Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling device technology, and in particular to a sampling device for gold mine exploration. Background Technology
[0002] In gold mine exploration, in order to determine the content, quality, distribution and other information of gold, it is necessary to collect gold samples from different locations for analysis and testing. Existing sampling devices may be cumbersome to operate, inefficient and limited in sampling depth, making it difficult to achieve the expected exploration results. Therefore, a sampling device for gold mine exploration is needed.
[0003] Chinese patent provides a geotechnical engineering survey and sampling device, publication number CN214839834U, which includes a sampling mechanism and an installation platform. An adjustable support mechanism is fixedly connected to the bottom surface of the installation platform. The adjustable support mechanism includes a support tube. A boss is fixedly connected to the outer side of the end of the support tube away from the installation platform. A limit block is fixedly connected to the inner side wall of the bottom of the support tube. An adjustment rod is inserted into the bottom of the support tube. A limit groove is opened on the side of the adjustment rod. The limit block is inserted into the limit groove. An adjustment sleeve is provided at the bottom of the support tube. A sleeve hole is opened on the top surface of the adjustment sleeve. An annular groove is opened on the side wall of the sleeve hole. The boss is inserted into the annular groove. An adjustment hole is opened on the bottom surface of the sleeve hole.
[0004] The aforementioned sampling device allows the adjustable support mechanism to adjust its height according to the terrain, improving the stability of the surveying and sampling device and reducing the possibility of tilting or tipping over. However, during the sampling process, soil or ore fragments tend to adhere to the outer wall of the drill rod, affecting its use and thus reducing sampling efficiency. It also easily causes wear on the drill rod, affecting its service life. Utility Model Content
[0005] The main objective of this invention is to provide a sampling device for gold mine exploration, which can effectively solve the technical problem in the background art where, during the sampling process, soil or ore fragments easily adhere to the outer wall of the drill rod, affecting the use of the drill rod, thus reducing sampling efficiency and easily causing wear on the drill rod, affecting its service life.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A sampling device for gold mine exploration includes a support plate, a top plate on the top of the support plate, a connecting rod fixedly installed on the top of the top plate, a handle fixedly installed on the top of the connecting rod, four connecting strips fixedly installed on the outer wall of the support plate, one end of each of the four connecting strips being fixedly connected to the outer wall of the top plate, and a motor on the top of the support plate, the top of the motor being fixedly connected to the outer wall of the top plate.
[0008] As a further embodiment of this utility model, a drill rod is fixedly installed at the output end of the motor, a first gear is fixedly installed on the outer wall of the drill rod, and a second gear is provided on both sides of the outer wall of the first gear. The outer walls of the two second gears are rotatably connected to the outer wall of the support plate, and the second gears are meshed with the first gears.
[0009] As a further embodiment of this utility model, a telescopic rod is fixedly installed at the bottom of each of the two second gears, and a base plate is provided at the bottom of the two telescopic rods, with the top of the base plate fixedly connected to the bottom of the telescopic rod.
[0010] As a further embodiment of this utility model, the outer walls of both telescopic rods are provided with four sliding grooves, and the outer walls of the eight sliding grooves are provided with connecting blocks, and the outer walls of the connecting blocks are slidably connected to the sliding grooves.
[0011] As a further embodiment of this utility model, each of the two telescopic rods is provided with a connecting ring at its bottom, and the connecting ring is fixedly connected to the outer wall of the connecting block.
[0012] As a further embodiment of this utility model, cleaning brushes are fixedly installed on the outer walls of the two connecting rings, and the cleaning brushes are located on both sides of the drill rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1) This gold mine exploration sampling device can drive the drill rod to rotate through the output end of the motor. When the worker holds the handle and presses down on the top plate of the sampling device, the rotating drill rod will gradually pass through the hole in the bottom plate as the worker presses down. Through the meshing connection between the second gear and the first gear, the rotation of the first gear can drive the rotation of the second gear. Since the connecting block is restricted in the sliding groove, when the second gear drives the telescopic rod to rotate, it will also cause the connecting ring connected to the connecting block to rotate. At the same time, the rotation of the connecting ring drives the cleaning brush to clean the outer wall of the drill rod, thereby preventing soil or ore fragments from adhering to the outer wall of the drill rod during the sampling process and affecting the use of the drill rod.
[0015] 2) When the support plate is pressed down and the telescopic rod is retracted, the connecting block can slide along the outer wall of the sliding groove of this gold mine exploration sampling device. This ensures that the cleaning brush can always be in close contact with both sides of the drill rod, effectively removing the mud and ore debris attached to the drill rod, avoiding pollution and interference during the sampling process. Furthermore, the drill rod is confined inside, which can prevent the drill rod from shifting or shaking during the sampling process, ensuring that the drill rod can carry out sampling work stably. It can also effectively protect the drill rod from interference and damage from the external environment, extending its service life. Attached Figure Description

[0026] Example 2
[0027] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the outer walls of both telescopic rods 10 are provided with four sliding grooves 12, and the outer walls of the eight sliding grooves 12 are provided with connecting blocks 13. The outer walls of the connecting blocks 13 are slidably connected to the sliding grooves 12.
