(Prior art and its problems) It is necessary to excavate concrete driving holes used for the foundation of construction and construction, and other circular holes in the ground. Since an excavator with a bucket-type excavator does not have a circular drilled hole, this type of excavation work is usually done with an excavator equipped with excavating blades at regular intervals along the lower edge of the cylinder. There is. With this method, the cylinder itself has no means for removing the excavated earth and sand, so there is the inconvenience that it must be used alternately with a normal bucket type excavator, and the top of the cylinder itself is rotated by a rotating machine. Since the cylinder body is only pushed into the soil while being carried out, the excavation capacity of the cylinder body is not so large and the efficiency is very low.

The support plate 1'constituting the lower end of the support arm 1 has axes parallel to each other which are horizontally equidistant from the center of the apparatus.
Support brackets 5 and 5 to which the half buckets 2 and 2 are fixed are pivotally attached by P1 and pivot shafts 4 and 4 on P1. The brackets 5 and 5 have pivot shafts 6 and 6 on the second axes P2 and P2.
Thus, the lower ends of the drive arms 3 and 3 are pivotally attached. Therefore, when the drive arm moves up and down, the brackets 5 and 5 and the half buckets 2 and 2 integrated with them between the solid line position and the chain line position shown in the figure swing around the axes P1 and P1. Stoppers 7, 7 are provided on the upper ends of the brackets 5, 5.
Is formed, whereby the open position of the half buckets 2 and 2 is regulated. On the other hand, the closed position of the half bucket is regulated by abutting the lower edges of the half bucket as described below. The bucket device is lowered into the drill hole when the half bucket is in the open position, and when the bottom of the hole is reached, the half bucket is closed to cut the soil at the lower edge of the half bucket and perform a predetermined circular drilling. The excavated soil can be discharged by pulling it up while trapping the soil in a closed bucket.

Next, the structure of the half buckets will be described. The half buckets 2 and 2 are arranged in a mirror image relationship on both sides of the plane M in FIG. 3 and have the same shape. Each half-bucket has a semi-cylindrical shape, and has a generally cylindrical shape in the open position shown in FIG. 3 (see also FIGS. 3 and 5 together), and is located below the axes P1 and P1. It has a lower portion extending and an upper portion extending upward. The lower part terminates in an inclined lower edge 7. The inclination of the lower edge is almost straight when seen in FIG.
The tilt angle measured from is just equal to the swing angle between the open and closed positions of the half-bucket, and the downwardly extending length of this cylindrical portion is just the bottom edge of the half-basket in the closed position. Such a length (see FIG. 6).

The cylindrical upper part of each half-basket 2, 2 is curved inwardly at the central part of the upper edge (as seen in FIG. 4) (third part).
(See the drawing) An auxiliary plate 8 is provided. This auxiliary plate 8 is necessary for restricting the outermost diameter of the bucket with a diameter slightly smaller than the cylindrical surface of the half bucket and for holding the excavated soil when the buckets 2, 2 are brought to the closed position. As shown in FIG. 4, the upper edge 9 of the upper part is also curved in the closed position so as to restrict the slightly smaller outermost diameter of the bucket. The inner edge 10 of the half bucket is vertical in the open position. A leading excavating blade 11 is attached to the lower edge of the half bucket.

(Operation and effect) When the bucket device is in use, the half-bucket is soiled when the hole that has already been drilled is lowered while the cylindrical wall that has already been drilled is being corrected while the half-bucket is in the open position and the bottom of the hole is reached. Bite into. However, at this time, since there is a large gap between the inner edges 10 of the pair of half buckets (see FIG. 5), excavation of this portion is not performed, and the half buckets 2 and 2 are continuously moved to the drive arms 3 and Closing by 3 allows the lower edges 7, 7 and the inner edge 10 of the half bucket to bite into the soil in this part for excavation. This area is not a circle but an almost straight excavation surface, which is not sufficient for excavation of earth and sand. In the fully closed position, the upper and lower edges 9 and 10 of the half-bucket and the surfaces of the auxiliary plate 8 are generally slightly smaller than the open cylindrical shape. If the bucket device is pulled up in this state, the bucket device can be pulled up without much resistance, and if there is any disturbance on the inner surface of the drill hole, this is corrected.
