Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable hydration, specifically to an Internet of Things-based drip-type hydration device for fruit trees. Background Technology

[0002] The main purpose of fruit tree drip irrigation is to supplement nutrition, promote growth, and prevent and control pests and diseases. By providing fruit trees with necessary nutrients, this technique has less environmental pollution, direct efficacy, and is an effective way to maintain the normal metabolism of fruit trees.

[0003] However, current fruit tree hanging bags are not reusable, resulting in high costs when using them for sap replenishment. Furthermore, the bags are disposable, meaning that not only must they be installed, but they also need to be removed after replenishment. Fruits and vegetables require replenishment about 2-3 times a year, leading to a large workload and high costs. Moreover, the flow rate can only be adjusted manually via valves on the drip needles, making it difficult to manage when adjusting the sap replenishment efficiency of multiple bags. This adjustment process undoubtedly increases the workload significantly, and real-time control and monitoring of the flow rate are not possible.

[0004] During hydration treatment of fruit trees, appropriate pressure is required for the hydration solution to penetrate the tree effectively. However, excessive pressure inside the drip bag can damage it and cause leakage. Furthermore, the drip bag and end cap may detach during the pressurization process. Increased pressure inside the drip bag also increases the pressure on the drip needle, potentially causing the needle to detach from the tree. When not in use, the drip needle should be removed from the fruit and placed under the drip bag to prevent it from growing into the tree after hydration. Summary of the Invention

A rod groove is provided inside the outer valve body, and a locking rod is provided inside the rod groove. A first elastic element is sleeved on the locking rod, and the first elastic element is used to push the locking rod to reset.

[0014] (1) The liquid replenishment system is connected by liquid pipelines. The liquid replenishment system can deliver liquid to the corresponding fruit trees. The hanging bags are then connected to the liquid replenishment system. The liquid replenishment system is equipped with solenoid valves, which can be connected via a mobile APP to control the liquid flow rate inside the liquid replenishment system. The flow rate of the liquid replenishment system can also be remotely controlled. The hanging bags can be reused, saving costs. The hanging bags also have a certain pressure resistance to prevent them from breaking during the liquid replenishment process. The hanging bags and the liquid replenishment system are separated by the cooperation of the connecting mechanism and the locking mechanism. When it is necessary to separate the connecting mechanism and the locking mechanism, the unlocking component is activated. The unlocking component blocks the connecting mechanism and pushes the connecting mechanism to separate the connecting mechanism from the locking mechanism. This allows the liquid replenishment system to separate under pressure. When separated, the connecting mechanism closes, and the liquid inside the hanging bag is sealed. The limiting mechanism moves out of the inside of the hanging needle and locks inside the fruit tree when pressurized, so that the hanging needle will not separate from the fruit tree when pressurized.

[0015] (2) The unlocking mechanism can unlock the outer valve body and the inner valve body when they need to be separated. Rotate the push rod and move it until it is pressed under the stop bar and slides under the stop bar to the other side of the stop bar. At this time, the stop bar is limited. When the push rod needs to be reset, move the toggle block upward. The toggle block moves the stop bar upward, so that the push rod enters the end of the slide groove, so that the through groove and the injection groove are aligned. At this time, the reset connection is completed. The process is simple and easy to operate, and can effectively unlock and lock the connection between the outer valve body and the inner valve body.

[0016] (3) When the injection pressure increases, more liquid flows into the guide channel, pushing the elastic plate to move. The two ends of the elastic plate are fixed inside the needle, causing deformation. The elastic plate changes from concave to convex on both sides, driving the squeezing block to move. The squeezing block presses against the limiting rod, which rotates around the pivot pin. The rotation of the limiting rod causes the abutment block to move, becoming stuck inside the fruit tree. At this point, when the limiting rod rotates to its maximum angle, the limiting block is now in place. When the pressure inside the needle is too high, the needle will have a backward thrust. When the needle needs to be removed, the limiting block prevents the limiting rod from deforming due to excessive rotation angle. When the needle needs to be removed, the needle is pushed to move inside the fruit tree. At this time, the fruit tree squeezes the limiting rod, and the limiting rod will be completely retracted until it returns to its original position under the squeezing force. When the limiting rod returns to its original position, the limiting rod pushes the elastic plate from protruding to concave. At this time, the elastic plate pulls the sixth elastic element to return to its original position. The sixth elastic element is now in its natural state. The sixth elastic element pulls the limiting rod to prevent the limiting rod from rotating outward from the needle during the outward pulling process and getting stuck inside the fruit tree, making the disassembly process more convenient.

