Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation equipment technology, and in particular to an irrigation device for cultivation in saline-alkali land. Background Technology

[0002] In the agricultural development and utilization of saline-alkali land, a scientific and reasonable irrigation system is crucial for improving soil structure, reducing soil salinity, and ensuring normal crop growth. Currently, drip irrigation or micro-sprinkler irrigation technology is commonly used for the cultivation of cash crops such as tomatoes in saline-alkali land in order to accurately control water volume and improve water resource utilization. However, because the water sources in saline-alkali areas usually have high mineralization and contain more salt and calcium and magnesium ions, coupled with the complex field operation environment, irrigation water is easily affected by temperature during pipeline transportation and spraying, resulting in crystallization or the mixing of small impurities such as mud and sand.

[0003] These crystals and impurities easily accumulate at the nozzles or drippers at the end of the pipeline network, causing frequent physical blockages in the irrigation nozzles. Once a blockage occurs, it will not only cause uneven irrigation and affect crop growth, but in severe cases it may even cause excessive pressure in the local pipeline network and damage the equipment. Therefore, regularly disassembling, cleaning and maintaining the large number of nozzles distributed in the field has become a high-frequency and necessary daily task in the planting management of saline-alkali land.

[0004] In existing irrigation systems, sprinkler heads and branch pipes are mostly fixed using traditional threaded connections or adhesive bonding. Adhesive bonding obviously cannot meet the needs of disassembly and cleaning. While threaded connections are detachable, they have significant drawbacks in actual operation: First, the process of tightening and loosening threads is cumbersome, requiring multiple rotations to complete the disassembly and assembly of a single sprinkler head, and often requires the use of auxiliary tools such as wrenches. For cleaning hundreds or thousands of sprinkler heads, this is extremely time-consuming, labor-intensive, and inefficient. Second, saline-alkali environments are corrosive to metal or plastic threads, and frequent tightening can easily lead to thread wear and stripping, which in turn can cause water leakage or connection failure at the joint.

[0005] Therefore, this utility model proposes an irrigation device for cultivation in saline-alkali land to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an irrigation device for saline-alkali land cultivation, which aims to improve the problem of frequent clogging of nozzles in some existing saline-alkali land cultivation irrigation devices due to water crystallization.

[0007] This utility model provides an irrigation device for saline-alkali land cultivation, including: a water storage tank, a support pipe, a booster pump, a main pipe and a secondary pipe. The water storage tank is connected to the main pipe through a pipeline. The booster pump is installed on the side wall of the support pipe to pressurize the water flow. A disassembly mechanism is set at the bottom of the secondary pipe. The disassembly mechanism mainly includes a fixing pipe, a driving component, a retaining ball, a spring and an alignment pipe.

[0008] The fixed tube is fixedly connected to the bottom end of the secondary pipe. The alignment tube is inserted inside the fixed tube. The bottom end of the alignment tube is connected to a nozzle. A through hole is opened on the side wall of the fixed tube. The locking ball is movably embedded in the through hole. The driving assembly is slidably sleeved on the outside of the fixed tube. The spring abuts between the inner wall of the driving assembly and the outer wall of the fixed tube.

[0009] Furthermore, under the action of the spring force, the inner wall of the drive assembly abuts against the outer side of the locking ball, restricting the outward movement of the locking ball and causing the locking ball to protrude from the inner wall of the fixed tube and then lock into the outer wall of the alignment tube. The physical locking and rapid release of the alignment tube and the nozzle are achieved by the cooperation of the drive assembly and the spring.

[0010] Preferably, the drive assembly includes a pull ring and a connecting ring fixedly connected to the inner ring of the pull ring. The inner peripheral wall of the connecting ring is slidably engaged with the outer peripheral wall of the fixed tube, and the inner side of the connecting ring forms a limiting surface for abutting the ball. The pull ring drives the connecting ring to move to change the constraint state on the ball.

[0011] Preferably, the spring is sleeved on the outside of the fixed tube, with one end of the spring abutting against the end face of the connecting ring and the other side of the spring abutting against the flange of the outer wall of the fixed tube. Pulling the pull ring upward can drive the connecting ring to move upward and squeeze the spring, so that the connecting ring releases the radial restriction on the ball, and the ball can extend outward and disengage from the alignment tube, thereby realizing the quick disassembly of the nozzle.

[0012] Preferably, an annular groove is formed on the outer peripheral wall of the alignment tube near the top. When the alignment tube is inserted into the fixing tube, the locking ball is engaged in the annular groove to lock the alignment tube and the nozzle, ensuring that the nozzle will not accidentally fall off under water pressure.

