由于使用半喂入式脱粒机能很好地回收作物秸秆,所以这类型式的脱粒机在市场上,很受欢迎。现有各种脱粒机普遍存在损失率大、效率低、湿脱困难及稻麦通用性差等问题。对脱粒机的脱粒质量进行因素分析,以寻求提高脱粒质量的方法,对促进粮食增产增收具有重要意义。所谓半喂入式脱粒机,就是脱粒时,作物不全部进入脱粒部件,作物的茎秆根部由手或夹持链夹住,并以一定的速度在滚筒上面的脱粒室内或滚筒下方与凹板形夸的脱粒室内平行移动。此时,滚筒上的弓齿
This type of thresher is very popular on the market due to the good recovery of crop stalks using a semi-fed thresher. The existing various thresher widespread loss rate, low efficiency, wet off difficulties and poor generality of rice and wheat and other issues. The threshing machine threshing quality factor analysis, in order to seek ways to improve threshing quality, to promote grain production and income is of great significance. The so-called semi-fed thresher is threshing, the crop does not all enter threshing parts, stems of the crop by the hand or the clamping chain grip, and at a certain speed in the drum above the threshing chamber or drum and the concave below the plate Shaping the threshing room parallel movement. At this point, the bow on the bow
