Description

Technical Field

[0001] This utility model relates to the field of redclaw crayfish farming technology, specifically to a redclaw crayfish seedling sorting pond. Background Technology

[0002] Redclaw crayfish, also known as Australian freshwater crayfish, is native to Australia. Resembling a marine lobster, it is one of the world's most prized freshwater shrimp species. Its body is brownish-green, and males have a bright red membranous band at the tip of their claws, making it beautiful and hence the name "redclaw crayfish." In redclaw crayfish farming, to improve the survival rate of larvae, they are usually raised in specialized nursery ponds. Once they reach a certain size, they are transferred to normal rearing ponds. However, current techniques often involve concentrated rearing of larvae in nursery ponds, leading to differences in growth. Larger larvae may cannibalize smaller ones, affecting their normal growth. Therefore, a redclaw crayfish larvae sorting pond is proposed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problem that shrimp larvae are usually raised in a concentrated manner in seedling ponds, and there will be differences in the growth of shrimp larvae. Larger shrimp larvae may prey on smaller shrimp larvae, affecting their normal growth. This utility model provides a seedling sorting pond for red claw crayfish.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1-5 As shown, an embodiment of this utility model proposes a redclaw crayfish seedling sorting pond, including a pond body 1, with an opening at the top. The pond body 1 contains a water inlet chamber 2, a rearing chamber 3, and a water outlet chamber 4 connected sequentially. Figure 5 As shown, the inlet chamber 2, the aquaculture chamber 3, and the outlet chamber 4 are connected sequentially from left to right. A circulation pump 5 is installed on the tank body 1, and the circulation pump 5 is fixed to the tank body 1. Both the input and output ends of the circulation pump 5 are provided with pipes 6, and their free ends are connected to the inlet chamber 2 and the outlet chamber 4, respectively. An aquaculture frame 7 is installed inside the aquaculture chamber 3. The top of the aquaculture frame 7 is open, and multiple through holes are constructed on the aquaculture frame 7. Multiple partition frames 8 are installed inside the aquaculture frame 7. The multiple partition frames 8 are all vertical and spaced apart, and multiple partition frames 8 are arranged vertically. The divider 8 divides the breeding frame 7 into multiple breeding areas 9. The divider 8 includes a horizontal plate 801, which is horizontal and fixed inside the breeding frame 7. Multiple cylindrical rods 802 are provided on the horizontal plate 801. The cylindrical rods 802 are vertical and fixed on the horizontal plate 801. A channel is formed between two adjacent cylindrical rods 802 for shrimp larvae to pass through. The distance between the channels on two adjacent dividers 8 decreases along the water flow direction. Here, the water flow direction refers to the direction of the inlet chamber 2, the breeding chamber 3, and the outlet chamber 4.

[0025] When in use, water is poured into the pond 1, and the shrimp larvae are placed in the rearing area 9 closest to the inlet chamber 2. After a period of rearing, the shrimp larvae will show differences in growth, resulting in shrimp larvae of different sizes. This will cause the circulation pump 5 to work, and the water in the pond 1 will circulate along the flow direction of the inlet chamber 2, the rearing chamber 3, the outlet chamber 4, one of the pipes 6, the circulation pump 5, the other pipe 6, and the inlet chamber 2. During this process, the larger shrimp larvae will stay in the previous rearing area 9, while the smaller shrimp larvae will pass through the channel and enter the next rearing area 9 under the action of the water flow. This process is repeated to separate the shrimp larvae of different sizes, achieve separate rearing, avoid cannibalism, ensure normal growth, and eliminate the need for human intervention.

[0026] In summary, this utility model allows for the sorting of shrimp larvae of different sizes without human intervention, enabling separate rearing, preventing cannibalism, and ensuring normal growth, thus making it more practical.

[0027] like Figure 3 As shown, the specific structure of the multiple aquaculture zones 9 of this utility model is disclosed, and the volume of the multiple aquaculture zones 9 decreases sequentially along the water flow direction;

[0028] Referring to the above, during the breeding process, larger shrimp larvae require more activity space, while smaller shrimp larvae require less activity space. By designing multiple breeding zones 9 with volumes decreasing sequentially along the water flow direction, the activity needs of shrimp larvae of different sizes can be met.

[0029] like Figures 2-7 As shown, the specific structure and further technical solutions of the water inlet chamber 2, the aquaculture chamber 3, the water outlet chamber 4, and the aquaculture frame 7 of this utility model are disclosed. The water inlet chamber 2, the aquaculture chamber 3, and the water outlet chamber 4 form a stepped structure in sequence. The aquaculture frame 7 is slidably disposed in the aquaculture chamber 3. The aquaculture frame 7 slides in the vertical direction. The aquaculture frame 7 includes a frame body 701. The frame body 701 is vertical and has a rectangular ring structure. A bottom plate 702 is detachably disposed at the bottom of the frame body 701. The bottom plate 702 is horizontal. A horizontal plate 801 is fixed in the frame body 701. The bottom end of the cylindrical rod 802 abuts and overlaps with the bottom plate 702.

