Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a spraying device. Background Technology
[0002] Spraying devices are widely used as key agricultural and industrial equipment. In agriculture, they are used for precise application of pesticides and fertilizers, affecting crop growth and yield. In landscaping, they are responsible for plant irrigation and pest and disease control, contributing to landscape creation. In industry, they play an important role in processes such as dust removal, coating, and cooling.
[0003] However, most spraying devices currently on the market have many shortcomings in practical applications: First, they lack flexibility in adjusting the spray angle and coverage area. Some devices have fixed spray angles and coverage ranges at the factory, making it difficult to adapt to complex and changing working environments, resulting in poor spray accuracy and incomplete coverage during spraying operations. Second, they have poor atomization uniformity, which easily leads to uneven liquid spraying, wasting liquid resources and failing to achieve the expected working effect. Summary of the Invention
[0004] To address the above problems, this application provides a spraying device, including a support platform, a water pump, an engine, a propeller, a protective frame, and a spray atomizing ring. The engine and the propeller are mounted on the support platform and located inside the protective frame. The spray atomizing ring is fixed to the front end of the protective frame and connected to the water pump via a pipe.

[0026] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0027] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0028] like Figure 1-4 As shown, a spraying device includes a support platform 1, a water pump 2, an engine 3, a propeller 4, a protective frame 5, and a spray atomizing ring 6. The engine 3 and the propeller 4 are mounted on the support platform 1 and located inside the protective frame 5. The spray atomizing ring 6 is fixed to the front end of the protective frame 5 and is connected to the water pump 2 through a pipe. Atomizing holes 61 are evenly distributed around the periphery of the spray atomizing ring 6. At least one guide plate 7 is provided between the propeller 4 and the spray atomizing ring 6. The guide plate 7 is rotatably mounted on the protective frame 5 and is used to adjust the airflow path by changing the deflection direction.
[0029] Specifically, the support platform 1 is the basic load-bearing structure of the entire spraying device. A reducer is installed between the engine 3 and the propeller 4. The engine 3, as the power output mechanism, drives the propeller 4 to rotate. The protective frame 5 is installed on the support platform 1, enclosing the engine 3 and propeller 4 inside, providing protection against external collisions and debris. The spray atomizing ring 6 is fixed at the front end of the protective frame 5 and connected to the water pump 2 through a pipe. The water pump 2 delivers liquid into the spray atomizing ring 6. A guide plate 7 is rotatably installed between the propeller 4 and the spray atomizing ring 6. The upper and lower ends of the guide plate 7 are mounted on the protective frame 5 via bearings. The deflection angle of the guide plate 7 is adjustable to change the airflow direction. When the spraying device starts working, the engine 3 starts running, driving the propeller 4 to rotate at high speed. The rotation of the propeller 4 generates a strong airflow, which flows from the propeller 4 towards the spray atomizing ring 6. Simultaneously, water pump 2 starts working, drawing liquid from the storage container and delivering it through connected pipes to the spray atomizing ring 6. After entering the spray atomizing ring 6, the liquid is sprayed out in a mist form from the evenly distributed atomizing holes 61 around its perimeter. The operator can adjust the deflection direction of the guide plate 7 according to actual spraying needs. The deflection of the guide plate 7 alters the flow path of the airflow generated by the propeller 4, causing the airflow to flow in a specific direction and range, thereby guiding the mist-like liquid sprayed from the atomizing holes 61 accurately to the area requiring spraying. In this application, by setting a rotatable guide plate 7, the deflection direction is adjusted to change the airflow path, which can flexibly adjust the spray angle and coverage of the atomized liquid according to actual needs, thereby improving the accuracy and adaptability of spraying, avoiding liquid waste, and improving resource utilization efficiency. The spray atomizing ring 6 is connected to the water pump 2 through a pipeline, which ensures that the liquid can be smoothly delivered to the spraying part, and the uniform distribution of the atomizing holes 61 enables the liquid to be atomized and sprayed evenly, thereby improving the uniformity of spraying.
