现有的割草机机架采用一体式结构,前后轮的轴距固定,安装在机架的底部的割台组件,因为轴距受限而不能根据工作环境更换合适的规格。本申请的机架为分体式机架,前部机架与后部机架可拆卸式固定安装,不同规格的割台组件对应不同规格的前部机架,前轮组件安装在前部机架上,当需要更换割台组件以满足使用要求时,首先选择合适规格的前部机架与后部机架进行固定,保证割台组件具有合适的安装尺寸,再将需要额更换的割台组件安装在机架上,使得在不同工作环境下,可以更换适配的割台组件,满足多种环境的使用要求。本申请的相适配的割台组件与前部机架也可以始终处于相对连接状态,一方面减少寻找部件的时间,另一方面节约装配工序,提高更换效率。

请参阅图1~图4,本申请提供一种割草机,割草机包括有机架100、行走机构200、割台组件300。
请参阅图12、图16,图12、图16示出了两示例性机架100结构,机架100包括有前部机架110、后部机架120,前部机架110与后部机架120可拆卸连接,其中前部机架110安装有前轮组件210、后部机架120安装有后轮组件220。作为优选,前部机架110与后部机架120通过连接螺栓122进行安装固定。前轮组件210单独装配在前部机架110上,电池、控制组件等装配在后部机架120上,当需要更换不同规格的割台310时,如48寸、52寸、60寸等,割草机通过更换适配的前部机架110,改变了割草机的轴距,从而保证了割台310可以进行装配。
一示例性实施例中,割台310装配在割草机上后,割台310位于前轮和后轮之间,割台310与前轮的最近距离为10~60mm,割台310与后轮的最近距离为10~60mm,割台310与前轮、后轮均保持合适的距离,一方面是便于割台310进行高度的调节,另一方面是在颠簸等恶劣工作环境中,割台310会产生轻微的前后晃动,与前轮、后轮保持一定的距离,避免割台310与前轮、后轮发生碰撞,减少割草机受损风险。

需要更换不同规格的割台310时,前部机架110需要进行先行更换,若割草机无需更换的部件安装在前部机架110上,那必然增加拆装的工作量,本申请一实施例中,割草机的大部分部件安装在后部机架120上,如电池、控制系 统、驾乘座椅500或站立区等。
请参阅图14,图14示出了一示例性后部机架120结构,后部机架120上设有第一安放区123,第一安放区123设置于驾乘座椅500的下方,向前延伸至踩踏区510后端,向后延伸至机架100尾端,第一安放区123内固定电池。电池为割草机提供电能,不同规格、不同要求的割草机需要根据需要安装合适的电池。作为优选,第一安放区123的底板设有若干的第一安装孔1231,不同规格的电池匹配不同位置的第一安装孔1231,从而实现不同规格电池的安装固定,满足不同的使用要去。需要说明的是,形式不同的割草机第一安放区123位置不同,如站立式割草机,第一安放区123设置在后部机架120靠近前部机架110的位置,电池重量较大,放置在靠前的位置,可以平衡人员站立在割草机后端带来的力,提高割草机的稳定性,避免人员靠后站立时割草机发生倾覆。如坐骑式割草机,工作人员是坐在割草机的顶面,为了降低割草机的重心,第一安放区123可以设置在驾乘座椅500的下方,可以降低割草机的重心,提高割草机移动平稳性,提高割草机的爬坡性能。对于第一安放区123的设置位置,根据实际情况进行选择,本申请对此不做限定,满足电池的安放需要即可。还需要说明的时,一个第一安放区123可以仅安放一个电池,也可以安放多个电池,多个电池之间可以并联或串联,电池可以同时供能,也可以一块使用电量耗尽后再使用第二块电池,本申请对此不做限定,根据实际需要进行选择。一优选实施例中,电池800安装于第一安放区123后,电池800上表面到地面距离小于610mm,电池包800的重心与前轮组件210或后轮下边缘之间的距离小于480mm,更进一步,电池包800的重心与前轮组件210或后轮下边缘之间的距离为360-460mm。电池800的重心与后轮的转动中心之间的距离小于400mm,电池800的重心到前轮组件210的转动中心之间的距离是电池800重心与后轮转动中心之间距离的2到4倍。在本实施例中,电池800的安装高度更低,电池800的重心更低,降低了割草机的重心,使得整机行驶时更加稳固可靠,同时,降低了操作者的乘坐高度,也一定程度上降低了整车的高度。一优选实施例中,割草机的最大高度小于2000mm,进一步地,割草机的高度为1700~1900mm,例如1841mm,宽度优选为1700~2100mm,例如为1867mm,割草机长度优选为1600~2200,例如为长度1874mm。一实施例中,割草机的重心与后轮轴线之间的距离244~444mm,距离可以为244~444mm之间的任意数值,如244mm、300mm、344mm、444mm等,优选的,割草机的重心与后轮轴线之间的距离259~429mm,可以为259~429mm之间的任意数值,如259mm、344mm、385mm、400mm、729mm等。示例性的,割草机的重心在前轮轴线与后轮轴线之间的65~81%处,可以为65~81%之间的任意数值,如65%、71%、73.5%、81%等,割草机的重心靠近后轮;优选的,割草机的重心在前轮轴线和后轮轴线之间的67%~80%之间,可以为67%~80%之间的任意数值,如67%、69%、73.5%、80%等,割草机的重心靠近后轮。

请参阅图38,示例性的,切割部320安装在割台310上,包括有切割电机321、以及切割电机321驱动的切割刀322,切割刀322对草进行切割,切割刀322与地面的高度即为草地需要的高度,在一实施例中,一个切割电机321驱动一个切割刀322,在另一实施例中,切割电机321通过传动机构同时驱动多个切割刀322,本申请对此不做限制。割台310的底部设有切割挡板330,切割挡板330阻止切割下的草屑飞溅。切割挡板330的侧面或后面设有排草口340,排草口340上设有转动连接在割台310上的排草罩341。需要说明的是,在其他实施例中,切割电机321可以直接安装在机架100上或其他合适的位置。
请参阅图21~23,调高装置350用于调整切割刀322与地面的高度,从而获得合适的高度以满足不同草地的需要。调高装置350调节高度时,调节割台组件300整体的离地高度,一方面可以满足不同草地的割草需要,另一方面,当遇到路面不平或有障碍物时,割台组件300保持较高的离地高度,可以避开障碍物,具有更好的地形通过能力。调高装置350包括有与机架100转动连接的第一连接杆351、第二连接杆352,第一连接杆351、第二连接杆352均有两个,分设在机架100的两侧。第一连接杆351、第二连接杆352分别与割台310转动连接,第一连接杆351与第二连接杆352通过第三连接杆353连接,第三连接杆353与第一连接杆351、第二连接杆352均转动连接。第三连接杆353与割台310分设于第一连接杆351的两侧,第三连接杆353与割台310分设于第二连接杆352的两侧,转动第一连接杆351或第二连接杆352即可带动割台310上升或下降,从而进行割台组件300高度的调节。作为优选,两个第一连接杆351之间或两个第二连接杆352之间相对固定,使得调高装置350的两侧可以同步调节,保持割台组件300的稳定。一实施例中,两个第一连接杆351通过一固定杆连接,固定杆与两个第一连接杆351均保持固定连接,实现两个第一连接杆351之间的相对固定。在一实施例中,固定杆作为第一连接杆351与机架100的转动轴,既实现了两个第一连接杆351之间的固定,又避免第一连接杆351转动时固定杆出现位移,节约了装配、使用空间。
示例性的,第一连接杆351通过转动轴与机架100转动连接,第一连接杆351与机架100的转动轴轴线为第一轴线,第二连接杆352通过转动轴与机架100转动连接,第二连接杆352与机架100转动轴轴线为第二轴线,第一轴线与第二轴线的连线为第一线段,第一线段分别垂直于第一轴线、第二轴线;一连接杆351通过转动轴与第三连接杆353转动连接,第一连接杆351与第三连接杆353的转动轴轴线为第三轴线,第二连接杆352通过转动轴与第三连接杆353转动连接,第二连接杆352与第三连接杆353的转动轴轴线为第四轴线,第三轴线与第四轴线的连线为第二线段,第二线段分别垂直于第三轴线、第四轴线;第一连接杆351通过转动轴与割台310转动连接,第一连接杆351与割台310转动轴轴线为第五轴线,第二连接杆352通过转动轴与割台310转动连接,第二连接杆352与割台310的转动轴轴线为第六轴线,第五轴线与第六轴线的连线为第三线段,第三线段分别垂直于第五轴线、第六轴线;第一线段、第二线段、第三线段平行且长度相等,保证在升降过程中,割台310始终处于水平,保证切割刀322水平,从而获得良好的割草效果。
