Description
本考案は疎水材投入装置に関し、更に詳しくは、暗渠排水工事等で埋設される排水管の上部にあらゆる種類の疎水材を投入するための電動式の疎水材投入装置に関する。 The present invention relates to a hydrophobic material charging device, and more particularly to an electric hydrophobic material charging device for charging all kinds of hydrophobic material into an upper part of a drain pipe buried in underdrainage or the like.
暗渠排水工事では、排水管を埋設するための掘削溝（暗渠）の内部であり該排水管の上部に疎水材を投入して、土中の水が該排水管に流入し易いようにしている。従来、掘削溝（暗渠）に疎水材を投入する方法としては、人手に頼るものが多かった。しかし、圃場数の増加や圃場の面積の増加に伴い、手作業による疎水材の投入では多くの人手が必要であり、人件費が高くつく、時間がかかる等という問題があった。 In underdrain drainage work, a hydrophobic material is placed inside the excavation groove (underdrain) for burying the drain pipe so that water in the soil can easily flow into the drain pipe. . Conventionally, as a method for introducing a hydrophobic material into the excavation groove (underdrain), there are many methods that rely on human hands. However, with the increase in the number of fields and the area of the fields, there are problems in that the manual introduction of the hydrophobic material requires a lot of manpower, which increases labor costs and takes time.
そこで、現在では広大な圃場を一定の作業者により効率良く作業を行うために、上記の人力施工から機械施工に移行しつつある。疎水材の投入を機械化する方法としては、例えば、ダンプカー等の荷台に疎水材を収容し、その荷台を傾斜させつつ疎水材を掘削溝に供給する方法が知られている。 Therefore, at present, in order to perform work efficiently on a large field by a certain worker, the above-described manual construction is shifting to mechanical construction. As a method for mechanizing the injection of the hydrophobic material, for example, a method is known in which the hydrophobic material is accommodated in a loading platform such as a dump truck and the hydrophobic material is supplied to the excavation groove while the loading platform is inclined.
しかしながら、この方法では、ダンプカー等の荷台の傾斜角度の調整のみによって一定量の疎水材を掘削溝に供給することは極めて困難であり、多くの疎水材が一気に落ちることもある一方で、荷台の下方部に疎水材が詰まってしまう場合があった。 However, with this method, it is extremely difficult to supply a certain amount of hydrophobic material to the excavation groove only by adjusting the inclination angle of the loading platform such as a dump truck, and while many hydrophobic materials may drop at a stretch, In some cases, the lower portion was clogged with a hydrophobic material.
そこで、特許文献１には、掘削溝の真上に位置し昇降調整が可能な疎水材充填部を有する疎水材充填装置に関する技術が記載されおり、そこでは疎水材が充填された内部ホッパーの傾斜を調節したり、シャッター開口部の間隙を調節したりして、疎水材が掘削溝に落ちるような工夫がなされている。しかしながら、この装置は極めて大がかりなものであり、しかも疎水材充填装置を設置した専用の車両が必要であった。しかも、コンベアを使用していないために、掘削溝の上又は掘削溝の近傍をその専用の車両が移動する必要があり、安全性にも問題があった。 Therefore, Patent Document 1 describes a technique related to a hydrophobic material filling device that has a hydrophobic material filling portion that is positioned directly above the excavation groove and can be adjusted up and down, in which the inclination of the internal hopper filled with the hydrophobic material is described. The device has been devised so that the hydrophobic material falls into the excavation groove by adjusting the gap or adjusting the gap of the shutter opening. However, this device is extremely large, and a dedicated vehicle equipped with a hydrophobic material filling device is required. In addition, since no conveyor is used, it is necessary for the dedicated vehicle to move on or in the vicinity of the excavation groove, which causes a problem in safety.
特許文献２には、走行方向に対し横方向に疎水材を投下するためのスクリューコンベアを有し、そのコンベア上に荷台の傾斜によって疎水材を供給する埋め戻し材投入車が記載されている。しかしながら、この技術では、スクリューコンベア上に一定速度で荷台から疎水材を供給することはできず、更にはスクリューコンベアでは移送できる疎水材の種類が限定されるという問題もあった。しかも、コンベア搭載の専用車を用いなくてはいけないという問題点が依然としてあった。 Patent Document 2 describes a backfilling material charging vehicle that has a screw conveyor for dropping a hydrophobic material in a direction transverse to the traveling direction, and supplies the hydrophobic material on the conveyor by tilting the loading platform. However, this technique has a problem that the hydrophobic material cannot be supplied from the loading platform at a constant speed onto the screw conveyor, and furthermore, the types of hydrophobic materials that can be transferred by the screw conveyor are limited. Moreover, there is still a problem that a special vehicle equipped with a conveyor has to be used.
特許文献３には、傾斜可能な可動ホッパーや特殊なスクリューコンベアによって、疎水材の目詰まりを防止しつつ疎水材を投入する技術が開示されているが、装置が大掛かりな上に、スクリューコンベアでは移送できる疎水材の種類が限定され、しかも、コンベア搭載の専用車を用いなくてはいけないという問題点があった。 Patent Document 3 discloses a technique of introducing a hydrophobic material while preventing clogging of the hydrophobic material by a movable hopper capable of tilting or a special screw conveyor. The types of hydrophobic materials that can be transported are limited, and there is a problem that a dedicated vehicle equipped with a conveyor must be used.
特許文献４には、疎水材の種類が限定されないようにベルトコンベアを移送手段として用い、疎水材を移送手段の上にバイブレーターを用いて振動を与えつつ供給することによって、一定量の疎水材を供給できる技術が開示されているが、疎水材を供給は依然としてキャリアダンプの荷台の傾斜によるものであり、安定供給に欠けるものであり、更にはバイブレーターでは破砕や解砕ができないために、大きな疎水材はそのまま掘削溝に投入することになり、排水性能等に支障をきたすものであった。 In Patent Document 4, a belt conveyor is used as transfer means so that the type of hydrophobic material is not limited, and a certain amount of hydrophobic material is supplied by supplying the hydrophobic material on the transfer means while vibrating using a vibrator. Although the technology that can be supplied is disclosed, the supply of the hydrophobic material is still due to the inclination of the carrier dump bed, lacks a stable supply, and furthermore, the vibrator cannot be crushed or crushed, so that a large hydrophobic The material was put into the excavation groove as it was, and it impeded drainage performance.
