Description

【0001】
【発明が属する技術分野】
本発明は、凍結防止剤散布機に関する。
【0002】
【従来の技術】
冬期間の積雪寒冷地域においては、路面が氷板,圧雪等により摩擦係数が著しく減少し、走行車両にスリップが発生して通行が円滑に行われないため、道路交通確保のため路面上に凍結防止用散布剤の散布が行われている。
【0003】
そして、この種の散布に用いられる凍結防止剤散布機として、車両に散布剤を収納するホッパを設け、このホッパの底部にスクリューコンベヤを配設し、このスクリューコンベヤによりホッパ後部の散布口に散布剤を送って散布する(例えば特許文献1)ものや、前記スクリューコンベヤの代りにベルトコンベヤを用いるものが知られている。
【0004】
ところで、前記凍結防止剤としては、塩化カルシウムや塩などが用いられおり、前記ホッパーは底部に向って狭くなる形状をなし、そのホッパーに凍結防止剤を投入すると、底部側で凍結防止剤が固り易くなり、スクリューコンベヤの上方で凍結防止剤が固まり、スクリューコンベヤへの凍結防止剤の供給が途切れ、凍結防止剤を円滑に散布することができなくなる問題があった。
【0005】
このような問題を考慮して、ホッパー本体内に凍結防止剤攪乱部材をチェーン等の索条物によって揺動自在に吊設してなるものがあり、凍結防止剤を投入、収納しているホッパーを搭載した散布車を走行させて、該ホッパー本体内の凍結防止剤を散布する際に、散布車の走行による振動がホッパー本体内に伝達されて該ホッパー本体内に吊設している凍結防止剤攪乱部材が前後左右或いは上下方向に振動し、凍結防止剤を攪乱させて凍結防止剤が固結するのを防止すると共に開口下端に向かう凍結防止剤の流動性を良好にし、常に円滑な排出が行われる(例えば特許公報2)と記載されている。

【発明が解決しようとする課題】
ところで、前記凍結防止剤として、例えば電気分解により処理したパウダー状のものが用いられる場合があり、この電気分解により得られたものは、微粉末状をなすため、流動性に乏しく、スクリューコンベヤの上方でその凍結防止剤がアーチ状等に固まるブリッジ現象が発生し、上記従来技術の凍結防止剤攪乱部材を用いたとしても、前記ブリッジ部分からスクリューコンベヤ内に凍結防止剤が落下せず、スクリューコンベヤが空転し、凍結防止剤の供給不良を起こすことが予想される。
【0008】
そこで、本発明は、ホッパー内の凍結防止剤を下部のコンベヤに円滑に落下供給することができる凍結防止剤散布機を提供することを目的とする。
【0009】
【課題を解決するための手段】
請求項1の発明は、車体に設けたホッパーと、このホッパー内の凍結防止剤を散布する散布部と、前記ホッパーの下部に横設され該ホッパーの凍結防止剤を前記散布部に送るコンベヤとを備えた凍結防止剤散布機において、前記ホッパー内に縦方向の壁体を設け、この壁体を動かす駆動手段を備えるものである。
【0010】
この請求項1の構成によれば、駆動手段によりホッパー内の壁体を往復駆動や振動駆動し、該ホッパー内の凍結防止剤に、強制的に動きを与えることにより、スクリューコンベヤ上方における凍結防止剤の固結を防止し、円滑な供給が可能となる。しかも、壁体がその面で凍結防止剤に動きを与えるから、凍結防止剤が固結し難くなる。
【0011】
また、請求項2の発明は、前記駆動手段は前記壁体を上下方向に往復駆動するものである。
【0012】
この請求項2の構成によれば、壁体が上下に往復同することにより、凍結防止剤を下方に送る力が得られ、凍結防止剤が下部のコンベヤへと送られる。
【0013】
また、請求項3の発明は、前記壁体の下面に開口部を設けたものである。
【0014】
この請求項3の構成によれば、壁体が上下移動で下方に動く際、下面に開口部があるため、降下時の抵抗が少なく、壁体をスムーズに駆動できる。
【0015】
また、請求項4の発明は、前記ホッパーの側板内面を低摩擦係数面に形成したものである。
【0016】
この請求項4の構成によれば、摩擦係数が低いから、凍結防止剤が内面に付着し難くなるとともに自重で流下し易くなる。
【0017】
また、請求項5の発明は、前記側板を打撃する打撃手段を設けたものである。
【0018】
この請求項5の構成によれば、打撃によりホッパーの側板内面への凍結防止剤の付着を防止できる。
【0019】
【発明の実施形態】
