Background technology
At present, a kind of device for sensing longitudinal leakage of conveying belt, China Patent Publication No.: CN2223735, this sensor is fixedly installed on the easiest detector of tearing the below, position of load-transfer device, it is the inverting amplifier of an open loop, when two probe is aimed at respectively half center of the 8-shaped back traverse coil be embedded in the load-transfer device, just form an oscillator, the oscillator signal of generation produces the Fixed width pulse output signals through translation circuit.
The second is for tearing switch, and this tears the switch mounted in pairs in the both sides of belt, is coupled together by the aircraft cable of two sections ethene overcoats.One end of rope is permanently affixed on the Support bracket, and the other end is connected to and tears apart on the spring ball of shutting.Two sections cotton ropes have formed a C/LOOP consistent with the belt grooved below belt.Hang when the belt that has object to expose or tear hangs, when sweeping one or two steel cables, spring ball is drawn out base, causes that two micro-switchs send to report to the police or turn off conveyer.
The third sensor is that GVY type sensor belongs to piezoresistive, coal breakage is pressed onto on the sensor when namely utilizing longitudinal rupture of adhesive tape or cross break, after coal breakage weight on 12.4 * 12.4cm2 unit area reached more than 2 * 105 milligrams, the resistance between sensor two mouths was less than or equal to 2 kilo-ohms by changing into greater than 1 megaohm.Survey existing of longitudinal rupture of adhesive tape or cross break with the variation of sensor output impedance, and the variation of sensor impedance is sent to associate device, realize sealing-tape machine longitudinal tear or broken belt protector.
More than three kinds of existing sensors of tearing all in actual production, to use for a long time, also can realize the belt protecting longitudinal rupture, but existent defects all, 1. number tear sensor do not using because troublesome maintenance is existing; 2. number tear sensor and be fit to detect hard thing and penetrate belt but do not form large-area tearing, detect that to tear this kind detection effect ideal this moment, but because machine attention is cumbersome, the existing use seldom; 3. number tear the existing colliery of sensor and use at most, effect is more satisfactory, but because the bad sensor conductive rubber of waterproof effect is aging easily, produces to such an extent as to produce the misoperation impact.
The utility model content
The purpose of this utility model is that a kind of infrared type conveyer band discerption sensor will be provided, and solution has now and tears the sensor maintenance trouble, waterproof effect is bad, and the sensor conductive rubber is aging easily, easily produces the problem of misoperation impact production.
The purpose of this utility model is achieved in that this tears sensor and comprise: infrared transmitter, infrared remote receiver, adjustable support, dust guard and fixed support; Respectively connect a fixed support in belt feeder support body two inboards, fixed support is between up belt roller and descending belt; Two support bracket fastened upper ends all are connected with dust guard; Be connected with respectively adjustable support in support bracket fastened side, on two adjustable supports, be connected with respectively infrared transmitter and infrared remote receiver, infrared transmitter is corresponding with infrared remote receiver.
Described infrared transmitter comprises: stabilivolt, oscillator, infrared light generating chip, indicating circuit, aerotron and infraluminescence pipe; Stabilivolt is to the infrared transmitter power supply, and oscillator is connected with the input end of infrared light generating chip, and the mouth of infrared light generating chip is connected with indicating circuit, and the mouth of infrared light generating chip is connected with the infraluminescence pipe by aerotron simultaneously.
Described infrared remote receiver comprises: infrared receiving tube, voltage conversion circuit, voltage stabilizer, bleeder circuit, comparator circuit and control output circuit; Infrared receiving tube is connected with the input end of comparator circuit by voltage conversion circuit; Voltage stabilizer is connected with the input end of comparator circuit by bleeder circuit; The mouth of comparator circuit is connected with the control output circuit.
Beneficial effect: owing to adopted such scheme, infrared type is torn sensor and is comprised of infrared transmitter, infrared remote receiver and fixed support, infrared transmitter and infrared remote receiver are over against arrangement, the infrared transmitter emission is similar to the infrared light of straight line after the energising, during the belt feeder normal operation, do not have shelter between infrared transmitter and infrared remote receiver, infrared remote receiver can normally receive the infrared light that infrared transmitter sends, and is failure to actuate in receptor inside; When belt tearing occured, the coal on the belt dropped on the support, shelters from the infrared ray that infrared transmitter sends, and receptor does not receive the infrared light that infrared transmitter sends, and infrared remote receiver sends action command, and belt feeder is implemented protection.Solved and existing torn the sensor maintenance trouble, waterproof effect is bad, the sensor conductive rubber is aging easily, easily produces the problem that the misoperation impact is produced, and has reached the purpose of this utility model.
Advantage: it is good that infrared type is torn the sensor water-proof moisture effect, and safety performance is high, and antijamming capability is strong, is difficult for misoperation, and it is poor to have overcome conventional conductive rubber type sensor sealing effectiveness, and conductive rubber easily wears out, the shortcoming of oxidation.
