Technical Field
[0001] This utility model relates to the technical field of spraying devices, and in particular to an energy-saving spraying device for tree cultivation. Background Technology
[0002] Pine and poplar saplings require irrigation during cultivation. A Chinese utility model patent (publication number CN215530566U) discloses an energy-saving sprinkler device for sapling cultivation. This device includes a pressure-boosting valve connected to a water source, a main water pipe, and multiple branch water pipes connected to the main water pipe. Micro-sprinklers are connected to the branch water pipes. A vertically arranged support is attached to the trunk of the sapling, and the branch water pipes are bolted to the support. The micro-sprinklers are placed above the trees; the system supports the trees so that the sprinklers are positioned above them. Water is pressurized by a booster valve, flowing from the main water pipe to the distribution pipes. The micro-sprinklers on the distribution pipes then spray water onto the branches and leaves of the trees. Some of the sprayed water falls down to irrigate the roots of the trees, creating a mist spray effect that keeps the entire forest moist, ensuring that the roots and branches of the trees can fully absorb water.
[0003] The above-mentioned sprinkler system sprays water onto tree seedlings from top to bottom, so it requires a support frame to install water pipes and nozzles, making the setup quite complicated. Moreover, it can only spray the entire tree seedling, allowing water to fall along the seedling to irrigate the roots, resulting in a large amount of water evaporation when irrigating the roots. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an energy-saving spraying device for tree cultivation that can spray the entire tree seedling and irrigate the roots separately, is easy to set up, and is more energy-saving and water-saving.
[0005] This utility model discloses an energy-saving sprinkler system for tree cultivation, comprising a water pump and a water pipe, with the water pipe inlet connected to the water pump outlet; it also includes a sprinkler box, a connector, a nozzle holder, a vertical rod, a cover plate, and a water pressure assembly. The sprinkler box has an internal chamber, and a connector is installed on the sprinkler box, communicating with the chamber. The end of the water pipe is connected to the connector. The sprinkler box has an inclined surface, and the nozzle holder is vertically installed on the inclined surface of the sprinkler box, with multiple nozzles installed on the nozzle holder, which communicates with the chamber of the sprinkler box. The vertical rod is vertically mounted on the sprinkler box and can be raised and lowered. The water pressure assembly... Installed within the chamber of the sprinkler box, the water pressure assembly is connected to the vertical rod drive mechanism. Under the pressure of water within the sprinkler box chamber, the water pressure assembly drives the vertical rod to rise and fall. A cover plate is mounted on the vertical rod, parallel to the inclined surface of the sprinkler box, and positioned above the nozzle holders. During operation, multiple sprinkler boxes are connected in series via multiple water pipes. The sprinkler boxes are connected to a water pump via these pipes. Each sprinkler box is aligned with a specific sapling, and each sprinkler holder faces the sapling. Initially, the water pressure assembly lowers the vertical rod to its lowest position, the cover plate covers the nozzles of the sprinkler holders, and the water pump operates to flush the sprinkler. After being pressurized, the water is transported through pipes to the chambers of multiple spray boxes. As the water pressure in the chambers of the spray boxes gradually increases, the water pressure acts on the water pressure assembly, pushing the vertical rod and cover plate upwards, causing the cover plate to detach from the nozzle seat. When the water pressure in the chambers of the spray boxes reaches the set pressure, the cover plate completely avoids the nozzle seat. At this point, the water in the chambers of the spray boxes is sprayed out in a mist form through multiple nozzles on the nozzle seat. The water mist is sprayed obliquely towards the saplings, wetting the canopy of the saplings and allowing the leaves and branches to absorb the water. By installing spray boxes on both sides of the saplings... This system can thoroughly wet the canopy of saplings. After the canopy is sprayed, the output pressure of the water pump is reduced, causing the water pressure in the spray box chamber to decrease. This lowers the height of the vertical rod and cover plate, allowing the cover plate to block the water mist sprayed from the nozzle seat. The water mist is then sprayed directly onto the roots of the trees, thus directly irrigating them. Compared to existing technologies, it eliminates the need for supports to install water pipes and nozzles, making the setup simpler. It can provide overall spraying of saplings and specialized irrigation of the roots, reducing evaporation during root irrigation and saving energy and water.
