Description

Technical Field

[0001] This utility model relates to the field of liquid spray nozzle technology, and more specifically, to a spray nozzle assembly that is easy to adjust. Background Technology

[0002] When spraying pesticides on crops, people usually need to use a sprayer. The sprayer delivers the pesticide solution to the nozzle through an infusion hose, and then the nozzle sprays it onto the crops. Usually, the nozzle needs to be installed on a fixed rod. Currently, the clamps that fix the nozzle to the fixed rod are fixed and cannot be adjusted. As a result, the nozzle can only be fixed on a fixed rod of a specific diameter. Different sizes of clamps need to be replaced for fixed rods of different diameters, which is very inconvenient to use. Therefore, overcoming the defects of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0003] This invention provides a conveniently adjustable nozzle assembly, aiming to improve the current situation where the clamps that fix the nozzle to the fixing rod are fixed and cannot be adjusted. As a result, the nozzle can only be fixed to the fixing rod of a specific diameter, and different sizes of clamps need to be replaced for fixing rods of different diameters, which is very inconvenient to use.

[0004] To achieve the above objectives, this utility model provides a nozzle assembly that is easy to adjust, and the specific technical solution is as follows:

[0005] An easily adjustable nozzle assembly includes a spray tube with a nozzle at one end and infusion tubes connected to both sides of the spray tube. An adjustment mechanism is provided at the end of the spray tube away from the nozzle, which allows the spray tube to be mounted on fixed rods of different diameters. The adjustment mechanism includes a mounting base fixed to the end of the spray tube away from the nozzle. A clamping sleeve is fitted onto the mounting base, with the openings at both ends of the clamping sleeve slidably staggered. A driving component is provided between the mounting base and the clamping sleeve, and the driving component is kinetically connected to the clamping sleeve.

[0006] Rotating the drive component causes one end of the clamping sleeve to slide relative to the other end, which in turn changes the staggered position of the two ends of the clamping sleeve, thereby changing the diameter of the clamping sleeve. As a result, the clamping sleeve can be clamped onto fixed rods of different diameters.

[0007] In one embodiment, a valve is provided on the spray pipe, and the valve is located between the nozzle and the infusion pipe.

[0008] In one embodiment, limiting plates are provided on both sides of the mounting base, and the driving component is engaged with the mounting base by the two limiting plates.

[0009] In one embodiment, the driving component includes a connecting shaft disposed on the outside of the limiting plate. One end of the connecting shaft is provided with a rotating shaft, which is disposed between two limiting plates and rotatably connected to the two limiting plates. The rotating shaft is provided with a driving thread, and the clamping sleeve is uniformly provided with a plurality of through holes that mate with the driving thread. The distance between two adjacent through holes is equal to the pitch of the driving thread. By rotating the driving thread, the driving thread can drive the two ends of the clamping sleeve to change their staggered positions through the through holes, thereby changing the diameter of the clamping sleeve. Thus, the clamping sleeve can clamp onto fixed rods of different diameters.

[0010] In one embodiment, a knob is fixed at the end of the connecting shaft away from the rotating shaft, and rotating the knob can drive the driving component to rotate.

[0011] The beneficial effects of this embodiment are:

[0012] By setting an adjustment mechanism at one end of the spray pipe, when the diameter of the clamping sleeve needs to be adjusted, the drive component is rotated, and the moving thread on the drive component can drive the two ends of the clamping sleeve to change their staggered positions through the through hole, thereby changing the diameter of the clamping sleeve. Thus, the clamping sleeve can be clamped on fixed rods of different diameters. The whole device has a simple structure and is easy to operate. It can adjust the diameter of the clamping sleeve according to the fixed rod of different sizes to adapt to the fixed rod, greatly improving its mobility and flexibility. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] Please see Figure 1-6 This utility model provides a conveniently adjustable spray head assembly, including a spray pipe 100, with a nozzle 110 at one end of the spray pipe 100. The nozzle 110 is used to spray the pesticide solution onto the crops. Infusion pipes 200 are connected to both sides of the spray pipe 100. The infusion pipe 200 has threads, which can be used to fix and connect an infusion hose with a connector. The infusion hose delivers the pesticide solution from the sprayer to the infusion pipe 200, and then the infusion pipe 200 delivers the pesticide solution to the nozzle 110, which then sprays it out. A valve 120 is provided on the spray pipe 100, positioned between the nozzle 110 and the infusion pipe 200. The valve 120 controls the opening and closing of the nozzle 110 and the spray size, making it convenient to use.

[0028] An adjustment mechanism 300 is provided at the end of the spray pipe 100 away from the nozzle 110. The adjustment mechanism 300 can be used to install the spray pipe 100 on fixed rods 400 of different diameters. Specifically, the adjustment mechanism 300 includes a mounting base 310, which is fixed to the end of the spray pipe 100 away from the nozzle 110 by welding. A clamping sleeve 320 is sleeved on the mounting base 310. The clamping sleeve 320 is a spring with a certain elasticity. The two ends of the clamping sleeve 320 are alternately slidably arranged. A driving member 330 is provided between the mounting base 310 and the clamping sleeve 320. The driving member 330 is connected to one end of the clamping sleeve 320 in a transmission connection.

[0029] It should be noted that the mounting base 310 has integrally formed limit plates 311 on both sides. The driving component 330 is snapped onto the mounting base 310 through the two limit plates 311. The driving component 330 includes a connecting shaft 331, which is located on the outside of the limit plates 311. One end of the connecting shaft 331 is provided with a rotating shaft 332, which is located between the two limit plates 311. The rotating shaft 332 is rotatably connected to the two limit plates 311. A knob 334 is fixed at the end of the connecting shaft 331 away from the rotating shaft 332. Rotating the knob 334 can drive the rotating shaft 332 to rotate.

[0030] The rotating shaft 332 is provided with a driving thread 333, and the clamping sleeve 320 is provided with a plurality of through holes 321 that mate with the driving thread 333. The distance between two adjacent through holes 321 is equal to the pitch of the driving thread 333. A portion of the driving thread 333 is embedded in the through hole 321. By manually rotating the rotating shaft 332 through the knob 334, the rotating shaft 332 drives the driving thread 333 to rotate around its axis. The rotation of the driving thread 333 can drive the staggered position of the two ends of the clamping sleeve 320 to change through the through holes 321. When the overlapping portion at both ends of clamping sleeve 320 becomes longer, the ends of clamping sleeve 320 retract inward, and the diameter of clamping sleeve 320 becomes smaller. Conversely, when the overlapping portion at both ends of clamping sleeve 320 becomes shorter, the ends of clamping sleeve 320 expand outward, and the diameter of clamping sleeve 320 becomes larger. Thus, the diameter of clamping sleeve 320 can be adjusted in real time according to the thickness of fixing rod 400, so that clamping sleeve 320 can be clamped and fixed on fixing rod 400 of different diameters, which facilitates the installation and fixation of nozzle 110 and greatly improves the mobility and flexibility of nozzle 110 installation.
