Description

Technical Field

[0001] The utility model relates to a drip irrigation device, in particular to an anti-clogging drip irrigation device for the Yellow River irrigation area, belonging to the technical field of agricultural drip irrigation equipment. Background Art

[0002] The Yellow River Irrigation Area refers to an area where crops are irrigated by introducing water from the Yellow River. When irrigating crops, drip irrigation is often used to improve the utilization of water resources. The drip irrigation device used mainly buries the drip pipe underground or installs the drip pipe above the soil, and drills small holes for drip irrigation in places where irrigation is needed, so as to achieve the purpose of saving water and energy. However, this type of drip irrigation device is usually blocked by the backflow of external sediment, or by the roots of plants extending into the small holes of the water outlet, which affects the service life of the drip irrigation pipe and is inconvenient to use. In addition, the water resource used in the Yellow River Irrigation Area is the Yellow River water, which contains more sediment, so it is more likely to cause blockage of the drip irrigation device during drip irrigation.

[0003] In the prior art, there is an anti-clogging drip irrigation system for the Yellow River irrigation area disclosed in announcement number CN215122847U, which detects the sand content in the clear water tank water through a sand content detection module. If the sand content is higher than a preset value, the Yellow River water circulates through pipeline I to the primary sedimentation tank for further sedimentation and filtration. When the sand content in the clear water tank is less than the preset value, the control system controls the Yellow River water to be transported to the drip irrigation system to ensure that the drip irrigation system is not blocked. The prior art is also an anti-clogging optimization measure for the drip irrigation equipment used in the Yellow River irrigation area, but the prior art only purifies the Yellow River water from the source. This method requires the construction of special sedimentation tanks and filtration tanks, which will result in a large overall engineering workload and cannot be well promoted and used. Moreover, it is only for filtering the output water source and cannot prevent blockage caused by external sediment. The agricultural energy-saving and anti-clogging drip irrigation device disclosed in announcement number CN207665696U, through The thermostat can automatically turn off the electric heating plate when the water temperature reaches the set value, and the stainless steel filter can filter impurities from entering the pipeline. When the first pipeline is blocked, the pipe cover is opened, and the switch is turned on to make the optional motor work normally. The blockage is screwed out of the first pipeline through the screw with a spiral sheet on the surface, and the water source is transported to the second pipeline through the first pipeline. The water source is transported to various areas of the farmland through the liquid guide pipes on both sides of the second pipeline. The farmland is irrigated on a large scale through the water outlet holes on the surface of the liquid guide pipe. The filter provided at the liquid guide pipe and the water outlet of the second pipeline can prevent the blockage of the drip irrigation pipe caused by the reflux of external sediment. However, in actual use, since the drip irrigation holes are often relatively small, a filter needs to be set. If the mesh diameter is large, it cannot prevent the blockage of the drip irrigation pipe caused by the reflux of external sediment. If the mesh is small, it is completely possible to directly open a smaller drip irrigation hole, that is, a more ideal anti-blocking effect cannot be achieved by setting a filter.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, a Yellow River irrigation area anti-clogging drip irrigation device comprises a main water supply pipe 1 and a drip irrigation capillary 2, wherein a plurality of drip irrigation capillary 2 are provided, and the drip irrigation capillary 2 is connected to the pipe body of the main water supply pipe 1, and a plurality of drip irrigation drippers 3 are connected to the pipe body of the drip irrigation capillary 2, and a water storage flushing tank 4 is connected to one end of the pipe body of the main water supply pipe 1. By laying the main water supply pipe 1 and the drip irrigation capillary 2 in the Yellow River irrigation area, the irrigation water resources of the Yellow River can be respectively transported to the drip irrigation capillary 2 through the main water supply pipe 1, and then The Yellow River water for irrigation is then dripped at a uniform speed through the drip irrigation dripper 3, so that the crops planted in the Yellow River irrigation area can be drip-irrigated and watered, and part of the Yellow River water can be transported to the water storage flushing tank 4 through the main water supply pipe 1 for storage. When the drip irrigation is completed, the main water supply pipe 1 can be flushed with the water stored in the water storage flushing tank 4, so as to avoid the sediment contained in the Yellow River water from silting up in the pipe, thereby avoiding the blockage of the main water supply pipe 1 caused by long-term use;

[0032] A filter plate 15 is connected to the main water supply pipe 1, a conical inner cavity 32 is provided in the drip irrigation dripper 3, and a conical blocking block 36 is movably inserted in the conical inner cavity 32. The Yellow River water entering the main water supply pipe 1 can be filtered through the filter plate 15 to prevent the silt impurities in the water from clogging the drip irrigation dripper 3 when drip irrigation is performed through the drip irrigation dripper 3. The conical blocking block 36 can also block the conical inner cavity 32 to prevent the external impurities from clogging the drip irrigation dripper 3, so that the drip irrigation device has a dual anti-clogging function, and there is no need to build a special filter tank, and the filtering and transportation can be combined together, which greatly reduces the laying cost of the irrigation device and is convenient for promotion and use.

