Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to an elastic shock absorbing mechanism and a vibrating screen. Background Art

[0002] Vibrating screen is widely used in coal and other industries. It is a screening device used for material classification, washing, dehydration and de-mediuming. Vibrating screen generally includes a supporting structure, an elastic shock absorbing mechanism, a vibrating screen body and an exciter. The exciter is arranged on the vibrating screen body and generates a periodically changing excitation force to make the vibrating screen body vibrate continuously. The elastic shock absorbing mechanism is arranged between the supporting structure and the vibrating screen body to reduce the dynamic load transmitted from the vibrating screen body to the supporting structure.

[0003] The traditional elastic shock-absorbing mechanism has a single shock-absorbing direction. When the working conditions of the vibrating screen change, the working angle of the vibrating screen body needs to be adjusted, and the elastic shock-absorbing mechanism needs to be disassembled and adjusted at the same time to make the shock-absorbing direction of the elastic shock-absorbing mechanism coincide with the load direction of the vibrating screen body. The entire adjustment process is cumbersome and the adjustment operation has great limitations, resulting in a small adjustment range of the working angle of the vibrating screen body, which cannot well balance the screening efficiency and processing volume of the vibrating screen.

[0004] In order to solve the problems existing in the aforementioned traditional elastic shock absorbing mechanism, Chinese patent CN216827104U provides a vibrating screen and an elastic shock absorbing mechanism, the elastic shock absorbing mechanism includes a base, a support, and a plurality of elastic members abutting between the base and the support, and the elastic deformation directions of the elastic members are arranged at an angle to each other. The elastic shock absorbing mechanism provided in the present application has each elastic member abutting between the support and the base at different angles, so that the elastic shock absorbing mechanism has multiple shock absorbing directions to adapt to different working angles of the vibrating screen body, so that when adjusting the working angle of the vibrating screen body, there is no need to disassemble and assemble the elastic shock absorbing mechanism, which can effectively simplify the adjustment operation of the working angle of the vibrating screen, and the adjustment range of the working angle is large, which can well balance the screening efficiency and processing capacity of the vibrating screen.

[0005] The elastic shock-absorbing mechanism in this patent cannot adjust the installation angle to compensate for the installation error between the supporting structure and the vibrating screen body during installation when there is a large error in the installation dimensions between the supporting structure of the vibrating screen and the vibrating screen body, thereby causing the shock-absorbing spring in the elastic shock-absorbing mechanism to be in an abnormally compressed state, and the two ends cannot be completely perpendicular to their respective contact surfaces.

[0032] like Figures 1 to 6 As shown, an embodiment of the present application provides an elastic shock absorbing mechanism, including an elastic support component 11, a first connecting member 12 and a second connecting member 13, wherein the first connecting member 12 is fixedly connected to one end of the elastic support component 11, and one end of the first connecting member 12 is rotatably connected to the second connecting member 13 to adjust the installation angle of the elastic support component 11 relative to the second connecting member 13.

[0033] like Figure 7 and Figure 8 As shown, specifically, in one embodiment, a first slot structure 121 is provided at one end of the first connecting member 12 connected to the second connecting member 13. The first slot structure 121 extends along the axial direction of the first connecting member 12 and penetrates the end and side of the first connecting member 12. Figure 1 and Figure 2 One end of the second connecting member 13 is inserted into the first connecting member 12 from one side of the first connecting member 12 and passes through the first slot structure 121 .

[0034] like Figure 7 and Figure 8 As shown, specifically, in one embodiment, the first connecting member 12 is a square block structure, and the first slotted structure 121 is a cross slotted structure. Specifically, in one embodiment, a chamfered structure 122 is provided at the end of the square block structure, and a transition arc groove structure 123 is provided at the bottom of the cross slotted structure. It is easy to understand that the end of the square block structure can be provided with a rounded corner or a chamfered angle structure, and the first connecting member 12 is provided with a chamfered structure 122 and a transition arc groove structure 123 respectively to reduce stress concentration. The cross slotted structure divides the end of the first connecting member 12 into four parts to produce elastic deformation so that friction is generated between the first connecting member 12 and the second connecting member 13. Under the fastening force of the fastening assembly 14, there is no axial rotation between the first connecting member 12 and the second connecting member 13. Specifically, in one embodiment, a circular through groove 125 is provided on the first connecting member 12, and the small shaft end of the second connecting member 13 is penetrated through the circular through groove 125.

