[0002] In the field of gold mining, ore crushing is a crucial process. With the continuous increase in gold demand and the increasing scale of mining, higher requirements are placed on the efficiency and quality of ore crushing.

[0003] Traditional ore crushing devices often use a relatively simple crushing structure when processing gold ore. Generally, only a combination of a movable jaw plate and a fixed jaw plate is used for simple extrusion crushing. This method is difficult to adapt to the complex hardness characteristics and irregular shapes of gold ore. Many ores have texture structures inside, and a single fixed extrusion mode cannot effectively crush along the texture, resulting in incomplete crushing. Multiple reworks are required later, which greatly reduces mining efficiency. Moreover, after long-term use, the jaw plate is severely worn. Due to its integrated design, it is difficult and costly to replace, which seriously affects production continuity. Summary of the invention

[0004] The invention provides a crushing device for ore processing, which solves the problem that the jaw crusher in the related art has poor crushing effect and the crushing tooth plate is inconvenient to replace.

[0005] The technical solution of the present invention is as follows: A crushing device for ore processing, comprising a frame, a movable jaw guard, a movable jaw plate and a fixed jaw plate, wherein the movable jaw plate and the fixed jaw plate are arranged opposite to each other, and the movable jaw plate comprises: A mounting plate, eccentrically rotatably disposed on the frame, the mounting plate having a mounting groove; A fixed tooth plate is detachably arranged in the installation groove, and a plurality of sliding grooves are arranged at intervals in the horizontal direction on the fixed tooth plate; There are a plurality of movable tooth plates, each of which is slidably disposed in one of the slide grooves; There are several top blocks, which are spaced apart on the movable jaw guard plate, and the end of the movable tooth plate slides against the surface of the top block; after the mounting plate moves, the movable tooth plate reciprocates along the slide groove under the guidance of the top block surface.

[0006] Optionally, the movable tooth plate is always in contact with the top block, and the top block is located on the moving path of the movable tooth plate.

[0007] Optionally, the top blocks contacting the two ends of the same movable tooth plate are centrally symmetrical.

[0008] Optionally, the fixed tooth plate has a plurality of tooth grooves, each of which has a through hole, and further comprises: There are a plurality of hammer rods, each of which is telescopically arranged in one of the through holes, and the hammer rod passes through the mounting plate; A top plate is arranged on the frame, one end of the hammer rod is in contact with the top plate, and after the mounting plate moves, the hammer rod is lifted up by the top plate.

[0009] Optionally, the mounting plate has a through slot, the diameter of the through slot is larger than the diameter of the hammer rod, and the through hole has a flared opening, further comprising: A first limiting plate, arranged on the hammer rod; A spring is arranged in the through slot, one end of the spring abuts against the first limiting plate, and the other end of the spring abuts against the flared portion, and the spring is used to provide a force for resetting the hammer rod.

[0010] Optionally, the top plate has an arc-shaped protrusion, and the hammer rod abuts against the arc-shaped protrusion.

[0011] Optionally, the hammer rod has a hammer head, and the hammer head is conical, and further comprises: A baffle is arranged in the tooth groove, the hammer rod passes through the baffle, the hammer head is located outside the baffle, and the baffle is used to limit the hammer rod for protection.

[0015] The working principle and beneficial effects of the present invention are: In the present invention, after starting the equipment, the mounting plate rotates eccentrically, and as the mounting plate moves, the fixed tooth plate moves synchronously. Under the guidance of the top block, the movable tooth plate slides back and forth along the slide groove. During the reciprocating sliding of the movable tooth plate, the teeth on the movable tooth plate are laterally misaligned with the teeth on the fixed tooth plate, thereby enhancing the crushing function. When the movable jaw plate approaches the fixed jaw plate, the ore between the two is squeezed. Since the movable tooth plate can slide flexibly, the crushing force can better act along the ore texture, thereby achieving more efficient crushing.

[0020] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1 to Figure 11, which is an embodiment of the present invention, provides a crushing device for ore processing, including a frame 1, a movable jaw guard plate 2, a movable jaw plate 3 and a fixed jaw plate 4, the movable jaw plate 3 and the fixed jaw plate 4 are arranged relatively, the movable jaw plate 3 includes a mounting plate 31, the mounting plate 31 is eccentrically rotatably arranged on the frame 1, and the mounting plate 31 has a mounting groove 312; the fixed tooth plate 32 is detachably arranged in the mounting groove 312, and a plurality of slide grooves 322 are horizontally arranged on the fixed tooth plate 32; there are a plurality of movable tooth plates 33, and each movable tooth plate 33 is slidably arranged in a slide groove 322; there are a plurality of top blocks 7, and a plurality of top blocks 7 are spaced apart on the inner wall of the movable jaw guard plate 2, and the end of the movable tooth plate 33 slides and abuts against the surface of the top block 7; after the mounting plate 31 moves, the movable tooth plate 33 reciprocates along the slide groove 322 under the guidance of the surface of the top block 7.

