According to the infrared-based crusher speed measurement apparatus of the present invention, the arrangement of the reflective mirror, the infrared emitting head and the infrared receiving head can effectively ensure that a speed measurement effect is not influenced by great shock of a crusher during operation; arrangement of a solenoid apparatus and an ash removing member can effectively ensure that the speed measurement effect is not influenced by severe ash; in addition, a service life can be ensured.
Description
Technical field
The present invention relates to a kind of based on infrared disintegrating machine 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 serviceable 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 based on infrared disintegrating machine speed measuring device, based on the setting of infrared disintegrating machine speed measuring device by reflex reflector lens, infrared emission head and infrared receiving terminal, should 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.
Provided by the invention a kind of based on infrared disintegrating machine speed measuring device, comprise rotor axis, rotor, housing, reflex reflector lens, infrared emission head, infrared receiving terminal; Described rotor is fixed on rotor axis, and the position on rotor axis in the middle of two rotors is fixed with reflex reflector lens; On described housing corresponding reflex reflector lens place one side on be fixed with infrared emission head and infrared receiving terminal, the central point towards place straight line intersection in reflex reflector lens towards place straight line and infrared receiving terminal of infrared emission head.
Described infrared emission head be less than 15 ° towards place straight line and infrared receiving terminal towards angle between the straight line of place.
Also comprise electromagnetic spool device, ash disposal part, power supply; Have coil in electromagnetic spool device, coil circuit is connected to power supply; Electromagnetic spool device and power supply are separately fixed at the both sides of described reflex reflector lens, and electromagnetic spool device at one end arranges ash disposal part in reflex reflector lens.
Described ash disposal part is hairbrush or sponge.
The device of timing reversion output electrode is provided with in described power supply.
Beneficial effect of the present invention is: 1. arranging of reflex reflector lens, infrared emission head and infrared receiving terminal effectively ensure that the effect that tests the speed can not receive significantly vibration influence when disintegrating machine works; 2. electromagnetic spool device and 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 serviceable life is secure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the side view of Fig. 1 rotor;
Fig. 3 is the vertical view of Fig. 1, for representing clear, has a rotor not show;
In figure: 11-rotor axis, 12-rotor, 13-housing, 21-reflex reflector lens, 22-infrared emission head, 23-infrared receiving terminal, 31-electromagnetic spool device, 32-ash disposal part, 33-power supply.
Embodiment
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
As shown in Figure 1 to Figure 3 a kind of based on infrared disintegrating machine speed measuring device, comprises rotor axis 11, rotor 12, housing 13, reflex reflector lens 21, infrared emission head 22, infrared receiving terminal 23; Described rotor 12 is fixed on rotor axis 11, and the position on rotor axis 11 in the middle of two rotors 12 is fixed with reflex reflector lens 21; On described housing 13 corresponding reflex reflector lens 21 place one side on be fixed with infrared emission head 22 and infrared receiving terminal 23, the central point towards place straight line intersection in reflex reflector lens 21 towards place straight line and infrared receiving terminal 23 of infrared emission head 22.
Thus, by reflective mirror 21 pairs of infrared emission heads 22 in rotor 12 rotation process send out ultrared to be interrupted reflection, infrared receiving terminal 23 discontinuous reception to infrared signal, thus binding time very simple computation can go out the rotating speed of rotor 12.
Further, in order to ensure that better signal is launched, reception, light reflection angle should be not excessive, therefore described infrared emission head 22 be less than 15 ° towards place straight line and infrared receiving terminal 23 towards angle between the straight line of place.
For ensureing the lasting good effect that tests the speed, avoiding ash to shelter from greatly reflective mirror 21 and causing Signal reception failure, also comprising electromagnetic spool device 31, ash disposal part 32, power supply 33; Have coil in electromagnetic spool device 31, coil circuit is connected to power supply 33; Electromagnetic spool device 31 and power supply 33 are separately fixed at the both sides of described reflex reflector lens 21, and electromagnetic spool device 31 at one end arranges ash disposal part 32 in reflex reflector lens 21.
As most preferably scheme, described ash disposal part 32 is hairbrush or sponge.
Obviously, as ensureing that ash disposal part 32 realizes the most cost-saving mode of reciprocating movement ash disposal, in described power supply 33, be provided with the device of timing reversion output electrode, thus realize the reciprocal control of electromagnetic spool device 31 pairs of ash disposal parts 32 motions by reversion electrode.
