Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a tuff sampling device. Background Technology

[0002] Tuff is a type of volcanic clastic rock. More than 50% of the volcanic clastic material it is composed of particles with a diameter of less than 2 mm. Its main component is volcanic ash. It has a loose and rough or dense appearance. When it has stratification, it is called layered tuff. Due to different compositions, it has a variety of colors, such as purplish-red, grayish-white, and grayish-green. When sampling and testing tuff, a sampling device is required.

[0003] Currently, tuff sampling devices on the market, when removing rock from inside the sampling tube, cannot effectively remove the rock upwards because the bottom of the sampled rock is not completely severed from the rock mass, reducing work efficiency and presenting certain limitations. Related technologies, during sampling, utilize a rotating screw rod that enters the rock. Due to the significant resistance between the screw rod and the sampled rock, the sampling tube is lifted upwards to remove the rock from the inside. After the sampling tube is removed, manually pulling the push rod disengages the locking rod from the slot on the screw rod, disassembling the screw rod from the sampling tube. Pushing the screw rod downwards then pushes out the sampled rock from inside the sampling tube. While this method can remove the rock, in actual use, the bottom of the sampled rock is still not separated from the rock mass, resulting in a lack of rock integrity during removal. Furthermore, the threads on the screw rod experience fatigue failure during removal, and the forceful pulling method also reduces the screw rod's lifespan, making it limited and inconvenient to use.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0027] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0028] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0029] Currently, tuff sampling devices on the market have limitations in efficiency when removing the rock from inside the sampling tube. This is because the bottom of the rock block is not cut off from the sampling tube, which prevents the sampling tube from effectively removing the rock from the tube.

[0030] The existing technology involves a rotating auger that enters the rock during sampling. Due to the significant resistance between the auger and the rock, the sampling cylinder is lifted upwards to remove the rock. After the cylinder is removed, manually pulling a push rod disengages a locking lever from the groove on the auger, detaching the auger from the sampling cylinder. Pushing the auger downwards then pushes out the rock. While this method removes the rock, in practice, the bottom of the rock remains attached to the rock mass, compromising the rock's integrity during removal. Furthermore, the threads on the auger experience fatigue failure during extraction, and the forceful pulling method reduces the auger's lifespan. This design has limitations and is inconvenient to use.

[0031] To address some of the problems in the related technologies, this application provides a tuff sampling device. When needed, the drive mechanism 12 is operated so that the sampling tube 13 samples the tuff. At the same time, the adjustment mechanism 25 is activated to adjust the position of the cutter head 27 and the adjustment mechanism 23 is opened so that the cutter head 27 cuts the tuff. When the sampling tube 13 is then removed, the tuff sample is taken out with it, which is more convenient and faster, and improves the convenience of the device.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-3 This application provides a tuff sampling device, including a main component 1; the main component 1 includes: a base 11, on which a driving mechanism 12 is disposed; a sampling cylinder 13, disposed on the driving mechanism 12; a separation component 2 is disposed inside the sampling cylinder 13; the separation component 2 includes: a first cavity 21, opened inside the sampling cylinder 13; a ring 22, rotatably connected to the first cavity 21; an adjustment mechanism 23, disposed inside the first cavity 21; a second cavity 24, opened inside the ring 22; an adjustment mechanism 25, disposed inside the second cavity 24; a slider 26, slidably connected to the second cavity 24; and a cutter head 27, fixedly connected to the inner side of the slider 26.

[0034] In use, after installing the drive mechanism 12 and sampling cylinder 13 to the designated position via the base 11, the drive mechanism 12 is turned on. While adjusting the height of the sampling cylinder 13, the cylinder rotates until it contacts the tuff, allowing it to enter the tuff interior for cutting. Then, the second adjustment mechanism 25 is activated, along with the first adjustment mechanism 23. Activating the second adjustment mechanism 25 adjusts the position of the slider 26, causing it to drive the cutter head 27 to slide inwards towards the sampling cylinder 13. Activating the first adjustment mechanism 23 adjusts the position of the ring 22. The angle is adjusted so that the ring 22 drives the slider 26 and the cutter head 27 to rotate around the tuff. The cutter head 27 cuts the tuff, and the cutting area is increased by continuously opening the adjustment mechanism 25. After the tuff sample is separated from the tuff, the sampling cylinder 13 is lifted by the drive mechanism 12. The slider 26 and the cutter head 27 on the inside of the sampling cylinder 13 limit the tuff sample, so that the complete sample can be taken out. Finally, the adjustment mechanism 25 is driven again so that the slider 26 and the cutter head 27 slide away from the tuff sample, and the tuff sample can be taken out from the sampling cylinder 13.

[0035] In some embodiments, the adjustment mechanism 25 consists of a micro motor and a lead screw. By turning on the micro motor, its output end drives the lead screw to rotate, and the position of the slider 26 is adjusted through the threaded connection between the lead screw and the slider 26.

[0036] In some embodiments, the adjustment mechanism 23 includes: a motor 231, fixedly connected to the cavity 21; a gear 232, fixedly connected to the output end of the motor 231; and a gear disk 233, fixedly connected to the top of the ring 22, wherein the gear 232 meshes with the gear disk 233. In use, the motor 231 is turned on, and its output end drives the gear 232 to rotate. At the same time, through meshing with the gear disk 233, the gear disk 233 drives the ring 22 to rotate, thereby realizing the adjustment of the angle of the ring 22.

[0037] In some embodiments, the depth of the second cavity 24 is greater than the length of the slider 26, so that the slider 26 and the cutter head 27 can slide completely into the second cavity 24.

[0038] In some embodiments, the sampling cylinder 13 is provided with a disassembly assembly 3; the disassembly assembly 3 includes: a first cylinder 31, which is fixedly connected to the driving mechanism 12; a second cylinder 32, which is disposed at one end of the first cylinder 31, and the sampling cylinder 13 is composed of the first cylinder 31 and the second cylinder 32; a groove 33, which is opened on the outside of the second cylinder 32; and a bolt 34, which is threadedly connected to the first cylinder 31, and the second cylinder 32 is fixedly connected to the first cylinder 31 by the bolt 34.

[0039] In use, rotate bolt 34 to detach it from cylinder 1 31 and cylinder 2 32, then pull cylinder 2 32 outward to separate cylinder 2 32 from cylinder 1 31, thereby facilitating the maintenance and replacement of the internal structure of cylinder 2 32 and cylinder 1 31.

[0040] In some embodiments, the disassembly assembly 3 further includes a positioning hole 35, which is formed on the second cylinder 32 to improve the stability of the connection between the first cylinder 31 and the second cylinder 32 during use.

[0041] In some embodiments, the groove 33, the bolt 34 and the positioning hole 35 are a group, and multiple groups are provided between the first cylinder 31 and the second cylinder 32, so that multiple bolts 34 can be used at the same time to improve the fixing effect.

[0042] In some embodiments, the cutter head 27 is provided with a bevel to facilitate cutting the tuff sample.