このように、上記何れの技術も、疎水材を一定量投入しようとしたものではあるが、何れも疎水材の安定供給性が依然として不十分であり、更には、供給装置やコンベアが既設された車両を用いざるを得なかったりして、実質的には専用の車両が必要であり、圃場等を使用していない時期にしか稼働できないため一般に稼働率が低い疎水材投入装置の使用形態としては、専用車両は極めてコスト的に不利なものであった。 As described above, each of the above techniques is intended to introduce a certain amount of the hydrophobic material, but the stable supply of the hydrophobic material is still insufficient, and further, a supply device and a conveyor are already installed. As a usage form of the hydrophobic material charging device, which generally has a low operation rate, it is necessary to use a vehicle, and a dedicated vehicle is practically necessary, and it can be operated only when the field is not used. The dedicated vehicle was extremely costly.
更には、荷台の傾斜等の駆動に油圧を用いるものについては、そこで使用する油が圃場等に浸み込み環境を汚染することが懸念されており、行政の指導も厳しくなっているが、それにも十分には対応できないでいた。 Furthermore, for those that use hydraulic pressure to drive the platform, etc., there is a concern that the oil used there will infiltrate the field and contaminate the environment, and administrative guidance has become strict. Couldn't respond enough.
本考案は上記背景技術に鑑みてなされたものであり、その課題は、種々の車両の荷台に脱着が可能であるため専用車両を必要とせず、あらゆる疎水材を掘削溝（暗渠）に極めて均一に投入できる疎水材投入装置を提供することにある。 The present invention has been made in view of the above-mentioned background art, and its problem is that it can be attached to and detached from the loading platform of various vehicles, so no special vehicle is required, and any hydrophobic material is extremely uniform in the excavation groove (underdrain). An object of the present invention is to provide a hydrophobic material feeding device that can be loaded into a container.
本考案者は、上記の課題を解決すべく鋭意検討を重ねた結果、特定の破砕手段を有し特定の構造を有する疎水材収納容器を用いることによって、あらゆる疎水材を好適サイズにして、その下に位置するコンベア上に一定量で供給でき、その結果として掘削溝に疎水材を均一に投入できることを見出した。また、該疎水材収納容器は、ダンプカー等の荷台に容易に脱着可能にでき、専用車両を用いる必要をなくせることを見出して本考案を完成するに至った。 As a result of intensive studies to solve the above-mentioned problems, the present inventor made every hydrophobic material suitable size by using a hydrophobic material storage container having a specific crushing means and a specific structure. It has been found that a constant amount can be supplied onto the conveyor located below, and as a result, the hydrophobic material can be uniformly introduced into the excavation groove. Further, the present inventors have completed the present invention by finding that the hydrophobic material storage container can be easily attached to and detached from a loading platform such as a dump truck and can eliminate the necessity of using a dedicated vehicle.
すなわち、本考案は、排水管を埋設するための掘削溝の内部であり該排水管の上部に疎水材を投入する装置であって、該疎水材を収納する疎水材収納容器、該疎水材収納容器の下に位置し該疎水材収納容器から落下する疎水材を該掘削溝まで移送するコンベア、及び、発電機を少なくとも有し、該疎水材収納容器のホッパーの出口部分上部に、該ホッパーを横断するように、破砕羽が設置されたシャフトが設けられ、該発電機からの電力によって該シャフトが回転して、疎水材を破砕しつつ該コンベアの上に疎水材を一定量ずつ供給できるようになっていることを特徴とする疎水材投入装置を提供するものである。 That is, the present invention is an apparatus for introducing a hydrophobic material into an excavation groove for embedding a drain pipe and to the upper part of the drain pipe, the hydrophobic material storage container for storing the hydrophobic material, and the hydrophobic material storage A conveyor that is located under the container and that transfers the hydrophobic material falling from the hydrophobic material storage container to the excavation groove, and a generator, and the hopper is disposed above the outlet portion of the hopper of the hydrophobic material storage container. A shaft provided with crushing blades is provided so as to cross, and the shaft is rotated by the electric power from the generator so that the hydrophobic material can be supplied onto the conveyor in a certain amount while crushing the hydrophobic material. The present invention provides a hydrophobic material feeding device characterized by the above.
また、本考案は、上記の疎水材投入装置を用いた暗渠工事で埋設されたものであることを特徴とする排水管を提供するものである。 In addition, the present invention provides a drain pipe characterized in that it is buried in a culvert using the above-described hydrophobic material charging device.

According to the present invention, the above problems are solved to solve the problem,
(1) Since the supply of the hydrophobic material onto the conveyor does not depend on the natural fall using the inclination of the loading platform as in the prior art, a certain amount of the hydrophobic material can be fundamentally supplied onto the conveyor.
(2) Since it can be easily attached to and detached from the loading platform of general purpose vehicles such as dump trucks, a dedicated vehicle is prepared for underdrain construction that can only be used when the field is not used and the operating rate is generally low. This eliminates the need to keep costs and reduces costs.
(3) Since a dedicated vehicle is not used, it is possible to work in any field.
(4) Since the crushing means is provided at the upper part of the outlet portion of the hopper of the hydrophobic material storage container, the hydrophobic material is not clogged, and the hydrophobic material is crushed on the conveyor in a certain amount while crushing the hydrophobic material. Can supply.
(5) The present invention can be applied to all hydrophobic materials having different sizes, hardnesses, shapes, types, aggregation states, and the like.
(6) Since a generator is essential and the shaft of the crushing means is rotated by the electric power from the generator, the hydrophobic material can be supplied while being crushed, and there is no concern about environmental pollution due to oil leakage because hydraulic pressure is not used. is there.
(7) Since the supply of the hydrophobic material is not a hydraulic system and the crushing means, the conveyor, and the like are driven by electricity, remote operation is possible even while driving the vehicle.
(8) Since not only crushing means but all driving can be performed with electric power instead of hydraulic pressure, maintenance of a hydraulic pump or the like is unnecessary, and work can be started immediately and easily after carrying on site. It also saves time for turning off the hydraulic pressure.
(9) The distance of the excavation groove where the hydrophobic material can be introduced in one day can be extended. Specifically, for example, what was conventionally 700 m / day can be extended to 1200-1300 m / day.
(10) Since the hydrophobic material storage container, the conveyor and the generator, which are essential members of the hydrophobic material charging device of the present invention, are all separable, they are all stored within the width of the transport truck for transportation and are optimally operated It can be installed by pulling it out at an arbitrary distance so that it can be. As for transportation trucks and the like that transport ordinary roads, for example, a two-ton car can be sufficiently transported.
(11) Since a simple hydrophobic material storage container is used, a winter electric heater for preventing freezing of the hydrophobic material is installed on the wall surface of the hydrophobic material storage container, and a manual device for adjusting the discharge amount is installed below the hydrophobic material storage container. Installation of incidental equipment such as installation is extremely easy.
