Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, specifically to a precision drip irrigation device for radish cultivation. Background Technology

[0002] Radish cultivation, as a water-intensive crop, has specific requirements for the spatial and temporal distribution of water and fertilizer supply during its tuber development stage. Traditional drip irrigation systems, which use a fixed ratio, are difficult to adapt to the dynamic nutrient demands from the seedling stage to the tuber enlargement stage, often resulting in nutrient excess in the early stages and insufficient supply in the later stages.

[0003] Existing equipment suffers from problems such as uneven particle size and insufficient mixing in the solid fertilizer processing stage, easily leading to drip irrigation line blockage and excessively high local concentrations. Conventional irrigation devices mostly use manual mechanical positioning for height adjustment, which cannot achieve precise height matching throughout the growth cycle, resulting in a mismatch between water penetration depth and root distribution. Furthermore, the fertilizer delivery system lacks a closed-loop control mechanism, and manual mixing errors can easily cause seedling burn. Simultaneously, existing technologies lack effective measures to address the arching characteristics of powdered materials, leading to supply interruptions and affecting irrigation continuity. These technical bottlenecks result in insufficient water and fertilizer utilization, severely restricting the improvement of radish quality and the benefits of large-scale cultivation. Summary of the Invention

[0017] 3. In this invention, the crusher and the screw feeder work together. After the high-speed crushing blades crush the lumpy fertilizer to the target particle size, the forced conveying mechanism of the screw blades overcomes the tendency of powder materials to clump together, ensuring that the material continuously and stably enters the mixing process. This streamlined process makes the physical form of the fertilizer suitable for the requirements of the drip irrigation system. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 - Appendix Figure 9This invention provides a precision drip irrigation device for radish cultivation, including a support frame 1. A feeding component 2 is disposed on the inner top of the support frame 1. The output end of the feeding component 2 is connected to a crushing component 3, and the output end of the crushing component 3 is connected to a mixing component 4. The output end of the mixing component 4 is connected to a conveying pipe 5. The mixing component 4 is connected to a drip irrigation component 6 via the conveying pipe 5. The drip irrigation component 6 includes an upper connecting plate 601, and an infusion pipe 602 is fixedly connected inside the upper connecting plate 601. The input end of the infusion pipe 602 is connected to one end of the conveying pipe 5. Multiple three-way valves 603 are connected inside the infusion pipe 602. A drip irrigation head 604 is threadedly connected to the output end of each three-way valve 603. Two sliding grooves 605 are formed on the side wall of the drip irrigation head 604. A sliding groove 605 penetrates the outer surface of the drip head 604 and is slidably connected to a baffle plate 606 inside. A telescopic rod 607 and a spring 608 are fixedly connected between the side wall of the baffle plate 606 and the inner wall of the sliding groove 605. The spring 608 is sleeved on the outside of the telescopic rod 607. A trigger rod 609 is fixedly connected to the lower end of the outer surface of the baffle plate 606. A lower connecting plate 610 is provided directly below the upper connecting plate 601. The upper connecting plate 601 and the lower connecting plate 610 are connected by a threaded rod 611. A trigger groove 612 is opened inside the lower connecting plate 610. The trigger groove 612 penetrates the outer surface of the lower connecting plate 610 and is located directly below the drip head 604. A support rod 613 is fixedly connected to the lower surface of the lower connecting plate 610.

[0022] Specifically, the support frame 1 serves as the main frame, bearing the load of the entire system. The top-mounted feeding assembly 2 within it is responsible for the quantitative distribution of various fertilizers, with automatic switching of raw materials achieved through a rotating loading structure. The crushing assembly 3 controls the particle size of the proportioned solid fertilizer, and the high-speed shearing action of the crusher 302 ensures the material meets subsequent processing requirements. The mixing assembly 4's stirring paddle 404, driven by the reducer 403, creates a turbulent field, improving the uniformity of water-fertilizer mixing. The conveying pipe 5 serves as a material transmission channel, maintaining the system's continuous operation capability. The drip irrigation assembly 6's upper connecting plate 601 and lower connecting plate 610 form an adjustable irrigation platform, and the infusion pipe 602 achieves multi-path diversion through a three-way valve 603. Control: The sliding groove 605 of the drip head 604 and the baffle plate 606 form a dynamic throttling mechanism. The elastic reset system composed of the telescopic rod 607 and the spring 608 automatically adjusts the flow cross section according to the contact pressure between the trigger rod 609 and the trigger groove 612. The lifting mechanism composed of the threaded rod 611 allows the drip height to be adjusted according to the crop growth stage. The support rod 613 ensures the structural stability of the irrigation unit. The components achieve fully automated control of the entire process from raw material ratio to precise drip irrigation through process-oriented cooperation. The flow distribution function of the three-way valve 603 and the pressure-sensitive adjustment characteristics of the baffle plate 606 form a dual flow control mechanism. The precision transmission of the threaded rod 611 ensures the spatial adaptability of the irrigation unit.

