Description

Technical Field

[0001] This invention relates to the field of cone crusher technology, and in particular to a vibration reduction structure for a cone crusher. Background Technology

[0002] Cone crushers utilize the eccentric motion of the moving cone to crush and release medium or finely crushed ores between the fixed and moving cone liners, thereby achieving the crushing purpose. Because the drive assembly is located at the bottom, it is mostly supported by a simple frame structure during operation. Such frames often lack vibration damping capabilities. Furthermore, given the core horizontal vibration characteristic of cone crushers, existing vibration damping structures are difficult to fully adapt. Therefore, a vibration damping structure for cone crushers is needed. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a vibration reduction structure for a cone crusher, which has the advantages of high compatibility with cone crushers, good vibration reduction effect, and convenient installation.

[0004] To achieve the above objectives, the technical solution of the present invention is: a vibration damping structure for a cone crusher, which is located below the cone crusher and used to connect the cone crusher to the ground. The vibration damping structure includes supports, a fixed base, and an oscillation assembly. Several supports are located below the fixed base, and the cone crusher passes through the top of the fixed base and is fixedly connected to it. The oscillation assembly includes swing rods, a counterweight housing, and an amplifying rod. Several swing rods are arranged in a ring around the bottom of the cone crusher, with their two ends respectively connected to the bottom of the fixed base and the top of the counterweight housing. The amplifying rod is located inside the counterweight housing, and its sidewall is provided with several extension portions. Several limiting rings are equidistantly arranged inside the counterweight housing. The extension portions and the limiting rings are alternately arranged, and a spring is connected between them. The spring provides an upward preload to the amplifying rod, causing it to abut against the bottom of the cone crusher. During the operation of the cone crusher, the counterweight housing resets under the action of gravity and counteracts the vibration transmitted by the fixed base.

[0005] Furthermore, a magnetic element one is laid on the inner ring of the limiting ring, and a magnetic element two is laid on the side wall of the amplifying rod between adjacent extensions. The magnetic poles of the magnetic element one and the magnetic element two are the same.

[0006] Furthermore, the support is equipped with an electromagnetic generator below the center of the cone crusher, and a magnetic element is laid at the center of the bottom of the counterweight housing. Activating the electromagnetic generator causes the counterweight housing to move towards a vertical state.

[0007] Furthermore, the top of the electromagnetic generator is an upwardly curved arc shape, and the center of the bottom of the counterweight housing is provided with an upwardly curved arc groove.

[0008] Furthermore, the swing rod includes rod one, rod two, a limiting seat, a rotating seat one, and a rotating seat two. Rotating seat one and rotating seat two are rotatably disposed at the bottom of the fixed seat and the top of the counterweight housing, respectively, facing each other. One end of rod one is rotatably connected to rotating seat one, one end of rod two is rotatably connected to rotating seat two, and the other end of rod one is rotatably connected to the other end of rod two. The limiting seat is disposed at the connection between rod one and rotating seat one. Controlling the thickness of the limiting seat allows the swing range of rod one on rotating seat one to be changed.

[0009] Furthermore, the limiting seat includes a U-shaped seat and a fan-shaped airbag. The U-shaped seat is fixedly connected to a rotating seat. The opening of the U-shaped seat faces the rod. The fan-shaped airbag is located inside the U-shaped seat. Inflating the fan-shaped airbag allows for adjustment of the swing angle range of the rod.

[0010] Furthermore, the vibration damping structure also includes a buffer seat with an opening for fixing, a positioning groove at the bottom of the bracket, a limiting post at the top of the buffer seat, the limiting post being movably inserted into the positioning groove, and a spring 2 between the limiting post and the positioning groove.

[0011] Furthermore, the buffer seat is provided with an L-shaped auxiliary component, the bent part of which is rotatably connected to the buffer seat. The side wall of the bracket is provided with a groove, and when the bracket presses down on one side of the L-shaped auxiliary component, the other side of the L-shaped auxiliary component is embedded in the groove.

