Description

Technical Field

[0001] This invention relates to the field of agricultural technology, and in particular to an integrated device for drip irrigation and foliar fertilization of crops. Background Technology

[0002] Drip irrigation and foliar fertilization are two important technologies for cultivating crops. The former saves water resources, ensuring the water needs of crops while reducing unnecessary waste; the latter, as a highly efficient fertilization technology, supplements soil fertility, allowing crops to quickly absorb nutrients. However, existing drip irrigation and foliar fertilization equipment are often independent, resulting in large space requirements and inconvenience when used simultaneously. Furthermore, existing drip irrigation and foliar fertilization equipment suffers from poor synchronization; the action time of multiple drip irrigation or foliar fertilization locations is often limited by the linear flow of fluid, leading to time differences, especially when the pipeline is long. This results in significant differences in the volume of water or fertilizer discharged during operation, hindering precise control. In addition, existing drip irrigation or foliar fertilization equipment often struggles to quickly and efficiently match and repair the locations of drip irrigation and spray nozzles according to the actual environment, resulting in insufficient adaptability and repeatability. These shortcomings highlight the deficiencies of existing technologies. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated device for drip irrigation and foliar fertilization of crops to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An integrated drip irrigation and foliar fertilization device for crops includes a main water tank, a secondary water tank, a first pipe, a second pipe, a drip irrigation network, a first valve, a connecting pipe, and a lifting mechanism. The upper parts of the main water tank and the secondary water tank are respectively penetrating and vertically arranged. The main water tank and the secondary water tank are made of transparent or semi-transparent material or have vertical and transparent observation windows that allow observation of the water volume inside. The bottom of the main water tank and the bottom of the secondary water tank are respectively fixedly connected to the first pipe and the second pipe. The two first pipes are respectively connected to two opposite ends of the drip irrigation network and are respectively equipped with a first valve to control the on / off state. The two second pipes are connected together by a transparent connecting pipe. The bottom of the main water tank and the bottom of the secondary water tank are respectively equipped with a controllable lifting mechanism.

[0006] Based on the above technical solution, a No. 3 pipe is fixedly connected to the middle of the side wall of the main water tank, the No. 1 valve is driven and controlled by electricity, the controller is connected to an external power source, the two No. 1 valves are electrically connected to the controller, and the No. 3 pipe is equipped with a No. 2 valve for controlling the on and off, and is connected to the external water supply system.

[0007] Based on the above technical solution, the second valve is a float valve, which is installed at the end of the third pipe that extends into the main water tank. The float valve is located inside the main water tank and is used to control the amount of water in the main water tank. The other end of the third pipe is connected to the external water supply system.

[0008] Based on the above technical solution, the drip irrigation network includes a No. 1 main pipe, a No. 1 secondary pipe, drip irrigation holes, and a No. 1 one-way valve. The two No. 1 main pipes are arranged side by side and are respectively connected to the No. 1 pipe. Multiple No. 1 secondary pipes are connected side by side between the two No. 1 main pipes. Each No. 1 secondary pipe is provided with multiple drip irrigation holes. A No. 1 one-way valve is detachably installed between the No. 1 main pipe and the No. 1 secondary pipe. Each No. 1 one-way valve only allows fluid with a certain pressure to flow from the No. 1 main pipe to the No. 1 secondary pipe.

[0009] Based on the above technical solution, the main water tank and the auxiliary water tank are respectively equipped with controllable lifting support mechanisms. Each of the two support mechanisms is equipped with a water tank. The two support mechanisms are used to control the up and down movement of the water tanks. The water tanks are closed. The bottom of each of the two water tanks is fixedly connected to a drain pipe. The drain pipe portion located outside the water tank is arranged vertically upwards. Each of the two water tanks is fixed with a water pump. The drain pipes of the two water pumps are respectively connected to the inner cavity of the two water tanks. The position where the drain pipes of the water pumps are connected to the inner cavity of the water tank is located at the bottom of the inner cavity of the water tank. The suction pipes of the two water pumps are respectively sealed and pass through the water tanks and extend to the outside. The two water pumps are respectively electrically connected to the controller. The two drain pipes are respectively connected to two mutually distant ends of the foliar fertilization pipeline network.