以下、本発明の実施形態を、添付図面を参照して説明する。図1〜図4は本発明の第1実施形態を示し、同図に示すように、凍結防止剤散布機1は、自走式車両の車体2の後部にホッパー3を搭載し、このホッパー3の下部後方に散布部4を設け、前記ホッパー3内に底部には前後方向のスクリューコンベヤ5が設けられ、このホッパー3下部スクリューコンベヤ5によりホッパー3内の凍結防止剤Bが前記散布部4へと送られる。また、ホッパー3の前方に位置して車体2には油圧装置6が搭載され、前期スクリューコンベヤ5は、前記油圧装置6によって回転を制御される油圧モータ7により回転駆動され、その油圧装置6は、車体1に搭載のエンジンを駆動源とする。
【0020】
前記ホッパー3は左右の両側板11,11下部の内面11A,11Aが底部に向かって幅狭になるように斜設されており、両側板11,11の前後を前後板12,12により閉塞し、その上を上板13により閉塞し、該上板13に開閉可能な投入部14を設けている。また、ホッパー3の底板部16はスクリューコンベヤ5の外形に対応して円弧状に形成され、図1に示すように、前後方向において、前記底板部16は下方に向かって僅かに低くなるように傾斜している。
【0021】
前記ホッパー3の内面11Aを低摩擦係数面に形成している。この例では、前記内面11Aにフッ素樹脂などをコーティングした板状の低摩擦係数素材21を貼設することにより前記内面11Aを艇摩擦係数面に形成しており、前記低摩擦係数素材21は内面11Aの傾斜部分に設けられ、その下端21Kは、前記スクリューコンベヤ5の回転中心軸5Aより下方に位置している。
【0022】
また、前記側板11の外面には、打撃手段22が設けられている。この打撃手段22には、空気圧で駆動するエアーハンマーや電磁ハンマーなどが用いられ、例えば数秒間に1回の間隔で前記側板11を打撃するものであり、前記車体2に搭載したコンプレッサー,発電機や蓄電池などの車載駆動源23により駆動する。尚、この車載駆動源23として前記エンジンを用いることもできる。
【0023】
前記ホッパー3内の中央には、振動体たる壁体31が設けられ、この壁体31はホッパー3内の前後に連続し、前記スクリューコンベヤ5の上方に縦設され、その壁体31の前後方向長さは、前記前後板12,12の内面間隔より多少短く形成され、また、その振動壁体31の左右幅は前記スクリューコンベヤ5の幅とほぼ同一である。前記振動壁体31の上部33は上方に向かって先鋭に形成され、上部33の下端に左右の側板34,34を備え、図1に示すように、それら左右の側板34,34の間には板状の横リブ35,35A,35Bが上部,中部,下部に配置され、それら横リブ35,35A,35Bは左右の側板34,34を連結するものであり、図2に示すように、壁体31の前後及び中央にそれぞれ横リブ35,35A,35Bが配置され、その壁体31の下面には、左右の側板34,34と横リブ35B,35B,35Bとの間に開口部36が形成されている。
【0024】
前記壁体31のその下部中央内に角パイプなどからなる固定桟32が遊挿され、この固定桟32の前後はホッパー3の前後板12,12に固定され、前記固定桟32の上に駆動手段たる伸縮シリンダ37が立設され、この伸縮シリンダ37の上部に前後方向の横杆38を連結し、この横杆38を前記横リブ35,35,35に固定している。尚、伸縮シリンダ37は油圧や空気圧などで駆動するタイプのものを用いることができ、例えば、50〜150mmのストロークで伸縮するから、壁体31が50〜150mmのストロークで昇降する。また、駆動手段である伸縮シリンダ37の動力源も前記車載動力源23やエンジンなどの車載のものを用いることができる。
【0025】
そして、図3に示すように、振動壁体31の前後及び中央にそれぞれ前記伸縮シリンダ37,37,37が配置され、これら隣り合う伸縮シリンダ37,37,37の前後方向中央位置に前記打撃手段22,22が配置されている。
【0026】
また、図4に示すように、前記側板34の外面には横方向の突片39,39を上下方向ほぼ等間隔で設けている。尚、図3では突片39を図示省略しているが、その突片39は側板34の前後方向長さとほぼ同一長さであり、必要に応じて長さ方向の途中で分割してもよい。
【0027】
次に、前記構成につき、その作用を説明すると、投入部14から凍結防止剤Bをホッパー3内に投入すると、その凍結防止剤Bはホッパー3をほぼ左右に2分する壁体31の左右の空間にそれぞれ充填される。この場合、スクリューコンベヤ5の上方には壁体31が位置し、開口部36から凍結防止剤Bの一部が壁体31内に進入するが、スクリューコンベヤの上方に置ける凍結防止剤Bの堆積荷重は従来に比べて小さく、スクリューコンベヤ5の真上で凍結防止剤Bに固結部分が発生することがない。
