DETAILED DESCRIPTION

[0015] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0016] As Figs. 1 to 4 Indicated, a kind of spraying equipment for unmanned aerial vehicles, applied to unmanned aerial vehicle body 100, including mounting plate 101, the mounting plate 101 is installed in unmanned aerial vehicle body 100 bottom, the bottom of the mounting plate 101 is fixed with fixed plate 102, the bottom of the fixed plate 102 is rotatably equipped with medicine storage barrel 103, the opening of the medicine storage barrel 103 is equipped with barrel cover 105, the barrel cover 105 is communicated with spray head 104, the bottom of the fixed plate 102 is equipped with swing mechanism 200 capable of making that medicine in medicine storage barrel 103 mixes more evenly.

[0017] In this embodiment, the swing mechanism 200 includes a rotating shaft 203 rotatably mounted on the bottom of a fixed plate 102. A motor 204 is mounted on the top of the fixed plate 102, and the output shaft of the motor 204 is connected to the top of the rotating shaft 203. Multiple supports 201 are mounted on the bottom of the rotating shaft 203, and a base plate 106 is rotatably mounted on the top. The medicine storage tank 103 is fixedly mounted on the base plate 106. A first bevel gear 202 is fixedly mounted on the bottom of the fixed plate 102. The first bevel gear 202 is coaxially mounted with the rotating shaft 203. A slot 205 is opened on the support 201, and a rotating rod 209 is rotatably mounted in the slot 205. A second bevel gear 208 that meshes with the first bevel gear 202 is fixedly sleeved on the body of the rotating rod 209. Synchronous pulleys 206 are fixedly sleeved on both the end of the rotating rod 209 and the end of the rotating shaft of the base plate 106. A synchronous belt 207 is provided between the synchronous pulleys 206.

[0018] When the motor 204 is started, its output shaft drives the rotating shaft 203 to rotate via a transmission connection. The bracket 201 at the bottom of the rotating shaft 203 rotates accordingly, which in turn drives the storage tank 103 to rotate and swing. As the bracket 201 rotates, it drives the second bevel gear 208 to mesh with the first bevel gear 202, thereby driving the rotating rod 209 to rotate. Through the transmission action of the synchronous belt 207 and the synchronous pulley 206, the base plate 106 and the storage tank 103 fixed on the base plate 106 rotate on their own axis. This allows the storage tank 103 to revolve around the rotating shaft 203 while also rotating on its own axis. This helps to keep the pesticide solution in the storage tank 103 evenly mixed during the drone's flight, preventing the pesticide solution from settling due to vibration and airflow. It ensures the consistency and efficiency of the spraying effect. Because the pesticide solution concentration is uniform, the pesticide solution sprayed on the crops can cover the leaves more evenly, reducing crop damage caused by uneven pesticide solution concentration.

[0019] In this embodiment, both the base plate 106 and the lid 105 are provided with reinforcing plates 107.

[0020] The reinforcing plates 107 installed on the base plate 106 and the lid 105 enhance the overall stability of the equipment, making the swing mechanism 200 more stable and reliable when it drives the medicine storage tank 103 to swing.

[0021] In this embodiment, a sealing strip 108 is provided on the side of the barrel lid 105 that contacts the medicine storage barrel 103.

[0022] The sealing strip 108 ensures a good seal between the lid 105 and the medicine storage tank 103 to prevent leakage of the medicine.

[0023] Working process and principle: when the device is used, the pesticide solution which has been diluted and stirred according to a specific ratio is loaded into the medicine storage barrel 103, the spray head 104 is connected with the barrel cover 105, which is used for uniformly spraying the liquid medicine during the flight of the unmanned aerial vehicle, when the unmanned aerial vehicle body 100 takes off, the motor 204 is started, the output shaft of the motor 204 drives the rotating shaft 203 to rotate through the transmission connection, the bracket 201 arranged at the bottom of the rotating shaft 203 rotates, and then drives the medicine storage barrel 103 to rotate and swing, when the bracket 201 rotates, the second bevel gear 208 and the first bevel gear 202 are meshed and connected, so that the rotating rod 209 is driven to rotate, through the transmission action of the synchronous belt 207 and the synchronous pulley 206, the bottom plate 106 and the medicine storage barrel 103 fixed on the bottom plate 106 are driven to rotate, the medicine storage barrel 103 is realized to revolve around the rotating shaft 203 while rotating, which is helpful to keep the liquid medicine in the medicine storage barrel 103 mixed uniformly during the flight of the unmanned aerial vehicle, prevent the liquid medicine from being precipitated due to vibration and air flow, and ensure the consistency and efficiency of the spraying effect, since the liquid medicine concentration is uniform, the liquid medicine sprayed on crops can be more uniformly covered on the leaves, and the problem of crop damage caused by uneven liquid medicine concentration is reduced.

[0024] From the technical common sense, the utility model can realize through other implementation schemes which do not deviate from the spiritual substance or essential characteristics. Therefore, the above disclosed implementation scheme is just an example, and is not the only one. All changes within the scope of the utility model or within the scope equivalent to the utility model are included in the utility model.
