Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a multi-functional nozzle. Background Technology

[0002] In the agricultural sector, pesticide spraying is one of the important measures for the prevention and control of crop diseases and pests. Traditional pesticide spraying methods often use nozzles at a fixed height for large-area spraying. This method has some problems. First, due to differences in terrain and crop height, nozzles at a fixed height are difficult to achieve precise spraying, resulting in pesticide waste and environmental pollution. Second, traditional nozzles often have only one outlet, making it difficult to achieve uniform spraying and wide coverage. In addition, traditional spraying methods lack flexibility and cannot meet the spraying needs of different terrains and crops.

[0003] To address these issues, some adjustable-height nozzles and nozzles with multiple outlets have emerged on the market. However, these nozzles still have shortcomings in terms of adjustment accuracy, spray uniformity, and ease of operation. Therefore, we propose a multi-functional nozzle. Utility Model Content

[0017] Example 1

[0018] like Figures 1 to 5As shown, this utility model discloses a multi-functional nozzle. The technical solution includes a sleeve 1 and a three-way pipe 2. The three-way pipe 2 is located at the top of the sleeve 1, and third pipe connectors 11 are located at both ends of the three-way pipe 2. A three-way valve 10 is located at the center of the three-way pipe 2. A connecting female seat 3 is fixedly installed at the top of the three-way pipe 2. A connecting male seat 12 is located above the connecting female seat 3. Bolts in the four corner through holes of the connecting male seat 12 are threadedly connected to the four corner screw holes of the connecting female seat 3. The connecting female seat 3 and the connecting male seat 12 are connected by bolts, thus ensuring that the three-way pipe 2 can be connected to an external frame. A second pipe connector 9 located at the top of the sleeve 1 is threadedly connected to the bottom of the three-way pipe 2. A telescopic unit 4 is located inside the sleeve 1. The telescopic unit 4 includes an inner tube 41, a conical clamping plate 42, a clamping ring 43, an annular sealing piston gasket 44, and a first pipe joint 45. The inner tube 41 is located inside the sleeve 1, and the annular sealing piston gasket 44 at the top of the inner tube 41 is slidably connected to the inner side of the sleeve 1. The first pipe joint 45 at the bottom of the inner tube 41 is threadedly connected to the connecting pipe 6. A clamping ring 43 is movably fitted on the outer side of the inner tube 41. The bottom inner side of the clamping ring 43 has a conical structure, and the bottom inner side of the clamping ring 43 is in active contact with the conical clamping plates 42 arranged in a circular array at equal intervals at the bottom of the sleeve 1. The inner side of the conical clamping plates 42 is in active contact with the outer side of the inner tube 41. By rotating the clamping ring 43 threadedly installed at the bottom of the sleeve 1, the clamping ring 43 moves downward. The conical structure at the bottom of its inner side no longer squeezes the conical clamping plate 42, causing the conical clamping plate 42 to loosen the inner tube 41. At this time, the inner tube 41 can be pulled to slide inside the sleeve 1. The annular sealing piston gasket 44 ensures the sealing during the sliding process. Conversely, if the clamping ring 43 is rotated in the opposite direction, the conical clamping plate 42 will clamp the inner tube 41, thereby controlling the extension and retraction length of the inner tube 41 inside the sleeve 1, achieving the purpose of adjusting the spray distance. The sleeve 1 is connected to the connecting pipe 6 set below the sleeve 1 through the telescopic unit 4. The bottom of the connecting pipe 6 is provided with an adjustment unit 5 and a nozzle assembly. The adjustment unit 5 includes a diversion chamber 51, a connecting frame 52, a diversion baffle 53, an arrow 54, and a knob block 55. The diversion chamber 51 is connected to the bottom of the connecting pipe 6. The diversion chamber 51 is a cylindrical structure. A connecting frame 52 is rotatably mounted at the center of the diversion chamber 51. The middle part of the connecting frame 52 is fixedly connected to a diversion baffle 53 that is slidably mounted inside the diversion chamber 51. Diversion holes are evenly spaced at the bottom of the diversion baffle 53, and the angle between adjacent diversion holes is 40 degrees. The front end of the connecting frame 52 is fixedly connected to an arrow 54 at the front end of the diversion chamber 51, and the rear end of the connecting frame 52 is fixedly connected to a knob block 55 at the rear end of the diversion chamber 51. By rotating the knob block 55, the connecting frame 52 will drive the diversion baffle 53 to rotate inside the diversion chamber 51. The alignment of the diversion holes on the diversion baffle 53 with the diversion pipe 7 determines whether the water flows out through the diversion pipe. The arrow 54 provides a visual indication of the direction of rotation.The engagement of pin 57 and slot 58 is used to fix the position of knob block 55, preventing accidental rotation during spraying. Adjustment unit 5 also includes fixing block 56, pin 57, and slot 58. Fixing block 56 is fixedly installed at the rear top center of the diversion chamber 51. Pin 57 is slidably installed in a sliding hole in the center of fixing block 56. The bottom of pin 57 is movably engaged with slots 58 arranged in a circumferential array at equal intervals around knob block 55. The engagement of pin 57 and slot 58 is used to... The position of the fixed knob block 55 is to prevent accidental rotation during spraying. The nozzle assembly consists of three diversion pipes 7 and adjustable atomizing nozzles 8. The diversion pipes 7 are evenly spaced and connected at the bottom of the diversion chamber 51, with an angle of 40 degrees between adjacent pipes. Each diversion pipe 7 has an adjustable atomizing nozzle 8 at its other end. The water flow is distributed to each adjustable atomizing nozzle 8 through the diversion pipes 7, allowing for further adjustment of the atomization and coverage area.

