A chain and clamp type transplanter power transmission system according to any one of claims 1 to 6, wherein the ground wheel is in contact with the ground during operation of the transplanter, and the power for rotation of the ground wheel is transmitted to the ground wheel input shaft through the ground wheel input sprocket and the ground wheel output sprocket and then to the ground wheel input gear, and the ground wheel input gear acts on the first output gear through the intermediate gear to drive the output shaft to rotate, thereby driving the whole transplanter to move;
The output shaft drives the seedling ejection driving sprocket to rotate, the seedling ejection driving sprocket drives the seedling ejection driven sprocket to rotate through a chain, and then the cam is driven to rotate, the cam rotates to push the ejector rod to move in the slideway, the pot seedlings are ejected forwards from the rear end of the seedling tray, seedling ejection is completed, and after seedling ejection is completed, the pot seedlings return under the action of the spring; the output shaft rotates for one circle, and the ejector rod pushes the seedling forward for one time;
The seedling disc driving sprocket and the seedling ejection driven sprocket mounted on the cam shaft rotate at equal angular speed, the seedling disc driving sprocket drives the seedling disc driven sprocket to rotate, the seedling disc driven sprocket drives the seedling disc intermediate shaft to rotate, the seedling disc intermediate shaft drives the sixth driving gear to rotate, the sixth driving gear drives the sixth driven gear, and the sixth driven gear drives the seedling disc driving gear to rotate; every 1 turn of the output shaft, the seedling tray drives the gear to rotate 1/6 turn;
The output shaft drives the chain clamp driving sprocket to rotate, the chain clamp driving sprocket drives the chain clamp driven sprocket to rotate, and then the chain clamp driving shaft is driven to rotate, the driving shaft drives the chain clamp sprocket to rotate, so that the chain clamp chain is driven to rotate, and then the seedling clamp is driven to rotate, the driving plate on the seedling clamp is contacted with the driving plate, the driving plate is driven to rotate, and then the seedling conveying belt is driven to move to convey a pot seedling to the seedling clamp, and then the automatic pot seedling supply of the chain clamp type transplanting machine is realized.
