[0026] In the embodiment, the sampling mechanism comprises a sampling head 2, a material infeed sensor 3, a transfer belt 4, a primary crusher 5, a secondary crusher 6, a screening machine 7 and a size-reducing machine 8.

The discharge end of the sampling barrel 102 is located above the transfer belt 4. The material infeed sensor 3 is arranged on the feeding belt conveyor 1 in front of the sampling head 2. The material infeed sensor 3 and the sampling head 2 are respectively connected with a control device. When the feeding belt conveyor 1 drives the calcium carbide samples to the position of the material infeed sensor 3, the position of the calcium carbide samples is detected by the material infeed sensor 3, so as to facilitate the control device to control the sampling head 2 to sample according to the detection signal.
