In order to prevent the fertilizer from volatilizing, the rotary tiller 7 drives the rotary tiller to loosen the cotton field through the tractor power output shaft, and at the same time buries the fertilizer in the soil, and then is installed on the rotary tiller. The four furrowing plows on the front, back, left and right sides of the machine 7 open two drainage ditches 30 cm wide and 20 cm deep for the cotton field, and then the soil pressing driving wheel 5 dragged by the tractor drives the 18-tooth spoon wheel seeder to sow through the sowing transmission chain 6. In order to prevent the sown cotton seeds from losing air, the soil pressing driving wheel 5 compacts the cotton field. The roller body of the soil covering roller adopts a hollow skeleton design, and the skeleton adopts round steel in a "Z" shape and is evenly distributed on the roller body. The design scheme greatly enhances the friction between the soil covering roller and the ground, so that the soil covering roller can achieve smooth rolling without slipping, ensuring In order to improve the transmission efficiency of the seeder and the reliability of the soil covering quality, a covering wheel is designed on the covering roller body of the cotton direct seeding machine, and the covering wheel is provided with a mud scraper, which solves the problem that the conventional single covering wheel is easy to stick to the soil and slip and cannot effectively cover the soil.
