[0002] Traditional flood irrigation methods have many problems in greenhouse cultivation, such as high water waste (utilization rate less than 50%), significant risks of soil compaction and salinization, susceptibility to diseases, and uncontrollable humidity. To address these issues, greenhouses are beginning to adopt micro-sprinkler irrigation technology. For example, Chinese utility model patent CN111316887A discloses a micro-sprinkler irrigation device, specifically comprising a sprinkler, a water supply branch pipe, and a capillary tube. The top of the high-strength micro-tube is connected to the sprinkler, and the bottom is connected to a hollow conversion pin. The upper part of the conversion pin is connected to one end of the capillary tube, and the other end of the capillary tube is connected to the water supply branch pipe. This invention features simple structure, long service life, and stable reliability.

[0003] However, when adjusting the height of the micro-spraying device, the operator needs to adjust the height of each micro-spraying device one by one, which is labor-intensive and inefficient. Summary of the Invention

[0004] Based on this, this application provides an adjustable micro-sprinkler irrigation system for greenhouses to solve the problem that when adjusting the height of the micro-sprinkler devices, operators need to adjust the height of each micro-sprinkler device one by one, which is labor-intensive and inefficient.

[0005] The technical solution to the above-mentioned technical problems in this application is as follows:

[0006] An adjustable micro-sprinkler irrigation system for greenhouses includes: a support assembly, an adjustment mechanism, and a control assembly. The support assembly includes a support rod and a ground pin, the ground pin being detachably connected to the support rod, and a fixing plate being fitted onto the ground pin. A fixing opening is provided at the top of the fixing plate, and a ground nail is detachably connected to the fixing opening for fixing the support assembly. The adjustment mechanism includes a rotating head and an electrically controlled telescopic rod. The rotating head is detachably connected to the end of the support rod away from the fixing plate. One end of the electrically controlled telescopic rod is rotatably connected to the rotating head, and the other end is provided with an atomizing nozzle. The spray angle of the atomizing nozzle is adjustable 360° via a rotating tube.

The water pump is connected to the water tank via an inlet pipe, and a liquid supply pipe is connected to the outlet of the water pump. The liquid supply pipe is wound around the winding component, which is used to wind and unwind the liquid supply pipe. The liquid supply pipe is detachably connected to the atomizing nozzle via a water inlet pipe. The water pump is electrically connected to the control assembly.

[0008] Preferably, the water inlet pipe includes an inlet section, an outlet section, and a corrugated tension section. The inlet section is connected to the liquid supply pipe, and the inlet section is detachably connected to the fixed end of the electrically controlled telescopic rod near the corrugated tension section. The outlet section is connected to the atomizing nozzle, and the outlet section is detachably connected to the telescopic end of the electrically controlled telescopic rod near the corrugated telescopic section. The corrugated tension section can extend and retract under the action of the electrically controlled telescopic rod.

[0009] Preferably, the fixed end of the electrically controlled telescopic rod is provided with a sleeve, the water outlet part passes through the sleeve and is connected to the atomizing nozzle, the corrugated stretching part is placed inside the sleeve, and the length of the sleeve is not less than the limit stretching length of the corrugated stretching part.

[0017] 2. By controlling the height of the atomizing nozzle through an electrically controlled telescopic rod, the spraying range can be changed. At the same time, the spraying height can be adjusted according to the growth height of the crop, solving the problem of non-adjustable height that is difficult to adapt to the needs of different crop growth stages.

[0033] Please see Figures 1 to 8This application provides an adjustable micro-sprinkler irrigation system for greenhouses, comprising: a support assembly 100, an adjustment mechanism 200, and a control assembly 300. The support assembly 100 includes a support rod 110 and a ground pin 120. The ground pin 120 is detachably connected to the support rod 110, and a fixing plate 121 is sleeved on the ground pin 120. A fixing opening 122 is formed at the top of the fixing plate 121, and a ground nail 123 is detachably connected to the fixing opening 122. The ground nail 123 is used to fix the support assembly 100. The adjustment mechanism 200 includes a rotating head 210 and an electrically controlled telescopic rod 220. The rotating head 210 is detachably connected to the end of the support rod 110 away from the fixed plate 121. One end of the electrically controlled telescopic rod 220 is rotatably connected to the rotating head 210, and the other end is provided with an atomizing nozzle 225. The spray angle of the atomizing nozzle 225 is adjustable 360° through a rotating tube. The control component 300 is electrically connected to the electrically controlled telescopic rod 220 and is used to control the extension and retraction of the electrically controlled telescopic rod 220.

