[0054] In the process of garden plant cultivation, watering is a vital task. In order for plants to grow healthily, we need to carefully arrange and manage the irrigation system, which includes selecting suitable water sources, such as groundwater, river water or rainwater collection systems, and adjusting the frequency and amount of watering according to the specific needs of plants and weather conditions. In addition, modern technology also widely uses drip irrigation, sprinkler irrigation and other water-saving technologies to improve the utilization efficiency of water resources and reduce waste. However, when irrigation is carried out in a large area of ​​plant planting, due to the wide planting range and the difference in soil moisture in various places, the drip irrigation process may cause over-irrigation or under-irrigation, resulting in waste of water resources or causing plant drought.

[0055] In order to solve this technical problem, the present invention provides a plant cultivation drip irrigation device to solve the problem that the existing device over-irrigates or under-irrigates, thereby causing waste of water resources or causing plant drought.

[0056] See also Figure 1The plant cultivation drip irrigation device 100 includes a storage barrel 1, a liquid inlet pipe, an irrigation device 2 and a detection device. The storage barrel 1 has an inner cavity 11 for storing nutrient solution. The upper end surface of the storage barrel 1 is provided with a first liquid inlet hole 12 and a water inlet hole 13, and the outer wall of the storage barrel 1 is provided with a discharge hole 14; the end of the liquid inlet pipe extends into the inner cavity 11 from the first liquid inlet hole 12; the irrigation device 2 includes a mainstream pipe 21 and a plurality of branch pipes 22 connected to the mainstream pipe 21, the mainstream pipe 21 is connected to the discharge hole 14, and each of the branch pipes 22 is provided with an irrigation hole 221 for transporting the nutrient solution in the inner cavity 11 to the irrigation area; the detection device includes a temperature and humidity sensor 3 arranged on the branch pipe 22 for detecting the temperature and humidity of the irrigation area.

[0057] In the technical solution provided by the present invention, when the temperature and humidity sensor 3 senses that the planting land in the irrigation area is too dry, the nutrient solution in the storage barrel 1 will enter the corresponding tributary pipe 22, and finally irrigate the planting land from the irrigation hole 221 on the tributary pipe 22, so that the humidity of the planting land increases; when the temperature and humidity sensor 3 senses that the humidity reaches a suitable value, the corresponding tributary pipe 22 is closed, so that the nutrient solution no longer enters the planting land in the area, so as to achieve the effect of saving water. Therefore, the plant cultivation drip irrigation device 100 provided by the present application can control the connectivity of the corresponding tributary pipe 22 according to the temperature and humidity of the planting land, thereby automatically controlling the irrigation amount of different irrigation areas, thereby avoiding the negative impact of excessive or insufficient irrigation on the growth of plants.

[0058] It should be noted that the water inlet hole 13 is used to transport water into the storage barrel 1, and the first liquid inlet hole 12 is used to transport nutrient solution into the storage barrel 1, so that the nutrient solution and water are mixed in the storage barrel 1 to obtain nutrient solution for irrigating the planting land. In addition, the end of the liquid inlet pipe extends from the first liquid inlet hole 12 into the inner cavity 11, and the water inlet pipe can also be used to transport water into the inner cavity 11 through the water inlet hole 13.

[0059] It is understandable that the plurality of branch pipes 22 may be on the same side of the main pipe 21, or may be distributed on opposite sides of the main pipe 21. In addition, a water pump 23 may be provided on the main pipe 21 to provide more sufficient power for the irrigation device 2, and solenoid valves may be provided on the main pipe 21 and each branch pipe 22 to control the on-off of the pipes.

