Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, and in particular to a high-efficiency long-distance belt conveyor in a horizontal tunnel. Background Art

[0002] With the continuous progress of the mining economy, the resources of easily exploitable limestone open-pit mines are becoming increasingly depleted, while mines with complex terrain and topography are increasing. The traditional road development-car transportation mode is no longer dominant, and the application of adit chute development-belt transportation scheme is becoming more and more widespread. Specifically, the workflow of the current adit chute development-belt transportation scheme is: the ore and rock near the working face are transported to the chute mouth for unloading, the ore and rock are naturally discharged along the chute by their own weight, and are crushed in the chamber at the bottom of the chute, and then directly transported to the cement plant or designated unloading point by belt transportation equipment, forming an efficient joint development method.

[0003] Generally speaking, the existing horizontal chute development-belt transportation scheme is mainly suitable for the discharge of ore. However, when a waste rock dump cannot be set up in a mining site, or there is a large height difference between the waste rock dump and the mining site, it is often necessary to use a chute system to discharge the waste rock. In this case, a waste rock chute and a waste rock crushing chamber must be set up separately, and the waste rock crushing chamber often needs to be independently designed and reasonably constructed according to the actual situation, which undoubtedly greatly increases the mining cost. In response to this problem, the present invention proposes the following solution: the crushing structure is directly integrated into the conveyor belt, thereby eliminating the construction link of the waste rock crushing chamber, realizing the synchronous crushing and transportation of the waste rock, effectively reducing the mining cost, and improving the mining efficiency. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a high-efficiency long-distance belt conveyor in a horizontal tunnel, which realizes multi-stage crushing in the process of stone transportation by integrating clamping crushing, extrusion crushing and rolling crushing components on the gantry. Among them, the pressure of the rolling crushing component is adjustable, and gradually increases with the extrusion action, thereby enhancing the crushing effect. The height of the impact hammer is adjustable, and it cooperates with the rolling crushing component to promote the rotation of the rolling roller and improve the crushing efficiency. The clamping crushing component adopts a movable crushing seat to form a channel for collecting stones, and cooperates with the crushing tooth design to further enhance the crushing capacity.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts a high-efficiency long-distance belt conveyor in a horizontal tunnel, including a conveying mechanism for conveying stones, and several gantries are arranged in sequence above the conveying mechanism along the conveying direction of the conveying mechanism. The gantries are provided with a clamping crushing assembly, an extrusion crushing assembly and a rolling crushing assembly. The rolling pressure of the rolling crushing assembly is adjustable and the rolling pressure of the rolling crushing assembly gradually increases with the downward pressing action of the extrusion crushing assembly.

[0006] As a further optimization of the above scheme, the gantry has vertical plates vertically arranged on both sides of the conveying mechanism, and a horizontal plate is provided between the two vertical plates, which is at a right angle to the vertical plates. The extrusion and crushing assembly includes an impact hammer with an adjustable height arranged under the horizontal plate, and the lifting power mechanism is installed at the input end of the impact hammer.

[0007] As a further optimization of the above scheme, the rolling crushing assembly includes a rotating frame, a rolling roller and an elastic member that are rotatably mounted on a vertical plate. The cantilever end of the rotating frame is connected to the rolling roller, and the stone in the conveying is located on the rolling path of the rolling roller. One end of the elastic member is connected to the horizontal plate and the other end is connected to the rotating frame. The rotating frame rotates under the lifting and lowering action of the impact hammer.

[0008] As a further optimization of the above solution, the number of the rolling crushing assemblies is two, and the two rolling crushing assemblies are symmetrically distributed along the lifting path of the impact hammer.

[0009] As a further optimization of the above solution, a mounting plate is provided between the impact hammer and the lifting power mechanism, and the mounting plate and the impact hammer are detachably matched.

[0010] As a further optimization of the above solution, the clamping and crushing assembly includes two crushing seats that can move perpendicular to the conveying direction of the transportation mechanism, and the two crushing seats enclose a stone channel that can retract, clamp and collect the crushed stone.

[0011] As a further optimization of the above solution, the contact surface of the crushing seat is convexly provided with crushing teeth.

[0012] As a further optimization of the above scheme, the clamping and crushing assembly also includes a square plate, a bending rod and a hinged rod installed on the lifting rod of the lifting power mechanism. Two relatively arranged hinged parts are provided under the square plate. The bending part of the bending rod is hinged to the hinged part. The above-mentioned crushing seat is installed at one end of the above-mentioned bending rod, and the other end of the bending rod is hinged with a hinged rod. One end of the hinged rod is hinged to the horizontal plate.

