The invention discloses a low-resistance deep-
scarification fertilizer spreader for
saline-
alkali soil based on self-
adaptive control, and provides an innovative scheme aiming at the problems of soil hardening, non-uniform application of a modifier, low operation efficiency and the like. The whole
machine comprises a rack, a modifier box, a double-row
shovel, a multi-leaf
discharger and an
intelligent control system. A front row of shovels and a rear row of shovels are designed, a front triangular
shovel reduces
tillage resistance through wedge-shaped splitting, a rear
subsoiler cuts off soil capillary tubes, a discharging
pipe is arranged in the rear
subsoiler, and deep and accurate throwing of an improver is achieved; 2, PID parameters are optimized based on an improved
genetic algorithm, closed-
loop control and low-pass filtering
noise reduction are combined, a self-
adaptive control system is constructed, and the discharging amount and the advancing speed are dynamically matched; the soil pressing roller and the
shovel are designed cooperatively, the whole process of soil breaking, deep
scarification, agent applying and pressing is completed at a time, and efficiency is improved. Through a low-resistance structure,
intelligent control and integrated operation, the equipment breaks a hardened layer, inhibits salt from moving upwards, improves the
utilization rate of an improver, has the characteristics of high efficiency, low consumption and ecological protection, and meets the treatment requirements of
saline-
alkali soil.