[0010] Based on the above technical solution, the suction pipes of the two water pumps are respectively equipped with flexible extension pipes. The two extension pipes extend to the bottom of the inner cavity of the main water tank and the auxiliary water tank respectively, with some excess. The foliar fertilization pipeline network includes a second main pipe, a second auxiliary pipe, spray holes, and a second check valve. The two second main pipes are arranged side by side, and multiple second auxiliary pipes are connected side by side between the two second main pipes. Each second auxiliary pipe is provided with multiple sets of spray holes. Each set of spray holes consists of multiple spray holes that converge with each other. A second check valve is detachably installed between the second main pipe and the second auxiliary pipe. Each second check valve only allows fluid with a certain pressure to flow from the second main pipe to the second auxiliary pipe.

[0011] Based on the above technical solution, the drip irrigation hole and the spray hole are formed by their respective hole-making mechanisms. The hole-making mechanism includes a fastening seat, a support plate, a compression spring, a cover plate, a main needle, and a secondary needle. The upper part of the fastening seat is through-hole and flared, while the middle and lower parts are cylindrical with a superior arc. The bottom of the fastening seat is radially slidably connected to the support plate. A compression spring is fixed between the support plate and the fastening seat. Under the elastic repulsive force of the compression spring, the support plate tends to move downwards. The upper part is hinged with a cover plate at the front and back. The cover plate can seal and unseal the flared part at the top of the fastening seat. The cover plate and the fastening seat are interlocked with the outer wall of the first or second auxiliary pipe. The top of the support plate of the hole-making mechanism for processing drip irrigation holes is radially fixed with a vertical main needle. The top of the support plate of the hole-making mechanism for processing spray holes is radially fixed with multiple vertical secondary needles. The diameter of the secondary needles is smaller than that of the main needles. The first and second auxiliary pipes are made of PVC or PE material.

[0012] Based on the above technical solution, the drip irrigation hole and spray hole can be sealed using a sealing component. The sealing component includes a sealing cover, a protrusion, and an elastic band. The upper part of the sealing cover extends through and forms a flared protrusion, while the middle and lower parts are cylindrical with a superior arc. The two flared protrusions on the upper part of the sealing cover are fitted with an elastic band. The sealing cover is tightly fitted and inserted into the first and second auxiliary pipes.

[0013] Based on the above technical solution, the lifting mechanism includes a support ring, a support screw, a support cylinder, and a base plate. The main water tank and the auxiliary water tank are respectively fixed with support rings. Multiple vertical support screws are fixed to the two support rings respectively. Each support screw is threadedly connected to a vertical support cylinder. A horizontal base plate is fixed to the bottom end of each support cylinder.

[0014] Based on the above technical solution, the support mechanism includes a lead screw, a nut, and a support beam. Two sets of lead screws are fixed inside the main water tank and the auxiliary water tank, respectively. Each set of lead screws includes two lead screws that are far apart and parallel to each other. The two sets of lead screws inside the main water tank and the auxiliary water tank are arranged in parallel. Each lead screw is coaxially threaded with a nut. Each set of lead screws is connected to a support beam with a gap between its upper and lower ends. The bottom end of the support beam touches the top end of the nut. The water tank is placed on the top of the support beam and is connected to the main water tank or the auxiliary water tank with a gap between its upper and lower ends. The density of the water tank is greater than that of water. The lead screw, nut, and support beam are made of corrosion-resistant materials to carry the water tank and the water inside it.

[0015] Compared with the prior art, the present invention has the following advantages: When the present invention is used, the water depth in the main water tank and the auxiliary water tank can be made to be consistent through the action of the connecting pipe and the lifting mechanism. Then, with the help of the water pump and the support mechanism, the water volume in the two water tanks can be made to be consistent. Thus, in conjunction with the drip irrigation network and the foliar fertilization network, the time difference between water and fertilizer reaching the drip irrigation holes and spray holes can be shortened, thereby reducing the difference in water volume between drip irrigation and the difference in water and fertilizer volume between foliar fertilization, thereby achieving fine control.

[0016] Through the hole-making mechanism and sealing components, drip irrigation holes and spray holes can be efficiently and quickly processed on the No. 1 and No. 2 auxiliary pipes according to the actual conditions, and the processed drip irrigation holes and spray holes can be quickly and efficiently sealed, thereby improving practicality and reusability.

