[0002] Mobile cone crushers are mechanical equipment used to crush hard materials such as rock and ore. They are characterized by their ability to be moved between different work sites, improving work efficiency and reducing material transportation costs. They are widely used in industries such as construction, mining, and road construction, particularly where on-site processing of stone and ore is required. For example, in quarries, they can be used to break large boulders into smaller particles; on construction sites, they can be used to process construction waste.

[0003] According to the different modes of movement, mobile cone crushers can be divided into two types: tire-type and crawler-type. Tire-type is generally suitable for relatively flat road conditions, while crawler-type is more suitable for working in complex terrain, such as mines or on land.

[0045] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0046] The following combination Figures 1 to 7 , describing the embodiments of the present utility model.

[0047] According to an embodiment of the present invention, on the one hand, a crusher support structure is provided, comprising: a support base 2, an adjustment base 4, and an adjustment mechanism 5; the support base 2 has a first fixing area and a second fixing area, the first fixing area being used to fix the crushing main unit 3 of the crusher; the adjustment base 4 is movably arranged on the support base 2, and the adjustment base 4 has a fixed state fixed to the support base 2 and an adjustment state movable relative to the support base 2, and the adjustment base 4 is used to fix the driving member 6 of the crusher; the adjustment mechanism 5 is connected to the support base 2 and the adjustment base 4, and the adjustment mechanism 5 drives the adjustment base 4 to move to adjust the position of the adjustment base 4 relative to the crushing main unit 3. The driving member 6 is connected to the crushing main unit 3 via a transmission mechanism 11, which is a belt transmission mechanism, and the belt transmission mechanism includes a main pulley, a secondary pulley, and a conveyor belt.

[0048] The crusher support structure of this embodiment comprises a crushing unit 3 and an adjustment base 4 for securing a drive member 6, mounted on a support base 2. The position of the drive member 6 is adjusted via the adjustment base 4. Once the adjustment base 4 is adjusted, the relative position of the drive member 6 and the crushing unit 3 remains constant. During operation, the relative position of the drive member and the crushing unit remains constant, ensuring consistent conveyor belt tension and stable transmission, significantly extending the service life of the drive member 6 and the conveyor belt. Adjusting the position of the adjustment base 4, and thus the position of the drive member 6, and thus the tension of the conveyor belt, is accomplished via an adjustment mechanism 5. This makes adjustment extremely convenient and adaptable to a variety of conveyor belt lengths, providing a wide range of applications and strong adaptability.

[0049] Furthermore, the conveyor belt is a V-shaped belt, the driving member 6 is a driving motor, and the driving motor is connected to the crushing host 3 through a V-shaped belt, a main pulley, and a slave pulley. After the position of the driving motor is adjusted, the relative position with the crushing host 3 remains unchanged. During the operation, the tension of the V-belt does not change, the transmission is stable, and the service life of the driving member 6 and the V-belt is greatly extended.

[0050] Specifically, the crushing host 3 and the support base 2 are rigidly connected, for example, the crushing host 3 and the support base 2 are connected via fasteners.

[0051] In one embodiment, Figure 4 As shown, the adjustment mechanism 5 includes a cooperable rotating member and a movable member. The rotating member is rotatably mounted on the support base 2, and the movable member is connected to the adjustment base 4. Rotating the rotating member drives the movable member and the adjustment base 4 to move. When the position of the driving member 6 needs to be adjusted, the operator rotates the rotating member. The rotation of the rotating member drives the movable member to move, which in turn drives the adjustment base 4 and the driving member 6 thereon to move. The adjustment base 4 is then fixed to the support base 2 to complete the position adjustment of the driving member 6. The adjustment mechanism 5 has a simple structure and is easy to implement.

