Description

Technical Field

[0001] The invention relates to the technical field of fish egg collection, in particular to a puffer fish egg collection box capable of filtering impurities and a collection method thereof. Background Art

[0002] The dark-striped pufferfish belongs to the class of bony fishes, the order of Tetraodontiformes, the family of Tetraodontiformes, and the genus of Tetraodontiformes. It is a typical marine and freshwater migratory species. It is mainly distributed in the East China Sea, the Yellow Sea, and the middle and lower reaches of the Yangtze River in my country. Because of its delicious meat, it is often called one of the "three fresh delicacies of the Yangtze River". The so-called pufferfish is a treasure. In addition to the common male fish gonad "white"; the fish skin has the effect of improving gastrointestinal digestion; the fish liver has rich nutritional value and health care effects; the pufferfish toxin TTX can be widely used in drug rehabilitation, anti-cancer, analgesia, anesthesia, and improving sexual function. Therefore, it is widely praised by consumers in the market. With the expansion of the scale of breeding, how to improve the fertilization rate, hatching rate, egg production, fry survival rate, and reduce parent fish mortality in the process of dark-striped pufferfish seed cultivation has always attracted much attention. At present, the common hatching methods are artificial spawning and fertilization hatching, and natural spawning and hatching. Artificial spawning and fertilization methods have problems such as the need to train professional spawning personnel, high mortality rate of post-spawning broodstock, the need for independent induced spawning pools, independent post-spawning care pools, and the debonding of fish eggs after spawning. Therefore, natural spawning and hatching methods were born. In comparison, natural spawning has the advantages of not requiring the training of professionals, not being restricted by site factors, not requiring professional care after spawning, and reducing the mortality rate of post-spawning broodstock. However, the collection of fertilized eggs after natural spawning requires a large number of people, is time-consuming and cumbersome, and there are a lot of impurities in the collection process, which are difficult to hatch directly without filtering and screening; in addition to the influence of impurities, the eggs of dark-striped pufferfish are sticky eggs, and there is a phenomenon of mutual accumulation after natural spawning, causing local hypoxia and fungal infection that affects the hatching rate and survival rate.

[0003] The current common method is to collect the fertilized eggs after natural spawning of fish before artificial hatching, and then process them. A special puffer fish egg collection box is required for collection.

[0004] However, there are still some problems with the existing fish egg collection box:

[0005] The existing collection box usually uses a water pump to extract the fertilized egg mixture, but the water pump usually needs to rotate at a high speed, which is easy to cause the loss or direct death of the fertilized eggs, affecting the hatching rate and survival rate of the fertilized eggs, causing certain losses;

[0006] The existing fish egg collection box has a poor filtering effect on impurities in the fish egg mixture, and can usually only filter larger impurities inside. For small puffer eggs with a diameter of only 0.88-1.21 mm, impurities in the mixture with a particle size smaller than that of fertilized eggs cannot be removed, resulting in incomplete filtration. At the same time, sticky eggs will clog the filter during filtration, making it difficult to clean them. The existing collection box cannot effectively handle the hatching work of puffer fish after natural spawning.

[0007] In order to solve the problems in the related technology, no effective solution has been proposed so far. In order to solve the problems of removing impurities, debonding, dispersing and collecting fertilized eggs of dark-striped pufferfish after natural spawning, the present invention relates to the field of fish egg collection technology, and an innovative design is made on the basis of the original fish egg collection box, specifically a pufferfish egg collection box with filterable impurities and a collection method thereof.

[0015] Preferably, the right end of the first reciprocating screw is keyed to a first bevel gear, the stirring rod is designed as a cylindrical structure, and the stirring rods are distributed in a circular array with the stirring shaft as the center, the upper end of the stirring shaft passes through the support plate, and the upper end of the stirring shaft is keyed to a second bevel gear, and the second bevel gear is meshingly connected to the first bevel gear.

