Description

[0002] The oil tea tree is one of the four major woody oil crops in the world. It grows in the mountains and hilly areas of the subtropical region in southern China. It is a pure natural high-grade oil crop unique to China.

[0003] In order to ensure that there is enough water for the cultivation of tea oil trees, a drip irrigation system is used to supply water to tea oil trees; however, the existing drip irrigation system has strict requirements on the water quality of the water source, which should generally be filtered and, if necessary, precipitated and chemically treated. The areas where tea oil trees are planted are mostly mountainous and hilly areas, and it is inconvenient to transport water for drip irrigation, so drip irrigation can only be carried out by finding a nearby water source; and the water sources in mountainous and hilly areas are mostly stored water, which contains a large amount of scum. Filtering and / or precipitating and chemically treating the stored water will undoubtedly increase the planting cost and reduce the planting income; however, the scum in the stored water can easily cause the network pipe of the existing drip irrigation system to be blocked, and in severe cases, the entire drip irrigation system will not work properly or even be scrapped; resulting in little benefit from the use of a drip irrigation system to supply water to tea oil trees, and thus the need to use a water source containing scum for drip irrigation.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present invention, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0021] like Figure 1-Figure 2 As shown, this embodiment provides a tea tree drip irrigation system, including: A head hub 1, the head hub 1 is used to connect to a water source for transportation; A drip irrigation pipe network 2, the drip irrigation pipe network 2 includes a main pipe 21, the main pipe 21 is connected to the output end of the head hub 1, the main pipe 21 is connected to a plurality of branch pipes 22, the branch pipes 22 are connected to a plurality of spiral drip irrigation pipes 23, the diameter of the spiral drip irrigation pipes 23 is smaller than the diameter of the branch pipes 22, the spiral drip irrigation pipes 23 are symmetrically provided with a plurality of drip irrigation holes, and the spiral drip irrigation pipes 23 are used for drip irrigation of the root system of the oil tea tree; The sewage discharge mechanism 3 has an input end connected to the end of the branch pipe 22, and an output end connected to a water source. The sewage discharge mechanism 3 is used to return the slag entering the branch pipe 22 to the water source through water flow.

[0022] It can be understood that when drip irrigation is performed on the tea tree, the head hub 1 extracts water from the tea tree planting area and transports the water into the main pipe 21. The main pipe 21 then guides the water to multiple branch pipes 22, and the branch pipes 22 guide the water to multiple spiral drip irrigation pipes 23. The water entering the spiral drip irrigation pipes 23 then seeps out from multiple drip irrigation holes to drip irrigate the root system of the tea tree. After the residue in the water source enters the multiple branch pipes 22 through the main pipe 21, since the diameter of the spiral drip irrigation pipe 23 is smaller than the diameter of the branch pipe 22, the water flow in the branch pipe 22 is greater than the water flow in the spiral drip irrigation pipe 23, making it difficult for the residue in the water flow in the branch pipe 22 to enter the spiral drip irrigation pipe 23. The residue in the branch pipe 22 is pushed into the sewage discharge mechanism 3 by the water flow, and then passes through the sewage discharge mechanism 3 is guided and transported, and the residue is pushed back to the water source through the water flow, so as to avoid the residue being blocked in the drip irrigation network 2; in this technical scheme, the water source in the oil tea tree planting area is extracted through the head hub 1, and transported into the drip irrigation network 2 for drip irrigation of the root system of the oil tea tree, and the diameter of the spiral drip irrigation pipe 23 is set to be smaller than the diameter of the branch pipe 22, so that the residue in the water flow in the branch pipe 22 is difficult to enter the spiral drip irrigation pipe 23, and the residue in the branch pipe 22 is pushed into the sewage discharge mechanism 3 with the water flow, and then guided and transported by the sewage discharge mechanism 3, the residue is pushed back to the water source through the water flow, so as to avoid the residue being blocked in the drip irrigation network 2, and the water source containing the residue is used for drip irrigation, which improves the benefit of the drip irrigation system in supplying water to the oil tea tree.

