On the one hand, it cannot accurately adjust the irrigation water volume and fertilizer concentration in real time according to the water and fertilizer requirements of walnut trees at different growth stages; on the other hand, the equipment has low integration, is complicated to operate, and has a high threshold for farmers to use, making it difficult to promote and apply on a large scale.

[0004] Therefore, it is urgent to develop a precision drip irrigation device that integrates water and fertilizer for walnut trees. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems in the prior art, and to propose a precision drip irrigation device for walnut trees that integrates water and fertilizer and its usage method.

[0008] Preferably, the stirring mechanism includes a stirring shaft that rotates inside the storage tank via bearings. Several stirring blades are fixedly connected to the surface of the stirring shaft. The several stirring blades are symmetrically arranged along the center line of the stirring shaft. A bevel gear one is fixedly connected to one end of the stirring shaft. A bevel gear two is meshed with the surface of the bevel gear one. The bevel gear two is fixedly connected to the output shaft of the fertilizer pump.

[0009] Preferably, the top of the liquid storage tank is provided with a linkage mechanism, which is used to clean the impurities intercepted on the filter screen.

[0010] Preferably, the linkage mechanism includes a T-shaped rotating rod that rotates on the top of the storage tank via a bearing. One end of the T-shaped rotating rod is inserted into the inside of the stirring shaft. A rotating rod is rotatably provided on the surface of the T-shaped rotating rod. A push rod is rotatably connected to the end of the rotating rod via a rotating shaft. The end of the push rod passes through the feed hopper and is fixedly connected to a cleaning plate.

[0011] Preferably, a baffle is rotatably connected to one side of the feed hopper via a rotating shaft, and a through groove is provided on one side of the feed hopper. The baffle is used to seal one side of the through groove.

[0012] Preferably, the adjusting mechanism includes a clamp installed on the surface of the drip irrigation tape, a rotating component fixedly connected to the bottom of the clamp, a plurality of fixed rods fixedly connected to the bottom of the rotating component, and an adjusting rod sleeved on the surface of each of the fixed rods.

[0013] Preferably, the rotating component includes a fixed plate fixed to the bottom of the clamp, a rotating disk at the bottom of the fixed plate, a T-shaped annular groove inside the fixed plate, a T-shaped slider rotatably connected inside the T-shaped annular groove, and the end of the T-shaped slider being fixed to the top of the rotating disk.

[0014] Preferably, a torsion spring is provided on one side of the baffle, and the end of the torsion spring is fixedly connected to the side of the feed hopper.

[0015] Preferably, a protective shell is fixedly connected to the bottom of the storage tank, and the protective shell is fitted onto the surface of the stirring shaft and the stirring blade.

[0016] A method for using a precision drip irrigation device for walnut trees that integrates water and fertilizer mainly includes the following steps:

[0017] S1. Preparation stage: Add a certain amount of fertilizer and an appropriate amount of water to the storage tank through the feed hopper, and start the stirring mechanism to fully dissolve and mix the fertilizer to form a fertilizer solution.

[0018] S2. During the mixing stage, bevel gear one is driven by bevel gear two to rotate. Bevel gear one then drives the mixing shaft and mixing blades to rotate in turn. The mixing blades adopt a staggered multi-blade design and are distributed at different angles, which can form stronger convection in the vertical direction, accelerate fertilizer dissolution, and avoid excessively high local concentrations.

[0019] S3, Drip Irrigation Stage; Then, the fertilizer pump is started, and the mixed fertilizer solution is sequentially delivered through the irrigation water pipe and drip irrigation tape, and finally precisely delivered to the area around the walnut tree roots through the drippers, realizing integrated water and fertilizer drip irrigation for the walnut trees.

[0021] 1. This precision drip irrigation equipment for walnut trees integrates water and fertilizer. Through the coordinated operation of the stirring shaft, stirring blades, conical gear one and conical gear two, it can quickly and evenly mix fertilizer solution, prevent sedimentation, and ensure nutrient consistency. Thus, it can accurately adjust the irrigation water volume and fertilizer concentration in real time according to the water and fertilizer requirements of walnut trees at different growth stages.

[0022] 2. This precision drip irrigation equipment for walnut trees integrates water and fertilizer. Through the coordinated operation of the T-shaped rotating rod, rotating rod, push rod, and cleaning plate, it can regularly clean the impurities on the filter screen, preventing impurities from accumulating on the filter screen and affecting the subsequent liquid intake effect. The filter screen uses multi-layered stainless steel wire mesh with gradually changing pore size, which effectively intercepts impurities, extends the service life of the equipment, and maintains stable drip irrigation performance. The equipment has low integration and is easy to operate, with a low threshold for farmers to use, making it suitable for large-scale promotion and application.

