[0026] Wherein, since the first motor 111, the second motor 121 and the electric push rod 21 are all electrically connected with the controller 3, so that the controller 3 can directly drive the first motor 111, the second motor 121 and the electric push rod 21 to operate, which greatly improves the intelligence of the production device for extracting rare earth oxides from neodymium iron boron waste.
