Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural technology, specifically to an intelligent agricultural greenhouse for modern agriculture. Background Technology

[0002] With the development of smart agriculture, smart greenhouses have been widely used as an efficient and precise agricultural production model. However, in terms of pest and disease control, existing smart greenhouse systems still face significant challenges: the difficulty in accurately locating pests and diseases.

[0003] Current methods for controlling pests and diseases in greenhouses still rely heavily on extensive pesticide spraying. This not only results in significant pesticide waste but also has negative impacts on the environment and agro-ecosystems. Firstly, large amounts of pesticides are sprayed in areas with few or no pests and diseases, wasting valuable resources and causing unnecessary environmental pollution. The widespread use of pesticides also poses a deadly threat to beneficial organisms within the greenhouse, weakening the ecosystem's natural control mechanisms and ironically promoting the rapid proliferation of pests, making the greenhouse's internal ecosystem even more fragile.

[0004] In the long-term process of pest and disease control, indiscriminate use of pesticides can also lead to soil compaction and groundwater pollution. These phenomena not only reduce soil productivity and environmental carrying capacity, but also directly affect the safety and quality of agricultural products. Summary of the Invention

Detailed Implementation

[0020] 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.

[0021] Example 1: like Figures 1-3 As shown in the figure, an embodiment of the present invention discloses a modern intelligent agricultural greenhouse, including a greenhouse frame 1, with a greenhouse cloth 2 fixedly connected to the outside of the greenhouse frame 1. An intelligent inspection mechanism 3 is installed inside the greenhouse frame 1. The intelligent inspection mechanism 3 performs patrol-style inspections of the greenhouse, and by collecting information on the crops inside the intelligent agricultural greenhouse, it can analyze the growth status of the crops. When abnormalities occur in the growth status of the crops, it can report them or handle them automatically.

[0022] like Figures 1-3 As shown, the intelligent inspection mechanism 3 includes a pair of slide rails 4, on which electric sliders 5 are slidably connected. A first horizontal plate 6 is fixedly connected between the pair of electric sliders 5. The electric sliders 5, carrying the first horizontal plate 6, slide in the opposite direction along the slide rails 4. The slide rails 4 are generally arranged in a closed loop within the greenhouse frame 1, meaning the electric sliders 5 can move continuously on the slide rails 4. The path of the slide rails 4 needs to be specifically designed according to the specific specifications of the intelligent agricultural greenhouse; it can be of any shape, ensuring that the electric sliders 5 cover all crops inside the intelligent agricultural greenhouse during their sliding motion on the slide rails 4.

[0023] like Figures 1-3As shown, a carrier 9 is fixedly connected to the lower end of the first horizontal plate 6. A vision detection mechanism 10 is fixedly connected to the carrier 9. A targeted spraying mechanism 11, matching the vision detection mechanism 10, is also installed on the carrier 9. The vision detection mechanism 10 is used to collect images of crops inside the greenhouse. The targeted spraying mechanism 11 performs precise pesticide application on the crops based on the crop information collected by the vision detection mechanism 10. The smart agricultural greenhouse also includes a control unit. The control unit is communicatively connected to the vision detection mechanism 10 and the targeted spraying mechanism 11. Under normal circumstances, the control unit analyzes the crop images collected by the vision detection mechanism 10 to obtain a detection signal. In response to the detection signal, the electric slider 5 and the targeted spraying mechanism 11 are activated by the control unit to move the electric slider 5 and the first horizontal plate 6 to the corresponding area and to start the targeted spraying mechanism 11 to perform pesticide application.

[0024] Preferably, the visual inspection unit 10 typically consists of a high-definition camera and a multispectral imager, capable of continuously acquiring image data of key parts of crops such as leaves and stems within the greenhouse. Multispectral imaging can reveal early symptoms of pests and diseases that are difficult to detect with the naked eye.

[0025] Preferably, the control unit preprocesses the acquired raw images, including noise reduction, enhancement, and cropping, to improve the accuracy of subsequent analysis. The control unit integrates a crop disease and pest image recognition algorithm model, such as a Convolutional Neural Network (CNN) based on deep learning. The model compares the real-time acquired images with a pre-established disease and pest database to identify the types of diseases and pests and assess their severity. The targeted spraying mechanism 11 then precisely sprays pesticides onto the crops based on the severity level assessed by the control unit.

[0026] like Figure 9 As shown, the targeted spray mechanism 11 includes a first motor 13, which is fixed to the lower end of the carrier 9 as a base motor. A first connector 12 is fixedly connected to the output shaft of the first motor 13. A second motor 15 is fixedly connected to the first connector 12. A second connector 14 is fixedly connected to the output shaft of the second motor 15. A third motor 17 is fixedly connected to the second connector 14. A nozzle 16 is fixedly connected to the output shaft of the third motor 17. A nozzle 1601 is fixedly connected to the nozzle 16.

