Description

Technical Field

[0001] The invention relates to the technical field of fish breeding, in particular to a Qinling salmon egg hatching device. Background Art

[0002] The Qinling Slender-scaled Salmon belongs to the family Salmonidae in the order Salmoniformes, commonly known as splendid fish and flower fish. It is a national second-level key protected animal unique to my country. It is currently only distributed in the mountain streams in the upper reaches of the Weihe River and its tributaries in the Qinling Mountains and the upper reaches of the Weihe River and Ziwu River, tributaries of the north side of the Han River. Its habitat is above 1,000 meters above sea level.

[0003] The distribution range of Qinling salmon is narrow, and the habitat environment has been increasingly degraded in recent years, resulting in the fragmentation of the distribution area of ​​the population and a sharp decrease in the amount of wild resources. It is urgent to carry out protection actions to promote the recovery of its natural population. At present, the application of artificial breeding and fertilized egg hatching technology of Qinling salmon is an important way to protect the germplasm resources of this species under human intervention. Through years of practical exploration, researchers have found that the use of technical methods such as artificial regulation can optimize the processes of broodstock cultivation, synchronous development of male and female gonads, and artificial hatching of fertilized eggs, ensure the smooth progress of artificial breeding, and effectively improve the survival rate, fertilization rate, and hatching rate of domestication, which has positive significance for the maintenance of Qinling salmon germplasm resources and the recovery of wild populations.

[0004] The embryonic development and hatching rate of Qinling salmon fertilized eggs are greatly affected by environmental factors, mainly water temperature, dissolved oxygen, light and pathogenic microorganisms. Therefore, the refined management of the hatching process is the key technology to improve the hatching rate. When the Qinling salmon eggs are hatched, the hatching pool is usually used for running water hatching. There are certain requirements for water temperature and dissolved oxygen when hatching fish eggs. The water temperature environment needs to be between 8℃ and 10℃, and the dissolved oxygen content must be higher than 6.5mg / L. In this way, it can be successfully hatched after about a month of incubation time.

[0005] Qinling salmon eggs are sinking eggs. During the incubation period, the eggs are laid flat in the incubation pond. The entire incubation process needs to be carried out in the dark. The eggs will die when exposed to light. Normal fertilized eggs are light yellow. Dead eggs and unfertilized eggs are inevitable during the development process for various reasons. They are generally white and need to be removed to prevent them from remaining in the incubation water to breed a large number of bacteria or harmful substances, thereby affecting the activity of the eggs.

[0006] Since the incubation process of Qinling salmon eggs needs to be carried out under dark conditions, the traditional method of removing dead eggs and cleaning impurities by manual adsorption and separation through a straw is limited to the dark environment. Some traditional automated separation structures of fish eggs on the market combine visual recognition and screening, use visual recognition to identify the difference in color between live eggs and dead eggs, and then use an adsorption structure to suck out the dead eggs. This automatic separation method also has certain requirements for lighting during the identification process, and it is difficult to adapt to the dark incubation environment of Qinling salmon eggs. During the identification, there will be problems such as inaccurate identification due to the influence of light. In addition, during the incubation period of Qinling salmon eggs, the eggs are close to each other, making it difficult to directly remove a single identified egg, and the removal process is likely to cause damage or even death to the surrounding eggs. Summary of the invention

[0031] Example

[0032] like Figures 1 to 8 As shown, an embodiment of the present invention provides a Qinling salmon egg hatching device, comprising a hatching basket 2 slidably connected to a hatching pool 1, wherein the bottom and surrounding of the hatching basket 2 are provided with water permeable holes.

