Abstract
To solve the problem of the lack of theory about interaction between cutting blade and billets, and analyze the situation that the stratification of trajectory of thrown billets after whole cane was cut by chopper. The spatial posture of billets at the blade at the moment of cutting was analyzed. Through high-speed photography test, three kinds of spatial postures of billets at the blade were obtained, which were upward warping, kept feeding inclined posture and drooping, and the number of sugarcane feeding layers had no significant influence. The throwing velocity of billets was obtained by high-speed photography test tracking analysis at thrown moment, and the two-factor test analysis showed that the cutting speed of cutting blade had a significant influence on the throwing velocity, which increased with the increase of the speed of blade, and showed a strong linear correlation,but the throwing angle had no significant effect on the throwing velocity. Moreover, the linear regression analysis showed that the correlation coefficient between the blade edge linear velocity and the throwing velocity was 0.999, and the throwing velocity equivalent was 1.058. Therefore, cutting blade had a small thrust effect on billets and provided a basis for further research on the trajectory of billets.
