Description

Technical Field

[0001] This utility model relates to the field of pesticide and fertilizer spraying technology, and in particular to a pesticide and fertilizer atomization spraying device. Background Technology

[0002] Atomized fertilizer spraying devices are agricultural machines that atomize liquid preparations such as pesticides and foliar fertilizers and spray them evenly onto crops. They are divided into two categories: manual and electric. Manual sprayers use a manual lever or rocker to drive a liquid pump, which pressurizes the pesticide and fertilizer solution in the tank. The pressurized solution is then transported through pipelines to the nozzle and sprayed at high speed. Due to the sudden pressure drop, the solution is instantly atomized into tiny droplets, which are then evenly covered on the surface of the crops by airflow or gravity.

[0003] A spraying box for easy cleaning is disclosed in Chinese Patent Publication No. CN221532622U. This easy-to-clean spraying box uses a cleaning scraper to scrape and clean the inner wall of the water tank, which improves the cleaning efficiency and quality of the spraying box and avoids the problem of drug mixing caused by inadequate cleaning. However, according to the easy-to-clean spraying boxes provided in related fields and existing technologies, the atomization range of traditional spraying equipment is mostly a fixed value. When operating in fields with varying crop row spacing and planting density, if the range is too large, the pesticide and fertilizer will drift into non-target areas, increasing costs and environmental risks. If the range is too small, frequent movement of equipment is required, reducing work efficiency and increasing labor intensity. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a pesticide and fertilizer atomization spraying device.

[0005] The purpose of this utility model is achieved through the following technical solution: a pesticide and fertilizer atomization spraying device, including a sprayer body, a delivery pipe fixedly installed on the sprayer body, a spray gun fixedly installed at the end of the delivery pipe, a fixed sleeve fixedly provided at the end of the spray gun, an atomization component for adjusting the atomization particle size installed inside the fixed sleeve, and an adjustment component for adjusting the atomization range installed on the atomization component.

[0006] The atomizing component includes a connector threaded inside the fixed sleeve. An adjusting sleeve is threaded onto the end of the connector away from the fixed sleeve. A fixing ring is fixedly provided at the center of the connector. A core rod is fixedly provided at the center of the fixing ring. A valve core is fixedly provided at the end of the core rod away from the fixing ring.

[0007] Preferably, the adjusting assembly includes a first shrink sleeve threaded onto the outside of the adjusting sleeve, a second shrink sleeve threaded onto the outside of the first shrink sleeve, a third shrink sleeve threaded onto the outside of the second shrink sleeve, and a fourth shrink sleeve threaded onto the outside of the third shrink sleeve.

[0008] Preferably, the outlet of the adjusting sleeve is an outwardly expanding cone shape, and the valve core is located in the cone-shaped region at the outlet of the adjusting sleeve.

[0009] Preferably, the outlets of the first shrink sleeve, the second shrink sleeve, the third shrink sleeve, and the fourth shrink sleeve are all conical, and the conical shape at the outlet of the adjusting sleeve continues from the inside to the outside.

[0010] Preferably, the side of the valve core facing the fixing ring is tapered, and the outer diameter of the valve core is smaller than the inner diameter of the fixing sleeve.

[0011] Preferably, the outer surfaces of the first shrink sleeve, the second shrink sleeve, and the third shrink sleeve are symmetrically provided with two friction plates, and the friction plates on the first shrink sleeve, the second shrink sleeve, and the third shrink sleeve are staggered.

[0012] Preferably, a sealing gasket is provided between the connector and the fixing sleeve.

