[0035] The stirring assembly 10 includes a motor frame 4, a stirring motor 5, a diverter 6, a main rotating sleeve 21, a telescopic cylinder 22, a telescopic gas rod 25 and a magnetic disk 26.

[0036] The stirring assembly 10 also includes a rotating plate 23, a convex plate 24, a lower clamping plate 27 and an upper clamping plate 28. The rotating plate 23 is fixedly connected to the middle of the main rotating sleeve 21. The convex plate 24 and the middle of the rotating plate 23 are rotatably connected with a bearing. The upper clamping plate 28 is fixedly connected to the top of the magnetic disk 26, and the lower clamping plate 27 is fixedly connected to the bottom of the convex plate 24. When the magnetic disk 26 moves to the top, the lower clamping plate 27 abuts against the upper clamping plate 28, driving the convex plate 24 to rotate.

[0037] The coil sleeve 31 and the magnetic column 30 adopt a threaded sliding structure, and the relative height between the two is adjusted by rotation to achieve stepless adjustment of the magnetic field intensity from 0.1 to 1.2T.

[0038] The telescopic cylinder 22 allows the magnetic disk 26 to rise and fall quickly, adapting to the mixing needs of fertilizers with different viscosities and reducing energy consumption by 20%. The raised plate 24 rises and falls with the magnetic disk 26, periodically colliding with the lower and upper clamping plates 27 and 28, triggering the cleaning component 9 to clean the mixing chamber 7.

[0039] The cleaning assembly 9 includes a cleaning cover 11, a cleaning baffle 12, a cleaning inlet pipe 13, a cleaning main pipe 14, a cleaning branch pipe 15, a cleaning block 16, a cleaning spring 18, a cleaning baffle ring 17, a cleaning slide column 19 and a cleaning plug 20.

A torsion spring is provided at the connection between the cleaning cover 11 and the cleaning tank 8. When the cleaning baffle 12 is not subjected to external force, the cleaning cover 11 keeps the cleaning tank 8 closed. The cleaning main pipe 14 is installed on the side of the cleaning cover 11 close to the cleaning tank 8. A cleaning plug 20 is fixed to the top of the cleaning main pipe 14. A cleaning baffle 17 is provided on the top of the cleaning plug 20 and is fixed to the cleaning main pipe 14. The cleaning slide column 19 is connected to the cleaning main pipe 1 4 is slidably connected at the top, and the bottom of the cleaning slide post 19 is a conical structure. The bottom of the cleaning slide post 19 is inserted into the cleaning plug 20. The top of the cleaning slide post 19 is fixed with a cleaning block 16. The two ends of the cleaning spring 18 respectively abut on the cleaning baffle 17 and the cleaning block 16. A plurality of cleaning branches 15 with nozzles are fixed to one side of the cleaning main pipe 14. The convex plate 24 abuts on the cleaning baffle 12, pushing the cleaning cover 11 to flip open, and the cleaning block 16 is separated from the abutment of the cleaning groove 8. The cleaning slide post 19 is pushed upward by the cleaning spring 18, and the bottom of the cleaning slide post 19 is separated from the cleaning plug 20, so that the cleaning plug 20 is opened. The high-pressure cleaning spray in the cleaning branch pipe 15 enters the cleaning main pipe 14 and is then sprayed out through the cleaning branch pipe 15, periodically self-cleaning the impurities inside the mixing chamber 7.

[0040] The stirring motor 5 drives the main rotor 21 to rotate, driving the telescopic air rod 25 and magnetic disk 26 up and down. Combined with the magnetic column 30, coil sleeve 31, and stirring rod 34, magnetic field-assisted stirring is achieved. The cleaning spring 18 and cleaning slide 19 control the opening and closing of the cleaning branch 15, which automatically closes the cleaning tank 8 in conjunction with the cleaning baffle 12. During stirring, the cleaning assembly 9 uses fluid pressure to push open the cleaning slide 19, and high-pressure water is ejected from the cleaning branch 15 to flush the inner wall of the mixing chamber. During shutdown, the cleaning spring 18 automatically returns to close the cleaning tank 8 to prevent the ingress of impurities.

[0041] The mixing assembly 1 includes a mixing chamber 7, and the stirring assembly 10 also includes a disk baffle 29, a magnetic column 30, a coil sleeve 31, a suction plate 32, a suction plate slot 33, a stirring rod 34, a stirring rod block 35 and a slice 36. The disk baffle 29 is fixed to the bottom of the disk 26, the magnetic column 30 is fixed to the mixing chamber 7, the coil sleeve 31 is slidably connected to the outer wall of the magnetic column 30, the suction plate 32 is fixed to the top of the coil sleeve 31, the suction plate slot 33 is evenly arranged at intervals on the top of the suction plate 32, and the suction plate slot 33 is snapped with the disk baffle 29. A plurality of stirring rods 34 are evenly distributed and detachably connected to the outer wall of the coil sleeve 31 through the stirring rod block 35. A plurality of slices 36 are evenly distributed and detachably connected to the side of the stirring rod 34 away from the coil sleeve 31. A stirring plate 37 is fixed to the bottom of the coil sleeve 31.

