[0018] The technical scheme of the utility model is described in detail below with reference to the drawings and specific embodiments. Identical parts are denoted by identical reference numerals.

[0019] Please refer to Figures 1 to 3 The utility model discloses an eel fry fishing filter screen, including by front to rear connection gradually and diameter gradually reduced first filter screen section 10, second filter screen section 20 and third separation screen section 30.

[0020] The first filter screen section 10 includes two long fishing net pieces 11 and two short fishing net pieces. The two long sides of the two long fishing net pieces 11 are cut from front to back with a first bevel 110 and a second bevel 111, respectively. The first bevel 110 and the second bevel 111 on the same long side of the two long fishing net pieces 11 form a V-shaped structure with the middle part protruding outward in the width direction of the long fishing net piece 11. The two short fishing net pieces are both isosceles trapezoidal V-shaped structures 112. The two waist sides of the two short fishing net pieces are respectively sewn and connected with the second bevel 111 of the two long fishing net pieces 11 to form the first filter screen section 10 with the front section being symmetrically isosceles trapezoidal and the rear section being horn-shaped.

[0021] In the manufacturing process of the utility model embodiment, only the second bevel 111 of the long fishing net piece 11 and the two waist sides of the short fishing net piece are sewn together to form the first filter screen section 10 with the front section being symmetrically isosceles trapezoidal and the rear section being horn-shaped. Compared with the first filter screen section 10 of the eel fry fishing filter screen with the application number CN2022222037111, the number of sewing times is reduced by two. The reduction of sewing times effectively avoids the problem of excessive concentration of local stress of the fishing net caused by multiple sewing, makes the overall stress of the fishing net more uniform, and thus greatly improves the flatness of the fishing net, effectively ensures the uniformity and stability of the filtering process of the filter screen. At the same time, the simplification of the sewing process not only saves raw materials, but also reduces the labor cost and time cost caused by the sewing process. Moreover, due to the reduction of the number of sewing places, the probability of fishing net damage is also significantly reduced, thereby prolonging the overall service life of the filter screen and effectively improving the continuity and reliability of the fishing operation.

[0022] In the embodiment of the utility model, the second filter screen section 20 and the third separation screen section 30 are identical in structure to the second filter screen section 20 and the third separation screen section 30 of the eel fry fishing filter screen with the application number CN2022222037111, and the specific structure will not be described in detail here.

[0023] In the embodiment of the utility model, two short fishing net pieces all include two mesh parts 120 which are cut from the long fishing net piece 11 along the first inclined edge 110, the straight line parts of the two mesh parts 120 are sewn together to form the short fishing net piece, that is to say, the four mesh parts 120 in the fishing net are all derived from the cutting of the long fishing net piece 11, without additional materials, greatly improving the utilization rate of raw materials, effectively avoiding the waste of materials, at the same time, the overall structure of the fishing net is also enhanced, reducing the gap or improper matching caused by different materials, further improving the overall performance and reliability of the filter screen.

[0024] In the embodiment of the utility model, the front end of the short fishing net piece is cut to form a concave circular arc V-shaped structure, the first inclined edge 110 and the front end of the two short fishing net pieces are smoothly transitioned through the circular arc V-shaped structure, the front end of the short fishing net piece adopts this circular arc V-shaped structure, and the smooth appearance can effectively reduce the scratching and blocking of the eels. When the eels approach the filter screen, they can be guided into the net in a more gentle manner, significantly improving the netting efficiency and reducing the possibility of eels escaping due to resistance. The front edges of the two long fishing net pieces 11 and the two short fishing net pieces are additionally provided with reinforcing parts, and the reinforcing parts adopt a double-layer structure design. The purpose of setting the reinforcing part is to effectively improve the strength of the front end of the first filter screen section 10. In actual fishing operations, the front end often comes into contact with water flow, other objects and a large number of eels first. The double-layer structure reinforcing part can significantly enhance the wear resistance and impact resistance of the front end, prevent the front end from being damaged or deformed due to frequent use, and effectively ensure the normal use function and service life of the filter screen, thereby effectively reducing the maintenance and replacement cost.

[0025] In the embodiment of the utility model, the mesh aperture of the long fishing net piece 11 and the short fishing net piece is 1.3-1.8mm. The aperture can not only filter out impurities and non-target organisms with larger body size to prevent them from mixing into the net and interfering with the eel fishing operation, but also ensure that eels with smaller body size can smoothly pass into the net, thereby improving the precision and efficiency of the fishing operation, making the filter screen better meet the fishing needs of eels, and effectively improving the overall fishing quality and yield.

[0026] The above describes the technical solutions of the utility model in detail in combination with specific embodiments, and the specific embodiments are used to help understand the idea of the utility model. The deductions and deformations made by those skilled in the art on the basis of the specific embodiments of the utility model also belong to the protection scope of the utility model.
