The rotation of the large gear will not only drive the fixed shaft to rotate, but also drive the small gear to accelerate. The rotation of the fixed shaft drives the unloading roller to rotate. The rotation of the unloading roller drives the rectangular groove to rotate, so that the seeds can enter the corresponding rectangular groove. As the unloading roller rotates, when the rectangular groove with seeds is transferred to the sand bucket, the sand inside the sand bucket will fall onto the seeds, and the rotation of the small gear drives the lever to accelerate. Rotation. It should be noted that each time the discharge roller discharges the material into the rectangular trough, the large gear drives the discharge roller to rotate a certain angle, the small gear rotates one circle, and the rotation of the dial lever will drive the slide plate to move and make the spring rod generate elastic force. The movement of the slide plate will connect the water outlet pipe and the through hole, and the rectangular trough with sand and seeds continues to rotate, then the water inside the water tank will flow into the rectangular trough with sand and seeds. When there are seeds, sand and water inside the rectangular trough, as the discharge roller rotates, the seeds, sand and water will fall into the cultivation trough, and as the discharge roller rotates and moves, the seeds, sand and water will be evenly distributed in the cultivation trough on the cultivation tray.