[0042] Matching threaded grooves are located on the outer wall of the magnetic column 30 and the inner wall of the coil sleeve 31. The magnetic column 30 and coil sleeve 31 are threaded and slidingly connected, and an electromagnet is housed within the magnetic disk 26. The combined rotational and longitudinal shearing motion of the stirring rod 34 and the slicer 36 breaks fertilizer clumps down to the micron level, improving mixing uniformity by 40%. The stirring rod 34 is detachable via the stirring rod clamp 35, and the coil sleeve 31 is threadedly connected to the magnetic column 30, facilitating quick replacement of worn parts and reducing maintenance time by 50%.

[0043] The electromagnetic coupling design of the magnetic disk 26 and the magnetic column 30 changes the magnetic field strength by adjusting the thread sliding height of the coil sleeve 31, thereby enhancing the dispersion and dissolution efficiency of the fertilizer particles and reducing precipitation.

[0044] The spray assembly 3 includes a spray support block 45, a spray rotary sleeve 46, a spray rotary cylinder 47, a spray support plate 48, a spray support ring 49, a spray support 50, a spray rotary block 51, a nozzle 52 and a magnetic nozzle 53. The spray support block 45 is installed at one end of the transmission assembly 2. The spray rotary sleeve 46 is fixedly connected to the front end of the spray support block 45. The top of the spray support block 45 is fixedly connected to the spray support plate 48. The outer wall of the spray rotary cylinder 47 is fixedly connected to multiple spray supports 50. The spray rotary block 51 is rotatably connected to the spray support 50. The nozzle 52 is fixed to the spray rotary block 51. The magnetic nozzle 53 is slidably connected to the nozzle 52. Multiple spray support rings 49 are hinged at evenly spaced intervals on the top of the spray support plate 48, and the spray support rings 49 are clamped on the magnetic nozzle 53.

[0045] The magnetic nozzle 53 has a built-in electromagnetic coil that adjusts the current to vary the magnetic field strength by 0.1-1.5T. This enhances the ionic activity of the fertilizer solution under the magnetic field, increasing crop absorption by 25%. The spray rotor 51 supports 360° rotation, and the spray support ring 49 can lock the nozzle angle between 0-90° to adapt to different terrains and crop heights. The magnetic nozzle 53 uses a conical sealing structure, which automatically closes the nozzle hole through magnetic attraction when the machine is shut down to prevent residual droplets. Multiple nozzles 52 are arranged in a circular pattern, and magnetic field-assisted atomization keeps the droplet size within 50-200μm, achieving a spray coverage uniformity of 95%.

[0046] The transmission assembly 2 includes a feed port 38, a screw plate 39, and a transmission pipe 40. The feed port 38 is connected to the bottom of the mixing bin 7 and is fixed to the top of the transmission pipe 40. The screw plate 39 is rotatably connected to the inside of the transmission pipe 40. One end of the transmission pipe 40 is connected to the spray support block 45. A pressurized pipe 41 is installed at the bottom of the transmission pipe 40.

[0047] The spiral structure of the screw plate 39 evenly propels fertilizer to the spraying end, and the pressurized tube 41 provides real-time air pressure, ensuring a stable flow rate with a flow fluctuation of less than 5%. The inner wall of the transmission tube 40 is smooth and has no dead corners. The centrifugal force generated by the rotation of the screw plate 39 suspends the fertilizer particles and prevents sedimentation.

[0048] The transmission component 2 also includes a transmission motor 42, a transmission bracket 43 and a transmission belt 44. The transmission bracket 43 is fixed to one end of the transmission tube 40, the transmission motor 42 is fixed to the transmission bracket 43, and the transmission motor 42 is connected to the screw plate 39 through the transmission belt 44.

[0049] The transmission motor 42 adopts variable frequency control, which automatically adjusts the screw plate speed according to the flow demand, reducing energy consumption by 30%.

[0050] As shown in the drawings, there is provided a preferred embodiment of the present invention.

[0051] The working principle of the present invention is as follows:

[0052] Device startup and initialization

[0053] Power on: Turn on the main power lithium iron battery pack and solar auxiliary power supply system, and initialize the central controller ARMCortex-M7.

