Left side is connected with the suspension arrangement being suspended on roller rack 2, the right side connection tensiometer of the right carrying roller 4-1, the pulling force
The hook 5-1 connections on roller rack 2 are counted and be articulated in, the right carrying roller 4-1 are vacantly hung up, the right carrying roller 4-1, the left side
Carrying roller 4-2 and middle idler roller 3 form idler machining, hang on roller rack 2, the tensiometer electrically connects with controller 7.Due to support
Roller group side is hung on roller rack 2 by tensiometer, therefore the top of belt 9 that tensiometer can be measured on the idler machining is accumulated
The size of coal amount.
During using the technical scheme, the lower section ribbon conveyer that the device is installed on to two strip-type conveyer lap-joints connects
At coal.When two strip-type conveyer normal operations, the ribbon conveyer of top throws coal to the ribbon conveyer of lower section, under
The belt 9 of ribbon conveyer is run forward, at the Coal Transport being connected to downstream.Now according to the belt of the present embodiment
Coal coal amount above the anti-coal piling early warning protector of conveyer on belt 9 is moderate to be in less state, tensiometer institute tension
Power is smaller, and it transmits pulling force signal to controller 7, and controller 7 judges that ribbon conveyer is in the state of normal operation, and will
As a result control centre is fed back to.
When the ribbon conveyer of lower section is out of service due to failure or other reasonses, as shown in Figures 3 and 4, now
The normal operation of ribbon conveyer 10 of top, coal is thrown to the ribbon conveyer of lower section, coal is in lower section ribbon conveyer
Connect and constantly accumulated at coal, form dump 11, in this process, because dump 11 constantly increases, suffered gravity is continuously increased, then
Pulling force suffered by tensiometer also constantly increases, and tensiometer transmits suffered value of thrust to controller 7, by controller 7 according to pulling force

Move.I.e. when coal makes spring tension meter 6 and symmetrical spring 8 be stretched at utmost connecing at coal accumulation to a certain extent, middle support
Roller 3 drops to minimum point, it is impossible to touches frame, therefore will not be disturbed during spring tension 6 dynamometry of meter by frame.
In order that the measurement data of spring tension meter 6 is effective, it is necessary to assure middle idler roller 3 is in vacant state all the time, and in
The height of carrying roller 3 is determined by the spring tension meter 6 and symmetrical spring 8 being suspended on roller rack 2.If middle idler roller 3 touches
Frame 1, then spring tension meter 6 will be interfered.Therefore according to such scheme, after coal piling situation occurs, in spring tension meter 6
Even if spring and symmetrical spring 8 reach maximal tensility, middle idler roller 3 drops to minimum point and is also not readily accessible to frame 1, therefore bullet
The measurement data of spring tensiometer 6 is not by the interference of frame 1.
