Description

Technical Field

[0001] This application relates to the field of pesticide spraying technology, and more particularly to a liquid atomizing nozzle and a pesticide application device including the same. Background Technology

[0002] Spraying pesticides on crops is a common practice in agricultural cultivation to protect them from pests and other harmful factors, ensuring their normal growth. Typically, agricultural spraying equipment mixes and pressurizes the pesticide solution with air within the device, then delivers the mixture through pipes to nozzles for atomization and spraying. However, these high-pressure atomizing nozzles are prone to clogging after prolonged operation or restarting after long periods of inactivity, as the pipe walls are constantly soaked in the gas-liquid mixture. In such cases, restoring the atomization effect requires increasing the gas-liquid mixture pressure, manually adjusting the nozzles, or replacing them. This limits the applicability of such spraying equipment, makes restoring operation time-consuming when multiple nozzles are clogged, and hinders automated operations. Utility Model Content

[0003] This application provides a liquid atomizing nozzle and a pesticide application device including the same, to solve the defect of easy clogging of atomizing nozzles in the prior art, and to realize a liquid atomizing nozzle with adjustable atomization effect and even a pesticide application device suitable for automated operation in agriculture.

[0004] According to a first aspect of this application, this application provides a liquid atomizing nozzle, including a plurality of infusion tubes, each infusion tube having its own liquid injection outlet; a gas infusion tube having a gas injection outlet; and movable connectors, the number of which is the same as the number of infusion tubes, each movable connector being configured to connect a corresponding infusion tube to the outer wall of the gas infusion tube, such that each liquid injection outlet is located at the distal end of the gas injection outlet, and the liquid ejected from each liquid injection outlet is located on the path of the pressurized gas jet stream ejected from the gas injection outlet.

[0005] According to the liquid atomizing nozzle provided in this application, a plurality of liquid delivery tubes are arranged at equal intervals on their outer walls relative to each other along the circumference of the gas delivery tube.

[0006] According to the liquid atomizing nozzle provided in this application, the number of infusion tubes is 4.

[0007] According to the present application, a liquid atomizing nozzle has a movable connecting member in the form of a telescopic rod.

[0008] According to the liquid atomizing nozzle provided in this application, the first end of each movable connector is hinged to the outer wall of the gas delivery pipe, and the second end of each movable connector is hinged to the corresponding liquid delivery pipe.

[0009] According to the liquid atomizing nozzle provided in this application, an annular limiting member is provided on the outer wall of the gas delivery pipe near the gas injection outlet. The annular limiting member has a number of slits, the number of which is consistent with the number of liquid delivery pipes, and each slit allows a corresponding liquid delivery pipe to pass through.

[0010] According to the liquid atomizing nozzle provided in this application, each slit extends radially along the gas delivery pipe, and the radial extension length of each slit is greater than the outer diameter of the liquid delivery pipe.

[0011] According to the liquid atomizing nozzle provided in this application, the width of each slit is slightly smaller than the outer diameter of the corresponding infusion tube, so that the slit and the corresponding infusion tube are interference-fitted.

[0012] According to the present application, a liquid atomizing nozzle comprises a plurality of movable connectors, each having an angle relative to the length direction of the gas delivery pipe and / or its respective extension or retraction, which may be the same or different relative to each other.

[0013] According to a second aspect of this application, this application also provides a drug application device, including at least one liquid atomizing nozzle as described in the first aspect of this application.

[0014] The liquid atomizing nozzle and the application device including it provided in this application separate the gas delivery route (i.e., the gas delivery pipe) from the liquid delivery route (i.e., one or more liquid delivery pipes), and eliminate the need to mix pressurized gas and liquid medicine within the application device. Therefore, compared to similar prior art devices, the gas delivery pipe and liquid delivery pipe are less prone to clogging by deposits, regardless of whether the application device is in operation or idle for extended periods. This makes the application device more suitable for automated operation scenarios. Furthermore, the liquid atomizing nozzle provided in this application adjusts the angle between the movable connector and the length direction of the gas delivery pipe, and / or its own extension / retraction, thereby adjusting the extension and inclination of the corresponding liquid delivery pipe, particularly its liquid spray outlet, relative to the gas delivery pipe, particularly its gas spray outlet, to achieve the desired atomization effect.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0026] The following is combined Figures 1 to 3 This application describes a liquid atomizing nozzle and a drug delivery device including the same.