[0034] Specifically, several support components 100 are provided. Support rods 110 are made of, but are not limited to, cylinders or square tubes, and both ends of the support rods 110 are threaded. Ground needles 120 have a thread at one end that matches the thread of the support rods 110 (if the support rod 110 has an external thread, then the ground needle 120 has an internal thread, and they are mutually compatible; conversely, if the support rod 110 has an internal thread, then the ground needle 120 has an external thread, allowing for detachable connection via the threads). The other end of the ground needle 120 is tapered for insertion into the soil. The surface of 120 is provided with a threaded groove (external thread). The fixing plate 121 is disc-shaped and has a through hole at the circular part. The through hole is threaded and the thread of the fixing plate 121 matches the threaded groove on the surface of the ground nail 120. By rotating the fixing plate 121, the distance between the fixing plate 121 and the soil surface is changed. Several fixing holes 122 are provided on the fixing plate 121. The fixing holes 122 are evenly distributed around the through hole. One end of the ground nail 123 passes through the fixing hole 122 and is inserted into the soil for fixing.

[0035] The rotating head 210 includes a base 211, a first motor 212, a first bearing 213, and a connecting block 214. A connecting rod is provided at the bottom of the base 211, and the connecting rod is provided with a thread that matches the support rod 110 (similarly, if the support rod 110 is internally threaded, the connecting rod is externally threaded; conversely, if the support rod 110 is externally threaded, the connecting rod is internally threaded). The first motor 212 is located inside the base 211. The first bearing 213 is a waterproof bearing and is fitted onto the end of the base 211 away from the connecting rod. The outer shaft of the first bearing 213 is detachably connected to the side wall of the base 211. The rotating shaft of the first motor 212 is connected to the inner shaft of the first bearing 213 and extends out of the first bearing 213 away from the connecting rod, and is connected to the connecting block 214. The connecting block is connected to the electrically controlled telescopic rod 220 by a thread. The outer shaft of the first bearing 213 is provided with a threaded hole, and the outer side of the base 211 is provided with a round hole, which corresponds to the threaded hole. The first bearing 213 and the base 211 are detachably connected by bolts. Waterproof sponge is provided on the periphery of the outer shaft of the first bearing 213 to prevent water from entering the motor from the connection between the first bearing 213 and the base 211. The first motor 212 is electrically connected to the control component 300.

[0036] The fixed end 222 of the electrically controlled telescopic rod 220 is connected to the connecting block 214, and the telescopic end 223 of the electrically controlled telescopic rod 220 is connected to the atomizing nozzle 225. The electrically controlled telescopic rod 220 uses a cylinder, hydraulic cylinder, etc., preferably a mechanical type. For example, the electrically controlled telescopic rod 220 includes a second motor 221, a fixed end 222, a telescopic end 223, and a second bearing 224. An auxiliary plate and a threaded sleeve are provided inside the fixed end 222. The auxiliary plate is fixedly connected to the inner wall of the fixed end 222. The second motor 221... The fixed end of 21 is connected to an auxiliary plate, and the shaft extension end of the second motor 221 is connected to a threaded rod 227, which passes through a threaded sleeve. One end of the threaded rod 227 away from the second motor 221 is threadedly connected to the inner shaft of the second bearing 224, and one end of the threaded rod 227 extends out of the second bearing 224 and into the telescopic end 223. The length of the threaded rod 227 is not less than the telescopic distance of the telescopic end 223. The outer shaft of the second bearing 224 is fixedly connected to the inner wall of the telescopic end 223. The threaded sleeve is used to limit the sliding distance of the second bearing 224 and prevent the second bearing 224 from contacting the second motor 221. To solve the problem of the telescopic end 223 of the electrically controlled telescopic rod 220 rotating on its own, positioning blocks are provided on both sides of the telescopic end 223 of the electrically controlled telescopic rod 220, and a positioning groove is provided on the inner wall of the fixed end 222 of the electrically controlled telescopic rod 220. The positioning groove slides and the positioning blocks are in a limiting fit.

