实施例一
如图1-图3所示，本发明实施例提供一种药箱盖，可用于植保无人机的药箱上。该药箱盖包括箱盖本体10和进药组件20，其中箱盖本体10与药箱的进药口连接，箱盖本体10上设有第一开口11；进药组件20设于箱盖本体10的第一开口11处，进药组件20包括外套筒21和内套筒22；外套筒21顶端设有第一法兰213，并通过第一法兰213固定于箱盖本体10上；外套筒21上端敞口，整体形状可为圆筒形；外套筒21的侧壁间隔均匀开设有多个第一进药口211，优选的，该第一进药口211沿外套筒21的轴向延伸，可以从侧壁的顶部延伸至底部；具体而言，可以将第一进药口211设为矩形。为提高进药效率，外套筒21的底壁也可以间隔均匀开设有多个第一进药口211，优选的，底壁的多个第一进药口211沿中心呈辐射状均匀分布，第一进药口211的形状为扇形。
内套筒22设置于外套筒21的圆柱形内腔之中，且与外套筒21小间隙配合，即两者能够实现相对自由转动而又保持密封性；内套筒22上端敞口，其侧壁间隔均匀开设有多 个第二进药口221，优选的，该第二进药口221沿外套筒22的轴向延伸，可以从侧壁的顶部延伸至底部；具体而言，可以将第二进药口221设为矩形；同外套筒21一样，内套筒22的底壁也可以间隔均匀开设有多个第二进药口221，优选的，底壁的多个第二进药口221沿中心呈辐射状均匀分布，第二进药口221的形状为扇形。内套筒22在外套筒21内转动的过程中，第一进药口211与第二进药口221相配合开闭，进药口的均匀分布能使内、外套筒的进药口连通时，进药口面积最大化，进药效率更高。进药组件20可以在图4所示全开状态和图5所示全关状态之间连续改变状态：当侧壁的第一进药口211与第二进药口221配合打开时，底壁的第一进药口211与第二进药口221同时配合打开，此时，可以通过内套筒22的敞口向内套筒22内注入药液，药液通过内、外套筒连通的进药口进入药箱；当侧壁的第一进药口211与第二进药口221配合关闭时，底壁的第一进药口211与第二进药口221同时配合关闭，此时完成进药，以保证药箱的密封性良好。内、外套筒配合旋转打开进药口使得不需拧下药箱盖即可通过进药组件20向药箱内直接注入药液，操作方便且快捷，避免药箱盖丢失。
当然，在其他实施例中，也可以采用其它形状的进药口，例如将第一进药口211和第二进药口221设置为圆形，当内套筒22旋转时，第一进药口211与第二进药口221也可以连续实现连通和关闭；或者，也可以采用其它形状的内、外套筒来实现配合旋转，并不以本实施例为限。如图6、图7所示，内、外套筒也可以设置为异形底面，例如将内、外套筒的底部设置为凸起形状，凸起的筒底可增加套筒的侧壁面积，从而设置更多的第一进药口211和第二进药口221，进一步提高进药效率；或者，也可以将内、外套筒的底部设计为圆锥状，并配合相互旋转，也能实现同样的增大进药口的目的。
进一步的，如图1所示，进药组件还包括防护罩23，防护罩23的上端敞口，围绕设置于箱盖本体10的第一开口11的外周，固定于箱盖本体10上。防护罩23底部设有紧固件24，优选的，可采用内嵌螺母的固定柱，配合螺栓，依次从上至下将防护罩23和外套筒21固定于箱盖本体10上。防护罩23的周壁可以避免加入药液时流到药箱盖外，使加药操作更为简单、快捷。
进一步的，如图1所示，防护罩23底部还设有限位组件231；限位组件231包括限位柱2311、活动件2314、第一螺母2312和第一弹性件2313。优选的，限位柱2311采用圆柱形，该限位柱2311可以一体连接在防护罩23上，活动件2314套设在限位柱2311外部，能够沿着限位柱2311上下运动；第一螺母2312固定连接在限位柱2311上端，用以限制活动件2314脱离限位柱2311。第一弹性件2313套设在限位柱2311上，且连接在第一螺母2312与活动件2314内部之间。第一弹性件2313可为弹簧，弹簧的顶部抵紧第一螺母2312，底部抵紧活动件2314。在本实施例中，活动件2314采用上端敞口的阶梯状圆筒，弹簧的底部抵紧活动件2314的内部。当然，在其他实施例中，活动件2314也可以采用其它易于加工的形状来实现与第一螺母2312及第一弹性件2313的活动配合，并不以本实施例为限，例如采用两端开口的圆筒，第一弹簧2313的底部抵紧圆筒的上端，同样可以借助第一弹簧2313的弹力将活动件2314压紧。
