Buried hole well drilling rock debris collecting device

Abstract

The invention discloses a buried hole well drilling rock debris collecting device. The buried hole well drilling rock debris collecting device comprises a rectangular box body with an opening in the upper end, a vibration screen net, a conveying belt and a burying pipe, the rectangular box body is mounted in a burying hole, the burying pipe sleeves a drill rod, the lower end of the burying pipe isin abut joint with the burying hole, the burying pipe penetrates through the bottom of the rectangular box body in a seal manner, the vibration screen net is slantly mounted in the rectangular box body, the burying pipe movably penetrates through the vibration screen net, the inclined bottom end of the vibration screen net is provided with a conveying belt, the bottom of the rectangular box bodyis provided with two rows of silt discharging holes, the silt discharging holes are located below the vibration screen net, the silt discharging holes communicate with a ground water draining ditch, rough broken stone falls in the conveying belt to be fed into the box body away from the drill hole position, rock debris collecting is easy, after drilling is finished, the conveying belt reversely rotates, the broken stone is brought for backfilling, the silt falls in the box body and is discharged in time through the silt discharging holes, after screening, the silt discharging holes can be prevented from being blocked, the silt discharging efficiency is improved, the burying pipe achieves the conveying effect, and the rock debris and silt generated by drilling can flow into the vibration screen net.

Description

technical field [0001] The invention belongs to the technical field of ground source heat pump systems, and relates to a cuttings collection device for underground hole drilling. Background technique [0002] At present, in the ground source heat pump system, the drilling cuttings are not uniformly collected when the buried hole is drilled, and there is no better cuttings collection device. During the working process of the drilling rig, the cuttings in the drilling hole are ejected from around the hole under the action of the drilling rig. On the one hand, the cuttings and the discharged water are not easy to separate, and on the other hand, it is not easy to collect cuttings and backfill the buried hole. Only relying on the blocking of the drilling rig It is difficult for the plate to completely collect the discharged cuttings, and the amount of discharged cuttings to be cleaned is large. Contents of the invention [0003] The technical problem to be solved by the prese...
