S2, when the seed feeding height needs to be adjusted, unscrewing a locking bolt connected with the shell and the seed feeding positioning plate (11), rotating the seed feeding positioning plate (11) to reach a preset position along the radian direction of the side surface of the seed discharging wheel (5), and screwing the locking bolt to finish the seed feeding height adjustment;
S3: during operation, the sprocket (10) drives the seed metering wheel (5) to rotate anticlockwise through the rotation shaft (7), seeds in the seed box (1) enter the seed metering pocket (5 b) of the seed metering wheel (5) from the seed inlet (5 a), when the seed metering pocket (5 b) breaks away from the population, redundant seeds slide out of the seed metering pocket and fall back into the seed box (1) by virtue of self gravity, and along with the continuous rotation of the seed metering wheel, when the seed feeding opening (5 e) of the seed metering channel (5 c) is lower than the seed metering pocket (5 b), the seeds in the seed metering pocket slide down and are concentrated between the seed metering channel (5 c) and the seed metering locating plate (11), rotate along with the seed metering wheel (5), and when the seed metering opening (5 e) of the seed metering channel (5 c) leaves the circular arc panel of the seed metering locating plate (11), the seeds fall out from the seed outlet of the shell (8).