进一步的，如图3所示，内套筒22顶端设有第二法兰223，第二法兰223上设有第一腰形孔222，第一腰形孔222两端分别设为第一限位孔2221和第二限位孔2222。如图4所示，防护罩23底部的限位柱2311穿过第一腰形孔222，限位孔的直径略大于活动件2314 底部的周向直径，可使活动件2314底部卡设于第一限位孔2221或第二限位孔2222内，避免内套筒22误转动；而且，限位孔的直径大于第一腰形孔222的宽度，使得限位柱2311能在第一腰形孔222中滑动而活动件2314只能卡设在限位孔内。第一腰形孔222的长度根据第一进药口211和第二进药口221的周向宽度设置，在内套筒22相对于外套筒21转动的过程中，带动第一腰形孔222转动，当活动件2314位于第一限位孔2221或第二限位孔2222内时，分别对应第二进药口221与第一进药口211连通的第一位置和封堵第一进药口211的第二位置，操作简单。
进一步的，如图8所示，内套筒22还设置有旋转把手224。为操作方便，可将该旋转把手224设计为与第二法兰223一体连接的圆柱。注入药液前，限位组件231位于第一腰形孔222的第二限位孔2222内，即内套筒22位于封堵第一进药口211的第二位置，如图5所示的进药组件20全关状态；此时，将活动件2314向上抬起，弹簧受力压缩，活动件2314脱离第二限位孔2222并在第一螺母2312的限制下避免脱离限位柱2311，然后推动内套筒22上的旋转把手224，使内套筒22转动，直至限位组件231位于第一限位孔2221内，再将活动件2314放下，第一弹性件2313的弹力将再次抵紧活动件2314，保证活动件2314卡设在第一限位孔2221内，此时，内、外套筒的进药口完全重合打开，如图4所示的进药组件20全开状态，可以开始进行加药操作。当完成药液注入后，再次重复上述操作，使限位组件231复位至第二限位孔2222内，此时，内、外套筒的进药口完全封闭，保证药箱盖的密封。限位组件231一方面能够避免内、外套筒在不使用的情况下相对转动而使得药箱内的药液流出，另一方面起到快速定位作用，使得内、外套筒的进药口快速封闭或连通。
当然，在其他实施例中，也可以采用其他的结构来实现内套筒22的转动限位，并不以本实施例为限。如图9-图11所示，在外套筒21的第一法兰213上，沿圆周间隔均匀设置有多个向下的第二凸台33，第二凸台33的间隔角度与第一进药口211的间隔角度相同，可使进药口连通时的打开面积最大，以达到最大的进药效率。第二凸台33内安装有波珠定位螺丝32，顶端的活动波珠在受压时会向下挤压弹簧，压力消失时，弹簧的弹力使波珠复位，且螺丝的开口限制波珠脱离螺丝。在内套筒22的第二法兰223上，沿圆周间隔均匀设置有多个第一圆孔31，在内套筒22相对外套筒21旋转的过程中，当第一圆孔31与波珠定位螺丝32重合时，波珠向上弹起，进入第一圆孔31，限制内套筒22继续旋转，此时，内、外套筒的进药口完全重合打开，可以开始进行加药操作；当推动第二法兰223上的旋转把手224时，波珠离开第一圆孔31，受挤压向下压缩弹簧，内套筒22继续旋转，直至下一个第一圆孔31与波珠定位螺丝32重合，此时，内、外套筒的进药口完全封闭。该设计使用波珠定位螺丝32进行限位，结构简单，定位精准，安装省力，轻松达到限位目的。
