Description

Technical Field

[0001] The present invention relates to the technical field of drip irrigation systems, and more particularly, to a drip irrigation system for camellia oleifera trees. Background Art

[0002] Camellia oleifera is one of the four major woody oil plants in the world. It grows in the mountains and hilly areas of the subtropical regions in southern China and is a unique natural high-grade oil in China.

[0003] In order to ensure sufficient water for the cultivation of camellia oleifera, a drip irrigation system is used to supply water to the camellia oleifera. However, the existing drip irrigation systems have strict requirements on the water quality of the water source, and generally need to be filtered, and sometimes even need to be precipitated and chemically treated. The areas where camellia oleifera is planted are mostly mountainous and hilly areas, and it is inconvenient to transport the water used for drip irrigation. Only the water source can be found nearby for drip irrigation. The water sources in mountainous and hilly areas are mostly accumulated water, and the accumulated water contains a large amount of sediment. Filtering or / and precipitating and chemically treating the accumulated water will undoubtedly increase the planting cost and reduce the planting income. However, the sediment in the accumulated water is extremely likely to cause the network pipes of the existing drip irrigation system to be blocked. Seriously, it will make the entire drip irrigation system unable to work properly or even be scrapped, resulting in very little benefit from using the drip irrigation system to supply water to the camellia oleifera. Therefore, there is a need to realize drip irrigation using water sources containing sediment.

[0004] Therefore, how to realize drip irrigation using water sources containing sediment is an urgent problem to be solved in the technical field. Summary of the Invention

[0043] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0044] As Figure 1 - Figure 2 shown, this embodiment provides an oil tea tree drip irrigation system, including:

[0045] A head hub 1, which is used to connect to a water source for transportation;

[0046] A drip irrigation pipe network 2, which includes a main pipe 21. The main pipe 21 is connected to the output end of the head hub 1. A plurality of branch pipes 22 are connected to the main pipe 21 in a communicating manner. A plurality of spiral drip irrigation pipes 23 are connected to the branch pipes 22 in a communicating manner. The diameter of the spiral drip irrigation pipe 23 is smaller than the diameter of the branch pipe 22. A plurality of drip irrigation holes are symmetrically opened on the spiral drip irrigation pipe 23. The spiral drip irrigation pipe 23 is used for drip irrigation of the roots of the oil tea trees.

[0047] A sewage discharge mechanism 3, the input end of the sewage discharge mechanism 3 is communicated with the end of the branch pipe 22, the output end of the sewage discharge mechanism 3 is communicated with a water source, and the sewage discharge mechanism 3 is used to return the slag entering the branch pipe 22 to the water source through the water flow.

[0048] It can be understood that when drip irrigation is carried out on the oil tea trees, the head hub 1 extracts the water source in the oil tea tree planting area, conveys the water into the main pipe 21, and the main pipe 21 then guides and conveys the water to a plurality of branch pipes 22. The branch pipes 22 then guide and convey the water to a plurality of spiral drip irrigation pipes 23. The water entering the spiral drip irrigation pipes 23 seeps out through a plurality of drip holes to carry out drip irrigation on the roots of the oil tea trees. After the slag in the water source flows through the main pipe 21 and enters a plurality of branch pipes 22, since the diameter of the spiral drip irrigation pipe 23 is smaller than that of the branch pipe 22, the water flow rate in the branch pipe 22 is greater than the water flow rate in the spiral drip irrigation pipe 23, making it difficult for the slag in the water flow in the branch pipe 22 to enter the spiral drip irrigation pipe 23. The slag in the branch pipe 22 is pushed into the sewage discharge mechanism 3 by the water flow, and then through the guiding and conveying of the sewage discharge mechanism 3, the slag is pushed back to the water source through the water flow, thereby avoiding the blockage of the drip irrigation pipe network 2 by the slag; in this technical solution, the water source in the oil tea tree planting area is extracted by the head hub 1, conveyed into the drip irrigation pipe network 2 to carry out drip irrigation on the roots of the oil tea trees, and by setting the diameter of the spiral drip irrigation pipe 23 to be smaller than that of the branch pipe 22, it is difficult for the slag in the water flow in the branch pipe 22 to enter the spiral drip irrigation pipe 23. The slag in the branch pipe 22 is pushed into the sewage discharge mechanism 3 by the water flow, and then through the guiding and conveying of the sewage discharge mechanism 3, the slag is pushed back to the water source through the water flow, thereby avoiding the blockage of the drip irrigation pipe network 2 by the slag, realizing the drip irrigation with the water source containing slag, and improving the benefit of the drip irrigation system in supplying water to the oil tea trees.