[0013] Preferably, a mixing mechanism is installed at the top of the water storage tank. The mixing mechanism includes a double-ring shell fixedly installed at the top of the water storage tank and a motor disposed on one side of the double-ring shell and serving as a drive source. The top of the double-ring shell is connected to a vertically upward feeding pipe, and the bottom of the double-ring shell is connected to the inside of the water storage tank for pre-mixing the liquid before irrigation.

[0014] Preferably, the double-ring shell has a double-ring interlocking structure, and two sets of non-interfering central rods are rotatably inserted inside the double-ring shell. The motor output shaft is connected to the central rods for transmission, and the internal fluid moves through the rotation of the central rods.

[0015] Preferably, each set of central rods has two blades fixedly connected to the outer side inside the double-ring shell. When the central rod rotates, it drives the blades to stir and mix the liquid medicine, and the shearing action of the blades improves the mixing uniformity.

[0016] Preferably, the main pipeline is horizontally arranged, and several secondary pipelines are vertically connected to both sides of the main pipeline and arranged in an array. The support pipe is vertically arranged next to the water storage tank, and the two ends of the booster pump are connected in series to the water supply pipeline through flanges, forming a stable pipeline support structure with a wide coverage area.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of frequent clogging of nozzles due to water crystallization in existing saline-alkali land irrigation technology, and the cumbersome disassembly of traditional threaded connections requiring tools and having low maintenance efficiency. It achieves the technical effect of quick and easy insertion and removal of nozzles with one hand without auxiliary tools, greatly improving the cleaning and maintenance efficiency of irrigation system, and the connection is stable and can effectively resist the impact of high-pressure water flow.

[0018] 2. This utility model solves the problems of uneven mixing, excessively high local concentration that can burn crops, or sedimentation caused by directly adding the pesticide solution to the water storage tank in existing irrigation systems by integrating a mixing mechanism on the top of the water storage tank. It utilizes a double-ring shell in a double-ring shape in conjunction with a central rod and blades driven by a motor. This achieves the technical effect of fully pre-mixing and stirring the pesticide solution and water source before irrigation, enhancing the fluid disturbance effect by utilizing the double-ring structure, ensuring uniform and stable quality of the output irrigation water, and guaranteeing the safe growth of crops.

[0019] 3. This utility model solves the problem that conventional quick couplings are prone to accidental detachment due to elasticity decay or water pressure fluctuations after long-term use by adopting a mechanical locking method in which the inner wall of the connecting ring abuts against the ball, and by using a spring to provide continuous reset pre-tightening force. It achieves the technical effect of ensuring the sealing and reliability of the nozzle and pipeline connection while ensuring convenient disassembly, and preventing water leakage or detachment accidents by using the mechanical self-locking principle.

[0022] Example: Reference Figures 1 to 4 This utility model provides an irrigation device for saline-alkali land cultivation, which aims to solve the structural defects in existing saline-alkali land irrigation technology, such as frequent nozzle blockage caused by water crystallization, and the difficulty, inefficiency, and inability to achieve quick one-handed insertion and removal of nozzles due to the traditional threaded connection method.

[0023] like Figure 1 and Figure 2 As shown, an irrigation device for saline-alkali land cultivation includes a water storage tank 1 and an irrigation pipeline assembly installed on one side of the water storage tank 1. The water storage tank 1 is used to store the prepared irrigation water or chemical solution, providing a liquid source for the entire irrigation system. A support pipe 2 is vertically installed on one side of the water storage tank 1. The support pipe 2 serves as the main support structure, and a booster pump 3 is fixedly installed on its side wall. The booster pump 3 is connected in series with the water pipeline through a flange to pressurize the flowing water to overcome the friction resistance along the long distance and ensure the end-sprinkler pressure. The water pipeline is supported and laid out based on the support pipe 2. The upper end of the support pipe 2 extends and connects to a horizontally installed main pipe 4. Several secondary pipes 5 are vertically connected to both sides of the main pipe 4 in an array. The main pipe 4 is used to collect and guide the pressurized water source, and the secondary pipes 5 are used to further distribute the water source to specific planting ridges or crop root areas. The array of secondary pipes 5 can cover a large area of ​​saline-alkali land cultivation.

