Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a spraying platform. Background Technology

[0002] Agricultural spraying systems are essential equipment in modern agriculture for crop protection and fertilization. They achieve efficient management of farmland by spraying liquids such as pesticides and fertilizers. Traditional spraying systems typically use a fixed spraying pattern, which easily leads to problems such as overspraying, missed areas, and uneven spraying, affecting crop yields and potentially causing environmental pollution. With the development of precision agriculture technology, precision spraying systems are gradually being promoted and applied. Through sensors, intelligent control algorithms, and other technologies, they can achieve precise application of pesticides based on crop needs and environmental conditions, effectively improving the shortcomings of traditional spraying methods.

[0003] However, numerous challenges remain in the testing, promotion, and production of precision spraying systems. For example, in system function demonstrations and product showcases, directly transporting spraying vehicles for on-site displays is not only extremely costly in terms of manpower and resources, but also presents significant inconvenience due to the large size of the equipment. Furthermore, spraying vehicles generate considerable noise during actual testing, making it difficult to conduct long-term continuous durability tests indoors or in confined spaces, especially regression testing that can last for months without interruption. Simultaneously, traditional methods for product testing after production line assembly also suffer from low efficiency and high costs, hindering quality control in large-scale production.

Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following description, in conjunction with the accompanying drawings and embodiments, is provided. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0023] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0024] Please see Figure 1 One embodiment of this application provides a spraying stand 001, which can simulate the working state of a real agricultural spraying stand 001. It is suitable for application scenarios such as functional verification, control software testing, and long-term operational reliability assessment of the precision spraying stand 001. This spraying stand 001 enables performance testing of key components, providing an effective experimental means for product development and quality control.

[0025] Please see Figure 1 and Figure 2 The spraying platform 001 includes a support 100, a controller 200, and a box 300, a pump 400, an electronically controlled integrated valve 500, and a nozzle assembly 600 connected in sequence by pipes.

[0026] The housing 300 is mounted on the support 100 and has a cavity 310 for containing the spray liquid. The pump body 400 is mounted on the support 100 and is used to provide driving force for the spray liquid in the pipeline. The controller 200 is electrically connected to the electronically controlled integrated valve 500 and is also mounted on the support 100. The nozzle assembly 600 is located inside the housing 300 and is controlled by the electronically controlled integrated valve 500 to spray the spray liquid.

[0027] The modular design integrates the housing 300, pump 400, electronically controlled integrated valve 500, and nozzle assembly 600, simulating the operating environment of a real spraying stand 001. This results in a compact structure for easy transport and display of the spraying stand 001. The nozzle assembly 600, integrated within the housing 300, reduces spray liquid splashing and waste, and can be used for functional demonstrations, software testing, and durability verification of the precision spraying stand 001. The controller 200, in conjunction with the electronically controlled integrated valve 500, enables precise control of spray liquid flow and start / stop, improving testing and production inspection efficiency.

[0028] In some embodiments, the spraying liquid can be selected from different media according to the testing requirements, including but not limited to water, pesticide solutions, liquid fertilizers, and other commonly used agricultural spraying liquids. Simulated liquids with similar physicochemical properties, such as aqueous solutions containing dyes, can also be used for demonstration tests to observe the spraying effect. When selecting a liquid, compatibility with the system materials and suitability for the testing purpose should be considered; further details are omitted here.

[0029] In some embodiments, the bracket 100 includes a first frame 110 and a second frame 120 located on the first frame 110. The first frame 110 has a first mounting space 111, and the pump body 400 is disposed in the first mounting space 111.

[0030] The electronically controlled integrated valve 500 is mounted on the second frame 120, the second frame 120 has a second installation space 121, and the housing 300 is located in the second installation space 121.

[0031] In some embodiments, both the first frame 110 and the second frame 120 are constructed of aluminum profiles. The first frame 110 includes a cuboid frame composed of multiple profiles, with a first mounting space 111 formed inside the frame. The second frame 120 includes a mounting rod 122 and two support rods 123. The two support rods 123 are fixed to the upper surface of the first frame 110, and the mounting rod 122 is fixed to one end of the two support rods 123 away from the first frame 110, thereby enclosing the second mounting space 121. The electrically controlled integrated valve 500 is fixed to the mounting rod 122, and the controller 200 is fixed to the support rods 123.

