Description

Technical Field

[0001] The invention belongs to the technical field of drip irrigation, and in particular relates to an anti-blocking drip irrigation head used for underground drip irrigation in saline-alkali land. Background Art

[0002] Saline-alkali land mainly refers to salinized soil with high chloride or sulfate content, which is common in arid and semi-arid areas. Specifically, the soil salt content and pH value are high, and the soil is alkaline; the soil organic matter content is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations that are harmful to crops, making it difficult for crops to grow. The fundamental reason for salinization is the accumulation of salt and alkali in the surface soil caused by the imbalance of water and salt regulation.

[0003] Drip irrigation is an effective way to irrigate arid saline-alkali land. Existing drip irrigation devices are generally laid on the ground surface and are suitable for planting crops that are only harvested once a year. However, when planting annual crops that are cut multiple times, in order to avoid mechanical damage during harvesting, the drip irrigation device is required to be laid 10-30cm underground.

[0004] However, the drip irrigation device laid underground is very easy to be blocked by underground sediment. At the same time, when there are large particles of solid impurities in the water source, it will also cause the dripper and the internal flow channel of the dripper to be blocked. When the water source is cut off, the pressure compensation will also cause the external sediment to flow back, causing the dripper to be wrapped and blocked by sediment. Long-term accumulation will also cause the drip irrigation pipe and drip irrigation belt to be blocked.

[0005] Due to the occurrence of the above situation, the drip irrigation device often needs maintenance and replacement, which consumes a lot of manpower and material resources. If the maintenance is not timely, it will cause the plants or seeds to die due to lack of water. Therefore, it is necessary to redesign the anti-blocking design of the conventional drip irrigation head. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention is provided with a body, a capillary hole, a rubber ring, an adjusting frame, a connecting rod, a tympanic membrane, a baffle, a rubber plate, an arc-shaped portion, a water outlet, a silicone plate and a cross-shaped portion, wherein the rubber ring fits with the inner wall of the body, the rubber ring is slidably connected with the body, the rubber ring is fixedly connected with the adjusting frame, the connecting rod is fixedly connected with the adjusting frame, and the silicone plate is recessed toward the outside of the body, so that when the body is connected to the water inlet to take in water, when the weight of the incoming water reaches the moving weight, the tympanic membrane will be pressed downward, the tympanic membrane will drive the connecting rod downward, the connecting rod will drive the adjusting frame to move downward, and at the same time drive the rubber ring downward, the rubber ring will move away from the capillary hole, and the water will flow out along the capillary hole. Since the rubber ring fits with the inner wall of the body, the water will not flow into the capillary hole along the gap, and will then be blocked by the rubber plate of the baffle on the outside. When the water pressure is sufficient, the rubber plate will be pushed to expand, the water will flow out along the rubber plate, and then the water will flow in The water accumulates at the bottom of the body. When it accumulates to a certain extent, the internal pressure is high, and the water flows along the silicone plate. The water flows out along the cross-mouth to the outside of the body for drip irrigation. When in use, since the pressure inside the device is greater than the external pressure as a whole, it is not easy for mud to enter the body. When the drip irrigation is stopped, the internal pressure of the body decreases and the silicone plate closes. At this time, the pressure generated by the external sewage mixture is not enough to push the silicone plate inward to expand. Therefore, most of the returned sewage cannot enter the body. However, when the internal pressure of the body decreases, part of the sewage mixture will still enter the body. At this time, the rubber plate inside the body will close again, and the tympanic membrane will rebound upward, driving the connecting rod to move upward, driving the adjusting frame to move upward, and driving the rubber ring to move upward at the same time, blocking the capillary pores. At this time, both ends of the capillary pores are blocked, and sewage cannot enter the capillary pores, thereby achieving an anti-blocking effect.

[0017] 2. The present invention provides a sealing cover, a threaded ring and a threaded tube. When it is necessary to clean or replace parts in the main body, the bottom of the main body can be opened by rotating the threaded cover, and then the eardrum and other parts can be cleaned or replaced by rotating the threaded tube, and the internal silicone plate can be removed by the threaded tube.

[0018] 3. The present invention provides a raised portion, an elastic steel ring, a reduced portion and a recessed portion, so that the eardrum can be deformed along the recessed portion when pressure is applied to the eardrum. Subsequently, the reduced portion at one end of the elastic steel sheet can be slightly deformed to prevent the eardrum from falling off when the eardrum is deformed. At the same time, the eardrum can be limited by the raised portion, and the raised portion can also play a sealing role.

