Description

Technical Field

[0001] The invention relates to the technical field of soilless cultivation, in particular to an aeroponic cultivation device. Background Art

[0002] In traditional agricultural production, common cultivation methods such as land cultivation and ordinary potted plants have many shortcomings. The utilization efficiency of land resources is low, and the density of plant planting is limited by the land area, making it difficult to achieve high-density planting. In addition, traditional cultivation has high requirements for soil conditions. The imbalance of soil nutrients affects the growth quality and yield of plants, and the irrigation and drainage system is relatively complex and inefficient, which easily causes waste of water resources and cannot accurately provide the plants with the required water and nutrients. With the continuous improvement of technology, aeroponic cultivation devices have appeared on the market.

[0003] The existing aeroponic cultivation devices have improved the efficiency and quality of planting to a certain extent, but there are still some problems. On the one hand, the structural design of some devices is not reasonable enough, which makes it difficult to mix the nutrient solution evenly, affecting the continuous absorption of nutrients by the plants. On the other hand, the cultivation capacity of existing devices is limited and cannot meet the needs of large-scale planting. For example, the tower-type aeroponic cultivation device is large in size, heavy in weight, and inconvenient to carry. It is impossible to increase the cultivation volume by increasing the planting height, which limits the further improvement of agricultural production efficiency. Although the upright aeroponic cultivation device can increase the cultivation volume by increasing the planting height, it requires the use of climbing tools during the planting and harvesting process. The operation is complicated and cumbersome, which increases the labor intensity and production costs, reduces production efficiency, and is difficult to adapt to the requirements of large-scale and intensive development of modern agriculture. There are also some three-dimensional rotary aeroponic cultivation devices on the market that can solve the above problems, but they are usually complex in structure, difficult to maintain in the later stage, and have high cost of use.

[0004] In summary, technical personnel in this field urgently need to develop an aeroponic cultivation device that can increase the cultivation volume by increasing the planting height, does not require the use of climbing tools during the planting and harvesting process, has a simple structure, and is easy to maintain.

[0007] Preferably, a hanging pin is provided at the top of the hanging column, and a clamping groove capable of corresponding hanging with the hanging pin is provided at the top of the trough-shaped plate.

[0008] Preferably, wedge-shaped plates for pressing the trough-shaped plate against the hanging column are provided on both the front and rear sides inside the fixing sleeve.

[0009] Preferably, strip-shaped ventilation grooves are provided at the positions near the bottom on both the left and right sides of the hanging column, and a shielding cover with an open top is provided at the position of the hanging column corresponding to the ventilation grooves.

[0010] Preferably, the notch end of the trough-shaped plate can correspondingly contact the shielding cover.

[0011] Preferably, a medicine adding box is communicated with one end of the water storage tank.

[0012] Preferably, two pipe joints are communicated with one end of the water storage tank.

[0013] Preferably, columns are tightly connected to both ends of the top of the water storage tank, right-angled brackets are installed on both the front and rear sides of the columns, and support blocks capable of corresponding adaptation to the notch of the trough-shaped plate are installed on the tops of the brackets; The support blocks on the same side of the two columns can jointly support a trough-shaped plate.

[0014] Preferably, among the two support blocks on one side of the water storage tank, a slot is provided on one of the support blocks, and a scraper is installed in the slot.

[0015] Preferably, a tool rest is hinged in the slot of the support block through a pin shaft. On one side of the tool rest corresponding to the pin shaft, there is an extension part that can contact the bottom of the slot of the support block correspondingly. A pin hole is provided on the extension part, and a limit pin is movably inserted at the position of the support block corresponding to the pin hole. The scraping knife plate is provided with an adjustment slot, and a locking screw is threadedly connected at the position of the tool rest corresponding to the adjustment slot.