[0030] Referring to the above, in the initial state, the bottom plate 702 is installed at the bottom of the frame 701, and the breeding frame 7 is completely located inside the breeding chamber 3. When the shrimp larvae grow to a certain size, the breeding frame 7 is slid upwards to exit the breeding chamber 3, and then the bottom plate 702 is separated from the frame 701. This not only makes it easier to transfer the shrimp larvae to the normal breeding pond, but also makes it easier to clean the bottom plate 702 and the frame 701.

[0031] like Figure 7 As shown, the entire structure of the breeding frame 7 of this utility model is disclosed. Two positioning rods 703 are provided at the bottom of the frame 701. The positioning rods 703 are horizontal and fixed at the bottom of the frame 701. The two positioning rods 703 are distributed at intervals. Two positioning holes 704 are opened on the bottom plate 702. The positioning holes 704 are opened along the length direction of the bottom plate 702. The two positioning rods 703 are respectively inserted into the two positioning holes 704.

[0032] Referring to the above, in the initial state, the base plate 702 is installed at the bottom of the frame 701, and the two positioning rods 703 are respectively and fully inserted into the two positioning holes 704. When it is necessary to separate the base plate 702 from the frame 701, the base plate 702 is moved horizontally away from the frame 701 until the two positioning rods 703 are respectively withdrawn from the two positioning holes 704.

[0033] like Figure 3 As shown, a further technical solution of the present utility model is disclosed. The top of the frame 701 is provided with an escape-proof ring plate 10 that is conical in shape and tapers inward. The escape-proof ring plate 10 is fixed to the top of the frame 701.

[0034] Referring to the above, during the breeding process, the escape-proof ring plate 10 can prevent shrimp larvae from escaping from the top opening of the frame 701, thereby indirectly improving the survival rate of shrimp larvae.

[0035] like Figure 5 As shown, a further technical solution of the present utility model is disclosed. The pool body 1 is constructed with a collection chamber 11 that is connected to the breeding chamber 3. The collection chamber 11 is located at the bottom of the breeding chamber 3. The collection chamber 11 is constructed in an inwardly tapered shape. A discharge pipe 12 is connected to the collection chamber 11. The discharge pipe 12 is vertical. A valve 13 is provided on the discharge pipe 12. The valve 13 is fixed on the discharge pipe 12.

[0036] Referring to the above, in the initial state, valve 13 is closed. When in use, the water in the pool 1 can be discharged through the drain pipe 12 by opening valve 13. The conical design of the collecting chamber 11, which contracts inward, facilitates the smooth discharge of water from the pool 1. Afterward, valve 13 is closed, and water is refilled into the pool 1 to facilitate water replacement. When not in use, the water in the pool 1 can be discharged by opening valve 13 to facilitate cleaning of the pool 1.

[0037] like Figures 5-6 As shown, a further technical solution of this utility model is disclosed: a filter screen plate 14 is slidably arranged in the water outlet cavity 4, and the filter screen plate 14 is vertical and slides in the vertical direction.

[0038] Referring to the above, in the initial state, the filter screen 14 is located in the water outlet chamber 4. During use, the filter screen 14 can filter impurities in the water, preventing impurities from entering the circulation pump 5 with the water and causing the circulation pump 5 to become clogged. The filter screen 14 can be slid upwards to exit the water outlet chamber 4 to facilitate cleaning of the filter screen 14 and prevent the filter screen 14 from becoming clogged.

[0039] like Figures 5-6 As shown, a further technical solution of the present utility model is disclosed. There are two filter screens 14 and they are spaced apart. The filter screens 14 abut against and overlap with the top of the pool body 1. The filter screens 14 are provided with mounting holes 15. The mounting holes 15 are vertical. The pool body 1 is provided with protruding posts 16 in the same number as the mounting holes 15 and they are inserted and matched one by one. The protruding posts 16 are vertical and fixed to the top of the pool body 1.

[0040] Referring to the above, in the initial state, both filter screens 14 are located in the water outlet chamber 4 and are in contact with the top of the tank body 1. The protrusions 16 are correspondingly inserted into the mounting holes 15. The two filter screens 14 are spaced apart. In use, one of the filter screens 14 is slid upwards until it exits the water outlet chamber 4 and moves away from the top of the tank body 1. The protrusions 16 exit the mounting holes 15 to facilitate cleaning of this filter screen 14. At this time, the other filter screen 14 performs the filtering function. After the previous filter screen 14 is cleaned, the filter screen 14 is slid back into the water outlet chamber 4 and in contact with the top of the tank body 1. The protrusions 16 are correspondingly inserted into the mounting holes 15. The above operation is then repeated for the other filter screen 14 so that the circulation pump 5 does not need to stop working when the filter screen 14 is disassembled and cleaned, making it more convenient to use.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
