Description

本発明は、茶園における機械化、省人化等の面から、茶刈機、防除機(陸上、空中の防除機)等の茶園管理装置が普及したことに鑑み、この茶園管理装置の使用に障害がない手動で操作できる折畳み式の首機構を備えた防霜ファン装置に関する。   The present invention has an obstacle to the use of tea garden management devices in view of the widespread use of tea garden management devices such as tea mowers and control machines (land and air control machines) from the viewpoint of mechanization and labor saving in tea gardens. The present invention relates to an anti-frost fan device having a folding neck mechanism that can be operated manually without any folds.

周知の如く、茶園の機械化、省人化等の面から、茶園管理装置が採用されるようになった。これに伴って、現在の建柱・架線を利用した防霜ファン装置の弊害が指摘されている。即ち、茶園、又は茶樹等の圃場に建柱が立設され、この建柱に向かって張装された架線等が、茶園管理装置の移動、作業の際に邪魔となり、摘採、摘枝、防除等の作業が効率的に行えないことが間々生ずること、またこの建柱及びこの建柱上の防霜ファン装置が、景観上で弊害となっていること、等が問題視されている。   As is well known, a tea garden management device has been adopted from the aspect of mechanization and labor saving of the tea garden. In connection with this, the harmful effect of the defrost fan apparatus using the present building pillar and overhead wire is pointed out. In other words, a pillar is erected in a farm such as a tea plantation or tea tree, and the overhead line, etc. stretched toward the building pillar becomes an obstacle when the tea garden management device is moved or operated, and plucking, pruning, and pest control Problems such as the inability to efficiently perform such operations and the fact that the building pillar and the anti-frost fan device on the building pillar are harmful on the landscape are regarded as problems.

そして、問題解消の一環として、本出願人は、低所型の茶園用防霜ファン装置を数件提案している。その一例を概要すると、茶園に埋設した支持部に建柱(支柱)を起伏自在に設け、建柱を起立した状態で、防霜ファンを茶樹上に上昇させて防霜を図り、又建柱を収縮した状態で、防霜ファンを横倒し、防霜ファンを茶樹内に収容する構成である。しかし、この起伏自在の建柱を利用して、防霜ファンを茶樹内に収容するためには、防霜ファンガードが茶樹の高さより、低い状態で収容することが必要となるので、地中にピットを作り、このピットを利用し、防霜ファンを起立した状態で収容する構成、又はピットを作らず防霜ファンを折畳んで(伏して)収容する構成が考えられる。このピットを利用して収容する構成は、手間を要すること、又は防霜ファン駆動用のモータがピットに溜まった雨水中に浸かること等の弊害がある。また防霜ファンを折畳んで収容する構成は、その折畳み方向がこの防霜ファン駆動用のモータ側であるときは、モータが地面に溜まった雨水中に浸かること等の弊害がある。   As part of solving the problem, the present applicant has proposed several low temperature type frost-proof fan devices for tea gardens. An example of this can be summarized as follows: a pillar (post) can be raised and lowered freely on the support part embedded in the tea garden, and the frost-proof fan is raised above the tea tree in the state where the pillar is raised to prevent frost. The frost-proof fan is laid sideways and the frost-proof fan is accommodated in the tea tree in a state where the frosted is contracted. However, in order to house the frost-proof fan in the tea tree using this up and down freestanding pillar, it is necessary to house the frost-proof fan guard in a state lower than the height of the tea tree. A configuration in which a pit is formed and the frost-proof fan is accommodated in an upright state using this pit, or a configuration in which the frost-proof fan is folded (declined) without forming a pit is conceivable. The housing using the pits has problems such as time-consuming work and the fact that the motor for driving the frost-proof fan is immersed in rainwater collected in the pits. Further, the configuration in which the frost-proof fan is folded and accommodated has problems such as the motor being immersed in rainwater collected on the ground when the folding direction is on the motor side for driving the frost-proof fan.

