Hereinafter, these will be described in detail.

As shown in FIGS. 3 to 5, the base member 22 has a plate-like shape, and has a pair of ribs 25 provided on the back of the base member 22 to be attached to the arm 24 of the power shovel 23 by pins or screws. A large diameter base shaft 17 is attached to the lower center of the base member 22. Support members 15 and 16 are swingably attached to the base shaft 17, and extendable members 13 and 1 are attached to tips of the support members 15 and 16.
4 are attached. This elastic member 13, 1
4 comprises double cylinders 26, 27 each having a rectangular cross section having hydraulic cylinders 11, 12 inside, and by expanding and contracting the internal hydraulic cylinders 11, 12, double cylinders 26, 27 are provided.
Is designed to expand and contract. Attachment members 28, 29 are attached to the distal ends of the double cylinders 26, 27, and the supporting members 30, 3 are attached to the attachment members 28, 29 by pins.
1 is attached. The mounting members 28 and 29 are provided with a plurality of mounting holes for mounting the support arms 30 and 31, so that digging members having different sizes can be mounted.

As shown in FIGS. 5 and 6, hydraulic cylinders 20 and 21 are attached to the base ends of the telescopic members 13 and 14, respectively.
4 oscillates, and the excavating members 18 and 19 attached to the front sides of the elastic members 13 and 14 respectively rotate. Each of the excavating members 18 and 19 has a quarter spherical shell shape obtained by further reducing the hemispherical shell by half.
Excavation claws 32 and 33 made of a superalloy are provided at the lower inner end portion in the case where 19 is combined. And FIG.
As shown in FIG. 4, the left and right 1/4 spherical shell-shaped excavating members 1
A pair of connecting members 34, 35 rotatably connected by pins 34a, 35a are provided before and after the upper end portions of 8, 19, respectively.
Are provided so that the upper ends of the excavating members 18 and 19 can be detachably connected by pins. As shown in FIGS. 5 and 6, a plurality of auxiliary excavating members 36 and 37 are provided around the outer periphery of the excavating members 18 and 19,
7a are provided respectively. The auxiliary excavating members 36 and 37 are provided with a certain gap from the lower outer surfaces of the excavating members 18 and 19, so that the surrounding soil generated during excavation can be discharged upward. .

Therefore, when the tree excavator 10 is used, first, the base member 22 is connected to the power shovel car 23.
It is attached to an arm 24 (usually referred to as a heavy machine), and the hydraulic pressure sources of the hydraulic cylinders 11, 12 and 20, 21 are connected.
