The main features are high fertilization efficiency, uniform planting, improvement of soil structure and good wheat Growth and development conditions. Deep loosening of soil is an important way to improve crop yield, which is of great significance to promote the development of agriculture and ensure the high yield of Chinese crops. During the tractor running forward, the chisel-shaped deep shovel is deepened below the ground for about 30 centimeters, and the process of deep loosening of the soil is completed under the tractor traction. At the same time, the engines power is transmitted to the chisel through the universal joint and the side gearbox Shaped tillage machine. The rotary tillage mechanism adopts the full rotation method to carry out the comprehensive rotation of the soil of the wheat seedling line, and the depth of the rotary tillage is about 15 centimeters. Immediately after the rotary tillage mechanism of the arrow-shaped opener out of the wheat seedling, for wheat planting to prepare. The crusher wheel drives the power through the chain drive, forcing the outer shearing unit and the extruder to rotate. The seed of the wheat seed is discharged into the wide seedling through the guide tube, and the width of the wide seedling 12 cm, consistent with the width of the seedling belt, to achieve broad seedling with sowing; row of fertilizer through the fertilizer pipe and deep loose shovel connected to the deep loose shovel to complete the deep soil while deep fertilization. The machine is not set off the cover plate is due to the rotation of the knife after the pile of soil encountered after the shelter cover both play the
