Description

Technical Field

[0001] This invention relates to the field of fertilization-related technologies, and in particular to a water and fertilizer integrated sprinkler irrigation device based on wheat breeding. Background Technology

[0002] Wheat breeding is a key technology for creating high-yielding, stress-resistant, and high-quality new varieties through genetic improvement. Traditional breeding relies on phenotypic selection, which is time-consuming (usually 8-15 years) and inefficient. Modern breeding combines marker-assisted selection (MAS), double haploid (DH) technology, and gene editing to significantly shorten the breeding cycle and improve accuracy. Integrated water and fertilizer management (such as drip / sprinkler irrigation) can optimize field trial conditions and reduce the interference of environmental variations on trait evaluation. Currently, global wheat breeding focuses on disease resistance (such as Fusarium head blight and rust), tolerance to abiotic stresses (drought, salinity), and quality improvement (protein content, processing characteristics). To ensure the consistency of the growth environment of breeding materials, improve the reliability of phenotypic data, accelerate stress resistance screening, and significantly improve breeding efficiency and selection accuracy, it is necessary to implement water and fertilizer sprinkler irrigation in experimental fields.

[0003] Regarding fertilization technology, existing technologies include Chinese Patent Publication No. CN222997033U, which discloses a fertilization device for wheat breeding. This utility model relates to the field of wheat breeding technology. This wheat breeding fertilization device includes a trolley with a fertilization device mounted on top for fertilizing wheat. The fertilization device includes a stirring unit for stirring the fertilizer to prevent it from piling up and thus reducing its effectiveness; and a heating unit for heating the fertilizer inside the fertilizer tank to prevent it from freezing due to low temperatures, thus rendering it unusable. This utility model, by installing a stirring unit and then starting a motor, causes the motor to drive a rotating shaft to rotate. This rotation causes the stirring component to stir the fertilizer inside the fertilizer tank. Simultaneously, the motor's operation causes a transmission component to drive a scraper component to move, further scraping away fertilizer adhering to the inner surface of the fertilizer tank.

[0004] The aforementioned existing technologies mainly address the problems that exist during the mixing process of fertilizers, but they do not take into account the insufficient water supply caused by excessively long delivery pipelines, which leads to uneven flow of water and fertilizer solution to each sprinkler structure, easily resulting in uneven sprinkler irrigation and insufficient range. Furthermore, the existing sprinkler structures are fixed and cannot dynamically adjust the sprinkler distance according to the flow of water and fertilizer solution. Based on this, this application designs a water and fertilizer integrated sprinkler irrigation device based on wheat breeding. Summary of the Invention

[0005] The purpose of this invention is to provide a water and fertilizer integrated sprinkler irrigation device based on wheat breeding, which aims to improve sprinkler irrigation efficiency.

[0014] As a preferred embodiment of the present invention, the sprinkler head includes an inner sprinkler cylinder, which is fitted inside the outer sprinkler cylinder. A limiting slider is provided on one side of the outer wall of the inner sprinkler cylinder.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. Improved irrigation uniformity: The design of the filter diversion component and V-shaped parts optimizes the diversion effect of water and fertilizer solution, ensuring balanced flow in each diversion pipe and avoiding the problem of insufficient water supply caused by excessively long pipes in traditional devices, thus significantly improving the uniformity of irrigation.

[0021] 2. Dynamically Adjustable Irrigation Range: The sprinkler head and sprinkler assembly work together to achieve dynamic adjustment of the irrigation distance through up-and-down sliding and a multi-hole structure (hole one, hole two, hole three). When sufficient water and fertilizer solution enters, the maximum height of the inner cylinder of the sprinkler system results in a larger space between the inner and outer cylinders, allowing for sufficient water and fertilizer solution to enter. This reduces the structural deformation caused by excessive internal pressure due to insufficient space. When less water and fertilizer solution enters, the space between the inner and outer cylinders is smaller, allowing the inner cylinder to be lifted after the water and fertilizer solution fills the space, thus enabling medium and short-distance irrigation. This adapts to different flow requirements, making the irrigation range more flexible and controllable.