[0024] like Figure 2 and Figure 4As shown, a disassembly mechanism 7 is provided at the bottom of the secondary pipe 5. The disassembly mechanism 7 mainly consists of a fixed pipe 73, a drive assembly 72, a retaining ball 74, a spring 75, and an alignment pipe 76. The fixed pipe 73 is fixedly connected to the bottom of the secondary pipe 5 and communicates with the inside of the secondary pipe 5. The fixed pipe 73 serves as the stationary base of the disassembly mechanism 7, and the alignment pipe 76 is inserted inside it. The bottom end of the alignment pipe 76 is connected to a nozzle 71, which is used to atomize or drip water to the roots of the tomato crop. The alignment pipe 76 can be inserted and removed axially inside the fixed pipe 73. The drive assembly 72 is slidably sleeved on the outer periphery of the fixed pipe 73. The drive assembly 72 can slide back and forth along the axial direction of the fixed pipe 73. A spring 75 is provided between the wall and the outer peripheral wall of the fixed tube 73. The spring 75 is in a compressed state or a pre-tightened state, which is used to apply a reset force to the drive assembly 72, so that the drive assembly 72 always maintains a downward movement trend. Several through holes are evenly opened in the circumferential direction on the side wall of the fixed tube 73. The inner diameter of the through hole is adapted to the diameter of the locking ball 74. The locking ball 74 is movably embedded in the through hole. The locking ball 74 can move radially in the through hole, but in the unlocked state, it is restricted by the obstruction of the drive assembly 72 and protrudes inward. The fixed tube 73, the drive assembly 72 and the locking ball 74 in the disassembly mechanism 7 form a specific structural cooperation and connection relationship, realizing the function of quick connection and separation using the mechanical ball lock principle.

[0025] Please refer to the following carefully. Figure 4 The core structure of the disassembly mechanism 7 will be described in detail below: The drive assembly 72 includes a pull ring 721 and a connecting ring 722 fixedly connected to the inner ring of the pull ring 721. The pull ring 721 is located outside the fixed tube 73 and is used for the operator to grip and apply pulling force. The connecting ring 722 is located inside the pull ring 721, and the inner peripheral wall of the connecting ring 722 is clearance-fitted with the outer peripheral wall of the fixed tube 73, so that the connecting ring 722 can slide smoothly along the axial direction of the fixed tube 73. The inner side wall of the connecting ring 722 forms a limiting surface for abutting the locking ball 74. The spring 75 is sleeved on the outside of the fixed tube 73. The top end of the spring 75 abuts against the step surface corresponding to the bottom or top surface of the connecting ring 722, and the other end of the spring 75 abuts against the flange of the outer wall of the fixed tube 73. In the natural state, the spring 75 provides elastic force to keep the connecting ring 722 in the first position. At this time, the inner wall of the connecting ring 722 tightly abuts against the outer side of the locking ball 74, forcing the locking ball 74 to be unable to move outward.

[0026] An annular groove is formed on the outer peripheral wall of the alignment tube 76 near its top end. The cross-sectional shape of the annular groove is adapted to the spherical surface of the locking ball 74. When the alignment tube 76 is fully inserted into the fixed tube 73, the locking ball 74, under the squeezing action of the inner wall of the drive assembly 72, partially passes through the through hole of the fixed tube 73 and protrudes to the inner side of the fixed tube 73, thus locking into the annular groove of the alignment tube 76. This spherical locking structure axially locks the alignment tube 76 into the fixed tube 73, preventing water pressure from dislodging the nozzle 71 and the alignment tube 76, and also restricts the rotation of the alignment tube 76, ensuring a stable connection. When disassembling nozzle 71, pull ring 721 upward. Pull ring 721 drives connecting ring 722 to move upward against the resistance of spring 75. When connecting ring 722 moves to the predetermined height, the inner wall of connecting ring 722 no longer applies radial constraint to ball 74, or the inner side of connecting ring 722 is provided with a clearance groove aligned with ball 74. At this time, ball 74 is released from radial restriction. Pull nozzle 71 downward to drive alignment tube 76 downward. The side wall of the groove of alignment tube 76 squeezes ball 74 to retract it outward into the through hole of fixed tube 73, thereby realizing the separation of alignment tube 76 and fixed tube 73.

[0027] For the installation of power sources such as booster pump 3 and motor 61 mentioned later, those skilled in the art can use commercially available conventional models and install and control them by conventional methods such as bolt fixing and wire connection to the controller. The specific electrical control principle and internal structure are well-known technologies in the field and will not be described in detail here.

[0028] like Figure 1 and Figure 3 As shown, a mixing mechanism 6 is fixedly installed at the top of the water storage tank 1. The mixing mechanism 6 is integrated into the top of the water storage tank 1 as an independent mixing unit. It can use gravitational potential energy to directly introduce the mixed liquid into the water storage tank 1. The mixing mechanism 6 mainly includes a double ring shell 62, a motor 61, a central rod 63, and blades 64. The double ring shell 62 is fixedly connected to the opening on the top surface of the water storage tank 1. The double ring shell 62 is in the shape of two overlapping and fused circular shell parts. This double ring structure can provide a more complex fluid disturbance path in a limited space and enhance the mixing effect. The top of the double ring shell 62 is connected to a vertically upward feed pipe 65. The feed pipe 65 is used to put the concentrated medicine or powder to be mixed into the double ring shell 62. The bottom of the double ring shell 62 is directly connected to the internal cavity of the water storage tank 1, so that the mixed liquid can flow down.

