Description

Technical Field

[0001] This utility model is a spraying device for green plants, belonging to the field of landscaping. Background Technology

[0002] Oxidative spraying for garden plants is a plant care technology that combines atomized hydration with environmental regulation. The spraying equipment converts water or nutrient solution into droplets, which are then evenly sprayed onto the leaves and surrounding environment of the plants. This provides humid conditions for plant growth and regulates the local microclimate through atomization. It also helps improve the photosynthetic and respiratory functions of plant leaves, and is widely used in garden landscape maintenance and greenhouse plant cultivation. In greenhouse plant cultivation, nozzles are installed on the main water supply pipeline. These nozzles atomize water into droplets to hydrate the greenhouse plants. However, under constant water pressure, the spray range of the nozzles is limited. For areas at the edge of the planting area, some droplets may spray directly outside the planting area, resulting in water waste. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spraying device for green plants to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for green plants, comprising: The connecting pipe has an L-shaped structure; A multi-faceted cap is installed on the upper part of the vertical section of the connecting pipe. Multiple thin tubes arranged in a ring at equal intervals are installed on the side of the multi-faceted cap. A first nozzle is installed at the end of the thin tubes away from the multi-faceted cap. A conical sleeve is provided on the upper side of the polygonal cap to limit the spray range of the first nozzle. A detachable column is installed at the middle position of the upper surface of the polygonal cap. The column passes through the conical sleeve, and the conical sleeve maintains a fixed relative position with the column by a positioning screw.

[0005] Furthermore, a tube sleeve is installed on the upper end of the conical sleeve, the tube sleeve is fitted onto the column rod, a threaded hole is opened on the outer surface of the tube sleeve, the positioning screw is threaded into the threaded hole, and one end of the positioning screw is in contact with the surface of the column rod.

[0006] Furthermore, an outer retaining ring is installed at the lower end of the conical sleeve, and a bottom ring is installed at the lower end of the outer retaining ring. An inner retaining ring is provided on the inner side of the outer retaining ring and is arranged concentrically with the outer retaining ring. The lower end of the inner retaining ring is connected and fixed to the bottom ring. The inner retaining ring, the outer retaining ring and the bottom ring together form a space for collecting water. A pipe connector for connecting the drain pipe is installed at the bottom of the bottom ring.

[0007] Furthermore, the inner retaining ring and the bottom ring are integrally formed, and the outer retaining ring, the bottom ring, and the conical sleeve are integrally formed.

[0008] Furthermore, a U-shaped frame is fixedly connected to the lower end of the column rod, and a connecting lug is inserted inside the U-shaped frame. The lower end of the connecting lug is fixedly connected to a polygonal cap. Two first small holes are opened on each of the two parallel sides of the U-shaped frame, and two second small holes that mate with the first small holes are opened on one side of the connecting lug. A connecting screw is inserted into the channel formed by the first and second small holes, and a nut is threaded to one end of the connecting screw.

[0009] Furthermore, a plurality of second nozzles are installed at the lower part of the outer surface of the thin tube, and the plurality of second nozzles are arranged at equal intervals along the length of the thin tube.

[0010] Furthermore, the inner wall of the polygonal cap is machined with an internal thread, and the upper end of the vertical part of the connecting pipe is machined with an external thread that matches the internal thread. The end of the connecting pipe with the external thread is threadedly connected to the polygonal cap.

[0011] Furthermore, a connecting ring is fixed to the end of the connecting tube away from the polygonal cap, and a plurality of circular holes for inserting bolts are equidistantly opened on one side of the connecting ring.

[0012] The beneficial effects of this utility model are: A conical sleeve covers the upper side of the polygonal cap. Its conical structure physically blocks the water mist sprayed by the first nozzle. By moving the conical sleeve up and down along the column and fixing it with positioning screws, the height and range of the shielding can be flexibly adjusted. When used at the edge of the greenhouse planting area, moving the conical sleeve downwards reduces the water mist spray angle, preventing some of the water mist from spreading outside the planting area; moving it upwards expands the spray range, adapting to the water replenishment needs inside the planting area. This design breaks the limitations of traditional nozzles with fixed spray ranges, allowing control of the water mist coverage area according to the planting area boundary, preventing edge water mist from spraying into non-planting areas, and reducing water waste.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-3 This utility model provides a technical solution: a spraying device for green plants, including a connecting pipe 1, which is an L-shaped structure. A connecting ring 11 is fixed to one end of the connecting pipe 1 away from the polygonal cap 2. A plurality of circular holes for inserting bolts are equidistantly opened on one side of the connecting ring 11. The connecting ring 11 is connected to the flange on the water supply main pipe by bolts, thereby completing the assembly of the connecting pipe 1 and the water supply main pipe.

