Description
Technical Field
[0001] The invention relates to geological exploration technology, and in particular to a measuring device based on geological exploration profiles. Background Art
[0002] The geological survey profile is sampled by geological hammer, which is not continuous enough, and the hardness of rocks varies, which causes damage to some rocks and makes it difficult to observe their internal conditions. It is also easy to cause some samples to be missed. At the same time, the geological hammer has a slow percussion speed, making it difficult to quickly collect samples. The measurement of geological profiles is an important part of geological surveys. Its purpose is to provide data for exploration design, engineering layout, reserve calculation and comprehensive research. Generally, profile measurement devices are used for geological profile surveys.
[0003] A Chinese invention patent with publication number CN114279403A discloses a profile measuring device based on geological exploration. The profile measuring device based on geological exploration supports the entire device through an adjustment mechanism in conjunction with three first support rods, a second support rod and a third support rod. The geological profile is measured by a measuring instrument and a measuring mechanism. The first mounting rod is rotated by turning the adjustment knob. Under the meshing action between the first gear and the second gear, the second mounting rod can follow the rotation, thereby realizing the angle adjustment of the first support rod. An adjustment mechanism is provided on the top of each first support rod, so that the three first support rods can be controlled separately, and the first support rods at different positions can be adjusted to different angles according to specific usage requirements.
[0004] When the existing equipment is in use, it is necessary to extract rocks at different positions and depths to determine the conditions of the soil layer. When collecting soil, it is necessary to constantly change positions. When carrying, the space occupied is relatively large, which increases the difficulty of carrying, resulting in a certain impact on the progress of the project. At the same time, it is impossible to make specific adjustments to the support angle and height according to different use environments, terrain and other factors, thereby reducing the use effect of the entire measuring equipment and making it inconvenient to perform profile measurements. Therefore, a measuring equipment based on geological exploration profiles has been developed. Summary of the invention

The support column 12 extends to a specified position and then stops, thereby supporting the entire pallet 1, so that the whole remains stable during operation.
[0040] Furthermore, the support assembly 3 is assembled at the lower end of the limit assembly 2, and is used to limit the pallet 1; wherein the support assembly 3 includes a telescopic rod 31, a disc 32 is provided at the lower end of the telescopic rod 31, a plurality of groups of fixed columns 33 are provided at the lower end of the disc 32, and the plurality of groups of fixed columns 33 are evenly distributed at the lower end of the disc 32, and an elastic member 331 is sleeved on the outer surface of the fixed column 33.
[0041] In this embodiment, the telescopic rod 31 is composed of a round rod and a fixed tube, and the outer surface of the round rod is slidably connected to the inner wall of the fixed tube, and the outer surface of the round rod is provided with a clamp or other fixing component to support the telescopic rod 31 after it is moved to a suitable position.

[0044] Specifically, when the push plate 35 is forced to move downward, the extrusion plate 351 is simultaneously driven to move, and when the extrusion plate 351 moves, the protrusion 352 arranged at its lower end is driven to fit with the soil, so that when the soil is extracted, the outer surface of the extraction site is supported to avoid the collapse of the soil in the extracted part, thereby further ensuring the overall stability.
[0045] At the same time, the upper end of the push plate 35 is connected to the elastic member 331 , so that when the push plate 35 stops being subjected to force, the push plate 35 is restored to its initial position by the force of the elastic member 331 .
[0046] Furthermore, a rotating drum 36 is rotatably installed in the middle position of the lower end of the disc 32, and a plurality of groups of movable rods 361 are provided on the outer surface of the rotating drum 36, and the plurality of groups of movable rods 361 are evenly distributed on the outer surface of the rotating drum 36, and a first rotating block 362 is provided at one end of the movable rod 361 away from the rotating drum 36, and a limiting rod 363 is rotatably installed at the end of the first rotating block 362, and a second rotating block 364 is rotatably installed at the lower end of the limiting rod 363, and a swing plate 37 is provided at the lower end of the second rotating block 364.
[0047] Specifically, when the rotating drum 36 rotates, the movable rod 361 arranged on its outer surface is synchronously driven to rotate.

[0049] Specifically, the power member 39 is a device with power output such as a motor, and is connected to an external control device. When the power member 39 is started, it synchronously drives the rotating shaft 38 arranged at its output end to rotate. When the rotating shaft 38 rotates, it drives the rotating drum 36 to rotate.

[0053] At the same time, the driving member 23 is limited by the protection block 22 , and the fixing plate 24 is supported in cooperation with the protection block 22 .
[0054] Furthermore, a slider 261 is slidably mounted on the inner wall of the slide groove 26, and a clamping block 25 is disposed on the outer surface of the slider 261.

[0056] Further, push rods 262 are symmetrically arranged on the outer surface of the slider 261, and a clamping block 263 is rotatably installed at one end of the two push rods 262 away from the slider 261.

[0058] The assembleable extraction equipment enables quick collection and transfer during transportation, thus reducing the time required for transportation.
[0059] Furthermore, limit blocks 211 are symmetrically arranged at the ends of the bottom plate 21 and on both sides of the protection block 22 , and a clamping rod 29 is rotatably installed at the end of the fixing plate 24 , and the outer surface of the clamping rod 29 is in contact with the outer surface of the slider 261 .
[0060] Specifically, the end of the extraction device is supported by a limit block 211 disposed on the bottom plate 21, and the outer surface of the limit block 211 is provided with a component having an anti-slip function such as rubber, so as to further strengthen the fixation of the extraction device.
[0061] At the same time, a slot hole is provided at the end of the clamping rod 29 , and the inner wall of the slot hole is clamped with the outer surface of the slider 261 , so that the slider 261 is limited after movement by the clamping rod 29 , thereby further limiting the slider 261 .
[0062] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.
