Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a temperature-controlled incubation device for Artemia worms. Background Technology

[0002] Artemia, as an important aquatic food organism, is widely used in the aquaculture industry. Its hatching efficiency and quality directly affect the growth and development of subsequent aquatic organisms. Therefore, efficient and stable Artemia hatching devices are crucial for the aquaculture industry. Traditional Artemia hatching methods are relatively crude, mostly simply placing Artemia eggs in a water-filled container and relying on natural environmental conditions for hatching. However, Artemia eggs have a certain weight and tend to sink and aggregate in the hatching solution. Once a large number of eggs sink to the bottom, they will pile up, which not only reduces the contact area between the eggs and the hatching solution and restricts dissolved oxygen exchange, but also leads to uneven temperature distribution in the environment where the eggs are located. For example, eggs near the bottom of the container often fail to reach the ideal hatching temperature due to relatively slow heat transfer, greatly reducing the hatching success rate. Current temperature-controlled hatching equipment does not have a corresponding anti-sinking mechanism and relies only on simple manual observation, which cannot guarantee that the eggs can receive uniform heat. Utility Model Content

[0003] In view of this, the present invention proposes a temperature-controlled incubation device for Artemia salina, which can prevent Artemia salina eggs from sinking to the bottom, ensure that the eggs are heated evenly, and improve the hatching rate.

[0004] The technical solution of this utility model is implemented as follows:

The heating plate is disposed on the inner side wall and bottom surface of the incubation box. The motor is disposed on the top surface of the incubation box, and its output shaft extends into the incubation box and connects to the top of the rotating shaft. The blades are disposed on the outer wall of the rotating shaft. The pushing mechanism includes a sleeve, a piston, a return spring, a force-bearing block, a pushing rod, a horizontal tube, a vertical tube, and air jets. The sleeve is embedded in the side wall of the incubation box, and an air inlet is disposed on the side of the sleeve located outside the incubation box.

The return spring connects the side wall of the piston and the inner side wall of the sleeve. The force-bearing block is connected to the side wall of the piston, and its outer wall is slidably connected to the inner wall of the sleeve. The pushing rod is disposed on the side wall of the rotating shaft, and the force-bearing block is located on the rotation path of the pushing rod. The horizontal tube is disposed on the bottom surface of the incubation box, and one end of it extends outside the incubation box. The vertical tube connects the end of the horizontal tube located outside the incubation box and the bottom surface of the sleeve. The air jets are spaced apart on the top surface of the horizontal tube.

[0006] Preferably, the inner wall of the sleeve is provided with a sliding groove that extends to the end of the sleeve, and the outer wall of the force-bearing block is provided with a slider that is located in the sliding groove.

[0011] Preferably, it also includes support feet, which are disposed on the bottom surface of the incubator.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] ① After pouring the brine shrimp eggs to be hatched and the hatching solution into the hatching box, the hatching solution can be heated by the heating plate. At the same time, the motor can drive the blades to rotate through the shaft to achieve uniform stirring of the hatching solution, so that the heating is uniform and a suitable hatching environment is provided for the brine shrimp eggs.

[0014] ② When the shaft rotates, the push rod can push the force block to move, so that after the piston is pushed, the air in the sleeve is pushed into the vertical pipe. Finally, the air can be ejected from the horizontal pipe and the jet nozzle, which can not only increase the dissolved oxygen content in the incubation solution, but also form an upward water flow at the bottom of the incubation box, preventing the brine shrimp eggs from sinking to the bottom, improving the uniform heating of the brine shrimp eggs, and increasing the hatching rate.

Detailed Implementation

[0020] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0021] See Figs. 1 to 3 This utility model provides a temperature-controlled incubation device for Artemia worms, comprising an incubation box 1, a heating plate 2, a motor 3, a rotating shaft 4, blades 5, and a pushing mechanism. The heating plate 2 is disposed on the inner side wall and inner bottom surface of the incubation box 1. The motor 3 is disposed on the top surface of the incubation box 1, and its output shaft extends into the incubation box 1 and connects to the top of the rotating shaft 4. The blades 5 are disposed on the outer wall of the rotating shaft 4. The pushing mechanism includes a sleeve 6, a piston 7, a return spring 8, a force-bearing block 9, a pushing rod 10, a horizontal tube 11, a vertical tube 12, and a jet nozzle 13. The sleeve 6 is embedded in the side wall of the incubation box 1, and a [missing information - likely a component or part] is disposed on the side outside the incubation box 1. Air inlet 14; sleeve 6 is located on one open side inside incubator 1; piston 7 is located inside sleeve 6; return spring 8 connects the side wall of piston 7 and the inner side wall of sleeve 6; force block 9 is connected to the side wall of piston 7, and its outer wall is slidably connected to the inner wall of sleeve 6; push rod 10 is located on the side wall of rotating shaft 4; force block 9 is located on the rotation path of push rod 10; horizontal tube 11 is located on the bottom surface inside incubator 1, with one end extending outside incubator 1; vertical tube 12 connects the end of horizontal tube 11 outside incubator 1 and the bottom surface of sleeve 6; air nozzles 13 are spaced apart on the top surface of horizontal tube 11.

