The seed collection device based on image recognition according to claim 5 is characterized in that a discharge port (13) is provided on the end side of the screening box (3), the discharge port (13) is connected to the lower ends of the sieve plate a (201) and the sieve plate b (202), and a collection box (12) is placed below the discharge port (13).

8. The seed collection device based on image recognition according to claim 4 is characterized in that a debris removal port (16) is opened on the side of the screening box (3), and the plurality of baffles (101) are distributed at equal distances.

9. A seed collection method based on image recognition according to any one of claims 1 to 8, characterized in that it comprises the following steps:

S1. The collected seeds are placed inside the material holding box (1101), and the small motor (1108) is started to work. The output end of the small motor (1108) drives the incomplete gear (1107) to rotate, thereby driving the slide plate (1102) to move back and forth through the cooperation of the incomplete gear (1107) and the toothed plate (1106), so that the first notch (1103) and the second notch (1104) overlap intermittently. When the first notch (1103) and the second notch (1104) overlap, the seeds in the material holding box (1101) fall into (5);

S2, starting the blower (8) to work, the blower (8) draws air into the cavity (104) through the air delivery pipe (9), and blows the air evenly onto the seeds through a plurality of equally spaced blowing holes (103), so that the seeds continuously fall onto a plurality of baffle plates (101) when falling in the air separation cylinder (5), thereby effectively slowing down the falling speed of the seeds in the air separation cylinder (5);

S3, the contact time of the wind blown out through the blowing holes (103) in the seeds, the wind blown out by the multiple blowing holes (103) fully blows out the shriveled seeds and impurities in the seeds from the mesh plate (15);

S4, start the swing motor (701) to work, so that the swing motor (701) drives the connecting rod (702) to swing back and forth within a fixed angle, thereby driving the knocking rod (703) to knock the screen plate b (202)

The bottom of the screen plate is struck back and forth, causing the screen plate b (202) and the screen plate a (201) to vibrate continuously.

This enables sieve plate b (202) and sieve plate a (201) to perform efficient screening.
