Claims

[Scope of utility model registration request]

As shown in the drawing, an excavation machine consisting of a plurality of frame rods 7, a frame body 20, a bottom cover 24, etc. is excavated by expanding and contracting a plurality of hydraulic cylinders 10 through a hole wall lower holder 8 and a shaft 11. In the earth and sand storage structure, from the vertical movement trajectory of the slide block 13, the hole wall lot 1 is
8, the hole wall frame 22 and the hole wall rod 3 have a sandwich plate-like configuration, and the frame body scraper 16 is transmitted through the scraper rod 21 with a simple operating mechanism, and the hole wall frame 22 and the hole wall rod 3 are spread. The structure of the hole bottom expansion bucket drilling equipment is characterized by the ability to perform hole bottom expansion excavation with the cutter 9.