[0022] 3. Easy and stable installation: The bottom positioning component and the edge-expanding mechanism work together to quickly fix the device in the soil through spiral descent and edge-expanding support, while avoiding soil interference with the threaded structure, thus improving installation efficiency and stability.

[0030] The following is in conjunction with the appendix Figures 1 to 6 This application will be described in further detail.

[0031] This application discloses a water and fertilizer integrated sprinkler irrigation device based on wheat breeding. This application performs sprinkler irrigation operations on bred wheat in experimental fields, and increases the flow rate of liquid reaching each sprinkler structure during the water and fertilizer liquid transportation process, thereby improving the uniformity of the spray volume of each sprinkler structure.

[0032] Reference Figures 1 to 3 As shown in this embodiment, a water and fertilizer integrated sprinkler irrigation device based on wheat breeding is disclosed, including a main pipe 1, a branch pipe 2, a filter and branch component 3, a sprinkler irrigation component 4, a connecting pipe 5, a sprinkler head 6, a lower insertion positioning component 7, and a rim-expanding mechanism 8. The main pipe 1 is symmetrically connected with the branch pipe 2 on both sides. The filter and branch component 3 is located inside the main pipe 1. The sprinkler irrigation component 4 is connected to the branch pipe 2 through the connecting pipe 5 with a blocking function. The upper end of the sprinkler irrigation component 4 is provided with a sprinkler head 6 that can slide up and down. The spray direction is controlled by the cooperation between the sprinkler irrigation component 4 and the upper and lower sliding sprinkler head 6. The lower insertion positioning component 7 is connected to the lower end of the sprinkler irrigation component 4 by a threaded engagement. The rim-expanding mechanism 8 is evenly arranged around the lower end of the sprinkler irrigation component 4. The spirally descending lower insertion positioning component 7 and the rim-expanding mechanism 8 form a squeezing motion, causing the rim-expanding mechanism 8 to extend outward.

[0033] In actual sprinkler irrigation, the main pipe 1 of this application is assembled with the main pipeline (existing technology) for transporting water and fertilizer solution. The main pipes 1 are intermittently distributed, with the spacing between adjacent main pipes 1 controlled at 12-14 meters. Based on the current experimental field environment, the sprinkler assembly 4 is selectively connected to the branch pipes 2 at different locations (the outlet of the unconnected branch pipe 2 can be temporarily sealed with the existing sealing cap). Subsequently, the positioning assembly 7 is spirally lowered (at this time, the sprinkler assembly 4 and the sprinkler head 6 are unlocked, and the internal flow of the connecting pipe 5 can be smooth), descending to the lowest position. At the low position, the edging mechanism 8 extends outward as a whole, dragging the irrigation component 4 to the irrigation position and then inserting it into the soil for positioning through the lower positioning component 7 (the extended edging mechanism 8 provides bottom support for the irrigation component 4). After being inserted and positioned in sequence, the water pump connected to the main pipeline for transporting water and fertilizer solution is turned on, and the water and fertilizer solution is transported to the main pipeline through the existing water pump, and then distributed to each branch pipe 2. The irrigation head 6 moves upward under the impact of the water and fertilizer solution, and the water and fertilizer solution delivered is effectively sprayed out through the cooperation between the irrigation component 4 and the irrigation head 6.

[0034] The following points should be noted: 1. For main pipe 1, the impurities intercepted inside need to be periodically removed through the filter diversion component 3; 2. Sprinkler irrigation should be suspended during windy weather (> level 4); 3. In summer, it is advisable to operate between 20:00 and 6:00 to reduce evaporation loss by more than 30%.

