Description

Technical Field

[0001] This invention relates to the field of drip irrigation technology for fruit tree planting, specifically to an intelligent drip irrigation device integrating water and fertilizer for fruit tree planting and its usage method. Background Technology

[0002] Drip irrigation technology for fruit trees is an efficient and water-saving irrigation method that is widely used in modern orchards, especially in arid or water-scarce areas. By precisely delivering water directly to the roots of fruit trees, the drip irrigation system can improve water use efficiency, reduce water waste, and promote healthy growth and high yields of fruit trees.

[0003] In existing technologies, drip irrigation systems for fruit trees typically consist of a main pipe, branch pipes, and drippers. The main pipe draws water and fertilizer from the source, the branch pipes deliver water and fertilizer to each fruit tree, and the drippers accurately release water and fertilizer into the root zone to complete the drip irrigation. In actual use, although the drip irrigation system is designed to provide uniform water supply, the penetration effect of water varies in different areas of the fruit tree planting area due to differences in soil type, topography, and soil structure. Although the flow rate of the drippers is consistent, in low-lying areas, water cannot penetrate quickly, causing water to accumulate and resulting in high humidity. This can lead to root rot in the fruit trees planted in those areas, affecting the drip irrigation effect. Summary of the Invention

[0015] This invention also provides a method for using an integrated water and fertilizer intelligent drip irrigation device for fruit tree planting, including the following specific steps:

[0016] S1. When using the device, first move the device to the ground where the fruit trees are planted, then adjust the height of the multiple humidity sensors to different heights by adjusting the height adjustment device, so that their detection ends are inserted close to the fruit trees planted in the soil, separate the pressure plate from the water and fertilizer tank, then introduce the water and fertilizer that need to be drip irrigated into the water and fertilizer tank, and then use the pressure plate to close the water and fertilizer tank to complete the installation of the device.

[0017] S2. When in use, the humidity sensor first monitors the humidity of the soil in the fruit trees and transmits the data to the controller. When the soil humidity is low, the controller controls the drive component to move the opening and closing head, so that the conical end of the opening and closing head gradually moves away from the secondary connecting pipe. At this time, the opening and closing head and the secondary connecting pipe are opened, and water and fertilizer are delivered to the drain outlet through the delivery port on the opening and closing head. Water and fertilizer are delivered to the drip irrigation nozzle through the secondary connecting pipe, and water and fertilizer are dripped through the drip irrigation nozzle to complete the drip irrigation of the fruit trees.

[0018] S3. When the drip irrigation causes the soil to reach the predetermined humidity threshold, the controller drives the drive motor to rotate in the opposite direction, resets the opening and closing head, and stops water and fertilizer irrigation, thereby completing the intelligent water and fertilizer irrigation for fruit tree planting.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention monitors the soil moisture of fruit trees using a humidity sensor and transmits the data to a controller. When the soil moisture is low, the controller controls the output of the drive motor to rotate, which in turn drives the secondary screw to rotate. The threaded groove on the surface of the secondary screw drives the drive block to move, which in turn drives the opening and closing head to move. This causes the conical end of the opening and closing head to gradually move away from the secondary connecting pipe, opening the connection between the opening and closing head and the secondary connecting pipe. Water and fertilizer are then delivered through the inlet on the opening and closing head to the outlet, and flow into the outer pipe and the guide hollow plate. The water and fertilizer are then dripped out through the dripper to irrigate the soil in that area. When the drip irrigation causes the soil to reach a predetermined moisture threshold, the controller drives the drive motor to rotate in the opposite direction, resetting the opening and closing head and stopping the water and fertilizer irrigation. This completes the intelligent water and fertilizer irrigation for fruit tree planting, preventing root rot while saving water and fertilizer.

[0021] 2. In this invention, the rotation of the secondary screw simultaneously drives the transmission rod, which in turn drives the primary bevel gear, which in turn drives the secondary bevel gear, which in turn drives the primary screw. The primary screw then moves the rotating tube and the lifting block downwards. The lifting block, through two connecting strips and guided by two grooves, unfolds two filter cotton plates, allowing them to adhere to the upper side of the dripper. This filters impurities in the water and fertilizer, preventing clogging. After irrigation, the drive motor reverses, causing the filter cotton plates to reset and squeeze out excess water and fertilizer. The outer connecting pipe and the hollow guide plate are also emptied to dry their interior, preventing water and fertilizer buildup that could lead to algae and moss growth and clogging of the dripper.

