Filtering and diluting device for agricultural bacteriophage

The agricultural bacteriophage filtering and diluting device comprises a diluting box with an opening in the upper end, a filter screen is installed on the diluting box in a threaded mode, a baffle plate is fixedly installed in the diluting box, a net cylinder is installed on the diluting box through a rotating structure, a cavity is formed in the net cylinder, and the upper end of the diluting box is provided with a filter screen. A plurality of mesh holes communicated with the cavity are formed in the mesh cylinder, a plurality of mounting rods are fixedly mounted on the mesh cylinder, and an arc-shaped seat is fixedly mounted at one end of each mounting rod. The device has the advantages that liquid in the dilution tank can be more sufficiently and uniformly mixed through cooperative use of the rotatable arc-shaped seat, meanwhile, when the arc-shaped seat rotates, fan blades can be driven to rotate through cooperative use of a gear and a gear ring, and the dilution effect can be further improved through r
