Description

Technical Field

[0001] The present invention relates to the technical field of irrigation equipment, and specifically to a buried water and fertilizer integrated seedling root water-saving irrigation device. Background Art

[0002] The buried water and fertilizer integrated seedling root water-saving irrigation device is a water-saving irrigation system that combines irrigation and fertilization and buries the equipment underground. With the help of a pressure system or the natural head of the terrain, soluble solid or liquid fertilizers are formulated into fertilizer solutions, which, together with irrigation water, uniformly, regularly, and quantitatively infiltrate the root growth area of crops through pipelines and drip heads, keeping the soil of the main roots always loose and with appropriate water content. It has the advantages of water saving, fertilizer saving, environmental protection, high efficiency, etc., and is widely used in modern agriculture.

[0003] However, the diameter of the liquid dripping holes opened on the buried irrigation pipe is fixed and cannot be adjusted, which to a certain extent limits the flexibility and accuracy of the irrigation system. Due to the fixed diameter of the liquid dripping holes, the irrigation water volume and fertilization amount cannot be adjusted according to the needs of different growth stages of crops, which may lead to over-irrigation or insufficient fertilization, affecting the growth and yield of crops. Therefore, we propose a new type of buried water and fertilizer integrated seedling root water-saving irrigation device. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a buried water and fertilizer integrated seedling root water-saving irrigation device to solve the problems caused by the fixed diameter of the liquid dripping holes of the buried irrigation pipe, which cannot adjust the irrigation water volume and fertilization amount, limits the flexibility and accuracy of the irrigation system, and is prone to over-irrigation or insufficient fertilization, affecting the growth and yield of crops.

[0005] To achieve the above object, the present invention provides the following technical solution: A buried water and fertilizer integrated seedling root water-saving irrigation device, including a plurality of unit pipelines, a plurality of soil moisture detection sensors are fixedly installed on the outer circumferential surface of the plurality of unit pipelines, and a water outlet structure is arranged at one end of the unit pipeline.

[0006] The water outlet structure includes a water outlet pipe fixedly installed at one end of the unit pipeline, annular baffles adapted to the water outlet pipe are symmetrically installed on the inner circumferential surface of the water outlet pipe, a plurality of arc-shaped blocks adapted to the annular baffles are slidably connected to the inner side of the annular baffles, a support rod is fixedly installed on the arc-shaped block, and a shaft ring is fixedly installed at the end of the support rod away from the arc-shaped block, and the shaft ring and the water outlet pipe are on the same axis.

[0007] Preferably, a plurality of water outlet holes are opened on the water outlet pipe, an inner conical filter screen is fixedly installed in the inner cavity of the water outlet hole, and an outer conical filter screen symmetrical to the inner conical filter screen is fixedly installed on the inner conical filter screen.

[0008] Preferably, both the inner conical filter screen and the outer conical filter screen are made of stainless steel materials.

[0009] Preferably, an anti-blocking ring coaxial with the water outlet pipe is arranged on the outer side of the outer conical filter screen, and the anti-blocking ring is fixedly connected with the water outlet pipe; a plurality of water overflow holes are formed in the anti-blocking ring.

[0010] Preferably, the number of the shaft rings is several, a shaft rod is fixedly installed on the several shaft rings, a first bevel gear is fixedly installed at one end of the shaft rod, a second bevel gear is meshed outside the first bevel gear, a rotating rod penetrating through one of the unit pipes is fixedly installed on the second bevel gear, a servo motor is fixedly installed at the top end of the rotating rod, and a motor bracket is fixedly installed outside the servo motor, wherein the motor bracket is fixedly connected with one of the unit pipes.

[0011] Preferably, the several unit pipes and the several water outlet pipes are connected to each other in an alternating manner.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By arranging the rotatable arc-shaped baffle to cooperate with the water outlet holes, the precise adjustment of the irrigation water volume and fertilization amount is realized, and the problem that the diameter of the drip holes of the traditional irrigation device is fixed and the irrigation water volume and fertilization amount cannot be adjusted according to the needs of different growth stages of crops is solved. The present invention can flexibly adjust the cross-sectional area of the water outlet holes by adjusting the overlapping degree of the arc-shaped baffle and the water outlet holes, thereby realizing the precise control of the irrigation water volume and fertilization amount, avoiding the situations of over-irrigation or insufficient fertilization, and improving the growth efficiency and yield of crops.

