Description

Technical Field

[0001] The utility model relates to the technical field of shrimp hatching and seedling raising, and more specifically, to a shrimp seed hatching device. Background Art

[0002] Shrimp is a type of crustacean arthropod with extremely high biodiversity and economic value. They are widely used in cooking various delicacies. At the same time, shrimp is also an important part of aquaculture. Many countries and regions are vigorously developing shrimp farming.

[0003] In shrimp farming, hatching and raising shrimp seedlings is essential. During hatching, shrimp seedlings are placed in incubators. Some eggs hatch quickly, while others hatch slowly. The small shrimp seedlings cannot be placed in ponds, causing the first-hatched shrimp seedlings to eat the eggs, resulting in losses for shrimp farming. In view of this, we propose a shrimp seedling incubator. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology, meet the actual needs, and provide a shrimp seed incubation device to solve the technical problem that the shrimp seed hatched first will swallow the shrimp eggs, causing losses to shrimp farming.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a shrimp seed hatching device, comprising an incubator and an oxygen supply mechanism and an incubation mechanism arranged in the incubator, wherein a mesh partition is installed in the incubator;

[0006] The oxygen supply mechanism includes an exhaust pipe and an air inlet pipe, wherein the exhaust pipe is installed on the inner wall of the bottom end of the incubator, an exhaust hole is opened at the upper end of the exhaust pipe, and the air inlet pipe is embedded in the side end of the incubator, and the end of the air inlet pipe is connected to the exhaust pipe;

[0007] A seedling raising chamber is formed between the hatching mechanism and the inner wall of the hatching box. The hatching mechanism includes a lower hatching tube and an upper hatching tube. The lower hatching tube is installed at the upper end of the mesh partition, and a shrimp egg partition is installed in the lower hatching tube. The upper hatching tube is plugged and installed at the upper end of the lower hatching tube. The side end of the upper hatching tube is provided with a separation port distributed in an array.

[0008] Preferably, slides distributed in an array are installed at the upper position of the side ends of the lower incubation tube, and the slides include arc-shaped plates, and the two side ends of the arc-shaped plates are integrally formed with side baffles extending upward. The side baffles are arc-shaped, and the width of the side baffles from the starting end to the end is set from wide to narrow.

[0009] Preferably, an array of escape openings are provided at the lower position of the side end of the upper incubation tube, and a cover plate is rotatably installed on the side end of the upper incubation tube above the escape opening. The cover plate is arranged in an arc shape, and the curvature of the cover plate is consistent with the curvature of the side baffle. The cover plate is arranged on the slide, and a wide channel and a narrow channel are formed between the cover plate and the slide, the wide channel is connected to the escape opening, and the narrow channel is directed towards the lower incubation tube.

[0010] Preferably, a positioning groove is provided at the upper end of the lower incubation tube between the slides, and a positioning plate is installed at the lower end of the upper incubation tube between the separation ports, and the positioning plate is plugged into the positioning groove.

DETAILED DESCRIPTION

[0022] like Figures 1 to 4 As shown, the present invention relates to a shrimp seed hatching device, comprising an incubator 101 and an oxygen supply mechanism 200 and an incubation mechanism 300 arranged in the incubator 101, wherein a mesh partition 102 is installed in the incubator 101;

[0023] The oxygen supply mechanism 200 includes an exhaust pipe 201 and an air inlet pipe 202. The exhaust pipe 201 is installed on the inner wall of the bottom end of the incubator 101. An exhaust hole is opened at the upper end of the exhaust pipe 201. The air inlet pipe 202 is embedded in the side end of the incubator 101. The end of the air inlet pipe 202 is connected to the exhaust pipe 201.

