Description

Technical Field

[0001] The present invention relates to the technical field of forage irrigation, and in particular to an intelligent irrigation device for forage breeding. Background Art

[0002] Forage grasses, a core grass species for grassland ecological restoration and animal husbandry development in northern my country, face stringent requirements for water resource management, soil improvement, and precision irrigation techniques. Traditional irrigation methods face several technical bottlenecks: First, their single function limits operational efficiency. Conventional irrigation equipment is limited to single-purpose water replenishment and cannot accommodate the complex demands of loosening soil, breaking up compacted soil, or nutrient infiltration. This results in field operations requiring the coordinated operation of multiple devices, significantly increasing labor and time costs. Second, maintenance is difficult. Soil particle adhesion to core components such as microneedles increases energy consumption and hinders subsequent soil breaking, necessitating frequent downtime, disassembly, and cleaning, and preventing functional adjustments based on actual conditions. Furthermore, water and fertilizer mixing systems commonly suffer from large pressure fluctuations and uneven mixing, which directly impact spray uniformity. Although some research has attempted to incorporate visual monitoring technology, existing solutions are often limited to single-parameter acquisition and fail to establish a multi-dimensional feedback loop, limiting the equipment's ability to make autonomous decisions in complex environments. For example, when detecting accumulation of deposits on the microneedle surface, traditional devices merely issue an alarm, requiring manual intervention to adjust the cleaning process.

[0003] Therefore, it is necessary to provide an intelligent irrigation device for pasture breeding to solve the above problems. Summary of the Invention

[0005] Preferably, a limiting cylinder is installed on the mobile device through a support plate, the limiting cylinder is sleeved on the outside of the rotating cylinder, and the support plate is slidably set on the mobile device; the bottom of the limiting cylinder has a dispersion nozzle corresponding to the nozzle, and the side of the limiting cylinder has a through hole corresponding to the nozzle, and the through hole is facing the direction of the microneedle.

[0006] Preferably, the spacing adjustment component includes: a base fixed to the mobile device, on which a slide driven by a telescopic rod is slidably provided, and the slide serves as a spacing adjustment end; when the nozzle rotates to the corresponding through-hole position, the spacing adjustment ends of the two spacing adjustment components are in a state of approaching each other; when the nozzle rotates to the corresponding dispersed nozzle, the spacing adjustment ends of the two spacing adjustment components are in a state of moving away from each other.

[0007] Preferably, the microneedle is connected to the rotating shaft via a thread, and the length of the microneedle is configured such that when the mobile device is placed on the ground, the microneedle can extend to a predetermined ground depth.

[0008] Preferably, the central chamber of the first bearing seat is rotatably connected to a supply pipe through a sealed bearing, one end of the supply pipe is connected to the rotating drum, and the other end is connected to the first tube body through a rotatable joint; the first bearing seat is also embedded with a second tube body, and the second tube body is connected to the supply pipe through a flexible tube.

[0009] Preferably, the supply pipe is formed of a contraction portion, a straight portion, and an expansion portion formed in one piece, wherein the flexible pipe is connected to the straight portion; and a flexible net is provided in the straight portion.

[0010] Preferably, the middle portion of the contraction portion is made of a flexible material, and a spring is provided between the middle portion of the contraction portion and the first bearing seat.

[0011] Preferably, the power assembly includes: a quick-release mechanism fixed to the mobile device through a bracket; a motor installed on the quick-release mechanism, and a driving wheel is coaxially fixed to the output end of the motor; a driven wheel fixed to the rotating drum or the rotating shaft, and the driving wheel and the driven wheel are connected by a belt drive.

[0012] Preferably, the quick-release mechanism includes: a mounting plate fixed to the bracket; a movable plate connected to the mounting plate via a hinge shaft, a side of the movable plate being provided with a clearance groove; a locking bolt passing through the clearance groove, the locking bolt being fixedly connected to the mounting plate and having fastening nuts arranged at both axial ends.

[0013] Preferably, the mobile device is provided with a visual sensor for monitoring the state of the grass and the state of the microneedles.

