Abstract

At present, straw harvesting operation is performed according to artificial experience, and there is no scientific method to detect the feeding quantity of the mobile straw granulator. This paper designed a feeding quantity detection system based on the power of the motive power shaft of the screw conveyor of the mobile straw granulator. The detection system includes the detection device and the detection method. The detection device consists of torque sensor, rotation speed sensor and on-board industrial computer. The detection method obtains the feeding quantity with the power that can be computed according to torque and rotation speed. The detection system was evaluated on the mobile straw granulator of Liaoning Ningyue agricultural machinery company. The field experiment shows that the average error of feeding quantity detection system is 7.5%, and the detection accuracy can meet the actual needs of the field application.

Abstract in Chinese

目前,秸秆收获作业靠人工经验判断,没有科学的方法来检测移动式秸秆制粒机的喂入量,本文设计了基于移动式秸秆制粒机螺旋输送器动力轴功率的喂入量检测系统。喂入量检测系统包括喂入量检测装置和喂入量检测方法。喂入量检测装置由扭矩传感器、转速传感器、车载工控机构成;喂入量检测方法中使用功率预测秸秆喂入量,功率通过扭矩与转速间接求取;本文以辽宁宁越农机公司的移动式秸秆制粒机为试验平台对检测系统进行了验证。田间试验表明,采用喂入量检测方法的平均误差为7.5%,检测精度能够满足实际田间应用需求。