このような問題点の解決策として、文献(1)と文献(2)とが挙げられるので、その概要を説明する。文献(1)は、特開平10−113076の「防霜ファン」である。その概要は、伸縮式のポールの先端に支持部を設け、この支持部に送風機本体に固定された連結部材を首振り及び俯仰調節可能に支持するとともに、この支持部のアーム部と連結部材とで首折り機構を設ける。そのファンの収容時にポールを縮小状態にするとともに、ファンの前面が真下に向くように送風機本体の姿勢を変え、防霜ファン全体が茶畝に収容される構成であり、茶園管理装置の運転の邪魔にならない位置に収容可能としたこと、又は首折り機構と俯仰調節機構を兼用することで、容易な操作を確保すること及び/又は構成の簡素化、低コスト化等を意図すること等を特徴とする。また文献(2)は、特開平10−323130の「植物保護用送風装置」である。その概要は、上部支柱の上方に送風機を備えた植物保護用送風装置で、下部支柱を土中に埋設し、上部支柱を下部支柱内でねじ棒によって上下方向に摺動可能に収容配置し、この送風機を上部支柱起倒可能に取付け、当該送風機の前方を地面に略水平に収容可能とした構成であり、茶刈り作業時に自動茶刈り機の邪魔にならず、かつ、取付け作業が容易な植物保護用送風装置を提供すること、又は支持腕に支軸を介して送風機が起倒可能に取付けられているので、構成の簡素化、低コスト化等を意図すること等を特徴とする。   References (1) and (2) can be cited as solutions for such problems, and an outline thereof will be described. Document (1) is a “frost-proof fan” disclosed in JP-A-10-113076. The outline is that a support part is provided at the tip of the telescopic pole, and the connecting member fixed to the blower main body is supported on the support part so that the swinging and raising / lowering can be adjusted, and the arm part of the supporting part and the connecting member A neck folding mechanism is provided. When the fan is accommodated, the pole is reduced, the orientation of the blower body is changed so that the front of the fan faces directly below, and the entire frost-proof fan is accommodated in the teacup. To be able to be accommodated in an unobtrusive position, or to ensure easy operation and / or to simplify the configuration, reduce costs, etc. by combining the neck folding mechanism and the elevation adjustment mechanism Features. Reference (2) is a “plant protection blower” disclosed in JP-A-10-323130. The outline is a plant protection blower equipped with a blower above the upper support, the lower support is embedded in the soil, and the upper support is accommodated in the lower support so as to be slidable in the vertical direction with a screw rod. The blower is mounted so that the upper column can be tilted up and down, and the front of the blower can be accommodated substantially horizontally on the ground. It does not interfere with the automatic tea-cutting machine during tea-cutting and is easy to install. The present invention is characterized by providing a plant protection blower, or because the blower is attached to the support arm via a support shaft so that the blower can be turned up and down.

前述した文献(1)、(2)は地面にピットを設ける必要がないので、有効性(有益性)を備えている。しかし、防霜ファンの収容時において、この防霜ファンの折畳み及び/又はこの折畳み後における使用の際における防霜ファンの起立等(折畳み・起立とする)に関する具体的な記述と、その機構が開示されていない。従って、この防霜ファンの折畳み等は、手動及び/又は止め具の弛緩・緊締用の工具を利用して行うものと考えられる。   Documents (1) and (2) described above have effectiveness (benefits) because it is not necessary to provide pits on the ground. However, when the frost-proof fan is housed, a specific description about the folding of the frost-proof fan and / or standing up of the frost-proof fan when used after the folding (folding / standing) and its mechanism are Not disclosed. Therefore, it is considered that the frost-proof fan is folded manually and / or using a tool for loosening / tightening the stopper.

以上のように、防霜ファンの折畳み等は、手動及び/又は工具を利用する構成であり、手間を要すること、圃場の全ての防霜ファンを折畳むのに大変な手間を要すること等の問題がある。そして、特に問題となるのに、傾斜地の圃場(傾斜圃場)、高所の圃場(高所圃場)等の悪条件の場合における作業は、極めて大変であること、危険であること等が考えられる。   As described above, folding of the frost-proof fan is a configuration using manual and / or tools, which requires labor, and requires much labor to fold all the frost-proof fans in the field. There's a problem. In particular, work in the case of adverse conditions such as a farm field on a sloping ground (slope farm field) and a farm field at a high altitude (high field farm) is considered to be extremely difficult and dangerous. .

またこの文献(1)における首振り機構は、長い帯板の連結部材28を併設した構成を採用し、この連結部材28で俯角状態の防霜ファンを支持する構成である。従って、強度の確保と、安定性に問題を残すことが考えられる。また文献(2)における首振り機構は、説明及び/又は図番等による説明がなく判然としないが、構成は前記文献(1)に類似すると考えられるので、同様な問題を抱えている。   Further, the swing mechanism in this document (1) employs a configuration in which a long strip connecting member 28 is provided, and this connecting member 28 supports a defrosting fan in a depression angle state. Therefore, it is conceivable to leave problems in securing strength and stability. Further, the swing mechanism in the document (2) is not obvious without explanation and / or explanation with reference to the figure number or the like, but the configuration is considered similar to the document (1), and thus has the same problem.

An arc-shaped kerf 1100 is provided in the side view, and an adjusting stop 12 screwed to the swing base 8 is inserted into the kerf 1100. When the adjustment stopper 12 is unscrewed, the depression adjusting body 11 is moved with the pivot 10 as a fulcrum (this movement is performed using the kerf 1100 as a guide), and the adjustment stopper 12 is screwed in after the movement. Thus, the depression angle adjusting body 11 is adjusted to a predetermined depression angle.

