Description

Technical Field

[0001] The utility model relates to the technical field of shrimp fry breeding devices, in particular to a shrimp fry grading breeding device. Background Art

[0002] In the process of fresh shrimp farming, the shrimp fry need to be cultivated first, and then the qualified shrimp fry need to be transferred to the breeding pond for breeding. In the process of cultivating shrimp fry, a shrimp fry breeding device is needed for auxiliary breeding.

[0003] In actual work, the structure and function of the shrimp fry breeding device in the prior art are relatively complete, which can basically meet the breeding work of shrimp fry, but there are still the following two problems:

[0004] 1. The existing shrimp seedling breeding devices generally breed shrimp seedlings together, and manual operation is often required to sort the larger shrimp seedlings from the smaller ones. Manual sorting increases labor time and labor costs, and greatly reduces sorting efficiency;

[0005] 2. Mixed breeding of large and small shrimp seedlings will result in the inability to achieve uniform feeding and oxygen content in the water body. Since shrimp seedlings of different sizes have different requirements for feed and oxygen, excessive feed or high oxygen content that cannot be consumed in time will cause eutrophication of the water body, thereby increasing the malignant reproduction of other plankton or plants and affecting the health of the water body.

[0006] Therefore, the utility model provides a shrimp fry grading culture device. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings of the prior art and provide a shrimp fry grading culture device.

[0009] As a preferred embodiment, a first filter hole is provided at the bottom of the first breeding frame, a second filter hole is provided on the inner wall of the second breeding frame, the diameter of the first filter hole is smaller than the diameter of the second filter hole, the inner wall of the first breeding frame is located above the second rectangular through hole and is fixedly connected to a U-shaped frame, the inner wall of the U-shaped frame is rotatably connected to a rotating rod, the outer surface of the rotating rod is fixedly connected to a rotating round block, the outer surface of the rotating rod is sleeved with a torsion spring, the two ends of the torsion spring are respectively fixedly connected to the rotating round block and the U-shaped frame, the outer surface of the rotating round block is fixedly connected to a shielding plate, the width of the shielding plate is greater than the width of the second rectangular through hole, a plugging plate is inserted on the side of the inner wall of the second breeding frame close to the third rectangular through hole, the top of the plugging plate is fixedly connected to a rectangular plate, the inner wall of the rectangular plate is inserted with a locking rod, and the top inner wall of the second breeding frame is provided with a locking hole, and the locking rod can be locked into the inner wall of the locking hole.

[0010] The technical effect of adopting the above-mentioned further scheme is: the rotating rod and the rotating round block can drive the baffle plate to move, so that the shrimp seedlings that meet the size in the second breeding frame can enter the first breeding frame from the first rectangular through hole, the second rectangular through hole and the third rectangular through hole, and then can be automatically graded. Under the action of the plug plate, when the first breeding frame is lifted upward, the smaller shrimp seedlings fall into the breeding pond from the first filter hole and will not enter the second breeding frame from the first rectangular through hole.

[0011] As a preferred embodiment, the auxiliary seedling inducing structure includes a rectangular block, one side of the outer surface of the rectangular block is fixedly connected to one side of the second breeding frame, a sliding rod is inserted into the inner wall of the rectangular block, the top of the outer surface of the sliding rod is fixedly connected to an auxiliary plate, the top of the outer surface of the auxiliary plate is fixedly connected to a power source body, and a high-intensity photoelectric lamp is fixedly installed on the bottom of the auxiliary plate, and the high-intensity photoelectric lamp is electrically connected to the power source body.

[0012] The technical effect of adopting the above further scheme is: under the effect of strong photoelectric lamps, combined with the light-avoidance of shrimp fry, the smaller shrimp fry in the second breeding frame can be guided into the first breeding frame, thereby realizing graded breeding of the second breeding frame and the first breeding frame.

[0013] As a preferred embodiment, a first locking through hole is opened on the inner wall of one side of the rectangular block, a second locking through hole is opened on the inner wall of the sliding rod, and the same locking round rod is inserted into the inner walls of the first locking through hole and the second locking through hole.

