Abstract (en)
An excavation device (10) comprises a pair of milling wheels (13) with a substantially horizontal axis of rotation (X), each equipped peripherally with excavation means (26), in order to define an excavation front (24) substantially parallel to the axis (X), chain-type transmission means (25) to draw in rotation the milling wheels (13), in which the transmission means (25) is driven by drive means (20) and is also provided, on the side that is external during use, with excavation means (26). The excavation means (26) comprises a plurality of excavation teeth (126) disposed on the external side of the chain-type transmission means (25) and disposed offset, with respect to each other, in a direction transverse to the longitudinal development of the transmission means (25), so that the excavation front (24) is substantially continuous and uniform.