【0028】
そして、傾斜した内面11Aが低摩擦係数面に形成されているから、内面11Aに内部の凍結防止剤Bが付着し難く、その傾斜に沿って下方に流れ落ち易くなっている。また、打撃手段22により側板11に打撃を加えることにより、側板11に近傍の凍結防止剤Bが動かされて良好に落下する。しかも、駆動手段である伸縮シリンダ37を駆動して壁体31を上下往復駆動することにより、凍結防止剤Bに面で動きを加えることができ、内面11Aと側板34の下方間における凍結防止剤Bのブリッジ現象を防止することができ、その上下往復動により凍結防止剤Bがスクリューコンベヤ7に案内される。そして、上下往復動において、壁体31が降下する際、その下面は塞がれておらず、開口部36が形成されているため、スムーズな降下が可能となる。
【0029】
このように本実施形態では、請求項1に対応して、車体2に設けたホッパー3と、このホッパー3内の凍結防止剤Bを散布する散布部4と、ホッパー3の下部に横設され該ホッパー3の凍結防止剤Bを散布部4に送るコンベヤたるスクリューコンベヤ5とを備えた凍結防止剤散布機において、ホッパー3内に縦方向の壁体31を設け、この壁体31を動かす駆動手段たる伸縮シリンダ37を備えるから、伸縮シリンダ37によりホッパー3内の壁体31を上下往復駆動し、該ホッパー3内の凍結防止剤Bに強制的に動きを与えることにより、スクリューコンベヤ5上方における凍結防止剤Bの固結を防止し、円滑な供給が可能となる。また、しかも、壁体31がその面で凍結防止剤Bに動きを与えるから、凍結防止剤Bが固結し難くなる。
【0030】
また、このように本実施形態では、請求項2に対応して、前記駆動手段は壁体31を上下方向に往復駆動する伸縮シリンダ37であり、壁体31が上下に往復同することにより、凍結防止剤Bを下方に送る力が得られ、凍結防止剤Bが下部のコンベヤへと送られる。
【0031】
また、このように本実施形態では、請求項3に対応して、壁体31の下面に開口部36を設けたから、壁体31が上下移動で下方に動く際、下面に開口部36があるため、降下時の抵抗が少なく、壁体31をスムーズに駆動できる。
【0032】
また、このように本実施形態では、請求項4に対応して、ホッパー3の側板11の内面11Aを低摩擦係数面に形成したから、凍結防止剤Bが内面11Aに付着し難くなるとともに自重で流下し易くなる。
【0033】
また、このように本実施形態では、請求項5に対応して、側板11を打撃する打撃手段22を設けたから、打撃によりホッパーの側板11内面11Aへの凍結防止剤Bの付着を防止できる。
【0034】
また、実施形態上の効果として、壁体31がスクリューコンベヤ5の幅とほぼ同一であるから、スクリューコンベヤ5の真上で凍結防止剤Bに固結部分が発生することを防止できる。また、壁体31内に駆動手段たる伸縮シリンダ37を内蔵したから、構造簡易で、ホッパー3への取り付けも容易となり、同時に壁体31はほぼ中空構造であるから、軽量となり、駆動手段も小型で済む。さらに、壁面34に突片39を設けたから、内部の凍結防止剤Bに効率よく振動を伝えることができる。また、ホッパー3の前後方向において、駆動手段である伸縮シリンダ37,37の間に打撃手段22を配置したから、振動と打撃により効率よく内部の凍結防止剤Bに動きを与えることができる。
【0035】
図5は本発明の第2実施形態を示し、上記第1実施形態と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例の壁体31は上部33の頂部に枢着部41を設け、この枢着部41を中心として左右の側板34,34が開閉可能に形成され、左右の側板34,34は略へ字型のリンク片36により連結され、それら側板34,34の下部側を開閉するシリンダなどの伸縮駆動装置42が振動壁体31内に設けられている。尚、この例では、側板34,34が開閉するから、前記横リブ35,35A,35Bは用いられておらず、横杆38を枢着部41に連結することによって、伸縮シリンダ37の伸縮により壁体31が上下往復動する。
【0036】
したがって、左右の側板34,34を開閉駆動することにより、スクリューコンベヤ5の上方における凍結防止剤Bのブリッジ現象を防止することができる。また、壁体31を降下する際に側板34,34の下部を狭めるようにすれば、下方への降下が容易となる。このように、駆動手段たる伸縮シリンダ37による上下動きと、開閉駆動手段である伸縮駆動装置42による開閉動作を組み合わせることにより、凍結防止剤Bを効率よく下方に案内できる。