[0022] The incubator 1 is made of transparent material. During incubation, the brine shrimp eggs and incubation solution are poured into the incubator 1. After turning on the heating plate 2, the incubation solution can be heated, thus providing a suitable temperature environment for the incubation of brine shrimp eggs. During the incubation process, the motor 3 can be started, which can drive the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the blades 5 on its outer wall can stir the incubation solution, so that the brine shrimp eggs are evenly distributed and the position of the incubating eggs can be changed so that they can fully contact the incubation solution.

[0023] A push rod 10 is also installed on the rotating shaft 4. The push rod 10 can rotate synchronously with the rotating shaft 4. During the rotation, it will contact the force block 9 and push the force block 9 to drive the piston 7 into the sleeve 6. When the piston 7 moves in the sleeve 6, it will squeeze air from the vertical pipe 12 into the horizontal pipe 11. Several air nozzles 13 are installed on the horizontal pipe 11. The air nozzles 13 can spray air into the hatching liquid to increase the dissolved oxygen content. At the same time, the air spray will form an upward water flow, pushing the hatching eggs upward and preventing them from sinking to the bottom, so that the Artemia eggs can better receive heat and improve the hatching survival rate. In addition, when the push rod 10 leaves the force block 9, under the action of the return spring 8, the piston 7 can drive the force block 9 to move to the outside of the sleeve 6 for reset. The air port 14 can allow external air to enter the sleeve 6 for the next air spray.

[0024] There are multiple horizontal tubes 11, which can form a uniform upward water flow in the incubation box 1, thereby avoiding blind spots that would cause some Artemia eggs to sink to the bottom.

[0025] Preferably, the inner wall of the sleeve 6 is provided with a sliding groove 15, the sliding groove 15 extends to the end of the sleeve 6, and the outer wall of the force-bearing block 9 is provided with a slider 16, the slider 16 being located in the sliding groove 15.

[0026] The slide groove 15 is provided on both sides of the sleeve 6, and the slider 16 is also provided on both sides of the force-bearing block 9. When the force-bearing block 9 is moved by an external force, the slider 16 can move along the slide groove 15 to ensure that the force-bearing block 9 will not deviate when it moves, and to ensure that the push rod 10 can push the force-bearing block 9 to move along the sleeve 6.

[0027] Preferably, the pushing mechanism further includes an air intake pipe 17 and a solenoid valve 18. The air intake pipe 17 is disposed outside the air inlet 14, and the solenoid valve 18 is disposed on the air intake pipe 17.

[0028] Solenoid valve 18 can control the opening and closing of air intake pipe 17. When jet injection is required, solenoid valve 18 can close air intake pipe 17 to prevent air in sleeve 6 from being discharged from air port 14. After push rod 10 leaves force block 9, solenoid valve 18 can open to open air intake pipe 17 so that external air can enter sleeve 6.

[0029] Preferably, the pushing mechanism further includes a battery pack 19 and a normally open button 20. The battery pack 19 is disposed on the outer wall of the incubator 1, and the normally open button 20 is disposed in the slide groove 15 and located on the moving path of the slider 16. The battery pack 19, the normally open button 20 and the solenoid valve 18 form a circuit.

[0030] The solenoid valve 18 of this utility model is a normally open solenoid valve. It is normally open when not energized. When the push rod 10 contacts the force block 9 and pushes the force block 9 to move, the slider 16 can move along the slide groove 15. During the movement, it will contact the normally open button 20 to trigger it. The normally open button 20 becomes closed. At this time, the solenoid valve 18 is energized and closes, ensuring that the air in the sleeve 6 can enter the horizontal pipe 11 only from the vertical pipe 12. When the push rod 10 leaves the force block 9, the slider 16 will reset and leave the normally open button 20. When the normally open button 20 returns to the open state, the solenoid valve 18 opens after losing current. At this time, external air can enter the sleeve 6 from the air inlet pipe 17 and the air port 14, waiting for the next jet process.

[0031] Preferably, it also includes a connecting rod 21, which connects the side wall of the force-bearing block 9 and the side wall of the piston 7.

[0032] The connecting rod 21 is used to connect the piston 7 and the force block 9 so that the force block 9 can push the piston 7 to move.

[0033] Preferably, the side wall of the force-bearing block 9 away from the connecting rod 21 is provided with an arc-shaped part 22, and the arc-shaped part 22 is located on the rotation path of the push rod 10.

[0034] During the rotation of the push rod 10, it will come into contact with the arc-shaped part 22. The arc-shaped part 22 allows the push rod 10 to easily push the force block 9 to move horizontally along the sleeve 6.

[0035] Preferably, it also includes a support foot 23, which is disposed on the bottom surface of the incubator 1.

[0036] The support feet 23 are provided to support the incubator 1, ensuring that the stirring and air jetting processes can be carried out stably.
