Description

Technical Field

[0001] The utility model relates to the technical field of aquatic seedling placement, in particular to a seedling placement device used in aquaculture. Background Art

[0002] As an important part of my country's economy, the healthy development of the aquaculture industry is of great significance to increasing farmers' income, meeting the consumption needs of urban and rural residents and maintaining ecological balance. The rational release of fish fry, as the basis for the development of the aquaculture industry, is crucial to the sustainable development of the industry.

[0003] Aquaculture seedlings are usually packed in aquatic seedling bags (inflatable transport bags) and transported in special foam boxes. The seedlings are then released by taking out the seedling bags and directly placing them in the breeding pond without opening them. This is because the temperature of the water in the seedling bags will be different from that in the breeding pond after transportation, and by allowing the closed seedling bags to float on the water, the temperature of the water inside can gradually become consistent with the water temperature in the pond, thereby reducing the stimulation of environmental changes on the seedlings and ensuring the survival rate of the seedlings. However, in the above method, the process of releasing the seedling bags and subsequently opening the seedling bags to release the seedlings requires workers to go down to the pond, so the convenience of releasing the seedlings cannot be guaranteed.

[0004] After searching, the Chinese utility model patent with publication number CN215836549U discloses a fry placement device for aquaculture that is easy to adjust the position, including a box and a pitch adjustment structure, the surface of the box is provided with a pitch adjustment structure, the pitch adjustment structure includes a slider, the slider is welded to the top of the box, the inner wall of the slider is threadedly connected with a screw, the surface of the screw is rotatably connected with a square plate, the bottom of the square plate is welded with a support frame, the surface of the screw is fixedly connected with a second gear, the surface of the second gear is meshed with a first gear, the surface of the first gear is fixedly connected with a rocker, and the side of the support frame close to the slider is welded with a fixed rod. This application prevents the fry from falling to the shore by moving the box to the water surface for fry placement, but the water environment of the aquatic fry during transportation is necessarily different from the water environment in the breeding pond. Therefore, if the fry are directly placed in the breeding water body after transportation without transition, it is easy to cause stress response of the fry due to the difference in water temperature, thereby reducing its survival rate.

[0025] Example 1

[0026] Refer to the attached Figure 1-3The present application provides a seedling delivery device for aquaculture, comprising a base 1 and a delivery basin 9, wherein the delivery basin 9 is used to hold seedlings and transition water temperature. When the device is used, the delivery basin 9 can be moved to the surface of the aquaculture pond, and its bottom can be immersed in the water body, while ensuring that its basin mouth is above the water surface. In this case, the transport water contained in the delivery basin 9 can exchange heat with the pond water, so that the temperature of the former can gradually become consistent with the latter, so that the water temperature in the delivery basin 9 can change slowly, so that the seedlings can gradually adapt to the pond water temperature, and avoid the drastic temperature change. The top of the base 1 is fixedly connected with a fixed cylinder 3. The diameter of the base 1 is larger than that of the fixed cylinder 3. Therefore, the base 1 can provide sufficient support for the fixed cylinder 3. A support rod 7 is provided on the top of one side of the fixed cylinder 3, and a driving mechanism is provided inside the fixed cylinder 3. The driving mechanism adjusts the height of the delivery basin 9 through the support rod 7. The angle of the support rod 7 can be adjusted through the driving mechanism to make the delivery basin 9 rise and fall. Since the delivery basin 9 is rotatably connected to the bracket 8, the transport water in the delivery basin 9 can be used as the delivery basin 9. The counterweight is added to keep the axis always in a state of vertically upward direction, so as to avoid the water inside the delivery basin 9 being spilled during the adjustment process, and eventually causing the seedlings to be damaged. One end of the support rod 7 is fixedly connected to the bracket 8, and the delivery basin 9 is rotatably connected to the inner side of the bracket 8. The support rod 7 includes a first rod sleeve 701, a rod body 702 and a second rod sleeve 703. The first rod sleeve 701 and the second rod sleeve 703 are respectively sleeved on the outside of the two ends of the rod body 702. The second rod sleeve 703 is used to flip the delivery basin 9. The second rod sleeve 703 is driven to rotate by the reduction motor 15. The bracket 8 can drive the delivery basin 9 to rotate and tip it over, and then the seedlings in the delivery basin 9 can be delivered to the breeding pond. In this process, since the delivery basin 9 is on the water surface, the water body will provide buoyancy for the delivery basin 9. Therefore, by using the buoyancy to lift the delivery basin 9, the flipping can be made more stable without further deflection due to the rotational connection with the bracket 8. In addition, the reduction motor 15 can flip the delivery basin 9 at a relatively slow speed, thereby avoiding water vibration or splashing due to centrifugal force, thereby making the delivery process more friendly to the seedlings.

