The operations such as the louver portion easy access of portion's groove.Groove is provided with the middle of the body of plate 2 in addition, the detachable card on the groove
Equipped with sensor cluster 10, the sensor cluster 10 includes the shell 9 of nylon material, and permanent magnet 5 is provided with the shell 9,
The permanent magnet 5 is connected with one end of magnetic conductive rod 6, and the other end of the magnetic conductive rod 6 is connected with Hall element 7, the Hall element 7
Output end is connected with the binding post on shell 9.Above-mentioned magnetic conductive rod 6 is using existing conventional permeability magnetic material such as electrical pure iron DT3
Preparation.
Signal conditioning circuit wherein is also equipped with shell 9, input and the Hall element 7 of the signal conditioning circuit
Output end is connected, so that by the output signal of Hall element 7 by amplification, isolation so as to which the normalized current for being converted to 4-20mA is believed
Number, and the output end of the signal conditioning circuit is connected with the binding post on shell 9.
Embodiment 1：
A kind of chain rupture monitoring device of drag conveyor, including permanent magnet 5, Hall element 7, magnetic conductive rod 6, signal condition electricity
Road plate 8, sensor nylon outer shell 9.Specifically permanent magnet 5, Hall element 7, magnetic conductive rod 6, signal conditioning circuit plate 8 are encapsulated in
Signal acquisition module is constituted in sensor nylon outer shell 9, it is processing profiled on the plate 2 of drag conveyor intermediate section groove for opening clearstory 1
In groove or rectangular recess, the special-shaped slot that packaged sensor is fixed on to plate 2, the signal acquisition module is conveyed with scraper plate
The PLC connection of machine.
Hall element 7 is a kind of Magnetic Sensor based on Hall effect, can detect magnetic field and its change.Hall element 7
Have many advantages, their sound construction, small volume is lightweight, long lifespan is easy for installation, small power consumption, frequency is high, shatter-proof
It is dynamic, it is not afraid of the pollution or corrosion of dust, greasy dirt, steam and salt fog etc..The utility model scrapper conveyor intermediate section groove for opening clearstory 1, insert
Plate 2 constructs a magnetic field, when scraper chain 4 is by the magnetic field, can influence the distribution in magnetic field, therefore pass through the magnetic flux of Hall element 7
The size of amount can change, and show as the change of the voltage swing of inductive output, can so monitor whether chain or scrape
Plate 3 passes through.
Chain rupture monitoring device of the present utility model is arranged in the plate 2 of drag conveyor intermediate section groove for opening clearstory 1, by sensing
