Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation technology, specifically to a spraying device. Background Technology

[0002] In agriculture, landscaping, and lawn maintenance, spraying devices are commonly used equipment for spraying water mist or pesticides. The spraying device uses nozzles to evenly spray water mist onto the covered area to achieve the purpose of spraying, thereby realizing the effective allocation and utilization of water resources.

[0003] Although various spraying devices exist in the existing technology, their working methods are relatively simple. They usually achieve irrigation coverage by rotating the nozzle, resulting in low irrigation efficiency. The rotating parts are also prone to wear and tear, requiring regular replacement and maintenance.

[0004] In practical applications, the range and height of spray irrigation largely depend on the water pressure. When used in situations requiring a certain irrigation height, the water pressure needs to be increased further. Increasing the water pressure not only increases energy consumption but also requires ensuring the pressure resistance of the entire spray device, resulting in higher costs. Summary of the Invention

[0005] This invention addresses the problems of existing spray devices that rely on rotation to cover the irrigation area, resulting in high operating costs due to wear of rotating components, and the difficulty in simultaneously ensuring both spray range and height when a certain watering height is required. It provides a spray device that eliminates the need for rotation to cover the irrigation area while simultaneously ensuring both spray range and height, thus improving irrigation efficiency.

[0006] To solve the above problems, the technical solution of this utility model is:

[0007] A spraying device includes a spraying assembly and a blowing assembly. The spraying assembly includes a nozzle, a spraying frame, and a water pipe. At least one nozzle is disposed on the spraying frame, and the water pipe is connected to the nozzle and provides a water source to the nozzle.

[0008] The nozzle is located at the front end of the spray frame, and the air blowing assembly is located at the rear end of the spray frame;

[0009] The blowing assembly is used to spread the water mist sprayed from the nozzle in all directions.

[0010] By adopting the above solution, the water mist sprayed from the nozzle can be diffused to a larger area by the blowing component, thereby effectively improving the spray range and height of the nozzle, and the blowing component can evenly disperse the water mist, making the spray more uniform.

[0011] Based on the above solution, the present invention can be further improved as follows.

[0012] Furthermore, the nozzle is located at the edge of the spray frame, and the nozzle outlet faces outward.

[0013] By adopting the above-mentioned further solution, since the nozzles are distributed on the edge of the spray frame, the water mist can be more quickly and evenly distributed to the entire area under the action of the blowing component.

[0014] Furthermore, the spraying device also includes a baffle;

[0015] The baffle is fixedly connected to the spray frame, and the nozzle is disposed between the spray frame and the baffle. The baffle is used to direct the airflow generated by the blowing assembly toward the nozzle.

[0016] By adopting the above-mentioned further solution, the baffle not only ensures that the airflow is directed towards the nozzle, thereby ensuring the diffusion effect of the water mist, but also prevents backwind from affecting the airflow generated by the blowing component, ensuring that even in windy environments, the airflow generated by the blowing component can still be directed towards the nozzle stably.

[0017] Furthermore, the spray frame includes a first spray support plate, a second spray support plate, and a support plate connector in the shape of a pipe. The first spray support plate and the second spray support plate are respectively fixedly disposed on the outer circular surfaces at both ends of the support plate connector.

[0018] The blower assembly includes a power unit, a drive shaft, and fan blades. One end of the drive shaft is fixedly connected to the power unit, and the other end is fixedly connected to the fan blades. The fan blades are disposed inside the support plate connector.

[0019] With the above-mentioned further solution, the first spray support plate and the second spray support plate are fixed at both ends of the support plate connector, forming a stable tubular structure, which increases the stability of the overall device; the fan blades are located inside the support plate connector, which can make the airflow blow more effectively toward the nozzle.

[0020] Furthermore, the spraying device also includes a baffle and a screen;

[0021] There is a gap between the baffle and the first spray support plate and the two are fixedly connected. The nozzle is disposed between the first spray support plate and the baffle. The partition is fixedly disposed on the second spray support plate.

[0022] Furthermore, the mesh is a mesh structure;

[0023] Alternatively, the mesh can be a mesh structure composed of one or more ring rods and strip rods. When there are multiple ring rods, the multiple ring rods have different diameters and are concentrically fixed on the strip rods. By fixing ring rods of different diameters, the mesh size can be adjusted to block debris of different sizes to adapt to different usage environments. The strip rods are fixedly connected to the second spray support plate.

[0024] The mesh has holes in the middle that allow the drive shaft to pass through.

