Background technique

my country is rich in freshwater fish resources, and freshwater fish accounts for a considerable proportion of freshwater products. The processing of freshwater fish is the key to promoting the development of aquatic product processing industry. The mechanized processing of freshwater fish is generally divided into pre-processing and post-processing. The pre-processing process is the key and difficult point of mechanized processing, while the cleaning, grading, and arrangement in the pre-processing process are auxiliary processes to prepare for the post-processing. , To form a fully automated processing line, auxiliary processes are indispensable. Arranging the fish body and discriminating the head and tail is an important step for the fish body deheading process. Whether the fish body can be processed quickly and reliably is directly related to the degree of automation of the fish deheading process and whether the fish body can be accurately deheaded.

In terms of sorting and sorting, at present, artificial feeding is generally used in China to carry out manual scattered feeding, which is labor-intensive, low-efficiency and high-cost;

In terms of automatic orientation discrimination, Xu Songbo and Xu Xueyuan from Zhejiang Fisheries Institute designed related devices to study the head and tail orientation of fish. They designed a fish head and fish tail judgment device by using the different bending stiffness of fish head and tail (Xu Songbo, Xu Xueyuan). .Feasibility analysis of the design of fish body directional conveying device[J].Journal of Zhejiang Fisheries Institute,1990,9(02):131-134.); Gao Xingxing and Tan Hequn of Huazhong Agricultural University School of Engineering found that the use of inclined vibration The table can realize the head and tail orientation of fish. They designed a head and tail orientation device for freshwater fish (Gao Xingxing, Tan Hequn. Design and experiment of head-tail and ventral-back orientation device for freshwater fish [J]. Chinese Journal of Agricultural Engineering, 2011, 27( 05):342-347.), which is greatly affected by the inclination of the positioning table, the eccentricity of the vibration motor, the excitation frequency and other parameters, the parameter adjustment steps are cumbersome, the optimal parameters of the equipment are difficult to control, and the precise orientation of a single fish is effective. Not very significant; Liu Wei conducted a dynamic analysis on the two forms of uniaxial circular vibration and biaxial reciprocating vibration, and trial-produced uniaxial circular vibration equipment and biaxial reciprocating vibration equipment for fish head and tail orientation and ventral dorsal Orientation experiment (Liu Wei. Research on the orientation mechanism of the head, tail and ventral dorsum of freshwater fish and equipment development [D]. Huazhong Agricultural University, 2013.). However, the above devices all use the means of combining machinery with the physical characteristics of the fish body to orient the head and tail of the fish body by means of vibration, and all have the disadvantage of low accuracy of head and tail orientation.