[0017] By utilizing the gaps between the water tank and the main and auxiliary water tanks, as well as the use of extension pipes, the space occupied by the water tank, main and auxiliary water tanks can be partially integrated, reducing space usage and making it convenient to use.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-7 As shown, an integrated drip irrigation and foliar fertilization device for crops includes a main water tank 1, a secondary water tank 2, a first pipe 3, a second pipe 4, a drip irrigation network 5, a first valve 6, a connecting pipe 7, and a lifting mechanism 8. The upper parts of the main water tank 1 and the secondary water tank 2 are respectively penetrating and vertically arranged. The main water tank 1 and the secondary water tank 2 are made of transparent or semi-transparent material or have vertical and transparent observation windows that allow observation of the water volume inside. The bottom of the main water tank 1 and the bottom of the secondary water tank 2 are respectively fixedly connected to the first pipe 3 and the second pipe 4. The two first pipes 3 are respectively connected to two distant ends of the drip irrigation network 5 and are respectively equipped with a first valve 6 to control the on / off state. The two second pipes 4 are connected together by a transparent connecting pipe 7. The bottom of the main water tank 1 and the bottom of the secondary water tank 2 are respectively equipped with a controllable lifting mechanism 8.

[0028] During use, water is poured into the main water tank 1. Due to the connecting pipe 7, the water in the main water tank 1 and the auxiliary water tank 2 can flow to each other until they are at the same level. The height of the main water tank 1 and the auxiliary water tank 2 from the ground is adjusted by the lifting mechanism 8 until the distance between the two No. 1 pipes 3 and the water surface in their respective main water tanks 1 and auxiliary water tanks 2 is approximately the same. At this time, the water pressure at the connection points of the two No. 1 pipes 3 and the main water tanks 1 and auxiliary water tanks 2 is approximately the same. When drip irrigation is needed, the two No. 1 valves 6 are opened at the same time. The water in the main water tank 1 and the auxiliary water tank 2 flows into the drip irrigation network 5 through the No. 1 pipes 3, thereby shortening the time to cover each drip irrigation operation area and reducing the time difference of water linear flow to each drip irrigation operation area. This reduces the difference in drainage volume during drip irrigation and is conducive to fine control.

[0029] The main water tank 1 has a fixed connection to the middle of the side wall of the No. 3 pipe 9. The No. 1 valve 6 is driven and controlled by electricity. The controller is connected to an external power source and is a known existing technology, such as a microcontroller. The two No. 1 valves 6 are electrically connected to the controller. The No. 3 pipe 9 is equipped with a No. 2 valve 11 for controlling the on and off of the water supply and is connected to the external water supply system.

[0030] Furthermore, the controller is used to control the simultaneous opening and closing of two valves 6 (number 1) for precise control. Water is injected into the main water tank 1 through pipe 9 (number 3), and valve 11 (number 2) is used to control the timing of water injection.

[0031] The second valve 11 is a float valve and is installed at the end of the third pipe 9 that extends into the main water tank 1. The float valve is located in the main water tank 1 and is used to control the amount of water in the main water tank 1. The other end of the third pipe 9 is connected to the external water supply system.

[0032] By setting a float valve, the water supply system can automatically replenish the water in the main water tank 1 using tap water, thereby ensuring that the water pressure tends to be stable, which in turn ensures that the drip irrigation operation effect tends to be stable.

[0033] The drip irrigation network 5 includes a main pipe 13, a secondary pipe 14, drip irrigation holes 15, and a one-way valve 16. Two main pipes 13 are arranged side by side and are respectively connected to a pipe 3. Multiple secondary pipes 14 are connected side by side between the two main pipes 13. Each secondary pipe 14 is provided with multiple drip irrigation holes 15. A one-way valve 16 is detachably installed between the main pipe 13 and the secondary pipe 14. Each one-way valve 16 only allows fluid with a certain pressure to flow from the main pipe 13 to the secondary pipe 14.

[0034] Furthermore, when valve 6 is opened, the water in the main water tank 1 and the auxiliary water tank 2 flow into and fill the two main pipes 13. When the water volume in the main water tank 1 and the auxiliary water tank 2 reaches a certain level, the water pressure on the check valve 16 reaches the conduction value. At this time, each check valve 16 is open, allowing water to enter both ends of each auxiliary pipe 14 simultaneously, and then be discharged through the drip irrigation hole 15. This reduces the time difference when water is discharged from each drip irrigation hole 15, further shortening the volume difference of water discharged during drip irrigation and improving the precision of fine control. When the water volume in the main water tank 1 and the auxiliary water tank 2 decreases to a certain level, the water pressure is insufficient, and the check valve 16 closes. The drip irrigation operation stops after the water in the auxiliary pipe 14 is drained.

