（考案が属する技術分野）
本考案は地盤改良剤の撹拌混合で軟弱地盤を改
良するタイプの軟弱地盤改良装置における回転軸
のガイドに関するものである。[Detailed description of the invention] (Technical field to which the invention belongs) The present invention relates to a guide for a rotating shaft in a type of soft ground improvement device that improves soft ground by stirring and mixing a soil improvement agent.
（考案の課題とその特徴点）
回転軸の下端部に取付けた撹拌翼の作動で地盤
土壌と地盤改良剤とを撹拌混合するタイプの軟弱
地盤改良装置には、地中に貫入する回転軸の鉛直
性保持と座屈防止のために、ガイドが設けられて
いる。(Issues of the invention and its features) A soft ground improvement device of the type that stirs and mixes ground soil and soil improvement agent by operating a stirring blade attached to the lower end of a rotating shaft has a rotating shaft that penetrates into the ground. A guide is provided to maintain verticality and prevent buckling.
このガイドには施工機のリーダーに対して可動
のものと固定のものとがあるが（可動のものにつ
いては例えば実公昭60−2274号参照）、その何れ
の場合でも、２軸タイプ（回転軸が２本）の装置
のガイドには施工ピツチ（回転軸の軸間距離）に
等しい間隔で回転軸挿通部が設けられている。 There are two types of guides: movable and fixed with respect to the leader of the construction machine (for movable guides, see Utility Model Publication No. 60-2274, for example), but in both cases, the two-axis type (rotating axis The guide of the device (2 pieces) is provided with rotary shaft insertion portions at intervals equal to the construction pitch (distance between the rotary shafts).
施工ピツチに変更があると、これに応じて回転
軸挿通部の間隔も変更しなければならないが、従
来のガイドにおけるこの間隔の変更は、ガイド基
体の中央部の切断ないしは継足しでなされてお
り、非能率的かつ不経済的であつた。 If there is a change in the construction pitch, the spacing between the rotating shaft insertion parts must be changed accordingly, but in conventional guides, this spacing is changed by cutting or adding an addition to the center of the guide base. , it was inefficient and uneconomical.
本考案は、前述の回転軸挿通部の間隔変更を容
易に行うことができるように工夫したものであつ
て、その構成上の特徴は実用新案登録請求の範囲
に記載したとおりである。 The present invention has been devised so that the interval between the rotating shaft insertion portions described above can be easily changed, and its structural features are as described in the claims of the utility model registration.
すなわち、本考案のガイドでは、基体の前面に

とにより、可動式又は固定式の何れのタイプにも
することができる。 That is, in the guide of the present invention, the rotating shaft insertion body, which is separate from the base body, is attached to the front surface of the base body while changing its position in the lateral direction.
The above-mentioned interval can be easily changed. By attaching an appropriate engaging body for the leader to the rear side of the base, it can be made into either a movable type or a fixed type.
（図面による説明）

方向に等間隔に多数組のボルト孔３，…，３′，
…が穿設されている。(Explanation with drawings) In the illustrated embodiment, 1 is a base of the guide, and on both sides of the front vertical surface 2, there are many sets of bolt holes 3,..., 3', spaced at equal intervals in the lateral direction.
... has been drilled.
図示の場合は、１組のボルト孔が３個である
が、これに限らないことはいうまでもない。 In the illustrated case, there are three bolt holes in one set, but it goes without saying that the number is not limited to this.
４，４′は左右１対の回転軸挿通体であり、図

ない。 Reference numerals 4 and 4' denote a pair of left and right rotating shaft insertion bodies, and in the case shown in the figure, each rotation shaft insertion body includes a half bearing 5 and an asymmetrical half bearing 6 connected to this with bolts 7, 7. However, the half bearing 6 may be symmetrical to the half bearing 5, or one side may be hinged rather than bolted.
回転軸挿通体４，４′はそれぞれボルト孔３，
３′を利用してボルト８，８′により基体１に取付
けられる。 The rotating shaft insertion bodies 4 and 4' are respectively inserted into the bolt holes 3 and 4'.
3' and is attached to the base body 1 with bolts 8, 8'.
回転軸挿通体４，４′の間隔は図示の場合が最

まり、その変更は自由である。 The distance between the rotary shaft inserters 4, 4' is maximum in the case shown in the figure, and if this is to be reduced, the inner bolt holes 3, 3' may be used for mounting. That is,
The spacing between the rotary shaft inserters 4, 4' is determined depending on the horizontal position of the bolt holes 3, 3', and can be freely changed.
図示の実施例は可動式のものであり、基体１の
後側にボルト９で取付けられた係合体１０の先端

とにより固定式のものに変えることができる。 The illustrated embodiment is of a movable type, and the ends 11, 11' of the engaging body 10 attached to the rear side of the base 1 with bolts 9 are connected to the rails 13, 1 of the leader 12.
3', but by replacing the engaging body 10, it can be changed to a fixed type.
（考案の効果）
本考案のガイドは、以上のようなものであるか
