Graphite ore crushing and sampling device

The invention belongs to the technical field of graphite ore crushing and sampling, and particularly relates to a graphite ore crushing and sampling device which comprises an equipment main body, a pair of crushing rollers are arranged in the equipment main body, a feeding port is formed in the surface of the equipment main body, and an exhaust pipe is fixedly mounted on the surface of the equipment main body; a fan is fixedly mounted on the surface of the exhaust pipe, the exhaust pipe is communicated with the interior of the equipment main body, and a sampling barrel is arranged in the equipment main body; when the equipment main body crushes graphite ore, the fan is started, the fan enables negative pressure to be generated in the exhaust pipe, the negative pressure sucks dust generated when the graphite ore is crushed by the crushing roller into the exhaust pipe, the dust is finally blown to a position far away from a worker along with the fan, and the crushed graphite ore can fall into the sampling barre
