Soil core receiving device for drilling engineering

The utility model relates to the technical field of geological exploration, and discloses a soil core receiving device for drilling engineering, which comprises a base, a mounting frame capable of moving along the direction of the base, and a propulsion shaft for pushing a core, the propulsion shaft is connected with a position-adjustable insertion plate, and a spray head is arranged in the insertion plate; an air inlet pipe is installed in the middle of the propelling shaft of the connecting shaft, and a buffering air bag is installed at one end of the air inlet pipe. The buffering air bag easy to deform is conveniently attached to the end face of the rock core, the conditions that stress is uneven and the rock core is broken due to the fact that the end face of the rock core is irregular are avoided, and it is guaranteed that the rock core is completed; in addition, by controlling the position of the sprayer, the sprayer sprays water between the rock core and the drilling tool, part of rock core debris powd
