The difference of end angle has no noticeable effect 测试结束角不同不会产生显著影响。
Based on analysis of the forces exerted to seeds in metering device during working procedure , the theoretical calculation equations for beginning and end angles of seed cleaning in scoop metering device with declined disc were established , and the impact of construction and working parameters on seed filling and cleaning were investigated 摘要以排种器工作过程中种子的受力分析为基础,建立了排种器清种起始角和清种结束角的理论计算公式,分析了倾斜圆盘勺式精密排种器结构参数和工作参数对充种和清种性能的影响。
