Deep-fertilization secondary-pressing full-width uniform sowing machine and sowing method

Abstract

The invention discloses a deep-fertilization secondary-pressing full-width uniform sowing machine, which relates to the field of agricultural machinery equipment, and adopts the technical scheme that the deep-fertilization secondary-pressing full-width uniform sowing machine comprises a rotary blade, a fertilization unit, a sowing unit and a soil covering unit which are arranged in sequence; the fertilizing unit comprises an upper fertilizer box, the fertilizer box is connected with a plurality of fertilizing pipes, and the lower ends of the fertilizing pipes are provided with fertilizer outlets; a lug is fixedly arranged on one side, facing the rotary blade, of the fertilizing pipe; the seeding unit comprises a seed box located at the upper part, and a spreading assembly and a precision seeding assembly are arranged on the lower side of the seed box; the soil covering unit comprises a main compacting machine and an auxiliary compacting machine which are sequentially arranged, the main compacting machine comprises a roller, the main compacting machine is adjacent to the precision seeding disc, and one side, far away from the main compacting machine, of the auxiliary compacting machine is connected with a hoe. Compared with the prior art, the device has the advantages that a deep fertilization mode is adopted during seeding, the problem that seeds are burnt by chemical fertilizers is effectively avoided, the seeding effect of full-width uniform seeding is achieved through the mode of combining scattered seeding and precise seeding, and a good foundation is laid for dense planting.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a deep fertilization secondary suppression full-width leveling machine and a seeding method. Background technique [0002] The seeder is a common type of agricultural equipment. Through mechanized operations, a series of operations such as rotary tillage, sowing, and fertilization can be realized. Traditional wheat full-width seeders usually use the form of spreading to achieve large-scale sowing. However, although the existing spreading machines seem to have a wide spreading area, it is difficult to avoid the defects of seeding coverage in some specific positions, and there is still room for optimization of the spreading effect. [0003] In addition, although many of the existing planters have the function of fertilizing, the combination of fertilizing and sowing does not have a very good effect on promoting seed growth.
