[0002] Concrete test blocks are standardized specimens made from concrete as the test block material and through a specific preparation and curing process. Concrete test block compression tests are mainly used to test various properties of concrete, such as strength, density, water-cement ratio, and fluidity, in order to ensure building quality, ensure project safety, and improve the service life of buildings.

[0003] For example, a Chinese patent discloses a concrete strength testing device for construction projects (publication number: CN220794830U). Through the setting of protective and fixing mechanisms, it greatly reduces the safety problems caused by splashing during the concrete test block pressure test, and has high practicality.

[0004] However, during the use of this strength testing device, it was found that the concrete waste generated during the pressure test needed to be cleaned up before the next concrete test block could be tested. Cleaning up the waste on the operating table was quite troublesome, which affected the efficiency of the pressure test and was also not conducive to the storage and subsequent processing in the laboratory.

The electric cylinder 14 drives the pressure plate 15 downward. After the test block is crushed, the electric cylinder 14 drives the pressure plate 15 upward. Both springs 403 simultaneously drive the clamping block 404 and the sliding rod 402 to move towards the center of the support plate 2 5, pushing the concrete waste towards the support. Multiple material discharge holes 501 at the center of plate 2 5, when used with a cleaning brush, can quickly clean the operating table and improve the efficiency of pressure testing. Concrete waste enters the crushing box 6 through the material discharge holes 501. After crushing and grinding the waste by crushing roller 1 17 and crushing roller 2 18, it flows out from the discharge port 601 through guide plate 1 20 and guide plate 2 21, which is convenient for laboratory stacking and processing.
