[0033] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figures 1 to 13 The present invention provides a technical solution of a cultivation device for cultivating aquatic plants: it includes a box body 1 and a cultivation tank 2, the interior of the box body 1 is movably connected to the outer wall of the cultivation tank 2, the upper part of the interior of the cultivation tank 2 is movably connected with a layer plate, the outer wall at the top of the layer plate is provided with a plurality of breeding ports 21, the interior of the breeding port 21 is movably plugged with a seedling shell 3, the interior of the seedling shell 3 is provided with a plurality of water inlet holes, the interior of the seedling shell 3 is movably plugged with a placing plate 31, the outer wall at the top of the placing plate 31 is fixedly connected with a floating plate 33, the outer wall at the top of the placing plate 31 is fixedly connected with two L-shaped pull rods 32, and the outer wall at the bottom of the seedling shell 3 is provided with a stirring mechanism.

[0035] Water enters the seedling placing shell 3 through the water inlet hole at the bottom of the seedling placing shell 3 to cultivate the aquatic plants inserted into the seedling placing shell 3. Since each aquatic plant is placed separately in the seedling placing shell 3, it is avoided that the roots of the aquatic plants are entangled during the cultivation and growth process, which affects the transplanting of the aquatic plants in the later stage. The entanglement of the roots of the aquatic plants is reduced accordingly, thereby improving the efficiency of the transplanting of the aquatic plants, preventing the roots from being pulled during the transplanting process, and increasing the survival rate of the transplanted aquatic plants.

[0036] Through the action of the floating plate 33, the placement plate 31 can be lifted up and always float on the water surface, so that the placement plate 31 drives the roots of the aquatic plants near the leaves to leak out of the water surface. By allowing part of the roots to be exposed to the water surface, a layer of microbial film will be formed on the surface of the roots exposed to the water surface. There is a mutually beneficial symbiotic relationship between these microorganisms and the plant roots. The microorganisms can help plants decompose organic matter, provide nutrients, and protect the roots from being invaded by pathogens, thereby avoiding that all the roots are completely immersed in water to affect the growth of aquatic plants, and correspondingly increasing the growth rate of aquatic plants and shortening the time for cultivating aquatic plants.

[0037] Embodiment 2, on the basis of embodiment 1, the stirring mechanism includes a mounting frame 6, the outer wall of the bottom of the seedling housing 3 is fixedly connected to the outer wall of the top of the mounting frame 6, a plurality of slots are provided at the bottom of the mounting frame 6, a magnetic block 2 62 is fixedly connected inside the slot, a mounting groove is provided on the outer wall of the bottom of the seedling housing 3, a mounting plate 7 is fixedly connected inside the mounting groove, an axial hole connected to the outer walls on both sides is provided on the mounting plate 7, a rotating shaft 71 is rotatably connected inside the axial hole, a knife holder 72 is fixedly connected to the outer wall of the rotating shaft 71, and a knife holder 72 is fixedly connected to the outer wall of the rotating shaft 71. The outer walls on both sides of the rack 72 are fixedly connected with a cutter 73, the interior of one end of the knife rack 72 is fixedly connected with a magnetic block 61, the outer wall at the bottom of the magnetic block 61 is connected to the outer wall at the top of the magnetic block 62 with the same polarity repelling each other, the outer wall of the mounting frame 6 is threadedly connected with a connecting ring 5, the outer wall at the bottom of the connecting ring 5 is fixedly connected with an intercepting net 51, the outer wall at the bottom of the intercepting net 51 is fixedly connected with a stabilizing plate 52, the outer wall at the bottom of the connecting ring 5 is fixedly connected with four connecting plates 53, and the outer walls at the bottom of the four connecting plates 53 are fixedly connected to the outer wall at the top of the stabilizing plate 52.

[0038] By rotating the trimmer 73 accordingly, the trimmer 73 rotates at the bottom of the seedling placing shell 3, so that the roots growing from the water inlet hole can be trimmed to avoid uneven nutrient absorption caused by excessive root growth. The corresponding trimming of the overly long roots can maintain the compactness and reasonable layout of the root structure, prevent the roots from being too long and entangled together, and further prevent some roots from being too developed while other parts are relatively weak, resulting in uneven overall growth of the plant. At the same time, after the roots are trimmed, the aquatic plants can better absorb and utilize nutrients, thereby promoting the overall growth of the plants.