[0027] Preferably, the driving mechanism includes a threaded rod 11, which is rotatably connected to the middle of the inner wall at the bottom end of the fixed cylinder 3. A circular opening is opened at the top of the fixed cylinder 3, and the top of the fixed cylinder 3 is fixedly connected to a casing at the outside of the circular opening. A driving motor is fixedly connected to the inner wall of the top of the casing. The driving motor can be a stepper motor. The stepper motor can accurately control the rotation angle, so that the deflection angle of the support rod 7 can be accurately adjusted, thereby achieving the effect of accurately adjusting the position of the delivery basin 9. Therefore, seedlings in multiple seedling bags can be delivered to the delivery basin 9, and then the immersion depth of the delivery basin 9 in the pond water can be adaptively adjusted according to the water surface height in the delivery basin 9, so as to improve the efficiency of the transition water temperature process. The top of the threaded rod 11 extends to the outside of the fixed cylinder 3 at the circular opening, and the bottom end of the output shaft of the driving motor is fixedly connected to the threaded rod 11.

[0028] Preferably, the rod body of the threaded rod 11 is externally threadedly connected with a threaded sleeve 13, and the outside of the threaded sleeve 13 is equidistantly fixedly connected with three connecting rods 12, and the outside of the fixed tube 3 is equidistantly provided with three strip openings, and the three connecting rods 12 extend to the outside of the fixed tube 3 at the three strip openings respectively, and the strip openings can guide the threaded sleeve 13 through the connecting rod 12, that is, limit the rotation of the threaded sleeve 13 so that it can only move in the vertical direction under the rotation drive of the threaded rod 11. Therefore, when the threaded sleeve 13 drives the first bearing 2 to move, the support rod 7 can be pushed and pulled by the support rod 10 and the sliding sleeve 6 to make it deflect to adjust the height of the delivery basin 9. The outsides of the three connecting rods 12 are fixedly connected with the same first bearing 2, and a support rod 10 is fixedly connected to one side of the first bearing 2, and the top of the support rod 10 is rotatably connected to the sliding sleeve 6. The first bearing 2 includes a first inner ring and a first outer ring, and a plurality of first steel balls are arranged between the two. The first inner ring is fixedly connected to the three connecting rods 12, and the first outer ring is fixedly connected to the support rod 10.

[0029] Preferably, a second bearing 5 is fixedly connected to the top end of the outer side of the fixed cylinder 3, a handle 4 is fixedly connected to one side of the second bearing 5, the second bearing 5 includes a second inner ring and a second outer ring, a plurality of second steel balls are arranged therebetween, the second inner ring is fixedly connected to the fixed cylinder 3, the second outer ring is connected to the handle 4 and the first rod sleeve 701, the first rod sleeve 701 is rotatably connected to the other side of the second bearing 5, the sliding sleeve 6 is sleeved on the outside of the first rod sleeve 701, when the support rod 10 is raised or lowered, the support rod 7 is pushed and pulled by the sliding sleeve 6, and the rotational connection of the sliding sleeve 6 with the support rod 10 and the sliding connection with the support rod 7 can adapt to the angle change when the support rod 7 is deflected. An electric push rod 14 is fixedly connected to the inner wall of one side of the first rod sleeve 701, and one end of the piston rod of the electric push rod 14 is fixedly connected to the rod body 702. The electric push rod 14 can be used to push the rod body 702 to move, and then the position of the delivery basin 9 can be adjusted in distance. At the same time, turning the handle 4 can also allow the support rod 7 to drive the delivery basin 9 to deflect and move, so as to adjust the position within a fan-shaped range. In this way, the position of the delivery basin 9 can be adjusted in a larger range, so that it can carry out the seedling delivery work in a larger range. The other end of the rod body 702 is fixedly connected to the reduction motor 15, and the output shaft of the reduction motor 15 is fixedly connected to the inner wall of the second rod sleeve 703, and the bracket 8 is fixedly connected to one end of the second rod sleeve 703.

