Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to an automatic aquatic plant planting device for crayfish. Background Technology

[0002] In crayfish farming, aquatic plants play a crucial role, serving as a key guarantee for successful cultivation. They provide crayfish with safe habitats and hiding places, effectively reducing the risk of cannibalism, and also contribute to improved survival rates and quality by purifying water and providing natural food.

[0003] However, the current common practice of artificially introducing aquatic plants in crayfish farming has several prominent problems, seriously affecting the full utilization of these plants' functions. Firstly, it's difficult to precisely control the distribution density of aquatic plants during artificial introduction, often resulting in uneven distribution. Some areas are overly dense, leading to poor ventilation and light penetration, and the plants polluting the water after decay; other areas are too sparse, failing to provide sufficient shelter and food for crayfish, directly destroying a suitable growth environment. Secondly, artificial introduction requires a significant investment of manpower and time. In large-scale ponds, this is not only labor-intensive but also extremely inefficient, significantly increasing overall farming costs. Thirdly, manual operation cannot accurately adjust the introduction based on the water depth differences in different areas of the pond. Most aquatic plants have specific depth requirements for growth; improper introduction depth will prevent the plants from taking root and surviving, and even if some survive, their growth will be slow, ultimately greatly reducing the actual effectiveness of the aquatic plant introduction and failing to achieve the expected auxiliary effects in farming.

[0004] Therefore, this application designs an automatic crayfish aquatic plant planting device to solve the above technical problems. Summary of the Invention

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Aquatic plants are crucial in crayfish farming. Often referred to as "underwater forests," they are a core element for successful crayfish farming. Their introduction aims to support crayfish survival, growth, and water quality control, requiring careful attention to key aspects such as species selection, planting timing, density control, and management. I. The Core Purpose of Aquatic Plant Introduction 1. Provide habitat and hiding places to reduce stress and self-harm: Crayfish are timid by nature and like to hide. They have no defense when molting and are easily preyed upon by their own kind or natural enemies. The roots, stems and leaves of aquatic plants (especially submerged plants) form dense underwater spaces that can serve as "safe houses" for crayfish to live in and move around at night. During molting, crayfish can hide in aquatic plants to avoid being attacked and improve their molting survival rate. During extreme weather such as high temperatures and heavy rain, aquatic plants can alleviate the stress response caused by sudden environmental changes and reduce the number of crayfish that climb ashore to escape.

[0021] 2. Regulating water quality and maintaining the ecological balance of aquatic bodies: Aquatic plants are natural "water purifiers" and "water stabilizers": They absorb excess nitrogen (ammonia nitrogen, nitrite), phosphorus, and other nutrients in the water, inhibit the outbreak of harmful algae such as blue-green algae and euglena, and prevent "algal blooms"; they increase the dissolved oxygen content of the water: they produce oxygen through photosynthesis, especially in the high-temperature season, which can compensate for the insufficiency of mechanical aeration and prevent crayfish from surfacing due to lack of oxygen; they stabilize the pH value of the water: the photosynthesis of aquatic plants consumes carbon dioxide, reducing water acidification and maintaining the pH in a suitable range of 7.5-8.5; they adsorb suspended impurities, improve water transparency, and provide a clear growth environment for crayfish.

[0022] 3. As a natural food source, supplementing nutrition: Most aquatic plants (such as Elodea, Hydrilla verticillata, and Vallisneria natans) are high-quality natural food for crayfish. Aquatic plants are rich in vitamins, minerals, and dietary fiber, which can supplement the nutritional deficiencies of artificial feed and promote the intestinal health of crayfish. After crayfish eat aquatic plants, their growth rate and meat quality can be improved, the feed conversion ratio can be reduced, and the breeding cost can be reduced. Plankton and microorganisms will adhere to the surface of aquatic plants, further enriching the food sources of crayfish.

[0023] 4. Regulate water temperature and create a suitable growth environment: The suitable water temperature for crayfish growth is 20-30℃. High temperature (above 32℃) or low temperature (below 15℃) will inhibit growth. In summer, the branches and leaves of aquatic plants block sunlight and reduce the heat absorption of the water, which can lower the underwater temperature by 2-3℃ and avoid heat stress for crayfish. In winter, the decomposition of aquatic plants can release a small amount of heat and at the same time provide a hiding place for crayfish to overwinter, thus improving the survival rate of overwintering.

[0024] 5. Promotes gonadal development and improves reproductive efficiency in crayfish: A high-quality aquatic plant environment can improve the growth status of crayfish and promote gonadal maturation: Female crayfish lay eggs and carry eggs in aquatic plants, which can protect the fertilized eggs from being washed away by the water flow, while providing a stable dissolved oxygen environment and improving the hatching rate; sufficient aquatic plants can reduce fighting among crayfish during the breeding season and improve the survival rate of parent crayfish and the survival rate of larvae.