[0023] In the above scheme, the frame 1 is a rectangular parallelepiped structure as a whole, and a shock-absorbing foot pad is provided at the bottom. The top blocks 7 on the inner wall of the movable jaw guard plate 2 are evenly spaced, and the top blocks 7 can be welded or directly cast as one piece with the movable jaw guard plate 2. Each top block 7 corresponds to a movable tooth plate 33. The fixed tooth plate 32 is clamped with the mounting plate 31 through a dovetail groove and fixed by bolts, which is convenient for disassembly and replacement. The inner wall of the slide groove 322 of the fixed tooth plate 32 is polished smooth to reduce the friction force when the movable tooth plate 33 slides. The end of the movable tooth plate 33 is a rounded transition, and the contact mode with the top block 7 is surface contact, which reduces friction loss. The fixed jaw plate 4 is fixed at the front end of the frame 1, opposite to the movable jaw plate 3. The surface of the fixed jaw plate 4 has arranged tooth-shaped protrusions. The tooth shape is arranged according to the crushing requirements of the gold ore, which can effectively crush the ore.

[0024] Working process: After starting the equipment, the mounting plate 31 rotates eccentrically. As the mounting plate 31 moves, the fixed tooth plate 32 moves synchronously, and the movable tooth plate 33 slides back and forth along the slide groove 322 under the guidance of the top block 7. During the reciprocating sliding of the movable tooth plate 33, the teeth on the movable tooth plate 33 are laterally misaligned with the teeth on the fixed tooth plate 32, thereby enhancing the crushing function. When the movable jaw plate 3 is close to the fixed jaw plate 4, the ore between the two is squeezed. Since the movable tooth plate 33 can slide flexibly, the crushing force can better act along the ore texture, thereby achieving more efficient crushing. Compared with the traditional fixed extrusion mode, the movable tooth plate 33 can be dynamically adjusted according to the characteristics of the ore, and can effectively crush gold ores of different hardness and textures, thereby reducing the number of rework times and improving mining efficiency.

[0025] Furthermore, the movable tooth plate 33 is always in contact with the top block 7 , and the top block 7 is located on the moving path of the movable tooth plate 33 .

[0026] In the above scheme, the top block 7 is in the shape of a disk, and the area of ​​the top block 7 is the same as or slightly larger than the area of ​​the eccentric wheel 6. When the mounting plate 31 drives the movable tooth plate 33 to move, the arc surface at the end of the movable tooth plate 33 slides smoothly on the smooth surface of the disk-shaped top block 7. Since the height of the top block 7 gradually changes, the movable tooth plate 33 is periodically pushed laterally while moving, and because the top blocks 7 on the two opposite movable jaw guards 2 on the frame 1 are arranged in opposite directions, the movable tooth plate 33 can achieve reciprocating linear motion when moving, and then cooperate with the fixed tooth plate 32 to stably crush the ore. The disk-shaped top block 7 provides a stable guide for the movable tooth plate 33 to prevent it from deflecting or jamming, ensuring continuous and efficient crushing action and improving the uniformity of ore crushing.

[0027] Furthermore, the top blocks 7 contacted by the two ends of the same movable tooth plate 33 are centrally symmetrical.

[0028] In the above scheme, the top blocks 7 contacted at both ends of the same movable tooth plate 33 are not only arranged in opposite directions, but also, in the entire crushing cycle, as the mounting plate 31 reciprocates, the movable tooth plate 33 is guided by the top blocks 7 at both ends. When the movable jaw plate 3 is driven by the eccentric wheel 6 to move, the movable tooth plate 33 moves back and forth under the guidance of the top blocks 7. It should be noted that during the entire reciprocating transverse movement of the movable tooth plate 33, the two ends of the movable tooth plate 33 are always in contact with the two top blocks 7 arranged oppositely, which can not only improve the moving stability of the movable tooth plate 33, but also improve the transverse crushing ability. It is understandable that pulleys can be installed at both ends of the movable tooth plate 33 to convert the original sliding friction into rolling friction, thereby reducing friction and improving the crushing effect.

