AI Technical Summary

Technical Problem

The existing soybean seeders cannot achieve integrated soybean seeding and crop management, and have failed to effectively solve the problem of waterlogging and drainage in the field. It is easy to make the ground press too hard during the soil covering process, affecting the seedling rate.

Method used

An integrated seed machine suitable for soybean waterproof cultivation is designed, integrating walking mechanisms, rotary tillage mechanisms, ridge-raising mechanisms, seeding mechanisms, fertilization mechanisms, ridge-diffusion mechanisms and spraying mechanisms, realizing the unified operation of ridge-sowing seeds, ridge-diffusion drainage, fertilization and pesticide spraying.

Benefits of technology

Through this integrated seeding machine, efficient sowing, waterlogging and high yields of soybeans are achieved, which reduces disturbances in the field and soil damage, improves operating efficiency, and saves manpower and time.

Abstract

An integrated drill seeder suitable for waterlogging-resistant cultivation of soybeans comprises a walking mechanism, a rotary tillage mechanism, a ridging mechanism, a seeding mechanism, a fertilizing mechanism, an on-ridge ditching mechanism and a spraying mechanism, the seeding mechanism utilizes a brush roller to clean seeds adhered to a discharging roller except for a seed discharging groove, redundant seeds are prevented from falling down along with the discharging roller, and the seeding efficiency is improved. The seeds are prevented from being squeezed and damaged by the rotation of the two rollers by utilizing the flexible characteristic of bristles of the brush rollers; the soil scraping plate adopts an angle-adjustable structure, so that the soil scraping requirements of different strengths are met; a ridging height adjuster is used for adjusting the height between the ridging roller and the ground, so that the use requirements of different lands are met; the furrowing mechanism on the ridge is arranged, so that space is saved and the land utilization rate is increased while the requirement for water drainage on the same ridge is met; the fertilizing mechanism is additionally arranged above the rotary tillage mechanism, and the pesticide spraying mechanism is additionally arranged behind the press wheel, so that the rotary tillage of the land is completed, fertilizer application and pesticide spraying are realized, and time is saved for field management.