[0049] It should be noted that the spiral drip irrigation pipe 23 is buried in the ground where the oil tea trees are planted. The middle position of the spiral drip irrigation pipe 23 is arranged corresponding to the main trunk of the oil tea tree, and the multi-turn pipe sections of the spiral drip irrigation pipe 23 are arranged to extend downward step by step from the inside to the outside; through such a setting method, the drip irrigation range of the spiral drip irrigation pipe 23 extends downward step by step from the inside to the outside, and due to the hydrotropism of the roots of the oil tea trees, the roots of the oil tea trees grow downward step by step from the inside to the outside according to the drip irrigation range of the spiral drip irrigation pipe 23, enabling the roots of the oil tea trees to establish a stable connection with the soil and avoiding the occurrence of lodging caused by strong wind weather or the fruit hanging on the branches of the oil tea trees.

[0050] As Figure 2 shown, the sewage discharge mechanism 3 includes:

[0051] A sewage discharge pipe 31, a plurality of return pipes I 32 are connected and arranged on the sewage discharge pipe 31, and the output end of the sewage discharge pipe 31 is communicated with a water source;

[0052] U-shaped tube 33, one end of the U-shaped tube 33 is communicated with the end of the branch pipe 22;

[0053] Water pressure maintaining assembly I 34, one end of the water pressure maintaining assembly I 34 is communicated with the return pipe I 32, the other end of the water pressure maintaining assembly I 34 is communicated with the other end of the U-shaped tube 33, and the water pressure maintaining assembly I 34 is used to guide the dregs to enter the return pipe I 32 along with the water flow and maintain the water pressure in the branch pipe 22.

[0054] It can be understood that after the water flow and dregs in the branch pipe 22 flow to the end of the branch pipe 22, they are guided by the U-shaped tube 33 into the water pressure maintaining assembly I 34. The flow rate at the end of the branch pipe 22 is regulated by the water pressure maintaining assembly I 34, so that the water pressure in the branch pipe 22 can be maintained at the required value, ensuring that the water flow in the branch pipe 22 can smoothly enter the spiral drip irrigation pipe 23, and the dregs in the branch pipe 22 are pushed into the water pressure maintaining assembly I 34 along with the water flow. The water flow containing dregs enters the sewage pipe 31 after flowing through the return pipe I 32, and then is centrally returned to the water source through the sewage pipe 31.

[0055] As Figure 3 shown, a plurality of return pipes II 35 are communicated with the return pipe I 32. One end of the water pressure maintaining assembly II 36 is communicated with the return pipe II 35, and the other end of the water pressure maintaining assembly II 36 is communicated with the end of the spiral drip irrigation pipe 23. The water pressure maintaining assembly II 36 has the same structure as the water pressure maintaining assembly I 34.

[0056] It can be understood that by setting the diameter of the spiral drip irrigation pipe 23 to be smaller than that of the branch pipe 22, it is difficult for the dregs in the water flow in the branch pipe 22 to enter the spiral drip irrigation pipe 23; however, fine dregs will still enter the spiral drip irrigation pipe 23 along with the water flow. The accumulation of fine dregs in the spiral drip irrigation pipe 23 will cause blockage of the spiral drip irrigation pipe 23. Therefore, a plurality of return pipes II 35 are communicated with the return pipe I 32. The return pipe II 35 is communicated with the end of the spiral drip irrigation pipe 23 through the water pressure maintaining assembly II 36. The water pressure maintaining assembly II 36 regulates the flow rate at the end of the spiral drip irrigation pipe 23, so that the water pressure in the spiral drip irrigation pipe 23 can be maintained at the required value, ensuring that the water in the spiral drip irrigation pipe 23 can seep out through a plurality of drip holes. The fine dregs entering the spiral drip irrigation pipe 23 are pushed into the water pressure maintaining assembly II 36 along with the water flow. The water flow containing dregs enters the return pipe I 32 after flowing through the return pipe II 35, and then enters the sewage pipe 31 after flowing through the return pipe I 32, and is centrally returned to the water source through the sewage pipe 31.

