Problems solved by technology

[0003] In the current sampling device, when sampling shallow soil, the soil-taking tool is generally a cylindrical structure. When taking soil, the cylinder is inserted into the ground, and after being pulled out, the inner cavity of the cylinder is taken out to obtain the soil. However, at present, this method mainly used can only obtain disturbed soil when drilling, and the sample is damaged to a certain extent, which will have a certain impact on the accuracy of exploration, and the soil sample on the inner wall after drilling However, it is complete, but even if the existing soil-borrowing tools can be removed, there are disadvantages such as troublesome operation and inability to be taken off as a whole, which affects the accuracy of later detection, so it is necessary to improve the existing soil-borrowing tools, resulting in a more complete sample of the soil layer

Embodiment 1

[0025] Such as Figure 1-7 The shown soil sampling device for exploration includes a bottom plate 1, the bottom plate 1 can be circular or rectangular, and it is rectangular in this embodiment; A baffle 3 is sleeved, and the baffle 3 is installed on the base plate 1 and is fixedly connected, that is, a baffle 3 is fixedly installed around the upper surface of the rectangular base 1, and a fixed plate 2 is installed in the middle of the baffle 3; A first through hole 4 is provided in the plate 2, a side soil fetching mechanism is installed in the first through hole 4, and a drive mechanism for driving the side soil fetching mechanism is fixedly installed on the upper end of the fixed plate 2, that is, by setting the drive mechanism Sliding outwards into the soil layer with the side soil fetching mechanism, after obtaining suitable soil, the driving mechanism takes it back into the baffle plate 3, thereby completing the soil sampling work, realizing the overall removal of the so...

Embodiment 2

[0029] This embodiment is further optimized on the basis of Embodiment 1. The surface of the fixed rod 9 is provided with a scale mark 13, and the outside of the fixed rod 9 is equipped with a support mechanism, that is, by setting the support mechanism to cooperate with the scale mark 13, it is convenient to use the scale mark 13 The soil fetching operation is carried out at a suitable depth, and the soil fetching position is more convenient and accurate. Specifically, the support mechanism includes a support rod 12, and a sliding sleeve 11 is fixedly installed in the support rod 12, and a fixed rod is provided in the sliding sleeve 11 9 matched second through holes 17, two second teeth 18 are fixedly installed in the second through holes 17, and the two second teeth 18 are arranged symmetrically with respect to the sliding sleeve 11, and the fixing rod 9 First teeth 16 are installed on both sides, and the first teeth 16 are rotated by 90° to cooperate with the second teeth 18...

Abstract

The invention relates to a soil sampling device for exploration, and belongs to the technical field of exploration equipment. The soil sampling device comprises a bottom plate, a fixed plate is fixedly mounted on the upper surface of the bottom plate, a baffle plate sleeves the outer side of the fixed plate, the baffle plate is mounted on the bottom plate and is fixedly connected with the bottom plate, and a first through hole is formed in the fixed plate; and a side surface soil sampling mechanism is mounted in the first through hole, and a driving mechanism for driving the side surface soilsampling mechanism is fixedly mounted at the upper end of the fixed plate. The driving mechanism is arranged to be matched with the side surface soil sampling mechanism, the side surface soil samplingmechanism is pushed outwards under the driving of the driving mechanism to obtain a complete soil layer, then the obtained soil is brought back to the interior and taken out integrally, the completeness of an exploration sample is guaranteed, and the exploration accuracy is improved; meanwhile, a supporting mechanism is arranged for matching, so sampling at a suitable depth is facilitated, the soil sampling device is convenient to operate, the sampling efficiency is improved, and the soil sampling device is more convenient and practical.

Description

technical field [0001] The invention relates to the technical field of exploration equipment, in particular to a soil sampling device for exploration. Background technique [0002] Exploration work is one of the important working methods of engineering geological exploration. Engineering geological exploration includes geophysical prospecting, drilling, pit exploration, etc. Drilling is an important means to obtain accurate geological data under the surface in engineering geological survey. Drilling during surveying should be carried out on the basis of surveying, mapping and geophysical prospecting. Exploration lines and networks should be arranged purposefully and in a planned manner according to survey stage, project scale and complexity of geological conditions. Carry out the principle of sparse first and then dense. In exploration, in order to obtain soil samples at a certain depth, practical soil sampling devices are often required. [0003] In the current sampling...
