Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment technology, specifically to an irrigation device for millet cultivation. Background Technology

[0002] Traditional millet irrigation methods mostly rely on flood irrigation or furrow irrigation, which not only consume a large amount of water resources but also easily lead to problems such as soil compaction and nutrient loss due to uneven water distribution, making it difficult to meet the needs of precision farming in modern agriculture. With the increasing scarcity of water resources and the deepening of the concept of sustainable agricultural development, water-saving drip irrigation technology has become an important direction for improving the efficiency of millet cultivation.

[0003] Existing millet irrigation devices have significant shortcomings in preventing drip head clogging. Because the water in millet-growing areas often contains a high amount of impurities such as silt and minerals, and soil particles may be introduced during irrigation, these impurities easily accumulate in the tiny outlet holes of the drip head, causing blockages. Most drip heads lack effective self-cleaning functions; once clogged, they must be manually disassembled and cleaned one by one, which is not only time-consuming and labor-intensive but also causes irrigation interruptions due to maintenance downtime, affecting millet growth. Furthermore, some drip heads, in pursuit of water-saving effects, have excessively small outlet holes, further exacerbating the risk of clogging and leading to a significant decrease in irrigation uniformity. In severe cases, this can even cause localized areas of millet to stunt growth due to water shortage. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an irrigation device for millet cultivation, which has advantages such as preventing drip head clogging and solves the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an irrigation device for millet cultivation, comprising a drip irrigation tape, one end of which is connected to a first inclined sleeve via a clamp, one end of which is connected to a second inclined sleeve via bolts, a retaining ring fixedly connected to the inner wall of the second inclined sleeve, a filter screen fixedly connected to the end face of the retaining ring via screws, a drain pipe fixedly connected to the outer wall of the second inclined sleeve, a screw cap threadedly connected to the bottom end of the drain pipe, and multiple drip irrigation components fixedly connected at equal intervals on the outer surface of the drip irrigation tape;

[0008] The drip irrigation assembly includes a pipe connector, a first threaded tube connected to the bottom end of the pipe connector, an outer tube fixedly connected to the bottom end of the first threaded tube, an inner tube fixedly connected to the inner top surface of the outer tube, a slot being formed through the outer circumference of the inner tube, and an inner sleeve fitting against the inner wall of the inner tube, a sleeve rod fixedly connected to the inner top surface of the inner sleeve, a spring being fitted onto the outer circumference of the sleeve rod, a second threaded tube fixedly connected to the bottom end of the outer tube, a bottom cap threadedly connected to the bottom end of the second threaded tube, and a baffle fixedly connected to the top end of the second threaded tube.

[0009] Preferably, the end of the second inclined sleeve away from the first inclined sleeve is bolted to a branch pipe, one end of the branch pipe is fixedly connected to a main water supply pipe, and one end of the main water supply pipe is bolted to the outlet of the water pump.

[0010] Preferably, a pressure-holding pipe is fixedly connected to the outer circumference of the main water supply pipe, and a pressure-stabilizing tank is threadedly connected to the top end of the pressure-holding pipe.

[0011] Preferably, a horizontal plate is fixedly connected to the outer circumferential surface of the pressure-holding tube, and a support rod is bolted to the lower surface of the horizontal plate near both ends.

[0012] Preferably, the top end of the pipe connector is fixedly connected to the outer circumferential surface of the drip irrigation tape, and the bottom surface of the second spiral tube is provided with a drip outlet.

[0013] Preferably, the top surface of the baffle has a through hole, a sleeve rod is inserted into the hole, the top end of the spring abuts against the inner top surface of the inner sleeve, and the bottom end of the spring abuts against the baffle.

[0014] Compared with the prior art, this utility model provides an irrigation device for millet cultivation, which has the following beneficial effects:

[0015] 1. This utility model can effectively reduce the risk of drip irrigation component blockage. By setting a filter screen inside the second inclined sleeve, it can filter out particulate impurities such as mud and sand in the water, preventing impurities from entering the drip irrigation component and causing blockage. At the same time, the filtered impurities will be deposited in the drain pipe. Turning the cap can discharge the accumulated mud and sand and clean the filter screen, reducing equipment failures caused by blockage, lowering maintenance costs, ensuring the smooth operation of the drip irrigation system, and allowing millet to receive continuous and stable irrigation.