[0006] Preferably, the water pressure assembly includes a piston cylinder, a piston, and a spring. The lower part of the piston cylinder is installed in the chamber of the spray box, and the upper part of the piston cylinder extends above the spray box. The lower end of the piston cylinder is open, and the piston is slidably installed inside the piston cylinder. A sealing ring is provided between the piston and the inner wall of the piston cylinder. The lower end of the vertical rod passes through the upper end plate of the piston cylinder and is connected to the piston. The lower end of the spring is connected to the piston, and the upper end of the spring is connected to the upper end plate of the piston cylinder. The spring elastically supports the piston downward, so that the vertical rod and the cover plate are in a low position. At this time, the cover plate covers the nozzle of the spray head seat. As the water pressure in the chamber of the spray box gradually increases, the water pressure pushes the piston upward along the piston cylinder, thereby compressing the spring. This causes the piston to drive the vertical rod and the cover plate to rise, realizing the linkage between the height of the vertical rod and the water pressure.
[0007] Preferably, it also includes a slide rod and a plug. The upper end of the slide rod is vertically installed on the inclined surface of the spray box. The slide rod is located inside the cavity of the spray box. The nozzle seat is slidably installed on the slide rod. The plug is installed at the lower end of the slide rod and is aligned with the input ends of multiple nozzles of the nozzle seat. A wear-resistant sealing ring is provided between the nozzle seat and the inclined surface of the spray box. When the water pressure in the spray box is low, the cover plate covers the nozzle seat and pushes the nozzle seat along the slide rod into the cavity of the spray box, so that the input ends of multiple nozzles of the nozzle seat are blocked by the plug, reducing water leakage in the spray box when the water pressure is low.
[0008] Preferably, it also includes a rod, which is installed on the lower end face of the sprinkler box; when laying the sprinkler box, the rod is inserted into the soil between the tree seedlings to improve the stability of the sprinkler box.
[0009] Preferably, it also includes a moisture sensor, which is installed inside the drill rod and has multiple water-permeable holes on its outer wall. The moisture sensor is electrically connected to the controller of the water pump. The moisture sensor detects the soil moisture content through the multiple water-permeable holes in the drill rod. When the moisture content is lower than the threshold, the water pump starts to run and begin sprinkler irrigation. When the moisture content reaches the threshold, the water pump stops, thereby stopping irrigation.
[0010] Preferably, it also includes a water collection box and a liquid level sensor. The water collection box is installed on the cover plate, and the liquid level sensor is installed in the water collection box. The liquid level sensor is electrically connected to the controller of the water pump. When the nozzle seat sprays water onto the canopy of the sapling, the falling water mist falls into the water collection box and is collected. When the liquid level in the water collection box comes into contact with the liquid level sensor, the spraying of the sapling canopy is completed. At this time, the liquid level sensor sends a signal to the controller of the water pump, causing the output water pressure of the water pump to decrease, thereby directly irrigating the roots of the sapling and realizing the automatic switching of the spraying mode.
[0011] Preferably, it also includes a mounting rod, which is installed in the water collection box, and the liquid level sensor is mounted on the mounting rod in a height-adjustable manner; adjusting the height of the liquid level sensor on the mounting rod adjusts the spraying intensity of the tree seedling canopy, thereby improving versatility.
[0012] Compared with the prior art, the advantages of this utility model are: it does not require the installation of supports to set up water pipes and nozzles, so the arrangement is simpler, and it can spray the entire tree seedlings and irrigate the roots separately, reducing the evaporation when watering the roots, and saving more energy and water.

