Description
Technical Field
[0001] This utility model relates to the field of crusher technology, specifically a tailings crusher. Background Technology
[0002] Tailings are a byproduct of mineral processing and separation, representing the portion with the lowest content of useful target components. Tailings are not entirely useless waste; they often contain components that can be used for other purposes and can be comprehensively utilized. Tailings hold business opportunities for secondary utilization. Developing and utilizing the large amounts of tailings accumulated over time can not only "turn waste into treasure" but also effectively alleviate resource and environmental pressures. Crushing tailings is a crucial part of the tailings treatment process, typically using a vertical shaft impact crusher.
[0003] For example, Chinese patent CN220634577U discloses a vertical shaft impact crusher with self-protection function, which relates to the technical field of vertical shaft impact crushers. It includes a workbench body, an anti-slip pad installed at the bottom of the workbench body, a mounting frame fixed at the top of the workbench body, a drive motor installed at the top of the mounting frame, a motor drive shaft installed at the top of the drive motor, and a first transmission rod provided at the top of the motor drive shaft. This utility model, by setting a fixed base, support plate, mounting plate, and shock-absorbing column, makes the sand making tank more stable during sand making operations. The addition of shock-absorbing column at the bottom reduces vibration during operation, thus extending the service life of the device. The sand making shaft, driven by a drive motor, transmission belt, sand making tank, feed inlet, rotor, wear-resistant alloy hammers, and impact plate, propels the material onto the impact plate, where it collides violently with the plate and crushes itself. However, in practical use, the integrated design of the rotor and alloy hammers makes it difficult to replace worn alloy hammers after repeated crushing operations. Since the hammers directly impact and crush tailings, they are subject to long-term friction and impact from the ore, gradually wearing down, such as becoming blunt at the edges, developing notches, or thinning. If not replaced in time, they will be unable to crush hard materials, resulting in coarser output particles and decreased crushing efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a tailings crusher to solve the problems mentioned in the background art.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] A tailings crusher includes a support, a drive assembly, and a crushing assembly. The drive assembly and the crushing assembly are respectively disposed on the top sides of the support. The support supports the drive assembly and the crushing assembly. The crushing assembly crushes tailings. The crushing assembly includes a crushing tank with a tank cover at its upper end. A transmission rod is rotatably connected to the bottom end of the tank cover. One end of the transmission rod extends through the tank cover to the outside. A plurality of rotors are connected to the outer wall of the transmission rod. A plurality of vertical grooves are formed on the outer wall of the rotors, and a horizontal groove is formed on one side of the vertical groove. A movable block is slidably disposed inside the horizontal groove. An alloy hammer is installed on one side of the outer wall of the movable block. A second screw hole is formed on both sides of the alloy hammer inside the movable block. A second threaded hole is formed near the second screw hole inside the horizontal groove. A second bolt is threadedly connected between adjacent second screw holes and second threaded holes.
[0007] Furthermore, several rotors are arranged sequentially from top to bottom, the cross-section of the moving block is in the shape of an "I", the outer wall of the moving block slides into the inner wall of the horizontal groove, and the length of the moving block matches the width of the vertical groove.
[0008] The beneficial effects of adopting the above-mentioned further scheme are that there are three rotors. When the transmission rod rotates, the rotors installed on the outside of it rotate with the transmission rod. Under the action of the hammers, the tailings can come into contact with the rotors and the alloy hammers on the outside multiple times during the falling process, thereby improving the crushing efficiency and crushing effect, so that the tailings can be crushed more fully and evenly. At the same time, due to the sliding fit between the inner wall of the outer wall of the moving block and the inner wall of the transverse groove, and the matching of the length of the moving block with the width of the vertical groove, when it is necessary to replace the worn alloy hammers, first loosen and remove the second bolt, and then slide the moving block to one side, so that the moving block moves towards the vertical groove inside the transverse groove. When one side of the moving block is in contact with one side of the inner wall of the vertical groove, slide the moving block downward, so that the two sides of the moving block are in contact with the two sides of the inner wall of the vertical groove. During the continuous downward movement, the moving block is removed from the vertical groove, thereby removing the alloy hammers from the rotor and replacing the worn alloy hammers. At the same time, the cross-section of the moving block is I-shaped, so that the moving block can only move radially along the transverse groove.
