Precision corn seeder adopting one man operation

Abstract

The invention discloses a precision corn seeder adopting one man operation and aims to control plant spacing and depth of seeding precisely. The precision corn seeder comprises a seed guide pipe device, a plant spacing adjusting device, a seeding port controlling device and a handle, wherein the seed guide pipe device comprises a seed guide pipe and a seed feeding box; the plant spacing adjusting device comprises a plant spacing adjusting inner pipe, a plant spacing adjusting outer pipe, a front support rod, a seed hole positioning rod, a fastening screw, a U-shaped connecting piece and a rotating shaft; the rear part of the plant spacing adjusting inner pipe is inserted into the plant spacing adjusting outer pipe, the front end of the plant spacing adjusting inner pipe extends out and is welded with the front support rod; the fastening screw is mounted at the front end of the plant spacing adjusting outer pipe, and the rear end is welded with the upper part of a front baffle of a seeding port assembly; the seed guide pipe is sleeved with the U-shaped connecting piece, inner sides of the front ends of two arms of the U-shaped connecting piece are welded with the plant spacing adjusting outer pipe and the upper end of the front baffle of the seeding port assembly, and two arc-shaped sides at the rear ends are mounted on the rotating shaft through hole punching; the rotating shaft is welded at the lower end of the seed guide pipe; the seeding port controlling device comprises the duckbill seeding port assembly, a seeding depth controlling plate, a spring upper stop lever, a spring and a forward-pushing-to-position rod; the duckbill seeding port assembly comprises the front baffle, a rear baffle and side baffles.

Description

technical field [0001] The invention relates to a corn precision sowing device operable by one person. Background technique [0002] Artificial point seeding of corn is another important sowing method besides mechanical sowing. Its advantages are low input cost, high sowing quality, less soil moisture loss, and flexible time. The existing artificial corn on-demand device cannot meet the current high-density and high-precision planting requirements for corn. The main performance is that the suitable sowing density and production demand are not in good agreement, the sowing depth is difficult to control, the sowing port is prone to seed storage and missed sowing, and the self-weight design is not scientific. , using laboriously. The above-mentioned deficiencies have reduced the performance and advantages of the whole device. The phenomenon of lack of seedlings and broken ridges in the field is relatively common, the uniformity of the population is poor, and the corn yield is ...
