Description

Technical Field

[0001] This utility model relates to the field of fertilizer mixing technology, specifically to an agricultural machinery fertilizer mixing device. Background Technology

[0002] A homogenizer for water-soluble fertilizer processing is a mixing device specifically designed for the production of water-soluble fertilizers. It is mainly used to ensure the uniform mixing of raw materials. Water-soluble fertilizers are fertilizers that can be completely dissolved in water and usually contain a variety of nutrients such as nitrogen, phosphorus, potassium, and trace elements. The use of homogenizers is crucial in the production process of water-soluble fertilizers because it can ensure the uniform distribution of various components, thereby ensuring the quality and effectiveness of the fertilizer.

[0003] A search revealed that patent application number CN202421435879.8 discloses a homogenizer for water-soluble fertilizer processing, which uses a stirring mechanism to mix fertilizers. While this device can mix fertilizers to a certain extent by using rotating stirring blades and a stirring shaft, it relies solely on the rotation of traditional stirring blades, resulting in low mixing efficiency and difficulty in quickly achieving uniform mixing of different fertilizers. Furthermore, the device lacks efficient use of power during the mixing process, requiring an external power source to drive the stirring mechanism, increasing operating costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an agricultural machinery fertilizer mixing device, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] An agricultural machinery fertilizer mixing device includes a square tube with culverts connected to both ends of the square tube;

[0007] A suction tube is installed at the bottom of the square tube, and a flexible sealing plate is installed inside the square tube. The flexible sealing plate is located above the suction tube inside the square tube. A generator is installed inside the culvert, and a turbofan is installed at the output end of the generator.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the culvert is a circular pipe, and the culvert is connected to the square pipe through a transition pipe.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The smooth inner wall of the circular culvert reduces the resistance of the fluid medium during flow compared to other shapes, making the medium flow more smoothly and helping to increase the flow rate and volume of the liquid medium, thereby improving the efficiency of fertilizer mixing. The transition pipe enables a smooth transition between the culvert and the square pipe, avoiding eddies and other adverse conditions on the medium flow caused by sudden changes in pipe diameter, ensuring the stability of the medium flow in the entire device, and providing good hydrodynamic conditions for the uniform mixing of fertilizer.

[0012] Furthermore, the flexible sealing plate is provided with a fixing strip and a strong magnet at both ends.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The fixing strip provides a stable support point for the flexible sealing plate, ensuring that the flexible sealing plate can fit tightly inside the square tube when closed, preventing leakage or premature mixing of the medium inside the square tube and the fertilizer inside the suction tube when not mixed. The strong magnet forms a magnetic interaction structure with the electromagnet. When the electromagnet is energized and generates magnetic force, it can generate a repulsive force with the strong magnet, which helps the flexible sealing plate to open quickly and reliably. This makes up for the problems of untimely opening and instability that may occur when relying solely on pressure difference to open the sealing plate, and enhances the reliability and stability of the device operation.

[0015] Furthermore, an electromagnet is installed on the lower surface of the square tube on one side of the straw, and the generator is electrically connected to the electromagnet via a cable.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The electrical connection between the electromagnet and the generator enables the device to form a self-sufficient energy supply system, eliminating the need for an additional power source to power the electromagnet, thus reducing equipment costs and energy consumption. The electromagnet is installed on the suction tube side of the lower surface of the square tube, and its reasonable positioning allows it to precisely generate magnetic force with the strong magnet on the flexible sealing plate. This ensures that when the liquid medium flows and the generator generates current, the electromagnet can promptly generate magnetic force to assist the flexible sealing plate in opening, thus enabling the smooth start-up of the fertilizer mixing process.

[0018] Furthermore, the position of the electromagnet corresponds to the position of the strong magnet.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] This ensures that the electromagnet and the strong magnet can generate the maximum magnetic force, so that the repulsive force generated by the electromagnet after being energized can act on the strong magnet efficiently and stably, thereby more effectively assisting the opening of the flexible sealing plate; it avoids the dispersion of magnetic force and weakening of force due to positional deviation, ensuring the reliability and consistency of the opening process of the flexible sealing plate, and improving the stability of the device and the efficiency of fertilizer mixing.