[0039] By cooperating with the connecting plate 53 and the stabilizing plate 52, the intercepting net 51 can be fixed, which prevents the intercepting net 51 from moving when the water inside the cultivation tank 2 shakes and being stirred into the working area of ​​the scraper 73, thereby increasing the stability of the intercepting net 51 and improving the working efficiency of the scraper 73.

[0040] Embodiment 3, based on embodiment 2, the outer wall of the top of the rotating shaft 71 is fixedly connected with a threaded rod 43, the outer wall of the threaded rod 43 is threadedly connected with a push plate 44, the outer wall of the push plate 44 is fixedly connected with four sliders, and the outer wall of the slider is slidably connected with the inside of the strip groove 42.

[0041] By moving the push plate 44, the water inside the temporary storage shell 4 can be pushed, so that the water above the push plate 44 flows out through the strip groove 42, and the water inside the seedling releasing shell 3 will enter the bottom of the push plate 44 at the strip groove 42, so that the water inside the seedling releasing shell 3 can flow, avoiding the water inside the seedling releasing shell 3 in a static state, which will cause the roots of the aquatic plants to lack sufficient oxygen and restrict their breathing. The corresponding shaking of the water helps to increase the contact area between water and air, thereby increasing the dissolved oxygen content in the water. Adequate dissolved oxygen is very important for the cultivation of aquatic plants, which can promote their metabolism and growth rate, thereby improving the growth quality and yield of aquatic plants.

[0042] Embodiment 4, on the basis of embodiment 3, a temporary storage shell 4 is fixedly connected to the middle position at the lower part of the interior of the seedling placing shell 3, a protective cover 41 is fixedly connected to the outer wall of the temporary storage shell 4, a plurality of strip grooves 42 are provided on the outer wall of the temporary storage shell 4, a temporary storage box 8 is provided at the upper part of the interior of the temporary storage shell 4, a circular hole is provided at the lower part of the interior of the temporary storage box 8, a transfer rod 81 is slidably connected to the interior of the temporary storage shell 4, a stirring blade 82 is fixedly connected to the outer wall of the top of the two transfer rods 81, a groove is provided at the lower part of the outer wall of the transfer rod 81, a mounting plate 2 84 is rotatably connected to the interior of the groove, a reset spring 1 83 is fixedly connected to the outer wall of the top of the mounting plate 2 84, and a feed port 85 is provided on the outer wall of the transfer rod 81.

[0043] The nutrient solution in the temporary storage box 8 enters the interior of the transfer rod 81 through the feed port 85, and finally flows into the interior of the temporary storage shell 4 through the outflow hole at the bottom of the transfer rod 81. The water in the temporary storage shell 4 makes the nutrients flow, which can drive the nutrients into the interior of the seedling shell 3, avoiding adding the nutrient solution inside the cultivation tank 2 far away from the root system. Accordingly, the nutrient solution is directly added to the interior of the seedling shell 3, which is convenient for the root system to absorb the mechanical energy of the nutrient solution. By adding the nutrient solution in a small range, the root system can effectively absorb the nutrient solution while preventing the waste of the nutrient solution.

[0044] Embodiment 5, on the basis of embodiment 4, the outer wall of the mounting frame 6 is fixedly connected to the shell 9, the outer wall of the mounting frame 6 is provided with slide grooves 91 on both sides close to the shell 9, the outer walls at both ends of the shell 9 are provided with cavities, the interiors of the two cavities are fixedly connected with return springs three 95, the opposite ends of the two return springs three 95 are fixedly connected with T-shaped blocking blocks 93, the upper part of the inner wall of the slide groove 91 is fixedly connected with return springs two 94, the outer walls of the two return springs two 94 are fixedly connected to the L-shaped limit plate 92, the outer wall of the L-shaped limit plate 92 is in active contact with the outer wall of the T-shaped blocking block 93, the opposite side of the two L-shaped limit plates 92 is fixedly connected with a rubber pad, and the outer wall of one side of the L-shaped limit plate 92 is slidably connected to the interior of the slide groove 91.

