This invention relates to the field of
agricultural machinery technology, specifically disclosing a phase-angle adjustable seed-
fertilizer separation precision
sowing machine and method. The
machine includes a
machine frame, a
sowing device, a fertilizing device, a furrowing device, and a
phase angle adjustment device mounted on the machine frame. The
phase angle adjustment device consists of an adjustable wheel and a fixed wheel coaxially arranged, wherein the adjustable wheel is connected to the
drive shaft of the fertilizing device, and the fixed wheel is fixed relative to the machine frame. By manually adjusting the circumferential angle of the adjustable wheel relative to the fixed wheel, the
initial phase of the fertilizing device's
drive shaft can be changed, thereby precisely controlling the timing
delay of the fertilizing action relative to the
sowing action. This invention precisely controls the timing of fertilization and sowing through the
phase angle adjustment device, combined with an adjustable spatial
layout, achieving precise separation of seed and
fertilizer in both time and space. This design is compact, easy to adjust, and places
fertilizer in the root-dominant growth zone, significantly improving utilization.
