Description

喷洒系统及农业无人机 技术领域
本发明属于无人机技术领域，涉及一种喷洒系统及农业无人机。
背景技术
现有技术中，农业无人机在飞行过程中可进行液体的喷洒作业，如农业无人机喷洒农药进行除虫作业等。在农业无人机上设有容纳液体的水箱及将对外喷洒的液体进行增压的泵体组件。其中，泵体组件固连在水箱或无人机的机身上。
农业无人机对大规模的农作物进行喷洒作业时，农业无人机单次携带的液体量不足以完成全部的喷洒作业。在将水箱内的液体喷洒完后，需要将空水箱自无人机的机身上拆卸并更换一装满液体的水箱，以提高农业无人机的作业效率。因而，泵体组件需要与空水箱分开并连通至另一装满液体的水箱。
在农业无人机完成喷洒作业后，需要将泵体组件拆卸下来以进行清洗作业，避免腐蚀性的液体滞留于泵体组件内。相应地，泵体组件与水箱或机身接触装配关系，通常，该装配关系为紧固件锁定连接，或水泵直接于水箱固定连接。导致现有的泵体组件拆卸复杂度高，拆卸效率低，用户体验差。
发明内容
有鉴于此，本发明的目的之一是提供一种喷洒系统及农业无人机。
根据本发明实施例的第一方面，提供一种喷洒系统，包括水箱和泵体组件，所述泵体组件通过导管连通至所述水箱，所述喷洒系统还包括用于可拆卸连接所述泵体组件的装配框，其中，所述泵体组件卡箍于所述装配框内，所述装配框可拆卸地安装在所述水箱外，以使所述泵体组件挂设于所述水箱外。
根据本发明实施例的第二方面，提供一种农业无人机，包括机架和喷洒系统，所述喷洒系统包括水箱和泵体组件，所述泵体组件通过导管连通至所述水箱，所述喷洒系统还包括用于可拆卸连接所述泵体组件的装配框，其中，所述泵体组件卡箍于所述装配框内，所述装配框可拆卸地安装在所述水箱外，以使所述泵体组件挂设于所述水箱外，所述水箱固连于所述机架。
本发明的实施例提供的技术方案可以包括以下有益效果：
泵体组件卡箍于装配框内，两者通过配合连接实现互相定位，便于泵体组件与装配框之间拆卸和安装。泵体组件通过装配框挂设于水箱外，其与水箱之间仅仅通过导管连通，在拆除导管后即可与水箱分离，泵体组件拆装方便。装配框与水箱可拆卸安装，将装配框从水箱脱开，可使水箱从机架上拆卸，或者装配框协同泵体组件从水箱上拆除，或者泵体组件可独立从装配框上拆卸下来。喷洒系统可相应的更换部件，应用灵活，用户体验好。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，根据一示例性实施例示出的一种农业无人机。该农业无人机包括机架200和安装于机架200的喷洒系统100，喷洒系统100的 水箱30固连于机架200，机架200飞行带动喷洒系统100沿飞行路线进行喷洒作业。
在一实施例中，机架200包括中心体201以及与中心体201连接的多个脚架202，水箱30位于多个脚架202之间，并且与脚架202可拆卸连接。中心体201用于带动水箱30及泵体组件20等飞行，并在预设区域进行喷洒作业。水箱30于脚架202可拆卸连接，便于水箱30内的液体喷洒完成后及时进行更换作业，提高喷洒作业效率。
如图2至图4所示，在一实施例中，喷洒系统100包括水箱30和泵体组件20，泵体组件20通过导管40连通至水箱30，水箱30内收纳有待喷洒的液体，该液体沿导管40输出至泵体组件20，泵体组件20运行并将液体进行压力调整后输出。
为便于将泵体组件20固定于水箱30上，喷洒系统100还包括用于可拆卸连接泵体组件20的装配框10，其中，泵体组件20卡箍于装配框10内。装配框10可拆卸地安装在水箱30外，以使泵体组件20挂设于水箱30外。泵体组件20与装配框10可拆卸安装，如装配框10卡箍于泵体组件20外并与泵体组件20之间互相弹性挤压连接；或装配框10卡箍于泵体组件20外并与泵体组件20之间卡扣连接等。