[0033] A water storage and flushing tank 4 is connected to the main water supply pipe 1 via a water storage pipe 41 and a flushing pipe 42. One end of the water storage pipe 41 inserted in the main water supply pipe 1 is located above the filter plate 15, and one end of the flushing pipe 42 inserted in the main water supply pipe 1 is located below the filter plate 15. During the water storage stage, the filtered Yellow River water can be stored through the water storage pipe 41. During the flushing stage, the bottom end of the inner wall of the main water supply pipe 1 is flushed through the flushing pipe 42 to flush away the silt deposited at the bottom end of the inner wall, thereby completing the flushing of the main water supply pipe 1.

[0034] Embodiment 2

[0035] Improvements based on Example 1:

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, one end of the main water supply pipe 1 is connected to the water inlet pipe 11, and the other end of the water inlet pipe 11 is connected to the external high-pressure delivery pump, and the other end of the main water supply pipe 1 is connected to the sewage pipe 12. A water inlet ball valve 13 is installed on the pipe body of the water inlet pipe 11, and a sewage gate valve 14 is installed on the pipe body of the sewage pipe 12. The Yellow River water for drip irrigation can be conveniently transported to the main water supply pipe 1 through the water inlet pipe 11, and the sewage with silt in the main water supply pipe 1 can be discharged through the sewage pipe 12. The water inlet ball valve 13 and the sewage gate valve 14 can respectively control the opening and closing of the water inlet pipe 11 and the sewage pipe 12, thereby facilitating the operation of the drip irrigation device.

[0037] Furthermore, the cross-section of the sewage pipe 12 is semicircular, and the connection positions of the water inlet pipe 11 and the sewage pipe 12 at both ends of the main water supply pipe 1 are located below the installation position of the filter plate 15, which can ensure that when the Yellow River water for drip irrigation is introduced into the main water supply pipe 1, the Yellow River water can be passed into the lower part of the filter plate 15, thereby ensuring that the filter plate 15 filters the Yellow River water. At the same time, when the main water supply pipe 1 is flushed, it can be ensured that the flushing water with mud and sand can only flow out from below the filter plate 15.

[0038] Furthermore, a drip irrigation ball valve 21 is installed on the pipe body of the drip irrigation tube 2 at one end close to the main water supply pipe 1, and the drip irrigation drippers 3 are evenly distributed on the pipe body of the drip irrigation tube 2, and the drip irrigation ends of the drip irrigation drippers 3 are vertically downward. The opening and closing of each drip irrigation tube 2 can be individually controlled by the drip irrigation ball valve 21, and when the drip irrigation tube 2 is in a conducting state, multiple drip irrigation drippers 3 can evenly drip irrigate the crops planted in the Yellow River irrigation area.

[0039] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the drip irrigation dripper 3 also includes a hydraulic pushing component and a dripper shell 31. The hydraulic pushing component is arranged in the conical inner cavity 32. The hydraulic pushing component is connected to the upper end of the conical sealing block 36. The conical sealing block 36 is tightly attached to the inner wall of the bottom end of the conical inner cavity 32. A drip irrigation hole 39 is opened at the bottom end of the drip irrigation shell 31. The drip irrigation hole 39 is connected to the conical inner cavity 32. When the drip irrigation water in the drip irrigation capillary 2 enters the conical inner cavity 32 of the drip irrigation dripper 3, the conical sealing block 36 blocks the bottom end of the conical inner cavity 32. At this time, the drip irrigation water cannot The conical surface sealing block 36 is pushed upward by the hydraulic jacking assembly as the drip irrigation water continues to enter, thereby leaving a gap between the conical surface sealing block 36 and the inner wall of the conical inner cavity 32, so that the drip irrigation water can drip out from the drip irrigation hole 39 through the gap, that is, the drip irrigation operation can be realized, and when the drip irrigation is finished, the hydraulic jacking assembly can push the conical surface sealing block 36 back to the initial position again, thereby blocking the bottom end of the conical inner cavity 32, preventing foreign matter from entering the conical inner cavity 32, and thus preventing the drip irrigation dripper from being blocked.