[0037] Further, the operator enters the greenhouse and connects the ground pin 120, support rod 110, rotating head 210, electrically controlled telescopic rod 220, and atomizing nozzle 225 in sequence. After connection, the fixing plate 121 is rotated so that it is positioned at the end of the ground pin 120 closest to the rotating head 210. After inserting the ground pin 120 into the soil, the fixing plate 121 is rotated in the opposite direction to actually move closer to the ground until the fixing plate 121 contacts the ground and stops (if the rotating plate is too close to the ground and cannot rotate easily, the fixing plate 121 is stepped on directly to make the ground pin 120 insert deeper into the ground until the rotating plate contacts the ground). Then, the ground nail 123 is inserted into the soil through the fixing port 122. Finally, the atomizing nozzle 225 is connected to the water source; the steps are repeated until all installations are completed. The operator controls the control component 300, which is located in an easily accessible position, to activate the second motor 221 inside the electrically controlled telescopic rod 220. The second motor 221 drives the threaded rod 227 to rotate, causing the second bearing 224, which is threaded to it, to slide up or down along the inner wall of the fixed end 222, thereby causing the telescopic end 223 to rise or fall. After reaching the preset height, the operator turns off the second motor 221 and then turns on the water source and the first motor 212. The rotation of the first motor 212 drives the connecting block 214 and the rotating head 210 fixedly connected to the connecting block 214 to rotate, thereby driving the electrically controlled telescopic rod 220 to rotate. The atomizing nozzle 225 connected to the electrically controlled telescopic rod 220 rotates accordingly, allowing water to be sprayed in 360°.

[0038] Furthermore, the second motor 221 of each electrically controlled telescopic rod 220 is connected to the control component 300. The operator can adjust the second motor 221 at different positions according to the humidity in the greenhouse, so that the height of the atomizing nozzle 225 at different positions is different, thus solving the problem of humidity gradient in the greenhouse.

[0039] The technical solution of the adjustable micro-sprinkler irrigation system for greenhouses adopted in this application can achieve the following beneficial effects:

[0040] 1. By setting up a control component 300, the operator can control the electrically controlled telescopic rod 220 that is electrically connected to it through the control component 300, thereby adjusting its height, which solves the problem of high labor intensity and low work efficiency of the operator opening the electrically controlled telescopic rod 220 one by one.

[0041] 2. The height of the atomizing nozzle 225 is controlled by the electrically controlled telescopic rod 220, thereby changing the spraying range. At the same time, the spraying height can be adjusted according to the growth height of the crop, solving the problem that the height is not adjustable and it is difficult to adapt to the needs of different crop growth stages.

[0042] 3. By setting a fixing plate 121 on the ground needle 120, the problem of the ground soil becoming soft and the device easily tipping over due to long-term irrigation is solved.

[0043] 4. By setting up micro-sprinkler irrigation, the problem of soil compaction and salinization risks caused by long-term flood irrigation can be solved.

[0044] 5. By using a single control, the height of the atomizing nozzles 225 at different locations can be made different, thus solving the problem of humidity gradients caused by factors such as light and ventilation in the greenhouse.

[0045] Based on the above solution, this application also includes a liquid supply assembly 400, which includes a water tank 410, a water pump 420, and a winding member 430. The water pump 420 is connected to the water tank 410 through an inlet pipe 421, and a liquid supply pipe 440 is connected to the outlet of the water pump 420. The liquid supply pipe 440 is wound around the winding member 430, which is used to wind up and unwind the liquid supply pipe 440. The liquid supply pipe 440 is detachably connected to the atomizing nozzle 225 through a water inlet pipe 450. The water pump 420 is electrically connected to the control assembly 300.

