Description

Technical Field

[0001] The present invention relates to the technical field of mining machinery, and in particular to a mining stone rolling device. Background Art

[0002] During mining operations, it is often necessary to crush large rocks into smaller pieces for subsequent processing and transportation.

[0003] In order to cope with the crushing of stones, the traditional method is to use mining stone crushing equipment to crush the stones. The mining stone crushing equipment uses high-speed rotating hammers to impact, shear and tear the materials to crush them. Under the action of the material's own gravity, the material is rushed from the high-speed rotating hammers to the screen plate in the frame. The screen plate discharges the material smaller than the screen hole size, and the material larger than the screen hole size remains on the screen plate and continues to be hit and ground by the hammer, completing the crushing of the stones.

[0004] However, when the existing mining crushing device encounters sharp-edged ores, such as quartz stone, the hammer head wears faster, and the hammer head needs to be replaced more frequently, which takes a long time to complete the inspection and replacement.

[0005] In addition, most existing mining crushing devices use connecting components to set the hammer head on the rotor to facilitate disassembly and replacement. When replacing, the entire rotor needs to be removed from the device, and then the hammer head needs to be removed from the rotor and replaced. After the replacement is completed, it needs to be reassembled to the device. Although the entire equipment does not need to be completely disassembled, due to the heavy weight of the rotor and hammer head, the entire disassembly process may still be cumbersome, complicated, time-consuming and labor-intensive.

[0006] At the same time, the device needs to be completely stopped during the disassembly process, and the stones cannot be crushed during the entire process. The remaining stones in the device also need to be cleaned to facilitate subsequent reassembly, which reduces the working efficiency of the mine stone crushing device. Summary of the Invention

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention and are not to be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0024] The following describes a mining rock crushing device according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0025] like Figures 1-10 As shown, the mining rock crushing device of an embodiment of the present invention includes a shell 1, a rotor 2, multiple hammer heads 3, a strip support 4, a transfer mechanism 5, multiple guide synchronization mechanisms 6, multiple reinforcement and sealing mechanisms 7 and an extension cylinder 8.

[0026] A crushing chamber is provided in the shell 1 , a screen plate 11 is provided at the bottom of the crushing chamber, an opening is provided at one end of the shell 1 , a main driver 12 is provided at the other end of the shell 1 , and a feed port is provided at the top of the shell 1 .

[0027] It should be noted that the main driver 12 can be an electric motor, which is connected to the rotor 2 to provide high-speed rotational force for the rotor 2, and further drives the hammer head 3 on the rotor 2 to rotate at high speed to achieve the function of crushing mine rocks.

[0028] It is understandable that the crushing chamber can accommodate and install various crushing components, and the screen plate 11 is used to withstand the impact of stones and the hammer head 3, ensuring that the stones are crushed while screening out the crushed stones smaller than the screen holes.

[0029] The rotor 2 is rotatably disposed in the crushing chamber. The interior of the rotor 2 is a hollow structure. A plurality of evenly distributed mounting openings 21 are provided on the rotor 2 . The rotor 2 is connected to the main driver 12 .

[0030] It should be noted that the interior of the rotor 2 is a hollow structure and the overall cylindrical structure is convenient for installing and assembling the relevant components used for the hammer head 3 inside. The multiple installation ports 21 provided on the rotor 2 can be used to install and accommodate the hammer head 3.

[0031] The plurality of hammer heads 3 are respectively disposed in the plurality of mounting openings 21 , and sealing plate slots 32 are provided on both sides of the hammer heads 3 .

[0032] It should be noted that the sealing plate slot 32 on the hammer head 3 is used in conjunction with the sealing plate 71. After the hammer head 3 is installed in the installation opening 21, the sealing plate 71 is engaged in the sealing plate slot 32 to fix the hammer head 3 on the rotor 2, thereby ensuring the reliability of the hammer head 3.

[0033] The strip support 4 is rotatably disposed in the rotor 2 , and one end of the strip support 4 passes through the opening and extends to the outside of the housing 1 .

[0034] It should be noted that the strip support 4 is used to install the transfer mechanism 5, and can pass through the opening of the shell 1 and extend to the outside. Expanding the strip support 4 can facilitate the removal of the replaced hammer head 3 from the outside and the delivery of the hammer head 3 to be replaced into the device.

[0035] The transfer mechanism 5 is arranged on the strip support 4 , and the transfer mechanism 5 includes a transfer seat 51 , a pushing structure 52 and two sets of movable guide structures 53 .

