Description

Technical Field

[0001] This utility model relates to the field of fine water mist spraying technology, and in particular to an agricultural fine water mist spraying device. Background Technology

[0002] Agricultural fine water mist sprayers are highly efficient environmental control devices specifically designed for facility agriculture. They atomize water into micron-sized fine mists using a high-pressure system, making them an indispensable part of greenhouses. Their core components consist of a high-pressure pump, atomizing nozzles, piping, and an intelligent control system. They can precisely regulate humidity, temperature, and air freshness within the greenhouse, and are widely applicable to vegetable, flower, and seedling cultivation, improving crop quality and yield.

[0003] As the core component of agricultural fine water mist spraying devices, atomizing nozzles are easily clogged by incompletely dissolved pesticides, fertilizers, or impurities in the water due to their typically small nozzle orifice diameter. Therefore, spraying devices in greenhouses are generally equipped with filtration modules to intercept impurities in the water source.

[0004] However, in existing technologies, most filter modules are located inside the water inlet of the pipeline, making them difficult to replace and clean. Furthermore, the space at the pipeline inlet is limited, requiring frequent cleaning of the filter modules. This not only increases the workload of maintenance personnel and prolongs equipment downtime, but also may lead to a decrease in filtration efficiency due to untimely cleaning, resulting in insufficient water spray volume due to filter module blockage. Utility Model Content

[0005] The main purpose of this utility model is to provide an agricultural fine water mist spraying device, which improves the convenience and efficiency of filter module maintenance.

[0006] The technical solution of this utility model is as follows:

[0007] An agricultural fine water mist spraying device includes a water supply pipe, a water supply device, and an atomizing nozzle. The water supply pipe is detachably connected to the water supply device. The water outlet of the water supply device is equipped with a filter module, which includes a filter box, a filter sheet, and a dirt collection tank.

[0008] The filter box is equipped with a filter box outlet and a filter box inlet pipe. The filter box outlet and the filter box inlet pipe are detachably connected to the water supply pipe and the water supply device, respectively. The filter sheet is located at the end of the filter box outlet near the water supply pipe. The sludge collection tank is located on the side of the filter sheet facing the ground and is slidably connected to the inner wall of the filter box. The sludge collection tank is equipped with a sludge collection tank cover plate at the end away from the filter box. The sludge collection tank cover plate is embedded in the filter box and is equipped with a leak-proof structure.

[0009] In one possible implementation, the filter box inlet pipe is detachably connected to the filter box, and the inner wall of the filter box inlet pipe is provided with a number of baffles for assisting in stirring the pesticide and water-fertilizer mixture. The edges of the baffles are fixedly connected to the inner wall of the filter box inlet pipe, and the cross-section is arc-shaped.

[0010] In one possible implementation, the leak-proof structure includes a leak-proof sealing groove and a leak-proof sealing block. The leak-proof sealing groove is provided on the side of the filter box facing the sludge collection tank cover plate, and a leak-proof sealing block corresponding to the leak-proof sealing groove is provided on the side of the sludge collection tank cover plate facing the filter box. The leak-proof sealing block is embedded in the leak-proof sealing groove.

[0011] In one possible implementation, an electronic control module is included, and a pressure sensor is provided on the inner wall of the sludge collection tank, the pressure sensor being electrically connected to the electronic control module.

[0012] In one possible implementation, the filter module is provided with a filter box cover, which covers the filter box.

[0013] In one possible implementation, the filter element is detachably connected to the outlet of the filter box, and the edge of the filter element is provided with a reinforcing ring to increase the strength of the filter element.

[0014] In one possible implementation, the filter box and the filter box cover are connected by bolts, and a leak-proof sealing layer is provided between the filter box cover and the filter box.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] After the fine water mist spraying device is activated, water from the water supply unit enters the filtration module through the outlet. The water first flows into the inlet pipe of the filter box, where the baffles on the inner wall create multiple turbulences as the water flows through, further agitating the pesticide and fertilizer mixture for a more uniform mix. The water then flows to the filter plates, and the filtered impurities fall into the collection tank after the device stops operating. When the impurities in the collection tank accumulate to a certain level, the pressure sensor detects a pressure change. At this point, the staff pulls out the collection tank to perform maintenance on the filtration module.

[0017] The leak-proof structure of the sludge collection tank cover enhances the firmness and sealing of the connection with the filter box. Furthermore, the sludge collection tank and the inner wall of the filter box are connected by a sliding mechanism, facilitating easy access for maintenance personnel. When the device stops operating, the internal water pressure decreases, and the sludge collection tank can be easily removed by sliding along the inner wall of the filter box after removing the fasteners. This allows for quick cleaning of filtered impurities and maintenance of the filter elements, simplifying the cleaning process and saving time and labor costs.

