Design and Simulation Analysis of Mechanical Picking Comb Teeth of Artificial Finger Marigold Flowers

As the key component of mechanical picking device of marigold flower, the structure, size, strength and motion of comb are closely related to the reliability and the rate of picking. In this paper, a mechanical comb for marigold based on bionic finger is designed, and the parameters of structure, row, spacing and outside diameter are designed respectively. Then, the three-dimensional model is established with ANSYS/LS-dyna platform, and the design strength of the comb-type picking mechanism is checked. The results show that the maximum deformation of the comb with 2.3802mm occurs near the top of the tooth during the picking process, which is small and meets the design strength requirements. Finally, the picking process of the comb-type picking mechanism is simulated and the result shows that when the operating speed v is set to 3.0km/h and w is set to 30r/min, the picking effect is good. The above research provides a theoretical reference for the mechanical picking of marigold.