请参阅图21,示例性的,第一连接杆351上设有脚踩杆354,脚踩杆354设置于第一连接杆351远离割台310的一端,使用人员通过脚踩可以升起割台组件300,抬脚割台组件300受重力下落,相较于用手,用脚操作更加快捷方便。尤其是对于坐骑式割草机,使用人员坐在割草机上就可以对割台组件300的高度进行调节,非常的便捷。需要说明的是,脚踩杆354可以为杆状、板状、块状等适合踩踏的结构,具体结构不作限定。
作为优选,脚踩杆354的表面的设有防滑结构,如表面设置防滑纹路、套设防滑垫等,根据实际情况选择合适的防滑结构,对此本申请不做赘述。
请参阅图21,不同使用人员的身高、腿长不同,为了便于不同的人员进行操控,本申请一实施例中,第一连接杆351远离台架的一端设有若干脚踏安装孔3541,脚踩杆354可以固定在不同的脚踏安装孔3541上,实现脚踩杆354位置的调节,满足不同人员的不同使用要求。脚踩杆354与第一连接杆351可拆卸连接,可以为脚踩杆354的端部设置外螺纹,脚踏安装孔3541为螺纹孔,脚踩杆354与脚踏安装孔3541直接螺纹连接;也可以为脚踩杆354端部设有螺纹孔,通过螺栓贯穿脚踏安装孔3541与脚踩杆354螺纹配合实现固定;也可以为脚踩杆354端部为设有外螺纹台阶,脚踩杆354台阶处贯穿脚踏安装孔3541后通过螺母固定,根据实际需要进行选择合适的连接手段,本申请对此不做限定。
示例性的,为了方便进行割台组件300的升降操作,第一连接杆351与机架100转动轴靠近割台310,即脚踩杆354到转动轴的距离,大于割台310到转动轴的距离。根据杠杆原理,使用人员调节割台组件300的高度时,仅需要对脚踩杆354施加较小的力即可实现割台组件300的高度调节,使用人员操作更方便、更节约用力。
请参阅图30,图30为本申请图4中E区域放大图,示出了一示例性锁定装置。在调节切割刀322离地高度后,需要锁定装置360对割台组件300进行锁定,保证始终保持合适的切割高度。锁定装置360包括有卡位板361、限位板362,卡位板361设置在调高装置350上,如第一连接杆351、第二连接杆352、第三连接杆353等位置,优选卡位板361固定在第三连接杆353上。第三连接杆353设置在机架100的两侧,为了方便使用,卡位板361设置在与脚踩杆354同侧的第三连接杆353上,向机架100伸出。限位板362固定在机架100上,限位板362上设置有若干的限位孔3621,限位孔3621内配合有限位杆363。
一实施例中,为了方便进行高度调节,向前踩踏脚踩杆354时,割台组件300升起,即卡位板361向前移动时,割台组件300升高,割台组件300降低时,卡位板361向后移动。为了对割台组件300高度进行锁定,限位杆363设置于卡位板361的后方,在割台组件300重力的作用下,卡位板361有向后移动的趋势,通过限位杆363与限位板362的配合,限制卡位板361向后移动,从而限制割台组件300向下移动,对割台组件300的高度进行锁定。
限位杆363与限位孔3621插拔连接,当限位杆363拔出后放置到一旁容易丢失。本申请一实施例中,通过绳子将限位杆363与机架100或割草机的其他部件进行柔性连接,避免限位杆363拔出后丢失。
在工况严峻、颠簸的情况下,存在限位杆363掉出限位孔3621的风险,也存在工作人员将限位杆363误拔出,导致割台组件300突然下落的情况。一实施例中,限位孔3621的边缘设有突出的卡孔3622,限位杆363的侧壁设有卡块,卡块与卡孔3622相配合。卡块与卡孔3622位置对应时,限位杆363可以拔出或插入限位孔3621,为了避免限位杆363由限位孔3621内脱落,限位杆363插入到限位孔3621内后,对限位杆363进行转动,使得卡块与卡孔3622位置不对应,此时限位杆363不能直接拔出,可以有效降低限位杆363由限位孔3621内脱落的风险,也可以降低使用人员误拔限位杆363的风险。
为了有效的对卡位板361进行锁止,请参阅图30,一实施例中,限位板362设有上下两层,两层限位板362上的限位孔3621位置相同,限位杆363依次贯穿两层限位板362的限位孔3621。卡位板361设置于两层限位板362之间,由此限位杆363的两端均由限位板362进行支撑,避免卡位板361挤压限位杆363时,限位杆363因上下两端受力不均而倾斜的问题出现。
请参阅图32,一实施例中,卡位板361与限位杆363接触的一侧设有若干卡位台阶364,限位孔3621错位排布,在割台组件300调节总高度不变的情况下,增加割台组件300锁止数量,获得对割台组件300高度进行更准确的调节。
请查阅图31,图31为本申请图21中F区域放大图,示出了一示例性自锁机构370。割台组件300包括有自锁机构370,自锁机构370包括有自锁杆371、自锁件372,其中自锁件372与机架100转动连接,自锁件372上设有自锁槽373,自锁件371滑入自锁槽373后,自锁杆371与自锁槽373配合限制割台组件300向下移动。在进行割台组件300高度调节的过程中,需要使用人员始终保持割台组件300提升的状态,对于使用人员不熟悉调节高度等情况,始终保持割台组件300提升状态会非常浪费体力。通过自锁杆371与自锁槽373配合,可以将割台组件300限制在较高的高度,减少割台组件300高度调节过程中,使用人员浪费体能在保持割台组件300提升状态上。在割草机非工作状态移动时,也需要将割台组件300提升到高位,避免切割刀322碰撞受损,自锁机构370可以保持割台组件300在高位。
一实施例中,自锁件372靠近自锁杆371的一侧为倾斜面,倾斜面自下而上向自锁杆371方向倾斜,自锁槽373设置在倾斜面上,自然状态下,自锁槽373开口向下。倾斜面的设置可以保证割台组件300在提升过程中,自锁杆371向前向下移动,不会被自锁件372限制移动,自锁杆371也更顺利进入到自锁槽373内。自锁件372通过转动轴绕机架100转动,自锁杆371向前向下移动过程中,自锁件372绕转动轴转动,直至自锁杆371滑入到自锁槽373内,此时释放割台组件300,自锁槽373限制自锁杆371向后移动,使得割台组件300保持在高位。
一实施例中,自然状态下,自锁件372在自身重力作用下有向自锁杆371方向转动的趋势,通过在机架100上设置限止装置,避免自锁件372向自锁杆371方向转动。限止装置可以为限止杆、限止块等防止锁板向自锁杆371方向转动的结构,一实施例中,限位板362向机架100外侧伸出,自锁件372的底部设有远离自锁杆371方向的凸起375,凸起375位于限位板362的下方,通过凸起375接触到限位板362的底部,限制自锁件372向自锁杆371方向转动。一实施例中,为了便于安装,保证自锁件372安装的牢固度,限位板362底部设有向下的延伸板,以使得凸起375不高于自锁件372与机架100的转动轴,自锁件372安装在机架100的中部。请参阅图17,一实施例中,为了避免自锁杆371进入自锁槽373时,自锁件372转动受限。自锁件372上设有弯折部376,弯折部376使得自锁件372的上部远离机架100,自锁件372向远离自锁杆371转动时不受限。为了便于将自锁杆371由自锁槽373内释放,自锁件372上设有手持部374,手持部374方便持握自锁件372,可以通过手持部374处转动自锁件372实现自锁杆371的释放。作为优选,自锁件372呈V形,手持部374与自锁槽373设置在V形的两侧。
