具体实施方式
一边适宜地参照附图一边对本发明的实施方式详细地进行说明。
此外，在各实施方式的说明中，对相同的结构要素标注相同的附图标记，并省略重复的说明。
[第1实施方式]
如图1所示，第1实施方式的割草机1A是用于切割地面上的草的手推式作业机。割草机1A具有主体部10、把手20和集草容器50，其中，所述主体部10能向前方移动；所述把手20被设置于主体部10的后部；所述集草容器50与主体部10的后部连接，主体部10内与集草容器50内经由排草通路13连通。
主体部10具有：箱形的外壳11；前后左右四个车轮15，其被设置于外壳11；割草刀片16，其被设置于外壳11内；和驱动马达17，其被设置于外壳11的上表面。
此外，在第1实施方式的割草机1A中，以马达作为驱动源，但驱动源并没有限定，例如也可以将发动机作为驱动源。
在外壳11内形成有圆筒状的收容部12，该收容部12绕上下方向的轴形成有周壁部(参照图2)。收容部12的下端部在外壳11的底部(下表面)开口。
在收容部12的下部收容有割草刀片16(参照图2)。第1实施方式的割草刀片16为沿收容部12的径向延伸的直线状的切割刀片。割草刀片16能绕上下方向的轴旋转。此外，割草刀片16的结构并没有限定，可以使用圆盘状的割草刀片、十字形状的割草刀片等各种割草刀片。
驱动马达17是使设置于外壳11内的割草刀片16和风扇(未图示)旋转的驱动源。
割草刀片16通过驱动马达17在收容部12内旋转。另外，通过驱动马达17使风扇旋转，由此割草刀片16割取的草从外壳11被向后方排出。
把手20为从主体部10的后部向后方朝斜上方延伸的U形的棒状部件。把手20的两端部与主体部10的后部连接。通过作业者推动把手20，能使割草机1A移动。
把手20能向主体部10的顶部(上部)侧折回，从而与主体部10的顶部重叠(参照图2)。
此外，把手20的结构并不限定于U形，可以应用T形、L形等各种形状，只要为能向主体部10的顶部侧折回而与顶部重叠的形状即可。
在作业时的割草机1A中，集草容器50是被配置在主体部10的后方的大致长方体的容器。集草容器50具有框架51和覆盖框架51的罩55。
框架51具有：上框部52，其构成集草容器50的上表面的外缘；前框部53，其构成集草容器50的前表面的外缘；和左右的连接用挂钩54、54，其被设置于前框部53。
左右的连接用挂钩54、54分别被设置于前框部53的左右的缘部，且向前方突出。连接用挂钩54的前部向下方弯屈。
罩55是覆盖在框架51上的由布制成的大致长方体的袋体。罩55的上部被支承于框架51的上框部52，罩55的前部被框架51的前框部53支承。罩55的前部开口。
罩55的左右的侧部、底部和后部没有被框架51支承，而被悬吊于框架51的上框部52。另外，左右的连接用挂钩54、54从罩55向前方突出。
通过将集草容器50配置于图1所示的主体部10的后方，且使左右的连接用挂钩54、54勾挂于主体部10的后端部，能够将集草容器50连接在主体部10的后部。
通过一边使割草刀片16旋转一边由作业者推动把手20使割草机1A向前方移动，割草机1A能够利用割草刀片16来切割地面上的草。另外，由割草刀片16割取的草从主体部10向后方排出而被收容在集草容器50内。
在保管割草机1A的情况下，从主体部10拆下集草容器50。另外，将把手20向主体部10的顶部侧(前侧)折回，使把手20与主体部10的顶部重叠。
接着，如图2所示，以主体部10的后部为下侧，主体部10的前部为上侧的方式使主体部10立起。据此，主体部10的底部成为向侧方露出的状态。
从主体部10上拆下的集草容器50以前部为下侧且后部为上侧的方式进行配置。并且，使集草容器50的底部与立起的主体部10的底部相对。
