Description
Technical field
It the utility model is related to a kind of coal bunker buffer unit.
Background technology
My unit coal bunker have four coal bunkers --- 1#, 2#, 3#, 4# coal bunker.The belt feeder model transported to coal bunker
For STJ-1000, belt speed 2m/s.Coal does parabolic motion when flowing through belt-conveying to coal bunker, movement locus is after hitting bulkhead
Reach orlop.Therefore bulkhead is impacted and destroyed by coal stream at first, it is often necessary to which bulkhead is repaired.
Utility model content
The technical problems to be solved in the utility model is how to overcome the drawbacks described above of prior art, there is provided a kind of coal bunker delays
Flushing device.
In order to solve the above technical problems, this coal bunker buffer unit includes N bars buffer chain, horizontal fix bar and sound and light alarm dress
Put, be uniformly placed with N number of manhole in the horizontal fix bar, the acoustic-optic alarm include open type gravity switch,
Alarm lamp and buzzer, the open type gravity switch include movable contact and stationary contact, the movable contact have it is N number of, it is each dynamic to touch
The connected core bar in point lower section and a spring, the core bar lower end pass through manhole and buffer chain phase in horizontal fix bar
Even, the lower end of the spring is fixed in the horizontal fix bar, and the stationary contact also has N number of, is arranged on above movable contact, and
N number of stationary contact corresponds with N number of movable contact, is to connect between the stationary contact, between movable contact, the stationary contact, report
Warning lamp, buzzer and adapted power supply with movable contact after wired in series by being connected to form alarm circuit.
It is so designed that, after coal stream projects from unloading roller, when falling on 1/3 position of buffer chain top, coal stream is run rail
Mark changes, and the movement of falling object is changed to by original parabolic motion, so that the direct impacting house bottom in coal stream portion, is played to bulkhead
Protective effect.Round-link chain can freely swing, and avoid rigid snubber.Once there is buffering even to drop, acted in the elastic force of spring
Under, movable contact moves up, and is contacted with stationary contact and connects warning circuit, starts sound and light alarm.
As optimization, the buffer chain is round-link chain.It is so designed that, buffer chain is formed using the round-link chains of 30 ※ of φ 108, is protected
The durability of structure is demonstrate,proved.
As optimization, the bottom of every buffer chain is additionally provided with a weight.It is so designed that, adds buffer chain
Weight, buffering effect are more preferable.
As optimization, a controlling switch is additionally provided with the alarm circuit.
The utility model coal bunker buffer unit rapidoprint has reached the effect that past heritage utilize using the superseded round-link chain of recovery
Fruit, after the buffer unit, coal stream impact bulkhead phenomenon is prevented, has reduced coal bunker and repair number, reduce human and material resources
Input, have good economic benefit, be widely used in coal bunker, ore storage bin etc. protection during.
Brief description of the drawings
The utility model coal bunker buffer unit is described further below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the embodiment one of this coal bunker buffer unit；
In figure：1 be buffer chain, 2 be horizontal fix bar, 3 be manhole, 4 be open type gravity switch, 41 be touch

Switch 4, alarm lamp 5 and buzzer 6, the open type gravity switch 4 include movable contact 41 and stationary contact 42, the movable contact 41
Have N number of, the lower section of each movable contact 41 is connected a core bar 7 and a spring 8, and the lower end of core bar 7 is through in horizontal fix bar 2
Manhole 3 is connected with buffer chain 1, and the lower end of the spring 8 is fixed in the horizontal fix bar 2, the stationary contact 42
Have N number of, be arranged on the top of movable contact 41, and N number of stationary contact 42 corresponds with N number of movable contact 41, between the stationary contact 42,
It is series connection between movable contact 41, after the stationary contact 42, alarm lamp 5, buzzer 6 are connected with adapted power supply 9 by wire 10
Alarm circuit is connected to form with movable contact 41.The buffer chain 1 is round-link chain.The bottom of every buffer chain 1 is also set
There is a weight 11.A controlling switch 12 is additionally provided with the alarm circuit.
