风筛清选机是风选与筛选组合清选作业的种子加工机具,在机器进料端和尾端的两个风选管道中,种子物料中的颖壳、碎茎叶、空秕粒、尘土等轻杂质被清除,但大量杂质是靠筛选,即利用合适的筛片,按种子物料的宽、厚等尺寸分离。因此,应根据种子的形状选择筛片的筛孔形状和尺寸。 1.长形种子种子的外形尺寸通常用长、宽、厚来表示,宽度、厚度两者差别不大,而与长度差别较大,视为长形种子的如稻麦类种子。清选长形种子,一般选择长孔筛为上页,并依据种子的厚度选择筛孔尺寸(孔宽),长孔筛孔长约20毫米,对种子的长度没
Wind screening machine is a combination of wind selection and screening operations of seed processing equipment in the feed end of the machine and the end of the two wind election pipeline, the seed material in the glume shell, broken stems and leaves, empty tablets, dust Light impurities such as impurities are removed, but a large number of impurities by screening, that is, the use of appropriate sieve, according to the seed material width, thickness and other dimensions of separation. Therefore, the shape and size of sieve sieve should be selected according to the shape of the seed. 1. The shape of the seed is usually long, wide and thick. The width and thickness of the seed are not much different from those of the seed, but different from the length of the seed. Clear long seeds, the general choice of long hole sieve for the previous page, and according to the thickness of the sieve to select the sieve size (hole width), long hole sieve about 20 mm long, the length of the seed did not
