Description

Technical Field

[0001] This utility model relates to a seedling selection and cultivation device, specifically a smart agricultural greenhouse irrigation device, belonging to the field of agricultural planting technology. Background Technology

[0002] With the rapid development of people's lives, dragon fruit is being consumed more and more frequently. When planting dragon fruit trees, a water spraying device is needed to irrigate them, ensuring that the dragon fruit trees always have a sufficient water supply, preventing the dragon fruit trees from drying out, and making the dragon fruit trees produce fuller and larger fruits.

[0003] Dragon fruit plants have a unique shape. Their growth depends not only on the roots absorbing water and nutrients from the soil, but also on the healthy development of the fruit branches, which plays a crucial role in the yield and quality of the fruit. Traditional agricultural greenhouse irrigation devices can irrigate the roots in the context of dragon fruit cultivation, but they have obvious shortcomings in irrigating the fruit branches.

[0004] In the prior art, such as the dragon fruit root irrigation device disclosed in announcement number CN208850360U, the root system of the dragon fruit tree can be guided to grow downward while irrigating, so that the dragon fruit tree can absorb water from deeper soil layers. This can save irrigation water and increase the disaster resistance of the dragon fruit tree. However, the above-mentioned prior art has the following shortcomings: When the above-mentioned irrigation device is used, its irrigation range is mainly concentrated in the soil area around the roots of the plant. Water droplets or water mist are difficult to effectively cover the upward-growing and widely distributed fruit branches of the dragon fruit. During the vigorous growth period and the fruit enlargement period, the fruit branches of the dragon fruit have specific water requirements. If the fruit branches are in a state of water shortage for a long time, it will lead to the branches withering and slow growth, which will seriously affect flower bud differentiation and fruit formation, thereby reducing the yield and quality of dragon fruit. Summary of the Invention

[0005] The purpose of this invention is to provide a smart agricultural greenhouse irrigation device to solve the problem that the above-mentioned devices cannot effectively deliver water to the upward-growing and widely distributed fruit branches. During the vigorous growth period of the fruit branches and the fruit enlargement period, insufficient water supply will cause the branches to wither and grow slowly, which will seriously hinder flower bud differentiation and fruit formation, and ultimately lead to a decrease in dragon fruit yield and a deterioration in quality.

[0006] This utility model achieves the above objectives through the following technical solution: a smart agricultural greenhouse irrigation device, including an I-beam frame;

[0007] The surface of the I-beam frame is symmetrically equipped with fixed carriages. The two fixed carriages are slidably connected to the same C-shaped hollow frame. The surface of the C-shaped hollow frame is connected to multiple telescopic nozzles, all of which are vertically arranged. A fixed rod is installed at one end of the interior of the fixed carriage. One end of the fixed rod extends into the C-shaped hollow frame and is connected to a piston plate slidably connected inside the C-shaped hollow frame. A pipe joint is connected to one side of the C-shaped hollow frame and is connected to an external pressure pump.

[0008] As a further embodiment of this utility model: a connecting ear is slidably connected in the groove opened on the surface of the fixed slide, the connecting ear is connected to the C-shaped hollow frame, a fixed ear is fixedly installed on one end surface of the fixed slide, a tension spring is installed on the surface of the fixed ear, and one end of the tension spring is connected to the connecting ear.

[0009] As a further embodiment of this utility model: the same adjusting plate is installed on the outer side of multiple telescopic nozzles, a slider is integrally formed on one side of the adjusting plate, an inclined plate is fixedly installed on the surface of the fixed slide, and a groove adapted to the slider is opened on the surface of the inclined plate. The adjusting plate is slidably connected to the surface of the inclined plate through the slider and the groove.

[0010] As a further improvement of this utility model: a nozzle is installed at the outlet of each of the multiple telescopic nozzles, and the nozzle is arranged in a duckbill shape.

[0011] As a further embodiment of this utility model: a rotating shaft is rotatably connected inside the I-beam frame, and a water-guiding adhesive tape is wrapped around the surface of the rotating shaft. Multiple hooks are installed at equal intervals on one side surface of the C-shaped hollow frame, and one end of the water-guiding adhesive tape is hung on the multiple hooks.

[0012] As a further improvement of this utility model: a coil spring is installed on the surface of the rotating shaft, and the other end of the coil spring is connected to the I-beam frame.