[0035] like Figure 1 , Figure 2 and Fig. 9 As shown, specifically, in one embodiment, a second slotted structure 131 is provided at one end of the second connecting member 13 close to the first connecting member 12, and the second slotted structure 131 extends along the axial direction of the second connecting member 13 and penetrates the outer circumference of the second connecting member 13. Specifically, in one embodiment, the second connecting member 13 is a circular stepped shaft structure, the outer diameter of one end of the second connecting member 13 corresponding to the second slotted structure 131 is smaller than the outer diameter of the other end thereof, and the second slotted structure 131 is a straight slotted structure.

[0036] like Figure 1 and Figure 2 As shown, specifically, in one embodiment, at least two groups of mounting holes 124 are provided on one end of the first connecting member 12 connected to the second connecting member 13, and the mounting holes 124 are respectively used for the fastening assembly 14 to pass through the first slotted structure 121 to fix the second connecting member 13. In one embodiment, the fastening assembly includes bolts, nuts and washers. The first connecting member 12 and the second connecting member 13 are assembled by at least two groups of fastening assemblies 14. If one of the groups is loose, it will not affect the operation of the mechanism, device or equipment provided with the elastic shock absorbing mechanism, such as a vibrating screen, and due to the setting of the first slotted structure 121 and the second slotted structure 131, the first connecting member 12 and the second connecting member 13 will produce elastic deformation during the assembly and clamping process of the fastening assembly 14, and the elastic deformation is generated to adapt to the loosening of the small stroke of the bolt to offset the influence of the loosening of part of the fastener.

[0037] like Figure 1 and Figure 2 As shown, specifically, in one embodiment, the elastic support assembly 11 includes a first support member 111, a second support member 112 and an elastic support member 113; wherein the elastic support member 113 is arranged between the first support member 111 and the second support member 112, the first connecting member 12 is welded and fixed to the top of the second support member 112, and the elastic support member 113 can be a shock absorbing spring, which is perpendicular to the first support member 111 and the second support member 112 at different angles. Fig.10 As shown, in one embodiment, the first support member 111 and the second support member 112 are both bent plate structures, and the two ends of the second support member 112 are respectively provided with an upward or downward bending flange structure 114. By providing the bending flange structure 114, the rigidity of the second support member 112 can be effectively increased. Similarly, the two ends of the first support member 111 can also be provided with a bending flange structure to increase the rigidity. Positioning columns are respectively welded on the first support member 111 and the second support member 112 to position and fix the elastic support member 113 such as a shock absorbing spring, and the elastic support member 113 connects the first support member 111 and the second support member 112.

[0038] The elastic shock absorbing mechanism of the embodiment of the present application welds the first support member 111 in the elastic support assembly 11 to the screen frame of the vibrating screen, and sleeves the first connecting member 12 on the small shaft end of the second connecting member 13. The fastening assembly 14 is not used for fixing first. During the installation process of the screen box and the screen frame of the vibrating screen, elastic supporting members 113 such as shock absorbing springs are used to connect the first supporting member 111 and the second supporting member 112 respectively. Because there may be problems such as installation size error, the elastic supporting members 113 such as shock absorbing springs are not only subjected to axial force. At this time, the installation angle of the entire elastic supporting assembly 11 can be adjusted by adjusting the angle between the first connecting member 12 and the second connecting member 13 to compensate for the installation error between the screen box and the screen frame, so that the two ends of the elastic supporting members 113 such as shock absorbing springs can be completely perpendicular to their respective contact surfaces, so as to reduce or eliminate the force of the elastic supporting members 113 such as shock absorbing springs that intersects with its axial direction, such as lateral force, and change the abnormal pressure state of the elastic supporting members 113 such as shock absorbing springs.

[0039] Based on the same inventive concept as the above embodiments, the present application provides a vibrating screen, including a screen box, a screen frame and the elastic shock absorbing mechanism in the above embodiments, wherein the elastic support assembly is fixedly connected to the screen frame, and the second connecting member is fixedly connected to the screen box. Therefore, the screen box and the screen frame are not rigidly connected, thus avoiding direct impact of the vibrating screen on the screen frame.

[0040] According to the above embodiments, it can be seen that the elastic shock absorbing mechanism and the vibrating screen involved in the utility model, through the rotatable connection structure of the first connecting member and the second connecting member, can realize that the elastic support assembly can adjust the installation angle during the installation process to compensate for the installation error between the two mounting parts respectively fixedly connected to the elastic shock absorbing mechanism, so that the elastic support members in the elastic support assembly can be more completely vertical on their respective contact surfaces, and no force intersecting the axial direction of the elastic support members will be generated due to the installation error, thereby avoiding that the elastic support members in the elastic shock absorbing mechanism are in an abnormally compressed state.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
