The bottom end of the movable rod 62 is arranged with an inclined surface, and is inclined downward from back to front. Through this arrangement, when the movable rod 62 enters the fixed block 61, the adjusting rod 64 is pushed to move through the inclined surface. The front end surface of the adjusting rod 64 is arranged in an arc shape, and through this arrangement, it is convenient to contact with the bottom end of the movable rod 62. A protrusion is provided at the front end of the limit rod 65, and the movable range of the adjusting rod 64 is limited by this arrangement.

[0027] Here’s how it works:

[0028] First, before use, the noise reduction plate 5 is installed in the ball mill 2. The noise reduction plate 5 installed is composed of a rubber layer 51, a damping layer 52, a sound insulation layer 53 and a sound absorption layer 54. The damping layer 52 composed of asphalt slurry material can realize the refraction of sound waves on uneven surfaces, thereby reducing its sound energy and effectively reducing the sound. The sound insulation layer 53 composed of glass fiber reinforced material has a strong sound insulation effect. The sound absorption layer 54 composed of ultra-fine glass wool has countless tiny and mutually interpenetrating holes inside the sound absorption layer 54, which causes the sound waves to be subjected to friction and viscous resistance, thereby being converted into heat energy for consumption;

[0029] Second, the movable rod 62 is inserted into the fixed block 61 through the noise reduction plate 5. The movable rod 62 squeezes the right end of the adjusting rod 64 during the movement, so that the adjusting rod 64 moves along the sliding groove 63. The adjusting rod 64 squeezes the spring 66 when it moves. When the adjusting rod 64 moves into the groove of the movable rod 62, the spring 66 releases its elastic potential energy after losing its force to push the adjusting rod 64 to move. The adjusting rod 64 moves to the movable rod 62 and is fixed, so that the noise reduction plate 5 can be fixed to the fixed block 61.

[0030] Third, when the noise reduction plate 5 needs to be removed and replaced, the electromagnetic block 67 is started, and the electromagnetic block 67 generates suction on the electromagnet 68, so that the electromagnet 67 drives the adjusting rod 64 to move, and the adjusting rod 64 moves along the limiting rod 65, and at the same time squeezes the spring 66. When the adjusting rod 64 moves, the limiting effect on the movable rod 62 is cancelled, and the movable rod 62 can be taken out from the fixed block 61, and then the noise reduction plate 5 is disassembled along the supporting block 4, and the electromagnetic block 67 is turned off. After the spring 66 loses its force, it releases its elastic potential energy to push the adjusting rod 64 back to its original position, which is convenient for the next adjustment.

[0031] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0032] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
