AI Technical Summary
The seed box of existing grain planters is prone to clogging of the discharge port due to seed type, moisture content, or uneven spreading, which affects the uniformity and continuity of seeding.
A seed box designed to prevent blockage includes a connecting plate, a piercing needle, a connecting cylinder, an elastic element, and a cam mechanism. The piercing needle enters the seed outlet tube to clear blockages, and the elastic element and cam drive the piercing needle to move up and down at high frequency to ensure unobstructed flow in the seed outlet tube.
Effectively clear blockages in the seed box, ensuring continuous and efficient sowing, avoiding downtime for cleaning, and improving overall sowing efficiency.
