The invention discloses a
cutting, shifting and blocking preventing device, and belongs to the technical field of
agricultural machinery. The
cutting, shifting and blocking preventing device comprises a spindle, connecting sleeve plates, inclined plates, a breaking and
cutting device and stubble shifting and blocking preventing devices, wherein the breaking and cutting device is mounted in the middle of the spindle, two groups of stubble shifting and blocking preventing devices are symmetrical about the breaking and cutting device and connected to two ends of the spindle, stubble shifting wheels of the stubble shifting and blocking preventing devices and breaking and cutting discs of the breaking and cutting
device form deflection angles, and accordingly, the two symmetrical stubble shifting wheels are mounted on two sides of the end part of the breaking and breaking and cutting device in a splayed manner and simultaneously backwards shift stubble and laterally push stubble,
straw and weeds; the connecting sleeve plates are symmetrically connected between the breaking and cutting device and the stubble shifting and blocking preventing devices on the spindle and are simultaneously connected with the stubble shifting and blocking preventing devices respectively; and during working, the two connecting sleeve plates are connected with a no-
tillage planter for corn
ridge culture respectively. The device can
cut the stubble,
straw and weeds, can shift the stubble, can throw the
straw, the stubble and the weeds to the rear side and can push the straw, the stubble and the weeds to furrows on two sides, a clean seed
bed is formed on a
ridge, blocking is reduced, and the breaking and cutting quality is guaranteed.