进一步的，如图1所示，外套筒21底部围绕中心向外凸出有第一凸台212，第一凸台212内嵌设有第二螺母214。所述进药组件20还包括转动组件25，转动组件25由螺杆251、第二弹性件252和垫片253组成。螺杆251底部穿过内套筒22，固定连接于第二螺母214内，第二弹性件252套设于螺杆251外，垫片253固定于螺杆251顶部，用于限制第二弹性件252向上脱离螺杆251。第二弹性件251可为压缩弹簧，其顶部抵紧垫片253，底部抵紧内套筒22。在内套筒22相对于外套筒21转动的过程中，压缩弹簧的压力作用于内套 筒22，避免内套筒22上下运动，从而有利于内、外套筒相对转动。优选的，螺杆251为阶梯状，螺杆251与内套筒22接触段的直径大于螺杆251与第二螺母214连接段的直径，当螺杆251下部的第一阶梯安装在第一凸台212内时，螺杆251的第二阶梯卡设在第一凸台212上方，避免螺杆251随着内套筒22的活动出现松动。当然，在其他实施例中，也可以采用其他的结构来实现内套筒22的上下限位，并不以本实施例为限。例如，如图10所示，在内套筒22的底部中心开设有第二圆孔，外套筒21的底部中心开设第三圆孔，通过第一弹性卡扣34穿过圆孔将内、外套筒的底部进行连接限制。第一弹性卡扣34一端为卡台，另一端为弹性卡爪，使用时，弹性卡爪穿过第一硬垫片35、软垫片36、第二硬垫片37，继而穿过内、外套筒的第二圆孔和第三圆孔后，卡住外套筒21的筒底外表面，此时，卡台下端面通过三层垫片抵住内套筒22的筒底内表面。使用第一弹性卡扣34连接内、外套筒的底部，操作简单，安装快速，限制了内套筒22的上下运动，三层垫片的设计增加连接的弹性，避免影响内、外套筒的相对转动，设计可靠。
实施例二
如图12-图14所示，本发明实施例提供另外一种药箱盖。该药箱盖与实施例一同样具有箱盖本体10、外套筒21、内套筒22、限位组件231和转动组件25，其区别在于：本实施例采用内套筒22固定，外套筒21相对转动的方式实现进药口的连通和封堵。
本实施例中，内套筒22和防护罩23通过紧固件24固定连接在箱盖本体10的第一开口11处，内套筒22的第二法兰223上设有第二腰型孔38和第三腰形孔39，其中第二腰形孔38具有第三限位孔381和第四限位孔382，用于外套筒21的旋转定位，第三腰形孔39用于安装内、外套筒的转动连接件。外套筒21的第一法兰213上设置有限位组件231，该限位组件231穿过第二腰型孔38，并带动外套筒21沿第二腰型孔38滑动，当活动件2314卡设在第三限位孔381内时，如图12、图13所示，内、外套筒上的第一进药口211和第二进药口221连通，此时可以进行加药操作；当活动件2314卡设在第四限位孔382内时，如图14所示，外套筒21将内套筒22的第二进药口221封堵，此时药箱盖密封；第二弹性卡扣41穿过第三腰形孔39，固定于外套筒21的第一法兰213上，既可以保证外套筒21转动过程的流畅，又能避免外套筒21的上下窜动。
当然，在实施例一中所述的其它限位方式、其他进药口形状或者其它转动组件等结构，也可以结合应用到本实施例中，并不以本实施例为限。
实施例三
本实施例提供一种无人机，包括设置有实施例一或实施例二中的药箱盖的药箱。该无人机用药箱可实现加药时无需手动拧下药箱盖，只需要旋转内套筒或者外套筒，使得内、外套筒的进药口相通即可直接通过进药组件向药箱内注入药液；进药组件设有限位装置，能够快速有效地完成内、外套筒旋转到位，且能够避免作业过程中误操作打开进药口，方便、高效且可靠；该药箱盖可以单独生产，对应适配多型号的药箱，更为经济可行。
显然，本发明的上述实施例仅仅是为了清楚说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，能够进行各种明显的变化、重新调整和替代而不会脱离本发明的保护范围。这里无需也无法对所有的实施方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
