Description

Technical Field

[0001] This application relates to the field of agricultural spraying equipment technology, and in particular to a fog cannon nozzle and a sprayer. Background Technology

[0002] A sprayer is short for spraying equipment. It's a device that uses air suction to turn pesticides or other liquids into a mist, which is then sprayed evenly onto other objects. It consists of a compressed air device, a thin tube, and nozzles. In agricultural production, sprayers are indispensable agricultural tools for controlling pests and diseases.

[0003] The mist cannon nozzle is a crucial component of a sprayer, primarily consisting of a sleeve, a rotating cup, a rotating water outlet rod, a fan, and a mounting base. The mounting base is fixed inside the sleeve, with a gap between them for air intake. The mounting base has a water inlet pipe. The rotating water outlet rod is rotatably connected to the mounting base and is a hollow tube. One end of the rotating water outlet rod is sealed to the water inlet pipe, while the other end has a water outlet hole on its side wall and a rotating cup is fixedly fitted thereon. A gap between the rotating cup and the sleeve for air outlet is provided. A fan is fixedly fitted onto the rotating water outlet rod. During use, external wind drives the fan to rotate at high speed, which in turn drives the rotating water outlet rod and the rotating cup to rotate at high speed. Water flows through the water inlet pipe into the rotating water outlet rod and is sprayed out at high speed from the outlet hole. After impacting the rotating cup, the water is torn and atomized, forming mist droplets. External wind, through the fan, blows out the sheared droplets through the gap between the rotating cup and the sleeve, causing secondary atomization and simultaneously blowing out the water mist. This results in small droplets, a long range, wide coverage, and high efficiency with low pesticide consumption, making it suitable for pesticide spraying of crops and plant protection in gardens.

[0004] However, in practice, the structure of this mist cannon nozzle is quite complex. On the one hand, during the installation of the rotating water outlet rod and the rotating cup, they must be coaxially connected, meaning their center lines must coincide. The precision requirements for component installation are extremely strict. Furthermore, the rod-shaped structure of the water outlet rod and the cylindrical shape of the rotating cup significantly increase the installation difficulty. On the other hand, after the rotating water outlet rod and the rotating cup are coaxially installed, the overall structure is slender. During use, the water outlet rod and the rotating cup rotate synchronously at high speed, inevitably causing vibration and shortening their service life. When the rotating water outlet rod and the rotating cup are not installed coaxially as required, or when they rotate at high speed during use, vibration is unavoidable, preventing the mist cannon nozzle from forming a large spray area, resulting in uneven pesticide application and hindering large-area, rapid pesticide control. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing a fog cannon nozzle and sprayer that enables the fog cannon nozzle to continuously and stably generate a large-area spray, ensuring uniform pesticide application and enabling rapid pesticide control over a large area.

[0006] Therefore, this utility model provides a fog cannon nozzle, which includes a nozzle housing, a nozzle, a nozzle rod, a turbine fan blade, and a support connecting rod. The nozzle housing is a cylindrical structure, which contains the nozzle, nozzle rod, turbine fan blade, and support connecting rod. The support connecting rod is fixed inside the nozzle housing and has an air inlet channel and a first liquid inlet pipe. The nozzle rod passes through the bottom of the nozzle and the center hole of the turbine fan blade from front to back and is connected to the support connecting rod. The nozzle rod has a second liquid inlet pipe, which is sealed and connected to the first liquid inlet pipe. The spray port of the second liquid inlet pipe faces the inner wall of the nozzle. The nozzle is a cup-shaped structure with a hollow bottom and the nozzle opening faces forward. There is a gap between the nozzle and the nozzle housing, which is connected to the air inlet channel. The bottom of the nozzle is fixedly connected to the side wall of the turbine fan blade. The nozzle rod passes through the bottom of the nozzle and the center hole of the turbine fan blade from front to back and is fixedly connected to the support connecting rod. The nozzle and the nozzle rod are spaced apart from each other, and the turbine fan blade is rotatably connected to the nozzle rod.

