Description

Technical Field

[0001] The present invention relates to the technical field of underground protection, and particularly to a mechanical splash-proof shield for an underground crusher. Background Art

[0002] An underground crusher is a core device used for crushing large rocks and ores in mines, tunnels and underground projects. During the crushing operation, the high-speed rotating hammer heads or jaw plates collide violently with the materials, generating a large amount of high-speed flying crushed stones, metal debris and dust. Among various types of underground crushers, the hammer crusher is a relatively important one, and the hammer crusher mainly completes the crushing of materials by impact energy. When the hammer crusher works, the motor drives the rotor to rotate at a high speed, and the materials enter the crusher cavity evenly. The high-speed rotating hammer heads impact, shear and tear the materials to break them. At the same time, the gravity of the materials themselves causes the materials to rush from the high-speed rotating hammer heads to the baffle plate and sieve bars in the frame body. The materials larger than the sieve hole size are retained on the sieve plate and continue to be struck and ground by the hammers until they are broken to the required discharge particle size and finally discharged out of the machine through the sieve plate. During the crushing process, when hard materials are broken, the flying objects have a high speed and large kinetic energy, which may injure nearby operators or damage equipment. Therefore, as a key safety component of the underground crusher, the design and reliability of the mechanical shield are directly related to the safety of the operation environment and production efficiency.

[0003] The existing mechanical shields mostly set a hard lining structure inside the crusher, and buffer the impact force of the stones hitting the lining through the physical properties of the hard lining structure.
