Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a high-efficiency concrete mixer. Background Art

[0002] Currently, a concrete mixer is a machine that is used to mix and stir cement, sand and gravel aggregates and water into a concrete mixture.

[0003] The prior art discloses a high-efficiency concrete mixer with an authorization announcement number of CN203854100U. The patent provides a high-efficiency concrete mixer, including a feed port, a tank body, a discharge port, and a motor above the tank body connected to a stirring paddle inside the tank body through a connecting rod. The innovation of this mixer is that an ultrasonic oscillation device is arranged on the connecting rod, including an oscillation generating device outside the tank body and an oscillation transmitting device inside the tank body. The ultrasonic oscillation device is used to break up sand and gravel aggregates in the concrete. This method is more efficient than the traditional mixing method, and it has lower requirements on the materials used. It can speed up the mixing rate and effect while reducing production costs. This new type of concrete mixer uses ultrasonic vibration to destroy the sand and gravel aggregates in the concrete, thereby making the concrete more uniform and improving the quality and strength of the concrete.
