Abstract
The invention provides a speed measurement device for a crusher rotor. The speed measurement device comprises a rotor center shaft, a rotor, a shell, infrared devices and a reflective mirror, wherein the rotor is fixed onto the rotor center shaft, the reflective mirror is fixed onto the side of the rotor, the infrared devices are fixed onto one surface, which corresponds to the rotor center shaft and the rotor, of the shell and comprise an infrared emission device and an infrared receiving device which are both just opposite to the reflective mirror, and infrared light emitted from the infrared emission device is reflected by the reflective mirror and then can be received by the infrared receiving device. With the infrared devices, the speed measurement effect cannot be affected by large-amplitude vibration of a crusher during working; with an ash removal element, the speed measurement effect cannot by affected by much ash, and the service life of the speed measurement device can be guaranteed.