[0021] Furthermore, an end cap is installed at the end of the generator, and the generator is sealed inside the housing by the end cap.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The sealed installation of the end cap and the outer casing can effectively prevent liquid media, fertilizer particles, etc. from entering the generator, avoiding damage to the generator due to foreign objects and extending the service life of the generator. At the same time, the good sealing performance can also ensure that the generator operates normally in complex agricultural operating environments such as humid and dusty conditions, enhancing the environmental adaptability and overall reliability of the device, and reducing equipment maintenance costs and the probability of failure.

[0024] This utility model provides a fertilizer mixing device for agricultural machinery. It has the following beneficial effects:

[0025] By connecting culverts, square tubes, and transition tubes, and designing suction pipes and flexible sealing plates, the principle of pressure reduction inside the square tube when the liquid medium flows is utilized to open the flexible sealing plate, realizing the mixing and transportation of the liquid medium inside the square tube and the medium inside the suction pipe. This design can effectively mix different fertilizer media, improving the uniformity and effect of mixing.

[0026] The generator installed inside the culvert interacts with the medium flowing inside the square tube via a turbofan. When the turbofan is driven to rotate by the medium, the generator produces an electric current. This design cleverly utilizes the power of the fluid, converting it into electrical energy to power the electromagnet. No external power source is required, offering advantages such as energy saving and environmental protection, and reducing the operating costs of the equipment.

[0027] The flexible sealing plate has fixing strips and strong magnets at both ends, and an electromagnet is installed on the lower surface of the square tube. A generator is electrically connected to the electromagnet via a cable. When the generator provides current to the electromagnet, the electromagnet and the strong magnet generate a repulsive force, assisting the flexible sealing plate in opening. This design increases the reliability of the flexible sealing plate's opening, ensuring smooth fertilizer mixing under different operating conditions and reducing the possibility of uneven mixing or equipment failure due to poor sealing plate opening.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1 to 5 As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1

[0040] An agricultural machinery fertilizer mixing device includes a square tube 2, with culverts 1 connected to both ends of the square tube 2. The culverts 1 are circular tubes, and the culverts 1 and square tube 2 are connected by a transition pipe 3. The inner wall of the circular culvert 1 is smooth, which reduces the resistance of the fluid medium during flow compared to other shapes, making the medium flow more smoothly and helping to increase the flow rate and volume of the liquid medium, thereby improving the efficiency of fertilizer mixing. The transition pipe 3 enables a smooth transition between the culvert 1 and the square tube 2, avoiding eddies or other unfavorable conditions for medium flow caused by sudden changes in pipe diameter, ensuring the stability of the medium flow within the entire device, and providing good hydrodynamic conditions for uniform fertilizer mixing. A suction pipe 5 is installed at the bottom of the square tube 2. The suction pipe 5 is inserted into the fertilizer to be mixed, and a flexible sealing plate 7 is installed inside the square tube 2. The flexible sealing plate 7 is located above the suction pipe 5 inside the square tube 2. When there is liquid in the culvert 1 and the square tube 2... When the medium flows, the pressure inside the square tube 2 decreases, and the flexible sealing plate 7 is driven to open. At this time, the liquid medium inside the square tube 2 will draw in the medium in the suction pipe 5 as it flows, thereby mixing and transporting the liquid medium inside the square tube 2 with the medium in the suction pipe 5. A generator 8 is installed inside the culvert 1. A turbofan 802 is installed at the output end of the generator 8, and an end cover 801 is installed at the end of the generator 8. The generator 8 is sealed inside the outer casing by the end cover 801. The sealing installation of the end cover 801 and the outer casing can effectively prevent liquid medium, fertilizer particles, etc. from entering the generator 8, avoiding damage to the generator 8 due to foreign objects entering, and extending the service life of the generator 8. At the same time, the good sealing performance can also ensure that the generator 8 operates normally in complex agricultural operating environments such as humid and dusty conditions, enhancing the environmental adaptability and overall reliability of the device, and reducing equipment maintenance costs and the probability of failure.