[0016] Due to the adoption of the technical scheme as described above, the present invention has the following beneficial effects: (1) The structure of the present invention is simple. Through the optimized design and coordinated action of each component, the yield of the aeroponic cultivation device is improved, the use cost is reduced, and the cultivation and harvesting efficiency are increased. The submersible pump installed inside the water storage tank provides stable power for the nutrient solution circulation. The circulation water pipe is in an n-shaped structure, which can better cover the planting area and ensure the uniform delivery of the nutrient solution to each planting point. One end of the circulation water pipe is communicated with the water outlet of the submersible pump, and the switch valve at the other end can adjust the water flow state. By using the submersible pump, the full mixing of the nutrient solution and water is realized, and no additional stirring device is required, reducing the use cost and the difficulty of later maintenance.

[0017] (2) The uniform distribution of the planting mechanism of the present invention increases the planting quantity per unit area and improves the cultivation efficiency. The fixed sleeve is tightly connected to the top of the water storage tank, and the design of the return hole enables the excess water to flow back to the water storage tank, realizing the recycling of water resources and keeping the cultivation environment clean and stable. The trough-shaped plate and the hanging column enclose an atomization cavity, providing a good growth space for the plant roots, facilitating the aggregation and diffusion of water mist, improving the utilization efficiency of water and nutrients. Moreover, each planting mechanism atomization cavity operates independently, ensuring that the plants fully obtain water and nutrients and promoting their healthy growth. During planting and harvesting, the trough-shaped plate can be easily removed without the need to climb a ladder, improving the safety and convenience of planting and harvesting operations, reducing the labor intensity of the operators, and making the harvesting process efficient and smooth. In addition, a handle is installed at the bottom of the trough-shaped plate, facilitating the operators to stably control the movement and positioning of the trough-shaped plate, reducing the operation difficulty and safety risk, and fully considering the assembly relationship to ensure the smooth and unobstructed root removal operation, improving the overall performance and practicability of the device.

[0018] (3) The present invention further adds a hanging pin at the top of the hanging column, and a clamping groove is opened at the top of the trough-shaped plate, improving the convenience and stability of the fixing operation of the trough-shaped plate and facilitating quick hanging and assembly. A wedge-shaped plate is installed inside the fixed sleeve, enabling the trough-shaped plate to closely fit the hanging column and ensuring its stability. A ventilation groove and a shielding cover are arranged at the bottom of the hanging column, providing good ventilation conditions, adjusting the humidity and gas components in the atomization cavity, promoting the respiration and nutrient absorption of the plant roots, and at the same time preventing the water mist from escaping, ensuring the stability of the humidity of the cultivation environment and the normal operation of the surrounding facilities. The shielding cover can also limit the trough-shaped plate, reducing its height requirement, reducing the weight of the device, avoiding the entanglement of the plant roots with the atomization pipeline or the nozzle, and ensuring the normal growth of the plant roots and the stable operation of the system.

[0019] (4) The present invention further assembles columns at both ends of the top of the water storage tank, installs brackets on its front and back sides, and sets support blocks at the top, which are adapted to the notches of the trough-shaped plate, providing a stable support foundation for the trough-shaped plate. The operator can remove the trough-shaped plate and place it on the support block, adjust the height to a position suitable for operation, facilitating planting or harvesting operations, reducing labor intensity, improving work efficiency, and the trough-shaped plate is stably clamped with the support block, preventing accidental dropping and ensuring safe and reliable operation.

[0020] (5) In view of the problem that the roots of aeroponically cultivated plants are developed and inconvenient for harvesting, the present invention installs a scraper on the support block. Through the design of a hinged tool holder and a limit pin, the cutting angle and the extending length of the scraper can be flexibly adjusted, realizing the rapid separation of plant roots, significantly improving the harvesting efficiency, avoiding cumbersome root removal operations, reducing the risk of damage to plant roots and the cultivation environment, and maintaining the long-term stable operation of the system. At the same time, the tool holder can be flipped and retracted into the groove of the support block, avoiding accidental injury when idle, improving safety performance, prolonging the service life of the scraper, and reducing maintenance costs.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In this application, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection", and "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. Embodiment 1