[0035] Reference Figure 2 As shown, the diversion pipe 2 has a structure that gradually slopes outwards from front to back. The design of the inclined structure facilitates the entry of water and fertilizer solution into the diversion pipe 2, thereby increasing the diversion flow rate. The middle part of the diversion pipe 2 is a telescopic hose structure. The setting of the telescopic hose increases the freedom of installation position of the sprinkler assembly 4 connected to the diversion pipe 2. The rear end of the diversion pipe 2 is rotatably connected to an internal thread head 21.

[0036] Reference Figure 2 As shown, due to the long length of the main pipeline, the amount of water and fertilizer solution that flows into the diversion pipe 2 may be uneven during internal transportation, resulting in a smaller amount of water and fertilizer solution being sprayed out from the sprinkler assembly 4. Therefore, this application designs a filter diversion assembly 3 to increase the flow rate of water and fertilizer solution when it passes through the diversion pipe 2. The specific structure is as follows: the filter diversion assembly 3 includes a filter component 31, which is inserted vertically from top to bottom into the front end of the main pipe 1. A V-shaped component 32 is installed in the middle of the main pipe 1, with the pointed end of the V-shaped component 32 facing forward. A flow groove is provided on the V-shaped component 32, and the interior of the flow groove is connected to the front end of the wave component 33 through a pin.

[0037] In actual operation, when the water and fertilizer solution enters the main pipe 1, it is filtered and intercepted by the filter component 31. The filter component 31 is detachable and can be pulled out periodically to clean the impurities intercepted in the filter component 31. When the water and fertilizer solution passes through the V-shaped component 32, it has a certain effect of diverting the flow to both sides, which increases the amount of water and fertilizer solution entering the diversion pipe 2. When the water and fertilizer solution passes through the wave component 33, it has a buffering effect, which slows down the flow of the water and fertilizer solution when it passes through this part, which also increases the amount of water and fertilizer solution entering the diversion pipe 2.

[0038] Reference Figure 1 As shown, this application controls the spraying direction through the cooperation between the irrigation assembly 4 and the vertically sliding irrigation head 6. The specific structure of the two is as follows: the irrigation assembly 4 includes a connecting pipe 41, a limiting plate 42 with an inverted T-shaped structure installed at the lower end of the connecting pipe 41, an irrigation outer cylinder 43 installed at the upper end of the connecting pipe 41, and irrigation holes 44 evenly arranged along the circumference of the outer wall of the irrigation outer cylinder 43. A locking component 45 is horizontally slidably arranged between the connecting pipe 41 and the irrigation outer cylinder 43.

[0039] Reference Figure 6 As shown, the irrigation nozzle 44 has three holes from bottom to top: hole 441, hole 442, and hole 443. Hole 441 is gradually inclined downwards from the inside out, hole 442 is a horizontal straight line, and hole 443 is gradually inclined upwards from the inside out. Under the impact of the water and fertilizer solution, the inner cylinder 61 of the irrigation system rises irregularly. At this time, the corresponding hole 63 in the inner cylinder 61 and the irrigation nozzle 44 are partially or completely aligned. The structural design of holes 441, 442, and 443 makes the irrigation distance farther the irrigation inner cylinder 61 rises higher. Therefore, when the impact force of the water and fertilizer solution is insufficient, it is difficult for the corresponding hole 63 in the inner cylinder 61 and the hole 443 in the irrigation nozzle 44 to maintain alignment for a long time. As a result, when the water and fertilizer solution input is insufficient, most of the water and fertilizer solution is sprayed out from holes 441 and 442, thus enabling medium and short-distance irrigation.

