And obtaining credible testing result should depend on conventional testing processing. Among the 3 processing of sampling, making and test, sampling may cause the most serious errors, therefore, using the sampling machine should beone of the most effective means. The machine is the transmission system with motor as power that transmits drive through gear reducer, sprockets , and uses the rod on big sprockets that makes the focus of partial ship moving upwardly. Sampling time - interval is adjusted through time relay. Install the frame of sampling machine that coincides with the frame of belt conveyor. Entire drive device is set upon frame of sampling machine. This machine, organization pact, manufacturing costs are low, sampling coal is accurate and reliable, and automation level is it is an ideal tool of replacing artificial sampling and has extensive popularize application value.
