摘  要：
为了给6PYL-305型剖鱼机制造一种自动喂料设备,该文设计了一种淡水鱼头尾与腹背定向装置,并以鲢鱼为定向对象,根据鲢鱼的摩擦特性,通过理论分析,分别对利用倾斜振动台面实现头尾定向和利用渐变滑道实现腹背定向过程的机理进行了探讨,并采用质量为0.75～1.0kg的新鲜鲢鱼进行了试验研究。理论分析和试验结果均表明,该定向装置可以实现鲢鱼的头尾和腹背定向。并对影响鱼体头尾定向因素:进入振动台面的体位、电动机频率、激振力和筛面角,以及影响鱼体腹背定向因素:滑道夹角、电机频率、激振力和滑道倾斜角分别进行了试验研究,得出各因素对定位时间均具有显著的影响;头尾定向的总定位率达97.53%,定向动作可在0.65～3.75s内完成;腹背定位的总定位率达97.5%,定向动作可在0.39～5.03s内完成。研究结果可为淡水鱼连续化加工中定向连续喂料设备的产品开发提供技术依据。

摘  要：
In order to manufacture an automatic directional transport feeding device for 6PYL-305-type fish splitting machine,a device to set the freshwater fishes' heads and backs in the desired direction was designed,and silver carp was taken as the research object.Based on the friction properties of silver carp,the mechanism of using the tilt vibration plate to set the freshwater fishes' heads forward and the gradient slide to set the freshwater fishes' backs up were theoretically discussed,and the experiment of directional transport for fresh silver carp of 0.75-1.0 kg was carried out.Both the theoretical analysis and experimental results showed that this device could set the freshwater fishes' heads and backs in the desired direction.The factors affecting heads forward setting of fishes such as the original orientation of the fish on the vibration plate,vibration frequency,excitation force of the motor,and inclination angle of the plate surface,and the factors affecting backs up setting of fishes including the angle of the gradient slide,vibration frequency,excitation force of the motor and the inclination angle of the plate surface were studied.The results showed that each factors had a significant impact on the directional time-consuming.The total success rate of heads forward setting of fishes was 97.53%,and setting time was within 0.65-3.75s.The success rate of backs up setting of fishes was 97.2%,and the setting time was within 0.65-3.75 s.The results can provide technology references for designing of feeding machine which can be used in continuous processing of freshwater fishes.
