Description

Technical Field

[0001] This utility model relates to the field of fertilization device technology, specifically to an intelligent fertilization device for bio-organic fertilizer. Background Technology

[0002] With the development of modern agriculture, bio-organic fertilizers have been widely used in agricultural production due to their environmentally friendly and efficient characteristics. Bio-organic fertilizers are made from animal and plant residues through microbial fermentation and decomposition. They contain abundant organic matter and various nutrients, which can improve soil structure, enhance soil fertility, and promote crop growth.

[0003] Currently, there are various bio-organic fertilizer application devices on the market. For example, CN120092572A discloses a bio-organic fertilizer application device, which includes a frame, a fertilizer box, and a fertilization mechanism. By setting up operating components and linking the fertilization mechanism with the feeding mechanism, the two hollow insert plates of the fertilization mechanism can be intermittently inserted into the soil in layers for stratified fertilization.

[0004] Regarding the application of liquid bio-organic fertilizer, CN210328519U discloses a fertilization device for greenhouse vegetable carbon-based bio-organic fertilizer. This device has an installation ring on the inner wall of the fertilizer tank, with a micro-motor connected to the ring. The output shaft of the micro-motor is fixed to a rotating shaft, and multiple blades are arranged on the outer wall of the rotating shaft. These blades are located near the end of the transmission pipe. When the micro-motor operates, it drives the blades to rotate, thus breaking up clumps of fertilizer and preventing clogging of the transmission pipe. CN114175901A discloses a bio-organic fertilizer application device for rice cultivation. This device uses a rotating stirring rod to agitate the fertilizer in the fertilizer tank, preventing fertilizer accumulation at the outlet and blockage.

[0005] However, liquid bio-organic fertilizers have complex compositions and often contain incompletely decomposed organic residues (such as straw fragments and manure pellets). These particulate materials can easily cause nozzle blockage or partial blockage during fertilization. Although existing technologies employ mixing devices to prevent fertilizer clumping, there is still a lack of effective filtration and cleaning mechanisms for particulate materials that have already entered the delivery pipeline. When nozzles become clogged, it not only leads to uneven spraying and affects fertilization effectiveness, but also requires frequent shutdowns for cleaning or pretreatment of the fertilizer, significantly increasing the workload and time costs during fertilization.

[0006] Furthermore, existing filtration devices often require regular manual cleaning, a tedious and inefficient process. Once the filter becomes clogged with impurities, it not only affects fertilization effectiveness but can also lead to increased pressure in the pipeline, raising the risk of equipment failure. Therefore, designing an intelligent liquid biological organic fertilizer application device that can automatically clean the filter to solve the nozzle clogging problem and improve fertilization efficiency and uniformity has become an urgent technical challenge. Utility Model Content

[0007] The purpose of this invention is to provide an intelligent fertilization device for bio-organic fertilizer to solve the problem of nozzle clogging and improve fertilization efficiency and uniformity.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an intelligent bio-organic fertilizer application device, comprising a frame, wherein the frame is further provided with:

[0009] A fertilizer tank for storing liquid biological organic fertilizer;

[0010] The power supply control box is mounted on the frame.

[0011] A gas booster pump is fixedly mounted on the frame, and its gas booster output end is connected to the inner cavity of the fertilizer tank.

[0012] A bidirectional liquid supply pipeline, both ends of which are fixedly connected to the bottom of both ends of the fertilizer tank, with the middle part of the bidirectional liquid supply pipeline being the output end;

[0013] The nozzle is fixedly installed on the output end of the bidirectional liquid supply pipeline;

[0014] Two self-cleaning filter mechanisms are fixedly installed on the outer wall of the bidirectional liquid supply pipe and are located at the front end of the nozzle in the two liquid supply directions respectively.

[0015] In one feasible implementation, the frame is provided with: a mounting seat fixedly mounted on the top of the frame; two handrails extending from below the mounting seat toward the outside of the vehicle body, the two handrails being arranged in parallel; and support legs disposed below the handrails.

