The invention discloses an improved sampling device, which comprises an outer cylinder with a sampling head at the bottom and a rotatable drill rod sleeved in the outer cylinder, a crushing head positioned in the sampling head is arranged at the bottom of the drill rod, and the drill rod and the outer cylinder are respectively driven by a power transmission mechanism to rotate. Through driving of two sets of power transmission mechanisms, forward and reverse rotation of the sampling head and the crushing head can be achieved, during discharging, the sampling head stops rotating, the crushing head rotates in the reverse direction (relative to the sampling rotating direction), materials are discharged from the bottom end, and discharging is clean. Due to the fact that sawteeth at the lower end of the sampling head have a cutting function during rotary drilling, cutting teeth on the sampling head and cutting teeth on the crushing head enable the sampling head to have an extrusion crushing function under the acti