以下、本考案について説明するが、本考案は以下の具体的形態に限定されるものではなく、本考案の技術的思想の範囲内で任意に変形することができる。 Hereinafter, although this invention is demonstrated, this invention is not limited to the following specific forms, In the range of the technical idea of this invention, it can deform | transform arbitrarily.
本考案の疎水材投入装置は、暗渠工事において、暗渠に疎水材を投入するためのものである。すなわち、排水管を埋設するための掘削溝（暗渠）の内部であり該排水管の上部に、水の浸透促進、排水管に開けられた水通過穴の詰まりを回避するため等に用いる疎水材を投入する装置である。 The hydrophobic material feeding device of the present invention is for feeding a hydrophobic material into a culvert during culvert construction. That is, a hydrophobic material that is used inside the excavation groove (underdrain) for embedding the drain pipe and for promoting the penetration of water in the upper part of the drain pipe and avoiding clogging of the water passage hole opened in the drain pipe It is a device to input.
図２に、本考案の疎水材投入装置を用いる暗渠排水の断面概略を示す。具体的数値には特に限定はないが、例えば、幅約２０〜４０ｃｍ、深さ約０．８〜１．２ｍ程度の掘削溝の下に排水管を置き、そこに疎水材を投入する。なお、排水管の直径は通常は６０〜１２０ｍｍである。最後に埋め戻し土を深さ約１５〜３０ｃｍ程入れて完成する。通常は、このような掘削溝を約５〜約１２ｍおきに平行に通して排水させる。 In FIG. 2, the cross-sectional outline of the underdrain drainage using the hydrophobic material injection | throwing-in apparatus of this invention is shown. Specific numerical values are not particularly limited. For example, a drain pipe is placed under a digging groove having a width of about 20 to 40 cm and a depth of about 0.8 to 1.2 m, and a hydrophobic material is put therein. In addition, the diameter of a drain pipe is 60-120 mm normally. Finally, the backfill is filled with a depth of about 15-30 cm. Usually, such digging grooves are drained through about 5 to about 12 m in parallel.
本考案の疎水材投入装置は、少なくとも、（ａ）疎水材を収納する疎水材収納容器、（ｂ）該疎水材収納容器の下に位置し該疎水材収納容器から落下する疎水材を該掘削溝まで移送するコンベア、及び、（ｃ）発電機を有している。 The hydrophobic material charging device according to the present invention includes at least (a) a hydrophobic material storage container for storing a hydrophobic material, and (b) excavating a hydrophobic material positioned below the hydrophobic material storage container and falling from the hydrophobic material storage container. It has a conveyor that transfers to the groove, and (c) a generator.
図１に、上記した（ａ）疎水材収納容器３１、（ｂ）コンベア４１及び（３）発電機５１を汎用車両１７であるクローラーダンプに設置した全体斜視図を示す。疎水材収納容器３１は、錐体を逆にした形状のホッパー３１ａと、要すれば疎水材収納容器３１の収納量を増加させるための垂直板３１ｂからなっており、垂直板３１ｂは、ホッパー３１ａの上縁の全体に蝶番３１ｃで固定されて設けられている。垂直板３１ｂは、あおり板のように、輸送時には蝶番３１ｃを用いて、ホッパー３１ａの外側に倒せるようになっており、作業時には疎水材１１の収納量を増やせると共に、輸送時には全高を低くしてコンパクトに畳めるようになっている。 FIG. 1 shows an overall perspective view in which the above-described (a) hydrophobic material storage container 31, (b) conveyor 41, and (3) generator 51 are installed on a crawler dumper that is a general-purpose vehicle 17. The hydrophobic material storage container 31 includes a hopper 31a having an inverted cone shape and, if necessary, a vertical plate 31b for increasing the storage amount of the hydrophobic material storage container 31, and the vertical plate 31b is a hopper 31a. It is fixed to the entire upper edge by a hinge 31c. The vertical plate 31b can be tilted to the outside of the hopper 31a using a hinge 31c at the time of transportation, like a tilt plate, and can increase the storage amount of the hydrophobic material 11 at the time of operation and lower the overall height at the time of transportation. It can be folded compactly.
図１は作業時の図であるので、疎水材収納容器３１の下部の疎水材１１の出口の下には、コンベア４１が設置されている。作業時のコンベア４１は、車両の進行方向に対して直角方向に張り出しており、車両が掘削溝１２に沿って平行に移動しながら、疎水材１１をコンスタントに掘削溝１２中に投下できるようになっている。 Since FIG. 1 is a figure at the time of work, the conveyor 41 is installed under the exit of the hydrophobic material 11 in the lower part of the hydrophobic material storage container 31. The conveyor 41 at the time of working projects in a direction perpendicular to the traveling direction of the vehicle so that the hydrophobic material 11 can be constantly dropped into the excavation groove 12 while the vehicle moves in parallel along the excavation groove 12. It has become.
コンベア４１は特に限定はないが、ベルトコンベアであることが、あらゆる種類の疎水材１１を移送できるために好ましい。従来の疎水材投入装置では、ベルトコンベアは、疎水材１１が砂利類の場合は使用できるが、木材チップ、セラミックチップ等、凝集していて一気に大量に落下する恐れのあるものには不適であり、一方、スクリューコンベアは、凝集していて一気に大量に落下する恐れのあるものでも、一定の輸送量にし易く使用できるが、砂利等の硬いものでは使用できなかった。従って、従来の疎水材投入装置では、使用できる疎水材と使用できない疎水材があり、疎水材の種類が変わる度に、コンベア４１を取り換える必要があった。しかも、コンベア４１が既に取り付けてある専用車両ではそれもできなかった。 The conveyor 41 is not particularly limited, but is preferably a belt conveyor because all kinds of the hydrophobic material 11 can be transferred. In the conventional hydrophobic material feeding device, the belt conveyor can be used when the hydrophobic material 11 is gravel, but it is not suitable for wood chips, ceramic chips, etc. that may be agglomerated and fall in large quantities at once. On the other hand, the screw conveyor, which is agglomerated and may fall in a large amount at once, can be used easily with a constant transport amount, but it cannot be used with hard materials such as gravel. Therefore, in the conventional hydrophobic material feeding apparatus, there are hydrophobic materials that can be used and hydrophobic materials that cannot be used, and it is necessary to replace the conveyor 41 every time the type of the hydrophobic material changes. Moreover, this cannot be achieved with a dedicated vehicle to which the conveyor 41 is already attached.
