Description

[Detailed Description of the Invention] The present invention relates to a bucket device for a hydraulic excavator.

Conventional bucket carts of this type can excavate vertically by using a reversed bucket cart, but they cannot excavate horizontally and diagonally, making it difficult to use for corner cutting, etc. when excavating trenches on slopes. I also spent a lot of time working.

The present invention was developed in view of the above circumstances, and its purpose is to enable the bucket to rotate 360 degrees and to hold the bucket at a predetermined angle, making it easier to perform horizontal and diagonal excavation work. An object of the present invention is to provide a bucket equipment which can easily excavate slopes and improve work efficiency.

Hereinafter, the present invention will be explained with reference to the drawings.

In the drawings, reference numeral 1 denotes a fixed main body, and mounting brackets 2 and 3 are fixed to the rear end of the fixed main body 1.

A flange-shaped thrust receiving part 4 is provided on the periphery of the stationary side main body 1.
is formed. A rotating body 5 is rotatably attached to the periphery of the stationary body 1.
Thrust bearings 8 and 9 are interposed between the step portions 6 and 7 and the thrust receiving portion 4.

A plurality of angle index receiving holes 10 are formed at predetermined intervals in the circumferential direction on the front back surface 5a of the rotating body 5, and an internal gear 11 is formed on the circumference of the rotating body 5. .

A hydraulic motor 12 is fixedly installed on the stationary body 1, and a gear 14 is attached to a drive shaft 13 of the hydraulic motor 12. The gear 14 meshes with an internal gear 11, and these act as a rotational drive mechanism. It constitutes A.

Further, the fixed side body 1 is provided with a fixing cylinder 15, and the rod 16 of the fixing cylinder 15 is removably inserted into the angle index receiving hole 10, and these constitute a lock mechanism B. There is.

A bucket 17 is fixed to the rotating body 5.

Further, a rod 9 of a bucket cylinder 18 is connected to the mounting bracket 2 via a link mechanism 21, and an arm 20 is connected to the other mounting bracket 3.
are connected.

Then, the fixing cylinder 15 is actuated to remove the rod 16 from the angle index receiving hole 10 and unlock the rotating body 5.

Next, the hydraulic motor 12 is driven to rotate the rotating main body 5 via the gear 14 and the internal gear 11, and the bucket 17 is rotated.

After rotating the bucket 17 by a predetermined angle, the fixing cylinder 15 is actuated to move the rod 16 into the angle indexing receiving hole 10.
to fix the bucket 17 to the stationary body 1.

Therefore, it becomes possible to excavate laterally, vertically, and diagonally.

As described above, in the present invention, the rotating body 5 is rotatably provided around the periphery of the fixed body 1 attached to the arm side, and the center of rotation of the rotating body 5 is aligned with the axis of the fixed body 1. At the same time, the front back surface 5a of the rotating main body 5 is positioned in front of the fixed main body 1, and the front back surface 5a of the rotating main body 5 is positioned on a circle centered on the rotation center of the rotating main body 5. A plurality of angle index receiving holes 10 are provided at predetermined intervals over 360 degrees, and a rod 16 is removably inserted into the angle index receiving holes 10 in the fixed side main body 1. A cylinder 15 is provided, a bucket 17 is fixed to the front part of the rotating side main body 5, and the fixed side main body 1
The bucket bag device is characterized in that a rotary drive mechanism A for rotating the rotating main body 5 is provided.

Therefore, after operating the rotary drive mechanism A to rotate the bucket 17 by a predetermined angle within a range of 360 degrees via the rotating body 5, the fixing cylinder 15 is operated to move the rod 16 into the angle index receiving hole. By inserting the bucket tote 17 into the fixed body 1, the bucket tote 17 can be held at a predetermined angle.

Since the bucket 17 can thus be rotated 360 degrees and held at a predetermined angle, excavation can be performed laterally, vertically, and diagonally. Since this horizontal and diagonal excavation work becomes easier, it also becomes easier to perform cornering work in slope excavation and trench excavation, thereby improving work efficiency.
