[0002] Plants account for a relatively large proportion of the garden landscape. In the daily maintenance of plant landscape, they often need to be irrigated and sprayed. There are two common spraying methods. One is to use preset nozzles to irrigate plants and complete the irrigation and spraying of plants through regular water supply. The other is for gardeners to irrigate using tools such as irrigation vehicles.

[0003] The patent document with the patent publication number CN119344192A discloses a garden plant irrigation device, including a water tank, an installation box, a lifting mechanism, a first drive assembly, a second drive assembly, a support mechanism and a plurality of spraying mechanisms, wherein the installation box is fixedly arranged on the water tank, and a partition is arranged inside the installation box; the lifting mechanism is vertically and rotatably arranged on the partition, and the top end of the lifting mechanism passes through the installation box, and the bottom end of the lifting mechanism is rotatably connected to the output end of the pump body arranged in the water tank; the first drive assembly is arranged in the installation box, and the first drive assembly is connected to the lifting mechanism; the second drive assembly is arranged in the installation box, and the second drive assembly is connected to the lifting mechanism; the support mechanism is arranged on the top wall of the installation box.

[0004] However, the existing irrigation devices have a small spraying range and are difficult to adjust, which easily leads to the fertilizer and water being sprayed only in certain areas, causing poor growth in the edge areas of plants due to insufficient nutrition or water. In addition, most of the existing water-fertilizer integrated irrigation devices mix fertilizer with water in advance, and then spray fertilizer water directly on the plants. In actual use, different plants require different amounts of fertilizer. It is difficult for traditional water-fertilizer integrated irrigation devices to adjust the amount of fertilizer to be applied according to the actual needs of users. Summary of the invention

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] like Figure 1-Figure 2 As shown, a water-fertilizer integrated water-saving irrigation device for garden plants comprises: A support base 1 is provided with a water tank 2 and a fertilizer storage tank 3; the support base 1 is the basic component of the entire irrigation device, and plays the role of supporting and fixing other components. Usually, the support base 1 is made of weather-resistant and corrosion-resistant materials (such as stainless steel, plastic, etc.) to ensure that the equipment will not be damaged during long-term use in outdoor environments. A water tank 2 and a fertilizer storage tank 3 are provided on the base to store water and fertilizer respectively, so as to ensure the timely supply of water and fertilizer.

[0027] In order to prevent the water source from being polluted, a filtering system is usually added to the design of the water storage tank 2 to avoid deterioration of water quality. A water inlet pipe 41 is provided at the upper end of the water tank for connecting to a water supply pipeline to ensure the input of water source.

[0028] The fertilizer storage box 3 is a container for storing fertilizer, which is usually a closed box to prevent the fertilizer from getting damp or contaminated. The fertilizer storage box 3 is connected to the spraying mechanism 4 through a fertilizer connecting pipe 31. When the plants need to be fertilized, the fertilizer can be transported to the spraying mechanism 4 through the connecting pipe to ensure uniform supply of water and fertilizer.

[0029] A spraying mechanism 4 is disposed at the upper end of the water storage tank 2, and the spraying mechanism 4 is also connected to the fertilizer storage tank 3 through a fertilizer connecting pipe 31; the spraying mechanism 4 is used to spray water and fertilizer onto the plants in a certain proportion and manner.

[0030] The spray mechanism 4 includes a water inlet pipe 41 connected to the water storage tank 2, a three-way valve unit 42 connected to the water inlet pipe 41, a first spray assembly 43 and a second spray assembly 44 arranged on both sides of the three-way valve unit 42, a first spray water pipe 45 arranged outside the first spray assembly 43, and a second spray water pipe 46 arranged outside the second spray assembly 44; The water inlet pipe 41 connects the water storage tank 2 and the spraying mechanism 4 and is an input pipe for water flow; The three-way valve unit 42 is located between the water inlet pipe 41 and the spray assembly, and is used to adjust the direction of the water flow; the three-way valve unit 42 controls the switch of the water flow through the valve, and can distribute the water flow to the first spray assembly 43 or the second spray assembly 44 as needed; The first spray assembly 43 and the second spray assembly 44 are the main spray head parts in the device, which are responsible for delivering water and fertilizer to the first spray water pipe 45 or the second spray water pipe 46; The first spraying water pipe 45 and the second spraying water pipe 46 are connected to the first spraying assembly 43 and the second spraying assembly 44 respectively, and are used to transfer water or fertilizer from the spraying assembly to the soil around the plants.

[0031] The upper end of the water storage tank 2 is provided with a first driving mechanism 5 for driving the water inlet pipe 41 to rotate, and the first spraying assembly 43 and the second spraying assembly 44 are respectively provided with a second driving mechanism 6 for driving the first spraying water pipe 45 or the second spraying water pipe 46 to rotate; The first driving mechanism 5 is installed at the upper end of the water storage tank 2, and is used to drive the rotation of the water inlet pipe 41, so that the water flow can rotate to different directions along the horizontal plane as needed. This design can flexibly adjust the flow direction of the water flow according to different irrigation needs; The second driving mechanism 6 is responsible for rotating the first spraying water pipe 45 or the second spraying water pipe 46. By driving the water pipe to rotate, the spraying angle and range of the water flow can be changed, thereby achieving more uniform irrigation.