【0037】
図6は本発明の第3実施形態を示し、上記第1実施形態と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例では、ホッパー3の下部に開口部17を設け、この開口部17の下部に、コンベヤたるベルトコンベヤ51を設け、このベルトコンベヤ51は無端状ベルトを有するものであって、開口部17から落下した凍結防止剤Bを散布部5に送るものである。
【0038】
このように本実施形態では、車体2に設けたホッパー3と、このホッパー3内の凍結防止剤Bを散布する散布部4と、ホッパー3の下部に横設され該ホッパー3の凍結防止剤Bを散布部4に送るコンベヤたるベルトコンベヤ51とを備えた凍結防止剤散布機において、ホッパー3内に縦方向の壁体31を設け、この壁体31を動かす駆動手段たる伸縮シリンダ37を備えるから、上記各実施形態と同様な作用,効果を奏する。
【0039】
尚、本発明は上記実施例に限定されるものではなく本発明の要旨の範囲内において種々の変形実施が可能である。例えば、側板の内面に直接摩擦の小さい樹脂などをコーティングすることにより、前記内面を低摩擦係数面に形成してもよい。の底部が底板部35により閉塞されている。また、駆動手段はエヤーや電気を動力源として振動を発生するものや偏心ウエートの回転やクランク機構の回転などにより振動を発生するものを用いることもでき、好ましくは壁体を上下方向に振動するものが用いられ、この場合の振動には、壁体を揺り動かす揺動も含まれる。
【0040】
【発明の効果】
請求項1の発明は、車体に設けたホッパーと、このホッパー内の凍結防止剤を散布する散布部と、前記ホッパーの下部に横設され該ホッパーの凍結防止剤を前記散布部に送るコンベヤとを備えた凍結防止剤散布機において、前記ホッパー内に縦方向の壁体を設け、この壁体を動かす駆動手段を備えるものであり、ホッパー内の凍結防止剤を下部のスクリューコンベヤに円滑に落下供給することができる。
【0041】
また、請求項2の発明は、前記駆動手段は前記壁体を上下方向に往復駆動するものであり、ホッパー内の凍結防止剤を下部のスクリューコンベヤに円滑に落下供給することができる。
【0042】
また、請求項3の発明は、前記壁体の下面に開口部を設けたものであり、ホッパー内の凍結防止剤を下部のスクリューコンベヤに円滑に落下供給することができる。
【0043】
また、請求項4の発明は、前記ホッパーの側板内面を低摩擦係数面に形成したものであり、ホッパー内の凍結防止剤を下部のスクリューコンベヤに円滑に落下供給することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cryoprotectant sprayer.
[0002]
[Prior art]
In the cold winter area, the coefficient of friction on the road surface is significantly reduced due to ice sheets, snow compaction, etc., and slipping occurs on the running vehicle, making it difficult to pass smoothly. Spraying of preventive spraying is being carried out.
[0003]
As a deicing agent sprayer used for this type of spraying, a hopper for storing the spraying agent is provided in the vehicle, a screw conveyor is disposed at the bottom of the hopper, and the screw conveyor sprays the spraying agent at the rear of the hopper. There have been known those which send and spray the agent (for example, Patent Document 1) and those which use a belt conveyor in place of the screw conveyor.