[0019] 4. The present invention provides a card slot, an insertion portion, an inclined portion and a clamping portion, so that the insertion portion can be placed into the card slot along the inclined portion, and under the action of the clamping portion, the rubber sheet will not fall off from the card slot without applying too much force, which is convenient for installation, disassembly and replacement.

[0020] 5. The present invention can prevent excessive mud from directly blocking the water outlet by arranging a fan-shaped frame, thereby forming a layer of protection for the capillary pores.

DETAILED DESCRIPTION

[0032] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0033] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 7 As shown, an anti-blocking drip irrigation head for underground drip irrigation in saline-alkali land provided by an embodiment of the present invention comprises a drip irrigation head body 1 and an anti-blocking component for preventing the body 1 from being blocked, wherein the anti-blocking component comprises a plurality of capillaries 2 arranged on one side of the body 1, a rubber ring 3 arranged on one side of the capillary pores 2, an adjusting frame 4 arranged on one side of the rubber ring 3, a connecting rod 5 arranged on one side of the adjusting frame 4, a tympanic membrane 6 arranged at one end of the connecting rod 5, a baffle 7 arranged on one side of the capillary pores 2, a rubber plate 8 arranged at one end of the baffle 7, an arc-shaped portion 9 arranged on one side of the rubber plate 8, a plurality of water outlets 10 arranged on the outside of the body 1, a silicone plate 11 arranged on one side of the water outlet 10, and a cross 12 arranged on one side of the silicone plate 11, wherein the rubber ring 3 is fitted with the inner wall of the body 1, the rubber ring 3 is slidably connected to the body 1, the rubber ring 3 is fixedly connected to the adjusting frame 4, the connecting rod 5 is fixedly connected to the adjusting frame 4, and the silicone plate 11 is recessed toward the outside of the body 1.

[0035] The above scheme is adopted: by arranging the main body 1, the capillary pores 2, the rubber ring 3, the adjustment frame 4, the connecting rod 5, the eardrum 6, the baffle 7, the rubber plate 8, the arc portion 9, the water outlet 10, the silicone plate 11 and the cross mouth 12, the rubber ring 3 is fitted with the inner wall of the main body 1, the rubber ring 3 is slidably connected to the main body 1, the rubber ring 3 is fixedly connected to the adjustment frame 4, the connecting rod 5 is fixedly connected to the adjustment frame 4, and the silicone plate 11 is recessed toward the outside of the main body 1, so that when the main body 1 is connected to the water inlet, the water inlet When water enters, when the weight of the water entering reaches the moving weight, it will press the tympanic membrane 6 downward, the tympanic membrane 6 drives the connecting rod 5 downward, the connecting rod 5 drives the adjusting frame 4 to move downward, and at the same time drives the rubber ring 3 to move downward, the rubber ring 3 is away from the capillary pore 2, and the water flows out along the capillary pore 2. Since the rubber ring 3 fits the inner wall of the body 1, the water flow will not flow into the capillary pore 2 along the gap, and then be blocked by the rubber plate 8 of the outer baffle 7. When the water flow pressure is sufficient, the rubber plate 8 is pushed to expand, and the water flows along the rubber When the water accumulates to a certain extent, the internal pressure is high, the water flows along the silicone plate 11, and the water flows along the cross-mouth 12 to the outside of the main body 1 for drip irrigation. When in use, since the pressure inside the device is greater than the external pressure as a whole, it is not easy for soil to enter the main body 1. When the drip irrigation is stopped, the internal pressure of the main body 1 decreases, and the silicone plate 11 is closed. At this time, the pressure generated by the external sewage mixture is not enough to push the silicone plate 11 inward to expand, so most of the sewage that flows back cannot enter the main body 1. However, when the internal pressure of the main body 1 decreases, part of the sewage mixture will still enter the main body 1, and at this time, the rubber plate 8 inside the main body 1 will close again, and the tympanic membrane 6 will rebound upward, driving the connecting rod 5 to move upward, driving the adjusting frame 4 to move upward, and at the same time driving the rubber ring 3 to move upward, blocking the capillary 2. At this time, both ends of the capillary pore 2 are blocked, and the sewage cannot enter the capillary pore 2, thereby achieving an anti-blocking effect.

The threaded tube 15, the threaded ring 14 and the sealing cover 13 are threadedly connected to the body 1.

[0037] By adopting the above scheme: by setting the sealing cover 13, the threaded ring 14 and the threaded tube 15, when the parts in the main body 1 need to be cleaned or replaced, the bottom of the main body 1 can be opened by rotating the threaded cover, and then the eardrum 6 and other parts can be cleaned or replaced by rotating the threaded tube 15, and the internal silicone plate 11 can be removed by the threaded tube 15.