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] In one embodiment, please refer to the appendix to the specification. Figure 1-10As shown, the present invention discloses an IoT-based drip-type sapling device for fruit trees, comprising a drip bag 1, wherein the drip bag 1 is provided with a locking mechanism 2 connected to a sapling system, the locking mechanism 2 being used to connect the sapling system to input the sap into the drip bag 1; the drip bag 1 is provided with a connecting mechanism 5, which is installed inside the locking mechanism 2, and when the connecting mechanism 5 is disassembled, the drip bag 1 is separated from the sapling system; the drip bag 1 is provided with a sapling tube 3, and multiple drip needles 4 are provided at the end of the sapling tube 3, the drip needles 4 being used to insert into the fruit tree for sapling, and the drip needles 4 being provided with a limiting mechanism 7, the limiting mechanism 7 preventing the drip needles 4 from separating from the fruit tree; the locking mechanism 2 is provided with an unlocking component 6, the unlocking component 6 being used to push the locking mechanism 2 and the connecting mechanism 5 apart.

[0031] The liquid replenishment system is connected via liquid pipelines, delivering liquid to the corresponding fruit trees. Hanging bags 1 are then connected to the system, which is equipped with solenoid valves. These valves can be connected via a mobile app to control the liquid flow rate within the system and allow for remote control of the flow rate. The hanging bags 1 are reusable, saving costs, and possess a certain degree of pressure resistance to prevent breakage during replenishment. A connecting mechanism 5 and a locking mechanism 2 work together to separate the hanging bags 1 from the replenishment system. When separation is required, an unlocking component 6 is activated. This component seals the connecting mechanism 5 and simultaneously pushes the connecting mechanism 5 away from the locking mechanism 2, enabling the replenishment system to separate under pressure. During separation, the connecting mechanism 5 closes, sealing the liquid inside the hanging bags 1. When pressure is applied, the limiting mechanism 7 moves out of the inside of the needle 4 and locks inside the fruit tree, so that the needle 4 will not separate from the fruit tree when pressure is applied.

[0032] The connecting mechanism 5 includes an inner valve body 51 disposed at the top of the hanging bag 1. A support plate 52 is disposed inside the inner valve body 51, and the support plate 52 has multiple openings. A third elastic element 53 is disposed below the support plate 52, and a movable plate 54 is disposed below the third elastic element 53. The third elastic element 53 is used to push the movable plate 54 to reset. An arc groove 55 is disposed on the lower surface of the movable plate 54. A sealing ring 56 is disposed at the bottom of the inner valve body 51. The sealing ring 56 and the arc groove 55 are pressed and sealed together. An outer spiral 58 is disposed on the inner valve body 51. A through groove 511 is disposed at the bottom of the inner valve body 51. An ejection component 57 is disposed inside the inner valve body 51, and the ejection component 57 is located in the gap of the outer spiral 58. The ejection component 57 is engaged with the locking mechanism 2. The connecting mechanism 5 also includes elastic plates 510 disposed on both sides of the through groove 511. A rubber pad 512 is disposed at the bottom of the elastic plate 510. The rubber pad 512 has a corrugated structure. A fifth elastic element 513 is disposed inside the elastic plate 510. The elastic plate 510 and the rubber pad 512 form a sealed inner cavity 59. The inner cavity 59 is filled with hydraulic oil. When the elastic plate 510 moves and squeezes the inner cavity 59, the hydraulic oil in the inner cavity 59 enters the interior of the ejector assembly 57. The ejector assembly 57 moves and enters the interior of the locking mechanism 2. The ejection assembly 57 includes a chamber 573 and an oil groove 571 disposed on the inner valve body 51. One end of the oil groove 571 extends into the inner cavity 59, and the other end communicates with the chamber 573. A fourth elastic element 572 is disposed inside the chamber 573. A push rod 575 is disposed inside the chamber 573. A reserved groove 574 is disposed above the push rod 575. The reserved groove 574 communicates with the chamber 573. The push rod 575 is sleeved inside the fourth elastic element 572. The fourth elastic element 572 is used to push the push rod 575 to reset.

