MECHANICAL PART-STREAM SAMPLER

摘要

A mechanical part-stream sampler includes a housing positionable over a conveyor belt from which material is to be sampled. The housing encases one or more cutter arms and adjustable cutters. The cutter arms rotate 360 degrees such that the cutters extract a sample of material from the conveyor belt and deposit the sample in a discharge chute in the housing for later analysis. A programmable logic controller and human machine interface screen can be used to operate the sampler and to control the timing and speed of the cutter arms.

1. An apparatus, comprising:
one or more cutters for extracting a sample of material from a moving conveyor belt; a cutter arm connected to each of the one or more cutters; a drive assembly for rotating the cutter arm and cutter at a desired speed relative to the convnor belt from which the sample is to be extracted; a cutter shaft for connecting the drive assembly to the cutter arm; a cutter shaft bearing to secure the cutter shaft in place and to guide the cutter shaft during rotation; a housing assembly, comprising:
a discharge chute to transfer extracted product samples from the cutter to a save sample container; anda discharge chute throat skirt around the discharge chute opening for preventing extraneous material from entering the discharge chute; an exit skirt assembly for directing misplaced material back onto the conveyor belt as it passes through the housing assembly; and control means for operating the apparatus.