[0040] Furthermore, the hydraulic push assembly includes a dripper inner shell 33, an inner shell piston 34, a push rod 35, an inner shell spring 37 and a positioning connecting rod 38. The dripper inner shell 33 is fixedly connected to the conical inner cavity 32 through the positioning connecting rod 38. The inner shell piston 34 is movably clamped in the inner cavity of the dripper inner shell 33. The inner cavity of the dripper inner shell 33 is also provided with an inner shell spring 37. The inner shell spring 37 is tightly attached to the upper part of the inner shell piston 34. The push rod 35 is connected between the inner shell piston 34 and the conical surface blocking block 36, and the horizontal cross-sectional area of ​​the inner shell piston 34 is larger than the horizontal cross-sectional area of ​​the conical surface blocking block 36. When the drip irrigation water enters When inside the conical inner cavity 32, since the water pressure is constant, the force received is different according to the different force-bearing areas. Therefore, the inner shell piston 34 can be pushed upward by the water pressure, so that the conical sealing block 36 is separated from the inner wall of the bottom end of the conical inner cavity 32, which is convenient for drip irrigation water to drip out. The inner shell piston 34 is pushed upward, which compresses the inner shell spring 37 and has elastic force. Therefore, when the drip irrigation ends and the water pressure is lost, the conical sealing block 36 can be pushed back to the initial position again under the action of the elastic force of the inner shell spring 37, thereby blocking the bottom end of the conical inner cavity 32.

[0041] Furthermore, the bottom end of the conical sealing block 36 is integrally connected with a sealing needle 310, and the sealing needle 310 is movably inserted in the drip hole 39. When the conical sealing block 36 seals the bottom end of the conical inner cavity 32, the sealing needle 310 can be inserted in the drip hole 39, that is, it can prevent external debris from entering the drip hole 39, which can further improve the anti-clogging effect of the drip irrigation dripper 3.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, the upper ends of the water storage pipe 41 and the flushing pipe 42 are connected with a three-way ball valve 43, and the other end of the three-way ball valve 43 is connected to the bottom of the water storage flushing tank 4. The three pipe interfaces of the three-way ball valve 43 are respectively connected to the water storage pipe 41, the flushing pipe 42 and the water storage flushing tank 4. The water storage pipe 41 and the water storage flushing tank 4 are in a connected state through the three-way ball valve 43. When the flushing pipe 42 and the water storage flushing tank 4 are in a closed state, the filtered Yellow River drip irrigation water can be accumulated in the water storage flushing tank 4. In the brush tank 4, the water storage pipe 41 and the water storage flushing tank 4 are in a closed state through the three-way ball valve 43. When the flushing pipe 42 and the water storage flushing tank 4 are in a connected state, the drip irrigation water accumulated in the water storage flushing tank 4 can flow out from the flushing pipe 42, thereby flushing the inner wall of the bottom end of the main water supply pipe 1, that is, the deposited mud and debris can be taken away from the sewage pipe 12, thereby cleaning the main water supply pipe 1, so as to avoid a lot of mud and sand deposited in the main water supply pipe 1 due to long-term use and cause blockage in the pipe.

[0043] Furthermore, a tank piston 44 and a tank spring 45 are provided in the water storage and flushing tank 4. The tank piston 44 is movably connected to the inner wall of the water storage and flushing tank 4, and the tank spring 45 is connected to the upper end of the tank piston 4. When drip irrigation water accumulates in the water storage and flushing tank 4, the tank piston 44 can be pushed upward, and the tank spring 45 can be compressed and deformed, that is, the accumulated water in the water storage and flushing tank 4 can have a higher water pressure. Therefore, when it is necessary to flush the main water supply pipe 1 through the flushing pipe 42, a faster flushing water flow can be formed to thoroughly flush the inner wall of the bottom end of the main water supply pipe 1.

[0044] Working principle: The irrigation water resources of the Yellow River are respectively transported to the drip irrigation tube 2 through the main water supply pipe 1, and then the Yellow River water for irrigation is dripped at a uniform speed through the drip irrigation dripper 3. When the drip irrigation water enters the conical inner cavity 32, since the water pressure is constant, the force received is different according to the different force-bearing areas. Therefore, the inner shell piston 34 can be pushed upward by the action of the water pressure, so that the conical sealing block 36 is separated from the inner wall of the bottom end of the conical inner cavity 32, which can facilitate the dripping of the drip irrigation water. The inner shell piston 34 is pushed upward, which will cause the inner shell spring 37 to be compressed and have elastic force. Therefore, when the drip irrigation ends and the water pressure is lost, the conical sealing block 36 can be pushed back to its original position again under the action of the elastic force of the inner shell spring 37. The starting position forms a blockage on the bottom end of the conical inner cavity 32, and part of the Yellow River water can be transported to the water storage and flushing tank 4 through the main water supply pipe 1 for storage. After the drip irrigation is completed, the main water supply pipe 1 can be flushed by the water stored in the water storage and flushing tank 4, and the drip irrigation water accumulated in the water storage and flushing tank 4 can flow out from the flushing pipe 42, so as to flush the inner wall of the bottom end of the main water supply pipe 1, that is, the deposited silt and debris can be taken away from the sewage pipe 12, so as to clean the main water supply pipe 1, so as to avoid the deposition of more silt in the main water supply pipe 1 after long-term use and cause blockage in the pipe, so as to avoid the silt contained in the Yellow River water from causing siltation in the pipe, so as to avoid the blockage of the main water supply pipe 1 due to long-term use.