自锁杆371可以设置在第二连接杆352、第三连接杆353等部件上,一实施例中,自锁杆371设置于第二连接杆352与第三连接杆353的转动轴处,作为优选,第二连接杆352与第三连接杆353的转接轴作为自锁杆371,实现一个部件的两种用途。割台310受到向下的重力作用,有向下移动的趋势,带动第二连接杆352与第三连接杆353的转动轴有移动的趋势,自锁杆371插入到自锁槽373内,自锁杆371移动会使得自锁件372转动趋势,而由于自锁件372凸起375与限止装置配合,限止了自锁件372的转动,使得自锁杆371无法产生移动,从而实现了割台310的自锁,限制割台310向下移动。
割台组件300还包括有缓冲装置390,一实施例中,缓冲装置390为缓冲弹簧,缓冲弹簧的一端与机架100相固定,另一端与非锁定装置360侧的调高装置350相连接,作为优选,缓冲弹簧的另一端挂在第三连接杆353与第二连接杆352的转动轴上,缓冲装置390作用于调高装置350的作用力与割台组件300作用于调高装置350的作用力相反。当遇到颠簸区域割台组件300晃动时,通过缓冲装置390可以对割台组件300进行缓冲,降低割台组件300的晃动幅度。在另一实施例中,缓冲装置390可以是多个缓冲弹簧,也可以为一个或多个其他弹性缓冲件,缓冲装置390连接在机架100与割台组件300之间,具体连接位置不做限定。
一实施例中,第一连接杆351远离第三连接杆353的一端转动有第四连接杆355,第二连接杆352远离第三连接杆353的一端转动有第五连接杆356,第四连接杆355与第五连接杆356均与割台310转动连接,第一连接杆351与第二连接杆352不直接与割台310转动连接。割台310的顶部转动连接有第一连接板357,第一连接板357的另一端转动连接在机架100底部。通过设置第一连接板357,可以增加割台组件300的连接稳定性,减少晃动。
一实施例中,割台310的前端设有若干滚轮380,滚轮380与地面相接触。割台组件300通过滚轮380与地面相接触,相较于割台组件300悬空,可以避免移动过程中割台组件300晃动。割台组件300的高度可调节,作为优选,滚轮380在割台310上的位置也可以调节,从而满足在不同切割高度的要求下,滚轮380始终与地面保持接触。
请参阅图38,示例性的,割台310上设置有切割刀322、切割电机321和切割挡板330。切割刀322安装在切割电机321的驱动轴上,切割电机321驱动切割刀322转动进行草地的切割、修理。一实施例中,切割刀322转动的前端为切割刃,转动的后侧设有推草部3223,作为优选,切割刀322转动的后侧边缘进行向下弯折形成推草部3223,由此形成切割刀322前端对草进行切割,后侧推草部3223将切割后的草带离,实现切割后草的定向排放,如切割后的草进行侧排、后排或收集到集草箱内等,以避免切割后的草直接落在原地,避免需要单独进行清理的问题。
请参阅图38,切割挡板330可拆卸固定在割台310上,围成有刀具容纳腔,切割刀322设置在刀具容纳腔内。一实施例中,切割挡板330与割台310通过螺栓可拆卸连接,包括但不限于在切割挡板330上设置有孔的安装板,如与割台310顶板连接的切割挡板330,设有垂直于切割挡板330主体的安装板,安装板与割台310顶板平行,方便切割挡板330与割台310顶板通过螺栓可拆卸连接。不同规格的割台组件300,需要的切割挡板330也不同,对于较大的割台组件300,需要较大的切割挡板330,若切割挡板330为一个整体,既不方便运输,也不方便维保更换。一实施例中,切割挡板330由若干单节切割挡板330组成,不同单节的切割挡板330彼此通过螺栓连接或直接固定在割台310上,相较于整个一体的切割挡板330,单节的切割挡板330加工难度、运输难度均大大降低,更换时也不需要整体更换,仅更换单节的切割挡板330即可,方便运输和维保。
示例性的,割台组件300前进方向的前端切割挡板330底边高于后端切割挡板330底边,即前端切割挡板330的离地高度大于后端切割挡板330的离地高度,前端切割挡板330位于后端切割挡板330的前侧,前端切割挡板330为靠近割草机前轮侧的切割挡板330,后端切割挡板330为靠近割草机后轮侧的切割挡板。在进行割草工作时,割草机按照预定轨迹向前移动,前端切割挡板330首先经过待割草,而后切割刀332对待割草进行切割,而后后端切割挡板330移动经过此区域。前端切割挡板330的底边高于后端切割挡板330的底边,方便草进入到切割区域,避免切割后的碎草由后侧切割挡板330处向后甩出。作为优选,切割刀322的切割高度与前端的切割挡板330平齐或略低于前端的切割挡板330,有效的保证切割后的高度与预期的切割高度相同。

请参阅图5,示例性的,沿割草机11纵向投影,转动区域落入有前轮投影的切割刀322的转动轴线位于对应前轮远离排草311口一侧。即在割草机1纵向方向看,通过切割刀322转动轴将切割刀322转动区域一分为二,前轮位于切割刀322靠近排草口340的转动区域内。具体的,前轮包括第一前轮2101和第二前轮2102,切割刀322包括第一切割刀3221和第二切割刀3222,在正向前进或后退状态时,沿割草机1纵向投影,第一前轮2101的投影与第一切割刀3221转动区域至少部分重叠,第二前轮2102的投影与第二切割刀3222转动区域至少部分重叠。以穿过第一切割刀3221转轴轴线的纵向线为界,将第一切割刀3221切割转动区域分为靠近排草口340和远离排草口340的两个区域,第一前轮2101的投影将落入在靠近排草口340的区域内,即第一切割刀3221的转轴轴线位于第一前轮2101远离排草口340一侧;以穿过第二切割刀3222转轴轴线的纵向线为界,将第二切割刀3222切割转动区域分为靠近排草口340和远离排草口340的两个区域,第二前轮2102的投影将落入在靠近排草口340的区域内,即第二切割刀3222的转轴轴线位于第二前轮2102远离排草340口一侧。换言之,定义一平行于割草机1前进方向,且穿过第一切割刀3221转轴轴线的第一平面,第一前轮2101的投影位于该平面靠近排草340口一侧,在一实施例中,第一前轮2101的投影完全位于该平面靠近排草340口一侧;定义一平行于割草机1前进方向,且穿过第二切割刀3222转轴轴线的第二平面,第二前轮2102的投影位于该平面靠近排草340口一侧,在本实施中,第二前轮2102的投影完全位于该平面靠近排草340口一侧。例如,参见图20,从割草机1底部看,割台310左侧设有排草口340,第一前轮2101的投影落入在靠近排草口340的区域内(第一切割刀3221转轴轴线的左侧),即第一前2101轮位于第一平面左侧;第二前轮2102的投影落入在靠近排草口340的区域内(第二切割刀3222转轴轴线的左侧),即第二前轮2102位于第二平面左侧.割草时,被前轮压倒的草被吸起来,然后切割刀322割掉排出,前轮在这一侧可以使得草直接在靠近排草口340的一侧被割掉,割完直接排出去,另外,气流的风向使得靠近排草口的气流比较大,被前轮碾压的草更容易被吸起来,便于切割。通过前轮和切割刀322的排布提升了排草效果。一实施例中,切割刀322包括还可以包括第三切割刀,第三切割刀可设置于第一切割刀3221和第二切割刀3222之间。在另一实施例中,割草机1还可设置第三前轮、第四切割刀等,本申请对此不做限定。

请参阅图114~图125,在一割草机的实施例中,割草机1包括集草装置,集草装置包括输草装置、集草装置、堵塞检测装置640、满溢检测装置650和卸草装置60。
虽然本申请附图中显示的割草机是一种坐骑式的割草机100,它也可以是任何其它类型或构造设计方案的割草机。进一步地,除了在本说明书中具体描述说明了的各个部件/装置/系统之外,本申请割草机100的其它元部件可以采用任何合适的设计方案,于此不予以具体展开介绍。
在本实施例中,输草装置包括风机620、风机控制器6210和输草管道625。风机控制器6210固定安装在风机620上,风机620分别与割台10和输草管道625相互连通,使得风机620工作时能将由割台10割下来的碎草吸入输草管道625、并继续吹入集草装置内。
本实施例的集草装置采用集草箱630,集草箱630包括两相对设置的第一侧壁631、第二侧壁634、位于第一侧壁631和第二侧壁634之间的前壁633和与前壁相对布置的箱门636,在前壁633和箱门636、以及第一侧壁631和第二侧壁634之间相对地布置有顶壁637和底壁638,可同时参阅图1-2及图8。
