Abstract

PROBLEM TO BE SOLVED: To make it possible to perform screening work for iron scraps or the like by attaching an electromagnet to the inner surface of a working bucket to be installed to a construction work machine. SOLUTION: An intermittent switch at a power supply is turned on to apply a current to an electromagnet 6 through an electric wire 6d thereby exciting the electromagnet 6. Next, a cutting blade portion 10a of a bucket 2 is dashed into a stock of waste containing an iron scrap for scooping the iron scrap, and the iron scrap is absorbed to the top of a protection plate 8 covering the electromagnet 6 by the absorbing power of the magnet 6. Next, the intermittent switch is turned off to stop a current to the electromagnet 6 thereby releasing magnetic excitation and absorption of the iron scrap. The same process is repeated several times depending upon the amount, size or the like of the iron scrap contained in the waste for screening the iron scrap. By doing this, screening work for an iron scrap or the like can be performed without changing a working bucket.

According to the working bucket with the electromagnet constructed according to the present invention, the sorting work of iron scraps or the like can be appropriately performed only by the working bucket. That is, (1) Iron scrap is attracted by the electromagnet in the bucket in the process of scooping, discharging, transporting, and the like the waste material in a state in which the electromagnet of the bucket is excited. Then, iron debris can be released by canceling the excitation of the electromagnet and removing the attraction force. Therefore, there is no need to replace buckets, lifting magnet devices, etc. on the working machine as in the prior art, and the working machine can be used effectively with versatility, and waste material processing can be performed efficiently and at low cost. it can. (2) Since the electromagnet is mounted on the cutting blade mounting portion side of the bottom plate in the bucket, waste materials and the like are scooped by the electromagnet regardless of the amount thereof, and are effectively attracted by the electromagnet. Further, the waste material is smoothly scooped into the bucket by the protective plate covering the electromagnet, and is smoothly discharged out of the bucket.