[0016] By setting the first breeding frame and the second breeding frame, the baffle plate and the first rectangular through hole, the second rectangular through hole and the third rectangular through hole can be coordinated so that the shrimp seedlings can selectively enter the first breeding frame, and then the larger shrimp seedlings can be placed in the second breeding frame. At the same time, the first filter hole at the bottom of the first breeding frame can filter out the shrimp seedlings that meet the requirements and move them to the second breeding frame, thereby realizing the graded breeding of the shrimp seedlings. At the same time, different feed feeding and oxygen content control can be performed according to the different shrimp seedling sizes in the first breeding frame and the second breeding frame, so that reasonable breeding can be carried out.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Further, such as Figure 2-Figure 4 As shown: a first filter hole is provided at the bottom of the first breeding frame 41, a second filter hole is provided on the inner wall of the second breeding frame 42, the diameter of the first filter hole is smaller than the diameter of the second filter hole, the inner wall of the first breeding frame 41 is located above the second rectangular through hole 43 and is fixedly connected with a U-shaped frame 45, the inner wall of the U-shaped frame 45 is rotatably connected with a rotating rod 46, the outer surface of the rotating rod 46 is fixedly connected with a rotating round block 47, the outer surface of the rotating rod 46 is sleeved with a torsion spring 48, the two ends of the torsion spring 48 are respectively fixedly connected to the rotating round block 47 and the U-shaped frame 45, the outer surface of the rotating round block 47 is fixedly connected with a shielding plate 49, the width of the shielding plate 49 is greater than the width of the second rectangular through hole 43, and a plug plate 4 is inserted on the inner wall of the second breeding frame 42 near the third rectangular through hole 44 10. A rectangular plate 411 is fixedly connected to the top of the plug plate 410, and a locking rod 412 is inserted into the inner wall of the rectangular plate 411. A locking hole 413 is opened on the top inner wall of the second breeding frame 42, and the locking rod 412 can be locked into the inner wall of the locking hole 413. The rotating rod 46 and the rotating round block 47 can drive the shielding plate 49 to move, so that the shrimp seedlings that meet the size in the second breeding frame 42 can enter the first breeding frame 41 from the first rectangular through hole 3, the second rectangular through hole 43 and the third rectangular through hole 44, and then automatic grading can be performed. Under the action of the plug plate 410, when the first breeding frame 41 is lifted upward, the smaller shrimp seedlings fall into the breeding pond 1 from the first filter hole, and will not enter the second breeding frame 42 from the first rectangular through hole 3.

[0027] The above solution also has the problem that the shrimp fry will not actively enter the first breeding frame 41 from the second breeding frame 42, which leads to poor diversion effect. Figure 5 As shown: In the present scheme, the auxiliary seedling inducing structure 5 includes a rectangular block 51, one side of the outer surface of the rectangular block 51 is fixedly connected to one side of the second breeding frame 42, a sliding rod 52 is inserted into the inner wall of the rectangular block 51, the top of the outer surface of the sliding rod 52 is fixedly connected to an auxiliary plate 56, the top of the outer surface of the auxiliary plate 56 is fixedly connected to a power source body 57, and a strong photoelectric lamp 58 is fixedly installed at the bottom of the auxiliary plate 56, and the strong photoelectric lamp 58 is electrically connected to the power source body 57. Under the action of the strong photoelectric lamp 58, combined with the light-shielding nature of the shrimp seedlings, the smaller shrimp seedlings in the second breeding frame 42 can be guided into the first breeding frame 41, thereby realizing the graded breeding of the second breeding frame 42 and the first breeding frame 41.

[0028] In the above solution, there is still a problem that the strong light 58 inside the second breeding frame 42 will affect the taking of the second breeding frame 42, such as Figure 5 As shown, a first locking through hole 53 is provided on the inner wall of one side of the rectangular block 51, a second locking through hole 54 is provided on the inner wall of the sliding rod 52, and the same locking round rod 55 is inserted into the inner walls of the first locking through hole 53 and the second locking through hole 54. The sliding rod 52 cooperates with the first locking through hole 53 and the second locking through hole 54 to remove the high-intensity photoelectric lamp 58 from the second breeding frame 42 and fix it on one side of the breeding pond 1 so that it will not affect the placement and removal of the second breeding frame 42.

[0029] Working principle:

[0030] like Figure 1-5 As shown:

[0031] When in use: the shrimp fry is placed in the first breeding frame 41 or the second breeding frame 42. When placed in the second breeding frame 42, the smaller shrimp fry will enter the second rectangular through hole 43 from the third rectangular through hole 44 and the first rectangular through hole 3, and then drive the shielding plate 49 to rotate, thereby causing the rotating round block 47 and the rotating rod 46 to rotate, and then can enter the first breeding frame 41;

[0032] When the shrimp fry are larger, the first culture frame 41 is lifted, so that the smaller shrimp fry fall from the first filter hole, and the larger shrimp fry remain in the first culture frame 41 and then fall into the second culture frame 42;

[0033] When the shrimp fry in the second culture frame 42 is large, the second culture frame 42 is lifted, so that the smaller shrimp fry fall from the second filter hole, and the shrimp fry that meet the conditions are put into the culture pond for further culture;

[0034] When it is necessary to induce the shrimp fry, the sliding rod 52 is slid upward so that the high-intensity light 58 is located at the top of the second breeding frame 42. The sliding rod 52 is rotated so that the sliding rod 52 can drive the auxiliary plate 56 to rotate, thereby making the high-intensity light 58 located above the second breeding frame 42. The sliding rod 52 is pulled downward so that the high-intensity light 58 falls into the second breeding frame 42. The locking round rod 55 is pressed so that it is locked into the first locking through hole 53 and the second locking through hole 54 for fixation.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