如图示116和图118显示,在本实施例中,集草装置设置有与输草装置连通的进草口632,堵塞检测装置640设置在集草装置上靠近草口32的位置。具体地,堵塞检测装置640设置在集草箱630的侧壁上,集草箱630的第一侧壁631上设有进草口632,堵塞检测装置640安装在第一侧壁631靠近进草口632的位置,而满溢检测装置650安装在集草箱630的前壁633上靠近顶壁637的位置。当然,堵塞检测装置640并不局限于安装在第一侧壁631上,堵塞检测装置640还可以安装在输草装置的输草管道625中,堵塞检测装置640可以设置在输草管道625靠近集草装置的一端。
进一步参考图117-118,堵塞检测装置640包括第一传感器646和第一活动件645,当输草装置的输草管道625正常工作时,第一活动件645处于第一状态;当输草装置的输草管道625发生堵塞时,第一活动件645处于第二状态。第一活动件645在输草管道625中的气流作用使其在所述第一状态和第二状态之间切换。当第一活动件645在在气流的作用下位于第一状态时,堵塞检测装置640不发出堵塞信号,当输草管道625发生堵塞时,输草管道625中的气流减小甚至消失,第一活动件645即会处于第二状态,堵塞检测装置640即发出堵塞检测信号。
在本实施例中,当第一活动件645由第一状态转变为第二状态,且第一活动件645维持在第二状态超过预设时长时,堵塞检测装置640生成堵塞信号。优选地,预设时长为3-5秒,预设时长例如可以选择3秒。由于输草管道625中可能会有团草出现,会导致输草管道625中的气流发生变化,从而影响第一活动件645的状态,但是,一定时间后,团草最终进入到集草箱630中,输草管道625中的气流即可回复正常,此种情况下,输草装置并未发生堵塞,因而,本实施例设置预设时长,以避免堵塞检测装置产生错误信号。
堵塞检测装置640进一步包括固定板647,第一传感器646安装在固定板647上,第一活动件645转动连接在集草装置上,第一活动件645相对于集草装置转动,以在第一状态和第二状态之间切换。具体的,固定板647包括一体延伸的第一臂6470和第二臂6471。第一臂6470一端固定在集草箱630的第一侧壁631上,另一端从第一臂6470一体垂直延伸形成第二臂6471,第二臂6471上固定装有第一传感器646。第二臂6471的自由端包括第一限位部6472,用于限制第一活动件第一活动件645的转动以防止第一传感器646被第一活动件645损坏。第一限位部6472可以是自第二臂6471自由端向外延伸的两个凸片,或者其它合适的设计。固定板647的第一臂471可以是焊接固定到集草箱630的第一侧壁631上,或者采用任何其它合适的连接方式固定到第一侧壁631上。本实施例的固定板647为“L”形,当然在其他实施例中,固定板647还可以是其他的形状及结构。
第一活动件645通过螺杆41穿过两个安装柱648、并与垫圈643和螺母644配合,将第一活动件645固定在集草箱630的进草口632的顶端,第一活动件645类似于合页一样可以绕着螺杆41自由转动。其中,安装柱648都为中空设置以供螺杆41从中穿过,并且两个安装柱648之间的间隔距离正好够收容第一活动件645对应的安装部于其间。两个安装柱648采取焊接方式固定在集草箱630的第一侧壁631上,也可以任何其它合适的方式连接到第一侧壁631上。
当输草装置(例如输草管道625)正常工作时,输草装置未发生堵塞,输草管道625中的气流吹动第一活动件645进行转动,第一活动件645在输草管道625中的气流作用下转动到第二状态,并维持在第二状态,此时第一活动件645集草箱630的进草口632的顶端切线方向平齐。当第一传感器646检测到第一活动件645位于第二状态时,第一传感器646不发出堵塞信号。当输草装置(例如输草管道625)发生堵塞时,输草管道625中的气流则会减小,甚至是完全消失,此时气流不足以吹动第一活动件645到达并维持在第二状态,此种情况定义为第一活动件645处于第一状态(本实施例定义处第二状态外的其他状态为第一状态)。当第一传感器646检测到第一活动件645位于第一状态时,第一传感器646发出堵塞(故障)信号。
作为本实施例的优选方案,第一传感器646为开关,第一传感器646通过第一活动件645触发开关的形式检测第一活动件645的状态,第一活动件645触发开关时,第一传感器646检测到第一活动件645处于第一状态,当第一活动件645与开关断开时,第一传感器646检测到第一活动件645处于第二状态。当然,在其他实施例中,第一传感器646还可以是其他类型的传感器,例如位移传感器,位移传感器检测第一活动件645的位移量大小,从而检测第一活动件645的状态。第一活动件645可以通过转动的方式实现状态切换,也可以通过平移等方式实现状态切换。为清楚阐明本申请的方案,本实施例以第一传感器646为开关为例进行阐述。
当输草装置正常工作时候,第一活动件645在来自输草管道625的气流的作用下与第一开关(第一传感器)46闭合,该气流通过进草口632进入集草箱630。当输草装置(例如输草管道625内)发生堵塞时,进入集草箱630的气流会减小直至完全消失,这会使得第一活动件645与第一开关646之间断开闭合,此时,堵塞检测装置640即发出故障信号。进一步地,在本实施例中,当第一活动件645与第一开关646之间当断开的时间超过一定时间间隔(例如3s)时,堵塞检测装置640发出故障信号。
堵塞检测装置640进一步包括固定板647,固定板647包括一体延伸的第一臂6470和第二臂6471。第一臂6470一端固定在集草箱630的第一侧壁631上,另一端从第一臂6470一体垂直延伸形成第二臂6471,第二臂6471上固定装有开关46。第二臂6471的自由端包括限位部6472,用于限制第一活动件645的转动以防止开关46被压片45压坏。限位部6472可以是自第二臂6471自由端向外延伸的两个凸片,或者其它合适的设计。固定板647的第一臂471可以是焊接固定到集草箱630的第一侧壁631上,或者采用任何其它合适的连接方式固定到第一侧壁631上。本实施例的固定板647为“L”形,当然在其它实施例中,固定板647还可以是其他的形状及结构。
进一步地,本申请的堵塞检测装置640配置为检测输草装置中的气流参数,当气流参数小于预设值时,堵塞检测装置640生成堵塞信号。具体地,堵塞检测装置640检测输草装置(例如输草管道625)出口处的风速,风速的预设值可为156M/s,根据实际情况风速的预设值也可以是其它合适的数值。当风速小于预设值超过预设时长(例如3秒)时,堵塞检测装置640发出堵塞信号。
本申请的一较佳实施例中,当从进草口632进入到集草箱630中的风速达到一个预设值时,堵塞检测装置640的第一活动件645会被风推向去触碰第一开关646使之闭合,即由此触发第一开关646。风速的预设值可设为为156M/s,即大于这个风速第一开关646被触发。
当进草口632处的风速为预设值15m/s时,风量为15*15/1600KN/M2,压力为这个值乘以面积,面积可以算1.5e2mm2或者2.5e2mm2。
风压就是垂直于气流方向的平面所受到的风的压力。根据伯努利方程得出的风-压关系,风的动压为:
wp=0.5·ro·v2(1)
其中wp为风压[kN/m2],ro为空气密度[kg/m3],v为风速[m/s]。
由于空气密度(ro)和重度(r)的关系为r=ro·g,因此有ro=r/g。在(1)中使用这一关系,得到
wp=0.5·r·v2/g(2)
此式为标准风压公式。
举例来说,在标准状态下(气压为1013hPa,温度为15℃),空气重度r=0.01225[kN/m3],纬度为45°处的重力加速度g=9.8[m/s2],可得到:wp=v2/1600(3)。
