Description

Technical Field

[0001] This utility model relates to the field of spray gun technology for agricultural irrigation, and specifically to a spray gun with an adjustable nozzle. Background Technology

[0002] Spray guns are a common piece of equipment in agricultural irrigation. For example, the utility model patent CN218554430U discloses a rotary spray gun with a variable speed structure, including a rotating base, a pipe body, a steering spray pipe, a suspension bracket, a horizontal groove, a steering wheel, a transmission mechanism, a reversing mechanism, and an atomizing water shredder. The spray gun can rotate a certain angle while spraying irrigation. Another utility model patent CN221965771U discloses a spray gun with a power generation and lighting mechanism. This mechanism involves installing a generator and a lighting lamp on the pipe body, and installing a power-generating spray pipe on one side of the pipe body. The inlet of the power-generating spray pipe is connected to the pipe body, and the outlet faces the impeller at the lower end of the generator. Water in the power-generating spray pipe is sprayed onto the impeller to drive its rotation, thus converting water energy into electrical energy to power the lighting lamp, which can be used at night. However, during the day, when the lighting lamp is not needed, the power-generating spray pipe, always facing the impeller at the lower end of the generator, continuously generates electricity, keeping the lighting lamp operational. Therefore, it is necessary to optimize the corresponding structure to improve the applicability of the product. Utility Model Content

[0003] The purpose of this invention is to provide a spray gun with an adjustable nozzle, which solves the problem that existing spray guns cannot be used flexibly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable spray gun includes a main water spray pipe connected to a power generation water spray pipe. The power generation water spray pipe includes a pipe body and a nozzle located at one end of the pipe body. The nozzle and the end of the pipe body are connected by a ball joint, and the nozzle is equipped with an adjustable water breaker.

[0006] Furthermore, the other end of the pipe is rotatably connected to the main water spray pipe.

[0007] Furthermore, the other end of the pipe body is provided with a threaded part, which is threadedly connected to the main water spray pipe, and a sealing gasket and a compression ring are fitted on the threaded part.

[0008] Furthermore, the outer periphery of the clamping ring is provided with a hand-tightening part, and the clamping ring is rotated to clamp the sealing gasket.

[0009] Furthermore, the tube body is an L-shaped tube.

[0010] Furthermore, the nozzle has a spherical connecting part, and the end of the tube body is provided with an external thread and a locking ring is threadedly connected to it; the end of the tube body has a spherical structure that cooperates with the spherical connecting part; the locking ring has a locking part for locking the nozzle after the nozzle angle is adjusted.

[0011] Furthermore, the water shredder includes a screw, and the nozzle has a mounting portion located at the outer edge of the nozzle's spray hole, with the screw threadedly connected to the mounting portion.

[0012] Furthermore, a spring is fitted onto the screw, with both ends of the spring abutting between the mounting portion and one end of the screw.

[0013] Furthermore, the screw is a wing screw.

[0014] Furthermore, the other end of the pipe is connected to the end of the main water spray pipe.

[0015] The beneficial effects of this utility model are:

[0016] By adjusting the angles of the generator-generating water spray pipe and nozzles, the spray direction can be aligned with the generator impeller. The high-pressure water flow drives the impeller to rotate, generating electricity to power the lighting, thus meeting the illumination needs of the spray gun at night. During daytime use, since both the generator-generating water spray pipe and nozzle angles are adjustable, the nozzles can be adjusted to avoid directing water towards the generator impeller. In this case, the nozzles act as secondary nozzles, providing irrigation within a short distance and improving efficiency. The angles of both the generator-generating water spray pipe and nozzles are adjustable, allowing for customization of the irrigation range.

[0017] Furthermore, a water agitator is designed into the nozzle. When used at night, the water spray from the generator spray pipe is used to drive the generator impeller. At this time, the screw of the water agitator is out and does not obstruct the water flow. During the day, when power generation and lighting are not needed, the screw is tightened upwards, and the screw extends and faces the direction of the nozzle's spray, which disperses the water flow and improves the atomization effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0025] Embodiments of this utility model:

[0026] like Figures 1-5 As shown, an adjustable spray gun includes a main water pipe 1 and a rotating base 3. The front end of the main water pipe 1 is provided with a spray nozzle 2. The diameter of the main water pipe 1 is the largest among several spray pipes. The end of the main water pipe 1 has a bend for connecting with the rotating base 3, which is an existing connection method.

