The invention discloses a premixed high-performance concrete mixing device, and relates to the technical field of concrete
processing. The device comprises a stirring device, a material guiding frame is fixed to the right side of the stirring device, a motor is fixed to the front face of the material guiding frame, a material mixing mechanism used for guiding aggregate is arranged in the material guiding frame, a crushing mechanism used for crushing
large aggregate is arranged at the top of the right side of the material guiding frame, and an output shaft of the motor is in transmission connection with the crushing mechanism through a belt
pulley group. Through the arrangement of a crushing roller set, aggregate is crushed by the crushing roller set, so that
large aggregate is crushed into
small aggregate, and under the action of a strip-shaped through groove, needle-sheet-shaped aggregate penetrates through the strip-shaped through groove to be screened to the bottom of the material guiding frame, so that the problems that the needle-sheet-shaped aggregate is mixed into concrete, the needle-sheet-shaped content of crushed stones is increased, and the
compressive strength value of the concrete is reduced are avoided, and the quality of
construction engineering is improved.
