Description

Technical Field

[0001] The utility model relates to the technical field of crusher auxiliary equipment, in particular to an anti-seismic device for a shale crusher. Background Art

[0002] Shale is a rock formed by dehydration and cementation of clay. It is often processed by crushing and screening to make sand and gravel aggregate with appropriate particle size and reasonable mix so that it can be used in construction and other applications.

[0003] When the existing crushing equipment is performing crushing work, the crusher will cause the entire crusher to shake. Therefore, a shock-absorbing structure is generally added to the crusher. Commonly used shock-absorbing structures are simple springs, dampers and other structures, which are mostly arranged at the bottom of the equipment. However, in actual use, the crusher will also shake to the four sides. The above-mentioned traditional vertical shock-absorbing method has high requirements on the strength of the connection and cannot reduce the amplitude of the crusher shaking to the four sides, which can easily cause the connection of the shock absorber to loosen or deform, thereby causing the position of the crusher to shift. Moreover, this vertically arranged shock-absorbing structure is passive shock-absorbing, with general shock-absorbing effect and poor stability. Utility Model Content

[0004] Based on the above description, the utility model provides a shale crusher anti-seismic device to solve the shortcomings of the existing crusher shock-absorbing equipment, which has poor shock-absorbing effect and is very easy to cause deformation or loosening of the connection due to shaking to the four sides.

[0005] The utility model is realized through the following technical solutions:

[0006] A shale crusher anti-seismic device comprises a base, a shock absorbing platform is arranged on the top of the base, a crusher body is arranged above the shock absorbing platform, and a flange is arranged on the outer wall of the crusher body, a through hole is arranged at the center of the shock absorbing platform, and a step surface is extended outward around the top surface of the through hole, the flange is embedded in the step surface and the top surface is arranged flush with the top surface of the shock absorbing platform, and a shock absorbing component is also arranged on the top surface of the shock absorbing platform, and the shock absorbing component is arranged on the periphery of the crusher body and connected to the side wall of the crusher body.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, an air spring is provided on the step surface, and the air spring is arranged in a ring shape. The upper and lower surfaces of the air spring are fixedly connected to the flange and the step surface by bolts respectively.

[0009] Furthermore, the shock absorbing assembly includes a diagonal member and an articulated seat, wherein the diagonal member is provided in plurality and is arranged obliquely around the periphery of the crusher body, and the articulated seat is provided in two groups and is arranged around the top surface of the shock absorbing platform and the periphery of the crusher body respectively.

[0010] Furthermore, the inclined pull member is composed of a hydraulic cylinder and a return spring, wherein spring disks are provided at both upper and lower ends of the hydraulic cylinder, the return springs are arranged at both ends of the spring disks, and hinged joints are respectively provided on the top and bottom surfaces of the two spring disks, and the hinged joints are movably hinged to the hinged seat.

[0011] Furthermore, an elastic pad is provided on the inner side wall of the through hole, the side wall of the crusher body passes through the cylinder and extends the lower half to the bottom of the shock absorbing platform, and the elastic pad and the side wall of the crusher body are in contact with each other.

[0012] Furthermore, the four corners of the bottom of the base are respectively provided with brackets, and the bottoms of the four brackets are all provided with universal wheels with brakes.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] 1. The present application is improved based on the existing shock-absorbing structure. It not only uses air springs for connection to block the transmission of vibration, but also uses surrounding inclined-stayed members for auxiliary support. This inclined-stayed structure can not only actively apply a pulling force to the box body, but also apply a pulling force in the opposite direction when the upper base shakes around, thereby reducing the amplitude of the shaking. Compared with general shock-absorbing equipment, the present application has an anti-seismic effect and can greatly enhance the stability of the crusher. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0021] Combination Figure 1-3 As shown, a shale crusher anti-seismic device comprises:

[0022] The base 1 is the bottom support of the whole device, and is a rectangular square plate structure with a hollow center. Brackets 11 are respectively provided at the four corners of the bottom surface for auxiliary support;

[0023] The shock absorbing platform 2 is arranged on the top surface of the base 1 and is fixed to the base 1 by bolts. The two are arranged concentrically, and a circular through hole 21 is provided at the center of the shock absorbing platform 2, and stepped surfaces are provided on the four sides of the through hole 21;

[0024] The crusher body 3 is arranged at the center of the top surface of the shock-absorbing platform 2, and is mainly used to further refine and crush the shale fragments through the internal crushing structure to process them to the specified requirements;

[0025] The shock absorbing assembly 4 is arranged on the top surface of the shock absorbing platform 2, and is arranged around the periphery of the crusher body 3, and actively applies a pulling force to the crusher body 3, thereby achieving a certain anti-seismic effect.

[0026] Specifically; in this embodiment, the shock absorbing platform 2 should be configured as a circular pedestal, and an air spring 23 is arranged on the step surface. The air spring 23 is arranged in a ring structure, and its main function is to support and connect the crusher body 3, so as to isolate the transmission of vibration and reduce the impact of vibration on other components. Therefore, the crusher body 3 should be provided with a flange on its outer wall, and the flange can be completely embedded in the interior of the through hole 21, so that its top surface is flush with the top surface of the shock absorbing platform 2, and the edges of the two should also retain a certain distance to prevent collision and damage during the left and right shaking process.

[0027] Based on the above structure, both sides of the air spring 23 should adopt flanges or other connecting structures, and they should be locked and fixed to the top surface of the step surface and the bottom surface of the flange by bolts. Therefore, when the vibration is transmitted to the hollow air spring 23, the vibration will be blocked and cannot be transmitted further, thereby effectively reducing the impact caused by the vibration of the equipment.

[0028] Since the entire crusher body 3 will have a certain offset when shaking, in order to ensure that the through hole 21 does not collide with the outer shell of the crusher body 3, a layer of elastic pad 22 should be simultaneously provided on the inner wall. The elastic pad 22 can be made of rubber or soft material structure such as shock-absorbing sponge to make it fit with the outer wall of the crusher body 3.

[0029] The shock absorbing assembly 4 is composed of an inclined member and an articulated seat 45. One inclined member and two articulated seats 45 are set as a group, and multiple groups are arranged. The connection structure of several groups of inclined members and articulated seats 45 surrounds the periphery of the crusher body 3, and one of the two articulated seats 45 is fixedly installed on the outer wall of the crusher body 3, and the other is arranged on the top surface of the shock absorbing platform 2, so that the inclined member is arranged tilted as a whole. This structure can not only provide auxiliary support for the crusher body 3, but also form a reverse pulling force in the convenient direction during actual use, and form an anti-seismic effect in conjunction with the pulling force actively applied, thereby greatly improving the stability of the crusher body 3.

[0030] In the above structure, the inclined member should adopt a spring damper structure, that is, it is composed of a hydraulic cylinder 41 and a return spring 44. Spring disks 42 are respectively arranged at both ends of the hydraulic cylinder 41, and a hinge joint 43 is arranged on the end surface of the spring disk 42. The return spring 44 is arranged between the two spring disks 42. When squeezed, the structure can reduce the impact of vibration by telescoping the hydraulic cylinder 41 and absorb part of the vibration. At the same time, the structure applies an oblique pulling force by actively oblique pulling, which can effectively ensure the stability of the crusher body 3. In addition, during the shaking process, the shaking force can be offset by a reverse pulling force, which further weakens the vibration amplitude and improves the anti-seismic effect.

[0031] At the same time, in order to facilitate the transportation and use of the crusher body 3, a universal wheel 12 can be installed at the bottom end of the bracket 11 at the bottom of the base 1, and a brake assembly can be provided.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
