摘要

PURPOSE: A sample picking device is provided to determine the number of sample picking according to load suitable for a related law and to enable a right amount of samples to be picked through a simple process. CONSTITUTION: A sample picking device comprises a picking unit(13), a sorting chute(15), a grinder(16), a mixer(17), and a controller(22). The picking unit picks coal transferred through a unload conveyor unit(11) at a terminal. The sorting chute is divided into first and second transfer paths(15a,15b) so that the picked samples are held and can be sorted. The grinder grinds the coal transferred through the sorting chute. The mixer stores and then mixes a given amount of grinded coal. The controller controls the operation of all the instruments.