[0016] By adopting the above technical solution, the first reciprocating screw drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear, the stirring shaft and the stirring rod to rotate synchronously, thereby stirring the puffer fish egg mixture on the right side of the partition, dispersing the sticky fertilized eggs, preventing accumulation, and facilitating subsequent filtration processing.

[0017] Preferably, a sealing tube is fixedly installed on the upper left end of the support plate, and a first one-way valve is connected to the upper left end of the sealing tube, and the first one-way valve is conductively connected to the conduit;

[0018] A piston is slidably connected inside the sealing tube, and a movable rod is connected to the right end of the piston. The right end of the movable rod passes through the outside of the sealing tube, and a transmission plate is connected to the right end of the movable rod, and the transmission plate is threadedly connected to the first reciprocating screw.

[0019] By adopting the above technical solution, the first reciprocating screw drives the transmission plate, the movable rod and the piston to move horizontally. When the piston moves rightward inside the sealing tube, the puffer fish egg mixture on the right side of the partition can be extracted through the cooperation of the first one-way valve and the conduit.

[0020] Preferably, two groups of sealing tubes are provided, and the left ends of the opposite sides of the two groups of sealing tubes are connected to the second one-way valve, the lower end of the left side of the support plate is connected to a diverter tube, and the upper end of the diverter tube passes through the support plate and is connected to the second one-way valve, and the second one-way valve is arranged in the opposite direction to the first one-way valve.

[0021] By adopting the above technical solution, through the arrangement of the second one-way valve and the shunt pipe, when the piston moves to the left inside the sealing tube, the puffer fish egg mixture extracted inside can be transported to the shunt pipe to flow out, and the liquid transport structure is not easy to cause damage to the fertilized eggs, and the puffer fish egg mixture is transported intermittently, which is convenient for filtering without blockage and incomplete filtration due to excessive flow.

[0022] Preferably, the front and rear sides of the upper end of the filter box are penetrated with a first discharge port, and the left and right ends of the filter box are conductively connected with a second discharge port, the lower end of the second discharge port is provided with a guide groove, and the front end of the guide groove penetrates the front end of the collection box body, and a clean water pipe is provided inside the guide groove;

[0023] The upper end of the filter box is fixedly connected with a filter screen, and the aperture of the filter screen is larger than the aperture of the filter box, and the upper end surface of the filter screen is arranged in the same horizontal plane as the lower end of the first discharge port.

[0024] By adopting the above technical scheme, through the cooperation between the filter screen and the first discharge port, after the filter screen retains larger impurities, the vibration generated when the filter box is shaken can make the impurities discharged from the first discharge port, and the pore size of the filter screen is larger than the puffer fish eggs. After filtering, the puffer fish eggs fall into the filter box, and the puffer fish eggs are retained by the filter box, and impurities smaller than the puffer fish eggs are filtered out.

[0025] Preferably, the left end of the dual-axis motor is keyed to a driving pulley, a transmission shaft runs through the left side of the collection box body, and the transmission shaft is connected to the collection box body bearing;

[0026] The left end of the transmission shaft is fixedly connected with a driven pulley, and a transmission belt is connected between the driven pulley and the driving pulley.

[0027] By adopting the above technical solution, the dual-axis motor drives the rotation of the driving pulley, and the driving pulley drives the driven pulley and the transmission shaft to rotate synchronously through the transmission belt.

[0028] Preferably, the right end of the transmission shaft is fixedly connected with a movable disk, and the right end of the movable disk is eccentrically connected with a limit rod, the upper left end of the filter box is bolted with a connecting rod, and the left side of the connecting rod is connected with a limit plate;

[0029] A limiting groove is arranged inside the limiting plate, and the right end of the limiting rod passes through the limiting groove, and the limiting groove and the limiting rod form a sliding limiting structure.

