| Abstract: | Currently in the industry, artificial broccoli cutting is used for the time being. The efficiency is low, and now mechanical device is needed to solve this problem. The broccoli cutting and throwing core mechanism was put forward. The working principle of broccoli cutting and throwing head mechanism was analyzed, the kinematic model was established, the computer aided optimization software was developed and a set of structural parameters was obtained to meet the trajectory requirements. The dynamics simulation of the mechanism was carried out. The simulation trajectory was basically consistent with the theoretical optimization trajectory. The mechanism motion was stable and there was no force overload phenomenon. The design of the physical prototype was completed and the high speed photographic movement experiment was conducted. The prototype test results were basically consistent with the ideal trajectory, and the cutting tool was suitable for cutting broccoli in all sizes to meet export requirements, which verified the rationality of the design of broccoli cutting stem and throwing head mechanism. The cutting stem and throwing head tests were completed on the test bench, the success rate of cutting was 91%, success rate of throwing head was 100%, and the export requirements of broccoli small pieces on the market were met, which verified the feasibility of the broccoli cutting and throwing head mechanism. |
