を採っている。In prior art Utility Model Publication No. 1-44635, the brush material and the outer and inner protection plates of the brush material are held between the brush material holding hardware, and at the same time, the check plate is attached to the outer surface of the proximal end of the outer holding plate. The base end portions are stacked and held together by the holding hardware.

間どっている現状にある。Problems to be Solved by the Invention In the above-mentioned tail seal brush material, since the check plate is sandwiched together with the seal brush material and the inner and outer protection plates, the amount of brush material installed is limited accordingly, and the shield brush material is used as much as possible. Not only does this go against the desire to increase the amount of plants planted, but
When building a body structure by passing a bottle or bolt through the inner and outer metal fittings that hold the seal brush material, it is necessary to align the mounting hole of the outer protection plate with the mounting hole of the check plate that overlaps the outer surface of the outer protection plate. The current situation is that it is extremely time consuming to insert the bottle or bolt due to misalignment.

を繰り返して折損を生ずる問題を有している。In addition, the check plate freely bends inward and outward during use at the portion along the inner surface of the free end of the outer holding metal of the brush holding metal, and at this time, the bent portion of the check plate collides with the inner corner of the outer holding metal. This has the problem of repeated breakage.
本発明は上記の問題を有効に解決することを目的として
いる。The present invention aims to effectively solve the above problems.
問題点を解決するための手段

面に上記逆止板の基端部を固着して地山へ向け延設して
上記テールシールブラシを構成したものである。As a means to solve the problem, the present invention eliminates the means of clamping the check plate together with the sealing brush material to the brush holding metal fittings and fastening them to the brush holding metal fittings, and the free end of the outer holding metal fittings of the brush holding metal fittings is removed. The tail seal brush is constructed by fixing the proximal end of the check plate to the inner surface of the base and extending it toward the ground.
作用

のシールブラシ材を保持金物に植装することができる。Function: The check plate is not clamped by the brush holding metal fittings, but is fixed to the inner surface of the free end of the outer holding metal fittings forming the brush holding metal fittings, so that more seal brush material can be used in the limited space of the tail section of the excavator. Can be implanted in holding hardware.
又逆止板は基端をブラシ保持金物の外側保持金物の自由
端部内面側に固着しているので、使用時同外側保持金物

。In addition, since the base end of the non-return plate is fixed to the inner surface of the free end of the outer holding metal of the brush holding metal, during use, the check plate repeatedly bends on the inner surface of the free end of the outer holding metal. The problem of breakage due to contact with the inner corner can be effectively solved.

The brush holding hardware 1 holds the base of the seal brush material 2, and at the same time holds the base of the outer protection plate 4 superimposed on the outer surface of the seal brush material 2 and the inner protection plate superimposed on the inner surface thereof. The inner holding hardware 6 of the brush holding hardware 1 is held together with the brush material.
A pin 10, a bolt, or a rivet is passed through the mounting hole 8.9 of the inner and outer protection plates and the seal brush material 2 between the inner and outer holding hardware 7, and for example, the pin end is connected to the inner and outer holding hardware 6.7.

の流入を阻止するようにする。The outer holding hardware 7 of the brush holding hardware 1 that holds the seal brush material has a free end that does not restrain the seal brush material, and this free end forms a mounting seat 11 for the check plate 5, and the other end is a non-return check plate. A mounting seat piece 20 with a mounting hole 18 provided at the base end of the plate 5
The base end of the check plate 5, that is, the mounting seat piece 20, is fixed to the inner surface of the end mounting seat 11 of the outer holding hardware 7, and the fixed part is extended toward the ground. and prevent the backfill material from flowing into the face side.

On the other side, as shown in the figure, the base end of the check plate 5 attached to the end mounting seat 11 is attached with a pin 12, a bolt, or a rivet. in this case,
A mounting hole 18 is provided at the base end of the check plate 5.
The periphery of the flange 14 is raised in an annular shape to form a flange 14, and the flange 14 is fitted into the inner surface of the mounting hole 13 provided in the mounting seat 11, and the pin 12 is inserted into the flange 14 so as to be integrally mounted.

Direct to the outside of the body. When extruding the segment, the inner and outer protection plates 3.4 are pushed up against the elasticity, but at this time, the outer protection plate 4 hits the above-mentioned]-shaped bent portion 15 and stores elasticity, and the tip of the seal brush material is pushed up against the outer peripheral surface of the segment. Press harder.

ことができる。Effects of the invention In the tail seal brush having the above structure, the check plate is not held in the brush holding hardware, so the capacity of the seal brush material by the mounting hardware can be increased as much as possible, and the sealing effect can be improved. In this way, it is possible to effectively solve the problem of the check plate being bent freely on the inner surface of the free end of the outer holding hardware and repeatedly colliding with the inner corner of the free end, resulting in breakage.