[0013] The beneficial effects of this pesticide and fertilizer atomization spraying device are as follows: By setting up atomization components and adjustment components, the droplet size can be adjusted using the adjustment sleeve to dynamically match the needs of fine mist for foliar topdressing and coarse mist for soil pest control, thereby improving the utilization rate of pesticides and fertilizers. In addition, the atomization range can be graded and controlled using a four-stage shrink sleeve to adapt to different crop row spacing and density, avoiding pesticide and fertilizer drift and environmental risks caused by excessive range, reducing the frequency of movement when the range is too small, reducing manual labor intensity, and comprehensively improving work efficiency. At the same time, the friction plates set alternately on the shrink sleeve can prevent interference between adjacent shrink sleeves, ensuring that the adjustment action of each level is independent and reliable, and achieving precise adjustment.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0024] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0025] like Figures 1 to 7 As shown, a pesticide and fertilizer atomization spraying device includes a sprayer body 1, a delivery pipe 2 fixedly installed on the sprayer body 1, a spray gun 3 fixedly installed at the end of the delivery pipe 2, a fixing sleeve 4 fixedly installed at the end of the spray gun 3, an atomizing component for adjusting the atomization particle size installed inside the fixing sleeve 4, and an adjusting component for adjusting the atomization range installed on the atomizing component. This device uses the sprayer body 1 as the core power and storage unit, applies pressure to the pesticide and fertilizer mixture in the sprayer body 1, so that the pesticide and fertilizer liquid is stably delivered to the spray gun 3 along the delivery pipe 2 under pressure. The spray gun 3, as the execution component of the delivery terminal, converts the high-pressure pesticide and fertilizer liquid into fine droplets through the atomizing component inside the fixing sleeve 4, and then the diffusion range of the droplets is precisely controlled by the adjusting component, ultimately achieving efficient and uniform spraying of pesticides and fertilizers.

[0026] like Figures 3 to 5As shown, the atomizing assembly includes a connector 6 threaded inside a fixed sleeve 4. An adjusting sleeve 7 is threaded onto the end of the connector 6 away from the fixed sleeve 4. A fixed ring 12 is fixedly positioned at the center of the connector 6, and a core rod 13 is fixedly positioned at the center of the fixed ring 12. A valve core 14 is fixedly positioned at the end of the core rod 13 away from the fixed ring 12. The side of the valve core 14 facing the fixed ring 12 is conical, and the outer diameter of the valve core 14 is smaller than the inner diameter of the fixed sleeve 4. The outlet of the adjusting sleeve 7 is an outwardly expanding conical shape, and the valve core 14 is located in the conical region at the outlet of the adjusting sleeve 7. A sealing gasket 5 is provided between the connector 6 and the fixed sleeve 4. High-pressure fertilizer solution enters the interior of the connector 6 through the spray gun 3 and flows at high speed along the annular flow channel between the fixed ring 12 and the core rod 13, ultimately impacting the conical surface of the valve core 14. Because the side of the valve core 14 facing the fixed ring 12 is conical, and the outer diameter of the valve core 14 is smaller than the inner diameter of the fixed sleeve 4, the high-speed flowing fertilizer solution impacts the conical surface. The surface undergoes turning and acceleration, forming a high-speed jet. Subsequently, the high-speed jet enters the outwardly expanding conical region at the outlet of the regulating sleeve 7. Here, the flow channel suddenly expands, causing a sharp drop in pressure. The fertilizer solution undergoes violent turbulence and breakup due to the sudden pressure change, forming droplets. At the same time, the outwardly expanding conical structure of the regulating sleeve 7 guides the broken droplets, preventing them from coalescing at the outlet and improving atomization uniformity. The sealing gasket 5 between the connector 6 and the fixed sleeve 4 prevents leakage of the high-pressure fertilizer solution, ensuring pressure stability and providing a guarantee for efficient atomization. By rotating the regulating sleeve 7 to change its relative position with the connector 6, the depth of the valve core 14 in the conical region of the regulating sleeve 7 can be indirectly adjusted, changing the gap between the valve core 14 and the regulating sleeve 7, thereby changing the orifice diameter of the liquid and achieving adjustment of the atomization particle size. The deeper the valve core 14 penetrates into the regulating sleeve 7, the larger the jet impact angle and the finer the droplets; conversely, the shallower the penetration, the coarser the droplets.

