[0002] Greening refers to the planting of shelterbelts, roadside trees, crops, and various plants in residential areas and parks. Greening can improve the environment and play a variety of roles in maintaining ecological balance. Greening plants need a suitable environment and sufficient nutrition to grow. Greening irrigation provides water for greening plants, and there are nutrients in the water to meet the growth needs of greening plants.

[0003] In the prior art, water is applied to plants by using tools such as water sprinklers, water pipes, and watering cans, and the sprinklers are used for atomization to expand the contact area between green plants and water.

[0004] However, when the watering device is watering, the water volume is fixed, and the water volume required by the plants is related to the local climate conditions, that is, the higher the temperature, the higher the water volume required by the plants, and the water volume will not meet the needs of the plants. Utility Model Content

[0005] The utility model aims to provide a greening watering device to solve the problem in the background technology that the amount of water for watering cannot meet the needs of plants.

[0006] The technical solution of the utility model: a greening watering device, comprising:

[0007] An irrigation pipe, wherein the pipe body of the irrigation pipe is connected to a plurality of equally spaced irrigation nozzles, and the end of the irrigation pipe is connected to a nutrient solution tank and a water tank;

[0008] The mixing assembly includes a mixing cylinder, a spiral water guide groove, a nutrient solution pipe and a water pump. The inner wall of the mixing cylinder is provided with a spiral water guide groove. The end of the mixing cylinder is connected to the water pump. The middle of the mixing cylinder is connected to the nutrient solution pipe. The nutrient solution pipe is connected to the nutrient solution tank. The water pump is connected to the water tank through a pipeline.

[0009] The water pump is electrically connected to a humidity sensor, which is buried underground. Green plants are distributed on both sides of the irrigation pipe, and a protective component is arranged on the surface of the humidity sensor.

[0010] Optionally, the end of the mixing barrel adopts a truncated cone structure, the nutrient solution tube is located at the spiral water guide groove of the mixing barrel, and a one-way valve is fixedly installed on the nutrient solution tube.

[0011] Optionally, the end of the water pump is connected to a guide water pipe, the guide water pipe penetrates into the interior of the mixing barrel, the guide water pipe adopts an L-shaped structure, and the part of the guide water pipe entering the mixing barrel is close to the spiral water guide groove.

[0012] Optionally, water flows in the guide water pipe, nutrient solution flows in the nutrient solution pipe, the water enters the mixing barrel and flows spirally along the spiral water guide groove, and the nutrient solution is located on the path of the spiral flow of water.

[0013] Optionally, the protection component includes a protective shell and an electric push rod, the electric push rod is fixedly installed on the inner wall of the protective shell, the humidity sensor is fixedly installed on the end of the electric push rod, the protective shell is buried underground, a test cavity is opened under the protective shell, and the humidity sensor is located in the test cavity.

[0018] The utility model detects soil moisture through a humidity sensor and adjusts the pumping speed of a water pump according to the humidity. The pumping speed per unit time is increased, and the watering amount for green plants is adjusted according to the environment. Water and nutrient solution are stored separately. During watering, the speed of water changes while the speed of nutrient solution remains unchanged, thereby avoiding pre-mixing of nutrient solution and water. When the water required by green plants increases, the nutrient solution for watering green plants also increases, causing root rot of green plants.

[0019] Furthermore, the recycled water enters the mixing barrel and flows in a spiral flow. The nutrient solution flowing in the nutrient solution pipe is preliminarily mixed by the impact of water on the path of the spiral flow of water. The rotational force generated by the spiral flow is then used to rotate the water and nutrient solution at the end of the mixing barrel and mix them again, making the mixing more uniform.

[0020] Furthermore, during the test, the electric push rod extends to push the humidity sensor into the test cavity to test the soil humidity. When not testing, the humidity sensor is stored in the protective shell to prevent the humidity sensor from being in the underground humid environment for a long time, which shortens its service life.

[0031] Example 1

[0032] This embodiment provides a greening watering device, such as Figure 1 As shown, it includes a watering pipe 1, the pipe body of the watering pipe 1 is connected to a plurality of equally spaced watering nozzles 2, and the end of the watering pipe 1 is connected to a nutrient solution tank 4 and a water tank 5;

[0033] like Figure 2 and 3 As shown, the mixing assembly 3 includes a mixing barrel 31, a spiral water guide groove 32, a nutrient solution pipe 34 and a water pump 36. The inner wall of the mixing barrel 31 is provided with a spiral water guide groove 32. The end of the mixing barrel 31 is connected to the water pump 36. The middle of the mixing barrel 31 is connected to the nutrient solution pipe 34. The nutrient solution pipe 34 is connected to the nutrient solution tank 4. The water pump 36 is connected to the water tank 5 through a pipeline. The nutrient solution pipe 34 delivers the nutrient solution at a constant speed, and the water pump 36 extracts water from the water tank 5.

[0034] like Figure 2 As shown, the end of the water pump 36 is connected to a guide water pipe 33, and water in the water tank 5 is pumped through the water pump 36. The water pump 36 is electrically connected to a humidity sensor 37 through a controller, and the humidity sensor 37 is buried underground. Green plants are distributed on both sides of the irrigation pipe 1.

