Mechanism of loader working device tool tumbling consists of a jib (1) which is with its first rotating linkage (2) linked to the frame (3) by a lifting hydraulic motor (4). The jib (1) is via a second rotational linkage (5) connected to a toggle lever (6) which is through a third rotational linkage (7), a long draw bar (8), the fourth rotational linkage (9) and the short draw bar (10) connected to the a tool (11). The fourth rotational linkage (9) is via a support (12) and the fifth rotational linkage (13) connected to the jib (1). The toggle lever (6) is via a sixth rotational linkage (14), a tilting hydraulic motor (15) and a seventh rotational linkage (16) connected to the jib (1). The lifting hydraulic motor (4) is connected to the frame (3) through a eighth rotational linkage (17). The jib (1) is connected to the frame (3) by a ninth rotational linkage (18). |
