Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation technology, and specifically relates to a porous drip pipe for corn drip irrigation. Background Technology

[0002] Drip irrigation is a precision irrigation technology that delivers water and fertilizer directly to the root zone of crops in small flows and at low frequencies through drippers. Compared to traditional flood irrigation or sprinkler irrigation, drip irrigation significantly reduces water evaporation and seepage, improving water resource utilization. Applying multi-hole drip irrigation technology to corn cultivation can achieve precise water supply, water and fertilizer conservation, increased yield, and improved quality. Traditional extensive agricultural production methods cause serious environmental pollution. Multi-hole drip irrigation for corn can reduce the use of chemical fertilizers and pesticides, reduce agricultural non-point source pollution, protect soil and water resources, and achieve sustainable agricultural development.

[0003] Because the pores of drip irrigation pipes are extremely small, suspended solids, silt, algae, and microorganisms in the water can easily accumulate within the pores after prolonged use, leading to blockages, reduced water flow, or even complete blockage. Blockages can cause uneven water flow from the drip irrigation pipes, or even complete cessation of water flow, resulting in uneven soil moisture and nutrient supply in different areas. Uneven root growth and uneven nutrient absorption in corn affect the overall growth and development of the crop, leading to a decline in yield and quality. Utility Model Content

[0004] In view of this, the present invention provides a porous drip pipe for corn drip irrigation, which can solve the problem of easy clogging of existing corn drip irrigation pipes.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a multi-hole drip irrigation pipe for corn, comprising a water delivery pipe, a branch pipe, a settling chamber, and a connecting assembly. The water delivery pipe is cylindrical and includes a first water delivery pipe and a second water delivery pipe of the same size and shape. The first and second water delivery pipes are respectively disposed on both sides of the branch pipe and fixedly connected to it. Both the first and second water delivery pipes are perpendicular to the branch pipe. The branch pipe is a long and thin tube with multiple small holes evenly distributed on its wall for slowly dripping water to the corn roots. The settling chamber is disposed on the second water delivery pipe. The settling chamber is spherical and its diameter is larger than that of the first water delivery pipe. A drain valve is disposed below the settling chamber, and a guide plate is disposed inside the settling chamber. The connecting assembly is fixed to the end of the first and second water delivery pipes away from the branch pipe, and the connecting assembly is used to connect multiple drip irrigation pipes in series.

[0007] Based on the above technical solution, the multi-hole drip irrigation pipe for corn of this utility model can be further improved as follows:

[0008] The connecting assembly includes a first connector, a second connector, a protrusion, a groove, and an extension tube. The first connector is fixedly connected to the end of the first water supply pipe, and the second connector is fixedly connected to the end of the second water supply pipe. Both the first connector and the second connector are cylindrical structures, and the diameters of the first connector and the second connector are larger than the diameters of the first water supply pipe and the second water supply pipe. The extension tube extends from the inner wall of one end of the second water supply pipe connected to the second connector. The extension tube is inserted into the first water supply pipe of another drip tube for installation. The first connector is provided with the groove, and the second connector is provided with the protrusion. The groove and the protrusion are compatible.

[0009] Both the first and second connectors are provided with through holes for passing bolts.

[0010] Furthermore, the small holes on the wall of the diversion tube are provided with an anti-clogging structure, which is a raised micro-barb made of silicone, used to prevent soil and impurities from entering the small holes and effectively avoid clogging of the dropper.

[0011] Furthermore, the guide plate is spiral-shaped and made of ABS plastic. Its function is to slow down the water flow, enhance the settling effect, and make it easier for impurities in the water to settle to the bottom.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the guide plate is connected to the inner wall of the settling chamber by a suspended shaft, and the spiral structure can guide the water flow to rotate, thus prolonging the residence time of the water in the settling chamber.

[0013] Furthermore, the water pipe is made of PVC.

[0014] Furthermore, the settling chamber is made of transparent acrylic.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are: the deposition of dust / particulate matter in the settling chamber can be directly observed, and the timing of cleaning of the settling chamber can be intuitively determined, avoiding over-cleaning or untimely cleaning.

[0016] Furthermore, the shunt pipe is made of PE.

[0017] Furthermore, the connecting assembly is made of ABS plastic and is used to seal the pipe.

[0018] Furthermore, a filter screen is fixed in the settling chamber, the filter screen is installed on the water flow path, and the filter screen is located at the outlet of the settling chamber.

[0019] Furthermore, the filter screen adopts a double-layer structure, with an outer coarse filter screen and an inner fine filter screen. The coarse filter screen is made of nylon mesh with larger pore size and is used to filter out larger particulate impurities, while the fine filter screen is made of nylon mesh with smaller pore size and is used to filter out smaller particulate impurities, thereby improving the filtration effect.

[0020] Compared with existing technologies, the beneficial effects of the porous drip irrigation pipe for corn provided by this utility model are:

[0021] 1. Setting up a settling chamber can remove most of the suspended solids and silt before the water flows into the drip irrigation system, reducing the risk of clogging and extending the service life of the drip pipes.

[0022] 2. The settling chamber effectively removes suspended solids, silt, and other impurities from the water, improving the water quality entering the drip irrigation system. High-quality water contributes to the normal operation of the drip lines and reduces corrosion and scaling in the system.

[0023] 3. By removing suspended solids and sediment, the settling chamber reduces drip tube clogging and water flow resistance, thereby improving the overall efficiency of the drip irrigation system. This means that water can be distributed more evenly to the crop roots, improving irrigation effectiveness.

