Description
本発明は、ホッパに充填される散布対象物がホースで誘導され、ホースの下端を保持するホース保持部に取り付けて散布対象物を土壌表面に落下させる散布用ノズルに関する。 The present invention relates to a spray nozzle in which the material to be sprayed is loaded into a hopper and guided by a hose, and is attached to a hose holder that holds the lower end of the hose, causing the material to be sprayed to fall onto the soil surface.
生産者の高齢化、大規模化にともない、水稲の省力・低コスト生産技術である湛水直播への関心が高まっている。湛水直播栽培の一層の省力化、低コスト化を進めるために、本発明者らは、幅２．０～２．６ｍのハローに取り付けて使用する代かき同時浅層土中播種ノズルを開発した。このような播種機では条播時に播種ノズルを利用して播種する。
特許文献１から特許文献４には施肥ノズルが開示されている。これらの施肥ノズルにおいてもノズルの肥料排出口に土が詰まらないような構成が採用されている。
また、特許文献１から特許文献４に開示されているような施肥ノズルは、土壌表面から所定深さの位置に施肥を行う必要があるため、施肥ノズルの少なくとも一部を土壌中に埋没させて用いる。
As farmers age and farms become larger, interest in flooded direct seeding, a labor-saving, low-cost rice production technique, is growing. In order to further reduce labor and costs in flooded direct seeding, the inventors have developed a shallow soil seeding nozzle that can be attached to a 2.0-2.6m wide harrow for simultaneous puddling and shallow soil seeding. With this type of seeding machine, the seeding nozzle is used for row sowing.
Fertilization nozzles are disclosed in Patent Documents 1 to 4. These fertilization nozzles also employ a configuration that prevents soil from clogging the fertilizer outlet of the nozzle.
In addition, since the fertilization nozzles disclosed in Patent Documents 1 to 4 need to apply fertilization at a predetermined depth from the soil surface, the fertilization nozzle is used with at least a portion of it buried in the soil.
このような少なくとも一部を土壌中に埋没させて用いる施肥ノズルに対して、土壌表面に、種子、肥料、又は農薬などの散布対象物を落下させる散布用ノズルは、地表面より高い位置で用いられる。従って、散布対象物の散布時には、散布用ノズルに土が詰まることはない。
しかし、誤って畦に散布用ノズルを刺してしまうと土が詰まり散布ができなくなってしまうことがある。
施肥ノズルに有する作溝部材は、作溝のための部材であることから、土壌中に挿入しやすい部材であり、このような作溝部材を散布用ノズルに適用しても、開口部に土が詰まることを十分に阻止することはできない。
In contrast to such a fertilizer nozzle that is used by being at least partially buried in the soil, a spray nozzle that drops the target material, such as seeds, fertilizer, or pesticide, onto the soil surface is used at a position higher than the ground surface, so that the spray nozzle does not become clogged with soil when the target material is sprayed.
However, if the spray nozzle is accidentally inserted into the ridge, the soil may become clogged and spraying may become impossible.
The furrow making member on a fertilizer nozzle is a member for making furrows, and is therefore a member that is easy to insert into the soil. Even if such a furrow making member is applied to a spraying nozzle, it is not possible to sufficiently prevent soil from clogging the opening.
本発明は、誤って畦に散布用ノズルを刺してしまった場合に、開口部に土が詰まることを阻止することができる散布用ノズルを提供することを目的とする。 The present invention aims to provide a spray nozzle that can prevent soil from clogging the opening if the nozzle is accidentally inserted into a ridge.

A spray nozzle according to an embodiment of the present invention will be described below using a seeding nozzle.
FIG. 1 is a photograph showing a seed planter using a spray nozzle according to the present invention.
In the spraying nozzle 1 according to this embodiment, seeds filled in a hopper 2 are guided by a hose 3, and the lower end of the hose 3 is attached to a hose holding part 4, causing the seeds to fall onto the soil surface. Note that, although this embodiment will be described as being about seeds as the object to be sprayed, other than seeds, fertilizers, pesticides, etc. may also be sprayed.
