Description
Technical Field
[0001] This utility model belongs to the field of drip irrigation technology and equipment, and in particular relates to a small nutrient solution drip irrigation device. Background Technology
[0002] In greenhouse agriculture and home gardening, drip irrigation technology is widely used due to its water-saving and high-efficiency characteristics. However, existing drip irrigation systems have certain drawbacks: Fixed dripper design: In traditional drip irrigation systems, the drippers are usually fixed to the main pipe or branch pipe, making it impossible to flexibly adjust them horizontally according to the actual growth position of the plants. When planting density changes or plants shift, the drip irrigation solution is prone to deviating from the root absorption zone, leading to resource waste or uneven irrigation.
[0003] Lack of vertical adjustment function: Existing devices mostly use rigid structures, and the height of the dripper cannot be dynamically adjusted with the growth height of the plant. For example, the root distribution depth of seedlings and mature plants differs greatly, but the dripper is always kept at the same height, which may cause the shallow soil to be too wet or the deep roots to be short of water.
[0004] The aforementioned drawbacks limit the precision and applicability of drip irrigation technology. Especially in nutrient solution recycling systems, deviations in irrigation location can lead to decreased nutrient absorption efficiency in plants and even cause problems such as root rot. Therefore, there is an urgent need for a small drip irrigation device that can be freely adjusted according to different usage needs to meet the requirements of diverse planting scenarios.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0015] Examples, such as Figures 1-6As shown, a small nutrient solution drip irrigation device includes a drip irrigation device body. The drip irrigation device body includes an L-shaped mounting frame 1, which allows users to easily place the drip irrigation device body in a suitable position to ensure stability during use. A lifting and adjusting mechanism 2 is provided on the rear side of the mounting frame 1. This design allows adjustment of the vertical position of the drip irrigation head 10, so that the height of the drip head can be dynamically adjusted according to the growth height of the plant. The lifting end of the lifting and adjusting mechanism 2 is provided with a mounting base 3. A liquid holding tank 4 is provided inside the mounting base 3. The liquid holding tank 4 is used to store the nutrient solution to be dripped, and multiple [other components] are set on it. Each drip irrigation device has a liquid outlet connected to a drip head 10. Multiple drip irrigation units are installed, allowing communication between adjacent liquid tanks 4. A pump delivers nutrient solution to the liquid tanks 4, which then connects to the drip head 10 via a connecting pipe, ultimately discharging the solution through the drip head 10. This ensures smooth drip irrigation. The specific working method and principle of how the pump delivers the nutrient solution from the liquid tanks 4 to the drip head 10 are existing, mature, and commonly used technologies, and will not be elaborated further. Of course, how the drip irrigation process is implemented is also easily understood by those skilled in the art, and will not be discussed further here. To elaborate further, the mounting base 3 contains a T-shaped support frame 5. The mounting base 3 is positioned outside the support frame 5 to reinforce it and connects to the moving end of the lifting and adjusting mechanism 2, ensuring smooth subsequent lifting and adjusting operations. A connecting rod 6 is provided at the end of the support frame 5 to ensure the stability of the installation. A cover 7 is provided below the connecting rod 6, and a limit frame 8 is provided on the rear side of the cover 7 to limit the horizontal movement adjustment of the drip irrigation head 10. A telescopic translation mechanism 9 is provided on the front side of the limit frame 8. Utilizing the lifting and adjusting mechanism 2 and the telescopic translation mechanism 9, the drip irrigation head 10 can be adjusted according to the actual growth of the plant. The position and height of the drip irrigation point can be flexibly adjusted so that the drip irrigation head 10 is closer to the plant. By precisely positioning the drip irrigation position, the waste of nutrient solution is significantly reduced, ensuring that the nutrient solution is accurately delivered to the root absorption area, improving irrigation efficiency and resource utilization. At the same time, it reduces the risk of root diseases caused by uneven irrigation, greatly improving the practicality of the device. The telescopic translation mechanism 9 is equipped with a drip irrigation head 10. The drip irrigation head 10 is a commonly used drip irrigation device in the existing technology. It can receive the nutrient solution in the liquid tank 4 and deliver the nutrient solution to the root area of the plant, ensuring the smooth implementation of drip irrigation. In the above process: using the established lifting and adjusting mechanism 2 and telescopic translation mechanism 9, the position of the drip irrigation point can be flexibly adjusted according to the actual growth position and height of the plant, so that the drip irrigation head 10 is closer to the plant. Through the above-mentioned precise positioning of the drip irrigation position, the waste of nutrient solution is significantly reduced, ensuring that the nutrient solution is accurately delivered to the root absorption area, improving irrigation efficiency and resource utilization. At the same time, it reduces the risk of root diseases caused by uneven irrigation, greatly improving the practicality of the device. The device is reasonably designed, simple in structure, easy to process, and can achieve convenient adjustment in multiple positions, improving the functionality and applicability of the device and fully meeting the needs of use.
[0016] To facilitate vertical adjustment of the device, especially the vertical position of the drip irrigation head 10, the lifting and adjusting mechanism 2 includes a fixed base 21. A lead screw 22 is positioned between the upper and lower fixed bases 21. A handle 23 is positioned above the lead screw 22. A lead screw nut 24 is positioned on the outside of the lead screw 22. A hollow rectangular lifting frame 25 is positioned on the outside of the lead screw nut 24. Limiting plates 26 are positioned on both sides of the lifting frame 25 and are fitted onto the outside of the mounting frame 1. Limiting pulleys 27 are positioned on the outside of the lifting frame 25 located between the two limiting plates 26. Specifically, the hollow design of the lifting frame 25 allows for lightweight installation of the device. The connection between the lead screw nut 24 and the lead screw 22 is a conventional technical means. That is, when adjusting the position, the drive handle 23 rotates and acts on the lead screw 22. The rotation of the lead screw 22 can be converted into the vertical lifting and lowering movement of the lead screw nut 24, which in turn drives the lifting frame 25 and the equipment components set on it to adjust vertically, thereby completing the adjustment of the position of the drip irrigation head 10. This allows people to adjust it freely according to different usage needs. Of course, during use, the limit pulley 27 will rise and fall with the lifting frame 25, and its outer periphery abuts against the inner side of the mounting frame 1, making its vertical movement process smoother and more convenient, greatly improving the functionality of the device and meeting usage needs.
