Straw smashing, returning and rotary tillage all-in-one machine

The embodiment of the utility model discloses a straw smashing, returning and rotary tillage all-in-one machine, which relates to the technical field of agricultural machinery and is characterized bycomprising a rack, a driving device arranged on the rack and two rotary cutter shafts which are rotatably connected to the rack and positioned on two sides of the driving device, and the driving device drives the two rotary cutter shafts to rotate; and a plurality of first crushing reamers are arranged on the rotary cutter shaft at intervals. According to the technical scheme, the problems that inthe prior art, when a driving device drives a rotary cutter shaft to rotate and work, power is uneven, and the straw smashing and land rotary tillage depth effect is poor are solved. 本实用新型实施例公开了一种秸秆粉碎还田旋耕一体机，涉及农用机械技术领域，其技术方案要点包括机架、设置在机架上的驱动装置、转动连接在所述机架上且位于所述驱动装置两侧的两根旋刀轴，所述驱动装置带动两根旋刀轴转动；在所述旋刀轴上间隔设置有若干第一粉碎铰刀。本实用新型技术方案用以解决现有技术中驱动装置带动旋刀轴转动工作时动力不均匀、秸秆粉碎和土地旋耕深度效果不佳的问题。