[0016] In one feasible implementation, an inclined liquid inlet is provided at the upper end of the side wall of the fertilizer tank, and a removable sealing cap is provided on the liquid inlet.

[0017] In one feasible implementation, a housing air supply pipe is provided on the output end of the gas booster pump, and the other end of the housing air supply pipe is connected to the top of the inner cavity of the fertilizer tank.

[0018] In one feasible embodiment, the self-cleaning filter mechanism includes: one end of an air distribution pipe connected to the air supply pipe of the housing; a filter cartridge fixedly mounted on the bidirectional liquid supply pipe; a first control valve and a second control valve fixedly mounted on the bidirectional liquid supply pipe on both sides of the filter cartridge; the first control valve and the second control valve are used to realize the backwashing of the filter cartridge by airflow; and both the first control valve and the second control valve are electrically controlled three-way valves.

[0019] In one feasible implementation, the gas distribution pipe includes a first branch pipe and a second branch pipe. One end of the first branch pipe is fixedly connected to the gas supply pipe of the housing, and the other end is connected to one of the first control valves. One end of the second branch pipe is fixedly connected to the first branch pipe, and the other end is connected to another first control valve. The second control valve is provided with an open discharge port.

[0020] In one feasible implementation, the filter cartridge includes a cylinder body, and a first intercepting mesh and a second intercepting mesh are further disposed inside the cylinder body.

[0021] In one feasible implementation, the fertilizer tank also has a constant pressure relief valve that can automatically release pressure, and the constant pressure relief valve is equipped with a pressure gauge.

[0022] In one feasible implementation, electromagnetic flowmeters are respectively installed on the bidirectional liquid supply pipes on both sides of the nozzle.

[0023] Compared with existing technologies, the beneficial effects of this invention are as follows: This intelligent bio-organic fertilizer application device, through the installation of a bidirectional liquid supply pipeline and a self-cleaning filtration mechanism, automatically activates a gas booster pump when the electromagnetic flowmeter detects blockage in one of the inlet channels of the bidirectional liquid supply pipeline, achieving high-pressure airflow backwashing and directly discharging impurities to the outside of the equipment. This ensures that the other inlet side of the bidirectional liquid supply pipeline can continuously supply fertilizer during the cleaning process, thus not delaying the fertilization progress; at the same time, no downtime is required for cleaning and maintenance, improving fertilization efficiency; the automatic monitoring and cleaning system reduces manual intervention and labor intensity; no pretreatment of fertilizer is required, simplifying pre-fertilization preparation; and it ensures uniform spray volume from the nozzles, improving fertilization quality. Compared with existing technologies, this invention solves the problem of nozzle blockage during liquid bio-organic fertilizer spraying, achieving continuity and uniformity in the fertilization process.

[0036] 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.

[0037] Please see Figures 1 to 5 A smart fertilization device for bio-organic fertilizer includes a frame 10, on which a fertilizer tank 20, a power supply control box 30, a gas booster pump 40, a two-way liquid supply pipeline 50, a nozzle 70, and two self-cleaning filter mechanisms 60 are installed.

[0038] Specifically, the fertilizer tank 20 is used to store liquid biological organic fertilizer and is fixedly installed on the upper part of the frame 10. The fertilizer tank 20 is made of high-strength, corrosion-resistant material and has a volume of 100 liters, which can meet the fertilization needs of large-scale farmland. An inclined liquid inlet 21 is provided at the upper end of the side wall of the fertilizer tank 20, and a removable sealing cap is provided on the inlet 21. The inlet 21 is inclined at a 45-degree angle to facilitate the addition of liquid fertilizer. The sealing cap uses a threaded connection to ensure that it will not loosen due to pressure during fertilization, thus preventing fertilizer leakage.

