Study on the Compressive Mechanical Properties of Greenfeed Sweet Sorghum

The testing of sweet sorghum performance has always become a difficult problem for researchers. The physical and mechanical properties of the crop directly affect the cutting effect, power consumption and operation characteristics of the bundling harvester mechanical. This paper makes use of intelligent detection system, sampling site and loading speed influencing factors of compressive strength for the target rotation orthogonal design test, which analysed the three factors on no section and section the influence law of sweet sorghum straw compression strength. The detection system has good stability and repeatability. The experimental analysis shows that the moisture content than the sampling site is significantly affected by the compressive strength of the no section sweet sorghum stalk. The compressive strength of the section straw with the change of the sampling site and the increase of moisture content of sweet sorghum straw showed decrease the trend after the first increase. The study on the compressive mechanical properties of sweet sorghum straw can provide theoretical reference for the design of sweet sorghum harvester adjusting material device and bundling machine.