[0052] In one embodiment, Figure 4 As shown, the rotating part is a lead screw 501, and the moving part is a moving nut. In this case, the adjustment mechanism 5 is a lead screw and nut mechanism. The lead screw 501 is rotatably set on the support base 2, and the moving nut is fixed on the adjustment base 4. The moving nut is threadedly engaged with the lead screw 501. One end of the lead screw 501 forms an operating end. The operator uses a tool to rotate the operating end, thereby driving the moving nut and the adjustment base 4 to move together. There is a tight fit between the lead screw 501 and the moving nut, which can provide high-precision positioning. The lead screw and nut mechanism has high transmission efficiency, a relatively simple structure, is easy to disassemble and maintain, has low cost, is cost-effective, and can withstand large loads. Due to the continuity of the thread, the lead screw and nut mechanism can provide smooth and continuous movement, reducing impact and vibration.

[0053] Furthermore, if Figure 4 As shown, the support seat 2 includes a vertical plate 202, and a connecting hole for the screw 501 to pass through is provided on the vertical plate 202. The screw 501 is provided with locking nuts located on both sides of the vertical plate 202. The setting of the locking nuts makes the screw 501 only rotate on the vertical plate 202 and cannot move. By rotating the head of the adjustment screw 501 in two different directions, clockwise and counterclockwise, the adjustment seat 4 can be moved back and forth on the support seat 2 to complete the loosening and tensioning of the V-belt.

[0054] Specifically, the threads of the lead screw 501 and the moving nut are trapezoidal threads or the like.

[0055] In another embodiment, the rotating member is a gear and the moving member is a rack.

[0056] In one embodiment, Figure 2 As shown, the support base 2 is provided with a shock absorber 7. The shock absorber 7 can reduce vibration transmission, protect the crushing host 3 from excessive stress, ensure that the crushing host 3 moves in the best state, and improve the working efficiency of the crushing host 3.

[0057] Furthermore, the support base 2 is used to be fixed on the frame 1, and the vibration damper 7 is set between the frame 1 and the support base 2. Specifically, a plurality of vibration dampers 7 arranged symmetrically between the support base 2 and the frame 1 are provided, and the horizontal heights of all vibration dampers 7 are consistent, so the vibration reduction effect is better.

[0058] It should be noted that the left, right, front and back directions are Figure 4 The arrows in the middle indicate the directions of "left, right, front, and back".

[0059] In one embodiment, Figure 2 and Figure 3 As shown, the vibration damper 7 includes an upper fixing plate 701, a lower fixing plate 702, and a vibration damper 703 disposed between the upper fixing plate 701 and the lower fixing plate 702. The upper fixing plate 701 is fixed to the support base 2, and the lower fixing plate 702 is fixed to the frame 1. The vibration damper 7 is rigidly connected to the support base 2 and the frame 1 by the two fixing plates, and vibration is damped by the vibration damper 703. The vibration damper 7 has a simple structure and is easy to implement.

[0060] Furthermore, the vibration damper 703 is made of rubber, and in this case the vibration damper 7 can be called a rubber vibration damper.

[0061] It is understandable that, in another embodiment, the shock absorber 7 may also be a hydraulic shock absorber, a spring shock absorber or a composite shock absorber, etc., wherein the composite shock absorber 7 refers to a combination of multiple damping materials, such as a combination of rubber and springs.

[0062] According to an embodiment of the present invention, on the other hand, a mobile crushing device is also provided, including: a frame 1, the above-mentioned crusher support structure and a crusher, the crusher support structure is arranged on the frame 1; the crusher includes a crushing host 3 and a driving member 6, the crushing host 3 is arranged on the support base 2 of the crusher support structure, the driving member 6 is arranged on the adjustment base 4, and the driving member 6 is connected to the crushing host 3 through a transmission mechanism.

[0063] Furthermore, the crushing host 3 includes a movable cone and a fixed cone, etc. In this case, the mobile crushing equipment can be called a mobile cone crushing equipment, and the crushing host 3 can be called a cone crushing host.

[0064] In one embodiment, Figure 5 As shown, the frame 1 is provided with buffers 8 located around the crushing main unit 3. The position of the buffers 8 on the frame 1 is adjustable to adjust the gap between the buffers 8 and the crushing main unit 3. By adjusting the position of the buffers 8, the gap between the buffers 8 and the crushing main unit 3 is adjusted. This can buffer the vibration impact of abnormal vibration caused by overload of the crushing main unit 3 on the entire machine, and also effectively reduce the vibration impact of eccentric vibration of the cone main unit on other components of the entire machine.

