Device for feeding and conveying bulk materials

Abstract

The utility model relates to a device for feeding and conveying bulk materials, comprising a feed hopper (1) formed by four walls (2, 3, 4, and 5)-of which three walls (2, 3, and 4) are inclined relative to the horizontal plane and the fourth wall (5) is vertical-and a screw conveyor (7) located in the lower discharge zone of the feed hopper (1). The inclined walls (2, 3, and 4) are arranged at different angles relative to the horizontal plane. Vibration means (6) are mounted on the outer surfaces of two adjacent inclined longitudinal walls (2 and 3). The vibration means (6) facilitate the movement of the bulk material toward the lower part of the feed hopper (1) and its delivery to the screw conveyor (7), thereby reducing the likelihood of arching, void formation, and stagnant zones, and ensuring a more uniform material feed. The utility model is applicable for feeding and conveying powdery, granular, moist, abrasive, and poor-flowing bulk materials.