[0023] It should be noted that the spiral drip irrigation pipe 23 is buried in the ground where the oil tea tree is planted, the middle position of the spiral drip irrigation pipe 23 corresponds to the trunk of the oil tea tree, and the multiple circles of the spiral drip irrigation pipe 23 are extended downward step by step from the inside to the outside; through such a setting, the drip irrigation range of the spiral drip irrigation pipe 23 is extended downward step by step from the inside to the outside, and the hydrotropism of the root system of the oil tea tree makes the root system of the oil tea tree grow downward step by step from the inside to the outside according to the drip irrigation range of the spiral drip irrigation pipe 23, so that the root system of the oil tea tree establishes a stable connection with the soil, avoiding the lodging caused by strong wind climate or the branches of the oil tea tree after fruit hanging.

[0024] like Figure 2 As shown, the sewage discharge mechanism 3 includes: A sewage pipe 31, wherein a plurality of return pipes I32 are connected to the sewage pipe 31, and an output end of the sewage pipe 31 is connected to a water source; A U-shaped tube 33, one end of which is connected to the end of the branch tube 22; A water pressure maintaining component I34, one end of which is connected to the return pipe I32, and the other end of which is connected to the other end of the U-shaped pipe 33. The water pressure maintaining component I34 is used to guide the slag into the return pipe I32 along with the water flow and maintain the water pressure in the branch pipe 22.

[0025] 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 are guided by the U-shaped pipe 33 into the water pressure maintaining component I34, and the flow at the end of the branch pipe 22 is regulated by the water pressure maintaining component I34, 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 residue in the branch pipe 22 is pushed into the water pressure maintaining component I34 with the water flow, and the water containing the residue flows through the return pipe I32 and then enters the sewage pipe 31, and then is concentrated and returned to the water source from the sewage pipe 31.

[0026] like Figure 3 As shown, a plurality of return pipes II35 are connected to the return pipe I32, and the return pipe II35 is connected to one end of a water pressure maintaining component II36, and the other end of the water pressure maintaining component II36 is connected to the end of the spiral drip irrigation pipe 23, and the water pressure maintaining component II36 has the same structure as the water pressure maintaining component I34.

[0027] It can be understood that by setting the diameter of the spiral drip irrigation pipe 23 to be smaller than the diameter of the branch pipe 22, it is difficult for the scum in the water flow in the branch pipe 22 to enter the spiral drip irrigation pipe 23; however, the fine scum will still enter the spiral drip irrigation pipe 23 with the water flow, and the fine scum will accumulate in the spiral drip irrigation pipe 23, which will cause the spiral drip irrigation pipe 23 to be blocked; therefore, a plurality of return pipes II 35 are connected to the return pipe I 32, and the return pipe II 35 is connected to the end of the spiral drip irrigation pipe 23 through the water pressure maintaining component II 36 The water pressure maintaining component II 36 regulates the flow 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 from the multiple drip irrigation holes and enter the fine residue in the spiral drip irrigation pipe 23. The water containing the residue flows into the water pressure maintaining component II 36 after passing through the return pipe II 35, and then enters the return pipe I 32 after passing through the return pipe I 32, and then enters the sewage pipe 31, and is concentratedly returned to the water source by the sewage pipe 31.

[0028] like Figure 4 As shown, the water pressure maintaining assembly Ⅰ34 includes: 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; 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 .

[0029] 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.

[0030] 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 .

[0031] 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.

[0032] like Figure 6 As shown, the header hub 1 includes: 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; A water pump 13, wherein the water pump 13 is driven by a variable frequency motor, and an input end of the water pump 13 is connected to the water inlet pipe 11; A water pipe 14 , one end of which is connected to the output end of the water pump 13 , and the other end of which is connected to the main pipe 21 .

[0033] It can be understood that when drip irrigation is carried out for the oil tea tree, the frequency conversion motor is started to drive the water pump 13, the input end of the water pump 13 is extended into the water source through the water inlet pipe 11 for extraction, and the spherical screen 12 connected to the head end of the water inlet pipe 11 is used to block the larger residues in the water source from entering the water inlet pipe 11, so as to avoid blockage caused by the larger residues, and 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 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 frequency conversion motor, the delivery speed of the water pump 13 can be accelerated, thereby accelerating the water flow speed of the main pipe 21, the branch pipe 22 and the spiral drip irrigation pipe 23, and the inside 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 root system of the oil tea tree.