[0013] As a further optimization of the above solution, the contact surface of the crushing seat is an inclined surface, and the two inclined surfaces cooperate to form a stone channel with a funnel-shaped structure opening upward.

[0014] As a further optimization of the above solution, the clamping and crushing components and the extrusion and crushing components are arranged in sequence along the conveying direction of the conveying mechanism.

[0015] The high-efficiency long-distance belt conveyor in a horizontal tunnel of the present invention has the following beneficial effects: 1. The high-efficiency long-distance belt conveyor in the horizontal tunnel of the present invention realizes multi-stage continuous crushing of stones by arranging several gantries above the conveying mechanism and integrating clamping crushing, extrusion crushing and rolling crushing components, which greatly improves the crushing efficiency and conveying capacity. The rolling pressure of the rolling crushing component is adjustable and gradually increases with the downward pressure of the extrusion crushing component, making the crushing process more flexible and efficient.

[0016] 2. In the high-efficiency long-distance belt conveyor in the horizontal tunnel of the present invention, the height-adjustable impact hammer can accurately control the rotation and crushing force of the rolling roller under the drive of the lifting power mechanism, further improving the crushing effect. At the same time, the two rolling crushing components are symmetrically distributed along the lifting path of the impact hammer, so that the rolling crushing is carried out synchronously with the extrusion crushing, and the two outward rolling crushing structures will evenly distribute the crushed waste rocks, stones, etc. on both sides during the crushing process.

[0017] 3. The high-efficiency long-distance belt conveyor in the horizontal tunnel of the present invention is cleverly equipped with a clamping and crushing assembly, which includes two crushing seats that can flexibly move perpendicular to the conveying direction and enclose a retractable and clamped stone channel, thereby effectively collecting and crushing the stone. Crushing teeth are convexly provided on the contact surface of the crushing seat, thereby significantly enhancing the crushing force and improving the crushing effect.

[0018] 4. In addition, the clamping and crushing components are strategically arranged in front of the extrusion and crushing components, so that they can effectively gather the waste rocks and stones on the transport mechanism to the middle of the transport path, creating convenient conditions for subsequent extrusion and crushing operations. In addition, in conjunction with the rolling crushing components arranged on both sides, the stones after rolling and crushing can be efficiently dispersed to both sides of the transport path, thereby optimizing the distribution of stones and facilitating the subsequent clamping and crushing components to perform re-clamping and stone collection operations. The entire design process is smooth and efficient.

[0019] 5. In the high-efficiency long-distance belt conveyor in a horizontal tunnel of the present invention, the clamping and crushing components, the extrusion and crushing components and the rolling and crushing components are all integrated and installed on the same lifting power mechanism, realizing a complete ascending and descending process, and sequentially performing the actions of clamping and crushing and stone gathering, extrusion and crushing, rolling and crushing and stone dispersion. Specifically, in the ascending action stage, the extrusion and crushing components move upward and store energy, while the rolling and crushing components are reset under the action of the elastic member. At this time, the clamping and crushing components are started to clamp and crush the stones and waste rocks in the stone channel, and at the same time gather the crushed stones to the middle of the conveying path. Entering the descending action stage, the extrusion and crushing components are pressed downward to implement the extrusion and crushing operation; at the same time, during the descent process, the two rolling and crushing components are squeezed to both sides to complete the rolling and crushing and disperse the stones, preparing for the next round of clamping and crushing component operations.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0024] It should be noted that when an element is referred to as being "disposed on, provided with" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items. Please refer to the instruction manual Figure 1-10 The present invention provides a first embodiment of a high-efficiency long-distance belt conveyor in a horizontal tunnel. The core structure of the belt conveyor in this embodiment includes a conveying mechanism 1 responsible for conveying stones, a gantry 2, a clamping crushing component 3, an extrusion crushing component 4 and a rolling crushing component 5. The specific situation is as follows: Conveying mechanism 1, in this embodiment, the conveying mechanism 1 is installed in a waste rock transport horizontal shaft, in which there is a ore bin or a waste rock bin receiving the bottom of the chute, connecting the ore bin or the waste rock bin with the surface or the waste rock yard at the unloading point. Preferably, in this embodiment, the conveying mechanism 1 uses a belt conveyor, and in this embodiment, it is preferred that a protective cover is installed at the dangerous part of the belt conveyor, and at the same time, the staff is prohibited from staying under the belt conveyor. In particular, in this embodiment, the suspended height of the belt conveyor is limited to less than 2m.

