Abstract

In view of the serious vibration problem of the inclined conveyor shell of combine, the dynamic signal test and analysis system is adopted to realize the horizontal control of agricultural machinery by controlling the electromagnetic directional valve. In order to improve the bearing accuracy, this paper designs a bearing tilt detection device, when the tilt reaches its set value, it can send an alarm to start the emergency response. The real-time measurement algorithm of tractor inclination angle is tested on a three-axis multifunctional turntable. The automatic leveling system of agricultural machinery is tested on site, and the minimum inclination angle of the chute conveying various kinds of grain and oil materials is obtained. It has the characteristics of high speed, high efficiency and small resolution error. It can correct the tilt image in real time. The research is helpful to adapt to the new requirements of modern agricultural large-scale agricultural machinery or production facilities. The monitoring system has practical guiding significance in the construction process, and has promotion value.
