| 摘 要： | 施肥机肥量控制系统是根据预先设定的程序控制肥料施撒装置的开度或转速,最终控制实际的施肥量,使其不受作业速度以及地形等的影响,满足施肥的农艺要求。本文通过对液压系统控制、直流电机控制和步进电机控制三种肥量控制系统进行比较,液压系统控制成本低,更利于普及和应用,适合在实际中推广应用。

| Abstract: | The fertilizer amount control system of fertilizer machine is based on the fertilizer application device to control the pre- set program of the speed, amount of fertilizer and ultimately control actual use, so it is not affected by the operation speed and terrain, meeting the agronomic requirements of fertilization. Through the comparison of three kinds of fertilizer amount control systems, the hydraulic control system, DC motor and stepper motor control, it concludes that the hydraulic control system is favorable and suitable for popularization and application in practice with low cost. |