[0027] Specifically, the output shaft of the first motor 13 drives the entire targeted spraying mechanism 11 to achieve basic rotation in the horizontal plane, thereby adjusting the basic orientation of the nozzle 16. The output shaft of the second motor 15 drives the second connecting member 14 to rotate in a direction perpendicular to the first connecting member 12, that is, to achieve left-right rotation, which can tilt the spray angle of the nozzle 16. The third motor 17 rotates the nozzle 16 to adjust the pitch angle. Through the multi-angle adjustment of the targeted spraying mechanism 11, the final spray direction is determined, ensuring that the pesticide accurately covers the infected parts of the target leaves or stems, achieving efficient targeted application.

[0028] like Figures 1-6 As shown, the carrier 9 has a storage tank 19 inside, which stores pesticides for crops. A delivery pipe 18 is fixedly connected between the nozzle 16 and the storage tank 19. A micro pump that matches the delivery pipe 18 is fixedly connected inside the carrier 9. That is, the micro pump delivers the pesticide in the storage tank 19 to the nozzle 16, and finally the pesticide is sprayed out by the nozzle 1601.

[0029] In the above embodiments, the intelligent agricultural greenhouse of modern agriculture uses a built-in slide rail 4. A closed-loop slide rail 4 is set according to the specific conditions of the greenhouse, allowing the electric slider 5 to slide along the direction of the slide rail 4, and moving the carrier 9 so that the carrier 9 completely covers the crops inside the intelligent agricultural greenhouse. The electric slider 5 operates continuously, moving the vision detection mechanism 10 on the carrier 9 to collect information about the crops. The control unit analyzes the crop images collected by the vision detection mechanism 10, and the targeted spraying mechanism 11 adjusts according to the analysis results to achieve precise spraying of the diseased areas of the crops.

[0030] Example 2: In practical use, it was found that multiple defects may be detected simultaneously. If only one liquid storage tank 19 is installed inside the carrier 9, it is difficult to handle multiple defect conditions. To solve the above problem, this embodiment adopts the following solution: like Figures 1-6As shown, a liquid inlet pipe 20 is fixedly connected to the carrier 9, and the liquid inlet pipe 20 is connected to the storage tank 19. A diversion plate 21 is fixedly connected to the liquid inlet pipe 20, and the diversion plate 21 is located on the inner top wall of the storage tank 19. The bottom of the storage tank 19 is a conical bottom 1901. A liquid outlet pipe 23 matching the storage tank 19 is fixedly connected to the carrier 9, and a connecting pipe 24 is installed between the liquid outlet pipe 23 and the bottom wall of the conical bottom 1901. A liquid replenishment mechanism 29 is also fixedly connected to the greenhouse frame 1. The liquid replenishment mechanism 29 can communicate with the liquid inlet pipe 20. When the liquid replenishment mechanism 29 and the liquid inlet pipe 20 are connected, pesticides can be added to the storage tank 19 through the liquid inlet pipe 20. When the liquid replenishment mechanism 29 is connected to the liquid inlet pipe 20, it is also connected to the liquid outlet pipe 23. The liquid replenishment mechanism 29 can remove residual pesticides before adding pesticides to the liquid inlet pipe 20.

[0031] Specifically, such as Figures 1-6 As shown, the liquid replenishment mechanism 29 includes a second horizontal plate 30, which is fixedly connected to the greenhouse frame 1 and located at the upper end of the slide rail 4. The position of the second horizontal plate 30 does not affect the sliding of the electric slider 5 on the slide rail 4. An electric push rod 31 is fixedly connected to the upper part of the second horizontal plate 30. The protruding end of the electric push rod 31 passes through the second horizontal plate 30 and is fixedly connected to a connecting plate 34. A liquid extraction pipe 32 and a liquid delivery pipe 33 are fixedly connected to the connecting plate 34. The positions of the liquid extraction pipe 32 and the liquid delivery pipe 33 match the positions of the liquid outlet pipe 23 and the liquid addition pipe 20. A second through hole 602 matching the liquid extraction pipe 32 and the liquid delivery pipe 33 is provided on the first horizontal plate 6. After passing through the second through hole 602, the liquid extraction pipe 32 and the liquid delivery pipe 33 are inserted into the liquid addition pipe 20 and the liquid outlet pipe 23.

[0032] like Figures 1-6 As shown, a first infusion pipe 3201 is fixedly connected to the extraction pipe 32, and a second infusion pipe 3301 is fixedly connected to the delivery pipe 33. The first infusion pipe 3201 is connected to the pesticide recovery mechanism, and the second infusion pipe 3301 is connected to the pesticide dispensing mechanism. The pesticide recovery mechanism extracts the pesticide residue in the carrier 9 and can transport the extracted residue to the corresponding storage tank in the pesticide dispensing mechanism. The pesticide dispensing mechanism generally has multiple storage tanks, which store pesticides for treating different pests. The pesticide dispensing mechanism can deliver the corresponding pesticide to the storage tank 19 according to the needs of the control unit.

[0033] In the above embodiments, the entire process from pesticide replenishment and pipeline connection to residual liquid cleaning is fully automated, which can significantly reduce the intensity and cost of manual operation. By using the logic of first draining and then adding, it ensures that each application is a pesticide solution with a preset concentration and type, avoiding the risk of reduced efficacy or phytotoxicity caused by residual liquid contamination, ensuring the control effect and crop safety, minimizing the need for personnel to directly contact and operate pesticides, reducing the risk of poisoning, and improving the safety of agricultural production.

