The invention discloses a steering system of a four-wheel boom sprayer, which is characterized in that an angle sensor (master) and an angle sensor (slave) are respectively mounted on two sides of a front axle to detect actual turning angles of inner and outer wheels in real time; an auxiliary steering two-way hydraulic oil cylinder is installed on one side of an angle sensor (slave) on a connecting rod of a front-back steering hydraulic oil cylinder to carry out push-pull work and compensate the angle difference value of inner and outer wheels in real time, so that front and back walking wheels of the spraying machine walk according to concentric circles, the steering radius of a unit can be reduced, and the resistance of the wheels during steering walking is effectively reduced; meanwhile, crop loss caused by field operation is effectively reduced; the rotating ring with the guide wheels installed on the two sides is arranged in the rotating cavity and matched with the variable resistance strip to achieve telescopic control over the damping spring, telescopic adjustment of the damping spring is controlled according to the flowing condition of hydraulic pressure, and therefore the whole spraying machine is kept in the horizontal spraying state, and the spraying uniformity is guaranteed.
本申请公开了一种四轮喷杆喷雾机的转向系统,通过设置在前桥两侧各安装一个角度传感,分别为角度传感器(主)、角度传感器(从),实时检测内外车轮实际转弯角度,在前后转向液压油缸连杆上角度传感器(从)一侧安装一辅助转向双向液压油缸,进行推拉工作,实时补偿内外轮角度差值,使得喷雾机的前后行走轮按照同心圆行走,既能减小机组的转向半径,有效地降低了转向行走时车轮的阻力,同时也有效地减少了田间作业时造成的农作物损失;通过设置有两侧安装导轮的转环在转动腔内部,并配合变阻条实现减振弹簧的伸缩控制,根据液压的流动情况来控制减振弹簧的伸缩调节,从而使得喷雾机整体保持水平状态喷雾,保证喷雾的均匀性。