[0036] Among them, the transfer seat 51 is set on the strip support 4, a groove is opened on the transfer seat 51, the hammer head 3 is located in the groove, the pushing structure 52 is set on the strip support 4 and located at the bottom of the transfer seat 51, and two sets of movable guide structures 53 are respectively set at both ends of the transfer seat 51.

[0037] It should be noted that the pushing structure 52 pushes the transfer seat 51. The groove on the transfer seat 51 can accommodate the replaced hammer head 3 and the hammer head 3 to be replaced. The transfer seat 51 is pushed to make it close to the edge of the rotor 2 for installation and removal of the hammer head 3.

[0038] The movable guide structure 53 plays a guiding role, preventing the transfer seat 51 from shifting during the pushing process and failing to align with the installation opening 21, thereby affecting the replacement of the hammer head 3, and providing stability for the transfer mechanism 5.

[0039] An electromagnet can be set in the transfer seat 51, and an iron plate can be set on the contact surface between the corresponding hammer head 3 and the transfer seat 51. The electromagnet can firmly adsorb and fix the hammer head 3 to prevent the hammer head 3 from being thrown out due to the centrifugal force generated by the rotation of the rotor 2.

[0040] The movable guide structure 53 also plays a movable driving function, driving the transfer seat 51 to move on the strip support 4.

[0041] The plurality of guide synchronization mechanisms 6 are all provided on the rotor 2 and are respectively located on the plurality of mounting openings 21 . The guide synchronization mechanisms 6 include a guide synchronization frame 61 , a movable synchronization plate 62 and a movable structure 63 .

[0042] Among them, the guide synchronization frame 61 is set on the rotor 2 and is respectively located on the installation opening 21. A notch is opened at one end of the guide synchronization frame 61, the movable synchronization plate 62 is set at the end of the guide synchronization frame 61 away from the notch, and the movable structure 63 is set at the other end of the guide synchronization frame 61.

[0043] It is understandable that the guide synchronization frame 61 is opposite to the installation opening 21 , and plays a role in further guiding the hammer head 3 , ensuring that the hammer head 3 can enter the installation opening 21 .

[0044] A notch is set on one side of the guide synchronization frame 61. Since the device does not stop when replacing and installing the hammer head 3, the rotor 2 continues to rotate. Only by allowing the transfer mechanism 5 and the rotor 2 to rotate synchronously can the relative stillness of the two be achieved and the hammer head 3 can be installed. One end of the notch allows the hammer head 3 to pass through, and the end without the notch will push the hammer head 3 to drive the transfer mechanism 5 to follow the rotation, so as to achieve synchronous motion control of the two.

[0045] It should be noted that the movable synchronization plate 62 is movably set on the guide synchronization frame 61, and a driving component can be set to drive it. It moves relative to the guide synchronization frame 61 and extends to the outside of the guide synchronization frame 61 to push the transfer seat 51 to run synchronously with it.

[0046] It can be understood that the movable structure 63 can drive the guide synchronization frame 61 to move. After approaching the hammer head 3, it pushes the transfer mechanism 5 through the end without a notch to follow the synchronous rotation. The transfer mechanism 5 continues to push the hammer head 3, and the hammer head 3 enters the guide synchronization frame 61 and plays a guiding role, ensuring that the hammer head 3 can smoothly enter the installation port 21.

[0047] The plurality of reinforcement and blocking mechanisms 7 are all provided on the rotor 2 and are respectively located on the plurality of mounting openings 21 . The reinforcement and blocking mechanisms 7 include two blocking plates 71 and a driving structure 72 .

[0048] The two blocking plates 71 are respectively arranged on both sides of the installation opening 21 , and the driving structure 72 is arranged on the rotor 2 and located at one end of the installation opening 21 . The driving structure 72 is respectively connected to the two blocking plates 71 .

[0049] It should be noted that the two sealing plates 71 can be assembled in the installation opening 21 to directly seal the installation opening 21. After the damaged hammer head 3 is replaced, the installation opening 21 can be temporarily sealed by the sealing plate 71 to prevent stones being crushed outside from entering the rotor 2.

[0050] It can be understood that after the damaged hammer head 3 is removed, the driving structure 72 controls the sealing plate 71 to seal the installation port 21. When the new hammer head 3 is installed, the hammer head 3 can be fixed by cooperating with the sealing plate slot 32, which plays an auxiliary role in the replacement and installation of the hammer head 3.

[0051] The extension tube 8 is provided at one end of the shell 1 and is communicated with the opening, and one end of the strip support 4 is located in the extension tube 8 .

[0052] It can be understood that the internal space of the extension tube 8 can accommodate the strip support 4 and play a certain supporting role for the strip support 4.

