Stop device for downward belt conveyor with large inclination-angle

The utility model discloses a stop device for a downward belt conveyor with a large inclination-angle, which comprises upright columns, a baffle and a limited rod, wherein the left and the right upright columns are arranged in parallel on the two sides of a conveyer frame; the lower ends of the upright columns are connected with a baseplate tightly; the upper ends of the upright columns are equipped with pin holes; a hanging arm is arranged on the baffle, and is movably connected with each upright column; and the limited rod is positioned at the lower part of the hanging arm and is connected with the upright columns tightly. After the structure is adopted, the baffle is buckled at the upper part of a material under the gravity action during the operating of the conveyer, thereby stopping material blocks sliding downwardly and tumbling effectively, and ensuring the safe transportation of the downward belt conveyor at the large inclination-angle.