[0019] The working principle of this utility model is as follows: First, the operation of the multi-functional nozzle begins with the assembly and connection of its overall structure. The sleeve 1 serves as the main support component of the nozzle, and a three-way pipe 2 is fixed to its top via a threaded connection. A three-way valve 10 is set in the center of the three-way pipe 2 to control the direction of water flow. Water can be flexibly selected to flow from the bottom or right end of the three-way pipe 2, or from both directions simultaneously. The left end of the three-way pipe 2 is used to connect to an external water supply pipeline. In addition, a connecting female seat 3 is fixedly installed on the top of the three-way pipe 2, and a connecting male seat 12 and bolts are used to connect the two parts. The coordination ensures that the three-way pipe 2 can be securely connected to the external frame. Then, when the height of the multi-functional nozzle needs to be adjusted to adapt to different spraying requirements, the clamping ring 43, which is threadedly installed at the bottom of the sleeve 1, is rotated to move the clamping ring 43 downward. The conical structure at its inner bottom no longer squeezes the conical clamping plate 42, causing the conical clamping plate 42 to loosen the inner tube 41. At this time, the inner tube 41 can be pulled to slide inside the sleeve 1. The annular sealing piston gasket 44 ensures the sealing during the sliding process. Conversely, rotating the clamping ring 43 in the opposite direction will cause the conical... The clamping plate 42 clamps the inner tube 41, thereby controlling the extension and retraction length of the inner tube 41 within the sleeve 1 to adjust the spray distance. Secondly, the adjusting unit 5 controls whether water flows from the nozzle at the end of the diversion pipe 7. By rotating the knob block 55, the connecting bracket 52 drives the diversion baffle 53 to rotate within the diversion chamber 51. The alignment of the diversion hole on the diversion baffle 53 with the diversion pipe 7 determines whether water flows out through the diversion pipe. The arrow 54 provides a visual indication of the rotation direction, while the engagement of the pin 57 and the slot 58 is used to fix the knob block 5. Position 5 prevents accidental rotation during spraying. Then, after the water flows through the regulating unit 5 into the diversion pipe 7, it will flow further to the adjustable atomizing nozzle 8. The adjustable atomizing nozzle 8 can adjust the atomization and coverage range of the spray as needed to ensure that the pesticide can be sprayed evenly on the target area. There are three diversion pipes 7, which are connected at equal distances at the bottom of the diversion chamber 51, and the angle between adjacent diversion pipes 7 is 40 degrees, forming a 120-degree spray range between the diversion pipes 7, thereby ensuring the uniformity of spraying and the coverage area.