泵体组件20卡箍于装配框10内，两者通过配合连接实现互相定位，便于泵体组件20与装配框10之间拆卸和安装。泵体组件20通过装配框10挂设于水箱30外，其与水箱30之间仅仅通过导管40连通，在拆除导管40后即可与水箱30分离，泵体组件20拆装方便。装配框10与水箱30可拆卸安装，将装配框10从水箱30脱开，可使水箱30从机架200上拆卸，或者装配框10协同泵体组件20从水箱30上拆除，或者泵体组件20可独立从装配框10上拆卸下来。喷洒系统100可相应的更换部件，应用灵活，用户体验好。
装配框10可拆卸安装于水箱30。在一实施例中，装配框10插接并挂 设于水箱30外。将装配框10与水箱30插接连接，并通过两者的插接部分相互配合，使得装配框10和泵体组件20挂设于水箱30外。其中，装配框10插入水箱30的部分倒扣于水箱30的连接部15位，以避免装配框10与水箱30分离。
在一实施例中，水箱30包括用于容纳液体的箱体件31及固连于箱体件31的固定支架32，箱体件31为中空的容器结构，其中，固定支架32固定于箱体件31的外侧壁上。导管40的第一端连接至箱体件31，导管40的第二端连接至泵体组件20。导管40将箱体件31的液体引导至泵体组件20，通过泵体组件20向外输出预设压力的液体。其中，装配框10插接连接至固定支架32，且装配框10插入固定支架32的部分挂设于固定支架32上，以使泵体组件20及装配框10挂设于水箱30上。
装配框10卡箍于泵体组件20外，其中两者的接触面可设为刚性接触或弹性接触。在一实施例中，装配框10与泵体组件20之间的接触部位为弹性接触。在装配框10与泵体组件20的卡箍部分具有弹性力，两者的安装紧密度高，相对位置稳定。进一步的，装配框10与泵体组件20弹性接触，可避免装配框10与泵体组件20之间具有安装间隙及互相之间挤压力而损坏泵体组件20或装配框10。
装配框10与泵体组件20之间弹性接触，可包括一下形式：
一、装配框10整体或局部由弹性材料制成，以使装配框10与泵体组件20弹性卡箍连接。
二、装配框10由刚性材料制成，泵体组件20设有弹性层，该弹性层由弹性材料制成。装配框10卡箍于弹性层外，以实现两者的弹性卡箍连接。
调整装配框10或泵体组件20之间弹性材料所分布的区域，以实现装配框10弹性卡箍于泵体组件20外。泵体组件20与装配框10之间的装配方便，两者弹性挤压，可以提高安装位置的稳定性，及提高喷洒系统100作业 过程中泵体组件20的减震效果，避免两者松动。
以下以装配件弹性卡箍于泵体组件20外为例进行示例性说明，在不冲突的情况下，下述实施例之间可以相互组合。
如图5所示，装配件弹性卡箍于泵体组件20外，在一实施例中，装配框10设有与泵体组件20相匹配的容纳空间11。该容纳空间11由贯穿装配框10的孔状结构形成的空间；或自装配框10表面凹陷形成的凹槽结构形成的空间；或容纳空间11由贯穿装配框10的孔状结构与罩设于孔状结构一端的罩设部分相结合形成的空间。泵体组件20插设至容纳空间11，以使装配框10弹性卡箍于泵体组件20外。
装配框10包括主体部12，容纳空间11贯穿主体部12。可选地，主体部12呈板状结构，容纳空间11由贯穿主体部12的孔状结构形成的空间。部分泵体组件20沿容纳空间11穿过主体部12，主体部12弹性卡箍于泵体组件20的外周壁。在泵体组件20穿插过程中，主体部12向外弹性扩张。当泵体组件20穿插至预设位置时，主体部12卡持于泵体组件20的外周壁上，以使泵体组件20被装配框10所弹性卡箍。
