Title:
CONTINUOUS UNLOADER USING BUCKET ELEVATOR
Document Type and Number:
Japanese Patent JP3411738
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a bottom digging device from bending and to protect a bucket elevator by mounting an extendable damping device having a detecting function at the tip of a front link and by fixing the damping detecting device on the bottom digging frame with pins.
SOLUTION: A rear link 8 and a front link 9 bending forward are mounted with pins at the bottom of a vertical frame 6 of a bucket elevator and a cylinder 10 is mounted with pins between a bending part of the rear link 8 and the vertical frame 6. A digging frame 11 houses a horizontal cylinder comprising double inner/outer cylinders extended thereby. The rear link 8 is connected to one end of the digging frame 11 with a pin and the front link 9 is connected to the center of outer cylinder of the digging frame 11 via a pushing-up force damping detecting device 12. When the pushing-up force is small, it is absorbed by the pushing-up force damping detecting device 12 and when it is large, the bucket elevator is retracted.
