Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation equipment technology, specifically to an anti-clogging micro-sprinkler device. Background Technology

[0002] As an important oilseed crop, camellia oleifera has strict requirements for the precision and uniformity of water and fertilizer supply during its growth process. Currently, the mainstream irrigation methods in camellia oleifera planting are traditional flood irrigation, ordinary drip irrigation and simple micro-sprinkler irrigation. Among them, simple micro-sprinkler irrigation is a common method for irrigating mature camellia oleifera plants. However, the existing micro-sprinkler heads have many technical defects and are difficult to adapt to the actual irrigation needs of camellia oleifera planting.

[0003] Existing micro-sprinklers only have a single working mode and cannot flexibly adjust the irrigation method according to the water requirements of different growth stages such as the seedling stage and the mature stage of camellia oleifera. They also cannot meet the differentiated irrigation needs of the complex planting scenario in camellia oleifera plantations. In order to achieve precise irrigation for different crops and different growth stages of camellia oleifera, growers need to lay out multiple micro-sprinkler tapes of different specifications in the field, which not only increases the investment cost of irrigation equipment, but also increases the difficulty of field pipeline layout and subsequent maintenance.

[0004] Meanwhile, existing micro-sprinklers lack an effective closure structure. When not in operation, the water outlet channel of the sprinkler is open, and impurities such as gravel and soil in the field can easily enter the sprinkler, causing blockage and resulting in uneven irrigation or even no water output, which seriously affects the irrigation effect of camellia oleifera. Furthermore, the existing micro-sprinkler irrigation system does not have appropriate filtration and protection measures for impurities in the irrigation water, which further aggravates the blockage problem of micro-sprinklers and increases the management cost and maintenance workload of camellia oleifera planting.

[0005] In summary, existing micro-sprinkler irrigation equipment suffers from core problems such as limited modes, poor adaptability, and susceptibility to clogging. These issues prevent it from meeting the irrigation needs of large-scale and precise Camellia oleifera cultivation. There is an urgent need to develop a micro-sprinkler device that can flexibly switch working modes and has an anti-clogging structure to adapt to the irrigation needs of different growth cycles and complex planting scenarios of Camellia oleifera, thereby improving the efficiency and precision of irrigation for Camellia oleifera cultivation. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide an anti-clogging micro-spraying device.

[0007] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: an anti-clogging micro-spraying device, comprising a water storage tank, a water outlet pipe, micro-spraying pipes, and spray nozzles. The water storage tank is equipped with a filtration mechanism and a mixing mechanism. A water inlet chamber is provided on the inner side of the top of the water storage tank. The filtration mechanism is located in the water inlet chamber, and the mixing mechanism is located on the outer side of the water storage tank. An adjustable booster pump is provided at the bottom of the water storage tank. The inlet end of the adjustable booster pump is connected to the water outlet at the bottom of the water storage tank through a pipe, and the outlet end of the adjustable booster pump is connected to one end of the water outlet pipe. A water pressure monitor is provided on the water outlet pipe, and the other end of the water outlet pipe is connected to multiple micro-spraying pipes. At least three groups of micro-spraying pipes are provided, and different types of spray nozzles are provided on different groups of micro-spraying pipes. Multiple spray nozzles are spaced apart on each group of micro-spraying pipes. The output water pressure is adjusted by the adjustable booster pump, and combined with the real-time monitoring data of the water pressure monitor, the different groups of spray nozzles are controlled to switch to drip irrigation mode, micro-spraying mode, or off mode respectively.

[0008] As an improvement: the nozzle includes a housing, a clamping plate is threaded to the bottom of the housing, a water inlet pipe is threaded to the bottom of the clamping plate, the water inlet pipe is located inside the hole on the micro-spray tube, the clamping plate and the water inlet pipe clamp the micro-spray tube, and a cap is threaded to the top of the housing, on which micro-spray heads are symmetrically arranged.

