The vertical drill bit can vertically drill holes in the soil geological exploration area, and the rotating motor carries the sensing block downward. When the distance sensed by the vertical distance sensor is the same as the distance set by the controller, the electric cylinder is closed by the controller, and the vertical middle soil geological exploration drilling operation is synchronously realized, the exploration drilling area is wider, and the exploration drilling efficiency is improved.

[0016] Based on the mutual influence of the above-mentioned multiple effects, firstly, multiple inclined drill bits can be synchronously adjusted to different angles, and then multiple inclined drill bits can simultaneously realize drilling exploration in three different directions, and at the same time, the vertical drill bit synchronously realizes vertical middle drilling exploration. In summary, there is no need to perform drilling exploration one by one, and multiple drill bits can be synchronously adjusted to different angles to realize large-area synchronous exploration drilling, greatly improving the exploration drilling efficiency.