[0039] The power supply control box 30 is mounted on the frame 10, located on one side of the fertilizer tank 20. The power supply control box 30 integrates a power management system, a control circuit board, and an operation panel. The power management system includes a battery and charging circuit, providing 12V DC power to meet the operating requirements of the gas booster pump 40 and the electrically controlled valves. The control circuit board uses a single-chip microcomputer control system, capable of controlling the working status of each actuator according to a preset program. The operation panel is equipped with a power switch, a mode selection button, and status indicator lights for easy operation and monitoring by the operator.

[0040] A gas booster pump 40 is fixedly mounted on the frame 10, located below the fertilizer tank 20. The gas booster pump 40 is driven by a DC motor, with a maximum output pressure of 0.3 MPa and a flow rate of 50 L / min, providing a stable air pressure to the fertilizer tank 20. A tank air supply pipe 41 is installed at the output end of the gas booster pump 40, with the other end connected to the top of the inner cavity of the fertilizer tank 20. The tank air supply pipe 41 is made of pressure-resistant flexible tubing with an inner diameter of 10 mm and a wall thickness of 2 mm, ensuring it will not deform or break under high pressure.

[0041] The bidirectional liquid supply pipe 50 is fixedly connected at both ends to the bottom of the fertilizer tank 20, with the fertilizer output end in the middle. The bidirectional liquid supply pipe 50 is made of high-strength PVC material, with an inner diameter of 20mm and a wall thickness of 3mm, capable of withstanding the pressure inside the fertilizer tank 20 and ensuring smooth fertilizer flow. The design of the bidirectional liquid supply pipe 50 allows fertilizer to flow out from both ends of the fertilizer tank 20 simultaneously and then converge at the output end in the middle, improving fertilization efficiency.

[0042] The nozzle 70 is fixedly mounted on the output end of the bidirectional liquid supply pipe 50. The nozzle 70 features a fan-shaped nozzle design, with an adjustable spray angle of 60°-120° and a spray distance of 0.5-1 meter, which can be adjusted according to the planting density and row spacing of different crops. The nozzle 70 is made of a corrosion-resistant alloy, ensuring that it will not be corroded by fertilizer during long-term use.

[0043] Two self-cleaning filter mechanisms 60 are fixedly installed on the outer wall of the bidirectional liquid supply pipe 50 and located at the front end of the nozzle 70 in the two liquid supply directions, respectively. Each self-cleaning filter mechanism 60 includes a gas distribution pipe 61, a filter cartridge 62, a first control valve 63, and a second control valve 64. One end of the gas distribution pipe 61 is connected to the air supply pipe 41 of the housing, and the other end splits into two paths connected to the two first control valves 63. The gas distribution pipe 61 includes a first branch pipe 611 and a second branch pipe 612. One end of the first branch pipe 611 is fixedly connected to the air supply pipe 41 of the housing, and the other end is connected to one of the first control valves 63. One end of the second branch pipe 612 is fixedly connected to the first branch pipe 611, and the other end is connected to the other first control valve 63.

[0044] The filter cartridge 62 is fixedly mounted on the bidirectional liquid supply pipe 50. The filter cartridge 62 includes a cylinder body 621, inside which a first intercepting mesh 622 and a second intercepting mesh 623 are also installed. The cylinder body 621 is made of transparent material for easy observation of the filtration process. The first intercepting mesh 622 has a 100-mesh aperture and is used to intercept larger particulate impurities; the second intercepting mesh 623 has a 200-mesh aperture and is used to intercept fine impurities, ensuring that the sprayed fertilizer is free of impurities and preventing the nozzle 70 from clogging.

[0045] The first control valve 63 and the second control valve 64 are respectively fixedly installed on the bidirectional liquid supply pipes 50 on both sides of the filter cartridge 62. The first control valve 63 and the second control valve 64 are used to realize the airflow backwashing of the filter cartridge 62. Both the first control valve 63 and the second control valve 64 are electrically controlled three-way valves. The second control valve 64 is provided with an open discharge port. When backwashing is performed, the discharge port opens, and the impurities washed down can be discharged from the discharge port to keep the filtration system clean.

