Description

Technical Field

[0001] This utility model belongs to the field of facility agriculture equipment technology, and in particular relates to a fertilizer and pesticide dispensing device for sprinkler irrigation machines. Background Technology

[0002] In large-scale facility agriculture, sprinkler irrigation machines, as core irrigation equipment, need to work in conjunction with fertilizer and pesticide dispensing systems to achieve precise fertilization and pesticide application, ensuring crop yield and quality. However, existing fertilizer and pesticide dispensing methods for sprinkler irrigation machines have several technical shortcomings and are difficult to adapt to the needs of modern production: First, it is highly dependent on manual labor and has low operational precision. Traditional equipment requires manual application of solid fertilizers, pouring of liquid fertilizers and pesticides, and manual observation of liquid levels to adjust the ratio. This is not only labor-intensive, but also prone to fluctuations in fertilizer and pesticide concentrations due to human error. This can result in crops being burned by excessively high concentrations or the desired effect being achieved by insufficient concentrations. At the same time, manual operation cannot meet the continuous operation requirements of large sprinkler irrigation machines, which can easily lead to operation interruptions.

[0003] Secondly, incomplete dissolution of solid fertilizers can easily lead to equipment malfunctions. Existing equipment often dissolves solid fertilizers simply by stirring, which can easily cause granular sedimentation. These sediments, once they enter the irrigation pipeline with the solution, can clog the nozzles and branch pipes, requiring the machine to be shut down for disassembly and cleaning. This not only reduces operational efficiency and shortens the service life of the pipelines, but also leads to uneven fertilizer and pesticide concentrations in the future.

[0004] Third, improper handling of pesticide residues poses risks of waste and pollution. Traditional equipment lacks pesticide bottle cleaning devices, and directly discarding pesticide residues on the inner wall of the bottle will cause waste and environmental (soil and water) pollution; if unwashed bottles are put into the dissolving tank, impurities will be introduced, further increasing the probability of nozzle clogging.

[0005] Fourth, the filtration system has poor reliability and lacks remote control capabilities. Existing equipment mostly uses single-element filters with small filtration areas, which are prone to clogging due to impurities and require frequent shutdowns to replace the filter elements. At the same time, the equipment lacks remote monitoring and control functions, requiring staff to be on-site. Sudden malfunctions (such as pump shutdown or pipeline leaks) are difficult to respond to in a timely manner, which can easily lead to missed application of fertilizers and pesticides in the field.

[0006] The aforementioned problems have hindered the development of automation and precision in large-scale agriculture, and there is an urgent need for a highly integrated and automated sprinkler irrigation system with fertilizer and pesticide dispensing equipment to solve these problems.

The filter inlets of the two self-cleaning filters are connected to the pre-filter pipe, the filter outlets of the two self-cleaning filters are connected to the fertilizer and pesticide liquid output pipe, and the filter drain outlets of the two self-cleaning filters are connected to the return liquid pipe. The return liquid from the drain outlet allows the unfiltered residual liquid to flow back to the fertilizer and pesticide water tank for reprocessing. Adjustable manual ball valves are installed on the pipes connecting the filter drain outlets and the return liquid pipes. By adjusting the opening of the manual ball valves, the flow resistance inside the filter is changed, thereby adjusting the direction of water flow distribution.

[0016] Preferably, the fertilizer and pesticide tank has a volume of 8-12 cubic meters, which can dissolve 2-3 tons of solid fertilizer at one time, and is suitable for sprinkler irrigation of 100-200 mu of land. It is also suitable for use with a circular pointer sprinkler.

[0022] Preferably, the liquid fertilizer pump is a three-phase vortex self-priming pump (K-1.5WZBS-55K1 type).

[0023] The working principle of this utility model revolves around five core processes: "automated dissolution and preparation, efficient mixing, continuous filtration, precise output, and remote control," as detailed below: 1. Fertilizer and pesticide application and pretreatment: Solid fertilizers are directly added to the fertilizer and pesticide tank according to the operational requirements; liquid fertilizers are quantitatively delivered to the fertilizer and pesticide tank by a liquid fertilizer pump through a liquid fertilizer injection pipe; pesticides are first placed in the pesticide tank and dissolved by injecting clean water (the water volume is controlled by a manual dissolving valve) through a dissolving pipe. At the same time, the pesticide bottle is opened using a tower-shaped bottle opener, and the bottle washing nozzle sprays clean water to rinse the pesticide residue on the inner wall of the bottle. The washing solution and the pesticide solution are then combined and flowed into the pesticide tank.