[0014] Compared with the prior art, the present invention provides an intelligent irrigation device for forage breeding, which has the following beneficial effects:

[0015] The mobile device in this invention is equipped with a visual sensor that monitors the plant's biological characteristics, such as leaf color, plant height, and canopy density, in real time. It also tracks the spatial position of the microneedles and the presence of surface deposits. When the sensor detects a lack of water in the grass, the system automatically adjusts the nozzle's spray angle for precise water replenishment. If deposits accumulate on the microneedles' surfaces, the system triggers the rotating drum to rotate to the corresponding position of the through-holes, activating the nozzle flushing mode and driving the spacing adjustment component to shorten the distance between the microneedles and the nozzle to enhance cleaning effectiveness. This closed-loop control, powered by real-time data, significantly improves operational accuracy and resource utilization.

[0016] The supply pipe in this invention utilizes a three-section flow channel structure, combined with a flexible mesh and springs, to create a comprehensive solution for "pressure buffering, medium mixing, and flow pattern optimization." The flexible material in the contraction section works in conjunction with the spring to absorb pressure fluctuations generated by the pipeline and maintain a stable flow rate. The flexible mesh within the straight section promotes thorough mixing of the water and fertilizer media through mechanical disturbances. The streamlined transition of the expansion section reduces turbulence intensity, extending the equipment's maintenance cycle.

[0017] Through the collaborative design of a removable bearing and a quick-release power assembly, this device allows for switching operating configurations within minutes. Operators simply loosen the locking pins and bolts to simultaneously replace the bearing on the slide. The quick-release mechanism then flips the movable plate to release the original transmission connection. This design allows a single device to accommodate multiple operating modes, allowing for adjustments based on specific circumstances. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned description of the drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, and this is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0027] Example: Please refer to Figure 1-Figure 7 In an embodiment of the present invention, an intelligent irrigation device for forage breeding is provided, comprising: a mobile device 1 and two symmetrically arranged spacing adjustment components installed on the mobile device 1; each of the spacing adjustment components has a spacing adjustment end, one of which is detachably mounted with a first supporting seat 5, and the other is detachably mounted with a second supporting seat 7; a rotating drum 8 is rotatably arranged in the first supporting seat 5, and a nozzle 81 is arranged on the rotating drum 8; a rotating shaft 9 is rotatably arranged in the second supporting seat 7, and a microneedle 91 is arranged on the rotating shaft 9; the rotating drum 8 and the rotating shaft 9 are respectively powered by a power assembly 10.

[0028] This device achieves overall displacement through a mobile device 1, which, in conjunction with symmetrically arranged spacing adjustment components, dynamically adjusts the spacing between two support bases (a first support base 5 and a second support base 7). Sprinklers 81 positioned on the surface of a rotating drum 8 within the first support base 5 evenly distribute irrigation liquid to the target area. The independently rotating shaft 9 within the second support base 7 drives microneedles 91 into the soil or vegetation layer, achieving precise localized operations (such as loosening soil, breaking up compacted soil, or assisting nutrient penetration).

[0029] It is worth mentioning that the detachable design facilitates the quick replacement of the bearing seat to adapt to various task scenarios, such as the "double-axis 9 mechanism" or the "double-drum 8 mechanism". The "double-axis 9 mechanism" means that the second bearing seat 7 can be detachably installed on each spacing adjustment end.

[0030] Specifically, the power assembly 10 includes: a quick-release mechanism fixed to the mobile device 1 through a bracket 12; a motor 108 installed on the quick-release mechanism, and a driving wheel 103 is coaxially fixed to the output end of the motor 108; a driven wheel 101 fixed to the rotating drum 8 or the rotating shaft 9, and the driving wheel 103 is connected to the driven wheel 101 through a belt 102.

[0031] Among them, the quick-release mechanism includes: a mounting plate 104 fixed to the bracket 12; a movable plate 105 connected to the mounting plate 104 through a hinge shaft, and a clearance groove 106 is opened on the side of the movable plate 105; a locking bolt 107 passing through the clearance groove 106, and the locking bolt 107 is fixedly connected to the mounting plate 104 and has fastening nuts at both axial ends.

