Description

Technical Field

[0001] The present invention relates to the technical field of logistics boxes, and in particular to a logistics box for transporting silver pomfret fry. Background Art

[0002] Silver Pomfret is a warm-water pelagic fish of the family Pomfret, order Perciformes. It is 85 to 260 mm long, short and tall, extremely flattened, and slightly diamond-shaped; it has a small and slightly oblique mouth, no pelvic fins, and a deeply forked tail fin; the lower lobe is longer than the upper lobe, resembling a swallowtail; the body is silvery white, with a slightly yellow-gray upper part; the round scales are very small, and most of the scales have tiny black dots, which is why it is named because of its silvery white color. When the fry are cultivated to a certain size, they need to be released into open waters, so special logistics boxes are needed.

[0003] An existing long-distance fry transport box (Announcement No.: CN109937956B) has at least the following disadvantages:

[0004] When the above patent is in use, the scraper plate can be used to scrape the food residues and floating dirt such as fish carcasses on the top of the water tank to the side box on the opposite side, and the waste on the top of the water tank is continued to be cleaned. The fourth rotary motor drives the rotary plate to rotate, and the dirt pressed down by the filter plate is directly changed to the bottom, so that the dirt is rotated from the top surface of the rotary plate to the bottom surface of the rotary plate, and the dirt that sinks to the bottom falls down by its own weight. Since the fry will produce a large amount of pollutants such as fish feces during long-term transportation, it is necessary to regularly remove the pollutants such as fish feces in the water, and the fry are always active inside the logistics box, so the pollutants such as fish feces will be stirred and suspended in the water. The above patent can only remove the fish feces and pollutants on the water surface and the bottom of the water, but cannot remove the suspended fish feces and pollutants. The suspended fish feces and pollutants will greatly reduce the dissolved oxygen content in the water, resulting in the death of the silver pomfret fry. Summary of the invention

[0034] Reference Figure 1-Figure 11A silver pomfret fry transport logistics box includes a cylindrical box 1, a hollow shaft 9 is rotatably installed between the inner walls at opposite ends of the cylindrical box 1, and sealing end covers are fixedly installed on the inner walls of the hollow shaft 9 near the two ends, and a fixed sleeve 13 is fixedly installed on the outer surface of the hollow shaft 9, and the bottom end of the fixed sleeve 13 is against the inner wall of the cylindrical box 1, and the outer surfaces of the opposite sides of the fixed sleeve 13 are equidistantly penetrated with a plurality of water inlet holes 21, and the outer surface of the fixed sleeve 13 is slidably provided with a sliding sleeve 14, and the outer surfaces of the sliding sleeve 14 on the opposite sides are A plurality of identical water inlet holes 21 are evenly spaced and penetrated, and the water inlet holes 21 are arranged in a square shape. The top of the fixed sleeve 13 penetrates the inner wall of the hollow shaft 9 and is connected with the interior thereof. Two dovetail slide grooves 2601 are symmetrically arranged on the inner walls at opposite ends of the fixed sleeve 13, and a filter plate 23 is slidably installed between the two dovetail slide grooves 2601. Two dovetail slide rails 26 are symmetrically fixedly installed on the outer surfaces at opposite ends of the filter plate 23, and the dovetail slide rails 26 are slidably installed on the inner wall of the dovetail slide groove 2601. The two dovetail slides The outer surface of the rail 26 near the top is threadedly connected with a fixing screw 27, one end of the fixing screw 27 penetrates the outer surface of the dovetail rail 26 and abuts against the inner wall of the dovetail slot 2601. The inner walls of the opposite ends of the fixing sleeve 13 are symmetrically provided with two groups of L-shaped slots 2201, and the inner walls of the two L-shaped slots 2201 in one group are both slidably installed with L-shaped sliders 22. A scraper 24 is fixedly installed between the two L-shaped sliders 22. The two scrapers 24 are respectively arranged on both sides of the filter plate 23. The scraper 24 is fixedly installed between the two L-shaped sliders 22. The outer surface of the hollow shaft 9 is flush with the outer surfaces of the fixed sleeve 13 and the filter plate 23. Two baffles 25 are fixedly installed on the top of the filter plate 23. The two baffles 25 are arranged above the scraper 24. A driven gear 10 is fixedly installed on the circumferential outer surface of one end of the hollow shaft 9. A driving motor 6 is fixedly installed on the outer surface of the housing 5 close to the driven gear 10. The output end of the driving motor 6 passes through the outer surface of the housing 5 and is fixedly installed with a driving gear 11. The driving gear 11 is meshed with the driven gear 10.

[0035] By controlling the driving motor 6 to rotate, the driving gear 11 and the driven gear 10 drive the hollow shaft 9 to rotate, and the hollow shaft 9 drives the fixed sleeve 13 to rotate 180° to the inside of the box cover 2. When the fixed sleeve 13 moves in the water, due to the relative displacement with the water, the water enters the surface of the filter plate 23 from the water inlet hole 21. Since the filter plate 23 is constantly moving, the fish feces and pollutants in the water will be filtered out. When the fixed sleeve 13 rotates to 160°, the sliding sleeve 14 will slide downward by its own gravity. At this time, the inner wall of the sliding sleeve 14 will leave the positioning column, and the positioning column will slide out of the positioning hole 19 under the action of the first spring 1403. When the sliding sleeve 14 completely slides to the bottom, the sliding of the sliding sleeve 14 makes the water inlet hole 21 on the sliding sleeve 14 and the fixed sleeve 13 The water inlet holes 21 on the filter plate 23 are staggered with each other to separate the water inside the fixed sleeve 13 from the water outside; the fixed sleeve 13 rotates, so that the two scrapers 24 will slide downward again under their own gravity, and the fish feces and pollutants filtered from the outer surface of the filter plate 23 will be scraped into the interior of the hollow shaft 9 by the downward movement of the scraper 24. Since a part of water will remain inside the fixed sleeve 13 and the hollow shaft 9, after the fixed sleeve 13 rotates to a position of 180°, at this time, the guide hole 701 and the sewage outlet 901 are connected, and the fish feces and pollutants scraped by the scraper 24 will be discharged from the guide hole 701 and the sewage outlet 901 to the collection box below along with the residual water. The device can filter and discharge the fish feces and pollutants suspended in the water, ensure the sufficient amount of dissolved oxygen in the water, and improve the survival rate of silver pomfret fry.

[0036] In this embodiment, a limit assembly for limiting the sliding of the scraper 24 is arranged between the scraper 24 and the sliding sleeve 14. The limit assembly includes two groups of circular grooves symmetrically opened on the outer surfaces of the opposite ends of the fixed sleeve 13 in groups of two. The inner walls of a group of two circular grooves are slidably installed with sliding caps 1402. The outer surfaces of the sliding caps 1402 are penetrated with positioning columns. The positioning columns and the sliding caps 1402 are fixedly installed. The end surfaces of the opposite ends of the scraper 24 are provided with positioning holes 19 matching the positioning columns. One end of the positioning column penetrates the inner wall of the fixed sleeve 13 and is inserted into the interior of the positioning hole 19. The inner wall of the sliding sleeve 14 near a group of two sliding caps 1402 is provided with two oblique openings 1401. The other end of the positioning column is against the inner wall of the oblique opening 1401. The outer surface of the positioning column is sleeved with a first spring 1403. One end of the first spring 1403 is fixedly connected to the outer surface of the sliding cap 1402, and the other end of the first spring 1403 is fixedly connected to the inner wall of the circular groove.

[0037] When the fixed sleeve 13 starts to rotate downward, the scraper 24 will first slide to the bottom end of the fixed sleeve 13 due to its heavy weight and small friction contact surface. The scraper 24 will be limited at the bottom end of the fixed sleeve 13 by the blocking bar 25. When the fixed sleeve 13 continues to rotate downward, the sliding sleeve 14 will slide downward. At this time, the sliding sleeve 14 makes the inner wall of the sliding sleeve 14 abut against one end of the positioning column through the inclined opening 1401, so that the positioning column is inserted into the interior of the positioning hole 19 to re-limit the position of the scraper 24.

[0038] In this embodiment, two buffer plates 12 are symmetrically arranged on the outer surfaces of the opposite sides of the sliding sleeve 14, and two groups of support blocks 15 are fixedly installed on the outer surfaces of the opposite sides of the sliding sleeve 14 in pairs. Two slide rods 17 are symmetrically fixedly installed on the outer surfaces of the opposite ends of the buffer plate 12, and the other end of the slide rod 17 passes through the outer surface of the support block 15 and is fixedly installed with a baffle 16. The slide rod 17 is slidably installed with the support block 15, and the outer surface of the slide rod 17 is sleeved with a second spring 18, which is arranged between the support block 15 and the buffer plate 1 2, multiple grille holes 1201 are equidistantly penetrated on the outer surfaces of the opposite sides of the buffer plate 12, multiple partitions 20 are equidistantly fixedly installed on the outer surfaces of the opposite sides of the buffer plate 12, the grille holes 1201 are arranged between two adjacent partitions 20, the distance between two adjacent water inlet holes 21 is greater than the side length of the water inlet holes 21, the width of the sliding sleeve 14 is shorter than the width of the fixed sleeve 13, and the grille holes 1201 can be changed into multiple honeycomb holes as needed in actual use, which is more conducive to making the air denser.

[0039] The partition 20 and the second spring 18 on the buffer plate 12 can reduce the surging intensity of the water, thereby preventing the silver pomfret fry from being hit by the inner wall of the cylindrical box 1 and causing the death of the fry; at the same time, the buffer plate 12 is driven to reciprocate by the shaking of the water and the partition 20. When the buffer plate 12 reciprocates, the size of the connecting pore between the grille hole 1201 and the water inlet hole 21 changes back and forth. When the connecting pore between the grille hole 1201 and the water inlet hole 21 becomes smaller, since the air supply pressure of the external air pump is constant, the air discharged from the water inlet hole 21 and the grille hole 1201 is more dense, and it is easier for the oxygen in the air to blend into the water, thereby increasing the survival rate of the silver pomfret fry.

[0040] In this embodiment, both ends of the hollow shaft 9 penetrate the two end surfaces of the cylindrical box 1, and the end surfaces of the opposite ends of the hollow shaft 9 are provided with air inlets 902, a flow channel is provided inside the hollow shaft 9, and a plurality of air outlets 903 are provided at equal intervals on the inner wall of the hollow shaft 9, and the air inlet 902 is connected with the plurality of air outlets 903 through the flow channel. The end surfaces of the opposite ends of the cylindrical box 1 are fixedly installed with a shell 5, and the outer surface of the shell 5 is fixedly installed with a guide tube 7, and the end of the guide tube 7 close to the cylindrical box 1 penetrates the shell 5. The outer surface is against the end face of the hollow shaft 9, and a guide hole 701 is penetrated through the bottom wall of the guide tube 7 near the end of the cylindrical box 1. The sealing end covers at both ends of the hollow shaft 9 are penetrated with the same sewage outlet 901. An air inlet hole is opened inside the guide tube 7, and an air inlet pipe joint 8 is fixedly installed at the air inlet end of the air inlet hole. The air outlet end of the air inlet hole is connected with the air inlet port 902. The air inlet pipe joint 8 on the guide tube 7 is arranged directly above the guide hole 701, and the sewage outlet 901 is connected with the guide hole 701.

[0041] When the silver pomfret fry are being transported, the external air pump is connected to the air inlet pipe joint 8 through the air pipe, and the air pump conveys the external air to the flow channel inside the hollow shaft 9 through the air inlet hole inside the guide tube 7 and the air inlet 902 on the end face of the hollow shaft 9. The air is ejected from the air outlet 903 through the flow channel, enters the interior of the fixed sleeve 13, and then is discharged from the water inlet hole 21 on the surface of the fixed sleeve 13 into the breeding water, filling the interior of the water with oxygen for the life of the silver pomfret fry.

[0042] In this embodiment, a box cover 2 is hinged on the outer surface of the cylindrical box 1 near the top, and a plurality of through holes 3 are penetrated through the upper surface of the box cover 2. A lock 4 is provided on the outer surface of the cylindrical box 1. After the water is filled, a certain number of silver pomfret fry are placed into the interior of the cylindrical box 1, and then the box cover 2 is closed and fixed to the cylindrical box 1 by the lock 4.

[0043] It should be noted that when the present invention is used, the user places the cylindrical box 1 on a transport vehicle, and then injects a certain amount of water into the cylindrical box 1 for the silver pomfret fry to live. It should be noted that the amount of water injected should exceed a certain distance of the height of the hollow shaft 9. After the water injection is completed, a certain number of silver pomfret fry are placed into the cylindrical box 1, and then the box cover 2 is closed and fixed to the cylindrical box 1 by the lock 4;

[0044] In the initial position, the fixed sleeve 13 is vertically inside the cylindrical box 1. When the silver pomfret fry is being transported, the external air pump is connected to the air inlet pipe joint 8 through the air pipe. The air pump conveys the external air to the flow channel inside the hollow shaft 9 through the air inlet hole inside the guide tube 7 and the air inlet 902 on the end face of the hollow shaft 9. The air is ejected from the air outlet 903 through the flow channel and enters the interior of the fixed sleeve 13. Then, the air is discharged from the water inlet hole 21 on the surface of the fixed sleeve 13 into the aquaculture water, and the water is filled with oxygen for the silver pomfret fry to live.

[0045] When the cylindrical box 1 moves on the vehicle, the shaking of the vehicle causes the water inside the cylindrical box 1 to shake constantly. The partition 20 and the second spring 18 on the buffer plate 12 can reduce the surging strength of the water, thereby preventing the silver pomfret fry from being hit by the inner wall of the cylindrical box 1 and causing the death of the fry. At the same time, the shaking of the water and the partition 20 drive the buffer plate 12 to reciprocate. When the buffer plate 12 reciprocates, the size of the connecting pore between the grille hole 1201 and the water inlet hole 21 changes back and forth. When the connecting pore between the grille hole 1201 and the water inlet hole 21 becomes smaller, since the air supply pressure of the external air pump is constant, the air discharged from the water inlet hole 21 and the grille hole 1201 becomes more dense, and it is easier for the oxygen in the air to blend into the water, thereby increasing the survival rate of the silver pomfret fry.

[0046] When it is necessary to clean the fish excrement and pollutants suspended in the water of the cylindrical box 1, the user stops the transport vehicle and controls the driving motor 6 to rotate, so that the driving gear 11 and the driven gear 10 drive the hollow shaft 9 to rotate, and the hollow shaft 9 drives the fixed sleeve 13 to rotate 180° to the inside of the box cover 2. When the fixed sleeve 13 moves in the water, due to the relative displacement with the water, the water enters the surface of the filter plate 23 from the water inlet hole 21. Since the filter plate 23 is moving all the time, the fish excrement and pollutants in the water can be filtered out. When the fixed sleeve 13 rotates to 160°, the sliding sleeve 14 will slide downward by its own gravity. At this time, the inner wall of the sliding sleeve 14 will leave the positioning column, and the positioning column will slide out of the positioning hole 19 under the action of the first spring 1403. When the sliding sleeve 14 completely slides to the bottom, the sliding of the sliding sleeve 14 makes the water inlet hole 21 on the sliding sleeve 14 and the water inlet hole 21 on the fixed sleeve 13 staggered with each other, separating the inside of the fixed sleeve 13 from the water outside.

[0047] Because the positioning column leaves the positioning hole 19, after the fixed sleeve 13 rotates to the position of 180°, the two scrapers 24 will slide downward again under their own gravity, and the fish feces and pollutants filtered on the outer surface of the filter plate 23 will be scraped into the interior of the hollow shaft 9 through the downward movement of the scraper 24. Since some water will remain inside the fixed sleeve 13 and the hollow shaft 9, after the fixed sleeve 13 rotates to the position of 180°, the guide hole 701 and the sewage outlet 901 are connected. The fish feces and pollutants scraped by the scraper 24 will be discharged from the guide hole 701 and the sewage outlet 901 with the residual water to the collection box below, waiting to be processed after the transportation is completed. Since the amount of water discharged each time is small, it will not affect the cylindrical box 1. When the fixed sleeve 13 starts to rotate downward, the scraper 24 is heavier and has a smaller friction contact surface, so it will first slide to the bottom of the fixed sleeve 13. The scraper 24 is limited at the bottom of the fixed sleeve 13 by the blocking bar 25. When the fixed sleeve 13 continues to rotate downward, the sliding sleeve 14 will slide downward. At this time, the water inlet hole 21 on the sliding sleeve 14 and the water inlet hole 21 on the fixed sleeve 13 overlap with each other. The operator can filter out the fish feces and pollutants suspended in the water by controlling the driving motor 6 to rotate a few times. The device can filter and discharge the fish feces and pollutants suspended in the water, ensuring sufficient dissolved oxygen in the water and improving the survival rate of the silver pomfret fry.

[0048] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