[0030] By adopting the above technical solution, the movable disk and the limit rod are driven to rotate synchronously by the rotation of the transmission shaft. When the limit rod rotates, it slides inside the limit groove and drives the limit plate, connecting rod and filter box to reciprocate horizontally back and forth synchronously, thereby improving the filtration efficiency.

[0031] Preferably, a second reciprocating screw rod passes through the middle of the lower end of the filter box, and the second reciprocating screw rod is connected to the filter box bearing, a cleaning plate is slidably connected inside the filter box, and the middle of the cleaning plate is threadedly connected to the second reciprocating screw rod, and the lower end of the cleaning plate is connected to flexible bristles;

[0032] The left end bearing of the second reciprocating screw is connected with a transmission gear, the left inner wall of the collection box body is connected with a transmission rack, and the transmission gear is meshedly connected with the transmission rack.

[0033] By adopting the above technical solution, through the setting of the second reciprocating screw, the cleaning plate and the flexible bristles, when the filter screen reciprocates, the transmission rack drives the rotation of the transmission gear and the second reciprocating screw, thereby driving the movement of the cleaning plate and the flexible bristles to clean the retained sticky fertilized eggs on the upper surface of the bottom of the filter box.

[0035] By adopting the above technical solution, through the cooperation of the inner ratchet and the pawl, when the transmission rack cooperates with the transmission gear, the transmission gear can only drive the unidirectional rotation of the second reciprocating screw, thereby ensuring that the cleaning plate and the flexible bristles can reciprocate normally.

[0036] Preferably, the method comprises the following steps:

[0037] Step 1: Pour the mixed liquid of puffer fish eggs collected after natural spawning into the right side of the partition inside the main body of the collection box, and then start the double-shaft motor. When the double-shaft motor drives the first reciprocating screw to rotate, it can drive the synchronous rotation of the first bevel gear. Through the cooperation of the second bevel gear and the first bevel gear, the stirring shaft and the stirring rod are driven to rotate synchronously, and the liquid with puffer fish eggs is stirred, so as to facilitate the dispersion of fertilized eggs and prevent the accumulation of sticky fertilized fish.

[0038] Step 2: When the dual-axis motor drives the first reciprocating screw to rotate, the first reciprocating screw drives the transmission plate and the movable rod to reciprocate horizontally. When the movable rod drives the piston to move rightward inside the sealing tube, the liquid containing pufferfish eggs is sucked into the sealing tube through the cooperation of the first one-way valve and the conduit. When the piston moves to the left, the internal liquid is transported to the shunt pipe through the second one-way valve and flows into the filter box.

[0039] Step 3: The puffer fish egg mixed liquid flowing into the filter box is first filtered and separated from the larger impurities contained therein through the filter screen, and can be discharged through the first discharge port, and the puffer fish eggs and the remaining liquid fall into the lower part of the filter box for further filtration. The filter box with a smaller aperture can retain the fertilized eggs, and the driving pulley is driven to rotate while the dual-axis motor rotates. The active pulley, the driving belt and the driven pulley are cooperated to drive the movable disk and the limit rod to rotate synchronously, and the limit rod, the limit plate and the connecting rod are cooperated to drive the filter box to reciprocate horizontally back and forth during the rotation, thereby improving the filtering effect;

[0040] Step 4: While the filter box is reciprocating, the transmission gear is driven to rotate through the transmission rack. Due to the cooperation of the internal ratchet and the pawl, the transmission gear can only drive the one-way rotation of the second reciprocating screw, thereby driving the cleaning plate and the flexible bristles to reciprocate inside the filter box, cleaning the sticky fertilized eggs remaining inside the filter box, allowing them to fall into the guide groove through the second discharge port, and then be injected with clean water through the clean water pipe and flow out together with the fertilized eggs for collection.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows: the impurity-filterable puffer egg collection box and the collection method thereof can, by providing a stirring structure, disperse the puffer egg mixture, prevent the sticky fertilized eggs from agglomerating and piling up, and improve the dispersion of the fertilized eggs; and adopt a piston-type extraction structure, which can reduce the damage and loss to the fertilized eggs during the transportation of the puffer egg mixture; and at the same time, a reciprocating filtering structure is provided, which can filter both large and small impurities in the puffer egg mixture at the same time, and improve the filtering effect.