[0024] 4. The valve design makes cleaning the dust deposits at the bottom of the settling chamber quick and easy. The dust can be discharged by gravity, saving time and resources.

[0025] 5. If only a portion of the drip irrigation tubing is clogged, only the clogged section needs to be removed and cleaned, without disassembling the entire system. This significantly saves time and effort.

[0026] 6. Because individual pipe sections can be maintained and replaced selectively, the replacement frequency of the entire drip irrigation system can be greatly reduced, thereby lowering maintenance costs. Attached Figure Description

A drain valve 31 is located below the settling chamber 30, and a guide plate 32 is installed inside the settling chamber 30. A connecting component 40 is fixed to the end of the first water pipe 11 and the second water pipe 12 away from the branch pipe 20. The connecting component 40 is used to connect multiple drip tubes in series.

[0033] In the above technical solution, the connecting component 40 includes a first connector 41, a second connector 42, a protrusion 43, a groove 44, and an extension tube 45. The first connector 41 is fixedly connected to the end of the first water supply pipe 11, and the second connector 42 is fixedly connected to the end of the second water supply pipe 12. Both the first connector 41 and the second connector 42 are cylindrical structures. The diameters of the first connector 41 and the second connector 42 are larger than the diameters of the first water supply pipe 11 and the second water supply pipe 12. An extension tube 45 extends from the inner wall of one end of the second water supply pipe 12 connected to the second connector 42. The extension tube 45 is inserted into the first water supply pipe 11 of another drip tube for installation. The first connector 41 is provided with a groove 44, and the second connector 42 is provided with a protrusion 43. The groove 44 and the protrusion 43 are compatible.

[0034] Both the first connector 41 and the second connector 42 are provided with through holes for passing bolts.

[0035] Furthermore, in the above technical solution, the small hole on the wall of the diversion tube 20 is provided with an anti-clogging structure. The anti-clogging structure is a raised micro barb made of silicone, which is used to prevent soil and impurities from entering the small hole and effectively avoid the drip tube from clogging.

[0036] Furthermore, in the above technical solution, the guide plate 32 is spiral-shaped and made of ABS plastic. Its function is to slow down the water flow speed, enhance the settling effect, and make it easier for impurities in the water to settle to the bottom.

[0037] The baffle plate is used to adjust the direction of water flow, preventing the water from directly impacting the walls of the settling chamber or forming eddies, thereby improving sedimentation efficiency.

[0038] Furthermore, in the above technical solution, the water pipe 10 is made of PVC.

[0039] Furthermore, in the above technical solution, the settling chamber 30 is made of transparent acrylic.

[0040] Furthermore, in the above technical solution, the diversion pipe 20 is made of PE.

[0041] Furthermore, in the above technical solution, the connecting component 40 is made of ABS plastic and is used to seal the pipe.

[0042] Furthermore, in the above technical solution, a filter screen is fixed in the settling chamber 30, the filter screen is installed on the water flow path, and the filter screen is set at the outlet of the settling chamber 30.

[0043] Furthermore, in the above technical solution, the filter screen adopts a double-layer structure, with an outer coarse filter screen and an inner fine filter screen. The coarse filter screen is made of nylon mesh with larger pore size and is used to filter out larger particulate impurities, while the fine filter screen is made of nylon mesh with smaller pore size and is used to filter out smaller particulate impurities, thereby improving the filtration effect.

[0044] Before use, first connect the multiple dropper segments end to end, insert the extension tube 45 into the interior of another section of the first water supply pipe 11, slide the protrusion 43 on the second connector 42 into the groove 44 on the other section of the first water supply pipe 11, and fix the connecting assembly 40 of the multiple dropper segments with bolts.

[0045] Water flows through the supply pipe 10 into the distribution pipe 20, where multiple small holes evenly distribute the water to the roots of each corn plant. The settling chamber 30 filters out impurities such as silt and organic matter from the water source. After entering the settling chamber 30, impurities gradually settle to the bottom due to gravity. According to Bernoulli's principle, fluid flows through a large-diameter pipe with low pressure and slow velocity, thus dust gradually accumulates in the settling chamber 30. The drain valve 31 at the bottom of the settling chamber 30 can be opened periodically to discharge the settled impurities, ensuring smooth water flow.

[0046] When stains accumulate on the filter screen, the water supply can be turned off, the entire drip tube can be removed, and water can be drawn from the first water supply pipe 11 to backwash the filter screen.

[0047] Specifically, the principle of this utility model is as follows: Before use, the multiple segments of the dropper are connected end to end, the extension tube 45 is inserted into the interior of another segment of the first water supply pipe 11, the protrusion 43 on the second connector 42 slides into the groove 44 on the other segment of the first water supply pipe 11, and the connecting assembly 40 of the multiple segments of the dropper is fixed by bolts.

[0048] Water flows through the supply pipe 10 into the distribution pipe 20, where multiple small holes evenly distribute the water to the roots of each corn plant. The settling chamber 30 filters out impurities such as silt and organic matter from the water source. After entering the settling chamber 30, impurities gradually settle to the bottom due to gravity.

The drain valve 31 at the bottom of the settling chamber 30 can be opened periodically to discharge the settled impurities, ensuring smooth water flow.

[0049] When stains accumulate on the filter screen, the water supply can be turned off, the entire drip tube can be removed, and water can be drawn from the first water supply pipe 11 to backwash the filter screen.