[0057] As Figure 4 shown, the water pressure maintaining assembly I 34 includes:

[0058] A conical tube 341, the bottom end of which is connected to the U-shaped tube 33, the top end of which is integrally provided with a connecting tube 342, and the connecting tube 342 is connected to the reflux tube I 32;

[0059] A spiral baffle I 343 , wherein the spiral baffle I 343 is connected in the connecting pipe 342 , and the spiral baffle I 343 is used to block the water flow passing through the connecting pipe 342 .

[0060] It can be understood that after the water flow and residue in the branch pipe 22 flow to the end of the branch pipe 22, they flow into the U-shaped tube 33, and then enter the tapered tube 341 after flowing through the U-shaped tube 33. The amount of water flow at the end of the branch pipe 22 is reduced by the tapered tube 341, and the water flow and residue are guided into the connecting pipe 342. The spiral baffle Ⅰ343 is set in the connecting pipe 342 to block the water flow, slow down the speed of the water flow, and ensure that the residue can pass smoothly through the connecting pipe 342. The water flow and residue flow through the connecting pipe 342 and then enter the return pipe Ⅰ32, thereby ensuring that the water pressure in the branch pipe 22 can be maintained at the required value, so that the water flow in the branch pipe 22 can smoothly enter the spiral drip irrigation pipe 23.

[0061] like Figure 5 As shown, the sewage pipe 31 is connected to a self-operated pressure regulating valve 37 , and the self-operated pressure regulating valve 37 is used to automatically adjust the pressure in the drip irrigation pipe network 2 .

[0062] It is understandable that if the flow rate of the sewage pipe 31 is too large, the pressure in the drip irrigation network 2 will be reduced, and the water in the drip irrigation network 2 cannot flow out to drip irrigate the roots of the oil tea trees. If the flow rate of the sewage pipe 31 is too small, the pressure in the drip irrigation network 2 will increase, which may easily cause the branch pipe 22 or the spiral drip irrigation pipe 23 to rupture under pressure. Therefore, a self-operated pressure regulating valve 37 is connected to the sewage pipe 31. The self-operated pressure regulating valve 37 automatically adjusts the flow rate of the sewage pipe 31 according to the pressure in the drip irrigation network 2. When the pressure in the drip irrigation network 2 increases, the opening of the self-operated pressure regulating valve 37 increases. When the pressure in the drip irrigation network 2 decreases, the opening of the self-operated pressure regulating valve 37 decreases, so as to automatically adjust the pressure in the drip irrigation network 2 to avoid excessive or insufficient pressure in the drip irrigation network 2.

[0063] like Figure 6 As shown, the header hub 1 includes:

[0064] A water inlet pipe 11, the head end of which is used to extend into a water source, and the head end of which is connected to a spherical screen 12, and the spherical screen 12 is used to prevent larger residues in the water source from entering the water inlet pipe 11;

[0065] A water pump 13, the water pump 13 is driven by a variable-frequency motor, and the input end of the water pump 13 is communicated with the water inlet pipe 11;

[0066] A water delivery pipe 14, one end of the water delivery pipe 14 is communicated with the output end of the water pump 13, and the other end of the water delivery pipe 14 is communicated with the main pipe 21.

[0067] It can be understood that when drip irrigation is carried out on the camellia oleifera tree, the variable-frequency motor is started to drive the water pump 13. The input end of the water pump 13 extends into the water source through the water inlet pipe 11 for extraction, and the large debris in the water source is blocked from entering the water inlet pipe 11 through the spherical screen 12 connected to the head end of the water inlet pipe 11, so as to avoid blockage caused by large debris. The extracted water is then transported into the water delivery pipe 14 by the output end of the water pump 13, and the water flows through the water delivery pipe 14 and then enters the main pipe 21, so as to realize the extraction and transportation of the water source; and by adjusting and increasing the speed of the variable-frequency motor, the transportation speed of the water pump 13 can be increased, so as to accelerate the water flow speed of the main pipe 21, the branch pipe 22 and the spiral drip irrigation pipe 23. The internal parts of the main pipe 21, the branch pipe 22 and the spiral drip irrigation pipe 23 are flushed by the accelerated water flow to ensure the drip irrigation effect on the roots of the camellia oleifera tree.