[0035] The humidity sensor 37 detects the underground humidity, and increases the pumping speed of the water pump 36 according to the humidity, while the speed of the nutrient solution flowing in the nutrient solution pipe 34 remains unchanged. Different soil humidity will result in different amounts of water required by green plants, but it has nothing to do with the amount of nutrient solution. If the nutrient solution and water are mixed in advance before watering, the amount of water required by green plants will be too much, which will lead to excessive nutrient solution and cause root rot of green plants. Therefore, the nutrient solution should be separated from water, and the ratio should be controlled during watering.

[0036] The guide water pipe 33 penetrates into the mixing barrel 31. The guide water pipe 33 adopts an L-shaped structure. The portion of the guide water pipe 33 entering the mixing barrel 31 is close to the spiral water guide groove 32. The end of the mixing barrel 31 adopts a truncated cone structure. Water flows in the guide water pipe 33, and nutrient solution flows in the nutrient solution pipe 34. The water enters the mixing barrel 31 and flows in a spiral along the spiral water guide groove 32. The nutrient solution is located on the path of the water spiral flow.

[0037] like Figure 3 As shown, by the guide water pipe 33 being attached to the spiral water guide groove 32, the water entering the mixing barrel 31 is caused to flow in a spiral. During the flow, the water impacts the nutrient solution entering from the nutrient solution pipe 34 for preliminary mixing. The nutrient solution flows along with the water. When moving to the truncated cone structure at the end of the mixing barrel 31, the water and the nutrient solution rotate and are mixed again, so that the nutrient solution and water are mixed more evenly.

[0038] The nutrient solution pipe 34 is located at the spiral water guide groove 32 of the mixing barrel 31, and a one-way valve 35 is fixedly installed on the nutrient solution pipe 34. The one-way valve 35 prevents water and nutrient solution from flowing back into the nutrient solution tank 4.

[0039] In this embodiment, the soil humidity is detected by the humidity sensor 37, and the pumping speed of the water pump 36 is adjusted according to the humidity. The pumping speed per unit time is increased, while the speed of the nutrient solution remains unchanged, so that the ratio of the nutrient solution and water can be controlled during irrigation. The water enters the mixing barrel 31 and flows in a spiral. The nutrient solution flowing in the nutrient solution pipe 34 is preliminarily mixed by the impact of water on the nutrient solution on the path of the spiral flow of water. The rotational force generated by the spiral flow is used to rotate the water and nutrient solution at the end of the mixing barrel 31 and mix them again to make the mixing more uniform.

[0040] Example 2

[0041] Based on Example 1, this embodiment proposes a greening watering device, such as Figure 4 As shown, a protection component 6 is provided on the surface of the humidity sensor 37, and the protection component 6 includes a protection shell 61 and an electric push rod 63. The electric push rod 63 is fixedly installed on the inner wall of the protection shell 61, and the humidity sensor 37 is fixedly installed on the end of the electric push rod 63. The protection shell 61 is buried underground, and a test cavity is opened below the protection shell 61, and the humidity sensor 37 is located in the test cavity.

[0042] The position of the humidity sensor 37 is changed by extending and retracting the electric push rod 63, so that the humidity sensor 37 enters the test cavity to detect the soil humidity during detection. When not detecting, the humidity sensor 37 is stored in the protective shell 61 to prevent the humidity sensor 37 from being in a humid environment for a long time, which shortens its service life. An exhaust hole is provided on the top of the protective shell 61 to discharge the moisture in the soil that enters the protective shell 61. The electric push rod 63 is extended periodically to periodically detect the soil moisture.

[0043] like Figure 4As shown, an inlet and outlet are provided at the bottom of the protective shell 61, and a sealing plate 64 is rotatably connected to the inlet and outlet of the protective shell 61 via a rotating shaft, and the rotating shaft of the sealing plate 64 is elastically connected to the protective shell 61 via a torque spring 65. The shape of the sealing plate 64 is the same as the shape of the inlet and outlet of the protective shell 61, and a sealing rubber is fixedly installed on the side of the sealing plate 64.

[0044] When the humidity sensor 37 enters the protective shell 61, the humidity sensor 37 squeezes the sealing plate 64 to rotate and fully open the entrance and exit. At the same time, the sealing plate 64 rotates to compress the torque spring 65. When the humidity sensor 37 completely enters the protective shell 61, the elastic force of the torque spring 65 resets the sealing plate 64, so that the sealing plate 64 closes the entrance and exit to prevent moisture from entering the protective shell 61. The sealing rubber on the side of the sealing plate 64 increases the sealing effect.

[0045] like Figure 4 As shown, a protective plate 62 is fixedly installed between the humidity sensor 37 and the electric push rod 63. The protective plate 62 is L-shaped and contacts the sealing plate 64. The protective plate 62 prevents the humidity sensor 37 from directly contacting the sealing plate 64 to protect the humidity sensor 37.

[0046] In this embodiment, during detection, the electric push rod 63 extends to push the humidity sensor 37 into the test cavity to detect soil humidity. When not detecting, the humidity sensor 37 is stored in the protective shell 61 to prevent the humidity sensor 37 from being in a humid underground environment for a long time, which shortens its service life.

[0047] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