[0009] Furthermore, the inner wall of the crushing tank is provided with several sliding grooves, and each of the sliding grooves is slidably connected with a sliding strip. The cross-section of the sliding strip is "I" shaped, and the outer wall of the sliding strip is slidably engaged with the inner wall of the sliding groove. One side of the sliding strip is provided with a counter-attack plate.
[0010] The beneficial effect of adopting the above-mentioned further solution is that, through the setting of the chute and the slide bar, the impact plate and the crushing tank are slidably set. When the impact plate is worn after multiple crushing operations, the tank cover can be opened directly and the impact plate is pulled upward to make the slide bar move along the axial direction of the chute, so that the chute and the slide bar are separated, and the worn impact plate can be replaced. At the same time, the cross-section of the slide bar is I-shaped, so that the slide bar can only move along the axial direction of the transverse groove. The setting of the impact plate can make the tailings bounce and collide and crush again after being hit by the alloy hammer, forming a secondary crushing effect, further improving the degree of crushing, making the tailings particle size smaller, and meeting different application requirements.
[0011] Furthermore, the slide bar has a pair of third screw holes inside, and the counterattack plate has a third threaded hole near the third screw holes inside. A third bolt is threaded between adjacent third screw holes and third threaded holes, and there are no gaps between the counterattack plates at the end away from the slide bar.
[0012] The beneficial effect of adopting the above-mentioned further solution is that the setting of the third bolt allows for quick disassembly and assembly between the slide bar and the impact plate, facilitating the replacement of worn impact plates. Since there are no gaps between the several impact plates at the end away from the slide bar, a continuous and closed crushing chamber is formed inside the crushing tank, preventing tailings from leaking out of the gaps in the impact plates during the crushing process, ensuring the normal operation of the crushing process, and also preventing tailings particles from getting stuck in the gaps.
[0013] Furthermore, the bottom end of the can lid fits into the top end of the crushing can, and the inside of the can lid is provided with a plurality of first screw holes. The inside of the crushing can is provided with first threaded holes near the first screw holes, and a first bolt is threadedly connected between adjacent first screw holes and first threaded holes.
[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting the first bolt, it is easy to quickly disassemble and assemble the tank cover and the crushing tank. When it is necessary to maintain the internal components of the crushing tank, the first bolt can be loosened and removed to quickly open the tank cover, which is convenient for operators to carry out internal operations and improves the maintainability of the equipment.
[0015] Furthermore, one end of the first bolt, the second bolt, and the third bolt is provided with an internal hexagonal groove.
[0016] The beneficial effect of adopting the above-mentioned further solution is that by opening an internal hexagonal groove at one end of the first bolt, the second bolt, and the third bolt, the user can tighten or loosen the first bolt, the second bolt, or the third bolt simply by inserting one end of an internal hexagonal wrench into the internal hexagonal groove at one end of the first bolt, the second bolt, or the third bolt and rotating it.
[0017] Furthermore, the bottom of the crushing tank is provided with a discharge port, the upper end of the tank cover is provided with a feeding hopper, the bottom end of the feeding hopper is provided with two first material inlets, and the tank cover is provided with a second material inlet near the two first material inlets. The feeding hopper is connected to the tank cover, and a cavity is formed between the outer wall of the feeding hopper and the top surface of the tank cover.
[0018] The beneficial effects of adopting the above-mentioned further scheme are that the discharge port at the bottom of the crushing tank facilitates the smooth discharge of the crushed tailings, enabling the crushing operation to be carried out continuously and improving work efficiency. The setting of the feed hopper, the first feed port and the second feed port can evenly guide the tailings into the crushing tank, avoid the tailings from concentrating in one place, ensure that the crushing process in the crushing tank is uniform and stable, and improve the crushing quality.
