Abstract: A vegetable transplanting device includes a robotic arm, a positioning ring fixedly disposed on an outside of the robotic arm, and a transplant assembly connected to the robotic arm. The transplant assembly includes: a motor fixedly disposed at an end of the robotic arm; a fixing frame fixedly mounted on a side surface of the positioning ring away from the robotic arm; a worm screw fixedly disposed at an output end of the motor; first fixing rods fixedly disposed and passing through the fixing frame; worm gears, each rotatably installed on an outside of one of the first fixing rods, the worm gears being engaged with the worm screw by teeth; connecting rod assemblies, each rotatably installed on the outside of at least one of the first fixing rods; and clamping members, each rotatably connected to one end of the corresponding connecting rod assembly away from the fixing frame.