[0024] 2. Solution preparation and mixing: Based on the liquid level data of the fertilizer and pesticide tank fed back by the liquid level sensor, the controller automatically opens the water injection electric valve to inject a set amount of clean water into the fertilizer and pesticide tank; then, 1-3 stirring motors are started, and the impellers rotate to initially mix the solution; at the same time, the shear pump is started to shear and disperse the solid fertilizer particles in the fertilizer and pesticide tank to ensure that the solid fertilizer is fully dissolved and to avoid particle sedimentation.

[0025] 3. Circulating Filtration and Self-Cleaning: The mixed fertilizer solution enters the shear pump through the outlet pipe, and after being pressurized, it is transported to the self-cleaning filter group through the pre-filter pipe; the solution passes through the cylindrical filter screen to filter impurities, and the filtered clear liquid enters the fertilizer solution output pipe; during the filtration process, the water flow drives the filter screen brush to rotate and scrub the outer wall of the cylindrical filter screen to prevent the filter screen from clogging, and the impurities are returned to the fertilizer water tank for reprocessing through the return pipe with the sewage liquid; by adjusting the opening of the manual ball valve, the water flow ratio of the two parallel filters is distributed to ensure filtration efficiency and continuous operation.

[0026] 4. Precise output and parameter control: The controller starts the fertilizer and pesticide high-pressure pump according to the preset fertilizer and pesticide parameters (such as concentration and flow rate). The filtered fertilizer and pesticide solution is delivered to the sprinkler irrigation machine through the fertilizer and pesticide solution output pipe. The fertilizer and pesticide flow sensor collects the output flow data in real time and feeds it back to the controller. The controller dynamically corrects the output flow by adjusting the opening of the fertilizer and pesticide solution electric valve and the speed of the fertilizer and pesticide high-pressure pump to ensure that the fertilizer and pesticide concentration is uniform and stable.

[0027] 5. Remote control and real-time monitoring: Staff can establish two-way communication with the controller via a remote terminal using a 4G communication module, and can remotely send control commands such as equipment start / stop and parameter adjustment; real-time data from liquid level sensors and fertilizer / pesticide flow sensors are synchronously uploaded to the remote terminal, making it easy for staff to monitor the remaining solution and output status; cameras collect video of the equipment operation scene and transmit it to the remote terminal via the 4G communication module to achieve visual monitoring of the equipment's operating status.

[0028] Compared with the prior art, the advantages of this utility model are as follows: 1. High degree of automation, significantly reducing labor costs. The equipment achieves fully automated control of the fertilizer and pesticide application, dissolution, mixing, filtration, and output process, eliminating the need for on-site human supervision. It can be operated remotely via a terminal, making it suitable for large-scale field operations.

[0029] 2. Uniform mixing of fertilizers and pesticides ensures better application results. Through the combined action of a stirring device and a shear pump, solid fertilizer particles are thoroughly sheared and dispersed, preventing sedimentation. Pesticides are dissolved and cleaned of residues before full utilization, ensuring a uniform and stable concentration of fertilizers and pesticides.

[0030] 3. Highly efficient and stable filtration, ensuring continuous equipment operation. A parallel self-cleaning filter assembly, combined with a water-driven filter brush for automatic cleaning, prevents filter clogging. Unfiltered impurities are returned for reprocessing, improving filtration efficiency and continuity.

[0031] 4. Precise control and visual monitoring enhance operational reliability. Real-time data feedback from level and flow sensors allows the controller to dynamically adjust output parameters, ensuring precise application of fertilizers and pesticides. A 4G communication module and camera enable remote data viewing and video monitoring, facilitating timely understanding of equipment operating status.

[0032] 5. Highly adaptable and widely applicable. The equipment's volume and parameters are designed to accommodate plots of land ranging from 100 to 200 acres. It can be used in conjunction with circular pointer sprinkler irrigation systems and is compatible with the application of solid fertilizers, liquid fertilizers, and pesticides, meeting the planting needs of different crops.