[0023] The batching assembly 2 includes a raw material tank 201, which is fixedly connected to the inner top of the support frame 1. A second motor 202 is fixedly connected to the center of the top of the raw material tank 201. A rotating shaft 203 is fixedly connected to the output end of the second motor 202. Multiple filling rings 204 are fixedly connected to the outer surface of the rotating shaft 203. A fertilizer tank 205 is slidably connected inside the filling rings 204. A discharge port 206 is opened on one side of the inner bottom end of the raw material tank 201. A third motor 207 is fixedly connected to the center of the inner bottom end of the raw material tank 201. A closing ring 208 is fixedly connected to the output end of the third motor 207. The closing ring 208 is rotatably connected inside the raw material tank 201. A conveying pipe 209 is connected to the bottom end of the raw material tank 201. A weighing assembly 210 is installed inside the conveying pipe 209.

[0024] Specifically, the batching component 2 achieves precise batching control through various functional units. The raw material tank 201, serving as a temporary storage container for multiple fertilizer varieties, is driven by a top motor 202 to rotate the shaft 203. The circular array layout of the filling ring 204 supports multiple fertilizer tanks 205, enabling parallel storage of raw materials. The sliding connection of the fertilizer tanks 205 facilitates quick changes in material types. The discharge port 206, as a raw material output channel, determines the material selection logic through position setting. The motor 207 drives the rotation of the closed ring 208 to control the opening and closing state of the discharge port 206. The conveying pipe 209 serves as a material transfer channel connecting the batching and crushing processes. The weighing component 210 changes the effective volume of the tube cavity through the displacement of the adjusting plate 2105, achieving precise control of the batching amount per operation. When all units work together, the angular displacement control of motor 202 determines the station switching of filling ring 204, and the opening and closing sequence of closed ring 208 and the volume adjustment of weighing component 210 form a closed-loop metering system to ensure that different types of fertilizers enter the subsequent processing stage in a set proportion.

[0025] The weighing assembly 210 includes a sliding groove 2101, which is formed inside the conveying pipe 209 and penetrates the side wall of the conveying pipe 209. A sealing cover 2102 is fixedly connected to the outer surface of the conveying pipe 209 and is fitted over the sliding groove 2101. A motor 2103 is fixedly connected inside the sealing cover 2102. A threaded rod 2104 is fixedly connected to the output end of the motor 2103 and is rotatably connected inside the sealing cover 2102. An adjusting plate 2105 is threadedly connected to the outer surface of the threaded rod 2104 and is slidably connected inside the conveying pipe 209.

[0026] Specifically, the weighing component 210 achieves volumetric metering through mechanical transmission. The sliding groove 2101 provides a guide trajectory for the adjusting plate 2105 and maintains the structural integrity of the conveying pipe 209. The sealing cover 2102 forms a sealed cavity to prevent material spillage while simultaneously supporting the drive unit. The motor 2103 outputs rotational torque to drive the threaded rod 2104 to generate precise angular displacement. The helical transmission characteristic of the threaded rod 2104 converts the rotational motion into linear displacement of the adjusting plate 2105. The sliding stroke of the adjusting plate 2105 within the conveying pipe 209 directly determines the effective volume of the cavity. During operation, the motor 2103 controls the number of rotations of the threaded rod 2104 according to the proportioning parameters, causing the adjusting plate 2105 to move to the target position and form a specific volumetric cavity. When the material fills the metering space formed by the adjusting plate 2105 and the pipe wall, a single quantitative dispensing is completed. This structure ensures metering repeatability through mechanical limiting, and the self-locking characteristic of the threaded rod 2104 maintains the positioning stability of the adjusting plate 2105. The crushing assembly 3 includes a crushing bucket 301, which is fixedly connected inside the support frame 1. The input end of the crushing bucket 301 is connected to the output end of the conveying pipe 209. A crusher 302 is fixedly connected inside the crushing bucket 301. The output end of the crushing bucket 301 is connected to a screw feeder 303, which is fixedly connected inside the support frame 1.

[0027] Specifically, the crushing component 3 achieves material transformation through grading. The crushing bucket 301, as a primary processing container, receives the proportioned raw materials and guides them into the crushing zone. The high-speed rotating blades of the crusher 302 generate shearing force to crush the lumpy fertilizer to the target particle size. The spiral blades of the screw feeder 303 forcefully convey the crushed material to the mixing section through axial propulsion. Its continuous operation ensures that there is no residue accumulation during the material transmission process. In the working process, the conical structure of the crushing bucket 301 guides the material to concentrate in the crushing zone, the blade group of the crusher 302 achieves the crushing effect, and the tubular shell of the screw feeder 303 and the gap between the blades form a directional conveying channel. The three work together to complete the physical transformation from lumpy material to powder. The forced feeding mechanism of the screw feeder 303 effectively overcomes the bridging phenomenon of powder materials.