[0065] In one embodiment, Figure 5 and Figure 6 As shown, the buffer 8 includes a buffer seat 801 and a buffer body 802. The buffer body 802 is fixed to the buffer seat 801. The buffer seat 801 is provided with a strip-shaped fixing hole, which is fixedly connected to the frame 1 via a fastener. The buffer body 802 can mate with the side surface of the bottom of the crushing main unit 3. By loosening the fastener, the buffer seat 801 can be moved to adjust the position of the buffer 8, and thus adjust the gap between the buffer 8 and the crushing main unit 3. The buffer 8 has a simple structure, is easy to manufacture, and reduces costs.

[0066] Furthermore, the material of the buffer body 802 is polyurethane, etc., and the buffer 8 can be called a polyurethane buffer, etc. The polyurethane buffer has the advantages of high elasticity and wear resistance. Polyurethane buffers are arranged in four directions around the crushing host, which effectively improves the vibration impact of the eccentric vibration of the crushing host on other parts of the whole machine and improves the service life of the equipment.

[0067] In one embodiment, Figure 5 and Figure 7 As shown, the support base 2 has a discharge port corresponding to the discharge port of the crushing main unit 3. The frame 1 is provided with a guide hopper 9 corresponding to the discharge port. The discharge position of the guide hopper 9 is provided with a hook-shaped bent plate 10. The guide hopper 9 is arranged below the crushing main unit 3. When the material is discharged, it can accumulate on the bent plate 10, thereby reducing the wear of the guide hopper 9 and extending the service life of the guide hopper 9.

[0068] In one embodiment, a connecting plate is provided around the material drop opening, and the connecting plate is connected to the guide hopper 9 by a sealing member. The provision of the connecting plate facilitates the connection of the sealing member and reduces the difficulty of assembly. Furthermore, the sealing member is a sealing rubber or the like.

[0069] In one embodiment, Figure 4 As shown, the support base 2 is provided with a strip hole 201 extending in the direction of movement of the adjustment base 4. The strip hole 201 is fixedly connected to the adjustment base 4 via a fastener. The fastener is located in the strip hole 201. The fastener and the strip hole 201 cooperate to guide the movement of the adjustment base 4. After the position of the adjustment base 4 is adjusted, the fastener secures the adjustment base 4 to the support base 2, thereby ensuring that the relative position of the drive motor and the crushing unit 3 remains unchanged.

[0070] Furthermore, the extending direction of the strip-shaped hole 201 is the front-to-back direction. The strip-shaped hole 201 is used to install the adjustment seat 4, and the adjustment seat 4 is used to install and fix the driving motor.

[0071] In related technologies, the movement of the cone crusher main unit is the eccentric movement of the moving cone, and there is inevitable self-vibration. How to reduce the vibration of the cone crusher main unit transmitted to other positions of the whole machine is a key issue that needs to be addressed; there is a change in the center distance between the cone crusher main unit itself and the drive motor, and additional structures are needed to compensate for the change in transmission force. Usually, an auxiliary tensioning wheel or a universal connecting shaft structure is used between the drive motor and the cone crusher main unit to compensate for the position change between the drive motor and the cone main crusher. The structure is relatively complex and the cost is relatively high.

[0072] In this embodiment, an integrated support base 2 is arranged between the cone crusher main unit and the frame 1. The cone crusher main unit and the support base 2 are rigidly connected. An adjustment base 4 for fixing the drive motor is provided on the support base 2, so that the drive motor and the cone crusher main unit are both arranged on the support base 2. There is no relative movement between the cone crusher main unit and the drive motor. The center energy between the main pulley and the slave pulley remains unchanged at all times. The drive of the V-belt will not generate additional force due to frequent changes in the center distance. A vibration absorber 7 is provided at the bottom of the integrated support base 2 and buffers 8 are arranged around it, which effectively reduces the impact of the vibration of the cone crusher main unit on other components of the whole machine, improves the service life of the equipment, and effectively solves the problems of negative vibration and unstable power transmission caused by the vibration of the cone crusher main unit.