[0019] Furthermore, the support includes a support frame, with support legs installed at the four corners of the bottom end of the support frame. One side of the top surface of the support frame is fixedly connected to the bottom end of the crushing tank, and one side of the top surface of the support frame is hollow.
[0020] The beneficial effect of adopting the above-mentioned further solution is that the support legs installed at the four corners of the bottom of the support frame increase the contact area between the equipment and the ground, so that the crushed tailings fall to the ground through the discharge port.
[0021] Furthermore, the drive assembly includes a mounting frame, the bottom end of which is fixedly connected to the top surface of the support frame away from the crushing tank. A servo motor is mounted on one side of the mounting frame, and a first drive wheel is driven to the output end of the servo motor. A second drive wheel is provided on one side of the first drive wheel, and a drive belt is wound between the first drive wheel and the second drive wheel.
[0022] Furthermore, the second transmission wheel is disposed inside the cavity, and the second transmission rod is mounted at the end of the transmission rod away from the rotor.
[0023] The beneficial effect of adopting the above-mentioned further solution is that the servo motor can achieve smooth power transmission through the transmission method of the first transmission wheel, the second transmission wheel and the transmission belt. Moreover, the transmission ratio can be adjusted according to actual needs to change the speed of the crushing component to adapt to different crushing conditions and tailings characteristics. When the servo motor is working, the first transmission wheel rotates and accurately transmits the power of the servo motor to the transmission rod through the transmission belt, ensuring the accuracy and stability of the transmission, enabling the rotor to rotate stably, ensuring the normal operation of the crushing operation, and improving crushing efficiency and crushing quality.
[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: In this tailings crusher, due to the sliding fit between the inner wall of the transverse groove of the moving block and the length of the moving block matching the width of the vertical groove, when it is necessary to replace the worn alloy hammerhead, first loosen and remove the second bolt, and then slide the moving block to one side, so that the moving block moves towards the vertical groove inside the transverse groove. When one side of the moving block is in contact with one side of the inner wall of the vertical groove, slide the moving block downward, so that the two sides of the moving block are in contact with the two sides of the inner wall of the vertical groove. During the continuous downward movement, the moving block is removed from the vertical groove, thereby removing the alloy hammerhead from the rotor and replacing the worn alloy hammerhead. At the same time, the cross-section of the moving block is I-shaped, so that the moving block can only move radially along the transverse groove. Through the setting of the sliding groove and the sliding strip, the impact plate and the crushing tank are slidably set. When the impact plate is worn after multiple crushing operations, the tank cover is opened directly and the impact plate is pulled upward, so that the sliding strip moves axially along the sliding groove, so that the sliding groove and the sliding strip are separated, and the worn impact plate is replaced.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-5 This utility model provides a technical solution: a tailings crusher, including a support 1, a drive assembly 2, and a crushing assembly 4. The drive assembly 2 and the crushing assembly 4 are respectively disposed on the top two sides of the support 1. The support 1 is used to support the drive assembly 2 and the crushing assembly 4. The crushing assembly 4 is used to crush tailings. The crushing assembly 4 includes a crushing tank 41. The upper end of the crushing tank 41 is provided with a tank cover 42. The bottom end of the tank cover 42 is rotatably connected to a transmission rod 44. One end of the transmission rod 44 extends through the tank cover 42 to the outside. A plurality of rotors 45 are connected to the outer wall of the transmission rod 44. A plurality of vertical grooves 46 are opened on the outer wall of the rotors 45, and a horizontal groove 47 is opened on one side of the vertical grooves 46. A moving block 48 is slidably disposed inside the horizontal groove 47. An alloy hammer head 49 is installed on one side of the outer wall of the moving block 48. The moving block 48 has openings on both sides of the alloy hammer head 49. A second screw hole is provided, and a second threaded hole is provided inside the transverse groove 47 near the second screw hole. A second bolt 410 is threadedly connected between the adjacent second screw hole and the second threaded hole. Since the outer wall of the moving block 48 slides into the inner wall of the transverse groove 47, and the length of the moving block 48 matches the width of the vertical groove 46, when it is necessary to replace the worn alloy hammer head 49, first loosen and remove the second bolt 410, and then slide the moving block 48 to one side, so that the moving block 48 moves towards the vertical groove 46 inside the transverse groove 47. When one side of the moving block 48 is in contact with one side of the inner wall of the vertical groove 46, slide the moving block 48 downward, so that the two sides of the moving block 48 are in contact with the two sides of the inner wall of the vertical groove 46. During the continuous downward movement, the moving block 48 is removed from the vertical groove 46, thereby removing the alloy hammer head 49 from the rotor 45 and replacing the worn alloy hammer head 49.