[0022] 3. In this invention, by manually rotating the fixed threaded rod, the fixed threaded rod is disengaged from the positioning ear. Then, by manually rotating the mounting plate, the mounting plate drives two drive rods through two drive ports. The two drive rods drive two sliders away from each other, and the two sliders drive two clamping plates away from each other, thus releasing the external pipe from fixation. Then, the external pipe is removed, achieving the effect of quick disassembly and installation of the external pipe. Attached Figure Description

[0037] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily exceeds the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but still fall within the protection scope of this application.

[0038] Figures 1-11 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-11 The present invention will be further described below.

[0039] like Figures 1-11 As shown, an intelligent drip irrigation device integrating water and fertilizer for fruit tree planting includes a water and fertilizer tank 1. A water inlet is provided on one side of the water and fertilizer tank 1. A main pipe 4 is fixedly installed inside the water inlet. Multiple diversion holes are provided on one side of the main pipe 4. A drip irrigation mechanism is fixedly installed inside the diversion holes. A height adjustment component is fixedly installed on the lower side of the main pipe 4. A humidity sensor 7 is rotatably installed on the main pipe 4 through the height adjustment component.

[0040] The drip irrigation mechanism includes a primary connecting pipe 16, which is fixedly installed in the diversion hole. A limit groove is formed on the inner wall of the primary connecting pipe 16, and a limit block 32 is slidably installed in the limit groove. An opening and closing head 21 is fixedly installed on the lower side of the limit block 32. A control box 5 is fixedly installed on one side of the main pipe 4. An installation hole is formed on one side of the control box 5, and a secondary connecting pipe 22 is fixedly installed in the installation hole. An installation component is fixedly installed on one side of the control box 5, and a drive hole is formed on one side of the control box 5. A drive component is rotatably installed in the drive hole. The drip irrigation nozzle is installed on the control box 5 through the installation component.

[0041] With the above structure, a water inlet is provided on one side of the water and fertilizer tank 1, and the main pipe 4 is connected through the water inlet. When water and fertilizer are poured into the water and fertilizer tank 1, the water and fertilizer will fill the main pipe 4. The main pipe is rectangular and has multiple diversion holes on one side. Each diversion hole opening is equipped with a drip irrigation mechanism. Each drip irrigation mechanism area is located on the lower side of the main pipe and is equipped with a humidity sensor 7 through a height adjustment component. The humidity sensor 7 has the same structure and working principle as the probe-type humidity sensor 7 in the prior art, and will not be described in detail here. The primary connecting pipe 16 and the secondary connecting pipe 22 in the control box 5 are the same size, and an on / off head 21 is slidably installed between them. When the on / off head 21 approaches one end of the primary connecting pipe 16, the water and fertilizer injection is turned on, and vice versa, the water and fertilizer injection is turned off, thereby realizing the opening and closing of the drip irrigation of water and fertilizer.

[0042] Furthermore, the drip nozzle includes an outer pipe 6, which is slidably installed on the surface of the secondary connecting pipe 22. An interface is provided on the surface of the outer pipe 6, and a guide hollow plate 11 is fixedly installed inside the interface. A drain hole is provided on the lower side of the guide hollow plate 11, and a dripper 18 is fixedly installed inside the drain hole.

[0043] With the above structure, the hollow guide plate 11 is hollow inside and is installed on the lower side of the outer pipe 6 in an inverted triangle shape. A drain hole is opened at the bottom of the hollow guide plate 11, and a dripper 18 is installed in the drain hole so that the water and fertilizer entering can drip out.

[0044] Furthermore, the drip nozzle also includes two filter cotton plates 38. The inner wall of the guide hollow plate 11 has two guide grooves 40. The two filter cotton plates 38 are slidably installed in the two guide grooves 40. The inner wall of the guide hollow plate 11 has two extrusion blocks 39 fixedly installed. One side of each of the two filter cotton plates 38 has a movement groove. A connecting strip 41 is slidably installed in the movement groove. One end of the two connecting strips 41 is rotatably installed with the same lifting block 45. A rotating tube 42 is fixedly installed on the upper side of the lifting block 45. A rotating hole is opened on the surface of the outer tube 6. A primary screw 19 is rotatably installed in the rotating hole. The primary screw 19 is screwed to the inner wall of the rotating tube 42.