[0025] Furthermore, at least one of the nozzles is disposed at the edge of the first spray support plate, and the nozzles are disposed circumferentially or non-circumferentially, uniformly or non-uniformly on the first spray support plate.

[0026] When the spray pattern is not circumferential, a protective plate is provided between the first spray support plate and the baffle.

[0027] By adopting the above-mentioned further solutions, uniformly distributed nozzles can ensure that the entire area receives uniform water coverage, while non-uniformly distributed nozzles can be customized according to crop growth needs or terrain characteristics to optimize water resource utilization. At the same time, when the first sprinkler support plate is placed vertically to the ground, the protective plate can prevent the high-pressure water mist sprayed from the nozzles from damaging the green plants at the bottom of the sprinkler frame, prevent soil splashed from the ground from entering the interior of the sprinkler frame, and prevent the airflow generated by the blower assembly from escaping from the bottom of the sprinkler frame, thus affecting the diffusion effect of the water mist.

[0028] Furthermore, the water pipe is connected to the nozzle via a connector, and the number of connectors is the same as the number of nozzles.

[0029] Furthermore, the support plate connector is a tube with a geometric shape such as a cylinder, cube, or triangular prism; the power device is an electric motor.

[0030] Furthermore, the baffle is a flat baffle or a curved baffle, and the center of the curved baffle is recessed towards the first spray support plate or protrudes towards the first spray support plate.

[0031] With the above-mentioned further solution, when the baffle is a flat baffle, after the airflow hits the baffle, it will blow towards the nozzle along the spray direction of the nozzle, thereby more effectively blowing the water mist to all sides and expanding the spray range and height of the nozzle; when the baffle is a curved baffle, after the airflow hits the baffle, the gas flow direction will be at a certain angle to the spray direction of the nozzle, thereby more effectively dispersing the water mist and improving the uniformity of the nozzle spray.

[0032] The beneficial effects of this utility model through the above technical solution are as follows:

[0033] 1. In this utility model, the blowing component can blow the water mist sprayed from the nozzle to all directions and disperse the water mist, which can not only increase the spray range and height of the nozzle, but also improve the uniformity of the spray.

[0034] 2. In this utility model, the baffle can direct the airflow generated by the blower assembly toward the nozzle, thereby ensuring the effect of water mist spreading in all directions; and the mesh can prevent debris from entering the spray frame when the blower assembly is working, which not only prevents the fan blades from being damaged, but also prevents debris from obstructing the airflow toward the nozzle, further ensuring the effect of water mist diffusion.

[0035] 3. In this utility model, the nozzles can be evenly or non-uniformly arranged on the first spray support plate according to actual needs, thus expanding the applicable scenarios of the spray device. Attached Figure Description

[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0043] like Figures 1 to 5 As shown, a spraying device includes a spraying assembly and a blowing assembly 4.

[0044] The spray assembly includes a nozzle 1, a spray frame 2, and a water pipe 3. The spray frame 2 is a structure with open ends and a hollow interior. At least one nozzle 1 is provided on the spray frame 2. The water pipe 3 is connected to the nozzle 1 and provides a water source for the nozzle 1. Specifically, different numbers of water pipes 3 can be selected to connect to an external power sprayer to provide a water source for the nozzle 1, depending on the number of nozzles 1 or the required water pressure.

[0045] In this embodiment, the external connector of water pipe 3 is a TKC-80 type iron beetle power sprayer.

[0046] The nozzle 1 is located at the front end of the spray frame 2, and the air blowing assembly 4 is located at the rear end of the spray frame 2.

[0047] The blowing component 4 is used to spread the water mist sprayed from the nozzle 1 in all directions, thereby effectively increasing the spray range and height of the nozzle 1. The blowing component 4 can also evenly disperse the water mist, making the spraying more uniform.

[0048] In one possible implementation, the nozzle 1 is disposed around the center of the spray frame 2 at the edge of the spray frame 2, and the nozzle 1 spray outlet faces outward.

[0049] As one possible implementation, the spraying device further includes a baffle 5 and a partition net 7;

[0050] The baffle 5 is fixedly connected to the spray frame 2 by fasteners 6, and the nozzle 1 is disposed between the spray frame 2 and the baffle 5. The baffle 5 is used to direct the airflow generated by the blower assembly 4 toward the nozzle 1, and can also prevent back wind from affecting the airflow generated by the blower assembly 4, ensuring that even in a windy environment, the airflow generated by the blower assembly 4 can still be stably directed toward the nozzle 1.

[0051] The partition net 7 is fixedly installed at the rear end of the spray frame 2 and is located at the same end of the spray frame 2 as the blower assembly 4, and is used to prevent debris from entering the interior of the spray frame 2 when the blower assembly 4 blows air.