[0034] In addition, the liquid replenishment mechanism 29 is fixed above the greenhouse frame 1, without occupying planting space or affecting the normal movement and inspection path of the intelligent inspection mechanism 3. The conical bottom 1901 and the pipe plug-in design are simple and reliable, ensuring the accuracy of residual liquid drainage and pipe connection.

[0035] Example 3: The pesticide replacement method in Example 2 inevitably leads to pesticide mixing, which may ultimately affect the pesticide's effectiveness in treating pests. To solve the above problem, this example adopts the following solution: like Figures 1 to 7 As shown, the distribution plate 21 is equipped with multiple distribution holes. The distribution holes near the side wall of the storage tank 19 are inclined (not shown in the figure). Before the pesticide is introduced through the distribution plate 21, the pesticide dispensing mechanism first delivers clean water into the storage tank 19 through the delivery pipe 33. The clean water is used to rinse the inner wall of the storage tank 19. The inclined distribution holes can spray the pesticide onto the inner wall of the storage tank 19, and the impact force separates the pesticide from the inner wall of the storage tank 19. The rinsed water is still discharged through the extraction pipe 32.

[0036] After the inner wall of the storage tank 19 has been rinsed, the corresponding pesticide is then delivered into the storage tank 19 through the pesticide dispensing mechanism. Furthermore, a hydrophobic coating can be provided on the inner wall of the liquid storage tank 19. Water rinsing and the hydrophobic coating work together to improve the rinsing effect on the inner wall of the liquid storage tank 19.

[0037] like Figures 6-7 As shown, a hollow connecting rod 22 is fixedly connected to the lower end of the diverter plate 21. A third through hole 2201 is provided on the hollow connecting rod 22, aligned with the side wall of the storage tank 19. A fourth through hole 2202 is provided at the lower end of the hollow connecting rod 22, aligned with the bottom wall of the storage tank 19. In this way, the third through hole 2201 and the fourth through hole 2202 can further enhance the impact effect inside the storage tank 19 without affecting the entry of pesticides into the storage tank 19.

[0038] The solution in this embodiment effectively avoids unnecessary mixing of different pesticides within the storage tank 19. An automated water rinsing process maximizes the removal of any residual pesticides from the previous pesticide, ensuring that any newly added pesticides retain their original composition and concentration, thus guaranteeing that their effectiveness against specific pests and diseases is not compromised by residue.

[0039] Example 4: To further improve the accuracy of the targeted spray mechanism 11, such as Figures 1-4 As shown, a height control mechanism 25 is installed on the first horizontal plate 6. The height control mechanism 25 can raise or lower the height of the carrier 9, so that the targeted spraying mechanism 11 is closer to the crop, reducing the dispersion of pesticides during spraying and reducing the risk of pesticides splashing onto crops that are not diseased.

[0040] Specifically, such as Figures 1-4 As shown, the height control mechanism 25 includes a winder 26 located at the lower end of the first horizontal plate 6. A steel wire rope 27 is wound on the winder 26, passing upward through the first horizontal plate 6 and extending towards the center of the carrier 9. The first horizontal plate 6 has a first through hole 601 that matches the center of the carrier 9. The steel wire rope 27 passes through the first through hole 601, passes through the first horizontal plate 6, and is fixedly connected to the carrier 9. In this way, the carrier 9 can be moved up and down during the operation of the winder 26.

[0041] like Figures 1-4 As shown, the upper end of the carrier 9 is fixedly connected to a guide tube 28 that matches the wire rope 27. It mainly serves as a guide and can also reduce the wear of the wire rope 27.

[0042] To further improve the stability of the load-bearing device 9 during the vertical movement, such as Figures 1-4 As shown, multiple first telescopic components 7 are fixedly connected between the carrier 9 and the first horizontal plate 6. Simultaneously, a second telescopic component 8, matching the steel wire rope 27, is fixedly connected between the carrier 9 and the first horizontal plate 6. The steel wire rope 27 passes through the second telescopic component 8 and is then fixedly connected to the liquid replenishment mechanism 29. Both the first telescopic components 7 and the second telescopic component 8 are made of metal and can limit the forward, backward, left, and right swaying of the carrier 9.

[0043] In this embodiment, the length of the wire rope 27 is controlled by the winder 26, allowing the carrier 9 and its nozzle 16 to be adjusted to the most suitable height at any time. This ensures that the nozzle 16 is as close as possible to the crop canopy or diseased areas. This significantly shortens the pesticide spraying distance, effectively reducing pesticide drift and droplet dispersion caused by factors such as wind and air resistance, ensuring that the pesticide covers the target plants to the maximum extent, and directly improving the control effect.

[0044] The height control mechanism 25 gives the intelligent inspection mechanism 3 versatility. It can dynamically adjust the working height of the carrier 9 according to the canopy height of different crops such as tomatoes, cucumbers, and leafy vegetables, or the growth status of crops from the seedling stage to the fruiting stage, so as to achieve individualized instruction and adapt to diverse planting needs.

[0045] Obviously, the above-described embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
