Description

本発明は、暗渠管敷設装置に関し、詳しくは、圃場に形成した溝の底部に暗渠管を敷設するとともに、暗渠管上部の溝内に疎水材を投入する暗渠管敷設装置に関する。   The present invention relates to an underdrain pipe laying apparatus, and more particularly, to an underdrain pipe laying apparatus for laying an underdrain pipe at the bottom of a groove formed in a field and injecting a hydrophobic material into the groove at the top of the underdrain pipe.

圃場の地中に、排水用暗渠となる溝を形成するとともに、形成した溝内に籾殻や木材チップなどの疎水材を充填する排水用暗渠形成装置が知られている（例えば、特許文献１参照。）。また、形成した溝の底部に暗渠管を敷設するとともに、該暗渠管の上部に疎水材を積層充填する暗渠排水敷設装置も知られている（例えば、特許文献２参照。）。   There is known a drainage culvert forming apparatus for forming a groove serving as drainage culvert in the ground of a field and filling a hydrophobic material such as rice husk or wood chip into the formed groove (for example, see Patent Document 1) ). There is also known an underdrain drainage laying apparatus in which an underdrain pipe is laid on the bottom of the formed groove, and a hydrophobic material is laminated and filled on the top of the underdrain pipe (see, for example, Patent Document 2).

特開２００４−２４４８０３号公報Unexamined-Japanese-Patent No. 2004-244803 特開２００４−３２６８号公報JP 2004-3268 A

特許文献１，２に記載された装置では、作業効率を向上させるため、疎水材を投入するためのホッパーの容量を大きくすることにより、１回の疎水材投入での作業距離を長くするようにしていた。しかし、容量の大きなホッパーに疎水材を投入する際には、装置を長時間停止させる必要があることから、作業効率の向上には限界があった。一方、容積を大きくするために背が高くなったホッパー内に大量の疎水材を投入するためには、疎水材を収納した袋を吊り上げるためのクレーンを必要とするという問題がある。さらに、大きなホッパー内に大量の疎水材を投入すると、疎水材自体の重量でホッパー下部の疎水材が圧密され、ブリッジが発生して疎水材が詰まることがあり、圧密された疎水材をほぐすための撹拌機などをホッパー内に設ける必要も生じていた。   In the devices described in Patent Literatures 1 and 2, in order to improve the working efficiency, the working distance in one hydrophobic material charging is increased by increasing the capacity of the hopper for charging the hydrophobic material. It was However, since it is necessary to stop the device for a long time when adding the hydrophobic material to the hopper having a large capacity, there is a limit to the improvement of the working efficiency. On the other hand, there is a problem that a crane is required to lift the bag containing the hydrophobic material in order to load a large amount of the hydrophobic material into the tall hopper in order to increase the volume. Furthermore, if a large amount of hydrophobic material is placed in a large hopper, the weight of the hydrophobic material itself consolidates the hydrophobic material at the bottom of the hopper, causing bridges to clog the hydrophobic material and loosening the consolidated hydrophobic material. It was also necessary to provide a stirrer of the above in the hopper.

そこで本発明は、溝形成部で形成した溝内への暗渠管の敷設及び疎水材の充填を確実かつ効率よく行うことができる暗渠管敷設装置を提供することを目的としている。   Then, an object of this invention is to provide the underdrain pipe laying apparatus which can perform laying of an underdrain pipe and filling of a hydrophobic material in the groove | channel formed by the groove formation part reliably and efficiently.

