Description

Technical Field

[0001] The utility model specifically relates to a shrimp seedling safety screening device, belonging to the technical field of shrimp farming. Background Art

[0002] In the aquaculture industry, the screening of shrimp seedlings is a crucial link. Traditional shrimp seedling screening devices often have many problems, such as low screening efficiency, complex operation, and easy damage to shrimp seedlings. These problems not only affect the growth rate and survival rate of shrimp seedlings, but also increase the breeding cost and limit the development of the aquaculture industry. First of all, traditional screening devices mostly use mechanical vibration or water flow impact for screening. This rigid screening method is extremely likely to cause shrimp seedlings to be squeezed and collided during the screening process, resulting in the death or injury of shrimp seedlings. Especially in a high-density aquaculture environment, the phenomenon of mutual sandwiching between shrimp seedlings is more serious, further exacerbating the injury risk during the screening process. Secondly, the screening efficiency of traditional screening devices is low. Due to the different sizes and shapes of shrimp seedlings, traditional screening methods often have difficulty accurately separating shrimp seedlings of different specifications, resulting in unsatisfactory screening results and requiring multiple screenings to achieve the desired effect, increasing the screening time and labor cost. In addition, the structure of traditional screening devices is complex, and installation and maintenance are difficult. This not only increases the difficulty of use for farmers, but also reduces the reliability and service life of the equipment. Currently, a shrimp seedling screening device for green shrimp farming disclosed in Chinese Patent with the patent publication number CN217509679U can achieve the filtration of shrimp seedlings. However, the motor and telescopic rod in the device are located at the bottom, so it is easy to cause the device to enter water, and there is no oxygen supply facility inside. During screening, high-density shrimp are prone to hypoxia. Secondly, the diameter of the mesh holes of its screen cannot be adjusted.

[0003] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a shrimp seedling safety screening device for the deficiencies of the prior art, which can minimize the damage to shrimp seedlings, and the diameter of the mesh holes of the screen can be adjusted to facilitate the screening of shrimp seedlings of different body sizes.

[0005] The present utility model achieves the above object through the following technical solutions. A shrimp seedling safety screening device includes a collecting pool, inside which a screening frame is arranged. Above the screening frame, there is a cross-shaped frame handle. At the intersection of the top of the cross-shaped frame handle, a turntable is connected through a short rod. Above the turntable, there is a motor base. On the right side of the collecting pool, there is a fixed block, on which a vertical rod is arranged. A horizontal rod passes through the vertical rod. One end of the horizontal rod is fixed with the motor base. On the motor base, there is an inverted driving motor. At the top of the vertical rod, there is a top plate. On the upper surface of the top plate, there is an oxygen pipe. On the lower surface of the top plate, there is an inverted telescopic rod, and the top end of the telescopic rod is fixed on the horizontal rod.

[0006] Further, in order to clean out the screened small-sized shrimp seedlings from the collecting pool, a door is provided on the front of the collecting pool. A baffle is arranged on the door, and blocking screws are arranged at the four corners of the baffle. The baffle is fixed on the collecting pool through the four blocking screws.

[0007] Further, in order to facilitate the delivery of oxygen, the inside of the vertical rod is hollow, and the oxygen pipe is communicated with the inside of the vertical rod.

[0008] Further, in order to supply oxygen to the inside of the collecting pool, an oxygen injection main pipe is arranged at the right end of the bottom surface inside the collecting pool. Five oxygen injection thin pipes are evenly arranged on the oxygen injection main pipe at equal intervals. A number of exhaust holes are evenly opened on the five oxygen injection thin pipes. The five oxygen injection thin pipes are laid flat on the bottom surface inside the collecting pool. The oxygen injection main pipe is connected to the inside of the vertical rod through a short pipe and communicated with the oxygen pipe.

[0009] Further, in order to enable the driving motor to drive the screening frame to perform circular motion inside the collecting pool, the output end of the driving motor is fixed at one end of the upper surface of the turntable. The intersection of the top of the cross-shaped frame handle is connected to one end of the bottom surface of the turntable through a short rod, and the two form an eccentric structure.

[0010] Further, in order to clean out the screened large-sized shrimp from the screening frame, a sliding door is arranged on the front of the screening frame. A pushing block is arranged on the sliding door. Slide rails are arranged at both the upper and lower ends of the sliding door, and the slide rails are fixed on the screening frame. The sliding door is embedded between the two slide rails.

