Detailed Description
Referring to fig. 1, 2, 3 and 6, the conical head a15 is fixed at the upper end of a plurality of barrier strips a11 on the inner wall of the casing 14 of the casing drilling machine 1, and the conical head B223 is fixed at the lower end of a plurality of barrier strips B220 on the outer wall of the left semi-cylinder 211 and the right semi-cylinder 212 of the soil-extracting device a2 and the soil-extracting device B3, so that when the cylinder body composed of the left semi-cylinder 211 and the right semi-cylinder 212 of the soil-extracting device a2 and the soil-extracting device B3 is inserted into the casing 14 of the casing drilling machine 1, it is not necessary to precisely position the cylinder body, even when the conical head B223 on the outer wall of the left semi-cylinder 211 and the right semi-cylinder 212 of the soil-extracting device a2 and the soil-extracting device B3 hits against the inner wall of the casing 14 of the casing drilling machine 1 or the conical head a15 of a plurality of barrier strips a11 on the inner wall of the casing 14, the conical head 2 and the soil-extracting device B3 are easily inserted into the casing 14 due to the sliding action of the conical head B3614, referring also to fig. 6, the relative offset arrangement of the plurality of barrier strips a11 and the plurality of barrier strips B220 is also for the convenience of inserting the left and right half cylinders 211, 212 of the earth-moving devices a2, B3 into the casing 14; referring to fig. 1, the plurality of drill bits 13 of the casing 14 cut the rock into annular grooves first, so that the middle columnar rock is separated from the peripheral rock, and thus the cutting head 214 of the borrowing device a2 can easily cut the arc surface of the columnar rock into a spiral groove from top to bottom, the borrowing device a2 can cut the columnar rock into a spiral groove only by means of self gravity without additionally increasing vertical force, which is also the reason that the blocking strip B220 of the borrowing device a2 is not designed with a blocking block 225; referring to fig. 1, 3 and 5, the lower ends of the left half cylinder 211 and the right half cylinder 212 of the soil sampling device a2 and the soil sampling device B3 both have sharp corners, which is mainly convenient for the left half cylinder 211 and the right half cylinder 212 of the soil sampling device a2 and the soil sampling device B3 to be inserted into the residual soil in the casing 14, and is beneficial for the soil sampling device a2 and the soil sampling device B3 to be in place; referring to fig. 10, the design of the locking groove 224 of the blocking strip a11 of the casing 14 and the design of the locking block 225 of the blocking strip B220 of the left half cylinder 211 and the right half cylinder 212 of the casing drilling machine B3 are matched to connect the casing 14 of the casing drilling machine 1 and the soil sampling device B3 into a whole, and the soil sampling bit a31 and the soil sampling bit B32 of the soil sampling device B3 can forcibly cut broken stones, especially boulders, by utilizing the strong downward force and the strong rotating force of the casing 14 of the casing drilling machine 1 and push the cut boulders into the barrel bucket, so the invention is not only suitable for cohesive soil and gravels, but also suitable for sampling soil of the boulders and full-section rocks.
