[0002] Mining screening equipment is a specialized material grading machine used in the mining industry. It is primarily used to screen crushed ore, coal, sand, and other granular materials according to different particle sizes. This equipment typically employs structures such as vibrating screens, drum screens, or probability screens. It achieves efficient separation by using vibration or rotation to stratify materials and pass them through screens of different apertures. Mining screening equipment must possess high strength, wear resistance, dustproofing, and impact resistance to adapt to the harsh mining operating environment. Its core components include screen boxes, vibrators, and shock absorbers. It is widely used in mineral processing, coal processing, and building materials, and is a key piece of equipment in the mineral processing flow.

[0003] The automatic vibration frequency adjustment mechanism of mining screening equipment usually uses a vibrator to achieve vibration adjustment. However, due to the harsh working environment in mines, the vibrator is exposed to high dust environment for a long time, which can easily lead to component wear or failure due to dust intrusion, thereby reducing the service life of the equipment.

[0027] Example

[0028] Reference Figure 1-5 This embodiment of the present invention provides an automated vibration frequency adjustment mechanism for a mining screening device, comprising:

[0029] The vibration adjustment mechanism 100 includes a mounting base 110, a vibrator 120 fixedly mounted inside the mounting base 110, and an actuator shaft 130 fixedly mounted at the output end of the vibrator 120.

[0030] The dustproof mechanism 200 includes a dustproof component 210 for preventing dust from the output end of the vibrator 120, and a heat dissipation component 220 for assisting in the heat dissipation of the vibrator 120.

[0031] The dustproof component 210 and the heat dissipation component 220 work together to form a dustproof barrier at the output end of the vibrator 120, effectively blocking external dust from entering. At the same time, they assist the vibrator 120 in heat dissipation, solving the problem of accelerated wear and shortened lifespan of the bearings of the vibrator 120 in mining screening equipment due to dust pollution. This improves the dustproof performance and heat dissipation efficiency of the vibrator 120, thereby extending its service life.

[0032] Specifically, the dustproof component 210 includes a mounting cylinder 211 disposed on the outside of the vibrator 120, and a dust cover 212 fixedly mounted on the top of the mounting cylinder 211.

[0033] The mounting sleeve 211 and the dust cover 212 are used to prevent dust from entering the output end of the vibrator 120, thus avoiding dust affecting the use of the bearing at the output end of the vibrator 120.

[0034] Furthermore, a mounting ring 213 is fixedly mounted on the top of the mounting base 110 by bolts, and a mounting cylinder 211 is fixedly mounted on the top of the mounting ring 213.

[0035] The mounting ring 213 is used to install and fix the mounting cylinder 211, thereby improving the stability of the mounting cylinder 211 in use.

[0036] Preferably, the heat dissipation component 220 includes a mounting plate 221 fixedly mounted on the output end of the vibrator 120, two transmission blocks 222 fixedly mounted on the top of the mounting plate 221, a movable plate 223 elastically mounted on the top of the vibrator 120 and used in conjunction with the transmission blocks 222, and a high-resilience airbag 224 fixedly mounted inside the dust cover 212 and used in conjunction with the movable plate 223.

[0037] Furthermore, the dust cover 212 has several first heat dissipation channels 225 inside that are connected to the high-resilience airbag 224, and the mounting cylinder 211 has several second heat dissipation channels 226 on its surface that are connected to the first heat dissipation channels 225.

[0038] The air squeezed out of the high-resilience airbag 224 is guided by the first heat dissipation channel 225 and the second heat dissipation channel 226, so that the air flows through the inside of the dust cover 212 and the surface of the mounting cylinder 211, thereby improving the heat dissipation effect on the mounting cylinder 211 and the dust cover 212 and avoiding poor heat dissipation of the vibrator 120.

[0039] Furthermore, both the movable plate 223 and the high-resilience airbag 224 have internal connecting grooves for use with the actuator shaft 130, and the inner diameter of the connecting grooves is larger than the diameter of the actuator shaft 130.

[0040] Specifically, two return springs 227 are fixedly mounted on the surface of the vibrator 120, and the other end face of the return spring 227 is fixedly connected to the moving plate 223.

[0041] The reset spring 227 is used to pull the moving plate 223 downward and reset it, so that the moving plate 223 can squeeze the high rebound airbag 224 in the next round.

[0042] Furthermore, one side of the transmission block 222 is inclined to facilitate the pressing and moving of the moving plate 223.

[0043] By tilting one side of the transmission block 222, it is easier for the transmission block 222 to drive the moving plate 223 to move upward when rotating, thereby squeezing the high-resilience airbag 224.

[0044] In use, the surface of the high-resilience airbag 224 is connected to an air inlet pipe, and a one-way valve is fitted onto the surface of the air inlet pipe. When the vibrator 120 is running, the vibrator 120 drives the mounting plate 221 at its output end to rotate. The mounting plate 221 drives two transmission blocks 222 to rotate. When the inclined surface of the transmission block 222 rotates to the surface of the moving plate 223, the inclined surface presses upward against the moving plate 223, causing the moving plate 223 to move upward and press against the high-resilience airbag 224. The high-resilience airbag 224 is compressed, and the air inside it flows into the interior of the first heat dissipation channel 225 and passes through the first heat dissipation channel. The air flows through the second heat dissipation channel 225 and then through the second heat dissipation channel 226 across the surface of the mounting cylinder 211. When the top of the transmission block 222 detaches from the surface of the moving plate 223, the moving plate 223 is pulled back to its original position under the elastic force of the return spring 227. At this time, the high-resilience airbag 224 quickly restores its shape. The air inside the mounting cylinder 211 and the dust cover 212 enters the interior of the high-resilience airbag 224 through the air inlet pipe to achieve air exchange and dissipate heat for the vibrator 120. External air enters the interior of the mounting cylinder 211 through the air inlet with a filter screen. The air inlet is located on the surface of the mounting cylinder 211.

[0045] In summary, the cooperation between the dustproof component 210 and the heat dissipation component 220 forms a dust barrier at the output end of the vibrator 120, effectively blocking external dust from entering. At the same time, it assists the vibrator 120 in heat dissipation, solving the problem of accelerated wear and shortened lifespan of the bearings of the vibrator 120 in mining screening equipment due to dust pollution. This improves the dustproof performance and heat dissipation efficiency of the vibrator 120, thereby extending its service life.
