A tractor suspension type automatic transplanting machine for plug tray seedlings includes land wheels, a machine frame, a three-point linkage, a seedling pickup mechanism, a plug tray conveying device, a plug tray recovery device, seedling separating and planting devices driven by land wheels, and a watering device. Through front and rear drive cylinders, the seedling pickup mechanism is driven to move front and back to pick up seedlings above plug trays and release seedlings above a seedling guide device. Juxtaposed left and right seedling pickup modules in the seedling pickup mechanism are driven by left and right drive cylinders, to move left and right and pick up seedlings after combing, and to release seedlings after separating towards left and right. Plug trays fall onto a plug tray conveyor belt of the plug tray recovery device and slides into a plug-tray-recovery stacking box.

An ejecting-clamping-pulling combined seedling fetching device for an automatic transplanter and an operating method therefor. The device comprises: a seedling ejecting mechanism (), a seedling feeder mechanism (), a seedling fetching mechanism (), and a control system. The seedling feeder mechanism () is mounted on a stander; the seedling ejecting mechanism () is mounted on the seedling feeder mechanism () and is located at the rear side of the seedling feeder mechanism (); the seeding fetching mechanism () is mounted at the stander and is located at the front side of the seedling feeder mechanism (). An upper ejector rod support (-) and a lower ejector rod support (-) are provided on the seedling ejecting mechanism (); the seedling ejecting rods on the two supports are disposed in a staggered manner, and the upper ejector rod support (-) and the lower ejector rod support (-) are configured to alternately eject and loosen seedling trays. The ejecting-clamping-pulling combined seedling fetching device can eject and loose seedling trays, and the completeness of the trays is guaranteed. The ejecting-clamping-pulling seedling fetching method can accurately control seedling fetching and feeding actions; and furthermore, the device is simple in structure, high in reliability and efficiency and low in damage rate of tray bodies.
