Once the seedlings are fully stored, continuous seedling feeding can begin. After continuous feeding begins, the seedling shaking device 2 is activated to loosen the seedlings 7, improving the uniformity of seedling distribution 7 in the clamping area each time, facilitating the operation of the clamping device 4. After the clamping device 4 clamps the seedling 7, the pushing device 3 pushes it out, and the seedling 7 is pushed into the seedling feeding device 5. Simultaneously, the clamping device 4 is released and falls to a clearance position. Then, the pushing device 3 begins to move towards its initial position. Before retracting to its initial position, the clamping device 4 quickly returns to its clamping area, and the pushing device 3 retracts to its initial position. The seedling 7 is then fed out by the seedling feeding device 5, completing one operation cycle (e.g., ...). Figure 8 (As shown). The seedling delivery device 5 consists of two sets of rollers that work continuously to ensure that the seedlings 7 are pushed over and delivered in a timely manner. The seedling shaking device 2, the seedling clamping device 4, and the seedling pushing device 3 reciprocate in motion. After completing one cycle, they continue to work sequentially. When the seedling pushing device 3 returns to its original position, the seedling shaking device 2 starts up again.
