Conventionally, when trying to demolish a house, for example, a gripping device such as a double-opening claw was equipped at the end of the arm, the house was demolished, the rough scraps were transferred to a truck using the gripping device, and the remaining small pieces of waste were picked up by the end of the arm. They replaced the ends with buckets, scooped them up, and loaded them onto trucks. According to this traditional method, as the work progresses,
Each time, it is necessary to replace the bucket at the end of the heavy arm, which reduces work efficiency and requires a lot of labor. On the other hand, there are also examples of installing cylinders on the outside of the bucket to make it multi-functional, but there are problems with durability as the cylinders are easily broken, and the need for multiple cylinders increases costs. Issues were also raised from both sides. Therefore, we installed a fork near the base attachment shaft of the bucket, which is attached to the end of the arm of a construction machine such as a power shovel and connected to the bucket cylinder via a link, so that it can hold objects between it and the bucket, and inside the base of the bucket body. A bucket hand of a construction machine that can open and close the fork by attaching an opening/closing cylinder to it; construction of a structure in which the bucket is connected to the bucket, an opening/closing cylinder is installed in the base of the bucket body, the fork is connected, the bucket and the fork can be opened both ways, and the bucket is connected to the bucket cylinder provided on the arm side via a link. A mechanical bucket hand was developed and proposed in Japanese Patent Application No. 2-110658. When this device is used with a fork attached to the bucket, it can be used with the same scooping function as using a conventional bucket. In addition to this function, when used with the bucket and fork open and closed, it becomes a one-sided or double-opened state, and has a gripping function that allows scrap materials to be pinched and dismantled, moved, loaded, etc. . In addition, the opening/closing cylinder is installed in the bucket body without fear of damage, and is provided as a single item, thereby achieving durability and cost reduction.

The proposed structure does not have a central portion of the fork (3), and is gripped only by the side wall portion of the bucket. Although this structure does not interfere with scooping with a bucket, it is inefficient and difficult to grasp. In addition, the fork was completely removable and had to be installed and removed, which was inconvenient, and there were other problems that needed to be resolved, such as the loss of the fork and the need to store it.

Further, the cylinder mooring means (11) tethers and holds the fork opening/closing cylinder (6) to the bucket bracket, and the position of the connecting pin when connecting the fork (3) and the fork opening/closing cylinder (6) during the gripping operation. Can be matched. In the case of grasping operations, the mooring means (10) of the fork (3)
By removing this and connecting the fork opening/closing cylinder (6) to the boss (9) near the arm base, the bucket (2
) and the fork (3) can be opened and closed. Since a large number of forks (3) (for example, 4) can be used to cover the entire area including the inside of the bucket opening, the effect of the knob is great. These effects are due to the fact that the fork (3) is rotatably attached to the arm end boss (7) so that it can rotate independently of the bucket (2). [Examples] Examples of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a side view of the bucket hand of the present invention;