[0023] 3. This precision drip irrigation system for walnut trees, integrating water and fertilizer, utilizes the coordinated operation of clamps, rotating components, fixing rods, and adjusting rods to ensure the drippers remain stable under varying terrain conditions.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] In one implementation, refer to Figures 1-9A precision drip irrigation device for walnut trees, integrating water and fertilizer, includes a storage tank 1, and further includes: a fertilizer pump 21 fixed at the bottom of the storage tank 1, the inlet of the fertilizer pump 21 being connected to the inside of the storage tank 1, and an irrigation water pipe 2 fixedly connected to the output end of the fertilizer pump 21, one end of the irrigation water pipe 2 being connected to a drip irrigation belt 3, with multiple drippers 4 spaced apart on the drip irrigation belt 3, each dripper 4 being positioned around the roots of the walnut tree; a feed hopper 5 fixed at the top of the storage tank 1, with a filter screen 51 inside the feed hopper 5 for filtering impurities in the fertilizer solution; a stirring mechanism 6 located inside the storage tank 1 for stirring the fertilizer solution to ensure uniform mixing; and an adjusting mechanism 8 installed on the surface of the drip irrigation belt 3 for supporting the multiple drippers 4.

[0038] In practice, a certain amount of fertilizer and an appropriate amount of water are first added to the storage tank 1 through the feed hopper 5, and the stirring mechanism 6 is started to fully dissolve and mix the fertilizer to form a fertilizer solution. The fertilizer pump 21 is responsible for pressurizing and sending the treated fertilizer solution into the irrigation water pipe 2, and then into the drip irrigation tape 3 through the branch pipe. The drip irrigation tape 3 is made of flexible material and is easy to lay. The drippers 4 on it are precisely designed to ensure uniform water output, and the spacing can be flexibly adjusted according to the size of the walnut tree crown and the density of the root system to ensure that each walnut tree receives an appropriate amount of water and fertilizer. The adjustment mechanism 8 is used to support the drip irrigation tape 3 and the drippers 4 to ensure that the drippers 4 can stably drip into the roots of the walnut tree.

[0039] In addition, the device can also be equipped with sensor and controller components. The sensor components can integrate soil moisture sensor, nutrient concentration sensor and flow monitoring module. The controller uses PID algorithm to achieve precise control and transmits data to the controller. The controller compares the received soil moisture and nutrient concentration data with preset thresholds. If the soil moisture is lower than the lower limit or the nutrient concentration is insufficient, the fertilizer pump 21 is started.

[0040] In one implementation, refer to Figure 2 and Figure 9 The stirring mechanism 6 includes a stirring shaft 61 that rotates inside the storage tank 1 via bearings. Several stirring blades 62 are fixedly connected to the surface of the stirring shaft 61. The stirring blades 62 are symmetrically arranged along the center line of the stirring shaft 61. A bevel gear 63 is fixedly connected to one end of the stirring shaft 61. A bevel gear 64 is meshed with the surface of the bevel gear 63. The bevel gear 64 is fixedly connected to the output shaft of the fertilizer pump 21. A protective shell 65 is fixedly connected to the bottom of the storage tank 1. The protective shell 65 is fitted onto the surface of the stirring shaft 61 and the stirring blades 62.

[0041] With this design, the stirring shaft 61 drives the stirring blades 62 to rotate. The unique staggered paddle blade design and reasonable layout can quickly and evenly mix the fertilizer solution, prevent sedimentation, and ensure nutrient consistency.

[0042] In actual operation, the rotation of the stirring shaft 61 can synchronously drive several stirring blades 62 to rotate. During the rotation of the stirring blades 62, they will agitate the solution inside the storage tank 1, thereby ensuring thorough mixing of the fertilizer solution. The stirring blades 62 are designed in a staggered pattern, with multiple blades at different angles. Compared with the traditional straight blade type, this design can create stronger convection in the vertical direction, accelerating fertilizer dissolution and preventing excessively high local concentrations. With the meshing of the bevel gear 1 63 and bevel gear 2 64 at the end of the stirring shaft 61, the fertilizer pump 21 can synchronously drive the bevel gear 2 64, bevel gear 1 63, and stirring shaft 61 to rotate. Synchronous rotation can reduce equipment resonance and lower equipment costs. In addition, the protective shell 65 ensures that the bevel gear 1 63 and bevel gear 2 64 are in a dust-free state, thereby reducing pollution.

[0043] In one implementation, refer to Figure 2 , Figure 3 and Figure 8 A linkage mechanism 7 is provided on the top of the storage tank 1. The linkage mechanism 7 is used to clean the impurities intercepted on the filter screen 51. The linkage mechanism 7 includes a T-shaped rotating rod 71 that rotates on the top of the storage tank 1 via a bearing. One end of the T-shaped rotating rod 71 is inserted into the inside of the stirring shaft 61. A rotating rod 72 is rotatably provided on the surface of the T-shaped rotating rod 71. A push rod 73 is rotatably connected to the end of the rotating rod 72 via a rotating shaft. The end of the push rod 73 passes through the feed hopper 5 and is fixedly connected to a cleaning plate 74. The cleaning plate 74 is attached to the surface of the filter screen 51. A baffle 52 is rotatably connected to one side of the feed hopper 5 via a rotating shaft. A through groove is opened on one side of the feed hopper 5. The baffle 52 is used to seal one side of the through groove. A torsion spring 53 is provided on one side of the baffle 52. The end of the torsion spring 53 is fixedly connected to the side of the feed hopper 5.

