Description

Technical Field

[0001] The utility model relates to the technical field of cement detection, in particular to a cement compressive strength detection device. Background Technique

[0002] Cement is a powdery hydraulic inorganic binder. After adding water and stirring, it becomes a slurry, which can harden in the air or in water and can firmly cement materials such as sand and stones together. The block structure composed of cement is often used in construction projects. Therefore, it is necessary to ensure the strength of the cement block. During the production and processing of the cement block, it is necessary to detect the compressive strength of the cement block, and at this time, a compressive strength detection device is required.

[0003] At present, the Chinese utility model with the publication number CN217084440U discloses a "Cement Compressive Property Detection Device", which includes a detection table. A U-shaped shield and a pressure sensor are fixedly connected to the detection table. The movable rod is driven to descend through a pressure mechanism. During the descent of the movable rod, the front of the U-shaped shield is blocked by a positive baffle, and the top of the U-shaped shield is blocked by a top plate, so that the detection environment forms a fully enclosed structure to prevent the test block from breaking and splashing and causing injury to people and objects. The movable rod continues to descend to press the cement test block through a pressing plate until the cement test block breaks. The pressure sensor is used to display and record the weight value of the applied pressure. After the detection is completed, the movable rod is raised through the pressure mechanism, and under the action of the limiting plate, the positive baffle and the top plate are pulled up, realizing the effect of automatically opening the U-shaped shield. The detected fragments are dialed into the inner part of the bottom box through a through groove for collection, preventing the influence on the detection of subsequent test blocks;

[0004] Although the above-mentioned cement compressive property detection device has certain advantages in terms of protection, by dialing the fragments into the inner part of the bottom box for collection, manual cleaning operation is required. After the cement test block breaks, fragments and dust are generated, and the dust is not easy to clean. Content of the Utility Model