[0014] 2. By arranging the inner conical filter screen and the outer conical filter screen, the fertilizer particles and impurities in the soil are effectively prevented from blocking the water outlet holes, and the stability and reliability of the irrigation system are improved. Due to the lack of an effective filtering mechanism, the traditional irrigation device is prone to the problem of water outlet hole blockage. However, through the double-layer filtering design of the present invention, the mixed liquid is firstly preliminarily filtered by the inner conical filter screen to remove larger fertilizer particles and impurities, and then the outer conical filter screen is used for secondary filtering to further ensure the unobstructed water outlet holes. At the same time, the anti-blocking ring further reduces the possibility of impurities such as stones and soil blocks in the soil blocking the water outlet holes. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In the present invention, unless otherwise stated, the directions such as "upper, lower" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually relative to the left and right shown in the drawings; "inner, outer" refer to the inner and outer of the contours of each component itself, but the above orientation terms do not limit the present invention.

[0025] The present invention provides a technical solution:

[0026] Please refer to Figures 1 to 7 , a buried water and fertilizer integrated water-saving irrigation device for nursery stock roots, comprising a plurality of unit pipelines 1, a plurality of soil moisture detection sensors 2 are fixedly installed on the outer circumferential surface of the plurality of unit pipelines 1, and a water outlet structure 3 is arranged at one end of the unit pipeline 1.

[0027] The water outlet structure 3 includes a water outlet pipe 301 fixedly installed at one end of the unit pipeline 1. Symmetrically installed on the inner circular surface of the water outlet pipe 301 are annular baffles 302 adapted to the water outlet pipe 301. Slidably connected to the inner side of the annular baffle 302 are a number of arc-shaped stoppers 303 adapted to the annular baffle 302. Fixedly installed on the arc-shaped stopper 303 is a support rod 304. Fixedly installed at one end of the support rod 304 away from the arc-shaped stopper 303 is a collar 305, and the collar 305 and the water outlet pipe 301 are on the same axis line.

[0028] In the water outlet structure 3, one end of the water outlet pipe 301 is fixed to the unit pipeline 1. Slidably connected to the inner side of the annular baffle 302 installed on its inner circular surface are a number of arc-shaped stoppers 303, which are connected to the collar 305 through the support rod 304. The collar 305 and the water outlet pipe 301 are coaxial. This design adjusts the opening degree of the water outlet holes 306 through the sliding of the arc-shaped stoppers 303, thereby accurately controlling the irrigation water volume and fertilization amount, and flexibly responding to the needs of different growth stages of crops.

[0029] Please refer to Figure 2 and Figures 5 to 7 A number of water outlet holes 306 are opened on the water outlet pipe 301. Fixedly installed in the inner cavity of the water outlet hole 306 is an inner conical filter screen 307. Fixedly installed on the inner conical filter screen 307 is an outer conical filter screen 308 symmetric to the inner conical filter screen 307. Both the inner conical filter screen 307 and the outer conical filter screen 308 are made of stainless steel material.

[0030] Inside the water outlet holes 306 opened on the water outlet pipe 301, there are an inner conical filter screen 307 and an outer conical filter screen 308, both made of stainless steel material, forming a double filtration system. During irrigation, the double filter screens effectively intercept fertilizer particles and soil impurities, preventing the blockage of the water outlet holes 306, ensuring the smooth outflow of the water and fertilizer mixture. At the same time, the stainless steel material is corrosion-resistant, extending the service life of the device and ensuring the stability and durability of the irrigation system.

[0031] Please refer to 5 to Figure 7 As shown in the figure, on the outer side of the outer conical filter screen 308, there is an anti-blocking ring 309 coaxial with the water outlet pipe 301, and the anti-blocking ring 309 is fixedly connected to the water outlet pipe 301; a number of overflow holes are opened on the anti-blocking ring 309.