[0011] Further, in order to perform filtering and screening and adjust the sieve hole size when needed, a bottom sieve plate is arranged on the inner bottom surface of the screening frame. An upper sieve plate is arranged above the bottom sieve plate. Diamond-shaped sieve holes are evenly opened on both the bottom sieve plate and the upper sieve plate.

[0012] Further, in order to facilitate the movement and fixation of the upper sieve plate, the upper sieve plate is clamped above the bottom sieve plate by two upper and lower clamping plates, and two tightening nuts are arranged on each of the two clamping plates.

[0013] Beneficial effects: In this utility model, the driving motor and the telescopic rod are placed above the entire device. Therefore, the bottom water collecting pool and the screening frame can be placed in water for screening, or it can prevent electrical equipment from getting water. Moreover, oxygen injection fine tubes are added at the bottom of the water collecting pool to supply oxygen to the high-density shrimp larvae being screened, preventing them from dying due to lack of oxygen. The dislocation of the upper sieve plate and the bottom sieve plate inside the screening frame can change the size of the sieve holes, thereby adjusting the size of the screened shrimp larvae. The design of this utility model is simple in structure, stable in structure, and convenient for installation. Description of the Drawings

A horizontal rod 9 is penetrated through the vertical rod 10. The motor base 7 is fixed at one end of the horizontal rod 9. On the motor base 7, an inverted drive motor 8 is provided. At the top of the vertical rod 10, a top plate 13 is provided. On the upper surface of the top plate 13, an oxygen supply pipe 14 is provided, which can be connected to an oxygen supply device. On the lower surface of the top plate 13, an inverted telescopic rod 12 is provided. The top end of the telescopic rod 12 is fixed on the horizontal rod 9. In this way, the telescopic rod 12 can drive the entire screening frame 4 to move up and down, facilitating the screening of shrimp fry.

[0024] On the front of the collection pool 1, a door is provided. On the door, a baffle 2 is provided. At the four corners of the baffle 2, blocking screws 3 are provided. The baffle 2 is fixed on the collection pool 1 through the four blocking screws 3. In this way, after screening, small-sized shrimp fry can be flushed out with running water, reducing damage to the shrimp fry.

[0025] The inside of the vertical rod 10 is hollow, and the oxygen supply pipe 14 communicates with the inside of the vertical rod 10, facilitating the delivery of oxygen.

[0026] At the right end of the bottom surface inside the collection pool 1, an oxygen injection main pipe 101 is provided. Five oxygen injection thin pipes 102 are evenly and equidistantly arranged on the oxygen injection main pipe 101. A number of exhaust holes 103 are evenly opened on the five oxygen injection thin pipes 102. The five oxygen injection thin pipes 102 are laid flat on the bottom surface inside the collection pool 1.

[0027] The output end of the driving motor 8 is fixed at one end of the upper surface of the turntable 6. The intersection of the top of the cross-shaped frame handle 5 is connected to one end of the bottom surface of the turntable 6 through a short rod, and the two form an eccentric structure. In this way, the driving motor 8 can drive the entire screening frame 4 and the cross-shaped frame handle 5 above it to perform circular motion inside the collecting pool 1, and then cooperate with the telescopic rod 12 to drive the screening frame 4 to move up and down, so that the smaller shrimp fry can pass through the sieve holes and the larger shrimp can be screened out.

[0028] A sliding door 401 is arranged on the front surface of the screening frame 4. A pushing block 402 is arranged on the sliding door 401. Slide rails 403 are arranged at both the upper and lower ends of the sliding door 401. The slide rails 403 are fixed on the screening frame 4. The sliding door 401 is embedded between the two slide rails 403, so that the larger shrimp can be cleaned out of the screening frame 4 after screening.

[0029] A bottom sieve plate 404 is arranged on the inner bottom surface of the screening frame 4. An upper sieve plate 405 is arranged above the bottom sieve plate 404. Rhombic sieve holes 406 are evenly arranged on both the bottom sieve plate 404 and the upper sieve plate 405, so that the screening function can be achieved.

[0030] The upper sieve plate 405 is clamped above the bottom sieve plate 404 by two upper and lower clamping plates. Two tightening nuts 408 are arranged on both clamping plates. When the size of the sieve holes needs to be adjusted, the tightening nuts 408 can be loosened, and the upper sieve plate 405 is moved to change the size of the sieve holes formed between the upper sieve plate 405 and the bottom sieve plate 404. After selecting the size of the sieve holes, the tightening nuts 408 are tightened again to fix the upper sieve plate 405 to prevent it from moving in the water and affecting the screening efficiency.
