Description

Multifunctional sampling device and method for rock and soil exploration Technical Field The invention relates to the technical field of rock and soil exploration, in particular to a multifunctional sampling device and method for rock and soil exploration. Background The rock-soil exploration sampling is an important link in geological exploration work, and relates to the collection of soil, rock or other geological materials from underground for laboratory analysis or field test, wherein the process is important for evaluating geological conditions, determining the properties of the soil and the rock and providing necessary parameters for engineering design, wherein the sampling work plays a critical role in the rock-soil exploration, and not only directly affects the accuracy and reliability of exploration results, but also has a profound effect on the aspects of subsequent engineering design, construction, environmental evaluation and the like. In the prior art, a large number of sampling devices and methods for rock and soil exploration are also disclosed, wherein, as disclosed in China patent publication No. CN111076968A, the sampling device for rock and soil exploration comprises an outer cylinder, a rotating shaft, a cover cylinder and a plurality of tipping buckets, wherein the side wall of the outer cylinder is symmetrically provided with tipping bucket holes, the tipping buckets can be hinged to the edge of the tipping bucket holes in an outward turning manner, the rotating shaft is rotatably and axially arranged in the outer cylinder, a first nut sleeve positioned on one side of the tipping bucket is arranged in the outer cylinder, and a second nut sleeve is arranged in the connecting rod. When the device is used, firstly, holes are drilled in a soil layer to a designated depth, the diameter of each hole is equal to that of the outer cylinder, then the embodiment is integrally inserted into the holes, or the end part of the outer cylinder is connected with a drill bit embodiment to integrally drill into the soil layer to be sampled directly, then the rotating shaft is rotated, the first nut sleeve and the second nut sleeve respectively move in different opposite directions when the rotating shaft rotates through arranging two sections of threads with opposite rotation directions at the lower part of the rotating shaft, after the bucket hole is opened by the cover cylinder, the bucket is extruded to the outer cylinder to overturn, so that the edge of the bucket is inserted into the hole wall of the soil layer, then the whole is reversely pressed to the holes, so that a rock sample at the hole wall enters the bucket, and then the rotating shaft is reversely rotated, so that the bucket is extruded by the cover cylinder, and the sample receives the shearing action of the edge of the cover cylinder and enters the outer cylinder. However, in sampling the rock and soil using the above prior art, there are the following disadvantages: 1. Above-mentioned prior art is in the in-process of exploring the sample to the hole, can't accomplish the rock soil of the different diameters department of same hole and take a sample, need enlarge the diameter of hole and handle, use the sampling device the same with the hole diameter to take a sample work to this hole afterwards, complex operation is difficult to take a sample fast to the rock soil under the different diameters in the hole, increases the sampling cost to the rock soil in the hole, reduces the sampling efficiency to the rock soil. 2. When the rock and soil is sampled in the pre-excavated holes, the soil layer structure is easily influenced by the contact between the surfaces of the holes and the outside, so that the samples on the surfaces of the holes are required to be removed, the influence of the samples on the natural structures of the samples on the surfaces of the samples on the accuracy and the reliability of subsequent exploration are avoided, but the rock and soil on the surface layers of the inner walls of the holes cannot be removed in the prior art, and the sampling effect on the holes is reduced. 3. When the samples at different positions are required to be collected in the same hole, the same work needs to be repeated for a plurality of times to finish sampling the samples at different positions, the samples at different positions cannot be collected in the hole at one time, the sampling time is increased, the sampling efficiency is reduced, and the cost is increased. Thus, under the above stated point of view, the prior art rock sampling means has room for improvement. Disclosure of Invention In order to solve the problems, the invention provides a multifunctional sampling device for rock and soil exploration, which comprises a sampling barrel, wherein an auxiliary barrel with the same diameter is arranged at the upper end of the sampling barrel, a movable pull rope is arranged at the upper end of the auxiliary barrel, a driving unit and
