Description

Technical Field

[0001] This utility model relates to the field of agricultural drone technology, specifically to an agricultural drone nozzle. Background Technology

[0002] Agricultural drones are unmanned aerial vehicles used for agricultural and forestry plant protection operations. They achieve spraying operations through ground remote control or navigation flight control, and nozzles are required when spraying pesticides. CN220315295U discloses an agricultural drone nozzle, including a cylinder, a connecting pipe on one side of the cylinder, a solenoid valve on one side of the connecting pipe, a support column on the top of the cylinder, a connecting plate on the top of the support column, mounting holes on the surface of the connecting plate, a pressure relief valve on one side of the cylinder, a protective cover at the bottom of the cylinder, a fixing rod inside the protective cover, a motor on the top of the fixing rod, and an output shaft on the top of the motor. A filter plate can initially filter impurities in the pesticide solution, and a filter element can further filter fine impurities and sediments in the pesticide solution, preventing nozzle clogging during later use.

[0003] The existing nozzles have the following problems: Although filter plates and filter elements are used to filter out fine impurities and sediments in the liquid, after long-term use, some impurities still cannot be filtered out and accumulate at the nozzle, or other impurities in the air accumulate at the nozzle, causing the nozzle to become clogged and thus affecting the spraying effect.

[0004] Based on the above situation, there is an urgent need for a plant protection drone nozzle to solve the problem of nozzle clogging affecting the spraying effect. Utility Model Content

[0005] The purpose of this invention is to address the problem that, although existing spray nozzles use filter plates and filter elements to filter out fine impurities and sediments in the liquid, some impurities still cannot be filtered out after long-term use and accumulate at the nozzle, or other impurities in the air accumulate at the nozzle, causing the nozzle to become clogged and thus affecting the spraying effect. This invention solves the problem of nozzle clogging affecting the spraying effect.

[0006] The technical solution of this utility model is as follows: A plant protection drone nozzle includes: A cylindrical body, on which a nozzle is mounted; The infusion tube is connected to the cylinder body; A check valve is installed on the infusion tubing; A self-cleaning mechanism is installed on the cylinder. The self-cleaning mechanism includes a cleaning needle for unclogging the nozzle, and the cleaning needle is connected to a telescopic rod.

[0007] Existing spray nozzles, although using filter plates and filter cartridges to filter out fine impurities and sediments in the liquid, still retain some impurities after long-term use, which accumulate at the nozzle. Other impurities in the air also accumulate at the nozzle, causing clogging and affecting the spraying effect. In this solution, after the spray nozzle has been used several times, the check valve is closed, and the telescopic rod drives the cleaning needle to approach and pierce the nozzle, thereby cleaning the blockage accumulated in the nozzle and restoring the spraying effect. This solves the problem of spray nozzle clogging affecting the spraying effect.

[0008] Furthermore, to facilitate the disassembly of the self-cleaning mechanism, one feasible solution is to detachably install a cover on the cylinder, with the self-cleaning mechanism connected to the cover. In this solution, the self-cleaning mechanism can be maintained by disassembling the cover.

[0009] Furthermore, to ensure the airtightness of the cover, one feasible solution is that the cover is threadedly connected to the cylinder and a sealing gasket is installed between the cover and the cylinder. When this solution is adopted, the sealing gasket seals the cover and the cylinder to prevent the medicine from leaking out.

[0010] Furthermore, to facilitate the replacement of the cleaning needle, one feasible solution is that the cleaning needle is connected to a mounting base, and the mounting base is threadedly connected to the telescopic rod. With this solution, the cleaning needle can be easily and quickly disassembled by turning the mounting base, so as to facilitate the replacement of the cleaning needle.

[0011] Furthermore, in order to protect the cleaning needle, one feasible solution is to form a sleeve for protecting the cleaning needle inside the cylinder, and a bracket is provided between the sleeve and the cylinder. When this solution is adopted, the cleaning needle is limited by the sleeve, which can prevent the cleaning needle from bending and thus protect the cleaning needle.

[0012] Furthermore, to facilitate the entry of the cleaning needle into the sleeve, one feasible solution is to form an enlarged section at one end of the sleeve near the telescopic rod. When this solution is adopted, the guiding effect of the enlarged section facilitates the entry of the cleaning needle into the sleeve.

[0013] Furthermore, to automate the cleaning of the nozzles, one feasible solution is to install a pressure sensor on the cylinder body. The pressure sensor is used to control the check valve and the telescopic rod. In this solution, the pressure sensor detects the internal pressure of the cylinder body. When the pressure value is greater than a preset value, the check valve is controlled to close, and then the telescopic rod is controlled to drive the cleaning needle to pierce the nozzle for cleaning. After cleaning is completed, the check valve and the telescopic rod are controlled to reset so that the spraying operation can continue.

