【発明の属する技術分野】
本発明は粒剤散布噴頭に係わり、特に粒剤の均等散布重点作業と到達重点作業がひとつの噴頭で出来、作業範囲が広く、散布精度の高い作業が実現出来る粒剤散布噴頭に関する。
【0002】
【従来の技術】
図4に従来の薬剤散布装置の構成を示す。図4において、薬剤散布装置10は、背負式である。薬剤タンク1には、農薬や肥料等の粒剤が入れられている。エンジン3により送風機5が駆動され、この送風機5から送られる風により粒剤が搬送される。
【0003】
そして、この粒剤は、筒状の噴頭7の下部に配設された吐出口9及び噴頭7の先端に配設された先端開口11から吐出される。吐出口9は、噴頭7に下方に向かい複数個設けられている。吐出口9には、図示しない風案内部材が噴頭7内部に向けて突設されている。風案内部材の風上側には風入力口が配設され、風に搬送された粒剤は、この風入力口に導かれて吐出口9より外部に出される。
【0004】
ここに、先端開口11は、出来るだけ粒剤を遠くへ飛ばすべく主に到達性を担って設けられている。一方、吐出口9は、作業者から先端開口11による到達点迄の間の散布を出来るだけ均等に行うべく均等性を担って設けられている。
【0005】
【発明が解決しようとする課題】
しかしながら、従来の薬剤散布装置10では、風案内部材の空気抵抗により噴頭7の先端に流れる風の量は減り、かつこの風案内部材の突設の影響で、乱流が発生し、粒剤の到達距離を延ばせなかった。
【0006】
このため、圃場が広い場合には、粒剤の届かない部分を多く生じていた。また、粒剤の到達距離を延ばそうと噴頭7の先端を高く傾斜させると、散布されない場所が多く生じてしまう。
【0007】
本発明はこのような従来の課題に鑑みてなされたもので、粒剤の均等散布重点作業と到達重点作業がひとつの噴頭で出来、作業範囲が広く、散布精度の高い作業が実現出来る粒剤散布噴頭を提供することを目的とする。
【0008】
【課題を解決するための手段】
このため本発明(請求項1)は、内部の通路において送風により粒剤が搬送される筒状体(35)と、該筒状体(35)の所定箇所に設けられ、前記風に搬送された前記粒剤が吐出される少なくとも一つ以上の吐出口(9)と、該吐出口(9)の縁部内側より前記筒状体(35)の内部に向けて該吐出口(9)の風下側より風上側に傾斜突設させ、風上側に風入力口(27)が配設され、風下側が閉鎖された風案内手段(20)と、該風案内手段(20)の前記風入力口(27)の開閉調節及び該風案内手段(20)の前記風に対する空気抵抗が調節自在である開閉調節手段(29、31、33)とを備えた粒剤散布噴頭であって、前記風案内手段(20)は、前記吐出口(9)の風下側縁部及び/又は前記筒状体(35)の軸方向左右の左右側縁部の内側となるように風上側に向けて開かれた三角形状縁部(23)が形成され、前記筒状体(35)の外壁に沿って配設された底面(21)と、該底面(21)の三角形状縁部(23)より風下側から風上側に向けて左右対称な少なくとも2枚の平面(25a、25b)により山形に傾斜突設された突設部(25)と、該突設部(25)の風上側に前記平面(25a、25b)及び前記筒状体(35)により形成された風入力口(27)とを有し、前記開閉調節手段(29、31、33)は、前記風入力口(27)及び前記底面(21)の三角形状縁部(23)の開口面積を前記筒状体(35)の軸方向の左及び/又は右から開閉調節可能な操作部(33)と、該操作部(33)による操作により前記筒状体(35)の外壁に沿って前記底面(21)が軸方向左及び/又は右に摺動自在の摺動部(29、31)とを有することを特徴とする。
【0009】
筒状体(35)の内部では、送風により粒剤が搬送される。そして、筒状体
(35)の所定箇所には吐出口(9)が少なくとも一つ以上設けられ、風に搬送された粒剤がこの吐出口(9)から吐出される。風案内手段(20)は、吐出口(9)の縁部内側より筒状体(35)の内部に向けて、吐出口(9)の風下側より風上側に傾斜突設されている。
【0010】
この傾斜突設の傾斜は、流線型や直線状が望ましいが、風向が屈曲可能であれば形状は問わない。そして、この風案内手段(20)の風上側には風入力口(27)が配設され、風下側は閉鎖されている。従って、筒状体(35)内で風により搬送された粒剤は、風案内手段(20)の風入力口(27)より入る。そして、傾斜突設の傾斜によって導かれて吐出口(9)から吐出される。
【0011】
開閉調節手段(29、31、33)では、風案内手段(20)の風入力口(27)の開閉調節及び風案内手段(20)の風に対する空気抵抗が調節自在である。風案内手段(20)は、筒状体(35)の内部に向けて突設されているため、風の抵抗となっている。