[0060] The sizes of the mainstream pipe 21, the branch pipe 22 and the storage barrel 1 in the present application can be determined according to actual conditions. By distributing the branch pipe 22 on the planting ground where the plants are planted, and inserting the conical temperature and humidity sensor 3 into the ground, water and nutrient solution are injected into the storage barrel 1 from the water inlet hole 13 and the first liquid inlet hole 12. When the temperature and humidity sensor 3 senses that the ground is too dry, the water pump 23 is started and the solenoid valve is opened. At this time, the water in the storage barrel 1 will enter the mainstream pipe 21, and then enter the branch pipe 22, and finally from the branch pipe 23. The irrigation holes 221 on the tributary pipe 22 drip irrigation to the planting ground, so that the humidity of the planting ground increases; when the temperature and humidity sensor 3 senses that the humidity has reached an appropriate value, the solenoid valve on the corresponding tributary pipe 22 can be closed to prevent water from entering the planting ground in this area. When the values ​​sensed by all temperature and humidity sensors 3 meet the requirements, the water pump 23 will be turned off. The device can achieve the effect of automatic drip irrigation of the plant planting ground. At the same time, the automatic opening and closing of the tributary pipe 22 can be controlled according to the humidity of the planting ground to achieve the effect of saving water.

[0061] In some embodiments of the present invention, please refer to Figure 2 The plant cultivation drip irrigation device 100 further includes a stirring device 4, which is disposed in the inner cavity 11 of the storage barrel 1. The stirring device 4 includes a rotating shaft 41 and a plurality of blades 42. The rotating shaft 41 is coaxially disposed with the storage barrel 1 and is rotatably mounted along an axis extending in the vertical direction; the plurality of blades 42 are disposed on the outer side wall of the rotating shaft 41, and the plurality of blades 42 are arranged along the axial direction of the rotating shaft 41. When water and nutrient stock solution are added to the storage barrel 1, the rotating shaft 41 can be controlled to rotate, and at this time, the blades 42 will stir and mix the water and nutrient stock solution in the storage barrel 1 to improve the irrigation effect of the planting area.

[0062] It should be noted that the stirring device 4 also includes a motor to provide power for the rotation of the rotating shaft 41. The motor can be arranged outside the storage barrel 1 or inside the storage barrel 1. When the motor is arranged inside the storage barrel 1, a waterproof protective shell can be used to protect the motor.

[0063] For further information, please refer to Figure 3 and Figure 4The rotating shaft 41 is provided with a cavity 411 inside, and the side wall of the rotating shaft 41 is provided with a plurality of water outlet holes 412 connected to the cavity 411; the plant cultivation drip irrigation device 100 also includes a mixing device 5, and the mixing device 5 includes a mixing piece 51 and a barrier 52; the mixing piece 51 has an inner side wall 511 close to the rotating shaft 41 and an outer side wall 512 away from the rotating shaft 41, the mixing piece 51 is arranged on the outer peripheral side of the rotating shaft 41 and is fixedly connected to the bottom of the inner cavity 11, the inner hollow of the mixing piece 51 forms an accommodating cavity 513, and the inner side wall 511 of the mixing piece 51 is partially connected to the side wall of the rotating shaft 41, A mixing hole 514 is provided at the connection to connect the cavity 411 with the accommodating cavity 513; the barrier 52 is movably sealed in the accommodating cavity 513, and the barrier 52 divides the accommodating cavity 513 into a gas accommodating cavity and a liquid accommodating cavity, wherein the liquid accommodating cavity is arranged close to the rotating shaft 41 for storing nutrient solution, and the gas accommodating cavity is used to connect with the external air, and the barrier 52 has a radial sliding movement stroke along the rotating shaft 41 to adjust the pressure in the gas accommodating cavity and the liquid accommodating cavity, so that the nutrient solution can flow in the liquid accommodating cavity, the rotating shaft cavity 411 and the storage barrel inner cavity 11.

