[0004] However, the device still has the following problems: when spraying and irrigating plants, it cannot adapt to crops with different plant spacing, and cannot spray water or pesticides according to the plant spacing, so its adaptability is small; and it cannot adapt to planting areas of different widths. If the area is too wide, it is easy to cause incomplete spraying, and if the area is too narrow, it is easy to cause waste of spraying water. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, a water conservancy irrigation device is provided to address the problems mentioned in the above technical background.

[0006] The technical solution adopted by this utility model to solve its technical problem is: This utility model proposes a water conservancy irrigation device, including a frame on which a water tank is placed. A water supply pipe connected to the water tank is fixedly connected to the frame. Several spray pipes are fixed on the water supply pipe. A sealing element capable of sealing the spray pipe is provided inside the spray pipe. It also includes a spray head detachably connected to the spray pipe. When the spray head is connected to the spray pipe, it can drive the sealing element to open the spray pipe, so that the liquid in the water supply pipe can be sprayed through the spray head.

[0007] Preferably, the sealing element is a sealing ball, the spray pipe has an opening, and the sealing ball is connected to the water supply pipe by a spring. The spring force can drive the sealing ball to seal the opening of the spray pipe.

[0008] Preferably, a push rod is fixed inside the spray head. When the spray head is connected to the spray pipe, the push rod can drive the spring to compress, causing the sealing ball to move away from the opening of the spray pipe, thereby opening the opening of the spray pipe.

[0009] Preferably, the spray pipe has a spray chamber, and the sealing ball is located in the spray chamber. When the sealing ball is located in different positions in the spray chamber, the flow rate of the spray head can be adjusted.

[0010] Preferably, the spraying chamber is V-shaped.

[0011] Preferably, a limiting rod is rotatably connected to one side of the spray head. The limiting rod is connected to the spray head via a compression spring. A limiting groove is provided on the spray pipe for the limiting rod to slide freely into. The elastic force of the compression spring can drive the limiting rod to slide into the limiting groove, thereby locking the spray pipe and the spray head.

[0012] Preferably, the spray pipe has several limiting grooves along its axial direction that cooperate with the limiting rod.

[0013] Preferably, an extension pipe is slidably connected to one side of the water supply pipe, and several spray pipes are fixed on the extension pipe. The extension pipe is connected to the water tank or the water supply pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with several detachably connected spray pipes and spray heads. The spray pipes are connected to the water tank. When no spray head is installed on the spray pipe, the spray pipe remains closed. By installing spray heads on the spray pipes at different positions, the spray pipe at that position is opened and sprayed through the spray head. This can well adapt to the row spacing of crops or plants, allowing the spray water flow to accurately cover the core absorption area of ​​each crop, thereby improving the efficiency of water resource utilization.

[0017] 2. This utility model is equipped with an extension pipe, on which several spray pipes are also installed. When encountering a wide plot of land, the extension pipe can slide out from one side of the water supply pipe. Then, according to the spacing between plants, the number of spray heads on the extension pipe can be increased or decreased, thereby increasing the spray width and making it more adaptable to various plots.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Example 1 refer to Figures 1-6 This embodiment proposes a water conservancy irrigation device, including a frame 1, a water tank 2 placed on the frame 1, a water supply pipe 3 connected to the water tank 2 and fixedly connected to the frame 1, a plurality of spray pipes 4 fixed on the water supply pipe 3, and a sealing component that can block the spray pipe is provided inside the spray pipe 4; it also includes a spray head 5 detachably connected to the spray pipe 4, when the spray head 5 is connected to the spray pipe 4, it can drive the sealing component to open the spray pipe 4, so that the liquid in the water supply pipe 3 can be sprayed through the spray head 5.

[0022] Specifically, the water supply pipe 3 is hollow inside. The water supply pipe 3 is fixed to the water tank or frame 1 by connecting buckles. Several water inlets that communicate with the outside are evenly opened in the axial direction of the water supply pipe 3. The spray pipe 4 is connected to the water inlet by welding or threading and is connected and fixed to the water supply pipe 3. The axial direction of the water supply pipe 3 is perpendicular to the travel direction of the frame 1.

[0023] Water tank 2 is connected to a water pump, and the water pump is connected to a water pump motor.

[0024] Specifically, a power supply is placed on the frame, which is directly connected to the water pump motor. The water pump motor is directly connected to a controller, and the controller has a display screen that can display the water pump power or flow rate.

[0025] Specifically, when irrigating the plot, according to the row spacing of the plants on the plot, spray heads 5 are installed on the spray pipes 4 at different positions so that the spray heads 5 correspond to the position of each row of plants. The spray head 5 at that position drives the sealing part to open the spray pipe 4, and the liquid in the water tank 2 flows through the water supply pipe 3 and the spray pipe 4 and is sprayed out through the spray head 5.

[0026] Specifically, when the plant spacing is fixed, the root system of each crop will extend in a specific area. If the spray head spacing matches the plant spacing, the sprayed water flow can accurately cover the core absorption area of ​​the root system of each crop, avoiding the water flow from concentrating in the gaps between plants or missing some plants and causing local drought.

[0027] The sealing component is a sealing ball 6. The spray pipe 4 has an opening. The sealing ball 6 is connected to the water supply pipe 3 through a spring 7. The elastic force of the spring 7 can drive the sealing ball 6 to seal the opening of the spray pipe 4.