[0012] Furthermore, the other side of the L-shaped auxiliary component has a semi-cylindrical protrusion, and the bottom of the bracket is frustum-shaped. When the bracket presses down on one side of the L-shaped auxiliary component, the other side of the L-shaped auxiliary component is not parallel to the side wall of the bracket.

[0013] Furthermore, the counterweight housing is covered with a rubber membrane at the top of the amplifying rod.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are:

[0015] This invention connects and fixes the cone crusher with a support and a fixed base, forming a unified transmission system. This facilitates vibration damping between the cone crusher and the ground via an oscillating component on the support. By suspending the oscillating component within the support, the inertia of the nearly cylindrical component, which has a large self-weight, after being offset by external forces, resonates with the vibration received by the support, thus counteracting the vibration generated by the cone crusher from within the support. This enhances the support's vibration damping function. The oscillating component has a simple structure, suitable for various application scenarios. Furthermore, by incorporating an amplifying rod within the oscillating component, which elastically contacts the bottom of the cone crusher, another connection is added between the oscillating component and the cone crusher, increasing their resonance effect. Simultaneously, the elastic connection between the amplifying rod and the counterweight housing further intensifies the reset effect of the oscillating component.

[0016] This invention, by incorporating an electromagnetic generator, not only assists in increasing the resetting force of the oscillation component but also allows for control over the swing range of the oscillation component by altering the magnetic force of the electromagnetic generator during operation, thus achieving controllable vibration reduction. By replacing a flexible rope connection with a swing rod, the angle changes of the swing rod are more synchronized, better suited to the planar vibration of the cone crusher, and improve the resonance effect. Furthermore, the swing range of the swing rod is controlled by a fan-shaped airbag, allowing for appropriate adjustments based on on-site conditions and facilitating operation.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0041] Reference Figure 1-8 The present invention provides a technical solution: a vibration damping structure for a cone crusher 1, which is located below the cone crusher 1 and is used to connect the cone crusher 1 and the ground. The connection method is to fix the cone crusher 1 to the side wall of the cone crusher 1 through a flange, which is the prior art.

[0042] The vibration damping structure includes a support 2, a fixed base 3, and an oscillation assembly 4. Several supports 2 are located below the fixed base 3, and the cone crusher 1 passes through the top of the fixed base 3 and is fixedly connected to it. The oscillation assembly 4 includes a swing rod 41, a counterweight housing 42, and an amplifying rod 43. Several swing rods 41 are arranged in a ring around the bottom of the cone crusher 1, and their two ends are respectively connected to the bottom of the fixed base 3 and the top of the counterweight housing 42. Specifically, the swing rod 41 includes a first rod 411, a second rod 412, a limiting seat 413, a first rotating seat 414, and a second rotating seat 415. Rotary seat 1 414 and rotary seat 2 415 are respectively rotatably mounted at the bottom of fixed seat 3 and the top of counterweight housing 42. One end of rod 1 411 is rotatably connected to rotary seat 1 414, and one end of rod 2 412 is rotatably connected to rotary seat 2 415. The length of rod 1 411 is less than that of rod 2 412. The other end of rod 1 411 is rotatably connected to the other end of rod 2 412. Limiting seat 413 is located at the connection between rod 1 411 and rotary seat 1 414. The thickness of limiting seat 413 is controlled to change the swing range of rod 1 411 on rotary seat 1 414. The thickness of the limiting seat 413 can be changed by having the limiting seat 413 include a U-shaped seat 4131 and a fan-shaped airbag 4132. The U-shaped seat 4131 is fixedly connected to the rotating seat 414, with the opening of the U-shaped seat 4131 facing the rod 411. The fan-shaped airbag 4132 is located inside the U-shaped seat 4131. Inflating the fan-shaped airbag 4132 adjusts the swing angle range of the rod 411. The fan-shaped airbag 4132 is connected to an external independent gas cylinder or air inlet pipe via wiring through the limiting seat 413, depending on the actual use. If the cone crusher 1 is operating stably and no debugging is required, the fan-shaped airbag 4132 can be sealed with a valve and only needs to be inspected periodically. To enhance the transmission between the oscillation assembly 4 and the cone crusher 1, an amplifying rod 43 is positioned within the counterweight housing 42. The amplifying rod 43 has several extensions 431 circumferentially arranged on its sidewall. The counterweight housing 42 has several equidistant limiting rings 421. The extensions 431 and limiting rings 421 are alternately arranged, and a spring 44 connects them. The spring 44 applies an upward preload to the amplifying rod 43, causing it to contact the bottom of the cone crusher 1. The amplifying rod 43 transmits the vibration directly to the cone crusher 1 to the counterweight housing 42 via the spring, improving the sensitivity of the counterweight housing 42 to the vibration of the cone crusher 1. To further increase the sensitivity of the relative positional changes between the amplifying rod 43 and the counterweight housing 42, a magnetic element 1 is laid on the inner ring of the limiting ring 421, and a magnetic element 2 is laid on the sidewall of the amplifying rod 43 between adjacent extensions 431. The magnetic poles of the magnetic element 1 and the magnetic element 2 are the same. During the operation of the cone crusher 1, the counterweight housing 42 resets under the action of gravity and counteracts the vibration transmitted by the fixed base 3, resulting in good vibration reduction. At this time, in order to stabilize the environment inside the housing, a rubber membrane 422 is placed on top of the amplifying rod 43 of the counterweight housing 42.

