Description
Technical Field
[0001] This utility model relates to the field of vegetable planting technology, and more specifically, to a planting device for cultivating lettuce. Background Technology
[0002] Lettuce, a popular vegetable, is sweet and cool in nature. Its unique lactucin gives its stems and leaves a slightly bitter taste, yet it contains many amazing benefits. It acts like a "cleaner" for the body, clearing heat and refreshing the mind, dispelling fatigue and invigorating the spirit; it also acts like a natural "sleeping pill," exerting analgesic and hypnotic effects; it can lower cholesterol, protecting cardiovascular health, and has an auxiliary therapeutic effect on neurasthenia. It is rich in mannitol, which is diuretic, promotes blood circulation, cleanses the liver and gallbladder, and nourishes the stomach, providing comprehensive protection for bodily functions. In addition, it is rich in beta-carotene, various vitamins, dietary fiber, and trace elements, which not only help to achieve nutritional balance, but also enhance the digestion and absorption of protein and fat, and continuously improve gastrointestinal blood circulation. Regular consumption has many benefits.
[0003] The current method of cultivating lettuce mostly follows the traditional approach: first, furrows are dug on the seedbed, then water is poured into the furrows, and then lettuce seedlings are manually dug up with shovels and planted one by one into the furrows. After planting, the furrows are covered with soil and the seedbed is leveled. However, this traditional method is showing its drawbacks. From the perspective of land use, soil cultivation leads to frequent pests and diseases, causing damage to lettuce and raising the risk of pesticide residues. In terms of water resource management, the extensive irrigation model not only causes a lot of water resources to be wasted, but also makes it difficult to create precise and suitable growing conditions for each lettuce plant. Therefore, it needs to be improved and optimized. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a planting device for cultivating lettuce, which has the advantages of water saving and energy saving.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a planting device for cultivating lettuce, comprising a cultivation box, a connecting pipe fixedly connected to the left side of the cultivation box and extending into the inside of the cultivation box, a water outlet pipe fixedly installed at the inner end of the connecting pipe and the water outlet pipe communicating with each other, a limiting block fixedly installed on the inner wall of the water outlet pipe, an arc-shaped baffle slidably installed on the inner side of the limiting block and closely attached to the inner wall of the water outlet pipe, a connecting rod fixedly connected to the outer surface of the inner side of the arc-shaped baffle, a connecting ball fixedly installed at the end of the connecting rod, a hollow connecting rod fixedly installed on the outer surface of the connecting ball, a suspension cover fixedly installed at the end of the hollow connecting rod, a partition fixedly installed on the bottom side of the cultivation box and located on the right side of the water outlet pipe, and a connecting groove opened on the bottom side of the partition.
[0006] As a preferred embodiment of this utility model, a planting plate is fixedly installed between the partition and the inner wall of the right side of the cultivation box. Multiple arc-shaped plates are fixedly installed on the outer surface of the planting plate, and grooves are formed on both sides of the arc-shaped plates. A bracket is fixedly installed on the outer right side of the cultivation box, and a three-way pipe is fixedly installed on the outer surface of the bracket. A ventilation pipe is fixedly installed on the inner side of the arc-shaped plates, and all ventilation pipes extend through the cultivation box to the inner side of the three-way pipe and are interconnected. Ventilation slots are formed on both sides of the ventilation pipes, and the ventilation slots correspond one-to-one with the grooves formed on both sides of the arc-shaped plates. A nozzle is fixedly connected to the inner side of the ventilation pipe, and the nozzle passes through the grooves formed on both sides of the arc-shaped plates. Circular grooves are formed on the outer surface of the planting plate in a linear array with uniform spacing. A funnel is fixedly installed inside the circular grooves. A mixing box is fixedly installed on the outer right side of the cultivation box, and the connecting pipe of the three-way pipe extends into the mixing box.
[0007] As a preferred technical solution of this utility model, a limiting ring is fixedly installed on the top inner side of the water outlet pipe, and rubber protrusions are fixedly installed on the inner side of the limiting ring in a circumferential array.
