Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to an additive delivery device. Background Art

[0002] Concrete additives are chemical substances added during the mixing process of concrete, accounting for less than 5% of the mass of cement, which can significantly improve the performance of concrete. These additives are usually composed of a small amount of chemical substances and can be added to concrete to improve its consolidation, durability, workability and other properties. Concrete additives are an indispensable and important component of concrete. They can significantly improve the performance of concrete and improve the quality and durability of buildings.

[0003] The existing patent announcement number CN212218864U discloses an environmentally friendly additive delivery device for a concrete mixer, which includes a motor and a guide barrel. During actual operation, the additive is pre-stored in a silo, and then a sealing plate is inserted into the opening of the silo to seal it. The rubber ring on the surface of the sealing plate is squeezed on the inner wall of the silo to play a damping role. When it is necessary to add additives to the concrete mixer, the manual valve stem is manually loosened, and the additives inside the corresponding silo fall along the discharge pipe. Multiple manual valve stems can be opened at the same time to achieve simultaneous delivery of multiple additives. When the motor is started to drive the spiral feed shaft to rotate to mix multiple additives, the mixed additives are guided downward to avoid clogging of the additives at the bottom opening of the guide barrel.

[0004] When the above device is feeding, the additive is easy to clump during the adding process, which is not conducive to the uniform mixing of the additive and concrete. The concrete needs to be continuously stirred, which wastes resources and takes time. In view of the above problems, an additive feeding device is proposed. Utility Model Content