【0012】
この抵抗を小さく抑えられれば、風案内手段(20)の先端まで風力が衰えずに送風される。従って、この空気抵抗を適度に調節することにより、粒剤を吐出口(9)より均等に散布可能である。風入力口(27)の開閉調節と空気抵抗の調節は同時に出来るのが操作上望ましい。構造的にも簡単である。
【0013】
以上により、粒剤の散布バランスが簡単に調節出来、散布精度の高い作業が実現出来る。
【0014】
さらに、風案内手段(20)は、筒状体(35)の外壁に沿って配設された底面(21)を有している。この底面(21)には、三角形状縁部(23)が形成されている。三角形状縁部(23)は、吐出口(9)の風下側縁部及び/又は噴頭の軸方向左右の左右側縁部の内側となるように配設される。三角形状は、風上側に向けて開かれている。そして、この底面(21)の三角形状縁部(23)より突設部(25)が隆起形成されている。突設部(25)は、風下側から風上側に向けて、左右対称な少なくとも2枚の平面(25a、25b)により山形に傾斜突設されている。突設部(25)の風上側には、これらの平面(25a、25b)及び筒状体(35)により風入力口(27)が形成されている。
【0015】
また、開閉調節手段(29、31、33)は、風入力口(27)及び底面(21)の三角形状縁部(23)の開口面積を、筒状体(35)の軸方向の左及び/又は右から開閉調節可能な操作部(33)を有している。そして、この操作部
(33)による操作により、筒状体(35)の外壁に沿って底面(21)が軸方向左及び/又は右に摺動自在の摺動部(29、31)が配設されている。
【0016】
突設部(25)の平面(25a、25b)を左右対称としたことにより、平面同士が操作部(33)による操作により、合わせやすい。また、三角形状縁部
(23)の左右も一致させやすい。このため、合わせたときの風の空気抵抗も小さく出来る。
【0017】
更に、本発明(請求項)は、前記操作部(33)は、前記底面(21)の軸方向の左及び/又は右に配設されたツマミ(33)であり、前記摺動部(29、31)は、前記底面(21)の三角形状縁部(23)の三角形状の頂部を中心として、三角形状の底部が軸方向の左及び/又は右に開閉可能なように前記底面
(21)の左及び/又は右に配設されたスライド穴(29)と、該スライド穴
(29)と前記筒状体(35)を貫通するネジ(31)を備えて構成した。
【0018】
ツマミ(33)、スライド穴(29)及びネジ(31)は底面(21)の左右に配設してもよいし、左右のいずれか一方のみに配設してもよい。一方のみに配設した場合には、他方の底面(21)は筒状体(35)の外壁に固着等する。そして、この他方の底面(21)には、ツマミ(33)、スライド穴(29)は設けない。
【0019】
以上により、簡単な構成で、風入力口(27)の開閉調節と空気抵抗の調節が同時に行える。また、操作も簡単である。
【0020】
更に、本発明(請求項)は、前記筒状体(35)の先端には、前記風に搬送された前記粒剤が吐出される先端開口(11)が配設されたことを特徴とする。
【0021】
先端開口(11)からも風に搬送された粒剤を吐出させる。各吐出口(9)の操作部(33)は独自に操作可能である。従って、個々の吐出口(9)からの粒剤の吐出量は連続的に調節可能である。すべての吐出口(9)からの粒剤の吐出量をゼロにした場合には、先端開口(11)からの風は最も風力が強くなる。
【0022】
従って、粒剤の到達点も最長になり、作業範囲を広く取れる。また、余り到達点を遠く必要としない場合には、各吐出口(9)の操作部(33)を適度に調節することにより、粒剤の均等散布が可能である。
【0023】
このように、粒剤の均等散布重点作業と到達重点作業がひとつの筒状体(35)で出来、作業範囲が広く、散布精度の高い作業が可能である。また、ひとつの筒状体(35)での作業範囲が広いことから経済的である。
【0024】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づいて説明する。本発明の実施形態の斜視構成図を図1に示す。薬剤散布装置10は従来と同じものを用いている。図1において、筒状体35の下部には、吐出口9が配設されている。吐出口9は三角形状であり、風の下流側に頂部9aが、また上流に向かってこの頂部9aから開くように左右対称に開けられている。そして、吐出口9の三角形状の底部9bは、筒状体35の軸方向と直角に位置している。
【0025】
