【考案の詳細な説明】
本考案は、方向修正可能にした管理設用掘進機に関する
ものである。[Detailed Description of the Invention] The present invention relates to an excavator for management and construction that is capable of adjusting its direction.
この種の管理設用掘進機は第１図に示すように、揺動ジ
ヤツキ１の作動により、球面支持部材２を介してカッタ
ドラム３が揺動可能になっている。As shown in FIG. 1, in this type of excavator for management construction, a cutter drum 3 is swingable via a spherical support member 2 by the operation of a swinging jack 1.
またこのカッタドラム３は減速機４ａを介して油圧モー
タ４にて回転され、掘削した土砂は水パイプ５より送ら
れてきた水によりスラリ化され、スラリバイブロで発進
立坑へ送られるようになっている。The cutter drum 3 is rotated by a hydraulic motor 4 via a speed reducer 4a, and the excavated earth and sand is slurried by water sent from a water pipe 5, and sent to the starting shaft by a slurry vibro. There is.
ところが従来の管理設用掘進機はカッタドラム３の径が
本体７の径と同じか、少し大きくなっていた。However, in conventional maintenance construction excavators, the diameter of the cutter drum 3 is the same as or slightly larger than the diameter of the main body 7.
このため、従来のカッタドラム３では土砂を掘削し推進
していく際にまわりの土砂をもくずしてしまって、方向
修正するときに、第２図、第３図に示すように、くずし
た土砂がカッタドラム３の回転により下側へ敷きつめて
しまい、これによってヘッド本体７が上方へ移動しやす
くなって方向修正に悪影響を及ぼす。For this reason, when the conventional cutter drum 3 excavates and propels the earth and sand, it breaks up the surrounding earth and sand. Due to the rotation of the cutter drum 3, the head body 7 tends to move upward, which adversely affects direction correction.
本考案は上記のことにかんがみなされたもので、カッタ
ドラムの径をヘッド本体の径より小さくすると共に、本
体の先端にテーパ状の肩部を設けることにより、この肩

カッタドラム周囲の土庄が均等になるようにして、カッ
タドラムが揺動した分だけヘッド本体に逆方向の土圧が
発生してヘッド全体の向きをスムーズに変えることがで
きるようにした管理設用掘進機を提供しようとするもの
である。The present invention was developed in consideration of the above-mentioned issues.The diameter of the cutter drum is made smaller than the diameter of the head body, and a tapered shoulder is provided at the tip of the body. The difference in diameter of the main body is compacted to make the soil around the cutter drum even, and as the cutter drum swings, earth pressure in the opposite direction is generated on the head main body, smoothly changing the direction of the entire head. The purpose of the present invention is to provide an excavator for management and construction that can perform the following tasks.
以下その構成を第４図以下に示した実施例に基づいて説
明する。The configuration will be explained below based on the embodiment shown in FIG. 4 and below.
なお図中従来例と同一部材は同一符号にて示す。In the drawings, the same members as in the conventional example are indicated by the same reference numerals.
カッタドラム３′はその径をヘッド本体７′の径より小
径にしである。The cutter drum 3' has a diameter smaller than that of the head body 7'.
その径の差の例をあげると、ヘッド本体７′の径が３７
０ ｍｍφに対してカッタドラム３′の径が３３Ｑ ｍ
ｍφ、あるいは同様に２２０ ｍｍφに対して１９Ｑｍ
ｍφである。To give an example of the difference in diameter, the diameter of the head body 7' is 37
The diameter of cutter drum 3' is 33Q m for 0 mmφ.
mφ, or similarly 19Qm for 220 mmφ
It is mφ.
上記ヘッド本体７′の先端にはテーパ状の肩部８が形威
しである。A tapered shoulder portion 8 is featured at the tip of the head body 7'.
なおこのヘッド本体７′の先端には従来例と同様に水パ
イプ５とスラリバイブロが開口しである。Note that a water pipe 5 and a slurry vibro are opened at the tip of the head body 7' as in the conventional example.
しかして直進する場合にはカッタドラム３′とヘッド本
体７′の径の差だけヘッド本体７′の肩部８で圧密され
てカッタドラム３′の周囲の土庄が均等になり、令弟６
図に示すようにカッタドラム３′を下方へ揺動すると、
テーパ状に形成したヘッド本体７′の肩部８の上側部に
その揺動した分だけ土庄が発生し、ヘッド全体の向きが
下方へ変えられる。However, when moving straight, the difference in diameter between the cutter drum 3' and the head body 7' is consolidated by the shoulder 8 of the head body 7', and the area around the cutter drum 3' becomes even.
When the cutter drum 3' is swung downward as shown in the figure,
A bulge is generated on the upper side of the shoulder portion 8 of the tapered head body 7' by the amount of the swing, and the direction of the entire head is changed downward.
本考案は以上のようになり、ヘッド本体７′の先端側に
回転可能に、かつ軸心に対して揺動可能にしたカッタド
ラム３′を設けた管理設用掘進機において、カッタドラ
ム３′の外径をヘッド本体７′の外径より小径にすると
共に、ヘッド本体７′の先端にテーパ状の肩部を設けた
から、方向修正時にカッタドラム３′が揺動した分だけ
この揺動方向とは逆側のヘッド本体７′の肩部８に土圧
力が発生して方向修正をすムースに行うことができる。The present invention is as described above, and the cutter drum 3' is provided in an excavator for maintenance work in which the cutter drum 3' is rotatably provided on the tip side of the head body 7' and is swingable about the axis. The outer diameter of the cutter drum 3' is made smaller than the outer diameter of the head body 7', and a tapered shoulder is provided at the tip of the head body 7'. Earth pressure is generated on the shoulder 8 of the head main body 7' on the opposite side, so that direction correction can be carried out smoothly.

３′はカッタドラム、７′はヘッド本体、８は肩部。Fig. 1 is a sectional view showing a conventional example, Figs. 2 and 3 are explanatory diagrams showing a direction correction state in the conventional example, and Fig. 4 and the following show embodiments of the present invention. Fig. 4 is a sectional view. FIG. 5 is a front view, and FIG. 6 is an explanatory diagram showing a direction correction state. 3' is the cutter drum, 7' is the head body, and 8 is the shoulder.
