Description

Technical Field

[0001] The utility model relates to the field of ornamental fish breeding equipment, in particular to an automatic collection device for ornamental fish eggs. Background Art

[0002] Ornamental fish breeding equipment is a general term for various tools and devices used for raising and cultivating ornamental fish. An aquarium is the core equipment for ornamental fish breeding. Aquariums are made of various materials, such as glass and acrylic. Aquariums of different sizes and shapes can meet the breeding needs of different species of ornamental fish. Aquariums are usually equipped with a filtration system and a lighting system. For some rare ornamental fish species, their numbers may be relatively scarce. Collecting fish eggs can be used for artificial hatching and cultivation to increase the numbers of these species, thereby better protecting them from extinction.

[0003] In the prior art, such as the "Automated High-Efficiency Fish Egg Collection Device" with the publication number CN218451292U, which includes a spawning pool, an incubator, a first filter screen and a second filter screen. The bottom of the spawning pool is in an inverted cone shape. The diameters of multiple first filter screens are different. The axes of the first filter screens coincide with the axis of the bottom of the spawning pool and are erected on the bottom of the pool. The second filter screen is arranged at the drainage outlet. The pore diameter of the first filter screen is more than twice the diameter of the fish eggs. In the automated high-efficiency fish egg collection device provided by the utility model, due to the layered filtration of the first filter screen, the inverted cone-shaped bottom of the pool speeds up the filtration efficiency of the first filter screen, so that there are fewer impurities in the water flow passing through the second filter screen, making it not easy for the second filter screen to be blocked, and also making the water flow rate in the drain pipe large and the flow velocity fast, accelerating the fish egg collection speed. The process of fish eggs entering the incubator has a relatively high degree of automation, reducing the labor cost.

[0004] In the above patent, the first filter screen and the second filter screen are set. The pore diameter of the first filter screen is more than twice the diameter of the fish eggs, and the pore diameter of the second filter screen is larger than the diameter of the fish eggs and smaller than that of the first filter screen. Although it can achieve the purpose of layered filtration and improve the filtration efficiency and the fish egg collection speed, the pore diameters of the filter screens are not uniform, making the water flow and fish eggs pass through the filter screens unevenly, and the pressure on the fish eggs when passing through the filter screens is uneven. When the water flow passes through the filter screen, the speed will change. Especially at the pores of the filter screen, local turbulence and pressure changes may occur in the water flow. Moreover, when the fish eggs pass through the filter screen along with the water flow, they may be impacted by these unstable water flows, resulting in the rupture of the outer shell of the fish eggs or damage to the internal structure, easily causing damage to the fish eggs, and thus it is difficult to ensure that the fish eggs will not be damaged during the layered filtration. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an automatic collection device for ornamental fish eggs, which not only achieves the purpose of layered filtration but also reduces the water flow velocity. It not only prevents fish eggs from being damaged during fish egg collection but also provides a quiet environment for ornamental fish to avoid disturbing the ornamental fish.

[0006] To achieve the above object, the utility model is realized by the following technical solutions: An automatic ornamental fish egg collection device includes a collection box for collecting fish eggs. A funnel for communicating with the bottom of the fish tank is fixedly installed at the upper end of the collection box. A sieve area and a collection area are provided inside the collection box. A ring-shaped filter plate for separating the sieve area from the collection area is fixedly installed between the funnel and the collection box. The funnel includes an upper collection hopper in an inverted conical shape and a lower collection hopper for filtering. The upper end of the lower collection hopper is conical, and the cross-section of its bottom end is circular. The upper collection hopper and the lower collection hopper are communicated. A plurality of filter holes for passing fish eggs are provided at the outermost circle of the lower collection hopper.

[0007] A conveyor for conveying fish eggs towards the filter holes is rotatably installed inside the lower collection hopper. The conveyor is spiral. An aggregator for aggregating fish eggs inward is rotatably installed inside the collection area, and both sides of the cross-section are provided as inclined surfaces. The aggregator is spiral, and the spiral direction is set opposite to the spiral direction of the conveyor. A through hole is provided at the bottom end of the collection box. A detachable ovulation mechanism is communicated with the bottom end of the collection box. The ovulation mechanism is used for collecting the separated fish eggs and also for discharging the fish eggs.

