Abstract: Aiming at the problems of low output per degree and throwing distance not meeting the requirements of multifunctional forage kneading machine in practical application, the orthogonal test was carried out by selecting output per degree, average throwing distance and kneading rate as experimental indexes, and the spindle speed, moisture content and feed quantity as the factors to explore the relationship between performance and influencing factors. Range and variance analysis methods were employed to determine the primary and secondary impacts of each experimental factor on the experimental indexes and to identify the optimal parameter combinations. Additionally, multiple linear regression equations were developed based on regression analysis methods to establish relationships between the experimental indexes and experimental factors. The results show that the output per degree is the largest when the spindle speed is 2 800r/min, the moisture content is 9.75% and the feed quantity is 0.185kg/s. The average throwing distance is the longest when the spindle speed is 2 500r/min, the moisture content is 9.75% and the feed quantity is 0.185kg/s. The triturate effect is the best when the spindle speed is 2 800r/min, the moisture content is 65.58% and the feed quantity is 0.238kg/s. This study provides a reference for improving output per degree and increasing the throwing distance of multifunctional forage kneading machines.