図２は本発明の第１実施例による散布用ノズルを示す構成図であり、図２（ａ）は土壌表面に接触しない状態での散布用ノズルの正面図、図２（ｂ）は図２（ａ）の右側面図、図２（c）は土壌表面に押圧された状態での散布用ノズルの正面図、図２（d）は図２（c）の右側面図である。
第１実施例による散布用ノズル１は、種子を落下させる空洞１０を形成するノズル本体１１と、種子を土壌表面Ｘに落下させる開口部２０と、開口部２０より下方に位置する阻止部材３０とを備えている。開口部２０はノズル本体１１の下端、すなわち空洞１０の下端に形成されている。
阻止部材３０の下端３１が土壌表面Ｘに押圧された場合には、図２（c）及び図２（d）に示すように、阻止部材３０が屈曲して、阻止部材３０が開口部２０と土壌表面Ｘとの間に位置することで、阻止部材３０によって開口部２０に土が詰まることを阻止する。
このように、第１実施例による散布用ノズル１は、阻止部材３０の下端３１が土壌表面Ｘに押圧されると阻止部材３０が屈曲し、阻止部材３０が屈曲することで、阻止部材３０が開口部２０と土壌表面Ｘとの間に位置するため、開口部２０に土が詰まることがない。
本実施例による阻止部材３０は平板材で構成し、阻止部材３０の下端３１が、空洞１０の仮想軸線Ｙに近接するように、阻止部材３０を傾斜させている。
このように、阻止部材３０を平板材とし、阻止部材３０を傾斜させることで、阻止部材３０を確実に開口部２０側に屈曲させることができ、阻止部材３０を開口部２０と土壌表面Ｘとの間に位置させることができる。なお、阻止部材３０は、蝶番や関節のような機構的な構造による屈曲よりも、樹脂等の可撓性部材で形成することで屈曲することが好ましい。また、阻止部材３０だけでなく、散布用ノズル１全体を樹脂等の可撓性部材で形成することが好ましい。可撓性部材による屈曲では、泥や塵の付着による屈曲動作への影響が少なく、機構的な構造による屈曲よりも優れている。
Figure 2 is a schematic diagram showing a spray nozzle according to the first embodiment of the present invention, where Figure 2(a) is a front view of the spray nozzle when not in contact with the soil surface, Figure 2(b) is a right side view of Figure 2(a), Figure 2(c) is a front view of the spray nozzle pressed against the soil surface, and Figure 2(d) is a right side view of Figure 2(c).
The spraying nozzle 1 according to the first embodiment comprises a nozzle body 11 forming a cavity 10 for dropping seeds, an opening 20 for dropping seeds onto the soil surface X, and a blocking member 30 located below the opening 20. The opening 20 is formed at the lower end of the nozzle body 11, i.e., at the lower end of the cavity 10.
When the lower end 31 of the blocking member 30 is pressed against the soil surface X, as shown in Figures 2(c) and 2(d), the blocking member 30 bends and is positioned between the opening 20 and the soil surface X, thereby preventing soil from clogging the opening 20.
In this way, in the spray nozzle 1 of the first embodiment, when the lower end 31 of the blocking member 30 is pressed against the soil surface X, the blocking member 30 bends, and as a result, the blocking member 30 is positioned between the opening 20 and the soil surface X, so that soil does not become clogged in the opening 20.
The blocking member 30 in this embodiment is made of a flat plate material, and is inclined so that the lower end 31 of the blocking member 30 is close to the imaginary axis Y of the cavity 10.
In this way, by making the blocking member 30 a flat plate material and inclining the blocking member 30, the blocking member 30 can be reliably bent toward the opening 20 side, and the blocking member 30 can be positioned between the opening 20 and the soil surface X. It is preferable that the blocking member 30 be bent by forming it from a flexible material such as resin rather than bending it by a mechanical structure such as a hinge or joint. It is also preferable that not only the blocking member 30 but also the entire spray nozzle 1 be formed from a flexible material such as resin. Bending by a flexible material has less effect on the bending operation due to the adhesion of mud and dust, and is superior to bending by a mechanical structure.
図３は本発明の第１実施例による散布用ノズルの実証試験を示す写真である。
図３（ａ）は本実施例による散布用ノズルを図２（c）及び図２（d）のように土壌表面に押圧した状態、図３（ｂ）は図３（ａ）の状態の後に土壌表面から引き上げた状態、図３（c）は比較例による散布用ノズルを図２（c）及び図２（d）のように土壌表面に押圧した状態、図３（d）は図３（c）の状態の後に土壌表面から引き上げた状態を示し、図３（e）は比較例による散布用ノズルを示している。
図３（e）に示すように、比較例による散布用ノズルは、開口部２０より下方に一対の延出部を形成しているが、押圧によって屈曲する阻止部材３０を備えていない。
図３（d）に示すように、比較例による散布用ノズルでは土詰まりが生じたが、図３（ｂ）に示すように、本実施例による散布用ノズル１では、土詰まりを生じることがなかった。
FIG. 3 is a photograph showing a demonstration test of the spray nozzle according to the first embodiment of the present invention.

As shown in FIG. 3(e), the spray nozzle according to the comparative example has a pair of extending portions formed below the opening 20, but does not have a blocking member 30 that bends when pressed.
As shown in FIG. 3(d), the spraying nozzle of the comparative example became clogged with soil, but as shown in FIG. 3(b), the spraying nozzle 1 of the present embodiment did not become clogged with soil.
