The invention relates to a hole
sowing and fertilizing mechanism and a hole
sowing and fertilizing method, and belongs to the technical field of
agricultural machinery. The invention provides a technical scheme for creating a static operation window through
mechanical energy storage release. The mechanism comprises a traction device with an elastic
power storage unit, a ditching vertical shaft, a rotary type circular
ditch fertilization unit, an IMU (
inertial measurement unit) and a ground anchor braking device, wherein the ditching vertical shaft and the rotary type circular
ditch fertilization unit are coaxially nested; according to the method, the rack enters a local static state through periodic
energy storage and release of the elastic force storage unit, an annular fertilization area is formed around a seed falling point during static, central seed metering is completed, the static state is detected by the IMU to trigger cooperative action, and the static stability is enhanced through ground anchor braking. Spatial separation and annular fertilization of seeds and fertilizers are realized, the
utilization rate of the fertilizers is increased, a
tractor does not need to stop, the triggering reliability is high, the device is suitable for various hole
sowing crops such as corn, soybeans and cotton, and the replacement time is short.
