发明内容
为解决现有技术存在的传统农业喷洒作业效率低，人工喷洒农药辛苦，作业效率易受到自然环境的影响，在炎热的环境下作业让喷药人好中暑，甚至会发生意外，本发明提供一种农业无人机喷洒装置。
为了解决上述技术问题，本发明提供了如下的技术方案：
本发明一种农业无人机喷洒装置，包括旋翼和发动机，所述旋翼与底部设有的发动机的输出轴传动连接，所述发动机的一侧设置有启动拉绳，所述发动机的底部通过软管连接设置有油箱，所述油箱的顶部一侧连通设置有注油口，所述注油口的表面螺纹连接有油盖，所述油箱的底部安装有飞行控制器，所述飞行控制器的两侧均对称焊接有两根机壁，四根所述机壁的顶部通过电动马达传动连接设置有正反螺旋桨，四根所述机壁的底部均与中心架焊接固定，所述中心架底端横杆的顶部安装有喷药箱，所述喷药箱通过螺杆与中心架固定连接，所述喷药箱的底部边侧通过软管与中心架底部固定安装的电动增压泵的抽液口连通，，所述电动增压泵底部的出液口密封连接设置有喷管，所述喷管的两端通过连接杆与中心架焊接的支腿固定连接，所述喷管的底部安装有若干个喷雾头。
进一步的，所述飞行控制器的底部固定安装有蓄电池。
进一步的，其中一根所述机壁的底部通过固定块安装有摄像机，所述摄像机与飞行控制器电性连接。
进一步的，其特征在于，所述飞行控制器的内部还设置有方向控制模块、摄像模块、GPS定位模块、电动增压泵控制模块和指令接收与控制模块，所述指令接收与控制模块的表面穿插设置有接收天线，所述发动机和电动马达与内部设有的方向控制模块电性连接，所述摄像机与摄像模块电性连接，所述电动增压泵通过与电动增压泵控制模块电性连接，所述GPS定 位模块和指令接收与控制模块电性连接，所述指令接收与控制模块通过接收天线发送的无线电信号与移动控制终端无线连接，所述飞行控制器与蓄电池电性连接。
与现有技术相比，本发明具有如下有益效果：该种农业无人机喷洒装置通过设有的旋翼、发动机、电动增压泵喷管和喷头，经过在地面控制平台往无人机发射指令信号，再通过无人机飞行控制器内部所设有指令接收与控制模块进行接收处理，从而将电磁波信号转化为电性号，继而开启电动增压泵模块进行吸气增压，产生足够的压力将药液从喷管底部所设有的喷雾头处喷出，此时的GPS定位模块以及方向控制模块接收地面客户端发出的指令来对无人机进行平稳的移动，以及实时的进行定位，通过将药液在空中对其进行喷洒极大的增加了除草杀虫的效率，使药液的在喷洒的覆盖率相比较人工更加的均匀，从而减轻了人工喷洒农药繁重的工作量，降低了人工喷药中毒的风险，通过机械操继而减轻作业人员受到炎热环境的影响，从而推动农业种植的快速的发展。

具体实施方式
为使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体实施方式，进一步阐述本发明。
如图1-2所示，一种农业无人机喷洒装置，包括旋翼1和发动机2，旋翼1与底部设有的发动机2的输出轴传动连接，发动机2的一侧设置有启动拉绳，发动机2的底部通过软管连接设置有油箱3，油箱3的顶部一侧连通设置有注油口4，注油口4的表面螺纹连接有油盖，油箱3的底部安装有飞行控制器17，飞行控制器17的两侧均对称焊接有两根机壁13，四根机壁13的顶部通过电动马达传动连接设置有正反螺旋桨5，四根机壁13的底部均与中心架15焊接固定，中心架15底端横杆的顶部安装有喷药箱7，喷药箱7通过螺杆与中心架15固定连接，喷药箱7的底部边侧通过软管与中心架15底部固定安装的电动增压泵8的抽液口连通，，电动增压泵8底部的出液口密封连接设置有喷管9，喷管9的两端通过连接杆12与中心架15焊接的支腿11固定连接，喷管9的底部安装有若干个喷雾头10。
其中，飞行控制器17的底部固定安装有蓄电池14，蓄电池14为无人机的用电设备提供电能。
其中，其中一根机壁13的底部通过固定块6安装有摄像机16，摄像机16与飞行控制器17电性连接，方便使用人员对无人机进行操控，以便于躲避飞行过程当中的障碍物。
其中，飞行控制器17的内部还设置有方向控制模块、摄像模块、GPS定位模块、电动增压泵控制模块和指令接收与控制模块，指令接收与控制模块的表面穿插设置有接收天线，发动机2和电动马达与内部设有的方向控制模块电性连接，摄像机16与摄像模块电性连接，电动增压泵8通过与电动增压泵控制模块电性连接，GPS定位模块和指令接收与控制模块电性连接，指令接收与控制模块通过接收天线发送的无线电信号与移动控制终端无线连接，飞行控制器17与蓄电池14电性连接。操作人员方便在地面对农业喷洒无人机进行控制，发出一些复杂的指令从而代替人工在炎热的天气里进行作业，代替人工完成对农作物的喷洒任务。
需要说明的是，本发明为一种农业无人机喷洒装置，具体使用时，使用人员可先将喷药箱7底部与中心架15固定的螺栓和螺丝卸下，拧开喷药箱盖，将需要喷洒的药液或者药粉和水从注药口处倒入，之后拧紧盖子重新将喷药箱7通过螺栓再与中心架15进行固定，将喷药箱7一侧设有的软管与电动增压泵7的抽液口连接，检查好油箱3内的油量以及仪器设备，之后拉起发动机2一侧设有的拉绳启动发动机2，发动机2启动后随着发动机2的转动下，来带动顶部的旋翼1进行旋转，这时使用人员可通过操作平板电脑来对无人机发送发动机2上升指令，飞行控制器17内部的指令接收与控制模块接收到指令后协调给油，通过增加发动机2的转速让其能够足够大的动力进行上升，这时四根机壁13顶部设有的四个电动马达同时启动带动着顶部的正反螺旋桨5产生飞升的作用力，此时从地面控制端向无人机发送GPS定位和摄像指令，经过指令接收模与控制模块的处理后将电磁信号转化成电信号，对摄像头进行开启，这时平板电脑反馈到摄像机16拍摄的实时画面，之后再对电动增压泵8进行开启，将喷药箱7里的药液抽取到电动增压泵8内进行加压然后注入至电动增压泵8底部连通的喷管9内，然后从喷管9底部设有的若干个喷雾头10内喷射出，从而代替人工来对农作物实行喷洒药物的工作，操作人员在地面上边观察边调整喷洒的高度与距离，结合GPS定位和摄像通过在屏幕上进行观察，从而保证喷洒过程中的均匀性，通过飞行控制器17内部所设有的方向控制模块与摄像机所传来的图像来对其进行方向性的移动从而增加喷药的覆盖范围，使药液在空中落下时能够最大限度的与杂草飞虫接触，从而达到彻底杀灭害虫杂草的效果。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
