Open the self-moving door 115, which tightly fits the tray holder 112 and the opening 114, allowing the seedling filling tray to fall onto the telescopic rod 121. Then, the seedling filling tray passes through the tray delivery port 101 and smoothly falls onto the tray placement port 200 along the tray delivery guide tube 122. Finally, the seedling filling tray smoothly falls onto the conveyor belt 122 along the buffer plate 26. Control the motor to start the conveyor belt 31 via the control console 7. Use the position sensor to know the position of the seedling filling tray. When the seedling filling tray is conveyed directly below the funnel, pour the substrate into the funnel 202 and let it fall into the seedling filling tray through the feed port 201 to fill the seedling filling tray with substrate. The operation is convenient and the work efficiency is fast. The seedling filling tray is driven to the scraper 42, which smooths the substrate on the seedling filling tray. Finally, the substrate falling onto the conveyor belt 31 falls into the substrate collection box 5 for collection, which ensures the ground environment and makes cleaning and collection more convenient, which is beneficial to practical use.