[0009] As an improvement: the inner side of the shell is symmetrically provided with side plates, and a water inlet slide cavity is formed between the two side plates. The inner side of the shell is provided with a movable plate, and the bottom sides of the movable plate are provided with wing plates. The wing plates are slidably disposed in the water inlet slide cavity. The shell and the wing plates are respectively provided with drip irrigation hole one and drip irrigation hole two. The top of the movable plate is provided with a spring, and the top of the spring is connected to the cover.

[0010] As an improvement: The top of the movable plate is provided with a connecting rod, and the top of the connecting rod passes through the through hole at the top of the cover and is threaded to a pressure cap. An outer plug is provided on the outside of the pressure cap, and a receiving groove is provided on the top of the cover. The pressure cap and the outer plug are located in the receiving groove. The micro nozzle is located in the through hole of the receiving groove and the outer plug presses down on the outer end of the micro nozzle. Inner plugs are provided on both sides of the top of the movable plate. After the movable plate moves up, the inner plugs seal the inner end of the micro nozzle.

[0011] As an improvement: the drip irrigation hole one and drip irrigation hole two are staggered. After water is introduced into the micro-sprinkler, the movable plate moves up, and drip irrigation hole one and drip irrigation hole two are aligned and enter the drip irrigation mode. At this time, the movable plate is in the water inlet slide cavity, which is blocked. After the water pressure increases, the movable plate moves up, drip irrigation hole one and drip irrigation hole two are staggered, and the bottom of the movable plate is higher than the side plate. The micro-sprinkler head is connected to the water inlet pipe head through the inner cavity of the shell and enters the micro-sprinkler mode. After the water pressure increases again, the movable plate moves up until the inner plug plate blocks the inner end of the micro-sprinkler head and enters the closed mode.

[0012] As an improvement: the filtration mechanism includes a filter box, which is inserted into the water inlet chamber through the external through hole of the water storage tank. The filter box is provided with a first filter layer and a second filter layer. A filter screen is provided at the bottom of the filter box, and a protective cover is hinged at the water inlet hole at the top of the water inlet chamber.

[0013] As an improvement: the mixing mechanism includes an agitation chamber fixed to the outside of the water storage tank, the inner cavity of the agitation chamber is connected to the inside of the water storage tank, a motor is provided on the top of the agitation chamber, a rotating shaft is provided at the output end of the motor, the rotating shaft is rotatably located in the inner cavity of the agitation chamber, and a spiral blade is provided on the rotating shaft.