[0033] The connecting mechanism 5 is connected to the engaging mechanism 2. When it is necessary to connect the engaging mechanism 2 and the connecting mechanism 5, the engaging mechanism 2 is rotated, and the engaging mechanism 2 and the connecting mechanism 5 engage in a spiral manner. When the engaging mechanism 2 and the connecting mechanism 5 are connected in place, the ejector component 57 engages with the engaging mechanism 2. The movable plate 54 is pushed upward by the engaging mechanism 2, and the movable plate 54 moves upward and is compressed by the third elastic element 53, so that the through groove 511 is opened. When the through groove 511 is opened, the liquid can flow from the inside of the inner valve body 51. In order to allow the liquid to enter the inside of the fruit tree, the flow rate of the solenoid valve needs to be increased, which increases the pressure inside the inner valve body 51. When the pressure of the liquid inside the through groove 511 is increased, the liquid will squeeze the elastic plate 510. The elastic plate 510 is squeezed and moves by the liquid. When the elastic plate 510 moves, the elastic plate 510 drives the rubber pad 512 to move. The movement of the rubber pad 512 compresses the inner cavity 59, causing it to contract. This compresses the hydraulic oil inside the inner cavity 59, which then enters the oil groove 571. The hydraulic oil in the oil groove 571 enters the chamber 573, pushing the push rod 575. As the push rod 575 moves, the fourth elastic element 572 is stretched, and the push rod 575 moves outward from the chamber 573, entering the locking mechanism 2. At this point, the locking mechanism 2 and the inner valve body 51 are fixed. As the liquid pressure continues to increase, the elastic plate 510 continues to move, further compressing the hydraulic oil inside the oil groove 571. The hydraulic oil pushes the push rod 575, which continues to move into the locking mechanism 2 until the push rod 575 is pushed past the reserved groove 574. The reserved groove 574 and the chamber 573 then connect, and the hydraulic oil enters the reserved groove 574 from the chamber 573.

[0034] When the locking mechanism 2 is disassembled from the inner valve body 51, the bottom of the movable plate 54 does not contact the locking mechanism 2. Under the push of the third elastic element 53, the movable plate 54 moves down and causes the arc groove 55 to fit against the sealing ring 56. The sealing ring 56 is squeezed, so that the arc groove 55 is blocked by the sealing ring 56. At this time, the through groove 511 is blocked, the elastic plate 510 is not squeezed by the liquid pressure, the elastic plate 510 is reset, the fifth elastic element 513 is reset, and the inner cavity 59 is reset under the push of the fifth elastic element 513 and the elastic action of the elastic plate 510 itself. The hydraulic oil in the inner cavity 59 enters the interior of the inner cavity 59, and the hydraulic oil located inside the reserved groove 574 flows back.

[0035] The engaging mechanism 2 includes an outer valve body 21 that screws into the inner valve body 51. A spiral groove 29 is formed on the inner wall of the outer valve body 21, which engages with the outer spiral 58. A rod groove 23 is provided inside the outer valve body 21, and a locking rod 22 is disposed inside the rod groove 23. A first elastic element 24 is sleeved on the locking rod 22, and the first elastic element 24 is used to push the locking rod 22 to reset. A pressing rod 25 is provided inside the outer valve body 21. The squeeze rod 25 abuts against the clamping rod 22. The bottom of the squeeze rod 25 is provided with an adjusting component 26 that cooperates with it. The adjusting component 26 is used to adjust the position of the clamping rod 22. The bottom of the outer valve body 21 is provided with a base plate 27. The base plate 27 is provided with an abutting rod 28. The abutting rod 28 abuts against the movable plate 54. The base plate 27 is provided with a plurality of injection grooves 210. The adjusting component 26 adjusts the flow rate of the injection grooves 210 simultaneously when adjusting the position of the clamping rod 22. The adjusting assembly 26 includes a sealing plate 261 disposed inside the outer valve body 21. The sealing plate 261 has multiple through holes 263 that cooperate with the injection groove 210. The sealing plate 261 has a lifting block 262 with an arc-shaped structure and an inclined surface. The top of the lifting block 262 abuts against the extrusion rod 25. The outer valve body 21 has a block groove 264 inside, and the lifting block 262 slides inside the block groove 264.