[0033] Among them, the side walls of the hatching pool 1 are respectively connected with a water injection pipe 101 and a drainage pipe 102, and stream water and deep spring water can be introduced into the hatching pool 1 through the water injection pipe 101 to provide a good water environment suitable for the hatching of Qinling salmon eggs, so that the water temperature is maintained at a temperature suitable for the hatching of Qinling salmon. The drainage pipe 102 is connected to the external circulation pump structure to achieve the purpose of circulating water in the hatching pool 1. At the same time, in order to separate the dead eggs and impurities produced during the hatching process of the fish eggs, it also includes a water flow disturbance mechanism, a lifting mechanism, a high-pressure water flow impact component and an isolation component; the water flow disturbance mechanism includes a rotary drive component, a rotating shaft 31 and a spiral blade 32, the rotary drive component is arranged on the outer wall of the hatching basket 2, the rotating shaft 31 is vertically arranged, and one end of the rotating shaft 31 is connected to the output end of the rotary drive component The spiral blade 32 is connected to the circumference of the rotating shaft 31. The rotating shaft 31 drives the spiral blade 32 to rotate under the drive of the rotary drive component to achieve water disturbance around the hatching basket 2, so that the live eggs and dead eggs and floating debris inside the hatching basket 2 are dispersed; the lifting mechanism has a mobile lifting end, and the mobile lifting end is connected to the hatching basket 2, which is used to drive the hatching basket 2 to be lifted and lowered along the height direction of the hatching pool 1. When the hatching basket 2 is driven to descend, the hatching basket 2 is descended at a speed greater than the sinking speed of the dead eggs and the live eggs; the high-pressure water flow impact component is arranged on one side of the inside of the hatching pool 1; the isolation component is arranged in the hatching pool 1 and is located on the opposite side of the high-pressure water flow impact component. The isolation component includes an isolation chamber and an opening and closing component. The isolation chamber is connected to the inside of the hatching pool 1, and the opening and closing component is arranged at the connection between the isolation chamber and the hatching pool 1.

[0034] In the present embodiment, when the eggs of Qinling salmon are hatched, the whole device is placed in a lightless environment for hatching. It is only necessary to lay the Qinling salmon eggs to be hatched in the hatching basket 2, and inject water into the hatching pool 1 through the water injection pipe 101 for hatching. When it is necessary to clean the dead eggs and impurities generated during the hatching process, the water flow is first disturbed by the set water flow disturbance mechanism. Specifically, the spiral blade 32 is driven by the rotating drive component to rotate, and the water flow around the hatching basket 2 is spirally stirred. The stirred water flow can pass through the water permeable holes and then turn over the eggs in the hatching basket 2, which not only disperses and separates the live eggs, impurities and dead eggs, but also achieves the purpose of increasing dissolved oxygen. Then the lifting mechanism is controlled to quickly drive the hatching basket 2 to move downward to the bottom of the dead egg collecting mechanism. The speed of the hatching basket 2 moving downward is greater than the sinking speed of the dead eggs and the live eggs, so that the hatching basket 2 no longer provides support for the dead eggs and the live eggs. Since Qinling salmon are sinking eggs, the dead eggs and the live eggs will gradually sink. The hatching basket 2 is a kind of hatching basket 2, which is composed of a plurality of living eggs, and a plurality of living eggs, and a plurality of dead eggs, and a plurality of living eggs, and a plurality of dead eggs, are hatched and gradually sink. Since the metabolic activity inside the living eggs is normal, they contain more water and nutrients, while the dead eggs have lost their vitality, and their internal chemical composition and physical state may gradually change, resulting in protein denaturation, water loss, etc. Compared with dead eggs, living eggs have greater buoyancy, which slows down their sinking speed, while dead eggs will sink to the bottom first. When the hatching basket 2 moves downward to the bottom of the high-pressure water flow impact component, the opening and closing component will be triggered to open the isolation chamber. Under the high-pressure water flow ejected by the high-pressure water flow impact component, the dead eggs that sink first will be ejected into the isolation chamber. When the hatching basket 2 rises and passes over the high-pressure water flow impact component, the opening and closing component will be triggered to close the isolation chamber to isolate the dead eggs. The rising hatching basket 2 will receive the live eggs that sink subsequently, and then slowly rise to the position close to the pool surface for subsequent hatching process. In this way, the process of regularly cleaning the eggs of Qinling fine-scale salmon in the dark can be automatically realized, and the problem of damaging the eggs of Qinling fine-scale salmon will not be caused.

