[0040] Working principle:

[0041] The first step is to place the test piece on the conveyor belt 18 on one side of the transmission roller 12 when the unconfined compressive strength tester with convenient demoulding is used, and then start the servo motor 19. The output shaft of the servo motor 19 rotates to drive the transmission roller 2 13 to rotate, and the transmission roller 2 13 rotates to drive the conveyor belt 18. The conveyor belt 18 is forced to drive the transmission roller 3 16 to rotate, and the transmission belt 18 is forced to drive the transmission roller 4 17 to rotate. The transmission belt 18 is forced to drive the transmission roller 12 to rotate, and the transmission rollers 12, 13, 3 16 and 4 17 rotate to drive the conveyor belt 18 to transport the test piece. When the conveyor belt 18 drives the test piece When it reaches the unloading table 25, the test piece is pushed to be placed on the upper end of the support table 24, and then the hydraulic rod 2 is started. The telescopic rod of the hydraulic rod 2 drives the load-bearing plate 21 to move downward, and the load-bearing plate 21 is forced to drive the pressure sensor 22 and the upper pressure plate 23. The upper pressure plate 23 moves downward to squeeze the test piece, and the pressure sensor 22 monitors the pressure value and transmits the data to the display screen 26. By adding a conveyor belt 18 to the unconfined compressive strength testing machine that is easy to demold, the conveyor belt 18 can transport the test piece during the compressive strength test of the test piece, thereby reducing the labor intensity of handling the test piece and effectively improving the portability of the unconfined compressive strength testing machine.

[0042] In the second step, when the unconfined compressive strength testing machine with convenient demoulding is used, after the specimen monitoring is completed, the specimen is pushed, and the specimen slides from the unloading platform 25 on the side of the support platform 24 to the conveyor belt 18, and then the rotating conveyor belt 18 conveys the specimen. When the specimen is conveyed from the conveyor belt 18 on the side of the transmission roller three 16 to the side of the transmission roller two 13, the specimen slides from the side of the transmission roller two 13, and the servo motor 19 is turned off. By adding the conveyor belt 18 to the unconfined compressive strength testing machine with convenient demoulding, the conveyor belt 18 can transport the specimen downward during the compressive strength test of the specimen, thereby effectively improving the practicality of the unconfined compressive strength testing machine.