[0008] As a preferred embodiment of this utility model, an air cushion is fixedly installed on the bottom side of the arc-shaped baffle, and multiple air cushions are fixedly installed on the bottom side of the arc-shaped baffle.
[0009] As a preferred embodiment of this utility model, a sponge ring is fixedly sleeved on the inner side of the sluice tube, and the sponge ring is located in the middle of the inner side of the sluice tube.
[0010] As a preferred embodiment of this utility model, the outer surface of the partition is provided with a plurality of connecting grooves, and the connecting grooves are located on the bottom side of the partition.
[0011] As a preferred embodiment of this invention, a base is fixedly installed on the bottom side of the incubator, and the base is fixedly installed around the bottom side of the incubator.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model involves water flowing into the incubation box through a connecting pipe, then adding water through the incubation box. The water then flows into the incubation box through a connecting groove. As the water level rises, when it gradually overflows the hollow connecting rod, the arc-shaped baffle gradually moves upward. When the water reaches the bottom of the suspension cover, the arc-shaped baffle isolates the connection between the connecting pipe and the incubation box, thus stopping the water injection into the incubation box. The arc-shaped baffle slides upward inside the limiting block, preventing any gaps in the isolation. This is suitable for cultivating lettuce. As the water is gradually consumed, the water level gradually drops, causing the suspended cover to move downwards. At the same time, the arc-shaped baffle moves downwards from the connection point between the water outlet pipe and the connecting pipe, allowing water to be refilled into the cultivation box. Compared to traditional devices, this device ensures sufficient and evenly distributed water within the device, providing a stable water environment for lettuce growth. Furthermore, the device automatically stops watering when the water level rises to prevent overflow and automatically restarts watering when the water level drops, precisely controlling the water volume. This not only meets the different water requirements of lettuce at different growth stages but also saves water and energy, greatly facilitating lettuce cultivation and management.
[0014] 2. This invention uses a mixing box to deliver a mixture of carbon dioxide and oxygen into the ventilation pipe through a three-way pipe. Then, the carbon dioxide and oxygen needed for growth are evenly sprayed onto the lettuce roots and stems inside the funnel through nozzles in a linear array on both sides. At the same time, the funnel allows water to directly enter the lettuce roots. Compared with traditional devices, this device, through the coordinated operation of the specially structured mixing box, three-way pipe, ventilation pipe, and nozzles, can accurately and evenly deliver the mixture of carbon dioxide and oxygen to the lettuce roots and stems, meeting their needs for photosynthesis and respiration, and promoting vigorous plant growth. On the other hand, the design of the funnel ensures that water can directly reach the lettuce roots, enabling the roots to absorb water efficiently, optimizing water use efficiency, and comprehensively supporting lettuce cultivation, improving yield and quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a planting device for cultivating lettuce, including a cultivation box 1. A connecting pipe 2 is fixedly connected to the left side of the cultivation box 1 and extends into the inside of the cultivation box 1. A water outlet pipe 3 is fixedly installed at the inner end of the connecting pipe 2 and the water outlet pipe 3 and the connecting pipe 2 are interconnected. A limiting block 4 is fixedly installed on the inner wall of the water outlet pipe 3. An arc-shaped baffle 5 is slidably installed on the inner side of the limiting block 4 and is in close contact with the inner wall of the water outlet pipe 3. A connecting rod 6 is fixedly connected to the outer surface of the inner side of the arc-shaped baffle 5. A connecting ball 7 is fixedly installed at the end of the connecting rod 6. A hollow connecting rod 8 is fixedly installed on the outer surface of the connecting ball 7. A suspension cover 9 is fixedly installed at the end of the hollow connecting rod 8. A partition 12 is fixedly installed on the bottom side of the cultivation box 1 and is located on the right side of the water outlet pipe 3. A connecting groove 13 is opened on the bottom side of the partition 12.