図１では、コンベア４１は汎用車両１７から左側に直角に張り出されている。これによって、汎用車両１７が圃場等を移動中に、並行している掘削溝１２内に脱輪する可能性がなくなり安全性が増す。本考案の疎水材投入装置を輸送トラック等に載せて一般道を圃場等に向けて輸送中は、コンベア４１は図１においては右側に手動等で収納でき、輸送トラック等の車幅内に収めることができる。圃場等に到着して、汎用車両１７に載せるときに、コンベア４１を図１のように手動で左側に移動して用いることができる。 In FIG. 1, the conveyor 41 protrudes from the general-purpose vehicle 17 to the left at a right angle. As a result, there is no possibility that the general-purpose vehicle 17 is derailed into the parallel excavation grooves 12 while moving in the field or the like, and safety is increased. When the hydrophobic material charging device of the present invention is mounted on a transport truck or the like and the general road is transported toward a field or the like, the conveyor 41 can be manually stored on the right side in FIG. 1 and stored within the width of the transport truck or the like. be able to. When arriving at a farm or the like and placing it on the general-purpose vehicle 17, the conveyor 41 can be manually moved to the left as shown in FIG.
本考案の疎水材投入装置は、疎水材収納容器３１のホッパー３１ａの出口部分上部に、疎水材１１の破砕手段３２があり、疎水材１１を破砕しつつコンベア４１の上に疎水材１１を一定量ずつ供給できるようになっているので、従来はベルトコンベアには不向きであった「もみがら、木材チップ、セラミックチップ等、水を含むと凝集していて一気に大量に落下する恐れのある疎水材」、「ホタテ貝殻、カキ貝殻等、粉砕が必要な疎水材」等でもベルトコンベアが使用でき、また、粉石、ビリ砂利、火山礫等の硬い砂利類は、ベルトコンベアがもとより使用できるので、結果として、あらゆる種類の疎水材１１に本考案の疎水材投入装置は適用できる。 The hydrophobic material charging apparatus of the present invention has a crushing means 32 for the hydrophobic material 11 at the upper part of the outlet portion of the hopper 31a of the hydrophobic material storage container 31, and the hydrophobic material 11 is fixed on the conveyor 41 while crushing the hydrophobic material 11. Since it can be supplied in quantities, it was previously unsuitable for belt conveyors. “Hydrophore, wood chips, ceramic chips, etc., a hydrophobic material that can agglomerate and fall in large quantities when it contains water. "Belt conveyors such as scallop shells, oyster shells and other hydrophobic materials that need to be crushed" can be used, and hard gravel such as powdered stone, billi gravel, volcanic gravel can be used from the belt conveyor. As a result, the hydrophobic material charging device of the present invention can be applied to all types of hydrophobic material 11.
疎水材１１を確実に掘削溝１２内に投下できるように、コンベア４１の末端、掘削溝１２のほぼ真上には、図１のように疎水材導入部材４２が設けることが好ましい。 In order to ensure that the hydrophobic material 11 can be dropped into the excavation groove 12, it is preferable to provide a hydrophobic material introduction member 42 at the end of the conveyor 41 and almost directly above the excavation groove 12 as shown in FIG. 1.
主に、破砕手段３２において破砕羽３２ｂが設置されたシャフト３２ａを回転させるため、コンベア４１を作動させるため、要すれば疎水材１１の凍結防止用に冬季用電熱ヒーター３４を作動させるために発電機５１が必須である。本考案では油圧を用いず電力で全て作動するので、油漏れによる圃場等の土壌の汚染がなく、この点について厳しくなった行政指導にも対応可能である。また、油圧方式を用いないため、車両を運転しながらでも遠隔操作が可能であり、油圧ポンプ等のメンテナンスが不要で、現場搬入後、極めて簡便に直ぐに作業開始が可能であり、油圧を切るための時間も節約できる。 Mainly, in order to rotate the shaft 32a on which the crushing blades 32b are installed in the crushing means 32, to operate the conveyor 41, and if necessary, to operate the electric heater 34 for winter to prevent freezing of the hydrophobic material 11 The machine 51 is essential. In the present invention, all the operation is performed by electric power without using hydraulic pressure, so there is no contamination of soil such as farm fields due to oil leakage, and it is possible to cope with the strict administrative guidance on this point. In addition, because it does not use a hydraulic system, it can be operated remotely while driving a vehicle, maintenance of a hydraulic pump, etc. is unnecessary, and work can be started immediately after delivery to the site. Can save time.
発電機５１の種類、最大電力量等は特に限定はないが、２００Ｖの３相が好ましく、電力は１〜２０ｋＶＡが好ましく、２〜１０ｋＶＡがより好ましく、３〜５ｋＶＡが特に好ましい。最も汎用的な１０ｋＶＡの発電機では、ホッパー３１ａの下部にコンパクトに収まらないが、やや特殊な約４ｋＶＡ程度のものならば、電力量は十分で、かつホッパー３１ａの下部にコンパクトに収納できるので最も好ましい。特殊な約４ｋＶＡ程度の発電機が使用できたために、図１に示したように、本考案の疎水材投入装置を、ちょうど汎用車両１７の荷台に設置できた。 There are no particular limitations on the type of generator 51, the maximum amount of power, etc., but 200V three-phase is preferable, and the power is preferably 1-20 kVA, more preferably 2-10 kVA, and particularly preferably 3-5 kVA. The most general-purpose 10kVA generator does not fit compactly in the lower part of the hopper 31a. However, if it is a slightly special one of about 4kVA, the amount of power is sufficient and it can be stored compactly in the lower part of the hopper 31a. preferable. Since a special generator of about 4 kVA could be used, as shown in FIG. 1, the hydrophobic material charging device of the present invention could be installed just on the loading platform of the general-purpose vehicle 17.
本考案の疎水材投入装置は、圃場等で用いられる汎用の車両に搭載して使用できるようになっている。汎用車両１７の種類は特に限定はないが、例えば好ましいものとして、クローラーダンプ、ホイールダンプ、オフロードダンプ、全輪駆動トラック、小型牽引台車、小型トラック等が挙げられる。 The hydrophobic material charging device of the present invention can be used by being mounted on a general-purpose vehicle used in a field or the like. The type of the general-purpose vehicle 17 is not particularly limited, and preferred examples include a crawler dump, a wheel dump, an off-road dump, an all-wheel drive truck, a small tow truck, a small truck, and the like.