[0029] Furthermore, the fixed tooth plate 32 has a plurality of tooth grooves 323, the tooth grooves 323 have through holes 3231, and also includes hammer rods 8, which have a plurality of hammer rods 8, each of which is telescopically arranged in a through hole 3231, and the hammer rods 8 pass through the mounting plate 31; the top plate 10 is arranged on the frame 1, and one end of the hammer rod 8 abuts against the top plate 10. After the mounting plate 31 moves, the hammer rod 8 is lifted up by the top plate 10.

[0030] In the above scheme, the tooth groove 323 of the fixed tooth plate 32 is trapezoidal and has a moderate depth, which is convenient for guiding during the ore crushing process. The through hole 3231 is circular, which reduces the friction resistance of the hammer rod 8 when it is extended and retracted. The head of one end of the hammer rod 8 is thickened to form a hammer head 81, and the other end extends a certain length after passing through the fixed tooth plate 32 and the mounting plate 31, which is convenient for installing the reset spring 12. When the mounting plate 31 moves in the direction away from the fixed jaw plate 4, one end of the hammer head 81 approaches the top plate 10. As the mounting plate 31 continues to move, the top plate 10 blocks the hammer rod 8 from moving, forcing the hammer rod 8 to extend in the through hole 3231, and the ore in the tooth groove 323 is hammered and crushed, forming a composite crushing effect with extrusion crushing, and further refining the ore particles.

[0031] Hammer crushing and extrusion crushing are carried out simultaneously, acting on the ore in multiple dimensions. For the hard parts that are difficult to crush by extrusion, hammering can effectively crush them, making the ore crushing more uniform and thorough. Without increasing the extra process time, composite crushing significantly improves the effect and meets the growing quality requirements of gold mining. Furthermore, the mounting plate 31 has a through slot 313, the diameter of the through slot 313 is larger than the diameter of the hammer rod 8, and the through hole 3231 has a flared opening 3130, which is used to provide a swinging space for the hammer rod 8, and also includes a first limit plate 13, which is arranged on the hammer rod 8; the spring 12 is arranged in the through slot 313, one end of the spring 12 abuts against the first limit plate 13, and the other end of the spring 12 abuts against the flared opening 3130, and the spring 12 is used to provide a force for resetting the hammer rod 8.

[0032] In the above scheme, the through slot 313 of the mounting plate 31 is in the shape of an oblong, the length of which satisfies the telescopic and swinging range of the hammer rod 8 at a certain angle, the width of which is larger than the diameter of the hammer rod 8, and the edges of the through slot 313 are chamfered to prevent scratching the hammer rod 8. The flared opening 3130 in the through hole 3231 is in the shape of a trumpet, and a rubber buffer layer is attached to the inner wall, which can provide space for the swing of the hammer rod 8 and buffer its collision with the hole wall. The first limit plate 13 is a circular steel plate, which is installed at one end of the hammer rod 8 close to the mounting plate 31, and the outer diameter is slightly smaller than the width of the through slot 313.

[0033] After the hammer rod 8 is lifted up by the top plate 10 and hammered, as the mounting plate 31 moves, the spring 12 releases energy, pushes the first limit plate 13 to drive the hammer rod 8 to quickly return to the initial position, ready for the next hammering. The spring 12 cooperates with the through slot 313 and the flared opening 3130 to ensure that the hammer rod 8 does not get stuck or deflect during high-frequency hammering and reset, thereby improving the reliability of the crushing device and reducing downtime.

[0034] Furthermore, the top plate 10 has an arc-shaped protrusion 1001 , and the hammer rod 8 abuts against the arc-shaped protrusion 1001 .

[0035] In the above scheme, the arc-shaped protrusion 1001 of the top plate 10 is hemispherical, the surface of the arc-shaped protrusion 1001 is polished, and a hard alloy sheet is installed at the contact part with the hammer rod 8 to improve wear resistance. It should be noted that the top plate 10 is fixedly mounted on the frame 1, so the top plate 10 is immovable. When the mounting plate 31 moves, the mounting plate 31 follows the eccentric wheel 6 to make an eccentric circular motion, and the mounting plate 31 will drive the hammer rod 8 to make an eccentric circular motion. When the end of the hammer rod 8 is pressed against the top plate 10, due to the guiding and pushing effect of the arc-shaped protrusion 1001, the hammer rod 8 can be quickly extended to hammer the ore. The arc-shaped protrusion 1001 can make the hammer rod 8 extend further outward from the tooth groove 323 to improve the hammering effect, and can also guide the hammer rod 8 to move smoothly along the surface of the arc-shaped protrusion 1001 to improve the smoothness of the device operation.

