The 2BMFJ type no-till precision planter which applied the way of expelling straw sideways was able to integrate seedbed preparing, precision seeding, fertilization, compacting, pesticide spraying, and straws mulching equably at one operation. The planter has become an important technical mean to guarantee the combination of intensive cultivation and conversation tillage of corn, soybean and peanut. It’s necessary to design a kind of straws recovering device matching the 2BMFJ type no-till precision planter, because of the reason that crop yield and microorganism were affected by crop-residue incorporation significantly. In order to understand the law of lateral throwing of straws which was impacted by the cleaning device of the 2BMFJ type no-till precision planter, comprehensively considered with the influence of air resistance, soil interference and other uncontrollable factors on the spatial trajectory of the straws, the kinetics analysis of lateral throwing process of straws was taken, a model of straws lateral throwing kinetics with modified coefficients and a parametric equation of spatial trajectory of straw were established. A modified coefficient regression model which applied with the method of three-factor and five-level quadratic regression orthogonal center combination and a high-speed photography technology was established. The kinetics model of lateral throwing of corn straws was used to match the straws recycling device and cleaning straws device. The results of field test showed that straws recovery rate was up to 91.21%, and the uncleanness rate was 6.08%. The research result can provide reference for the design of 2BMFJ type no-till precision planter matching a kind of straws recovering device.
