Description

Technical Field

[0001] This utility model relates to the technical field of experimental devices for freshwater fish rearing, and more specifically to an experimental device suitable for conducting experiments on the utilization efficiency of freshwater fish feed. Background Technology

[0002] Freshwater fish feed utilization efficiency refers to the proportion of feed digested and absorbed by freshwater fish during the aquaculture process, which directly affects aquaculture costs and economic benefits. Therefore, conducting experiments on this topic is essential.

[0003] Currently, experiments on freshwater fish feed utilization efficiency typically involve raising freshwater fish in experimental ponds, feeding them regularly, and weighing them periodically. However, to accurately weigh the fish and avoid the influence of fish feces and feed residue in the water, it is usually necessary to remove the fish from the water, which undoubtedly increases the workload. This is especially true when observing numerous freshwater fish samples simultaneously, resulting in high workload and low efficiency.

[0004] Therefore, providing an experimental apparatus suitable for conducting experiments on the utilization efficiency of freshwater fish feed is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an experimental device suitable for conducting experiments on the feed utilization efficiency of freshwater fish, which can weigh fish efficiently, quickly and easily, thus facilitating experiments on the feed utilization efficiency of freshwater fish.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An experimental apparatus for studying the feed utilization efficiency of freshwater fish includes a support frame, multiple experimental boxes, multiple separating net boxes, multiple lifting mechanisms, and multiple weighing sensors. The multiple experimental boxes are placed sequentially on the support frame in a horizontal direction. Each separating net box includes a filter box and two support rods connected to its two sides. Each filter box is placed inside the experimental box via the two support rods. The multiple lifting mechanisms are located on both sides of the support frame and directly below the multiple support rods. The multiple weighing sensors are installed on top of the multiple lifting mechanisms.

[0008] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0009] Under the action of the lifting mechanism, the separation net cage is lifted from the experimental box, separating the freshwater fish in the separation net cage from the water and feces and feed residue in the experimental box. During this process, the weighing sensor weighs the freshwater fish, realizing efficient, fast and simple weighing of fish, which provides convenience for carrying out freshwater fish feed utilization efficiency experiments.

[0010] Furthermore, the support frame includes a support frame and multiple support legs. The support frame has slots on both sides, and the experimental box has insert plates on both sides. Two insert plates are respectively inserted into two slots. The multiple support legs are respectively fixed to the bottom of the support frame.

[0011] Furthermore, each of the lifting mechanisms includes a hydraulic cylinder and a support block, with the hydraulic cylinders vertically distributed; the support block is fixed to the top of the hydraulic cylinder telescopic rod and located directly below the support rod; the weighing sensor is installed on the top of the support block.

[0012] Furthermore, the top of the support block has a support groove; the weighing sensor is installed in the support groove.

[0013] The beneficial effect of adopting the above-mentioned further technical solution is that it can improve the stability of the separated cage during the lifting process.

[0014] Furthermore, the pore size of the filter box is smaller than the size of freshwater fish, but larger than the size of freshwater fish feces and feed residue.

[0015] The beneficial effect of adopting the above-mentioned further technical solution is that when the separation cage is separated from the experimental box, freshwater fish will not leak out of the filter holes of the filter box, while freshwater fish feces and feed residue will leak out of the filter holes.

[0019] 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.

[0020] like Figure 1-2 As shown in the figure, this utility model discloses an experimental device suitable for conducting experiments on the feed utilization efficiency of freshwater fish. It includes a support frame 1, multiple experimental boxes 2, multiple separating net boxes 3, multiple lifting mechanisms 4, and multiple weighing sensors 5. The multiple experimental boxes 2 are placed horizontally on the support frame 1, and each experimental box 2 is filled with water. Each separating net box 3 includes a filter box 31 and two support rods 32 connected to its two sides. Each filter box 31 is placed inside the experimental box 2 via the two support rods 32. The multiple lifting mechanisms 4 are located on both sides of the support frame 1 and directly below the multiple support rods 32. The multiple weighing sensors 5 are installed on the top of the multiple lifting mechanisms 4. Under the action of the lifting mechanisms 4, the separating net boxes 3 are lifted from the experimental boxes 2, separating the freshwater fish in the separating net boxes 3 from the water and feces / feed residue in the experimental boxes 2. During this process, the weighing sensors 5 weigh the freshwater fish, achieving efficient, rapid, and convenient weighing of the fish, providing convenience for conducting experiments on the feed utilization efficiency of freshwater fish.

[0021] Specifically, the support frame 1 includes a support frame 11 and multiple support legs 12. The support frame 11 has slots on both sides, and the experimental box 2 has insert plates on both sides. The two insert plates are respectively inserted into the two slots. The multiple support legs 12 are respectively fixed to the bottom of the support frame 11.

[0022] Specifically, each lifting mechanism 4 includes a hydraulic cylinder 41 and a support block 42. The hydraulic cylinder 41 is vertically distributed; the support block 42 is fixed to the top of the telescopic rod of the hydraulic cylinder 41 and located directly below the support rod 32; the weighing sensor 5 is installed on the top of the support block 42.

[0023] To further optimize the technical solution of this utility model, the top of the support block 42 has a support groove; the weighing sensor 5 is installed in the support groove, which can improve the stability of the separation net box 3 during the lifting process.

[0024] Specifically, the aperture of the filter holes in filter box 31 is smaller than the size of freshwater fish but larger than the size of freshwater fish feces and feed residue. This ensures that when the separation net box 3 is separated from the experimental box 2, freshwater fish will not leak out of the filter holes in filter box 31, while freshwater fish feces and feed residue will leak out of the filter holes.

[0025] The working process of this utility model:

[0026] When it is necessary to weigh the freshwater fish, the hydraulic cylinder 41 is driven, and the telescopic rod drives the support block 42 at its top to rise. Then, the support rods 32 on both sides of the filter box 31 enter the support groove of the support block 42 and press on the weighing sensor 5. When the filter box 31 is completely separated from the water in the experimental chamber 2, the hydraulic cylinder 41 stops moving. After the filter box 31 stabilizes, only the freshwater fish are left in the filter box 31. The weighing sensor 5 obtains the weight of the freshwater fish (both weighing sensors 5 obtain the weight, the two weights are added together and divided by 2 to obtain the total weight of the freshwater fish + the separation net box 3, and then the weight of the separation net box 3 is subtracted to obtain the weight of the freshwater fish). Then, the hydraulic cylinder 41 is driven to lower the telescopic rod, and the filter box 31 re-enters the experimental chamber 2 for continued observation of the freshwater fish.
