1858. Design of a live animal vibration automatic control screening machine based on meta-component and semantic similarity principle.

A novel live animal screening machine was designed to solve the screening issue for yellow mealworm and frass in the artificial breeding production process. The control system based on semantic similarity computation, operation mode, overall structure, working principle and main structural parameters of the machine were designed and optimized in this study. Furthermore, the kinematics mathematical model of the crank-rocker of shaking and the screening mechanism was analysed. In addition, motion analysis of shaking and screening mechanism was conducted, and then the displacement, velocity and acceleration curves of pendulum rod and screening body were obtained. Finally, the structure design and motion simulation of all parts were finalized to confident with the design. The prototype performance tests of the yellow mealworm screening machine show that machine has a reasonable structure, convenient operation, good screening effect and high working efficiency. This study provides a new thought for screening yellow mealworms. [ABSTRACT FROM AUTHOR]