[0013] As a further embodiment of this utility model: a rubber scraper is provided at one end of the I-beam frame, and a T-shaped rod is slidably connected in the through hole opened on the surface of the rubber scraper. One end of the T-shaped rod is fixedly installed at the end of the I-beam frame, and a spring is sleeved on the surface of the T-shaped rod. One end of the spring abuts against the T-shaped structure of the T-shaped rod, and the other end of the spring abuts against the rubber scraper.

[0014] As a further improvement of this utility model: the I-beam frame is integrally formed with multiple ground nails, and the ends of the multiple ground nails are all set with a conical structure.

[0015] The beneficial effects of this utility model are:

[0016] This invention utilizes a combination of components including an I-frame, a fixed slide, a C-shaped hollow frame, telescopic nozzles, a fixed rod, a tension spring, an inclined plate, pipe joints, a coil spring, water-guiding tape, and rubber scrapers. The C-shaped hollow frame slides within the fixed slide, allowing multiple vertically positioned telescopic nozzles to move flexibly. This design enables precise adjustment of the irrigation position based on the distribution of dragon fruit plants, comprehensively covering different areas of fruit branches and roots, greatly enhancing the equipment's applicability. Compared to traditional fixed-position irrigation equipment, it better meets the diverse needs of dragon fruit cultivation. Furthermore, the coordinated operation of the adjusting plate, inclined plate, slider, and chute allows the telescopic nozzles to move upwards while moving horizontally towards the plant, precisely targeting the lower ends of fruit branches to ensure sufficient irrigation for these critical areas. This effectively prevents the fruit branches from drying out and stagnating due to lack of water, significantly improving the overall quality and yield of the fruit.

[0017] The duckbill-shaped nozzles installed at the outlets of multiple telescopic spray pipes have a unique flat shape that allows the water to be distributed in a fan shape. Compared with traditional round nozzles, this significantly expands the coverage area of ​​a single irrigation. In dragon fruit greenhouses, this allows for more comprehensive coverage of fruit branches within a limited range of movement, reducing irrigation blind spots and ensuring that all parts of the plant receive sufficient water. In addition, the I-frame is wrapped with water-guiding tape, one end of which is hung on a hook on the side of the C-shaped hollow frame. This allows irrigation water to be diverted to the soil area around the roots of the plant, further expanding the overall irrigation coverage area and ensuring that each dragon fruit plant receives sufficient and appropriate water supply, promoting overall plant growth.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Example 1

[0028] like Figures 1 to 7 As shown, a smart agricultural greenhouse irrigation device includes an I-beam frame 1;

[0029] Fixed slides 3 are symmetrically installed on the surface of the I-frame 1. The two fixed slides 3 are slidably connected to the same C-shaped hollow frame 4. Multiple telescopic nozzles 5 are connected to the surface of the C-shaped hollow frame 4. The multiple telescopic nozzles 5 are all vertically arranged. A fixed rod 7 is installed at one end of the interior of the fixed slide 3. One end of the fixed rod 7 extends into the C-shaped hollow frame 4 and is connected to the piston plate 6 slidably connected in the C-shaped hollow frame 4. A pipe joint 15 is connected to one side of the C-shaped hollow frame 4 and is connected to an external pressure pump.

[0030] The C-shaped hollow frame 4 can slide within the fixed slide 3, driving the telescopic nozzle 5 to move. It can flexibly adjust the irrigation position according to the distribution of dragon fruit plants, accurately covering different areas. Compared with fixed-position irrigation equipment, it is more versatile. When the external pressure pump provides liquids of different pressures, the piston plate 6 will move accordingly, thereby changing the size of the space and the liquid pressure inside the C-shaped hollow frame 4, indirectly controlling the water output and spraying intensity of the telescopic nozzle 5, and achieving precise control of irrigation intensity.

[0031] Furthermore, a connecting ear 8 is slidably connected in the groove opened on the surface of the fixed slide 3. The connecting ear 8 is connected to the C-shaped hollow frame 4. A fixed ear 10 is fixedly installed on one end of the fixed slide 3. A tension spring 9 is installed on the surface of the fixed ear 10. One end of the tension spring 9 is connected to the connecting ear 8.

[0032] When the external pressure pump pumps liquid into the C-shaped hollow frame 4, causing it to slide within the fixed slide 3, the tension spring 9 is stretched and stores energy. After irrigation ends and the pressure decreases, the tension spring 9 can pull the connecting ear 8 with its own elastic restoring force, thereby causing the C-shaped hollow frame 4 to automatically return to its initial position. This eliminates the need for manual operation, making it convenient and quick, and improving the ease of use and automation of the equipment.