[0046] Specifically, the water tank 410 is placed in a location where water can be easily added, such as near a ditch or near the greenhouse outlet. The water pump 420 is connected to the water tank 410 via an inlet pipe 421. A filter screen is installed at the outlet of the water tank 410 to prevent debris from falling into the water tank 410 from entering the inlet pipe 421. The outlet of the water pump 420 is connected to a supply pipe 440. The material selection for the supply pipe 440 must comprehensively consider corrosion resistance, flexibility, durability, cost, and food safety. For example, food-grade linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), and U-resistant polyethylene are suitable materials. V-shaped LLDPE pipes, food-grade silicone pipes, etc., are provided with several connection ports on the liquid supply pipe 440. The connection ports are connected to the water inlet of the atomizing nozzle 225 through the water inlet pipe 450. The winding component 430 is located at one end near the water pump 420 and has several threaded grooves. The liquid supply pipe 440 is wound around the winding component 430 along the threaded grooves. After the liquid supply pipe 440 is extended, at least one turn of the liquid supply pipe 440 is left on the winding component 430, and at most one layer of the liquid supply pipe 440 is left. The winding component 430 is made of, but is not limited to, a hand-cranked winding wheel 431, a motor winding wheel 431, etc.

[0047] Furthermore, in the initial state, the supply pipe 440 is completely wrapped around the take-up piece 430. The operator enters the greenhouse and pulls one end of the supply pipe 440 to unwrap the supply pipe 440 wrapped around the take-up piece 430 in a preset direction. After reaching the designated position, the operator uses detachable methods such as straps, ties, or pull rings to connect it to a fixed rod (cement pillar, wall, etc.) at the preset position and fixes the take-up piece 430 to prevent it from retracting automatically. Then, the operator connects the atomizing nozzle 225 to the connection port of the supply pipe 440 using the water inlet pipe 450. Conversely, when dismantling, the operator first removes the water inlet pipe 450 from the connection port, then removes the end of the supply pipe 440 away from the take-up piece 430, and then opens the take-up piece 430 to wind the supply pipe 440 onto the take-up wheel 431 for continued use next time. By setting up the winding component 430, the problem of high labor intensity and low recycling efficiency of manual recycling of the liquid supply pipe 440 is solved. At the same time, it also solves the problem that the liquid in the liquid supply pipe 440 does not flow out during manual recycling, which makes manual recycling difficult and easily causes coiling and knotting.

[0048] In one embodiment of this application, the water inlet pipe 450 includes a water inlet section 451, a water outlet section 453, and a corrugated tension section 452. The water inlet section 451 is connected to the liquid supply pipe 440, and the water inlet section 451 is detachably connected to the fixed end 222 of the electrically controlled telescopic rod 220 near the corrugated tension section 452. The water outlet section 453 is connected to the atomizing nozzle 225, and the water outlet section 453 is detachably connected to the telescopic end 223 of the electrically controlled telescopic rod 220 near the corrugated telescopic section. The corrugated tension section 452 can extend and retract under the action of the electrically controlled telescopic rod 220.

[0049] Specifically, the water inlet pipe 450 is a flexible hose, and its length is adjusted according to the distance from the liquid supply pipe 440 to the atomizing nozzle 225. The water inlet section 451 of the water inlet pipe 450 is the longest, and the length of the corrugated stretching section 452 is not less than the maximum extension length of the electrically controlled telescopic rod 220. The water outlet section 453 is a rigid pipe, and its length is the length from the atomizing nozzle 225 to the fixed end 222 of the electrically controlled telescopic rod 220. The two ends of the water outlet section 453 are detachably connected to the atomizing nozzle 225 and the telescopic end 223 of the electrically controlled telescopic rod 220 using a third bearing in conjunction with a binding strip or other means. For example, the inner shaft of the third bearing is connected to the telescopic end 223 of the electrically controlled telescopic rod 220, and the outer shaft of the third bearing is detachably connected to the water outlet section 453 using a binding strip or other means. Similarly, the water inlet section 451 and the fixed end 222 of the electrically controlled telescopic rod 220 are detachably connected using the same method (the connection is made using a fourth bearing). By setting the corrugated tension section 452, the problem of water inlet pipe 450 swinging back and forth when the electric telescopic rod 220 is extended and retracted is solved, which is prone to the problem of water leakage due to the connection falling off.

