[0013] 1. This precision-proportioning water-soluble fertilizer dissolving and stirring device can simultaneously add different types of water-soluble fertilizers through three sets of equally spaced quantitative feeding mechanisms, eliminating the need for multiple feedings and achieving precise proportioning of multiple components. By starting the servo motor to drive the drive plate to rotate, the arc-shaped protrusion moves the protrusion on the baffle plate, causing the baffle plate to rotate, so that the leakage hole is precisely aligned or misaligned with the feeding hopper and the feeding pipe, accurately controlling the amount of fertilizer falling for each component, avoiding errors from manual proportioning, ensuring consistent water-fertilizer ratios, conforming to the fertilizer requirements of different crops, eliminating the need for manual feeding, and greatly improving proportioning efficiency.

[0014] 2. This precise proportioning water-soluble fertilizer dissolving and stirring device drives the stirring rod and four equally spaced V-shaped stirring blades to rotate by starting the stirring motor. The V-shaped structure increases the contact area with water and fertilizer, forming a vortex-like water flow, which can quickly break up fertilizer clumps, promote the full dissolution of fertilizer and water, and improve nutrient utilization. The filter plate on the right side of the mixing tank can intercept undissolved particles or impurities to avoid clogging the water outlet pipe and irrigation pipe. The brush plate at the right end of the stirring rod rotates synchronously with the stirring action to continuously clean the impurities on the surface of the filter plate, preventing the filter from clogging and causing poor water flow. No manual disassembly and cleaning is required, reducing the frequency of maintenance and labor intensity. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please refer to Figure 1-4One embodiment of this utility model is: a precise proportioning water-soluble fertilizer dissolving and stirring device, including a mixing tank 1. A water inlet with a sealed cap is opened on the outer wall of the mixing tank 1 for easy replenishment of clean water. A support frame 2 is connected to the outer wall of the mixing tank 1. A quantitative feeding mechanism is installed on the support frame 2. The quantitative feeding mechanism achieves precise quantity control, fundamentally solving the problems of time-consuming, labor-intensive, and inaccurate manual proportioning, ensuring accurate water-fertilizer ratios and avoiding impact on plant growth. The quantitative feeding mechanism includes: a mixing hopper 3 and a feeding pipe 4. The mixing hopper 3 is connected to the support frame 2 via a bracket. At the top of the support frame 2, a mixing hopper 3 stores water-soluble fertilizer. The mixing hopper 3 is a stainless steel funnel-shaped structure with a smooth inner wall to reduce fertilizer residue. A discharge pipe 4 is connected to the outer wall of the mixing tank 1. The top of the discharge pipe 4 passes through the support frame 2 and extends upwards, guiding the material to the mixing tank 1 in a directional manner. The quantitative dispensing mechanism also includes a rotating rod 5, which is rotatably connected to the top of the support frame 2 via bearings. A baffle plate 6 is connected to the top of the rotating rod 5. The top of the baffle plate 6 is in contact with the bottom of the mixing hopper 3, and the bottom of the baffle plate 6 is in contact with the top of the discharge pipe 4. The top of the material plate 6 has two material leakage holes 7 facing each other, and the rear material leakage hole 7 is connected to the feeding hopper 3 and the discharge pipe 4. The top of the baffle plate 6 is circumferentially connected with several protruding rods 8 at equal intervals. The top of the support frame 2 is connected to a servo motor 9, and the output end of the servo motor 9 is connected to a rotating shaft 10. The top of the rotating shaft 10 is connected to a drive plate 11. The outer wall of the drive plate 11 is integrally formed with arc-shaped protrusions, and the arc-shaped protrusions are arranged between two adjacent protruding rods 8. The servo motor 9 is electrically connected to an external PLC controller for easy control. The model used is a Panasonic MSMF042L1U2M servo motor. After receiving the pulse signal from the PLC, the motor rotor rotates at a preset angle and speed, driving the drive plate 11 to rotate. The arc-shaped protrusion of the drive plate 11 pushes the protruding rod 8, which drives the baffle plate 6 and the rotating rod 5 to rotate, so that the material leakage hole 7 on the baffle plate 6 is aligned or misaligned with the opening of the mixing hopper 3 and the discharge pipe 4. By controlling the opening and closing time and frequency, the amount of fertilizer falling is precisely controlled. Compared with manual feeding, the quantitative accuracy is greatly improved, ensuring that the water and fertilizer ratio is consistent for each batch.

[0019] There are three sets of quantitative feeding mechanisms, which are equally spaced on the support frame 2. These three equally spaced quantitative feeding mechanisms can add different types of water-soluble fertilizers or additives at the same time without the need for multiple feedings. This achieves precise multi-component ratios, adapts to the complex nutrient requirements of plants, and each mechanism can independently control the feeding amount. It can flexibly adjust the ratio of each fertilizer according to the soil nutrient content and crop needs. Compared with a single feeding mechanism, it is more versatile and adaptable to diverse planting scenarios.