在本申请的一个实施例中,在进草口632没有气流的时候第一活动件645在重力的作用下垂直向下,第一活动件645不触碰开关46,此时第一开关646处于断开状态;当进草口632有一定气流的时候,第一活动件645在气流的作用下(如图4所示)顺指针绕着螺杆41自由转动,转动一定角度(例如90°)后,第一活动件645触碰第一开关646,并被第一开关646的固定板限位,不再继续转动,防止第一开关646被外力压坏,此时开关处于闭合状态,证明此时管道有正常气流通过,管道顺畅。一旦输草管道625内发生堵塞情况,从进草口632流出的气流会减小,当气流减小到一定程度时,则第一活动件645在重力的作用下会逆时针转动向下转动,使得第一开关646断开,断开时间超过预设值(例如3秒)则会发出堵塞信号,割台10停止割草,风机620停止转动,割草机100显示堵塞故障指示,整车停止割草,割草机100从当前工作位置6A(代表检测到输草装置堵塞的位置)自动驾驶到停车检测维修点6P进行 检修(图11)。举例来说,风机620启动,风速可以达到406M/s,压力值可达到1.69kg。当出现堵草的情况,风速会迅速降低至0,没有风压施加给堵塞检测装置640的第一活动件645,由于重力作用,第一活动件645向下转动90度至处于垂直状态,如果没有外力施加压力给第一开关646,则第一开关646断开。
预设时间可设为3秒,断开3秒就是延时3秒钟。由于实际割草会有易导致输草管道625堵塞的团草出现,有时可能处于堵的临界点,时间长一点,有时草团可能就排到集草箱内了而不会最终导致堵塞情况发生。因此就是为了排除这种情况,第一开关646断开的预设时间范围可以设置为3-5秒(或者可以根据实际情况预设为其它合适的时间长度),如此第一开关646断开的时间长了,碎草集仍不能正常进入集草箱630的话,就可以判断是发生堵塞情况了。
上述的第一开关646可以是压力开关、微动开关、行程开关等任何可适用于本申请的堵塞检测装置640的开关或装置。在本实施例中,第一开关646采用的是压力开关。
接下来请参阅图119-120,满溢检测装置650检测集草装置中的草量状态,当草量达到阈值时,满溢检测装置检测到满溢。在本实施例中,草量阈值即为装满集草箱630时的草量。满溢检测装置650安装在所述集草装置(即集草箱630内)内,且靠近集草装置顶部位置。
满溢检测装置650包括至少一个检测单元,多个检测单元设置在集草箱630中的不同位置,当检测单元均检测到集草箱630中的草量达到阈值时,即说明集草箱630中的多个位置处的草量均已达到阈值(草满),此时满溢检测装置650生成满溢信号,即当多个检测单元均检测到集草箱630中的草满时,满溢检测装置650生成满溢信号。
在本实施例中,满溢检测装置650包括第一检测单元6501、第二检测单元6502和第三检测单元6503,三个所述检测单元连接在一个纵向延伸的安装支架658上,安装支架658固定安装在集草箱630的前壁633靠近顶壁637的位置。其中,第一检测单元6501、第二检测单元6502和第三检测单元504各自的位置基本上对应布置在集草箱630前壁633的左边(靠着第二侧壁32)、中间和右边(靠着第一侧壁)位置。
每个检测单元50包括第二传感器656和第二活动件66,第二活动件66具有第一状态和第二状态,当集草箱630内的草量达到阈值(草满)时,集草箱630中的草推动第二活动件66运动到第二状态,此时,第二传感器656检测到第二活动件66位于第二状态。当多个第二活动件66均处于第二状态时,满溢检测装置650即发生满溢信号。
作为本实施例的优选方案,第二传感器656为开关,第二传感器656通过第二活动件66触发开关的形式检测第二传感器656的状态,第二传感器656触发开关时,第二传感器656检测到第二传感器66处于第一状态,当第二活动件66与开关断开时,第二传感器656检测到第二活动件66处于第二状态。当然,在其他实施例中,第二传感器656还可以是其他类型的传感器,例如位移传感器,位移传感器检测第二活动件66的位移量大小,从而检测第二活动件66的状态。第二活动件66可以通过转动的方式实现状态切换,也可以通过平移等方式实现状态切换。为清楚阐明本申请的方案,本实施例以第二传感器656为第二开关为例进行阐述。
每个检测单元501-503包括安装支架部分6580、第二开关656和第二活动件66。每个安装支架部分6580包括一体延伸的第一部分6581、第二部分6582和第三部分6583,第二部分6582延伸在第一部分6581和第三部分6583之间。开关56固定在第三部分6583上,第二活动件655通过长销轴659安装到第一部分6581一端的安装部6584,并且第二活动件655可以绕长销轴659自由转动。
第二开关656可以是压力开关、微动开关、行程开关等任何可适用于本申请的堵塞检测装置640的开关或装置。在本实施例中,第二开关656采用的是压力开关。
值得注意的是,在本申请的某些较佳实施例中,满溢检测装置650可以根据需要包括一个、两个、三个或者更多个检测单元。这些检测单元可以连接到一个共同的安装支架658上,也可以单个地单独地安装在集草箱630的合适位置,例如靠近集草箱630顶壁637的相应位置处。
第二开关656可以是压力开关、微动开关、行程开关等任何可适用于本申请的满溢检测装置650的开关或装置。在本实施例中,第二开关656采用的是压力开关。三个检测单元6501-6503的安装支架部分6580可以是三个检测单元6501-6503各自单独的部分,也可以是三个检测单元501-503的安装支架部分6580共同一体形成一个纵向延伸的安装支架658上。每个安装支架部分6580所包括的第一、第二和第三部分581-583呈“[”形状连续延伸。
第一、第二和第三检测单元6501-6503可以共用一个长销轴659来将各自的第二活动件655安装到各自的安装支架部分6580的第一部分6581上,也可以是各自包括一个销轴来将各自的第二活动件655可转动地安装到各自的安装支架部分6580的第一部分6581上。
满溢检测装置650还可以包括一对开口销653和垫圈52,分别装设在长销轴659的两端上,以防止长销轴659沿安装支架658纵向方向左右窜动。
在本实施例中,第一检测单元6501、第二检测单元6502和第三检测单元504采用串联的方式,即多个第二开关656串联在线路中,当多个第二开关656全部被触发时,即认为集草箱630处于满溢状态。
随着集草箱630内碎草的收集逐渐增多,碎草在自身的重力作用下,会触碰到集草满溢检测装置650内的第二开关656(串联)。正常情况下,来自输草管道625的气流将碎草自集草箱630第一侧壁631上的进草口632吹入集草箱630内之后,碎草最先会在集草箱630靠第二侧壁32的位置开始堆积,然后才会朝靠第一侧壁631的位置慢慢堆积下来。因此,通常情况下,碎草堆会先接触、挤压满溢检测装置650的第一检测单元6501的第二活动件655,使之与对应的开关56闭合。
换言之,当集草箱630内逐渐装满碎草时,是左侧第一检测单元6501的第二活动件655绕长销轴659自由转动一定角度(例如18度,或者其它度数的角度)首先触碰到相应的第二开关656闭合,触碰到安装支架部分6580的第三部分6583被限位,不能继续转动。然后,依次是中间第二检测单元6502的第二开关656闭合,右侧第三检测单元6503的第二开关656最后闭合。当左、中、右三个位置的第二开关656均发生闭合后,满溢检测装置650会发出集草箱满溢信号,割草机100会收到反馈信号,割台10停止割草,风机620停止工作,此时割草机会从当前工作位置6B(代表检测到集草箱630装满的位置)行驶到排草点6M,进行卸草。
本实施例的第一传感器646和第二传感器656可以采用相同的结构,也可以采用不同的结构,第一活动件56和第二活动件66可以采用相同的结构,也可以采用不同的结构,此处不做限定。
如图121-123所示,卸草装置60包括电动推杆663,电动推杆663一端安装在集草箱630的第二侧壁634的框架6340顶部上,电动推杆663的另一端连接到集草箱630的摆臂635的一端。摆臂635的另一端连接到集草箱630的箱门636的框架6360顶部,电动推杆663能推动或拉动摆臂635来带动箱门636打开或关闭。
图122和123中集草箱630和卸草装置60用较粗线条突出显示,而割草机100及它的其它部件皆以较细(浅)线条示意。图10中示意箱门636旋转30度左右可以从打开位置转动至关闭位置,反之亦然。箱门636在打开和关闭位置之间需要旋转的度数可以根据实际情况来设定。
本申请的一个实施例中,底壁638不与顶壁637平行,而是相对顶壁637 向下倾斜一定角度(可以是任何合适的角度),从而使得进入集草箱630的碎草在箱门636打开时在重力作用下能很容易地从集草箱630内倾倒出来,有利于快速、彻底地完成卸草过程。
