A slot 19 is opened on the ring wall of the cooling seat 4, and the air intake holes 5 are located in the slot 19. A dustproof sponge 20 is sleeved in the slot 19 to prevent dust from entering the cooling seat 4 through the air intake holes 5.
[0031] The connecting pipe 6 is a hollow cylindrical structure with an opening at the bottom. The connecting pipe 6 is installed through the top of the cooling base 4, and the top of the connecting pipe 6 is connected to the output end of the motor 3. Several exhaust holes 7 are opened through the annular wall of the connecting pipe 6. The gas in the cooling base 4 flows into the connecting pipe 6 and is discharged through the exhaust holes 7. At the same time, the motor 3 controls the rotation of the connecting pipe 6, and the connecting pipe 6 drives the cooling base 4 to rotate.
[0032] The flow guide plate 8, there are several flow guide plates 8, which are fixed at equal angles on the inner wall of the cooling seat 4. By rotating the flow guide plate 8, it is easy to control the flow of gas inside the cooling seat 4 into the connecting pipe 6.
[0033] The grinding disc 9 has several cooling rods 10 fixedly installed on its top surface. The cooling rods 10 are movably inserted into the bottom surface of the cooling seat 4. The grinding disc 9 and the cooling seat 4 are in contact with each other. The heat conduction of the cooling rods 10, combined with the flow of air, facilitates the cooling of the grinding disc 9 and prevents the grinding disc 9 from overheating and damaging the composition of the core sample. The ring wall of the grinding disc 9 is provided with a groove 21. A sealing ring 22 is movably fitted in the groove 21. The sealing ring 22 is in contact with the cooling seat 4 and improves the sealing between the cooling seat 4 and the grinding disc 9.
[0034] A connecting component 11 is disposed on the annular wall of the cooling base 4 and is connected to the grinding disc 9. The connecting component 11 includes:
[0035] Connecting block 12, there are several connecting blocks 12, and the several connecting blocks 12 are fixedly arranged at equal angles on the annular wall of the cooling seat 4. The connecting blocks 12 play a positioning role.
[0036] Connecting ring 13, there are several connecting rings 13, which are screwed onto the ring wall of the grinding seat 2 by a hinge seat, and the connecting rings 13 are movably locked on the connecting block 12. By locking the connecting rings 13 on the connecting block 12, it is easy to fix the position of the grinding disc 9.
[0037] Limiting plate 14, there are several limiting plates 14, one end of each limiting plate 14 is screwed onto the connecting block 12 by a hinge seat, and the limiting plate 14 and the connecting ring 13 are engaged and abutted, and the connecting ring 13 is restricted to the connecting block 12 by the rotation of the limiting plate 14.
[0038] A plurality of connecting screws 15 are threaded onto the side of the connecting block 12, and the ends of the connecting screws 15 are engaged with the ends of the limiting plates 14 to abut against each other. The connecting screws 15 are used to fix the tilt angle of the limiting plates 14. The ends of the connecting screws 15 are fixed with protrusions 16, and the protrusions 16 are provided with anti-collision pads 17. The protrusions 16 are used to drive the connecting screws 15 to rotate. The bottom surfaces of the limiting plates 14 are provided with protective pads 18, which are engaged with the ends of the connecting screws 15 to abut against each other to prevent the ends of the connecting screws 15 from damaging the limiting plates 14.
[0039] When using this utility model, the operator places the core sample block in the grinding seat 2, raises the grinding seat 2 using an external drive, so that the grinding disc 9 contacts the core sample block, and then starts the motor 3. The motor 3 drives the connecting pipe 6 to rotate, the connecting pipe 6 drives the cooling seat 4 to rotate, and the cooling seat 4 drives the grinding disc 9 to rotate, thereby grinding the core sample. When the cooling seat 4 rotates, it drives the guide plate 8 to rotate, and the guide plate 8 allows the air in the cooling seat 4 to flow into the connecting pipe 6, and then to be discharged from the exhaust hole 7. This allows the external air to enter the cooling seat 4 through the dustproof sponge 20 and the air intake hole 5, thereby forming a flowing circulating gas in the cooling seat 4. The flowing gas is used to cool and dissipate heat from the cooling rod 10, and the heat conduction effect of the cooling rod 10 is used to cool the grinding disc 9, so as to prevent the grinding disc 9 from being damaged by excessive temperature.
[0040] When the operator replaces the grinding disc 9, the connecting screw 15 is loosened by the protrusion 16, so that the end of the connecting screw 15 is separated from the limiting plate 14, so that the tilted limiting plate 14 is restored to a horizontal state. Then the connecting ring 13 is rotated so that the connecting ring 13 is disengaged from the connecting block 12. Finally, the grinding disc 9 is removed for replacement.
[0041] Compared with the prior art, the beneficial effects of this utility model are:
[0042] 1. The cooling seat 4 drives the flow plate 8 to rotate, and with the air intake hole 5 and exhaust hole 7, the air can circulate in the cooling seat 4, thereby cooling the cooling rod 10 and then the grinding disc 9, so as to prevent the grinding disc 9 from being too hot and damaging the composition of the rock core sample.
[0043] 2. Set up the connecting component 11, and use the connecting screw 15 to control the tilt of the limiting plate 14, so as to restrict the connecting ring 13 on the connecting block 12, thereby fixing the grinding disc 9 on the bottom surface of the cooling seat 4.
[0044] 3. Install a dustproof sponge 20 to prevent dust from clogging the air intake 5 and affecting the cooling of the grinding disc 9;
[0045] 4. A sealing ring 22 is provided to make the cooling seat 4 and the grinding disc 9 flexibly connected, while improving the sealing between the cooling seat 4 and the grinding disc 9.
