Abstract (en)
[origin: WO2022228974A1] The invention relates to a drilling machine (10) having a bucket chassis (12) which comprises a body (16) extending along a longitudinal direction (L), a mobile element (32), a first arm (34) which is pivotable with respect to the mobile element, a second arm (36) which is pivotable with respect to the mobile element (32), the second arm having a lower end part, at least one actuator device (37) connected to the body in order to move at least the first arm (34) with respect to the body. The invention is characterized in that said drilling machine (10) has a removable milling device (100) comprising a first releasable connection device (120) for fixing the support (110) removably to the body (16), and a second releasable connection device (150) for fixing the support (110) removably to the first arm, by which means the milling device can be easily released from the chassis.