[0036] Furthermore, the hammer rod 8 has a hammer head 81, which is conical, and also includes a baffle 9, which is arranged in the tooth groove 323. The hammer rod 8 passes through the baffle 9, and the hammer head 81 is located outside the baffle 9. The baffle 9 is used to limit the hammer rod 8.

[0037] In the above scheme, the cone bottom diameter of the hammer head 81 of the hammer rod 8 is larger than the diameter of the hammer rod 8, the ratio of the cone height to the bottom diameter is moderate, the hammer head 81 has high hardness, and the hammer head 81 is fixed to the hammer rod 8 by threaded connection or welding.

[0038] The baffle 9 is a circular rubber plate or steel plate with a circular hole in the middle. The diameter of the circular hole is slightly larger than the diameter of the hammer rod 8, which can effectively limit the protection of the hammer rod 8 and has a certain elasticity to buffer the rebound force of the ore.

[0039] When the hammer rod 8 is lifted up by the top plate 10 to hammer the ore, the conical hammer head 81 can more easily cut into the ore with its sharp head, and the crushing effect is significantly improved. At the same time, the baffle 9 restricts the swing range of the hammer rod 8 to prevent it from shaking excessively. When the ore rebounds, the baffle 9 absorbs part of the energy to protect the hammer rod 8 from damage, ensuring that the hammer rod 8 works stably.

[0040] Furthermore, a slot 311 is provided at the bottom of the mounting plate 31 , and a block 321 is provided at the bottom of the fixed tooth plate 32 . The block 321 is engaged with the slot 311 .

[0041] In the above scheme, the width of the slot 311 is closely matched with the block 321 to ensure stable connection and easy disassembly. The contact surface of the slot 311 and the block 321 has slightly convex textures to increase friction and prevent the fixed tooth plate 32 from loosening during operation. The end of the block 321 is chamfered for easy insertion into the slot 311. When installing the fixed tooth plate 32, the fixed tooth plate 32 is slowly inserted along the slot 311 from the side, and the block 321 slides smoothly into the slot 311 until the fixed tooth plate 32 is fully in place, fits tightly with the mounting plate 31, and is fixed by bolts. When replacement is required, the fixed tooth plate 32 can be removed by gently prying it with a special tool, which is convenient and efficient to operate. The dovetail groove connection does not require complex tools, shortens maintenance time, improves production efficiency, and adapts to the high-intensity operation rhythm of gold mining.

[0042] Furthermore, it also includes a driver 5 , which is arranged on the frame 1 ; an eccentric wheel 6 is arranged on the power output end of the driver 5 , and a mounting plate 31 is arranged on the eccentric wheel 6 .

[0043] In the above scheme, the driver 5 is a variable frequency speed regulating motor, the power is selected according to the ore crushing scale and hardness requirements, the motor housing has cooling fins, a built-in temperature sensor, and is connected to an external controller to achieve intelligent temperature control. The motor is installed on one side of the frame 1 through a shock-absorbing pad, and the eccentric wheel 6 is connected to the motor output shaft through a belt and a pulley. After the driver 5 is started, the motor starts according to the preset speed curve, driving the eccentric wheel 6 to rotate steadily. The eccentric wheel 6 converts the rotational motion of the motor into the eccentric rotation of the mounting plate 31, and the mounting plate 31 then drives the movable jaw plate 3 and related components to crush the ore. During the crushing process, the motor speed can be changed through frequency conversion speed regulation according to the characteristics of the ore, and the crushing frequency and strength can be adjusted to achieve intelligent crushing control.

[0044] Furthermore, it also includes a support rod 11, which is arranged on the frame 1, and the top plate 10 is fixedly connected to the frame 1 through the support rod 11.

[0045] In the above scheme, one end of the support rod 11 is welded to the frame 1, and a reinforcing rib plate is provided at the welding point to enhance the connection strength; the other end is connected to the top plate 10 by welding. During the operation of the entire crushing device, regardless of whether the hammer rod 8 is hammered or not, the top plate 10 always relies on the support rod 11 to remain fixed. The support rod 11 provides stable support for the top plate 10, and is not affected by external factors such as ore impact and vibration. The support rod 11 provides stable support to ensure the fixed installation of the top plate 10, and provides reliable guide support for the hammer rod 8 to improve the crushing quality.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
