AI Technical Summary
Existing flexible shock absorption devices for crushers are less effective at reducing amplitude under large vibration impacts, and cannot effectively protect the equipment.
The system employs a buffer ring and a buffer solution made of shear-thickening fluid material, combined with a rubber encapsulation sleeve. This reduces amplitude through multi-directional deformation and increased viscosity, while the combination of a steel threaded sleeve and a rubber separator improves connection stability.
Under strong vibration and impact, the shearing effect of the buffer ring is enhanced, protecting the main body of the crusher, extending the service life of the equipment, and reducing damage to parts.

[0002] The ore of mining operation initial mining is usually very big and uneven in size, and inconvenient for transportation and subsequent production, so it is required to use the crusher to break the big ore, so that the ore forms the form of uniform particle size and small volume. In order to meet the crushing requirement, the crusher is required to have great power and strong crushing force, which leads to that the crusher is easy to produce relatively strong vibration, and when the equipment vibration is too large, the production efficiency of the crusher is affected, the parts are damaged, and the service life is reduced, so the damping measures need to be adopted.
[0003] Although the crusher is fixed by the rigid connection mode, the vibration can be effectively restricted in a short time, but the connection part is easy to loosen in long-term use, which is not reliable. Therefore, at present, when the crusher is installed, the corresponding flexible buffer device is usually arranged between the crusher main body and the supporting base for damping. The most commonly used flexible damping device at present is spring, but the problem of the spring is that the reduction of the amplitude of the crusher equipment is determined by the size of the vibration impact of the crusher equipment, when the vibration impact of the equipment increases, the deformation of the spring will increase, and obviously the reduction effect of the amplitude is weakened, and the greater the vibration impact of the crusher equipment, the more the amplitude needs to be reduced to protect the internal parts, so the spring as the flexible buffer device has obvious defects. SUMMARY

[0011] The mounting cavity is provided with through holes penetrating through the upper and lower ends of the support base, and the diameter of the through holes is greater than the inner diameter of the buffer ring, so that the buffer ring has enough space to support the deformation when the buffer ring bears the vibration; the through holes are coaxially corresponding with the buffer ring, and since the vibration occurs in multiple directions, the space of the through holes can meet the requirement of the multi-directional deformation of the buffer ring.

[0017] The utility model will be further explained in detail in combination with the drawings and specific embodiments.
[0018] For example, Figures 1-3As shown in the figure, a crusher damping device, including a support base 2 arranged below the crusher body 1; a plurality of mounting cavities 3 are opened on the support base 2; the inside of the mounting cavity 3 is correspondingly sleeved with a buffer ring 4; the buffer ring 4 is one-to-one corresponding with the mounting hole position on the crusher body 1; the upper and lower ends of the mounting cavity 3 are respectively provided with through holes 5 penetrating through the upper and lower ends of the support base 2; the through hole 5 is coaxial with the buffer ring 4, and the diameter of the through hole 5 is greater than the inner diameter of the buffer ring 4; the crusher body 1 is connected with the buffer ring 4 one-to-one through the connecting bolt 6; the buffer ring 4 comprises an external packaging sleeve 7 and a buffer liquid 8 filled in the packaging sleeve 7; the packaging sleeve 7 is made of rubber material; the buffer liquid 8 is made of shear thickening fluid material.
[0019] When the crusher body 1 vibrates, the vibration is transmitted to the buffer ring 4 through the connecting bolt 6, and the external packaging sleeve 7 and the internal buffer liquid 8 of the buffer ring 4 can reduce the vibration by their own elastic deformation, thereby protecting the crusher body 1.
[0020] The buffer liquid 8 adopts shear thickening fluid, which has shear thickening effect. When the shear stress, i.e. the vibration impact force in the present scheme, increases, the resistance to external force increases, which shows that the viscosity increases, that is, the hardness increases, which means that the ability to resist deformation increases, so that in the present scheme, the stronger the vibration impact of the crusher body 1, the stronger the vibration amplitude reduction effect, which meets the protection requirements of the crusher body 1 and effectively adapts to the buffer effect of various degrees of vibration impact.
[0021] As shown in the figure, Figures 1-2 A plurality of partition blocks 9 for supporting the crusher body 1 are fixed on the upper side of the support base 2; the partition block 9 is made of rubber material. The partition block 9 separates the crusher body 1 from the support base 2, so that when the crusher body 1 vibrates, rigid friction does not occur between the crusher body 1 and the support base 2.
[0022] As shown in the figure, Figures 2-3 A steel screw sleeve 10 is fixedly sleeved in the middle of the buffer ring 4; the screw sleeve 10 is correspondingly matched with the connecting bolt 6. The steel screw sleeve 10 can ensure the firm connection between the connecting bolt 6 and the buffer ring 4, and avoid loosening of the connecting bolt 6 and the buffer ring 4.
[0023] As shown in the figure, Figures 1-2 The upper through hole 5 is provided with a slag ring 11; the inner diameter of the slag ring 11 is greater than the diameter of the through hole 5; the slag ring 11 is fixed with the support base 2; the height of the slag ring 11 is consistent with the height of the partition block 9. The setting of the slag ring 11 can block the foreign matters such as slag outside, so as to prevent the foreign matters from entering the upper through hole 5 position and affecting the buffer and damping process.