[0040] Reference Figure 4 , 6As shown, the locking component 45 includes a U-shaped component 451. The lower end of the U-shaped component 451 is horizontally slidably disposed in the built-in groove of the connecting pipe 41, and the upper end of the U-shaped component 451 is horizontally slidably disposed in the snap-fit ​​groove 431 of the sprinkler outer cylinder 43. An elastic reset component 452 is connected between the middle part of the U-shaped component 451 and the outer wall of the connecting pipe 41. A T-shaped slider 453 is disposed on the inner side of the upper end of the U-shaped component 451. The T-shaped slider 453 is provided to ensure that the U-shaped component 451 can drive the snap-fit ​​block 454 to move horizontally. The T-shaped slider 453 is vertically slidably disposed in the T-shaped groove 455 of the snap-fit ​​block 454. When not inserted into the soil in this application (possibly...), (While in transit and unopened) the position between the outer irrigation cylinder 43 and the inner irrigation cylinder 61 is locked by the horizontal insertion of the U-shaped piece 451. At this time, half of the locking block 454 is in the inner groove 611 and the other half is in the locking groove 431, thereby locking the position (longitudinal position) between the outer irrigation cylinder 43 and the inner irrigation cylinder 61. After the lower end of the U-shaped piece 451 is no longer squeezed, the U-shaped piece 451 is elastically reset under the action of the elastic reset piece 452. After reset, the locking block 454 is completely in the inner groove 611, while the upper end of the U-shaped piece 451 is in the locking groove 431, thus unlocking the longitudinal position between the outer irrigation cylinder 43 and the inner irrigation cylinder 61.

[0041] Reference Figure 3 , Figure 6 As shown, the sprinkler head 6 includes an inner sprinkler cylinder 61, which is fitted inside the outer sprinkler cylinder 43. A limiting slider 62 is provided on one side of the outer wall of the inner sprinkler cylinder 61. The limiting slider 62 is slidably disposed in a limiting groove opened in the inner wall of the outer sprinkler cylinder 43, limiting the upward path of the inner sprinkler cylinder 61. Corresponding holes 63 are evenly opened along the circumference of the outer wall of the inner sprinkler cylinder 61. The positions of the sprinkler hole component 44 and the corresponding holes 63 are corresponding. The upper middle part of the connecting pipe 41 is connected to the lower end of the adjusting component 64. The middle part of the adjusting component 64 is located in the upper middle part of the inner sprinkler cylinder 61. An embedded groove is opened on the other side of the outer wall of the inner sprinkler cylinder 61. 611, the lower half of the outer end of the inner groove 611 is an open structure. Due to the presence of the T-shaped slider 453, when the snap-fit ​​block 454 is completely in the inner groove 611, the T-shaped slider 453 also enters the inner groove 611. If there were no such open structure, the T-shaped slider 453 entering the inner groove 611 would lock the longitudinal position between the outer cylinder 43 and the inner cylinder 61. The opening structure allows the T-shaped slider 453 to pass through the opening structure instead of being blocked when the inner cylinder 61 is lifted up. The inner half of the snap-fit ​​block 454 is slidably disposed in the inner groove 611, and the outer half of the snap-fit ​​block 454 is snapped into the snap-fit ​​groove 431.

[0042] Before actual delivery, the lower positioning component 7 is spirally lowered. After lowering, the lower positioning component 7 no longer limits the lower end of the blocking ball 53 and the U-shaped part 451. At this time, the U-shaped part 451 moves horizontally under the action of the elastic reset part 452, so that the snap-fit ​​block 454 is completely inserted into the inner groove 611 (the snap-fit ​​block 454 no longer forms a snap-fit ​​effect with the snap-fit ​​groove 431). At this time, the position between the outer irrigation cylinder 43 and the inner irrigation cylinder 61 is unlocked. After the water and fertilizer liquid enters the connecting pipe 41, under the impact of the water and fertilizer liquid, the inner irrigation cylinder 61 is irregularly pushed upward. At this time, the position between the corresponding hole 63 in the inner irrigation cylinder 61 and the irrigation hole part 44 is partially or completely aligned, thereby spraying out the water and fertilizer liquid.

