PURPOSE:To make broad excavation performble, by installing a screw type excavating device in a platform so as to make it possible for roughing, while installing the said device, an excavated matter transporting device and a delivering device in a tiltable platform altogether. CONSTITUTION:A platform 6 is installed in the upper part of a crawer or a self- propelling device 2 tiltably in a direction right-angled with the traveling direction via plural hydraulic jacks being tightly attached to a crawer frame 2a. And, the platform 6 is installed free of swivel motion within a plane surface via a ring gear or a swivel mechanism being built in a base block 5 and a gear engaged with the former. Then, a screw type excavating device 9 is mounted on this platform 6 so as to make it possible for roughing with operation of a hydraulic cylinder 8. A transporting device 10 is installed in the central part of the excavating device 9, while a delivering device 15 consisting of a conveyor 15A supported turnably on the platform 6 is set up beneath the position of an outlet end part 10f of the said device 10. |
