Detailed implementation manners

[0027] In modern agricultural production, tomatoes, as an important vegetable crop, their yield and quality are directly related to the economic benefits of farmers. In order to improve the yield and quality of tomatoes, many advanced planting techniques have been widely applied, and among them, the tomato grafting seedling raising technique is an important part. Tomato grafting seedling raising can not only improve the stress resistance of plants, but also effectively prevent and control some common diseases, such as Verticillium wilt, Fusarium wilt, etc. However, the traditional tomato grafting seedling raising method has problems such as complex operation and low efficiency. Therefore, it is particularly important to develop an efficient and convenient optimized device for tomato grafting seedling raising. Currently, some optimized devices for tomato grafting seedling raising have emerged on the market. These devices have their own characteristics in terms of structure, but they are all committed to improving the grafting efficiency and seedling raising quality.

[0028] Overall structure of the device: The optimized device for tomato grafting seedling raising mainly consists of two major parts, namely the left box and the right box. The left box and the right box are symmetric in structure and are quickly fixed and disassembled through the connection method of the clamping plate and the clamping groove. This design not only facilitates the assembly and disassembly of the device, but also makes it convenient for operation during transportation and storage. Support feet are provided at the bottom of both the left box and the right box to ensure that the device can maintain stability when placed. A clamping plate is fixedly connected to the lower part of the left side surface of the left box, while a clamping groove matching the clamping plate is provided on the lower part of the left side surface of the right box. When the left box and the right box need to be connected, just insert the clamping plate into the clamping groove to achieve their tight fixation. In addition, grooves are provided on the outer surfaces of both the left box and the right box. These grooves not only increase the stability of the device, but also play a buffering role during transportation, reducing the damage to the seedlings caused by the impact force. A first rubber layer is fixedly connected to the inner wall of the groove, and this rubber layer further enhances the buffering effect of the device. On the upper surfaces of both the left box and the right box, circular grooves are provided. The design of these circular grooves is to cooperate with the cylinder. A piston and a threaded rod are provided inside the cylinder. By adjusting the position of the threaded rod, the movement of the piston inside the cylinder can be controlled, thereby adjusting the gas pressure inside the circular groove. When the device is subjected to an impact force, the first rubber layer will drive the compression spring to move towards the inside of the groove under the action of the pressure, causing the gas inside the groove to flow into the inner wall of the circular groove, and then adjusting the buffering effect of the device and slowing down the damage to the seedlings caused by the impact force.

[0029] Seedling-raising functional structure: In addition to the basic connection and buffer structures, the optimized tomato grafting and seedling-raising device also designs a series of seedling-raising functional structures to improve the efficiency and quality of seedling-raising. Inside the left box and the right box, there are seedling placement platforms. These placement platforms can adjust the height according to needs to adapt to seedlings of different sizes. The surface of the placement platform is also covered with a layer of seedling-raising substrate to provide sufficient nutrition and moisture for the seedlings. To improve the seedling-raising efficiency, the device also designs an irrigation system. The irrigation system includes a water tank, a water pipe, and a nozzle. The water in the water tank is transported to the nozzle through the water pipe and then evenly sprayed on the seedlings by the nozzle. This irrigation method can not only ensure that the seedlings obtain sufficient water but also reduce the waste of water resources.

[0030] Grafting functional structure: As an important part of the optimized tomato grafting and seedling-raising device, the design of the grafting functional structure is crucial. Through a series of delicate designs, the device realizes the efficient grafting of tomato seedlings. There are multiple grafting clamping parts inside the device. These clamping parts are composed of clamping arc plates and push rods. The inner surface of the clamping arc plate is provided with a buffer pad to prevent damage to the seedlings during the clamping process. The push rod is connected to the clamping arc plate by a thread, and the opening and closing degree of the clamping arc plate can be adjusted by rotating the push rod. During the grafting process, the annular elastic band plays a key role. The annular elastic band is sleeved on the outer surface of the insertion joint of the mother plant and the grafting branch. While pulling the outer fixing tube to push the clamping arc plate to be fixed, the clamping rope moves along with the movement of the outer fixing tube, causing the inner wall of the annular elastic band to contract, and then winding and fixing the insertion joint of the mother plant and the grafting branch. This design not only improves the firmness of grafting but also effectively prevents the problem of grafting failure. To enhance the stability and support force of the device, the device also designs a telescopic rod and a fixed column. The telescopic rod is composed of a sleeve rod, a support rod, and a pin and can adjust the length according to needs. The fixed column is fixedly installed on the outer fixing tube and is hinged to the telescopic rod. When the outer fixing tube and the inner fixing tube fix the mother plant and the grafting branch, rotate the telescopic rod on the fixed column, extend the telescopic rod, and insert it into the ground. Then, the outer fixing tube can be supported by the telescopic rod to prevent the mother plant and the grafting branch from being separated due to external forces.