[0032] Another major feature of the device is the precise mixing and supply of water and fertilizer. Through the fertilizer connecting pipe 31, the fertilizer in the fertilizer storage box 3 can be automatically mixed with the water source according to the set ratio and needs, and accurately delivered to the plants through the spraying mechanism 4. Since water and fertilizer are supplied synchronously, the plants can fully absorb nutrients, while avoiding fertilizer waste and saving resources.

[0033] Further, if Figure 2-Figure 4As shown, the first driving mechanism 5 includes a first driving unit 51 fixedly arranged at the upper end of the water storage tank 2, a first bevel gear 52 drivingly connected to the first driving unit 51, and a second bevel gear 53 drivingly connected to the first bevel gear 52 and fixedly connected to the water inlet pipe 41; The second driving mechanism 6 includes a second driving unit 61 fixedly arranged on the outside of the first spraying assembly 43 or the second spraying assembly 44, a first gear 62 transmission connected to the second driving unit 61, and a second gear 63 transmission connected to the first gear 62 and fixedly connected to the first spraying water pipe 45 or the second spraying water pipe 46.

[0034] The main function of the first driving mechanism 5 is to provide power through the first driving unit 51, transmit it to the second bevel gear 53 through the first bevel gear 52, and then control the rotation of the water inlet pipe 41 through the second bevel gear 53, thereby changing the spraying range of the first spraying water pipe 45 and the second spraying water pipe 46.

[0035] The second driving mechanism 6 is powered by the second driving unit 61, which drives the second gear 63 to rotate through the first gear 62, and then transmits the power to the first spraying water pipe 45 and the second spraying water pipe 46, so as to change the spraying angle and range of the water flow.

[0036] The core function of this system is to accurately distribute the power of the drive unit to different components through the gear transmission mechanism to achieve different ranges of liquid spraying.

[0037] The first driving unit 51 and the second driving unit 61 may be electric motors, hydraulic driving units or other types of power sources for driving the rotation of the spraying device.

[0038] Further, if Figure 2 As shown, a fertilizer delivery pump 7 is also provided at the upper end of the water storage tank 2, one end of the fertilizer delivery pump 7 is connected to the fertilizer storage tank 3, and the other end is connected to the fertilizer feeding mechanism 8 arranged at the upper end of the spraying mechanism 4 through a fertilizer connecting pipe 31.

[0039] The fertilizer delivery pump 7 is a power device, and its function is to suck the fertilizer from the fertilizer storage box 3 and deliver it to the spraying system when the system is working. The input end is connected to the fertilizer storage box 3 for receiving the original fertilizer liquid, and the output end is connected to the fertilizer feeding mechanism 8 through a fertilizer connecting pipe 31 to realize the quantitative transmission of the fertilizer liquid.

[0040] Further, if Figure 5-Figure 7As shown, the fertilizer feeding mechanism 8 includes a feeding box 81 arranged at the upper end of the three-way valve unit 42, a first valve body 82 and a second valve body 83 arranged inside the feeding box 81, a first fertilizer pipe 84 connected to the first valve body 82 and extending into the three-way valve unit 42, and a second fertilizer pipe 85 connected to the second valve body 83 and extending into the three-way valve unit 42.

[0041] The first fertilizer pipe 84 is connected to the first spraying assembly 43 , and the second fertilizer pipe 85 is connected to the second spraying assembly 44 .

[0042] The first spraying assembly 43 and the second spraying assembly 44 receive fertilizers through corresponding fertilizer pipelines to achieve multi-path independent spraying control.

[0043] The fertilizer feeding mechanism 8 is used to realize the diversion and control supply of fertilizer, ensuring that the fertilizer can enter different spraying paths according to demand. Its core components include: The feeding box 81 is installed at the upper end of the three-way valve unit 42 and is a closed cavity structure, in which a fertilizer flow channel and control components are arranged; The first valve body 82 and the second valve body 83 are installed inside the feeding box 81, and play the role of controlling the circulation and closing of the fertilizer. They are key components for controlling whether the first spraying channel and the second spraying channel are opened or not; A first fertilizer pipe 84, one end of which is connected to the first valve body 82, and the other end of which extends into the interior of the three-way valve unit 42 and communicates with the first spraying assembly 43 to realize the fertilizer supply of the first path; The second fertilizer pipe 85 has a similar structure to the first fertilizer pipe 84 , is connected to the second valve body 83 and leads to the second spraying assembly 44 , forming a second fertilizer supply path.

[0044] The three-way valve unit 42 is installed at the core node of the spraying system, and is responsible for receiving the fertilizer delivered by the feeding mechanism and diverting it to the corresponding spraying components.

