Corn no-tillage seeding and fertilizing machine

Abstract

The invention discloses a corn no-tillage seeding and fertilizing machine, and belongs to the technical field of agricultural machinery. The corn no-tillage seeding and fertilizing machine comprises a machine frame, a deep scarification, fertilization and soil preparation mechanism, a seed and fertilizer application mechanism, a seeding mechanism, a soil covering mechanism and a pressing mechanism, and the deep scarification, fertilization and soil preparation mechanism, the seed and fertilizer application mechanism, the seeding mechanism, the soil covering mechanism and the pressing mechanism are sequentially arranged on the machine frame. The seed and fertilizer application mechanism and the seeding mechanism are correspondingly connected with a walking wheel shaft through chain transmission; a seed and fertilizer discharge pipe is arranged at the working rear end of a furrowing blade of the seeding mechanism; the fertilizer is arranged at the bottom of a seed furrow; and a seed outlet of a seed discharging pipe of the seeding mechanism is arranged behind the furrowing blade, so that the fertilizer discharged from the seed fertilizer and the sown seeds are arranged at different positions and different depths of the seed furrow. According to the corn no-tillage seeding and fertilizing machine, the fertilizer does not burn seedlings, the seeds can well absorb the fertilizer, and the germination of the seeds is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a corn no-tillage seeding and fertilizing machine. Background technique [0002] The climate in northern China is arid, and soil erosion is serious. Conservation tillage has been vigorously promoted in recent years. Conservation tillage technology is an advanced agricultural farming technology aimed at reducing wind erosion and water erosion, protecting the ecological environment, saving costs and increasing income, and improving farmers' lives; however, the research on key technologies of ridge farming conservation tillage is weak, and the level of technology integration is low. From the early 1990s, nearly 20 years of research, several no-tillage seeders have been tested in the Northeast ridge farming area. In 2006, the U.S. Buffalo ridge no-tillage seeder was tested in the suburbs of Shenyang City. The quality of stubble breaking and ridge clearing is good. ; B...

Problems solved by technology

[0003] In view of the existing corn no-tillage seeders mentioned above, the row spacing and plant spacing of planting cannot be accurately controlled, and corn is easy to be emptied or densely planted, and it is impossible to apply seed fertilizer in a precise amount, which affects the sowing effect and the growth of corn in the later stage, and cannot realize deep fertilization and seeding. synchronous use of fertilizer; in addition, it is impossible to clean up the field surface before corn sowing, soil preparation, deep loosening and fertilization, which cannot meet the technical problems of modern agricultural production and planting needs. Seeding, fertilization, and cleaning, soil preparation, deep loosening and fertilization before sowing, to promote the subsequent nutrient supply of corn seed germination and rooting
