Description

Technical Field

[0001] This utility model belongs to the field of aquaculture equipment technology, specifically relating to a device for hatching and molting Artemia eggs. Background Technology

[0002] Artemia eggs, rich in protein and fat in their yolks, are excellent feed for fish and shrimp and are widely used in artificial breeding of fish and shrimp. However, because the outer shell of Artemia eggs is covered with bacteria, fungi, molds, and other harmful parasites, directly introducing them into the breeding pond can cause water pollution and harm aquatic animals. Furthermore, the outer shell of Artemia eggs contains ferritin, which fish and shrimp larvae cannot digest. Ingesting the eggshell and unhatched eggs can cause intestinal obstruction and death. Therefore, the outer shell of Artemia eggs must be removed before introducing them into the breeding pond.

[0003] The outer shell of Artemia eggs is mainly composed of lipoproteins and hemosiderin. These two substances can be oxidized by a certain concentration of hypochlorite, thus removing the outer shell. After shell removal, the Artemia eggs are left with only a transparent inner membrane, rich in yolk, and can be directly released into nursery ponds to feed fish, shrimp, and crabs, or they can hatch into nauplius larvae. Currently, the conventional technique for removing the outer shell of Artemia eggs involves placing the eggs in a container filled with hypochlorite and manually stirring them continuously to oxidize the hypochlorite with the lipoproteins and hemosiderin, thereby removing the outer shell. However, the oxidation reaction between hypochlorite and the egg shell generates a large amount of heat, causing the container temperature to become too high, which can easily lead to the death of many Artemia eggs and reduce the molting survival rate. Moreover, manual stirring consumes a lot of manpower and resources, increasing production costs and reducing economic efficiency. Therefore, it is necessary to design a device that can replace manual stirring to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for hatching and exfoliating Artemia eggs to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] A device for hatching and molting eggs of Artemia salina includes a mounting frame, which includes a base and a main arm that is vertically and fixedly connected to both sides of the base. A mounting plate is slidably mounted on the main arm, and a drive motor is fixedly mounted on the mounting plate.

[0007] The base is detachably equipped with a mixing tank, which contains a mixing mechanism for mixing water and a scraping mechanism for scraping off dirt from the inner wall of the mixing tank.

[0008] The output shaft of the drive motor is connected to a clutch mechanism, which is used to control the connection status between the output shaft of the drive motor and the stirring mechanism and the wall scraping mechanism.

[0009] As a further improvement, the stirring mechanism includes a stirring shaft, the bottom of which is rotatably connected to the bottom of the stirring tank, and the top of which is detachably connected to the output shaft of the drive motor.

[0010] The stirring mechanism also includes a fan blade, which includes multiple horizontally arranged support arms. The multiple support arms are evenly arranged along the axial direction of the stirring shaft. Each end of the multiple support arms is provided with a vertical connecting arm. The two ends of the support arms are fixedly connected to the corresponding connecting arms, and the center of the support arm is fixedly connected to the stirring shaft.

[0011] As a further improvement, the wall scraping mechanism includes multiple scrapers evenly distributed along the circumference. The sides of the multiple scrapers abut against and slide against the inner wall of the mixing tank. One end of the scraper is fixedly connected to a top cover, and the side wall of the top cover is rotatably connected to the inner wall of the mixing tank.

[0012] A radially extending positioning step is fixedly provided on the inner wall of the bottom of the mixing tank. A connecting ring is fixedly connected to the other end of the scraper. The bottom surface of the connecting ring abuts against and slides against the upper surface of the positioning step.

[0013] As a further improvement, the clutch mechanism includes a sliding sleeve, which is a cylindrical tubular structure, and a first keyway parallel to the axis is provided on the inner wall of the sliding sleeve.

[0014] A first flat key parallel to the axis is fixedly provided on the output shaft of the drive motor, and the first flat key is slidably connected to the first keyway;

[0015] A second flat key is fixedly provided on the upper side wall of the stirring shaft, and the second flat key is slidably connected to the first keyway.

[0016] As a further improvement, the top cover is provided with a through mounting hole, and the sliding sleeve passes through the mounting hole and cooperates with the stirring shaft. A vertical second keyway is provided through the inner wall of the mounting hole, and a third flat key is fixed on the outer wall of the bottom of the sliding sleeve. The third flat key and the second keyway are slidably connected.

[0017] As a further improvement, a hydraulic rod is provided on the base, with the output end of the hydraulic rod fixedly connected to the mounting plate and the other end of the hydraulic rod fixedly connected to the base.

[0018] As a further improvement, a positioning plate is fixedly installed on the base. The positioning plate has an arc that matches the outer wall of the mixing tank, and the concave surface of the positioning plate matches the outer wall of the mixing tank.

