DETAILED DESCRIPTION

[0017] Reference Figure 1-5 The vibration-damping wall protection structure comprises a wall protection body 1, a protective plate 2 is provided on the outer periphery of the wall protection body 1, the upper end of the protective plate 2 and the upper end of the wall protection body 1 are fixedly connected by an upper connecting plate 3, symmetrical L-shaped card plates 4 are fixedly connected on both sides of the upper end of the upper connecting plate 3, the lower end of the protective plate 2 and the lower end of the wall protection body 1 are fixedly connected by a lower connecting plate 6, a symmetrical fixing groove 7 is fixedly connected to the inner lower end of the wall protection body 1, the fixing groove 7 and the L-shaped card plate 4 are located on the same side of the wall protection body 1, a symmetrical second return spring 8 is provided inside the fixing groove 7, a symmetrical clamping block 9 is slidably connected to the lower end of the wall protection body 1, a connecting rod 91 passing through the fixing groove 7 is fixedly connected to the middle part of one end of the clamping block 9 close to the second return spring 8, the other end of the connecting rod 91 is fixedly connected to a limiting plate 92, and a push-pull plate 93 is fixedly connected to the middle part of the upper end of the limiting plate 92.

[0018] Furthermore, a symmetrical slide groove 61 is provided on the lower connecting plate 6, and the slide groove 61 is located directly below the L-shaped card plate 4, and the length and width of the slide groove 61 are equal to the length and width of the upper end of the L-shaped card plate 4. It is convenient for the L-shaped card plate 4 to pass through the lower connecting plate 6 and the card block 9 to realize the card connection.

[0019] Furthermore, a stopper 10 is inserted into the chute 61. The stopper 10 does not need to be removed from the bottom of the protective wall body 1 to prevent the ore from entering between the protective wall body 1 and the protective plate 2 from the chute 61.

[0020] Furthermore, a plurality of first return springs 5 ​​are provided between the wall protection body 1 and the protection plate 2 to enhance the vibration reduction effect of the wall protection.

[0021] Furthermore, the card block 9 is located directly below the L-shaped card plate 4, and a slope is provided at the lower end of the card block 9, so that the L-shaped card plate 4 can slide along the slope of the card block 9 to the upper end of the card block 9, thereby achieving the card connection.

[0022] When the device is used, first align the slide groove 61 on one guard wall with the L-shaped card plate 4 of the other guard wall according to the required guard wall height, and then move them closer. The L-shaped card plate 4 will slide along the slide groove 61 to the inclined surface of the block 9. At this time, the second return spring 8 will be compressed until the L-shaped card plate 4 is located at the upper end of the block 9. The second return spring 8 restores its elasticity and restores the block 9 to its original position, so that the L-shaped card plate 4 is located at the upper end of the block 9 to achieve the snap connection until it is connected to the required height. If the two guard walls need to be disassembled, it is only necessary to pull the push-pull plate 93 and then separate the two guard walls. The first return spring 5 between the guard wall body 1 and the protection plate 2 enhances the vibration reduction effect of the guard wall. At the same time, the snap connection method of superimposing the guard walls improves the firmness and safety of the guard walls.