風案内部材20はほぼ三角形状の底面21を有している。そして、この底面21は、筒状体35の外壁に沿って配設するため、筒状体35の外壁と曲線形状が合うように曲げ加工が施されている。この底面21には、左右対称の三角形状縁部23が形成されている。そして、この三角形状縁部23より隆起するように突設部25が形成されている。
【0026】
突設部25は、風下側から風上側に向けて傾斜突設するように、左右対称な2枚の平面25a、25bにより山形に傾斜突設されている。2つの平面25a、25bにより山形の稜線25cが形成されている。また、底面21の風上側には、突設部25を挟んで対称にスライド穴29a、29bが配設されている。
底面21の左右の風上側の端部は折曲されて、ツマミ33a、33bが形成されている。
【0027】
突設部25は、吐出口9より筒状体35の内部に入れられるようになっている。そして、スライド穴29a、29bを貫通してネジ31a、31bが通され、ネジ31a、31bの先端は、筒状体35に螺着されている。
【0028】
また、底面21の風下側はネジ31cにより、筒状体35に螺着されている。スライド穴29a、29bは、ネジ31a、31bに案内されて左右に摺動可能なようになっている。突設部25の風上側には、これらの平面25a、25b及び筒状体35により風入力口27が形成されている。
【0029】
次に、本発明の実施形態の動作を説明する。
粒剤を均等散布する場合には、図2に示すように、ツマミ33a、33bを左右に開いて風入力口27を広く開放する。風に搬送された粒剤は、突設部25により吐出口9に案内されて外部に放出される。
【0030】
一方、粒剤の到達距離を延ばしたい場合には、図3に示すように、各吐出口9に対応するすべてのツマミ33a、33bを閉じる。このとき、風入力口27は閉じられ、空気抵抗は最も小さくなる。従って、粒剤は先端開口11に集中され最も遠くに飛ばされる。
【0031】
このため、例えば到達距離が要求される圃場において、標準の散布後、到達距離をのばした散布に切り替える等の作業が簡単に行える。また、これらの吐出口9のツマミ33a、33bを個別に調節すれば、一層きめの細かい散布需要に対応させることが可能である。
【0032】
なお、底面21の左右の一方を筒状体35に固着させ、ツマミ33とスライド穴29は他方のみに配設するようにしてもよい。
【0033】
以上により、粒剤の均等散布重点作業と到達重点作業がひとつの噴頭7で出来、作業範囲が広く、散布精度の高い作業が可能である。構造は簡素で部材も少なく、操作も簡単である。
【0034】
【発明の効果】
以上説明したように本発明によれば、筒状体(35)に配設された吐出口(9)には風案内手段(20)と開閉調節手段(29、31、33)を備えて構成したので、粒剤の均等散布重点作業と到達重点作業がひとつの噴頭(7)で出来、作業範囲が広く、散布精度の高い作業が実現出来る。
また、この風案内手段(20)は突設部(25)を備え、この突設部(25)の平面(25a、25b)を左右対称にしたので、平面同士が操作部(33)による操作により、合わせやすい。また、三角形状縁部(23)の左右も一致させやすい。このため、合わせたときの風の空気抵抗も小さく出来る。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a granule spraying jet, and more particularly to a granule spraying jet capable of performing a work for emphasizing even distribution of granules and a work for achieving a priority of granulation with one jet, and having a wide working range and a work with high spraying accuracy.
[0002]
[Prior art]
FIG. 4 shows a configuration of a conventional medicine spraying device. In FIG. 4, the medicine spraying device 10 is a backpack type. The medicine tank 1 contains granules such as pesticides and fertilizers. The blower 5 is driven by the engine 3, and the granules are conveyed by the wind sent from the blower 5.