[0027] Figure 1 This is a perspective view of the liquid atomizing nozzle provided in this application, such as... Figure 1 As shown, the liquid atomizing nozzle 100 includes one or more infusion tubes 110, gas infusion tubes 120, and one or more movable connectors 130, wherein the number of movable connectors 130 corresponds to the number of infusion tubes 110. In this embodiment, there are four infusion tubes 110, which means that there are also four movable connectors 130. Of course, in other embodiments, other configurations of the number of infusion tubes 110 and movable connectors 130 are also feasible. Preferably, as... Figure 3 The image shows a front view of the liquid atomizing nozzle provided in this application, with a plurality of infusion tubes 110 arranged at equal intervals on the outer wall of the gas infusion tube 120 relative to each other along the circumference of the gas infusion tube 120. As the name suggests, when there are four infusion tubes 110, any two adjacent infusion tubes 110 are angularly separated by 90° from each other on the circumference of the outer wall of the gas infusion tube 120; similarly, when there are three infusion tubes 110, any two adjacent infusion tubes 110 are angularly separated by 120° from each other on the circumference of the outer wall of the gas infusion tube 120, and so on.

[0028] like Figure 2 The diagram shows a side view of the liquid atomizing nozzle provided in this application. Each infusion tube 110 has its own liquid injection outlet 111. The gas infusion tube 120 has a gas injection outlet 121. Each movable connector 130 is configured to connect the corresponding infusion tube 110 to the outer wall of the gas infusion tube 120, such that each liquid injection outlet 111 is located at the distal end of the gas injection outlet 121, and the liquid medicine ejected from each liquid injection outlet 111 is exactly on the path of the pressurized gas jet stream ejected from the gas injection outlet 121. With the above configuration, during the operation of the liquid atomizing nozzle 100, the gas injection outlet 121 ejects a pressurized gas jet stream to its distal end. Simultaneously, each liquid injection outlet 111 is located at the distal end of the gas injection outlet 121. After being pressurized by an external pressurizing device, the liquid medicine is ejected from the liquid injection outlet 111 and mixed into the pressurized gas jet stream, thereby achieving gas-liquid mixing and even liquid atomization.

[0029] In particular, each movable connector 130 is configured to movably connect the corresponding infusion tube 110 to the outer wall of the gas infusion tube 120. Preferably, the movable connector 130 may be in the form of a telescopic rod. The first end 131 of each movable connector 130 is hinged to the outer wall of the gas infusion tube 120, while its second end 132 is hinged to the corresponding infusion tube 110, such that the movable connector 130 can pivot relative to both the gas infusion tube 120 and the infusion tube 110. Thus, by adjusting the amount of extension or retraction of the movable connector 130, the distance position of the liquid injection outlet 111 in front of the distal end of the gas injection outlet 121 can be changed; on the other hand, by adjusting the angle between the movable connector 130 and the longitudinal direction of the gas infusion tube 120, the angle of the liquid injection outlet 111 relative to the pressurized gas jet can be changed. By combining the changes in distance and angle, the incident position and angle of the liquid drug after it is ejected from the liquid injection outlet 111 and then injected into / mixed with the pressurized gas jet can be adjusted, thereby adjusting / changing the atomization effect of the mixture of liquid drug and pressurized gas.

