Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural irrigation technology, in particular to an agricultural water-saving alternate irrigation device. BACKGROUND

[0002] Water, as the lifeblood of agricultural production, is the core element to ensure food security. About 70% of the global freshwater withdrawal is used for agricultural irrigation, and this proportion is more than 90% in many developing countries. However, with the intensification of climate change and the continuous growth of population, water shortage has become a prominent bottleneck for global agricultural development. Many regions such as North China and northern India are facing serious water resource pressure, and drought is the primary natural disaster that leads to crop reduction or even complete loss.

[0003] At the same time, the problem of low water use efficiency in agriculture is particularly serious. Traditional flood irrigation is still widely used, and the effective use rate of water is less than 50%. A large amount of water resources is wasted due to leakage and evaporation in the delivery and field links, which not only exacerbates water scarcity, but also causes a series of ecological and geological problems such as overexploitation of groundwater and water eutrophication. To solve this dilemma, water-saving irrigation technology has become the core direction of industry development. As of the end of 2023, the area of efficient water-saving irrigation in China has reached 410 million mu, and the effective use coefficient of irrigation water in farmland has increased to 0.576, but there is still room for improvement compared to the demand for agricultural water saving. The current mainstream technologies of sprinkling irrigation and drip irrigation can achieve water-saving effects of 20%-30% and 30%-50%, respectively, but they still have obvious limitations.

[0004] Most drip irrigation systems lack flexible water flow control mechanisms and are difficult to achieve precise differentiated water supply for crops in different regions. Although some alternate irrigation modes such as dry-wet alternate irrigation (AWD) have been promoted, they still have the risk of crop yield reduction and rely on complex control parameters, which limits their practicality. In addition, the water flow distribution of traditional irrigation devices is controlled as a whole, which cannot independently adjust different irrigation pipelines, resulting in poor irrigation uniformity, coexistence of local waterlogging and drought, and further reducing water resource utilization efficiency. More importantly, irrigation water sources often contain impurities such as sand and weeds, which can easily cause blockage of irrigation pipelines and water outlet components. The existing filter devices are mostly fixed structures, which are inconvenient to disassemble and clean, and can easily cause irrigation efficiency to decline or even affect the service life of the device after long-term use.

[0005] Therefore, an agricultural water-saving alternate irrigation device is proposed to solve the above problems. SUMMARY

[0039] Further, the mounting groove 64 is symmetrically distributed inside the mounting ring 61, the mounting block 65 is slidably connected inside the mounting groove 64, the mounting block 65 is symmetrically distributed outside the filter disc 66, and the filter disc 66 is located between the mounting ring 61 and the threaded pipe 63.

[0040] Specifically, the mounting base 1 serves as the basis of the entire device, which is made of high-strength corrosion-resistant metal or engineering plastic, which not only provides stable support for the transfer box 2 on the top, but also adapts to the complex soil environment and climate conditions of farmland, avoiding tilting of the device due to rust or aging after long-term use, ensuring the stability of the overall structure. The transfer box 2, as the core water transfer component, its internal space design needs to be combined with the number and flow demand of the irrigation pipe 3, generally adopting cylindrical or cuboid structure, the inner wall is treated with smoothness to reduce water resistance, and the thickness of the wall is optimized according to the actual water pressure to prevent rupture due to high water pressure. The fixed irrigation pipes 3 on the outside are designed symmetrically, which not only ensures uniform coverage of the irrigation areas on both sides, but also avoids local waterlogging or drought in farmland by alternating water supply, further improving water saving effect. The drip pipes 31 evenly distributed at the bottom of the irrigation pipe 3 have hole diameters customized according to the water demand of different crops, such as smaller hole diameters for drought-resistant crops to reduce water output per unit time, and larger hole diameters for water-loving crops. At the same time, anti-clogging lines are usually arranged on the outside of the drip pipes 31 to reduce the probability of silt blockage.

[0041] As a further embodiment of the present scheme, the transfer box 2 is fixedly connected with a water inlet pipe 4 on the outside, and a drain pipe 21 is fixedly connected to the outside of the bottom of the transfer box 2. The irrigation pipes 3 are symmetrically distributed on the outside of the transfer box 2, and the drip pipes 31 are evenly distributed at the bottom of the irrigation pipes 3. The water inlet end of the drain pipe 21 is located in the inner bottom wall of the transfer box 2, and the water outlet end of the water inlet pipe 4 is located inside the transfer box 2.