[0028] The mixing component 4 includes a mixing tank 401, which is fixedly connected to the inner bottom of the support frame 1. The input end of the mixing tank 401 is connected to the output end of the screw feeder 303. A motor 402 and a reducer 403 are provided on the top of the mixing tank 401. The output end of the motor 402 is fixedly connected to the input end of the reducer 403. The reducer 403 is fixedly connected to the top of the mixing tank 401. An agitator 404 is rotatably connected inside the mixing tank 401. The output end of the reducer 403 is fixedly connected to the top of the agitator 404. A water inlet pipe 405 is connected to the second input end of the mixing tank 401. The output end of the mixing tank 401 is connected to the other end of the conveying pipe 5.

[0029] Specifically, the mixing component 4 achieves water and fertilizer homogenization through power transmission. The mixing tank 401, as a mixing container, receives the crushed solid materials and liquid water. The original speed output of the motor 402 is adjusted by the speed reducer 403 to obtain a suitable mixing torque. The transmission ratio conversion of the speed reducer 403 ensures that the mixing paddle 404 operates stably in the viscous medium. The rotational motion of the mixing paddle 404 generates radial and axial flow fields, allowing the solid and liquid phases to fully contact. The flow control function of the water inlet pipe 405 enables precise adjustment of the mixing concentration. During operation, solid materials are continuously input from the screw feeder 303, and water is injected proportionally through the water inlet pipe 405. The optimized speed output of the speed reducer 403 drives the mixing paddle 404 to form a three-dimensional mixing flow pattern. When the conveying pipe 5 discharges the mixed slurry, the continuous operation of the mixing paddle 404 prevents material deposition. The torque amplification characteristics of the speed reducer 403 ensure the mixing efficiency of high-viscosity materials, and the adjustable flow rate of the water inlet pipe 405 adapts to the moisture content requirements of different formulations.

[0030] Motor 6101 is fixedly connected to both ends of the lower connecting plate 610. Threaded rod 611 is fixedly connected to the output end of motor 6101. One end of threaded rod 611 is rotatably connected to the inside of the lower connecting plate 610, and the other end of threaded rod 611 is threadedly connected to the inside of the upper connecting plate 601.

[0031] Specifically, motor 6101 outputs rotational power to drive threaded rod 611 to generate angular displacement. The helical transmission characteristics of threaded rod 611 convert the rotational motion into the vertical displacement of upper connecting plate 601. Lower connecting plate 610, as the drive unit carrier, supports the rotational motion of threaded rod 611 through internal bearings. The threaded engagement between threaded rod 611 and upper connecting plate 601 forms a precision lifting mechanism. During operation, the bidirectional rotational control of motor 6101 causes upper connecting plate 601 to generate lifting motion. The lead parameter of threaded rod 611 determines the displacement corresponding to a unit rotation angle. This mechanism ensures the smoothness of the lifting process through synchronous drive of dual motors. The self-locking characteristics of the threaded pair maintain the height stability after adjustment, ultimately achieving precise matching between the drip irrigation head 604 and the crop roots.

[0032] A maintenance ladder 7 is fixedly connected to the outer surface of the support frame 1.

[0033] Specifically, the maintenance ladder 7 extends along the outer surface of the support frame 1 to form a vertical passage. Its stepped structure provides a safe climbing path. The fixed connection method of the maintenance ladder 7 ensures load-bearing stability. The step spacing and tread width are adapted to ergonomic requirements. The layout of the maintenance ladder 7 corresponds to the maintenance points of key equipment components. By establishing a three-dimensional maintenance passage, accessibility to all height levels of the equipment is achieved, providing a physical contact interface for daily inspections and troubleshooting. The support frame 1 has two observation platforms 8 fixedly connected inside and at the top. A moisture-proof board 801 is fixedly connected to one side of the upper surface of the top observation platform 8.

[0034] Specifically, observation platform 8 provides an operating platform for equipment operation monitoring. Its layered layout enables visual inspection of different workstations. The installation height of the top observation platform 8 is adapted to the field of vision of the main processing area. The moisture-proof board 801 forms a physical isolation layer to prevent the penetration of environmental moisture. The planar structure of observation platform 8 supports operators in equipment inspection and parameter adjustment. The inclined surface of the moisture-proof board 801 guides liquid flow to avoid water accumulation. The stepped layout of observation platform 8, combined with the protective function of the moisture-proof board 801, ensures that operators can safely conduct multi-angle observation of operating conditions during equipment operation. The drip head 604 is hollow inside and conical on the outside, with two sliding grooves 605 symmetrically distributed on the outer surface of the drip head 604.