[0028] A push rod 8 is fixed inside the spray head 5. When the spray head 5 is connected to the spray pipe 4, the push rod 8 can drive the spring 7 to compress, so that the sealing ball 6 moves away from the opening of the spray pipe 4, thereby opening the opening of the spray pipe 4.

[0029] A limiting rod 9 is rotatably connected to one side of the spray head 5. The limiting rod 9 is connected to the spray head 5 through a compression spring 10. A limiting groove 20 is provided on the spray pipe 4 for the limiting rod 9 to slide freely into. The elastic force of the compression spring 10 can drive the limiting rod 9 to slide into the limiting groove, thereby locking the spray pipe 4 and the spray head 5.

[0030] Specifically, the limit rod 9 is rotatably connected to one side of the spray head 5. When disassembling the spray head 5, it can be disassembled with just one hand, which is convenient and quick.

[0031] Along the axial direction of the spray pipe 4, there are several limiting grooves 20 that cooperate with the limiting rod 9.

[0032] Specifically, the spray head 5 can be fitted onto the outside of the spray pipe 4. When the spray pipe 4 slides into the spray head 5, the push rod 8 inside the spray head 5 will pass through the opening of the spray pipe 4 and contact the sealing ball 6. As the spray head 5 continues to be installed, the push rod 8 will push the sealing ball 6 open a certain distance, opening the opening and supplying water to the inside of the spray head 5, so that the spray head 5 can spray.

[0033] Specifically, a sealing ring 18 is placed inside the spray head 5 to seal the spray pipe 4 and the spray head 5 and prevent water leakage.

[0034] Example 2 Since different plants have different water requirements during spraying, it is necessary to match the water supply to each plant. Based on Example 1, the spray pipe 4 is further modified.

[0035] The spray pipe 4 has a spray chamber 11, and the sealing ball 6 is located in the spray chamber 11. When the sealing ball 6 is located in different positions in the spray chamber 11, the flow rate of the spray head 5 can be adjusted.

[0036] The spray chamber 11 is V-shaped.

[0037] Specifically, when the blocking ball 6 is located at the bottom of the "V" shape of the spray chamber 11, the spring 7 can drive the blocking ball 6 to block the spray chamber. Since the cross-sectional area of ​​the blocking ball 6 remains unchanged, when the water supply pressure is constant, the higher the position of the blocking ball 6, the greater the distance between the blocking ball 6 and the spray chamber 11, which is equivalent to increasing the cross-sectional area of ​​the water flow. Therefore, more water can flow out per unit time. Conversely, the lower the position of the blocking ball 6, the less water flow per unit time, which can adapt to plants with different water requirements.

[0038] Example 3 Since the width of various plots is different during spraying, it is necessary to adapt to planting areas of different widths. Based on Example 1 or Example 2, the water supply pipe 3 is further modified.

[0039] An extension pipe 12 is slidably connected to one side of the water supply pipe 3. Several spray pipes 4 are fixed on the extension pipe 12. The extension pipe 12 is connected to the water tank 2 or the water supply pipe 3.

[0040] A sliding plate 13 is fixed on the water supply pipe 3. A sliding groove 14 is provided on the sliding plate 13. At least two screws 15 are fixedly connected to the extension pipe 12. The screws 15 are slidably arranged in the sliding groove. After the screws 15 pass through the sliding groove, they are threadedly connected to a nut 16.

[0041] Specifically, the extension pipe 12 is connected to the water tank 2 or the water supply pipe 3 via the flexible hose 19.

[0042] Specifically, when encountering a wider plot, first loosen the nut 16 so that the extension pipe 12 can slide relative to the sliding plate 13 via the screw 15. After sliding to a suitable position corresponding to the width of the plot, tighten the nut 16 to fix the position of the extension pipe. Then, according to the row spacing of the plants, install an appropriate number of spray heads 5 on the extension pipe 12.

[0043] Specifically, when the plot is narrow and the plants require less water, a sprinkler head 5 can be installed on the water supply pipe 3 to provide a small amount of water. When the plants require more water, a sprinkler head can be installed on the extension pipe 12 located behind the water supply pipe 3 to provide a larger amount of water and further increase the water supply. Detailed implementation method: First, fill the water tank with water. Then, according to the row spacing of the plants, install the spray head 5 on the appropriate position of the spray pipe 4 on the water supply pipe 3, start the water pump 17, and start water supply. By manpower or power machinery, the frame 1 is moved forward, and the water flow is sprayed on the plants in the corresponding positions through the spray head 5 to irrigate the plants.

[0045] When the plot is narrow and the water demand is low, simply install a sprinkler head on the sprinkler pipe 4 on the water supply pipe 3, and then adjust the height of the sprinkler head 5 on the sprinkler pipe 4 according to the water demand of the plants being irrigated, so as to achieve different water output from the sprinkler head 5. When the plot is narrow and the water demand is high, an appropriate number of sprinkler heads 5 can be installed on the extension pipe 12 behind the water supply pipe 3 to increase the water supply. When the plot is wide, loosen the nut 16 so that the extension pipe 12 slides out from behind the water supply pipe 3. After sliding out a suitable length, tighten the nut 16 to re-fix the extension pipe 12. Then, depending on the plant conditions, install an appropriate number of spray heads 5 on the extension pipe 12 for spraying.