[0053] Wherein, both ends of the installation opening 21 are provided with strip grooves 22 , and both ends of the hammer head 3 are provided with strip blocks 31 , and the strip blocks 31 are located in the strip grooves 22 .

[0054] It can be understood that during the installation process, the hammer head 3 can fall into the installation port 21 with the help of the gravity of the hammer head 3 itself and the guiding effect of the guide synchronization frame 61. Since the sealing plate slot 32 has not been fixed in time when entering the installation port 21, the bar 31 cooperates with the strip groove 22 to limit the hammer head 3, preventing the hammer head 3 from directly falling out of the rotor 2, and also limiting the position of the sealing plate slot 32, which facilitates the fixation of the sealing plate 71.

[0055] A cover plate 81 is provided at one end of the extension tube 8 , and the cover plate 81 is pivotally connected to the extension tube 8 .

[0056] A vertical plate 41 is provided on the inner bottom surface of the extension tube 8 , and the vertical plate 41 is rotatably connected to the strip support 4 . A limiting rod 42 is provided on the vertical plate 41 , and the limiting rod 42 passes through the strip support 4 , the vertical plate 41 and the cover plate 81 .

[0057] It should be noted that the limit rod 42 is movably passed through the strip support 4, the vertical plate 41 and the cover plate 81. The limit rod 42 passes through the strip support 4 and the vertical plate 41, restricting the strip support 4 from rotating, thereby ensuring that the hammer head 3 to be installed inserted from the outside can stably enter the rotor 2 for installation. Pulling out the limit rod 42 can release the restriction, and the strip support 4 is controlled by the guide synchronization frame 61 and the transfer mechanism 5 to rotate synchronously, so as to ensure that the transfer seat 51 and the guide synchronization frame 61 can be relatively still to complete the installation of the hammer head 3.

[0058] The vertical plate 41 and the strip support 4 can be rotatably connected via a rotating shaft, and the limiting rod 42 passes through the cover plate 81, so that the limiting rod 42 can be directly controlled from the outside.

[0059] It can be understood that the vertical plate 41 can support the strip support 4, solving the problem that the strip support 4 has poor support when it is only connected to the rotor 2. The cover plate 81 is provided to seal the extension tube 8 to prevent external dust from entering the rotor 2, thereby increasing the service life of the rotor 2 and reducing interference.

[0060] Specifically, when the hammer head 3 is disassembled and replaced, the relevant staff operates the pushing structure 52 to drive the transfer seat 51 to lift, and at the same time drives the movable synchronization plate 62 to move on the guide synchronization frame 61 until the movable synchronization plate 62 rotates with the rotor 2 and contacts the edge of the transfer seat 51 to push the transfer seat 51 to move synchronously. At this time, the transfer seat 51 corresponds to the guide synchronization frame 61 synchronously.

[0061] The relevant staff reduces the speed of the main drive 12, and the speed of the rotor 2 is reduced accordingly. The operating drive structure 72 controls the sealing plate 71 to move to both sides, releasing the fixation of the sealing plate slot 32 of the damaged hammer head 3. When the rotor 2 drives the hammer head 3 to rotate to the top, the hammer head 3 is affected by its own gravity and is separated from the centrifugal force control of the rotor 2. The hammer head 3 breaks away from the mounting port 21 and falls onto the transfer seat 51, and the operating electromagnet adsorbs the hammer head 3.

[0062] The relevant staff operates the pushing structure 52 to contract, driving the transfer seat 51 and the hammer head 3 to move toward the strip support 4. After contracting a certain distance, the strip support 4 and the transfer seat 51 slowly stop rotating without being driven by the movable synchronization plate 62. At this time, the relevant staff opens the cover plate 81, inserts the limit rod 42 to stabilize the strip support 4, and drives the transfer seat 51 to the opening of the extension tube 8 through the movable guide structure 53. The relevant staff removes the damaged hammer head 3 from the transfer seat 51 and places the new hammer head 3 into the transfer seat 51 for adsorption and fixation.

[0063] Close the cover 81, the movable guide structure 53 drives the transfer seat 51 back to the inside of the rotor 2, and the relevant staff re-operates the pushing structure 52 to lift the transfer seat 51. The transfer seat 51 drives the hammer head 3 to lift, pulls out the limit rod 42, and releases the restriction on the strip support 4. The relevant staff operates the movable structure 63 to drive the guide synchronization frame 61 to move, so that the controlled guide synchronization frame 61 contacts the hammer head 3, the notch engages the hammer head 3, and pushes the hammer head 3 to rotate synchronously with the rotor 2.