[0035] Specifically, the drip head 604 optimizes liquid distribution through structural design. The internal hollow structure forms a flow channel to guide the directional flow of liquid fertilizer, while the external conical contour allows the liquid to form a uniform liquid film along the surface. Two symmetrically distributed sliding grooves 605 provide an installation interface for the dynamic adjustment mechanism. During operation, the liquid is transported to the cone apex area through the hollow cavity. The surface tension of the cone promotes uniform diffusion of the liquid, and the symmetrical layout of the sliding grooves 605 ensures the force balance of the flow adjustment mechanism. This combined structure enables the drip irrigation process to form a controllable laminar flow state. The tapering characteristic of the conical shape accelerates liquid convergence, and the symmetrical groove design maintains the synchronous movement accuracy of the adjustment mechanism.

[0036] A limiting post 10 is provided between the upper connecting plate 601 and the lower connecting plate 610. One end of the limiting post 10 is fixedly connected to the upper surface of the lower connecting plate 610, and the other end of the limiting post 10 passes through the upper connecting plate 601.

[0037] Specifically, the limiting post 10 ensures the motion accuracy of the lifting mechanism through mechanical constraints. Its fixed end is rigidly connected to the lower connecting plate 610 to form a reference positioning surface. The sliding fit section through the upper connecting plate 601 provides a vertical guide trajectory. During operation, the guiding effect of the limiting post 10 restricts the rotational freedom of the upper connecting plate 601, ensuring that only axial displacement occurs when the threaded rod 611 is driven. The clearance fit between the post and the upper connecting plate 601 allows for smooth sliding while preventing off-center loading. This structure maintains the coaxiality of the lifting process through a double limiting mechanism. The length of the through section is designed to cover the entire stroke range. The rigidity of the limiting post 10 effectively absorbs lateral loads, ensuring the structural stability of the drip irrigation component 6 during dynamic adjustment.

[0038] Working Principle: In use, first, fix the support rod 613 within the working area and adjust the distance between the radish and the drip irrigation head 604. Then, different types of solid fertilizer piled on the moisture-proof plate 801 are put into different fertilizer tanks 205. The mixing ratio parameters are then set to mix the solid fertilizer. According to the mixing ratio parameters, start motor 202 to drive the filling ring 204 on the rotating shaft 203 to rotate, making the output end of the fertilizer tank 205 containing the specific type of fertilizer coincide with the discharge port 206 of the raw material tank 201. Then, start motor 207 to drive the closing ring 208 to rotate away from the discharge port 206. At this time, the fertilizer in the fertilizer tank 205 falls into the conveying pipe 209 under the influence of gravity. The maximum lift of the conveying pipe 209 is a fixed value. The number of times fertilizer enters the conveying pipe 209 is determined according to the mixing ratio parameters (the density of conventional fertilizer is a known value). If the required lift of the fertilizer participating in the mixing is less than the maximum lift of the conveying pipe 209... At this point, motor 42103 can be started to drive threaded rod 2104 to move adjusting plate 2105 longitudinally along conveying pipe 209, thereby changing the real-time lift value of conveying pipe 209 to adapt to different proportion requirements; after the proportion is completed, the fertilizer with the appropriate proportion enters crushing hopper 301, and is then crushed by the high-speed blades of internal crusher 302; different types of fertilizer can be continuously fed in during crushing, and the crushed fertilizer is forcibly conveyed to mixing tank 401 by screw conveyor 303 through screw blades; in mixing tank 401, motor 5402 drives stirring paddle 404 through speed reduction gear 403 to perform stirring motion, thereby improving the mixing degree of various fertilizers; during the stirring process, an appropriate amount of water is added through water inlet pipe 405 to achieve water and fertilizer integration, ultimately The mixed fertilizer flows out from the output end of the mixing tank 401 and enters the drip head 604 along the infusion pipe 602 under the action of the delivery pipe 5. Then, the motor 6101 is started to drive the threaded rod 611 to rotate, thereby changing the distance between the upper connecting plate 601 and the lower connecting plate 610. When the upper connecting plate 601 moves closer to the lower connecting plate 610, the trigger rod 609 on the outside of the drip head 604 hits the trigger groove 612. Under the action of the reaction force, the trigger rod 609 drives the blocking plate 606 to compress the telescopic rod 607 and the spring 608, thereby causing the fertilizer inside the drip head 604 to flow out. Since the drip head 604 is conical and the volume of the sliding groove 605 is small, the liquid fertilizer gathers along the outer surface of the drip head 604 to the tip of the cone, ultimately forming the drip irrigation effect.

[0039] During equipment operation, operators can access the double-layer observation platform 8 via maintenance ladder 7 to monitor the operating conditions.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
