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.
Description
Technical field
The present invention relates to a kind of crusher rotor speed measuring device, belong to disintegrating machine control technology field.
Background technology
Rotor for disintegrating machine in prior art tests the speed, the general conventional speed measuring device of installation that passes through realizes carrying out, but crusher rotor tests the speed comparatively specifically, during its work, vibration amplitude is comparatively large, ash is large, vibration amplitude means that greatly the conventional speed measuring device effect that tests the speed is seriously influenced, and ash then has a strong impact on greatly the service life of this speed measuring device.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of crusher rotor speed measuring device, this crusher rotor speed measuring device, by the setting of infrared facility, effectively ensure that the effect that tests the speed can not receive significantly vibration influence when disintegrating machine works.
The present invention is achieved by the following technical programs.
A kind of crusher rotor speed measuring device provided by the invention, comprises rotor axis, rotor, housing, infrared facility, reflective mirror; Described rotor is fixed on rotor axis, and rotor side surface is fixed with reflective mirror, on housing respective rotor axis and rotor place one side on be fixed with infrared facility; Described infrared facility is infrared launcher and infrared receiving device, and infrared launcher and infrared receiving device are all just to reflective mirror, and the infrared light that infrared launcher sends can be received by infrared receiving device through mirror reflection.
In described infrared facility, infrared launcher towards with infrared receiving device be less than 15 ° towards angle.
Also comprise ash disposal part, ash disposal part is fixed on housing, is positioned at the lateral location of infrared facility.
Described ash disposal part position, on the camber line formed with rotor turns corresponding to reflective mirror.
Described ash disposal part is fixed by fixture, and ash disposal part and reflective mirror overlap in side projection.
Described ash disposal part is hairbrush or sponge.
Beneficial effect of the present invention is: 1. arranging of infrared facility effectively ensure that the effect that tests the speed can not receive significantly vibration influence when disintegrating machine works; 2. arranging of ash disposal part effectively ensure that the effect that tests the speed can not be subject to the large impact of ash, and service life is secure.

Detailed description of the invention
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A kind of crusher rotor speed measuring device as shown in Figure 1 to Figure 3, comprises rotor axis 11, rotor 12, housing 13, infrared facility 21, reflective mirror 22; Described rotor 12 is fixed on rotor axis 11, and rotor 12 side is fixed with reflective mirror 22, on housing 13 respective rotor axis 11 and rotor 12 place one side on be fixed with infrared facility 21; Described infrared facility 21 is infrared launcher and infrared receiving device, and infrared launcher and infrared receiving device are all just to reflective mirror 22, and the infrared light that infrared launcher sends can be received by infrared receiving device through reflective mirror 22 reflection.
Thus, by reflective mirror 22 in rotor 12 rotation process, ultrared interruption is reflected, thus binding time very simple computation can go out the rotating speed of rotor 12.
Further, in order to ensure better signal launch, reception, light reflection angle should be not excessive, therefore in described infrared facility 21, infrared launcher towards with infrared receiving device be less than 15 ° towards angle.
For ensureing the lasting good effect that tests the speed, avoid ash to shelter from greatly reflective mirror 22 and cause Signal reception failure, therefore also comprise ash disposal part 23, ash disposal part 23 is fixed on housing 13, is positioned at the lateral location of infrared facility 21.
Specifically, described ash disposal part 23 position, is corresponding on the camber line of reflective mirror 22 with rotor 12 rotation formation.
Further, for cost-saving, described ash disposal part 23 is fixed by fixture 24, and ash disposal part 23 and reflective mirror 22 overlap in side projection.
As most preferably scheme, described ash disposal part 23 is hairbrush or sponge.