[0014] The advantages of this invention compared to existing technologies are as follows: This invention integrates filtration, water-fertilizer mixing, water pressure regulation, and multi-mode irrigation functions, fundamentally solving the problems of clogging, single mode, and unstable water pressure in camellia oil irrigation. It significantly improves irrigation accuracy and water-fertilizer utilization, adapts to the irrigation needs of different growth stages of camellia oil, and reduces planting and management costs. Furthermore, the device has a simple structure, is easy to operate, and is easy to install and maintain, making it suitable for large-scale application in camellia oil plantations. Specifically: 1. The sprinkler head automatically switches between three modes: drip irrigation, micro-spraying, and off, based on water pressure changes. With multiple sets of micro-spray pipes of different models of sprinkler head, the irrigation mode and range can be precisely adjusted according to the water requirements of different growth stages of camellia seedlings and mature plants. The drip irrigation mode meets the precise water replenishment needs of camellia seedlings, while the micro-spraying mode achieves large-area uniform irrigation for mature plants, improving the targeted nature of irrigation. 2. The adjustable booster pump, together with the water pressure monitor, forms a closed-loop control system, which can monitor and precisely adjust the pipeline water pressure in real time, avoiding uneven irrigation caused by excessively high or low water pressure. At the same time, by controlling the mode switching of different groups of sprinklers through water pressure, it can achieve zoned and precise irrigation of the camellia plantation, meeting the growth needs of camellia in different areas. 3. The filtration mechanism adopts a multi-layer filtration structure of filter layer one, filter layer two and filter screen, which can effectively intercept impurities in irrigation water and prevent impurities from entering the pipeline and nozzle and causing blockage. At the same time, the filter box adopts a plug-in design, which is easy to disassemble and clean, reduces the difficulty of device maintenance, and ensures the smooth flow of camellia oil irrigation pipeline and nozzle from the source. 4. The mixing mechanism is driven by a motor to rotate the shaft and spiral blades, which can quickly and evenly mix water with fertilizers, pesticides, etc., to achieve integrated water and fertilizer irrigation. This allows the roots of the camellia to absorb nutrients and water evenly, solving the problems of uneven mixing and nutrient waste in traditional manual methods, greatly improving water and fertilizer utilization, and promoting uniform growth of camellia.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 6As shown, an anti-clogging micro-spray device includes a water storage tank 1, a water outlet pipe 5, a micro-spray pipe 6, and a nozzle 7. The water storage tank 1 is equipped with a filter mechanism 2 and a mixing mechanism 3. An inlet chamber 11 is located on the inner side of the top of the water storage tank 1, with the filter mechanism 2 located inside the inlet chamber 11 and the mixing mechanism 3 located on the outer side of the water storage tank 1. An adjustable booster pump 4 is located at the bottom of the water storage tank 1. The inlet of the adjustable booster pump 4 is connected to the outlet of the bottom of the water storage tank 1 via a pipe. One end of the water outlet pipe 5 is connected to the water outlet pipe 5; a water pressure monitor 53 is installed on the water outlet pipe 5, and the other end of the water outlet pipe 5 is connected to multiple micro-sprinkler pipes 6; at least three sets of micro-sprinkler pipes 6 are set, and the nozzles 7 on different sets of micro-sprinkler pipes 6 are of different models, and multiple nozzles 7 are set at intervals on each set of micro-sprinkler pipes 6; the output water pressure is adjusted by the adjustable booster pump 4, and combined with the real-time monitoring data of the water pressure monitor 53, the different sets of nozzles 7 are controlled to switch to drip irrigation mode, micro-sprinkler mode or off mode respectively.

[0030] This anti-clogging micro-sprinkler device addresses the problems of existing agricultural irrigation equipment in practical applications, such as impurities in irrigation water causing clogging of pipes and nozzles, a single irrigation mode that cannot adapt to the water requirements of different crop growth stages, poor irrigation uniformity due to lack of real-time monitoring and precise control of water pressure, low and uneven water and fertilizer mixing efficiency, and difficulty in achieving zoned precision irrigation due to the lack of differentiated nozzle configuration. It effectively solves the technical pain points of traditional irrigation devices, such as poor anti-clogging effect, low irrigation accuracy, and insufficient adaptability, and meets the needs of precision irrigation and water and fertilizer integration for large-scale crop planting.

[0031] This device uses a water storage tank 1 as its core, serving as both a water storage and fertilizer mixing carrier. Irrigation water first enters the inlet chamber 11 at the top of the tank, where a built-in filter mechanism 2 filters out impurities, preventing them from entering subsequent pipes and nozzles 7 and causing blockages. The mixing mechanism 3 on the outside of the tank 1 ensures uniform mixing of water, fertilizer, and pesticides, achieving integrated water and fertilizer supply. An adjustable booster pump 4 at the bottom of the tank 1 pumps the treated fertilizer solution into the outlet pipe 5. A water pressure monitor 53 on the outlet pipe 5 collects real-time water pressure data, allowing operators to precisely adjust the adjustable pump based on this data. The booster pump 4 outputs water pressure; at least three sets of micro-sprinklers 6 connected to the water outlet pipe 5 are equipped with different types of nozzles 7. By utilizing the regulation effect of water pressure changes and combining the water pressure adaptability of different sets of micro-sprinklers 6, different sets of nozzles 7 can be switched to drip irrigation mode, micro-sprinkler mode or off mode respectively. At the same time, multiple nozzles 7 spaced apart on each set of micro-sprinklers 6 can ensure the uniformity of irrigation coverage. Finally, through filtration, water and fertilizer mixing, precise water pressure monitoring and adjustment, and the differentiated configuration of multiple types of nozzles 7, zoned, precise, multi-mode integrated irrigation of crop planting can be achieved.

