新型的推草机主要以蓄电池作为动力系统，这种动力系统的特点是：工作噪声小、运行平稳、节能环保，被广大消费者接受。然而这种推草机的主要缺点是在工作时，靠人工推扶前进，消耗人工体力而且工作效率低，特别是再有一定坡度时单靠人工推扶前进更消耗体力，工作效率更低！
发明内容
本发明主要解决的技术问题是提供一种通过增加动力源和传动结构来解决在工作时靠人工推扶前进动力不足的问题，从而来实现推草机的自走功能的带自行走功能的园林工具动力系统。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种带自行走功能的园林工具动力系统，包括：电机、减速器和传动轴，电机将动力通过减 速器传输至传动轴上，传动轴带动轴上轮子转动，减速器包括小齿轮和大齿轮，小齿轮与电机输出端连接，大齿轮与小齿轮啮合连接，并装配于传动轴上，所述传动轴包括左轴和右轴，左轴和右轴之间通过连接轴连接，大齿轮装配于所述连接轴上，所述大齿轮上横向设有至少两根导向杆，导向杆之间装配有两个离心块，各导向杆上均套设有复位弹簧，且复位弹簧的两端分别压在两个离心块之间，离心块外围装配有旋转固定套，旋转固定套上设有与离心块匹配的卡扣结构，所述旋转固定套与传动轴固定连接。

具体实施方式
下面将对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，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它实施例，都属于本发明保护的范围。
本发明实施例包括：
一种带自行走功能的园林工具动力系统，如图1和图2所示，包括：电机14、减速器和传动轴，电机14将动力通过减速器传输至传动轴上，传动轴带动轴上轮子转动，减速器包括小齿轮15和大齿轮，小齿轮15与电机14输出端连接，大齿轮与小齿轮15啮合连接，并装配于传动轴上。
增加了动力系统，即电机14和减速器，和传动轴，合理的将电机14的动力传到轮子上，带动园林工具自动行走。在不需要这个动力系统工作时，园林工具还能在人工推扶的作用下前进或者后退。
如图2和图5所示，大齿轮和小齿轮15均设于减速器的壳体内，壳体包括 左壳体2和右壳体12，所述小齿轮15通过轴承17与固定于左壳体2上，左壳体2与右壳体12通过螺栓9连接，使其更稳定的传动。
在电机14的转动下，带动小齿轮15转动。根据转速比的关系Z1/Z2＝N2/N1，可以根据推草机实际转速的大小来设定Z1与Z2的大小，从而达到减速的目的。Z1、Z2分别代表大小齿轮15的齿数，N1、N2分别代表大小齿轮15的转速。
所述传动轴包括左轴1和右轴11，左轴1和右轴11通过轴承3分别固定在左壳体2和右壳体12上，左轴1和右轴11之间通过连接轴13连接，连接轴13与左轴1和右轴11之间采用过渡配合连接，可以减少工作时的跳动。
大齿轮装配于所述连接轴13上，大齿轮与连接轴13之间为间隙配合连接。防止连接轴13在转动时给大齿轮传递扭矩。
所述大齿轮上横向设有至少两根导向杆8，并通过压板7固定，导向杆8之间装配有两个离心块18，各导向杆8上均套设有复位弹簧6，且复位弹簧6的两端分别压在两个离心块18之间，离心块18外围装配有旋转固定套，所述旋转固定套包括分别装配于左壳体2和右壳体12内的左旋转固定套5和右旋转固定套10，左旋转固定套5和右旋转固定套10通过定位销轴4固定在左轴1和右轴11上。
各旋转固定套的内部上均设有卡扣结构。所述卡扣结构为设于左旋转固定套5和右旋转固定套10内壁上对称设置的凸台，便于离心块18与旋转固定套形成牙嵌式离合结构，传递扭矩。
本发明的具体工作过程如下所述：
启动电机14后，电机14与小齿轮15通过齿轮传动，将动能传给小齿轮15，小齿轮15与大齿轮16通过齿轮啮合将动能传给大齿轮16，这时大齿轮开始转动，由于大齿轮16与连接轴13是间隙配合，连接轴13以及与连接轴13相连接的左轴1和右轴11不会转动，即推草机不会自走。
然而在大齿轮16上有两个离心块18，在离心力的作用下，离心块18克服各自的复位弹簧6的阻力开始沿着导向杆8向外做离心运动，当离心块18分别与左旋转固定套5和右旋转固定套10接触后，便不会继续向外做离心运动，由于在左旋转固定套5和右旋转固定套10上有凸台，离心块18和旋转固定套形成牙嵌式离合结构，如图3所示，传递扭矩，这时左轴1和右轴11分别带动两端的轮子转动，实现推草机的自走，在这个过程中需实现，离心块18的离心力分别大于各自的复位弹簧6的拉力。
当电机14停止工作时，离心块18在复位弹簧6的作用下克服离心块18自身的重力，沿导向杆8，恢复到原来的位置，这时推草机可人工推扶的作用下前进或者后退，由于离心块18与旋转固定套已分离，不会有扭矩传递，如图4所示，另外在由于大齿轮与连接轴13是间隙配合，无摩擦力，左轴1及右轴11之间是过渡配合，推草机在人工作用下前进或者后退时，左轴1、右轴11及连接轴13会转动，而连接轴13与大齿轮无摩擦，固也会传递扭矩，即减速器结构与电机14完全分离。
本发明可以实现推草机的自走功能，即在电机的作用下，推草机可以自走，而在电机停止工作后，推草机可以在人工推扶的作用下工作；可以实现推草机自走与人工作用下前进或者后退转换自由，工作效率提高，而且减速器结构简单，成本低。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