[0064] It should be noted that the barrier 52 is sealed and slidably arranged with the inner wall of the mixing element 51, so that there is no flow between the gas accommodating chamber and the liquid accommodating chamber. When the barrier 52 moves in a direction away from the rotating shaft 41, the barrier 52 compresses the space of the gas accommodating chamber and absorbs more nutrient solution into the liquid accommodating chamber; when the barrier 52 moves in a direction away from the rotating shaft 41, the nutrient solution is ejected from the liquid accommodating chamber through the inner cavity 11 and the water outlet 412 on the side wall of the rotating shaft 41, so that the water in the storage barrel 1 fluctuates, thereby improving the mixing efficiency between the water and the nutrient solution.

[0065] Furthermore, the mixing device 5 also includes an air inlet pipe 53, one end of which is connected to the gas containing chamber, and the other end extends out of the barrel body to connect to the outside air. The other end of the air inlet pipe 53 can extend from the upper end surface of the storage barrel 1, or from the side wall of the storage barrel 1. The pressure balance in the containing chamber can be better maintained by the air inlet pipe 53. When the barrier 52 moves in a direction away from the rotating shaft 41, the barrier 52 compresses the space of the gas containing chamber, and makes the liquid containing chamber 513 have a larger space, and the air in the gas containing chamber is discharged from the air inlet pipe 53; when the barrier 52 moves in a direction away from the rotating shaft 41, the barrier 52 sucks the outside air from the air inlet pipe 53 into the gas containing chamber, and compresses the space in the liquid containing chamber 513 to spray the nutrient solution from the water outlet 412 on the side wall of the rotating shaft 41.

[0066] The mixing device 5 also includes a driving component for driving the blocking member 52 to slide, and the driving component includes a first magnetic block 54 and a first elastic member 55. The first magnetic block 54 is arranged on the outer wall of the rotating shaft 41 and is arranged corresponding to the blocking member 52 in the radial direction of the rotating shaft 41. The first magnetic block 54 and the mixing hole 514 are staggered in the up and down directions. A first magnetic member is provided in the blocking member 52, so that when the first magnetic block 54 rotates to correspond to the radial direction of the blocking member 52, the blocking member 52 moves toward the first magnetic block 54, and the two ends of the first elastic member 55 are respectively connected to the outer wall 512 of the mixing member 51 and the blocking member 52 to reset the blocking member 52.

[0067] When the rotating shaft 41 rotates, the first magnetic block 54 will intermittently pass through the blocking member 52. When the first magnetic block 54 approaches the blocking member 52, the blocking member 52 moves toward the first magnetic block 54, that is, the blocking member 52 moves in the direction close to the rotating shaft 41, and the first elastic member 55 is stretched; when the first magnetic block 54 rotates away from the blocking member 52, the blocking member 52 moves in the direction away from the rotating shaft 41 under the pulling force of the first elastic member 55. Therefore, during the rotation of the rotating shaft 41, the blocking member 52 is cyclically attracted by the first magnetic block 54 and moves back and forth, so that the water in the liquid containing chamber can be continuously pushed, so that the water in the storage barrel 1 can continuously fluctuate. In this way, under the rotation of the rotating shaft 41, the blocking member 52 can be repeatedly moved without the need for other power mechanisms.

[0068] It should be noted that the first elastic member 55 can also be arranged between the inner side wall 511 of the mixing member 51 and the barrier member 52. However, such an arrangement requires, firstly, the use of a spring, which is an elastic member that can be compressed, which has more restrictions, and secondly, the life of the elastic member in aqueous solution is lower than that in air. Arranging the first elastic member 55 between the outer side wall 512 of the mixing member 51 and the barrier member 52 can not only provide more elastic member options, but also increase the life of the elastic member. It is understandable that in the present application, the first elastic member is a spring or an elastic rope.

[0069] It should be noted that, in some other embodiments, the barrier member 52 may be made of a magnetic material to form the first magnetic member. This application is not limited here. In addition, the first magnetic block 54 may be protrudingly provided on the outer side wall of the rotating shaft 41, and in some other embodiments, the outer side wall of the rotating shaft 41 is concave toward the center of the rotating shaft 41 near the connecting groove to form a first groove, and the first magnetic block 54 is provided in the first groove. Such a configuration will not take up additional space, and the surface area of ​​the first magnetic block 54 exposed in the nutrient solution will be smaller, which is conducive to extending the service life of the device.