[0045] With the above structure, the filter cotton plate 38 is composed of a fixed plate and a filter sponge. A limit slider is installed on one side of the fixed plate. The limit slider slides in the guide groove 40 to guide the movement of the filter cotton plate 38. The two guide grooves 40 are symmetrically arranged with the filter cotton plate 38 and are in a "figure-eight" shape. When the lifting block 45 drives the two filter cotton plates 38 to move downward through the two connecting strips 41, the two filter cotton plates 38 slowly unfold and fit against the upper side of the dripper 18 to filter impurities in the water and fertilizer and prevent impurities from clogging the water and fertilizer.

[0046] Furthermore, the drive assembly includes a transmission rod 25, which is rotatably mounted in the drive hole. A secondary screw 30 is coaxially fixedly mounted on one end of the transmission rod 25. A drive block 31 is fixedly mounted on the surface of the opening and closing head 21. The drive block 31 is slidably mounted in the threaded groove on the surface of the secondary screw 30. A drive motor 15 is fixedly mounted on the inner top wall of the control box 5. The output shaft of the drive motor 15 is coaxially fixedly connected to the secondary screw 30.

[0047] With the above structure, the drive motor 15 is a servo motor that can rotate in both directions. The secondary screw 30 has a threaded groove on its surface, and the drive block 31 fits into the threaded groove. When the secondary screw 30 rotates, it will guide the drive block 31 to move horizontally. Its principle is similar to the transmission method of the screw slider. When the secondary screw 30 rotates, it drives the transmission rod 25 to rotate, providing transmission power.

[0048] Furthermore, the drive assembly also includes a primary bevel gear 24, which is fixedly mounted on one end of the transmission rod 25, and a secondary bevel gear 26 is fixedly mounted on the top end of the primary screw 19, with the primary bevel gear 24 meshing with the secondary bevel gear 26.

[0049] With the above structure, the first-stage bevel gear 24 and the second-stage bevel gear 26 drive the first-stage screw 19 to rotate, providing power transmission.

[0050] Furthermore, the mounting components include a mounting plate 23, which is fixedly mounted on one side of the control box 5. A clearance opening is provided on one side of the mounting plate 23, and two limiting openings 29 are provided on one side of the mounting plate 23. A slider 34 is slidably mounted within each limiting opening 29. A clamping plate 33 is fixedly mounted on one side of the slider 34, and a drive rod 35 is fixedly mounted on one side of the slider 34. A mounting plate 14 is rotatably mounted on one side of the mounting plate 23. Two drive ports 20 are provided on one side of the mounting plate 14, and two drive rods 35 are correspondingly slidably mounted within the two drive ports 20. A positioning ear 37 is fixedly mounted on one side of the control box 5, and a screw hole is provided on one side of the positioning ear 37. A fixed threaded rod 36 is screwed into the screw hole. Multiple positioning openings are provided on the side of the mounting plate 14.

[0051] With the above structure, the clearance opening is used to avoid the transmission rod 25. The surface of the mounting plate 14 has two centrally symmetrical drive ports 20. The drive ports 20 facilitate the driving of the drive rod 35, thereby driving the two clamping plates 33 through the two sliders 34. The side of the mounting plate 14 has equally spaced positioning ports. The fixed threaded rod 36 fits into the positioning port, which can limit the mounting plate 14 and prevent it from rotating.

[0052] Furthermore, the height adjustment assembly includes a sleeve 12, which is fixedly installed on the surface of the main pipe 4. An extension threaded rod 43 is slidably installed on the inner wall of the sleeve 12. A humidity sensor 7 is rotatably installed at the bottom end of the extension threaded rod 43. The humidity sensor 7 is electrically connected to the controller 13. An adjustment ring 44 is rotatably installed on the lower side of the sleeve 12. The extension threaded rod 43 is screwed onto the inner wall of the adjustment ring 44.

[0053] With the above structure, the inner wall of the sleeve 12 is annular and has two vertical surfaces to limit the extension threaded rod 43. The surface of the extension threaded rod 43 is provided with a threaded groove, and the adjusting ring 44 engages with it through the threaded groove. When the adjusting ring 44 rotates, it drives the extension threaded rod 43 to move up and down.

