換が非常に困難となる。 As shown in Figure 1, excavated materials (e.g. earth and sand)
During excavation 14, the excavation bucket is pushed into the slope of the excavated object 14. At this time, since the width of the rear bucket cart 2 is larger than that of the arm, a space 15 is created at the rear of the rear bucket cart 2, and this space 15
Then, as shown in FIGS. 2 and 3, the excavated objects 14a and 14b on the sides collapse in the direction of arrow E. When the excavated objects 14a, 14b on this side collapse, the hose 7, the piston rod 8a of the tilt cylinder 8, the links 10, 11, the pins 4, 1

The head of the locking bolt and locking bolt was broken.
Or if they wear out, it becomes very difficult to replace the pins 4, 12, 9, 13.

ことを特徴とする。 This idea was created to eliminate the above-mentioned drawbacks, and includes a rear bucket belt that is tiltably supported by a pin at the tip of the arm, and a front bucket trunk that is supported by a pin so that the rear bucket can be opened and closed.
A bucket cylinder that opens and closes the front bucket is installed inside the rear bucket. A hose for supplying and discharging hydraulic oil is connected to the bucket cylinder, and one end of the tilt cylinder is connected to the rear bucket and the arm connection via links. This excavation bucket for a hydraulic excavator is characterized in that a protective plate is removably attached to the rear edge of the rear bucket so as to surround the tips of the hose, link, and arm from the outside.
以下、この考案の一実施例を第４図ないし第７
図により説明する。それらの図において、第１図
ないし第３図と同じ符号をつけたものは同じもの
を表わす。 An embodiment of this invention is shown below in Figures 4 to 7.
This will be explained using figures. In these figures, the same reference numerals as in FIGS. 1 to 3 represent the same parts.
リアバケツト２の後縁部には、ホース７、リン

ができる。 According to this invention explained above, the space 15 is blocked by the protection plate 16, and the excavated object 14 is protected from the side.
a, 14b will not collapse into the space 15. Therefore, during excavation, the tilt cylinder 8, hose 7, links 10, 11, pins 4, 1
Damage to the locking bolts 2, 9, and 13 can be prevented. Furthermore, since the protective plate 16 is removable, there is no problem in replacing the pins 4, 12, 9, and 13, and they can be easily replaced when they are deformed, and can be removed at will for unnecessary work.