上記目的を達成するため、本発明の暗渠管敷設装置は、走行体に牽引されながら地中に溝を形成する溝形成部と、該溝形成部の後方で該溝形成部で形成した溝の底部に向けて長尺で可撓性を有する暗渠管をガイドする暗渠管ガイド部と、該暗渠管ガイド部の後方で前記溝内に挿入され、前記溝の底部に敷設された暗渠管の上方の溝内に疎水材を充填する疎水材充填部と、該疎水材充填部の上方から疎水材充填部内に前記疎水材を落下させるホッパーと、該ホッパーの上端に開口した矩形状の開口部の周囲に設けられた水平方向の作業デッキ部と、前記開口部の３辺から上方に向かってそれぞれ突設した疎水材ガイド板と、前記暗渠管ガイド部のガイド端から溝の底部に送出される暗渠管を溝の底面に向けて押圧する暗渠管押圧部材と、前記疎水材充填部の後端上部に設けられて溝内に充填される疎水材の充填高さを設定する疎水材高さ設定部材と、前記作業デッキ部の一側で前記暗渠管を巻回したホースリールを回転可能に保持するリール保持部とを備えていることを特徴としている。   In order to achieve the above object, the underdrain pipe laying device of the present invention comprises a groove forming portion which forms a groove in the ground while being pulled by a traveling body, and a groove formed by the groove forming portion behind the groove forming portion. An elongate tube guide portion for guiding a long and flexible underdrain tube toward the bottom, and above the underdrain tube installed at the bottom of the groove and inserted in the groove behind the underdrain tube guide. A hydrophobic material-filled portion for filling a hydrophobic material in the groove, a hopper for dropping the hydrophobic material into the hydrophobic material-filled portion from above the hydrophobic material-filled portion, and a rectangular opening opened at the upper end of the hopper It is sent out to the bottom of the groove from the guide end of the horizontal work deck part provided around the periphery, the hydrophobic material guide plate protruding from the three sides of the opening upward from the three sides of the opening and the guide part of the underdrain tube. An under-tube pressing member for pressing the under-tube against the bottom of the groove; A hydrophobic material height setting member provided on the upper end of the rear end of the material filling section to set the filling height of the hydrophobic material to be filled in the groove, and a hose wound around the underdrain pipe on one side of the working deck section And a reel holding portion for rotatably holding the reel.

さらに、本発明の暗渠管敷設装置は、前記ホッパーの側壁がホッパーの内方に向かって凸となる曲面で形成されていること、前記暗渠管押圧部材が高さ位置調整可能に設けられていること、前記疎水材高さ設定部材が高さ位置調整可能に設けられていること、また、前記ホッパーの開口部上端縁と前記作業デッキ部の上面とが面一であることを特徴としている。   Furthermore, in the underdrain pipe laying device according to the present invention, the side wall of the hopper is formed by a curved surface that is convex toward the inside of the hopper, and the underdrain pipe pressing member is provided so that height position adjustment is possible. It is characterized in that the hydrophobic material height setting member is provided so as to be adjustable in height position, and the upper end edge of the opening of the hopper is flush with the upper surface of the working deck portion.

本発明の暗渠管敷設装置によれば、地中に溝を形成しながら暗渠管の敷設と疎水材の充填とを同時に行うことができる。特に、ホッパーの上端開口部の周囲に作業デッキ部を設けるとともに、開口部の３辺に疎水材ガイド板を突設したので、疎水材ガイド板が設けられていない方向の作業デッキ部に立った作業者が、疎水材が入った袋を高く持ち上げることなく、ホッパー内への疎水材の投入を容易に行うことができる。さらに、暗渠管押圧部材によって暗渠管を溝底部に確実に敷設することができ、疎水材高さ設定部材によって疎水材の投入高さを一定にすることができる。また、ホッパーの側壁を内方に向かって凸となる曲面で形成することにより、疎水材を円滑に落下させることができる。特に、ホッパーの開口上端縁と作業デッキ部の上面とを面一にすることにより、疎水材が入った袋の上部を開口し、この開口をホッパーの開口部に向けて袋を倒した後、袋の底部を持ち上げるだけでホッパー内に疎水材を投入できるの、疎水材投入作業の負担を大幅に軽減することができる。このとき袋内の疎水材の量を、一般的な１０〜２０ｋｇ程度にすることにより、作業デッキ部に袋を持ち上げる作業を、クレーンなどの機器を必要とせずに人力によって容易に行うことができる。   According to the underdrain pipe laying device of the present invention, it is possible to simultaneously perform the underdrain pipe laying and the hydrophobic material filling while forming the ditch in the ground. In particular, the work deck portion is provided around the upper end opening of the hopper, and the hydrophobic material guide plate is protruded on three sides of the opening, so the device stands on the work deck portion in the direction where the hydrophobic material guide plate is not provided. The operator can easily load the hydrophobic material into the hopper without raising the bag containing the hydrophobic material. Furthermore, the underdrain pipe can be reliably laid on the groove bottom by the underdrain pipe pressing member, and the input height of the hydrophobic material can be made constant by the hydrophobic material height setting member. In addition, the hydrophobic material can be smoothly dropped by forming the side wall of the hopper with a curved surface that is convex toward the inside. In particular, by making the opening upper edge of the hopper flush with the upper surface of the working deck, the upper portion of the bag containing the hydrophobic material is opened, and this opening is directed to the opening of the hopper, and Since the hydrophobic material can be introduced into the hopper simply by lifting the bottom of the bag, the burden of the hydrophobic material introduction operation can be greatly reduced. At this time, by setting the amount of hydrophobic material in the bag to about 10 to 20 kg in general, the work of lifting the bag to the working deck portion can be easily performed manually without the need of a device such as a crane. .

