Description

Technical Field

[0001] The utility model relates to the technical field of concrete powder feeding, in particular to a powder feeding device used in a concrete mixing station. Background Art

[0002] When mixing construction materials, a concrete mixing plant needs to use a feeding device to add powder. Since powder is prone to moisture and agglomeration during long-term storage, a crushing device is generally added at the powder feeding position to crush the agglomerated powder.

[0003] A Chinese patent discloses a powder feeding device for a concrete mixing station, with the publication number CN213732622U, comprising a feed hopper, a cover plate is provided on the top of the feed hopper, a fixing mechanism is provided on both sides of the cover plate and the feed hopper, a discharge pipe is provided at the bottom of the feed hopper, a feeding pipe is provided on both sides of the feed hopper, an electric cylinder is fixed at the center of the upper surface of the cover plate, a crushing plate is fixed at the moving end of the electric cylinder, a first fixing ring is provided horizontally inside the feed hopper and located below the feeding pipe, a second fixing ring is provided inside the first fixing ring, the first fixing ring and the second fixing ring are connected and provided together through a plurality of evenly distributed fixing rods, and a partition net is fixed between the first fixing ring, the second fixing ring and the fixing rod. The utility model can crush the agglomerated powder, and at the same time, the dredging rod can dredge the discharge pipe up and down, thereby ensuring the continuity of feeding and thus ensuring the normal operation of the concrete mixing station.

[0004] However, there are still some disadvantages: the device controls the extension of the electric cylinder to make the crushing plate crush the agglomerated powder above the partition, but the agglomerated powder may adhere to the gap of the partition after being squeezed, affecting the discharge of the device. Therefore, we propose a powder feeding device based on concrete mixing station to solve this problem. Utility Model Content
