Raw material mixing equipment and mixing method for preparing macroelement water-soluble fertilizer

The invention discloses raw material mixing equipment and a raw material mixing method for preparing a macroelement water-soluble fertilizer, and relates to the technical field of raw material mixing. The stirring device comprises a stirring rod, first connecting rods are fixedly connected to the outer surface of the stirring rod, stirring blades are fixedly connected to the ends, away from the stirring rod, of the first connecting rods, the stirring blades are arranged to be in a twisted arc shape, and second connecting rods are fixedly connected to the ends, away from the first connecting rods, of the stirring blades; one end of the second connecting rod away from the stirring blade is fixedly connected with the outer surface of the stirring rod. By arranging the twisted arc-shaped stirring blades, the stirring area is increased, the stirring effect is improved in a limited space, meanwhile, due to the fact that the stirring blades are twisted, part of raw materials can be driven to move along with the stir
