The utility model belongs to the technical field of dredging devices, and provides an anti-blocking drag suction dredger mud pipe with a front crushing structure, which comprises a shell, a connecting frame is rotatably mounted on the shell, a mud suction pipe is arranged on the shell and is communicated with a cavity of the shell, and rake teeth and an anti-turning plate are fixedly mounted at two ends of the shell respectively. A rotating plate is rotationally installed in the shell, and multiple sets of lower pressing strips distributed in a linear array mode are fixedly installed on the side, away from the shell, of the rotating plate. The utility model discloses a sand crushing device, and aims to solve the technical problem that in the prior art, hard objects such as stones and the like in sand cannot be removed, so that a crushing part is damaged due to impact between the crushing part and the hard objects such as the stones and the like. Therefore, large objects such as gravels can be moved out of the