[0036] The inner valve body 51 and outer valve body 21 can be easily disassembled by the combination of the spiral groove 29 and the outer spiral 58; when the liquid pressure increases, the hanging bag 1 will detach from the liquid replenishment system; in order to keep the hanging bag 1 suspended on the liquid replenishment system during liquid pressurization; so that the inner valve body 51 and outer valve body 21 are tightened during the pressurization process, and the connection between the inner valve body 51 and outer valve body 21 becomes stronger as the pressurization pressure increases; when the outer valve body 21 and inner valve body 51 are rotated into place, the push rod 575 is just aligned with the locking rod 2. 2. Initially, the locking rod 22 is located inside the rod groove 23. When the push rod 575 is squeezed into the rod groove 23, the push rod 575 is locked inside the rod groove 23. Since the outer screw 58 and the threaded groove are screw-fitted, the push rod 575 is limited at this time, so that the outer valve body 21 and the inner valve body 51 will not separate, and thus are limited. When the liquid pressure inside the inner valve body 51 increases, the length of the push rod 575 that pushes into the rod groove 23 increases, making it more difficult for the push rod 575 to separate from the rod groove 23, thereby achieving the locking effect.

[0037] When it is necessary to separate the inner valve body 51 and the outer valve body 21, the top of the hanging bag 1 must be sealed after separation to prevent the liquid inside the hanging bag 1 from leaking or becoming contaminated. Rotating the unlocking component 6 causes the sealing plate 261 to rotate inside the outer valve body 21. During the rotation of the sealing plate 261, the through hole 263 and the injection groove 210 are misaligned, completely sealing the injection groove 210. At this time, the top of the hanging bag 1 is sealed. When rotating the sealing plate 261, the sealing plate 261 drives the lifting block 262 to rotate synchronously. The rotation of the lifting block 262 pushes the squeezing rod 25 upwards. After the squeezing rod 25 is pushed upwards, the squeezing rod 25 pushes... The movable lever 22 moves until its end is just at the end of the lever groove 23. When the lever 22 moves, it pushes the top rod 575 to reset until the top rod 575 is just separated from the lever groove 23. At this time, the outer valve body 21 is rotated to remove it from the inner valve body 51. This process is simple to operate and can seal the top port of the hanging bag 1 and release the lock between the outer valve body 21 and the inner valve body 51. Even when the liquid replenishment system is pressurized, the hanging bag 1 can be installed and removed, which is convenient for replacing the hanging bag 1. Liquid replenishment can be carried out quickly during the replacement process, improving the liquid replenishment efficiency.

[0038] The unlocking component 6 includes a slide groove 62 formed on the outer valve body 21, a slot 63 provided above the slide groove 62, and a push rod 61 slidably disposed inside the slide groove 62; a clearance groove 67 provided above the slide groove 62, a stop rod 64 provided inside the clearance groove 67, a toggle block 65 provided on the outer wall of the stop rod 64, a sixth elastic element 66 provided on the top of the stop rod 64, the sixth elastic element 66 being used to push the stop rod 64 to reset, the bottom of the stop rod 64 being an inclined surface, and the push rod 61 moving to press the stop rod 64.

[0039] The unlocking mechanism allows for the unlocking of the outer valve body 21 and the inner valve body 51 when separation is required. Rotating the push rod 61 moves it until it presses against the bottom of the stop rod 64 and slides under it, entering the other side of the stop rod 64. At this point, the stop rod 64 is limited. When the push rod 61 needs to be reset, the toggle block 65 moves upward, causing the stop rod 64 to move upward, allowing the push rod 61 to enter the end of the slide groove 62, aligning the through groove 511 with the injection groove 210. This completes the reset connection. The process is simple, easy to operate, and effectively unlocks and locks the connection between the outer valve body 21 and the inner valve body 51.

