The utility model discloses a belt conveyer funnel with a material stop device, aiming at resolving the problem that in a sintering plant, the production is influenced as large-block sundries in materials are conveyed by a belt and then enter the next procedure. The belt conveyer funnel comprises a funnel body, wherein the upper part of the funnel body is additionally provided with the material stop device; the material stop device is formed from a bracket and a grid plate; and the grid plate is arranged on the upper surface of the bracket and at a dip angle of 10-60 degrees with the horizontal plane. By he material stop device arranged on the discharging funnel, 98% large blocks and sundries can be blocked, and the large blocks and sundries can drop to the external of the funnel along grids, thus preventing the large blocks and sundries from entering the next procedure, reducing the work intensity of workers, and stabilizing the normal operation of the sintering machine in production.