[0007] Preferably, the support connecting rod is detachably and fixedly connected to the nozzle housing by screws, and an air inlet channel is formed between the support connecting rod and the nozzle housing.

[0008] Preferably, the nozzle rod passes through the bottom of the nozzle and the center hole of the turbine blade from front to back and is detachably fixed to the support connecting rod by threads.

[0010] Preferably, the second liquid inlet pipe has multiple spray nozzles, which are evenly distributed along the circumferential direction of the nozzle head.

[0011] Preferably, the gap is an annular gap.

[0012] This utility model also provides a sprayer, including the fog cannon nozzle of any of the above.

[0013] Preferably, the sprayer further includes a sprayer housing, an air supply device, and a liquid delivery device. The sprayer housing is detachably and sealedly fixedly connected to the mist cannon nozzle. The air supply device is equipped with a fan, which is installed inside the sprayer housing. The sprayer housing has an air inlet hole. Inside the sprayer housing, the fan and the sprayer housing with the air inlet hole form an air inlet chamber, and the fan and the sprayer housing connected to the mist cannon nozzle form an air outlet chamber. The air inlet hole is connected to the air inlet of the fan through the air inlet chamber, and the air outlet of the fan is connected to the air inlet channel of the mist cannon nozzle through the air outlet chamber. The liquid delivery device is equipped with a liquid inlet pipe, which is installed inside the sprayer housing. The sprayer housing is equipped with a liquid inlet external interface. The liquid inlet port of the liquid inlet pipe is sealed and connected to the liquid inlet external interface, and the liquid outlet port of the liquid inlet pipe is sealed and connected to the first liquid inlet pipe of the mist cannon nozzle.

[0014] Preferably, the sprayer housing is also equipped with a power connection port and a power switch. The power connection port is electrically connected to the power cord of the blower, and the power switch is electrically connected to the power cord of the blower. The power cord of the blower is located inside the sprayer housing.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a fog cannon nozzle and sprayer with a simpler structure.

The pesticide sprayed from the spray nozzle of the nozzle rod is subjected to rotational centrifugal force and air shear force to form fine droplets that diffuse in all directions, achieving rapid spraying over a large area. It is suitable for pesticide spraying of crops, garden plant protection, and other scenarios. Compared with the prior art, since the nozzle rod is stationary, the turbine fan rotates relative to the nozzle rod, and the turbine fan rotates together with the nozzle. Therefore, the relative rotation of the nozzle and the nozzle rod can achieve centrifugal slitting of the liquid mist, thereby greatly reducing the installation difficulty between the nozzle rod and the nozzle, significantly shortening the length of the rotating parts, extending the service life, and adding the centrifugal slitting function of the liquid mist, enabling the fog cannon nozzle to continuously and stably form a large-area spray, uniformly spraying pesticides, and achieving rapid pesticide control over a large area.

It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application. Unless otherwise specified, the methods used in this utility model are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Example 1

[0028] Depend on Figures 1-4 As shown, this utility model provides a fog cannon nozzle, which includes a nozzle housing 11, a nozzle 12, a nozzle rod 13, a turbine fan blade 14, and a support connecting rod 15. The nozzle housing 11 has a cylindrical structure, and the nozzle 12, nozzle rod 13, turbine fan blade 14, and support connecting rod 15 are housed inside it. The support connecting rod 15 is fixed inside the nozzle housing 11 and has an air inlet channel 111 and a first liquid inlet pipe 112. The nozzle rod 13 passes through the bottom of the nozzle 12 and the center hole of the turbine fan blade 14 from front to back and connects to the support connecting rod 15. The nozzle rod 13 has a second liquid inlet pipe 131, which is sealed and connected to the first liquid inlet pipe 112. The spray nozzle 1311 of the second liquid inlet pipe 131 faces the inner wall of the nozzle 12. The nozzle 12 has a hollow, cup-shaped structure with its opening facing forward. A gap 2 is provided between the nozzle 12 and the nozzle housing 11, and the gap 2 is connected to the air inlet channel 111. Wherein:

[0029] The bottom of the nozzle 12 is fixedly connected to the side wall of the turbine blade 14. The nozzle rod 13 passes through the bottom of the nozzle 12 and the center hole of the turbine blade 14 from front to back and is fixedly connected to the support connecting rod 15. The nozzle 12 and the nozzle rod 13 are spaced apart from each other, and the turbine blade 14 is rotatably connected to the nozzle rod 13.

