A portable sampler for geological exploration

Abstract

This utility model relates to the field of geological sampling equipment, and more particularly to a portable sampler for geological exploration. In this portable sampler for geological exploration, the serrated structure of the blade structure effectively reduces the lateral shear resistance of the soil as the collected soil passes through it. When the sampling tube is advanced or withdrawn from the soil, the serrations cut the soil rather than compress it. This cutting action greatly reduces the force required to push the sampling tube, making soil sampling easier. The outer surface of the sampling tube is also equipped with a grip and a support base. The bottom of the support base is inserted into the soil surface through an anti-slip stud structure, providing an anti-slip effect. This solves the technical problem that when the soil moisture is high, the resistance encountered during manual insertion of the sampling tube for sampling is large, and it is easy to deviate from the original trajectory.

Description

Technical Field

[0001] This utility model relates to the field of geological sampling equipment, and in particular to a portable sampler for geological exploration. Background Technology

[0002] In geological exploration, sampling tubes are used to collect soil samples. These tubes preserve the vertical stratification of the soil, which is crucial for analyzing sedimentary environments, lithological variations, and geological ages. Compared to digging with a shovel, sampling tubes can collect samples from deeper, denser soil layers while maintaining sample integrity and minimizing the impact of external disturbances on the data. Sampling tubes typically involve manual insertion. In areas with complex geological conditions, mechanical equipment is difficult to use for sampling. Therefore, manual sampling with tubes can improve sampling efficiency and expand the sampling range. However, when the soil moisture is high, the insertion of the sampling tube faces significant resistance. In this case, the tube may not maintain a straight line and is prone to deviating from its intended trajectory. High moisture can also cause soil samples to adhere to the inside of the tube, making it difficult to retrieve complete samples, or even resulting in sample loss or breakage, severely affecting the accuracy of subsequent laboratory analysis. Utility Model Content

[0003] To overcome the drawbacks of high resistance and easy deviation from the intended trajectory when manually inserting the sampling tube into the soil for sampling when the soil moisture is high, this utility model provides a portable sampler for geological exploration.

[0004] The technical solution of this utility model is: a portable sampler for geological exploration, including a sampling tube; a cavity structure is provided inside the sampling tube; a pointed cone structure is provided at the bottom of the sampling tube; a blade structure is provided in the pointed cone structure; and a plurality of serrated structures are provided in the blade structure.

[0005] To further explain, the outer surface of the sampling tube is slidably connected to a handle.

[0006] To further explain, a support base is fixed to the bottom of the grip tube.

[0007] To further explain, the bottom of the support base is equipped with several anti-slip nail structures.

[0008] To further explain, a push plug is slidably connected inside the sampling cylinder; a push rod is fixedly connected to the push plug.

[0009] To further explain, the push plug has a ring-shaped groove structure; the sampling cylinder has a locking block structure, and the locking block structure is initially inserted into the ring-shaped groove structure; the upper side of the push plug has a through groove structure adapted to the locking block structure, and the through groove structure is connected to the ring-shaped groove structure.

[0010] To further clarify, the push rod is made of solid steel.

[0011] Compared with the prior art, this utility model has the following advantages: This utility model provides a portable sampler for geological exploration. After the sampling tube is inserted into the soil, it continuously collects soil into the cavity structure. When the collected soil passes through the blade structure, the serrated structure of the blade structure effectively reduces the lateral shear resistance of the soil. When the sampling tube is pushed into or pulled out of the soil, the serrations can cut the soil rather than compress it. This cutting action greatly reduces the force required to push the sampling tube, making soil sampling easier. The outer surface of the sampling tube is also equipped with a grip and a support base. The bottom of the support base is inserted into the soil surface through an anti-slip nail structure, providing an anti-slip effect and allowing the sampling tube to be inserted straight down into the soil for sampling, preventing the sampling tube from deviating from its intended trajectory. This utility model, a portable sampler for geological exploration, solves the technical problem that when the soil moisture is high, the resistance encountered when manually inserting the sampling tube into the soil for sampling is large, and it is easy to deviate from the original trajectory.