[0030] Furthermore, an annular limiting member 122 is provided on the outer wall of the gas delivery pipe 120 near the gas injection outlet 121. The annular limiting member 122 has a plurality of slits 123. Similarly, the number of slits 123 corresponds to the number of infusion tubes 110, so that each slit 123 allows a corresponding infusion tube 110 to pass through. Here, the annular limiting member 122 with slits 123 restricts the movable dimension of each infusion tube 110, thereby keeping each infusion tube 110 in a coplanar plane with the virtual longitudinal axis of the gas delivery pipe 120. Each slit 123 extends radially along the gas delivery pipe 120, and the radial extension length of each slit 123 is greater than the outer diameter of the infusion tube 110, thereby allowing the infusion tube 110 to be adjusted to any position within the slit 123. This means that the infusion tube 110 passing through the slit 123 can be located either near the gas infusion tube 120 within the slit 123 or far away from the gas infusion tube 120. The advantage of this configuration is that even after adjusting the extension and angle of the movable connector 130, while keeping the extension and angle of the movable connector 130 constant, the distance, position, and angle of the liquid jet outlet 111 can still be changed by further adjusting the angle of each infusion tube 110 relative to the virtual longitudinal axis of the gas infusion tube 120. Figure 3 Taking the infusion tube 110 located at the top as an example, when the infusion tube 110 is at the top of the corresponding slit 123, the angle between the infusion tube 110 / liquid jet outlet 111 and the gas delivery tube 120 / virtual longitudinal axis is relatively small, and the liquid jet outlet 111 and the gas jet outlet 121 are far apart. However, when the infusion tube 110 is at the bottom of the corresponding slit 123, the angle between the infusion tube 110 / liquid jet outlet 111 and the gas delivery tube 120 / virtual longitudinal axis is relatively large, and the liquid jet outlet 111 and the gas jet outlet 121 are close together. In this way, by simply adjusting the spatial position of the infusion tube 110, the incident position and incident angle of the liquid medicine after being sprayed from the liquid jet outlet 111 and mixed into the pressurized gas jet can be adjusted, thereby adjusting / changing the atomization effect of the mixture of liquid medicine and pressurized gas.

[0031] On the other hand, to ensure that the adjusted infusion tubing 110 does not accidentally wobble, it is necessary to provide a means of securing the infusion tubing 110. For this purpose, the slit 123 can be designed such that its width extending circumferentially along the gas infusion tube 120 is slightly smaller than the outer diameter of the corresponding infusion tubing 110 passing through the slit 123. This achieves an interference fit between the slit 123 and the infusion tubing 110 passing through it; in other words, the slit 123 can clamp the infusion tubing 110 passing through it, preventing it from shifting. Additionally, the hinged connections of the first end 131 and the second end 132 of the movable connector 130 can be configured to be tight hinges, allowing these two hinged connections to remain in the desired pivot position without sufficiently large external intervention.

[0032] By combining the aforementioned adjustments to the movable connector 130 and the infusion tube 110, the incident position and angle of the liquid medicine onto the pressurized gas jet can be adjusted. It is conceivable that the angle between each movable connector 130 and the virtual longitudinal axis of the gas infusion tube 120, and / or their respective extension or retraction, may be the same or different relative to each other. Similarly, while keeping the extension or retraction and angle of the movable connector 130 constant, the angle between each infusion tube 110 and the virtual longitudinal axis of the gas infusion tube 120 can also be the same or different relative to each other. This means that the incident position and angle of the liquid medicine ejected from each liquid injection outlet 111 onto the pressurized gas jet can be the same or different relative to each other; that is, the atomization effect of the liquid medicine ejected from each infusion tube 110 can be the same or different relative to each other.

[0033] According to a second aspect of this application, this application also provides a drug application device, including at least one liquid atomizing nozzle 100 as described above.

[0034] When operating the application equipment of this application, the user can adjust the extension and angle of each movable connector 130, and / or adjust the spatial position of each infusion tube 110 to achieve the respective atomization effect of the liquid medicine sprayed from each infusion tube 110. The infusion tube 110 always delivers only the pre-prepared liquid medicine, without any other formulation components or impurities being delivered through it; similarly, the gas delivery tube 120 always delivers only pressurized gas. In this way, the infusion tube 110 and the gas delivery tube 120 each deliver only a single substance, reducing the risk of the pipes being blocked by condensate. Therefore, regardless of whether the application equipment of this application has undergone long-term operation or idleness, the infusion tube 110 and the gas delivery tube 120 can always remain unobstructed, making the application equipment of this application suitable for automated operation without frequent manual intervention and maintenance.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
