The invention relates to a multistage crushing and recycling machine of caked portland cement for concrete roads. The machine comprises a support baseplate, a rotating sleeve device, a crushing deviceand an unloading device; the rotating sleeve device is mounted on the left side of the support baseplate; the crushing device is mounted on the rotating sleeve device; and the unloading device is mounted on the support baseplate. The machine can solve such difficulties as low working efficiency, high labor intensity, need of manually and primarily crushing caked cement, need of manually crushingthe caked cement by many times and bad crushing effect in traditional crushing of the caked cement, can realize a function of automatically performing automatic multistage crushing on the caked cement, and has the advantages of high working efficiency, low labor intensity, automatic and primary crushing of the caked cement, automatic crushing of the caked cement by many time, good crushing effectand the like.