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1
[0016] like Figures 1 to 7As shown, an energy-saving tree cultivation spraying device includes a water pump 1 and a water pipe 2, with the inlet end of the water pipe 2 connected to the outlet of the water pump 1. It also includes a spray box 3, a connector 4, a nozzle seat 5, a vertical rod 6, a cover plate 7, and a water pressure assembly. The spray box 3 has an internal chamber, and the connector 4 is installed on the spray box 3, communicating with the chamber. The end of the water pipe 2 is connected to the connector 4. The spray box 3 has an inclined surface, and the nozzle seat 5 is vertically installed on the inclined surface of the spray box 3. Multiple nozzles are installed on the nozzle seat 5, which communicates with the chamber of the spray box 3. The vertical rod 6 is vertically mounted on the spray box 3 and can be raised and lowered. The water pressure assembly is installed in the chamber of the spray box 3 and is connected to the vertical rod 6 via a transmission mechanism. The water pressure assembly drives the vertical rod 6 to rise and fall under the water pressure within the chamber of the spray box 3. The cover plate 7 is installed on the vertical rod 6 and is connected to the inclined surface of the spray box 3. Parallel, cover plate 7 is located above nozzle seat 5; the water pressure assembly includes piston cylinder 8, piston 9 and spring 10, the lower part of piston cylinder 8 is installed in the chamber of spray box 3, the upper part of piston cylinder 8 extends above spray box 3, the lower end of piston cylinder 8 is open, piston 9 is slidably installed inside piston cylinder 8, a sealing ring is provided between piston 9 and the inner wall of piston cylinder 8, the lower end of vertical rod 6 passes through the upper end top plate of piston cylinder 8 and is connected to piston 9, the lower end of spring 10 is connected to piston 9, and the upper end of spring 10 is connected to the upper end top plate of piston cylinder 8; it also includes slide rod 11 and block 12, the upper end of slide rod 11 is vertically installed on the inclined surface of spray box 3, slide rod 11 is located inside the chamber of spray box 3, nozzle seat 5 is slidably installed on slide rod 11, block 12 is installed on the lower end of slide rod 11, and block 12 is aligned with the input ends of multiple nozzles of nozzle seat 5.
[0017] When the water pressure in the spray box 3 is low, the spring 10 elastically supports the piston 9 downward, so that the vertical rod 6 and the cover plate 7 are in a low position. At this time, the cover plate 7 covers the nozzle of the nozzle seat 5 and pushes the nozzle seat 5 along the slide rod 11 into the cavity of the spray box 3, so that the input end of multiple nozzles of the nozzle seat 5 is blocked by the block block 12. A wear-resistant sealing ring is set between the nozzle seat 5 and the inclined surface of the spray box 3 to reduce water leakage in the spray box 3 when the water pressure is low. As the water pressure in the cavity of the spray box 3 gradually increases, the water pressure pushes the piston 9 upward along the piston cylinder 8, thereby compressing the spring 10, so that the piston 9 drives the vertical rod 6 and the cover plate 7 to rise, realizing the linkage between the height of the vertical rod 6 and the water pressure. During operation, multiple spray boxes 3 are connected in series via multiple water pipes 2. Each spray box 3 is connected to a water pump 1 via the water pipes 2. The spray boxes 3 are aligned with multiple tree seedlings, and the multiple nozzle seats 5 face the trees. Initially, the water pressure assembly lowers the vertical rod 6 to its lowest position, and the cover plate 7 covers the nozzles of the nozzle seats 5. The water pump 1 pressurizes the water and delivers it through the water pipes 2 to the chambers of the spray boxes 3. As the water pressure in the chambers of the spray boxes 3 gradually increases, the water pressure acts on the piston 9, pushing the vertical rod 6 and the cover plate 7 upwards, causing the cover plate 7 to detach from the nozzle seats 5. When the water pressure in the chambers of the spray boxes 3 reaches the set pressure, the cover plate 7 completely avoids the nozzle seats 5. At this point, the water in the chambers of the spray boxes 3 is misted through the multiple nozzles of the nozzle seats 5. The water mist is sprayed at an angle onto the saplings, wetting their crowns and allowing the leaves and branches to absorb the moisture. By installing spray boxes 3 on both sides of the saplings, the crowns can be fully wetted. After the crowns are wetted, the output pressure of the water pump 1 is reduced, causing the water pressure in the chamber of the spray box 3 to drop. This causes the spring 10 to push the piston 9, lowering the vertical rod 6 and the cover plate 7. The cover plate 7 then blocks the water mist sprayed from the nozzle seat 5, allowing the water mist to be sprayed directly onto the roots of the trees, thus directly irrigating them. Compared to existing technologies, this method eliminates the need for supports to install water pipes and nozzles, making the setup simpler. It allows for both overall spraying of the saplings and specialized irrigation of the roots, reducing evaporation during root irrigation and saving energy and water. Example 2
[0018] like Figure 1 , Figure 4 and Figure 5 As shown, based on Embodiment 1, it also includes a drill rod 13, which is installed on the lower end face of the spray box 3; it also includes a moisture sensor 14, which is installed inside the drill rod 13, and multiple water-permeable holes are provided on the outer wall of the drill rod 13; it also includes a water collection box 15 and a liquid level sensor 16, with the water collection box 15 installed on the cover plate 7 and the liquid level sensor 16 installed in the water collection box 15; it also includes a mounting rod 17, which is installed in the water collection box 15, and the liquid level sensor 16 is mounted on the mounting rod 17 in a liftable manner.
