STRAW RETURNING, DEEP SCARIFICATION, ROTARY TILLAGE, PRESSING COMBINED SOIL PREPARATION MACHINE

The present disclosure relates to the technical field of agricultural machinery equipment, and specifically relates to a straw returning, deep scarification, rotary tillage, pressing combined soil preparation machine, including a stand. A traction frame is mounted in front of the stand. An oil cylinder is arranged on each of the front part and the rear part between the traction frame and the stand. Two ends of the oil cylinders are respectively hinged with the traction frame and the stand to form a traction frame and stand hinge structure to form a frame. Trapezoid side plates are correspondingly mounted at the middle parts of two sides of the traction frame, and the inner sides of the two trapezoid side plates are provided with bearing pedestals. Bearings are mounted in the bearing pedestals. A working shaft is mounted between the two bearings. A blade is mounted on the working shaft. The straw returning, deep scarif1cation, rotary tillage, pressing combined soil preparation machine has power, so a high-power tractor is not needed. The tillage depth can be 30 centimeters, and the deep scarif1cation shovel can break a plough pan. The soil preparation machine has the advantages of capability of doubling the work eff1ciency, capability of thoroughly smashing the straws of the crops, good stubble cleaning effect, and the like, and meets the requirements for crop planting.