[0025] II. Key Requirements for Aquatic Plant Placement 1. When selecting aquatic plants, choose varieties that match the aquaculture model, prioritizing a combination of submerged and emergent plants: Aquatic plants should be selected based on the principles of "easy survival, tolerance to trampling, non-polluting the water, and palatable to crayfish." Three core types of plants are recommended, avoiding the use of a single species. Submerged plants are the core, including *Elodea nuttallii*, *Hydrilla verticillata*, and *Vallisneria natans*; emergent plants are supplementary, purifying the water near the shore and providing a sheltered transition zone between land and water; however, excessive planting should be avoided to prevent shading.

[0026] 2. Planting timing should be phased to match the crayfish growth cycle: Autumn and winter planting: Core planting is Elodea nuttallii, when the water temperature is 10-15℃, aquatic plants easily take root and survive, and can grow slowly in winter, providing habitat and food for crayfish larvae in spring; Spring replanting: If Elodea nuttallii coverage is insufficient, Hydrilla verticillata can be replanted, as crayfish activity increases at this time and sufficient aquatic plants are needed for cover; Summer maintenance: Focus on maintaining Hydrilla verticillata, promptly remove old branches and leaves of Elodea nuttallii to prevent rotting of the plants in high temperatures; If aquatic plants are insufficient, a small amount of Vallisneria natans can be replanted.

[0027] 3. Density control requires a "sparse and uniform" approach, leaving sufficient space for activity: If the aquatic plant coverage is too low, it will not be effective; if it is too high, it will lead to water hypoxia and plant decay. The core principle is to control the aquatic plant coverage of the entire pond at 50%-60%, distributed in "strips" or "patches," reserving 30%-40% of empty water for crayfish activity and water exchange: Submerged plants: Elodea should be planted with a row spacing of 2-3 meters and a plant spacing of 1-1.5 meters, with 3-5 plants per hole; Hydrilla verticillata should be propagated at a density of 3-5 plants per square meter; Emergent plants: plant along the shallow beach at the edge of the pond, with a width of 1-2 meters and a gap every 5-10 meters to avoid blocking water flow.

[0028] 4. Choose scientific planting methods to improve survival rate: Submerged plants (Elodea nuttallii, Hydrilla verticillata): Use the "cutting method", cut the stems of the aquatic plants into 15-20 cm lengths, insert them into the silt at the bottom of the pond 5-10 cm, ensuring that the roots are in contact with the silt. The planting depth should be such that the top of the aquatic plant protrudes 1-2 cm above the water surface; Vallisneria natans: Use the "sowing method", mix Vallisneria natans seeds with fine soil and sow them evenly in October or November, with a sowing rate of 0.5-1 kg per acre. Keep the water depth at 5-10 cm to facilitate seed germination; Emergent plants: Transplant seedlings of water hyacinth, reeds, etc. directly, root them in the silt at the edge of the pond, and control the water level at 10-20 cm to avoid submerging the seedlings.

[0029] Reference Figures 1 to 8 As shown, this embodiment provides an automatic crayfish aquatic plant planting device, including: The hull 1, as a carrier, can move automatically in the waters where crayfish are farmed; the width of the hull 1 is adjustable; the hull 1 is equipped with an adjustable adjustment platform 11. Storage mechanism 2 includes a storage component installed on the hull 1 for storing aquatic plants to be deployed; the storage component is connected to a transfer component for transferring aquatic plants. The delivery mechanism 3 includes a trimming component and a delivery component installed on the adjustment platform 11. The outlet of the trimming component is connected to the inlet of the delivery component, and the outlet of the transfer component can be connected to the trimming component. The trimming component trims the aquatic plants, and the trimmed aquatic plants enter the delivery component. The delivery component sends the trimmed aquatic plants to a set depth underwater and delivers the aquatic plants.

