Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a seed acceleration device for a high-speed seeder. Background Technology

[0002] Currently, most precision seeders rely on the seed tube to fall freely into the furrow under their own weight during seeding operations. This method places high demands on the seeder's operating speed; the seeder's speed cannot be too high during operation. As the operating speed increases, problems such as uneven seed depth, uneven plant spacing, and even failure to bury seeds properly arise. Thus, the seeder's operating speed severely restricts the seeding efficiency. To maximize seeding speed and achieve optimal seeding precision, a high-speed seed acceleration device for seeders has been developed. Summary of the Invention

[0003] The purpose of this invention is to provide a seed acceleration device for a high-speed seeder to solve the problems existing in the prior art, enabling the seeder to achieve high-speed seeding and achieve the best seeding accuracy.

[0004] A seed acceleration device for a high-speed seeder uses an external device to provide high-pressure airflow to accelerate the falling speed of seeds during sowing operations, thereby shortening the seed travel time in the seed guide tube and reducing the probability of seed collisions in the seed guide tube, thus achieving uniformity of seed spacing during high-speed sowing.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides a high-speed seeder seed acceleration device, comprising an outer shell, a seed inlet tube, a seed inlet body, a seed outlet body, a seed outlet tube, an air duct, a set screw, an O-ring, and a blocking block. The outer shell is a three-way cavity structure. The air duct is fitted into the air duct hole (503) and locked with the set screw. The seed inlet tube is fitted into the seed inlet body and locked with the set screw. The seed inlet body is fitted into the seed inlet body hole (501). The seed outlet tube is fitted into the seed outlet body and locked with the set screw. The seed outlet body is fitted into the seed outlet body hole (502).

[0014] The seed inlet body is associated with the seed outlet body. The seed inlet body is partially contained inside the seed outlet body, and the seed inlet body and the seed outlet body partially form an annular chamber.