[0045] By loosening the T-shaped blocking block 93, the T-shaped blocking block 93 can be pushed out from the inside of the cavity under the action of the reset spring three 95, and resisted under the L-shaped limit plate 92, so that the L-shaped limit plate 92 can be fixed. After the tool holder 72 is rotated to the position of the rubber pad on one side of the L-shaped limit plate 92, the same operation can be used to move the L-shaped limit plate 92 on the other side upwards, so that the tool holder 72 can be fixed, thereby making the movement of the tool holder 72 more flexible.

[0046] The working principle and use process of the present invention are as follows: when in use, first, add a certain amount of water into the inside of the cultivation tank 2, and then insert the seedling shell 3 into the inside of the breeding port 21, and then the aquatic plants to be cultivated can be inserted into the inside of the through hole on the placement plate 31, so that the roots of the aquatic plants are under the placement plate 31, thereby cultivating the aquatic plants.

[0047] After water is injected into the cultivation tank 2, after the seedling shell 3 is inserted into the cultivation tank 2 through the cultivation port 21, water can enter the seedling shell 3 through the water inlet hole at the bottom of the seedling shell 3 to cultivate the aquatic plants inserted into the seedling shell 3. Since each aquatic plant is placed separately in the seedling shell 3, the roots of the aquatic plants are prevented from being entangled during the cultivation and growth process, which would affect the transplanting of the aquatic plants in the later stage. The entanglement of the roots of the aquatic plants is correspondingly reduced, thereby improving the efficiency of the transplanting of the aquatic plants, preventing the roots from being pulled during the transplanting process, and increasing the survival rate of the transplanted aquatic plants.

[0048] By setting the floating plate 33 at the bottom of the placement plate 31, since the density of the floating plate 33 is less than the density of water, the floating plate 33 always floats on the water surface. Through the action of the floating plate 33, the placement plate 31 can be lifted up and always float on the water surface, so that the placement plate 31 drives the roots of the aquatic plants close to the leaves to leak out of the water surface. By allowing part of the roots to be exposed to the water surface, a layer of microbial film will be formed on the surface of the roots exposed to the water surface. There is a mutually beneficial symbiotic relationship between these microorganisms and the plant roots. The microorganisms can help plants decompose organic matter, provide nutrients, and protect the roots from being invaded by pathogens, thereby avoiding that all the roots are completely immersed in water to affect the growth of aquatic plants, and correspondingly improving the growth rate of aquatic plants and shortening the time for cultivating aquatic plants.

[0049] By the repulsion of like poles between the magnetic block 1 61 and the magnetic block 2 62, the magnetic block 1 61 can be pushed to rotate around the rotating shaft 71 as the axis, and then the magnetic block 1 61 is used to make the fixed part installed on the knife holder 72 rotate, and then the rotation of the magnetic block 1 61 can drive the knife holder 72 to rotate accordingly, and the rotation of the knife holder 72 can drive the cutter 73 to rotate accordingly, and the rotation of the cutter 73 at the bottom of the seedling shell 3 can trim the roots growing from the water inlet hole to avoid uneven nutrient absorption caused by excessive root growth. Accordingly, trimming the overly long roots can maintain the compactness and reasonable layout of the root structure, prevent the roots from being too long and entangled together, and further prevent some roots from being too developed while other parts are relatively weak, resulting in uneven overall growth of the plants. At the same time, after the roots are trimmed, the aquatic plants can better absorb and utilize nutrients, thereby promoting the overall growth of the plants.

[0050] By setting the interception net 51, the pruned roots will enter the interior of the interception net 51, avoiding the roots falling into the cultivation tank 2, making it inconvenient for the gardener to clean them mechanically, and correspondingly facilitating the gardener to clean them mechanically.

[0051] By cooperating with the connecting plate 53 and the stabilizing plate 52, the intercepting net 51 can be fixed, which prevents the intercepting net 51 from moving when the water inside the cultivation tank 2 shakes and being stirred into the working area of ​​the scraper 73, thereby increasing the stability of the intercepting net 51 and improving the working efficiency of the scraper 73.

[0052] When the knife holder 72 rotates inside the seedling shell 3, the surrounding water will be stirred, so that the water inside the cultivation tank 2 will flow, avoiding the water inside the cultivation tank 2 being static and the sediment easily accumulating at the bottom, which will affect the root growth of aquatic plants. The corresponding water shaking effectively prevents the accumulation of sediment, keeps the water clean and transparent, and is conducive to the healthy growth of aquatic plants.