[0026] Combined with the attached Figures 1 to 5 Figure, an aeroponic cultivation device includes a water storage tank 1, a circulating water pipe 2, and a planting mechanism. Among them, the water storage tank 1 is one of the core components of the entire device, and a certain amount of water and nutrient solution can be stored inside it to provide the necessary water and nutrient sources for plant growth. At the same time, the water storage tank 1 serves as the basic base of the entire device in this embodiment, and its stable structure provides a solid support for the entire aeroponic cultivation device, ensuring the stability of the overall structure, preventing the device from tipping over or other unstable phenomena during use, and guaranteeing the smooth progress of the cultivation process.

[0027] Inside the water storage tank 1, a submersible pump is installed. This submersible pump is a common standard device on the market and can provide stable power support for the circulation of the nutrient solution. The top of the water storage tank 1 is installed with a circulating water pipe 2 in an n-shaped structure. This special structural design enables the circulating water pipe 2 to better cover the planting area and ensures that the nutrient solution can be evenly delivered to each planting point. Both ends of the circulating water pipe 2 penetrate through the top of the water storage tank 1 and are tightly and firmly connected to the water storage tank 1, ensuring the tightness of the connection and avoiding problems such as liquid leakage, and ensuring the efficient operation of the entire circulation system.

[0028] One end of the circulating water pipe 2 is correspondingly connected to the water outlet of the submersible pump, enabling the submersible pump to effectively transport the water and nutrient solution in the water storage tank 1 into the circulating water pipe 2. The other end of the circulating water pipe 2 is equipped with a switching valve 3. By controlling the opening and closing of the switching valve 3, the water flow state of the circulating system can be conveniently adjusted. When it is necessary to mix the water and nutrient solution in the water storage tank 1, after adding the nutrient solution into the water storage tank 1, the submersible pump and the switching valve 3 are turned on, and the water in the water storage tank 1 will circulate between the circulating water pipe 2 and the water storage tank 1, thereby realizing the full mixing of the nutrient solution and water and providing a uniform nutrient supply for plant growth. By utilizing the existing submersible pump, there is no need to additionally equip a stirring device, which can effectively reduce the use cost and the difficulty of later maintenance.

[0029] It should be noted that during the normal cultivation process, in order to avoid unnecessary waste of nutrient solution and excessive operation of the circulating system, the switching valve 3 should be kept closed to ensure that the system is in an economical and efficient operation mode.

[0030] On the top of the water storage tank 1, at the position corresponding to the two ends of the circulating water pipe 2, a plurality of planting mechanisms are orderly installed at certain intervals. These planting mechanisms are evenly distributed, can make full use of the space, increase the planting quantity per unit area, and improve the cultivation efficiency.

[0031] The planting mechanism includes a fixed sleeve 4, a hanging column 5 and a trough-shaped plate 8, as shown in the appendix Figure 2 and 3 shown. The fixed sleeve 4 and the top of the water storage tank 1 adopt a fastening connection method to ensure the stability and sealing between the two. At the position of the top of the water storage tank 1 corresponding to the inner cavity of the fixed sleeve 4, a return hole is opened, and this design is of great significance. During the atomized cultivation process, the excess water generated in the planting mechanism can flow back into the water storage tank 1 along the return hole, realizing the effective recovery and recycling of water resources, avoiding the waste of water resources, and at the same time maintaining the cleanliness and stability of the cultivation environment.