然后，如图3所示，使集草容器50的底部进入主体部10的收容部12内，将集草容器50的框架51的前框部53载置于收容部12的内表面的下部。此外，两连接用挂钩54、54被配置在收容部12的外侧。
据此，集草容器50的一部分成为被嵌入到主体部10的收容部12内的状态，集草容器50的下部被设置于主体部10的收容部12的内表面的两个支承部14、14支承。
第1实施方式的支承部14是收容部12的内表面的一部分。两支承部14、14隔着割草刀片16被配置在割草刀片16的左右两侧。此外，在第1实施方式中，两支承部14、14为相同的结构(弯曲形状)，但也可以使两支承部14、14构成为彼此不同的结构。
如图3所示，在上面那样的割草机1A中，能够从主体部10拆下集草容器50，使主体部10立起，并且将集草容器50安装于主体部10的底部。
此时，由于集草容器50的一部分进入到主体部10的收容部12内，集草容器50被支承于收容部12的内表面，因此能使集草容器50相对于主体部10稳定。
在第1实施方式的割草机1A中，由于集草容器50的下端部的两点被隔着割草刀片16配置在收容部12的下端部的两个支承部14、14支承，因此，与由一点支承集草容器50的情况相比，能够提高稳定性。据此，即使在收纳时割草机1A摇晃，由于集草容器50不容易相对于收容部12偏移，因此割草刀片16不易露出到外部。
另外，通过使集草容器50的一部分进入到主体部10的收容部12内，可以将主体部10和集草容器50紧凑地连接，因此可以减小收纳空间。
并且，通过使集草容器50与主体部10的底部重叠，并使集草容器50的一部分进入到收容部12内，能够利用集草容器50覆盖割草刀片16。据此，能够抑制保管割草机1A时割草刀片16向外部露出。
此外，在图3中，为了明确集草容器50的框架51和主体部10的安装状态，用假想线来表示罩55。因此，在图3中，虽然 从外部能看见割草刀片16，但实际上割草刀片16被框架51和罩55覆盖。
如此，能够将集草容器50稳定地安装在割草机1A的立起的主体部10的底部，从而能安全且紧凑地进行保管。
上面，对本发明的第1实施方式进行了说明，但本发明并不限定于所述第1实施方式，在不脱离其主旨的范围内能适宜地变更。
在图1所示的割草机1A中，主体部10及集草容器50的形状没有限定。另外，割草刀片16及驱动马达17的形状也没有限定。
如图3所示，第1实施方式的割草机1A构成为集草容器50的一部分进入到主体部10的收容部12内，但也可以构成为集草容器50整体进入到收容部12内。
另外，也可以为：在主体部10的收容部12的内表面，在与集草容器50的外表面接触的支承部14上粘贴橡胶板等弹性部件。
另外，也可以为：在集草容器50的罩55的外表面，在与收容部12的内表面的支承部14接触的部位粘贴橡胶板等弹性部件，或者提高该部位的摩擦系数。
通过采用这些结构，能提高安装于立起的主体部10上的集草容器50的稳定性。
[第2实施方式]
接着，一边适宜地参照附图一边对本发明的第2实施方式详细地进行说明。如图4所示，第2实施方式的割草机1B是与所述第1实施方式的割草机1A(参照图2)大致相同的结构，在集草容器50上设置有卡合部61这一点不同。
卡合部61是被设置于集草容器50的框架51的前框部53上的挂钩。在第2实施方式中，在前框部53上设置有左右两个卡合部61、61。
当保管第2实施方式的割草机1B时，使主体部10立起，将集草容器50安装到主体部10的底部。此时，通过前框部53和两个卡合部61、61夹住主体部10的收容部12的周壁部，由此集草容器50的下部被固定于主体部10，因此可以使集草容器50相对于主体部10稳定。
