The grass pulling, crushing, killing, field flattening, direct seeding and seed covering parts are sequentially assembled on a chassis of a small and medium tractor from front to back, and are driven and operated by a power transmission system and an operating system of the tractor.

Each coulter is composed of 4 sharp Y-shaped edges, more than 6 coulters are fixed on a rotating shaft through a shaft hole and a gear and then connected with the power of a power transmission system of a tractor through power transmission in a transmission arm to form a grass poking component. More than 6 groups of cross-shaped steel members are serially connected on a rotating shaft with a gear, staggered with a group of m-shaped steel members, connected with the power of a power transmission system of a tractor through the power transmission in a transmission arm, and fixed behind a grass poking part to form a crushing part. The middle of the pipe wall of the lower end of the exhaust pipe is provided with an air injection opening, the upper end of the exhaust pipe is connected with an exhaust port of a tractor, and the exhaust pipe of the lower end is arranged behind the crushing component to form a killing component. A straight pipe is arranged in an L-shaped steel component with two ends capable of lifting to form a field flattening component. A row of funnels with grass dividers in the front are controlled by valves to form a direct seeding part. A rotatable carriage mounted on the vertically adjustable steel column to form a seed covering component.

The method comprises the steps of driving a one-time cultivating and direct seeding agricultural machine into a waterless or moist farmland, starting an operation system to operate according to an operation method of a tractor, enabling a driving wheel to move forwards, enabling a grass poking component to rotate forwards at a high speed, poking weeds with the depth of 3-5cm by a coulter, breaking and smashing the weeds at a high speed through a smashing component, enabling the weeds to be smashed, enabling grass roots to be wound on the smashing component, scalding or burning the grass roots by 200-plus 400-DEG C high-temperature tail gas sprayed by a weeding component according to a protein heating denaturation principle to enable the weeds to lose protein activity, then throwing the weeds into the farmland, flattening the farmland through a flattening component, then filling rice seeds for accelerating germination, opening a valve, separating the weeds through a grass separator, adjusting the valve, controlling the rice seeds to be uniformly and directly seeded into a proper amount of shallow ridges without grass which are cut by the grass separator, and covering the seeds through a seed covering component.

Due to the adoption of the scheme: the utility model does not need to replace a plurality of sets of farm tools and is not full of water for irrigation; the utility model replaces the procedures and elements of plowing, cultivating, leveling land, planting and the like, is completed at one time, saves the cost of farm implements, irrigation cost and a large amount of time, and saves a large amount of manpower by changing planting into direct seeding. The utility model is convenient for farmers, saves time, labor, water, oil, fertilizer and seeds, completes the plowing to the direct seeding at one time, avoids the loss of soil surface nutrients, can directly seed, has high germination rate and survival rate, and is superior and more efficient than the background technology.