[0032] The bottom of the hanging column 5 is firmly connected to the fixed sleeve 4, ensuring the stability of the hanging column 5 during use. The front and back sides of the hanging column 5 are designed with open ends, providing convenient conditions for the installation of internal components and gas circulation. Inside the hanging column 5, an atomization pipeline 6 is installed. The top of the atomization pipeline 6 corresponds precisely to the circulating water pipe 2 and is tightly connected, ensuring that water can flow smoothly from the circulating water pipe 2 to the atomization pipeline 6. The bottom of the atomization pipeline 6 is of a closed structure to prevent water leakage. On the pipe body of the atomization pipeline 6, a plurality of atomizing nozzles 7 are evenly distributed at equal intervals from top to bottom. The atomizing nozzles 7 are tightly connected to the atomization pipeline 6. When the switch valve 3 is in the closed state, the submersible pump is turned on, and the submersible pump can deliver water with a certain pressure to the circulating water pipe 2 and the atomization pipeline 6. After the water flows through the atomizing nozzles 7, it is evenly atomized into fine water mist particles and sprayed out, forming a uniform water mist, creating a good humid environment for plant growth and ensuring that plants can fully absorb water and nutrients. To further improve the atomization effect and coverage area, the multiple atomizing nozzles 7 on the atomization pipeline 6 are reasonably divided into two groups. The two groups of atomizing nozzles 7 are respectively installed on the front and back sides of the atomization pipeline 6, spraying on plants from different directions, realizing the all-round supply of water and nutrients.

[0033] Groove-shaped plates 8 are respectively buckled on the front and back sides of the hanging column 5. As shown in the appendix Figure 4 and 5 shown, the bottom of the groove-shaped plate 8 is inserted into the fixed sleeve 4, achieving a stable installation. The two groove-shaped plates 8 and the hanging column 5 together enclose an atomization cavity with only an open bottom. This atomization cavity provides a good growth space for plant roots and is also conducive to the aggregation and diffusion of atomized water mist, improving the utilization efficiency of water and nutrients. The groove-shaped plates 8 are provided with a plurality of inclined planting grooves 9 at equal intervals from top to bottom. These planting grooves 9 provide a suitable position for the fixation and growth of plants.

[0034] At the position corresponding to the bottom of the planting groove 9 on the groove-shaped plate 8, through holes are opened. This design enables the roots of plants to smoothly pass through the groove-shaped plate 8 and enter the atomization cavity surrounded by the groove-shaped plate 8 and the hanging column 5, fully absorbing the water and nutrients in the water mist sprayed by the atomizing nozzles 7 and ensuring the demand for nutrients during the growth process of plants.

[0035] It should be noted that the atomization cavity of each planting mechanism operates independently, which can effectively ensure that all plants on the groove-shaped plate 8 can obtain sufficient water and nutrients and thus can thrive.

[0036] As shown in the appendix Figure 1As shown, the trough-shaped plate 8 is arranged vertically, and its height can be 3 to 5 meters, which enables three-dimensional planting. Through this three-dimensional planting method, the space utilization rate is greatly improved, and batch planting can be carried out in a limited space, effectively solving the problem of large land occupation in traditional planting methods and realizing the efficient use of land resources.

[0037] Compared with the existing tower-type atomized cultivation device, this device has significant advantages in the cultivation quantity. Due to the large volume and heavy weight of the cultivation bed of the traditional tower-type atomized cultivation device, there are many inconveniences in manual handling. Considering the weight factor and handling safety, it is impossible to further increase the planting height, thus restricting the improvement of its cultivation quantity. In this embodiment, the trough-shaped plate 8 is only used to plant a row of plants, and the overall weight is relatively light. Whether it is installation during the cultivation process or disassembly during harvesting, it can be easily removed, with simple operation, greatly reducing the labor intensity and improving the work efficiency.

[0038] During the cultivation operation, first remove the trough-shaped plate 8 from the hanging column 5, and use the planting cotton to implant the plant seedlings into the planting groove 9 to ensure that the roots of the seedlings are stable and closely combined with the planting groove 9. Then, reinstall the trough-shaped plate 8 with the seedlings installed onto the corresponding hanging column 5 to make it firmly connected to the hanging column 5 and the fixed sleeve 4. According to the predetermined irrigation cycle, turn on the submersible pump, and the atomizing nozzle 7 will evenly spray water mist to provide continuous and stable water and nutrient supply for the planted plants. As the plants grow, their roots gradually pass through the through holes of the trough-shaped plate 8 and enter the atomizing cavity. The plant roots in the atomizing cavity can fully contact the water mist sprayed by the atomizing nozzle 7, thereby continuously absorbing the nutrients in it to support the healthy growth of the plants.