[0030] The working process of this utility model: (from...) Figure 2 , Figure 4 As shown, during use, external pesticides enter the support connecting rod 15 through the first inlet pipe 112, and then through the second inlet pipe 131 inside the nozzle rod 13, and are sprayed from the spray nozzle 1311 towards and impact the inner wall of the nozzle 12. At the same time, external wind enters through the air inlet channel 111 between the support connecting rod 15 and the nozzle housing 11, blowing the turbine fan blade 14 and the nozzle 12 to rotate at high speed. The pesticides sprayed from the spray nozzle 1311 towards and impacting the inner wall of the nozzle 12 are centrifugally cut, torn and atomized by the nozzle 12, forming droplets and being thrown out. External wind blows out the sheared droplets through the gap 2 between the nozzle 12 and the nozzle housing 11 via the turbine fan blade 14, causing the droplets to be atomized again to form fine droplets. At the same time, the liquid mist is blown out and diffused in all directions to form a large area of ​​spray coverage, achieving large-area rapid spraying, which is suitable for pesticide spraying of crops, garden plant protection and other scenarios.

[0031] This utility model has a simple structure. In use, compared with the prior art, since the nozzle rod 13 is stationary and the turbine fan blade 14 rotates relative to the nozzle rod 13, and the turbine fan blade 14 rotates together with the nozzle 12, the relative rotation of the nozzle 12 and the nozzle rod 13 can realize the centrifugal cutting of liquid mist. This greatly reduces the installation difficulty between the nozzle rod 13 and the nozzle 12, significantly shortens the length of the rotating parts, extends the service life, and adds the centrifugal cutting function of liquid mist, so that the fog cannon nozzle 1 can continuously and stably form a large-area spray, and the pesticide is applied evenly, realizing the rapid and large-area pesticide killing.

[0032] As a preferred embodiment, by Figure 2 , Figure 4 As shown, the support connecting rod 15 is detachably and fixedly connected to the nozzle housing 11 by screws 3.

[0033] As a preferred embodiment, by Figure 2 , Figure 5 As shown, the nozzle rod 13 passes through the bottom of the nozzle 12 and the center hole of the turbine blade 14 from front to back, and is then detachably fixed to the support connecting rod 15 by threads, which facilitates installation and disassembly.

[0034] As a preferred embodiment, by Figure 2 , Figure 5As shown, the turbine blade 14 and the nozzle rod 13 are connected by a needle roller bearing 4, making the turbine blade 14 rotate more flexibly and stably.

[0035] As a preferred embodiment, by Figure 2 , Figure 5 As shown, the second liquid inlet pipe 131 has multiple spray nozzles 1311, which are evenly distributed along the circumferential direction of the head of the nozzle rod 13, making the spraying more uniform and the pesticide killing area larger.

[0036] As a preferred embodiment, by Figure 2 , Figure 3 As shown, gap 2 is an annular gap, which makes the spraying more uniform and the pesticide kills insects over a larger area.

Inside the sprayer housing 5, the fan 71 and the sprayer housing 5 with the air inlet hole 51 form an air inlet chamber 52, and the fan 71 and the sprayer housing 5 connected to the mist cannon nozzle 1 form an air outlet chamber 53.

Then, it is sprayed out from the exhaust port of the blower 71 at a high pressure and speed, and enters the mist cannon nozzle 1 through the air outlet chamber 53 and the air inlet channel 111, providing wind power for the operation of the mist cannon nozzle 1. On the other hand, the operator connects the liquid inlet interface 82 to the external spraying tank through the external pipeline.