[0033] Furthermore, the same adjusting plate 11 is installed on the outer side of multiple telescopic nozzles 5. A slider 13 is integrally formed on one side of the adjusting plate 11. An inclined plate 12 is fixedly installed on the surface of the fixed slide 3. A groove 14 adapted to the slider 13 is opened on the surface of the inclined plate 12. The adjusting plate 11 is slidably connected to the surface of the inclined plate 12 through the slider 13 and the groove 14.

[0034] The tips of dragon fruit branches are low to the ground, making them difficult to effectively cover with conventional irrigation methods. Through the coordinated action of the adjusting plate 11, tilting plate 12, slider 13, and chute 14, the telescopic nozzle 5 can move upwards while moving horizontally towards the plant. This allows the nozzle to precisely target the tips of the branches, ensuring these easily overlooked areas receive adequate irrigation. Sufficient water supply promotes growth and development, preventing the branches from drying out and stagnating due to water shortage, thereby improving the overall quality and yield of the fruit.

[0035] Furthermore, nozzles are installed at the outlets of multiple telescopic nozzles 5, and the nozzles are arranged in a duckbill shape.

[0036] The unique flat shape of the duckbill-shaped sprinkler head allows the water to be distributed in a fan shape, which greatly expands the coverage area of ​​a single irrigation compared to traditional round sprinklers. In dragon fruit greenhouses, this feature allows the sprinkler head to cover the fruit branches more comprehensively within a limited range of movement, especially the ends of those branches that are more scattered. By precisely controlling the angle of the fan-shaped spray, it can be ensured that every branch is evenly watered, reducing irrigation blind spots and ensuring that all parts of the dragon fruit plant receive sufficient water, promoting its overall balanced growth.

[0037] Example 2

[0038] Improvements based on Example 1:

[0039] Furthermore, a rotating shaft 16 is rotatably connected inside the I-beam frame 1, and a water-guiding tape 18 is wrapped around the surface of the rotating shaft 16. Multiple hooks 22 are installed at equal intervals on one side surface of the C-shaped hollow frame 4, and one end of the water-guiding tape 18 is hung on the multiple hooks 22.

[0040] This allows irrigation water to not only be sprayed onto the dragon fruit branches through the telescopic nozzle 5, but also to be precisely guided to the soil area around the plant roots with the help of the water-guiding tape 18, expanding the overall irrigation coverage and ensuring that each dragon fruit plant receives sufficient and appropriate water supply, promoting the overall growth of the plant.

[0041] Furthermore, a coil spring 17 is mounted on the surface of the rotating shaft 16, and the other end of the coil spring 17 is connected to the I-beam frame 1.

[0042] The coil spring 17 is installed between the rotating shaft 16 and the I-beam frame 1. After the irrigation operation is completed, it can automatically drive the rotating shaft 16 to rotate, and quickly and neatly retract the water-guiding tape 18 and wrap it around the rotating shaft 16. There is no need for manual labor to rewind it, which greatly saves manpower and time costs and improves the convenience of equipment operation.

[0043] Furthermore, a rubber scraper 19 is provided at one end of the I-beam frame 1. A T-shaped rod 20 is slidably connected in the through hole opened on the surface of the rubber scraper 19. One end of the T-shaped rod 20 is fixedly installed at the end of the I-beam frame 1, and a spring 21 is sleeved on the surface of the T-shaped rod 20. One end of the spring 21 abuts against the T-shaped structure of the T-shaped rod 20, and the other end of the spring 21 abuts against the rubber scraper 19.

[0044] When the water-wicking tape 18 is rolled up under the action of the coil spring 17, the rubber scraper 19 can stick tightly to its surface. During the movement of the water-wicking tape 18, the rubber scraper 19 will scrape off the residual dirt, impurities and unevaporated water on it. This not only ensures the cleanliness of the water-wicking tape 18 for the next use and ensures the cleaning effect, but also protects the water-wicking tape 18 to the greatest extent and extends its service life.

[0045] Furthermore, the I-beam frame 1 is integrally formed with multiple ground nails 2, and the ends of the multiple ground nails 2 are all set with a conical structure.