Detailed Implementation

[0016] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0017] Example: A portable sampler for geological exploration, such as... Figures 1-3As shown, it includes a sampling cylinder 1, a grip tube 2, and a support base 3; the sampling cylinder 1 has a cavity structure 101 inside; the bottom of the sampling cylinder 1 has a pointed cone structure 102; the front and rear sides of the pointed cone structure 102 each have two blade structures 103; each blade structure 103 has several serrated structures 104; the outer surface of the sampling cylinder 1 is slidably connected to the grip tube 2; the bottom of the grip tube 2 is fixedly connected to the support base 3; the bottom of the support base 3 has several anti-slip nail structures 301.

[0018] like Figures 1-3 As shown, a push plug 5 is slidably connected inside the sampling cylinder 1; a push rod 4 is fixedly connected to the push plug 5; an annular groove structure 501 is formed on the push plug 5; two locking blocks 105 are provided on the sampling cylinder 1, and the two locking blocks 105 are initially inserted into the annular groove structure 501; two through groove structures 502 adapted to the locking blocks 105 are formed on the upper side of the push plug 5, and the through groove structures 502 are connected to the annular groove structure 501; the push rod 4 is made of solid steel material, and when the user presses down the push rod 4 to move the push plug 5 downward, the weight of the solid steel material used in the push rod 4 can be used to increase the downward pushing force on the push plug 5.

[0019] During use, the user holds the grip tube 2 and inserts the sampling cylinder 1 into the soil. The locking structure 105 of the sampling cylinder 1 is initially locked in the annular groove structure 501 of the push plug 5, fixing the sampling cylinder 1 and the push plug 5 in a fixed state. The user uses a hammer to continuously strike the push rod 4. The push rod 4, impacted by the hammer, continuously pushes the push plug 5, causing the sampling cylinder 1 to penetrate deeper into the soil. When the support base 3 below the grip tube 2 contacts the soil surface, the support base 3 is blocked by the soil and will not sink into it. The anti-slip nail structure 301 of the support base 3 is hammered into the soil to provide an anti-slip effect, allowing the sampling cylinder 1 to be inserted straight down into the soil for sampling, preventing the sampling cylinder 1 from having a trajectory. The phenomenon of displacement occurs as the cone structure 102 at the lower end of the sampling tube 1 is continuously driven into the soil. The soil is continuously pressed into the cavity structure 101 of the sampling tube 1 for collection. At the same time, the blade structure 103 with serrated structure 104 on the cone structure 102 continuously cuts through the collected soil. The serrated structure 104 of the blade structure 103 can effectively reduce the lateral shear resistance of the soil. When the sampling tube 1 is pushed into or pulled out of the soil, the serrations can cut the soil instead of squeezing it. This cutting action greatly reduces the force required to push the sampling tube 1, especially in harder or cohesive soil layers. It can prevent the sampling tube 1 from getting stuck or deformed due to excessive resistance, making soil sampling easier.

[0020] After completing the process of collecting soil samples into the cavity structure 101 of the sampling tube 1, the user directly pulls the push rod 4 to pull the sampling tube 1 out of the soil, then aligns the lower end of the sampling tube 1 with the carrying collection container, and then rotates the push rod 4 to drive the push plug 5 to rotate until the through groove structure 502 of the push plug 5 aligns with the locking block structure 105 of the sampling tube 1. Then the user pushes the push rod 4 to drive the push plug 5 to move downward along the sampling tube 1. At this time, the locking block structure 105 of the sampling tube 1 will leave along the through groove structure 502 of the push plug 5, so that the sampling tube 1 is no longer fixed to the push plug 5. During the process of the push plug 5 moving downward along the cavity structure 101 of the sampling tube 1, it can push the soil collected in the cavity structure 101 downward into the carrying collection container, thus realizing the quick completion of soil sampling and removal.