[0064] The hammer head 3 has completely entered the guide synchronization frame 61, and a part of it has entered the installation port 21. The relevant staff operates the driving structure 72 to control the sealing plate 71 to open the installation port 21, and releases the adsorption and fixation of the hammer head 3 by the transfer seat 51. When the rotor 2 drives the hammer head 3 to rotate downward, the hammer head 3 falls under the influence of its own gravity and completely enters the installation port 21. It is limited by the strip groove 22 and the bar block 31. At the same time, the driving structure 72 is started to control the sealing plate 71 to enter the sealing plate slot 32 for engagement and fixation, completing the reinstallation of the hammer head 3.

[0065] After completing the above steps, repeat the operation to replace the other hammer heads 3 in sequence. After all the replacements are completed, the rotation speed of the main driver 12 is restored and the mine rock crushing device continues to operate.

[0066] In one embodiment of the present invention, Figure 7 and Figure 9 As shown, the pushing structure 52 includes a top plate 521 , two movable rods 522 , two movable blocks 523 , two driving blocks 524 , a first bidirectional screw rod 525 and a first driver 526 .

[0067] Among them, the top plate 521 is set on the strip support 4 and is located at the bottom of the transfer seat 51. The two movable rods 522 are both set below the top plate 521. The two movable rods 522 are cross-distributed and rotatably connected. The two movable blocks 523 are respectively rotatably set at the top ends of the two movable rods 522. Two parallel movable tracks are opened on the top plate 521, and the two movable blocks 523 are respectively located in the two movable tracks.

[0068] Among them, the two driving blocks 524 are respectively arranged at the bottom ends of the two movable rods 522, the first bidirectional screw rod 525 is arranged below the movable rod 522, the two ends of the first bidirectional screw rod 525 are respectively threadedly connected to the two driving blocks 524, and the first driver 526 is arranged on the strip support 4 and connected to one end of the first bidirectional screw rod 525.

[0069] It should be noted that the first driver 526 can be a servo motor, which can directly drive the first bidirectional screw 525 to rotate by remote control. The threads at both ends of the first bidirectional screw 525 are in opposite directions, thereby being able to control the two drive blocks 524 connected thereto to move in opposite directions.

[0070] It can be understood that the two movable rods 522 are rotatably connected to each other, and the movable rods 522 can rotate with each other to change the height, and the top plate 521 can be pushed and controlled. The setting of the movable block 523 and the movable track can ensure that the top plate 521 will not be separated from the movable rods 522. The first bidirectional screw rod 525 and the first driver 526 at the bottom realize the rotational drive of the two movable rods 522, and realize the pushing control of the top plate 521.

[0071] Specifically, when the relevant staff wants to push the transfer seat 51, they drive the first bidirectional screw 525 to rotate by running the first driver 526, and then drive the two driving blocks 524 to move in opposite directions. The two movable rods 522 rotate to lift the top plate 521, and the top plate 521 pushes the transfer seat 51.

[0072] In one embodiment of the present invention, Figure 4 and Figure 6 As shown, the movable guide structure 53 includes a telescopic rod 531 , a connecting plate 532 , a fixing frame 533 and an electric guide wheel 534 .

[0073] Among them, the telescopic rod 531 is arranged at one end of the transfer seat 51, the connecting plate 532 is arranged at the top of the telescopic rod 531, one end of the connecting plate 532 is connected to the transfer seat 51, the fixing frame 533 is arranged on the telescopic rod 531, the electric guide wheel 534 is arranged at one end of the fixing frame 533, a guide rail is opened on the strip support 4, and the electric guide wheel 534 is located in the guide rail.

[0074] It should be noted that the electric guide wheel 534 can be a roller controlled by a motor, which can be driven to move within the guide rail. When the electric guide wheel 534 is running, it can drive the fixed frame 533 and telescopic rod 531 components connected to it to follow the movement, ensuring that the transfer seat 51 can move on the strip support 4.

[0075] It can be understood that the telescopic rod 531 itself can be extended, and is connected to the strip support 4 through the fixing frame 533, and is connected to the transfer seat 51 through the connecting plate 532, which can ensure that the transfer seat 51 is always guided by the telescopic rod 531 during the lifting process, will not separate from the strip support 4, and provides stability.

[0076] Specifically, when the relevant staff needs to transport the hammer head 3 out or send it into the rotor 2, they run the electric guide wheel 534 to drive the hammer head 3 on the transfer seat 51 to move on the strip support 4 to complete the transportation of the hammer head 3. When the hammer head 3 is disassembled and installed, the transfer seat 51 is lifted, and the telescopic rod 531 restricts the transfer seat 51 to provide stability for the transfer seat 51 and avoid shaking and deviation.