[0032] Combined with appendix Figure 6 Appendix Figure 7 and attached Figure 8As shown, the nozzle 7 includes a housing 71, a clamping plate 72 is threaded to the bottom of the housing 71, and a water inlet pipe head 73 is threaded to the bottom of the clamping plate 72. The water inlet pipe head 73 is located inside the hole on the micro-spray tube 6. The clamping plate 72 and the water inlet pipe head 73 clamp the micro-spray tube 6. A cap 76 is threaded to the top of the housing 71, and micro-spray heads 77 are symmetrically arranged on the cap 76.

[0033] Combined with appendix Figure 8 Appendix Figure 9 Appendix Figure 10 and attached Figure 11 As shown, the inner side of the housing 71 is symmetrically provided with side plates 711, and a water inlet slide cavity 712 is formed between the two side plates 711. The inner side of the housing 71 is provided with a movable plate 74, and the bottom sides of the movable plate 74 are provided with wing plates 741. The wing plates 741 are slidably disposed in the water inlet slide cavity 712. The housing 71 and the wing plates 741 are respectively provided with a drip irrigation hole 1 713 and a drip irrigation hole 2 742. The top of the movable plate 74 is provided with a spring 75, and the top of the spring 75 is connected to the cover 76.

[0034] The sprinkler head 7, relying on the cooperation between the housing 71 and the internal movable structure, switches between different irrigation modes by means of water pressure changes. The entire unit is fixed by the threaded engagement of the inlet pipe head 73 and the clamping plate 72, clamping the micro-sprinkler tube 6. The cap 76 on the top of the housing 71 provides protection for the internal components and houses symmetrically arranged micro-sprinkler heads 77. The two side plates 711 inside the housing 71 form an inlet sliding cavity 712. The movable plate 74 is slidably disposed in this inlet sliding cavity 712 via a bottom wing plate 741, and the top of the movable plate 74 is supported by a spring 75 connected to the cap 76 for return. The drip irrigation holes 713 and 742 on the housing 71 and wing plate 741 provide channels for drip irrigation water output. After the water and fertilizer solution in the micro-sprinkler 6 enters the interior of the sprinkler head 7 through the water inlet head 73, the water pressure will push the movable plate 74 to slide up and down in the water inlet slide cavity 712. By changing the on / off state of the drip irrigation holes and opening the communication path between the inner cavity of the housing 71 and the micro-sprinkler head 77, the switching between different modes of drip irrigation and micro-sprinkler irrigation can be realized. The whole process relies on the natural change of water pressure to drive the internal structure to move, and with the reset action of the spring 75, the water output mode of the sprinkler head 7 can be autonomously adjusted.

[0035] Combined with appendix Figure 8 Appendix Figure 9 Appendix Figure 10 and attached Figure 12As shown, the top of the movable plate 74 is provided with a connecting rod 743, and the center through hole of the cover 76 is provided with a sealing ring 762. The top of the connecting rod 743 passes through the sealing ring 762 and is threaded to a pressure cap 78. An outer blocking platform 781 is provided on the outside of the pressure cap 78. The top of the cover 76 is provided with a receiving groove 761. The pressure cap 78 and the outer blocking platform 781 are located in the receiving groove 761. The micro-nozzle 77 is located in the through hole of the receiving groove 761 and the outer blocking platform 781 presses down on the outer end of the micro-nozzle 77. The top two sides of the movable plate 74 are provided with inner blocking plates 744. After the movable plate 74 moves upward, the inner blocking plates 744 seal the inner end of the micro-nozzle 77.

