Description

Technical Field

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

[0002] As a core piece of equipment in modern agriculture and horticulture plant protection operations, spraying devices atomize pesticides and spray them evenly onto the crop surface to control pests and diseases and maintain crops. With the development of large-scale and intensive agriculture, traditional manual backpack sprayers can no longer meet the operational needs of large-scale farmland and orchards. Mechanized spraying devices have become an inevitable choice to improve operational efficiency and reduce labor costs. These devices can not only improve the uniformity and accuracy of pesticide coverage, but also reduce pesticide waste and environmental pollution, which is of great significance for ensuring crop yields and promoting the development of green agriculture.

[0003] However, existing spraying devices have shortcomings in practical applications. Some devices lack mobility and are difficult to adapt to complex terrains such as mountains and hills, resulting in low operating efficiency. Traditional fixed nozzle designs cannot flexibly adjust the spraying angle and range, easily leading to blind spots or repeated spraying, which affects the control effect and increases pesticide consumption. In addition, the connection structure between the liquid tank and the nozzle of most devices is complex, making disassembly and maintenance inconvenient. Once a malfunction occurs, repairs are time-consuming and labor-intensive. Some devices lack the function of quickly replacing nozzles, making it difficult to meet the diverse needs of different crops and different operating scenarios, thus limiting the versatility and practicality of the equipment. Therefore, we propose a spraying device. Utility Model Content

[0039] High-pressure atomizing nozzle 9: The high-pressure atomizing nozzle 9 is equipped with a second connecting ring 13 at the end, which is connected to the liquid tank 5 through a delivery pipe to atomize the liquid and spray it evenly.

[0040] Fixing plate 10: The fixing plate 10 is connected to the placement plate 18 by bolts, and cooperates with the placement groove to further fix the medicine tank 5 and enhance stability;

[0041] Threaded post 11: The threaded post 11 is located at the bottom of the medicine tank 5, passes through the placement plate 18 and is fixed by a nut to achieve a stable installation of the medicine tank 5;

[0042] First connecting ring 12: The first connecting ring 12 is located at both ends of the liquid tank 5 and cooperates with the second connecting ring 13 of the nozzle to provide a docking structure for nozzle installation;

[0043] Second connecting ring 13: The second connecting ring 13 is located at the end of the high-pressure atomizing nozzle 9 and is in close contact with the first connecting ring 12. It is connected and fixed by the fixing ring 6.

[0046] Connecting shaft 16: The connecting shaft 16 is located at the bottom of the rotating ring 4, and is inserted into the fixing ring to connect with the output shaft of the drive motor 2 to transmit rotational power;

[0047] Upper friction groove 17: The upper friction groove 17 is opened on the bottom end face of the rotating ring 4 and cooperates with the lower friction ring and steel ball 3 of the fixed ring to reduce rotational resistance;

[0048] Placement plate 18: Placement plate 18 is located at the top of rotating ring 4 and is connected by support column. Its placement groove and threaded column 11 are used to fix medicine tank 5.

[0049] Working Principle: In terms of movement and steering, the flexible wheels at the bottom of the device allow for free movement in fields, orchards, and other similar environments. The rotation function relies on the linkage design between the moving base 1 and the rotating ring 4. The drive motor 2 outputs power from the fixed ring at the top of the moving base 1, and its output shaft is fixedly connected to the connecting shaft 16 at the bottom of the rotating ring 4. When the drive motor 2 starts, it drives the connecting shaft 16 to rotate, thus causing the rotating ring 4 to rotate accordingly. To reduce friction during rotation, steel balls 3 are placed between the fixed ring and the bottom of the rotating ring 4. These balls cooperate with the semi-circular lower friction ring at the top of the fixed ring and the upper friction groove 17 on the bottom surface of the rotating ring 4, making the rotation process smoother and achieving 360° flexible steering without dead angles. This facilitates spraying operations with the nozzle aimed in different directions. The storage and transport of the pesticide solution relies on the pesticide tank 5. The pesticide tank 5 passes through the placement plate 18 via a threaded post 11 at the bottom and is then tightened with a nut, securing it firmly on the placement plate 18. Simultaneously, the semi-circular placement grooves at both ends of the placement plate 18 also... The device acts as a limiter, allowing workers to move the liquid tank 5 by the handles and add liquid medicine into the tank using the feed pipe between the handles. The connection between the high-pressure atomizing nozzle 9 and the liquid tank 5 employs a clever quick-disassembly structure. The second connecting ring 13 at the end of the nozzle fits tightly with the first connecting rings 12 at both ends of the liquid tank 5, and a fixing ring 6 is sleeved on the outside. Inside the fixing frame 14 on the fixing ring 6, the compression spring 8 pushes the fixing rod 7, causing its end to insert into the limiting hole on the outer cylindrical surface of the first connecting ring 12 and the second connecting ring 13, firmly fixing the nozzle to the liquid tank 5. When disassembly is required, simply pull the fixing rod 7 upward to overcome the spring force, and it can be easily separated. When the device starts working, the liquid medicine in the liquid tank 5 is transported to the high-pressure atomizing nozzle 9 through the delivery pipe at the end of the nozzle under internal pressure. The nozzle atomizes the liquid medicine into fine particles and sprays them evenly onto the target area. By rotating the rotating ring 4, the spraying direction of the nozzle can be changed. Combined with the movement of the device, a large-area, all-round, and efficient spraying operation can be achieved.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
