Description

Technical Field

[0001] This utility model relates to an atomizing spraying device, and more particularly to a portable rice foliar fertilizer atomizing spraying device. Background Technology

[0002] Atomizing sprayers are agricultural devices that use atomization technology to convert liquid fertilizers or pesticides into fine droplets and spray them evenly onto the leaves of crops. Because nutrients such as nitrogen and potassium are easily soluble in water and can be easily washed away in paddy fields, reducing soil fertilization efficiency, foliar spraying is often used in rice cultivation to reduce reliance on soil fertilization and thus improve fertilizer utilization. Furthermore, compared to traditional soil fertilization, nutrients from foliar spraying can be absorbed by crops within hours, making it particularly suitable for quickly replenishing nutrients when rice shows signs of nutrient deficiency or root absorption is hindered. This plays a crucial role in improving rice yield and quality.

[0003] However, existing atomizing spraying devices still have certain shortcomings in practical applications: Rice cultivation covers a wide area, and fields are often irregularly shaped; traditional atomizing spraying devices are usually equipped with fixed-size nozzles, making it difficult to flexibly adapt to the spraying needs of different areas. Therefore, when the nozzle coverage area does not match the field size, operators can only ensure coverage by overlapping spray areas, which not only leads to fertilizer waste but may also cause fertilizer damage due to localized overspraying; if the spraying amount is reduced to avoid waste, some areas may be missed, affecting the fertilization effect.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the structure of the atomizing spraying device, as follows:

[0024] A portable rice foliar fertilizer atomizing spraying device, such as Figures 1-3As shown, the system includes: a housing 1, a liquid level plate 21, a shoulder strap 2, an inlet 3, a sealing cap 31, a connecting rope 22, a battery 4, a controller 41, a supply pipe 6, a spray head 7, a pump body 5, a guide plate 18, and a control valve 71. A liquid level plate 21 is fixedly installed on the housing 1 to display the liquid level of the fertilizer solution inside, allowing for observation and timely replenishment. A shoulder strap 2 is fixedly installed on the rear side of the housing 1; the length of the shoulder strap 2 can be adjusted according to the user's habits to improve comfort. An inlet 3 for adding fertilizer is provided on the housing 1. A sealing cap 31 is used to plug the inlet 3. A connecting rope 22 is fixedly installed between the sealing cap 31 and the housing 1 to prevent the sealing cap 31 from being lost. The bottom of the housing 1 is fixedly... A storage battery 4 is fixedly installed on the housing 1; a controller 41 for controlling this device is fixedly installed on the housing 1, and the storage battery 4 is electrically connected to the controller 41, providing power for the operation of the controller 41; a supply pipe 6 is fixedly installed at the bottom of the housing 1, and the supply pipe 6 has three sections; a spray head 7 for atomizing fertilizer solution is fixedly installed on the supply pipe 6; a pump body 5 is fixedly installed at the end of the supply pipe 6, and the pump body 5 is located inside the housing 1 and is electrically connected to the controller 41; a guide plate 18 is fixedly installed at the bottom of the housing 1, and the guide plate 18 guides the fertilizer to the pump body 5 to reduce fertilizer solution residue; control valves 71 are fixedly installed at the left and right ends of the supply pipe 6 in the middle position, and the control valves 71 are used to control the opening and closing of the left and right sections of the supply pipe 6.

[0025] Open the sealing cap 31 and add fertilizer solution into the tank 1 through the addition port 3. After filling, close the sealing cap 31 again. Then, start the pump 5 to deliver the fertilizer to the supply pipe 6. The fertilizer is sprayed out as uniform droplets through the spray head 7. The three independently controlled supply pipes 6 work in conjunction with the control valve 71 to flexibly open and close each section. Therefore, when large-scale spraying is required, all three supply pipes 6 can be controlled to work simultaneously, while for small-scale spraying, some supply pipes 6 can be selectively closed, making the spraying range of this device adjustable. This adjustable design allows the device to adapt to the operational needs of paddy fields of different sizes, ensuring spray uniformity and solving the problems of fertilizer waste or missed spraying caused by the fixed spray width of traditional equipment, thereby improving the fertilization accuracy and operational efficiency of this device.

