The disc harrow has a sawtooth inclined edge for vertical cutting grass, stubble and ditching during the rotation process. A grid unit is arranged at the rear of the sheet, and the grid unit is fixed on the frame by bolts. The grid unit is provided with a grid that intercepts the chopped weeds and straw thrown back by the disc rake. Chopped weeds and stalks fall onto the plow layer, and a precision sowing suppression device is installed behind the grid unit. The precision sowing suppression device includes a seed box, a sowing disc, a sowing pipe and a suppression wheel, and corn is placed in the seed box. Seeds, the seed box is connected with the sowing pipe, the pressing wheel is located behind the disc harrow, the pressing wheel is connected with the frame through the fixing shaft of the pressing wheel, and the corn seeds are covered with soil for pressing after spreading the corn seeds, and the ground wheel is fixed on the rack.

When the sowing starts, the sowing disc in the seed box rotates, and the corn seeds are taken out from the sowing disc, and are sowed on the subsoiled cultivated land through the sowing pipe. By adjusting the position of the sowing disc, the corn seeds are precisely controlled. the seeding rate.

Further, in order to improve the loosening effect of the subsoiling shovel, the lower part of the subsoiling shovel is set in an arc shape, and the shovel tip angle α of the lower part of the subsoiling shovel is set at 12°-16°, which is more conducive to loosening the soil.

Further, in order to adjust the strength of the suppression, an elastic device is connected between the frame and the pressing wheel, and the degree of suppression can be regulated by controlling the size of the elastic force. The elastic device can be a spring.

Further, one or more sets of precision seeding suppression devices are arranged side by side, and the distance between adjacent precision seeding suppression devices can be adjusted. 2-5 sets of precise sowing suppression devices can be arranged side by side. As an optimization, 3 sets of precision sowing suppression devices can be arranged side by side.

With the above structure, the subsoiling operation is carried out before corn sowing, and the stubble removal operation is carried out after the subsoiling is completed. Through the rotation of the disc harrow, the root stubble is crushed and grooved, which is convenient for subsequent sowing and beneficial to the growth of crops. Equipped with a precision sowing suppression device to achieve precise control of sowing, while proper suppression is conducive to moisture conservation and emergence.

The machine rationally integrates subsoiling operation, disc harrow stubble removal and furrowing operation, precision seeding and suppression operations, and can complete subsoiling, disc harrow vertical stubble removal and ditching, corn sowing, soil covering and suppression at one time. Agronomy changes the separate operations in the past to one-time completion, saves manpower, material resources and farming inputs, and competes for farming time. At the same time, it increases soil fertility, increases production and income, and improves the ecological environment. The utility model has the advantages of reasonable design, simple structure, broad market prospect, strong practicability and popularization and application value.