[0046] The fertilizer tank 20 also has an automatic pressure relief valve 80, which is equipped with a pressure gauge. The set pressure of the pressure relief valve 80 is 0.25 MPa. When the pressure inside the fertilizer tank 20 exceeds the set value, the valve automatically opens to release excess pressure and ensure the safe operation of the system. The pressure gauge has a range of 0-0.5 MPa and a scale accuracy of 0.01 MPa, allowing operators to monitor the pressure status inside the fertilizer tank 20 at any time.

[0047] Electromagnetic flow meters are installed on the bidirectional liquid supply pipes 50 on both sides of the nozzle 70. The electromagnetic flow meters have a measurement range of 0-100 L / min and an accuracy of ±1%, which can monitor the fertilizer flow in real time to ensure uniform fertilization. The electromagnetic flow meters are connected to the control system. When an abnormal flow is detected, the control system will issue an alarm and adjust the working status of the gas booster pump 40 to ensure the quality of fertilization. It is also used to detect whether there is normal fertilizer flow at the current location. If there is no flow or the flow is lower than the normal value, it indicates that the flow on the current side is abnormal and the filter cartridge 62 may be blocked. This sends a blockage signal to the control panel, and then the first control valve 63 and the second control valve 64 are activated to achieve airflow cleaning operation.

[0048] The frame 10 is equipped with a mounting base 11, two handrails 12, and support legs 13. The mounting base 11 is fixedly mounted on the top of the frame 10 for securing the fertilizer tank 20. The mounting base 11 is made of steel with an anti-corrosion treatment, ensuring it can firmly support the weight of the fertilizer tank 20. The two handrails 12 extend from below the mounting base 11 towards the outside of the vehicle body, and are arranged parallel to each other. The handrails 12 are 50cm long and 80cm high, facilitating the operator to move the device. The support legs 13 are located below the handrails 12 and are used for fixed support when the equipment is stopped.

[0049] The working principle of this intelligent bio-organic fertilizer application device is as follows:

[0050] First, liquid biological organic fertilizer is added to the fertilizer tank 20 through the inlet 21, and the sealing cap is tightened. The control system in the power supply control box 30 is then activated, and the control system controls the gas booster pump 40 to operate according to a preset program. The gas booster pump 40 forces air into the inner cavity of the fertilizer tank 20, creating a certain pressure inside. Under this pressure, the liquid fertilizer flows from the bottom of the fertilizer tank 20 into the bidirectional liquid supply pipe 50. After being filtered by the self-cleaning filter mechanism 60, the fertilizer is sprayed out from the nozzle 70, thus fertilizing the crops.

[0051] When the filter cartridge 62 needs cleaning (e.g., when the electromagnetic flowmeter detects the need for cleaning), the control system switches the operating states of the first control valve 63 and the second control valve 64, introducing compressed air generated by the gas booster pump 40 into the filter cartridge 62 through the air distribution pipe 61 to backwash the filter screen. The washed-off impurities are discharged through the discharge port of the second control valve 64, completing the self-cleaning process of the filtration system. The entire process is completed automatically by the control system without manual intervention, greatly improving work efficiency.

[0052] The electromagnetic flowmeter monitors the fertilizer flow rate in real time and feeds the data back to the control system. The control system adjusts the operating status of the gas booster pump 40 based on the flow data to ensure uniform fertilization. When the pressure inside the fertilizer tank 20 is too high, the constant pressure relief valve 80 automatically opens to release excess pressure and ensure safe system operation.

[0053] This intelligent bio-organic fertilizer application device features a simple structure and convenient operation, enabling precise application of liquid bio-organic fertilizer. The self-cleaning filter mechanism solves the clogging problem common in traditional fertilizer application devices, improving work efficiency and fertilizer quality. The bidirectional liquid supply design ensures more even fertilizer distribution, facilitating crop absorption and utilization. The entire device utilizes an electronic control system, achieving intelligent operation, reducing farmers' labor intensity, and improving agricultural production efficiency.