[0050] Based on the above scheme, the fixed end 222 of the electrically controlled telescopic rod 220 is provided with a sleeve 228. The water outlet 453 passes through the sleeve 228 and is connected to the atomizing nozzle 225. The corrugated stretching part 452 is placed inside the sleeve 228, and the length of the sleeve 228 is not less than the ultimate stretching length of the corrugated stretching part 452. The sleeve 228 is provided on the fourth bearing connecting the water inlet 451 and the fixed end 222. The diameter of the sleeve 228 is the same as the maximum diameter of the corrugated stretching part 452 when it is contracted. When the corrugated expansion joint contracts, it is entirely located within the sleeve 228, and part of the water outlet 453 is also located within the sleeve 228. When the corrugated expansion joint extends, the water outlet 453 located within the sleeve 228 is driven upward by the telescopic end 223 of the electrically controlled telescopic rod 220, thereby stretching the corrugated stretching part 452. Conversely, when it contracts, the corrugated expansion joint contracts. By setting the sleeve 228, the problem of the corrugated expansion joint swaying back and forth during contraction, which prevents it from contracting properly, is solved.

[0051] In another embodiment of this application, the fixing plate 121 is disc-shaped with guide grooves on its edge to disperse water flow and prevent soil erosion. The spray nozzles 226 of the atomizing nozzle 225 are arranged in an equidistant ring, and the spray nozzles 226 are detachable. When the circular structure is subjected to force in the soil, the pressure can be evenly diffused in all directions, avoiding local stress concentration; the radial guide grooves on the edge of the fixing plate 121 can effectively disperse the irrigation water flow, prevent water accumulation from eroding the soil, and reduce the impact of water backflow on the fixing plate 121. The detachable spray nozzles 226 solve the problem of different crops having different water requirements.

[0052] In another preferred embodiment of this application, the winding member 430 includes a winding wheel 431 and a spring 432, the spring 432 being disposed within the winding wheel 431, and the liquid supply pipe 440 being wound around the outside of the winding wheel 431. The winding member 430 also includes a shield 433, the shield 433 covering both sides of the winding wheel 431.

[0053] The outer side of the winding wheel 431 is provided with a guide groove for winding the liquid supply pipe 440. The winding wheel 431 is fixed by a support frame (both ends of the support are fixedly connected to the shield 433) on the side near the water pump 420. Both ends of the winding wheel 431 are covered by the shield 433, and the shield 433 is connected to the winding wheel 431 through a fifth bearing (the outer shaft of the fifth bearing is connected to the inner wall of the winding wheel 431, and the inner shaft of the fifth bearing is connected to the shield 433). A fixed shaft is provided between the two opposing shields 433. One end of the spring 432 is connected to the fixed shaft, and the other end is connected to the inner wall of the winding wheel 431. By setting the winding wheel 431 and the spring 432, the problems of high labor intensity and low work efficiency of manual winding are solved.

[0054] In another embodiment of this application, the control component 300 includes a control panel 310 and a humidity sensor 320. The control panel 310 is electrically connected to the water pump 420, the electrically controlled telescopic rod 220, and the humidity sensor 320, respectively. The humidity sensor 320 is used to detect the humidity in the greenhouse. Several humidity sensors 320 are provided, all of which are electrically connected to the control panel 310. The operator controls the first motor 212 and the second motor 221 at different positions by operating the control panel 310, making the operation simpler and more convenient.

[0055] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