[0043] To prevent insufficient gravity in the oscillation assembly 4, an auxiliary reset structure is provided. An electromagnetic generator 21 is positioned below the center of the cone crusher 1 on the support 2. A magnetic component 3 is placed at the center of the bottom of the counterweight housing 42. Activating the electromagnetic generator 21 causes the counterweight housing 42 to move towards a vertical position. To improve the alignment between the electromagnetic generator 21 and the magnetic component 3, the top of the electromagnetic generator 21 is an upwardly curved arc, and an upwardly curved arc groove is provided at the center of the bottom of the counterweight housing 42. Magnetic components 1, 2, and 3 are all laid out using magnetic materials through bonding, nesting, or any other method.

[0044] To further increase the buffer between the support 2 and the ground, the vibration damping structure also includes a buffer seat 5. The buffer seat 5 has an opening 51 for fixing to the ground. The bottom of the support 2 has a positioning groove 22, and the top of the buffer seat 5 has a limiting post 52. The limiting post 52 can be movably inserted into the positioning groove 22, and a spring 53 is provided between the limiting post 52 and the positioning groove 22. If necessary, an L-shaped auxiliary component 54 is provided on the buffer seat 5. The bent part of the auxiliary component is rotatably connected to the buffer seat 5. The side wall of the support 2 has a groove 23. When the support 2 presses down on one side of the L-shaped auxiliary component 54, the other side of the L-shaped auxiliary component 54 is inserted into the groove 23. The bottom of the support 2 is frustum-shaped, and the buffer seat 5 has a groove for the L-shaped auxiliary component 54 to be inserted. The other side of the L-shaped auxiliary component 54 has a semi-cylindrical protrusion. When the support 2 presses down on one side of the L-shaped auxiliary component 54, the other side of the L-shaped auxiliary component 54 is not parallel to the side wall of the support 2.

[0045] Working principle: First, fix the buffer seat 5, then insert the bracket 2 into the limiting post 52. At this time, the L-shaped auxiliary part 54 receives a force and swings, with its other end engaging the groove 23 to achieve movable limiting of the bracket 2. When the cone crusher 1 is in use, its vibration drives the oscillating component 4 to swing. Under the action of gravity and magnetic force, the swinging oscillating component 4 has a restoring force. The interaction of these two forces causes its vibration to resonate with the cone crusher 1, canceling out part of its vibration and thus achieving the purpose of vibration reduction. During use, the swing range of the limiting rod 411 can be adjusted by changing the inflation status of the fan-shaped airbag 4132, thereby changing the swing range of the oscillating component 4 and adjusting the intensity of the vibration reduction effect.