[0068] As Figure 7 - Figure 8 shown, a plurality of flow-limiting cylinders 4 are also fixedly connected in the main pipe 21. The flow-limiting cylinders 4 are located behind the connection between the branch pipe 22 and the main pipe 21. The inner wall of the head of the flow-limiting cylinder 4 is set as a funnel-shaped inner wall 41, and a spiral baffle II 42 is integrally arranged on the inner wall of the flow-limiting cylinder 4. The spiral baffle II 42 is used to apply resistance to the water flow passing through the flow-limiting cylinder 4, so that the pressure difference in the plurality of branch pipes 22 is reduced.

[0069] It can be understood that when water is transported by the water pump 13 into the main pipe 21 and then flows into multiple branch pipes 22, there is a pressure difference in the water flow in the multiple branch pipes 22, resulting in an increased drip irrigation amount for the oil tea trees in some planting areas and a decreased drip irrigation amount for the oil tea trees in some planting areas, making the water supply to the oil tea trees in multiple planting areas uneven. Therefore, a plurality of flow limiting cylinders 4 are fixedly connected in the main pipe 21. The flow limiting cylinders 4 are located behind the connection between the branch pipes 22 and the main pipe 21. When water is transported by the water pump 13 into the main pipe 21 and passes through the connection between the branch pipe 22 and the main pipe 21, the amount of water flowing towards the end of the main pipe 21 is reduced through the flow limiting cylinder 4, and the flowing water is blocked by the spiral baffle II 42 integrally arranged on the inner wall of the flow limiting cylinder 4, slowing down the flow rate of the flowing water, so that the water in the main pipe 21 preferentially enters the branch pipes 22. When the water flow in the branch pipe 22 near the head end of the main pipe 21 and the multiple spiral drip irrigation pipes 23 connected to the branch pipe 22 is saturated, the water pressure in the main pipe 21 increases, and the water flow accelerates through the flow limiting cylinder 4 and then preferentially enters the next branch pipe 22. The water pressure in the main pipe 21 gradually decreases as the water flows in the multiple branch pipes 22 and the spiral drip irrigation pipes 23 become saturated. Until the water flows in the multiple branch pipes 22 and the multiple spiral drip irrigation pipes 23 are all saturated, the water pressure in the main pipe 21 tends to be stable. By setting the inner wall of the head part of the flow limiting cylinder 4 as a funnel-shaped inner wall 41, the water pressure borne by the flow limiting cylinder 4 is slowed down, thereby reducing the pressure difference in the multiple branch pipes 22 and ensuring the uniformity of the water supply to the oil tea trees in multiple planting areas.

[0070] It should be noted that the inner diameter of the flow limiting cylinder 4 is larger than the inner diameter of the return pipe I 32, and the inner diameter of the return pipe I 32 is larger than the inner diameter of the return pipe II 35, so as to ensure that the water flow in the main pipe 21 can stably enter the multiple branch pipes 22 and the multiple spiral drip irrigation pipes 23.

[0071] As Figure 9 shown, a plurality of guide cylinders I 5 are fixedly connected in the branch pipe 22. Through holes I 51 are formed in the peripheral wall of the guide cylinder I 5. The through holes I 51 are communicated with the spiral drip irrigation pipes 23. A guide ring plate 52 is integrally arranged at the tail end of the guide cylinder I 5. A blocking cylinder 53 is integrally arranged on the guide ring plate 52. The blocking cylinder 53 is located in the guide cylinder I 5. A conical screen I 54 is connected between the head end of the blocking cylinder 53 and the head end of the guide cylinder I 5. The conical screen I 54 is used to filter the dregs in the water flow in the branch pipe 22 to prevent the dregs in the water flow from entering the spiral drip irrigation pipes 23.