[0008] Preferably, a barrier net for preventing ornamental fish from passing through is fixedly installed at the communication part between the upper collection hopper and the lower collection hopper.

[0009] Preferably, a turntable fixed to the conveyor is rotatably installed inside the lower collection hopper. A filter disk fixed to the fish aggregator is rotatably installed inside the through hole. A connecting shaft is fixedly connected between the filter disk and the turntable, and the turntable, the connecting shaft, and the filter disk are integrally arranged.

[0010] Preferably, the ovulation mechanism includes a fish egg hopper for collecting fish eggs, an ovulation pipe communicated with the fish egg hopper, and a valve communicated with the ovulation pipe.

[0011] Preferably, one end of the bottom end of the filter disk is fixedly connected to one end of a rotating rod, and the other end is connected to an external motor.

[0012] Preferably, a rotating rod is rotatably installed inside the ovulation pipe, and the intersection between them is hermetically arranged.

[0013] Preferably, sludge suction pipes for extracting ornamental fish feces and foreign matters are installed inside both the lower collection hopper and the collection box, and the two sludge suction pipes are connected to an external sludge suction pump.

[0014] Compared with the prior art, the utility model has the following beneficial effects: for the automatic ornamental fish egg collection device, by setting the conveyor and the aggregator to be spiral, the conveyor is used to slowly convey fish eggs and impurities outwards, and the aggregator is used to aggregate inwards. In this process, the flow rate of the water flow is reduced to prevent the fish eggs from being damaged. Moreover, the fish eggs and impurities are slowly filtered layer by layer, so that large particle feces and foreign objects are separated from the fish eggs. The fish eggs and small particle feces aggregate inwards in the collection area. By setting both sides of the cross-section of the aggregator to be inclined planes, during the aggregation process, the fish eggs float along the inclined planes, and the lower particle feces sink, realizing the separation of the fish eggs and the small particle feces, reducing the degree of contamination of the fish eggs. Moreover, with the conical design of the funnel, the flow rate of the water flow is greatly reduced, preventing the ornamental fish from being disturbed and providing a relatively quiet environment for the ornamental fish.

[0020] As Figures 1 - 4As shown in the figure, an automatic ornamental fish egg collection device includes a collection box 1 for collecting fish eggs. A funnel 2 for communicating with the bottom of the fish tank is fixedly installed at the upper end of the collection box 1. Inside the collection box 1, there are a screening area 3 and a collection area 4. A ring-shaped filter plate 5 for separating the screening area 3 from the collection area 4 is fixedly installed between the funnel 2 and the collection box 1. The funnel 2 includes an upper collection hopper 18 in an inverted conical shape and a lower collection hopper 6 for filtering. Mud suction pipes 17 for extracting ornamental fish feces and foreign objects are installed inside both the lower collection hopper 6 and the collection box 1, and the two mud suction pipes 17 are connected to an external mud suction pump. The large-particle feces and foreign objects after filtration are extracted through the mud suction pump and the two mud suction pipes 17. The upper end of the lower collection hopper 6 is conical, and the cross-section of its bottom end is circular. The upper collection hopper 18 and the lower collection hopper 6 are connected. The cooperation between the lower collection hopper 6 and the upper collection hopper 18 reduces the flow rate of the water flow in the upper collection hopper 18 during the filtration process, improves the stability of the water flow in the upper collection hopper 18 and the fish tank, and provides a quiet environment for the ornamental fish. A barrier net 12 for preventing ornamental fish from passing through is fixedly installed at the connection between the upper collection hopper 18 and the lower collection hopper 6. On the one hand, it allows the feces, food residues, and fish eggs of the ornamental fish to enter the lower collection hopper 6 through the barrier net 12, preventing branches and fallen leaves from entering the lower collection hopper 6 and causing blockage. On the other hand, it prevents ornamental fish from entering the lower collection hopper 6. Inside the lower collection hopper 6, a conveyor 8 fixedly connected to a turntable 13 is rotatably installed. Inside the through hole 10, a filter disk 14 fixedly connected to a fish aggregator 9 is rotatably installed. A connecting shaft 15 is fixedly connected between the filter disk 14 and the turntable 13, and the turntable 13, the connecting shaft 15, and the filter disk 14 are integrally arranged to realize the linkage between the aggregator 9 and the conveyor 8. A number of filter holes 7 for passing fish eggs are opened in the outermost circle of the lower collection hopper 6;

