The device for mixing and compacting tidal flat sand as claimed in claim 1, characterized in that: The installation arm (1) is provided with two mixing mechanisms (2), the two mixing mechanisms (2) are arranged at intervals along the installation arm (1), and the two mixing mechanisms (2) can move in a direction perpendicular to the installation arm (1).

8. The device for mixing and compacting mud and sand on tidal flats as claimed in claim 7, characterized in that: The mixing mechanism (2) is connected to the mounting arm (1) via a horizontal moving assembly (4), and the horizontal moving assembly (4) comprises: A horizontal outer rail truss (41) disposed on the mounting arm (1); a horizontal inner rail truss (42) which is slidably disposed in the horizontal outer rail truss (41) and can extend out of the mounting arm (1), the horizontal inner rail truss (42) being connected to the mixing mechanism (2); A horizontal driving unit (43) is used for driving the horizontal inner rail truss (42) to slide inside the horizontal outer rail truss (41).

9. The device for mixing and compacting mud and sand on tidal flats as claimed in claim 1, characterized in that: The rolling mechanism (3) comprises: A mounting frame (31) connected to the mounting arm (1); The roller (32) is rotatably connected to the mounting frame (31) and is used for rolling the mixed mud and sand.

10. The device for mixing and compacting mud and sand on tidal flats as claimed in claim 9, characterized in that: The roller (32) comprises an inner roller (321) and outer rollers (322) arranged at both ends of the inner roller (321); the inner roller (321) partially extends into the outer roller (322); the mounting frame (31) comprises a telescopic frame (311) and a connecting frame (312); the telescopic frame (311) is rotatably connected to the roller (32), comprises a double-headed driving rod (3113), a roller outer rail (3111), and roller inner rails (3112) arranged at both ends of the roller outer rail (3111); the roller inner rail (3112) partially extends into the roller outer rail (3111) and moves horizontally synchronously with the outer roller (322); the double-headed driving rod (3113) is used to drive the roller inner rail (3112) to move away from or towards each other; and the connecting frame (312) is used to connect the mounting arm (1).