[0030] This invention discloses an automatic aquatic plant planting device for crayfish, which realizes automated and precise placement of aquatic plants, significantly reducing labor input, lowering the labor intensity of large-area aquaculture ponds, improving placement efficiency, and shortening placement operation time. It reduces overall aquaculture costs from both labor and time perspectives. Simultaneously, by precisely controlling the distribution density and placement depth of aquatic plants, it ensures stable growth of the plants, fully leveraging their core functions of purifying water quality, providing habitat, and offering natural food, creating a suitable growth environment for crayfish, thereby improving their survival rate and quality. The device uses an automatically moving hull 1 as its mobile carrier, allowing it to navigate autonomously within the aquaculture area. The hull 1 has an adjustable width to adapt to aquaculture ponds of different sizes. An adjustable platform 11 is mounted on the hull 1, providing a flexible base for the placement mechanism 3 to adjust its installation and operating position. This allows the placement mechanism 3 to move flexibly within the aquaculture area, achieving large-scale and uniform placement of aquatic plants, avoiding the localized dense or sparse distribution problems caused by manual placement, ensuring water ventilation and light penetration, reducing the risk of aquatic plant decay and water pollution, and providing comprehensive habitat and natural food for crayfish. The storage mechanism 2 includes a storage component and a transfer component mounted on the hull 1. The storage component is used to store aquatic plants to be released in batches. The transfer component is connected to the storage component and can orderly transfer the stored aquatic plants to the release mechanism 3, ensuring a continuous supply for the release operation and providing a foundation for automated aquatic plant release. The release mechanism 3 is mounted on the adjustment platform 11 and consists of a trimming component and a release component. The outlet of the transfer component is connected to the trimming component, and the outlet of the trimming component is connected to the inlet of the release component. The trimming component tidies up the aquatic plants to prevent them from piling up due to messy shapes and further optimizes the distribution density. The release component accurately releases the trimmed aquatic plants to a set depth underwater to complete the release operation. It adapts to the water depth differences in different areas and the water depth requirements for aquatic plant growth, ensuring that the aquatic plants take root, survive, and grow normally, and fully leveraging the auxiliary role of aquatic plants in aquaculture.

[0031] In one embodiment of the present invention, the hull 1 adopts automated driving technology and can also be operated remotely to realize automated operation; the principle of automatic control or remote control can be referred to the working principle of existing unmanned ships or drones, which is an existing technical solution and will not be described in detail here.

[0032] The design is further optimized. The trimming component includes a cylinder 31 mounted on the adjustment platform 11. Inside the cylinder 31 are a support module and a trimming module. The support module is positioned below the trimming component and can move vertically up and down. A transfer component loads aquatic plants into the cylinder 31, which then falls onto the support module. The support module is adjusted to a set height, and the trimming component trims the aquatic plants. The cylinder 31 provides a closed and fixed working space for trimming aquatic plants. The support module supports the aquatic plants, preventing them from shifting or shaking during trimming, thus improving the trimming effect. During the loading of aquatic plants, the transfer component transfers the aquatic plants stored in the storage component to the cylinder 31, where they fall onto the support module. The support module is height-adjustable, allowing adjustment of the aquatic plant position according to different plant types and trimming requirements. This enables the trimming module to trim the plants more precisely, improving trimming quality and ensuring that the loaded aquatic plants meet growth requirements.

[0033] The design is further optimized. The trimming module includes two trimming screws 32 arranged parallel to each other on both sides of the cylinder 31. The two trimming screws 32 rotate synchronously and are connected to a trimming motor 33 located on the outer wall of the cylinder 31. Two symmetrically arranged trimming shears 34 are threaded between the two trimming screws 32, with their blades facing each other. After the support module moves the aquatic plants into position, trimming begins. During trimming, the trimming motor 33 drives the trimming screws 32 to rotate, causing the two trimming shears 34 to move relative to each other. The blades make horizontal cuts to the aquatic plants, resulting in fast and efficient trimming with clean cuts. This ensures that the trimmed aquatic plants have a neat shape, reduce damage, and promote their growth and function underwater.

[0034] The design is further optimized. The support module includes a support plate 35 that moves vertically within the cylinder 31, located below the trimming module. A connecting handle 36 is provided on the side wall of the support plate 35, extending out of the support plate 35 and connected to a support lifting rod 37 mounted on the adjustment platform 11. Aquatic plants falling onto the support plate 35 provide support, better distributing their weight and preventing localized damage from pressure, while also preventing them from falling through gaps in the support structure. The support lifting rod 37 drives the connecting handle 36 to raise and lower the support plate 35, precisely adjusting the height of the aquatic plants within the cylinder 31 to ensure the trimming module accurately targets the desired trimming area.

