In the general mounting method in which a worker removes and inserts the pins 14 and 15 to attach and detach the operated attachment, a sledgehammer is used to insert and remove the pins, which requires heavy lifting, and when the pins become rusty, they are difficult to remove. It is difficult to position the pin when inserting it, and it takes time to attach and detach.
Two workers are required to insert and remove the pin. In addition, the pin is heavy and dangerous when removed, and furthermore, if the pin is unstable when removed, the attachment may flip back, which is dangerous. Further, when inserting the pin, there are problems such as damage to the seals attached to the pin insertion portion of the arm 3 and the second link 9.

Next, we will discuss the effect. In FIG. 2, when one packet cylinder 7 is extended to excavate with the packet 4, for example, the second link 9 and pin 18 are pushed to the right, and the supporting side plate 16 rotates clockwise around the pin 17. try to. From this point on, the engagement notch 16b presses the engagement pin 20 of the packet 4 to the right, and the packet 4
rotates clockwise around the pin 17 together with the support plate 16. Excavation is performed in this way.

Conversely, when the bucket cylinder 7 is retracted, the second link 9
, the pin 18 is pulled to the left, and the support plate 16 is pulled to the left by the pin 17.
Try to rotate counterclockwise around the center. This results in
Since the clamp 21 also moves to the left together with the support plate 16, the pin hole 2ib of the clamp 21 pulls the engagement pin 20, so the packet 4 moves together with the support plate 16 and pulls the pin 17. The excavated earth and sand in the packet 4 can be discharged by rotating counterclockwise around the center. Second
As shown in the figure, since the engagement pin 20 is fixed so that the stepped half surface portion 20a is substantially perpendicular to the opening notch 21c of the clamp 21, the clamp 21 will not come off from the engagement pin 20 during work. Not at all.

(3) There is no need to insert or remove pins, and the only manual work required is tightening the bolts, so there is no need for manual labor, overhanging, rusting of pins, or damage to seals, making it safe for only one worker. Moreover, it can be attached and detached in a short time.

(4)支持囲板の係合用切欠きの案内部を大きく取れば
位置決めが容易である。
(4) Positioning will be easier if the guide portion of the engagement notch in the support shroud is made larger.

(5)作業中クランプが外れることがないので、アタッ
チメントの脱落事故はなく、安全である。
(5) Since the clamp does not come off during work, there is no accident of the attachment falling off, and it is safe.

(6)土砂の噛込みや、錆つきなどにより、作動不良を
おこす心配がない。
(6) There is no need to worry about malfunctions caused by dirt or rust.
