[0029] Such as Figures 1-9As shown in the figure, it relates to a grading and screening device for mandarin fish fry, including a box body 1. In the center of the interior of the box body 1, a base 2 is fixedly connected. On both sides of the upper end of the base 2, side plates 3 are symmetrically and fixedly connected. At the top position between the side plates 3, a first inclined slide 4 is fixedly connected. Below the lower end of the first inclined slide 4, a first water tank 5 is arranged. Below the first water tank 5, a second inclined slide 6 is arranged. Below the lower end of the second inclined slide 6, a second water tank 7 is arranged. Below the second water tank 7, a third inclined slide 8 is arranged. Below the lower end of the third inclined slide 8, a third water tank 9 is arranged. At the upper ends inside the first water tank 5, the second water tank 7, and the third water tank 9, sieve boxes 10 are arranged. The bottoms of the first water tank 5 and the second water tank 7 are both in a funnel shape and are both provided with openings. At the positions of the openings on the bottom sides of the first water tank 5 and the second water tank 7, baffles 11 are arranged. Initially, the baffles 11 are both closed with the corresponding openings. On the inner side of one side plate 3, at the positions above the first water tank 5, the second water tank 7, and the third water tank 9, water outlet pipes 18 are fixedly connected. On one side of the box body 1, a water pump 19 is fixedly connected.

[0030] As Figures 1-9 shown, both ends of the first water tank 5, the second inclined slide 6, the second water tank 7, and the third inclined slide 8 are fixedly connected to the corresponding side plates 3. Initially, the first water tank 5, the second water tank 7, and the third water tank 9 all contain water and submerge the bottoms of the corresponding sieve boxes 10, playing a buffering role for the mandarin fish fry sliding from above and reducing the harm to the mandarin fish fry.

[0031] As Figures 1-9 shown, the sieve hole diameters of the sieve boxes 10 inside the first water tank 5, the second water tank 7, and the third water tank 9 are different and decrease successively from top to bottom. At both sides of the top ends of the sieve boxes 10, clamping grooves 17 are opened. The edges on both sides of the first water tank 5, the second water tank 7, and the third water tank 9 are clamped with the clamping grooves 17 of the corresponding sieve boxes 10, facilitating the loading and unloading of the sieve boxes 10.

[0032] As Figures 1-9As shown in the figure, sliding grooves 13 are provided at the positions of the side plates 3 on both sides corresponding to the baffle plates 11. Connecting blocks 12 are fixedly connected to both ends of the baffle plates 11. One ends of the connecting blocks 12 are slidably connected in the corresponding sliding grooves 13. A screw rod 14 is rotatably connected in one of the sliding grooves 13. One end of the screw rod 14 is threadedly connected to the corresponding connecting block 12. A limiting rod 16 is fixedly connected in one of the sliding grooves 13. The limiting rod 16 is slidably connected to the corresponding connecting block 12. Rotating handles 15 are rotatably connected to the sides of the side plates 3 at the positions corresponding to the screw rods 14. One end of the screw rod 14 penetrates through the side wall of the corresponding side plate 3 and is fixedly connected to the corresponding rotating handle 15. Rotating the rotating handle 15 corresponding to the baffle plate 11 at the bottom of the first water tank 5 or the second water tank 7 can drive the corresponding screw rod 14 to rotate, and then drive the corresponding connecting block 12 and baffle plate 11 to slide outwards along the sliding groove 13, opening the opening at the bottom of the first water tank 5 or the second water tank 7, facilitating pouring the screened mandarin fish fry together with water downwards to continue the next screening operation.

[0033] As Figures 1-9 As shown in the figure, a communicating pipe 24 is fixedly connected to the input end of the water pump 19. One end of the communicating pipe 24 penetrates and communicates with the inside of the box body 1. The output end of the water pump 19 is fixedly connected to a first water delivery pipe 20. A flow divider 21 is arranged at one end of the first water delivery pipe 20. The three output ports of the flow divider 21 are respectively fixedly connected to second water delivery pipes 22. One ends of the second water delivery pipes 22 respectively penetrate through the corresponding side plates 3 and communicate with the corresponding water outlet pipes 18. Control valves 23 are arranged at one ends of the second water delivery pipes 22. After each screening is completed, by opening the corresponding control valves 23, the water in the box body 1 can be transported to the corresponding first water tank 5, second water tank 7, and third water tank 9 through the first water delivery pipe 20, flow divider 21, second water delivery pipes 22, and water outlet pipes 18, adding water to play a buffering role for the fry during screening, and the water flows back into the box body 1 from above after screening, thus facilitating the recycling of the water in the box body 1 and reducing the waste of water resources.

[0034] Working principle: During use, the mandarin fish fry to be screened, together with water, are poured onto the first inclined slide 4. Under the action of gravity, they slide along the first inclined slide 4 into the sieve box 10 of the first water tank 5. Take out the sieve box 10 in the first water tank 5. The mandarin fish fry larger than the aperture of the sieve box 10 in the first water tank 5 will be screened out, and the mandarin fish fry smaller than the aperture of the sieve box 10 in the first water tank 5 will remain in the first water tank 5. Rotate the turning handle 15 corresponding to the bottom baffle 11 of the first water tank 5, thereby driving the corresponding screw 14 to rotate, and then driving the corresponding connecting block 12 and baffle 11 to slide outwards along the chute 13, opening the opening at the bottom of the first water tank 5. Thus, the water in the first water tank 5 together with the remaining mandarin fish fry will pour down onto the second inclined slide 6. Similarly, they slide along the second inclined slide 6 into the sieve box 10 of the second water tank 7. Take out the sieve box 10 in the second water tank 7. Thus, the mandarin fish fry larger than the aperture of the sieve box 10 in the second water tank 7 will be screened out, and the mandarin fish fry smaller than the aperture of the sieve box 10 in the second water tank 7 will remain in the second water tank 7. Similarly, then rotate the corresponding turning handle 15 to move the baffle 11 at the bottom opening of the second water tank 7 away. Thus, the water in the second water tank 7 together with the remaining mandarin fish fry will pour down onto the third inclined slide 8. They slide along the third inclined slide 8 into the sieve box 10 of the third water tank 9. Take out the sieve box 10 in the third water tank 9. The mandarin fish fry larger than the aperture of the sieve box 10 in the third water tank 9 will be screened out, and the mandarin fish fry smaller than the aperture of the sieve box 10 in the third water tank 9 will remain in the third water tank 9. In this way, the mandarin fish fry can be classified and screened according to size, and the first water tank 5, the second water tank 7, and the third water tank 9 can be screened independently and synchronously without affecting each other. After each screening, open the corresponding control valve 23, and the water in the box body 1 can be transported to the corresponding first water tank 5, second water tank 7, and third water tank 9 through the first water pipe 20, the diverter 21, the second water pipe 22, and the water outlet pipe 18, adding water to play a buffering role for the fry during the next screening. And after screening, the water flows back into the box body 1 from above, thereby facilitating the recycling of the water in the box body 1 and reducing the waste of water resources.