[0054] Furthermore, a controller 13 is fixedly installed on the inner wall of the control box 5, and a storage battery 17 is fixedly installed on the inner wall of the controller 13. The controller 13 is electrically connected to the storage battery 17 and the controller 13 is electrically connected to the drive motor 15. A lower pressure plate 9 is slidably installed on the inner wall of the water and fertilizer tank 1. A sealing strip 10 is fixedly installed on the lower side of the lower pressure plate 9. A bracket 2 is fixedly installed on the upper side of the lower pressure plate 9. A solar panel 3 is fixedly installed on the bracket 2. An inverter 8 is fixedly installed on the upper side of the lower pressure plate 9. The inverter 8 is electrically connected to the storage battery 17.

[0055] With the above structure, each control box 5 is equipped with a controller 13. The solar panel 3 converts light energy into electrical energy through the inverter 8 and sends it to the storage battery 17. The storage battery 17 supplies power to the drive motor 15 and humidity sensor 7 through the controller 13 and controls the start and stop of the drive motor 15. The bracket 2 located between the lower pressure plate 9 and the solar panel 3 is much higher than the depth inside the fertilizer tank to ensure the normal operation of the solar panel 3.

[0056] Furthermore, one end of the opening and closing head 21 is tapered, and multiple conveying ports 27 are provided at one end of the opening and closing head 21. One end of the secondary connecting pipe 22 is tapered, and a drain port 28 is provided on one side of the secondary connecting pipe 22.

[0057] With the above structure, the tapered end of the opening and closing head 21 is provided with multiple conveying ports 27 at equal intervals. When the opening and closing head 21 moves closer to the maximum position of the primary connecting pipe 16, it still fits against the inner wall of the secondary connecting pipe 22, thereby avoiding water leakage.

[0058] Working principle: When using the device, move it to the ground where the fruit trees are planted, and then manually rotate the adjustment ring 44. The adjustment ring 44 drives the extension threaded rod 43 to extend, and the extension threaded rod 43 drives the humidity sensor 7 to move downward. Adjust the height of the humidity sensor 7 in the above manner to meet the soil terrain at different heights, and insert its detection end close to the fruit tree planted in the soil to monitor the soil. Then manually separate the lower pressure plate 9 from the water and fertilizer tank 1, and then introduce the water and fertilizer to be drip-irrigated into the water and fertilizer tank 1. Then use the lower pressure plate 9 to close the inside of the water and fertilizer tank 1. Through the gravity of the lower pressure plate 9 and the inverter 8 and solar panel 3 installed on its upper side, the water and fertilizer in the water and fertilizer tank 1 are squeezed and flushed into and fill the main pipe 4, thus completing the installation of the device.

[0059] During use, the humidity sensor 7 monitors the humidity of the fruit tree soil and transmits the data to the controller 13. When the soil humidity is low, the controller 13 controls the output of the drive motor 15 to rotate. The output of the drive motor 15 drives the secondary screw 30 to rotate. The threaded groove on the surface of the secondary screw 30 drives the drive block 31 to move. The drive block 31 drives the opening and closing head 21 to move, so that the conical end of the opening and closing head 21 gradually moves away from the secondary connecting pipe 22. The opening and closing head 21 and the secondary connecting pipe 22 are opened. Water and fertilizer are delivered to the drain outlet 28 through the delivery port 27 on the opening and closing head 21 and flow into the outer pipe 6 and the guide hollow plate 11. Water and fertilizer are dripped out through the dripper 18 to irrigate the soil in this area. When the drip irrigation makes the soil reach the predetermined humidity threshold, the controller 13 drives the drive motor 15 to rotate in the opposite direction, so that the opening and closing head 21 is reset and the water and fertilizer irrigation is stopped. The outer pipe 6 and the guide hollow plate 11 are emptied to dry their interior, thus completing the intelligent water and fertilizer irrigation for fruit tree planting.

