The invention discloses an automatic load applying device for concrete experiment testing equipment, relates to the technical field of concrete testing, and aims at the compressive strength testing process of a concrete precast block, adopts a superposed two-punching experiment testing mode, and is essentially established in the way that a hydraulic bed and other structures are used for applying pressure to increase the concrete load so as to reach the damage degree. The implementation process is different in that when a certain value of load is applied, the instant impact force is applied again, the purpose of the instant impact force is to simulate specific parameters of the concrete precast block when the concrete precast block faces varied use environment factors, the whole test process is carried out based on a hydraulic structure, a motion control mode on a system is adopted, and the test accuracy is improved. And a multi-gradient superposition secondary punching motion stage is carried out on the direc