[0070] Furthermore, a balancing hole 413 connected to the cavity 411 is provided at the bottom of the rotating shaft 41. The plant cultivation drip irrigation device 100 also includes a first monitoring structure 6, which includes a support rod 61, a floating ring 62 and a sensor. The support rod 61 is arranged in the inner cavity 11 along the up and down direction, and one end is fixedly connected to the bottom wall of the inner cavity 11; the floating ring 62 is sleeved on the outer surface of the support rod 61 and can slide along the support rod 61; the sensor has two sensing ends, which are respectively arranged at the bottom of the floating ring 62 and the bottom wall of the inner cavity 11, so as to issue an early warning message when the floating ring 62 slides to the contact of the two sensing ends. In the presence of the balancing hole 413, when the liquid level in the inner cavity 11 of the storage barrel 1 decreases, the liquid level in the cavity 411 of the rotating shaft 41 will also decrease, and then the floating ring 62 will also move downward with the liquid surface. When the water level in the storage barrel 1 drops to the lowest point, the water in the cavity 411 of the rotating shaft 41 will be discharged from the balance hole 413. At this time, the sensing end on the floating ring 62 will contact the sensing end on the bottom wall of the inner cavity 11 and trigger an alarm message. The alarm message can be transmitted to the staff's mobile phone in the form of an APP to remind the staff to add water to the storage barrel 1 in time.

[0071] In some embodiments, the storage barrel 1 comprises a barrel body and a cover body which are sealed and connected, the cover body is sealed and covered on the barrel mouth of the barrel body, the cover body is provided with a first liquid inlet hole 12 and a water inlet hole 13, and the outer wall of the barrel body is provided with a discharge hole 14. The barrel body and the cover body are detachable so as to clean and repair the components in the storage barrel.

[0072] Please refer to Figure 5 The plant cultivation drip irrigation device 100 also includes a liquid storage component 7, which includes a liquid storage box 71, a pressure plate 72 and a connecting rod 73. The liquid storage box 71 has a box cavity for storing nutrient solution. The liquid storage box 71 includes a side plate 711, a top plate and a bottom plate. The top plate is fixedly connected to the lower side of the cover body. A plurality of first liquid outlet holes 713 are provided on the bottom plate. A second liquid inlet hole is provided on the side plate 711. The end of the liquid inlet pipe passes through the first liquid inlet hole 12 and the second liquid inlet hole and extends into the liquid storage box 71; the pressure plate 72 is movably arranged on the liquid storage box 71 in the up-and-down direction to drive the nutrient solution to be output downward from the first liquid outlet hole 713; the connecting rod 73 has an up-and-down movable stroke, and a through hole is provided on the cover body corresponding to the liquid storage box 71. One end of the connecting rod 73 is fixedly connected to the pressure plate 72, and the other end extends out of the cover body from the through hole. With such arrangement, the nutrient solution can be injected into the liquid storage box 71 through the liquid inlet tube, and then the nutrient solution flows evenly into the storage barrel 1 from the plurality of first liquid outlet holes 713 to mix with the water in the storage barrel 1, thereby improving the uniformity of the mixing of the nutrient solution and water.

[0073] It should be noted that the pressing plate 72 is sealed with the side plate 711 during the process of moving up and down, and a third elastic member is fixedly connected between the top surface of the pressing plate 72 and the top plate of the liquid storage box 71. When the nutrient solution is added to the liquid storage box 71 or the connecting rod 73 is manually lifted up, the pressing plate 72 will compress the third elastic member while moving upward. When the nutrient solution is released, the pressing plate 72 will allow the liquid to be sprayed out from the first liquid outlet 713 with a greater pressure under the rebound force of the third elastic member, so that the nutrient solution is diffused more widely in the water body, thereby improving the mixing efficiency of the nutrient solution and water. When the pressing plate 72 needs to be reset, the connecting rod 73 can be lifted upward so that the connecting rod 73 drives the pressing plate 72 to reset. Among them, the third elastic member can be set as a spring.

