とを特徴とする水圧利用の土中穿孔機にある。 The purpose of the present invention is to provide a drilling machine that can be attached to the tip of a hydraulic hose to easily perform drilling in the above-mentioned cases. It consists of a rotating body rotatably supported at the front part of the shaft, and the rear end of the shaft has a water passage part that is inserted into the tip of the hydraulic hose, and a large number of water fountain holes that are inclined in the circumferential direction. The rotary body is provided with a large number of water receiving holes inclined in the opposite direction to the water fountain holes, and a plurality of cutters are attached to the surface of the rotating body. There is a soil drilling machine in use.
以下、図示の一実施例に基いて本考案を具体的
に説明する。 Hereinafter, the present invention will be specifically explained based on an illustrated embodiment.
軸体１は細長い通水部２とその先端に一体に設
けた頭部３とで構成され、通水部２の後端は水圧
ホース４の先端に嵌挿されるようになつている。 The shaft body 1 is composed of an elongated water passage part 2 and a head 3 integrally provided at its tip, and the rear end of the water passage part 2 is adapted to be fitted into the tip of a hydraulic hose 4.
回転体５は円板状の基部６の前後にそれぞれ突
出部７と円筒部８を突設したもので、円筒部８は
その内部に挿入した軸体１の前方部にベアリング
９を介して回転自在に支持されている。 The rotating body 5 has a protruding part 7 and a cylindrical part 8 protruding from the front and rear of a disc-shaped base 6, respectively, and the cylindrical part 8 is rotated via a bearing 9 on the front part of the shaft 1 inserted therein. freely supported.
頭部３には周方向に傾斜した多数の噴水孔１０
が穿設され、また基部６には噴水孔１０と逆向き
に傾斜した多数の受水孔１１が穿設され、噴水孔
１０の出口と受水孔１１の入口が一致したとき、
これらの孔を通水部２から送られた圧力水が通
り、この際に基部６が受ける水圧で回転体５が回
転するようになつている。 The head 3 has a large number of water fountain holes 10 inclined in the circumferential direction.
is drilled in the base 6, and a large number of water receiving holes 11 are bored in the base 6, which are inclined in the opposite direction to the water fountain holes 10, and when the outlet of the water fountain hole 10 and the entrance of the water receiving hole 11 coincide,
Pressure water sent from the water passage section 2 passes through these holes, and the rotating body 5 is rotated by the water pressure that the base 6 receives at this time.
突出部７の前部にはドリル状のカツター１２と
チツプ状の縦カツター１３及び横カツター１４が
装着され、基部６にもチツプ状の縦カツター１５
及び横カツター１６が装着されている。 A drill-shaped cutter 12, a tip-shaped vertical cutter 13, and a horizontal cutter 14 are attached to the front part of the protrusion 7, and a tip-shaped vertical cutter 15 is also attached to the base 6.
and a horizontal cutter 16 are attached.
なお、図中、１７と１８はベアリング９の背後
において通水部２の外周と円筒部８の内周にそれ
ぞれ取付けたストツパー、１９は円筒部８の外周
に設けた誘導用の螺旋溝、２０は通水部２の後方
部外周に取付けた案内兼回転防止棒である。 In addition, in the figure, 17 and 18 are stoppers attached to the outer periphery of the water passage part 2 and the inner periphery of the cylindrical part 8, respectively behind the bearing 9, 19 is a spiral groove for guiding provided on the outer periphery of the cylindrical part 8, and 20 is a guide/rotation prevention rod attached to the outer periphery of the rear portion of the water passage section 2.
前述の穿孔機を用いて穿孔を行う場合は、水圧
ホース４の先端に軸体１の通水部２の後端を接続
し、水圧ホース４に図示しないポンプから圧力水
を供給し、前述のようにしてカツター付きの回転
体５を回転させるとともに、受水孔１１から水を
噴出させて土を掘削し、掘削が進むにつれて水圧
ホースを送り出して、土中深く掘削孔を形成す
る。 When drilling using the above-mentioned drilling machine, connect the rear end of the water passage part 2 of the shaft body 1 to the tip of the water pressure hose 4, supply pressure water to the water pressure hose 4 from a pump (not shown), and perform the above-mentioned drilling. In this way, the rotary body 5 with a cutter is rotated, water is ejected from the water receiving hole 11 to excavate the soil, and as the excavation progresses, a hydraulic hose is sent out to form an excavated hole deep in the soil.
