The conveying mechanism of the device can enable the soil generated by drilling to be collected and transported in the trolley below by directly dropping the accumulated soil to the soil outlet after being conveyed to the soil outlet through the collection of the collection box, so that the workload of workers is reduced, time and labor are saved, and the soil generated by drilling is prevented from being backfilled into holes.

Further, a sleeve is arranged below the conveying mechanism and fixedly connected with the bottom of the collecting box, and the spiral drill rod penetrates through the sleeve. The sleeve wraps the soil conveyed by the spiral drill rod to prevent the soil from flying out due to the rotation of the spiral drill rod, so that the soil is accumulated between the sleeve and the spiral drill rod and then is conveyed to the conveying mechanism along with the driving of the spiral drill rod to fall into the collecting box, and the situation that the soil splashes due to overlarge drilling speed during drilling is avoided

Further, the side that drilling car was equipped with elevating system is equipped with the pile frame, pile frame and drilling car fixed connection, elevating system sliding connection is in the side that the pile frame kept away from the drilling car. The pile frame is convenient for lifting the lifting mechanism, so that the lifting mechanism can lift according to a specified track.

Further, the conveying mechanism is fixedly connected to the pile frame and located on the same side with the lifting mechanism. The pile frame optimizes the connection between the conveying mechanism and the drilling vehicle, so that the conveying mechanism and the lifting mechanism are positioned on the same vertical plane.

Further, the upper end of the drilling vehicle is provided with a control chamber, a controller is arranged in the control chamber, and the control chamber is connected with the lifting end of the lifting mechanism, the first motor and the second motor through electric signals. The control room facilitates the use of the device, and enables staff to control the device more simply and quickly.

Further, a baffle is annularly arranged at the position of the spiral drill rod penetrating through the collecting box, and the baffle is inclined downwards from the spiral drill rod into the collecting box. The baffle guides the falling soil to enter the collecting box, and the soil is prevented from accumulating on the upper wall of the collecting box.
