Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a feeding table used for feeding fish species in a net cage. Background Art

[0002] Cage aquaculture is a new aquaculture method developed in my country in the past 20 years. It is divided into feed cages and non-feed cages according to the different stocking species. Usually, during the aquaculture production process of feed cages, a dense mesh mesh is added to the bottom of the cage as a lining net to reduce bait loss and improve bait utilization. Feed is generally fed by throwing at fixed points in the feeding area.

[0003] However, due to the large size and fast growth of fish species, the water body is stirred up during the competition for food, so that the feed cannot sink vertically due to its gravity, but drifts out of the cage or sinks to the bottom of the water with the increase of the water flow, resulting in the feed not being eaten by the fish in time or being unable to be eaten, causing feed waste. In addition, the uneven feeding of fish species leads to uneven sizes of fish species. If the feeding table is soaked in water for too long, the accumulated and adhered residual bait and fish feces will rot and decompose, mold and stink, and become a breeding ground for pests and bacteria. If the feeding table is cleaned too frequently during the large growth period of fish species, the fish bodies may be injured by friction against the net during the competition for food. If it is a breeding cage set up in a pond, the feed will be deposited at the bottom of the pond and rot and mold will seriously damage the ecological environment of the water body, not benefit the healthy growth of fish species, and reduce the breeding efficiency. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a feeding table for feeding fish in a net cage, which is characterized by comprising a steel bar frame, a polyethylene net cage, a fixing rope, a connecting buckle, and an upper hanging rope. The outside of the steel bar frame is wrapped and connected by the polyethylene net cage, and the four top corners of the polyethylene net cage and the four bottom corners of the steel bar frame and the four upper sides of the polyethylene net cage are connected to the four bottom sides of the steel bar frame by fixing ropes. The steel bar frame consists of a steel bar frame, steel bar columns and diagonal steel bars. Two of the steel bar frames are arranged in upper and lower relative positions and a number of steel bar columns are welded between the two steel bar frames. The diagonal steel bars are welded and connected between the two diagonals of the steel bar frame at the bottom. The four corners of the upper end of the polyethylene net cage are connected to the upper hanging rope by connecting buckles.

[0005] Specifically, the lower opening of the steel frame is wrapped and closely connected with a polyethylene mesh box, and the upper opening of the steel frame is a feeding opening.

[0006] Specifically, the four sides of the polyethylene net box and the four sides of the steel frame are arranged at intervals and connected by fixed ropes.

[0007] Specifically, the other end of the upper suspension rope is connected to the aquaculture cage fixing frame.

[0008] Specifically, the bottom surface of the polyethylene mesh box is connected to the diagonal steel bars through fixed ropes. The fixed ropes are polyethylene ropes, the length of which is determined according to the height of the steel bar frame, and the number of which is determined according to the diameter of the steel bar frame.

[0009] Specifically, the upper hanging rope is made of polyethylene rope, the length of which is determined according to the height of the aquaculture cage fixing frame, and a knot is tied on the upper hanging rope according to the water depth of the feeding table to keep the balance of the feeding table.

[0010] Specifically, the connecting buckle connects the four corners of the upper end of the polyethylene mesh box with the four corners of the upper end of the steel frame, and the connecting buckle is made of polyethylene rope, which is folded in half and fastened at the open top to form the connecting buckle.

[0011] The feeding table designed by the utility model has a simple overall structure and is easy to manufacture and operate. The diameter and height of the steel frame can be designed according to the size of the breeding cage and the specifications of the fish species, ensuring that the feed will not flow out of the feeding table and sink into the water outside the feeding table during the feeding process of the fish species, thereby preventing the feed from falling into the bottom of the pond and becoming rotten and moldy, thereby affecting the ecological environment of the water body.

[0012] The feeding table designed by the utility model is placed in the center of the breeding net box. When feeding, the feed is thrown from the feeding port to the center of the feeding table. The mesh of the polyethylene net box wrapped outside the steel frame can be adjusted and replaced at any time according to the fish species specifications and feed particle size, ensuring that the feed does not escape or leak, thereby reducing feed waste.

[0013] The number of fixed ropes and steel columns on the four corners and four sides can be adjusted and designed according to the specifications of the steel frame to ensure that the polyethylene cage wrapped outside the steel frame is compactly installed on the steel frame to avoid the situation where fish are trapped due to the large distance between the algae attached to the polyethylene cage and the steel frame after entering the water;

[0014] The utility model connects the upper hanging rope with the polyethylene net box through a connecting buckle, and the other end of the upper hanging rope is connected to the fixing frame of the breeding net box. The food table is easy to replace, easy to clean and simple to operate.

[0015] The upper hanging ropes in the utility model are connected with the four corners of the upper end of the polyethylene net box. The four upper hanging ropes can be marked and knotted according to the water depth of the feeding table, so that the feeding table can maintain balance after entering the water, and avoid the feed being piled up in one place due to the different water depths of the four corners of the feeding table, which is not conducive to fish feeding; at the same time, it can ensure that the particles of feed that are not eaten by the fish in the sinking process will not fall outside the feeding table due to the action of water flow, and the fish with weak feeding ability can eat the feed at the bottom of the feeding table, so that each fish can get the opportunity to eat, reducing the uneven specifications and sizes of fish bodies caused by different feeding abilities.