[0036] Combined with appendix Figure 8 Appendix Figure 9 and attached Figure 10 As shown, the drip irrigation hole 1 713 and drip irrigation hole 2 742 are misaligned. After water is introduced into the micro-sprinkler 6, the movable plate 74 moves upward, and the drip irrigation hole 1 713 and drip irrigation hole 2 742 are aligned and enter the drip irrigation mode. At this time, the movable plate 74 is in the water inlet slide cavity 712, which is blocked. After the water pressure increases, the movable plate 74 moves upward, and the drip irrigation hole 1 713 and drip irrigation hole 2 742 are misaligned. The bottom of the movable plate 74 is higher than the side plate 711. The micro-sprinkler head 77 is connected to the water inlet pipe head 73 through the inner cavity of the housing 71 and enters the micro-sprinkler mode. After the water pressure increases again, the movable plate 74 moves upward until the inner blocking plate 744 blocks the inner end of the micro-sprinkler head 77 and enters the closed mode.

[0037] The sprinkler head 7 is driven by water pressure changes and, in conjunction with the internal sliding and sealing structure, achieves autonomous switching between drip irrigation, micro-spraying, and shut-off modes. Initially, the outer sealing platform 781 of the pressure cap 78 presses down on the outer end of the micro-sprayer head 77 within the receiving groove 761. The drip irrigation holes 713 and 742 on the housing 71 and wing plate 741 are misaligned, completely blocking the liquid outflow channel and preventing sand and gravel from entering and causing blockages. After water flows through the micro-spray pipe 6, the water pressure pushes the movable plate 74 upwards, aligning drip irrigation hole 713 with drip irrigation hole 742. At this time, the movable plate 74 seals the inlet sliding cavity 712, and the fertilizer solution flows out through the aligned drip irrigation holes, and the sprinkler head 7 enters drip irrigation mode. When the water pressure in the pipeline increases, the movable plate 74 continues to operate under greater water pressure. As the water pressure increases, drip irrigation hole 1 713 and drip irrigation hole 2 742 are misaligned again. The bottom of the wing plate 741 will block drip irrigation hole 1 713. After the movable plate 74 rises, its bottom is higher than the side plate 711. The blockage at the top of the water inlet slide cavity 712 is released, and the water and fertilizer solution enters the inner cavity of the shell 71 and is sprayed out through the micro-sprinkler 77. The sprinkler 7 switches to micro-sprinkler mode. When the water pressure increases further, the movable plate 74 continues to move upward until the inner blocking plate 744 blocks the inner end of the micro-sprinkler 77. The water inlet channel of the micro-sprinkler 77 is blocked. At this time, drip irrigation hole 1 713 is blocked by the lower edge of the wing plate 741, and the sprinkler 7 enters the closed mode. The sprinkler 7 relies on the change of water pressure gradient to drive the movable plate 74 to slide. Combined with the reset action of the spring 75, the precise switching and stable operation of the three modes are achieved.

[0038] The working mode switching of the sprinkler head 7 is achieved by controlling water pressure changes. By setting different groups of micro-sprinklers 6, and the different models of sprinkler heads 7 on the different groups of micro-sprinklers 6, different models of sprinkler heads 7 can work in different modes under the same water pressure. This can effectively control the irrigation methods of crops in different areas. This method can be used for crops with different growth cycles, and can also be used for differentiated irrigation of mixed crops. For example, if the micro-sprinklers 6 are hung on camellia trees, and medicinal herbs, legumes, etc. are planted under the camellia trees, the drip irrigation mode is suitable for irrigating these crops and the roots of the camellia trees, while the micro-sprinkler mode will spray the water and fertilizer solution onto the leaves and fruits of the camellia trees, forming a compound irrigation. In addition, the shut-off mode of the sprinkler head 7 under high water pressure can effectively control the irrigation volume and prevent the high-pressure water flow from washing away the leaves and fruits.

[0039] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 6 As shown, the adjustable booster pump 4 is a variable frequency booster pump, fixed at the bottom of the water storage tank 1. The water inlet of the adjustable booster pump 4 is connected to the water storage tank 1 through a pipe. The water outlet of the adjustable booster pump 4 is connected to the water outlet pipe 5 by a connecting pipe 51. The connecting pipe 51 is equipped with a water pressure monitor 53, a control valve 52 and a flow sensor. The water pressure monitor 53 is a pressure transmitter and the flow sensor is an electromagnetic flow sensor, which monitors the water pressure and flow data in the main water outlet pipe 5 in real time.

