Description

Technical Field

[0001] This utility model relates to the field of soil improvement technology, specifically to a water-retaining soil improvement fertilizer mixing device with moisture regulation. Background Technology

[0002] Soil quality is directly related to crop yield and quality. Due to long-term over-cultivation, unreasonable fertilization and environmental pollution, soil in many areas has experienced a series of degradation problems such as compaction, acidification, decline in organic matter and weakened water and fertilizer retention capacity.

[0003] Therefore, it is necessary to improve degraded soil, restore its granular structure, enhance its fertility and drought resistance. Soil improvement fertilizers, especially functional fertilizers that integrate nutrients, improve substrate and water-retaining components, have become an effective means to solve this problem.

[0004] In the production process of soil amendment fertilizers, it is crucial to ensure the improvement effect by uniformly mixing components such as base fertilizers, soil conditioners, and water-retaining agents.

[0005] Currently, existing mixing equipment, such as Chinese utility model patent publication number CN219664723U, discloses a mixing device for soil improvement. This device uses a vibrating grid to screen the soil to be improved, removing large stones, and uses an amendment distribution device to spread powdered amendment on the screened soil. Simultaneously, it employs negative pressure extraction and a spraying device to control dust. This equipment is used for the preliminary screening of materials and a simple combination of dry powder. However, the main shortcoming of the above-mentioned existing technical solutions is that the additive dosing system of the equipment is only designed for dry powder materials and cannot be adapted to and add liquid additives, which limits the application scope of the soil improvement equipment and cannot be used for high-end compound improvement fertilizers that combine liquid and solid.

[0006] Therefore, we propose a water-retaining soil amendment fertilizer mixing device with moisture regulation to solve the problems mentioned above. Utility Model Content

[0022] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0023] Example 1: Please see Figure 1-4 This utility model provides a technical solution: A water-retaining soil conditioner fertilizer mixing device with moisture regulation includes a mixing tank 1, which is horizontally positioned. A drive rod 2 is coaxially arranged inside the mixing tank 1, and a spiral blade 3 is installed on the drive rod 2. A drive motor 4 is installed at one end of the mixing tank 1. A humidity sensor 5 is installed inside the mixing tank 1, and an atomizing nozzle 6 is installed on the side wall of the mixing tank 1. A premixing mechanism is arranged above the mixing tank 1, which includes a feeding cylinder 8 and a crushing and mixing device disposed therein. Humidity sensor 5 and atomizing nozzle 6 are connected to the control system. The system dynamically adjusts the spray volume of atomizing nozzle 6 based on the real-time humidity value detected by humidity sensor 5, thereby achieving closed-loop control of moisture.

[0024] In the above scheme, inside the horizontally set mixing tank 1, the drive motor 4 drives the drive rod 2 and the spiral blade 3 to rotate, thereby realizing the mixing and axial conveying of the material; the humidity sensor 5 set in the mixing tank 1 detects the humidity of the material in real time and transmits the signal to the control system. The control system dynamically adjusts the spray volume of the side wall atomizing nozzle 6 according to the preset humidity value, thereby realizing precise closed-loop control of moisture and ensuring that the fertilizer reaches the optimal moisture content.

[0025] The mixing tank 1 has an opening at the end furthest from the drive motor 4, which is used to output the soil mixed with the improved fertilizer.

[0026] In the above scheme, after the mixing process is completed, the drive motor 4 continues to drive the spiral blade 3 to rotate, continuously pushing out the evenly mixed soil and improved fertilizer from the opening end, realizing the smooth discharge of materials and continuous operation, and improving the equipment processing efficiency.

[0027] A cover 11 is slidably connected to the open end of the mixing tank 1. The cover 11 is sleeved on the outside of the drive rod 2, and an electric push rod 12 is installed at the open end of the mixing tank 1. The electric push rod 12 pushes the cover 11 to slide, which is used to open and close the open end of the mixing tank 1.

[0028] In the above scheme, during the mixing process, the electric push rod 12 pushes the baffle 11 to close the opening, preventing material leakage and external contamination; when it is necessary to discharge, the electric push rod 12 pulls the baffle 11 to open the opening, so that the material can be smoothly output under the push of the spiral blade 3, thus realizing effective isolation and control of the mixing and discharging process.

[0029] A support mechanism is provided below the mixing tank 1. The support mechanism includes a U-shaped stabilizing seat 14, and the mixing tank 1 is fixedly installed inside the U-shaped stabilizing seat 14.

[0030] In the above scheme, the U-shaped stabilizer 14 wraps around and fixes the mixing tank 1, providing stable mechanical support, preventing the equipment from vibrating or displacing due to uneven force during the mixing process, ensuring the normal operation of the drive components, and extending the service life of the equipment.

[0031] A support platform 15 is provided below the U-shaped stabilizer 14. A baffle plate 16 is fixedly provided on the edge of the support platform 15. The bottom of the U-shaped stabilizer 14 slides in conjunction with the inside of the baffle plate 16. A pressure sensor 17 is installed between the U-shaped stabilizer 14 and the support platform 15.

[0032] In the above scheme, pressure sensor 17 monitors the total weight of mixing tank 1 and the materials inside in real time and uploads the data to the control system. The system determines the amount of material input or output status based on the weight change, and performs quantitative batching and process monitoring.

