozzle 8 is attached to the tip of the cock 7 via an air hose, thereby adjusting the opening and closing of the cock 7. It becomes possible to spray by. As for the arrangement of the cock 7, in order to suck up all the liquid to be sprayed, for example, from the base end of the cock 7 to the bottom of the liquid storage chamber 12 (upper surface of the partition plate 1c) as shown in FIG. It is desirable to extend the hollow pipe 11 so that the tip of the pipe 11 is close to the bottom, or to install the liquid cock 7 itself in the vicinity of the bottom of the liquid storage chamber 12. Further, it is desirable to provide an elastic shoulder pad cushion 9 on the outer peripheral surface of the pressure tank 1 in order to reduce the burden on the shoulder and back.

尚、第１の気体蓄圧室１３ａへ誤って侵入した液体を外部に排出することを考慮して、タンク底板１ｄは、例えば底板１ｄの中央に向かって下り傾斜を有する構造とし、中央に液体排出用のドレン１８を設けることが望ましい。また、取付金具１７ｃは上部へ向かって開口させ、開口部にはネジ構造等により着脱可能とした気体圧力計６等を設けることが望ましい。   In consideration of discharging the liquid accidentally entering the first gas pressure accumulating chamber 13a to the outside, the tank bottom plate 1d has, for example, a structure having a downward slope toward the center of the bottom plate 1d, and the liquid discharge at the center. It is desirable to provide a drain 18 for use. Further, it is desirable that the mounting bracket 17c is opened upward, and the opening is provided with a gas pressure gauge 6 etc. that can be attached and detached by a screw structure or the like.

以上の構成による実施形態１の噴霧器を使用すると、図３に示す通り、使用時に圧力タンク１を若干前傾させると、圧力タンク１を背負う者は、接触する該タンク胴部１ａの外周面からその背中に対し、圧力タンク１に対し下向きにかかる力ｇのうち、背中方向に及ぼす力ｇｗを受けることとなる。しかし力ｇｗは腰位置Ｗの位置と略同じ高さ以上の位置において作用するため、腰への負荷と両肩が後方へ引っ張られる力が軽減される。 When the sprayer of Embodiment 1 having the above configuration is used, as shown in FIG. 3, when the pressure tank 1 is tilted slightly forward during use, a person who carries the pressure tank 1 from the outer peripheral surface of the tank body 1a that comes into contact with The force gw exerted in the back direction among the force g applied downward to the pressure tank 1 is received against the back. However, since the force gw acts at a position that is substantially equal to or higher than the position of the waist position W, the load on the waist and the force with which both shoulders are pulled backward are reduced.

次に、実施形態２に係る噴霧器を図４に基づいて説明する。実施形態１におけるノズル８を装着した圧力タンク１及び着脱可能なエアーコンプレッサー４をコンプレッサーキャリヤー１６を介してキャリヤー１４に搭載し、前記圧力タンク１はタンク取り付けバンド１５等によりキャリヤー１４に固定する。そして、圧力タンク１の取付金具３にはエアーコンプレッサー１４の気体排出口から伸張したエアーホース（図示せず）を取り付ける。以上の構成により実施形態２の噴霧器を使用すると、移動しながらの噴霧作業において、作業者が圧力タンク１を背負う負担から開放される。   Next, a sprayer according to Embodiment 2 will be described with reference to FIG. The pressure tank 1 equipped with the nozzle 8 and the detachable air compressor 4 in the first embodiment are mounted on the carrier 14 through the compressor carrier 16, and the pressure tank 1 is fixed to the carrier 14 by a tank mounting band 15 or the like.
