Grooving rake

The slotting rake comprises a rake rod assembly and a rake box fixed to the end of the rake rod assembly, a plurality of strip-shaped leakage holes are evenly formed in the surface of the left side of the rake box, a plurality of rectangular leakage holes are evenly formed in the surface of the top of the rake box, and a plurality of oval leakage holes are evenly formed in the front surface and the rear surface of the rake box. The rake rod assembly comprises a base rod, a telescopic rod and a rod handle, the base rod and the rake box are welded and fixed, a telescopic groove is formed in the base rod, and one end of the telescopic rod is inserted into the telescopic groove; the rake box is arranged to be in a grid shape, so that in the follow-up slotting process, blocky anode mud can be well accumulated in the rake box, pasty anode mud leaks out through the leakage holes, the purposes and effects of slotting and cleaning are achieved, enrichment of the anode mud in an electrolytic cell is reduced, and the pr