[0031] Working principle of the device: First, connect the left box and the right box through the clamping plate and the clamping groove to ensure the overall stability of the device. Then, adjust the height of the seedling placement table to adapt to seedlings of different sizes. Place the tomato seedlings to be grafted on the seedling placement table, and ensure that the roots of the seedlings are fully extended and in close contact with the seedling-growing substrate. Provide sufficient water for the seedlings through the irrigation system. Open the valve of the water tank, and the water is transported through the water pipe to the nozzle, and then evenly sprayed on the seedlings by the nozzle. When the seedlings grow to a certain stage, start the grafting operation. First, wind and fix the insertion joint of the mother plant and the grafting branch with a circular elastic band. Then, while pushing the clamping arc plate fixed by pulling the outer fixing pipe, the clamping rope moves with the movement of the outer fixing pipe, causing the inner wall of the circular elastic band to contract, further fixing the insertion joint of the mother plant and the grafting branch. Finally, adjust the opening and closing degree of the clamping arc plate by rotating the push rod to fix the grafting branch on the mother plant. After the grafting is completed, post-planting management of the seedlings is required. This includes regular irrigation, fertilization, pest and disease control, etc. Through reasonable post-planting management, the healthy growth of the seedlings can be ensured and the grafting success rate can be improved.

[0032] Advantages and disadvantages of the device: Advantages: High-efficiency grafting: Through a series of delicate designs, the device realizes the high-efficiency grafting of tomato seedlings. The combined use of structures such as grafting clamping parts, circular elastic bands, and clamping ropes greatly improves the firmness and success rate of grafting. Buffer protection: The groove and the first rubber layer designed on the outer surface of the device can play a buffering role during transportation and storage, reducing the damage to the seedlings caused by impact force. Convenient irrigation: The design of the irrigation system makes the irrigation process more convenient and fast, and can ensure that the seedlings obtain sufficient water. Easy to operate: The assembly and disassembly process of the device is relatively simple and easy to operate and use. Disadvantages: High cost: Due to the use of a variety of precise structural designs in the device, its manufacturing cost is relatively high. This limits its wide application in agricultural production to a certain extent. Complicated maintenance: Due to the relatively complex structure of the device, the maintenance is also more cumbersome. It is necessary to regularly check and repair each component to ensure its normal operation. Limited scope of application: This device is mainly applicable to tomato grafting and seedling raising, and may not be applicable to the grafting and seedling raising of other crops. This limits its versatility in agricultural production.

[0033] Although there are some shortcomings in the tomato grafting seedling optimization device, its advantages in practical application are still very obvious. With the continuous advancement of agricultural production technology and the increasing demand of farmers for efficient planting technology, the application prospects of this device are very broad. In order to promote the widespread application of this device, the following measures can be taken: Reduce manufacturing costs: By optimizing the design and production process, the manufacturing cost of the device can be reduced to make it more economical. Strengthen technical training: Provide technical training to farmers to improve their operating skills and maintenance capabilities to ensure that the device can operate normally and function. Expand the scope of application: Carry out relevant research and technical improvements to meet the needs of grafting seedlings of other crops and expand the scope of application of the device. In future development, the following technical innovation directions can be further explored: Intelligent control: Apply advanced technologies such as the Internet of Things and artificial intelligence to the device to achieve intelligent control and remote monitoring, and improve the automation level and production efficiency of the device. Multifunctional integration: Integrate multiple functions into the device, such as pest control, nutrient supply, etc., to improve the comprehensive performance and practicality of the device. Environmental protection and energy saving: Use environmentally friendly materials and energy-saving technologies to reduce the energy consumption and environmental pollution of the device and promote sustainable agricultural development.

