[0002] In the field of gravel, pressure testing is mainly used to evaluate the compressive strength index value of gravel. Compressive strength refers to the maximum pressure that a material can withstand when subjected to pressure perpendicular to its surface. The compressive strength index value of gravel is usually obtained through experimental measurement, among which pressure testing machine is a commonly used experimental equipment. When conducting a pressure test, you first need to place a certain number of gravel samples under the pressure of the testing machine, and then gradually increase the pressure and record the corresponding gravel compressive strength value.

[0003] The existing pressure testing machine consists of a mounting frame, a control box, a hydraulic cylinder, a pressure block and a pressure measuring platform. When working, the bricks are placed on the upper side of the pressure measuring platform installed inside the mounting frame, and the control box controls the hydraulic cylinder to drive the pressure block to squeeze the bricks to test their pressure resistance. However, the existing pressure testing machine uses a single baffle to prevent splashing, which cannot cushion the splashing gravel, causing the baffle to be easily damaged and need to be replaced regularly.