[0018] Meanwhile, the detachable component design facilitates replacement and maintenance, extends the life of the device, ensures stable operation, improves maintenance speed and convenience, and enhances the efficiency and reliability of agricultural spraying. Attached Figure Description

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1-7 As shown in the figure, this embodiment proposes an agricultural fine water mist spraying device. The main structure includes a water supply pipe 1, a water supply device 2, and an atomizing nozzle 6. The water supply pipe 1 is connected to the water supply device 2 and can be detached. The outlet of the water supply device 2 is equipped with a filter module 3 to reduce the possibility of impurities in the water entering the water supply pipe 1 and causing blockage of the atomizing nozzle, thereby ensuring the smooth operation of the spraying device and extending the service life of the equipment.

[0032] The water supply device 2 is equipped with a water supply device inlet 22, and the water supply device 2 can be equipped with a built-in high-pressure water pump. The high-pressure water pump draws the external liquid used for spraying to the filter module 3 (the high-pressure water pump outlet 21 is connected to the filter box inlet pipe 312) and provides water pressure.

[0033] Specifically, the filter module 3 in this embodiment includes a filter box 31, filter elements 32, and a sludge collection tank 33. The filter box 31 is also provided with a filter box outlet 311 and a filter box inlet pipe 312, which are detachably connected to the water supply pipe 1 and the water supply device 2, respectively, facilitating the disassembly, repair, or replacement of the filter module 3 and reducing maintenance difficulty and cost. The filter elements 32 are located at the end of the filter box outlet 311 near the water supply pipe 1, and can complete filtration before the water flows into the water supply pipe 1, effectively reducing impurities entering the water supply pipe 1 and ensuring the smooth flow of the water supply pipe 1.

[0034] like Figure 7 As shown, the sludge collection tank 33 is located below the filter plate 32 and is slidably connected to the inner wall of the filter box 31. Its proximity to the filter plate 32 facilitates the collection of impurities. After the device stops working, the impurities filtered out by the filter plate 32 will fall into the sludge collection tank 33 due to their own weight. The sludge collection tank 33 has inclined surfaces at its edges and inside, allowing impurities to slide down along these surfaces. This sliding connection design makes it easier to pull out the sludge collection tank 33. Maintenance personnel do not need to disassemble complex parts; they can simply remove the fasteners and slide the sludge collection tank 33 along the inner wall of the filter box to pull it out, simplifying the cleaning process. A sludge collection tank cover 331 is located at the end of the sludge collection tank 33 furthest from the filter box. The cover 331 is embedded in the filter box 31 and has a leak-proof structure 4. The embedded cover 331 enhances the sealing performance, and the leak-proof structure 4 reduces the possibility of water leakage from the sludge collection tank 33, ensuring the stability of the device during operation.

[0035] like Figures 4-5As shown, the leak-proof structure 4 in this embodiment includes a leak-proof sealing groove 41 and a leak-proof sealing block 42. The filter box 31 has a leak-proof sealing groove 41 on the side facing the sludge collection tank cover 331, and the sludge collection tank cover 331 has a corresponding leak-proof sealing block 42 on the side facing the filter box 31. This ensures the precise fit between the two, creating conditions for tight integration and improving the reliability of leak prevention. The block structure further enhances the bonding strength between the two. Compared to planar sealing, the block structure increases the sealing contact area, increases sealing pressure, reduces gaps, and further improves the waterproofing and fixing effects. The leak-proof sealing block 42 is embedded in the leak-proof sealing groove 41, ensuring sealing while simplifying the operation of closing the sludge collection tank 33. Maintenance only requires simple pushing and pulling to seal and open, improving the sealing performance and convenience of this embodiment.

[0036] The sludge collection tank cover 331 and the filter box 31 are fixed and sealed with bolts, which improves the robustness and stability of this embodiment. At the same time, it further tightens the leak-proof sealing block 42 and the leak-proof sealing groove 41, enhancing their connection strength, preventing loosening and displacement, ensuring the leak-proof sealing block 42 is continuously pressurized, and improving sealing performance. It also allows the leak-proof sealing block 42 to fit more tightly into the leak-proof sealing groove 41, reducing gaps, strengthening waterproofing, and simplifying bolt installation and removal, balancing stability and convenience, and ensuring stable operation of this embodiment.

[0037] In this embodiment, the filter box inlet pipe 312 is detachably connected to the filter box 31. The inner wall of the filter box inlet pipe 312 is provided with a plurality of baffles 34 for assisting in stirring the pesticide and water-fertilizer mixture. The edges of the baffles 34 are fixedly connected to the inner wall of the filter box inlet pipe 312 and the cross-section is arc-shaped.