[0040] Combined with appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the filtration mechanism 2 includes a filter box 21, which is inserted into the water inlet chamber 11 through the external through hole of the water storage tank 1. The filter box 21 is provided with a first filter layer 22 and a second filter layer 23, which are respectively a quartz sand filter layer and an activated carbon filter layer, and are fixed in sequence in the filter box 21 along the water flow direction. The bottom of the filter box 21 is provided with a filter screen 24, which has a pore size of 50-100 mesh, smaller than the pore size of the first filter layer 22 and the second filter layer 23. A protective cover 12 is hinged at the water inlet hole at the top of the water inlet chamber 11. The bottom of the water storage tank 1 is provided with a drain pipe 14, and a drain valve 15 is provided on the drain pipe 14.

[0041] The filtration mechanism 2 achieves multi-layer, step-by-step filtration of irrigation water. The protective cover 12 prevents external impurities from falling into the water inlet hole at the top of the inlet chamber 11. After entering the inlet chamber 11, the irrigation water first flows through the quartz sand filter layer (filter layer 1 22) and the activated carbon filter layer (filter layer 23) arranged along the water flow direction in the filter box 21, thereby completing the filtration and adsorption purification of large particles in the water. After double-layer filtration, the water passes through the filter screen 24 to further intercept fine impurities, completing the deep filtration of the irrigation water and effectively preventing various impurities from entering the subsequent pipelines and nozzles 7 and causing blockages. The filter box 21 can be completely pulled out from the external through hole of the water storage tank 1 for easy cleaning and replacement of the internal filter layer. The drain pipe 14 at the bottom of the water storage tank 1 works with the drain valve 15 to periodically discharge the impurities deposited at the bottom of the water storage tank 1 after filtration, ensuring the continuous filtration effect of the filtration mechanism 2 and the cleanliness of the inside of the water storage tank 1.

[0042] Combined with appendix Figure 3 and attached Figure 5 As shown, the mixing mechanism 3 includes an agitation chamber 31 fixed to the outside of the water storage tank 1. The agitation chamber 31 is provided with a flow guide cavity 32. The upper and lower ends of the flow guide cavity 32 are respectively provided with an outlet 34 and an inlet 33 communicating with the water storage tank 1. The inlet 33 is located below the liquid surface, and the outlet 34 is located above the liquid surface. The water storage tank 1 is provided with a water level detector 13. The top of the agitation chamber 31 is provided with a motor 35. The output end of the motor 35 is provided with a rotating shaft 36. The rotating shaft 36 is rotatably located in the flow guide cavity 32. The rotating shaft 36 is provided with a spiral blade 37. The top of the water storage tank 1 is provided with a dosing port 16.

[0043] The mixing mechanism 3 relies on the connection structure between the stirring chamber 31 and the water storage tank 1, and with the stirring and guiding of the spiral blades 37, achieves efficient and uniform mixing of water and fertilizer, and water and pesticide. The dosing port 16 at the top of the water storage tank 1 can add fertilizer or pesticide. The water level detector 13 in the water storage tank 1 monitors the water level in real time. The guiding cavity 32 of the stirring chamber 31 is connected to the water storage tank 1 through the inlet 33 at the bottom below the liquid surface, and the top is connected to the water storage tank 1 through the outlet 34 at the top above the liquid surface to form a circulation path. After the motor 35 is started, it drives the rotating shaft 36 to drive the spiral blades 37 to rotate in the guiding cavity 32. With the help of the swirling effect of the spiral blades 37, the water in the water storage tank 1 is drawn into the guiding cavity 32 from the inlet 33, so that the water inside the water storage tank 1 forms a circulating flow state. Through continuous water circulation and stirring, the water and fertilizer and water and pesticide in the water storage tank 1 are uniformly mixed throughout, ensuring the uniform supply of nutrients or pesticides during subsequent irrigation.

[0044] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