[0053] The rotation of the rotating shaft 71 can drive the threaded rod 43 to rotate mechanically. Due to the threaded connection between the threaded rod 43 and the pushing plate 44, when the threaded rod 43 rotates, the pushing plate 44 can move upward or downward mechanically. Then, through the movement of the pushing plate 44, the water inside the temporary storage shell 4 can be pushed, so that the water above the pushing plate 44 flows out through the strip groove 42, and the water inside the seedling placing shell 3 will enter the bottom of the pushing plate 44 at the strip groove 42, so that the water inside the seedling placing shell 3 can flow, avoiding the water inside the seedling placing shell 3 in a static state, which will cause the roots of the aquatic plants to lack sufficient oxygen and have limited breathing. The corresponding shaking of the water helps to increase the contact area between water and air, thereby increasing the dissolved oxygen content in the water. Adequate dissolved oxygen is very important for the cultivation of aquatic plants, which can promote their metabolism and growth rate, thereby improving the growth quality and yield of aquatic plants.

[0054] It should be noted that the movement direction of the push plate 44 can be limited by the cooperation between the slider fixedly connected to the outer wall of the push plate 44 and the strip groove 42 .

[0055] By means of the protective cover 41 provided on the outer wall of the temporary storage shell 4, aquatic plants can be intercepted to prevent the roots of the aquatic plants from growing into the interior of the temporary storage shell 4. When the push plate 44 moves up and down, the roots of the aquatic plants will be affected, and the roots of the aquatic plants will be protected accordingly.

[0056] When the push plate 44 moves to the bottom of the transfer rod 81 and continues to move upward, the transfer rod 81 will be pushed to move upward accordingly. When the feed port 85 on the transfer rod 81 enters the interior of the temporary storage box 8, the nutrient solution inside the temporary storage box 8 can enter the interior of the transfer rod 81 from the feed port 85, and finally flow into the interior of the temporary storage shell 4 through the outflow hole at the bottom of the transfer rod 81. The water inside the temporary storage shell 4 makes it flow, which can drive the nutrient solution to enter the interior of the seedling shell 3, avoiding adding the nutrient solution inside the cultivation tank 2 far away from the root system. Accordingly, the nutrient solution is directly added to the interior of the seedling shell 3, which is convenient for the root system to absorb the mechanical energy of the nutrient solution. By adding the nutrient solution in a small range, the root system can effectively absorb the nutrient solution while preventing the waste of the nutrient solution.

[0057] It should be noted that the interior of the transmission rod 81 is hollow, and a one-way valve is provided at the outflow hole at the bottom of the transmission rod 81. The one-way valve is a prior art. The one-way valve allows the fluid to only flow along the water inlet, but the medium at the water outlet cannot flow back, commonly known as a one-way valve.

[0058] When the transfer rod 81 moves upward, the stirring blade 82 is driven to move upward as well. When the stirring blade 82 moves upward, it will encounter resistance from the nutrient solution. Under the action of the resistance, the stirring blade 82 will be pushed to rotate. Then, the stirring blade 82 will rotate inside the temporary storage box 8, thereby breaking the static state of the nutrient solution inside the temporary storage box 8, stirring the nutrient solution, and avoiding precipitation of the nutrient solution that enters the transfer rod 81, thereby maintaining the efficacy of the nutrient solution.

[0059] The gardener can push the T-shaped blocking block 93 by hand to move the T-shaped blocking block 93 to the cavity inside the shell 9. At this time, the fixing of the T-shaped blocking block 93 to the L-shaped limiting plate 92 is released, and the L-shaped limiting plate 92 is pushed upward to move the L-shaped limiting plate 92 to the upper part of the slide groove 91. Then the T-shaped blocking block 93 is released, and the T-shaped blocking block 93 can be pushed out from the cavity under the action of the reset spring 3 95 to resist under the L-shaped limiting plate 92, so that the L-shaped limiting plate 92 can be fixed. After the tool holder 72 rotates to the position of the rubber pad on one side of the L-shaped limiting plate 92, the same operation can be used to move the L-shaped limiting plate 92 on the other side upward to fix the tool holder 72, thereby making the movement of the tool holder 72 more flexible.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