[0004]
By the way, calcium chloride, salt, or the like is used as the antifreeze, and the hopper has a shape that narrows toward the bottom. When the antifreeze is put into the hopper, the antifreeze is solidified on the bottom side. The antifreeze agent solidifies above the screw conveyor, the supply of the antifreeze agent to the screw conveyor is interrupted, and the antifreeze agent cannot be sprayed smoothly.
[0005]
In consideration of such a problem, there is a hopper in which a deicing agent disturbing member is hung by a cable such as a chain in a hopper body so as to swing freely. When the spraying vehicle equipped with is run to spray the antifreezing agent in the hopper body, the vibration caused by the running of the spraying vehicle is transmitted into the hopper body and the antifreeze suspended in the hopper body. The agent disturbing member vibrates back and forth, left and right or up and down, disturbs the antifreeze and prevents the antifreeze from solidifying, and improves the flowability of the antifreeze toward the lower end of the opening, ensuring smooth discharge. (For example, Patent Publication 2).

[Problems to be solved by the invention]
By the way, as the antifreezing agent, for example, a powdery substance treated by electrolysis may be used, and the substance obtained by this electrolysis is in the form of a fine powder, has poor fluidity, and has a low screw conveyor. A bridge phenomenon in which the deicing agent hardens in an arch shape or the like occurs at the upper portion, and even if the above-described prior art deicing agent disturbing member is used, the deicing agent does not fall into the screw conveyor from the bridge portion, and the screw It is anticipated that the conveyor will run idle, causing defective supply of the deicing agent.
[0008]
Therefore, an object of the present invention is to provide a cryoprotectant sprayer capable of smoothly dropping and supplying a cryoprotectant in a hopper to a lower conveyor.
[0009]
[Means for Solving the Problems]
The invention according to claim 1 includes a hopper provided on the vehicle body, a spraying unit for spraying the antifreezing agent in the hopper, and a conveyor which is provided below the hopper and sends the antifreezing agent of the hopper to the spraying unit. And a vertical wall is provided in the hopper, and a driving means for moving the wall is provided.
[0010]
According to the first aspect of the present invention, the wall inside the hopper is reciprocally driven or vibrated by the driving means, and the anti-freezing agent in the hopper is forcibly moved to prevent the freezing above the screw conveyor. It prevents the caking of the agent and enables a smooth supply. In addition, since the wall gives the antifreeze movement on its surface, the antifreeze hardly hardens.
[0011]
According to a second aspect of the present invention, the driving means reciprocates the wall body in a vertical direction.
[0012]
According to the configuration of the second aspect, the wall body reciprocates up and down, whereby a force for sending the antifreeze downward is obtained, and the antifreeze is sent to the lower conveyor.
[0013]
According to a third aspect of the present invention, an opening is provided on the lower surface of the wall.
[0014]
According to the configuration of the third aspect, when the wall body moves downward by vertical movement, since the opening is provided on the lower surface, the resistance at the time of falling is small, and the wall body can be driven smoothly.
[0015]
According to a fourth aspect of the present invention, the inner surface of the side plate of the hopper is formed with a low friction coefficient surface.
[0016]
According to the configuration of the fourth aspect, since the coefficient of friction is low, the antifreezing agent hardly adheres to the inner surface and flows down by its own weight.
[0017]
The invention according to claim 5 is provided with a striking means for striking the side plate.
[0018]
According to the configuration of the fifth aspect, it is possible to prevent the freezing agent from adhering to the inner surface of the side plate of the hopper due to the impact.
[0019]

Further, since the telescopic cylinder 37 serving as a driving means is built in the wall 31, the structure is simple and the mounting to the hopper 3 is easy. At the same time, the wall 31 is almost hollow, so that the weight is small and the driving means is small. Only needs to be done. Furthermore, since the projection 39 is provided on the wall surface 34, vibration can be efficiently transmitted to the antifreezing agent B inside. Further, since the striking means 22 is disposed between the telescopic cylinders 37, 37 as the driving means in the front-rear direction of the hopper 3, it is possible to efficiently move the anti-freezing agent B inside by vibrating and striking.
