Description

Technical Field

[0001] This utility model relates to the field of automatic fertilization drip irrigation technology, and in particular to an automatic fertilization drip irrigation device. Background Technology

[0002] In modern agricultural production, drip irrigation technology has become a widely used irrigation method due to its water-saving and high-efficiency characteristics. Traditional fixed drip irrigation systems usually require the pre-laying of pipelines. When transferring the system to different plots, the pipelines need to be re-laid, which not only consumes a lot of manpower and resources, but also takes a long time, seriously affecting the efficiency and timeliness of irrigation and fertilization, and making it difficult to meet the needs of modern agriculture for fast and efficient operations. Furthermore, the uniformity of fertilizer and water mixing during drip irrigation directly affects crop growth. Traditional equipment often lacks effective mixing devices, resulting in incomplete fertilizer and water integration. This prevents crops from absorbing nutrients evenly, thus impacting crop yield and quality. Simultaneously, impurities in the water source can easily clog drip irrigation nozzles. Existing drip irrigation equipment is not adequately designed for filtration and anti-clogging, making filter cleaning and maintenance inconvenient. Once clogging occurs, it not only reduces irrigation efficiency but can also damage crop growth. Moreover, traditional drip irrigation equipment has shortcomings in flow control, making it difficult to precisely adjust irrigation and fertilization amounts according to the needs of different crops and different growth stages.

[0003] Therefore, there is a need for an automatic fertilization drip irrigation system that can quickly transfer fertilizer, effectively filter impurities, fully mix fertilizer and water, and is easy to maintain. This is of great practical significance for improving agricultural production efficiency, reducing production costs, and ensuring good crop growth. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an automatic fertilization drip irrigation device that can solve the problems of automatic fertilization drip irrigation that cannot be quickly transferred, equipment blockage, incomplete mixing of fertilizer and water, and inconvenience in maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic fertilization drip irrigation device, comprising a cylindrical box, a support rod, a motor, a filter assembly, a stirring assembly, and a drip irrigation assembly, wherein the support rod is disposed at the lower end of the cylindrical box, and the motor is disposed at the upper end of the cylindrical box; An L-shaped pipe is fixedly connected to the bottom of the outer side of the cylindrical box, a drip irrigation assembly is fixedly connected to the left end of the L-shaped pipe, a connecting pipe is fixedly connected to one side of the cylindrical box, and the cylindrical box is fixedly connected to the filter assembly through the connecting pipe. A stirring assembly is installed inside the cylindrical box; The filter assembly includes an outer casing, an inlet pipe, and a filter block.

The stirring assembly includes an inclined fan blade assembly and a rotating shaft, with the fan blade assembly fixedly connected to the outer wall of the rotating shaft; the drip irrigation assembly includes a drip irrigation nozzle and a horizontal pipe, with the drip irrigation nozzle fixedly installed at the lower end of the horizontal pipe.

[0006] Preferably, the support rod is fixedly connected to the caster wheel disposed thereunder.

[0007] Preferably, an electrically controlled valve is fixedly installed on the outer wall of the L-shaped pipe.

[0008] Preferably, the drip irrigation nozzle is fitted with a sleeve, and a filter screen is fixedly installed inside the sleeve.

[0009] Preferably, the filter block is fixedly connected to two opposite sides, the filter block is fixedly connected to a lifting rod at the top, the outer box has two opposite inner walls with sliding grooves, the fixed blocks are slidably connected in the sliding grooves, and the outer box is fixedly connected to the cover set thereon by screws.

[0010] Preferably, the rotating shaft is fixedly connected to the output end of the motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) In terms of equipment movement, the automatic fertilization drip irrigation equipment can be moved across plots within 10 minutes by setting universal wheels at the lower end of the support rod. This completely changes the cumbersome operation of traditional fixed drip irrigation systems that require re-laying pipelines, greatly saves manpower and time costs, significantly improves the equipment's flexibility and operational efficiency, and can quickly respond to the irrigation and fertilization needs of different plots.