[0038] refer to Figure 5A protrusion 16 is provided on one side of the eardrum 6, an elastic steel ring 17 is provided on one side of the protrusion 16, a reduction portion 18 is provided on one side of the elastic steel ring 17, and a recess 19 is provided on one side of the eardrum 6.

[0039] The above scheme is adopted: by setting the protrusion 16, the elastic steel ring 17, the reduction portion 18 and the recessed portion 19, the eardrum 6 can be deformed along the recessed portion 19 when the eardrum 6 is subjected to pressure, and then the reduction portion 18 at one end of the elastic steel sheet can be slightly deformed to prevent the eardrum 6 from falling off when it is deformed. At the same time, the eardrum 6 can be limited by the action of the protrusion 16, and the protrusion 16 can also play a sealing role.

[0040] refer to Figure 6 A slot 20 is provided on one side of the rubber plate 8, an inserting portion 21 is provided on one side of the rubber plate 8, an inclined portion 22 is provided on one side of the inserting portion 21, and a clamping portion 23 is provided on one side of the inclined portion 22.

[0042] refer to Figure 1 A fan-shaped frame 24 is provided on the outside of the main body 1 , and the fan-shaped frame 24 is fixedly connected to the main body 1 .

[0043] The above solution is adopted: by providing the fan-shaped frame 24 , it is possible to prevent excessive mud from directly blocking the water outlet 10 .

[0044] refer to Figure 4 A guide portion 25 is provided on one side of the water outlet 10 .

[0045] By adopting the above solution, the mud-water mixture at the water outlet 10 can be guided by providing the guide portion 25 .

[0046] refer to Figure 4 The capillary pores 2 are provided in three groups.

[0047] By adopting the above solution, the water output of the capillary pores 2 can be increased by providing three groups of capillary pores 2 .

[0048] refer to Figure 4 A sealing gasket 26 is provided on one side of the sealing cover 13 .

[0049] By adopting the above solution, the main body 1 can be sealed by providing the sealing gasket 26 to prevent water from flowing out from the bottom of the main body 1.

[0050] When in use, first, when the body 1 is connected to the water inlet and water enters, when the weight of the incoming water reaches the moving weight, the tympanic membrane 6 will be pressed downward, the tympanic membrane 6 will drive the connecting rod 5 downward, the connecting rod 5 will drive the adjusting frame 4 to move downward, and at the same time drive the rubber ring 3 to move downward, the rubber ring 3 will be away from the capillary pore 2, and the water will flow out along the capillary pore 2. Since the rubber ring 3 fits the inner wall of the body 1, the water will not flow into the capillary pore 2 along the gap, and in the process of the tympanic membrane 6 being deformed, the shrinking part 18 at one end of the elastic steel sheet can be slightly The rubber sheet 8 of the outer baffle 7 is then blocked by the rubber sheet 8. When the water flow pressure is sufficient, the rubber sheet 8 is pushed to expand, and the water flows out along the rubber sheet 8. Then the water flows accumulate at the bottom of the body 1. When the accumulation reaches a certain level, the internal pressure is high, and the water flows along the silicone sheet 11. The water flows out along the cross mouth 12 to the outside of the body 1. Drip irrigation is carried out on the side, and when in use, since the pressure inside the device is generally greater than the external pressure, it is not easy for soil to enter the body 1. When drip irrigation is stopped, the internal pressure of the body 1 decreases, and the silicone plate 11 is closed. At this time, the pressure generated by the external sewage mixture is not enough to push the silicone plate 11 inward to expand, so most of the refluxed sewage cannot enter the body 1, but when the internal pressure of the body 1 decreases, part of the sewage mixture will still enter the body 1, and at this time, the rubber plate 8 inside the body 1 will close again, and the tympanic membrane 6 will rebound upward, driving the connecting rod 5 to move upward, driving the adjusting frame 4 to move upward, and driving the rubber ring 3 to move upward to block the capillary 2. At this time, both ends of the capillary pore 2 are blocked, and sewage cannot enter the capillary pore 2, thereby achieving an anti-blocking effect. When used for a long time and it is necessary to replace or clean the internal parts, the bottom of the body 1 can be opened by rotating the threaded cover, and then the parts such as the girdle can be cleaned and replaced by rotating the threaded tube 15, and the silicone plate 11 can be removed by rotating the threaded tube 15.
