摘要： In order to further improve the crushing quality of corn stalks, this research designs a corn stalk crushing and throwing device. First, it introduced the overall structure and working principle, and analyzed the crushing mechanism of corn stalks to obtain the main factors affecting its crushing performance. Then, the crushing blade in the crushing chamber was designed to determine that the number of crushing blades was 10. Kinematics and dynamic balance analysis, and the establishment of a mathematical model, the speed range of the crushing cutter shaft was 530 similar to 900 r/min. On this basis, the ADAMS motion simulation software was used to measure the change curves of the restraint force, runout, and acceleration of the shaft end with different speeds of the crushing cutter shaft. The simulation analysis finally determined that when the speed of the crushing knife shaft was 700 r/min, and the working performance of the device was better and meets the requirements of dynamic balance. Finally, the verification test was carried out, and the result shows: when the speed of the crushing knife shaft was 700 r/min, the qualified rate of corn stalk crushing length was 93.65%. Compared with the original silage corn crushing and throwing device, the performance had increased by 4.78%. It meets the standard of corn stalk crushing operation, which can provide a theoretical basis and scientific basis for the design and optimization of corn stalk crushing and returning equipment.