[0016] 2. In this utility model, the pressure stabilizing tank is connected to the main water supply pipe through the pressure-maintaining pipe. When the water pump operates and the water pressure fluctuates or the water pressure distribution is uneven due to the large irrigation area, the pressure stabilizing tank can adjust the pressure. When the water pressure is too high, it stores some water flow, and when the water pressure is too low, it flows back to replenish, so that the drip irrigation tape and each drip irrigation component work under stable water pressure, avoids the drip irrigation amount from fluctuating, and ensures a uniform supply of water required for millet growth.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 An irrigation device for millet cultivation includes a drip irrigation tape 1, one end of which is connected to a first inclined sleeve 2 via a clamp, and one end of the first inclined sleeve 2 is connected to a second inclined sleeve 3 via bolts. A retaining ring 4 is fixedly connected to the inner wall of the second inclined sleeve 3, and a filter screen 5 is connected to the end face of the retaining ring 4 via screws. A drain pipe 6 is fixedly connected to the outer wall of the second inclined sleeve 3, and a screw cap 7 is threaded to the bottom end of the drain pipe 6. Multiple drip irrigation components 8 are fixedly connected at equal intervals on the outer surface of the drip irrigation tape 1.

[0024] The drip irrigation assembly 8 includes a pipe connector 81, a threaded connection of a first screw tube 82 to the bottom end of the pipe connector 81, a fixed connection of an outer tube 83 to the bottom end of the first screw tube 82, a fixed connection of an inner tube 84 to the inner top surface of the outer tube 83, a through slot 85 on the outer circumferential surface of the inner tube 84, and an inner sleeve 86 attached to the inner wall of the inner tube 84, a fixed connection of a sleeve rod 87 to the inner top surface of the inner sleeve 86, a spring 88 sleeved on the outer circumferential surface of the sleeve rod 87, a fixed connection of a second screw tube 89 to the bottom end of the outer tube 83, a threaded connection of a bottom cover 810 to the bottom end of the second screw tube 89, and a fixed connection of a baffle 811 to the top end of the second screw tube 89.

[0025] Specifically, the end of the second inclined sleeve 3 away from the first inclined sleeve 2 is connected to a branch pipe 9 by bolts, one end of the branch pipe 9 is fixedly connected to the main water supply pipe 10, and one end of the main water supply pipe 10 is connected to the outlet of the water pump by bolts.

[0026] The advantage is that by connecting the suction end of the water pump to the suction pipe, which in turn connects to the irrigation water source, the water pump can pump water to the main water supply pipe 10 after starting. The main water supply pipe 10 then sends water into multiple branch pipes 9, which in turn send water into the second inclined sleeve 3. In this way, the water can be filtered out by the filter screen 5 to remove particulate impurities such as mud and sand. Subsequently, the water enters the drip irrigation tape 1 and finally drips out from each drip irrigation component 8, thereby drip irrigating the millet. During this process, the water can be filtered, thus preventing particulate impurities such as mud and sand from entering the drip irrigation components 8, which helps to reduce the risk of blockage in the drip irrigation components 8. At the same time, the mud and sand impurities filtered by the filter screen 5 will be deposited in the drain pipe 6. The accumulated mud and sand can be discharged by rotating the cap 7, and the filter screen 5 can be cleaned.

[0027] Specifically, a pressure-holding pipe 11 is fixedly connected to the outer circumference of the main water supply pipe 10, and a pressure-stabilizing tank 12 is threadedly connected to the top of the pressure-holding pipe 11.

[0028] Specifically, a horizontal plate 13 is fixedly connected to the outer circumference of the pressure-holding pipe 11, and a support rod 14 is bolted to the lower surface of the horizontal plate 13 near both ends.