[0034] The tomato grafting seedling optimization device has a sophisticated structural design and comprehensive functions, which can significantly improve the efficiency and success rate of tomato grafting seedlings. Although there are some shortcomings, with the continuous advancement of technology and the promotion of application, it is believed that the device will play an increasingly important role in agricultural production. In the future, we will continue to explore and optimize related technologies to provide more efficient and convenient solutions for agricultural production. In practical applications, farmers should choose appropriate devices according to their own needs and actual conditions, and operate and maintain them in strict accordance with the operating procedures to ensure the normal operation of the device and achieve the best results. At the same time, the government and relevant departments should also strengthen the research and development and promotion support for such devices to promote the continuous advancement of agricultural production technology and the continuous improvement of farmers' economic benefits.

[0035] After analyzing the structure and advantages and disadvantages of a typical tomato grafting seedling optimization device on the current market, we can further propose optimization ideas and explore how to combine existing technologies with these optimization ideas to create a more efficient, intelligent and environmentally friendly tomato grafting seedling device.

[0036] Optimization Ideas: To reduce manufacturing costs and improve the versatility of the device, modular design can be considered. Design each functional part of the device (such as the irrigation system, grafting clamp, seedling placement table, etc.) into independent modules, and users can select and combine these modules according to actual needs. This can not only meet the personalized needs of different users but also facilitate maintenance and upgrading. Introduce Internet of Things, sensor, and artificial intelligence technologies to achieve intelligent control of the device. For example, by installing temperature sensors, humidity sensors, and light sensors, the seedling-growing environment can be monitored in real time, and parameters such as irrigation volume, light intensity, and temperature can be automatically adjusted according to the monitoring results to create the most suitable seedling-growing conditions. At the same time, use artificial intelligence technology to intelligently identify and control the grafting process to improve the accuracy and efficiency of grafting. Incorporate energy conservation and environmental protection concepts into the design of the device, use energy-saving materials and low-energy-consuming technologies to reduce the energy consumption of the device. For example, use LED light sources to replace traditional light sources for light supplementation, which is both energy-saving and environmentally friendly. In addition, the use of renewable energy such as solar energy to power the device can be considered to further reduce energy consumption. Through the remote monitoring and management system, users can understand the operating status and seedling-growing situation of the device at any time and anywhere and perform remote operations and management. This can not only improve management efficiency but also promptly discover and solve problems to ensure the smooth progress of the seedling-growing process.

[0037] Integration with Existing Technologies: Internet of Things technology can connect various modules in the device to form an intelligent seedling-growing ecosystem. Through Internet of Things technology, users can monitor and control the seedling-growing environment in real time, such as temperature, humidity, light, etc., and automatically adjust relevant parameters according to the monitoring results. In addition, Internet of Things technology can also achieve remote monitoring and management functions, facilitating users to understand the operating status and seedling-growing situation of the device at any time. 3D printing technology can be used to manufacture various modules and components of the device to achieve rapid customization and personalized production. Through 3D printing technology, users can design and manufacture seedling-growing device modules suitable for themselves according to actual needs, reducing manufacturing costs and improving the versatility of the device. At the same time, 3D printing technology can also be used to manufacture complex grafting clamps and annular elastic bands and other components to improve the accuracy and efficiency of grafting. Artificial intelligence and machine learning technologies can be used to intelligently identify and control the grafting process. By training machine learning models, automatic identification and classification of the grafting process can be achieved, improving the accuracy and efficiency of grafting. At the same time, artificial intelligence can also be used to optimize the seedling-growing environment parameters, automatically adjusting parameters such as irrigation volume, light intensity, and temperature according to real-time monitoring data to create the most suitable seedling-growing conditions. Incorporate energy conservation and environmental protection technologies into the design of the device, such as using energy-saving materials and low-energy-consuming technologies to reduce the energy consumption of the device. At the same time, the use of renewable energy to power the device, such as solar energy, wind energy, etc., can be considered. In addition, intelligent energy-saving algorithms can be used to manage the energy consumption of the device, automatically adjusting the energy consumption level according to actual needs to achieve the goal of energy conservation and environmental protection.

[0038] Implementation steps and expected effects: Research and analysis: Conduct research and analysis on existing tomato grafting and seedling-raising devices in the market to understand their advantages, disadvantages, and user needs. Design and optimization: Based on the research results and user needs, put forward optimization ideas in aspects such as modular design, intelligent control, energy conservation and environmental protection, and remote monitoring and management, and draw detailed design drawings.