[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Please see Figures 1-5This utility model provides a technical solution: a plurality of rotors 45 are arranged sequentially from top to bottom; the cross-section of the moving block 48 is "I"-shaped; the outer wall of the moving block 48 slides in cooperation with the inner wall of the transverse groove 47; the length of the moving block 48 matches the width of the vertical groove 46; a plurality of sliding grooves 411 are provided on the inner wall of the crushing tank 41; a sliding strip 412 is slidably connected inside each of the sliding grooves 411; the cross-section of the sliding strip 412 is "I"-shaped; and the outer wall of the sliding strip 412 slides in cooperation with the inner wall of the sliding groove 411; a counter-attack plate 413 is provided on one side of the sliding strip 412; a pair of third screw holes are provided inside the sliding strip 412; and a third threaded hole is provided inside the counter-attack plate 413 near the third screw holes. A third bolt 414 is threaded between adjacent third screw holes and third threaded holes. Several impact plates 413 are seamless at the ends away from the slide bar 412. The bottom end of the canister lid 42 fits against the upper end of the crushing canister 41. Several first screw holes are provided inside the canister lid 42. First threaded holes are provided inside the crushing canister 41 near the first screw holes. A first bolt 43 is threaded between adjacent first screw holes and first threaded holes. One end of the first bolt 43, second bolt 410, and third bolt 414 is provided with an internal hexagonal groove. Through the arrangement of the slide groove 411 and slide bar 412, the impact plates 413 and the crushing canister 41 are slidably positioned. When the impact plates 413 undergo multiple... After wear occurs during crushing, the tank cover 42 is opened directly, and the impact plate 413 is pulled upwards, causing the slide bar 412 to move axially along the slide groove 411, separating the slide groove 411 from the slide bar 412. The worn impact plate 413 can then be replaced. Simultaneously, the slide bar 412 has an I-shaped cross-section, allowing it to move only axially along the transverse groove 47. The third bolt 414 allows for quick disassembly and assembly of the slide bar 412 and the impact plate 413, facilitating the replacement of the worn impact plate 413. When the transmission rod 44 rotates, the externally mounted rotor 45 rotates along with it. Under the action of the hammer, the tailings repeatedly impact the rotor 45 during its descent. The impact plate 413 contacts the alloy hammer 49 on the outside, thereby improving the crushing efficiency and crushing effect, so that the tailings can be crushed more fully and evenly. The impact plate 413 can rebound and collide with the tailings again after they are hit by the alloy hammer 49, forming a secondary crushing effect, further improving the degree of crushing, making the tailings smaller in size, and meeting different usage requirements. Since there is no gap between the several impact plates 413 at the end away from the slide bar 412, a continuous and closed crushing chamber is formed inside the crushing tank 41, preventing the tailings from leaking out from the gaps in the impact plates 413 during the crushing process, ensuring the normal progress of the crushing process, and also preventing tailings particles from getting stuck in the gaps.