电动推杆663后端通过螺栓661和螺母662安装在集草箱630第二侧壁634的框架6340上,另外一端通过螺栓664和螺母665固定在集草箱门636的摆臂635上。正常状态下集草箱门636通过电动推杆663的作用牢固地闭合。当集草箱630内草满后,当割草机100自动行驶到达排草点6M(图11)后,集草箱630上电动推杆663会收到工作信号,推开集草箱630的箱门636,箱门636打开后,碎草会在重力作用下自动滑落。经过设定的卸草时间间隔,电动推杆64会自动收回,集草箱630箱门636关闭,自动卸草过程完成。割草机100自动行驶到割台10上一次割草停止的位置6B,继续割草。
本申请的堵塞检测装置640、满溢检测装置650和卸草装置60的各元、部件可以采用任何能够帮助实现其预定功能的材料制作。例如,第一活动件645和/或第二活动件655可以使用耐磨、强度高材质的弹簧钢,而其他元部件的材质可以使用普通的Q235钢。
再参阅图124和125,本申请割草机100包括集草系统控制装置6105,可接收来自满溢检测装置650的满溢信号和堵塞检测装置640的堵塞信号,并根据接收到的信号控制割草装置、输草系统、集草装置和卸草装置60相互配合工作。
割草机100进一步包括自动驾驶控制系统6106。集草系统控制装置6105将输草装置的故障情况和集草装置的负荷情况分别发送到自动驾驶控制系统6106。
集草系统控制装置6105可以安装在割草机100座椅下方,集草风机控制器6210装在风机620上用于控制风机620的工作状况,自动驾驶控制系统6106可以安装在座椅后面的平板下。集草系统控制装置6105和自动驾驶控制系统6106也可以布置在割草机100的其它合适的部位位置。
堵塞检测装置640、满溢检测装置650和自动卸草装置660分别通过电线电性连接到集草系统控制装置6105,具体布线方式可以采用任何合适的方式,在本说明书不作详述。集草系统控制装置6105可以同时是割草机100本身的中央控制器,分别控制堵塞检测装置640、满溢检测装置650和自动卸草装置660。集草系统控制装置6105也可以同时具有控制割草机100其它元部件的功能。
当输草装置(例如输草管道625)发生堵塞故障时,自集草箱630的进草口632进入集草箱630的气流将会减少至使得堵塞检测装置640的第一活动件645在重力作用下断开与第一开关646的闭合,堵塞检测装置640向集草系统控制装置6105发送故障信号,集草系统控制装置6105通知自动驾驶控制系统6106,自动驾驶控制系统6106控制并操纵割草机100从当前工作位置6A(记录为断点位置6A)行驶到故障修理区6P进行相应修理。当经过修理消除了故障后,集草系统控制装置6105根据收到的信号(例如可以是检修人员向集草系统控制装置6105输入的信号,或者以其它可能的方式向集草系统控制装置6105发出的相应信号)通知自动驾驶控制系统6106,自动驾驶控制系统6106将控制割草机100从故障修理区6P行驶回到断点位置6A继续割草作业。也可以是检修人员直接向自动驾驶控制系统6106发出信号通知控制割草机100返回断点位置6A。
当在进入集草箱630的碎草堆积逐渐堆满时产生的压力作用下满溢检测装置650的第一、第二和第三检测单元501-503的第二活动件655和第二开关656都闭合时,满溢检测装置650将发送满溢信号到集草系统控制装置6105,集草系统控制装置6105将通知自动驾驶控制系统6106,自动驾驶控制系统6106将控制操纵割草机100从当前工作位置6B(记录为断点位置6B)行驶到排草区域6M,然后通知集草系统控制装置6105,由集草系统控制装置6105控制卸草装置60的电动推杆663推动集草箱630箱门636的摆臂635打开集草箱630的箱门636进行卸草,经过预定时间间隔后电动推杆663将带动摆臂635关上箱门636,完成卸草。当卸草工作结束后,集草系统控制装置6105根据收到的信号(例如可以是电动推杆663自动发出的信号,也可以是特定人员向集草系统控制装置6105输入的信号,或者其它可能的方式发出的相应信号)通知自动驾驶控制系统6106,自动驾驶控制系统6106控制割草机100从卸草区域6M行驶回到断点位置6B继续割草作业。也可以是特定人员直接向自动驾驶控制系统6106发出信号通知控制割草机100返回断点位置6B。
卸草过程中,电动推杆35一旦开始工作,碎草就开始往外泄漏;到箱门636打开的最大状态时,碎草基本已经倾倒完成。预定时间间隔是根据电动推杆35的速度来进行设定的,例如可以设为15秒,再预留5秒的公差,可推荐预定时间间隔是15-20秒。
综上所述,本申请的割草机及其集草系统,在割草机(割草机)自动驾驶的模式下实现如下功能:堵塞自动检测、自动集草满溢检测和自动卸草三大功能,可以配合无人驾驶状态下割草机工作,也可以应用于有驾驶员操纵的割草机。所以,本申请有效克服了现有技术中的种种缺点而具高度产业利用价值。

可参图111及112,当割草机1测绘以标定草坪5的地图时,割草机1沿待标定草坪185的割草区域(即工作区域)1852的边界1850行驶,GNSS定位移动站(定位装置)14实时采集割草机1的定位坐标。控制器240实时监控割草机1是否处于高精度定位状态,如果不在高精度定位状态则反馈定位系统异常到手持终端1830;如果一直处于高精度定位状态则持续记录割草机1的定位坐标,直至手持终端1830发送地图边界标定完成指令给割草机1的控制器240。由于定位装置14装设在割草机1上,所以可认为控制器240其实是在实时监控定位系统是否处于高精度定位状态。控制器240根据从开始标定到结束标定指令之间收到的割草机1的定位坐标生成割草区域1852的标定地图,并将标定地图储存到储存装置,同时对应储存RTK基站3发出的RTK基站坐标。
当完成标定割草区域1852的地图后,手持终端1830可进一步向述割草机1发送不可割草区域标定指令,不可割草区域即障碍物1855、1856等。割草机1沿不可割草区域(障碍物)1855或1856的边界行驶,GNSS定位移动站14实时采集割草机1的定位坐标,控制器240实时监控割草机1(或者定位系统)是否处于高精度定位状态。如果不在高精度定位状态则反馈定位系统异常到手持终端1830;如果一直处于高精度定位状态则持续记录割草机1的定位坐标,直至手持终端1830向割草机1发送不可割草区域标定完成指令。控制器240根据从开始标定到结束标定指令之间收到的割草机1的定位坐标生成不可割草区域(障碍物,亦为非工作区域)1855或1856的标定地图,并与割草区域1852的标定地图比较校验不可割草区域1855、1856的边界是否超出割草区域(待标定地块)1852的边界1850(或者说校验不可割草区域1855、1856的边界是否与割草区域(待标定地块)1852的边界1850181850冲突),同时对应储存不可割草区域1855、1856的边界标定地图和RTK基站1820发出的RTK基站坐标。
割草区域1852的标定地图以及不可割草区域1855或1856的标定地图可以储存在控制器240、手持终端1830、或者可与割草机及手持终端1830通信的服务器1840上。
本申请中,当对割草区域1852的标定地图进行相应偏移时,标定地图先由储存装置调用、并发送给控制器240的地图生成及管理模块,地图生成及管理模块计算标定地图中的RTK基站坐标与当前RTK基站1820的RTK基站坐标的差值,然后将标定地图内的所有点的坐标加上计算出的差值,从而生成偏移后的新地图,割草机1即可根据这个新地图来进行割草作业。
进一步地,本申请提供一种用于割草机1的地图标定及调用方法,包括:
步骤一为地图标定及生成流程/步骤,可同时参阅图111。开始地图标定,割草机1沿待标定的割草区域1852的边界1850行驶,GNSS定位移动站14实时采集(监测并记录)割草机1的定位坐标。GNSS定位移动站14应用来自RTK基站1820的差分数据修正割草机1的定位坐标数据,并将修正的定位坐标数据发送给割草机1的控制器240,控制器240应用修正的定位坐标数据和来自RTK基站1820的基站坐标数据生成割草区域1852的标定地图,并将标定地图发送给相应的储存装置进行储存。
