虾塘饲料投喂自动化是必然趋势,移动式自主投喂是可行技术方案之一,抛料的均匀性和低破碎率是其基本要求。为实现这一目标,对应用最为广泛的抛盘式投饵系统机构进行了优化。通过封闭向量多边形法对投饵机偏心抖料系统铰链四连杆机构进行几何分析,获得最优偏心距;对不同折弯角度抛料盘进行运动仿真,通过抛料轨迹及数据验证分析,获得了抛料盘最优折弯角度,通过抛料试验获得装置优化前后的饲料分布密度,数据统计学t检验结果表明优化后饲料抛洒均匀性明显改善,破碎率有显著降低。对优化后的整机在虾塘进行了现场抛洒试验,结果表明与优化前相比能有效减少漏料量,降低饲料破碎率,提高饲料抛洒均匀程度,为移动式虾塘投饵装置推广应用打下了良好的基础。
Shrimp pond feeding automation is an inevitable trend, mobile feeding is one of the viable technical solutions, throwing material uniformity and low fragmentation rate is its basic requirements. To achieve this goal, the most widely used selling-style bait system has been optimized. By means of closed-vector polygon method, the geometric analysis of the four-bar hinge mechanism with eccentric jitter of the bait machine was carried out to obtain the optimal eccentricity. The motion simulation of the disc with different bending angles was carried out. Through the trajectory and data validation analysis, The optimal bending angle of the tray was obtained. The feed distribution density before and after the device optimization was obtained by the throwing test. The statistical results of the t test showed that the uniformity of the feed distribution after the optimization was significantly improved and the breaking rate was significantly reduced. The optimized machine was shrimp ponds in the field of sprinkling test results show that compared with the pre-optimization can effectively reduce the amount of leakage, reduce the rate of feed broken, improve the uniformity of feed sprinkling, mobile bait for the promotion and application of equipment Laid a good foundation.