[0035] Specifically, as an implementation method of the lifting mechanism, the lifting mechanism in this embodiment includes a pair of parallel scissor-type telescopic frames and a spacing adjustment component. The scissor-type telescopic frame includes multiple groups of connecting rod assemblies 41 and support plates 44. The multiple groups of connecting rod assemblies 41 are stacked up and down, and each group of connecting rod assemblies 41 includes two connecting rods that are hinged in the middle and form an X shape with each other. The ends of the connecting rods in the upper and lower adjacent connecting rod assemblies 41 are hinged to each other, and the lower ends of the two connecting rods in the connecting rod assembly 41 located at the bottom correspond to the tops of the two first sliders 42, respectively. The upper ends of the two connecting rods in the upper connecting rod assembly 41 are respectively hinged to the bottom of the two second sliders 43; the support plate 44 is arranged above the two second sliders 43, and the bottom of the support plate 44 is provided with a slide groove 441 along its length direction. The tops of the two second sliders 43 are slidably connected in the slide groove 441, and the top of the support plate 44 is connected to the side wall of the hatching basket 2. The spacing adjustment assembly is connected between the two first sliders 42, and is used to adjust the spacing between the two first sliders 42 to change the opening angle of the connecting rod assembly 41, so as to drive the support plate 44 to move up and down.

[0036] In the present embodiment, when the lifting mechanism is used to drive the support plate 44 to move up and down, the two first sliders 42 in the two groups of scissor-type telescopic frames are controlled by controlling the spacing adjustment component to move closer to or farther away from each other to change their spacing. During the movement of the two first sliders 42 in the scissor-type telescopic frame, the opening angles of the two connecting rods in the lowermost connecting rod assembly 41 that are hinged in the middle and form an X shape with each other are squeezed. Since the ends of the connecting rods in the two adjacent upper and lower connecting rod assemblies 41 are hinged to each other, the opening angles of each connecting rod assembly 41 are changed synchronously, and the support plate 44 and the incubation frame 2 are driven to move up and down by sliding with the two second sliders 43 in the uppermost connecting rod assembly 41. When the opening angle of the connecting rod assembly 41 is reduced, the support plate 44 is driven to rise, and when the opening angle of the connecting rod assembly 41 is increased, the support plate 44 is driven to fall.

[0037] Furthermore, in order to prevent the second slider 43 from easily falling out of the slide groove 441 when sliding driven by the connecting rod, the cross-sectional shape of the slide groove 441 is set to a T-shape or a dovetail shape, and the shape of the second slider 43 matches the slide groove 441. Through the above setting, the longitudinal locking of the second slider 43 and the slide groove 441 is achieved to ensure that the second slider 43 will not fall out of the slide groove 441.

[0038] Specifically, as an implementation of a spacing adjustment component, the spacing adjustment component in this embodiment includes a first motor 51, two bidirectional lead screws 52 and a synchronous belt transmission mechanism; the first motor 51 is arranged on the outside of the incubation pool 1; the two bidirectional lead screws 52 are arranged horizontally and in parallel, one end of one bidirectional lead screw 52 is connected to the output shaft of the first motor 51, and the other ends of the two bidirectional lead screws 52 extend into the incubation pool 1 and are rotatably connected to the inner wall of the incubation pool 1, and the two first sliders 42 in each scissor-type telescopic frame are nut seats, and are respectively correspondingly sleeved and connected to the two sides of each bidirectional lead screw 52; the synchronous belt transmission mechanism is connected between the two bidirectional lead screws 52, wherein the synchronous belt transmission mechanism includes two synchronous pulleys 53 and a synchronous belt 54, the two synchronous pulleys 53 are respectively fixed on the two bidirectional lead screws 52, and are arranged close to the first motor 51, and the two synchronous pulleys 53 are connected by a synchronous belt 54.

[0039] In this embodiment, when the spacing adjustment component is used to adjust the spacing between the two first sliders 42 in the two sets of scissor-type telescopic frames, the first motor 51 is controlled to drive the bidirectional lead screw 52 connected thereto to rotate. When the bidirectional lead screw 52 rotates, the transmission of the synchronous belt transmission mechanism will drive another bidirectional lead screw 52 to rotate synchronously. In the process of the synchronous rotation of the two bidirectional lead screws 52, the two first sliders 42 connected thereto are driven to move away from each other or closer to each other.

