Disc harrow is mainly used for broken soil and peaceful land after plowing, can also be used for stirring soil, weeding, mixing fertilizer, shallow tillage after harvest, stubble removal, soil loosening before seeding, cover seed after seeding, sometimes in order to grab farming, moisture conservation can also be harrow tillage, is the most widely used in topsoil tillage machinery. The no-till seeder is a protective tillage machine with power disc cutting, clamping trencher fitted with power disc and simultaneous stratified sowing, which can complete many operations such as row direction cutting, simultaneous stratified sowing and middle and back suppression in the ground covered with straw. In this paper, a new no-tillage seeder is designed, which adopts no-power double-disc ditcher. The machine has simple structure, easy to use, strong effect of breaking soil, no entangling grass, high precision of sowing depth, uniform sowing, and can complete 6 rows of sowing in one operation, which is conducive to the growth of seeds, and can be used to hoe weeds in wheat fields after no-tillage sowing.
