| Abstract: | Based on the harvest mode and flax characteristics in northwest China, a full feed flax threshing and cleaning machine was developed. The threshing device adopted the threshing drum consisting of corrugated rod and cutter teeth, and grid concave, while the cleaning device adopted the combination mode of vibrating screen and suction fan. The complex materials were threshed and cleaned through screening and air separation and screening. The biological characteristics of flax were measured, and the key component parameters of the full feed flax threshing and cleaning machine were determined according to the measured data, and were numerically simulated by flow field analysis. The results of the prototype test showed that the removal rate of the working prototype was 97.27%, the impurity content was 2.74%, the crushing rate was 1.86%, and the loss rate was 3.25%, which met the requirements of the operation performance standard. |
