Mechanical excavating shovel for dredgers - has fast acting pivot moving to dumping position for ejecting spoil

摘要

The mechanical excavating shovel for dredgers can pivot in its working or dumping position using a hydraulic cylinder. The shovel (1) is joined to the arm of the machine (10) and the hydraulic jack (9) by the two arms (3, 8) of the bridle junction. Movement of the jack (9) upon the arm (3) moves the friction roller at the end of the arm along the ejector (2). The ejector is curved at one end (5) so that the articulated turner (4) turns the bucket with greater movement than that of the jack.