[0032] The power assembly 10 utilizes a quick-release mechanism to rapidly adjust the position of the motor 108. When the first or second support 5 or 7 needs to be replaced, the nuts at each end of the locking bolt 107 are loosened, causing the movable plate 105 to tilt outward about its hinge axis, driving the motor 108 and driving pulley 103 downward, thereby releasing the transmission connection between the belt 102 and the driven pulley 101. Once the support is replaced, the movable plate 105 is reset, the locking bolt 107 is passed through the clearance slot 106 and re-tightened, and the driving pulley 103 establishes a transmission relationship with the new driven pulley 101 via the belt 102, resuming power transmission.

[0033] The quick-release mechanism provides sufficient operating space for the disassembly and assembly of the belt 102 through the downward movement design of the motor 108, avoiding the complication of operation caused by interference of transmission components when replacing the bearing seat, and significantly shortening the equipment debugging time.

[0034] More specifically, the distance adjustment component includes: a base 2 fixed to the mobile device 1, a slide 3 driven by a telescopic rod 4 is slidably provided on the base 2, the slide 3 serves as the distance adjustment end, and the slide 3 can cooperate with the first bearing seat 5 and be connected through the locking pin 6, or the slide 3 can cooperate with the second bearing seat 7 and be connected through the locking pin 6.

[0035] In this embodiment, a limiting cylinder 13 is also installed on the mobile device 1 through a support plate 11. The limiting cylinder 13 is sleeved on the outside of the rotating cylinder 8, and the support plate 11 is slidably set on the mobile device 1. It should be noted that the sliding direction of the support plate 11 is the same as the movable direction of the slide 3, and when the first supporting seat 5 is replaced with the second supporting seat 7, the support plate 11 moves to the edge position of the mobile device 1 to prevent interference with the rotating shaft 9 on the second supporting seat 7; the bottom of the limiting cylinder 13 has a dispersion nozzle 131 corresponding to the nozzle 81, and the side of the limiting cylinder 13 has a through hole 132 corresponding to the nozzle 81, and the through hole 132 is facing the direction of the microneedle 91.

[0036] When the nozzle 81 rotates to the position corresponding to the through hole 132, the spacing adjustment ends of the two spacing adjustment components are in a state of approaching each other; when the nozzle 81 rotates to the corresponding dispersion nozzle 131, the spacing adjustment ends of the two spacing adjustment components are in a state of moving away from each other.

[0037] This device achieves functional switching through the cooperation of a limiting cylinder 13 and a rotating drum 8. The limiting cylinder 13 is movably mounted on the mobile device 1. Its design, which fits over the exterior of the rotating drum 8, limits the rotational path of the nozzle 81. When the rotating drum 8 rotates the nozzle 81 until it aligns with the through-hole 132, the liquid sprayed from the nozzle 81 passes through the through-hole 132 and acts on the microneedles 91 in a targeted manner. This triggers the spacing adjustment assembly to move the slides 3 closer together, bringing the microneedles 91 into the effective cleaning range. When the nozzle 81 rotates to align with the dispersion nozzle 131, the liquid diffuses through the dispersion nozzle 131 to the area below. At this point, the spacing adjustment assembly drives the slides 3 farther apart, increasing the distance between the two support seats (the first support seat 5 and the second support seat 7). This prevents interference between the rotating drum 8 and the microneedles 91 during direct spraying. Interference between the rotating drum 8 and the microneedles 91 during direct spraying refers to the possibility that the microneedles 91 may drive soil into contact with the dispersion nozzle 131 or affect the direct spray coverage of the dispersion nozzle 131.

[0038] Of course, even if the liquid sprayed from the nozzle 81 acts on the microneedles 91 in a directionally manner through the through holes 132 , the liquid sprayed from the nozzle 81 can still achieve irrigation, but some uniformity will be lost.

[0039] Of course, after the microneedles 91 have finished working, the liquid sprayed from the nozzle 81 can be directed to act on the microneedles 91 through the through-holes 132. In short, by utilizing the alignment between the nozzle 81 and the through-holes 132, surface attachments can be automatically removed through directional flushing, maintaining the penetration performance of the microneedles 91 and extending the equipment maintenance cycle. The spacing adjustment component adjusts the position of the slide 3 in real time according to the operating mode, shortening the spacing during cleaning to improve cleaning efficiency, and widening the spacing during irrigation to ensure direct spray coverage and reduce interference. The limiting cylinder 13 integrates dual modes of directional spraying and diffuse spraying, which can be switched by rotating the rotating cylinder 8. No additional actuator is required, simplifying the structural complexity.

