Non-tillage precision seeder

Abstract

A non-tillage precision seeder comprises a machine frame, a traction frame, a furrowing and fertilization mechanism, a power drive mechanism, a non-tillage stubble cleaning mechanism, single seeding bodies, an earthing and compacting mechanism, seed discharging devices, a profiling mechanism, a seed fertilizer box and markers. The non-tillage precision seeder is reasonable in structure and reliable in performance, operation line spacing, operation depth, row spacing, seeding quantity and fertilizing amount can be conveniently adjusted within a larger range, stubble cutting, furrowing, fertilization and seeding can be directly performed in wheat stubble field which is not turned over, fertilization and seeding can be also performed after corn stubble field is subjected to straw turnover, and furrowing and fertilization, stubble cutting and soil loosening, furrowing and seeding, earthing, compaction and other working procedures are completed at a time. In addition, by the adoption of a non-tillage mode, water and soil loss can be prevented, drought and waterlogging resistance can be achieved, organic matter of soil can be increased, a soil structure can be improved, a large amount of working time and seed resources can be further saved, the yield can be increased, and the like. Thus, the non-tillage precision seeder is wide in application range and can meet the agricultural technology requirements of various regions.

Description

technical field [0001] The invention relates to a no-tillage precision seeder, which belongs to the field of agricultural machinery. Background technique [0002] With the progress of society and the development of agricultural mechanization, especially in order to reduce the use of chemical fertilizers, increase the fertility of the soil, improve the quality and yield of crops, and promote the practice of returning straw to the field, no-tillage seeders have begun to be well established and popularized. However, due to the unreasonable design of the no-tillage seeders on the market, they cannot cut off the straw covering the ground well when sowing, so they cannot meet the width and depth of the ditch, so that the sown seeds are exposed outside, resulting in the seeds not being able to germinate. , which affects the quality of sowing, reduces the emergence rate, needs to replenish seedlings, or even re-seeding, resulting in reduced production and waste of seed working hours...

[0002] With the progress of society and the development of agricultural mechanization, especially in order to reduce the use of chemical fertilizers, increase the fertility of the soil, improve the quality and yield of crops, and promote the practice of returning straw to the field, no-tillage seeders have begun to be well established and popularized. However, due to the unreasonable design of the no-tillage seeders on the market, they cannot cut off the straw covering the ground well when sowing, so they cannot meet the width and depth of the ditch, so that the sown seeds are exposed outside, resulting in the seeds not being able to germinate. , affects the quality of sowing, reduces the emergence rate, needs to replenish seedlings, or even re-seeding, resulting in reduced production and waste of seed working hours, which is not conducive to the promotion and use of straw returning to the field