[0014] Compared with existing technologies, the beneficial effects of this utility model are: 1. After the nozzle has been used several times, the check valve is closed, and the telescopic rod drives the cleaning needle to approach and pierce the nozzle, thereby cleaning the blockage accumulated in the nozzle and restoring the spraying effect. This solves the problem of nozzle blockage affecting the spraying effect. Second, since a sleeve for protecting the cleaning needle is formed inside the cylinder, and a bracket is provided between the sleeve and the cylinder, the cleaning needle is limited by the sleeve, which can prevent the cleaning needle from bending and thus protect the cleaning needle. Third, since a pressure sensor is installed on the cylinder, the pressure sensor is used to control the check valve and the telescopic rod. The pressure sensor detects the internal pressure of the cylinder. When the pressure value is greater than the preset value, the check valve is controlled to close, and then the telescopic rod is controlled to drive the cleaning needle to pierce the nozzle for cleaning. After cleaning is completed, the check valve and the telescopic rod are controlled to reset so that the spraying operation can continue. Attached Figure Description

[0017] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0018] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0019] Example: Please refer to Figure 1 , Figure 2 and Figure 3 A plant protection drone nozzle includes: Cylinder 1, on which nozzle 11 is installed; Infusion tube 2 is connected to cylinder 1; Check valve 3 is installed on infusion tubing 2; The self-cleaning mechanism 4 is installed on the cylinder 1. The self-cleaning mechanism 4 includes a cleaning needle 41 for unclogging the nozzle 11. The cleaning needle 41 is connected to a telescopic rod 42.

[0020] Existing spray nozzles, although using filter plates and filter cartridges to filter out fine impurities and sediments in the liquid, still have some impurities that cannot be filtered out after long-term use and accumulate at the nozzle, or other impurities in the air accumulate at the nozzle, causing nozzle blockage and affecting the spraying effect. In this solution, after the spray nozzle has been used several times, the check valve 3 is closed, and the telescopic rod 42 drives the cleaning needle 41 to approach and pierce the nozzle 11, thereby cleaning the blockage accumulated in the nozzle 11 and restoring the spraying effect, thus solving the problem of nozzle blockage affecting the spraying effect.

[0021] To facilitate the disassembly of the self-cleaning mechanism 4, one feasible solution is to detachably install a cover 12 on the cylinder 1, and connect the self-cleaning mechanism 4 to the cover 12. When this solution is adopted, the self-cleaning mechanism 4 can be maintained by disassembling the cover 12.

[0022] To ensure the airtightness of the cover 12, one feasible solution is to thread the cover 12 to the cylinder 1 and install a sealing gasket 13 between the cover 12 and the cylinder 1. When this solution is adopted, the sealing gasket 13 seals the cover 12 and the cylinder 1 to prevent the medicine from leaking out.

[0023] Reference Figure 3 and Figure 5 To facilitate the replacement of the cleaning needle 41, one feasible solution is that the cleaning needle 41 is connected to a mounting base 43 and the mounting base 43 is threadedly connected to the telescopic rod 42. When this solution is adopted, the cleaning needle 41 can be easily and quickly disassembled by turning the mounting base 43, so as to facilitate the replacement of the cleaning needle 41.

[0024] Reference Figure 4 and Figure 6 In order to protect the cleaning needle 41, one feasible solution is to form a sleeve 14 inside the cylinder 1 to protect the cleaning needle 41, and a bracket 15 is provided between the sleeve 14 and the cylinder 1. When this solution is adopted, the cleaning needle 41 is limited by the sleeve 14, which can prevent the cleaning needle 41 from bending and thus protect the cleaning needle 41.

[0025] To facilitate the entry of the cleaning needle 41 into the sleeve 14, one feasible solution is to form an enlarged section 141 at one end of the sleeve 14 near the telescopic rod 42. When this solution is adopted, the guiding effect of the enlarged section 141 facilitates the entry of the cleaning needle 41 into the sleeve 14.

[0026] Reference Figure 1 To automate the cleaning of the nozzles, one feasible solution is to install a pressure sensor 5 on the cylinder 1. The pressure sensor 5 is used to control the check valve 3 and the telescopic rod 42. When this solution is adopted, the pressure sensor 5 detects the internal pressure of the cylinder 1. When the pressure value is greater than the preset value, the check valve 3 is controlled to close, and then the telescopic rod 42 is controlled to drive the cleaning needle 41 to pierce the nozzle 11 for cleaning. After cleaning is completed, the check valve 3 and the telescopic rod 42 are controlled to reset so that the spraying operation can continue.

[0027] To address the issue of nozzle clogging affecting spraying performance, this solution involves closing the check valve 3 after several uses of the nozzle. The telescopic rod 42 then drives the cleaning needle 41 to approach and pierce the nozzle 11, thereby cleaning the accumulated blockage inside the nozzle 11 and restoring the spraying effect. This solves the problem of nozzle clogging affecting spraying performance.

[0028] In order to protect the cleaning needle 41, in this solution, a sleeve 14 for protecting the cleaning needle 41 is formed inside the cylinder 1, and a bracket 15 is provided between the sleeve 14 and the cylinder 1. The sleeve 14 limits the cleaning needle 41, which can prevent the cleaning needle 41 from bending, thereby protecting the cleaning needle 41.

[0029] To automate the cleaning of nozzle 11, in this solution, a pressure sensor 5 is installed on the cylinder 1. The pressure sensor 5 is used to control the check valve 3 and the telescopic rod 42. The pressure sensor 5 detects the internal pressure of the cylinder 1. When the pressure value is greater than the preset value, the check valve 3 is closed, and the telescopic rod 42 is then controlled to drive the cleaning needle 41 to pierce the nozzle 11 for cleaning. After cleaning is completed, the check valve 3 and the telescopic rod 42 are reset so that the spraying operation can continue.
