Abstract

Combining with the plot breeding wheat ear to analysis of its fracture morphology, by changing the stretching velocity (3 and 5 mm/min) and the stretching angle (60° and 90°), the mechanical connection forces of plot breeding wheat ear was tested under 7 kinds of moisture content, the regression model between moisture content and connecting force was established based on the test results using EXCEL. The experimental results showed that, the tensile speed had little impact on tensile ability for breeding wheat ear within the range test, but the clamping angle had significant effects. The research results could provide the reference basis for selection and optimization design parameters of the threshing device.

Keywords:
