Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a seedling placing device for aquaculture. Background Art

[0002] In aquaculture, young individuals of aquatic species such as fish, shellfish and crustaceans need to be regularly placed into the breeding ponds, so as to achieve a scientific stocking density by replenishing the number of aquatic organisms in the breeding ponds, thereby ensuring the normal productivity of the breeding ponds and improving the overall breeding efficiency.

[0003] However, since the temperature, salinity, pH value and oxygen content of the water in the breeding pond may be different from the water where the fry originally lived, the fry may experience a stress reaction when they are released. In addition, a large number of fry often need to be released in batches, but due to the uncertainty of the fry's swimming, there is a possibility that the fry are too crowded or too scarce when they are released in batches.

At the same time, after the fry have adapted for a certain period of time, the water level difference between the box and the breeding pond and the movement of the movable frame can be used to smoothly deliver the fry into the breeding pond, reducing the possibility of the fry being injured during delivery.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 7 The embodiment of the present invention provides a seedling delivery device for aquaculture, comprising a bottom plate 1, a support frame 2 is fixed to the top of the bottom plate 1, a dispersion mechanism 3 is provided on the top of the support frame 2, and delivery mechanisms 4 are provided on both sides of the top of the bottom plate 1;

[0031] The dispersion mechanism 3 includes a fry bin 301, the bottom end of the fry bin 301 is fixed to the top of the support frame 2, an inner cylinder 302 is provided inside the fry bin 301, a hydraulic rod 303 is fixed to the top end of the inner cylinder 302, and a pressure plate 304 is fixed to the output end of the hydraulic rod 303, and air supply bins 306 are fixed on both sides of the bottom end of the fry bin 301, and baffles 307 are sliding on the side close to the air supply bin 306. The air supply bins 306 on both sides are connected to the inner cylinder 302 through the air supply pipe 1 308, and a hole bin 309 is fixed to the bottom end of the fry bin 301, and an air supply pipe 2 310 is fixed inside the hole bin 309, and the top of the air supply pipe 2 310 is fixed to the bottom end of the inner cylinder 302.

[0032] The support frame 2 can provide a fixation for the fry bin 301 to prevent the fry bin 301 containing the fry to be released from falling and causing the fry to directly enter the breeding pond. After the fry to be released are poured into the area between the fry bin 301 and the inner cylinder 302, the pressure plate 304 can be moved downward by the push of the hydraulic rod 303, and the electric control valve on the surface of the pressure plate 304 can be used to press the air below the pressure plate 304 into the air supply pipe 1 308 and the air supply pipe 2 310. The air moving along the air supply pipe 1 308 can enter the air supply bin 306, and the air moving along the air supply pipe 2 310 can enter the hole bin 309. Therefore, as the pressure plate 304 gradually moves downward, the air supply bin 306 and the hole bin 30 9 can continue to have bubbles in the area within a certain period of time, thereby increasing the oxygen content of the water in the area where the air supply bin 306 and the hole bin 309 are located, and further making the fry in the fry bin 301 that originally swam aimlessly move closer to the area where the air supply bin 306 and the hole bin 309 are located. Since the area of ​​the air supply bin 306 is relatively small, the number of fry that can be attracted and accommodated is relatively small. In summary, when a large number of fry need to be released in batches, the number of fry released in each round can be guaranteed to be relatively uniform, preventing the situation where the air supply bin 306 is full of fry in the later stage as the water inside the fry bin 301 decreases due to the small number of fry entering the air supply bin 306 in the early stage.

[0033] Please see the attached Figure 4 and attached Figure 7 , rafts 5 are fixed to the front and rear parts of the bottom of the bottom plate 1, and one-way valve 1 311 is fixed to the bottom of the air supply bin 306 on both sides. The inside of the one-way valve 1 311 on both sides is fixed to the bottom of the outer side of the air supply pipe 1 308, and a one-way valve 2 312 is fixed to the outer side of the bottom of the air supply pipe 2 310.

[0034] By means of the raft 5 and the related chains, the bottom plate 1 and the connected components can be placed in a certain area of ​​the breeding pond, and part of the area of ​​the delivery mechanism 4 can be ensured to be always submerged in water, so as to prevent the subsequent delivery mechanism 4 from being unable to effectively provide the water in the breeding pond to the fry. The one-way valve 1 311 and the one-way valve 2 312 can respectively prevent the water inside the fry bin 301 from entering the inner tube 302 along the air supply pipe 1 308 and the air supply pipe 2 310. At the same time, the one-way valve 1 311 and the one-way valve 2 312 are at the same horizontal height to avoid the air under the pressure plate 304 from being unable to be discharged along the air supply pipe 1 308 and the air supply pipe 2 310 at the same time due to the pressure difference.

[0035] Please see the attached Figure 3 A spring 313 is fixed to the bottom end of the inner cylinder 302, a disc 314 is fixed to the top of the spring 313, movable rods 315 are fixed on both sides of the bottom end of the disc 314, the bottom ends of the movable rods 315 on both sides pass through the inner cylinder 302 and rotate with a rotating plate 316, the bottom ends of the rotating plates 316 on both sides rotate with shields 317, and the bottom ends of the shields 317 on both sides slide on the bottom end of the fry bin 301.

[0036] The spring 313 can move the disc 314 up a certain distance, and then the movable rod 315 can rotate the rotating plate 316 to drive the shield plate 317 to move closer to each other along the fry warehouse 301. On the contrary, when the hydraulic rod 303 drives the pressure plate 304 to slowly move down a certain distance, the pressure plate 304 can contact the disc 314. At this time, under the continued push of the hydraulic rod 303, the movable rod 315 and the rotating plate 316 can move in the opposite direction and cause the shield plate 317 to gradually block the connection between the air supply warehouse 306 and the fry warehouse 301. At this time, some of the fry that are attracted to the air supply warehouse 306 by the increase in oxygen content can be isolated outside the fry warehouse 301, preventing these fry from re-swimming into the fry warehouse 301 when they are subsequently acted upon by the releasing mechanism 4.

[0037] Please see the attached Figure 3 and attached Figure 8 A perforated plate 318 is fixed at the lower inner part of the air supply bin 306 on both sides, and a guide rod 319 is fixed at the front and rear sides of the top of the baffle 307 on both sides. A guide frame 320 is sliding on the outside of the multiple guide rods 319, and the guide frames 320 on both sides are fixed at the front and rear parts of the close side of the air supply bin 306 on both sides on the far side.

[0038] The orifice plate 318 can more finely divide the bubbles entering the air supply chamber 306, thereby further improving the oxygen content of the water body, and at the same time preventing the fry from entering the air supply pipe 308. In addition, the guide rod 319 and the guide frame 320 can limit the movement direction of the baffle 307 to prevent the baffle 307 from being skewed or horizontally displaced and unable to effectively block the water body and fry inside the air supply chamber 306.

[0039] Please see the attached Figure 3 The outer side of the pressing plate 304 slides inside the inner cylinder 302 , a cross 305 is fixed on the outer side of the inner cylinder 302 , and the outer side of the cross 305 is fixed on the inside of the fry bin 301 .

[0040] Through the contact between the pressure plate 304 and the inner cylinder 302 and the related sealing ring, it can be ensured that when the pressure plate 304 moves downward, the air below the pressure plate 304 cannot leak along the contact surface between the pressure plate 304 and the inner cylinder 302. At the same time, when the pressure plate 304 moves upward with the hydraulic rod 303, the electric control valve on the surface of the pressure plate 304 can be actively opened to replenish the air in the area below the pressure plate 304. In addition, the inner cylinder 302 can be effectively fixed by the cross 305 to prevent the inner cylinder 302 from moving downward and causing the water inside the fry bin 301 to enter the inner cylinder 302.

[0041] Please see the attached Figure 2 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 9The delivery mechanism 4 includes a box body 401, the bottom ends of the box body 401 are respectively fixed to the two sides of the top of the bottom plate 1, and a delivery port 402 is opened on the front and rear sides of both ends of the box bodies 401 on both sides. A movable frame 403 is slidably provided on the front and rear sides of the boxes 401 on both sides. A U-shaped frame 404 is fixed in the middle of the front and rear ends of the boxes 401 on both sides. A plurality of U-shaped frames 404 are fixed with servo motors 405 on the side away from the box body 401. The output ends of the plurality of servo motors 405 pass through the U-shaped frame 404 and are fixed with incomplete gears 406. The outer sides of the plurality of incomplete gears 406 are meshed with tooth plates 407. The plurality of tooth plates 407 are fixed with horizontal Plate 408, multiple horizontal plates 408 are fixed with water supply boxes 409 on the top, multiple water supply boxes 409 are all slid with water storage bins 410 at one end away from the U-shaped frame 404, multiple water storage bins 410 are all slid with slide plates 411, multiple slide plates 411 are fixed with push rods 412 at the bottom ends, multiple push rods 412 bottom ends pass through the water storage bin 410 and rotate with push plates 413, multiple push plates 413 bottom ends are rotated on both sides of the bottom end of the movable frame 403, water inlet 1 414 is opened on the upper front and rear sides of the box bodies 401 on both sides, and water inlet 2 415 is opened on the side of the water storage bins 410 close to the U-shaped frame 404.

[0042] The bottom plate 1 can be used to fix the box body 401, and the lower area of ​​the box body 401 can be placed below the water surface of the breeding pond with the cooperation of the floating raft 5. At this time, as the servo motor 405 is started, the incomplete gear 406 can be rotated in one direction. Since there are convex teeth only in a part of the outer side of the incomplete gear 406, and there are convex teeth on both sides of the inner side of the tooth plate 407 that mesh with it, when the incomplete gear 406 rotates, the tooth plate 407 can make a reciprocating linear motion. Among them, when the tooth plate 407 moves downward, the water supply box 409 can be moved synchronously through the cross plate 408, and when the tooth plate 407 moves downward to the extreme position, the water supply box 409 can be submerged in water. As the tooth plate 407 moves upward, the water supply box 409 and the box body 401 are connected. , the water storage tank 410 is in contact, so a small amount of water in the breeding pond can be held and moved upward with the cooperation of the box body 401 and the water storage tank 410 until the water supply box 409 moves up to the area where the water inlet 1 414 and the water inlet 2 415 are located. At this time, the water in the breeding pond can enter the box body 401 and the water storage tank 410 along the water inlet 1 414 and the water inlet 2 415 respectively through the preset openings on the surface of the water supply box 409. With the continuous movement of the servo motor 405, the water in the breeding pond that flows into the box body 401 multiple times can gradually change the temperature and water quality of the water transferred from the air supply tank 306 to the box body 401, thereby reducing the possibility of stress reaction of the fry after subsequent release. At the same time, when the water level in the box body 401 rises, The water that enters the water storage tank 410 along the water inlet 2 415 can exert a thrust on the slide plate 411. When the water above the slide plate 411 accumulates to a certain amount, the thrust exerted by the slide plate 411 on the lightweight movable frame 403 through the push rod 412 and the push plate 1 413 can be greater than the resistance of the water in the box 401 to the movable frame 403. At this time, the movable frames 403 on the front and rear sides can move closer to the delivery port 402 in their respective directions along the box 401 as the push plate 1 413 rotates. When the two side areas of the movable frame 403 are staggered with the delivery port 402, the water inside the box 401 that is higher than the water level of the breeding pond no longer blocks the movement of the movable frame 403. Therefore, the front and rear movable frames 403 can accelerate away from each other, and with the cooperation of the water height difference, Most of the fry and water are pushed out of the box body 401 from the release port 402 in a short time, so that the purpose of completing the release of fry in this round can be achieved after the fry adapt to the water quality and temperature of the breeding pond. The push of the movable frame 403 can reduce the probability of the fry being injured during the release. At the same time, as the slide plate 411 moves down to the gap in the lower area of ​​the water storage tank 410, the water above the slide plate 411 can be quickly discharged from the gap. Then, after the slide plate 411, the push rod 412 and the push plate 1 413 lose the external force, the movable frame 403 can be pushed closer to each other through the release port 402 with the help of the water in the breeding pond, and then the push plate 1 413, the push rod 412 and the slide plate 411 can be returned, thereby preparing for the next round of release.Furthermore, the actual internal volume of the water storage tank 410 must be determined based on the resistance exerted by the water inside the tank 401 when the tank 401 moves, ensuring that the slide plate 411, push plate 1 413, etc. can push the movable frame 403 to move under the action of the water inside the water storage tank 410. Furthermore, since only a portion of the tank 401 is submerged in water, and the air supply tank 306 and water supply box 409 have limited volumes, the amount of water inside the tank 401 is also relatively limited during placement, thus preventing the push plate 1 413 from being unable to push the movable frame 403 to move.

[0043] Please see the attached Figure 9 The front and rear side incomplete gears 406 rotate on the sides close to the front and rear side U-shaped frames 404 respectively, and the front and rear side tooth plates 407 slide on the sides close to the front and rear side U-shaped frames 404 respectively.

[0044] The U-shaped frame 404 can limit and guide the incomplete gear 406 and the tooth plate 407 to prevent the incomplete gear 406 and the tooth plate 407 from deviating during movement and affecting normal use.

[0045] Please see the attached Figure 6 and attached Figure 9 , blocks 416 are fixed on the front and rear sides of the two side boxes 401, and multiple U-shaped frames 404 are fixed with sealed compartments 417 on the side away from the box 401. The servo motors 405 are respectively located inside the sealed compartments 417, and the front and rear water storage tanks 410 are respectively fixed on the front and rear ends of the two side boxes 401 on the close side.

[0046] The block 416 can prevent the front and rear movable frames 403 from directly contacting the front wall or the rear wall of the box 401 when approaching the delivery port 402 in their respective directions, thereby preventing the water in the breeding pond from entering the area between the U-shaped movable frame 403 and the box 401, and further preventing the movable frame 403 from being unable to return to the initial position. The sealing chamber 417 can shield the servo motor 405 to prevent the servo motor 405 from being damaged after contacting the water. In addition, the box 401 can provide fixation for the water storage tank 410 to ensure that the slide plate 411, push rod 412, etc. connected thereto can work normally.

[0047] Please see the attached Figure 5 , Attachment Figure 7 and attached Figure 8 A guide bin 418 is fixed on the outer side of the air supply bin 306 on both sides, and a vertical plate 419 is fixed on the bottom end of the baffle 307 on both sides. The bottom ends of the vertical plates 419 on both sides pass through the guide bin 418. A push plate 2 420 is rotated on the side away from the top end of the movable frame 403 on both sides, and the top end of the push plate 2 420 rotates on the front and rear sides of the bottom end of the vertical plates 419 on both sides respectively.

[0048] When the movable frame 403 moves away from each other, the push plate 2 420 can rotate and drive the vertical plate 419 to move down along the guide bin 418, thereby driving the baffle 307 to move synchronously so as to no longer block the connection between the air supply bin 306 and the guide bin 418. In conjunction with the inclined orifice plate 318, the isolated fry inside the air supply bin 306 can enter the guide bin 418 with the water body to be subsequently transferred to the box body 401. At the same time, when the movable frame 403 returns, the push plate 2 420, the vertical plate 419 and the baffle 307 can return to the initial position, thereby cooperating with the dispersion mechanism 3 to attract some fry into the air supply bin 306 again.

[0049] Please see the attached Figure 6 and attached Figure 8 There is a sliding inclined plate 421 on the lower side of the guide bins 418 on both sides, and a limiting frame 422 is fixed on the side close to the top of the movable frame 403 on both sides. There are rotating push plates 423 inside the multiple limiting frames 422, and there are rotating rollers 424 on the tops of the multiple push plates 423. There are counterweight blocks 425 fixed on the side of the multiple push plates 423 close to the movable frame 403.

[0050] The inclined plate 421 can be limited and guided by the guide bin 418, and when the movable frames 403 move away from each other, since the push plate three 423 moves synchronously with the movable frame 403 through the limit frame 422, the inclined push plate three 423 can be rotated to a certain angle under the action of gravity and then blocked by the limit frame 422. At this time, the inclined plate 421 can also move down along the guide bin 418 under the action of gravity and block the water outlet at the bottom of the guide bin 418, so as to cooperate with the push plate two 420, the vertical plate 419 and the baffle 307 to temporarily block the fry and water inside the air supply bin 306 in the guide bin 418, and as the water in the breeding pond pushes the movable frame 403 back, the push plates three 423 on the front and rear sides can move ahead of the movable frame 403 The movable frame 403 contacts and rotates upward, and with the cooperation of the roller 424, the inclined plate 421 can be pushed upward relatively smoothly. As the movable frames 403 on the front and rear sides contact each other, the fry and water in the guide bin 418 can also fall into the box body 401 through the outlet left after the inclined plate 421 moves upward, thereby completing the batch transfer from the fry bin 301 to the box body 401 to carry out the process of adaptive conversion of water quality and water temperature. In addition, the weight on one side of the push plate three 423 can be increased by the counterweight block 425 to prevent the push plate three 423 from accidentally rotating to a vertical state, which will cause the inclined plate 421 to be unable to move downward, and in conjunction with the small amount of breeding pond water flowing into the box body 401, the fry can be prevented from being injured when entering the box body 401.

[0051] Working principle: When in use, a large amount of fry to be released is poured into the space between the fry bin 301 and the inner tube 302, and then the hydraulic rod 303 is started. The air below the pressure plate 304 is gradually pressurized by the downward movement of the pressure plate 304 and the electrically controlled valve on its surface, and flows along the air supply pipe 1 308 and the air supply pipe 2 310, and then enters the air supply bin 306 and the hole bin 309 after passing through the one-way valve 1 311 and the one-way valve 2 312 to form bubbles. The bubbles are divided into multiple small bubbles by cooperating with the orifice plate 318 and the holes on the surface of the hole bin 309, thereby increasing the oxygen content of the water body in the area where the air supply bin 306 and the hole bin 309 are located, so that the fry swimming in the fry bin 301 can be attracted to the vicinity of the air supply bin 306 and the hole bin 309, and at the same time When the hydraulic rod 303 continues to move downward, the movable rod 315 can also move when the pressure plate 304 contacts the disc 314. Since the length of the rotating plate 316 is fixed, the rotating plate 316 can rotate to push the shield plate 317 to gradually move along the fry bin 301 to above the air supply bin 306, thereby separating the air supply bin 306 from the fry bin 301, ensuring that when the subsequent baffle 307 moves downward, the fry in the air supply bin 306 can enter the guide bin 418 with the water body, and the remaining fry in the fry bin 301 will be separated again and enter the air supply bin 306 when the hydraulic rod 303, the pressure plate 304 and the shield plate 317 move in the next round, thereby achieving the purpose of ensuring that the number of fry released in each round is relatively uniform, and preventing the problem of single release of fry. In the case of too many or too few seedlings, the incomplete gear 406 can be rotated by the servo motor 405, and then the tooth plate 407 can be made to do reciprocating linear motion in the vertical direction under the cooperation of the U-shaped frame 404, so as to continuously submerge the water supply box 409 in water through the cross plate 408 to hold the water in the breeding pond, and as the tooth plate 407 moves upward, the water supply box 409 can pour the breeding pond water from the water inlet 1 414 and the water inlet 2 415 into the box body 401 and the water storage tank 410 respectively through its surface openings, wherein the water flowing into the water storage tank 410 can apply a thrust to the slide plate 411, so that the slide plate 411 pushes the push plate 1 413 to rotate through the push rod 412, and at the same time, as the push plate 1 413 rotates, it can apply a thrust to the movable frame 403 to make The movable frame 403 moves outward along the box body 401, and as the movable frame 403 approaches the delivery port 402, due to the grooves on both sides of the movable frame 403, the movable frame 403 no longer completely blocks the delivery port 402, and the water in the breeding pond that is submerged in the lower area of ​​the box body 401 can flow into the box body 401 through the gap between the delivery port 402 and the movable frame 403, and then the inflowing breeding pond water can push the movable frame 403 to overcome the thrust applied by the push plate 1 413 and the slide plate 411 and return to the initial position. During the reciprocating motion of the movable frame 403, when the movable frames 403 on the front and rear sides move away from each other, the push plate 2 420 connected to the movable frame 403 can rotate and drive the baffle 307 to move downward through the vertical plate 419.At this time, the isolated fry and water in the air supply chamber 306 can flow into the guide chamber 418 through the channel exposed after the baffle 307 moves. At the same time, the limit frame 422 connected to the movable frame 403 can drive the push plate 3 423 and the roller 424 to move away from each other. Therefore, the inclined plate 421 that has lost its support can move down along the guide chamber 418 and block the water outlet at the bottom of the guide chamber 418, thereby achieving the purpose of transferring the fry and temporarily trapping them in the guide chamber 418. On the contrary, as the movable frame 403 approaches and contacts each other, the push plate 2 420 and the push plate 3 423 can be reversed to make the baffle 307 and the inclined plate 421 move up. At this time, the fry and water inside the guide chamber 418 can fall into the box body 401 with a small amount of breeding pond water through the water outlet, and with the continuous movement of the servo motor 405, the incomplete gear 406 and the tooth plate 407, the breeding pond The water in the breeding pond can be intermittently replenished into the box 401 to allow the fry to gradually adapt to the water temperature and water quality of the breeding pond, and to prevent the fry from experiencing a stress reaction due to the large difference in water temperature and water quality. In addition, since the water inside the box 401 can block the movement of the movable frame 403 to a certain extent, as the water supply box 409 moves multiple times, the water accumulated above the slide 411 can exert sufficient thrust on the push rod 412 through the slide 411, thereby allowing the lightweight movable frame 403 to overcome the resistance exerted by the water inside the box 401 and move again. At this time, since the water level inside the box 401 is higher than the water level in the breeding pond, when the movable frame 403 passes through its surface groove and is misaligned with the release port 402 again, most of the fry inside the box 401 can be pushed out of the box 401 along with the water by the movable frame 403, so as to achieve the purpose of stable release of the fry.
