[0024] Example:

[0025] Reference Figure 1-4A dredged soil improvement device for high-standard farmland includes a mobile frame 1, a drying box 2 and a conveying mixing drum 3 are respectively arranged on the top of the mobile frame 1 through a bracket, a stirring and crushing assembly is arranged in the drying box 2, a discharge pipe 301 that passes through the mobile frame 1 and extends downward is connected to the bottom of the conveying mixing drum 3, a connecting pipe 4 is arranged between the drying box 2 and the conveying mixing drum 3, a repair liquid spraying assembly is arranged on the connecting pipe 4, a baffle 5 for sealing the bottom opening of the drying box 2 is arranged on the top of the connecting pipe 4, and an electric push rod 501 is arranged between the baffle 5 and the connecting pipe 4.

[0026] Specifically, the dredged soil is placed in front of the farmland and poured into the drying box 2. The drying box 2 dries and hardens the wet dredged soil. The stirring and crushing component can stir the dredged soil in this process to speed up the drying time of the dredged soil in the drying box 2. At the same time, the stirring and crushing component crushes the dry dredged soil to increase the specific surface area of ​​the dredged soil. Then, the electric push rod 501 is controlled to work so that the electric push rod 501 drives the baffle 5 to move. The baffle 5 no longer blocks the bottom opening of the drying box 2. The crushed dredged soil enters the conveying mixing barrel 3 through the connecting pipe 4. The repair liquid spraying component sprays the repair liquid on the crushed dredged soil dust to improve the fusion degree of the repair agent and the soil. Then, the conveying mixing barrel 3 further mixes the clay mixed with the repair agent and the soil during transportation, and discharges the clay into the farmland during the movement of the mobile frame 1 to ensure the dredged soil improvement efficiency and improvement effect.
