Description
Technical Field
[0001] This utility model relates to the field of irrigation equipment, and in particular to a water and fertilizer fixed-point spraying device. Background Technology
[0002] Plants cannot grow without two basic nutrients: water and fertilizer. Fertilizers are classified into solid fertilizers and liquid fertilizers based on their state, with urea being a common example of a liquid fertilizer. Because liquid fertilizers can address both nutrient and moisture deficiencies in the soil, they are particularly suitable for cultivating small plants. Liquid fertilizers can be applied to the plants using a sprayer.
[0003] However, during the cultivation of flowers, it is usually necessary to equip two sets of spraying devices: one set sprays water and fertilizer on the plants to maintain soil nutrition; the other set sprays moisturizing water on the petals to ensure their freshness.
[0004] However, the setup of two spraying devices leads to a messy pipeline distribution, which is not conducive to management. At the same time, since the water and fertilizer and moisturizing liquid are sprayed at different locations, the height of the traditional spraying device cannot be adjusted after the nozzles are set, thus making it impossible to achieve equipment integration.
[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0024] See Figure 1 This utility model provides a water and fertilizer fixed-point spraying device, which includes a bracket 1 and a spraying component 2 installed thereon;
[0025] The support 1 adopts a column structure, with a fixed end 11 at its lower end, which can be inserted into the soil or other fixed components. In this embodiment, the fixed end 11 of the support 1 is also provided with support legs 12 around its perimeter. This structure is suitable for flowerpot layouts. When fixed, the fixed end 11 is inserted into the gap between multiple flowerpots, and the support legs 12 are inserted into the soil inside the flowerpots to fix the support 1. Preferably, the support 1 is vertical after being fixed. The support 1 is a columnar structure with a predetermined cross-section. The cross-section can be square or circular. For example, in this example, to facilitate the angle adjustment of the sliding frame 21 and increase flexibility, the support 1 adopts a circular column.
[0026] The spraying component 2 is mounted on the bracket 1 and switches between two states after being positioned: a first working state and a second working state with different height differences.
[0027] In the first state, the spraying component 2 is positioned at the height of the support 1. In this state, the spraying component 2 sprays a moisturizing liquid (water is sufficient). The spraying component 2 sprays the moisturizing liquid onto the branches and leaves at the height position to ensure the branches and leaves remain moist. In the second state, the spraying component 2 is positioned at the lower height of the support 1. In this state, the spraying component 2 sprays a water-fertilizer mixture. The spraying component 2, at the lower height position, sprays the water-fertilizer mixture onto the plant roots to avoid spraying the water-fertilizer mixture onto the branches and leaves or sensitive parts of the plant, which could cause damage.
[0028] The spraying component 2 includes a sliding frame 21 that is fitted onto the bracket 1 and at least one spray head 3 for spraying irrigation liquid, wherein the spray head 3 is connected to the sliding frame 21.
[0029] In the first embodiment, the spray head 3 can be fixedly connected to the sliding frame 21, using an integral molding or fixed snap-fit structure.
[0030] Alternatively, as shown in the second embodiment, the spray head 3 is configured as an adjustable structure. Specifically, the spray head 3 can be angularly adjusted relative to the axis of the sliding frame 21; a support rail 22 is externally connected to the sliding frame 21; the spray head 3 is slidably mounted on the support rail 22. The sliding frame 21 is provided with a pipe connection port 25, which is connected to a liquid (moisturizing liquid or fertilizer) supply device via a pipe; the sliding frame 21 has a liquid storage space inside, and the channel inside the spray head 3 is connected to the liquid storage space inside the sliding frame 21. The liquid flow process is as follows: the liquid enters the liquid storage space of the sliding frame 21 from the supply device and is further sprayed out by the spray head 3. The spray head 3 is configured as an adjustable structure because the spraying component 2 has different atomization requirements at different heights. When the spray head 3 is at a certain height, its atomization range is wide, and the specific position of the spray head 3 is not specifically required. When the spray head 3 is in a low position, its atomization range is narrow, and the atomization direction of the spray head 3 may not correspond to the root position of the plant. Therefore, the position of the spray head 3 needs to be adjusted. During the adjustment process, the spray head 3 can be manually driven and finely adjusted on the support rail 22. After adjustment, the spray direction of the spray head 3 is aligned with the root position of the plant.
[0031] Of course, the spray head 3 can also be directly connected to an external liquid supply device, that is, the spray head 3 is connected to the supply device through a hose.
[0032] See Figure 1 , Figure 2 and Figure 3In the above, the positioning structure includes an annular protrusion 13 for limiting the low position and a longitudinal strip protrusion 14 for limiting the high position; the longitudinal strip protrusion 14 has an adjustment space H at the top of the bracket 1 that can accommodate the sliding frame 21 so as to adjust the locking angle; the inner wall of the sliding frame 21 is provided with a through groove 211 and a positioning groove 212 to facilitate its entry into the upper adjustment space through the longitudinal strip protrusion 14.
[0033] See Figure 1 and Figure 4 In the third embodiment, the spraying component 2 and spray head 3, located in the first working state, are connected to a swing structure to achieve swinging operation within a predetermined angle. This swinging operation further expands the atomization range of the spray head 3. Specifically, the swing structure includes a flexible connector 10 that mates with the spray head 3. The connector 10 is made of rigid plastic and has a micro-deformation effect. The spray head 3 has a slot 31, and the end of the connector 10 is inserted into the slot 31.
[0034] See Figure 2 and Figure 5 Multiple connectors 10 are provided and are connected to a ring 101. The ring 101 is connected to a motor 102 through a gear structure. The motor 102 generates a oscillating driving force to drive the connectors 10 to oscillate.
[0035] In summary, this utility model provides a water and fertilizer fixed-point spraying device, including a bracket and a spraying component installed on it. The bracket adopts a column structure with a fixed end at its lower end, which can be inserted into the soil or other fixed components. Support legs are also provided around the fixed end of the bracket. This structure is suitable for flowerpot layouts. When fixed, the fixed end is inserted into the gap between multiple flowerpots, and the support legs are inserted into the soil within the flowerpots to fix the bracket. After fixing, the bracket is in a vertical position. The bracket is a columnar structure with a predetermined cross-section, which can be square or circular, facilitating angle adjustment of the sliding frame to increase flexibility. The bracket uses a circular column. The spraying component is installed on the bracket and switches between two states after being positioned: a first working state with different height differences and a second working state. In the first state, the spraying component is at the height of the bracket, and in this state, the spraying component sprays a moisturizing liquid onto the branches and leaves to keep them moist. In the second state, the spraying component is positioned at a low angle on the support. In this state, the spraying component sprays water and fertilizer, directing the water and fertilizer to the plant roots while maintaining a low position. This avoids spraying water and fertilizer onto branches, leaves, or sensitive areas of the plant, preventing damage. This invention allows for: 1. Adjusting the height of the spray head according to the different application points of the moisturizing solution and fertilizer; 2. Expanding the atomization range of the spray head and optimizing the spraying effect of the moisturizing solution.
[0036] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
