The device comprises a base and a housing. The housing is fixedly mounted on one side of the upper end of the base, and a feed port is provided at the top of the housing. A drive motor is mounted on one side of the housing, and a stirring rod is rotatably connected to one end of the drive motor. A cavity is mounted on one side of the housing near the top of the drive motor. After the concrete blocks are crushed and screened, the drive motor is started to drive a stirring rod to rotate. At the same time, the drive motor drives the four stirring rods to rotate through the shaft joints at one end of the four stirring rods and the transmission belt. The four stirring rods are interlaced to achieve a better stirring effect on the crushed concrete blocks, thereby solving the problem of insufficient stirring effect in existing concrete block recycling crushing devices.
