Novel vacuum hopper device applied to material pumping

The utility model discloses a novel vacuum hopper device applied to material pumping, which comprises a vacuum hopper main body with a hollow structure and a rectangular transition piece connected through a bolt and/or a welding mode, one end of the transition piece is connected with a first air cylinder through a bolt, and one end far away from the first air cylinder is connected with a second air cylinder through a connecting pipe. A first clamping buckle is fixedly arranged on the connecting pipe, the transition piece is communicated with the vacuum hopper body, second air cylinders are symmetrically connected to the two sides of the rear end of the transition piece through bolts and/or in a welding mode, and the ends of the second air cylinders are connected with a linkage plate through bolts. The upper end face of the second air cylinder is connected with a positioning plate symmetrical to the linkage plate through a bolt, the linkage plate and the positioning plate are in a concave shape, and a rotating