[0029] A motor 61 is fixedly installed on one side of the outer wall of the double ring shell 62. The motor 61 serves as a power source, and its output shaft passes horizontally through the side wall of the double ring shell 62 and extends into the interior. A central rod 63 is horizontally inserted inside the double ring shell 62. The central rod 63 passes through the interior of the double ring shell 62 and is connected to the output shaft of the motor 61 through a coupling or direct drive. Under the drive of the motor 61, the central rod 63 can rotate at high speed inside the double ring shell 62.

[0030] like Figure 3 As shown, the central rod 63 is fixedly connected to two or more blades 64 on the outer peripheral wall inside each annular space of the double-ring shell 62. The blades 64 are evenly distributed around the central rod 63, and the shape of the blades 64 can be designed as spiral or paddle. When the central rod 63 drives the blades 64 to rotate at high speed, the blades 64 generate strong shearing and disturbance effects on the liquid medicine and water flowing into the double-ring shell 62, forcing the liquid to generate turbulence in the double-ring cavity, thereby realizing the rapid and thorough mixing of the liquid medicine and water, and then flowing into the water storage tank 1 below for storage.

[0031] like Figure 1 As shown, the support pipe 2 is vertically erected next to the water storage tank 1 and fixed to the side wall of the water storage tank 1 through connectors to enhance the overall wind and toppling resistance. The main pipe 4 is horizontally erected at a certain height, and several secondary pipes 5 are vertically connected to both sides of the main pipe 4 and arranged in an array with equal spacing to form a pipe network structure covering the rectangular planting area. This array arrangement facilitates the unified management and maintenance of the nozzles 71 in the future, and also ensures that the water pressure in each secondary pipe 5 is relatively balanced.

[0032] The working principle of this utility model is as follows: When irrigation of saline-alkali land is required, the first step is to prepare the solution. The worker pours the required concentrated solution or powder into the feed pipe 65, and at the same time starts the motor 61 in the mixing mechanism 6. The motor 61 drives the central rod 63 to rotate at high speed inside the double ring shell 62, which in turn drives the blades 64 fixed on the central rod 63 to rotate synchronously. The blades 64 strongly stir and shear the water and solution flowing through the double ring shell 62. The evenly mixed solution flows into the storage tank 1 for storage and later use. This premixing method effectively avoids the problem of excessively high local concentration or sedimentation caused by directly adding the solution to the large tank.

[0033] Then, the booster pump 3 is turned on, and the mixed water in the water storage tank 1 is drawn and transported to the booster pump 3 through the pipeline. After being pressurized by the booster pump 3, the water flows upward along the support pipe 2 and finally merges into the main pipe 4. The water flow is divided in the main pipe 4 and enters each of the secondary pipes 5. It then flows along the secondary pipes 5 to the nozzles 71 at each end, through which the tomato crop is precisely drip-irrigated or sprinkled.

[0034] When nozzle 71 needs cleaning and maintenance due to blockage caused by salt crystallization or impurities in the water, or when nozzle 71 needs to be replaced with a different specification, the operator can disassemble it with just one hand without using auxiliary tools such as wrenches. The specific operation is as follows: the operator pulls the pull ring 721 on the drive assembly 72 upwards. The pull ring 721 drives the inner fixed connecting ring 722 to slide upwards along the outer wall of the fixed tube 73. During this process, the connecting ring 722 compresses the spring 75. When the connecting ring 722 moves upwards to a certain position, the inner wall of the connecting ring 722 releases the radial contact restriction on the ball 74, and the ball 74 is in a free state.

[0035] Subsequently, the operator pulls the nozzle 71 downwards, which causes the alignment tube 76 to move downwards. The annular groove sidewall of the outer wall of the alignment tube 76 squeezes the retaining ball 74, forcing the retaining ball 74 to move radially outwards and retract into the through hole of the fixing tube 73. This releases the axial locking of the retaining ball 74 to the alignment tube 76, allowing the alignment tube 76 and the nozzle 71 to be easily pulled out of the fixing tube 73, completing the disassembly.

[0036] The installation process is the opposite: insert the alignment tube 76 into the fixing tube 73, release the pull ring 721, and under the action of the spring 75's return force, the connecting ring 722 moves down and squeezes the locking ball 74 to move inward and lock into the annular groove of the alignment tube 76, achieving rapid and automatic locking. The whole process is simple and quick, greatly improving the maintenance efficiency of the saline-alkali land irrigation system.
