プに関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention involves excavating earth and sand, simultaneously forming it into a lump having a cross-sectional shape almost the same as the cross-section of the transport pipe of an air chute, and sucking this into a lump through the air chute. The present invention relates to a method for excavating and transporting earth and sand, and a shovel for excavating and forming earth and sand for carrying out this method.
地下で掘削した土砂を地上に送り出す装置として、イジ
ェクタ−式バキュームポンプを用いたエアーシュータが
用いられている。An air shooter using an ejector-type vacuum pump is used as a device for sending earth and sand excavated underground to the surface.
この種のエアーシュータは掘り起こした土砂を吸引して
上方へ運搬するものであるが、従来は不定形（ばらばら
）の土砂を比較的大口径のエアーシュータから吸引して
いるため吸引力のロスが大きく、効率の良い作業が期待
できなかった。This type of air shooter sucks up the excavated earth and sand and transports it upwards, but in the past, irregularly shaped (separate) earth and sand were sucked through a relatively large-diameter air shooter, resulting in loss of suction power. I couldn't expect the work to be large and efficient.

掘削・搬送方法を提供することにある。The object of the present invention is to provide a method for excavating and transporting earth and sand that can simultaneously excavate earth and sand and shape it into a shape that is easily sucked from an air chute, thereby improving the work efficiency of excavating and lifting earth and sand. It's about doing.
本発明の他の目的は上記方法を実施するための土砂掘削
成形スコップを提供することにある。Another object of the present invention is to provide an earth and sand excavation molding shovel for carrying out the above method.

達成することができる。The first object of the present invention is to simultaneously excavate the earth and sand, form the earth and sand into a lump with a maximum cross-sectional shape that is approximately the same as the cross-sectional shape of the transport path of the air chute, and transport the obtained earth and sand through the air chute. This can be achieved by suctioning and feeding from the tip of the tube.

て達成することができる。In addition, another object of the present invention is to provide a shovel made by integrally mounting a hollow excavation molding frame having a tapered inner peripheral wall from the tip opening side toward the rear at the lower part of the handle member that serves as a handle. It comprises a main body and an extrusion member having a tread plate fixed to the upper part and a press plate fixed to the lower part, and the extrusion member is slidably attached to the scoop body so that the press plate moves with a piston into the excavation forming frame. Excavation of earth and sand can be achieved by forming a shovel.

少ない場合は土中に押込んだ状態で押出し部材の踏み板
を踏んで荷重をかけると成形枠内の軟弱土砂は成形枠内
で押しかためられる。As described above, the present invention has a hollow excavation forming frame on the tip side of the handle member, and by pushing this into the earth and sand, the earth and sand enters the forming frame. If the earth and sand are soft or have low viscosity, when the earth and sand are pushed into the soil and a load is applied by stepping on the footboard of the extrusion member, the soft earth and sand in the forming frame will be compressed within the forming frame.
従って、スコップを地中から引き抜くと、土砂は成形枠
内に結め込まれた状態で採取され、掘削がなされる。Therefore, when the shovel is pulled out of the ground, the earth and sand are collected while being tied inside the forming frame, and excavation is performed.

踏み板を踏むとプレス板によって成形枠の土砂が所定の
形で押し出される。The inner circumferential wall of the hollow excavation forming frame of the shovel is formed into a tapered shape that tapers upward (rearward), so when the footboard of the extrusion member is stepped on, the earth and sand in the forming frame is pushed out in a predetermined shape by the press plate.

のロスを少なくして外部へ揚送することができる。The cross-section of the frame of the shaping scoop is adapted to the cross-sectional shape of the chute of the air shooter, so when excavating the earth and sand, it is possible to obtain molded earth and sand in a shape that matches the air shooter, and by sucking this into the air shooter. It can be transported outside with less loss of suction power.
スプリングにより押出し部材を上方位置に付勢させた場
合はプレス板のピストン操作がし易くなる。When the pushing member is biased to the upper position by the spring, it becomes easier to operate the piston of the press plate.
以下、図面を参照して本発明の詳細な説明する。Hereinafter, the present invention will be described in detail with reference to the drawings.

In this embodiment, as shown in FIG. 2, the through holes 4 are bored in the clay wall 2c of the forming frame 2, but they may also be bored in a part of the side wall 2t) of the forming frame 2. In particular, when a large amount of water enters the molding frame 2, it is preferable to provide a through hole 4 in the side wall 2b to allow the water to escape laterally, since the water will be sprayed toward the body of the worker above during excavation.
柄部材３には掘削、引抜きに便利なように一対支柱３ａ
の上部に横方向の取手３ｂがついている。The handle member 3 has a pair of supports 3a for convenient digging and extraction.

断面山形に形成するのが望ましい。In the illustrated embodiment, the shaft 5a of the extrusion member 5 is slidably supported by a cylindrical guide 7 integrated with the bracket 6 above the forming frame 1, and the extrusion member 5 is supported by a spring 8 provided between the bracket 6 and the footboard 50. Upper position (outer position) of reciprocating movement
It is intended to be energized. Further, the press plate 5b is desirably formed into a conical or mountain-shaped cross section with the apex facing upward in order to increase its own strength and to improve soil separation during earth and sand discharge.

A gap 9 is formed in the peripheral wall of the transport pipe 9a, leading from the suction port 9b into the pipe.
c are provided in multiple stages, and the air inside the pipe is sucked by a pump (not shown) provided above the transport pipe 9a.

押し込む。Thus, in the present invention, the cylindrical excavating blade 2a at the tip of the molding frame 2 is brought into contact with the ground, and the molding frame 2 is pushed into the ground by applying weight to the handle. If the soil is soft, use the footboard 5C of the pushing member 5.
Step on to harden the earth and sand inside the molding frame 2, and push the molding frame 2 further.
成形枠２内に所定の土砂が詰ったら土砂ごとスコップ１

出す。When the molding frame 2 is filled with the specified amount of earth and sand, scoop 1 with the earth and sand.
, and by stepping on the footboard 5C, etc., the internal earth and sand lump 10 is pushed out by the relative movement of the push-out member 5 and the shovel body 1.

に吸上げられる。The earth and sand mass 10 excavated and formed in this way is sent upward from below the transport pipe 9a of the vacuum pump 9 using a vacuum pump 9 with an inner diameter that matches the mass, as shown by the imaginary line in FIG. . In this case, the earth and sand mass 10 is preliminarily moved by a vacuum pump transport pipe 9 so that it receives a large suction force.
Since it matches the inner diameter of a, there is little loss of suction power (it is sucked up strongly).

で軟弱な地盤でも使用が可能である。As described above, the present invention enables the transportation of the pump with less loss of suction power when excavating deep underground using a notebook vacuum pump, etc., which automatically shapes the excavated earth and sand into a predetermined shape at the same time as excavating the earth and sand. You can maximize your power. In particular, it can be used even in soft ground because it can excavate while pushing down the earth and sand.
また、垂直方向から土砂を掘削できるので場所を取らず
、作業スペースのせまい場所の掘削に便利である。In addition, since earth and sand can be excavated vertically, it does not take up much space, making it convenient for excavating in areas with limited work space.