容纳空间11的形状与泵体组件20的配合部位相适配，如容纳空间11设于矩形状、椭圆状、圆形等空间，泵体组件20穿插至容纳空间11内且被主体部12所卡箍。为限定泵体组件20的安装位置，避免泵体组件20相对于装配框10移动。在一实施例中，主体部12设有自表面凹陷形成的至少一限位部13，限位部13用于限定泵体组件20的安装位置。限位部13位于主体部12，其与泵体组件20上的凸出部位相对应，如限位部13为设于主体表面的凹槽，该凹槽与容纳空间11连通。泵体组件20设有凸出表面的凸台。泵体组件20沿容纳空间11穿过主体部12，并使凸台陷入限位部13中，以限制泵体组件20继续移动，限位部13还限制泵体组件20的转动，以使泵体组件20与装配框10配合定位，泵体组件20的安装准确度高。
容纳空间11用于安装和限定泵体组件20，进一步的，为调整泵体组件20的安装数量或安装位置。在一实施例中，主体部12设有至少一间隔部14，间隔部14位于容纳空间11内，以将容纳空间11间隔成若干安装空间。泵体组件20对应安装至相应的安装空间，使泵体组件20的部件独立安装，如泵体组件20包括两个水泵21时，每一水泵21可对应安装至一个安装空间。在需要对其中一水泵21进行拆卸时，仅需将相应的水泵21从装配框10中拆下，另一水泵21保持安装于装配框10上，更换方便，操作性好。
装配框10与水箱30插接连接，以使装配框10及泵体组件20挂设于水箱30上。在一实施例中，装配框10包括凸出主体部12的连接部15，连接部15与水箱30插接连接，以使装配框10挂设于水箱30。连接部15局部凸出主体部12的表面，该连接部15插接连接至水箱30的相应位置，以使装配框10挂设于水箱30上。
如图5和图6所示，在一实施例中，连接部15包括自主体部12表面向外延伸形成的滑动柱151及设于滑动柱151端部的卡持部152，卡持部152的外径大于滑动柱151的外径。卡持部152沿第一方向穿插至水箱30内，卡持部152沿第二方向移动，卡持部152的两侧抵靠至水箱30的侧壁，其中，第一方向与第二方向倾斜相交。
连接部15的截面呈“T”字形结构，连接部15插接至箱体，卡持部152沿第一方向向水箱30方向穿插至水箱30的预设位置，并沿第二方向移动，使卡持部152倒钩卡持于水箱30上。滑动柱151延伸至主体部12，以使主体部12及安装于主体部12的泵体组件20挂设于水箱30上。
相应地，连接部15插接连接至固定支架32，在一实施例中，固定支架32包括本体部322和开设于本体部322的至少一滑槽孔321，滑槽孔321的形状与装配框10的连接部15的形状相匹配。部分装配框10穿过至少一滑槽孔321并沿滑槽孔321滑动，该部分装配框10抵靠至本体部322。或该部分装配框10抵靠至本体部322与箱体件31，以使装配框10挂设于水箱30。
连接部15的卡持部152沿第一方向穿插至滑槽孔321，并沿滑槽孔321的第二方向滑动，直至卡持部152的两侧受限于滑槽孔321两侧的本体部322壁面，以使装配框10挂设于固定支架32。在又一实施例中，卡持部152的第一侧端面抵靠至本体部322两侧的壁面上，卡持部152的第二端面部分抵靠至箱体件31，以使卡持部152的两侧端面均受限于水箱30，改善装配框10的受力情况，挂设效果好。
滑槽孔321用于引导及限制连接部15。在一实施例中，滑槽孔321包括大孔端3211、小孔端3213、分别连接大孔端3211与小孔端3213的第一连接边3212和第二连接边，大孔端3211的孔径大于小孔端3213的孔径。部分装配框10自大孔端3211穿过固定支架32并沿第一连接边3212和/或第二连接边向小孔端3213方向滑动，装配框10抵靠于第一连接边3212和第二连接边两侧的本体部322。