[0042] It should be noted that: flow regulating mechanism 5, the movable tube 51 is symmetrically distributed on the top of the transfer box 2, the height design needs to facilitate the operator to rotate the rotating handle 52, generally controlled in the range of comfortable standing operation of adult, and the connecting part of the movable tube 51 and the transfer box 2 will be provided with sealing washer to prevent water leakage from the connecting part; The surface of the rotating handle 52 will increase the anti-skid pattern to improve the friction when operating, avoid hand slipping, and the thread accuracy of the screw rod 53 and the sleeve ring 54 needs to be strictly controlled to ensure that the sleeve ring 54 can move up and down smoothly when the screw rod 53 rotates, and then drive the shielding plate 56 to accurately adjust the shielding degree of the water outlet 57, and the adaptive design of the sliding groove 58 and the shielding plate 56 not only limits the moving direction of the shielding plate 56 to prevent it from deviating and affecting the shielding effect, but also applies wear-resistant lubricating grease to the inner wall of the sliding groove 58 to reduce the wear of the shielding plate 56 when sliding, prolong the service life of the component, and the shielding plate 56 is made of corrosion-resistant and high-strength plastic or metal material to ensure that it is not easy to deform under long-term water immersion and effectively shield the water outlet 57.

[0043] Further, in the filter dismounting mechanism 6, the mounting ring 61 is symmetrically distributed on the outside of the transfer box 2, the inner diameter is strictly matched with the outer diameter of the threaded through pipe 63, the sealing property of the threaded connection is ensured, and water leakage is avoided, at the same time, the wall thickness of the mounting ring 61 will be designed according to the connection strength requirement to prevent the threaded connection from breaking, the thread density on the surface of the threaded through pipe 63 needs to be moderate to ensure the firmness of the connection with the internal thread groove 62 of the mounting ring 61 and facilitate the operator to quickly screw and dismount, and the connecting part of the threaded through pipe 63 and the irrigation pipe 3 adopts integrated forming or welding process to enhance the connection strength and prevent the threaded through pipe 63 from falling off due to water impact; The filter hole diameter of the filter disc 66 will be selected according to the impurity condition of the water source, generally between 50-100 microns, which can effectively filter the sand, weeds and other impurities in the water to avoid clogging the dropper 31, and will not excessively hinder the water flow to affect the irrigation efficiency, and the mounting block 65 symmetrically distributed on the outside of the filter disc 66 and the mounting groove 64 in the mounting ring 61 adopt clearance fit, the clearance is controlled between 0.1-0.3mm, which can facilitate the mounting block 65 to quickly slide into the mounting groove 64 to complete the installation of the filter disc 66, and can ensure the stability of the filter disc 66 after installation to prevent the filter disc 66 from deviating due to water impact, at the same time, a small protrusion will be arranged on the top of the mounting block 65, when the filter disc 66 is installed in place, the protrusion can be clamped into the clamping groove in the inner wall of the mounting groove 64 to further fix the filter disc 66 and prevent it from loosening under the action of water.

[0044] Work flow: the agricultural water-saving alternate irrigation device is based on the installation base 1, the top fixed transfer box 2 is the core water transfer component, when working, the external water source first enters the transfer box 2 through the fixed water inlet pipe 4 outside the transfer box 2.

[0045] When alternating irrigation adjustment is needed, the flow rate adjustment mechanism 5 can be used, and the specific operation is to rotate the rotating handle 52 inside the movable pipe 51 to drive the fixed screw rod 53 to rotate. Since the sleeve ring 54 on the outside of the screw rod 53 is threadedly connected with the screw rod 53, the rotation of the screw rod 53 will make the sleeve ring 54 move up and down along the screw rod 53, and then the sleeve ring 54 outside the fixed connecting rod 55 drives the shielding plate 56 to slide in the sliding groove 58 on the inner wall of the transfer box 2, and the shielding plate 56 is movably connected outside the water outlet 57 and has an area larger than the water outlet 57. By adjusting the shielding degree of the shielding plate 56 to the water outlet 57, the water flow rate from the transfer box 2 to the irrigation pipe 3 can be controlled. At the same time, by adjusting the positions of the shielding plates 56 on different sides, the alternating water supply of the irrigation pipes 3 on both sides can be realized.

[0046] After the water flow flows out of the water outlet 57, it will first pass through the filter dismounting mechanism 6. The mounting ring 61 is fixed outside the transfer box 2, the threaded pipe 63 at one end of the irrigation pipe 3 is connected with the transfer box 2 through the threaded connection with the threaded groove 62 inside the mounting ring 61, and the filter disc 66 is slidably connected with the mounting groove 64 inside the mounting ring 61 through the symmetrically arranged mounting blocks 65 on the outside, and is located between the mounting ring 61 and the threaded pipe 63. When the water flow passes through the filter disc 66, impurities are filtered out. The filtered water flow enters the irrigation pipe 3, and then slowly drips into the farmland through the drip pipes 31 evenly distributed at the bottom of the irrigation pipe 3, achieving the effect of water-saving irrigation.

[0047] When the filter disc 66 needs to be cleaned, the threaded pipe 63 is simply unscrewed, and the mounting block 65 is slid out of the mounting groove 64, so that the filter disc 66 can be removed for cleaning or replacement, ensuring the continuous and stable operation of the device.

[0048] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