[0033] The upper part of the feeding cylinder 8 is fixedly connected to the mixing tank 1 near the drive motor 4, and the side of the feeding cylinder 8 is fixedly connected to the inclined feeding hopper 18.

[0034] In the above scheme, solid raw materials enter the discharge cylinder 8 through the inclined feed hopper 18. The material is initially collected by gravity and the inclination angle of the feed hopper 18 wall, ensuring that the material can smoothly enter the premixing area, preparing for subsequent crushing and mixing, and effectively preventing the feed inlet from being blocked.

[0035] Inside the feeding cylinder 8, a sleeve rod 19 is rotatably connected. The sleeve rod 19 extends to the outside of the feeding cylinder 8. A driven gear 20 is fixedly installed at one end of the sleeve rod 19 outside the feeding cylinder 8. A servo motor 21 is installed at the end of the feeding cylinder 8. A drive gear 22 is fixedly installed at the drive end of the servo motor 21. The drive gear 22 meshes with the driven gear 20, thereby driving it to rotate. A spiral feeding plate 23 is fixedly connected to the outside of the sleeve rod 19. The spiral feeding plate 23 extends to the area below the connection between the feeding hopper 18 and the feeding cylinder 8.

[0036] In the above scheme, the servo motor 21 drives the sleeve rod 19 to rotate through the meshing of the drive gear 22 and the driven gear 20. The spiral feed plate 23 fixed on the sleeve rod 19 rotates accordingly, forcibly conveying and initially mixing the material falling from the feed hopper 18, and pushing the material downward stably and controllably to achieve the initial feeding and mixing functions.

[0037] The sleeve rod 19 is fitted with an inner rotating rod 24, and the two ends of the inner rotating rod 24 extend to the outside of the sleeve rod 19. The end of the feeding cylinder 8 away from the mixing barrel 1 is fixedly provided with a motor base 25. A high-speed motor 26 is fixedly installed on the motor base 25. The rotating shaft of the high-speed motor 26 is fixedly connected to the inner rotating rod 24. The inner rotating rod 24 is located below the spiral feeding plate 23 and is equipped with a crushing blade 27.

[0038] In the above scheme, the high-speed motor 26 drives the inner rotating rod 24 to rotate at high speed, which in turn drives the crushing blade 27 installed below the spiral feed plate 23 to rotate at high speed, thereby powerfully crushing and dispersing the initially conveyed material, effectively solving the problem of material agglomeration, making the powdered material more uniform, and laying the foundation for subsequent uniform mixing.

[0039] A first nozzle 28 and a powder conveying pipe 29 are installed on the inner wall of the feeding cylinder 8 near the crushing blade 27. The first nozzle 28 is connected to a water-retaining conveying pump. A flow controller is installed between the first nozzle 28 and the water-retaining conveying pump. The powder conveying pipe 29 is used for conveying powdered modified waste. The feed end of the powder conveying pipe 29 is fixedly connected to a powder metering conveyor.

[0040] In the above scheme, the powder quantitative conveyor feeds the powdered modified fertilizer into the discharge cylinder 8 quantitatively and continuously through the powder conveying pipe 29; at the same time, the water-retaining conveying pump controls the supply of liquid modifier through the flow controller, and the first nozzle 28 atomizes the liquid and sprays it evenly onto the falling material, realizing the precise addition of liquid and powdered modifiers and significantly expanding the application range of the equipment.

[0041] Furthermore, a central controller (PLC) is included. The signal output terminals of the humidity sensor 5, electric actuator 12, drive motor 4, servo motor 21, high-speed motor 26, atomizing nozzle 6, flow controller, and pressure sensor 17 are all electrically connected to the signal input terminal of the central controller. The central controller is configured to receive the humidity signal from the humidity sensor 5 and the weight signal from the pressure sensor 17, and control the switching and flow rate of the atomizing nozzle 6, the feeding speed of the powder metering conveyor, and the rotation speed of the servo motor 21 according to the preset target humidity and target weight values, so as to realize closed-loop control of the amount of moisture and solid material added.

[0042] In the above scheme, the PLC collects the signals from the humidity sensor 5 and the pressure sensor 17 in real time, compares them with the preset target values ​​through the built-in logic program, and then outputs control signals to automatically adjust the flow rate of the atomizing nozzle 6, the feeding speed of the powder metering conveyor, and the rotation speed of the servo motor 21, so as to realize the automatic closed-loop control of the amount of moisture and solid materials added, ensuring the intelligent mixing and the stability of product quality.

[0043] The mixing equipment completes the mixing work through the cooperation of the premixing mechanism and the main mixing tank 1. Solid raw materials enter the feeding cylinder 8 through the inclined feeding hopper 18 and are conveyed by the spiral feeding plate 23, while being broken up by the high-speed crushing blades 27. The powder quantitative conveyor and the water-retaining agent nozzle are used to add powdered and liquid modifiers respectively to achieve premixing.

[0044] The premixed material enters the horizontal mixing tank 1 and is stirred and propelled by the spiral blades 3. During this process, the humidity sensor 5 monitors the humidity in real time, and the PLC control system dynamically adjusts the atomizing nozzles 6 to replenish water based on the feedback data, forming a closed-loop moisture control. The pressure sensor 17 monitors the weight change to assist in the proportioning. Finally, the uniformly mixed material is output by the electric push rod 12 controlling the opening and closing of the baffle 11.

[0045] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
