Abstract

A scrap magnet for an excavator is provided to remove scraps from construction waste materials effectively without replacing with an excavation bucket by integrating an excavation bucket with a casing. The invention relates to a scrap magnet for an excavator for sorting out scraps such as iron scraps contained in construction waste materials by magnetic force by coupling an excavation bucket(40) to a magnet casing(10) by joining a primary bracket(20) and a secondary bracket(30) to two ends of a magnet casing(10) having a solenoid within and coupling primary and secondary flanges(41,42) of an excavation bucket(40) to the primary bracket and the secondary bracket by bolts(50). In addition, two reinforcement brackets are installed on the circumferential surface between the primary bracket and the secondary bracket and coupled with a rib of the excavation bucket by bolts.