[0003]
Then, the granules are discharged from a discharge port 9 provided below the cylindrical jet head 7 and a tip opening 11 provided at the tip of the jet head 7. A plurality of discharge ports 9 are provided at the jet head 7 downward. At the discharge port 9, a wind guide member (not shown) is provided so as to project toward the inside of the jet head 7. A wind input port is provided on the windward side of the wind guide member, and the granules conveyed by the wind are guided to the wind input port and discharged from the discharge port 9 to the outside.
[0004]
Here, the front end opening 11 is provided mainly for attaining reach so as to fly the granules as far as possible. On the other hand, the discharge port 9 is provided with uniformity so that the spraying from the worker to the point reached by the tip opening 11 is performed as evenly as possible.
[0005]
[Problems to be solved by the invention]
However, in the conventional medicine spraying device 10, the amount of wind flowing at the tip of the jet head 7 is reduced due to the air resistance of the wind guide member, and turbulence is generated due to the effect of the projecting of the wind guide member, so that the granules are dispersed. I couldn't extend the reach.
[0006]
For this reason, when the field is wide, many portions where the granule cannot reach are generated. In addition, if the tip of the jet head 7 is inclined at a high angle in order to extend the reach of the granules, many places where the spray is not sprayed occur.
[0007]
The present invention has been made in view of such a conventional problem, and a granule capable of realizing a work with a wide working range and a high spraying precision can be performed with a single spray head, with the work of emphasizing the uniform spraying and the work of reaching the arrival of the granule being performed by one jetting head. It is intended to provide a scatter jet.
[0008]
[Means for Solving the Problems]
Therefore, the present invention (Claim 1) provides a tubular body (35) in which granules are transported by blowing air in an internal passage, and is provided at a predetermined position of the tubular body (35) and transported by the wind. And at least one discharge port (9) through which the granules are discharged, and the discharge port (9) is directed from the inside of the edge of the discharge port (9) toward the inside of the tubular body (35). A wind guide means (20) having a wind input port (27) arranged on the windward side and projecting upward from the leeward side, and a leeward side closed, and the wind input port of the wind guide means (20) (27) a granule spraying噴頭 the air resistance and a closing control means (29, 31, 33) is adjustable with respect to the wind-off regulation and該風guide means (20) of said wind guide The means (20) is provided on the leeward side of the discharge port (9) and / or on the left and right of the cylindrical body (35) in the axial direction.

[0011]
The opening / closing adjusting means (29, 31, 33) is capable of adjusting the opening / closing of the wind input port (27) of the wind guiding means (20) and the air resistance of the wind guiding means (20) against the wind. Since the wind guide means (20) is protruded toward the inside of the tubular body (35), it acts as a wind resistance.
[0012]
If this resistance can be kept small, the wind will be blown to the tip of the wind guide means (20) without attenuating. Therefore, by appropriately adjusting the air resistance, the granules can be evenly sprayed from the discharge port (9). It is operationally desirable that the opening and closing adjustment of the wind input port (27) and the adjustment of the air resistance can be performed simultaneously. It is simple in structure.

Furthermore, the wind guide means (20) has a bottom surface (21) arranged along the outer wall of the tubular body (35). The bottom surface (21) has a triangular edge (23). The triangular edge (23) is disposed inside the leeward edge of the discharge port (9) and / or the left and right lateral edges in the axial direction of the jet head. The triangular shape is open to the windward side. A protruding portion (25) is formed so as to protrude from the triangular edge (23) of the bottom surface (21). The protruding portion (25) is inclined and protruded from the leeward side to the leeward side in a mountain shape by at least two symmetrical planes (25a, 25b). On the windward side of the protruding portion (25), a wind input port (27) is formed by these planes (25a, 25b) and the tubular body (35).
[0015]
The opening / closing adjusting means (29, 31, 33) adjusts the opening area of the wind input port (27) and the triangular edge (23) of the bottom surface (21) to the left and the right in the axial direction of the cylindrical body (35). And / or an operation unit (33) that can be opened and closed from the right.

Is established.
[0016]
Since the planes (25a, 25b) of the protruding portion (25) are left-right symmetric, the planes can be easily aligned by the operation of the operation section (33). Further, the right and left sides of the triangular edge (23) can be easily matched. For this reason, the air resistance of the wind when combined can be reduced.