[0012] (2) In the fertilizer mixing stage, the inclined fan blade group connected by the rotating shaft of the automatic fertilization drip irrigation equipment, driven by the motor, can fully mix and blend the fertilizer and water by using the unique tilt angle and rotation power. Compared with the traditional equipment that lacks an effective mixing device, it ensures that the crops can absorb nutrients evenly, providing good nutritional conditions for crop growth and helping to improve crop yield and quality.

[0013] (3) In terms of impurity filtration and drip irrigation maintenance, the filter block of the filter component is designed with a lifting rod and a sliding groove, which is convenient for disassembly and cleaning and can effectively intercept large particles of impurities. The filter screen installed in the sleeve of the drip irrigation nozzle is also easy to disassemble and clean, further preventing fine particles from clogging the drip irrigation nozzle. Compared with the existing equipment, which has imperfect filtration and anti-clogging design and inconvenient filter screen maintenance, this device greatly reduces the risk of clogging of the drip irrigation system, ensures irrigation efficiency, and reduces the adverse effects on crop growth.

[0014] (4) In terms of flow control, the electric control valve installed on the outer wall of the L-shaped pipe can accurately control the speed and drip volume of the mixed fertilizer liquid, overcoming the shortcomings of insufficient flow control of traditional drip irrigation equipment. It can be flexibly adjusted according to the needs of different crops and different growth stages to achieve precise irrigation and fertilization, improve the utilization rate of water resources and fertilizers, and reduce production costs.

[0017] Please see Figures 1-4 This utility model provides a technical solution: an automatic fertilization drip irrigation device, including a support rod 2, a motor 301 and a cylindrical box 1. The support rod 2 is connected to the lower end of the cylindrical box 1, the motor 301 is connected to the upper end of the cylindrical box 1, an L-shaped pipe 6 is fixedly connected to the bottom of the outer side of the cylindrical box 1, a drip irrigation component is fixedly connected to the left end of the L-shaped pipe 6, a connecting pipe 401 is fixedly connected to one side of the cylindrical box 1, the cylindrical box 1 is fixedly connected to a filter component located on one side of the connecting pipe 401, and a stirring component is provided inside the cylindrical box 1. The filter assembly includes an outer casing 402, an inlet pipe 403, and a filter block 404. The inlet pipe 403 is fixedly connected to one side of the outer casing 402, and the filter block 404 is movably connected inside the outer casing 402. The stirring assembly includes an inclined fan blade assembly 302 and a rotating shaft 303, with the fan blade assembly 302 fixedly connected to the outer wall of the rotating shaft 303; The drip irrigation assembly includes a drip irrigation nozzle 304 and a horizontal pipe 3, with the drip irrigation nozzle 304 fixedly installed at the lower end of the horizontal pipe 3; The support rod 2 is fixedly connected to the caster 5 installed below it. The equipment can be moved across plots within 10 minutes by pushing the caster 5, avoiding the time and effort required to re-lay the pipeline network of the traditional fixed drip irrigation system. An electric control valve 4 is fixedly installed on the outer wall of the L-shaped pipe 6 to control the speed of the mixed fertilizer liquid and drip irrigation. A sleeve 305 is fitted on the drip irrigation nozzle 304. A filter screen 306 is fixedly installed inside the sleeve 305 to prevent fine particles from clogging. The sleeve 305 allows the filter screen 306 to be disassembled and cleaned by hand. The filter block 404 is fixedly connected to the two opposite sides of the filter block 409, and the filter block 404 is fixedly connected to the upper end of the filter block 404 to intercept large particles of impurities when water enters. The outer box 402 has two opposite inner walls with sliding grooves 408, and the fixed blocks 409 are slidably connected in the sliding grooves 408. The outer box 402 is fixedly connected to the cover 406 set on it by screws 407, which makes it easy to observe the condition of the filter block 404 and disassemble and clean it by hand. The rotating shaft 303 is fixedly connected to the output end of the motor 301. Because the rotating shaft 303 is connected to an inclined fan blade assembly 302, it can fully mix fertilizer and water.

