摘要
为了便于捕捞后的鱼类后续加工,需要对其大小进行自动分级,分级是加工前处理的重要环节之一。基于鱼类体维特征存在一定比例关系,对鱼类分级原理进行了分析,初步确定鱼的分级间距。针对不同鱼类的体维特征参数存在差异,设计了一种分级间距可以调节的机械式自动分级装置,对分级装置结构组成及工作原理进行了叙述。根据分级装置结构性能,以分级辊不同倾角和转速对该分级装置进行了实验研究。结果表明该装置分级方法可靠,最大混级率为5.83%,处理能力为2.1t/h,能够达到设计要求。
In order to facilitate fish processing after harvest,automatic grading on its size is necessary,which is an important part of the pre-processing.Based on a certain proportion of the dimensional characteristics of the fish body,analyzing the grading principle of the fish,we initially identified the space of fish grading device.According to dimensional characteristics of different fish body parameters,an automatically grading device in wihich space can be adjusted was designed,and the composition structure and working principle of grading device were described.On the basis of device structural function,experiments have been done to this grading device at different inclinations and speeds of grading rollers.The result shows that the device grading method is reliable,with the largest mixed-level rate of 5.83%,and with a processing capacity of 2.1 t/ h,can meet the design requirements.
