Description

Technical Field

[0001] This utility model belongs to the field of fish farming screening technology, and in particular relates to an adjustable grading screen device for slender fish farming. Background Technology

[0002] Slimming fish farming is a special ecological farming model. Its core goal is not to make fish gain weight quickly, but to significantly improve the meat quality and taste of fish through a period of special treatment. During the farming period, even fish from the same batch will have differences in size / weight, fat content, and health status before entering the slimming tank. Therefore, fish need to be graded and screened for refined management and farming.

[0003] Currently, during the fish sorting process, the fish are driven towards the tilted screen. However, the bottom-dwelling nature of the fish and the mixed sorting method of different sizes cause large fish to block smaller fish from passing through the screen, resulting in blockages that affect the sorting efficiency. It is also easy for some small fish to be carried into the large fish pond by the large fish, causing sorting chaos.

[0004] To address the aforementioned issues, this application proposes an adjustable grading screen device for slender fish farming. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable grading screen device for slim fish farming, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an adjustable grading screen device for slim fish farming, including a fish sorting box, an inlet pipe at its right end, a water spray seat and a cover plate above it.

[0008] The pre-separation mechanism is located inside the right end of the fish separation box. It includes a horizontal bar in the front-to-back direction and a guide bar in the left-to-right direction. The horizontal bar is distributed at equal intervals along the direction from the lower right to the upper left. One end of the guide bar is fixed to the left side of the horizontal bar and is distributed at equal intervals along the front-to-back direction.

[0009] The fish distribution box is equipped with a grading screen inside the left end. The fish distribution box is divided into a pre-division area on the right and a transfer area on the left by the grading screen. The transfer area is equipped with partitions arranged vertically and horizontally, corresponding to the outlet at the front left end of the fish distribution box.

[0010] Preferably, the water spray base is located above the guide rod, and a nozzle tilted to the lower left is fixedly installed at its lower end.

[0011] Preferably, the mesh size of the grading screen decreases from top to bottom.

[0012] Preferably, the right end of the partition mesh is directly opposite a front-to-back wire of the grading screen, and the cavity between adjacent partition meshes corresponds to an opening at the same height as the outlet.

[0013] Preferably, the spacing between adjacent crossbars decreases from top to bottom.

[0014] Preferably, the guide rods are arranged in the front-to-back direction to form a longitudinal isolation strip.

[0015] Preferably, the guide rods are arranged vertically to form a transverse isolation strip.

[0016] This utility model has the following beneficial effects:

[0017] This invention uses a pre-sorting mechanism to create a partitioned structure at the front end, which drives large fish upwards and small fish downwards towards the grading screen. This ensures that fish in the upper and lower areas can quickly pass through the grading screen for differentiation, while also preventing large fish from carrying away or blocking small fish when they move upwards.

[0018] This invention combines the upper and lower grading arrangement of the screen with the upper and lower swimming areas of fish of different sizes for screening. The grading screen can be set with different mesh sizes at the top and bottom. When the fish pass through the grading screen, they are directly graded and enter the cavity corresponding to the outlet for transfer, thus forming an integrated grading and screening effect. This replaces the traditional multi-stage screening method, which can reduce the overall space occupied by the equipment. At the same time, the integrated method also facilitates the transfer and management of the fish.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Please see Figure 1-4 As shown, this utility model is an adjustable grading screen device for slim fish farming, including a fish sorting box 1, an inlet pipe 11 at its right end, a water spray seat 12 above, and a cover plate 13.

[0036] The pre-separation mechanism 17 is located inside the right end of the fish separation box 1. It includes a crossbar 171 and a guide bar 172. The crossbar 171 is fixedly installed in the front-back direction, and the guide bar 172 is fixedly installed on the left side of the crossbar 171 in the left-right direction. The crossbars 171 are evenly distributed at an angle from the lower right to the upper left and are also evenly distributed in the front-back direction. A fixed swimming path is formed between adjacent guide bars 172, which fixes fish of different sizes in this area to swim to the left, thereby avoiding the blockage problem caused by mixed swimming.

[0037] The left end of the fish distribution box 1 is equipped with a grading screen 15, with the mesh size decreasing from top to bottom. The area to the right of the grading screen 15 in the fish distribution box 1 is a pre-division area, and the area to the left of the grading screen 15 is a transfer area. The transfer area is equipped with partitions 16 arranged vertically and vertically, and a temporary storage cavity is formed between adjacent partitions 16, which corresponds to the outlet 14 at the same height at the front left end of the fish distribution box 1.

[0038] Furthermore, the water spray base 12 covers the area from the right end of the uppermost guide rod 172 to the adjacent left end. The front end of the water spray base 12 is equipped with a suction pipe via a suction pump, which is connected to the right end of the fish distribution box 1 near the upper end. An isolation net is installed inside the suction port. The lower end of the water spray base 12 is fixedly equipped with a nozzle 121 that tilts downward to the left. The released water flow directly acts on the water, causing the small fish in the upper area to move downward. This not only fits the small mesh of the lower area of ​​the grading screen 15, but also improves the efficiency of passing through the grading screen 15 (the suction pump, suction pipe, water spray base, and nozzle are all mature commercial products on the market and will not be described in detail here).

[0039] Furthermore, the right end of the partition 16 is directly opposite a front-to-back direction wire of the grading screen 15, and the two are close together to reduce the gap between the openings. Small fish are sewn into the openings. The wire of the grading screen 15 is made of plastic with a smooth surface.

[0040] Furthermore, the spacing between adjacent horizontal bars 171 decreases from top to bottom, with the lower end used for small fish to pass through and the upper end used for large fish to pass through.

[0041] Furthermore, the guide rods 172 are arranged in the front and back directions to form a longitudinal isolation zone 17201, which is used to isolate fish in different areas in front and behind, ensuring that their swimming path is fixed, which not only improves efficiency but also avoids blocking subsequent fish.

[0042] Furthermore, the vertical arrangement of the guide rods 172 forms a horizontal isolation zone 17202, which is used to block large fish in the upper area from moving downstream, while small fish in the upper area move downstream under the action of the water jet from the nozzle 121.

[0043] Understandably, this invention pre-divides the fish population before screening, allowing fish of different sizes to move in different sections of the grading screen 15. This integrates the screening of different fish populations into the same fish sorting box 1, reducing space requirements and overall equipment costs.

[0044] A specific application of the operation flow in this embodiment is as follows: When the mixed fish enter the fish sorting box 1 through the inlet pipe 11, they are first separated by the crossbar 171. Small fish pass through directly, while large fish are blocked and swim upwards. The fish that pass through the crossbar 171 swim towards the grading screen 15. During this swimming, water is sprayed downwards by the nozzle 121, causing the small fish in the upper area to swim downwards, while the large fish maintain their path due to the obstruction of the transverse isolation strip 17202. This creates a pre-separation effect of large fish at the top and small fish at the bottom. At the same time, during the swimming, the longitudinal isolation strip 17201 is used to separate the fish. The fish in the left and right areas are separated, which not only fixes their swimming path but also prevents them from gathering in the same area and causing blockage when they reach the grading screen 15. Furthermore, the fish that reach the grading screen 15 are graded vertically by the longitudinal isolation band 17201. Fish that meet the mesh size of the grading screen 15 can pass directly into the transfer area of ​​the fish distribution box 1, while larger fish are guided by the inclined structure of the grading screen 15 to swim upward and continue to try to pass through the grading screen 15. In this way, fish of different sizes are graded and screened to the upper and lower areas corresponding to the outlet 14 for transfer.