またこの俯角調整体11の上端にはモータベース14が枢軸15を介して可動自在に設けられている。またこの俯角調整体11には側面視して円弧状の切り溝1101が設けられており、この切り溝1101にはガススプリング16の可動側の他端16bが挿嵌されており、この他端16bに前記切り溝1101に沿って可動する構成である。またガススプリング16の一端16aは、この俯角調整体11の下端に枢支されており、この枢支箇所を中心とし、このガススプリング16が収縮する過程で、当該ガススプリング16は可動する。従って、例えば、図3−1〜図3−4に示した如く、建柱1の一部位(最上の建柱1から随時)を降下し、この建柱1及び/又は防霜ファン30を茶樹H内に収容を図る過程で、この防霜ファン30が地面Gに設けられた誘導体G1で押圧される状態となった場合に、例えば、図3−3から図3−4の過程において、防霜ファン30に対する誘導体G1での押圧により、ガススプリング16が押圧されながら、このガススプリング16が収縮される。この収縮する過程で、このガススプリング16の他端16bが、切り溝1101に沿って逃げる。この逃げる動作によりモータベース14の可動を可能とする。そして、このモータベース14の可動は枢軸15を軸とすることで可能となる。即ち、建柱1の収縮(収容)状態で、防霜ファン30を茶樹H内に収容する(伏する)場合は、ガススプリング16の収縮と、このガススプリング16の他端16bの逃げを利用することで、自動的かつ工具を必要とせず、極めて正確で静かに、またワンタッチの動作で行える特徴がある。尚、防霜ファン30を収容状態より、建柱1の伸張と、防霜ファン30の俯角位置への復帰(防霜状態又は起立状態)をする場合は、建柱1が伸張し(最上の建柱1が伸張し)、防霜ファン30に対する押圧が解除されると、ガススプリング16に対する押圧も解除される。これによりガススプリング16が復帰し、順次伸張することで、他端16bが切り溝1101の下端から上端に向かって移動しながら、モータベース14を上昇する。このモータベース14の上昇を介して防霜ファン30が俯角位置に復帰する構成であり、前述の建柱1及び/又は防霜ファン30の収容の動作と、略逆の操作となる。またこの建柱1及び/又は防霜ファン30の復帰の特徴は、前述の例に準ずる。尚、前記ガススプリング16は一例であり、同様な作用をするシリンダー、その他の機構でも可能である。 A motor base 14 is movably provided at the upper end of the depression angle adjusting body 11 via a pivot 15. The depression adjusting body 11 is provided with an arcuate groove 1101 in a side view, and the other end 16b on the movable side of the gas spring 16 is inserted into the groove 1101. 16b is movable along the kerf 1101. Further, one end 16a of the gas spring 16 is pivotally supported by the lower end of the depression adjusting body 11, and the gas spring 16 moves in the process of contracting the gas spring 16 around the pivoted portion. Therefore, for example, as shown in FIGS. 3-1 to 3-4, a part of the building pillar 1 (as needed from the top building pillar 1) is lowered and the building pillar 1 and / or the frost-proof fan 30 is moved to the tea tree. In the process of housing in H, when this frost-proof fan 30 is pressed by the derivative G1 provided on the ground G, for example, in the process of FIGS. The gas spring 16 is contracted while the gas spring 16 is pressed by pressing the frost fan 30 with the derivative G1. In the process of contracting, the other end 16 b of the gas spring 16 escapes along the kerf 1101. This escape operation allows the motor base 14 to move. The motor base 14 can be moved by using the pivot 15 as an axis. That is, when the frost-proof fan 30 is accommodated in the tea tree H in the contracted (accommodated) state of the pillar 1, the contraction of the gas spring 16 and the escape of the other end 16 b of the gas spring 16 are used. By doing so, there is a feature that can be performed automatically and without the need for tools, and can be performed with extremely accurate, quiet and one-touch operation. In addition, when extending the building pillar 1 from the housed state and returning the frost-proof fan 30 to the depression position (frost-proof state or standing state), the building pillar 1 extends (the topmost). When the building pillar 1 expands) and the pressure on the anti-frost fan 30 is released, the pressure on the gas spring 16 is also released. As a result, the gas spring 16 is restored and sequentially extended, so that the motor base 14 is raised while the other end 16b moves from the lower end of the kerf 1101 toward the upper end. The frost-proof fan 30 is returned to the depression position through the elevation of the motor base 14, and the operation is substantially opposite to the operation of housing the building pillar 1 and / or the frost-proof fan 30 described above. In addition, the return characteristics of the building pillar 1 and / or the frost-proof fan 30 are the same as those described above. The gas spring 16 is an example, and a cylinder or other mechanism that performs the same function is also possible.

前記防霜ファン30は、モータベース14に固止したモータ31の図示しない出力軸に固止されており、ファン(羽根)3000とガード3001で構成する。   The anti-frost fan 30 is secured to an output shaft (not shown) of the motor 31 secured to the motor base 14, and includes a fan (blade) 3000 and a guard 3001.

尚、防霜ファン30の防霜効果等は従来例に準ずる。   In addition, the defrosting effect etc. of the defrost fan 30 apply to a conventional example.