一般に、疎水材投入装置を用いる暗渠工事は、圃場の不使用期間に行われる。具体的には、雪が解ける５月初旬から５月中旬、及び収穫後の９月初旬から１０月下旬である。特に北海道の場合、１１月になると雨が多く、その後は積雪があるので、好適に作業できる期間は、上記期間、すなわち１年に２〜３か月しかない。そのため、従来の専用車両では稼働期間が少な過ぎ、経済的に極めて不利であった。本考案の疎水材投入装置を用いれば、上記期間外（暗渠工事ができない期間）は、別の用途にかかる車両を使えるので、車両の稼働率が上がり無駄がなくなり、コスト的に極めて有利である。 In general, the underdrain work using the hydrophobic material charging device is performed during the non-use period of the field. Specifically, it is from early May to mid-May when the snow melts, and from early September to late October after harvesting. Particularly in Hokkaido, since there is a lot of rain in November and there is snow after that, the period in which work can be suitably performed is only the above period, that is, only 2 to 3 months per year. For this reason, the conventional dedicated vehicle has a very short operating period, which is extremely disadvantageous economically. If the hydrophobic material charging device of the present invention is used, a vehicle for another application can be used outside the above-mentioned period (a period during which the underdrainage work cannot be performed). .
本考案の疎水材投入装置の、（ａ）疎水材収納容器３１、（ｂ）コンベア４１及び（ｃ）発電機５１は全て分離可能とできるため、輸送時には全て輸送トラック車幅内に格納できる。そして作業時は、最適な作業ができるように、任意の距離で引き出す等して使用することができる。 Since all of (a) the hydrophobic material storage container 31, (b) the conveyor 41, and (c) the generator 51 of the hydrophobic material charging device of the present invention can be separated, they can be stored within the width of the transport truck vehicle during transportation. And at the time of work, it can be used by being pulled out at an arbitrary distance so that the optimum work can be performed.
図３と図４に、本考案の疎水材収納容器３１の作業時の形態の一例を示す。疎水材収納容器３１のホッパー３１ａの出口部分上部に、該ホッパー３１ａを横断するように、破砕羽３２ｂが設置されたシャフト３２ａが設けられ、該電機からの電力によって該シャフト３２ａが回転して、疎水材１１を破砕しつつ該コンベア４１の上に疎水材１１を一定量ずつ供給できるようになっている。シャフト３２ａの回転は、回転伝達手段３３によって、モーターの回転が伝搬するようになっている。破砕手段３２は、破砕羽３２ｂが設置されたシャフト３２ａと回転伝達手段３３により成り立っている。本考案で、「破砕」とは、粉砕、ほぐし、詰まりを解く、解砕等をいう。 3 and 4 show an example of the working mode of the hydrophobic material storage container 31 of the present invention. A shaft 32a provided with crushing blades 32b is provided so as to cross the hopper 31a at the upper part of the outlet portion of the hopper 31a of the hydrophobic material storage container 31, and the shaft 32a is rotated by electric power from the electric machine, While the hydrophobic material 11 is crushed, the hydrophobic material 11 can be supplied onto the conveyor 41 by a certain amount. The rotation of the shaft 32a is transmitted by the rotation transmitting means 33. The crushing means 32 includes a shaft 32a on which crushing blades 32b are installed and a rotation transmission means 33. In the present invention, “crushing” means crushing, loosening, clogging, crushing, and the like.
破砕羽３２ｂはシャフト３２ａに直角に設置されているものでもよく、螺旋状に回転できるようになっているものでもよいが、疎水材１１の種類に関係なく用いることができる点等から、シャフト３２ａに直角に設置されているものが好ましい。 The crushing blade 32b may be installed at a right angle to the shaft 32a or may be able to rotate in a spiral shape. However, the shaft 32a can be used regardless of the type of the hydrophobic material 11. It is preferable that it is installed at a right angle to.
破砕羽３２ｂの個数は特に限定はないが、２個〜６個が、破砕の効率の点で好ましく、３個〜４個が特に好ましい。破砕羽３２ｂの形状も特に限定はなく、木製チップ等の場合は破砕羽３２ｂへの巻き付きがなく、貝殻等の場合は破砕羽３２ｂの破損がないように決定される。図６に示したような棒状の直方体が、上記の性能に優れ、あらゆる疎水材１１に好適に適用できるために特に好ましい。 The number of crushing feathers 32b is not particularly limited, but 2 to 6 is preferable in terms of crushing efficiency, and 3 to 4 is particularly preferable. The shape of the crushing wing 32b is not particularly limited, and is determined so that the crushing wing 32b is not wound in the case of a wooden chip or the like, and the crushing wing 32b is not damaged in the case of a shell or the like. A rod-shaped rectangular parallelepiped as shown in FIG. 6 is particularly preferable because it is excellent in the above performance and can be suitably applied to any hydrophobic material 11.
破砕羽３２ｂの材質は特に限定はないが、貝殻等の硬いものの粉砕のためには硬度が高い金属等が好ましい。また、使用して摩耗した場合に簡単に交換できることがメンテナンスを考慮すると好ましい。 The material of the crushing feather 32b is not particularly limited, but a metal having high hardness is preferable for crushing hard materials such as shells. Moreover, it is preferable that maintenance can be taken into consideration when it is worn and worn.
シャフト３２ａの回転数は特に限定はないが、効率的な破砕のために、０．２〜１回／分が好ましく、０．４〜０．８回／分がより好ましく、０．５〜０．７回／分が特に好ましい。 The number of rotations of the shaft 32a is not particularly limited, but is preferably 0.2 to 1 time / minute, more preferably 0.4 to 0.8 time / minute, and 0.5 to 0 for efficient crushing. .7 times / minute is particularly preferred.
破砕手段３２の位置、すなわちシャフト３２ａの位置は、疎水材収納容器３１のホッパー３１ａの出口部分上部であればよいが、ホッパー３１ａ全体の高さの、下から１／１０〜１／３の位置が好ましく、１／６〜１／３．２の位置がより好ましく、１／４〜１／３．５の位置が特に好ましい。 The position of the crushing means 32, that is, the position of the shaft 32a may be at the upper part of the outlet portion of the hopper 31a of the hydrophobic material storage container 31, but the height of the entire hopper 31a is 1/10 to 1/3 from the bottom. The position of 1/6 to 1 / 3.2 is more preferable, and the position of 1/4 to 1 / 3.5 is particularly preferable.
