Optimization and Test of Structural Parameters of Flat Hob Chopper

In order to reduce the chopping power consumption of a flat hob chopper (referred herein as chopper) on premise ensuring effect chopper, mathematical model optimal design is established in this paper with minimum objective. With help MATLAB software, solved. The curves each point blade edge line before and after optimization structural parameters are generated. results indicate that when coordinate value A Z axis 0.7 m; included angle between bottom surface cutter roll 6°. When radius 0.11 m, can obtain theoretical power. analysis result curve parameter reduced by about 25.50% compared optimization. choppers was trial manufactured sequentially mounted performance test bench system forage ramie harvester. show standard-length rate stalk chopped were 92.96% 92.84%, respectively, which extremely close other, indicating has no influence chopper. 22.25% optimization, software (25.50%), accurate reliable. This study provide foundation an method for lowering