[0026] like Figures 1-4As shown, the spraying device further includes: a corrugated pipe 8, a limiting plate 9, a connecting block 10, a fixing block 11, an iron sheet 12, and a magnet 13; a corrugated pipe 8 is fixedly installed between two adjacent supply pipe sections 6, the position of the middle supply pipe section 6 is fixed, and the corrugated pipe 8 allows the other two sections to move; limiting plates 9 are fixedly installed on the left and right sides of the bottom of the box body 1; a connecting block 10 is slidably installed on the limiting plate 9; a fixing block 11 is fixedly installed on the left and right supply pipe sections 6, and the fixing block 11 is rotatably installed corresponding to the connecting block 10; an iron sheet 12 is fixedly installed on the left and right sides of the middle part of the box body 1; a magnet 13 is fixedly installed on both the left and right supply pipe sections 6, and the magnet 13 is magnetically connected to the iron sheet 12.

[0027] When using the supply pipe 6 in segments, the operator can quickly adjust the working position of the supply pipe 6 by folding it, facilitating flexible use of the device. When the supply pipe 6 needs to be unfolded, the magnet 13 is separated from the iron plate 12, the left and right segments of the supply pipe 6 are removed from the upper housing 1, and then these two segments of the supply pipe 6 are rotated to a horizontal position. At this time, the connecting block 10 will slide along the limiting plate 9, and finally the limiting plate 9 and the connecting block 10 form a stable support structure, ensuring that the supply pipe 6 remains in a horizontal working state, thus completing the unfolding operation. Conversely, when the supply pipe 6 needs to be folded, the two segments of the supply pipe 6 are reversed and the magnet 13 is controlled to attract the iron plate 12. Therefore, the above settings make the device more portable and adaptable to different sites, and ensure structural stability in the working state.

[0028] like Figures 1-3 As shown, the spraying device further includes: a stirring blade 16 and a handle 17; the stirring blade 16 is rotatably installed inside the housing 1; the handle 17 is rotatably installed on the top of the housing 1, and the handle 17 is fixedly installed with the stirring blade 16. When it is necessary to dissolve solid fertilizer or dilute concentrated liquid fertilizer, the operator will add fertilizer and water into the housing 1 according to the recommended ratio, and then use the handle 17 to rotate the stirring blade 16 to stir the water and fertilizer, achieving rapid and uniform mixing or dissolution. Therefore, the above-mentioned configuration enables the device to improve fertilizer utilization efficiency and application uniformity while ensuring ease of operation, further enhancing the practical value and operational adaptability of the device.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, the spraying device further includes: a recycling box 14, a filter screen 141, a waste liquid box 15, a cover plate 19, and a placement box 20; the recycling box 14 is fixedly installed on the left side of the box body 1, and the recycling box 14 has no bottom; the filter screen 141 is fixedly installed on the bottom of the recycling box 14; the waste liquid box 15 is slidably installed on the bottom of the recycling box 14; the cover plate 19 is rotatably installed on the top of the recycling box 14, and the cover plate 19 is snap-fitted to the recycling box 14; the placement box 20 is fixedly installed on the right side of the box body 1. When working outdoors, operators can use a dedicated recycling box 14 to place fertilizer packaging waste to prevent packaging from being discarded and polluting the environment. The filter 141 can effectively separate residual fertilizer on the packaging, preventing fertilizer from contaminating the packaging surface and making subsequent cleaning difficult. Finally, the waste liquid box 15 can be slid out to clean the fertilizer waste inside. The cover 19 is used to ensure the safe storage of packaging waste to prevent loss. This device can also use the placement box 20 to place the operator's personal items, reducing the need for operators to carry additional storage tools and improving the convenience and environmental friendliness of field operations.