装配框10的卡持部152沿大孔端3211穿过固定支架32并沿第一连接边3212和/或第二连接边向小孔端3213方向滑动，其中，卡持部152的外径大于小孔端3213的孔径，小于大孔端3211的孔径。第一连接边3212和/或第二连接边可以为相互平行的两条边，也可以为相对倾斜的两边。滑动柱151沿第一连接边3212和/或第二连接边滑动并卡持于第一连接边3212和第二连接边或卡持于小孔端3213。卡持部152限定于第一连接边3212和第二连接边两侧的侧壁上，不能从小孔端3213拔出，装配框10的安装方便。装配框10从固定支架32上拆卸时，仅仅需要控制装配框10反向移动，以使卡持部152从大孔端3211抽出，拆卸方便。
为了便于控制装配框10避免绕滑槽孔321转动。在一实施例中，固定支架32包括间隔设置的两滑槽孔321，装配框10与两滑槽孔321插接连接。在固定支架32设置两滑槽孔321以确定装配框10的安装位置，定位准确。如将两滑槽孔321水平间隔分布于固定支架32上，相应地，在主体部12的一侧边上局部凸出形成两连接部15，该连接部15的间距与两滑槽孔321的间 距相等。当装配框10安装至固定支架32时，两连接部15同时插接连接至固定支架32，以使装配框10挂设于水箱30上，安装位置稳定性好。
继续参见图5所示，箱体件31包括呈容器状的水箱本体311和穿插至水箱本体311的出液管组件312，出液管组件312用于将水箱本体311内的液体引导至外部。导管40的第一端连接至出液管组件312，导管40的第二端连接至泵体组件20。其中，泵体组件20在增压输出液体并在导管40的第二端连接的进水口212一端产生压力差，以使得水箱本体311内的液体通过出液管组件312及导管40进入到泵体组件20。
导管40连通至泵体组件20以形成液体流动的回路，导管40固定于出液管组件312上，将导管40从泵体组件20上拆除后，泵体组件20和水箱30组件两者分离，可以进行独立的拆卸及更换作业。两者的关联性小，拆卸效率高。
出液管组件312为水箱本体311内液体流出的部件。在一实施例中，出液管组件312包括凸设于水箱本体311的管体3121和盖设于管体3121开口处的管盖3122，导管40的第一端固设于管盖3122且与管体3121导通。管体3121为导通水箱本体311内部与外部的连接部15位，其与水箱本体311可设于一体结构，如水箱本体311与管体3121一体成型，水箱本体311局部凸出形成管状的管体3121。或者管体3121与水箱本体311为分体结构，水箱本体311设有出液口，管状的管体3121装配至水箱本体311，以使出液口与管体3121导通。管体3121设置独立装配至水箱本体311，可调整管体3121的形状及调整导管40与管体3121的连接部15位，改善液体流动的效果。
管盖3122封闭于管体3121的出口端，导管40固连于管盖3122上并与管体3121导通。其中，导管40可设为一路或多路管路输出。管盖3122可设于一体结构，卡扣或螺旋连接至管体3121。在一实施例中，管盖3122设为分体结构，包括呈环形的螺旋件31222和放置于螺旋件31222内的端盖件31221，导管40固定于端盖件31221上。螺旋件31222螺纹连接于管体3121 上并带动端盖件31221密封抵接至管体3121的端部。可选地，在端盖件31221与管体3121之间可设一弹性密封圈。管盖3122设为分体结构，可使管盖3122旋转过程中，导管40不随管盖3122旋转，安装方便。