[0016] The polygonal cap 2 is installed on the upper part of the vertical section of the connecting pipe 1. The inner wall of the polygonal cap 2 is machined with an internal thread, and the upper part of the vertical section of the connecting pipe 1 is machined with an external thread that matches the internal thread, so that the end of the connecting pipe 1 with the external thread is threadedly connected to the polygonal cap 2, which facilitates the separation of the connecting pipe 1 and the polygonal cap 2. Multiple thin tubes 21 are installed on the side of the polygonal cap 2 in a ring and equidistant arrangement. A first nozzle 22 is installed at the end of the thin tube 21 away from the polygonal cap 2. Multiple second nozzles 23 are installed at the lower part of the outer surface of the thin tube 21. The multiple second nozzles 23 are equidistantly arranged along the length of the thin tube 21. The first nozzle 22 and the second nozzle 23 together increase the number of water mist spray points.

[0017] A conical sleeve 3 is set on the upper side of the polygonal cap 2 to limit the spray range of the first nozzle 22. A detachable column rod 32 is installed in the middle of the upper surface of the polygonal cap 2. A U-shaped frame 38 is fixedly connected to the lower end of the column rod 32. A connecting ear 24 is inserted in the U-shaped frame 38. The lower end of the connecting ear 24 is fixedly connected to the polygonal cap 2. Two first small holes are opened on the two parallel sides of the U-shaped frame 38. Two second small holes that mate with the first small holes are opened on one side of the connecting ear 24. A connecting screw 4 is inserted in the channel formed by the first small holes and the second small holes. A nut 41 is threaded to one end of the connecting screw 4. The fastener formed by the connecting screw 4 and the nut 41 limits the relative position of the connecting ear 24 and the U-shaped frame 38, thus completing the assembly of the column rod 32 and the polygonal cap 2.

[0018] See Figures 1-4 The column rod 32 passes through the conical sleeve 3. The conical sleeve 3 maintains a fixed relative position with the column rod 32 through the positioning screw 33. A tube sleeve 31 is installed at the upper end of the conical sleeve 3, and the tube sleeve 31 is fitted onto the column rod 32. A threaded hole is opened on the outer surface of the tube sleeve 31, and the positioning screw 33 is threaded into the threaded hole. One end of the positioning screw 33 contacts the surface of the column rod 32. The conical sleeve 3 has an inverted cone shape, covering the upper side of the polygonal cap 2 and enclosing all the thin tubes 21 and the first nozzle 22. When the first nozzle 22 sprays water in all directions under water pressure... When water mist is sprayed, the inclined surface of the conical sleeve 3 can form a uniform physical shield for the water mist. The water mist that might otherwise spread outward from the planting area will be blocked by the inner wall of the conical sleeve 3 and its movement direction will be changed, and it will be redirected to the inside of the planting area. At the same time, the annular coverage characteristic of the conical sleeve 3 can form a 360° all-round shield for multiple sets of first nozzles 22, avoiding spray deviation caused by shielding in a single direction, ensuring that the water mist always spreads within a controllable range, reducing ineffective spraying into non-planting areas (such as greenhouse walls, passageways, and equipment supports) from the source, and reducing water waste.

[0019] When used at the edge of the greenhouse planting area, workers can loosen the positioning screw 33 and move the conical sleeve 3 downwards along the column 32. As the height of the conical sleeve 3 decreases, its blocking area on the first nozzle 22 increases, and the water mist spray angle decreases accordingly. This blocks water mist directed outwards from the planting area, leaving only the spray range directed inwards, perfectly meeting the need for narrow-range water replenishment in the edge area. When used inside the planting area, moving the conical sleeve 3 upwards reduces the blocking area and expands the water mist spray angle, allowing the water mist to cover a wider area and meeting the need for large-area, uniform water replenishment for the plants inside. This adjustment does not require replacing nozzles or adjusting water pressure; it can be completed through simple mechanical operation. It flexibly adapts to the differentiated water replenishment needs of the edges and interior of the greenhouse, as well as planting areas of different sizes, avoiding the cumbersome and costly process of customizing special nozzles for different areas.

[0020] See Figure 1 , Figure 2 and Figure 4 An outer baffle ring 34 is installed at the lower end of the conical sleeve 3, and a bottom ring 35 is installed at the lower end of the outer baffle ring 34. An inner baffle ring 37 is arranged concentrically with the outer baffle ring 34 on the inner side of the outer baffle ring 34. The lower end of the inner baffle ring 37 is connected and fixed to the bottom ring 35. The inner baffle ring 37, the outer baffle ring 34 and the bottom ring 35 together form a space for collecting water. A pipe connector 36 for connecting the drain pipe is installed at the bottom of the bottom ring 35. The inner baffle ring 37 and the bottom ring 35 are integrally formed structures. The outer baffle ring 34, the bottom ring 35 and the conical sleeve 3 are integrally formed structures. The inner baffle ring 37, the outer baffle ring 34 and the bottom ring 35 at the lower end of the conical sleeve 3 together form an annular groove-shaped recycling space. The water mist blocked by the conical sleeve 3 will fall into this space, avoiding direct dripping to the ground and causing waste. The pipe connector 36 at the bottom of the bottom ring 35 can be connected to the drain pipe to guide the recovered water back to the greenhouse water supply system or water storage tank, realizing the recycling of water resources. It is especially suitable for large-scale greenhouse cultivation scenarios, and long-term use can reduce the total water replenishment and water treatment costs.