Further, insertion of the underdrain pipe 14 into the underdrain pipe guide portion 15 and connection of the rear end and the front end of the underdrain pipe 14 to the right forward part in the working direction with respect to the opening 18a of the hopper 18 are performed. The auxiliary deck 19a is provided.

疎水材ガイド板２０は、ホッパー１８の開口部１８ａに対して作業時進行方向の前部側、後部側及び右側に、上部開口の三方を囲む状態で設けられており、作業デッキ部１９が設けられた左側には設けられていない。疎水材ガイド板２０の高さは、ホッパー１８内に疎水材１６を投入する際に、疎水材１６が周囲に飛散しない程度に設定されており、作業デッキ部１９上から疎水材１６を投入する方向に対向する作業時進行方向右側の疎水材ガイド板２０を他より高く形成することが好ましい。また、作業時進行方向の後部側の疎水材ガイド板２０を、作業デッキ部１９側に突出させておくことにより、作業時の後方への安全性も向上する。   The hydrophobic guide plate 20 is provided on the front side, the rear side and the right side in the working direction with respect to the opening 18a of the hopper 18 so as to surround three sides of the upper opening, and the working deck portion 19 is provided. It is not provided on the left side. The height of the hydrophobic material guide plate 20 is set to such an extent that the hydrophobic material 16 does not scatter around when the hydrophobic material 16 is loaded into the hopper 18, and the hydrophobic material 16 is loaded from the work deck portion 19. It is preferable to form the hydrophobic material guide plate 20 on the right side in the traveling direction opposite to the direction higher than the other. Further, by causing the hydrophobic material guide plate 20 on the rear side in the traveling direction in operation to project toward the operation deck portion 19 side, the safety to the rear in operation is also improved.

また、本形態例に示す暗渠管敷設装置では、ホッパー１８の内部に疎水材１６をほぐすための疎水材撹拌部材３１を設けている。この疎水材撹拌部材３１は、両端部をホッパー１８の前後壁に回転可能に支持された回転軸３１ａの周囲に複数の撹拌羽根３１ｂを突設させたもので、回転軸３１ａの一端に連結した電気モータや油圧モータなどの駆動手段３１ｃで回転軸３１ａを回転させて撹拌羽根３１ｂで疎水材１６を撹拌することにより、疎水材１６にブリッジが発生することをより確実に防止している。   Moreover, in the underdrain pipe laying apparatus shown in this embodiment, the hydrophobic material stirring member 31 for loosening the hydrophobic material 16 is provided inside the hopper 18. The hydrophobic material stirring member 31 has a plurality of stirring blades 31b protruding around the rotation shaft 31a rotatably supported at the front and rear walls of the hopper 18 at both ends, and is connected to one end of the rotation shaft 31a The rotation of the rotary shaft 31a by the driving means 31c such as an electric motor or a hydraulic motor and the agitation of the hydrophobic material 16 by the agitating blades 31b prevents the occurrence of the bridge in the hydrophobic material 16 more reliably.

