Eccentric shaking and bait throwing system optimization and experiment of the mobile shrimp feeding machine

Abstract:

Automatic bait feeding in shrimp pond is an inexorable trend. Mobile autonomous feeding is one of the feasible technical solutions. Evenly throwing and low crushing rate are the basic requirements. To achieve these goals, optimization was conducted on the most popular throwing tray style feeding machine. The hinged four-bar linkage of the feeding system was optimally analyzed in geometry through blocking vector polygon method, and the optimal eccentricity was obtained. The motion tracks of different bending curve bait throwing trays are analyzed. The optimal curve is acquired by bait experiment data analysis. Throwing tests provided the bait density distribution data before and after device optimization. According to the t-test statistics analysis, the uniformity of bait was improved obviously, and the crushing rate was significantly reduced as well. Optimized mobile feeding machine bait throwing experiment was conducted in shrimp pond. Results show the leakage quantity and bait crushing rate were dramatically decreased and the bait throwing homogeneity was improved, which set solid basis for the wide application of the mobile feeding machine.