図４は本発明の第２実施例による散布用ノズルを示す構成図であり、図４（ａ）は土壌表面に接触しない状態での散布用ノズルの正面図、図４（ｂ）は図４（ａ）の右側面図、図４（c）は土壌表面に押圧された状態での散布用ノズルの正面図、図４（d）は図４（c）の右側面図である。
第２実施例による散布用ノズル１は、種子を落下させる空洞１０を形成するノズル本体１１と、種子を土壌表面Ｘに落下させる開口部２０と、開口部２０より下方に位置する阻止部材３０とを備え、阻止部材３０として、第１阻止部材３０ａと第２阻止部材３０ｂとを有している。開口部２０はノズル本体１１の下端、すなわち空洞１０の下端に形成されている。
第１阻止部材３０ａと第２阻止部材３０ｂとは、対向させて配置している。
阻止部材３０の下端３１が土壌表面Ｘに押圧された場合には、図４（c）及び図４（d）に示すように、阻止部材３０が屈曲して、阻止部材３０が開口部２０と土壌表面Ｘとの間に位置することで、阻止部材３０によって開口部２０に土が詰まることを阻止する。
このように、第２実施例による散布用ノズル１は、阻止部材３０の下端３１が土壌表面Ｘに押圧されると阻止部材３０が屈曲し、阻止部材３０が屈曲することで、阻止部材３０が開口部２０と土壌表面Ｘとの間に位置するため、開口部２０に土が詰まることがない。
本実施例による阻止部材３０は平板材で構成し、阻止部材３０の下端３１が、空洞１０の仮想軸線Ｙに近接するように、阻止部材３０を傾斜させている。
このように、阻止部材３０を平板材とし、阻止部材３０を傾斜させることで、阻止部材３０を確実に開口部２０側に屈曲させることができ、阻止部材３０を開口部２０と土壌表面Ｘとの間に位置させることができる。
また、阻止部材３０として、第１阻止部材３０ａと第２阻止部材３０ｂとを有することで、少なくともいずれかの阻止部材３０を開口部２０と土壌表面Ｘとの間に位置させることができる。
Figure 4 is a schematic diagram showing a spray nozzle according to a second embodiment of the present invention, where Figure 4(a) is a front view of the spray nozzle when not in contact with the soil surface, Figure 4(b) is a right side view of Figure 4(a), Figure 4(c) is a front view of the spray nozzle pressed against the soil surface, and Figure 4(d) is a right side view of Figure 4(c).
The spraying nozzle 1 according to the second embodiment comprises a nozzle body 11 forming a cavity 10 for dropping seeds, an opening 20 for dropping seeds onto the soil surface X, and a blocking member 30 located below the opening 20. The blocking member 30 includes a first blocking member 30a and a second blocking member 30b. The opening 20 is formed at the lower end of the nozzle body 11, i.e., at the lower end of the cavity 10.
The first blocking member 30a and the second blocking member 30b are disposed opposite each other.
When the lower end 31 of the blocking member 30 is pressed against the soil surface X, as shown in Figures 4(c) and 4(d), the blocking member 30 bends and is positioned between the opening 20 and the soil surface X, thereby preventing soil from clogging the opening 20.
In this way, in the spray nozzle 1 of the second embodiment, when the lower end 31 of the blocking member 30 is pressed against the soil surface X, the blocking member 30 bends, and as a result, the blocking member 30 is positioned between the opening 20 and the soil surface X, so that soil does not become clogged in the opening 20.
The blocking member 30 in this embodiment is made of a flat plate material, and is inclined so that the lower end 31 of the blocking member 30 is close to the imaginary axis Y of the cavity 10.
In this way, by making the blocking member 30 into a flat plate material and inclining the blocking member 30, the blocking member 30 can be reliably bent toward the opening 20, and the blocking member 30 can be positioned between the opening 20 and the soil surface X.
Furthermore, by having the first blocking member 30a and the second blocking member 30b as the blocking member 30, at least one of the blocking members 30 can be positioned between the opening 20 and the soil surface X.
なお、第２実施例による散布用ノズル１についても、阻止部材３０は、蝶番や関節のような機構的な構造による屈曲よりも、樹脂等の可撓性部材で形成することで屈曲することが好ましい。また、阻止部材３０だけでなく、散布用ノズル１全体を樹脂等の可撓性部材で形成することが好ましい。可撓性部材による屈曲では、泥や塵の付着による屈曲動作への影響が少なく、機構的な構造による屈曲よりも優れている。
また、第２実施例による散布用ノズル１についても、可撓性ある阻止部材３０を、下端を斜め後方に傾けて用いることで開口部２０への土の詰まりを更に防止できる。
In the spray nozzle 1 according to the second embodiment, it is preferable that the blocking member 30 is bent by being made of a flexible material such as resin, rather than by being bent by a mechanical structure such as a hinge or joint. It is also preferable that not only the blocking member 30 but also the entire spray nozzle 1 is made of a flexible material such as resin. Bending by a flexible material has less effect on the bending operation due to the adhesion of mud or dust, and is superior to bending by a mechanical structure.
