The two rotating rods 61 are rotatably mounted on the mounting plate 12 through short shafts. The transmission shaft 21 is connected to the driving shaft 60 through a chain transmission, and the driving shaft 60 and the short shafts of the two rotating rods 61 are connected through a chain transmission. The front end of the swing rod 62 is rotatably connected to the front end of one of the rotating rods 61, and the front end of the other rotating rod 61 is hinged to one end of the connecting rod 63, and the other end of the connecting rod 63 is rotatably connected to the middle part of the swing rod 62. The duckbill seedling placing bucket 64 is installed at the end of the swing rod 62; the driving shaft 60 and the transmission shaft 21 and the rotating shaft 3 are driven by a chain to ensure synchronization and matching of the actions. When the driving shaft 60 rotates, the two rotating rods 61 rotate, driving the swing rod 62 to rotate in the vertical plane.

[0028] The seedling lowering device 7 includes a seedling storage tray 71 and a seedling lowering conduit 72. The seedling storage tray 71 is mounted on the frame 1, and the seedling lowering conduit 72 is mounted on the frame 1. The seedling lowering conduit 72 is docked at the bottom of the seedling storage tray 71. When the swing rod 62 swings to the highest position, the duckbill seedling placing bucket 64 is docked to the bottom of the seedling lowering conduit 72. The seedling storage tray 71 is connected to the short shaft of one of the rotating rods 61 through a chain. A first force arm 73 is hinged on the mounting plate 12, and a cam 74 is installed on the short shaft of the rotating rod 61. The first force arm 73 is connected to the cam 74. The transmission is triggered, and the end of the first force arm 73 is connected to the duckbill seedling placing bucket 64 through a steel rope soft pull line. When the swing arm 62 swings to the highest position, the duckbill seedling placing bucket 64 docks with the bottom end of the lower seedling tube 72.

The employee sitting on the worker's chair 14 arranges the tobacco seedlings on the tobacco seedling stacking platform 13 and places them one by one in the seedling storage tube 76. The tobacco seedlings in the seedling storage tube 76 remain stable under the support of the support guide rod 77 and rotate with the rotation of the seedling storage tube 76. When the tobacco seedlings run above the lower seedling guide tube 72, the corresponding tobacco seedling bottom loses the support of the support guide rod 77, and the tobacco seedlings enter the duckbill seedling placing bucket 64 through the lower seedling guide tube 72.

[0031] The front end of the connecting arm 2 is hinged on the frame 1, the rotating shaft 3 is installed at the end of the connecting arm 2, a second lever arm 22 is fixed on the connecting arm 2, and a telescopic device is hinged on the top of the second lever arm 22. The other end of the telescopic device is hinged on the frame 1. By adjusting the length of the telescopic device, the connecting arm 2 can be adjusted to swing up and down, and the height of the rotating shaft 3 and the pond-digging device 4 can be adjusted, thereby realizing the adjustment of the pond-digging speed to meet the needs of tobacco seedling transplanting in different soil and terrain conditions.

[0032] The telescopic device includes a sleeve 23, a telescopic rod 24, and a threaded rod 25. The middle part of the sleeve 23 is hinged on the frame 1, and the threaded rod 25 is installed in the sleeve 23 through the axial limit of the bearing. The telescopic rod 24 can be telescopically inserted in the sleeve 23. The telescopic rod 24 is threadedly connected to the threaded rod 25. The end of the telescopic rod 24 is hinged to the top of the second force arm 22. The front end of the threaded rod 25 is provided with a crank for facilitating force adjustment. The telescopic rod 24 can be extended and retracted by rotating the threaded rod 25 by the crank. The structure is simple and the adjustment is convenient and quick.

[0033] The pond digging device 4 is provided with a plurality of pond digging shovels 41 evenly installed along the circumference according to the required pond digging spacing.

[0034] The front end of the frame 1 is equipped with a support wheel 15 for support when idle. When idle, the frame 1 is disconnected from the traction of the tractor. At this time, it is supported on the ground by the support wheel 15, avoiding the problem of the pond-making device 4 and the ridging plow 5 contacting the ground, which can effectively prevent the pond-making device 4 and the ridging plow 5 from rusting.

[0035] A gate valve is installed on the feeding hose of the fertilizing device 8, and the end of the first lever 73 is connected to the gate valve through a steel rope soft pull line.

[0036] A valve is installed on the water outlet pipe of the watering device 9, and the end of the first lever 73 is connected to the valve through a steel rope soft pull line.

[0037] The feeding hose of the fertilizing device 8 and the water outlet pipe of the watering device 9 are both equipped with solenoid valves, which are connected to the PLC controller. The controller is installed on the frame 1, and an angle sensor is installed on the short axis of one of the rotating rods 61, which is connected to the PLC controller.

[0038] Working process: The present invention provides power through tractor traction, and ridges are formed by the ridging plow 5. During the tractor traction movement, the pond-making device 4 completes the pond-making work along the ridge; the driving shaft 60 is transmitted to the transmission shaft 21 and the rotating shaft 3 through a chain to ensure synchronization and matching of the actions. When the driving shaft 60 rotates, the two rotating rods 61 rotate, driving the swing rod 62 to rotate in the vertical plane; when the swing rod 62 swings to the highest position, the duckbill seedling placing bucket 64 is docked with the bottom end of the lower seedling guide tube 72. At this time, a tobacco seedling in the seedling storage tray 71 passes through the lower seedling guide tube 72 and enters the duckbill seedling placing bucket 64. When the swing rod 62 swings to the lowest position, the duckbill seedling placing bucket 64 is just in the tobacco pond. At this time, the cam 74 pushes the first force arm 73, and the first force arm 73 pulls the steel rope soft pull line, and the duckbill seedling placing bucket 64 opens to realize the placement of the tobacco seedlings; while the tobacco seedlings are being placed, the fertilizing device 8 and the watering device 9 complete the fertilizing and watering work.

[0039] The turntable 75 is connected to the short shaft of one of the rotating rods 61 to ensure that the seedling lowering speed is consistent with the movement cycle of the duckbill seedling releasing bucket 64. The employee sitting on the worker's chair 14 arranges the tobacco seedlings on the tobacco seedling stacking platform 13 and places them one by one in the seedling storage tube 76. The tobacco seedlings in the seedling storage tube 76 remain stable under the support of the support guide rod 77 and rotate with the rotation of the seedling storage tube 76. When the tobacco seedlings run above the seedling lowering guide tube 72, the corresponding tobacco seedling bottom loses the support of the support guide rod 77, and the tobacco seedlings enter the duckbill seedling releasing bucket 64 through the seedling lowering guide tube 72.

[0040] When idle, the frame 1 is disconnected from the tractor and is supported on the ground by the support wheels 15, avoiding the problem of the pond-making device 4 and the ridging plow 5 contacting the ground, which can effectively prevent the pond-making device 4 and the ridging plow 5 from rusting.

[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
