A construction waste recycled concrete processing device and method

Abstract

The invention relates to the technical field of concrete processing, and in particular to a construction waste recycled concrete processing equipment and a method thereof. Crushing blades on two groups of crushing rollers move alternately to crush the construction waste. When the crushing strength needs to be changed, air is inflated into the main air pipe to increase the pressure in the main air pipe as a whole. A pressure gauge detects the pressure in the main air pipe. When the pressure in the main air pipe increases, each part is connected to each other, and the pressure between each part is equal. When the pressure increases and the middle pressure is greater than the elastic force of the compression spring, the rack moves toward the direction of the spring cavity, thereby engaging the transmission regulating gear to rotate, and the regulating gear drives the threaded rod to rotate. The threaded rod rotates and drives the crushing blades to extend outward, thereby making the crushing finer. On the contrary, the pressure is released, thereby making the crushing blades retract, making the construction waste crushed coarser. The invention can adapt to different requirements and avoid the problem that concrete cannot enter between the crushing rollers, thereby improving the crushing effect.
