Technical Field

[0001] The utility model relates to the technical field of vibration screen shock absorption, in particular to a vibration screen shock absorption device. Background Art

[0002] Vibrating screen is a device that uses screening technology to screen materials. Screening technology is widely used in coal, metallurgy, petroleum, chemical industry, building materials, environmental protection and other fields. It is a key link in the production process of most enterprises. Therefore, vibrating screen is widely used. During the use of vibrating screen, its shock absorber is one of the main components.

[0003] However, the following problems still exist in actual use:

[0004] Most existing shock-absorbing devices only have one set of shock-absorbing components. During long-term practical use, the fatigue level of the shock-absorbing components gradually increases, which causes the shock-absorbing components to be unable to provide the required shock-absorbing force, thereby affecting the normal use of the vibrating screen. At the same time, when damage occurs, it will also force the device to be unable to work effectively. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a shock-absorbing device for a vibrating screen, which has the advantages of being able to reduce the fatigue of the shock-absorbing components and extend the service life of the shock-absorbing device by using two groups of shock-absorbing components in combination. At the same time, when one group is damaged, the other group can also ensure the normal operation of the device, thereby solving the problems raised in the background technology.

[0006] The camshaft is connected to the support frame by a spring, and the camshaft is connected to the support frame by a spring. The camshaft is connected to the support frame by a spring. The camshaft is connected to the support frame by a spring.

[0007] Preferably, the multiple groups of shock absorbing mechanisms include an end seat 1, a receiving seat, an end seat 2, a support arm 1 and a support arm 2.

Four groups of cylindrical rubber strips 1 are arranged inside the end seat 1 and the end seat 2, and four groups of cylindrical rubber strips 2 are arranged on both sides of the receiving seat.

[0008] Preferably, the connecting seat 2 and the connecting seat 1 are both connected to the base 1 and the base 2 through bolts, and the connecting seat 3 and the connecting seat 4 are both connected to the bearing plate 1 and the bearing plate 2 through bolts.

[0009] Preferably, two groups of spring assemblies are provided between the first load-bearing plate and the second load-bearing plate, and the two groups of spring assemblies are symmetrically arranged about the center line of the first load-bearing plate and the second load-bearing plate.

[0010] Preferably, a connecting seat 3 and a connecting seat 4 are respectively provided at both ends of the back of the supporting plate 1 and the supporting plate 2, and the connecting seat 3 and the connecting seat 4 are symmetrically arranged with respect to the center line of the supporting plate 2 and the supporting plate 1.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The vibration damping device of the vibrating screen is provided with a shock-absorbing mechanism 1 and a shock-absorbing mechanism 2.

The structural feature of the shock-absorbing mechanism 2 is X-shaped, while the structural feature of the shock-absorbing mechanism 1 is V-shaped. Through the cooperation of the spring assembly in the shock-absorbing mechanism 2 and the cylindrical rubber strip 1 and the cylindrical rubber strip 2 in the shock-absorbing mechanism 1, the vibration force exerted on the base 1 and the base 2 is effectively buffered, thereby achieving effective vibration reduction while ensuring the normal operation of the vibrating screen. The setting of this structure can effectively perform vibration reduction operations and avoid the impact contact between the base 1 and the base 2, which causes the device to fail to operate normally. At the same time, the combination of the shock-absorbing mechanism 1 and the shock-absorbing mechanism 2 avoids the situation of insufficient shock absorption caused by the existing use of one set of shock-absorbing components. At the same time, if one set is damaged, the other set of shock-absorbing components can still ensure the normal operation of the device without hindering normal operation, thereby improving the practicality of the device.