[0040] In this embodiment, the microneedle 91 is connected to the rotating shaft 9 via a thread, and the length of the microneedle 91 is configured such that when the mobile device 1 is placed on the ground, the microneedle 91 can extend to a predetermined ground depth.

[0041] Microneedles 91 are secured to the rotating shaft 9 via a threaded connection. When the power assembly 10 rotates the rotating shaft 9, the microneedles 91 rotate synchronously with it. Their length ensures that when the mobile device 1 is stationary, the microneedles 91 can penetrate the soil to the desired depth. This threaded connection allows for quick assembly and disassembly of the microneedles 91, facilitating the replacement of microneedles of varying specifications based on operational requirements (e.g., varying soil textures or target depths), enabling diverse soil conditions or operational objectives (e.g., loosening the topsoil or breaking up compacted layers).

[0042] In this embodiment, the central chamber of the first bearing seat 5 is rotatably connected to the supply pipe 53 through a sealed bearing 52. One end of the supply pipe 53 is connected to the rotating drum 8, and the other end is connected to the first tube body 14 through a rotatable joint; the first bearing seat 5 is also embedded with a second tube body 15, and the second tube body 15 is connected to the supply pipe 53 through a flexible tube 55.

[0043] Specifically, the first support 5 forms a rotationally sealed connection between the supply pipe 53 and the rotating drum 8 via a sealed bearing 52. One end of the supply pipe 53 connects to the first tube 14 (the primary supply source) via a rotatable joint, while the other end connects to the second tube 15 (the auxiliary supply source) embedded in the first support 5 via a flexible tube 55. When the system switches between supply modes, liquid or nutrient solution enters the supply pipe 53 through different pipelines and is delivered to the sprinkler 81 through the internal flow channel of the rotating drum 8. The sealed bearing 52 ensures a dynamic seal on the supply pipe 53 during the rotation of the rotating drum 8, while the flexible tube 55 compensates for any displacement caused by the rotation of the rotating drum 8, maintaining a stable connection between the second tube 15 and the supply pipe 53. By controlling the on / off states of the first and second tubes 14, 15, water and fertilizer can be supplied independently or mixed in proportion.

[0044] Furthermore, the supply pipe 53 is formed by an integrally formed contraction portion, a straight portion, and an expansion portion, wherein the flexible pipe 55 is connected to the straight portion; and a flexible net 51 is provided in the straight portion.

[0045] The middle portion of the contraction portion is made of a flexible material, and a spring 54 is provided between the middle portion of the contraction portion and the first supporting seat 5 .

[0046] In other words, the supply tube 53 adopts a three-section, integrated structure, with its contraction, straight section, and expansion section forming a gradual flow path design. When fluid enters the supply tube 53 through the first tube body 14, the flexible material in the middle of the contraction section undergoes controllable deformation under the action of fluid pressure. Combined with the elastic support of spring 54, the tube diameter is automatically adjusted to buffer pressure fluctuations and maintain a stable fluid flow rate. After the fluid enters the straight section, the flexible mesh 51 cuts and reorganizes the fluid through its mesh structure, disrupting the laminar flow state, promoting thorough mixing of the water and fertilizer media, and eliminating concentration gradients. This is particularly suitable for scenarios where water and fertilizer are supplied simultaneously, improving nutrient utilization.

[0047] In this embodiment, the mobile device 1 is provided with a visual sensor for monitoring the state of the grass and the state of the microneedles 91 .

[0048] The visual sensor on mobile device 1 uses an optical imaging system to collect real-time visual information of grass plants and microneedles 91. Grass monitoring includes parameters such as leaf color, plant height, and canopy density, with image comparison and analysis used to determine water requirements and health status. Monitoring of microneedles 91 focuses on their spatial position, surface coverage, and deformation. The sensor converts optical signals into electrical signals and transmits them to the control module, triggering the following actions: When the grass exhibits signs of water shortage, the spray angle and pressure of nozzle 81 are adjusted for precise water replenishment. When accumulation of surface deposits on microneedles 91 is detected, the rotating drum 8 is controlled to rotate to the position corresponding to through-hole 132, activating the nozzle 81 flushing mode and simultaneously driving the spacing adjustment component to shorten the spacing for enhanced cleaning.

[0049] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