破砕手段３２によって、もみがら、木材チップ、セラミックチップ等、水を含むと凝集して出て来なくなったり、一気に大量に落下したりする疎水材１１を、解砕しながら一定量ずつコンスタントにコンベア４１上に供給できる。また、ホタテ貝殻、カキ貝殻等、粉砕が必要な疎水材１１でも、粉砕しながら一定量ずつコンスタントにコンベア４１上に供給できる。更に、粉石、ビリ砂利、石灰石、火山礫等、詰まり易い疎水材１１も、詰まりを解きつつ一定量ずつコンスタントにコンベア４１上に供給できる。また、バーク等の粘り気がありホッパー３１ａから出てきたところで山のようにたまってしまいがちな疎水材１１でも、少量ずつコンスタントにコンベア４１上に供給できる。特に、ホタテ貝殻は直径が２０ｃｍ程もあるため、本考案における破砕手段３２によって、疎水材１１としての適当な大きさに粉砕しつつ掘削溝１２に投入が可能となった。 The crushing means 32 constantly conveys the hydrophobic material 11 such as rice husks, wood chips, ceramic chips, etc. that are aggregated and will not come out when they contain water or fall in large quantities at a time while being crushed. 41 can be supplied. Further, even a hydrophobic material 11 that needs to be crushed, such as scallop shells, oyster shells, etc., can be constantly supplied onto the conveyor 41 while being crushed. Furthermore, the hydrophobic material 11 that is easily clogged, such as powdered stone, billi gravel, limestone, and volcanic gravel, can be constantly supplied onto the conveyor 41 by a certain amount while releasing the clogging. Further, even the hydrophobic material 11 that is sticky and tends to accumulate like a mountain when it comes out of the hopper 31a can be supplied to the conveyor 41 in small amounts. In particular, since the scallop shell has a diameter of about 20 cm, the crushing means 32 according to the present invention enables the scallop shell to be put into the excavation groove 12 while being crushed to an appropriate size as the hydrophobic material 11.
図６に、破砕手段３２をホッパー３１ａの上から見た一形態を示す。図６では、４個の破砕羽３２ｂがシャフト３２ａに破砕羽固定用ボルト３２ｃで固定されている。疎水材１１を破砕する際に、例えば疎水材１１が破砕されずに、シャフト３２ａ等に無理な力が入った時に、破砕手段３２全体が破損する前に、破砕羽３２ｂが、それが設置されているシャフト３２ａから外れるようになっていることが好ましい。破砕羽３２ｂがシャフト３２ａから外れることによって、シャフト３２ａが折れる等、破砕手段３２全体が破損することを防ぐことができる。図６に示したように、破砕羽３２ｂをシャフト３２ａに破砕羽固定用ボルト３２ｃで固定しておくことが好ましい。 FIG. 6 shows an embodiment in which the crushing means 32 is viewed from above the hopper 31a. In FIG. 6, four crushing blades 32b are fixed to the shaft 32a with crushing blade fixing bolts 32c. When the hydrophobic material 11 is crushed, for example, when the hydrophobic material 11 is not crushed and an excessive force is applied to the shaft 32a or the like, the crushing blade 32b is installed before the entire crushing means 32 is damaged. It is preferable to be detached from the shaft 32a. By detaching the crushing blade 32b from the shaft 32a, it is possible to prevent the entire crushing means 32 from being damaged, such as the shaft 32a being broken. As shown in FIG. 6, it is preferable to fix the crushing blade 32b to the shaft 32a with a crushing blade fixing bolt 32c.
図３に示すように、ホッパー３１ａの下には、必須ではないがホッパー筒口３７が設けられていることが好ましい。また、疎水材収納容器３１のホッパー３１ａ部分は、要すれば筋交いの入った架台で固定されていることが好ましい。 As shown in FIG. 3, a hopper cylinder port 37 is preferably provided below the hopper 31a, although it is not essential. Moreover, it is preferable that the hopper 31a portion of the hydrophobic material storage container 31 is fixed by a pedestal containing braces if necessary.
図５に、疎水材投入装置の疎水材収納容器３１を運搬時の形態を示す。ホッパー上縁の垂直板３１ｂが蝶番３１ｃによって外側に倒れ畳まれてコンパクトになっている。運搬時の疎水材収納容器３１の高さは、通常１〜３ｍ、好ましくは１．５〜２ｍとできるので、運搬が容易である。また、垂直板３１ｂを使用すれば、十分な量の疎水材１１を疎水材収納容器３１に収納できる。 In FIG. 5, the form at the time of carrying the hydrophobic material storage container 31 of a hydrophobic material injection | throwing-in apparatus is shown. A vertical plate 31b at the upper edge of the hopper is folded outward by a hinge 31c to be compact. Since the height of the hydrophobic material storage container 31 at the time of conveyance can be normally set to 1 to 3 m, preferably 1.5 to 2 m, the conveyance is easy. If the vertical plate 31 b is used, a sufficient amount of the hydrophobic material 11 can be stored in the hydrophobic material storage container 31.
疎水材収納容器３１のホッパー３１ａは、略逆四角錐の形状をしており、該ホッパー３１ａの内側の稜線部分に隅肉（すみにく、ｆｉｌｌｅｔ）３６が設けられていることが好ましい。隅肉３６がないと、かぎ型に曲がった部分の内側の股の部分に、疎水材１１が溜まってホッパー３１ａの下に位置する破砕手段３２までに落ちて来なくなる場合がある。 It is preferable that the hopper 31a of the hydrophobic material storage container 31 has a substantially inverted quadrangular pyramid shape, and a fillet 36 is provided on the inner ridge line portion of the hopper 31a. If the fillet 36 is not present, the hydrophobic material 11 may accumulate in the crotch portion inside the hook-shaped portion and may not fall to the crushing means 32 positioned below the hopper 31a.
疎水材収納容器３１のホッパー３１ａの内側は、疎水材１１との間の摩擦係数を低下させる物質によりコーティングされていることが、疎水材１１の破砕手段３２までのスムースな落下のために好ましい。摩擦係数を低下させる物質は特に限定はないが、ＤＬＣ（Ｄｉａｍｏｎｄ Ｌｉｋｅ Ｃａｒｂｏｎ）が好ましい。ＤＬＣとは、水素を若干含有した非晶質構造で、ダイヤモンド結合やグラファイト結合を有するものであり、プラズマを使用した気相合成法で合成されるカーボン薄膜である。ＤＬＣのコーティングをスリックコートということもある。 The inside of the hopper 31a of the hydrophobic material container 31 is preferably coated with a substance that reduces the coefficient of friction with the hydrophobic material 11 in order to smoothly drop the hydrophobic material 11 to the crushing means 32. The substance for reducing the friction coefficient is not particularly limited, but DLC (Diamond Like Carbon) is preferable. DLC is an amorphous structure containing a little hydrogen, has diamond bonds and graphite bonds, and is a carbon thin film synthesized by a gas phase synthesis method using plasma. The DLC coating is sometimes referred to as a slick coat.
