Document Type and Number:
Japanese Patent JP3223481
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable vertical move of a leader for a shaking machine and tilting of it in any direction by improving techniques to support the leader through an arm by a base device (such as a shovel car).
SOLUTION: In a supporting/driving mechanism A for a leader 10, the leader 10 is supported by an arm 9 at an upper position α, and tilt cylinders 14L, 14R are installed at a lower position β. The tilt cylinder 14L on the left, and the tilt cylinder 14R on the right are disposed as a pair in a truncated chevron shape. As both the tilt cylinders on the left and right 14L, 14R are simultaneously expanded/contracted, the installation position β to the leader 10 is moved in a direction of an arrow (e). As one of the tilt cylinders 14L, 14R is elongated, while the other is contracted, the installation position β is moved in a direction of an arrow (f) to tilt the leader 10.
