Multilayer movable type conveyer of growing seedlings, its characterized in that: the seedling raising tray conveying device comprises a conveying support with a multilayer structure, wherein conveying mechanisms used for conveying seedling raising trays are arranged on each layer of the conveying support, one side of each layer of the conveying mechanism is provided with a one-way rotating mechanism used for conveying the seedling raising trays and relieving the sliding speed of the seedling raising trays, the one-way rotating mechanisms correspondingly connected with the adjacent conveying mechanisms are distributed on the left side and the right side of the conveying mechanism, so that the one-way rotating mechanisms on the same side of the conveying mechanisms are distributed at intervals in the vertical direction, and each layer of the conveying mechanism is in transmission connection with a driving mechanism, so that the conveying mechanisms on the even layers are opposite to the conveying mechanisms on the odd layers in operation direction, and the seedling raising trays are in S-shaped one-way circular motion from top to bottom on the conveying mechanisms.

2. The multi-layer mobile seedling conveyor of claim 1, wherein: one end of the unidirectional rotating mechanism is rotatably connected to the conveying support, and the other end of the unidirectional rotating mechanism can rotate downwards in a unidirectional mode and is abutted against the conveying mechanism on the next layer.

3. The multi-layer mobile seedling conveyor as claimed in claim 2, wherein: the unidirectional rotating mechanism comprises a rotating support piece, a rotating pushing piece and a buffer piece, wherein the fixed end of the rotating support piece is rotatably connected to the conveying support, the moving end of the rotating support piece can rotate relative to the fixed end, the rotating pushing piece for pushing the moving end of the rotating support piece to rotate is mounted on the rotating support piece, and the buffer piece is fixedly mounted at the moving end of the rotating support piece.

4. The multi-layer mobile seedling conveyor as claimed in claim 3, wherein: the rotary supporting piece comprises a rectangular frame, one end of the rectangular frame is rotatably connected with the conveying support through an L-shaped tail support, the width of the rectangular frame is consistent with that of the conveying mechanism, a plurality of movable rolling shafts are rotatably connected in the rectangular frame, and the movable rolling shafts are arranged in parallel along the width direction of the rectangular frame.

5. The multi-layer mobile seedling conveyor as claimed in claim 4, wherein: the movable rolling shaft is connected with a rectangular frame bearing, and the circumferential diameter of the movable rolling shaft is larger than the thickness of the rectangular frame.

6. The multi-layer mobile seedling conveyor as claimed in claim 3, wherein: the rotary pushing part comprises an electric push rod, the fixed end of the electric push rod is arranged on the corresponding conveying support below the rectangular frame, and the pushing end of the electric push rod is fixedly connected with the rotary supporting part.

7. The multi-layer mobile seedling conveyor as claimed in claim 3, wherein: one end of the buffer piece is fixedly installed at the lower end of the rectangular frame, the other end of the buffer piece is bent upwards to be parallel to the upper end of the movable rolling shaft, and the bent height of the buffer piece is larger than the thickness of the conveying mechanism.

8. The multi-layer mobile seedling conveyor as claimed in claim 7, wherein: when the rectangular frame abuts against the next layer of conveying mechanism, the buffer piece is inserted into the gap of the conveying mechanism.