[0040] The limiting mechanism 7 includes a limiting rod 71 rotatably mounted on the drip needle 4. An abutment block 72 is provided at the end of the limiting rod 71. A pin groove 74 is formed on the limiting rod 71, and a pivot pin 73 is rotatably mounted inside the pin groove 74. A torsion spring is provided on the pivot pin 73, which is used to push the limiting rod 71 back to its original position. A seventh elastic element 79 and an elastic sheet 76 are provided inside the drip needle 4. One end of the seventh elastic element 79 is connected to the limiting rod 71, and the other end abuts against the elastic sheet 76. A squeezing block 77 is provided on the elastic sheet 76. A flow guide groove 78 is provided between the two elastic sheets 76, and the flow guide groove 78 communicates with the replenishment tube 3. A limiting block 75 is provided inside the drip needle 4, which is used to limit the rotation angle of the limiting rod 71.

[0041] To ensure the injection liquid quickly penetrates the fruit tree, pressurization is typically used to apply pressure, allowing the liquid to rapidly flow from the infusion needle 4 into the tree. However, as the pressure increases, the infusion needle 4 may detach from the tree. Given the large number of trees in the orchard, reinstalling the infusion needle 4 after it detaches requires significant manpower. Therefore, a limiting mechanism 7 directly secures the infusion needle 4 to the fruit tree, preventing it from separating during pressurization and ensuring efficient injection. When the injection pressure increases, more liquid flows into the guide channel 78, pushing the elastic plate 76 to move. The two ends of the elastic plate 76 are fixed inside the needle 4, causing the elastic plate 76 to deform, changing from concave to convex. The elastic plate 76 drives the squeezing block 77 to move, squeezing it against the limiting rod 71. The limiting rod 71 rotates around the pivot pin 73, causing the abutment block 72 to move and become locked inside the fruit tree. At this point, when the limiting rod 71 rotates to its maximum angle, the limiting block 75, now limiting the rod 71's rotation, causes excessive pressure inside the needle 4, resulting in a backward thrust in the needle 4. At this time, the limiting block 75 prevents the limiting rod 71 from deforming due to excessive rotation angle. When it is necessary to disassemble the hanging needle 4, the hanging needle 4 is pushed to move inside the fruit tree. At this time, the fruit tree squeezes the limiting rod 71, and the limiting rod 71 will be completely retracted under the squeezing force until it is reset. When the limiting rod 71 is reset, the limiting rod 71 pushes the elastic piece 76 from protruding to concave. At this time, the elastic piece 76 pulls the sixth elastic element 66 to reset. The sixth elastic element 66 is now in its natural state. The sixth elastic element 66 pulls the limiting rod 71 to prevent the limiting rod 71 from rotating outward from the hanging needle 4 during the outward pulling process and being stuck inside the fruit tree, making the disassembly process more convenient.

