[0002] The fruit and vegetable seedling machine is an agricultural mechanical equipment for seedling of vegetables and fruits. A suitable model is selected according to the seedling demand and planting scale. A small-scale seedling machine is selected for small-scale seedling. A large-scale seedling machine with high automation is selected for large-scale seedling. If precise seeding function is needed, a seedling machine with air suction or needle suction seeding device is selected. If the seedling environment control is emphasized, a seedling machine with perfect temperature control, illumination and irrigation system is selected. A reliable and good reputation brand is selected. The product user evaluation and after-sales service can be checked to ensure the stability and durability of the seedling machine.

The quantitative water feeding mechanism feeds water into the stirring box in a quantitative manner. The substrate stirring mechanism stirs different types and humidity requirements of the substrate uniformly in the shortest time. The plug tray conveying mechanism drives the plug tray to move at a uniform speed. The auxiliary uniform discharging mechanism allows the substrate to fall uniformly into the plug tray. The height-adjustable substrate scraping mechanism scrapes the excess substrate on the plug tray of different heights. The control box controls the state of each electric appliance. The substrate stirring, discharging, tray loading and scraping processes are completed in an orderly manner through the cooperation of all components.