[0054] Parameter preloading: Fertilization parameters such as fertilizer type, spraying amount, and magnetic field strength range are input through the controller, and the AI ​​algorithm generates the initial control strategy.

[0055] Component reset: The magnetic disk 26 of the stirring component 10 rises to the initial high position, and the cleaning slide 19 of the cleaning component 9 resets to close the cleaning tank 8.

[0056] The magnetic nozzle 53 of the spray assembly 3 is closed by magnetic attraction, and the angle of the nozzle 52 is reset to the default position vertically downward.

[0057] Collaborative mechanism: The controller synchronously detects the flow, temperature, and humidity of each sensor to ensure that there are no abnormal alarms.

[0058] 2. Mixing stage

[0059] Feeding and premixing: Fertilizer raw materials are fed into the mixing bin 7 from the top, and the stirring motor 5 is started to drive the main rotor 21 to rotate at a low speed of 100 rpm. The stirring rod 34 and the slicer 36 initially crush the large particles.

[0060] Magnetic field enhanced stirring: the telescopic cylinder 22 pushes the magnetic disk 26 downward, the magnetic disk baffle 29 engages with the suction plate slot 33, and the coil sleeve 31 moves upward along the magnetic column 30 thread, and the magnetic field strength is increased to 0.8T.

[0061] The alternating magnetic field destroys the electrostatic agglomeration of fertilizer particles and enhances the ion activity of the solution.

[0062] Self-cleaning trigger: When the magnetic disk 26 rises to the highest point, the convex plate 24 collides with the lower clamping plate 27, lifting the cleaning slide 19, and the cleaning branch pipe 15 sprays high-pressure water to flush the inner wall of the mixing chamber.

[0063] Synergistic mechanism: The magnetic field strength is dynamically adjusted according to the viscosity of the fertilizer: when the viscosity is too high, the coil sleeve 31 automatically moves downward to reduce the magnetic field strength to avoid energy overload.

[0064] 3. Transmission phase

[0065] Valve opening: the stirring motor 5 reverses, the suction plate 32 separates from the magnetic disk baffle 29 , the valve at the bottom of the mixing bin 7 opens, and the fertilizer liquid flows into the transmission pipe 40 .

[0066] Dynamic pressure-stabilized delivery: The transmission motor 42 drives the screw plate 39 to rotate, pushing the fertilizer liquid to the spraying end. The flow rate is controlled by a frequency converter at 0.5-2.5 m / s. The pressurized pipe 41 replenishes air pressure based on feedback from the flow sensor, maintaining a stable pressure of 0.3-0.6 MPa.

[0067] Anti-sedimentation design: The centrifugal force on the inner wall of the transmission tube 40 suspends the fertilizer particles, and the screw plate 39 periodically rotates in the opposite direction once every 5 minutes to prevent sedimentation.

[0068] Synergy mechanism: The speed of the transmission belt 44 and the screw plate 39 are linked to ensure that the flow error is less than 3%.

[0069] 4. Spraying stage

[0070] Multi-channel adjustment:

[0071] The central controller sends instructions to the servo motor to drive the rack-gear set to adjust the opening of the magnetic nozzle 53, and at the same time, the magnetic field slider is linked to retract / expand to match the spraying mode of large flow focused magnetic field / small flow diffused magnetic field.

[0072] Magnetic field atomization spraying: The electromagnetic coil built into the magnetic nozzle 53 is energized at 0.5-1.2T. The fertilizer liquid is atomized into 50-200μm droplets under the action of the magnetic field, and the spraying support ring 49 locks the spray angle at 0-90°.

[0073] Real-time feedback adjustment: Spectral sensors detect crop canopy density and dynamically adjust the nozzle's 52-degree rotation angle. Soil moisture sensors provide feedback, and AI algorithms optimize single-channel flow distribution.

[0074] Synergistic mechanism: The magnetic field strength of the magnetic nozzle 53 is intelligently matched to the nozzle opening: at high flow rates, the magnetic field focuses to enhance ion polarization, while at low flow rates, the diffuse magnetic field prolongs the residence time.

[0075] 5. Self-cleaning and reset phase

[0076] Mixing bin cleaning: After the shutdown command is triggered, the stirring assembly 10 continues to run for 1 minute, the cleaning branch pipe 15 sprays water to flush the bin wall, and the residual liquid is discharged through the transmission pipe 40.

[0077] Pipeline emptying: The transmission motor 42 drives the screw plate 39 to rotate in the opposite direction to empty the residual liquid in the transmission pipe 40; the magnetic nozzle 53 is magnetically closed to prevent dripping.

[0078] Component reset: the magnetic disk 26 is raised to the high position, the coil sleeve 31 is reset to the initial position; the spray support ring 49 is restored to the vertical angle.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
