The push pin on the connecting plate 24 pushes the fork 36 to rotate when the duckbill goes down, and the fork 36 pulls the seedling cup 35 to open the movable cup piece, and the seedling falls into the seedling guide cylinder. When the duckbill is lifted, the push piece 38 is separated from the fork 36, the movable cup piece is closed under the action of gravity and the return spring, and the single seedling placing is completed. The seedling after planting is backfilled to the planting hole by the conical wheel 44 at the rear of the frame 1, and the soil surface is compacted by the flat wheel 45, so that the root system of the seedling is in close contact with the soil. When adjusting the plant spacing, the first top wire is loosened, the fixed plate 17 is slid left and right along the first guide pipe 18, the horizontal spacing of the planting mechanisms on both sides is adjusted, and then the top wire is locked, so that the different plant spacing requirements are met. The mounting frame 42 is slid along the fourth guide pipe 41, the spacing between the conical wheel 44 and the flattening wheel is adjusted, and different ridge widths are matched.

[0035] The novel rotary tillage type transplanting machine realizes synchronous operation of rotary tillage, walking, planting, seedling placing and soil covering through power distribution of the engine 3, and greatly improves the operation efficiency. The cam 21 drives the duckbill to move up and down, and the opening and closing piece is controlled to open and close accurately through the pull wire rod 29, the duckbill opening and closing is synchronous with the seedling placing action, and the seedling missing rate is low. The top pushing piece 38 on the connecting plate 24 triggers the seedling cup 35 to open and close, and ensures that the seedling placing time is completely matched with the duckbill downward inserting action. The sliding fixing plate 17 adjusts the lateral spacing of the planting mechanism, and the stability is high after the top pin is locked. The rotary tillage cutter 6 is adjustable in tillage depth, and the soil covering wheel spacing is adjustable, and the operation requirements of various soils such as clay and sandy soil are met.