[0018] Working principle: Water flows into the outer casing 402 of the filter assembly through the inlet pipe 403. The fixing blocks 409 on both sides of the filter block 404 slide along the slide groove 408, cooperating with the lifting rod 405 to intercept large particles of impurities and facilitate disassembly and cleaning. The water after preliminary filtration enters the cylindrical box 1 through the connecting pipe 401. Inside the cylindrical box 1, the motor 301 drives the rotating shaft 303 and the inclined fan blade assembly 302 to rotate, using centrifugal force and thrust to fully mix the fertilizer and water into a mixed liquid. The mixed liquid is transported through the L-shaped pipe 6 at the bottom of the outer side of the cylindrical box 1. The electronically controlled valve 4 on the L-shaped pipe 6 precisely controls the flow rate. The liquid flows into the horizontal pipe 3 of the drip irrigation assembly, and then drips onto the farmland through the drip irrigation nozzle 304. The filter screen 306 inside the sleeve 305 of the drip irrigation nozzle 304 can intercept fine particles, and the sleeve 305 is easy to disassemble and clean. In addition, the equipment can be moved across plots within 10 minutes via the casters 5 at the lower end of the support rod 2, avoiding the need to re-lay pipelines and improving efficiency and flexibility.

[0019] To further improve the disclosed content of the technical solution and enable those skilled in the art to fully understand the structural details, material selection, performance parameters, and operating mechanism of the automatic fertilization drip irrigation equipment, the following supplementary explanations are provided: I. Main Structure and Basic Parameters: 1. Design of cylindrical box 1 and support rod 2: The cylindrical tank is made of food-grade PE material (600mm diameter, 1200mm height, 8mm wall thickness), integrally molded using rotational molding (seamless, impact strength ≥25kJ / m²). The outer wall of the tank features volume markings (one graduation every 100L) for easy observation of the mixed liquid volume. The top of the tank has a flange structure (650mm diameter), connected to the motor mounting plate with eight M12 bolts. A nitrile rubber sealing ring (5mm thickness) is installed on the flange face, with an IP66 sealing rating to prevent rainwater ingress. The inner wall of the tank is smooth (roughness Ra0.8μm), and the bottom has a tapered design (30° cone angle) to facilitate complete liquid drainage (residual amount ≤5L).

[0020] The support rods are galvanized seamless steel pipes (50mm diameter, 3.5mm wall thickness, 800mm height), totaling four rods, arranged in an equilateral triangle at the bottom of the cylindrical box (300mm spacing), and connected to the bottom of the box body via flanges (4 M10 bolts, preload 25N·m). A 10mm thick steel plate (150mm×150mm) is welded to the bottom of each support rod as a mounting base, and fixed to casters with bolts. The overall load-bearing capacity is ≥500kg, and the verticality error is ≤1mm / m.

The wheel core is made of cast iron (hardness 180-220HB), and the bearing model is 6204 (rated dynamic load 14.1kN). The casters are equipped with a dual braking system (wheel brake + directional brake), with a braking force of ≥500N, ensuring no slippage when the equipment is parked. The overall weight of the equipment is 300kg. The traction force is ≤50N when moving on cement ground and ≤100N when moving on field dirt roads (slope ≤5°), meeting the requirement of transferring between plots (distance 500m) within 10 minutes.

[0022] II. Filtration Components and Water System: 1. Design of outer casing 402 and filter block 404: The outer casing is welded from 304 stainless steel (dimensions 500mm×300mm×400mm, wall thickness 3mm), and the inner wall is electrolytically polished (roughness Ra0.4μm). The bottom slopes towards the connecting pipe 401 (slope 5°) for easy drainage. The top of the outer casing is open (dimensions 400mm×250mm) and sealed with a 406 cover (cover material 304 stainless steel, thickness 5mm). A silicone sealing ring (section 6mm×6mm) is installed between the cover and the casing, and it is secured with four M8 screws 407 (preload 15N・m). The screws are treated with an anti-corrosion coating (salt spray test ≥500 hours).