[0032] In some embodiments, a removable shielding plate 116 is provided on the outer side of the first frame 110 to effectively protect the pump body 400 installed in the first installation space 111 and prevent the external environment from causing pollution or mechanical damage to the pump body 400.

[0033] The shielding plate 116 has pipe holes 1161 adapted to the pipe size, which facilitates the installation and arrangement of pipes. The shielding plates 116 on both sides are also provided with ergonomic hand grooves 1162, so that operators can hold and carry the spraying platform 001.

[0034] Please see Figure 2 and Figure 3 In some embodiments, the electronically controlled integrated valve 500 includes a filter 510, a pressure regulating chamber 520, a main valve 530, a pressure regulating valve 540, a proportional valve 550, a flow meter 560, a sectional valve 570, and a pressure gauge 580 connected in sequence.

[0035] Filter 510 filters impurities in the spray fluid, pressure stabilizing chamber 520 buffers pressure fluctuations, main valve 530 controls pipeline on / off, pressure regulating valve 540 regulates system working pressure, proportional valve 550 achieves precise flow control, flow meter 560 monitors real-time flow data, sectional valve 570 provides zone control, and pressure gauge 580 displays pipeline pressure status. The integrated design of the electrically controlled integrated valve 500, through the coordinated operation of its components, enables stable pressure control, precise flow regulation, and independent management of multiple zones on the spray platform 001.

[0036] The system includes multiple sectional valves 570, each connected to a nozzle assembly 600, enabling independent control of each zone. This allows for simulating the differentiated spraying needs of different areas in actual operations, testing the performance parameters of individual nozzles 620, and verifying the system stability of multiple nozzles 620 working together. Furthermore, the sectional control method facilitates rapid fault location during testing, improving detection efficiency.

[0037] In some embodiments, the nozzle assembly 600 includes a spray bar 610 and a plurality of nozzles 620 disposed on the spray bar 610. The spray bar 610 has a flow channel (not shown) inside and connects to the plurality of nozzles 620, enabling the plurality of nozzles 620 to obtain a stable flow supply. The spray bar 610 is connected to a corresponding section valve 570 through a pipe, which maintains the independence of each nozzle assembly 600 and simplifies the pipeline layout, facilitating the modular assembly and maintenance of the test system.

[0038] In some embodiments, the housing 300 is transparent, allowing operators to directly observe the remaining liquid level and the actual working condition of the nozzle assembly 600. The transparent material maintains the structural strength of the housing 300 while enabling visual monitoring of the spraying process. This helps testers to understand the correlation between system operating parameters and spraying effects in real time, providing an intuitive reference for data collection and analysis.

[0039] Please see Figure 3 and Figure 4 In some embodiments, the spraying stand 001 includes a liquid inlet three-way valve 700, which has a first connection port 710, a second connection port 720 and a third connection port 730. The first connection port 710 is connected to the cavity 310 of the housing 300 through a pipe, the second connection port 720 is connected to the pump body 400 through a pipe, and the third connection port 730 is connected to a replenishment pipe 740 for connecting to an external replenishment system.

[0040] In some embodiments, the external replenishment system may include various liquid supply devices, such as storage tanks, mixing tanks, and pesticide dosing machines, which are commonly used agricultural equipment. It may also be connected to a tap water system for direct water replenishment. Depending on the testing requirements, the system can provide different types of spraying media, such as clean water, pesticide stock solution, and fertilizer solution, and can achieve quantitative replenishment through an externally configured flow control device. The connection between the external replenishment system and the spraying stand 001 can be achieved using a quick-connect coupling for easy assembly and disassembly.

