Description

Technical Field

[0001] This utility model relates to the field of drones, and in particular to a drone spraying boom. Background Technology

[0002] Drones have a wide range of applications. In the agricultural field, drones are equipped with spray booms. After the drone flies over the farmland, it sprays pesticides into the farmland through the nozzles on the spray booms to complete the pesticide spraying work.

[0003] Most existing drone spraying booms only have a single pesticide spraying liquid path. After each pesticide spraying, it is not convenient for staff to quickly clean the pipes, which may cause pesticide residue to corrode or clog the pipes or nozzles. In addition, the pipes of existing spraying booms are mostly located on the outside. The wind resistance generated by the drone during flight can easily cause the pipes to loosen, fall off, or crack and be damaged, making them inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to solve the following problems existing in the prior art: Most existing drone spraying booms only have a single pesticide spraying liquid path. After each pesticide spraying is completed, it is not convenient for staff to quickly clean the pipes, which may cause pesticide residue to corrode or block the pipes or nozzles. In addition, the pipes of existing spraying booms are mostly set on the outside. With the wind resistance generated during the flight of the drone, the pipes are prone to loosening, falling off or cracking and being damaged, which is inconvenient to use.

[0005] To address the problems existing in the prior art, this utility model provides a drone spraying boom, including a connecting rod and a side rod. The connecting rod has an internal adapter valve, and the input end of the adapter valve is respectively provided with a main cleaning pipe and a main drug delivery pipe. Both sides of the side rod are provided with nozzles, and the output end of the adapter valve is connected to the nozzles with a secondary cleaning pipe and a secondary drug delivery pipe, respectively.

[0006] Furthermore, each of the side rods has a groove at its inner top, and the groove is divided into two pipe channels by a partition.

[0007] Furthermore, the auxiliary cleaning tube and the auxiliary drug delivery tube respectively pass through the grooved pipe channel, and the top of the groove is provided with a protective cover.

[0008] Furthermore, the nozzle is equipped with a flow sensor, which is electrically connected to the control system of the UAV.

[0009] Furthermore, a connecting seat is provided at the top of the connecting rod, through which the drone is connected to the connecting rod.

[0010] Furthermore, the spray bar is formed as a whole by connecting rods and side rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model's liquid circuit system adopts a dual-pipeline design. After the operation is completed, cleaning water is delivered to the auxiliary cleaning pipe and the auxiliary drug delivery pipe through the main cleaning pipe. First, the auxiliary drug delivery pipe is flushed with cleaning water and discharged through the nozzle. Then, the cleaning water in the auxiliary cleaning pipe is delivered to the nozzle for further cleaning. This allows for quick switching to the cleaning mode after the operation is completed, preventing residual liquid from causing corrosion and blockage of the pipes or nozzles. The design of the side rod groove and protective cover not only facilitates the inspection and maintenance of the pipes by the staff, but also provides a limiting protection effect for the dual liquid circuit pipes, preventing the pipes from loosening, falling off, or cracking due to external wind force, thus increasing the practicality of this device.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation details without creative effort are all within the protection scope of this invention.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] Example 1

[0020] like Figure 1-3 As shown, a drone spraying boom includes a connecting rod 1 and a side rod 2. The connecting rod 1 is equipped with a transfer valve 3. The input end of the transfer valve 3 is equipped with a main cleaning pipe 7 and a main drug delivery pipe 8. Both sides of the side rod 2 are equipped with nozzles 5. The output end of the transfer valve 3 is connected to the nozzles 5 with a secondary cleaning pipe 11 and a secondary drug delivery pipe 12, respectively.

[0021] In this embodiment, the inner top of the side rod 2 is provided with a groove 10. The groove 10 is divided into two pipeline channels by a partition. The pipelines of the auxiliary cleaning pipe 11 and the auxiliary drug delivery pipe 12 pass through the pipeline channels of the groove 10 respectively. The top of the groove 10 is provided with a protective cover 4. The nozzle 5 is provided with a flow sensor 6. The flow sensor 6 is electrically connected to the control system of the drone. The top of the connecting rod 1 is provided with a connecting seat 9. The drone and the connecting rod 1 are connected through the connecting seat 9. The connecting rod 1 and the side rod 2 form an integral spraying rod.

[0022] Working Principle Description: The operator connects the connecting rod 1 to the drone via the connecting seat 9, and then connects the main cleaning pipe 7 and the main pesticide delivery pipe 8 to the cleaning tank and pesticide tank respectively to complete the connection and deployment. During use, the main pesticide delivery pipe 8 delivers pesticides through the auxiliary pesticide delivery pipe 12 to the nozzle 5 for spraying, thus completing the pesticide spraying work. After the operation is completed, the main cleaning pipe 7 delivers cleaning water to both the auxiliary cleaning pipe 11 and the auxiliary pesticide delivery pipe 12. First, the auxiliary pesticide delivery pipe 12 is flushed with the cleaning water and discharged through the nozzle 5. Subsequently, the cleaning water in the auxiliary cleaning pipe 11 is delivered to the nozzle 5 for further cleaning, thus completing the rapid cleaning process. The liquid circuit system of this device adopts... The dual-pipe design features one pipe for delivering pesticide or fertilizer solutions and the other for delivering cleaning fluid. This allows for quick switching to cleaning mode after operation to clean the nozzles 5 and pipes, preventing residual liquid from corroding or clogging the equipment. The design of the inner groove 10 of the side rod 2 and the protective cover not only facilitates maintenance and repair of the pipelines but also provides limiting protection for the dual-liquid pipelines, preventing them from loosening, falling off, or cracking due to external wind. The flow sensor 6 monitors the liquid flow rate of the nozzles 5 in real time. When the flow sensor 6 detects an abnormal flow rate, the drone system can promptly issue an alarm and adjust the valve opening of the corresponding nozzle 5 to ensure uniform spraying and increase the practicality of the device.