[0020] Please refer to Figure 1-4Based on the above embodiments, in another embodiment of this utility model, a stirring mechanism is provided on the mixing tank 1. The stirring mechanism includes a stirring rod 12, which is rotatably connected to the inner left side of the mixing tank 1 via a bearing. A stirring motor 14 is connected to the left side of the mixing tank 1. The left end of the stirring rod 12 passes through the mixing tank 1 and is connected to the output end of the stirring motor 14. The stirring motor 14 is electrically connected to an external PLC controller for easy control. The model used is a Y90S-4 three-phase asynchronous motor. When working, the motor stator generates a rotating magnetic field after being supplied with three-phase AC power, which drives the rotor to rotate and drives the stirring rod 12 to rotate. The stirring motor 14 provides stable automatic power to the stirring rod 12, eliminating the need for manual stirring, especially... Suitable for long-term, large-volume mixing scenarios, significantly improving work efficiency and reducing manpower input; the outer wall of the mixing rod 12 is connected to the mixing blades 13, which are arranged in a "V" shape. There are four mixing blades 13, which are equidistantly connected to the outer wall of the mixing rod 12. The evenly distributed mixing blades 13 can disperse the force during mixing, prevent the mixing rod 12 from deforming due to excessive local force, and reduce the vibration of the mixing tank 1, thus extending the service life of the equipment; the rotation of the mixing rod 12 drives the mixing blades 13 to rotate. The structural design of the "V" shaped mixing blades 13 can increase the contact area with water and fertilizer, and at the same time form a vortex-like water flow, which can break up fertilizer clumps more quickly, promote the full dissolution of fertilizer and water, and improve nutrient utilization.

[0021] A water outlet pipe 15 is connected to the right side of the mixing tank 1. A solenoid valve is installed on the water outlet pipe 15 to control the water flow. The solenoid valve is electrically connected to an external PLC controller for easy control. After receiving an electrical signal from the PLC, the solenoid coil is energized to generate a suction force, which drives the valve core to move and open the water outlet pipe 15. After power is cut off, the valve core is reset under the action of the spring, closing the channel, thus realizing automatic control of water and fertilizer discharge. A filter screen plate 16 is connected to the inner wall of the right side of the mixing tank 1. The filter screen plate 16 is located at the water inlet of the water outlet pipe 15. The filter screen plate 16 is made of stainless steel woven mesh. The filter screen plate 16 can intercept undissolved fertilizer particles or impurities, preventing blockage of the water outlet pipe 15 or irrigation pipes, ensuring smooth water and fertilizer delivery, and is especially suitable for precision irrigation methods such as drip irrigation.

[0022] A brush plate 17 is connected to the right end of the stirring rod 12. The bristles of the brush plate 17 abut against the surface of the filter screen plate 16. The stirring rod 12 rotates to drive the brush plate 17 to rotate synchronously. The bristles continuously clean the impurities and undissolved particles on the surface of the filter screen plate 16, avoiding poor water flow caused by filter screen blockage. No manual disassembly and cleaning is required, reducing the frequency of maintenance.

[0023] The working principle of this utility model is as follows: In the quantitative feeding stage, three sets of equally spaced quantitative feeding mechanisms can simultaneously add different types of water-soluble fertilizers without the need for multiple feedings; by starting the servo motor 9, its output end drives the rotating shaft 10 and the top drive plate 11 to rotate. The arc-shaped protrusion on the outer wall of the drive plate 11 pushes the protruding rod 8 on the top of the baffle plate 6, causing the baffle plate 6 and the rotating rod 5 to rotate. When the leakage hole 7 on the baffle plate 6 is aligned with the bottom of the mixing hopper 3 and the top of the feeding pipe 4, the fertilizer falls into the mixing tank 1 through the leakage hole 7 and the feeding pipe 4; when the leakage hole 7 is misaligned with the mixing hopper 3 and the feeding pipe 4, the feeding stops. By controlling the rotation speed of the servo motor 9, the amount of fertilizer falling in each batch can be precisely controlled, avoiding manual mixing errors, ensuring a consistent water-fertilizer ratio, conforming to the fertilizer requirements of different crops, and eliminating the need for manual supervision; In the stirring and dissolving stage, the stirring motor is started. 14. Its output end drives the stirring rod 12 to rotate. The four V-shaped stirring blades 13, which are evenly distributed in a circle on the outer wall of the stirring rod 12, rotate synchronously. The V-shaped structure increases the contact area with water and fertilizer, which can form a vortex-like water flow, quickly break up fertilizer clumps, promote the full dissolution of fertilizer and water, and improve nutrient utilization. In the filtration and anti-clogging stage, the mixed water and fertilizer flow to the right side of the mixing tank 1. The filter screen 16 on the inner wall intercepts undissolved particles or impurities to avoid clogging the water outlet pipe 15 and subsequent irrigation pipes. At the same time, the brush plate 17 at the right end of the stirring rod 12 rotates synchronously with the stirring action. Its bristles abut against the surface of the filter screen 16 to continuously clean the impurities on the filter screen 16 and prevent the filter screen from clogging and causing poor water flow. No manual disassembly and cleaning is required, reducing maintenance costs. Finally, the water and fertilizer that meet the requirements are discharged through the opening of the water outlet pipe 15 by activating the solenoid valve for irrigation.