[0052] As one possible implementation, the spray frame 2 includes a first spray support plate 21, a second spray support plate 22, and a support plate connector 23 in the shape of a pipe. The first spray support plate 21 and the second spray support plate 22 are respectively fixedly arranged on the outer circular surfaces at both ends of the support plate connector 23, forming a stable tubular structure and increasing the stability of the overall device.

[0053] The blowing assembly 4 includes a power unit 41, a drive shaft 42, and a fan blade 43. One end of the drive shaft 42 is fixedly connected to the power unit 41, and the other end is fixedly connected to the fan blade 43. The fan blade 43 is disposed inside the support plate connector 23, which can more effectively blow the airflow toward the nozzle 1. Furthermore, since the debris-blocking net 7 can prevent debris from entering the spray frame 2, the fan blade 43 is not easily damaged. The driving unit 41 is a motor.

[0054] The power unit 41 can be supported by a support frame between it and the support plate connector 23, or by fixing the power unit 41 and the spray frame 2 to external equipment respectively. In this embodiment, the power unit 41, i.e., the motor, and the spray frame 2 are fixedly installed at the rear of the spraying vehicle.

[0055] As one possible implementation, the spraying device further includes a baffle 5 and a partition net 7;

[0056] There is a gap between the baffle 5 and the first spray support plate 21 and the two are fixedly connected by fasteners 6. The nozzle 1 is set between the first spray support plate 21 and the baffle 5. The partition 7 is fixedly set on the second spray support plate 22 to block debris from entering the spray frame 2.

[0057] As one possible implementation, the partition 7 has a mesh structure;

[0058] Alternatively, the mesh 7 can be a mesh structure composed of one or more ring rods 71 ​​and strip rods 72. When there are multiple ring rods 71, the multiple ring rods 71 ​​have different diameters and are concentrically fixed on the strip rods 72. By fixing ring rods 71 ​​of different diameters, the mesh size can be adjusted to block debris of different sizes to adapt to different usage environments. The strip rods 72 are fixedly connected to the second spray support plate 22. In this embodiment, the strip rods 72 are fixedly connected to the spray frame 2 by bolts and nuts, which is convenient for disassembly and assembly.

[0059] The mesh 7 has mesh holes 73 in the middle that allow the drive shaft 42 to pass through.

[0060] As one possible implementation, at least one of the nozzles 1 is disposed at the edge of the first spray support plate 21, and the nozzles 1 are disposed circumferentially or non-circumferentially, uniformly or non-uniformly on the first spray support plate 21.

[0061] In this embodiment, the first spray support plate 21 is placed vertically to the ground. No nozzle 1 is provided at the bottom of the first spray support plate 21, and a protective plate 8 is provided between the bottom of the first spray support plate 21 and the bottom of the baffle 5. This prevents the high-pressure water mist sprayed from the nozzle 1 from damaging the green plants at the bottom of the spray frame 2 and prevents the soil splashed from the ground from entering the interior of the spray frame 2. At the same time, it prevents the airflow generated by the blower assembly 4 from escaping from the bottom of the spray frame 2 and affecting the diffusion effect of the water mist.

[0062] In one possible implementation, the water pipe 3 is connected to the nozzle 1 via a connector 31, and the number of connectors 31 is the same as the number of nozzles 1.

[0063] As one possible implementation, the support plate connector 23 is a cylindrical, cubic, or triangular prism-shaped tube. In this embodiment, the support plate connector 23 is a cylindrical tube; the power device 41 is a motor.

[0064] As one possible implementation, the baffle 5 is a flat baffle or a curved baffle. The center of the curved baffle is concave towards the first spray support plate 21 or convex away from the first spray support plate 21. When the baffle 5 is a flat baffle, after the airflow hits the baffle 5, it will blow towards the nozzle along the spraying direction of the nozzle 1, thereby more effectively blowing the water mist to the surroundings and expanding the spraying range and height of the nozzle 1. When the baffle 5 is a curved baffle, after the airflow hits the baffle 5, the gas flow direction will be at a certain angle to the spraying direction of the nozzle 1, thereby more effectively dispersing the water mist and improving the uniformity of the spray from the nozzle 1.

[0065] In this embodiment, the first spray support plate 21, the second spray support plate 22 and the baffle 5 are circular planar support plates arranged in parallel to each other, and the centers of the circles are all located on the same axis; the second spray support plate 22 and the baffle 5 are the same size.

[0066] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
