Journey is as follows: when the sensor sensing of abandoning 5 bottom of sample bucket coal scuttle is to there is coal charge entrance, motor delayed startup 20min abandons sample bucket coal scuttle
5 rise in rail sliding slot 10, and two rows of idler wheels in coal scuttle trolley base respectively enter tipping bucket sliding slot 10.2 and retaining sliding slot
10.4,60 ° are turned over after abandoning sample bucket coal scuttle 5, completes tipping bucket movement, coal will be abandoned and retract and pour into ring road belt feeder 3.The delay of motor 4 is opened
The coal charge for the upper levels processes such as dynamic effect is, which is all discharged to, to be abandoned in sample bucket coal scuttle 5.Last ring of the present invention in coal property test system
Section " abandons sample to return "；One complete system requirements send the coal sample taken to anti-original place, avoids the normal operation for influencing big system；Inspection
The coal sample surveyed, which is fallen into, abandons sample bucket coal scuttle 5, and system controls the motor 4 at the top of sliding slot and rotates, and reel winds steel cable and pulls coal scuttle
Along sliding slot rising, overturning is gone straight up to, the coal sample in coal scuttle pours into the belt feeder of traveling, completes to abandon sample.
