The invention relates to a high-efficiency energy-saving bidirectional double-furrow plough without a regulating wheel, relating to a tilting double-furrow plough without a regulating wheel, comprising a main beam, a front furrow plough, a rear furrow plough, a rotating shaft, a control lever, longitudinal frame plates and an adjusting plate. The rotating shaft is sleeved at the back of the main beam, the front furrow plough and the rear furrow plough are mounted at both gradient lower sides of the rotating shaft, the control lever is fixed above the front of the rotating shaft and matched with a baffle frame arranged on the main beam, the longitudinal frame plates are fixed at both sides of the front end of the main beam through a transversal frame plate and provided with longitudinal adjusting holes, the adjusting plate is fixedly connected with the longitudinal frame plates through adjusting shafts, adjusting screws of the adjusting plate are arranged in the adjusting holes, and the front part of the adjusting plate is connected with a tractor. The invention has the advantages of omitting adjusting wheel, lifting plough legs, saving materials, having less tilting resistance, reducing oil consumption, decreasing the operation cost, avoiding straw winding and improving the directional tilting efficiency, operates stably, has stable operation, high tilting quality, good effect on covering crop stubble and straw and facilitates subsequent field operation.
