Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a mine drilling sampling device. Background Art

[0002] Mine geological sampling refers to the collection of samples from ore bodies, surrounding rocks, and mine products according to specific specifications, followed by processing and subsequent analysis, testing, or identification. Its purpose is to study mineral quality, the physical and chemical properties of the ore and surrounding rocks, the technical performance of the ore, and the mining conditions of the deposit, providing data for ore deposit evaluation, reserve calculation, and other related geology, mining, mineral processing, and comprehensive mineral utilization.

[0003] Most existing sampling devices require drilling a hole first and then transferring and storing the drilled debris as a sample. The numerous steps are very troublesome and cannot complete the sampling work quickly and efficiently.

[0004] Existing techniques for sampling open-pit mine slag piles require manual labor, such as using a shovel to dig a section out of the pile. The shovel then vertically cuts off a portion of the sample, mixes it evenly, and then uses the quartering method to collect an appropriate amount of sample into a sample bag. This process is cumbersome for a single person and often requires collaboration. This process is affected by factors such as the sampling habits of different samplers and the varying force applied to the shovel. This means that even sampling of every layer cannot be guaranteed.

[0005] The announcement number is: CN219495699U, and the name is: A mining geological sampling device, including a sampling rod, a connecting rod, a bracket, and a support rod, and also includes a clamping assembly, the upper end of the sampling rod is clamped by the clamping assembly, the clamping assembly is slidably connected to one end of the connecting rod, and a locking mechanism is provided on the connecting rod to lock the clamping assembly. The upper end of the connecting rod is provided with a driving group, which is mounted on the bracket, and the upper ends of multiple support rods are hinged on the bracket; the lower end of the sampling rod is fixedly connected to a cutting head for cutting, and the upper end of the sampling rod is fixedly connected to a fixing block, the lower end of the fixing block is provided with multiple lower slots, and the upper end of the fixing block is provided with multiple upper slots; the clamping assembly includes a lower ring and an upper column, and the lower ring is composed of two lower half rings; the utility model can drill and sample in one step, without transferring gravel, and directly collect rock strata into the sampling rod, thereby avoiding omissions and sequence errors caused by food during the transfer process. The sampling rod is clamped on it by the clamping assembly, so as to directly collect mining geological samples into the sampling rod.

[0006] Although the above-mentioned mine sampling device can complete the sampling operation quickly and efficiently, it has a complex structural design, is inconvenient to maintain, and has a short service life. Utility Model Content

The provided operating wristband can be convenient for the operator. When sampling, the operating wristband can be pressed downward to facilitate the insertion of the sampling tube body and the drill rod into the slag pile, thereby assisting the operator in the sampling operation and improving the sampling efficiency.

[0011] The side wall of the sampling tube body is provided with a square hole.

[0012] A baffle is inserted into the square hole.
