When the rotating rod 6 rotates, it drives the shower head 10 to rotate, so that The scraper 8 is used to clean the concrete on the inner wall of the mixing barrel 3, which can not only reduce dust on the concrete, but also improve the mixing efficiency. When the concrete is discharged, the bagged concrete is placed on the placement inclined plate 207 in the discharge box 201, and the servo motor 203 is started to drive the blade 206 on the threaded rod 205 to slide, and the blade 206 is used to cut the cloth bag on the placement inclined plate 207, so that the concrete flows into the mixing barrel 3 through the discharge port 209. This can not only reduce people's workload, but also reduce the generation of dust, thereby protecting people's health.