[0019] Due to the adoption of the above technical solution, the beneficial technical effects of this utility model are as follows:

[0020] This utility model provides a hatching device for Artemia eggs. By setting up a stirring mechanism and using a drive motor to drive the stirring shaft and fan blades to rotate, the agent in the stirring tank can be fully contacted with the Artemia eggs. This not only accelerates the hatching speed of the Artemia eggs and dissipates the heat inside the stirring tank, but also saves manpower and reduces labor intensity.

[0021] By setting up a wall scraping mechanism, a drive motor is used to rotate the scraper relative to the mixing tank, thereby cleaning the dirt adhering to the inner wall of the mixing tank.

[0022] By setting a clutch mechanism, the connection status of the output shaft of the drive motor with the stirring shaft and the top cover can be controlled respectively. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] like Figure 1-8 As shown, an Artemia molting and hatching device includes a mounting frame 1. The mounting frame 1 includes a base 101 and a main arm 102 that is vertically fixedly connected to both sides of the base 101. A mounting plate 2 is slidably mounted on the main arm 102, and a drive motor 3 is fixedly mounted on the mounting plate 2.

[0035] A mixing tank 4 is detachably mounted on the base 101. The mixing tank 4 is equipped with a mixing mechanism 5 for mixing water and a wall scraping mechanism 6 for scraping off dirt from the inner wall of the mixing tank 4.

[0036] The output shaft of the drive motor 3 is connected to a clutch mechanism 7, which is used to control the connection status between the output shaft of the drive motor 3 and the stirring mechanism 5 and the wall scraping mechanism 6.

[0037] During use, the mounting bracket 1 needs to be fixed to a sturdy support to prevent its position from changing arbitrarily. The drive motor 3 provides power to the stirring mechanism 5 and the wall scraping mechanism 6. In practice, the drive motor 3 can be used with a reducer to reduce its speed and prevent excessive speed from damaging the Artemia eggs.

[0038] When the clutch mechanism 7 connects the output shaft of the drive motor 3 to the stirring mechanism 5, the drive motor 3 drives the stirring mechanism 5 to operate. Artemia eggs and the prepared pesticide are poured into the stirring tank 4. The stirring mechanism 5 stirs the pesticide and Artemia eggs in the stirring tank 4, which not only ensures full contact between the pesticide and the Artemia, accelerating the oxidation of the Artemia shell, but also helps to dissipate heat from inside the stirring tank 4, improving the survival rate of the Artemia.

[0039] When the clutch mechanism 7 connects the output shaft of the drive motor 3 to the wall scraping mechanism 6, the drive motor 3 drives the wall scraping mechanism 6 to operate, scraping away the dirt on the inner wall of the mixing tank 4. In practice, a water outlet pipe and valve can be installed at the bottom of the mixing tank 4, which can not only discharge the molted Artemia eggs out of the tank, but also discharge the scraped dirt out of the tank after the dirt removal operation is completed, making it convenient to use.

[0040] In this embodiment, the stirring mechanism 5 includes a stirring shaft 501, the bottom of which is rotatably connected to the bottom of the stirring tank 4, and the top of which is detachably connected to the output shaft of the drive motor 3.

[0041] It also includes fan blades 502, which include multiple horizontally arranged support arms 5021. These support arms 5021 are evenly distributed along the axial direction of the stirring shaft 501. Each support arm 5021 has a vertical connecting arm 5022 at both ends. The ends of each support arm 5021 are fixedly connected to the corresponding connecting arm 5022, and the center of each support arm 5021 is fixedly connected to the stirring shaft 501. In actual use, the support arms 5021 and connecting arms 5022 are preferably cylindrical to prevent excessive sharp edges from damaging the Artemia eggs. To enhance the stirring effect, more than one fan blade 502 can be arranged along the circumference of the stirring shaft 501.

[0042] In this embodiment, the wall scraping mechanism 6 includes multiple scrapers 601 evenly distributed along the circumference. The side edges of the scrapers 601 abut against and slide against the inner wall of the mixing tank 4. A top cover 602 is fixedly connected to one end of each scraper 601, and the side wall of the top cover 602 is rotatably connected to the inner wall of the mixing tank 4. When the drive motor 3 drives the scrapers 601 to rotate relative to the inner wall of the mixing tank 4, the side edges of the scrapers 601 scrape off the dirt adhering to the inner wall of the mixing tank 4, keeping the inner wall of the mixing tank 4 clean.

[0043] During rotation, the scraper 601 forms a first virtual cylindrical profile with its rotation axis as the central axis and the vertical distance from the edge of the scraper 601 to the rotation axis as the radius.

[0044] During rotation, the fan blade 502 forms a second virtual cylindrical profile with the axis of the stirring shaft 501 as the central axis and the vertical distance from the edge of the connecting arm 5022 to the axis of the stirring shaft 501 as the radius.

[0045] The second virtual contour is located within the first virtual contour to prevent the fan blade 502 and the scraper 601 from interfering with each other.

