具体实施方式
为了更好理解本发明技术内容，下面提供具体实施例，并结合附图对本发明做进一步的说明。
参见图1～4，一种橡胶林无人机喷粉效果测试装置，包括导气管1、挡板2、吸附板3、扭力弹簧4、电机5、限位块6、限位杆7和第一伸缩杆8，所述导气管1中部设有第一开口9，所述第一开口9下方沿着气流方向依次转动连接所述 挡板2和吸附板3，所述挡板2和吸附板3上部均设有与所述导气管1内径相同的通气孔10，所述挡板2下部设有通过粉末的夹缝11，所述挡板2和吸附板3分别与所述扭力弹簧4连接，两个所述扭力弹簧4分别与蜗轮12连接，所述扭力弹簧4驱动所述挡板2与吸附板3绕着相反方向转动，所述蜗轮12与固定在所述电机5上的蜗杆13啮合，所述挡板2和吸附板3顶部分别设有所述限位块6，所述导气管1顶部设有所述第一伸缩杆8和限位杆7，所述限位杆7底部设有用于通过限位块6的通槽14，所述第一伸缩杆8用于驱动所述限位杆7往复移动，所述通槽14与限位块6错位时限位杆7限制所述挡板2和吸附板3转动，所述通槽14与限位块6对齐时所述挡板2和吸附板3转动的限制解除。
本发明安装在无人机喷粉机的粉末喷出口位置，无人机喷粉机喷出的粉末进入导气管1，并沿着导气管1流动。在导气管1的中部设有第一开口9，第一开口9下方沿着气流方向依次转动连接所述挡板2和吸附板3，挡板2和吸附板3转动时可以从第一开口9进出导气管1，挡板2和吸附板3上部均设有与所述导气管1内径相同的通气孔10，在没有进行喷粉测试时通气孔10与导气管1重合，粉末混合气沿着导气管1穿过通气孔10喷出。挡板2和吸附板3分别与所述扭力弹簧4连接，两个所述扭力弹簧4分别与蜗轮12连接，在进行检测之前，驱动电机5转动，电机5通过涡轮蜗杆13传动驱动扭力弹簧4转动蓄力，使得扭力弹簧4存储弹性势能，蜗轮蜗杆具有自锁效果，避免扭力弹簧4反向驱动电机5转动。由于挡板2和吸附板3顶部分别设有限位块6，导气管1顶部设有所述第一伸缩杆8和限位杆7，第一伸缩杆8伸缩时候带动限位杆7移动，限位杆7底部设有用于通过限位块6的通槽14，当通槽14与限位块6错位时，限位杆7挡住了限位块6的移动，从而限制所述挡板2和吸附板3转动，因此在电机5驱动扭力弹簧4蓄力时挡板2与吸附板3固定不动。在检测时，第一伸缩 杆8驱动限位杆7移动，使得通槽14与限位块6对齐后，接着继续移动使通槽14与限位块6错位，限位块6失去限位作用后移动使得挡板2与吸附板3可以转动，在挡板2和吸附板3旋转一周后回到初始位置时被限位杆7挡住，恢复至初始状态。在挡板2与吸附板3转动的过程中，扭力弹簧4驱动挡板2和吸附板3绕着相反方向转动，挡板2与吸附板3扫过导气管1的气流通道，挡板2下部设有通过粉末的夹缝11，夹缝11扫过导气管1，无人机喷粉机喷出的粉末穿过夹缝11打在吸附板3上。吸附板3与挡板2的转动方向相反，在夹缝11的作用下缩小了粉末穿过的横截面，使得吸附板3暴露的时间很短，使得粉末打在吸附板3上被吸附，观察吸附板3的粉末吸附情况可以判断出无人机喷粉机的喷粉喷出时的混合情况。扭力弹簧4驱动挡板2和吸附板3转动，扭力弹簧4在释放势能时形变的惯性小，在转动时便于挡板2和吸附板3获得较大的转动速度。
具体的，所述吸附板3设有可拆卸的吸附纸15，所述吸附纸15具有粘性。可选的，吸附纸15双面具有粘性，一面粘附在吸附板3上，另一面用于粘附粉末。
可选的，所述夹缝11靠近所述挡板2中心一端的宽度小于远离挡板2中心一端的宽度。靠近挡板2中心的一端转动速度慢，远离挡板2中心的一端转动速度快，夹缝11靠近所述挡板2中心一端的宽度小于远离挡板2中心一端的宽度，使得粉末吸附在吸附板3上更加均匀。
具体的，所述挡板2和吸附板3分别转轴16连接，所述导气管1设有安装座17，所述转轴16与所述安装座17转动连接，所述扭力弹簧4一端与第一转轴16连接，另一端与所述蜗轮12连接。挡板2和吸附板3分别和转轴16固定连接，扭力弹簧4驱动与挡板2连接的转轴16转动时带动挡板2转动，另一个 扭力弹簧4驱动与吸附板3连接的转轴16转动时带动吸附板3转动。两个扭力弹簧4各与蜗轮12连接，蜗轮12转动时将扭力弹簧4拧紧。
具体的，所述蜗杆13设有弹簧套筒18，所述扭力弹簧4设于所述弹簧套筒18内，且一端与所述弹簧套筒18固定连接。扭力弹簧4设于套筒内起到保护的作用。
具体的，所述导气管1包括导风套19和栅格套筒20，所述导风套19筒和栅格套筒20的顶部通过连接件相互连接，可选的，连接件可为防护盒24，所述第一开口9设于所述导风套19与所述栅格套之间，所述所述栅格套筒20侧面设有若干进出气孔21。当挡板2和吸附板3转动将导气管1的气流通道挡住时，粉末气体混合物从栅格套筒20侧面的进出气孔21排出，减少粉末气体混合物滞留。在进出气孔21开始时外界气压高于导气管1内气压时，还可以进入导气管1内。
具体的，所述栅格套筒20滑动连接有挡风罩22，所述挡风罩22与第二伸缩杆23连接，所述第二伸缩杆23固定在所述栅格套筒20上。挡风罩22与栅格套筒20滑动连接，第二伸缩杆23驱动挡风罩22滑动将栅格套筒20的进出气孔21挡住，在没有进行检测时进出气孔21不通。在进行检测时第二伸缩杆23驱动挡风罩22将进出气孔21开启，使得粉末气体混合物可以从进出气孔21排出。
具体的，所述导气管1设有防护盒24，所述吸附板3、扭力弹簧4、电机5、限位块6、限位杆7和第一伸缩杆8均设于所述防护盒24内。防护盒24避免从栅格套筒20的进出气孔21出来的粉末进入吸附板3、扭力弹簧4、电机5、限位块6、限位杆7和第一伸缩杆8内。
具体的，所述防护盒24底部设有第二开口25，所述第二开口25设有盖子26。开启第二开口25可以进行更换吸附纸15，操作方便。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
