[0034] A hydraulic cutter device 4, a hot and cold seam making device 5 and a cleaning tank 7 are sequentially arranged above the straight side of the core sample making component 1 close to the regular sample input belt 2 from the regular sample input belt 2 to the grouting simulation component 11, and a dripping mechanical arm 6 is arranged between the hot and cold seam making device 5 and the cleaning tank 7, and the dripping mechanical arm 6 is arranged outside the core sample making component 1, and the dripping mechanical arm 6 is connected to a chemical solvent tank 12;

[0035] The core sample preparation component 1 is provided with a high temperature vaporization chamber 10 and a cleaning tank 7 in sequence from the rock sample mixer 3 to the grouting simulation component 11 on the straight side near the rock sample mixer 3. The high temperature vaporization chamber 10 and the rock sample mixer 3 are provided with two sets of display racks 8. The two sets of display racks 8 are arranged outside the core sample preparation component 1, and a clamping and inserting mechanical arm 9 is arranged between the two sets of display racks 8.

[0036] As a preferred embodiment, the device needs to determine the state of the core sample in advance. If there is a complete core sample, it will be cut and trimmed into a rectangular parallelepiped with a flat side and meeting the requirements. If there is no complete core sample, the mortar material that meets the requirements is injected into the core sample preparation component 1 for molding and production, so that the device can meet the production of core samples under different conditions, and thus better perform simulation experiments. Because the width, length, depth, direction and inclination of the core cracks can affect the penetration and diffusion of the slurry, thereby affecting the experimental results, the device is equipped with a hydraulic cutter device 4, a hot and cold seam making device 5, a dripping mechanical arm 6 and a chemical solvent tank 12, a display rack 8 and a clamping and inserting machine. The mechanical arm 9 and the high-temperature vaporization chamber 10 are used to manufacture different cracks, thereby simulating the actual rock crack conditions to the greatest extent and improving the authenticity and accuracy of the experimental simulation. At the same time, the setting of the core sample making component 1 can carry the core sample and adjust the position of the core sample to make the crack. After the crack is made, the grouting simulation component 11 is used to perform experimental simulation. After the simulation is completed, the core sample making component 1 is cleaned by the corresponding cleaning tank 7 so that it can continue to participate in subsequent work.
