[0023] The conveying channel comprises a feeding port 13 arranged at the top of the sound insulation cover 8, a hopper 18 arranged below the jaw crusher 1 and a receiving hopper 9 arranged below the pair roller crusher 2.

[0024] When the sample enters the unit from the feeding port 13, the sample is first coarsely crushed by the jaw crusher 1, the coarsely crushed sample directly enters the pair roller crusher 2 through the hopper 18 for medium crushing, and the medium crushed sample falls into the receiving hopper 9, so that the coarse crushing and medium crushing of the sample are completed at one time; in this way, the labor intensity is reduced, the work efficiency is improved, and the land occupation of the crushing equipment is reduced.
