Sampling device is applied on belt conveyor, and the belt conveyor has conveyer belt, and the automatic sampling apparatus includes set on defeated
The rack with top and the electric-control system set on rack side are sent, the frame surface is successively set along belt conveyor traffic direction
Have retarder, shaft coupling and a shaft, the retarder by electric control system controls, and the retarder by shaft coupling with it is described
Shaft connection, the shaft outer wall are respectively equipped with bearing block in rear and front end, and the shaft outer wall is equipped between two bearings seat
Sampling bucket, one side opening of the sampling bucket, opening bottom is equipped with the arc coal scraper plate vertical with the running direction of conveyor belt；
Sampling bucket rotation is driven when shaft rotates, at this time the transversely adjacent conveyor belt surface sampling of the arc coal scraper plate；The rack exists
It is equipped on the outside of the shaft close to switch, the sampling bucket close to inductive switching into rotation transmits signals to electricity
Control system control retarder stops working, and stops at the arc coal scraper plate on sampling bucket far from conveyer belt coal stream position；It is described
Electric-control system can realize that interval is mined by setting time.
Preferably, the electric-control system sets sampling period, a sampling period knot by being equipped with the time relay
Next sampling period is waited according to setting time after beam.
The conveying radian of the arc coal scraper plate cambered surface and the conveyer belt coincide substantially, can accomplish neither to damage conveyer belt
Coal stream tunneling boring can be swept again, completely take out coal sample；When not sampling, the arc coal scraper plate is avoided far from conveyer belt coal stream
Scrape band coal stream.
When the utility model is used, starting retarder drives shaft rotation, shaft drives sampling bucket rotation, passes through arc
Coal scraper plate collects the coal stream tunneling boring on conveyer belt, described close to switch when bucket rotation to be sampled is to far from conveyer belt coal stream
It senses sampling bucket, inductive signal is transferred to control system, braking stops retarder, and sampling bucket is rested on far from conveyer belt coal
The coal sample in sampling bucket is at this time taken out in the position of stream；It is equipped with the time relay in the control system, passes through the time relay
The sampling period is set, waits next sampling period according to setting time after a sampling period.
Compared with prior art, the utility model structure is simple, and design rationally, not only can ensure that and realize conveyer somewhere coal
Flow it is full face take, keep coal sample representative, and the labor intensity and security risk of worker can be effectively reduced.

Specific embodiment
It is an embodiment of the present invention referring to attached drawing 1, discloses a kind of automatic sampling for belt conveyor
Device is applied on belt conveyor, and the belt conveyor has conveyer belt 1, and the automatic sampling apparatus includes set on defeated
Send the rack 2 of the top of band 1 and the electric-control system set on 2 side of rack, 2 surface of rack along belt conveyor traffic direction according to
Secondary to be equipped with retarder 4, shaft coupling 5 and shaft 7, the retarder 4 is by electric control system controls, and the retarder 4 passes through connection
Axis device 5 is connect with the shaft 7, and 7 outer wall of shaft is respectively equipped with bearing block 6 in rear and front end, and 7 outer wall of shaft is two
