s2, adjusting the position of a plough coulter (1124) on a fixed column (1121) according to the depth of ploughing required, when the position of the plough coulter (1124) is adjusted, a side sliding strip (1125) slides in a side sliding groove (1122), the fixed column (1121) slides in a sliding sleeve (1123), after the position of the plough coulter (1124) is adjusted, the sliding sleeve (1123) is fixed on the fixed column (1121) through a positioning screw (1126), so that the position of the plough coulter (1124) is fixed, meanwhile, the fixed column (1121) slides on the sliding strip (1111), so that an earth turning device (112) is adjusted to a proper position, the position of the fixed column (1121) on the sliding strip (1111) is fixed through a fixing nail (1128), and the position of a depth limiting device (113) is adjusted according to the position of the earth turning device (112), so that a sliding block (1131) slides on the sliding strip (1111);

s3, a screening device (12) is arranged according to the content of stones in the soil to be plowed, when no large stones exist in the soil, the screening device (12) is arranged on the plowing device (11) in a turnover mode, so that the normal plowing of the plowing device (11) is not affected by the screening device (12), when a certain amount of large stones exist in the soil, the screening device (12) is arranged on one side of the plowing device (11), meanwhile, the turnover condition of the bearing device (122) is adjusted according to the softness of the soil, when the soil is soft, the T-shaped sliding block (1214) is arranged at one end close to the bearing device (122), so that the bottom of the bearing device (122) is attached to the soil, the bearing device (122) can conveniently collect the stones in the soil, when the soil is hard, the T-shaped sliding block (1214) is adjusted to a position far away from the connecting strip (1112) in order to enable the bearing device (122) to be normally used, enabling the soil turning device (112) to vertically screen stones in soil;

s4, when the device is dragged and moved, soil is plowed by the colter (1124), the plowed soil is overturned towards two sides along the side face of the colter (1124), the flat guide plate (1133) is contacted with the soil, the soil plowed by the colter (1124) is prevented from being plowed deeply, the soil plowed by the colter (1124) is received by the receiving device (122), soil particles leave from gaps between the barrier strips (1223), and large stones in the soil are left in the receiving device (122).