[0024] A nursery chamber 103 is formed between the hatching mechanism 300 and the inner wall of the incubator 101. The hatching mechanism 300 includes a lower hatching tube 301 and an upper hatching tube 305. The lower hatching tube 301 is mounted on the upper end of the mesh partition 102, and a shrimp egg partition 302 is installed in the lower hatching tube 301. The upper hatching tube 305 is plugged into the upper end of the lower hatching tube 301. The side ends of the upper hatching tube 305 are provided with an array of escape ports 306. By designing a new hatching structure, the present invention allows the shrimp fry to swim into the nursery chamber 103 after hatching, and makes it difficult for the shrimp fry to return to the hatching mechanism 300, preventing the shrimp fry from swallowing shrimp eggs and causing breeding losses.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, slide plates 303 arranged in an array are mounted on the upper side of the lower hatching tube 301. The slide plates 303 include curved plates 3031. Side baffles 3032 extending upward are integrally formed on both sides of the curved plates 3031. The side baffles 3032 are curved in shape, and the width of the side baffles 3032 is arranged from wide to narrow from the beginning to the end. The curved side baffles 3032, which are designed from wide to narrow, cooperate with the cover plate 307 to form a passage that is wide at the top and narrow at the bottom, making it difficult for shrimp seedlings in the nursery chamber 103 to enter the passage, thereby preventing the shrimp seedlings from re-entering the hatching mechanism 300 and ingesting the shrimp eggs.

[0026] Furthermore, an array of disengagement openings 306 are provided at the lower portion of the side end of the upper incubation tube 305. A cover plate 307 is rotatably mounted on the side end of the upper incubation tube 305 above the disengagement openings 306. The cover plate 307 is curved, and its curvature is consistent with that of the side baffle 3032. The cover plate 307 is mounted on the slide 303. A wide channel 308 and a narrow channel 309 are formed between the cover plate 307 and the slide 303. The opening of the narrow channel 309 is slightly larger than the size of the shrimp fry. The wide channel 308 is connected to the disengagement opening 306, and the narrow channel 309 faces the direction of the lower incubation tube 301. The narrow channel 309 is not located at the bottom of the nursery chamber, but faces the lower incubation tube 301, making it difficult for shrimp fry that have escaped from the incubation mechanism 300 to the nursery chamber 103 to re-enter the incubation mechanism 300.

[0027] It is worth noting that a positioning groove 310 is defined at the upper end of the lower incubation tube 301, located between the slides 303. A positioning plate 311 is installed at the lower end of the upper incubation tube 305, located between the release openings 306. The positioning plate 311 is inserted into the positioning groove 310. The positioning groove 310 and the positioning plate 311 are provided for the installation of the upper incubation tube 305, allowing the upper incubation tube 305 to be inserted and installed in the lower incubation tube 301.

[0028] It is worth mentioning that a positioning bar 304 is installed on the outer surface of the lower hatching tube 301 between the slides 303. The front end of the positioning bar 304 and the inner wall of the incubator 101 are provided with a plug-in slot, and the plug-in slot is plugged with a seedling partition 104, which is located in the seedling room 103. The positioning bar 304 and the plug-in slot are provided for the installation of the seedling partition 104, which can divide the seedling room 103 into six spaces, so that the farmers can separate the large and small shrimp seedlings for breeding.

[0029] Working principle: This embodiment provides a shrimp seed hatching device. When in use, oxygen is supplied through the air inlet pipe 202. The oxygen enters the exhaust pipe 201 and can be discharged from the exhaust hole into the incubator 101. The shrimp eggs are placed on the upper end of the shrimp egg partition 302 in the lower hatching tube 301. The height of the shrimp eggs is not higher than the escape port 306. When the shrimp eggs hatch into shrimp fry, as the shrimp fry move, they can enter the wide channel 308 from the escape port 306. The channel is set downward, so that the shrimp fry can swim out of the narrow channel 309 into the seedling chamber 103. The channel from the seedling chamber 103 to the hatching mechanism 300 is upward, the narrow channel 309 is not located at the bottom of the seedling chamber 103, and the narrow channel 309 is set toward the lower hatching tube 301, so that the shrimp fry can return to the hatching mechanism 300. In the seedling chamber 103, the seedling partition 104 can also be pulled out to connect the seedling chamber 103, so that the shrimp fry can swim freely in the seedling chamber 103.

[0030] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
