High-speed precision seeder

Abstract

The invention provides a high-speed precision seeder, belonging to the technical field of seeders. According to the high-speed precision seeder provided by the invention, a seeding single frame is connected with a frame assembly, a seed box is arranged at the upper part of the frame assembly; a disk ditching device, a sliding knife ditching device, a soil covering device and a compacting and depth-limiting wheel are sequentially arranged on the seeding single frame from front to back; a seeding depth regulating rod is connected between connecting rods of the seeding single frame and the compacting and depth-limiting wheel, a seeding device and a seed guide pipe are fixed at the middle part of the seeding single frame, and a ditching device front pressure spring and a ditching device back pressure spring are respectively mounted at the front part and the back part of the sliding knife ditching device. The high-speed precision seeder provided by the invention has the beneficial effects of strong adaptability of the seeder to soil during high-speed seeding, smooth seed ditches, stable ditching depth and close contact between seeds and soil at the bottom of each ditch, and can significantly improve the transverse distribution and the seeding depth of the seeds in the ditches and greatly improve the seeding operation quality.

Description

technical field [0001] The invention relates to a high-speed precision seeder, which belongs to the field of seeder technology. Background technique [0002] Seeding machinery is one of the most basic production tools in agricultural production. Most high-speed precision seeding machinery uses disc openers or sliding knife openers. The disc opener can cut off the residual roots in the soil and has strong adaptability to the soil, but there are problems such as uneven seed furrows during high-speed sowing, which affect the lateral distribution of seeds in the furrow and the sowing depth; the sliding knife opener can A flat seed ditch is opened so that the seeds can be in close contact with the ditch soil and absorb more water for germination, but there are problems such as unstable ditch depth during high-speed sowing operations. Contents of the invention [0003] The purpose of the present invention is to solve the problems in the above-mentioned prior art, that is, when ...
