Sampling pipe cutting equipment

The invention provides sampling pipe cutting equipment. In the work process, the bottom of a bearing case is placed upwards, a to-be-cut sampling pipe is pushed into a conveying pipe from a first penetrating hole and is connected to the closed end of the conveying pipe in an abutting manner, and a cutting motor drives a cutting blade through a cutting shaft to rotate to cut the part, contained ina cutting trough, of the sampling pipe. In the process that the to-be-cut sampling pipe is cut by a cutting mechanism, an air blower blows air towards the direction of the cutting trough through an air blowing pipe and an air blowing head to blow off scraps generated by cutting from the cutting trough, and scraps generated by cutting rapidly fall into a sundry storage box under the action of windpower and gravity. The to-be-cut sampling pipe is partially exposed out of the bearing case, so that after the current sampling pipe is cut, a user draws out the cut sampling pipe from the conveying pipe through the first pene