[0023] When the connecting pipe 2 is connected to an external water source, the water will flow through the connecting pipe 2 to the inside of the outlet pipe 3, and then add water into the cultivation box 1 through the outlet pipe 3. The water will then flow through the connecting groove 13 into the cultivation box 1. As the water level increases, when the water level gradually overflows the hollow connecting rod 8, the arc-shaped baffle 5 will gradually move upward. When the water overflows to the bottom of the suspension cover 9, the arc-shaped baffle 5 will isolate the connection between the connecting pipe 2 and the outlet pipe 3, thereby stopping the water from flowing into the cultivation box 1. The arc-shaped baffle 5 will slide upward inside the limiting block 4 to prevent the isolation from being incomplete. When the lettuce gradually consumes the water, the water level will gradually drop, causing the suspension cover 9 to gradually move downward. At the same time, the arc-shaped baffle 5 will move downward from the connection between the outlet pipe 3 and the connecting pipe 2, allowing water to flow back into the cultivation box 1.
[0024] Water flows through connecting pipe 2 to the inside of outlet pipe 3, and then water is added to the cultivation box 1 through outlet pipe 3. The water then flows into the cultivation box 1 through connecting groove 13. As the water level rises, when it gradually overflows the hollow connecting rod 8, the arc-shaped baffle 5 will gradually move upwards. When the water reaches the bottom of the suspension cover 9, the arc-shaped baffle 5 will disconnect the connection between connecting pipe 2 and outlet pipe 3, thus stopping the water from flowing into the cultivation box 1. The arc-shaped baffle 5 also slides upwards inside the limiting block 4, preventing any gaps in the connection. This process is crucial for the cultivation of lettuce. As the lettuce gradually consumes water, the water level gradually drops, causing the suspended cover 9 to move downwards. At the same time, the arc-shaped baffle 5 moves downwards from the connection point between the water outlet pipe 3 and the connecting pipe 2, allowing water to be refilled into the cultivation box 1. Compared to traditional devices, this device ensures sufficient and evenly distributed water within the device, providing a stable water environment for lettuce growth. Furthermore, the device can interrupt water injection when the water level rises to prevent overflow, and automatically restart water injection when the water level drops, precisely controlling the water volume. This not only meets the different water requirements of lettuce at different growth stages but also saves water and energy, greatly facilitating lettuce cultivation and management.
[0025] A planting plate 14 is fixedly installed between the partition 12 and the inner right wall of the incubator 1. Multiple arc-shaped plates 16 are fixedly installed on the outer surface of the planting plate 14, and grooves are opened on both sides of the arc-shaped plates 16. A bracket 22 is fixedly installed on the outer right side of the incubator 1. A three-way pipe 20 is fixedly installed on the outer surface of the bracket 22. A ventilation pipe 17 is fixedly installed on the inner side of the arc-shaped plates 16, and the ventilation pipes 17 all pass through the incubator 1 and extend to the inner side of the three-way pipe 20 and are interconnected. Ventilation slots 18 are opened on both sides of the ventilation pipes 17, and the ventilation slots 18 correspond one-to-one with the grooves opened on both sides of the arc-shaped plates 16. A nozzle 19 is fixedly connected to the inner side of the ventilation pipe 17, and the nozzle 19 passes through the grooves opened on both sides of the arc-shaped plates 16. Circular grooves 23 are opened on the outer surface of the planting plate 14 in a linear array and are evenly spaced. A funnel 24 is fixedly installed on the inner side of the circular grooves 23. A mixing box 21 is fixedly installed on the outer right side of the incubator 1, and the connecting pipe of the three-way pipe 20 extends into the mixing box 21.
[0026] When the mixing box 21 delivers a mixture of carbon dioxide and oxygen-rich gas into the ventilation pipe 17 through the three-way pipe 20, the carbon dioxide and oxygen required for growth are evenly sprayed into the root and stem of the lettuce inside the filter cylinder 24 through the nozzle 19 from the ventilation pipe 17 arranged in a linear array on both sides. At the same time, the filter cylinder 24 allows water to directly enter the root of the lettuce.
