Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, specifically to an intelligent water-saving spray device for agricultural irrigation. Background Technology

[0002] Agricultural irrigation is an agricultural technology that uses artificial means to replenish water to farmland to meet the growth needs of crops. It is widely used in field planting, greenhouse fruits and vegetables, and nurseries. In my country, agricultural water use accounts for a high proportion of total water consumption, but water resources are unevenly distributed in time and space. Traditional irrigation methods suffer from problems such as flooding and low utilization rates, resulting in significant waste. Water-saving irrigation can reduce water consumption, lower agricultural production costs, alleviate the contradiction between water supply and demand, and prevent secondary soil salinization, thus ensuring sustainable agricultural development. Currently, the core regulating components of agricultural irrigation spray devices are mostly integrated structures, making disassembly and assembly cumbersome. This results in significant manpower and time consumption for cleaning internal flow channels, repairing faulty components, and replacing parts, leading to high maintenance costs. Furthermore, existing devices often rely on a single valve for atomization regulation, making it difficult to achieve precise droplet size matching. Therefore, it is necessary to propose an intelligent water-saving spray device for agricultural irrigation. Summary of the Invention

[0003] To address the problems in the prior art, this invention provides an intelligent water-saving spray device for agricultural irrigation.

[0004] The technical solution adopted by this invention to solve its technical problem is: an intelligent water-saving spray device for agricultural irrigation, comprising a support frame and a sprayer slidably engaged within the support frame. A pressure pump is installed at the bottom of the sprayer; The sprayer has a water guide pipe embedded in its inner end, which is connected to the output end of the pressure pump. An electromagnetic driver is installed on the top of the sprayer housing. An adjustment component is provided on the top of the water guide pipe. The adjustment component includes a connector one, a connector two, and a spray head, which are connected to the water guide pipe. An electromagnetic coil is embedded in the inner end of connector one and connector two, and the electromagnetic coil is electrically connected to the electromagnetic driver. A labyrinth channel block is provided on both sides of the inner end of connector one and connector two. A permanent magnet block is embedded in the inner end of the labyrinth channel block. An arc-shaped sealing damping block is fixedly connected to the end of the labyrinth channel block near and embedded in the inner wall of connector one and connector two. A female connector is provided on the mating surface of connector one. A groove is provided on the mating surface of connector two near connector one. A half-ring is slidably engaged in the inner end of the groove. A male connector is fixedly connected to the inner ring of the half-ring. A spring is fixedly connected between the half-ring and the groove.

[0005] Specifically, a fixing block is installed at the lower end of one of the support legs of the support frame, a plug rod is slidably engaged on the fixing block, a plug cylinder is fixedly connected to the bottom end of the plug rod, and a humidity sensor is installed in the groove on the outer wall of the plug cylinder.

[0006] Specifically, a support plate is sleeved on the lower end of the sprayer housing, and multiple different types of sensors are installed on the top of the support plate.

[0007] Specifically, a support ring is installed at the top of the support frame, and multiple cylinders are embedded in the support ring. The output end of the cylinder is fixedly connected to a lifting ring connected to the sprayer. Multiple limiting grooves are opened on the outer wall of the sprayer housing, and multiple sliders with diameters matching the limiting grooves are fixedly connected to the inner wall of the support ring.

[0008] Specifically, both the second connector and one end of the spray head are fixedly connected with threaded sleeves, and the first connector, the second connector, and the spray head are all connected by threaded sleeves.

[0009] Specifically, a sealing ring is fitted onto one end of each connector, near the threaded sleeve.

[0010] Specifically, the female connector and the male connector are electrically connected to the electromagnetic coil via connecting wires.

[0011] One of the beneficial effects of this invention is that, through the coordinated design of the support ring at the top of the support frame, the cylinder, the lifting ring, and the limiting guide structure, the lifting and lowering of the sprinkler is precisely controllable. The cylinder drives the lifting ring to smoothly slide the sprinkler along the axial direction of the support frame, and the guide cooperation between the slider and the limiting groove effectively constrains radial displacement, ensuring no swaying during the lifting process. This design allows for dynamic adjustment of the spraying height according to the crop canopy height, adapting to the irrigation needs of the entire growth period from seedling to mature plant, and avoiding uneven irrigation caused by a fixed spraying height.

[0012] The second beneficial effect of this invention is its innovative integrated design of detachable threaded connections and detachable electrical connections. The threaded sleeve allows for convenient assembly and disassembly of connector one and connector two. The male and female connectors automatically and precisely align under spring action, achieving circuit continuity without additional wiring. Simultaneously, the electromagnetic drive, combined with the magnetic field of the labyrinth channel blocks, enables stepless adjustment of the labyrinth channel spacing, flexibly changing the droplet size. This complements the flow control of pipeline valves, achieving intelligent water saving through controllable atomized water droplets. This structure ensures convenient component assembly and maintenance while achieving precise adaptation of the atomization effect, significantly improving water-saving efficiency and irrigation adaptability. It also extends the device's lifespan and reduces labor and maintenance costs for agricultural irrigation. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: An intelligent water-saving spray device for agricultural irrigation includes a support frame 1 and a sprayer 2 that is slidably engaged within the support frame 1. A pressure pump 21 is installed at the bottom of the sprayer 2. A fixing block 11 is installed at the bottom of one of the support legs of the support frame 1. An insert rod 12 is slidably engaged on the fixing block 11. An insert cylinder 13 is fixedly connected to the bottom of the insert rod 12. A humidity sensor 14 is installed in the groove on the outer wall of the insert cylinder 13. A support plate 22 is sleeved on the lower part of the outer shell of the sprayer 2. Multiple sensors 23 of different types are installed on the top of the support plate 22.