[0074] Further, the bottom plate includes a first bottom plate 712 and a second bottom plate 714 arranged vertically, and the first bottom plate 712, the second bottom plate 714 and the side plate 711 enclose a discharge cavity; the liquid storage assembly 7 also includes a liquid control plate 74, which is horizontally slidably arranged in the discharge cavity, and the thickness of the liquid control plate 74 is adapted to the height of the discharge cavity, so that the sealing performance between the liquid control plate 74 and the first bottom plate 712 and the second bottom plate 714 is good in the liquid storage state, and the liquid control plate 74 is provided with a plurality of second liquid outlet holes 741 corresponding to the first liquid outlet hole 713. During its activity, the liquid control plate 74 has a liquid discharge state in which the second liquid outlet hole 741 is connected to the first liquid outlet hole 713 in the vertical direction, and a liquid storage state in which the second liquid outlet hole 741 is staggered from the first liquid outlet hole 713 in the vertical direction. In this way, by controlling the sliding of the liquid control plate 74, it is controlled whether the liquid in the liquid storage box 71 flows into the storage barrel 1. When the liquid storage box 71 does not need to release the nutrient solution into the storage barrel 1, the liquid control plate 74 is in the initial state, and the second liquid outlet hole 741 and the first liquid outlet hole 713 are staggered in the vertical direction; when the liquid storage box 71 needs to release the nutrient solution into the storage barrel 1, the liquid control plate 74 moves to the liquid outlet state, and the second liquid outlet hole 741 and the first liquid outlet hole 713 are connected in the vertical direction to realize the release of the nutrient solution into the storage barrel 1. It can be understood that the liquid control plate 74 is sealed between the first bottom plate 712 and the second bottom plate 714 in the liquid outlet state.

[0075] In some embodiments, the movement of the liquid control plate 74 is achieved by a sliding assembly. In some other embodiments of the present application, a second magnetic member 75 is provided at one end of the liquid control plate 74; the liquid storage assembly 7 further includes a second magnetic block 76, a connecting rod structure 77 and a second elastic member 78: the second magnetic block 76 repels the second magnetic member 75, the second magnetic block 76 is arranged in the inner cavity 11 of the storage barrel 1, and is arranged in the horizontal direction corresponding to the liquid control plate 74; the connecting rod structure 77 is fixedly connected to the second magnetic block 76 and the rotating shaft 41, so that the The second magnetic block 76 rotates with the rotating shaft 41; the two ends of the second elastic member 78 are respectively connected to the liquid control plate 74 and the side plate 711 of the liquid storage box 71; wherein, when the second magnetic block 76 rotates to be close to the second magnetic member 75, the second magnetic member 75 is pushed to move in a direction away from the second magnetic block 76 until the liquid control plate 74 is in a liquid discharge state; when the second magnetic block 76 rotates to be away from the second magnetic member 75, the second elastic member 78 pushes the liquid control plate 74 to reset until the liquid control plate 74 is in a liquid storage state. In this arrangement, the magnetic force between the second magnetic block 76 and the second elastic member 78 is used as the driving force of the liquid control plate 74, and the movement and reset of the liquid control plate 74 can be achieved without other power devices or matching components. wherein, the second elastic member 78 can be set as a spring.

[0076] In some other embodiments, the second magnetic block 76 and the second magnetic member 75 can be configured to be magnetically attracted to each other. When the second magnetic block 76 rotates to be close to the second magnetic member 75 and the liquid control plate 74 is in a liquid storage state, the second elastic member 78 is compressed. When the second magnetic block 76 rotates to be away from the second magnetic member 75, the second elastic member 78 is reset to push the liquid control plate 74 to move, so that the liquid control plate 74 is in a liquid discharge state.