[0027] The main water spray pipe 1 is connected to a power generation water spray pipe 4 at its end, and the two are connected internally. For example... Figure 2 As shown, the power generation water spray pipe 4 includes a pipe body 40 and a nozzle 45 located at one end of the pipe body 40. The pipe body 40 is L-shaped. The nozzle 45 is connected to one end of the pipe body 40 by a ball joint, and the angle of the nozzle 45 is adjustable. The other end of the pipe body 40 is rotatably connected to the main water spray pipe 1, and the angle of the pipe body 40 relative to the main water spray pipe 1 is also adjustable.

[0028] A generator and a light are installed in the middle section of the main water spray pipe 1. The structure, principle, and installation method of the generator and light are based on existing technology and are not shown in the figure. By adjusting the angle of the generator-spray pipe 4 and the angle of the nozzle 45, the water spray direction of the nozzle 45 can be ensured to be towards the generator impeller. The high-pressure water flow drives the impeller to rotate, thereby enabling the generator to generate electricity to power the light, meeting the lighting needs of the spray gun at night. When the spray gun is used during the day, since the angles of the generator-spray pipe 4 and the nozzle 45 are both adjustable, the water spray direction of the nozzle 45 can be adjusted to avoid the generator impeller. In this case, the nozzle 45 acts as a secondary nozzle of the spray gun, achieving irrigation within a short range.

[0029] like Figure 2As shown, when the power generation water spray pipe 4 is used as an auxiliary nozzle 45 for irrigation, an adjustable water breaker 5 is provided on the nozzle 45 to improve the atomization effect.

[0030] The water purifier 5 includes a screw 51 and a mounting part 451 at the nozzle 45. The mounting part 451 is located on the outer edge of the water spray hole of the nozzle 45, and the screw 51 is threadedly connected to the mounting part 451. The screw 51 is a wing screw 51, which is easy to tighten by hand; in other embodiments, a bolt may also be used. Figure 3 As shown, the mounting part 451 is a mounting block extending in the water spray direction of the nozzle 45, and has a threaded hole in which the screw 51 is fitted. When used at night, the water spray from the generator water spray pipe 4 is used to drive the generator impeller; at this time, the screw 51 is not pulled out and cannot block the sprayed water flow. During the day, when power generation for lighting is not needed, the screw 51 is tightened upwards, and a portion of the screw 51 extends out of the mounting part 451, facing the water spray direction of the nozzle 45, thus dispersing the water flow and improving the atomization effect.

[0031] A spring 52 is fitted onto the screw 51, with its two ends abutting against the mounting part 451 and one end of the screw 51, respectively. The spring 52 serves two purposes: firstly, it does not affect the adjustment of the screw 51; secondly, after the screw 51 is adjusted, the spring's elasticity helps to prevent the screw 51 from loosening.

[0032] The nozzle 45 has a spherical connecting part, and the end of the tube body 40 is provided with an external thread and a locking ring 43 is threadedly connected to it. The end of the tube body 40 has a spherical structure inside, which cooperates with the spherical connecting part. The spherical cooperation not only allows relative rotation but also provides a sealing function. The locking ring 43 has a locking part inside, which is used to lock the nozzle 45 after the angle is adjusted. It mainly utilizes the clamping force of the locking ring 43. Figure 2 As shown, the outer periphery of the locking ring 43 has two hand-tightening parts, referred to as the first hand-tightening part 431, which makes it easy to rotate the locking ring 43 directly by hand.

[0033] Figure 2 and 3 As shown, the other end of the pipe body 40 is provided with a threaded portion 41, which is threadedly connected to the main water spray pipe 1. A sealing gasket 44 and a clamping ring 42 are fitted on the threaded portion 41. The outer circumference of the clamping ring 42 is provided with a hand-tightening part, referred to as the second hand-tightening part 421. Rotating the clamping ring 42 tightens the sealing gasket 44. This plate-shaped hand-tightening part is integrally provided, so no other tools are needed when tightening the clamping ring 42. After adjusting the angle of the generator water spray pipe 4, the clamping ring 42 can be used to make the sealing gasket 44 fit tightly against one side of the main water spray pipe 1, providing a sealing effect; of course, the threaded connection between the generator water spray pipe 4 and the main water spray pipe 1 also has a certain sealing effect, preventing water leakage.

[0034] The other end of the power generation water spray pipe 4 is connected to the end of the main water spray pipe 1, defined at point A of the main water spray pipe 1, such as... Figure 1 As shown; in other embodiments, mounting holes can also be opened at points B and C on the main water spray pipe 1 for installing the generator water spray pipe 4. In this embodiment, the generator water spray pipe 4 is connected to the end of the main water spray pipe 1 to consider the compact layout. The middle part of the main water spray pipe 1 can be used to install the generator and lighting. If the main water spray pipe is long enough, the generator water spray pipe can be connected at a certain position in the middle of the main water spray pipe.