[0017]
Further, according to the present invention (claim 2 ), the operating portion (33) is a knob (33) disposed on the left and / or right in the axial direction of the bottom surface (21), and the sliding portion (33) is provided. The bottom surface (29, 31) is arranged such that the triangular bottom portion can be opened and closed left and / or right in the axial direction with the triangular edge portion (23) of the bottom surface (21) as a center. 21) A slide hole (29) disposed on the left and / or right side of (21), and a screw (31) penetrating the slide hole (29) and the cylindrical body (35).

Further, the present invention (claim 3 ) is characterized in that a distal end opening (11) from which the granular material conveyed by the wind is discharged is disposed at a distal end of the cylindrical body (35). I do.
[0021]
The granules conveyed by the wind are also discharged from the tip opening (11). The operation section (33) of each discharge port (9) can be operated independently. Therefore, the discharge amount of the granules from the individual discharge ports (9) can be continuously adjusted. When the discharge amount of the granules from all the discharge ports (9) is set to zero, the wind from the tip opening (11) has the strongest wind force.
[0022]
Therefore, the arrival point of the granule becomes the longest, and the working range can be widened. In addition, when it is not necessary to reach a far reaching point, by appropriately adjusting the operation unit (33) of each discharge port (9), it is possible to evenly distribute the granules.
[0023]
In this manner, the work of emphasizing the uniform dispersion of granules and the work of achieving the arrival of the granules can be performed by one cylindrical body (35), and the work can be performed with a wide working range and high spraying accuracy. In addition, it is economical because the working range of one cylindrical body (35) is wide.

Left and right windward ends of the bottom surface 21 are bent to form knobs 33a and 33b.
[0027]
The protruding portion 25 is configured to be inserted into the inside of the cylindrical body 35 through the discharge port 9. The screws 31a and 31b pass through the slide holes 29a and 29b, and the tips of the screws 31a and 31b are screwed to the tubular body 35.
[0028]
Further, the leeward side of the bottom surface 21 is screwed to the tubular body 35 by a screw 31c. The slide holes 29a, 29b are guided by the screws 31a, 31b so that they can slide left and right. On the windward side of the projecting portion 25, a wind input port 27 is formed by the flat surfaces 25a and 25b and the cylindrical body 35.
[0029]
Next, the operation of the embodiment of the present invention will be described.
When spraying the granules evenly, the knobs 33a and 33b are opened to the left and right to widely open the wind input port 27, as shown in FIG. The granule conveyed by the wind is guided to the discharge port 9 by the projecting portion 25 and discharged to the outside.
[0030]
On the other hand, when it is desired to extend the reach of the granules, as shown in FIG. 3, all the knobs 33a and 33b corresponding to each discharge port 9 are closed. At this time, the wind input port 27 is closed, and the air resistance is minimized. Therefore, the granules are concentrated on the front end opening 11 and blown farthest.
[0031]
For this reason, for example, in a field where a reach distance is required, operations such as switching to spreading with a longer reach after standard spraying can be easily performed. Further, if the knobs 33a and 33b of the discharge ports 9 are individually adjusted, it is possible to cope with a demand for finer spraying.
[0032]
Note that one of the left and right sides of the bottom surface 21 may be fixed to the cylindrical body 35, and the knob 33 and the slide hole 29 may be provided only on the other.
[0033]
As described above, the uniform spray emphasis work and the arrival emphasis work of the granule can be performed by one jetting head 7, so that the work range is wide and the work with high spraying accuracy is possible. The structure is simple, the number of members is small, and the operation is simple.
[0034]
【The invention's effect】
As described above, according to the present invention, the discharge port (9) provided in the tubular body (35) is provided with the wind guide means (20) and the opening / closing adjusting means (29, 31, 33). As a result, the work of emphasizing the uniform spraying of granules and the work of reaching the arrival of the granules can be performed by a single jet head (7), and a work with a wide working range and high spraying accuracy can be realized.
The wind guide means (20) has a projecting portion (25), and the planes (25a, 25b) of the projecting portion (25) are symmetrical, so that the planes can be operated by the operation unit (33). Easy to match Further, the right and left sides of the triangular edge (23) can be easily matched. For this reason, the air resistance of the wind when combined can be reduced.
