摘要： An apparatus for controlling the posture of the work implement of a loader comprises a boom supported by a boom pivot on a mast secured to a vehicle body and movable upward and downward by a boom cylinder, first and second arms supported by an intermediate portion of the boom and pivotally movable relative to each other, a pivotal member pivoted to the boom by the boom pivot, a first connecting member operatively connecting a point on the pivotal member away from the pivoted point thereof to the first arm, a second connecting member connecting the second arm to the work implement at the forward boom end, an engaging portion for engaging the second arm with the first arm when the implement is moved by an implement cylinder in the scooping direction approximately into a specified posture, and an interlocking member operatively connecting the pivotal member to an implement control valve for the implement cylinder so that the valve is operated in the dumping direction by the movement of the pivotal member with the rise of the boom after the second arm is engaged with the first arm by the engaging portion. The implement can be maintained in the specified posture when the boom is raised, preventing earth from spilling from the implement.

摘要： PURPOSE:To raise the reliability of a loader at low cost by mechanically holding the attitude of working tool by a method in which the ascending action of a boom is fedback to the control valve of the working tool cylinder from the lifted up condition of working tool by a link mechanism. CONSTITUTION:The second arm 22 to transmit the vertical action of a working tool 9 and the first arm 21 to be coupled with the arm 22 in relatively turnable manner when the tool 9 is upwardly turned to almost lift-up attitude B are pivotally supported on the midway of the boom 7. A rocking part 28 connected through the arm 21 and a link 29 to the pivotal shaft 6 of the boom 7 is also pivotally supported. The part 28 and the rocking piece 42 for the control valve 35 of working tool are connected with an interlocking part 52. With the rise of the boom 7, the arm 21 is coupled with the arm 22, the rocking part 28 is rocked through the link 29, and the control valve 35 for working is operated to hold the lift-up attitude B of the working tool 9.