管体3121用于引导水箱本体311内的液体输出，为将水箱本体311内的液体尽量大的输出。在一实施例中，管体3121位于水箱本体311重力方向所处的最低位置。该最低位置为水箱本体311的中心下方；或者管体3121倾斜延伸至水箱本体311内部底壁的中心处；或者水箱本体311底壁向管体3121的的出口方向倾斜，以使得液体在重力作用下汇聚至管体3121的出口处，避免滞留于水箱本体311内。通过调整管体3121的位置可引导水箱30内的液体汇聚于管体3121处并输出，水箱30的空间利用率高。
为提高泵体组件20的使用寿命并降低故障率，在一实施例中，出液管组件312还包括穿插于管体3121内的滤网件3123，滤网件3123用于过滤水箱本体311流入导管40的液体。水箱本体311内的液体在添加或调制，甚至在原料中会存在杂质。在管体3121内设置滤网件3123用于过滤固体杂质，可提高泵体组件20的使用寿命。
其中，滤网件3123包括第一滤芯和插设于第一滤芯的第二滤芯，其中，第一滤芯导管40卡接。管盖3122封闭至管体3121并推抵滤网件3123限定于导管40内。滤网件3123呈筒体状，其开口端环绕导管40，以使流入管体3121的液体经过滤网件3123过滤。
继续参见图5所示，泵体组件20用于调整液体的输出压力。在一实施例中，泵体组件20包括至少一水泵21，至少一水泵21对应插设连接至装配框10，装配框10卡箍于水泵21的外表面。每一水泵21对应插接连接至装配框10的安装空间，其中，装配框10的主体部12对应卡箍于每一水泵21的外表面。以使得每一水泵21均能独立固定，相应地，在更换其中一水泵21时，其可将相应的水泵21从装配框10中拆卸下来，更换方便。
当水泵21与装配框10弹性卡箍时，水泵21插接连接至装配框10时，两者弹性挤压定位，改善缓冲及卡箍效果。在一实施例中，水泵21包括至少部分表面凸出或凹陷形成的至少一卡箍部211，装配框10弹性卡箍于卡箍部211。卡箍部211的外表面设有弹性层或者装配框10与水泵21的卡箍部211位由弹性材料制成。该卡箍部211用于配合装配框10定位，可选地，在卡箍部211上设有用于限定水泵21安装位置的凸台，该凸台与装配件的限位部13相互匹配，以限定水泵21的安装角度及安装高度。
导管40连接至水泵21，并且水泵21将液体改变输出压力后将液体输出，以完成液体的循环。在一实施例中，水泵21包括一进水口212和一出水口213，导管40连接至进水口212，其中，导管40与进水口212通过螺母件41锁紧连接。泵体组件20还包括连接至至少一水泵21的分路管道件22，分路管道件22与出水口213连接。
导管40的第二端安装有螺母件41，该螺母件41套设于导管40外。将螺母件41螺纹连接至进水口212，以使导管40的第二端密封抵接于进水口212上。可选地，在导管40的第二端与进水口212之间可设置密封圈等密封结构。螺母件41螺旋连接至出水口213以实现导管40与水泵21的连接，安装快速。相应地，将螺母件41松开，导管40可从水泵21上拆除，以更换水泵21或更换水箱30，水泵21及水箱30的更换方便。
水泵21与分路管道件22连接，其中，两者可通过导管40与螺母件41的配合结构连接，也可使分路管道件22直接连接于水泵21的出水口213上。分路管道件22可连接至安装于中心体201的喷头组件203，以进行喷洒作业。
通过拆卸导管40及装配框10可实现泵体组件20与水箱30的快速拆分，其拆卸效率高，更换方便。水箱30的液体通过导管40及出液管组件312输送至泵体组件20，并经分路管道件22输送至喷头组件203，以进行喷洒作业，作业效率高。