[0072] It can be understood that after the water flow is transported from the branch pipe 22 into the multiple spiral drip irrigation pipes 23, the water flow rate and water flow pressure entering the multiple spiral drip irrigation pipes 23 are uneven, resulting in uneven water supply to each oil tea tree; therefore, multiple guide tubes Ⅰ5 are fixedly connected in the branch pipe 22, and when the water flow in the branch pipe 22 passes through the guide tube Ⅰ5, the water flow is divided by the cooperation of the guide ring plate 52 and the barrier tube 53, so that a part of the water flow enters the gap between the barrier tube 53 and the guide tube Ⅰ5, and enters the barrier tube 53. The water flow between the tube 53 and the guide tube Ⅰ5 enters the spiral drip irrigation pipe 23 through the through hole Ⅰ51 for drip irrigation, and is blocked by the conical screen Ⅰ54 to prevent the residue from entering the spiral drip irrigation pipe 23. Another part of the water flow and the residue pass through the barrier tube 53 and flow to the end of the branch pipe 22. After gradually passing through multiple guide tubes Ⅰ5, the water flow and the residue enter the sewage discharge mechanism 3 and flow back to the water source, so that the water flow rate and water pressure entering the multiple spiral drip irrigation pipes 23 are unified, ensuring the uniformity of the water supply to each oil tea tree.

[0073] like Figure 10 As shown, a plurality of connecting tubes 6 are fixedly connected in the spiral drip irrigation pipe 23, a through hole II 61 is opened on the peripheral wall of the connecting tube 6, and the through hole II 61 is connected to the drip irrigation hole, a guide tube II 62 is arranged in the connecting tube 6, a spiral baffle III 63 is integrally arranged on the outer wall of the guide tube II 62, and the spiral baffle III 63 is fixedly connected to the inner wall of the connecting tube 6, a conical screen II 64 is connected between the head end of the guide tube II 62 and the head end of the connecting tube 6, and the conical screen II 64 is used to filter the fine residue in the water flow in the spiral drip irrigation pipe 23.

[0074] It can be understood that when the water in the spiral drip irrigation pipe 23 flows through the flow connection tube 6, the water flow is divided by the guide tube II 62, so that a part of the water flow enters between the connection tube 6 and the guide tube II 62, and the water flow between the connection tube 6 and the guide tube II 62 is blocked by the spiral baffle III 63 to reduce the water flow speed, so that the water flow between the connection tube 6 and the guide tube II 62 flows through the flow hole II 61 and then seeps out from the drip irrigation hole to drip irrigate the root system of the oil tea tree, and through the conical screen II 6 4 prevents the fine residues in the water flow from entering between the connecting tube 6 and the guide tube II 62, and the other part of the water flow and the fine residues flow from the guide tube II 62 through the end of the backward spiral drip irrigation pipe 23. The water flow and the fine residues gradually flow through multiple connecting tubes 6, and then flow through the water pressure maintaining component II 36, the return pipe II 35, and the return pipe I 32 in turn and enter the sewage pipe 31, and then flow back to the water source from the sewage pipe 31, so as to ensure the drip irrigation amount of each drip irrigation hole and the drip irrigation effect on the root system of the oil tea tree.

[0075] like Figure 5As shown in the figure, it further includes a bracket 7, which is used to be erected in the water source. A sieve basket 71 is fixedly connected to the bracket 7. A cover plate 72 is arranged at the top of the sieve basket 71. The output end of the sewage discharge pipe 31 is communicated and arranged inside the sieve basket 71. The sieve basket 71 is used to collect the residues in the water flow discharged by the sewage discharge pipe 31.

[0076] It can be understood that by erecting the sieve basket 71 through the bracket 7, the sieve basket 71 is fixed in the water source. The water flow and residues discharged by the sewage discharge pipe 31 enter the sieve basket 71. The residues are screened and collected through the sieve basket 71, preventing the residues from flowing back into the water source and then entering the drip irrigation pipe network 2 again. The top of the sieve basket 71 is closed by the cover plate 72 to prevent the residues from entering the water source from the top of the sieve basket 71. When cleaning the residues in the sieve basket 71, the cover plate 72 is removed and then the residues in the sieve basket 71 are removed, realizing the collection and treatment of the residues discharged by the sewage discharge pipe 31 and being beneficial to the purification of the water source.