[0035] The main water tank 1 and the auxiliary water tank 2 are each equipped with a controllable lifting support mechanism 17. Each of the two support mechanisms 17 is equipped with a water tank 18. The two support mechanisms 17 are used to control the up and down movement of the water tank 18. The water tank 18 is closed. The bottom of each of the two water tanks 18 is fixedly connected to a drain pipe 19. The drain pipe 19 located outside the water tank 18 is arranged vertically upwards. Each of the two water tanks 18 is fixed with a water pump 20. The drain pipes of the two water pumps 20 are respectively connected to the inner cavity of the two water tanks 18. The position where the drain pipe of the water pump 20 is connected to the inner cavity of the water tank 18 is located at the bottom of the inner cavity of the water tank 18. The suction pipes of the two water pumps 20 are respectively sealed and pass through the water tank 18 and extend to the outside. The two water pumps 20 are respectively electrically connected to a controller. The two drain pipes 19 are respectively connected to two mutually distant ends of the foliar fertilizer network 21.

[0036] Furthermore, by controlling the support mechanism 17 to adjust the height of the water tank 18 relative to the main water tank 1 and the auxiliary water tank 2, the height of the two water tanks 18 is kept consistent. Initially, the air pressure inside the water tank 18 is the same as the external atmospheric pressure. By controlling the two water pumps 20 to draw water and fertilizer from the outside, it can be injected into the water tank 18. As the volume of water and fertilizer in the water tank 18 increases, it will compress the air inside, and the air pressure and water pressure will work together on the drain pipe 19. When the pressure reaches a certain value, it can be discharged upward through the drain pipe 19 into the foliar fertilization network 21 for foliar fertilization. Through this method of combined air pressure and water pressure, the timing of water intake at both ends of the foliar fertilization network 21 can be roughly made closer to the same, thereby shortening the time to cover various foliar fertilization operation areas, and reducing the time difference of linear flow of water and fertilizer to various foliar fertilization operation areas, thereby reducing the difference in drainage volume during foliar fertilization, which is conducive to fine control.

[0037] The suction pipes of the two water pumps 20 are respectively equipped with flexible extension pipes 22. The two extension pipes 22 extend to the bottom of the inner cavity of the main water tank 1 and the auxiliary water tank 2 respectively, with some excess. The foliar fertilization pipeline network 21 includes a second main pipe 23, a second auxiliary pipe 24, spray holes 25, and a second one-way valve 26. The two second main pipes 23 are arranged side by side, and multiple second auxiliary pipes 24 are connected side by side between the two second main pipes 23. Each second auxiliary pipe 24 is provided with multiple sets of spray holes 25. Each set of spray holes 25 is composed of multiple spray holes 25 that are clustered together. A second one-way valve 26 is detachably installed between the second main pipe 23 and the second auxiliary pipe 24. Each second one-way valve 26 only allows fluid with a certain pressure to flow from the second main pipe 23 to the second auxiliary pipe 24.

[0038] Furthermore, by setting up extension pipes 22, water and fertilizer can be directly drawn from the main water tank 1 and the auxiliary water tank 2. Water and fertilizer in the main water tank 1 and the auxiliary water tank 2 can be manually injected. At this time, under the action of connecting pipe 7, the water pressure at the two extension pipes 22 is consistent. Therefore, the volume of water and fertilizer entering the water tank 18 after being drawn by the two water pumps 20 at the same time is also close to the same. This helps to ensure that the pressure acting on both ends of the foliar fertilization pipeline network 21 is close to the same, thereby reducing the difference in drainage volume during foliar fertilization and facilitating precise control.

[0039] The drip irrigation hole 15 and the spray hole 25 are formed by their respective hole-making mechanisms 27. The hole-making mechanism 27 includes a fastening seat 28, a support plate 29, a compression spring 30, a cover plate 31, a main needle 32, and a secondary needle 33. The upper part of the fastening seat 28 is through-hole and flared, while the middle and lower parts are cylindrical with a superior arc. The support plate 29 is radially slidably connected to the bottom of the fastening seat 28. The support plate 29 and the fastening seat 28 are fixed together by a compression spring 30. The support plate 29 has a downward tendency under the elastic repulsive force of the compression spring 30. The upper part of the fastening seat 28 is hinged front and back. A cover plate 31 is attached, which can seal and unseal the upper flared part of the fastening seat 28. The cover plate 31 and the fastening seat 28 are intermittently inserted into the outer wall of the first auxiliary pipe 14 or the outer wall of the second auxiliary pipe 24. The top of the support plate 29 of the hole-making mechanism 27 for processing the drip irrigation hole 15 is radially fixed with a vertical main needle 32. The top of the support plate 29 of the hole-making mechanism 27 for processing the spray hole 25 is radially fixed with multiple vertical auxiliary needles 33. The diameter of the auxiliary needles 33 is smaller than that of the main needles 32. The first auxiliary pipe 14 and the second auxiliary pipe 24 are made of PVC or PE material.