控制器240实时监测割草机1是否处于高精度定位状态的信息。如果不在高精度定位状态,则反馈定位系统异常到用于手持终端1830;如果一直处于高精度定位状态,则持续记录割草机1的定位坐标,直至手持终端1830发送地图边界标定完成指令,控制器240根据从开始标定到结束标定指令之间收到的割草机1的定位坐标生成并储存割草区域1852的标定地图,同时对应储存RTK基站1820发出的RTK基站坐标。
当完成上述标定地图后,手持终端1830可进一步向割草机1发送不可割草区域标定指令。割草机1沿不可割草区域(例如障碍物1855或1856)的边界行驶,控制器1的地图生成管理模块实时监控GNSS移动站1815/割草机1(或者说监控定位系统)是否处于高精度定位状态。如果不在高精度定位状态,则反馈定位系统异常到手持终端1830;如果一直处于所述高精度定位状态,则持续记录割草机1的定位坐标,直至手持终端1830向割草机1发送不可割草区域标定完成指令。控制器240根据从开始标定到结束标定指令之间收到的割草机1的定位坐标生成不可割草区域1855或1856的标定地图,并校验不可割草区域1855或1856是否与割草区域边界1850冲突(即是否超出割草区域边界1850),同时对应储存RTK基站1820发出的RTK基站坐标。
步骤一进一步包括将不可割草区域1855或1856的标定地图与割草区域1852的标定地图进行比较,以校验不可割草区域1855或1856是否在割草区域1852的边界内。
图111所示的实施例中,本申请地图标定和生成的流程包括:
(1)开始地图标定;
(2)割草机1沿割草区域1852的边界1850行驶,地图生成系统(例如控制器240的地图生成及管理模块)通过GNSS定位移动站14采集割草机1的定位坐标;
(3)控制器240根据GNSS定位移动站14提供的状态信息来判断定位系统(GNSS定位移动站14和割草机1)是否处于高精度定位状态,如果是,则继续判断割草机1是否完成绕边界1850的行驶,如果为否,则发出定位系统状态异常的警报;
(4)如果控制器240判断割草机1已完成绕边界1850的行驶,则手持终端发出指令储存割草机1轨迹坐标生成标定地图,并储存RTK基站坐标;如果控制器240判断割草机1未完成绕边界1850的行驶,则继续回到步骤(3);
(5)储存割草机1轨迹坐标生成标定地图、并储存RTK基站坐标之后,控制器240判断是否需要增加标定不可割草区域(例如障碍物1855和1856),如果判断需要则手持终端1830发出标定不可割草区域的指令,如果判断不需要则流程结束(完成);
(6)手持终端1830发出标定不可割草区域的指令后,控制器240根据控制器240监测的状态信息来判断定位系统是否处于高精度定位状态,如果是,则继续判断割草机1是否完成绕不可割草区域边界的行驶,如果为否,则发出定位系统状态异常的警报;
(7)如果控制器240判断割草机1已完成绕不可割草区域边界的行驶,控制器240继续校验不可割草区域是否与割草区域边界1850冲突(通常是指不可割草区域已经超出了割草区域1852的边界1850)。如果是,则回到步骤(6);如果否,则储存不可割草区域到步骤(4)的标定地图中,然后回到步骤(5);
(8)如果控制器240判断割草机1未完成绕不可割草区域边界的行驶,则回到步骤(6)。
本申请用于割草机1的地图标定及调用方法的步骤二为标定地图的调用流程。当割草机1对割草区域1852进行割草作业时,控制器240从储存装置调用储存的标定地图。在地图调用时需要割草机1的控制器240计算出本次RTK基站1820的定位(位置)坐标与标定地图中对应的RTK基站位置坐标的偏差(即差值),并且根据两次RTK基站偏差值(差值)相应地偏移草坪185的标定地图。
并且根据GNSS单点定位精度标准差设置RTK基站偏差范围预设值,当偏差超过预设值时提醒操作员基站位置异常,检查RTK基站是否放在了固定锚点上。
图112的实施例中包括以下步骤:
(1)开始调用草坪185的标定地图;
(2)由储存有标定地图的储存装置来选择用于割草作业的标定地图;
(3)控制器240判断标定地图中RTK基站位置与当前RTK基站1820的RTK基站定位(位置)偏差是否小于预设值,如果是则进入下一步骤,如果否,则向手持终端1830或者服务器1840报告基站位置异常;
(4)控制器240根据标定地图RTK基站定位坐标与当前RTK基站1820的RTK基站定位坐标之间的偏差来偏移标定地图,生成新地图用于割草作业;
(5)流程结束(完成)。
本申请方法的步骤三是对标定地图进行偏移的流程。控制器240将标定地图中的RTK基站坐标和当前RTK基站1820的RTK基站坐标进行比较。如果比较所得的偏差值小于预设值(例如1.5m),则对标定地图进行相应偏移,并生成新的地图供割草作业使用;如果比较所得的偏差值大于预设值(例如1.5m),则报警RTK基站1820位置异常。
步骤三中,所述储存装置调用、并将所述标定地图发送给所控制装置,所述控制装置计算所述标定地图中的RTK基站坐标与当前所述RTK基站的RTK基站坐标的差值,然后将所述标定地图内的所有点的坐标加上计算出的所述差值,从而生成偏移后的新地图,所述割草机即可根据所述新地图来进行割草作业。
以下就本申请的标定地图偏移方法举例说明:
绘制标定地图时RTK基站1位置的经纬度坐标为(X0,Y0),
标定地图的边界为{(MX1,MY1),(MX2,MY2),···,(MXn,MYn)},
障碍物(不可割草区域)1边界为{(1OX1,1OY1),(1OX2,1OY2),···,(1OXn,1OYn)},
障碍物(不可割草区域)2边界为{(2OX1,2OY1),(2OX2,2OY2),···,(2OXn,2OYn)},
·····
障碍物(不可割草区域)m边界为{(m2OX1,mOY1),(mOX2,mOY2),···,(mOXn,mOYn)}。
下一次割草时,RTK基站坐标为(X1,Y1),则需要偏移的偏移量(差值)为(detaX,detaY)=((X1-X0),(Y1-Y0)),
割草时经过偏移后生成的新地图的边界为{((MX1-detaX),(MY1-detaY)),((MX2-detaX),(MY2-detaY)),···,((MXn-detaX),(MYn-detaY))},
新地图的障碍物1边界为{((1OX1-detaX),(1OY1-detaY)),((1OX2-detaX),(1OY2-detaY)),···,((1OXn-detaX),(1OYn-detaY))},
新地图的障碍物2边界为{((2OX1-detaX),(2OY1-detaY)),((2OX2-detaX),(2OY2-detaY)),···,((2OXn-detaX),(2OYn-detaY))},·
····
新地图的障碍物m边界为{((mOX1-detaX),(mOY1-detaY)),((mOX2-detaX),(mOY2-detaY)),···,((mOXn-detaX),(mOYn-detaY))}。
同理,一种具有高程(海拔)信息的地图偏移方法举例:
绘制标定地图时RTK基站1820位置的经纬度和海拔坐标为(X0,Y0,H0),
标定地图的边界为{(MX1,MY1,MH1),(MX2,MY2,MH2),···,(MXn,MYn,MHn)},
障碍物(不可割草区域)1边界为{(1OX1,1OY1,1OH1),(1OX2,1OY2,1OH2),···,(1OXn,1OYn,1OHn)},
障碍物(不可割草区域)2边界为{(2OX1,2OY1,2OH1),(2OX2,2OY2,2OH2),···,(2OXn,2OYn,2OHn)},·
····
障碍物(不可割草区域)m边界为{(m2OX1,mOY1,mOH1),(mOX2,mOY2mOH2),···,(mOXn,mOYn mOHn)},····
下次割草时,RTK基站坐标为(X1,Y1,H1),则需要偏移的偏移量(差值)为(detaX,detaY,detaH)=((X1-X0),(Y1-Y0),(H1-H0)),
割草时经过偏移后生成的新地图的边界为{((MX1-detaX),(MY1-detaY),(MH1-detaH)),((MX2-detaX),(MY2-detaY),(MH2-detaH)),···,((MXn-detaX),(MYn-detaY),(MHn-detaH))},