[0039] At the harvesting stage, the trough-shaped plate 8 can also be easily removed from the hanging column 5. At this time, the mature plants are removed together with the trough-shaped plate 8, which is convenient for unified harvesting. The operator can easily collect the plants on the entire trough-shaped plate 8 on the ground without the need to climb a ladder, which not only improves the safety of the harvesting operation but also greatly enhances the convenience of the operation, reduces the labor intensity of the operator, and makes the entire harvesting process more efficient and smooth. Embodiment 2

[0040] Combined with attached Figures 1 to 3 and 6, an aeroponic cultivation device. The aeroponic cultivation device described in this embodiment is optimized and improved on the basis of the structure of Embodiment 1. Specifically, a hanging pin 10 is added to the top of the hanging column 5. At the same time, a card slot 11 that can accurately correspond to the hanging pin 10 and achieve a firm connection is opened at the top of the trough-shaped plate 8, as shown in attached Figure 2 and 3Such a structural design is not only simple and clear, but also greatly improves the convenience and stability of the fixing operation of the grooved plate 8, making it convenient for the user to quickly complete the hanging and assembly work of the grooved plate 8.

[0041] Furthermore, in the inner space of the fixing sleeve 4, wedge-shaped plates 12 are respectively installed on the front and rear sides thereof, as shown in the attached Figure 6 As shown. When installing the trough plate 8, the operator can first align the slot 11 on the trough plate 8 with the hook pin 10, and then move the trough plate 8 vertically and smoothly downward along the guide of the fixing sleeve 4. During the downward movement of the trough plate 8, the wedge plate 12 can effectively play its role, forcing the trough plate 8 to gradually fit closely to the hook column 5. When the hook pin 10 is accurately hooked with the slot 11, the trough plate 8 is firmly fixed in the predetermined position, ensuring the stability and reliability of the trough plate 8 during the subsequent aeroponic cultivation process.

[0042] In addition, strip-shaped ventilation slots 13 are respectively provided at the positions near the bottom on the left and right sides of the hanging column 5. In order to prevent the water mist generated during the atomization process from escaping from the ventilation slots 13 and to ensure the ventilation effect, a shielding cover 14 with an open top is installed at the position corresponding to the ventilation slots 13 on the hanging column 5. The coordinated design of the ventilation slots 13 and the shielding cover 14 provides effective ventilation conditions for the atomization chamber formed by the grooved plate 8 and the hanging column 5. A good ventilation environment helps to regulate the humidity and gas composition in the atomization chamber, thereby promoting the respiration and nutrient absorption of the plant roots, and creating favorable conditions for the healthy growth of plants.

[0043] It should be emphasized that the location of the ventilation slot 13 is crucial. In order to prevent the water mist from drifting from the top opening of the shielding cover 14 to the outside during the atomization process, affecting the humidity stability of the cultivation environment and the normal operation of the surrounding facilities, the ventilation slot 13 should be opened as close as possible to the bottom edge of the hanging column 5. Such a layout design can minimize the possibility of water mist escaping while ensuring ventilation performance, ensuring the efficient operation and environmental friendliness of the aeroponic cultivation system.