[0077] In one embodiment of the present invention, Figure 8 and Figure 10As shown, the movable structure 63 includes a second driver 631 and a transverse plate 632 .

[0078] The second driver 631 is provided at the other end of the guide synchronization frame 61 , one end of which is connected to the rotor 2 ; the transverse plate 632 is provided at the other end of the second driver 631 , one end of which is connected to the guide synchronization frame 61 .

[0079] It should be noted that the second driver 631 can be an electric push rod, which can be connected to the cross plate 632 through fasteners. The fasteners can be a combination of screws, bolts, nuts and connecting plates. The cross plate 632 can be connected to the guide synchronization frame 61 through fasteners, and the second driver 631 can be connected to the rotor 2 through fasteners.

[0080] It can be understood that the second driver 631 pushes the cross plate 632, that is, controls the guide synchronization frame 61 to move on the rotor 2. Since multiple hammer heads 3 are provided, multiple corresponding guide synchronization frames 61 are also provided, allowing the guide synchronization frame 61 to move, ensuring that only the controlled guide synchronization frame 61 can contact the hammer head 3, and guide and synchronously drive the hammer head 3, avoiding obstruction caused by other guide synchronization frames 61.

[0081] In order to clearly illustrate the above embodiment, in one embodiment of the present application, Figure 8 As shown, a third driver 621 is provided on the movable synchronization plate 62 , and the third driver 621 is connected to the guide synchronization frame 61 .

[0082] It should be noted that the third driver 621 can be an electric push rod, which can be connected to the guide synchronization frame 61 through fasteners. The third driver 621 can push the movable synchronization plate 62, allowing the movable synchronization plate 62 to extend out to resist the transfer seat 51, and push the transfer seat 51 to follow the synchronous rotation.

[0083] Since the volume of the transfer seat 51 corresponds to the volume of the guide synchronization frame 61, the guide synchronization frame 61 cannot resist and push the transfer seat 51, so an additional component is required. The movable synchronization plate 62 is a component that extends out to resist and push the transfer seat 51.

[0084] Specifically, when installing the hammer head 3, the relevant staff can run the second driver 631 to control the guide synchronization frame 61 to clamp the hammer head 3, drive the hammer head 3, the transfer seat 51 and the strip support 4 to rotate synchronously with the rotor 2, so as to ensure that the transfer seat 51 and the guide synchronization frame 61 are relatively stationary, and ensure the installation of the hammer head 3. When disassembling the hammer head 3, the transfer seat 51 needs to be synchronized with the guide synchronization frame 61 when the hammer head 3 has not entered the transfer seat 51. The relevant staff runs the movable synchronization plate 62, uses the movable synchronization plate 62 to resist the transfer seat 51, and controls the transfer seat 51 to rotate synchronously and remain relatively stationary with the guide synchronization frame 61.

[0085] In one embodiment of the present invention, Figure 3 、 Figure 5 and Figure 8 As shown, the driving structure 72 includes two driving plates 721 , a second bidirectional screw rod 722 and a fourth driver 723 .

[0086] Among them, the two driving plates 721 are respectively connected to the two sealing plates 71, the second bidirectional screw rod 722 is rotatably set on the rotor 2, the two ends of the second bidirectional screw rod 722 are respectively threadedly connected to the two driving plates 721, and the fourth driver 723 is set at one end of the second bidirectional screw rod 722 and connected to it.

[0087] It should be noted that the second bidirectional screw rod 722 is a screw rod with opposite threads at both ends, and the fourth driver 723 is an electric motor. The fourth driver 723 is connected to the second bidirectional screw rod 722 to control its rotation.

[0088] It can be understood that the second bidirectional screw 722 is threadedly connected to the two drive plates 721, and the two drive plates 721 are respectively connected to the two sealing plates 71. Through the drive of the fourth driver 723, the two sealing plates 71 are controlled to move in opposite directions, so that the sealing plates 71 can be used to realize the opening and closing control of the installation port 21.

[0089] Specifically, when the relevant staff needs to seal or open the installation port 21 and fix the hammer head 3, they control the fourth driver 723 to drive the second bidirectional screw 722 to rotate, and the second bidirectional screw 722 controls the drive plate 721 to drive the two sealing plates 71 to move in opposite directions.

[0090] In summary, the mining rock crushing device of the embodiment of the present invention can replace the hammer head without disassembling the rotor or stopping the operation of the device. The replacement process saves time and effort, and ensures the efficiency of the device in crushing rocks.