[0040] Furthermore, the flared structure of the fastening seat 28 allows for arbitrary fastening at various points on the first and second auxiliary tubes 14 and 24. The fastening seat 28 can also rotate freely. Then, the cover plate 31 is flipped over, sealing the upper penetration of the fastening seat 28. Holding the fastening seat 28 and cover plate 31, and pulling the support plate 29 with four fingers overcomes the elastic repulsive force of the compression spring 30, causing the main needle 32 and auxiliary needle 33 to move closer to the first and second auxiliary tubes 14 and 24, thus targeting the first... Puncture the corresponding parts of the secondary tube 14 and the second secondary tube 24, and then release. Under the elastic repulsive force of the compression spring 30, the main needle 32 and the secondary needle 33 will return to their original positions. Then, according to the actual situation, drip irrigation holes 15 and spray holes 25 can be processed at fixed intervals to improve practicality, facilitate operation, and increase work efficiency. After the drip irrigation holes 15 or spray holes 25 on the same first secondary tube 14 or second secondary tube 24 are processed, flip the cover plate 31 in the opposite direction, and then use the through part of the fastening seat 28 to remove the fastening seat 28.

[0041] The drip irrigation hole 15 and the spray hole 25 can be sealed using a sealing member 34. The sealing member 34 includes a sealing cover 35, a protrusion 36, and an elastic band 37. The upper part of the sealing cover 35 extends through and forms a flared protrusion 36, while the middle and lower parts are cylindrical with an arc shape. The two flared protrusions 36 on the upper part of the sealing cover 35 are fitted together with the elastic band 37. The sealing cover 35 is tightly fitted and inserted into the first auxiliary pipe 14 and the second auxiliary pipe 24.

[0042] Furthermore, the sealing cover 35 can be fastened to any part of the first auxiliary pipe 14 or the second auxiliary pipe 24 through the protrusion 36 of the sealing cover 35, and then the elastic rubber band 37 can be attached to improve the fit between the sealing cover 35 and the first auxiliary pipe 14 or the second auxiliary pipe 24, thereby improving the sealing effect on the drip irrigation hole 15 and the spray hole 25, improving reusability, and making it convenient and efficient. If necessary, sealant can also be applied to the mating surface of the sealing cover 35 and the first auxiliary pipe 14 or the second auxiliary pipe 24 in advance.

[0043] The lifting mechanism 8 includes a support ring 38, a support screw 39, a support screw cylinder 40, and a base plate 41. The main water tank 1 and the auxiliary water tank 2 are respectively fixed with support rings 38. Multiple vertical support screws 39 are fixed to the two support rings 38 respectively. Each support screw 39 is threadedly connected to a vertical support screw cylinder 40. A horizontal base plate 41 is fixed to the bottom end of each support screw cylinder 40.

[0044] Furthermore, by manually rotating the support screw cylinder 40, the vertical height of the support screw cylinder 40 relative to the support screw 39 can be adjusted. Then, by using the base plate 41 to support the ground, the height of the main water tank 1 and the auxiliary water tank 2 relative to the ground can be adjusted.

[0045] The support mechanism 17 includes a lead screw 42, a nut 43, and a support beam 44. Two sets of lead screws 42 are fixed inside the main water tank 1 and the auxiliary water tank 2, respectively. Each set of lead screws 42 includes two lead screws 42 that are far apart from each other. The two sets of lead screws 42 in the main water tank 1 and the auxiliary water tank 2 are arranged side by side. Each lead screw 42 is coaxially threaded with a nut 43. Each set of lead screws 42 is connected to the support beam 44 with a gap between its upper and lower ends. The bottom end of the support beam 44 touches the top end of the nut 43. The water tank 18 is placed on the top end of the support beam 44 and is connected to the main water tank 1 or the auxiliary water tank 2 with a gap between its upper and lower ends. The density of the water tank 18 is greater than that of water. The lead screw 42, nut 43, and support beam 44 are made of corrosion-resistant materials to carry the water tank 18 and the water inside it.

[0046] Furthermore, before placing the water tank 18 and the support beam 44, the nuts 43 are manually rotated to ensure that the height of each nut 43 is consistent. Then, the support beam 44 is placed, which can support the water tank 18 and adjust the height of the water tank 18. The gap connection between the water tank 18 and the main water tank 1 and the auxiliary water tank 2, as well as the use of the extension pipe 22, allow the space occupied by the water tank 18, the main water tank 1, and the auxiliary water tank 2 to be partially integrated, reducing space occupation, making it convenient to use, and forming an integrated drip irrigation and foliar fertilization function.

[0047] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