[0077] Further, in some embodiments, please refer to Figure 6The liquid storage component 7 also includes a second monitoring structure 8, which includes a flexible ring 81 and a fixed ring 82. The flexible ring 81 is fixed on the top of the cover body and is used for the connecting rod 73 to movably pass through; the fixed ring 82 is arranged on the top of the flexible ring 81 and is fixedly arranged around the connecting rod 73; wherein, the flexible ring 81 is a hollow structure, and a plurality of air holes are opened on the outer wall of the flexible ring 81, the air holes are closed when the flexible ring 81 is in a natural state, and are opened when the flexible ring 81 is deformed by external force, and the flexible ring 81 is filled with colored gas to release the colored gas for early warning when the fixed ring 82 compresses the flexible ring 81. When the liquid in the liquid storage box 71 decreases, the pressure plate 72 will drive the connecting rod 73 to move downward. When the nutrient solution is used up or the remaining amount is small, the fixed ring 82 on the connecting rod 73 will squeeze the flexible ring 81 so that the pores are stretched open. At this time, red gas will be discharged from the flexible ring 81 to warn the staff that the nutrient solution in the liquid storage box 71 is insufficient.

[0078] In one embodiment of the present application, the nutrient solution can be injected into the liquid storage box 71 through the liquid inlet pipe, and then flow evenly into the storage barrel 1 from the first liquid outlet hole 713 and the second liquid outlet hole 741, and mix with the water in the water storage to obtain the nutrient solution, which can improve the uniformity of the mixing of the nutrient solution and water; the first liquid outlet hole 713 can also be sealed with the help of the liquid control plate 74, and then the nutrient solution is injected into the liquid storage box 71 for storage; when the nutrient solution needs to be used, the rotating shaft 41 can be driven to rotate, so that the second magnetic block 76 is away from the end of the liquid control plate 74 where the first magnetic part is provided, so that the first liquid outlet hole 713 is aligned with the second liquid outlet hole 741. At this time, the nutrient solution will fall from the first liquid outlet hole 713 and the second liquid outlet hole 741 into the storage barrel 1, so that the nutrient solution can be stored for use at any time.

[0079] When water and nutrient solution are added to the storage barrel 1, the motor can be started to drive the rotating shaft 41 to rotate. At this time, the blades 42 will stir and mix the water and nutrient solution in the storage barrel 1 to enhance the effect of irrigating the planting area. In this process, the nutrient solution in the storage barrel 1 will enter the rotating shaft 41 from the water outlet 412, and enter the mixing member 51 through the mixing hole 514. During the movement of the barrier 52, the nutrient solution in the mixing member 51 will flow out of the rotating shaft 41 cavity 411 from the mixing hole 514 and the water outlet 412, thereby improving the mixing efficiency between water and nutrient solution.

[0080] By distributing the branch pipes 22 on the planting ground where plants are planted, and inserting the conical temperature and humidity sensor 3 into the ground, and then injecting water and nutrient solution into the storage barrel 1, when the temperature and humidity sensor 3 senses that the ground is too dry, the water pump 23 and the solenoid valve are started. At this time, the water in the storage barrel 1 will enter the mainstream pipe 21, and then enter the branch pipe 22, and finally drip from the irrigation hole 221 on the branch pipe 22 to the planting ground, so that the humidity of the planting ground increases. When the temperature and humidity sensor 3 senses that the humidity has reached an appropriate value, the solenoid valve on the corresponding branch pipe 22 can be closed to prevent water from entering the planting ground in this area. When the values ​​sensed by all temperature and humidity sensors 3 meet the requirements, the water pump 23 and the solenoid valve on the mainstream pipe 21 will be closed. The above mechanism can achieve the effect of automatic drip irrigation of the plant planting ground. At the same time, the automatic opening and closing of the branch pipe 22 can be controlled according to the humidity of the planting ground to achieve the effect of saving water.
