[0041] The present utility model will be further described below with reference to the drawings.

[0042] Oil logging is an important technology in the process of oil drilling. It observes, collects, records, and analyzes the information of the wellbore returns such as solids, liquids, and gases during the drilling process, establishes a logging geological profile, discovers oil and gas shows, evaluates oil and gas layers, and provides drilling information services for petroleum engineering. In the existing oil logging site, rock thin sections are made by a grinding machine. Through the optical properties of the rock thin sections, the rock type and its genetic characteristics are determined, and finally the name of the rock is determined. This is an important method often used in oil and gas exploration work in petroleum geology. However, the dust and debris generated during the grinding process of the existing grinding machine are easy to fly everywhere, affecting the working environment and posing a safety hazard.

[0043] As Figure 1 shown, to solve the above technical problems, at least one embodiment of the present utility model provides a rock thin section grinding device, which includes a machine body 10, a grinding box 20, a transmission component 30, and two shielding components 40; the grinding box 20 is arranged on the machine body 10, and the top of the grinding box 20 has an opening; the transmission component 30 is arranged on the machine body 10 and is located above the grinding box 20; the two shielding components 40 are rotatably arranged on the machine body 10, and the two shielding components 40 are respectively located on both sides of the transmission component 30 and are connected to the transmission component 30; wherein, the transmission component 30 can drive the two shielding components 40 to rotate in opposite directions so that the shielding components 40 shield the opening.

[0044] As can be seen from the above, by setting the shielding component 40 that can shield the opening of the grinding box 20, it plays a role of shielding and protection, avoiding the dust and debris generated during the grinding of the rock in the grinding box 20 from flying, thereby improving the working environment at the oil logging site and ensuring the safety of the staff; in addition, by setting the two shielding components 40, not only the shielding area of the opening is ensured, but also the installation position of the transmission component 30 is reserved. At the same time, by using the transmission component 30 to drive the two shielding components 40 to rotate in opposite directions, the included angle between the shielding component 40 and the grinding box 20 can be changed, so as to effectively adjust the shielding area of the shielding component 40, improving flexibility and practicability.

For example, the grinding component includes a grinding motor and a grinding wheel disc surface, and the grinding motor drives the grinding wheel disc surface to rotate, and the grinding wheel disc surface grinds the rock.

[0046] It should also be noted that the drive assembly 30 drives the shielding assembly 40 to rotate, which can change the angle between the shielding assembly 40 and the grinding box 20; when the angle between the shielding assembly 40 and the grinding box 20 is 0, the shielding area of the shielding assembly 40 for the opening is the largest: when the angle between the shielding assembly 40 and the grinding box 20 is larger, the shielding area of the shielding assembly 40 for the opening is smaller.

[0047] It should also be noted that the drive assembly 30 can drive the two shielding assemblies 40 to rotate in opposite directions, that is, when one shielding assembly 40 rotates clockwise, the other shielding assembly 40 rotates counterclockwise.

[0048] As Figure 1 shown, the rock thin section grinding device includes a machine body 10, a grinding box 20, a drive assembly 30 and two shielding assemblies 40; the grinding box 20 is arranged on the machine body 10, and the top of the grinding box 20 has an opening; the drive assembly 30 is arranged on the machine body 10 and above the grinding box 20; the two shielding assemblies 40 are rotatably arranged on the machine body 10, and the two shielding assemblies 40 are respectively located on both sides of the drive assembly 30 and connected to the drive assembly 30; wherein, the drive assembly 30 can drive the two shielding assemblies 40 to rotate in opposite directions so that the shielding assembly 40 shields the opening.

[0049] By providing the shielding assembly 40 that can shield the opening of the grinding box 20, it plays a role of shielding and protection, avoiding the dust and debris generated during the grinding of the rock in the grinding box 20 from splashing, thereby improving the working environment at the oil logging site and ensuring the safety of the staff; in addition, by providing the two shielding assemblies 40, not only the shielding area for the opening is ensured, but also the installation position of the drive assembly 30 is reserved. At the same time, by using the drive assembly 30 to drive the two shielding assemblies 40 to rotate in opposite directions, the angle between the shielding assembly 40 and the grinding box 20 can be changed, so as to effectively adjust the shielding area of the shielding assembly 40, improving flexibility and practicality.

[0050] It should be noted that the rock thin section grinding device further includes a grinding assembly arranged in the grinding box 20. The grinding assembly is used to grind the rock. By arranging the grinding assembly in the grinding box 20, it is avoided that the grinding assembly is directly exposed outside, and the dust and debris generated during the grinding process are collected in the grinding box 20 as much as possible; the specific structure and working principle of the grinding assembly are both prior arts and will not be elaborated in this application. For example, the grinding assembly includes a grinding motor and a grinding wheel disc surface, and the grinding motor drives the grinding wheel disc surface to rotate to grind the rock.

[0051] It should also be noted that the drive assembly 30 drives the shielding assembly 40 to rotate, which can change the angle between the shielding assembly 40 and the grinding box 20; when the angle between the shielding assembly 40 and the grinding box 20 is 0, the shielding area of the shielding assembly 40 for the opening is the largest: when the angle between the shielding assembly 40 and the grinding box 20 is larger, the shielding area of the shielding assembly 40 for the opening is smaller.

[0052] It should also be noted that the drive assembly 30 can drive the two shielding assemblies 40 to rotate in opposite directions, that is, when one shielding assembly 40 rotates clockwise, the other shielding assembly 40 rotates counterclockwise.

[0053] In one embodiment, the shielding assembly 40 includes a baffle 410, and the baffle 410 is rotatably arranged on the machine body 10; wherein, the drive assembly 30 can drive the baffle 410 to rotate so that the baffle 410 shields the opening.

[0059] By setting the transmission part to drive the lifting part 330 to lift and lower, the sliding column 340 rises and falls with the lifting part 330. At the same time, the sliding column 340 slides in the transition groove 440, driving the transition rod 430 to rotate, and the baffle 410 rotates with the transition rod 430, thereby realizing the rotation of the baffle 410 to block the opening of the grinding box 20.
