When the tray is conveyed, the driving cylinder contracts, each conical block moves upwards in a power shaft, all clamped crescent plates are loosened, the sliding frame loses balance, each tray lifting and overturning conveying mechanism gradually falls under the action of gravity, all conical blocks are located above the corresponding unfolding plates at the moment, the distance between every two combined supporting plates is the shortest, and meanwhile, under the huge elasticity of the compression spring, all tray rack side fixing pieces mutually contract, and all falling tray conveying frames are just clamped on the tray rack side fixing pieces on two sides below. Then the overturning cylinder of the lowest layer of plug tray lifting overturning conveying mechanism acts to overturn and incline the layer of plug tray lifting overturning conveying mechanism, and the layer of greenhouse plug tray seedlings are conveyed to the plug tray switching mechanism under the action of the power roller conveyor. After the hole tray conveying work of the lowest layer is finished, the driving cylinder extends downwards, the power shaft of each conical block moves downwards to enable each conical block to gradually move downwards and be positioned below the corresponding opening plate, the distance between every two combined supporting plates is farthest, the hole tray frame side fixing pieces overcome the elasticity of the compression springs and are far away from each other, each layer of hole tray lifting and overturning conveying mechanism is not clamped on the hole tray frame side fixing pieces any more and starts to continuously fall, the hole tray lifting and overturning conveying mechanism of the lowest layer directly falls on the hole tray conveying frame resetting mechanism, and the pressing shaft presses on the crescent moon plate again at the moment, make the remaining three-layer cave dish of upside go up and down to overturn conveying mechanism and fall to the crescent moon board of below on, the crescent moon board is by the chucking, and the upset cylinder action among the cave dish lift upset conveying mechanism of lower floor to carry the cave dish switching mechanism with second dish greenhouse cave dish seedling on. The above actions are repeated, and the purposes of downward movement layer by layer and sequential conveying of plug seedlings among the plug lifting, overturning and conveying mechanisms can be achieved.

The lifting cylinder is vertically fixed on the mounting frame to drive the unpowered roller conveyor to swing; the limiting plate is rotatably positioned at the outlet end of the unpowered roller conveyor and is used for buffering the plug tray; the driving motor is fixed on the mounting frame, and an output shaft of the driving motor is fixedly connected with the limiting plate so as to drive the limiting plate to turn over; the push cylinder is horizontally arranged, the cylinder body of the push cylinder is fixed on the rack, and the push rod of the push cylinder is fixedly connected with the mounting rack. During operation, the unpowered roller conveyor receives the plug tray, the lifting cylinder drives the unpowered roller conveyor to swing for a proper angle and then to incline, the plug tray is conveyed to the limiting plate to be buffered under the action of gravity, then the driving motor acts to drive the limiting plate to overturn, so that the plug tray slides out from an outlet of the unpowered roller conveyor to an external conveyor belt (not shown in the figure), and the automatic plug tray placing operation is completed.
As shown in fig. 7, the tray conveying frame resetting mechanism is installed on the frame and located right below each tray lifting and overturning conveying mechanism, so as to reset the position of each tray lifting and overturning conveying mechanism and ensure continuous tray placing operation of the device.
