Abstract
Description
Technical Field
[0001] This utility model belongs to the field of grouper egg hatching technology, specifically relating to an improved grouper egg hatching device. Background Technology
[0002] As a high-value marine aquaculture species, grouper seedling cultivation technology has become a crucial link in the development of aquaculture. In artificial breeding, the egg incubation stage directly affects embryonic development quality and larval survival rate, representing a core bottleneck restricting large-scale production.
[0003] Traditionally, grouper hatching is carried out in net cages or cement ponds in still water, relying on natural water exchange. This method suffers from problems such as large fluctuations in dissolved oxygen levels (often below 5 mg / L) and water quality deterioration caused by the accumulation of dead eggs, resulting in a hatching rate generally below 40%. In addition, the static placement of fish eggs inside the hatching device can also easily lead to egg death, affecting the hatching rate of grouper. Utility Model Content

[0025] Reference Figure 1-3 The above describes an improved grouper egg hatching device, which includes a hatching chamber structure 1, a lifting structure 2 inside the hatching chamber structure 1, and a placement structure 3 slidably connected inside the lifting structure 2.
[0026] The placement structure 3 includes a feeding frame 301. Connecting rods 302 are provided on both sides of the top of the feeding frame 301. A sliding hole 303 is provided inside the connecting rod 302. A vibration spring 304 is provided on one side of the connecting rod 302. A water inlet 305 is provided at the bottom of the feeding frame 301. A water permeable plate 306 is provided on the inner wall of the feeding frame 301. The sliding hole 303 is slidably connected to the inner wall of the sliding rod 207. The vibration spring 304 is located between the connecting rod 302 and the placement frame 206. When it is necessary to incubate grouper eggs, the grouper eggs are placed on the top of the water permeable plate 306 at the top of the feeding frame 301, and then water is injected into the interior of the incubation chamber structure 1.
[0027] Furthermore, in the above technical solution, the incubation chamber structure 1 includes a shell 101, with transmission screws 102 rotatably connected to both sides of the shell 101. Guide strips 103 are provided on both sides of the inner wall of the shell 101, and a support column 104 is provided at the bottom of the inner wall of the shell 101. A water tank 105 is provided at the top of the support column 104, and a water outlet 106 is provided at the top of the water tank 105. When the motor is started, the motor drives the transmission screws 102 to rotate, the transmission screws 102 drive the support bar 201 to move upward, the support bar 201 drives the side bar 204 to move upward, the side bar 204 drives the placement frame 206 to move upward, and the placement frame 206 drives the placement structure 3 to move upward during the upward movement.
[0028] Furthermore, in the above technical solution, the lifting structure 2 includes a support bar 201 and a placement frame 206. One end of the support bar 201 is provided with a vertical rod 202. The bottom of one end of the vertical rod 202 is provided with a mating hole 203, which is mated with the transmission screw 102. The vertical rod 202 is slidably connected to the housing 101. The other end of the support bar 201 is provided with a side rod 204. Both ends of the side rod 204 are provided with spring telescopic rods 205.

The insertion hole 208 is engaged with the spring telescopic rod 205. Then, the spring rod 207 is pushed inward and then released. The spring rod 207 is inserted into the insertion hole 208 at the top of the placement frame 206 to fix the material feeding frame 301 placed inside the placement frame 206.
[0029] The feeding frame 301 moves upward, causing its outer wall to pass through the guide strips 103 in sequence. The outer wall of the guide strips 103 is set with multiple arcs, and the guide strips 103 on both sides of the housing 101 are staggered, allowing the feeding frame 301 to move left and right. The sliding hole 303 slides on the outer wall of the sliding rod 207 and squeezes and stretches the vibration springs 304 at different positions, causing the feeding frame 301 to vibrate. The vibration can change the position of the grouper eggs. At the same time, the air pump is activated, which can draw water in and spray it out through the water outlet 106, allowing the water outlet 106 to move the grouper eggs through the water inlet 305 and the permeable plate 306 to simulate water flow. The permeable plate 306 is made of gauze or other water-permeable materials.
