Adjustable fertilizer applicator and method for evenly tillaging maize

Abstract

The invention discloses an adjustable fertilizer applicator for evenly tillaging maize. The adjustable fertilizer applicator comprises a frame, wherein a furrow opener is arranged at the front end ofthe frame, an earth roller is arranged at the back end of the frame, and a fertilizer tank and a cylinder are arranged in the middle of the frame. A bracket is arranged at the terminal of the piston rod of the cylinder. A rotating shaft is arranged on the bracket. An axial blind hole is arranged in the rotating shaft, and multiple fertilizing tubes are fixed on the rotating shaft. The fertilizingtubes are communicated with the blind hole. A chute is arranged on the open end of the blind hole. A flexible hose is arranged on the bottom of the fertilizer tank. A slip ring is arranged at the terminal of the flexible hose and slidably interlinked within the chute. A compressed air pipe is arranged on the side wall of the fertilizer tank. A containing part is arranged at the terminal of each fertilizing tube. An impeller is connected with the containing part by shafts. Multiple vanes are arranged on the impeller. A cavity is arranged in each vane. An attached vane is arranged in the cavityand the attached vane is fixed in the cavity by a positioning bolt. The adjustable fertilizer applicator improves the deficiency of the prior art and improves the effect of topdressing maize.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn equal tillage adjustable topdressing machine and a use method thereof. Background technique [0002] When topdressing corn plants, topdressing with nitrogen and potassium fertilizers is required. In traditional production, the base fertilizer is bombarded, or the base fertilizer is used mechanically + artificial topdressing in the small horn or big horn mouth period. When the rain is relatively heavy, the soil texture is sandy, and the phenomenon of defertilization usually occurs in the later stage of corn growth; the method of mechanically using base fertilizer + manual topdressing in the small horn or big horn mouth period is currently used by farmers to grow corn for sale When the price and labor cost are out of proportion, the cost of manual fertilization is too high. Contents of the invention [0003] The technical problem to be solved by the presen...
