[0062] The water supply device 37 can provide a continuous water source for the seedling transplanting machinery, greatly improving the working efficiency and transplanting quality of the seedling transplanting machinery, and improving the efficiency by more than 2 times;

[0063] Reduce labor and reduce costs. Traditional transplanting machinery either needs to replenish water manually after transplanting, or is equipped with a water tank. To replenish the water in the water tank, the transplanting machinery will continuously go back and forth with the water source to add water to the water tank to ensure water for transplanting. After using the automatic water supply and seedling transplanting machine, the transplanting machinery does not need to carry a heavy water tank, nor does it need to constantly go back and forth with the water source. It can provide a steady supply of water for the transplanting machinery, reduce labor and reduce costs, and improve work efficiency.

[0064] The water supply device can be a field water source pipeline, the inlet end of the water pipe is connected to one end of the field water source pipeline and fixed to the field, providing a continuous water source for the water pipe on the device; the connecting pipe 7 is rotatably arranged in the support cylinder 5 to ensure that the water outlet pipe remains stationary when the pipe winding roller 2 rotates continuously when the hose is retracted and released;

[0067] When the transplanting machine moves away from the field head, the water supply device is located far from the rear of the transplanting machine. When the transplanting machine moves toward the field head, the hose reel is in the action of retracting the hose, and the swing arm 10 can rotate around the hinge shaft 45 and be located near the front of the transplanting machine to ensure that the hose is not crushed by the transplanting machine when the transplanting machine moves toward the water source section at the field head.