[0044] When the grooved plate 8 is accurately buckled on the hanging column 5, the notch end of the grooved plate 8 can achieve close contact with the shielding cover 14. In this way, in addition to its main function of preventing water mist from drifting, the shielding cover 14 also cleverly assumes the task of limiting the grooved plate 8. Through this limiting effect, the displacement and shaking of the grooved plate 8 during installation and use are effectively limited, while the height requirement of the groove wall of the grooved plate 8 is reduced, thereby reducing the weight burden of the entire cultivation device. At the same time, this design also cleverly avoids the risk of plant roots being entangled with the atomizing pipe 6 or the atomizing nozzle 7 due to the planting trough 9 being too close to the atomizing nozzle 7, thereby ensuring the normal growth of the plant roots and the stable operation of the aeroponic cultivation system. Example 3

[0045] Combined with Figure 1, in this embodiment, the involved aeroponic cultivation device further expands and improves relevant functional components on the basis of the structure of Embodiment 1 or Embodiment 2. In particular, a medicine adding box 15 is added at one end of the water storage tank 1. This design enables the operator to conveniently add liquid fertilizer or nutrient solution into the water storage tank 1 through the medicine adding box 15 to meet the various nutrient requirements of plants at different growth stages and ensure sufficient and balanced nutrient supply for plant growth.

[0046] In addition, two pipe connectors 16 are connected to the same end of the water storage tank 1. Among these two pipe connectors 16, one is specifically used to connect the water inlet pipe, and its core function is to replenish water source for the water storage tank 1 to maintain sufficient water in the tank; the other pipe connector 16 is used to connect the drain pipe so as to drain the water in the water storage tank 1 when needed. For example, when detecting the components of the nutrient solution, part of the water sample can be extracted through the drain pipe, and then the nutrient content therein can be analyzed to timely adjust the formula and concentration of the nutrient solution according to the actual detection results to ensure that it always meets the optimal requirements of plant growth.

[0047] When installing the pipe connector 16 connected to the drain pipe, special attention should be paid to the rationality of its position. In order to ensure that the liquid in the water storage tank 1 can be emptied as much as possible when changing water or nutrients, the pipe connector 16 should be set as close as possible to the bottom edge of the water storage tank 1. In this way, when the drain valve is opened, the liquid in the water storage tank 1 can fully flow out under the action of gravity, avoiding liquid residue caused by too high position of the pipe connector 16, thus ensuring the thoroughness and effectiveness of the replacement operation and preventing the residual liquid from polluting the newly added nutrient solution or affecting the accuracy of its component ratio. Example 4

[0048] As shown Figures 7 to 9 In the aeroponic cultivation device described in this embodiment, on the basis of inheriting the structural characteristics of any one of Embodiments 1 to 3, some components are optimized in design and improved in function to enhance the operation convenience and working efficiency of the entire cultivation system.

[0049] Specifically, upright columns 17 are assembled at both ends of the top of the water storage tank 1 by means of fastening connection. Right-angled brackets 18 are respectively installed on the front and back sides of the upright columns 17, and support blocks 19 that can be precisely adapted to the notch of the trough-shaped plate 8 are arranged on the top of the brackets 18. The support blocks 19 on the two upright columns 17 on the same side cooperate with each other to jointly provide a stable support foundation for the trough-shaped plate 8.

[0050] When performing planting or harvesting operations, the operator can easily remove the trough-shaped plate 8 from the aeroponic cultivation device and then place it on the two support blocks 19. By adjusting the height of the support blocks 19, the trough-shaped plate 8 is erected to a height suitable for operation. This design greatly facilitates the planting or harvesting operation process, reduces the labor intensity of the operator, and improves work efficiency. At the same time, since the trough-shaped plate 8 itself has a trough-shaped structure, when it is buckled on the support block 19, stable clamping can be achieved, effectively preventing the accidental drop of the trough-shaped plate 8 during the planting or harvesting operation, ensuring the safety and reliability of the operation.

[0051] In actual aeroponic cultivation practice, technicians found that the roots of plants cultivated by the aeroponic method are often relatively developed. Although well-developed roots contribute to the absorption of nutrients and water by plants, it brings many inconveniences during harvesting. Usually, the operator needs to pull out the mature plants from the planting trough 9 one by one. This operation method is cumbersome and time-consuming, greatly reducing the harvesting efficiency and becoming one of the bottleneck problems restricting the further popularization and application of aeroponic cultivation technology.

