Abstract

In order to reduce the crushing rate of the screw conveyor device of the cutting deck of sesame combine harvester, the screw conveyor device of sesame combine harvester was designed and optimized. By analyzing the conveying process, the influence law of the diameter, rotational speed and pitch of screw conveyor on the cutting table crushing rate was derived; the EDEM simulation software was used to establish the model of sesame capsule and stalk, and the range of key parameters was determined through the one-factor pre-experiment, and the three-factor, three-level quadratic regression center was carried out by taking the diameter, rotational speed and pitch of the screw conveyor of the sesame combine harvester as the experimental factors, and the crushing rate of the sesame capsule as the indexes. Combined simulation test, established the mathematical model between the test factors and test indexes, and obtained the optimal parameters of the conveyor device, i.e., diameter 302mm, rotational speed 200r/min, and pitch 422mm.This study can provide a reference for the optimization of the parameters of the screw conveyor device of the sesame combine harvester and the reduction of the loss rate of the cutting platform.