本考案の疎水材投入装置は、図７に示したように、疎水材収納容器３１のホッパー３１ａ部分の外側に、疎水材収納容器３１に収納されている疎水材１１が凍結することを防止するための冬季用電熱ヒーター３４が設置されていることも好ましい。従来の方法では、ダンプカーの荷台にヒーターを設置することは不可能である。本考案の疎水材投入装置の疎水材収納容器３１は単純な外壁を有しているため、ヒーターの設置が可能になった。そして、これにより寒冷地の低温の日での使用が可能になった。冬季用電熱ヒーター３４による加熱温度は、疎水材１１が固まらない温度であれば特に限定はないが、疎水材収納容器３１内の温度で、２℃〜１２０℃が好ましく、１０℃〜８０℃がより好ましく、特に好ましくは１５℃〜４０℃である。 As shown in FIG. 7, the hydrophobic material charging device of the present invention prevents the hydrophobic material 11 stored in the hydrophobic material storage container 31 from freezing outside the hopper 31a portion of the hydrophobic material storage container 31. It is also preferable that a winter electric heater 34 is installed. In the conventional method, it is impossible to install a heater on the dump truck bed. Since the hydrophobic material storage container 31 of the hydrophobic material charging device of the present invention has a simple outer wall, a heater can be installed. As a result, it can be used on cold days in cold regions. The heating temperature by the electric heater 34 for winter is not particularly limited as long as the hydrophobic material 11 does not solidify. However, the temperature in the hydrophobic material container 31 is preferably 2 ° C to 120 ° C, and preferably 10 ° C to 80 ° C. More preferably, it is 15 to 40 degreeC.
本考案の疎水材投入装置は、上記疎水材収納容器３１のホッパー３１ａ部分の下部に排出量調節用手動装置３５を設けて、上記コンベア４１の上に疎水材１１を所定量ずつ供給できるようにすることも好ましい。図７では、ホッパー３１ａ下部の右側に排出量調節用手動装置３５があり、上下移動して疎水材１１の出口面積を調節できるようになっている。 The hydrophobic material charging device of the present invention is provided with a manual device 35 for adjusting the discharge amount at the lower part of the hopper 31a portion of the hydrophobic material storage container 31 so that the hydrophobic material 11 can be supplied onto the conveyor 41 by a predetermined amount. It is also preferable to do. In FIG. 7, there is a manual device 35 for adjusting the discharge amount on the right side below the hopper 31a, which can move up and down to adjust the exit area of the hydrophobic material 11.
従来のダンプカーの荷台からコンベア４１上に疎水材１１を落下させる方式では、落ちない状態を避けることが精いっぱいで、コンベア４１上への疎水材１１の供給量をコントロールすること等は到底出来なかった。本考案によれば、ホッパー３１ａの出口部分上部に設けられ破砕手段３２があることによって疎水材１１が破砕されるので、その下の排出量調節用手動装置３５によって、疎水材１１を所定量ずつ落下させることが可能となる。 In the conventional method in which the hydrophobic material 11 is dropped onto the conveyor 41 from the loading platform of the dump truck, it is extremely difficult to avoid the state in which the hydrophobic material 11 does not fall, and the supply amount of the hydrophobic material 11 onto the conveyor 41 cannot be controlled. . According to the present invention, since the hydrophobic material 11 is crushed by the crushing means 32 provided at the upper part of the outlet portion of the hopper 31a, the hydrophobic material 11 is removed by a predetermined amount by the discharge amount adjusting manual device 35 below. It can be dropped.
図８は、本考案の疎水材投入装置における疎水材収納容器３１とコンベア４１の配置等を示す概略斜視図である。コンベア４１は図８でいうと左右に移動可能になっていて、掘削溝１２の真上にコンベア４１の末端又は疎水材導入部材４２が来るように調整可能である。詳しくは、本考案の疎水材投入装置を輸送トラック等に載せて輸送中は、コンベア４１を、図８でいうと左側に移動させてトラック等の内に収納しておき、疎水材１１を投入するときは（本考案の疎水材投入装置を使用するときは）、コンベア４１を図８でいうと右側に移動させ、疎水材投入装置や「疎水材投入装置を圃場等で載せている汎用車両１７」から直角方向に張り出させて使用することができる。 FIG. 8 is a schematic perspective view showing the arrangement of the hydrophobic material storage container 31 and the conveyor 41 in the hydrophobic material charging apparatus of the present invention. The conveyor 41 is movable to the left and right in FIG. 8, and can be adjusted so that the end of the conveyor 41 or the hydrophobic material introducing member 42 comes directly above the excavation groove 12. Specifically, during the transportation with the hydrophobic material feeding device of the present invention mounted on a transportation truck or the like, the conveyor 41 is moved to the left in FIG. 8 to be stored in the truck and the hydrophobic material 11 is loaded. When (when using the hydrophobic material charging device of the present invention), the conveyor 41 is moved to the right in FIG. 8, and the hydrophobic material charging device or the “general-purpose vehicle on which the hydrophobic material charging device is mounted on a farm field or the like” It can be used by projecting in a direction perpendicular to 17 ”.
使用時にコンベア４１を図８では右側に移動させる距離、すなわち汎用車両１７から直角方向に張り出させる距離は特に限定はないが、４０〜８０ｃｍが好ましく、５０〜７０ｃｍが特に好ましい。これより短いと、汎用車両１７と掘削溝１２との距離が近過ぎて、汎用車両１７が移動中に掘削溝１２に落ちる可能性があり安全性に欠ける場合があり、長過ぎると、輸送トラック等での輸送時にホッパー３１ａの下部等に収納し難い場合がある。 The distance by which the conveyor 41 is moved to the right in FIG. 8 during use, that is, the distance over which the conveyor 41 protrudes from the general-purpose vehicle 17 is not particularly limited, but is preferably 40 to 80 cm, particularly preferably 50 to 70 cm. If the length is shorter than this, the distance between the general-purpose vehicle 17 and the excavation groove 12 may be too short, and the general-purpose vehicle 17 may fall into the excavation groove 12 during movement. In some cases, it may be difficult to store in the lower part of the hopper 31a during transportation.
本考案の疎水材投入装置が使用できる場所は、田圃、畑等の圃場；牧草地；ゴルフ場；住宅地、別荘地等の宅地；等が挙げられる。これらの場所を「圃場等」と略記する場合がある。 Examples of the place where the hydrophobic material charging device of the present invention can be used include fields such as rice fields and fields; pastures; golf courses; residential areas such as residential areas and villa areas; These locations may be abbreviated as “farm fields”.
以下に、実施例及び比較例を挙げて本考案を更に具体的に説明するが、本考案は、その要旨を超えない限りこれらの実施例に限定されるものではない。 Hereinafter, the present invention will be described more specifically with reference to examples and comparative examples. However, the present invention is not limited to these examples as long as the gist thereof is not exceeded.
