Claims

[Scope of utility model registration request]

The front part of the excavation device main body 1 is propelled underground in advance of the pipe body to be buried, and is angularly rotated by a rotary drive source contained in the main body 1 to excavate the ground in front of the main body 1. A cutter head 2 is provided, and the earth and sand excavated by the cutter head 2 is crushed by a gravel crushing mechanism provided between the cutter head 2 and the main body 1, and is taken into the main body 1 from the earth and sand intake port 1b, The cutter head 2 includes a gear case 5a that is rotatably supported on the rotating shaft 3, and at least one gear that is housed within the gear case 5a and meshes with a gear 6 that is fixed to the rotating shaft 3 within the gear case 5a. This excavation device for management construction is provided with a gravel crushing mechanism 5 comprising three gears 7 and a cutter blade 8a provided at the tip side of a cutter shaft 8 projecting forward from these gears 7.