[0021] Inside the lower collection hopper 6, a conveyor 8 for conveying fish eggs towards the filter holes 7 is rotatably installed. The conveyor 8 is spiral-shaped, ensuring that the fish eggs are slowly conveyed outwards during the rotation of the conveyor 8, reducing the water flow rate, and avoiding damage to the fish eggs during the conveying process. Inside the collection area 4, an aggregator 9 for aggregating fish eggs inwards is rotatably installed, and both sides of the cross-section are set as inclined planes. The aggregator 9 is spiral-shaped, and the spiral direction is opposite to that of the conveyor 8. A through hole 10 is opened at the bottom end of the collection box 1, and a detachable ovulation mechanism 11 is connected to the bottom end of the collection box 1. The ovulation mechanism 11 is used for collecting the separated fish eggs and also for discharging the fish eggs. The ovulation mechanism 11 includes a fish egg hopper 111 for collecting fish eggs, an ovulation pipe 112 communicating with the fish egg hopper 111, and a valve 113 communicating with the ovulation pipe 112. A rotating rod 16 is rotatably installed inside the ovulation pipe 112, and the intersection between the two is sealed. One end of the rotating rod 16 is fixedly connected to the filter disk 14, and the other end is connected to an external motor.

[0022] When in use, firstly, the upper collecting bucket 18 at the upper end of the funnel 2 is installed at the bottom of the ornamental fish tank, so that the fish eggs in the fish tank flow into the upper collecting bucket 18, and the fish eggs, feces and foreign matter flow along the water flow through the upper collecting bucket 18 and the lower collecting bucket 6 to the collecting box 1, and the filter plate 5 installed between the upper collecting bucket 18 and the lower collecting bucket 6 is used to block branches and leaves. Then, the rotating rod 16 is driven by an external motor to rotate slowly. Since the rotating disk 13, the connecting shaft 15 and the filter disk 14 are integrated, When the rotating rod 16 rotates, the rotating disk 13, the connecting shaft 15 and the filter disk 14 are linked, and the rotating disk 13 and the filter disk 14 respectively drive the conveyor 8 and the aggregator 9 to rotate. When the conveyor 8 rotates, the fish eggs are transported to the filter holes 7 on the outer ring of the collecting bucket 6 and arrive at the screening area 3. The filter holes 7 cooperate with the barrier net 12 to filter large particles of foreign matter and feces, and small particles of feces, foreign matter and fish eggs enter the collecting area 4. When the aggregator 9 rotates, the fish eggs are gathered to the center position thereof. The force is greater than that of the fish eggs, and both sides of the cross section of the coagulator 9 are set to inclined planes. Therefore, in the process of gathering, the inclined plane of the coagulator 9 is easier to push the fish eggs to float, and a part of the small particles of feces sink, and the other part enters the inside of the coagulator 9, so that the separation of fish eggs and small particles of feces is realized. Due to the spiral arrangement of the conveyor 8 and the coagulator 9, the fish eggs, feces and foreign matter are slowly flowed along the water flow, and the rate of flow is reduced, so as to prevent the situation that the fish eggs are damaged due to the excessive water flow, and the fish eggs are protected. Finally, the fish eggs and the small particles of feces enter the fish egg bucket 111 of the ovulation mechanism 11 through the filter disc 14, and then enter the oviduct 112, and are discharged from the oviduct 112 by opening the valve 113. It should be noted that when the fish eggs reach the center position of the coagulator 9, they will be out of contact with the coagulator 9, and then sink along the water flow. Since the lower particles of feces will sink first, the small particles of feces will be discharged first, and the fish eggs will be collected by the external collection device at last.