Demonstration and promotion: Conduct demonstration applications at suitable locations to showcase the advantages and effects of the device, and gradually promote it to a wider user group. Improve grafting efficiency and success rate: Through intelligent control and modular design, improve the accuracy and efficiency of grafting and reduce the grafting failure rate. Reduce manufacturing costs and maintenance costs: Adopt modular design and 3D printing technology to reduce the manufacturing cost of the device; through intelligent control and remote monitoring and management functions, reduce the maintenance cost. Create a suitable seedling-raising environment: By real-time monitoring and controlling the seedling-raising environment parameters, create the most suitable seedling-raising conditions and improve the growth rate and quality of the seedlings. Promote the sustainable development of agriculture: Through the use of energy conservation and environmental protection technologies and renewable energy, reduce the energy consumption and environmental pollution of the device and promote the sustainable development of agriculture.

[0039] Through the analysis of a typical tomato grafting and seedling-raising optimization device in the current market and the proposal of optimization ideas, we can combine existing technologies such as the Internet of Things, 3D printing, artificial intelligence, and energy conservation and environmental protection to create a more efficient, intelligent, and environmentally friendly tomato grafting and seedling-raising device. This will help improve grafting efficiency and success rate, reduce manufacturing costs and maintenance costs, create a suitable seedling-raising environment, and promote the sustainable development of agriculture. In the future, we will continue to pay attention to the development trends of related technologies and continuously explore and optimize related technologies to provide more efficient and convenient solutions for agricultural production.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] Refer to Figures 1-8As shown in the figure, this embodiment provides an optimized device for tomato grafting and seedling raising, including an arch shed 7. Heat preservation boards 5 are respectively installed on both sides of the arch shed 7. Ventilation openings are formed in the heat preservation boards 5. Baffles 6 are symmetrically and slidably connected at the ventilation openings. Frameworks 1 are symmetrically installed outside the arch shed 7. Three slide rails 4 are fixedly connected between the two frameworks 1. A sunshade net 2 is laid outside the slide rails 4. The sunshade net 2 is adapted to the length of the slide rails 4. A driving component is installed on the middle slide rail 4. The driving component is in transmission connection with the sunshade net 2. A support 8 is installed inside the arch shed 7. A number of seedling raising pots 9 are placed on the support 8. A number of tomato grafted seedlings are planted in the seedling raising pots 9. A number of protection components for protecting the grafting parts of the grafted seedlings are installed in the seedling raising pots 9.

[0043] Place the grafted tomato seedlings in the seedling raising pots 9, and place the seedling raising pots 9 on the support 8 inside the arch shed 7; by adjusting the position of the baffle 6, the size of the ventilation opening can be controlled, and then selective ventilation can be carried out according to the temperature and humidity inside the shed; in order to avoid direct sunlight, drive the sunshade net 2 to move through the driving component, so that the sunshade net 2 completely covers the arch shed 7, thereby playing a sunshading role. When not in use, drive the sunshade net 2 to move in the reverse direction and retract the sunshade net 2, which is time-saving and labor-saving and does not require manual covering. The present invention controls the laying of the sunshade net 2 through the driving component, and can stop at any time, maximizing the realization of selective covering, with strong adjustability, time-saving and labor-saving, and the size of the ventilation opening can be adjusted at will to avoid sudden drop in the temperature inside the shed; multiple grafted seedlings can be placed in the seedling raising pot 9, which is convenient for later transplantation.

[0044] For a further optimized solution, the driving component includes a slider 3 slidably connected to the slide rail 4. The slider 3 is in transmission connection with the sunshade net 2. A motor 16 is fixedly connected to the side wall of the slider 3. A first transmission wheel 17 is fixedly connected to the output shaft of the motor 16. The first transmission wheel 17 is in transmission connection with a second transmission wheel 19 through a belt 18. A connecting shaft 20 is fixedly connected to the second transmission wheel 19. The connecting shaft 20 extends into the slider 3 and is rotatably connected to the slider 3. An opening is provided at the bottom of the slider 3. A first gear 21 is installed in the opening. The first gear 21 is fixedly connected to the connecting shaft 20. A tooth groove 22 is formed at the bottom of the slide rail 4. The first gear 21 meshes with the tooth groove 22. The motor 16 drives the first transmission wheel 17 to rotate. The first transmission wheel 17 drives the second transmission wheel 19 to rotate through the belt 18. The second transmission wheel 19 drives the connecting shaft 20 to rotate. The connecting shaft 20 drives the first gear 21 to rotate. The first gear 21 meshes with the tooth groove 22, so that the first gear 21 moves along the slide rail 4, and then the slider 3 moves along the slide rail 4, and then drives the sunshade net 2 to move to complete the sunshading work.