[0041] In some embodiments, the spraying platform 001 includes a liquid outlet three-way valve 800, which has a fourth connection port 810, a fifth connection port 820 and a sixth connection port 830. The fourth connection port 810 is connected to the pump body 400 through a pipe, the fifth connection port 820 is connected to the water inlet of the electronically controlled integrated valve 500 through a pipe, and the sixth connection port 830 is connected to a drain pipe 840 for discharging the spraying liquid in the tank 300.

[0042] In some embodiments, the inlet of the electronically controlled integrated valve 500 is the inlet of the filter 510.

[0043] In some embodiments, the spraying platform 001 has a replenishment state, a circulation state, and a draining state.

[0044] When in the replenishment state, the inlet three-way valve 700 blocks the pipe connecting the tank 300 and connects the pipe connecting the pump body 400 and the replenishment pipe 740. The outlet three-way valve 800 blocks the drain pipe 840 and connects the pipe connecting the pump body 400 and the filter 510.

[0045] When in circulation, the inlet three-way valve 700 blocks the replenishment pipe 740 and connects the pipe connecting the housing 300 and the pipe connecting the pump body 400. The outlet three-way valve 800 blocks the drain pipe 840 and connects the pipe connecting the pump body 400 and the inlet of the electric control integrated valve 500.

[0046] When in the draining state, the inlet three-way valve 700 blocks the replenishment pipe 740 and connects the pipe connecting the housing 300 and the pipe connecting the pump body 400. The outlet three-way valve 800 blocks the inlet of the electrically controlled integrated valve 500 and connects the pipe connecting the pump body 400 and the drain pipe 840.

[0047] The inlet three-way valve 700 and outlet three-way valve 800 work together to enable switching between three operating states of the spraying stand 001. In replenishment mode, it can quickly connect to an external liquid supply system to replenish the medium; in circulation mode, it maintains normal spraying operations within the system; and in drainage mode, it facilitates emptying the pipeline after testing. This integrated control solution significantly improves testing efficiency, enabling the spraying stand 001 to perform media replacement and system cleaning without disassembling the pipeline, making it particularly suitable for R&D verification scenarios that require frequent switching of test media.

[0048] In some embodiments, the first frame 110 includes a mounting base plate 112, a pump body fixing plate 113, and an elastic member 114 connecting the two. The mounting base plate 112 is horizontally disposed in the first mounting space 111. Figure 2 At the bottom, the pump body 400 is fastened to the pump body fixing plate 113 by bolts.

[0049] The system includes four elastic elements 114, which are installed at the four corners of the pump body fixing plate 113 and form a flexible connection with the mounting base plate 112. These elements are used to absorb the vibration of the pump body 400 during operation, reduce the energy transmitted to the first frame 110, thereby ensuring the stability of the system operation and reducing noise.

[0050] The elastic element 114 can be made of various damping components, including but not limited to rubber damping pads, spring dampers, polyurethane damping blocks, and other components with elastic deformation characteristics. These components need to have appropriate stiffness coefficients and durability to effectively absorb the vibration energy of the pump body 400. Corrosion-resistant and aging-resistant elastic materials are preferred to ensure long-term reliable operation in the humid environment commonly encountered in agricultural spraying platforms 001.

[0051] In some embodiments, the first frame 110 further includes a buffer 115, which is disposed between the mounting base plate 112 and the pump body fixing plate 113 and is located within the area enclosed by four elastic members 114, so as to further enhance the shock absorption performance of the first frame 110 and the stability of the pump body fixing plate 113. Through elastic support, a secondary buffer structure is formed between the mounting base plate 112 and the pump body fixing plate 113, reducing the risk of pipeline loosening caused by vibration and extending the service life of the equipment.

[0052] The buffer component 115 can be made of rubber buffer pads, polyurethane buffer blocks, disc springs, or air cushion buffers, etc., which have compression and rebound characteristics. These components need to have appropriate load-bearing capacity and damping characteristics to effectively absorb vertical impact vibrations. Oil-resistant and aging-resistant elastic materials are preferred to ensure long-term stable buffering performance in the humid and dusty working environment of the spraying platform 001.

[0053] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
