Double-line vibration deep riper

The utility model relates to a deep tillage cultivator designed for carrying out a coexistence of deficiency and excess, and an interval deep tillage plowing. The deep tillage cultivator consists of a double splint beams frame with a suspension bracket and a double vibration lever draft arm with a deep tillage plough, wherein a transmission shaft connected with a tractor dynamic shaft causes the two deep tillage ploughs which are driven by the two vibration lever draft arms vibrate up and down via a transmission chain and a transmission crankshaft. The deep tillage cultivator has the advantages of small traction resistance, good tillage effect, and the deep tillage cultivator is capable of meeting the operation demand of interval tillage, thereby the deep tillage cultivator is an ideal matching implement of a small four-wheel tractor for deep tillage operation.