[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Please see Figures 1-5 This utility model provides a technical solution: a discharge port is provided at the bottom of the crushing tank 41, and a feeding bin 3 is installed at the upper end of the tank cover 42. Two first feeding ports are provided at the bottom of the feeding bin 3. A second feeding port is provided on the tank cover 42 near each of the two first feeding ports. The feeding bin 3 is connected to the tank cover 42, and a cavity is formed between the outer wall of the feeding bin 3 and the top surface of the tank cover 42. The support member 1 includes a support frame, with support legs installed at the four corners of the bottom end of the support frame. One side of the top surface of the support frame is fixedly connected to the bottom end of the crushing tank 41, and one side of the top surface of the support frame is hollow. The drive assembly 2 includes a mounting frame 21, the bottom end of which is fixedly connected to the top surface of the support frame away from the crushing tank 41. A servo motor 22 is installed on one side of the mounting frame 21. The servo motor 22 outputs... The output end is connected to a first transmission wheel 23, and a second transmission wheel 24 is provided on one side of the first transmission wheel 23. A transmission belt 25 is wound between the first transmission wheel 23 and the second transmission wheel 24. The second transmission wheel 24 is located inside the cavity, and the second transmission rod 44 is installed at the end of the transmission rod 44 away from the rotor 45. The discharge port at the bottom of the crushing tank 41 facilitates the smooth discharge of the crushed tailings. The setting of the feed bin 3, the first feed port and the second feed port can evenly guide the tailings into the crushing tank 41. When the servo motor 22 is working, the first transmission wheel 23 rotates and transmits the power of the servo motor 22 to the transmission rod 44 accurately through the transmission belt 25, ensuring the accuracy and stability of the transmission, so that the rotor 45 can rotate stably and ensure the normal operation of the crushing operation.
[0037] Specifically, the working principle of this tailings crusher is as follows: During operation, tailings are evenly fed into the crushing tank 41 through the feed hopper 3. When the servo motor 22 is working, the first transmission wheel 23 rotates and transmits the power of the servo motor 22 accurately to the transmission rod 44 through the transmission belt 25. The rotor 45 mounted externally rotates with the rotation of the transmission rod 44, and under the action of the hammers, the tailings can contact the rotor 45 and its external alloy hammers 49 multiple times during the falling process, thereby improving the crushing efficiency and crushing effect, so that the tailings can be crushed more thoroughly and evenly. The impact plate 413 is designed to allow the tailings to rebound and be crushed again after being struck by the alloy hammer 49, creating a secondary crushing effect and further increasing the degree of crushing, resulting in smaller tailings particles. The crushed tailings are then discharged smoothly through the discharge port at the bottom of the crushing tank 41. After multiple crushing operations, the user inserts one end of an Allen wrench into the Allen socket of the first bolt 43, rotates it to loosen and remove the first bolt 43, separating the tank cover 42 from the crushing tank 41. The alloy hammer 49 and the impact plate 413 on the rotor 45 are then inspected. When a certain alloy hammer... When wear occurs on the hammer 49 and the counter-attack plate 413, the user inserts one end of an Allen wrench into the Allen socket of the second bolt 410 and rotates it to loosen and remove the second bolt 410. Then, the user slides the moving block 48 to one side, causing the moving block 48 to move from the horizontal groove 47 towards the vertical groove 46. When one side of the moving block 48 is in contact with one side of the inner wall of the vertical groove 46, the user slides the moving block 48 downward, causing both sides of the moving block 48 to be in contact with the inner walls of the vertical groove 46. During the downward movement, the moving block 48 is removed from the vertical groove 46, thereby removing the alloy hammer head 49 from the rotor. Remove from 45 and replace the worn alloy hammer 49. When the impact plate 413 is worn after multiple crushing operations, directly open the tank cover 42 and pull the impact plate 413 upward to make the slide bar 412 move axially along the slide groove 411, so that the slide groove 411 and the slide bar 412 are separated, and the worn impact plate 413 is replaced. The setting of the third bolt 414 makes it possible to quickly disassemble and assemble the slide bar 412 and the impact plate 413, so as to facilitate the replacement of the worn impact plate 413 and avoid replacing the intact slide bar 412 that has not been in contact with tailings.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