[0017] To further improve the rationality of the device setup, the limiting frame 8 includes a stabilizing frame 81 with an obtuse angle design. The upper and lower sides of the stabilizing frame 81 are provided with limiting strips 82 with a concave design. The stabilizing frame 81 is connected to the cover 7 and placed below the connecting rod 6 to ensure its stability. The limiting strips 82 limit the movement of the limiting pulley 27 in the telescopic translation mechanism 9 and improve the smoothness of its movement, providing convenient conditions for the adjustment process and meeting the usage requirements.
[0018] To facilitate convenient adjustment of the horizontal position of the drip head 10, the telescopic translation mechanism 9 includes a U-shaped or J-shaped movable frame 91. Limiting wheels 92 are provided at the upper and lower ends of the movable frame 91, corresponding appropriately to the limiting strip 82. That is, when the movable frame 91 moves under the drive of the telescopic adjustment component 11, the limiting wheels 92 are positioned within the limiting strip 82, limiting its direction of movement while ensuring smooth movement to meet usage requirements. The drip head 10 is housed within the movable frame 91. It should be further noted that the upper part of the drip head 10 is connected to the liquid container 4 to ensure smooth delivery of the nutrient solution. Of course, the drip head 10 and the liquid container 4 are connected by a pipe fitting. To ensure smooth conveying, the cover 7 has grooves adapted to the pipe fittings, facilitating their movement and preventing interference. To ensure smooth adjustment, a telescopic adjustment assembly 11 is provided on the outside of the moving frame 91. This assembly includes multiple cross-arranged connecting rods 111, arranged in the same scissor-like configuration as in existing technologies. The multiple connecting rods 111 enable the telescopic adjustment assembly 11 to have translational capabilities, especially in the horizontal direction. Furthermore, a rotating rod 112 is provided at the geometric center connection of two adjacent connecting rods 111, and is connected to the outside of the moving frame 91. Of course, the two intersecting connecting rods 111 rotate relative to each other. The connecting rods 111 of adjacent sets are also rotatably connected to ensure smooth adjustment. A connecting plate 113 is provided at the outermost end of the uppermost connecting rod 111, and a first slide block 114 is provided above the connecting plate 113. A first slide bar 115 is provided above the cover 7 corresponding to the first slide block 114. Two sets of the above structure are provided, and the outermost end of the uppermost connecting rod 111 can move relative to the upper inner side of the cover 7. Of course, the connecting plate 113 and the connecting rod 111 are also rotatably connected. When the connecting rod 111 is extended or retracted, the end of the connecting rod 111 can rotate relative to the connecting plate 113, and the connecting plate 113 can connect with the first slide block 114. 14 moves relative to the first slide bar 115 to adapt to the extension or retraction of the telescopic adjustment component 11, and ensures that the driving power can be smoothly applied to the moving frame 91 to meet the usage requirements. Of course, for the first slide bar 114, a vertical plate is set on it, and the connecting plate 113 can slide vertically relative to the vertical plate. That is to say, when the telescopic adjustment component 11 extends or retracts, the two ends of the connecting rod 111 on the outer upper side will descend or rise. This design can not only satisfy the movement of the connecting plate 113 relative to the first slide bar 115 to realize the movement of the horizontal position of the end of the connecting rod 111, but also satisfy the adjustment of the vertical position caused by extension and retraction, ensuring the smoothness of the movement process.A vertical plate 116 is provided at the end of the outermost connecting rod 111, and is rotatably connected to the connecting rod 111. A support plate 117 is provided on one side of the vertical plate 116, and the vertical plate 116 slides vertically relative to the support plate 117. A second slide block 118 is provided below the support plate 117, and a second slide bar 119 is provided on the lower inner side of the cover 7 corresponding to the second slide block 118. The above design is the same as the movement mode of the upper end of the outermost connecting rod 111. That is to say, when adjusting, the end of the outermost lower connecting rod 111 can move horizontally with the second slide block 118 and the second slide bar 119, and can also move vertically relative to the support plate 117 with the help of the vertical plate 116, ensuring smooth operation. As for the movement of the telescopic adjustment component 11, a drive rod is provided outside the second slide block 118 and passes through the cover 7. A locking nut is provided outside the drive rod. When it is necessary to adjust the drip head... When adjusting the position of the drip head 10, the user moves the drive rod horizontally, causing the second slide block 118 to move relative to the second slide bar 119. This driving force acts on the support plate 117, causing the vertical plate 116 to bear the horizontal force. With the help of the connecting rod 111, the telescopic adjustment component 11 moves horizontally, thus facilitating the adjustment of the drip head 10's position. Alternatively, the drive rod can be located outside the upper first slide block 114, allowing force to be applied simultaneously on both drive rods during adjustment, ensuring ease of adjustment. Furthermore, it should be noted that the movable frame 91 in the middle position does not move with the telescopic adjustment component 11, serving as a limit for the device's operation. In other words, while the movable frames 91 on either side of the middle movable frame 91 move, the middle movable frame 91 acts as a positioning limit, ensuring the device's functionality.
[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