[0023] The filter block 404 is a composite filter media structure (350mm×200mm×150mm), consisting of three layers: an outer layer of stainless steel perforated mesh (2mm pore size, 304 material), a middle layer of PP melt-blown filter element (50μm pore size), and an inner layer of activated carbon fiber (for adsorbing organic matter). It has a filtration accuracy of 50μm and a retention efficiency of ≥98% (for impurities with a particle size ≥50μm). The fixing blocks 409 on both sides of the filter block are made of ABS material (30mm×30mm×20mm), with a 1-2mm gap fitting with the sliding groove 408 (32mm×32mm×350mm) on the inner wall of the outer casing to ensure smooth pulling (pulling resistance ≤10N). The lifting rod 405 at the top of the filter block is made of 304 stainless steel (12mm diameter, 200mm length), with a non-slip rubber sleeve (Shore hardness 60A) for easy gripping and disassembly.

[0024] 2. Performance parameters of inlet pipe 403 and connecting pipe 401: The inlet pipe is a DN50 PVC-U pipe (4.6mm wall thickness, working pressure 1.6MPa). One end is connected to the side of the outer casing (50mm from the bottom) via a flange, and the other end is connected to the water source (such as the water pump outlet). A pressure gauge (range 0-1MPa, accuracy ±1.6%) and a manual gate valve (model Z45T-10) are installed on the pipe. The inlet pipe flow rate is designed to be 5-15m³ / h (adjustable via the gate valve).

[0025] The connecting pipe is a DN40 304 stainless steel corrugated pipe (1000mm in length, 20mm in corrugation spacing), with both ends threaded to the outer casing and the cylindrical casing (sealed with PTFE tape). It can withstand an angular deviation of ±30°, facilitating pipeline compensation during equipment movement. The connecting pipe has a working pressure of 1.0MPa and a burst pressure of 3.0MPa.

[0026] III. Core parameters of the mixing system: 1. Design of motor 301 and shaft 303: The motor is a three-phase asynchronous motor (model Y90S-4, power 1.1kW, voltage 380V, speed 1440rpm), with an IP55 protection rating, F-class insulation, and operating noise ≤75dB (at a distance of 1m). The motor is fixed to the center of the top of the cylindrical box via a motor mount (material HT200 cast iron). The motor mount is connected to the box flange by eight M12 bolts (preload force 30N・m). A flexible coupling (model HL24, allowable torque 25N・m) is installed between the motor output shaft and the rotating shaft to compensate for installation errors (radial ≤0.1mm, axial ≤0.5mm).

[0027] The shaft is made of 45# steel with heat treatment (diameter 40mm, length 1000mm), chrome-plated (thickness 20μm), and has a straightness error ≤0.1mm / m. The lower end of the shaft is mounted on the bearing housing at the bottom of the cylindrical box (material 304 stainless steel) via a deep groove ball bearing (model 6308, rated dynamic load 29.8kN). A mechanical seal (model MG1-40, sealing surface material SiC to SiC) is used between the bearing housing and the box to prevent liquid leakage (leakage ≤3 drops / h).

[0028] 2. Performance parameters of fan blade assembly 302: The fan blade assembly consists of three inclined blades (made of 304 stainless steel, 3mm thick), each measuring 400mm × 150mm. The angle between the blade and the axis of rotation is 30° (helix angle), and the distance between the blade edge and the inner wall of the cylindrical box is 15-20mm (to avoid friction). The fan blades and the shaft are fully welded (weld leg height 4mm), and stress relief treatment is performed after welding (heat preservation at 200℃ for 2 hours). During stirring, the fan blade assembly generates strong axial and radial flow (liquid circulation rate ≥20m³ / h), ensuring a fertilizer-water mixing uniformity ≥95% (sampling test, nutrient concentration deviation ≤5%). The fan blades undergo dynamic balancing testing (imbalance ≤15g・mm), and the amplitude during operation is ≤0.1mm.