[0018] Among them, sensor 23 includes a temperature and humidity sensor, a light sensor and a wind speed sensor, which realizes the acquisition of multi-dimensional environmental parameters, and all of them are electrically connected to an external controller.

[0019] In use, the support frame 1 is unfolded and placed in the target irrigation area. The insertion rod 12, along with the insertion cylinder 13, is vertically inserted into the topsoil to stabilize the device. The pressure pump 21 is started, and the irrigation water is atomized and sprayed out by the sprinkler 2 after being pressurized, achieving uniform irrigation of the crops. During operation, the humidity sensor 14 installed on the outer wall of the insertion cylinder 13 collects soil moisture data in real time, and the multiple types of sensors 23 integrated on the support plate 22 simultaneously monitor environmental parameters, providing data support for the dynamic adjustment of irrigation strategies.

[0020] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a support ring 24 is installed at the top of the support frame 1, and multiple cylinders 25 are embedded in the support ring 24. The output end of the cylinder 25 is fixedly connected to a lifting ring 26 connected to the sprayer 2. Multiple limiting grooves 201 are opened on the outer wall of the sprayer 2 housing. Multiple sliders 240 with diameters matching the diameters of the limiting grooves 201 are fixedly connected to the inner ring wall of the support ring 24.

[0021] In use, after completing the device fixing and basic irrigation operations as described in Example 1, a control signal is input to the cylinder 25 embedded in the support ring 24 according to the different requirements of crop canopy height. This drives the piston rod of the cylinder 25 to extend and retract, thereby driving the lifting ring 26 to pull the sprinkler 2 up and down along the axial direction of the support frame 1. During the lifting process, the slider 240 on the inner ring wall of the support ring 24 and the limiting groove 201 on the outer wall of the sprinkler 2 housing form a sliding guide engagement, effectively constraining the radial displacement of the sprinkler 2, ensuring that its lifting process is smooth and without sway, and accurately matching the irrigation operation requirements of crops with different plant heights.

[0022] Example 3: The technical solution of this example, which differs from Example 1, includes: a water guide pipe 30 connected to the output end of the pressure pump 21 is embedded in the inner end of the sprayer 2; an electromagnetic actuator 31 is installed on the top of the sprayer 2 housing; an adjustment component 3 is provided at the top of the water guide pipe 30; the adjustment component 3 includes a connector 32, a connector 33, and a spray head 34 connected to the water guide pipe 30; an electromagnetic coil 310 is embedded in the inner end of the connector 32 and the connector 33, and the electromagnetic coil 310 is electrically connected to the electromagnetic actuator 31; a maze channel block 36 is provided on both sides of the inner end of the connector 32 and the connector 33; a permanent magnet block 360 is embedded in the inner end of the maze channel block 36; and the maze channel block 36 is close to and embedded in the inner wall of the connector 32 and the connector 33. An arc-shaped sealing damping block 361 is fixedly connected. A female connector 301 is provided on the mating surface of connector one 32. A groove 302 is provided on the mating surface of connector two 33 near connector one 32. A half ring 312 is slidably engaged at the inner end of the groove 302. A male connector 311 is fixedly connected to the inner ring of the half ring 312. A spring 313 is fixedly connected between the half ring 312 and the groove 302. A threaded sleeve 35 is fixedly connected to one end of connector two 33 and spray head 34. Connectors one 32, connector two 33 and spray head 34 are all threadedly connected by the threaded sleeve 35. A sealing ring 351 is fitted on one end of connector one 32 and connector two 33 near the threaded sleeve 35. The female connector 301 and the male connector 311 are electrically connected to the electromagnetic coil 310 through connecting wires.

[0023] Among them, the arc-shaped sealing damping block 361 is made of fluororubber, which has excellent sealing and anti-leakage performance, wear resistance and corrosion resistance.

[0024] In use, the first connector 32 and the second connector 33 are first detachably threaded together using the threaded sleeve 35. The sealing ring 351 at the connection point undergoes elastic deformation to ensure a leak-proof seal at the connection interface and prevent high-pressure water leakage. During the connection process, the spring 313 in the groove 302 releases its elastic energy, pushing the semi-ring 312 to slide along the groove, causing the male connector 311 to precisely align with the female connector 301 on the first connector 32. This achieves a detachable electrical connection between the electromagnetic coil 310 and the electromagnetic driver 31, enabling circuit conduction without additional wiring. After the device is started, the pressurized pump 21 pressurizes the water source and delivers it to the water pipe 30. The electromagnetic driver 31 regulates the current intensity of the input electromagnetic coil 310, causing the coil to generate a gradient magnetic field. This magnetic field interacts with the permanent magnet block 360 embedded in the labyrinth channel block 36, driving the labyrinth channel block 36 to slide along the inner walls of connector 1 32 and connector 2 33 (through the arc-shaped sealing damping block 361 embedded in the inner walls of connector 1 and connector 2). This allows for flexible changes in the spacing between the labyrinth channels, achieving stepless control of the effective flow cross section of the labyrinth flow channel. This, in turn, adjusts the water flow speed and swirling intensity, causing the spray head 34 to spray atomized water droplets with controllable particle size. Through the intelligent water-saving function of controllable atomized water droplets, it adapts to the irrigation needs of different crop growth stages. The arc-shaped sealing damping block 361 is always in close contact with the inner wall of the channel, ensuring the sealing during the dynamic adjustment of the flow channel and acting as a damping buffer to prevent the channel block from sliding too quickly and causing structural wear. When it is necessary to disassemble, maintain or replace parts, loosen the threaded sleeve 35 to separate connector 1 32 and connector 2 33. Under the action of tension, the male connector 311 separates from the female connector 301, and the circuit is disconnected simultaneously. This achieves simultaneous disassembly of electrical and mechanical connections, which is convenient to operate and does not damage the parts.