[0044] With this solution, the T-shaped rotating rod 71 can be used to periodically clean the impurities on the filter screen 51, preventing impurities from accumulating on the filter screen 51 and affecting the subsequent liquid inlet effect. The filter screen 51 uses a multi-layered stainless steel wire mesh with gradually changing pore size, which effectively intercepts impurities, prevents clogging of the dripper head 4, extends the service life of the equipment, and maintains stable drip irrigation performance.

[0045] In actual operation, with the linkage mechanism 7 in place, after the top of the T-shaped rotating rod 71 is inserted into the stirring shaft 61, the stirring shaft 61 can synchronously drive the T-shaped rotating rod 71 to rotate. When the T-shaped rotating rod 71 rotates, it can synchronously drive the rotating rod 72 and the push rod 73 to reciprocate linearly. The reciprocating motion of the push rod 73 drives the cleaning plate 74 to move linearly. Since the cleaning plate 74 is located above the filter screen 51, it can push the impurities filtered on the surface of the filter screen 51 to clean it, thereby ensuring the maximum filtration effect of the filter screen 51 and avoiding the inability to clean the impurities on the filter screen 51 in time, which would affect the subsequent filtration effect.

[0046] With the side baffle 52 of the feed hopper 5 in place, when the impurities cleaned from the surface of the filter screen 51 move, the impurities will push the baffle 52 open, so that the impurities will be discharged to the outside through the channel, thus avoiding the accumulation of impurities in the feed hopper 5 and affecting the subsequent liquid feeding efficiency.

[0047] With the torsion spring 53 on the side of the baffle 52, the baffle 52 can be automatically reset by the spring force of the torsion spring 53. At this time, the baffle 52 will automatically seal one side of the channel, thereby preventing the loss of liquid.

[0048] As a supplementary explanation, the bottom of the T-shaped rotating rod 71 is a rhomboid column, and the top of the stirring shaft 61 is provided with a matching rhomboid groove, thereby ensuring stable transmission of the T-shaped rotating rod 71.

[0049] In one implementation, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 The adjusting mechanism 8 includes a clamp 81 installed on the surface of the drip irrigation tape 3. A rotating component 82 is fixedly connected to the bottom of the clamp 81. Several fixed rods 83 are fixedly connected to the bottom of the rotating component 82. Adjusting rods 84 are sleeved on the surface of each of the fixed rods 83. The rotating component 82 includes a fixed disk 821 fixed to the bottom of the clamp 81. A rotating disk 822 is provided at the bottom of the fixed disk 821. A T-shaped annular groove 823 is opened inside the fixed disk 821. A T-shaped slider 824 is rotatably connected inside the T-shaped annular groove 823. The end of the T-shaped slider 824 is fixed to the top of the rotating disk 822. A torsion spring 53 is provided on one side of the baffle 52. The end of the torsion spring 53 is fixedly connected to the side of the feed hopper 5.

[0050] This design uses clamp 81 to restrict the position of rotating component 82, and uses fixing rod 83 and adjusting rod 84 to adjust the height of dripper 4. This ensures that dripper 4 remains stable under different terrain conditions, preventing it from shifting and causing water to flow inaccurately to the roots of crops.

[0051] In practice, the rotating part 82 at the bottom of the clamp 81 is first fitted onto the surface of the dripper 4, and then the clamps 81 are connected and fixed to each other with bolts. At this time, the fixing rod 83 and the adjusting rod 84 are located around the dripper 4. The adjusting rod 84 on the surface of the fixing rod 83 is adjusted to slide up and down, thereby inserting the adjusting rod 84 into the soil at different depths, so as to ensure that the dripper 4 can accurately drip water to the root of the walnut tree.

[0052] Furthermore, with the rotating component 82 in place, a fixed plate 821 can be connected to the bottom of the clamp 81, and a rotating plate 822 can be connected to the bottom of the fixed plate 821. Since the T-shaped slider 824 slides inside the T-shaped annular groove 823, and the T-shaped slider 824 is fixedly connected to the bottom of the rotating plate 822, the T-shaped slider 824 fits tightly against the bottom of the fixed plate 821 and can rotate circumferentially along the bottom of the fixed plate 821. By rotating the T-shaped slider 824, the positions of the fixed rod 83 and the adjusting rod 84 can be changed, thereby avoiding the roots of the walnut tree and preventing the adjusting rod 84 from failing to be firmly inserted into the soil for fixation.

[0053] In addition, there are three sets of fixed rods 83 and three sets of adjusting rods 84. Since the three sets have stable triangular support performance, the stability of the adjusting mechanism 8 is greatly guaranteed. The three sets of adjusting rods 84 are connected by a semi-ring, so when one adjusting rod 84 is adjusted, it can drive the other two sets of adjusting rods 84 to move at the same time. In addition, the surface of the adjusting rod 84 has a pin, which can be inserted into the pre-prepared hole on the surface of the fixed rod 83.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