[0029] IV. Drip Irrigation Components and Flow Control: 1. Design of horizontal pipe 3 and drip irrigation nozzle 304: The horizontal pipe is a DN32 PE pipe (3.0mm wall thickness, 0.6MPa working pressure), 3000mm in length, and is fixed to the support rod extension bracket (the bracket is 500mm above the ground) with pipe clamps. Drip irrigation nozzles are evenly distributed along the length of the horizontal pipe (6 nozzles, 500mm apart), and the nozzles are connected to the horizontal pipe by threads (O-rings are used for sealing).

[0030] The drip irrigation nozzle is a turbulent flow type (ABS material, flow rate adjustable from 2-8L / h), with a nozzle outlet diameter of 2mm and an operating pressure of 0.1-0.3MPa. The nozzle is externally fitted with a 305 sleeve (PP material, inner diameter 15mm, length 50mm), inside which is installed a 306 filter screen (316L stainless steel, 100μm pore size). The filter screen is secured inside the sleeve with clips (removal / installation time ≤10 seconds), effectively intercepting fine particles (interception efficiency ≥90%). The sleeve and nozzle are interference-fitted (fitting tolerance H7 / g6), with a pull-in / pull-out force of 50-100N (for easy disassembly and cleaning).

[0031] 2. Performance of L-shaped pipe 6 and electrically controlled valve 4: The L-shaped pipe is a DN40 304 stainless steel pipe (3mm wall thickness), welded at one end to the bottom of the cylindrical box (50mm from the edge), and the other end connected to the horizontal pipe (equipped with EPDM rubber gasket) via a flange. An electrically controlled valve 4 (model Q941F-16, 304 stainless steel, DN40 diameter) is installed in the middle of the L-shaped pipe. The valve is equipped with an electric actuator (voltage 220V, switching time ≤5 seconds, protection level IP65), and its opening can be controlled by a PLC or remote control (0-100% stepless adjustment), with a flow control accuracy of ±2%. Pressure sensors (range 0-0.6MPa, accuracy ±0.5%) are installed before and after the valve to monitor the pipeline pressure in real time. When the pressure ≥0.4MPa, the valve automatically closes (to protect the drip irrigation system).

[0032] V. Automatic Operation Process and Control Logic: 1. Fertilization and irrigation control process: Preparation stage: Check that all parts are securely connected (especially pipe flanges and motor fixing bolts); open the outer cover 406, insert the filter block 404 into place along the slide groove 408, close the cover and tighten the screws; add solid fertilizer or liquid fertilizer (according to crop needs, such as nitrogen, phosphorus and potassium compound fertilizer) through the top opening of the cylindrical box, the amount added should not exceed 80% of the volume of the cylindrical box (400L).

[0033] Start-up phase: Open the manual gate valve of the inlet pipe, and the water source flows into the filter assembly through the inlet pipe. After being filtered by the filter block, it enters the cylindrical tank through the connecting pipe. When the liquid level in the cylindrical tank reaches 50% (600mm), start motor 301. The rotating shaft drives the fan blade assembly to rotate (the stirring time is set to 5-10 minutes) to fully mix the fertilizer and water (the concentration of the mixed solution can be adjusted by sampling and testing).

[0034] Drip irrigation stage: After mixing, open the electronically controlled valve 4 (initial opening 30%). The mixture is delivered to the drip irrigation nozzles through the L-shaped pipe and horizontal pipe, and evenly dripped to the crop roots. Adjust the valve opening with the remote control to control the drip irrigation flow rate (e.g., 5L / h for vegetable seedlings and 10L / h for fruiting). Set the drip irrigation time according to the crop irrigation needs (adjustable from 0 to 24 hours), and the valve will automatically close after the set time is reached.