[0035] In a further optimized design, a limiting frame 39 is provided at the bottom of the cylinder 31, and a limiting ball 310 is rotatably connected to the limiting frame 39. The limiting ball 310 is slidably sleeved on the limiting lever 311, and the top end of the limiting lever 311 is perpendicularly fixed to the end of the connecting handle 36. When the support plate 35 moves to the outlet at the bottom of the cylinder 31, it can deflect downward under the drive of the limiting lever 311. When the support plate 35 moves to the bottom outlet of the cylinder 31, the limiting lever 311 drives the support plate 35 to deflect downward under the action of the limiting ball 310 and the limiting frame 39, so that the outlet of the cylinder 31 opens and the trimmed aquatic plants can be smoothly discharged from the bottom outlet of the cylinder 31, which facilitates the deployment of aquatic plants by the deployment component without the need for additional power. It can be opened after reaching the position. After deployment, the output end of the support lifting rod 37 rises, the positional relationship between the hinge shaft 38 and the limiting frame 39 changes, the angle of the limiting lever 311 deflects, so that the support plate 35 returns to rise and closes the support plate 35 again, which facilitates the next trimming of aquatic plants.

[0036] In one embodiment of the present invention, a first limiting groove 334 is provided on the cylinder 31 in a longitudinal direction, and the connecting handle 36 passes through the first limiting groove 334 and slides in the first limiting groove 334 to limit the support plate 35.

[0037] The design is further optimized. The deployment component includes a clamping module and a lifting module connected by a transmission mechanism. The clamping module can move up and down along the cylinder 31 under the drive of the lifting module. During aquatic plant trimming, the clamping module is located between the support module and the trimming module. During deployment, the clamping module extends out of the cylinder 31 under the drive of the lifting module. When the aquatic plants fall onto the support plate 35, the clamping module clamps the aquatic plants, ensuring stable fixation during trimming and preventing movement that could affect the trimming effect. After trimming, the support plate 35 and the clamping component descend together, moving the aquatic plants downwards. When the support plate 35 is opened, the clamping module continues to descend under the drive of the lifting module, exiting the cylinder 31 until the set deployment depth. This adapts to the different water depth requirements for aquatic plant growth, significantly improving the survival rate of aquatic plants. At the same time, the clamping module can also fix the aquatic plants when they sink in the water. Compared to free-fall deployment, this prevents the aquatic plants from being impacted by the water flow and deviating from the target deployment position during entry into the water, ensuring deployment accuracy.

[0038] The scheme is further optimized. The clamping module includes a clamping base 312 that is connected to the lifting module. A waterproof motor 313 is installed on the clamping base 312. The output end of the waterproof motor 313 is connected to a drive gear 314. The drive gear 314 meshes with two symmetrically arranged driven gears 315. An arc-shaped clamping arm 316 is fixed to the outer wall of the driven gear 315. The two clamping arms 316 are symmetrically arranged. The clamping base 312 rises and falls under the drive of the lifting assembly, which in turn raises and lowers the entire clamping module. It also serves as the mounting base for the waterproof motor 313 and the clamping arms 316. The waterproof motor 313 is waterproof and can operate underwater. By controlling the speed and torque of the waterproof motor 313, the clamping force can be adjusted according to the thickness and toughness of the aquatic plants, adapting to different types of aquatic plants and preventing damage from excessive clamping or detachment from excessive looseness, thus improving reliability. The arc-shaped design of the clamping arms 316 better conforms to the aquatic plants, providing a larger clamping area and more even force distribution, effectively preventing slippage or damage during clamping and improving the stability and reliability of the clamping. During operation, the waterproof motor 313 drives the drive gear 314 to rotate, which in turn drives the two driven gears 315 to rotate, causing the two clamping arms 316 to move relative to each other, thus clamping and releasing the aquatic plants.

[0039] In one embodiment of the present invention, a second limiting groove 335 is provided on the side wall of the cylinder 31 in a longitudinal direction, and the clamping seat 312 is slidably connected in the second limiting groove 335.

[0040] Further optimizing the design, the lifting module includes a first lifting tube 317 and a second lifting tube 318 fixed to the adjustment platform 11. The first lifting tube 317 contains a retractable guide rod 319, and a clamping seat 312 is limited and connected to the guide rod 319. A lifting screw 320 is rotatably connected to the second lifting tube 318, and a lifting block 321 is threaded onto the lifting screw 320. A transmission rod 322 is provided between the lifting block 321 and the clamping seat 312. The lifting screw 320 rotates under the drive of the output shaft of the lifting motor 330, causing the lifting block 321 to move up and down. The transmission rod 322 drives the clamping seat 312 to rise and fall, achieving precise lifting control of the clamping module. The guide rod 319 provides guidance for the lifting of the clamping seat 312, ensuring stability. Simultaneously, the guide rod 319 is retractable, allowing for greater descent depth of the clamping seat 312, accommodating deeper aquatic plant deployment. During operation, first connect the transmission rod 322 to the clamping seat 312. The lifting motor 330 drives the lifting block 321 to descend, which in turn lowers the clamping seat 312 to the set first depth. Then, disconnect the transmission rod 322 from the clamping seat 312; at this point, the clamping seat 312 and guide rod 319 are self-locked. Next, start the telescopic motor 331, which rotates the telescopic screw 332, causing the telescopic outer rod 333 to descend. This, in turn, lowers the clamping seat 312 locked to the telescopic outer rod 333 until the set aquatic plant placement depth is reached. This design allows for expansion of the aquatic plant placement depth to meet the needs of different aquaculture areas. Retrieval is achieved by reversing the process; details are omitted here.

