Description

Technical Field

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

[0002] In the mining process, rock sampling is a key link in evaluating the distribution of mineral deposits, rock stability and mining safety. Therefore, the accuracy of rock sampling is directly related to the evaluation results of mineral distribution. By collecting representative rock samples from different depths and locations, geologists can analyze the precise location, shape and reserves of the ore body. These data provide a scientific basis for formulating reasonable mining plans to ensure the maximum utilization of resources and the optimization of economic benefits.

[0003] Traditional sampling methods mainly rely on simple manually operated tools, such as shovels and drills. These tools are suitable for small-scale or preliminary sample collection. However, in large-scale mining operations, traditional methods require a lot of manpower input, which is not only inefficient, but may also lead to insufficient sample representativeness due to improper operation or equipment limitations, thereby affecting the accuracy of subsequent analysis results. Therefore, it is necessary to improve traditional sampling tools and design a sampling device for mining. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0020] A sampling device for mining, such as Figure 1-Figure 4 As shown, it includes a sampling tube 1 and a drill bit 2. The sampling tube 1 is the main body of the sampling device. A plurality of sampling through grooves are arranged at intervals on the tube wall of the sampling tube 1. The drill bit 2 is mounted on the body of the sampling tube 1. The drill bit 2 is used to drill into the rock formation of the mine for sampling. It also includes a gear ring 6, a motor 7, a gear 71, a mounting plate 8 and a bearing 81. The outer wall of the tube of the sampling tube 1 is fixed with a gear ring 6. The sampling tube 1 is integrally arranged on the mounting plate 8. The mounting plate 8 is provided with a bearing 81. The sampling tube 1 is rotatably mounted on the mounting plate 8 through the bearing 81. The mounting plate 8 A motor 7 is fixedly installed on the upper part, and a gear 71 is fixedly arranged on the output shaft of the motor 7. The gear 71 and the gear ring 6 on the outer wall of the sampling tube 1 are meshed with each other. The interior of the sampling tube 1 is a hollow cylinder, and a blocking member is arranged inside the sampling tube 1. The blocking member is used to adjust the sampling groove on the sampling tube 1, so that after the sampling tube 1 is drilled into the rock formation of the mine through the drill bit 2, the sampled rock and soil can enter the cylinder body of the sampling tube 1 through the sampling groove, and then the sampling groove of the sampling tube 1 is blocked and closed by the blocking member, so that the sampling tube 1 can completely take out the sampled rock and soil, thereby improving the sampling efficiency.

[0021] like Figure 2 and Figure 3 As shown, a shell 9 is fixedly installed on the top surface of the mounting plate 8, and the shell 9 covers the mechanical structure of the gear ring 6 and the gear 71. A handle 10 is fixedly provided on the top of the shell 9, and a handle 2 11 is also fixedly provided in the middle of the shell 9. The user can stably operate the device to perform drilling sampling operations on the rock strata of the mine by holding the handle 10 and the handle 2 11.

[0022] like Figure 3 and Figure 4 As shown, the blocking member includes a blocking cylinder 4 and an electric push rod 5. The blocking cylinder 4 is slidably sleeved inside the sampling cylinder 1. The length of the blocking cylinder 4 is smaller than that of the sampling cylinder 1. A slot adapted to the sampling slot of the sampling cylinder 1 is opened on the cylinder body of the blocking cylinder 4. An electric push rod 5 is fixedly installed in the cylinder body at the rear end of the sampling cylinder 1. The push rod of the electric push rod 5 is connected to the blocking cylinder 4. When the slot of the blocking cylinder 4 is aligned with the sampling slot adapted to the sampling cylinder 1, the rock and soil in the rock formation can enter the sampling cylinder 1. When the sampling time of the sampling cylinder 1 in the rock formation reaches a preset value, the electric push rod 5 drives the cylinder body of the blocking cylinder 4 to block the sampling slot of the sampling cylinder 1, so that the sampled rock and soil are retained in the sampling cylinder 1 to prevent soil from overflowing when the sampling cylinder 1 withdraws from the rock formation.

[0023] like Figure 2 and Figure 4 As shown, the drill bit 2 is a bolt-type detachable assembly on the front end body of the sampling tube 1. The drill bit 2 is symmetrically provided with no less than two tightening grooves 21, and the tightening grooves 21 of the drill bit 2 are for the fixing bolts 3 to be screwed into. A docking hole 31 adapted to the tightening grooves 21 is provided on the front end body of the sampling tube 1. The drill bit 2 is tightened on the sampling tube 1 through the fixing bolts 3, and it is convenient to disassemble and maintain the drill bit 2 from the sampling tube 1.

[0024] like Figure 1 As shown, a protective plate 12 is also included. The protective plate 12 is arranged between the outer shell 9 and the sampling tube 1. The protective plate 12 is assembled on the outer shell 9 by bolts. The protective plate 12 blocks the front side of the outer shell 9. The protective plate 12 is used to protect the user who operates on the outer shell 9; an observation panel 13 is arranged on the protective plate 12. The observation panel 13 is made of tempered glass. The observation panel 13 facilitates the user to observe the drilling and sampling of the sampling tube 1 and the drill bit 2 at the rear side of the protective plate 12.

[0025] When using the sampling device to take samples at the rock formation in a mine, the user first holds the handle 10 and the handle 2 11 on the shell 9, and stably aligns the device with the target position of the rock formation in the mine. After starting the motor 7, the motor 7 drives the gear 71 to mesh with the gear ring 6 on the outer wall of the sampling tube 1, and drives the sampling tube 1 to rotate at high speed on the mounting plate 8 through the bearing 81, driving the drill bit 2 at the front end of the sampling tube 1 to cut into the rock formation. As the sampling tube 1 goes deeper, the multiple sampling grooves on the tube wall are gradually exposed to the inside of the rock formation. At this time, the blocking tube 4 in the blocking member maintains the initial position through the electric push rod 5, so that the slot of the blocking tube 4 is aligned with the sampling groove, and the rock and soil enter the hollow cavity of the sampling tube 1 through the groove. When the preset sampling time is reached, the electric push rod 5 is controlled to retract and retract. The movable push rod 5 drives the retaining tube 4 to slide along the inner wall of the sampling tube 1 until the solid part of the retaining tube 4 completely covers the sampling groove to form a closed structure to prevent the rock and soil from retreating or overflowing. Then the motor 7 is turned off, and the entire sampling device is taken out from the borehole to separate the drill bit 2 from the rock formation. During this process, the tempered glass observation panel 13 on the front side of the protective plate 12 allows the user to monitor the drilling and sampling status in real time, and the design of the outer shell 9 and the protective plate 12 effectively isolates the mechanical parts and debris to ensure safe operation. After the sampling is completed, the detachable drill bit 2 is removed from the front end of the sampling tube 1 through the fixing bolt 3 for easy cleaning or replacement. Finally, the retaining tube 4 is reset by the electric push rod 5 to open the sampling groove again, and the complete rock and soil sample in the cavity of the sampling tube 1 can be taken out.
