摘　　要：目前,小区育种播种机定长获取方式主要通过人工测量,效率低且作业强度大,严重制约了小区育种机械的快速发展。为此,设计了一种钢索复卷测程装置,采用自动收放式测程,通过探测装置检测钢索固定的钢制或橡胶等材质球体获取小区育种播种机区间位置数据信号。为了确定不同前进速度下钢索复卷测程装置连续工作的合理参数范围,通过样机试验对装置进行参数优化。试验结果表明:往复导线轮V型角度在10°~20°之间,往复丝杠长度在400~450mm之间,装置运行稳定且无钢索缠绕和收排线集中等问题,带有触点式的行程开关的信号传输和控制运行稳定可靠,达到了育种播种机测程的要求。At present,the fixed length acquisition method of community breeding planter is mainly through manual measurement,and the low efficiency of manual range measurement and high operation intensity seriously restrict the rapid development of community breeding machinery.In view of the above problems,a steel cable rewinding range measuring device is designed.The device adopts automatic retracting range measuring,and the detection device detects the steel or rubber spheres fixed by the steel cable to obtain the interval position data signal of the community breeding seeder.In order to determine the reasonable parameter range of the continuous operation of the cable rewinding range measuring device at different forward speeds,the parameters of the device are optimized through prototype tests.The test results show that the V-shaped angle of the reciprocating lead wheel is between 10°and 20°,the length of the reciprocating lead screw is between 400-450mm,the device operates stably and has no problems such as wire rope winding and centralized collection and arrangement of wires.The signal transmission and control operation of the contact travel switch are stable and reliable,which meets the range requirements of the breeding seeder.