[0019] When installing the sprinkler box 3, the probe 13 is inserted into the soil between the saplings to improve the stability of the sprinkler box 3. The moisture sensor 14 is electrically connected to the controller of the water pump 1. The moisture sensor 14 detects the soil moisture content through multiple permeable holes in the probe 13. When the moisture content is lower than the threshold, the water pump 1 starts to run and begin sprinkler irrigation. When the moisture content reaches the threshold, the water pump 1 stops, thus stopping irrigation. The height of the liquid level sensor 16 on the mounting rod 17 is adjusted to adjust the position of the saplings. The level sensor 16 is electrically connected to the controller of the water pump 1 to control the spraying level of the sapling's canopy. When the nozzle seat 5 sprays the canopy of the sapling, the falling water mist falls into the water collection box 15 and is collected. When the liquid level in the water collection box 15 comes into contact with the level sensor 16, the spraying of the sapling's canopy is completed. At this time, the level sensor 16 sends a signal to the controller of the water pump 1, causing the output water pressure of the water pump 1 to decrease, thereby directly irrigating the roots of the sapling and realizing the automatic switching of the spraying mode.
[0020] like Figures 1 to 7 As shown, this utility model discloses an energy-saving sprinkler device for tree cultivation. During operation, multiple sprinkler boxes 3 are connected in series via multiple water pipes 2. The sprinkler boxes 3 are connected to a water pump 1 via the water pipes 2. The sprinkler boxes 3 are aligned with multiple tree seedlings, and the multiple nozzle seats 5 face the trees. Initially, a spring 10 lowers the vertical rod 6 to its lowest position, and a cover plate 7 covers the nozzles of the nozzle seats 5. Then, the water pump 1 pressurizes water and delivers it through the water pipes 2 to the chambers of the sprinkler boxes 3. As the water pressure in the chambers of the sprinkler boxes 3 gradually increases, the water pressure pushes the piston 9 upwards along the piston cylinder 8, compressing the spring 10. This causes the piston 9 to raise the vertical rod 6 and the cover plate 7, disengaging the cover plate 7 from the nozzle seats 5. Then, when the water pressure in the chambers of the sprinkler boxes 3 reaches the set pressure, the cover plate 7... Plate 7 completely avoids the nozzle seat 5. At this time, the water in the chamber of the spray box 3 is sprayed out in the form of water mist through multiple nozzles of the nozzle seat 5. The water mist is sprayed obliquely towards the sapling, wetting the crown of the sapling, allowing the leaves and branches to absorb the water. The falling water mist falls into the water collection box 15 for collection. When the liquid level in the water collection box 15 contacts the liquid level sensor 16, the spraying of the sapling crown is completed. At this time, the liquid level sensor 16 sends a signal to the controller of the water pump 1, causing the output water pressure of the water pump 1 to decrease, which causes the water pressure in the chamber of the spray box 3 to decrease. This causes the spring 10 to lower the height of the vertical rod 6 and the cover plate 7, so that the cover plate 7 blocks the water mist sprayed from the nozzle seat 5, allowing the water mist to be sprayed directly onto the roots of the tree, thus directly watering the roots. Finally, when the moisture sensor 14 detects that the soil moisture content has reached the threshold, the water pump 1 stops, thus stopping irrigation.
[0021] The main functions achieved by this utility model are: 1. No support frame is needed to install water pipes and sprinklers, making the setup simpler. It can spray the entire tree seedling and irrigate the roots separately, reducing evaporation when watering the roots and saving more energy and water. 2. Good sealing performance reduces water leakage; 3. It can automatically start and stop based on soil moisture content; 4. It can automatically switch the spraying mode according to the degree of tree canopy spraying.