[0029] The advantage is that several pressure-holding pipes 11 are evenly spaced on the outer circumference of the main water supply pipe 10, and the top of the pressure-holding pipe 11 is threaded to the pressure-stabilizing tank 12. When water pressure fluctuates during the operation of the water pump, or when the water pressure distribution is uneven due to the large irrigation area, the pressure-stabilizing tank 12 can be connected to the main water supply pipe 10 through the pressure-holding pipes 11 and use its internal water storage space to regulate the pressure. When the water pressure is too high, some water can enter the pressure-stabilizing tank 12 for temporary storage to reduce the pressure in the pipeline. When the water pressure is too low, the water in the pressure-stabilizing tank 12 flows back to the main water supply pipe 10 under pressure to replenish the pressure, thereby ensuring that the drip irrigation belt 1 and each drip irrigation component 8 can work under stable water pressure, avoiding the drip irrigation volume from fluctuating due to unstable pressure, and ensuring uniform irrigation in the millet planting area.

[0030] Specifically, the top end of the pipe connector 81 is fixedly connected to the outer circumferential surface of the drip irrigation tape 1, and the bottom surface of the spiral tube 89 is provided with a drip outlet.

[0031] Specifically, a circular hole is provided through the top surface of the baffle 811, into which a sleeve rod 87 is inserted. The top end of the spring 88 abuts against the inner top surface of the inner sleeve 86, and the bottom end of the spring 88 abuts against the baffle 811.

[0032] The advantage is that during irrigation, water flows from the drip irrigation tape 1 through the pipe joint 81 into the screw tube 82, then flows into the gap between the outer tube 83 and the inner tube 84, and then enters the inner tube 84 through the groove 85 on the outer circumference of the inner tube 84. At this time, the water pressure pushes the inner sleeve 86 downward, compressing the spring 88. The inner sleeve 86 slides downward on the inner wall of the inner tube 84, allowing the water to enter the outer tube 83 through the groove 85, and then drips out through the drip outlet on the bottom surface of the screw tube 89 and the bottom cover 810; when When irrigation stops or water pressure decreases, the spring 88 resets and pushes the inner sleeve 86 upward, so that it re-closes tightly against the inner wall of the inner tube 84 to seal the groove 85, thereby preventing external mud and sand from flowing back into the inner tube 84 and the pipeline above through the drip outlet. The advantage of this design is that it can reliably prevent mud and sand in the soil from flowing back into the drip irrigation component 8 due to negative pressure or other reasons during irrigation breaks or when irrigation stops, avoiding mud and sand accumulation and blockage, reducing the frequency of manual cleaning and maintenance, and ensuring the long-term stable operation of the drip irrigation component 8.

[0033] In use, firstly, connect the water pump suction end to the suction pipe and connect it to the irrigation water source. Simultaneously, ensure that the main water supply pipe 10 is connected to the water pump outlet end via bolts, and that the pressure-stabilizing tank 12 is installed at the top of the pressure-holding pipe 11 on the main water supply pipe 10. Insert the support rod 14 into the soil, and use the horizontal plate 13 connected to the support rod 14 to support the pressure-holding pipe 11 and the pressure-stabilizing tank 12. Then, start the water pump; the water source is pumped to the main water supply pipe 10, and then distributed by the main water supply pipe 10 to multiple branch pipes 9. The water flows through the branch pipes 9 into the second inclined sleeve 3, where it is filtered by the filter screen 5 on the retaining ring 4 to remove particulate impurities such as mud and sand before entering the drip irrigation tape 1. The water in the drip irrigation tape 1 flows through the pipe joint 81 into the threaded tube of each drip irrigation component 8. 82, then flows into the gap between the outer pipe 83 and the inner pipe 84, and then enters the inner pipe 84 through the groove 85 on the outer periphery of the inner pipe 84. The water pressure pushes the inner sleeve 86 downward and compresses the spring 88, so that the water can enter the lower part of the outer pipe 83 through the groove 85, and finally drips out through the drip outlet on the bottom surface of the screw tube 89 and the bottom cover 810 to irrigate the millet. During the irrigation process, if the water pressure of the main water supply pipe 10 fluctuates or is unevenly distributed, the pressure stabilizing tank 12 adjusts the pressure through the pressure maintaining pipe 11 to ensure that the drip irrigation belt 1 and the drip irrigation assembly 8 work under stable water pressure. When irrigation stops or the water pressure decreases, the spring 88 resets and pushes the inner sleeve 86 upward to close the groove 85 of the inner pipe 84 and prevent external mud and sand from flowing back and clogging the drip irrigation assembly 8.

[0034] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