実施例１
図１、図３〜５に示す本考案の疎水材投入装置Ａ（作業時高さ：２１００ｍｍ、作業時幅３０５０ｍｍ×２０００ｍｍ、容量：３．７ｍ３、重量：９００ｋｇ）を作製した。疎水材投入装置におけるベルトコンベヤ部は図８に示すものを用いた（ベルト：３５０Ｗ×１２５Ｋ×１．５×４２５ＥＤ平ベルト、ベルト速度：約４８ｍ／分、全長：２３００ｍｍ、動力：１．０ｋｗ（２００Ｖ））。また、発電機として３相２００Ｖ、４ｋＶＡの発電機（ＥＴ４５００Ｋ１、ＨＯＮＤＡ社製）を用いた。
Example 1
A hydrophobic material feeding device A (working height: 2100 mm, working width 3050 mm × 2000 mm, capacity: 3.7 m 3 , weight: 900 kg) shown in FIG. 1 and FIGS. The belt conveyor unit in the hydrophobic material charging apparatus shown in FIG. 8 was used (belt: 350 W × 125 K × 1.5 × 425 ED flat belt, belt speed: about 48 m / min, total length: 2300 mm, power: 1.0 kW ( 200V)). In addition, a three-phase 200 V, 4 kVA generator (ET4500K1, manufactured by HONDA) was used as a generator.
上記の疎水材投入装置Ａを車両クローラーダンプの荷台に設置し、疎水材として、木製チップを４．０ｍ３、垂直板を立てて容積を大きくした疎水材収納容器内に収納した。北海道の後志支庁管内の蘭越地区圃場にて、秘密を保持する義務のある特定人（具体的には、作業者、装置開発者等の関係者）しかいないところで、暗渠排水工事の疎水材投入作業を行った。 The above-mentioned hydrophobic material feeding device A was installed on a loading platform of a vehicle crawler dumper, and was stored as a hydrophobic material in a hydrophobic material storage container having a wooden chip of 4.0 m 3 and a vertical plate raised in volume. In the Rankoshi area farm in the jurisdiction of the Goshi branch office in Hokkaido, where there is only a specific person (specifically, a person concerned, such as an operator or equipment developer) who is obliged to keep the secret, the hydrophobic material input work for underdrainage construction Went.
その結果、疎水材である木製チップが疎水材収納容器内に詰まることなく、更に、均一にベルトコンベア上に供給され、次いで掘削溝に投入された。また、作業員一人のみで車両及び疎水材投入装置を操作することができ、車両が掘削溝に落ちる心配もせず、安全に疎水材投入作業が完了した。 As a result, the wooden chips, which are hydrophobic materials, were further uniformly fed onto the belt conveyor without being clogged in the hydrophobic material storage container, and then put into the excavation groove. Also, only one worker could operate the vehicle and the hydrophobic material charging device, and the hydrophobic material charging operation was completed safely without worrying that the vehicle would fall into the excavation groove.
実施例２
実施例１記載の疎水材投入装置Ａを用いて、疎水材として、実施例１の木製チップを４．０ｍ３用いる代わりに、ホタテ貝殻を４．０ｍ３使用したが、実施例１と同様に問題なく疎水材投入作業が完了した。
Example 2
With hydrophobic material feeding device A of Example 1, as a hydrophobic material, the wood chips of Example 1 in place using 4.0 m 3, the scallop shell 4.0 m 3 was used, in the same manner as in Example 1 The hydrophobic material charging operation was completed without any problems.
実施例３
実施例１記載の疎水材投入装置Ａを用いて、疎水材として、実施例１の木製チップを４．０ｍ３用いる代わりに、切込砕石（平均径０ｍｍ〜４０ｍｍ）を４．０ｍ３使用したが、実施例１と同様に問題なく疎水材投入作業が完了した。
Example 3
With hydrophobic material feeding device A of Example 1, as a hydrophobic material, the wood chips of Example 1 in place using 4.0 m 3, the cutting crushed stone (average diameter 0Mm～40mm) was 4.0 m 3 using However, the hydrophobic material charging operation was completed without any problem as in Example 1.
比較例１
実施例１に記載の疎水材投入装置において、ホッパーに破砕手段のない疎水材投入装置ａを用いた以外は実施例１と同様にして疎水材投入作業を行ったところ、疎水材である木製チップが疎水材収納容器内で固まり、疎水材排出口で詰まってしまった。
Comparative Example 1
In the hydrophobic material charging device described in Example 1, the hydrophobic material charging operation was performed in the same manner as in Example 1 except that the hydrophobic material charging device a having no crushing means in the hopper was used. Was hardened in the hydrophobic material container and clogged at the hydrophobic material outlet.
比較例２
実施例１〜３において、疎水材投入装置Ａの代わりにダンプカーの荷台の傾斜によって、疎水材をコンベア上に供給したところ、ダンプカーの荷台に収容した疎水材が固まってしまったり、ダンプカーの荷台の傾斜を利用して疎水材を投入するため、均一に疎水材を掘削溝に投入することができなかったりして、人手による作業の手間が大幅にかかった。また、ホタテ貝殻の場合は直径が約２０ｃｍもあるため、破砕手段がないので疎水材として好適には使用できなかった。また、疎水材の種類によって、専用のコンベアや、最悪の場合、それぞれの専用車両が必要であり、コスト的にも問題であった。
Comparative Example 2
In Examples 1 to 3, when the hydrophobic material is supplied onto the conveyor by the inclination of the dump truck bed instead of the hydrophobic material feeding device A, the hydrophobic material contained in the dump truck bed is solidified, or the dump truck bed Since the hydrophobic material is introduced by using the slope, it is not possible to uniformly introduce the hydrophobic material into the excavation groove, which requires a lot of labor. In the case of a scallop shell, the diameter is about 20 cm, and therefore, there is no crushing means, so that it could not be suitably used as a hydrophobic material. Further, depending on the type of the hydrophobic material, a dedicated conveyor or, in the worst case, each dedicated vehicle is necessary, which is a problem in terms of cost.
本考案の疎水材投入装置は、貝殻、石灰石、砂利、木のチップ等のあらゆる疎水材を掘削溝に安全、均一に投入することができ、汎用車両に容易に脱着が可能であるため、暗渠排水工事に広く利用されるものである。 The hydrophobic material injection device of the present invention can safely and uniformly input any hydrophobic material such as shells, limestone, gravel, wood chips, etc. into the excavation groove and can be easily detached from general purpose vehicles. It is widely used for drainage work.
