Seed collecting device for improving crop seeding cavitation

The utility model provides a seed collecting device capable of improving crop seeding cavitation, relates to the technical field of crop seeding equipment, and solves the technical problems that a seeder is only suitable for hole seeding of large-grain crops and is poor in seeding precision. The seed collecting device for improving the crop seeding cavitation performance comprises a seed conveyingdevice with a seed conveying channel, a seed blocking piece which is arranged in the seed conveying channel and can open or close the seed conveying channel, a seed collecting part arranged on the seed blocking piece, and a control piece which is connected with the seed blocking piece and can control the seed blocking piece to act so as to open or close the seed conveying channel. According to the utility model, the seed blocking piece is arranged; seeds fall onto the baffle through the seed conveying pipe to stay for a short time; seeds are gathered through the arc-shaped groove, the seed blocking piece is controlle
