Front and rear straight row cylinders and rear straight row cylinders are arranged side by side. The front straight row cylinder and the rear straight row cylinder are respectively vertical protruding, and the front and rear straight barrels are arranged along the transverse steps. During operation, the crushing roller crushes and picks up the straw, and throws the straw backward along the tangential direction. The half-width straw of the crushing roller is thrown to the booster impeller, and the booster impeller cooperates with the deflector to push the straw to the rear auger; the other half-width straw of the crushing roller is thrown to the front Auger. The straw is evenly, smoothly and accurately discharged into the two pre-opened deep trenches through the front straight row and the rear straight row. After the ridge is combined, the goal of mechanized deep burial of the straw and long-term fertilization of the soil is achieved, and the mechanization and high efficiency are achieved. The straw is returned to the field in depth. Compared with the traditional straw returning machine, it can return large doses to the field, avoiding the problems that the straw surface cover hinders the soil preparation and the mixing of the straw and the soil after the soil preparation affects the spring sowing. And it is not limited by the thickness of the soil cultivation layer and the size of the plot. Therefore, the effects of large dosage of straw returning to the field, good effect of returning to the field and strong adaptability are obtained.