このように形成された暗渠管敷設装置１０は、自走可能な走行体であるブルドーザ５１の後部に設けられた平行リンク部材５１ａに前記走行体連結部２５を連結した状態で暗渠管敷設作業を行う。暗渠管敷設作業における溝１２の底面位置は、レーザ受光器２６で受光した基準レーザ光によって平行リンク部材５１ａに設けたシリンダ５１ｂを伸縮させることにより、一定の水勾配が得られるように高さが調節される。   The thus-formed underdrain pipe laying apparatus 10 performs underdrain pipe laying work in a state where the traveling body connecting portion 25 is connected to the parallel link member 51a provided at the rear of the bulldozer 51 which is a self-propelled traveling body. Do. The bottom position of the groove 12 in the underdrain pipe laying operation has a height such that a constant water gradient can be obtained by expanding and contracting the cylinder 51b provided on the parallel link member 51a by the reference laser beam received by the laser receiver 26. It is adjusted.

また、暗渠管敷設作業を行う前に、暗渠管敷設位置に沿って疎水材入り袋を所定間隔で配置しておく。この疎水材入り袋の配置作業は、トラックなどの適宜な走行体の荷台に載置した疎水材入り袋を、溝内への疎水材１６の投入量に応じた間隔で地面上に落としていけばよい。   Also, before performing the underdrain pipe laying operation, the hydrophobic material-containing bags are arranged at predetermined intervals along the underdrain pipe laying position. In the placement of the hydrophobic material-containing bag, the hydrophobic material-containing bag placed on a suitable carrier such as a truck may be dropped on the ground at an interval corresponding to the amount of the hydrophobic material 16 introduced into the groove. Just do it.

暗渠管敷設作業は、ブルドーザ５１を所定の速度、例えば歩行速度程度で移動させて行う。このとき、作業者の一人は、暗渠管敷設装置１０の移動に伴って歩きながら、地面上に配置された疎水材入り袋を作業デッキ部１９の上面に載置していく。別の作業者は、作業デッキ部１９の上に乗った状態で、作業デッキ部１９の上面に載置された疎水材入り袋の袋の一端を切断するなどして開封し、開封した部分がホッパー１８の開口部１８ａ内に入るようにして袋を倒した後、袋の他端を持ち上げて袋内の疎水材１６をホッパー１８内に投入していく。このとき、作業デッキ部１９の上面と開口部の上縁とを面一にしているので、作業デッキ部１９の上に疎水材が落下しても、ホッパー１８内に容易に投入することができる。   The underdrain pipe laying operation is performed by moving the bulldozer 51 at a predetermined speed, for example, a walking speed. At this time, one of the workers places the hydrophobic material-containing bag disposed on the ground on the upper surface of the work deck portion 19 while walking along with the movement of the underdrain pipe laying device 10. Another worker opens the working deck portion 19 by cutting one end of the hydrophobic material-containing bag placed on the upper surface of the working deck portion 19 and opens the opened portion. After the bag is turned down so as to enter the opening 18a of the hopper 18, the other end of the bag is lifted to load the hydrophobic material 16 in the bag into the hopper 18. At this time, since the upper surface of the working deck 19 and the upper edge of the opening are flush with each other, even if the hydrophobic material falls on the working deck 19, it can be easily thrown into the hopper 18. .

暗渠管敷設装置１０の移動に伴って溝形成部１３によって所定深さの溝１２が形成され、暗渠管ガイド部１５でガイドされた暗渠管１４が溝１２の底部に連続的に送出される。このとき、押圧位置調節部材２７によって所定位置に調節された押圧ローラ２１ａが暗渠管１４を溝１２の底面に押圧していくので、暗渠管１４を溝１２の底面に沿って確実に敷設していくことができる。   With the movement of the underdrain pipe laying device 10, the groove forming part 13 forms a groove 12 of a predetermined depth, and the underdrain pipe 14 guided by the underdrain pipe guide 15 is continuously delivered to the bottom of the groove 12. At this time, since the pressure roller 21a adjusted to a predetermined position by the pressure position adjusting member 27 presses the underdrain tube 14 against the bottom of the groove 12, the underdrain tube 14 is reliably laid along the bottom of the groove 12 Can go.