[0041] In one embodiment of the present invention, a third limiting groove 336 and a fourth limiting groove 337 are provided on the first lifting tube 317 in a longitudinal direction. The third limiting groove 336 serves as a movement limit for the clamping seat 312, while the fourth limiting groove 337 serves as a limit for the outer rod of the telescopic rod, so that the outer rod of the telescopic rod 333 can only be raised and lowered and cannot be rotated.

[0042] In one embodiment of the present invention, a fifth limiting groove 338 arranged longitudinally is also provided on the first lifting block 321, and the transmission rod 322 slides in the fifth limiting groove 338 to limit the transmission rod 322.

[0043] In one embodiment of the present invention, a sixth limiting groove 339 is provided on the second lifting tube 318 in a longitudinal direction, and the transmission rod 322 slides in the sixth limiting groove 339.

[0044] In a further optimized design, the clamping base 312 is provided with a clearance groove 323, in which a permanent magnet block 324 slides elastically. A movable tooth block 326 is fixedly connected to one end of the permanent magnet block 324 facing the guide rod 319. The movable tooth block 326 is detachably connected to the limiting toothed rack 327 embedded on the guide rod 319. A connecting groove 328 is provided at the end of the transmission rod 322, in which an electromagnet 329 is provided. The electromagnet 329 and the permanent magnet block 324 can be attracted together. When the electromagnet 329 is energized, the permanent magnet block 324 is attracted to slide towards the electromagnet 329 in the clearance groove 323, causing the movable tooth block 326 to separate from the limiting rack 327. The clamping seat 312 can slide freely on the guide rod 319. At the same time, the permanent magnet part enters the connecting groove 328, which can serve as a connection structure between the transmission rod 322 and the clamping seat 312. The clamping seat 312 can be raised and lowered through the transmission rod 322. When the electromagnet 329 is de-energized, under the elastic action of the snap-fit ​​spring 325, the movable tooth block 326 engages with the limiting rack 327 to fix the position of the clamping seat 312. At the same time, the permanent magnet disengages from the connecting groove 328, and the transmission rod 322 and the clamping seat 312 lose connection and will not affect each other. This achieves flexible control and precise positioning during the raising and lowering process of the clamping seat 312, improving the accuracy of deployment.

[0045] In one embodiment of the present invention, a seventh limiting groove 340 is provided on the telescopic outer rod 333 in a longitudinal direction, and a limiting rack 327 is embedded in the seventh limiting groove 340.

[0046] The solution has been further optimized. The transfer component includes a liftable module that raises the aquatic plants stored in the storage component and transfers them into the transfer module. The transfer module then delivers the aquatic plants into the inlet of the cylinder 31. The lifting module can raise the aquatic plants in the storage component to a suitable height, facilitating the transfer module to deliver the aquatic plants into the cylinder 31. This ensures a smooth transfer of aquatic plants from storage to trimming, guaranteeing the continuity and efficiency of the entire aquatic plant deployment process and reducing the labor intensity of manual handling.

[0047] In one embodiment of the present invention, the discharge assembly includes a storage plate 21 disposed on the hull 1. Push plates 23 are slidably disposed at both ends of the storage plate 21. The two push plates 23 move towards the middle, pushing the aquatic plants on the storage plate 21 towards the lifting module in the middle, so as to ensure that the aquatic plants are continuously transported.

[0048] In one embodiment of the present invention, a limiting side plate 22 is provided on the side of the storage plate 21 away from the delivery mechanism 3 to limit the movement of the two push plates 23.

[0049] In one embodiment of the present invention, the lifting module includes a liftable lifting frame 24, which can move up and down between the storage plate 21 and the transfer module, and send aquatic plants into the transfer module through a plurality of first conveying rollers 25.

[0050] In one embodiment of the present invention, the transfer module includes a horizontal transfer frame 26, on which a plurality of second conveying rollers 27 are provided. The first conveying roller 25 delivers the aquatic plants to the second conveying rollers 27, and then moves them to the inlet of the cylinder 31 through the second conveying rollers 27.