[0030] Working principle: when the device is used, it can be placed on the bank of the breeding pond, then the seedling bag is taken out of the transport box and untied, and then the seedlings and the transport water in it are loaded into the delivery basin 9, and then the driving motor can be started. The driving motor can drive the threaded rod 11 to rotate so that the threaded sleeve 13 can move in the vertical direction. The threaded sleeve 13 drives the first bearing 2 to move through the connecting rod 12. The first bearing 2 drives the sliding sleeve 6 to move through the support rod 10, so that the support rod 7 can be pushed or pulled to deflect it, and the support rod 7 can be adjusted to deflect downward, so the support rod 7 can drive the delivery basin 9 to deflect through the bracket 8 until the bottom of the delivery basin 9 is immersed in the pond water. At this time, the transport water in the delivery basin 9 can exchange heat with the water in the pond, so that the water temperature of the former gradually becomes consistent with the water temperature of the latter, thereby providing a suitable water temperature transition for the seedlings;

[0031] In the above process, since the support 8 and the delivery basin 9 are in an active state, the transport water contained in the delivery basin 9 can provide a counterweight for the delivery basin 9, so that the delivery basin 9 is always in a state where the axis is vertical, thereby preventing the water from spilling and causing damage to the seedlings;

[0032] After a certain period of transition, when the water temperature inside and outside the delivery basin 9 is consistent, the seedlings can be released. During this process, the support rod 7 can drive the bracket 8 and the delivery basin 9 to move within a fan-shaped range by turning the handle 4, and the rod body 702 can be moved by starting the electric push rod 14, thereby adjusting the total length of the support rod 7, so that the delivery basin 9 has a larger adjustment range. In addition, the reduction motor 15 can be used to control the delivery basin 9 to slowly flip, so that the seedlings can enter the water body. Combined with the handle 4, the electric push rod 14 and the reduction motor 15, the range of seedling release can be expanded and the delivery process can be more uniform.

[0033] Example 2

[0034] Refer to the attached Figure 4 The present application provides a seedling delivery device for aquaculture. Compared with the first embodiment, in order to more stably adjust the delivery basin 9, a plurality of pipe sleeves 16 are fixedly connected to the top of the support rod 7. The inner sides of the plurality of pipe sleeves 16 are provided with a same delivery pipe 17. The bottom end of the delivery pipe 17 extends to the inside of the delivery basin 9. By setting the delivery pipe 17, the position of the delivery basin 9 in the pond water can be adjusted first, and then the delivery pipe 17 can be used to load the seedlings together with the transport water into the delivery basin 9. The significance of this is that it can prevent the delivery basin 9 from being positioned in the previous suspended state. When the position is adjusted, the delivery basin 9 will vibrate due to the transmission between the parts, which will cause the water body to oscillate and cause the phenomenon of spillage; in addition, in order to adapt to the length change of the support rod 7, the delivery tube 17 can also adopt a telescopic tube formed by multiple pipe sections that are mutually nested; in addition, although the bottom end of the delivery tube 17 extends into the delivery basin 9, when the delivery basin 9 is turned over to release the seedlings, it does not need to be rotated 360 degrees to achieve the delivery effect, but only needs to be rotated about 90 degrees. Therefore, the state of the delivery tube 17 extending into the delivery basin 9 will not affect its tipping adjustment process.

[0035] Working principle: When using this device, you can first control the driving motor to adjust the position of the delivery basin 9, and then put the seedlings and the water for transportation into the delivery basin 9 through the delivery tube 17. At this time, since the water can provide buoyancy for the delivery basin 9, the position of the delivery basin 9 can be adjusted more stably later, and it can also avoid the phenomenon that when the height of the delivery basin 9 is adjusted by using the support rod 7, the water inside it will be shaken or spilled, thereby causing damage to the seedlings.

[0036] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