ホッパー１８内に投入された疎水材１６は、溝底面の暗渠管１４の上方を覆うようにして疎水材充填部１７の下部開口から溝１２内に充填される。また、充填高さ調節部材２８の調節板２２ｂの高さを調節レバー３０によって所定高さに調節しておくことにより、溝１２内における疎水材１６の充填高さを均一にすることができる。   The hydrophobic material 16 introduced into the hopper 18 is filled into the groove 12 from the lower opening of the hydrophobic material filled portion 17 so as to cover the upper part of the underdrain pipe 14 at the bottom of the groove. Further, by adjusting the height of the adjusting plate 22b of the filling height adjusting member 28 to a predetermined height by the adjusting lever 30, the filling height of the hydrophobic material 16 in the groove 12 can be made uniform.

このように、ブルドーザ５１を所定速度で走行させる運転手と、溝形成位置に沿って地面上に配置された疎水材入り袋を作業デッキ部１９に載置する作業者と、作業デッキ部１９に載置された疎水材入り袋を開封してホッパー１８内に疎水材１６を投入する作業者との３人で地中への暗渠管１４の敷設作業を効率よく行うことができる。   In this manner, the driver who causes the bulldozer 51 to travel at a predetermined speed, the worker who places the hydrophobic material-containing bag disposed on the ground along the groove formation position on the work deck portion 19, and the work deck portion 19. The laying work of the underdrain pipe 14 into the ground can be efficiently performed by three persons, who are the operator who opens the placed hydrophobic material-containing bag and inserts the hydrophobic material 16 into the hopper 18.

また、ホッパー１８の容積を、一般的な疎水材入り袋内の疎水材の量と同程度とし、従来に比べて大幅に小さく形成することにより、ホッパー１８内への疎水材１６の投入と、疎水材充填部１７から溝１２内への疎水材１６の充填とが連続して行われるため、ホッパー１８内に投入された疎水材１６が圧密されることはなく、特に、左右の側壁１８ｂ，１８ｂをホッパー１８の内方に向かって凸となる曲面で形成することにより、疎水材撹拌部材３１を設けなくてもホッパー１８内の疎水材を疎水材充填部１７に向けて円滑に落下させることができるので、ホッパー１８内で疎水材１６が詰まって溝１２内への疎水材１６の投入不良を生じることがなくなる。さらに、大型のホッパーのように、疎水材を投入するためのクレーンなどを必要とせず、疎水材投入のための停止も必要なくなるため、圃場への溝形成を効率よく行うことができる。   Also, by making the volume of the hopper 18 approximately the same as the amount of hydrophobic material in a general hydrophobic material-containing bag and forming the volume significantly smaller than in the prior art, charging of the hydrophobic material 16 into the hopper 18; Since the filling of the hydrophobic material 16 from the hydrophobic material filling portion 17 into the groove 12 is continuously performed, the hydrophobic material 16 introduced into the hopper 18 is not consolidated, and in particular, the left and right side walls 18b, By forming 18 b with a curved surface which is convex toward the inside of hopper 18, the hydrophobic material in hopper 18 can be smoothly dropped toward hydrophobic material filling portion 17 without providing hydrophobic material stirring member 31. This prevents the hydrophobic material 16 from being clogged in the hopper 18 and causing the charging failure of the hydrophobic material 16 into the groove 12. Furthermore, unlike a large hopper, it does not require a crane or the like for throwing in a hydrophobic material, nor does it require a stop for throwing in a hydrophobic material, so that grooves can be formed in the field efficiently.

なお、暗渠管押圧部材や疎水材高さ設定部材における高さ位置調節手段は、前記形態例に記載したものに限らず、ボルトやピンなどを用いた適宜な固定手段を採用することができる。   In addition, the height position adjustment means in the underdrain pipe pressing member and the hydrophobic material height setting member is not limited to the one described in the embodiment, and an appropriate fixing means using a bolt, a pin or the like can be adopted.