上面对本发明的第2实施方式进行了说明，但本发明不限定于所述第2实施方式，与所述第1实施方式相同，在不脱离其主旨的范围内能适宜地变更。
例如，卡合部61的数量、配置并没有限定，可以根据集草容器50和主体部10的大小、形状来适宜地设定。
[第3实施方式]
接着，一边适宜地参照附图一边对本发明的第3实施方式详细地进行说明。如图5所示，第3实施方式的割草机1C是与所述第1实施方式的割草机1A(参照图2)大致相同的结构，在主体部10上设置有嵌合部62这一点不同。
第3实施方式的嵌合部62是形成于外壳11的内表面的槽状的台阶部。在第3实施方式中，在外壳11的前端部的内表面形成有左右两个嵌合部62、62，在收容部12的内表面的左右支承部14、14上形成有左右两个嵌合部62、62。嵌合部62从底部侧的开口缘部向顶部侧呈直线状延伸。
各嵌合部62形成为：在使主体部10立起时被配置在外壳11的内表面的上下左右四个部位。
另外，在第3实施方式的集草容器50的框架51上设置有构成后部的外缘的后框部56。
当保管第3实施方式的割草机1C时，使主体部10立起，将集草容器50安装于主体部10的底部。此时，将集草容器50的前框部53的左右缘部插入到外壳11的下侧的左右嵌合部62、62中，并且将后框部56的左右缘部插入到外壳11的上侧的左右嵌合部62、62中。
据此，集草容器50的上部和下部与主体部10的外壳11彼此嵌合，因此可以使集草容器50相对于主体部10稳定。
上面对本发明的第3实施方式进行了说明，但本发明并不限定于所述第3实施方式，与所述第1实施方式相同，在不脱离其主旨的范围内能适宜地变更。
例如，嵌合部62的数量、配置没有限定，可以根据集草容器50和主体部10的大小、形状来适宜地设定。
[第4实施方式]
接着，一边适宜地参照附图一边对本发明的第4实施方式详细地进行说明。如图7所示，第4实施方式的割草机1D是与所述第1实施方式的割草机1A(参照图2)大致相同的结构，在主体部10上设置有连接部63这一点不同。
如图6所示，连接部63被设置在主体部10的前端部。连接部63是弯折成U字形状的棒状部件。连接部63的两端部与主体部10的前端部连接，并向前方突出。连接部63起到缓冲器(bumper)的作用，该缓冲器用于在使主体部10向前方移动时防止障碍物碰到主体部10。另外，连接部63的两端部与主体部10的前端部的左右侧面连接，以该连接部为旋转中心，连接部63可向主体部10的底部侧自如倾摆。
当保管第4实施方式的割草机1D时，使主体部10立起，将集草容器50安装到主体部10的底部。然后，如图7所示，将连接部63向主体部10的底部侧放倒，使连接部63勾挂在集草容器50的上部。
这样一来，除了基于集草容器50与主体部10的收容部12的内表面相抵接来固定之外，还可以通过被设置在主体部10的上部的连接部63将集草容器50的上部连接于主体部10，由此使集草容器50相对于主体部10更加稳定。
另外，集草容器50通过连接部63被固定在主体部10的上部，并通过与收容部12的内表面抵接而被固定在主体部10的下 部。这样，上下的固定部隔着割草刀片16而配置。通过该结构，集草容器50在上下左右的任意方向上都被稳定地固定于主体部10，因此能防止集草容器50相对于主体部10偏移，能有效地防止割草刀片16露出到外部。
另外，由于被设置在主体部10的上部的连接部63包围并保持集草容器50的上部，因此即使在主体部10向多个方向摇晃或倾斜的情况下，也能防止集草容器50相对于主体部10偏移或脱落。
上面对本发明的第4实施方式进行了说明，但本发明并不限定于所述第4实施方式，与所述第1实施方式相同，在不脱离其主旨的范围内能适宜地变更。
例如，连接部63的形状没有限定，可以根据集草容器50和主体部10的大小、形状来适宜地设定。