[0030] like Figure 4 , 5 As shown, there are two guide plates 7, which are symmetrically arranged. A linkage rod 71 is provided between the two guide plates 7. The two ends of the linkage rod 71 are hinged to the guide plates 7, and the middle part of the linkage rod 71 is hinged to the pull rod 72. Pulling the pull rod 72 can drive the linkage rod 71 to move back and forth, thereby adjusting the deflection angle of the guide plate 7.
[0031] Specifically, the two ends of the linkage rod 71 are connected to the guide plate 7 via fisheye bearings, and the linkage rod 71 is connected to the pull rod 72 via fisheye bearings. Through the connection of the linkage rod 71, the two guide plates 7 can maintain a consistent deflection angle during rotation. The operator can precisely adjust the deflection angle of the guide plate 7 by pulling the pull rod 72, thereby achieving precise control of the spray range and direction of the mist liquid. The operation method is simple and intuitive.
[0032] like Figure 2 As shown, a guide ring is provided between the propeller 4 and the guide plate 7. The inner wall of the guide ring is a tapered curved surface, which is used to accelerate and rectify the airflow generated by the propeller 4.
[0033] Specifically, the tapered inner wall of the guide ring (not shown in the figure) guides the airflow to converge, achieving an acceleration effect. Simultaneously, the tapered curved surface structure straightens turbulent airflow, allowing it to flow more smoothly and orderly towards the guide plate 7, thereby increasing the liquid's diffusion range and uniformity, and enhancing the spraying effect. The inner wall surface of the guide ring is coated with a hydrophobic nano-coating, which allows liquid to quickly slide off upon contact, keeping the inner wall of the guide ring clean and ensuring stable and efficient airflow.
[0034] like Figure 5 As shown, a flow regulating valve 8 is installed on the pipeline between the water pump 2 and the spray atomizing ring 6. The flow regulating valve 8 is an electric regulating valve that regulates the flow rate of liquid entering the spray atomizing ring 6.
[0035] Specifically, the flow rate of liquid entering the spray atomizing ring 6 can be precisely controlled by the electric regulating valve 8, and the spray volume can be adjusted in real time according to the operation requirements to ensure that the best spraying effect can be obtained in different operation scenarios such as pesticide spraying and disinfection operations.
[0036] like Figure 1 As shown, the protective frame 5 is provided with a detachable protective net.
[0037] Specifically, the protective net (not shown in the figure) can effectively block foreign objects such as flying stones and branches from entering the interior of the protective frame 5, and prevent the propeller 4 and engine 3 from being damaged by accidental impact.
[0038] This application discloses a spraying device, including a support platform 1, a water pump 2, an engine 3, a propeller 4, a protective frame 5, and a spray atomizing ring 6. The spray atomizing ring 6 is fixed to the front end of the protective frame 5 and connected to the water pump 2 via a pipe. Atomizing holes 61 are evenly distributed around the periphery of the spray atomizing ring 6. At least one guide plate 7 is provided between the propeller 4 and the spray atomizing ring 6. The guide plate 7 is rotatably mounted on the protective frame 5 and is used to adjust the airflow path by changing the deflection direction. When the spraying device starts working, the engine 3 starts running, driving the propeller 4 to rotate at high speed, and the airflow flows from the propeller 4 towards the spray atomizing ring 6. At the same time, the water pump 2 starts working, delivering liquid to the spray atomizing ring 6 through the connected pipe. After entering the spray atomizing ring 6, the liquid is sprayed out in a mist form from the evenly distributed atomizing holes 61 around its periphery. Operators can adjust the deflection direction of the guide plate 7 according to actual spraying needs. The deflection of the guide plate 7 can change the flow path of the airflow generated by the propeller 4, causing the airflow to flow in a specific direction and range, thereby driving the atomized liquid sprayed from the atomizing holes 61 and accurately guiding it to the area to be sprayed. In this application, by setting a rotatable guide plate 7 and adjusting the deflection direction to change the airflow path, the spray angle and coverage of the atomized liquid can be flexibly adjusted according to actual needs, improving the accuracy and adaptability of spraying, avoiding liquid waste, and improving resource utilization efficiency. The spray atomizing ring 6 is connected to the water pump 2 through a pipeline, ensuring that the liquid can be smoothly delivered to the spraying site, and the uniform distribution of the atomizing holes 61 allows the liquid to be evenly atomized and sprayed, improving the uniformity of spraying.
