[0005] Furthermore, a check valve is installed in the water inlet pipe.

[0006] Furthermore, adjacent water inlet through holes are arranged in a staggered manner.

[0007] Furthermore, external threads are provided at both ends of the buoy, and the sealing end cover and the water inlet end cover are threadedly connected to the buoy.

[0008] Furthermore, the filter mesh is bound to the buoy by steel wire.

[0009] Furthermore, a plurality of studs are installed on the buoy along the length direction, and a plurality of mounting holes matching the studs are opened at both ends of the filter mesh, and the studs are inserted into the mounting holes.

[0010] Furthermore, a pressure cap is screwed onto the stud, and the pressure cap presses the filter mesh onto the float.

[0011] The beneficial effects of the utility model are as follows: the utility model designs a buoy filter assembly in front of the pump of the mobile Yellow River direct filtration water and fertilizer integrated irrigation equipment, which can filter out a large amount of silt in the Yellow River water, thereby ensuring the normal use of the centrifugal pump, reducing the operating failures of the centrifugal pump, reducing the frequency of maintenance, and improving the continuity and stability of the Yellow River water irrigation. It is worthy of large-scale promotion and use. Description of the drawings:
