APPARATUS FOR SIFTING OUT EARTH AND SAND

摘要

PROBLEM TO BE SOLVED: To make an apparatus light and simple, to prevent the sticking of earth and sand and to materialize the reduction of troubles, the abrasion of a back hoe, and the fatigue of an operator and the improvement and stability of work efficiency by vibrating a sifting-out apparatus body having a scraping blade part by a vibrator. ;SOLUTION: A sifting-out apparatus body 2 comprises an upper surface frame part 2A, right and left side parts 2B, 2B, a bottom surface part, an upper surface lattice part 2D, and front and rear horizontal frame members 2E, 2E. A scraping blade part comprises a rear level, parallel front levers, blade parts which are installed parallel in the upper part of a front lever part and protruded upward, and inclined plate parts which are installed parallel toward diagonally backward in the lower part of the front lever part. A lattice is formed by assembling rods vertically/ horizontally on the side and spread over a whole side frame, and each and sand fall from the lattice. A vibrator part 3 is fitted to the middle position of the upper surface of the rear horizontal frame member 2E and vibrates the sifting-out apparatus body 2. in this way, the simplification and weight reduction of an apparatus are materialized, the sticking of earth and sand is reduced, and the abrasion of a back hoe and the fatigue of an operator can be reduced.;COPYRIGHT: (C)2000,JPO