[0045] After the system is started, the fertilizer delivery pump 7 extracts fertilizer liquid from the fertilizer storage box 3 and delivers it to the feeding box 81 through the fertilizer connecting pipe 31. Inside the feeding box 81: The first valve body 82 and the second valve body 83 perform a switching action according to a control system (which may be solenoid valve control or mechanical switch control); If the first valve body 82 is opened, the fertilizer liquid flows into the three-way valve unit 42 through the first fertilizer pipe 84, and then is directed by the three-way valve unit 42 to the first spraying assembly 43 for spraying; If the second valve body 83 is opened, the fertilizer liquid is supplied to the second spraying assembly 44 through the second fertilizer pipe 85 instead; Either valve body can be opened individually to realize single-channel fertilizer spraying, or both valves can be opened at the same time to realize dual-channel spraying, which is suitable for different agronomic needs, such as precision fertilization or differential fertilization.

[0046] Further, if Figure 6-Figure 7 As shown, the first spray assembly 43 includes an outer sleeve 431 fixedly connected to the three-way valve unit 42 and a spiral conveying pipe 432 arranged inside the outer sleeve 431, the first spray water pipe 45 is connected to the spiral conveying pipe 432, and the second spray assembly 44 has the same structure as the first spray assembly 43.

[0047] The first spraying assembly 43 includes an outer sleeve 431 fixedly connected to the three-way valve unit 42. The outer sleeve 431 is a hollow structure, and its main function is to serve as a structural support and channel guiding element. A spiral conveying pipe 432 is coaxially arranged inside the outer sleeve 431. The conveying pipe adopts a spiral structure design, which can effectively realize the uniform propulsion and delivery of liquid fertilizer or mixed liquid. The structure helps to prevent the deposition and blockage of solid particles in the spraying liquid through the spiral flow mode, thereby improving the spraying efficiency and uniformity. Another beneficial effect of the spiral structure design of the delivery pipe is to ensure that the water flow and fertilizer stay in the first spray assembly 43 or the second spray assembly 44 for a sufficiently long time, thereby ensuring that the water and fertilizer are fully mixed and ensuring the uniform effect of the fertilizer water.

[0048] Further, if Figure 1 As shown, a protective cover 9 is also provided at the upper end of the water storage tank 2 , the first driving mechanism 5 and the second driving mechanism 6 are both arranged inside the protective cover 9 , and the fertilizer delivery pump 7 is also arranged inside the protective cover 9 .

[0049] An integrated protective cover 9 is installed at the upper end of the water tank 2, and the protective cover 9 is used to prevent external dust, debris, water vapor, etc. from entering the internal device, thereby protecting the operating safety and life of the internal electrical control and mechanical components.

[0050] Further, if Figure 1 As shown, the support base 1 is arranged on a trolley mechanism 10 , and a control panel 11 is arranged on the trolley mechanism 10 .

[0051] In order to realize convenient equipment movement and operation, a supporting base 1 is provided at the bottom of the overall device. The base has a stable structure and is connected to a cart mechanism 10 provided with a wheeled or crawler walking unit. The cart mechanism 10 is not only convenient for manual or electric driving of the mobile device, but also has a control panel 11 on its surface. The control panel 11 integrates a display screen, buttons, knobs or touch interface. Users can use the control panel 11 to adjust and monitor parameters such as spraying mode, spraying intensity, start and stop of the delivery pump, and drive mechanism action in real time.

[0052] Working process: Preparation The external water supply system supplies water to the water storage tank 2 through the water inlet pipe 41, and the user adds the fertilizer of the required type and ratio into the fertilizer storage tank 3; Start-up phase The user sets the irrigation parameters through the control panel 11 on the cart mechanism 10, such as: spraying path (selecting the first spraying assembly 43, the second spraying assembly 44, or using both), water-fertilizer ratio, spraying angle and rotation range, irrigation time or cycle; Fertilizer delivery and mixing stage The fertilizer delivery pump 7 is started, and liquid fertilizer is extracted from the fertilizer storage tank 3, and is delivered to the fertilizer delivery mechanism 8 through the fertilizer connection pipe 31. In the delivery mechanism, the control system opens one or both of the first valve body 82 and the second valve body 83, and the fertilizer is delivered to the first fertilizer pipe 84 or the second fertilizer pipe 85, respectively, and enters the corresponding spraying assembly. The fertilizer and water are fully mixed in the spiral delivery pipe 432 to form a uniform water-fertilizer mixture, ready for spraying; Spraying stage The first driving mechanism 5 is started, and the water inlet pipe 41 is rotated through the bevel gear system to adjust the overall spraying direction. The second driving mechanism 6 is started, and the first spraying pipe 45 or the second spraying pipe 46 is driven to rotate through the gears to further adjust the spraying angle and coverage. The water-fertilizer mixture is diverted through the three-way valve unit 42, and respectively passes through the first or second spraying assembly 44 and the spraying pipe, and is evenly sprayed on the plant roots or the surrounding soil area to achieve efficient irrigation. Stop and reset phase After reaching the set time or irrigation amount, the system automatically shuts down. If it is used in a mobile manner, the user can push the device to the next area through the cart mechanism 10.