[0046] Multiple ground nails 2 are integrally formed on the I-frame 1. When installing the equipment, the ground nails 2 can be pressed into the soil of the greenhouse ground. Since the ends of the ground nails 2 are conical, this sharp shape can easily penetrate the soil and go deep into the ground. In this way, the entire irrigation equipment, including the I-frame 1 and the fixed slide 3 and C-shaped hollow frame 4 connected to it, is firmly fixed to the ground. During the irrigation operation, the equipment can also remain stable and will not shift or shake, ensuring that the telescopic nozzle 5 is always aligned with the predetermined irrigation area, thus ensuring the accuracy and continuity of the irrigation operation.

[0047] Working principle: When the dragon fruit grown in the smart agriculture greenhouse needs to be irrigated, the I-frame 1 with ground nails 2 is first placed in a suitable position. The cone-shaped structure at the end of the ground nail 2 is inserted into the soil to fix the entire irrigation equipment firmly and prevent the equipment from shifting during the irrigation process.

[0048] When irrigation is required, the external pressure pump connected to the pipe joint 15 is started. The pressure pump pumps water and other irrigation liquids into the C-shaped hollow frame 4 through the pipe joint 15. As the liquid is injected, the pressure inside the C-shaped hollow frame 4 increases, pushing the piston plate 6 to slide along the fixed rod 7 inside the C-shaped hollow frame 4. Since the piston plate 6 is connected to the fixed rod 7, the C-shaped hollow frame 4 will slide relative to the fixed slide 3. At the same time, the connecting ear 8 slides together with the C-shaped hollow frame 4 in the groove opened on the surface of the fixed slide 3. The tension spring 9 is in a stretched state. During the sliding of the C-shaped hollow frame 4, the positions of the multiple telescopic nozzles 5 installed on its surface also change accordingly. The adjustment plate 11 on the outside of the telescopic nozzle 5 slides in the groove 14 on the surface of the inclined plate 12 through the slider 13. This allows the telescopic nozzle 5 to move horizontally with the C-shaped hollow frame 4 and also to be adjusted at a certain angle along the tilt direction of the inclined plate 12. This allows for precise adjustment of the irrigation coverage area, so that the nozzles can cover the upward-growing and widely distributed fruit branches of the dragon fruit.

[0049] Because the nozzle at the outlet of the telescopic nozzle 5 is set in a duckbill shape, this special nozzle shape can make the sprayed water flow fan-shaped or ribbon-shaped, better covering the dragon fruit branches, ensuring that the branches can fully contact the water, and meeting their specific water needs during the vigorous growth period and the fruit enlargement period.

[0050] During irrigation, the soil beneath the dragon fruit plant can also be irrigated. Water-guiding tape 18 can be used, wrapped around the rotating shaft 16, with one end hung on the hook 22 on one side of the C-shaped hollow frame 4. As water sprays from the telescopic nozzle 5 to clean the fruit branches, the dripping water flows along the water-guiding tape 18 to the soil around the roots of the dragon fruit plant, irrigating the roots. Simultaneously, under the action of the coil spring 17, the rotating shaft 16 rotates, retracting the water-guiding tape 18. During this retraction, the rubber scraper 19 removes any remaining water from its surface. The scraping removes impurities. The rubber scraper 19 is connected to the I-frame 1 via a T-shaped rod 20 and a spring 21. The spring 21 ensures that the rubber scraper 19 is always in close contact with the surface of the water-guiding tape 18, ensuring the scraping effect. The scraped water is guided to the roots, which can realize the secondary use of water resources, improve the utilization rate of irrigation water, and alleviate water waste to a certain extent. This is in line with the water-saving concept of smart agriculture. At the same time, the soil mixture contains organic debris, microorganisms, etc. scraped from the surface or surrounding of the plant. After decomposition, these substances can provide additional nutrients for the dragon fruit plant and help the plant grow.

[0051] After irrigation is completed, the external pressure pump is turned off, the pressure inside the C-shaped hollow frame 4 decreases, and under the tension of the tension spring 9, the C-shaped hollow frame 4 slides back to its initial position. The telescopic nozzle 5 also returns to its initial state. The water-guiding tape 18 on the hook 22 is removed. With the coil spring 17 installed between the rotating shaft 16 and the I-beam frame 1, after the irrigation operation is completed, the rotating shaft 16 can be automatically driven to rotate, quickly and neatly retracting the water-guiding tape 18 and wrapping it around the rotating shaft 16. There is no need for manual labor to rewind it, which greatly saves manpower and time costs and improves the convenience of equipment operation.
