摘　　要：针对滨海砂矿丰富的矿产资源利用问题,以跳汰设备为原型设计了一种新型的船用选矿设备。在动力及传动结构上,以液压马达代替传统的电机,并以齿轮齿条做为传动机构实现优化,使其更加贴合电气控制,更方便地实现系统的程序动作,满足对选矿设备的自动化控制。同时为了实现不同矿区不同矿含量自适应控制,从实际应用角度出发设计研制了一种符合生产应用要求的自动跳汰控制系统。以床层松散度作为控制对象,用浮标传感器对床层跳动高度进行检测,并通过PLC输出所需的跳汰周期曲线,最后根据设计的液压系统控制液压马达对选矿设备的工作参数进行控制。研究结果表明,该控制系统能够较好地实现对设备工作参数的控制,设备分选效率高,可靠性强,适用范围广。Aiming at rich mineral resources of coastal sands,a new type of marine mineral processing equipment was dessgned based on jigging equipment。In the power and transmission structures,the hydraulic motor was used to replace the traditional motor,and the rack and pinion drive mechanism was used to optimize as to make it more fitting for electrical control,more convenient to operate the system to achieve the program,and meet the automated control of processing equipment. Meanwhile,in order to achieve adaptive control of different content for different ore mining,therefore,designing auto-jigger system for beneficiation from a practical point of view to meet the requirements of production applications was imperative. Regarding loose bed degree as a control object,beating buoy bed height sensor detects and outputs required by jigging cycle curve PLC. Finally,according to the hydraulic system designed to control the operating parameters of the hydraulic motor to make processing equipment controlled. The results indicate that control system can achieve better control of operating parameters of the equipment,high efficiency,high reliability,wide application.
