摘要:
Articulated operating arm comprising at least a first articulation (1) and a second articulation (2), which first articulation is connected for pivoting around a first axis (A1) to the second articulation (2), wherein a control member (6) is operative for the purpose of moving the second articulation (2) relative to the first articulation (1), which control member has a first end (601) coupled to a coupling structure (210) which is configured to connect this first end for pivoting around a second axis (A2) to the second articulation (2), which second axis (A2) is parallel to the first axis (A1), wherein the second articulation comprises an elongate structure (220) and a wing (230); which elongate structure has a first end (221) for connection to the first articulation, a second end (222) and a side wall (223) between the first and the second end; which wing is attached to the elongate structure; wherein the coupling structure (210) has a first end (212) which is supported at the side wall and a second end (211) which is supported by the wing (230).

An operative arm (1) of an earth moving machine, in particular of an excavator, has a bucket (4), which is rotatable about an axis (8) under the action of a jack (10). Between the rod (12) of the jack (10) and the bucket (4), a transmission (11) is interposed provided with a first and with a second lever (18, 19), which are mutually hinged about an intermediate axis (23) parallel to the axis (8) of rotation of the bucket (4). The first and second lever (18, 19) have respective mutually opposite ends (24, 25), hinged to the rod (12) of the jack (10) and, respectively, to the bucket (4). The transmission (11) is further provided with a lever with adjustable length (30) enabling to vary the torque transmitted by the jack (10) to the bucket (4) and hinged about the aforesaid intermediate axis (23) and the axis (8) of rotation of the bucket (4).
摘要:
The invention relates to a sectional boom arm (1) for excavators, which is used for moving the tools (19) thereof. The aim of the invention is to embody the joint (8) of said boom arm (1), which connects the top part (9) to the bottom part (7) thereof, and said parts in such a way that a sufficiently large angle of movement is provided between both boom parts while the boom arm (1) has a sufficient range and large forces can be transmitted in said area between the bottom boom part (7) and the top boom part (9) in spite of a cost-saving design. Said aim is achieved by embodying the bottom boom part (7) in a rigid manner also at the upper end thereof while the bottom boom part (7) is inserted into top boom part (9) from below by means of said upper end. In order to be able do so, the top boom part (9) is provided with a fork (10), at least in the area of the joint (8), said fork (10) being open towards the bottom and accommodating the upper end of the bottom boom part (7).