[0042] 1. By setting up two groups of filtering structures with different apertures, the larger impurities are filtered first, and then the fine impurities are filtered through the filter box, and the fertilized eggs are retained. The sticky fertilized eggs are cleaned by the reciprocating cleaning plate and flexible bristles, which is convenient for collection. At the same time, it can prevent the eggs from sticking to each other inside the filter box to cause blockage and reduce the activity during the water separation process, thereby ensuring the vitality and quality of the fertilized eggs;

[0043] 2. By setting a piston-type extraction structure, the puffer fish egg mixture can be extracted quantitatively and uniformly, and when the piston reciprocates inside the sealed tube, the puffer fish egg mixture is extracted intermittently, retaining the filtering time, preventing blockage or filtering effect caused by excessive flow, and the piston-type extraction structure is not easy to damage the fertilized eggs when extracting the puffer fish egg mixture, thereby ensuring the survival rate of the fertilized eggs and reducing the loss.

3. The method for collecting pufferfish eggs in a filterable impurity collecting box according to claim 2, characterized in that: The following steps are involved: Step 1: Pour the mixed liquid of puffer fish eggs collected after natural spawning into the right side of the internal partition (3) of the collection box body (1), and then start the double-axis motor (7). When the double-axis motor (7) drives the first reciprocating screw (8) to rotate, it can drive the first bevel gear (9) to rotate synchronously. Through the cooperation of the second bevel gear (11) and the first bevel gear (9), the stirring shaft (40) and the stirring rod (10) are driven to rotate synchronously, so as to stir the mixed liquid containing puffer fish eggs, so as to facilitate the dispersion of fertilized eggs and prevent the accumulation of sticky fertilized eggs. Step 2: while the dual-axis motor (7) drives the first reciprocating screw (8) to rotate, the first reciprocating screw (8) drives the transmission plate (16) and the movable rod (15) to reciprocate horizontally, and when the movable rod (15) drives the piston (14) to move rightward inside the sealing tube (12), the mixed liquid containing pufferfish eggs is sucked into the sealing tube (12) through the cooperation of the first one-way valve (13) and the guide tube (5), and when the piston (14) moves leftward, the internal liquid is transported to the shunt pipe (18) through the second one-way valve (17) and flows into the filter box (20); Step 3: The puffer fish egg mixture that flows into the filter box (20) is first filtered and separated from the larger impurities contained therein through the filter screen (24), and then discharged through the first discharge port (21). The fertilized eggs and the remaining liquid fall into the lower part of the filter box (20) for further filtration. The filter box (20) with a smaller aperture can retain the fertilized eggs. When the dual-axis motor (7) rotates, the driving pulley (25) is driven to rotate. Through the cooperation of the driving pulley (25), the transmission belt (27) and the driven pulley (26), the movable disk (28) and the limit rod (29) are driven to rotate synchronously. At the same time, through the cooperation of the limit rod (29), the limit plate (31) and the connecting rod (30), the filter box (20) is driven to reciprocate horizontally back and forth, thereby improving the filtering effect. Step 4: While the filter box (20) is reciprocating, the transmission gear (35) is driven to rotate through the transmission rack (36). Due to the cooperation between the inner ratchet (37) and the pawl (38), the transmission gear (35) can only drive the second reciprocating screw (41) to rotate in one direction, thereby driving the cleaning plate (33) and the flexible bristles (34) to reciprocate inside the filter box (20), cleaning the sticky fertilized eggs remaining inside the filter box (20), causing them to fall into the guide groove (23) through the second discharge port (22), and then be injected with clean water through the clean water pipe (43) and flow out together with the fertilized eggs for collection.