[0032] During irrigation, the anti-blocking ring 309 effectively blocks larger impurities such as stones and soil clods in the soil from entering the water outlet holes 306, ensuring the continuous operation of the irrigation system, improving the irrigation efficiency and the overall reliability of the system.

[0033] Please refer to Figures 1 to 7, the number of collar 305 is several. A shaft rod 310 is fixedly installed on several collars 305. A first bevel gear 311 is fixedly installed at one end of the shaft rod 310. A second bevel gear 312 is engaged with the outside of the first bevel gear 311. A rotating rod 313 passing through one of the unit pipes 1 is fixedly installed on the second bevel gear 312. A servo motor 314 is fixedly installed at the top of the rotating rod 313. A motor bracket is fixedly installed on the outside of the servo motor 314, and the motor bracket is fixedly connected to one of the unit pipes 1.

[0034] The collar 305 is fixedly connected to the shaft rod 310 to form the core component of the transmission system. The servo motor 314 is fixed to the unit pipe 1 through the motor bracket, driving the rotating rod 313 and the second bevel gear 312 to rotate, and then driving the first bevel gear 311 and the shaft rod 310 to rotate, realizing the rotational adjustment of the arc-shaped block 303. This design automatically adjusts the opening degree of the water outlet hole 306 when the soil humidity changes, accurately controls the irrigation water volume and fertilization amount, and improves the irrigation efficiency and flexibility.

[0035] Please refer to Figure 1 and Figure 2 , several unit pipes 1 are cross-connected with several water outlet pipes 301.

[0036] The unit pipes 1 and the water outlet pipes 301 are cross-connected to form a complete and orderly irrigation pipeline. During the working process, this layout ensures that the water and fertilizer mixture can be evenly distributed to the root area of the crops, realizing all-round irrigation.

[0037] When specifically used, the working principle of the present invention is as follows:

[0038] When using this device, first bury the pipeline beside the roots of the seedlings to be irrigated, fixedly connect the external liquid supply system to one end of the pipeline, and connect the other end of the pipeline to the liquid return system to form a complete irrigation system. The mixture is composed of water and fertilizer.

[0039] When irrigating the roots of the seedlings, it is necessary to stagger the arc-shaped block 303 from the water outlet hole 306, and the water inside several unit pipes 1 will overflow from the water outlet hole 306 to irrigate the roots of the seedlings.

[0040] The inner conical filter screen 307 is used to initially filter the impurities in the water and fertilizer solution to prevent fertilizer particles from blocking the water outlet hole 306. The outer conical filter screen 308 is used to further filter the impurities in the water and fertilizer solution. The anti-blocking ring 309 is used to prevent impurities such as stones and soil blocks in the soil from blocking the water outlet hole 306, improving the stability and reliability of the irrigation system.

[0041] When the irrigation water volume and fertilizer application volume are adjusted according to the needs of different growth stages of crops, when the soil moisture detection sensor 2 detects that the water content in the root area is higher than the set threshold, the servo motor 314 drives the rotating rod 313 to rotate forward, the rotating rod 313 drives the second bevel gear 312 to rotate, the second bevel gear 312 drives the first bevel gear 311 to rotate, the first bevel gear 311 drives the shaft 310 to rotate, and the shaft 310 drives the shaft ring 305, the support rod 304 and the arc block 303 to rotate, causing the arc block 303 to gradually overlap with the water outlet 306, thereby reducing the cross-sectional area of ​​the water outlet 306 and reducing the output of the mixed liquid of water and fertilizer.

[0042] When the soil moisture detection sensor 2 detects that the water content in the root area is lower than the set threshold, the servo motor 314 drives the rotating rod 313 to rotate in the opposite direction, the rotating rod 313 drives the second bevel gear 312 to rotate, the second bevel gear 312 drives the first bevel gear 311 to rotate, the first bevel gear 311 drives the shaft 310 to rotate, the shaft 310 drives the shaft ring 305, the support rod 304 and the arc block 303 to rotate, causing the arc block 303 to gradually stagger with the water outlet 306, thereby increasing the cross-sectional area of ​​the water outlet 306 and increasing the output of the mixed liquid of water and fertilizer.

[0043] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