[0045] For a further optimized solution, a circular ring 29 is sleeved on the sliding rail 4. The circular ring 29 is fixedly connected to the sunshade net 2. The circular ring 29 in the middle is fixedly connected to the slider 3. Connecting rods 30 are fixedly connected between adjacent circular rings 29. The slider 3 drives the circular ring 29 to move, and the circular ring 29 drives the sunshade net 2 to move, thus completing the sunshading work. The arrangement of the connecting rods 30 ensures the synchronization of the movement of the sunshade net 2, making it more convenient to use.

[0046] For a further optimized solution, teeth are provided on the bottom surface of any baffle 6. The teeth are engaged with a second gear 23. A central shaft 24 is rotatably connected to the center of the second gear 23. The central shaft 24 is fixedly connected in the heat preservation plate 5. A chute 28 is formed in the heat preservation plate 5. A toothed plate 25 is slidably connected in the chute 28. The top surface of the toothed plate 25 is engaged with the second gear 23. A pair of vertical rods 26 are fixedly connected to the side of the toothed plate 25 away from the second gear 23. The vertical rods 26 are fixedly connected to another baffle 6. When adjusting the size of the ventilation opening, pull the baffle 6. When the baffle 6 moves, it drives the second gear 23 to rotate. The second gear 23 drives the toothed plate 25 to move in the chute 28. The toothed plate 25 drives the vertical rods 26 to move. The vertical rods 26 drive another baffle 6 to move, so that the two baffles 6 move in opposite directions to open the ventilation opening. When closing, move in the reverse direction, and the operation is simple and convenient.

[0047] For a further optimized solution, a groove 27 is formed in the heat preservation plate 5. The groove 27 communicates with the chute 28. The vertical rod 26 is located in the groove 27 and is slidably connected to the groove 27. The arrangement of the groove 27 facilitates the sliding of the vertical rod 26.

[0048] For a further optimized solution, a number of partitions 10 are fixedly connected in the seedling raising pot 9. The number of partitions 10 divides the seedling raising pot 9 into a number of seedling raising cavities. Grafted seedlings are planted in the seedling raising cavities. The protection components are installed on the partitions 10 and the seedling raising pot 9. Through the arrangement of the partitions 10, multiple grafted seedlings can be cultivated in the seedling raising pot 9, and the partitions 10 can also prevent the spread of root diseases and reduce losses.

[0049] For a further optimized solution, the protection component includes a sleeve 13 rotatably connected to the partition 10. A sliding rod 12 is slidably connected in the sleeve 13. A universal joint is installed at the top of the sliding rod 12. A protection plate 14 is installed on the universal joint. The protection plate 14 contacts the grafted seedling. After grafting, rotate the sleeve 13 and extend the sliding rod 12 to make the protection plate 14 located above the grafting position. Since the humidity in the shed is relatively high, the protection plate 14 can prevent the water droplets on the shed roof from dripping on the grafting position, thereby preventing the infection of the grafting interface and causing leaf lesions, and preventing the influence on the healing of the grafting interface.

[0050] For a further optimized solution, a notch 15 is formed in the protection plate 14. The main stem of the grafted seedling is located in the notch 15. The main stem is stuck in the notch 15, so as to effectively prevent water droplets from dripping on the grafting interface.

[0051] For a further optimized solution, handles 11 are symmetrically and fixedly connected to both sides of the seedling-raising pot 9. The provision of the handles 11 facilitates lifting the seedling-raising pot 9, which is convenient for transportation and transplanting.

[0052] For a further optimized solution, humidity sensors are respectively arranged in several seedling cavities. A water pipe is installed on the bracket 8, and several drip irrigation heads are connected to the water pipe and extend into the seedling cavities. In the initial stage after grafting, since the root systems of the grafted seedlings have not fully recovered, it is necessary to control the amount of watering to avoid excessive water causing root rot.

[0053] When the grafted seedlings enter the normal growth period, the soil humidity is measured by the humidity sensors. Watering is carried out when the soil surface is slightly dry to keep the soil moist but not waterlogged. The drip irrigation method can supply water more evenly, reducing the risk of water waste and disease transmission. Also, watering should be avoided during the high-temperature period at noon to prevent the grafted seedlings from losing water due to rapid water evaporation. After watering, open the ventilation openings and ventilate in time to remove moisture, reducing the humidity in the shed and the occurrence of diseases.
