The invention discloses an agricultural onboard hoisting buffering system which comprises a tractor, an onboard displayer, an intelligent armrest box controller, a hydraulic system, a large lifting arm, a hoisting arm, a steel wire rope and an angle sensor, a hydraulic oil cylinder drives the large lifting arm to rotate around a shaft, the hoisting arm and the angle sensor work in a follow-up mode, and a heavy object is hoisted through the steel wire rope. The system adopts the angle sensor to monitor the horizontal included angle of the large arm in real time, the intelligent armrest box controller compares a preset value through a negative feedback fuzzy PID algorithm to conduct dynamic adjustment, and overshoot and whole machine vibration are effectively restrained. A buffer control strategy is shown as follows: the hydraulic proportional valve is gradually opened to realize stable acceleration in the initial hoisting stage and gradually closed to finish deceleration stopping along with the heavy object approaching the preset height in the later stage, and impact and pitching vibration are remarkably reduced. And in cooperation with a height preset function of an airborne display, the whole-process operation can be completed by one key. The system is reasonable in structural design, the operation intensity of a driver is greatly reduced while the operation efficiency is improved, and the equipment reliability and the operation stability are enhanced.
