此外，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。在本发明的描述中，“多个”的含义是两个以上，除非另有明确具体的限定。
在本申请中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
如图2-3所示，本发明提供一种打草机传动机构，包括机架1、打草头2、动力源3、电机4和锁定组件5。
其中，打草头2转动安装在机架1上，打草头2可在机架1上绕其旋转中心在预设角度α范围内转动。动力源3固定安装在机架1上，其用于提供动力。优选地，动力源3与机架1可拆卸连接以便于拆卸、更换或修理动力源3。电机4与动力源3电连接，电机4的动力输出端与打草头2的动力输入端传动连接，且电机4可随着打草头2一起转动。具体地，电机4通过螺栓固定连接在打草头2上，电机4的动力输出轴与打草头2的动力输入轴固定连接。锁定组件5固定安装在机架1上，其用于对打草头2进行锁定。优选地，机架1上设置有脚轮6，以便于推着打草机进行打草作业。
使用时，利用动力源3提供动力，驱动电机4转动，电机4驱动打草头2转动，从而达到打草的目的。且由于使用电机4直接驱动打草头2转动，且打草头2和打草头2均可在机架1上在预设角度范围内转动，因此，可以改变打草头2的工作角度以满足不同工作情况的需要。
在一个实施例中，锁定组件5包括限位盘51、限位杆52和锁定手柄53。
限位盘51的数量为两个，上述两个限位盘51相对设置在机架1上并与机架1固定连接，打草头2的两侧通过连接轴21与两个限位盘51转动连接，且至少一个限位盘51上开设有弧形限位槽511。限位杆52的第一端与打草头2固定连接、第二端滑动插设在弧形限位槽511内。在这里需要说明的是，限位杆52穿过弧形限位槽511。锁定手柄53安装在限位盘 51的远离打草头2的一侧并与限位杆52的第二端螺纹连接。
当需要调节打草头2的工作角度时，拧松锁定手柄53，当将打草头2旋转到合适的位置之后，拧紧锁定手柄53，即可对其进行锁定。
此结构的锁定组件5，结构简单。
在一个实施例中，限位槽上均匀开设有多个限位孔512，且限位孔512的内径大于限位槽的宽度，锁定手柄53的面向限位杆52的一端具有与限位孔512相适应的限位部531。
优选地，限位盘51呈U字形，弧形限位槽511包括分别开设在限位盘51两侧的第一限位部和第二限位部，且第一限位部与第二限位部连通，其中，第二限位部位于限位盘的面向打草头的一侧，且第二限位部的宽度大于第一限位部的宽度，限位销52呈阶梯状，其较大端与第二限位部相适应、较小端与第二限位部相适应。限位孔沿着第二限位部开设。
使用时，转动打草头2，使得限位杆52与其中一个小限位孔512相对应。拧上锁定手柄53。由于限位孔512的内径大于弧形限位槽511的内径，因此，在限位部531和限位孔512的作用下，使得锁定组件5对打草头2位置的锁定更加可靠。
此结构提高了锁定组件5对于打草头2的位置的锁定的可靠性。
在一个实施例中，限位孔512的数量为四个。
在一个实施例中，动力源3为发电机4或蓄电池。
在一个实施例中，预设角度α≤90°。
在一个实施例中，预设角度α＝90°。
在一个实施例中，弧形限位槽511与限位杆52相适应。
本发明的说明书中，说明了大量具体细节。然而，能够理解，本发明的实施例可以在没有这些具体细节的情况下实践。在一些实例中，并未详细示出公知的方法、结构和技术，以便不模糊对本说明书的理解。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或 者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围，其均应涵盖在本发明的权利要求和说明书的范围当中。