[第5实施方式]
接着，一边适宜地参照附图一边对本发明的第5实施方式详细地进行说明。如图8所示，第5实施方式的割草机1E是与所述第1实施方式的割草机1A(参照图2)大致相同的结构，在主体部10上设置有嵌合部64这一点不同。
第5实施方式的嵌合部64是形成于主体部10的外壳11的前端部的内表面上的凹槽。嵌合部64在主体部10的左右方向上呈直线状延伸。
当保管第5实施方式的割草机1E时，使主体部10立起，将集草容器50安装于主体部10的底部。此时，通过将集草容器50的上框部52的后缘部嵌入到主体部10的嵌合部64，能够使集草容器50相对于主体部10稳定。
另外，第5实施方式的集草容器50通过嵌合部64被固定在主体部10的上部，并通过与收容部12的内表面抵接而被固定在主体部10的下部。如此，上下的固定部隔着割草刀片16而配置。通过该结构，集草容器50在上下左右的任意方向上都被稳定地固定 于主体部10，因此能够防止集草容器50相对于主体部10偏移，且能够有效地防止割草刀片16露出到外部。
上面对本发明的第5实施方式进行了说明，但本发明并不限定于所述第5实施方式，与所述第1实施方式相同，在不脱离其主旨的范围内能适宜地变更。
[第6实施方式]
接着，一边适宜地参照附图一边对本发明的第6实施方式详细地进行说明。如图9所示，第6实施方式的割草机1F是与所述第1实施方式的割草机1A(参照图2)大致相同的结构，在集草容器50上设置有挂绳65这一点不同。
在第6实施方式的集草容器50的罩55的后端部设置有两端部安装在罩55上的挂绳65。
然后，在使主体部10立起并将集草容器50安装于主体部10的底部时，通过将挂绳65勾挂在设置于主体部10的前端部的挂钩19上，能够使集草容器50相对于主体部10稳定。
另外，第6实施方式的集草容器50通过挂绳65被固定在主体部10的上部，并通过与收容部12的内表面抵接而被固定在主体部10的下部。如此，上下的固定部隔着割草刀片16而配置。通过该结构，集草容器50在上下左右的任意方向上都被稳定地固定于主体部10，因此能防止集草容器50相对于主体部10偏移，能够有效地防止割草刀片16露出到外部。
上面对本发明的第6实施方式进行了说明，但本发明并不限定于所述第6实施方式，与所述第1实施方式相同，在不脱离其主旨的范围内能适宜地变更。
[第7实施方式]
接着，一边适宜地参照附图一边对本发明的第7实施方式详细地进行说明。如图10所示，第7实施方式的割草机1G是与所述第1实施方式的割草机1A(参照图2)大致相同的结构，在集草容器50的罩55上设置袋部66这一点不同。
在第7实施方式的集草容器50的罩55的后端部设置有袋部66，该袋部66在将集草容器50安装在主体部10的底部时能覆盖主体部10的上部。
在第7实施方式的割草机1G中，在使主体部10立起并将集草容器50安装于主体部10的底部时，通过使集草容器50的罩55的袋部66覆盖主体部10的上部，由此能够使集草容器50相对于主体部10稳定。
另外，第7实施方式的集草容器50通过袋部66被固定在主体部10的上部，并通过与收容部12的内表面抵接而被固定在主体部10的下部。如此，上下的固定部隔着割草刀片16而配置。通过该结构，集草容器50在上下左右的任意方向上都被稳定地固定于主体部10，因此能防止集草容器50相对于主体部10偏移，能有效地防止割草刀片16露出到外部。
另外，由于被设置在罩55的上部的袋部66覆盖主体部10的前端部，因此，即使在主体部10向多个方向摇晃或倾斜的情况下，也能防止集草容器50相对于主体部10偏移或脱落。
上面对本发明的第7实施方式进行了说明，但本发明并不限定于所述第7实施方式，与所述第1实施方式相同，在不脱离其主旨的范围内能适宜地变更。
