Sowing machine with functions of subsoiling, fertilizer application as well as furrowing and bed building

Abstract

The invention relates to a sowing machine with functions of subsoiling, fertilizer application as well as furrowing and bed building. The sowing machine comprises a gearbox, a traction rack, an anti-winding mechanism, a zone subsoiling mechanism or a strip-shaped deep and rotary tillage mechanism, a soil loosening and gathering mechanism, a fertilizer application mechanism, a furrowing and bed building mechanism, a sowing mechanism, a vertical positioning mechanism, a compacting mechanism, a pesticide sprayer, a related transmission mechanism and the like, wherein the anti-winding mechanism can effectively prevent the straw winding problem, continuous sowing operation of the machine is guaranteed, the operation efficiency is improved, the problem about in-place burning of straw is solved, and the straw burning phenomenon is eliminated fundamentally; zone subsoiling is environment-friendly and energy-saving, and by means of subsoiling or deep and rotary tillage, plow pans are broken, the water-holding capacity is improved, the surface vegetation coverage is increased, and flowing dust pollution in air is reduced; by means of the furrowing and bed building mechanism, the sowing quality and the thickness of covering soil can be accurately controlled, shallow seeding of wheat can be realized, the problems of seedling weakness, death caused by drought, death caused by freezing, late lodging and the like caused by uneven sowing deepness by means of a traditional sowing machine are solved fundamentally, the seedling emergence rate is greatly increased, and quality seeds are saved.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a subsoiling and fertilizing ditch pressing bed-making seeder. Background technique [0002] Today, there are two main ways of cultivating wheat: one is to use a vibrating subsoiling shovel to subsoil the soil where the straw is returned to the field, and then use a no-tillage seeder to sow the seeds. The subsoiling effect is invisible and unintuitive, and it is difficult for farmers to accept it. It has been promoted but not popularized for many years; another farming method is to mechanize rotary tillage on the soil where the straw is returned to the field, and then mechanized sowing. The amount of weeds is very large, and the loose soil after rotary tillage has a large content of straw weeds. After sowing, the seedlings often hang and freeze to death at the seedling stage, and the problem of volts in the later stage; moreover, the sowing depth of today's traditional wheat seeders is ...

[0002] Today, there are two main ways of cultivating wheat: one is to use a vibrating subsoiling shovel to subsoil the soil where the straw is returned to the field, and then use a no-tillage seeder to sow the seeds. The subsoiling effect is invisible and unintuitive, and it is difficult for farmers to accept it. It has been promoted but not popularized for many years; another farming method is to mechanize rotary tillage on the soil where the straw is returned to the field, and then mechanized sowing. The amount of weeds is very large, and the loose soil after rotary tillage has a large content of straw weeds. After sowing, the seedlings often hang and freeze to death at the seedling stage, and the problem of volts in the later stage; moreover, the sowing depth of today's traditional wheat seeders is not easy. Grasp, different depths, resulting in weak wheat seedlings of too deep wheat seedlings, freezing to death and drought death of too shallow wheat seedlings, etc. In order to ensure the basic seedlings of wheat per acre, farmers had to increase the wheat sowing rate year by year, resulting in a large number of wheat seedlings. waste of wheat seed
