During the operation of wheat no-tillage seeding machine, the power of the tractor is directly transmitted to the middle gearbox of the seeding machine through the transmission shaft, and drives the left and right cutter shaft for rotary cutting operation. When the cutting tool is in contact with the ground, the rotary tillage knife in the front will cut off part of the straw or stubble and bury it into the soil for ribbon roiling. Push the straw and stubble to both sides of the planting and fertilizing position. The depth limiting suppression wheel at the back rotates by friction between its own mass and the ground, and the seeding and fertilizer discharge mechanism are driven by the chain transmission mechanism to implement seeding and fertilizer discharge. The discharged seeds and fertilizer enter the furrow opener through the seed transport pipe and fertilizer transport pipe respectively, and then fall into the opened furrow successively. Then the suppressing wheel compacts the soil in the furrow and completes the no-tillage mulching fertilization sowing operation.
