Description

Technical Field

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

[0002] Ore sampling refers to the process of taking ore samples from various parts of the ore body at certain intervals and using appropriate methods in geological exploration to understand the quality and changes of ore in a certain deposit. The samples are mainly used for analysis, identification or technical testing to determine the ore grade and the content of harmful impurities. There are many sampling methods, the most common being block sampling and groove sampling. In the process of base sampling, base sampling equipment is usually required.

[0003] Publication No. CN222393820U discloses a geological sampling device for mines. A sleeve is placed in the area to be sampled. A first motor drives a rotating shaft to rotate, which in turn drives a spiral drill rod to drill into the target area. After drilling, a second motor rotates clockwise, causing the spiral drill rod to carry out the geological sample from the borehole. Before the sample enters the collection box, it needs to pass through a rotating plate. A second motor drives the rotating plate to rotate, thereby moving different filters to the contact point with the collection box, allowing for multi-stage sieving of the sample. However, this patent still has the following problems in practical use:

[0004] Although the mining geological sampling device uses a first motor to drive a rotating shaft, which in turn drives a spiral drill rod to drill into the target area, it is not easy to fix the entire device during drilling. This results in instability of the device, especially when drilling into harder mineral geology, where the vibration force is greater, affecting the efficiency of the device's drilling and sampling.

[0005] Therefore, a geological sampling device for mines is proposed to solve the problems mentioned above. Utility Model Content

[0033] Working principle: Before using this type of mine geological sampling device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6As shown, firstly, the first adjusting knob 103 drives the adjusting bidirectional threaded rod 104 to rotate, causing the first adjusting threaded sleeve 105 to move the second adjusting bracket 106 relative to one side of the first adjusting bracket 101. Simultaneously, rotating the second adjusting knob 107 drives the second adjusting threaded rod 108 to rotate, causing the second adjusting threaded sleeve 109 to move the first lifting threaded adjusting column 110, thus adjusting the position of the supporting base plate 111. The first lifting threaded adjusting column 110 and the second lifting adjusting threaded column 112 are composed of a threaded sleeve and a threaded rod, respectively. The movable threaded rod allows for height adjustment, thus adapting to uneven geological sampling conditions in mines. Secondly, adjusting the second lifting adjustment threaded column 112 allows for adjustment of the distance between the support base plate 111 and the opening / closing bracket 113. Under the action of the opening / closing rotating rod 119, the opening / closing sliding sleeve 115 drives the opening / closing support leg 116 to unfold or close. The entire fixing mechanism 1 is fixed by the threaded fixing pin 117, improving the stability of the fixing mechanism 1 and facilitating geological sampling in mines. Starting the lifting motor 122 drives the sprocket transmission assembly 123. The lifting threaded rod 124 rotates, causing the lifting threaded sleeve 125 to move the mounting plate 126 and the sampling conveying pipe 201 up and down, thereby sampling the mine geology. Finally, the conveying motor 202 drives the conveying auger 203 to rotate the industrial sampling drill bit 204. The sampling drill bit 204 can crush the mine geology, and the conveying auger 203 can transport the crushed sample. Under the action of the connecting pipe 211, the sample enters the screening cylinder 212. The screening motor 213 is started to drive the screening rotating rod 214 and the screening stirring support. The 215 rotates, and the sieving stirring support 215 can stir the sample and the sieving screen 217 can sieve the sample. The sieving screen 217 can be removed from the bottom of the sieving cylinder 212 by the mounting sleeve 216, which is convenient for cleaning the sample. The switching motor 207 is started to drive the switching worm 208 to rotate. Utilizing the meshing connection between the switching worm 208 and the switching worm wheel 209, the switching worm wheel 209 drives the switching sleeve 210, the connecting pipe 211 and the sieving cylinder 212 to rotate, thereby realizing uninterrupted sample sieving.