[0040] Specifically, as an implementation manner of a rotation drive component, the rotation drive component in this embodiment includes multiple support springs 33, a first lead screw 34, a first nut seat 35 and a limit plate 36; multiple support springs 33 are arranged on the outside of the rotating shaft 31 and are arranged along the length direction of the support plate 44, and the mounting frame plate 21 is fixed on the side walls around the opening of the hatching basket 2, and multiple support springs 33 are connected between the support plate 44 and the mounting frame plate 21, and the upper end of the rotating shaft 31 is rotatably connected to the mounting frame plate 21; the first lead screw 34 is arranged parallel to one side of the rotating shaft 31, and the upper end of the first lead screw 34 is rotatably connected to the mounting frame plate 21, and the first lead screw 34 is connected to the rotating shaft 31 through a gear transmission mechanism; the first nut seat 35 is fixed on the side wall of the support plate 44 and is located directly below the first lead screw 34, and the lower end of the first lead screw 34 is connected to the first nut seat 35; the limit plate 36 is fixed on the inner wall of the hatching pool 1 near its pool mouth.

[0041] In this embodiment, the driving power of the rotary drive assembly is realized with the aid of a lifting mechanism. When the lifting mechanism drives the support plate 44 to rise, due to the presence of multiple support springs 33, an elastic supporting force will be generated on the mounting frame plate 21, thereby driving the mounting frame plate 21 and the incubation frame 2 to rise synchronously. When the mounting frame plate 21 moves to contact with the limit plate 36, it is limited and will not rise. As the lifting mechanism continues to rise, the support plate 44 will squeeze the multiple support springs 33 and make the first nut seat 35 rise synchronously to squeeze the first lead screw 34, so that the first lead screw 34 itself rotates. During the rotation of the first lead screw 34, the gear transmission mechanism drives the rotating shaft 31 to rotate, thereby driving the spiral blade 32 to rotate to achieve the disturbance process of the water flow.

[0042] Furthermore, an arcuate guide surface 211 for guiding the sinking fish eggs into the hatching basket 2 is provided on the top of the mounting frame 21, and a layer of flexible buffer pad is provided on the surface of the arcuate guide surface 211. Through the above arrangement, when the hatching basket 2 is driven up by the lifting mechanism to receive the sinking live eggs, the arcuate guide surface 211 provided on the mounting frame 21 can be used to collect and guide the fish eggs close to the wall of the hatching pool 1 into the hatching basket 2. Since a layer of flexible buffer pad is provided on the surface of the arcuate guide surface 211, it can play a buffering role when receiving the live eggs to avoid damage to the live eggs caused by impact.

[0043] Furthermore, in order to achieve a sealed installation of the gear transmission mechanism, a sealed installation cavity 212 is provided inside the installation frame plate 21, and the upper end of the rotating shaft 31 and the upper end of the first lead screw 34 both extend into the sealed installation cavity 212 and are rotatably connected to the top of the sealed installation cavity 212, and the gear transmission mechanism is arranged in the sealed installation cavity 212, wherein the gear transmission mechanism includes a driving gear 37 and a driven gear 38 that mesh with each other, the driving gear 37 is fixedly mounted on the upper end of the first lead screw 34, and the driven gear 38 is fixedly mounted on the upper end of the rotating shaft 31.

[0044] Specifically, Figure 2 , Figure 6 and Figure 7 As shown, the high-pressure water flow impact component includes a booster pump 61, a multi-way pipe 62 and a plurality of nozzles 63. The booster pump 61 is fixed on the outer wall of the hatching pool 1, and the multi-way pipe 62 is arranged in a mounting groove 11 horizontally opened on the inner wall of the hatching pool 1. The multi-way pipe 62 has an input port and a plurality of output ports arranged along its length direction. The input port is connected to the output end of the booster pump 61, and the plurality of nozzles 63 are connected to the plurality of output ports in a one-to-one correspondence. The input end of the booster pump 61 is connected to an external water source through a water diversion pipe 611. In order to increase the shooting range, the plurality of nozzles 63 can be arranged in multiple rows to ensure that no dead eggs are missed.