[0046] A radially extending positioning step 401 is fixedly provided on the inner wall of the bottom of the mixing tank 4. A connecting ring 603 is fixedly connected to the other end of the scraper 601. The bottom surface of the connecting ring 603 abuts against and slides against the upper surface of the positioning step 401. The positioning step 401 is used to define the axial installation position of the scraping mechanism 6 relative to the mixing tank 4 and to provide force support for the scraping mechanism 6.

[0047] In this embodiment, the clutch mechanism 7 includes a sliding sleeve 701, which is a cylindrical tubular structure. The inner wall of the sliding sleeve 701 is provided with a first keyway 7011 parallel to the axis.

[0048] A first flat key 7012 parallel to the axis is fixedly provided on the output shaft of the drive motor 3, and the first flat key 7012 is slidably connected to the first keyway 7011. The sliding fit between the first flat key 7012 and the first keyway 7011 limits the axial displacement between the output shaft of the drive motor 3 and the sliding sleeve 701, and prevents relative rotation.

[0049] A second flat key 7013 is fixedly provided on the upper side wall of the stirring shaft 501, and the second flat key 7013 is slidably connected to the first keyway 7011. Figure 5 As shown, when the sliding sleeve 701 moves downward and the second flat key 7013 is engaged with the first keyway 7011, the sliding sleeve 701 connects the output shaft of the drive motor 3 and the stirring shaft 501 as a whole. The output power of the drive motor 3 can be transmitted to the stirring shaft 501, causing the stirring shaft 501 to rotate synchronously. When the sliding sleeve 701 moves upward and the second flat key 7013 is disengaged from the first keyway 7011, the drive motor 3 cannot drive the stirring shaft 501 to rotate.

[0050] In this embodiment, a mounting hole is provided through the top cover 602, and the sliding sleeve 701 passes through the mounting hole and cooperates with the stirring shaft 501. A vertical second keyway 7014 is provided through the inner wall of the mounting hole, and a third flat key 7015 is fixedly provided on the bottom outer wall of the sliding sleeve 701. The third flat key 7015 and the second keyway 7014 are slidably connected. After the sliding sleeve 701 is moved so that the third flat key 7015 and the second keyway 7014 are in the cooperating state, the output power of the drive motor 3 is transmitted to the top cover 602, and the output shaft of the drive motor 3 can drive the top cover 602 to rotate, thereby driving the wall scraping mechanism 6 to rotate.

[0051] In practice, threaded holes are provided through the side wall of the sliding sleeve 701, and positioning holes are provided at different heights on the output shaft of the drive motor 3. When the sliding sleeve 701 slides to the corresponding position, the sliding sleeve 701 and the output shaft of the drive motor 3 can be fastened with bolts to prevent the position of the sliding sleeve 701 relative to the output shaft of the drive motor 3 from changing arbitrarily.

[0052] In this embodiment, a hydraulic rod 8 is provided on the base 101. The output end of the hydraulic rod 8 is fixedly connected to the mounting plate 2, and the other end of the hydraulic rod 8 is fixedly connected to the base 101. When the hydraulic rod 8 extends, it causes the mounting plate 2 to move upward, which in turn causes the drive motor 3 to move upward, thereby raising the output axis of the drive motor 3 to a certain height, which facilitates moving the position of the mixing tank 4.

[0053] In this embodiment, a positioning plate 103 is fixedly installed on the base 101. The positioning plate 103 has an arc that matches the outer wall of the mixing tank 4, and the concave surface of the positioning plate 103 abuts against the outer wall of the mixing tank 4. The positioning plate 103 is used to position the mixing tank 4. In actual use, a positioning block 402 can be fixedly installed on the outer wall of the mixing tank 4, and the positioning block 402 can be fastened to the positioning plate 103 with bolts to fix the position of the mixing tank 4 and prevent the mixing tank 4 from changing position arbitrarily during the mixing process.

[0054] In this embodiment, the Artemia eggs and the prepared pesticide are poured into the mixing tank 4. The sliding sleeve 701 is slid downwards to connect with the stirring shaft 501, and the bolts on the sliding sleeve 701 are tightened. After starting the drive motor 3, the drive motor 3 drives the stirring shaft 501 to rotate. The stirring shaft 501 drives the fan blades 502 to stir the pesticide in the mixing tank 4, ensuring that the pesticide comes into full contact with the outer shell of the Artemia eggs and undergoes an oxidation reaction. This helps to accelerate the molting speed of the Artemia eggs and also dissipates the heat inside the mixing tank 4. After the Artemia eggs have molted, the valve at the bottom of the mixing tank 4 is opened to discharge the Artemia eggs to the designated location.

[0055] Move the position of the sliding sleeve 701 and connect the output shaft of the drive motor 3 to the top cover 602 of the wall scraping mechanism 6. The drive motor 3 drives the top cover 602 and the scraper 601 to rotate, which can scrape off the dirt attached to the inner wall of the mixing tank 4, saving time and effort.

[0056] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
