AI Technical Summary
When the rock cutting sampler comes into contact with the rock, especially during high-speed rotation or strong propulsion penetration of the hard rock layer, it generates a large vibration force, causing the sampler to deviate from the predetermined trajectory, increase sampling error, and is inconvenient to use.
Weld the guide strips on both sides of the sampler, and the inner strips and slides are installed on the inner wall of the sleeve column to form a stable track guide structure. Through the cooperation of the bracket and the mounting member, the vibration impact is reduced and the sampler moves along the predetermined track.
It improves the stability and convenience of the sampler in the rock layer, reduces sampling errors, and improves the efficiency and accuracy of sampling work.

Description
Technical Field
[0001] The utility model belongs to the technical field of geological exploration, and in particular relates to a rock chip sampler for geological exploration. Background Art
[0002] A rock cutting sampler is a tool specifically designed to collect rock cuttings from rock, soil, or other solid materials. A rotary rock cutting sampler uses a rotating spiral drill bit to drill into the target material and, as it rotates, collects the rock cuttings inside the drill bit or into a specialized collection container. This method effectively collects rock cuttings from various depths with minimal disruption to the surrounding environment. Spiral rock cutting samplers are widely used in geological exploration, mineral resource surveys, geotechnical engineering, environmental monitoring, and other fields. By collecting rock cuttings, we can understand the distribution, properties, and changes of underground rock formations, providing important information for scientific research, engineering design, and construction in related fields.
[0003] Rock chip samplers play a vital role in geological exploration, mineral resource assessment, and geotechnical engineering. They are designed to efficiently and accurately collect rock chip samples from underground rock formations. However, although rock chip samplers can penetrate deep into the rock layer and effectively collect rock chip samples that represent stratigraphic information, it cannot be ignored that the working end of the device, which is in direct contact with the rock, will generate relatively large vibration forces, especially during high-speed rotation or strong propulsion to penetrate hard rock formations. Excessive vibration may cause the sampler to deviate from the predetermined trajectory, increase sampling errors, and thus make the rock chip sampler less convenient to use. Utility Model Content

However, although the rock chip sampler can penetrate deep into the rock layer and effectively collect rock chips representing the formation information when in use, it cannot be ignored that the working end of the device, which is in direct contact with the rock, will generate relatively large vibration forces, especially during high-speed rotation or strong propulsion to penetrate hard rock formations. Excessive vibration may cause the sampler to deviate from the predetermined trajectory, increase the sampling error, and thus make the rock chip sampler appear less convenient when in use.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-4 The utility model provides the following technical solutions: a rock chip sampler for geological exploration, comprising a sampler 1, guide strips 2 are welded on the outer walls of both sides of the sampler 1, and a sleeve column 3 is movably sleeved on the bottom of the sampler 1;
[0019] A discharge port is provided on one side of the main body of the sampler 1. When in use, the sampler 1 will sample the set geological exploration rock. The rock cuttings collected by the sampler 1 will be transported to the outside through the discharge port, thus completing the operation of sampling the rock cuttings. When in use, the geological information here can be obtained by analyzing the rock cuttings.
[0020] Four mounting parts 4 are welded at equal intervals on the outer wall of the sleeve column 3, and a bracket 5 is fixedly installed in the opening of the mounting part 4. The angle between the bracket 5 and the mounting part 4 is 45°. The internal diameter of the sleeve column 3 is larger than the diameter of the sampler 1.
[0021] Preferably, a notch 201 is provided on each side of the guide bar 2. The outer wall of one side of the guide bar 2 is an arc-shaped structure, and the arc-shaped outer wall of the guide bar 2 is in movable contact with the inner wall of the sleeve 3. An inner bar 301 is fixedly mounted on the inner wall of the sleeve 3, and a slide bar 302 is fixedly connected to the other side of the inner bar 301. The inner bar 301 and the slide bar 302 have an L-shaped structure when viewed from above, and every two inner bars 301 and slide bars 302 form a group, and two groups of inner bars 301 and slide bars 302 are symmetrically mounted inside the sleeve 3. The spacing between each group of inner bars 301 and slide bars 302 is adapted to the horizontal length of the guide bar 2, and the size of the slide bar 302 is adapted to the internal size of the notch 201. Each slide bar 302 is movably docked with the inside of a notch 201, and the lengths of the inner bars 301 and slide bars 302 are the same as the length of the sleeve 3.
[0022] When using it, try to choose a relatively flat area as the collection point, and then place the sleeve column 3 on the ground at the collection point. When placing the sleeve column 3, make sure that the four sets of mounting parts 4 and the bracket 5 at the bottom are in stable contact with the ground. This completes the arrangement of the sleeve column 3.
[0023] Next, align the guide strips 2 on both sides of the sampler 1 with the two sets of inner strips 301 and the slide strips 302 inside the sleeve 3, and move the sampler 1 downward. When the sampler 1 moves downward, the notches 201 on both sides of the guide strips 2 will dock with the corresponding slide strips 302, so that the sampler 1 can move downward along a fixed trajectory.
[0024] When collecting rock cuttings samples, start the sampler 1, and the spiral fan blades on the sampler 1 will collect on the rock surface. The vibration generated by the sampler 1 when working will be weakened by the action of the sleeve 3, the mounting part 4 and the bracket 5. In this way, the sampler 1 will work in a more stable state, thereby improving the convenience of using the sampler 1.
