One end of the pressure rod 203 is fixedly connected to a baffle 204, and the pressure rod 203 is against the movable plate 13.

[0028] In the present application, the pressure rod 203 is pressed on the movable plate 13, the pressure rod 203 is located at the bottom of the pressure plate, the movable plate 13 compresses the spring 15, and makes the fixed plate 12 and the slider 10 at the lowest position, the gravity ball 5 is pulled by the traction rope 6 and is at the highest position, the traction rope 6 is pressed tightly on the two pulleys 8, when the test is carried out, the building material to be tested is placed on the test platform 1, so that the building material is located in the protection frame 4, when the motor 205 is started, the motor 205 drives the turntable 202 to rotate, so that the pressure rod 203 moves along the Figure 1As shown in the clockwise rotation, the movable plate 13 and the fixed plate 12 are separated from the contact with the pressure plate, and the slider 10 slides upward along the guide rail 11 under the gravity of the gravity ball 5, and the gravity ball 5 impacts the building material downward.

[0037] In summary, the building material impact detection device drives the turntable 202 to rotate through the motor 205, so that the pressure rod 203 rotates clockwise, the movable plate 13 and the fixed plate 12 are separated from the contact with the pressure plate, and the slider 10 slides upward along the guide rail 11 under the gravity of the gravity ball 5, and the gravity ball 5 impacts the building material downward. As the turntable 202 rotates, the pressure rod 203 contacts the movable plate 13 again, and the movable plate 13 and the fixed plate 12 are pressed downward by the pressure rod 203, so as to drive the slider 10 to move downward, thereby driving the gravity ball 5 to move upward, realizing continuous impact operation, and evaluating the impact resistance of the material according to the number of impacts and the damage of the material, by arranging the movable plate 13 on the fixed plate 12, so that the pressure rod 203 contacts the movable plate 13, and when the movable plate 13 is pressed down, the spring 15 contracts, and the movable plate 1 3 moves in the direction close to the fixed plate 12, the spring 15 plays a certain buffering role on the movable plate 13, which can reduce the impact force brought by the pressure rod 203, reduce noise, and avoid damage between components due to severe collision, thereby extending the service life of the components. By arranging rollers 17 at both ends of the protective plate 16, it is possible to avoid wear of the traction rope 6 and both ends of the protective plate 16. By arranging the protective plate 16 and the side plate 9, it is possible to avoid the traction rope 6 from accidentally falling off the pulley 8, thereby improving the safety of the detection. After the detection is completed, the protective frame 4 is driven by the electric push rod 306 to move outward. During the process of the protective frame 4 moving out of the detection table 1, the debris will be scraped from the detection table 1 into the waste box, thereby realizing automatic cleaning of the debris. By arranging the protective frame 4, the debris can be blocked to avoid splashing out and causing damage to the staff.