[0034] like Figure 7-Figure 8 As shown, a plurality of flow limiting cylinders 4 are fixedly connected in the main pipe 21, and the flow limiting cylinders 4 are located behind the connection point 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 also integrally provided on the inner wall of the flow limiting cylinder 4. The spiral baffle II 42 is used to block the water flow passing through the flow limiting cylinder 4, so that the pressure difference in the plurality of branch pipes 22 is reduced.

[0035] It can be understood that when water is transported by the water pump 13 into the main pipe 21 and then flows into the multiple branch pipes 22, there is a pressure difference in the water flow in the multiple branch pipes 22, which leads to an increase in the drip irrigation amount of the oil tea trees in some planting areas and a decrease in the drip irrigation amount of the oil tea trees in some planting areas, resulting in uneven water supply to the oil tea trees in multiple planting areas; therefore, multiple flow limiting cylinders 4 are fixedly connected in the main pipe 21, and the flow limiting cylinder 4 is located behind the connection between the branch pipe 22 and the main pipe 21. When water is transported by the water pump 13 into the main pipe 21 and flows through the connection between the branch pipe 22 and the main pipe 21, the amount of water flowing to the end of the main pipe 21 is reduced by the flow limiting cylinder 4, and the spiral baffle II 42 integrally arranged on the inner wall of the flow limiting cylinder 4 is used to block the water flow passing through, thereby slowing down the flow rate of the water flow passing through, so that the main pipe 21 is The water flow in the pipe 21 preferentially enters the branch pipe 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 flow pressure in the main pipe 21 increases, and the water flow is accelerated through the flow limiting tube 4 and preferentially enters the next branch pipe 22. The water flow pressure in the main pipe 21 decreases step by step as the water flow in the multiple branch pipes 22 and the spiral drip irrigation pipes 23 is saturated. When the water flow in the multiple branch pipes 22 and the multiple spiral drip irrigation pipes 23 is saturated, the water flow pressure in the main pipe 21 tends to be stable. By setting the inner wall of the head of the flow limiting tube 4 to a funnel-shaped inner wall 41, the water flow pressure borne by the flow limiting tube 4 is reduced, 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.

[0036] 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 , thereby ensuring 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 .

[0037] like Fig. 9 As shown, a plurality of guide tubes Ⅰ5 are fixedly connected in the branch pipe 22, a through hole Ⅰ51 is opened on the peripheral wall of the guide tube Ⅰ5, and the through hole Ⅰ51 is connected to the spiral drip irrigation pipe 23. A guide ring plate 52 is integrally provided at the tail end of the guide tube Ⅰ5, and a barrier tube 53 is integrally provided on the guide ring plate 52. The barrier tube 53 is located in the guide tube Ⅰ5, and a conical screen Ⅰ54 is connected between the head end of the barrier tube 53 and the head end of the guide tube Ⅰ5. The conical screen Ⅰ54 is used to filter the residue in the water flow in the branch pipe 22 to prevent the residue in the water flow from entering the spiral drip irrigation pipe 23.

[0038] 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.

[0039] like Fig.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.

[0040] 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.

[0041] like Figure 5 As shown, it also includes a bracket 7, which is used to be erected in a water source. A sieve basket 71 is fixedly connected to the bracket 7, and a cover plate 72 is provided on the top of the sieve basket 71. The output end of the sewage pipe 31 is connected to the sieve basket 71, and the sieve basket 71 is used to collect residues in the water flow discharged from the sewage pipe 31.

[0042] It can be understood that the sieve basket 71 is erected by the bracket 7 so that the sieve basket 71 is fixed in the water source, the water flow and residue discharged from the sewage pipe 31 enter the sieve basket 71, and the residue is screened and collected by the sieve basket 71 to prevent the residue from flowing back to the water source and then entering the drip irrigation network 2 again, and the top of the sieve basket 71 is closed by the cover plate 72 to prevent the residue from entering the water source from the top of the sieve basket 71.