[0038] In this embodiment, the filter box inlet pipe 312 is detachably connected to the filter box 31, allowing the filter box inlet pipe 312 to be disassembled, cleaned, or replaced separately, reducing maintenance difficulty. When the filter box inlet pipe 312 is damaged or blocked, there is no need to replace the entire filter box 31, saving costs.

[0039] The inner wall of the filter box inlet pipe 312 is equipped with several baffles 34 to assist in stirring the pesticide and fertilizer mixture. These baffles create multiple sets of turbulence as water flows through, promoting thorough convection and mixing of the pesticide and fertilizer mixture, resulting in a more uniform mixture and improved utilization of pesticides and fertilizers. The edges of the baffles 34 are fixedly connected to the inner wall of the filter box inlet pipe 312, ensuring the stability of the baffles 34 under water flow impact and preventing them from loosening or falling off.

[0040] In typical agricultural spraying operations, when the device is used for greenhouse crops or spraying easily damaged crops such as seedlings and tender leaves, it is usually operated at a medium to low speed. At this time, the water pressure of the water supply device 2 is regulated to maintain a low level, and the water flow through the filter box inlet pipe 312 is at a moderate speed. Under these conditions, the baffle ribs 34 can fully convect and mix the flowing water, thereby assisting in stirring the pesticide and fertilizer mixture.

[0041] This embodiment also includes an electronic control module 5, which provides the basis for intelligent control and can receive and process relevant signals. A pressure sensor 35 is installed on the inner wall of the sludge collection tank 33 to monitor pressure changes caused by the accumulation of impurities in the tank in real time. The pressure sensor 35 is electrically connected to the electronic control module 5. When the pressure sensor 35 reaches a set threshold, it will send a signal to the electronic control module 5, which will then issue a maintenance signal to prompt maintenance personnel to clean the sludge collection tank 33, ensuring stable filtration and reducing the decrease in spray device efficiency due to impurity blockage.

[0042] In this embodiment, the electrical control module 5 preferably uses a PLC, specifically a Siemens S7-1200 series PLC. Its integrated analog input channel can receive 4-20mA signals from the pressure sensor 35, enabling pressure threshold comparison through programming. The built-in relay output can drive the maintenance reminder device, issuing a signal when the pressure exceeds the limit. This model features anti-interference design, supports expansion, and is easy to program, stably completing the intelligent control of impurity monitoring and maintenance reminders in the sludge collection tank 33, meeting the technical requirements of this embodiment.

[0043] In this embodiment, the filter element 32 is detachably connected to the outlet 311 of the filter box, facilitating the removal, cleaning, or replacement of the filter element. When the filter element 32 becomes clogged or damaged due to long-term use, maintenance and replacement can be performed without complicated operations, ensuring the continuous effectiveness of the filtration function. The filter element 32 has a reinforcing ring 321 on its edge to increase its rigidity, improving the structural stability of the filter element 32 under water flow impact, reducing the possibility of deformation or breakage due to excessive force, extending the service life of the filter element 32, and ensuring stable filtration performance.

[0044] In this embodiment, the filter box 31 is covered by a filter box cover 36 on the side away from the ground, providing a convenient passage for the inspection and replacement of the internal components of the filter box 31. Maintenance personnel can open the filter box cover 36 without flipping the device, reducing the difficulty of maintenance operations. The filter box 31 is embedded in the filter box cover 36, which not only enhances the overall structural stability of the filter box, but also effectively prevents the external environment from affecting the internal components of the filter box 31.

[0045] like Figure 3As shown, in this embodiment, the filter box 31 and the filter box cover 36 are connected by bolts, ensuring the airtightness of the connection and preventing loosening during operation. The bolt connection also facilitates disassembly, allowing maintenance personnel to easily open the filter box cover 36 to inspect or replace internal components, balancing connection reliability and maintenance convenience. The inner wall of the filter box cover 36 is covered with a leak-proof sealing layer 361, filling the gap at the connection between the filter box 31 and the filter box cover 36, further enhancing the airtightness of the connection, effectively preventing water leakage, and ensuring continuous and stable spraying operations.

[0046] This embodiment reduces the requirements for water sources. Even if water containing certain impurities is used, it can still meet the needs of spray irrigation after being treated by the filtration module 3, and effectively reduce the possibility of nozzle clogging. For example, the return water after irrigation or collected rainwater can be reused for irrigation after the impurities in the water are reduced by the filtration module 3, which not only saves water resources, but also improves the efficiency of water resource utilization.