[0027] The mixed gas rich in carbon dioxide and oxygen is transported into the ventilation pipe 17 through the mixing box 21 via the three-way pipe 20. Then, the carbon dioxide and oxygen required for growth are evenly sprayed into the lettuce roots and stems inside the funnel 24 through the nozzles 19 from the ventilation pipes 17 arranged in a linear array on both sides. At the same time, the funnel 24 allows water to directly enter the lettuce roots. Compared with traditional devices, this device, through the coordinated operation of the specially structured mixing box 21, three-way pipe 20, ventilation pipe 17 and nozzles 19, can accurately and evenly deliver the mixed gas of carbon dioxide and oxygen to the lettuce roots and stems, meeting their needs for photosynthesis and respiration, and promoting vigorous plant growth. On the other hand, the design of the funnel 24 ensures that water can directly reach the lettuce roots, enabling the roots to absorb water efficiently, optimizing water use efficiency, and comprehensively supporting lettuce cultivation, improving yield and quality.
[0028] Among them, a limiting ring 10 is fixedly installed on the top inner side of the water outlet pipe 3, and rubber protrusions 11 are fixedly installed on the inner side of the limiting ring 10, and the rubber protrusions 11 are arranged in a circumferential array.
[0029] The rubber protrusions 11 are fixedly installed on the inner side of the limiting ring 10 and are arranged in a circumferential array. This can effectively limit the suspension cover 9, allowing the suspension cover 9 to move within a certain range.
[0030] Among them, an air cushion 15 is fixedly installed on the bottom side of the arc-shaped baffle 5, and multiple air cushions 15 are fixedly installed on the bottom side of the arc-shaped baffle 5.
[0031] Multiple air cushions 15 are fixedly installed on the bottom side of the arc-shaped baffle 5, which can effectively increase the upward levitation force of the arc-shaped baffle 5, thereby increasing the upward rate of the arc-shaped baffle 5.
[0032] A sponge ring 25 is fixedly sleeved on the inner side of the filament 24, and the sponge ring 25 is located in the middle of the inner side of the filament 24.
[0033] The sponge ring 25, located in the middle of the inner side of the funnel 24, can effectively provide support for the lettuce when it is being adjusted.
[0034] The partition 12 has multiple connecting grooves 13 on its outer surface, and the connecting grooves 13 are located on the bottom side of the partition 12.
[0035] By providing multiple connecting grooves 13 on the outer surface of the partition 12, the water flow can be made smoother after passing through the partition 12 and then through the connecting grooves 13, thus preventing water from splashing everywhere.
[0036] The incubator 1 has a base 26 fixedly installed on its bottom side, and the base 26 is fixedly installed around the bottom side of the incubator 1.
[0037] The base 26 is fixedly installed around the bottom of the incubator 1, which can effectively increase the stability of the entire device and prevent the entire device from being easily affected by external physical factors.
[0038] Working principle and usage process of this utility model:
[0039] When the connecting pipe 2 is connected to an external water source, the water will flow through the connecting pipe 2 to the inside of the outlet pipe 3, and then add water into the cultivation box 1 through the outlet pipe 3. The water will then flow through the connecting groove 13 into the cultivation box 1. As the water level increases, when the water level gradually overflows the hollow connecting rod 8, the arc-shaped baffle 5 will gradually move upward. When the water overflows to the bottom of the suspension cover 9, the arc-shaped baffle 5 will isolate the connection between the connecting pipe 2 and the outlet pipe 3, thereby stopping the water from flowing into the cultivation box 1. The arc-shaped baffle 5 will slide upward inside the limiting block 4 to prevent the isolation from being incomplete. When the lettuce gradually consumes the water, the water level will gradually drop, causing the suspension cover 9 to gradually move downward. At the same time, the arc-shaped baffle 5 will move downward from the connection between the outlet pipe 3 and the connecting pipe 2, allowing water to flow back into the cultivation box 1.
[0040] When the mixing box 21 delivers a mixture of carbon dioxide and oxygen-rich gas into the ventilation pipe 17 through the three-way pipe 20, the carbon dioxide and oxygen required for growth are evenly sprayed into the root and stem of the lettuce inside the filter cylinder 24 through the nozzle 19 from the ventilation pipe 17 arranged in a linear array on both sides. At the same time, the filter cylinder 24 allows water to directly enter the root of the lettuce.