[0041] Example 2

[0042] To further improve the sealing performance, opening reliability, and energy efficiency of fertilizer mixing devices, for example, such as Figures 1 to 5As shown, this utility model also includes: a fixing strip 701 and a strong magnet 702 respectively provided at both ends of the flexible sealing plate 7. The fixing strip 701 provides a stable support point for the flexible sealing plate 7, ensuring that the flexible sealing plate 7 can be tightly fitted inside the square tube 2 when closed, preventing leakage or premature mixing of the medium inside the square tube 2 and the fertilizer inside the straw 5 when not mixed; the strong magnet 702 forms a magnetic interaction structure with the electromagnet 6. When the electromagnet 6 is energized and generates magnetic force, it can generate a repulsive force with the strong magnet 702, assisting the flexible sealing plate 7. The rapid and reliable opening mechanism overcomes the problems of untimely and unstable opening that may occur when relying solely on pressure difference to open the sealing plate, thus enhancing the reliability and stability of the device's operation. An electromagnet 6 is installed on the lower surface of the square tube 2, located on one side of the suction tube 5, and the generator 8 is electrically connected to the electromagnet 6 via cable 4. When the turbine fan 802 of the generator is driven to rotate by the medium flowing inside the square tube 2, the generator 8 generates current to power the electromagnet 6. The electrical connection between the electromagnet 6 and the generator 8 enables the device to form a self-sufficient energy supply system. No additional power supply is required for electromagnet 6, reducing equipment costs and energy consumption. Electromagnet 6 is installed on the lower surface of square tube 2, next to the suction tube 5, with a reasonable positioning that allows it to precisely interact with the strong magnet 702 on the flexible sealing plate 7. This ensures that when the liquid medium flows and the generator 8 produces current, electromagnet 6 promptly generates magnetic force to assist in opening the flexible sealing plate 7, facilitating the smooth start of the fertilizer mixing process. The position of electromagnet 6 corresponds to the position of strong magnet 702. When electromagnet 6 is energized and generates magnetic force, it repels strong magnet 702, pushing it away and thus assisting in opening the flexible sealing plate 7. This ensures maximum magnetic force between electromagnet 6 and strong magnet 702, allowing the repulsive force generated by electromagnet 6 to act efficiently and stably on strong magnet 702, thereby more effectively assisting in opening the flexible sealing plate 7. It avoids magnetic dispersion and weakened force due to positional deviations, ensuring the reliability and consistency of the opening process of the flexible sealing plate 7, and improving the stability of the device and the efficiency of fertilizer mixing.

[0043] Working principle:

[0044] Position the entire agricultural machinery fertilizer mixing device in a suitable working position and insert the suction tube 5 into the fertilizer to be mixed. At this time, the flexible sealing plate 7 is in the closed state, preventing the medium inside the square tube 2 from directly contacting the fertilizer inside the suction tube 5.

[0045] When the device is started, the liquid medium begins to flow in the culvert 1 and the square tube 2. According to the principles of fluid mechanics, the pressure inside the square tube 2 decreases as the liquid medium flows through it.

[0046] As the pressure inside square tube 2 decreases, the flexible sealing plate 7 experiences an upward force due to the pressure difference. Simultaneously, the turbine fan 802 of the generator 8 inside culvert 1 is driven to rotate by the flowing medium, generating current that powers the electromagnet 6 mounted on the lower surface of square tube 2 via cable 4. When energized, the electromagnet 6 generates magnetic force, which repulses the strong magnet 702 on the flexible sealing plate 7, assisting in opening the flexible sealing plate 7.

[0047] After the flexible sealing plate 7 is opened, the liquid medium in the square tube 2 will draw the fertilizer medium in the suction tube 5 when it flows. By using the suction and pressure difference of the fluid, the liquid medium in the square tube 2 and the fertilizer medium in the suction tube 5 are fully mixed and transported to achieve a uniform mixing process of fertilizer.

[0048] After the fertilizer mixing task is completed, the device stops operating, the liquid medium stops flowing, the generator 8 no longer generates current, the electromagnet 6 loses its magnetic force, and the flexible sealing plate 7 closes under its own gravity, completing one fertilizer mixing process.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
