Manual Fertilizer Seeder uses a rotating cup feeder. The feeder is composed of several feeding cups, and the diameter of the feeding cup corresponds to the size of the seedling bowl. There is a valve under each feeding cup, and the opening and closing of the valve is controlled by a cam mechanism. It opens when the feeding cup turns to the top of the seedling guide tube, allowing the seedlings to fall, and then closes. Seedlings can be fed during the time period when the feeding cup is closed. Therefore, the time for artificial seedlings is prolonged, and the operation of feeding seedlings can be carried out in rapid succession. 60-70 seedlings can be thrown every minute. This is currently semi-automatic in the world. The frequency of transplanting seedlings by the transplanter is limited because the frequency of artificial seedlings is limited. For the rotary cup feeder, the limit is 70 plants/min. If the limit is exceeded, the operator will feel nervous and the phenomenon of missed planting will occur.
After the seedlings descend from the guide tube, they pass through the channel formed by the seedling fence and fall into the seedling ditch opened by the opener. With the support of the seedling fence, the seedlings will not fall in any direction. In an upright state, while the opener moves forward, the soil returning from the tail of the opener first covers the roots of the seedlings with soil to form an overburden. At this time, the seedling fence is also buried in the soil. While moving forward, the V-shaped suppression wheel pushes down the soil on the ditch wall to form a second overburden and compacts the soil. At this time, the seedling support bars move upward relative to the seedlings while continuing to support them. The role of seedlings is to prevent the seedlings from being overwhelmed or buried by the soil during the compaction process. With the forward movement of the Corn Sheller, the seedling support bar gradually separates from the seedlings, completing the task of supporting the seedlings, and the planting process of the seedlings also ends. As a result of the grid-type seedling supporter, the erection of the planted seedlings and the stability of the planting quality are greatly improved.