[0027] like Figures 3 to 6As shown, the adjusting assembly includes a first shrink sleeve 8 threaded onto the outside of the adjusting sleeve 7, a second shrink sleeve 9 threaded onto the outside of the first shrink sleeve 8, a third shrink sleeve 10 threaded onto the outside of the second shrink sleeve 9, and a fourth shrink sleeve 11 threaded onto the outside of the third shrink sleeve 10. The outlets of the first shrink sleeve 8, second shrink sleeve 9, third shrink sleeve 10, and fourth shrink sleeve 11 are all tapered, and the tapering shape continues from the inside out at the outlet of the adjusting sleeve 7. Two friction plates 15 are symmetrically arranged on the outer surfaces of the first shrink sleeve 8, second shrink sleeve 9, and third shrink sleeve 10, and the friction plates 15 on the first shrink sleeve 8, second shrink sleeve 9, and third shrink sleeve 10 are staggered. The first shrink sleeve 8, second shrink sleeve 9, third shrink sleeve 10, and fourth shrink sleeve 11 are connected by threads. The conical outlet shapes of the conical sleeves are nested sequentially, with each conical sleeve's outlet shape continuing from the inside out. Initially, the sprayed droplets are ejected outward along the continuous conical surfaces, and the spraying range is unrestricted, reaching its maximum value. When it is necessary to reduce the spraying range, the conical sleeves of different levels are rotated outward, breaking the continuous conical surfaces. A new outlet guide channel is formed on the inner surface, limiting the diffusion range of the droplets and thus changing the atomization range. In addition, the staggered friction plates 15 symmetrically arranged on the outer surfaces of the first to third conical sleeves 10 increase the hand friction during rotation, facilitating precise adjustment by the operator. Furthermore, the staggered structure avoids interference with adjacent conical sleeves when adjusting a certain level, ensuring that the adjustment actions of each level are independent and reliable.

[0028] The work process is as follows:

[0029] S1: As Figure 4 and Figure 5 As shown, the atomization particle size is set by rotating the adjusting sleeve 7 according to the type of crop being sprayed, its growth stage, and the presence of pests and diseases: if fine spraying is required (such as foliar fertilization), rotating the adjusting sleeve 7 reduces the gap between the valve core 14 and the adjusting sleeve 7 to obtain fine droplets; if spraying is required around the roots (such as insecticides), rotating the adjusting sleeve 7 increases the gap between the valve core 14 and the adjusting sleeve 7 to obtain relatively large droplets to avoid drift.

[0030] S2: As Figure 2 , Figure 4 and Figure 6 As shown, the spray diffusion range is adjusted according to the width of the spraying area (such as the crop row spacing): In the initial state, the four sets of shrink sleeves nest together to form a continuous cone surface, and the atomization range is the largest. If it is necessary to reduce the range, rotate the corresponding shrink sleeve so that the shrink sleeve of the target layer rotates outward and uses its inner wall to block the droplets, thereby limiting the spraying range. During this process, the staggered friction plates 15 can ensure that the actions of each shrink sleeve do not interfere with each other during the adjustment process.

[0031] S3: As Figure 1As shown, after adjustment, inject the prepared fertilizer-pesticide mixture into the storage chamber of the sprayer body 1, ensuring that the liquid level is within the specified range, and assemble the spray gun 3 and the delivery pipe 2;

[0032] S4: As Figure 1 As shown, the sprayer body 1 is then carried on the back, and the power mechanism of the sprayer body 1 (such as a reciprocating manual pressurizing pump) is operated to apply pressure to the fertilizer-pesticide mixture in the storage chamber, so that the pressure in the chamber gradually increases. When the pressure reaches the preset value, the fertilizer-pesticide mixture overcomes the flow resistance under the action of the pressure difference and is stably transported along the conveying pipe 2 to the spray gun 3.

[0033] S5: As Figure 1 and Figure 4 As shown, the operator holds the spray gun 3 in a stable posture, keeping the outlet of the spray gun 3 at a suitable distance from the crop spraying area. The high-pressure fertilizer solution impacts the conical surface of the valve core 14 through the flow channel inside the connector 6, forming a high-speed jet that breaks into droplets in the outer expansion area of ​​the regulating sleeve 7.

[0034] S6: As Figure 6 As shown, after the droplets are sprayed out, they are restricted by the adjusted shrink sleeve, which changes the diffusion range and evenly covers the crop surface or soil area along the preset direction to achieve pesticide and fertilizer spraying.

[0035] The sprayer body 1 and spray gun 3 in this application are known technologies in this field, therefore their specific structures and working principles are not described in detail.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