[0045] Further, such as Figure 6As shown, the isolation chamber is an isolation box 64, which is fixed on the outer wall of the incubation pool 1. The isolation box 64 is connected to the incubation pool 1, and the opening and closing assembly includes an interception mesh plate 65, a hinge shaft 66 and a reset spring 67. The interception mesh plate 65 is tiltedly arranged inside the isolation box 64, and the lower side of the interception mesh plate 65 is hinged to the inner wall of the isolation box 64 through the hinge shaft 66, and the higher side end of the interception mesh plate 65 extends into the incubation pool 1, and the top surface of the interception mesh plate 65 is connected to the inner top surface of the isolation box 64 through the reset spring 67.

[0046] When the dead eggs that sink first are isolated and collected, as the lifting mechanism drives the hatching basket 2 to move downward, the hatching basket 2 drives the mounting frame plate 21 to move downward and presses down the highest end of the interception mesh plate 65, so that the interception mesh plate 65 rotates around the hinge shaft 66 and stretches the reset spring 67. After the hatching basket 2 moves to the bottom of the multiple nozzles 63, the interception mesh plate 65 is flipped to open an opening at a certain angle, and the booster pump 61 in the high-pressure water flow impact assembly draws in external water flow through the water diversion pipe 611 and pressurizes and delivers it to the multi-channel pipe 62, and are ejected through multiple nozzles 63, so that the sunken dead eggs are rushed to the opening and fall into the separation chamber formed by the interception mesh plate 65 and the inner wall of the isolation box 64. After being collected for a certain period of time, the lifting mechanism drives the hatching basket 2 and the mounting frame plate 21 to move upward, and the mounting frame plate 21 no longer exerts pressure on the interception mesh plate 65. Therefore, under the elastic force of the reset spring 67, the interception mesh plate 65 returns to its original position, and the opened opening is automatically closed, so that the collected dead eggs are separated and stored in the isolation box 64.

[0047] Among them, in order to facilitate the discharge of isolated dead eggs, an ovipositor tube 641 is connected to the side wall of the isolation box 64 facing away from the high-pressure water flow impact component. A sealing cover is threadedly connected to the ovipositor tube 641, which is usually closed. When discharging, the sealing cover is opened to discharge the dead eggs that have slipped to the bottom of the interception mesh plate 65 through the ovipositor tube 641.

[0048] In another embodiment of the present invention, in order to be able to remove some floating impurities generated when dead eggs and live eggs are dispersed, a floating object adsorption mechanism is also provided, which includes a linear motion component, a dirt suction hood 71, a dirt suction pump 72, a bellows 73, a sewage pipe 74 and a filter barrel 75; the linear motion component is arranged at the pool mouth of the hatching pool 1; the dirt suction hood 71 is connected to the moving end of the linear motion component, and moves horizontally along the pool mouth of the hatching pool 1 driven by the linear motion component; the dirt suction pump 72 is fixed on the outer wall of the hatching pool 1; one end of the bellows 73 is connected to the output end of the dirt suction pump 71, and the other end of the bellows 73 is connected to the dirt suction hood 71.

[0049] Through the above arrangement, during the sinking of dead eggs and live eggs, the floating object adsorption mechanism arranged at the pool mouth can be used to adsorb and collect the scattered floating impurities. When adsorbing floating objects, the sewage suction pump 72 is started, and the sewage suction cover 71 can be driven to move and adsorb while being moved through the arranged linear moving component. The arranged bellows 73 has a telescopic function, which is convenient for changing its own length along with the movement of the sewage suction cover 71 to keep conveying at all times. The sewage suction pump 72 discharges the sewage mixed with impurities sucked up through the sewage discharge pipe 74 into the filter barrel 75 for filtration and collection.

[0050] The linear motion assembly includes a second motor 81, a first transmission gear 82, a second transmission gear 83, a second lead screw 84, a slide column 85, a moving block 86 and a connecting rod 87. The second motor 81 is fixed to the outer wall of the incubation pool 1, and the output shaft of the second motor 81 is connected to the first transmission gear 82. The second lead screw 84 and the slide column 85 are parallelly arranged on both sides of the top of the pool mouth of the incubation pool 1.
