利用籽粒在旋转锥形筛内运动产生的惯力作用可以把大、小不同的籽粒分开，以达到清选种子的目的。锥形筛筛选的效果受到多种因素的影响，选择适当的筛子结构参数和运动参数，可以获得良好的筛选质量，采用锥形筛筛选，可以降低工作噪声，简化机器结构，提高机器的使用可靠性 The use of the role of the inertia force generated by the movement of the grain in the rotating conical sieve can separate the large and small different grains so as to achieve the purpose of clearing seeds. Cone sieve screening effect is affected by many factors, select the appropriate sieve structure parameters and movement parameters, you can get a good screening quality, the use of cone sieve screening, can reduce the working noise, simplify the machine structure and improve the reliability of the machine Sex