[0043] Reference Figure 3 As shown, this application uses a control adjustment component 64 to pre-adjust the spray range. Its specific structure is as follows: the adjustment component 64 includes a connecting column 641. The lower end of the connecting column 641 is installed in the middle of the upper end of the connecting pipe 41 through a fixing rod. The upper end of the connecting column 641 is connected to the lower end of the threaded rod 642 through a threaded engagement. A rotating head 643 is installed on the upper end of the threaded rod 642. A limit ring 644 is rotatably provided on the lower end of the rotating head 643. A connecting spring 645 is connected between the limit ring 644 and the upper end face of the inner cylinder 61 of the sprayer.

[0044] In specific situations where long-distance or medium-to-long-distance irrigation is not required, the hand-held rotating head 643 is rotated to cause the threaded rod 642 to descend in a spiral manner, thereby reducing the height of the limiting ring 644. At this time, the rising height of the inner irrigation cylinder 61 is reduced and limited, and the corresponding hole 63 on the inner irrigation cylinder 61 cannot be aligned with the second hole 442 and the third hole 443 of the irrigation hole component 44 even if it rises.

[0045] Reference Figure 3 As shown, the connecting pipe 5 includes a branch pipe 51. An external threaded head 52 is installed at the end of the branch pipe 51 away from the connecting pipe 41. A blocking ball 53 that can block the flow of liquid is provided inside the branch pipe 51. The middle part of the blocking ball 53 is connected to the connecting rod 55 through a multi-section telescopic rod 54. The connecting rod 55 is fixedly installed in the middle of the branch pipe 51. The cross-section of the connecting rod 55 is a triangular structure.

[0046] During actual operation, when the lower positioning component 7 is not spirally descending, the side of the conical head 72 will press against one side of the blocking ball 53, causing the blocking ball 53 to enter the branch pipe 51 for blocking (the inner diameter of the branch pipe 51 is equal to the diameter of the blocking ball 53). When the side of the conical head 72 no longer presses against one side of the blocking ball 53, the subsequent impact of the liquid will push the blocking ball 53 in the branch pipe 51 into the connecting pipe 41, at which point the liquid can pass through smoothly.

[0047] ReferenceFigure 3 , Figure 5 As shown, this application further improves the structure of the lower insertion positioning component 7 and the edge expansion mechanism 8 to facilitate storage and transportation. The specific structure is as follows: The lower insertion positioning component 7 includes a threaded part 71, and a conical head 72 is installed at the upper end of the threaded part 71. The conical head 72 at the initial height abuts and limits one side of the blocking ball 53. A lower plug 73 is installed at the lower end of the threaded part 71. A multi-segment telescopic cylinder 74 is installed around the upper end of the lower plug 73. A limit ring 75 is installed at the upper end of the telescopic cylinder 74. The telescopic cylinder 74 and the limit ring 75 are designed to prevent the soil from contacting the threaded structure of the threaded part 71, thereby increasing the resistance to subsequent thread rotation. When the lower insertion positioning component 7 is inserted into the soil, the limit ring 75 will adhere to the surface of the soil layer in the middle and later stages, and the telescopic cylinder 74 will extend, thereby preventing the soil from directly contacting the threaded part 71 inserted into the soil layer.

[0048] Reference Figure 5 As shown, the edge-expanding mechanism 8 includes an edge-expanding plate 81, which is horizontally slidably disposed in the storage groove 421 opened in the limiting plate 42. The edge-expanding plate 81 and the storage groove 421 are elastically connected. The inner inclined surface of the edge-expanding plate 81 is squeezed and cooperated with the extrusion roller 83 rolled at the lower end of the extrusion rod 82. The extrusion rod 82 is slidably disposed in the storage groove 421.

[0049] In actual operation, the spiral descending threaded part 71 and the conical head 72 descend in sequence to contact the extrusion rod 82. Then the two descend synchronously, and the descending extrusion rod 82 extrudes the entire expansion plate 81. When the lower plug 73 descends to the lowest position, the exposed part of the lower insertion positioning component 7 is at its maximum and reaches its longest value. At this time, the expansion plate 81 has also extended to its maximum value.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