[0035] Shutdown phase: Close the inlet gate valve, open the drain valve (DN20 diameter) at the bottom of the cylindrical tank to drain the residual liquid; disassemble the drip irrigation nozzle sleeve 305 and clean the filter screen 306; pull out the filter block 404, rinse it with clean water and reinstall it for the next use.

[0036] 1. Security protection mechanism: Overload protection: The motor is equipped with a thermal relay (set current 4.5A). When the mixing load is too large (such as fertilizer clumping) and the current exceeds the limit, the motor will automatically stop and issue an audible and visual alarm.

[0037] Clogging protection: When the drip irrigation nozzle filter becomes clogged, causing the pipeline pressure to be ≥0.4MPa, the pressure sensor triggers the protection mechanism, the electronically controlled valve automatically closes to 10% of its opening, and an alarm is issued to prompt the filter to be cleaned.

[0038] Liquid level protection: A liquid level sensor (ultrasonic model, measuring range 0-1200mm, accuracy ±1mm) is installed inside the cylindrical tank. When the liquid level is ≤100mm, stirring and drip irrigation will be stopped automatically to prevent the motor from running dry.

[0039] Leakage protection: The equipment is equipped with a 30mA / 0.1s leakage current protector, and the grounding resistance of all electrical components is ≤4Ω to ensure the safety of operators.

[0040] VI. Installation and Maintenance Requirements: 1. Equipment Installation Specifications: Site preparation: Select a flat site (slope ≤ 3°), remove stones and weeds from the ground, and lay a gravel layer (100mm thick) if necessary to ensure that the equipment is placed stably (levelness error ≤ 2mm / m).

[0041] Pipeline connection: After the inlet pipe is connected to the water source, a water pressure test is conducted (1.0MPa, pressure held for 30 minutes without leakage); when installing the drip irrigation horizontal pipe, keep it horizontal (straightness error ≤5mm / m), and the nozzle should be facing the crop roots (deviation ≤10°).

[0042] Electrical wiring: The power cords for the motor and electrically controlled valves are YJV-0.6 / 1kV-3×4mm² cables, which are buried in PVC pipes (50mm in diameter) (depth ≥500mm). The junction boxes are sealed (IP65) to prevent moisture.

[0043] 1. Regular maintenance items: Daily: Check the pressure difference before and after the filter block (≤0.1MPa, if it exceeds this, it needs to be cleaned); observe whether the water output from the drip irrigation nozzle is uniform (whether there is any blockage); record the motor operating temperature (≤65℃).

[0044] Weekly: Clean the drip irrigation nozzle filter screen (306) and filter block (404); check the fan blade assembly for looseness or deformation; calibrate the flow rate of the electronically controlled valve (compare with a flow meter).

[0045] Monthly: Add lithium-based grease (model GB7324-2010) to the motor bearings and caster wheel bearings, each time adding 1 / 3 of the bearing cavity volume; check the sealing of pipeline flanges (for leaks); test electrical protection functions (overload, leakage).

[0046] Quarterly: Replace mechanical seals (to prevent shaft leakage); check stainless steel components for corrosion (apply anti-rust paint); calibrate level and pressure sensors.

[0047] 1. Common faults and solutions: VII. Performance Comparison with Traditional Drip Irrigation Equipment: This device, through its integrated design of high-efficiency filtration, powerful mixing, precise control, and flexible mobility, solves the problems of difficult movement, uneven mixing, and easy clogging of traditional drip irrigation equipment. It is especially suitable for small and medium-sized farms (planting area of ​​50-500 mu), saving 40-60% of water, 30-50% of fertilizer, and reducing labor input by more than 70%, while increasing crop yield by 10-20%, with significant economic and ecological benefits.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