[0042] In use, the sap replenishment system is first installed on the fruit tree. The system can be adjusted via a mobile phone to control the flow rate and enable real-time monitoring. The hanging bag 1 is then installed on the sap replenishment system. The outer valve body 212 is rotated so that the spiral groove 29 and the outer spiral 58 on the outer valve body 21 engage. When the outer valve body 21 and the inner valve body 51 are rotated into place, the push rod 575 aligns perfectly with the locking rod 22. Initially, the locking rod 22 is located inside the rod groove 23. When the push rod 575 is squeezed into the rod groove 23, it is locked inside. Since the outer spiral 58 and the threaded groove are spirally engaged, the push rod 575 is now limited, preventing the outer valve body 21 and the inner valve body 51 from separating and thus limiting their movement. When it is necessary to separate the inner valve body 51 and the outer valve body 21, rotate the push rod 61. The push rod 61 moves until it presses against the bottom of the stop rod 64 and slides under the stop rod 64, entering the other side of the stop rod 64. The push rod 61 drives the sealing plate 261 to rotate inside the outer valve body 21. During the rotation of the sealing plate 261, the through hole 263 and the injection groove 210 will be misaligned, so that the injection groove 210 is completely blocked. At this time, the top of the hanging bag 1 is blocked. When rotating the sealing plate 26... At time 1, the sealing plate 261 drives the lifting block 262 to rotate synchronously. The rotation of the lifting block 262 pushes the extrusion rod 25 upward. When the extrusion rod 25 is pushed upward, the extrusion rod 25 pushes the locking rod 22 to move until the end of the locking rod 22 just moves to the end of the rod groove 23. When the locking rod 22 moves, the locking rod 22 pushes the top rod 575 to reset until the top rod 575 just separates from the rod groove 23. At this time, the outer valve body 21 is rotated so that the outer valve body 21 is removed from the inner valve body 51.When the engaging mechanism 2 and the connecting mechanism 5 need to be connected in place, the push rod 575 engages with the rod groove 23; the movable plate 54 is pushed upward by the engaging mechanism 2, and the movable plate 54 moves upward and the third elastic element 53 is compressed, so that the through groove 511 is opened. When the through groove 511 is opened, the liquid can flow from the inside of the inner valve body 51; in order to allow the liquid to enter the inside of the fruit tree, the flow rate of the solenoid valve needs to be increased, which in turn increases the pressure inside the inner valve body 51. When the pressure of the liquid inside the through groove 511 is increased, the liquid will squeeze the elastic plate 510. The elastic plate 510 moves under the pressure of the liquid. When the elastic plate 510 moves, the elastic plate 510 drives the rubber pad 512 to move. The movement of the rubber pad 512 will squeeze the inner cavity 59, the inner cavity 59 will contract, and the hydraulic oil inside the inner cavity 59 will be squeezed. Hydraulic oil is compressed and enters the interior of oil tank 571. The hydraulic oil inside oil tank 571 enters the interior of chamber 573. The hydraulic oil pushes the push rod 575 to move. When the push rod 575 moves, the fourth elastic element 572 is stretched, and the push rod 575 moves outward from the interior of chamber 573 and enters the interior of locking mechanism 2. At this time, locking mechanism 2 and inner valve body 51 are fixed. When the liquid pressure continues to increase, elastic plate 510 continues to move. The movement of elastic plate 510 continues to squeeze the hydraulic oil inside oil tank 571. The hydraulic oil pushes the push rod 575 and continues to move into the interior of locking mechanism 2 until the push rod 575 is pushed past the bottom of reserved groove 574. Reserved groove 574 and chamber 573 are connected, and hydraulic oil enters the interior of reserved groove 574 from chamber 573. When the locking mechanism 2 is disassembled from the inner valve body 51, the bottom of the movable plate 54 does not contact the locking mechanism 2. Under the push of the third elastic element 53, the movable plate 54 moves down and causes the arc groove 55 to fit against the sealing ring 56. The sealing ring 56 is squeezed, so that the arc groove 55 is blocked by the sealing ring 56. At this time, the through groove 511 is blocked, the elastic plate 510 is not squeezed by the liquid pressure, the elastic plate 510 is reset, the fifth elastic element 513 is reset, and the inner cavity 59 is reset under the push of the fifth elastic element 513 and the elastic action of the elastic plate 510 itself. The hydraulic oil in the inner cavity 59 enters the interior of the inner cavity 59, and the hydraulic oil located inside the reserved groove 574 flows back.When the injection pressure increases, more liquid flows into the guide channel 78, pushing the elastic plate 76 to move. The two ends of the elastic plate 76 are fixed inside the needle 4, causing the elastic plate 76 to deform, changing from concave to convex. The elastic plate 76 drives the squeezing block 77 to move, squeezing it against the limiting rod 71. The limiting rod 71 rotates around the pivot pin 73, causing the abutment block 72 to move and become lodged inside the fruit tree. At this point, when the limiting rod... After the rod 71 rotates to its maximum angle, the limiting block 75 now limits the rotation of the rod 71. When the pressure inside the needle 4 is too high, the needle 4 will have a backward pushing force. At this time, the limiting block 75 prevents the limiting rod 71 from rotating too much and deforming. When it is necessary to disassemble the needle 4, push the needle 4 to move inside the fruit tree. At this time, the fruit tree squeezes the limiting rod 71. The limiting rod 71 will be completely retracted under the squeezing force until it is reset. When the limiting rod 71 is reset, the limiting rod 71 pushes the elastic piece 76 from protruding to concave.
