Abstract

PURPOSE:To improve the scooping and excavation capability by disposing a cylinder drive open and close link and coupling a bracket to a bucket cylinder through an arm and an angle adjust link in a bucket unit such as a hydraulic power shovel. CONSTITUTION:Buckets 11, 15 are levated by an arm 1. When a rod 3 of a bucket cylinder 2 is contracted, an auxiliary rod 10 and a pivotal rod 7 are turned on an arm pin 6 clockwide to rotate the buckets 11, 15. The rods 10, 7 are reversed by expanding the rod 3, thereby adjusting the swing angle of the buckets 11, 15. Left and right links 24, 25 are opened and closed by expanding and contracting a rod 23 of an open and close cylinder 22, and the buckets 11, 15 are turned on left and right support pins 14, 18 of an arm 4 by movement of left and right open and close support plates 27, 29 to be opened and closed. This arrangement can improve the scooping and excavation force and the work efficiency of adjusting a bucket angle.

When the rod (3) of the packet cylinder (2) is retracted, the arm pin (4) is pivoted, and the packet (11, 15) is rotated clockwise by the clockwise rotation of the auxiliary rod QG and the rotating rod (7). rotate around. Conversely, extending the rod (3) will rotate the packet counterclockwise. That is, by expanding and contracting the packet cylinder (2), the angle (swing angle) of the packet with respect to the vertical line can be adjusted.

Furthermore, if the rod (c) of the opening/closing cylinder is extended from the state where the packet is completely opened, the left and right opening/closing links (24.degree. 25) will open around the main bin (a) which is descending. Therefore, since the left and right opening/closing support plates (27, 29) are pushed down via the left and right opening/closing bins (28, 30), the left and right brackets (11, 15) are
8) and rotate in opposite directions to close.

As mentioned above, the left and right opening/closing bins (28, 30) are located outside the left and right supporting bins (14, 18), respectively, so when the opening/closing cylinder rod (A) is expanded or contracted, the opening/closing packet is The elastic force is the opening/closing link (24, 25)
, circles centered around the support bins (14, 18) and having radii between the left support pin 04), the left opening/closing bin (c), and the right support pin α and the right opening/closing bin (g), respectively. Since a strong torque is applied in the tangential direction of the packet, the opening and closing force of the packet is extremely strong. Therefore, the gripping force and digging force when closing the left and right packets are extremely strong, and in the fully closed state, the extension force of the opening/closing cylinder becomes a torque when closing the packets, so no sludge leaks.

As described above, the packet device according to the present invention has extremely strong gripping force and digging force, and the packet position can be easily adjusted, so it is effective for demolition of buildings, excavation, and sludge treatment work. If the packet is attached to the arm in a direction perpendicular to the embodiment, it is convenient for digging ditches on narrow forest roads. Furthermore, it can of course be used as a conventional crumb packet by attaching the tip of the arm to the upper bin of the bracket via a universal joint.