[0052] To address this key technical problem, this embodiment has a further improvement plan. Among the two support blocks 19 on one side of the water storage tank 1, a slot is specifically opened in one of the support blocks 19, and a scraper 20 is installed inside the slot, as shown in the attached Figure 8 figure. During the harvesting operation, the operator can place one end of the trough-shaped plate 8 stably on the support block 19 equipped with the scraper 20, and then slowly and evenly push the trough-shaped plate 8. With the sharp blade of the scraper 20, the roots of the plants can be cut off, thus realizing the rapid separation of the plants from the planting trough 9. This improvement measure significantly improves the harvesting efficiency, avoids the cumbersome root removal operation in the later stage, provides great convenience for the harvesting of plants, and at the same time reduces the risk of damage to the plant roots and cultivation environment, contributing to the long-term stable operation of the aeroponic cultivation system.

[0053] Furthermore, inside the slot of the support block 19, a tool holder 22 for installing the scraper 20 is hinged by a pin shaft 21, as shown in the attached Figure 9 figure. One side of the tool holder 22 close to the pin shaft 21 extends an extension part, which can be in close contact and cooperate with the bottom of the slot of the support block 19. A pin hole is opened on the extension part, and correspondingly, a limit pin 23 is movably inserted at the position corresponding to the pin hole on the support block 19.

[0054] When it is necessary to perform a cutting operation on the plant roots, the operator can turn up the tool rest 22 until the extension of the tool rest 22 is completely fitted to the bottom of the slot of the support block 19, then the scraper 20 can be adjusted to a suitable cutting angle. At this time, insert the limit pin 23 into the pin hole to firmly lock the tool rest 22, ensuring the smooth progress of the cutting operation and the stability of the cutting effect.

[0055] When the cutting operation is not required, the operator can pull out the limit pin 23, so that the tool rest 22 can flexibly rotate around the pin shaft 21, and retract it into the slot of the support block 19 until the scraper 20 is closely fitted to the bottom of the slot of the support block 19. This design effectively avoids accidental injury accidents that may be caused by the scraper 20 in the idle state, significantly improves the safety performance of the entire aeroponic cultivation device, and at the same time extends the service life of the scraper 20 and reduces the equipment maintenance cost.

[0056] In addition, an adjustment slot is provided on the blade plate of the scraper 20. Correspondingly, a locking screw 24 is threadedly connected to the tool rest 22. The operator can flexibly adjust the protruding length of the scraper 20 by loosening the locking screw 24 according to the actual cutting requirements to ensure the best cutting effect on the plant roots.

[0057] At the same time, the operator can also regularly remove the scraper 20 and sharpen its blade. By using professional knife sharpening tools and techniques, the sharpness of the blade of the scraper 20 can be restored, so as to ensure that the scraper 20 can always achieve a good cutting effect on the plant roots during long-term use, maintaining the high efficiency and quality stability of the harvesting operation. In addition, regularly maintaining and servicing the scraper 20 helps to prevent the blade from rusting or becoming dull, further extending the service life of the scraper 20 and reducing the equipment operation cost.

[0058] To further improve the operation convenience and safety, a handle 25 is installed at a position near the bottom of the trough-shaped plate 8. Whether it is for the installation and disassembly operation of the trough-shaped plate 8 or during the root removal operation, the operator can easily lift the handle 25 with one hand and perform auxiliary operations with the other hand, thus more stably controlling the movement and positioning of the trough-shaped plate 8, effectively reducing the operation difficulty and safety risks. At the same time, the assembly relationship between the trough-shaped plate 8 and the support block 19 is fully considered in the design process to ensure that the height settings of the pin shaft 21 and the limit pin 23 on the support block 19 will not interfere with the trough-shaped plate 8, thus ensuring that the root removal operation can proceed smoothly and without obstacles, further improving the overall performance and practicality of the aeroponic cultivation device.
