Abstract: In order to reduce the breakage and breakage of industrial hemp stalks during the mechanized harvesting of industrial hemp, ANSYS software and SolidWorks software were used to establish the flexible body and conveying mechanism model of industrial hemp stalks, and then imported into Adams software to establish the industrial hemp stalktransporting mechanism Rigidflexible coupling model, using the maximum collision contact force as an index, using the orthogonal test method to conduct simulation tests, according to the test results to analyze the position of the lower horizontal conveying chain, the position of the upper compression spring, the position of the upper horizontal conveying chain, and the change of conveying speed on the stalk The significance and law of the influence of the maximum collision contact force of the conveying mechanism, as well as the optimal combination of operating parameters. The results show that the position of the lower horizontal conveyor chain has a very significant effect on the maximum collision contact force (P<0.01), and the order of significance from large to small is the position of the lower horizontal conveyor chain, the position of the upper compression spring, the conveying speed, and the position of the upper horizontal conveyor chain, The position of the upper horizontal conveyor chain interacts with the position of the lower horizontal conveyor chain, and the position of the lower horizontal conveyor chain interacts with the position of the upper compression spring. And when the position of the upper horizontal conveyor chain is 695 mm, the position of the lower horizontal conveyor chain is 270 mm, the position of the upper compression spring is 380 mm, and the conveying speed is 0.9 m/s, the maximum collision contact force is the smallest, which is 123 N.