新地图的障碍物1边界为{((1OX1-detaX),(1OY1-detaY),(1OH1-detaH)),((1OX2-detaX),(1OY2-detaY),(1OH2-detaH)),···,((1OXn-detaX),(1OYn-detaY),(1OHn-detaH))},
新地图的障碍物2边界为{((2OX1-detaX),(2OY1-detaY),(2OH1-detaH)),((2OX2-detaX),(2OY2-detaY),(2OH2-detaH)),···,((2OXn-detaX),(2OYn-detaY),(2OHn-detaH))},
····
新地图的障碍物m边界为{((mOX1-detaX),(mOY1-detaY),(mOH1-detaH)),((mOX2-detaX),(mOY2-detaY),(mOH2-detaH)),···,((mOXn-detaX),(mOYn-detaY),(mOHn-detaH))}。
综上,本申请可提供一种作业设备(例如割草机1)系统的控制方法,包括以下步骤:

其中,调用标定地图时,
获取当前RTK基站坐标;
比较原始RTK基站坐标和当前RTK基站坐标,如果比较所得的偏差值小于预设值则对标定地图进行相应偏移、并生成新地图供作业使用,如果比较所得的偏差值大于预设值则报警RTK基站位置异常。
在本申请的又一实施例中,本申请可进一步提供一种作业设备系统,其不仅可以用于割草机1,还可以用于需要对某一地块进行地图标定、以及后续需要调用所标定的地图(例如用于导航)的其它作业设备或场合。本申请的作业设备系统包括RTK基站1820和作业设备1,作业设备例如可以是割草机1。作业设备包括与RTK基站1820通信的控制器240、定位装置14和储存装置。定位装置14实时采集地图标定及调用系统1的定位坐标。当地图标定及调用系统1对待标定地块185进行地图标定时,定位装置14应用来自RTK基站1820的差分数据修正该地图标定及调用系统的定位坐标数据、并将修正的定位坐标数据发送给控制器240。控制器240应用所述修正的定位坐标数据和来自所述RTK基站1820的基站坐标数据生成待标定地块185的标定地图,并将该标定地图发送给储存装置进行储存。当地图标定及调用系统对待标定地块(即工作区域,或称待割草区域)185进行导航、或者需要使用该待标定地块185的已经完成的标定地图时,控制器240将标定地图中的RTK基站坐标和当前RTK基站1820的RTK基站坐标进行比较。如果比较所得的偏差值小于预设值则对该标定地图进行相应偏移、并生成新地图以用于导航等使用用途;如果比较所得的所述偏差值大于所述预设值,则报警所述RTK基站位置异常。
RTK基站1820为便携式RTK基站1820,可布置在所述待标定地块185附近的固定锚点20。
控制器240和定位装置14通过通讯装置1818与RTK基站1820进行通信。通讯装置1818接收来自RTK基站1820的差分数据和RTK基站坐标数据,并将差分数据发送给定位装置14、以及将RTK基站坐标数据发送给控制器240。
通讯装置1818包括安装在该地图标定及调用系统上的电台装置,而定位装置14可以是卫星定位移动站。
本申请地图标定及调用系统进一步包括终端控制装置3,其可以接收地图标定及调用系统反馈的状态信息,并发送相应的控制指令给该系统。状态信息包括该地图标定及调用系统的定位状态信息和报警信息。定位状态信息包括高精度定位状态信息和非高精度定位状态信息。高精度定位状态信息指示该地图标定及调用系统处于厘米级定位状态。报警信息是指地图标定及调用系统的故障状态信息。
当终端控制装置3接收到的定位状态信息为所述高精度定位状态信息时,终端控制装置3发送相应的执行指令给地图标定及调用系统1,执行指令可包括继续当前状态的指令和标定地图的指令。
当终端控制装置3接收到的定位状态信息为非高精度定位状态信息时,终端控制装置3发送停机指令给地图标定及调用系统1。当终端控制装置3接收到报警信息时,终端控制装置3显示该报警信息,通知操作员,由操作员通过终端控制装置3发送相应的处理指令给该系统。
在本申请的一个较佳实施例中,通讯装置1818还包括用于与终端控制装置3进行无线通信的蓝牙装置17和4G-GPS模块1816。4G-GPS模块1816可以将控制器240的信息上传到服务器1840,然后服务器1840可以将控制器240的信息发送到终端控制装置3,并且终端控制装置3的指令也可以通过移动网络发送到服务器1840、再进一步发送到控制器240。
当地图标定及调用系统1测绘待标定地块5的定标地图时,该系统沿待标定地块185的边界1850行驶,定位装置14实时采集该系统的定位坐标。控制器240实时监控该系统1是否处于高精度定位状态,如果不在高精度定位状态则反馈定位系统异常到终端控制装置3,如果一直处于高精度定位状态则持续记录该系统的定位坐标,直至终端控制装置3发送地图边界标定完成指令。控制器240根据从开始标定到结束标定指令之间收到的该系统的定位坐标生成待标定地块185的标定地图,并将标定地图储存到储存装置,同时对应储存RTK基站1820发出的RTK基站坐标。
当完成待标定地块185的标定地图后,终端控制装置3可进一步向该系统发送障碍物标定指令。该系统沿所述障碍物(即非工作区域,或称不可割草区域)1855、1856边界行驶,定位装置14实时采集该系统1的定位坐标。控制器240实时监控该系统是否处于高精度定位状态,如果不在高精度定位状态则反馈定位系统异常到终端控制装置3;如果一直处于高精度定位状态则持续记录该系统的定位坐标,直至终端控制装置3向该系统发送障碍物标定完成指令。控制器240接着将障碍物1855、1856的标定地图与待标定地块185的标定地图进行比较,以校验障碍物1855、1856是否在待标定地块185的边界1850内。然后,根据从开始标定到结束标定指令之间收到的该系统的定位坐标生成并储存障碍物1855、1856的标定地图,同时对应储存RTK基站1820发出的RTK基站坐标。
当对待标定地块185的标定地图进行相应偏移时,标定地图先被储存装置调用、并发送给控制器240。控制器240计算标定地图中的RTK基站坐标与当前RTK基站1820的RTK基站坐标的差值,然后将标定地图内的所有点的坐标加上计算出的差值,从而生成偏移后的新地图,该系统即可根据新地图来进行导航或用于其它用途。
如图7所示,在本申请的一个实施例中,当无人驾驶割草机1对待割草草坪185进行割草作业时,GNSS定位移动站(定位装置)14实时采集割草机1的定位坐标,由无人驾驶控制器240通过通讯装置(模块)18将所存RTK基站坐标发送到RTK基站1820,或者手持终端1830通过蓝牙或wifi等无线通讯方式将所存RTK基站坐标基站发送到RTK基站1820,RTK基站1820对比当前坐标与接收到的坐标,如果比较所得的偏差值小于预设值则将接收到的坐标设置为RTK基站坐标,如果比较所得的偏差值大于预设值则报警RTK基站位置异常。
综上所述,本申请提供应用RTK基站的割草机、以及用于该割草机的地图标定及调用方法与系统,通过偏移割草草坪的地图来解决RTK基站每次重新定位时的位置漂移问题,在生成并储存草坪的标定地图(包括RTK基站的基站坐标),在下一次割草时割草机会自动调用和偏移该标定地图用于后续的割草作业,因此在发生草坪地图偏差情况时无需人工输入新的坐标,从而实现了割草作业的自动化,大大提高了工作效率。
进一步地,本申请提供如前所描述的作业设备系统及其控制方法,除了可以用于割草机标定和调用地图之外,还可以用在需要对某一地块进行地图标定、以及后续需要调用所标定的地图(例如用于导航)的其它作业设备或情形。
所以,本申请有效克服了现有技术中的一些实际问题从而有很高的利用价值和使用意义。上述实施例仅例示性说明本申请的原理及其功效,而非用于限制本申请。任何熟悉此技术的人士皆可在不违背本申请的精神及范畴下,对上述实施例进行修饰或改变。因此,举凡所属技术领域中具有通常知识者在未脱离本申请所揭示的精神与技术思想下所完成的一切等效修饰或改变,仍应由本申请的权利要求所涵盖。
