AI Technical Summary
Existing core drilling machines require repeated adjustments to the pusher plate positioning after sampling, which is cumbersome and affects sampling efficiency.
The design employs a pressure plate and positioning plate structure with automatic reset function. By pressing the disc, the pressure plate is moved down to loosen the core sample, and automatic reset is achieved by using a spring. Combined with the design of the positioning plate and positioning groove, the operation process is simplified.
It improves core sampling efficiency, avoids sample damage, reduces labor intensity, is suitable for continuous sampling operations, and provides a smooth and efficient sampling process.
