The invention discloses a lawn weeding machine capable of increasing the torque based on a speed reducer, which comprises a weeding machine shell. A working cavity is formed in the weeding machine shell, and a weeding assembly is arranged in the working cavity. The weeding assembly comprises a motor fixedly arranged on the inner wall of the upper side of the working cavity, a first rotating shaftwhich is in power connection to the lower end of the motor and extends downwards to the outside, and a blade which is arranged on the outside and is fixedly connected with the first rotating shaft. According to the lawn weeding machine, the left-right movement of the rotating blade can be controlled by changing the steering direction of wheels, so that over-high vegetation on the lawn is automatically pruned and cut off. When the weeding machine is used for weeding on the lawn with a certain slope, and a detection rotating rod is in contact with a signal detection block for a long time, that is, the lawn is steep, an air cylinder can be controlled to enable a telescopic rod to extend, so that the power of the wheels is led out by a speed reduction assembly, the rotating torque of fifth rotating shafts is increased, and accordingly the weeding machine can better work on the slope lawn.

    本发明公开了一种基于减速器增加扭矩的草坪除草机,包括除草机壳体,使所述除草机壳体内设有工作腔,所述工作腔内设有除草组件,所述除草组件包括固设于所述工作腔上侧内壁的电机、动力连接于所述电机下端且向下延伸至外界的第一转动轴、设于外界且和所述第一转动轴固定连接的刀片,本发明能通过改变车轮的转向,控制转动的刀片的左右移动,从而实现对草坪上过高的植被进行自动修剪割除,且除草机在具有一定坡度的草坪进行除草时,当检测转杆长时间和信号检测块接触时,即草坪坡度较陡时,能控制气缸使得伸缩杆伸长,从而使得车轮动力由减速组件引出,增大第五转动轴转动的扭矩,使设备能更好地在斜坡草坪上工作。
