Title: Belt cleaner
Inventor: DAITOKU KAZUMI
IPC: B65G45/16
Filed: 2018-10-25
Abstract: To provide a belt cleaner that solves a conventional problem where square rod-like rubber elastic bodies are largely warped in the advancing direction of the return side belt by a strongly adhered deposit and cannot go back to the original position, thereby preventing a chip from abutting the return side belt, causing failure to scrape, and due to thrust force of the return belt, gaps are made between the square rod-like rubber elastic bodies causing stripe-like scraping residue.SOLUTION: The upper parts of the square rod-like rubber elastic bodies have continuous holes in the width direction of the return side belt and a wire penetrating through the holes. The upper parts of the square rod-like rubber elastic bodies are connected by the wire, allowing the wire to function as a stopper, thereby controlling the phenomenon that a square rod-like rubber elastic body largely warps against its neighboring square rod-like rubber elastic bodies and allowing its return to the original position immediately after the adhered deposit passes through and enabling normal scraping. Furthermore, the continuous holes are provided between the chip attachment bolts, thereby avoiding reduction of rigidity of the square rod-like rubber elastic bodies due to the continuous holes.SELECTED DRAWING: Figure 1