[0060] When the secondary screw 30 rotates, it simultaneously drives the transmission rod 25 to rotate. The transmission rod 25 drives the primary bevel gear 24 to rotate, which in turn drives the secondary bevel gear 26 to rotate. The secondary bevel gear 26 drives the primary screw 19 to rotate, which in turn drives the rotating tube 42 to move. The primary screw 19 also drives the lifting block 45 to move downward. The lifting block 45, through two connecting strips 41 and under the action of two guide grooves 40, drives the two filter cotton plates 38 to unfold, so that the two filter cotton plates 38 fit against the upper side of the dripper 18 to filter impurities in the water and fertilizer, preventing the dripper 18 from becoming clogged. After irrigation, the drive motor 15 reverses, at which point the filter cotton plates 38 reset and come closer together to squeeze out the water and fertilizer inside, preventing internal dampness and avoiding the growth of algae and moss.

[0061] When it is necessary to disassemble and replace the external connector 6 or remove it directly from use, first manually rotate the fixing threaded rod 36 to disengage it from the positioning ear 37, thereby releasing the limit of the mounting plate 14. Then, manually rotate the mounting plate 14. The mounting plate 14 drives the two drive rods 35 to move through the two drive ports 20. The two drive rods 35 drive the two sliders 34 to move away from each other. The two sliders 34 drive the two clamping plates 33 to move away from each other, thereby releasing the fixation of the external connector 6. Then, the external connector 6 can be removed to complete the quick disassembly.

[0062] This invention also provides a method for using an integrated water and fertilizer intelligent drip irrigation device for fruit tree planting, comprising the following steps:

[0063] S1. When using the device, first move the device to the ground where the fruit trees are planted, then adjust the height of the multiple humidity sensors 7 by adjusting the height adjustment device so that their detection ends are inserted into and close to the fruit trees planted in the soil. Separate the lower plate 9 from the water and fertilizer tank 1, then introduce the water and fertilizer that need to be drip-irrigated into the water and fertilizer tank 1, and then use the lower plate 9 to close the water and fertilizer tank 1 to complete the installation of the device.

[0064] S2. When in use, the humidity sensor 7 first monitors the humidity of the fruit tree soil and transmits the data to the controller 13. When the soil humidity is low, the controller 13 controls the drive component to move the opening and closing head 21, so that the conical end of the opening and closing head 21 gradually moves away from the secondary connecting pipe 22. At this time, the opening and closing head 21 and the secondary connecting pipe 22 are opened. Water and fertilizer are delivered to the drain outlet 28 through the delivery port 27 on the opening and closing head 21. Water and fertilizer are delivered to the drip irrigation nozzle through the secondary connecting pipe 22. Water and fertilizer are dripped through the drip irrigation nozzle to complete the drip irrigation of the fruit tree.

[0065] S3. When the drip irrigation causes the soil to reach the predetermined humidity threshold, the controller 13 drives the drive motor 15 to rotate in the opposite direction, so that the opening and closing head 21 is reset and the water and fertilizer irrigation is stopped, thereby completing the intelligent water and fertilizer irrigation for fruit tree planting.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.

3. The intelligent drip irrigation device for fruit tree planting integrating water and fertilizer as described in claim 2, characterized in that: Its usage includes the following steps: S1. When using the device, first move the device to the ground where the fruit trees are planted, then adjust the height of multiple humidity sensors (7) by adjusting the height adjustment device so that their detection ends are inserted into and close to the fruit trees planted in the soil. Separate the pressure plate (9) from the water and fertilizer tank (1), then introduce the water and fertilizer that need to be drip-irrigated into the water and fertilizer tank (1), and then use the pressure plate (9) to close the water and fertilizer tank (1) to complete the installation of the device. S2. When in use, the humidity sensor (7) is used to monitor the humidity of the soil of the fruit tree and transmit the data to the controller (13). When the soil humidity is low, the controller (13) controls the drive component to drive the opening and closing head (21) to move, so that the conical end of the opening and closing head (21) gradually moves away from the secondary connecting pipe (22). At this time, the opening and closing head (21) and the secondary connecting pipe (22) are opened. Water and fertilizer are delivered to the drain outlet (28) through the delivery port (27) on the opening and closing head (21). Water and fertilizer are delivered to the drip irrigation nozzle through the secondary connecting pipe (22). Water and fertilizer are dripped through the drip irrigation nozzle to complete the drip irrigation of the fruit tree. S3. When the drip irrigation causes the soil to reach the predetermined humidity threshold, the controller (13) drives the drive motor (15) to rotate in the opposite direction, so that the opening and closing head (21) is reset and the water and fertilizer irrigation is stopped, thereby completing the intelligent water and fertilizer irrigation for fruit tree planting.