[0026] The gantry 2, in this embodiment, is composed of vertical plates 21 vertically arranged on both sides of the conveying mechanism 1, the bottom of the vertical plates 21 is locked to the ground of the tunnel by structures such as anchor bolts, and a horizontal plate 22 is provided between the two vertical plates 21 at a right angle thereto. Furthermore, in order to strengthen the structural strength of the gantry 2, some reinforcing ribs and other structures can be added to the gantry 2.

[0027] Extrusion and crushing assembly 4. In this embodiment, the extrusion and crushing assembly 4 includes a lifting power mechanism 42 and an impact hammer 41. Specifically, the height-adjustable impact hammer 41 is arranged below the horizontal plate 22. The power end of the lifting power mechanism 42 is connected to the impact hammer 41, and the lifting power mechanism 42 provides power for the impact hammer 41 and drives the impact hammer 41 to perform lifting and lowering motion in the vertical direction.

[0028] Preferably, in some examples, the lifting power mechanism 42 adopts a lifting cylinder. Of course, a lifting method such as a screw moving seat can also be adopted. In the present embodiment, the lifting cylinder is installed above the horizontal plate 22. The cylinder rod of the lifting cylinder passes through the horizontal plate 22 and extends downward for a distance. The lifting hammer is installed on the cylinder rod.

[0029] It should be noted that, in this embodiment, the lifting rod 421 in the lifting power mechanism 42 is the cylinder rod.

[0030] In some implementation examples, a detachable design is adopted to facilitate the disassembly and assembly of the impact hammer 41. This embodiment proposes a preferred solution: a mounting plate 43 is arranged at one end of the lifting rod 421 close to the impact hammer 41, and a slide groove is arranged below the mounting plate 43. The slide groove is designed as a trapezoidal structure with a wide top and a narrow bottom to accommodate the sliding of the impact hammer 41. Matching thread grooves are arranged on one side of the slide groove and on the impact hammer 41. The locking screw passes through the two thread grooves in sequence to achieve a stable locking of the mounting plate 43 and the impact hammer 41.

[0031] This structural design simplifies the disassembly and assembly process: the locking state of the impact hammer 41 can be released by simply rotating the locking screw. Then, the impact hammer 41 to be replaced can be slid out along the slide groove. Then, the new impact hammer 41 can be slid into the slide groove, and after the two thread grooves are aligned, the impact hammer 41 can be easily replaced by locking the locking screw.

[0032] Further optimization, a limit baffle is provided on one side of the chute to limit the sliding position of the impact hammer 41. When the impact hammer 41 slides to the limit baffle, it is positioned to ensure the accurate installation position of the impact hammer 41 in the chute.

[0033] The rolling crushing assembly 5 is composed of a rotating frame 51, a rolling roller 52 and an elastic member 53. In this embodiment, the rotating frame 51 is rotatably mounted on the vertical plate 21. Specifically, two symmetrical connecting plates are provided on the vertical plate 21, and connecting holes corresponding to the positions are provided on the connecting plates. A first rotating shaft is passed through one end of the rotating frame 51, and both ends of the shaft pass through the rotating frame 51 and the connecting holes to realize the rotation of the rotating frame 51. The other end of the rotating frame 51 is recessed inward to form a recessed portion, and through holes are provided on both sides of the recessed portion. The second rotating shaft passes through the through holes and rotatably cooperates with the rolling roller 52, and the rolling roller 52 is located on the lifting path of the impact hammer 41.

[0034] In order to realize the reset of the rotating frame 51, in this embodiment, an elastic member 53, preferably a tension spring, is connected to the middle of the rotating frame 51. The other end of the tension spring is connected to the horizontal plate 22, so that the rotating frame 51 is kept in the upward pulling state under normal conditions. Only when the impact hammer 41 is pressed down, the rotating frame 51 is squeezed to rotate, thereby realizing the simultaneous extrusion crushing, rolling crushing and stone dispersion, effectively improving the stone crushing effect. When the impact hammer 41 moves upward, the rotating frame 51 is restored to the upward pulling state under the action of the restoring force of the elastic member 53.

[0035] In addition, in some embodiments, in order to further improve the crushing effect, two rolling crushing assemblies 5 are provided on the same gantry 2, which are respectively placed on both sides of the impact hammer 41, and the rolling rollers 52 in the two assemblies are both located on the lifting path of the impact hammer 41.

[0036] This embodiment provides a high-efficiency long-distance belt conveyor in a horizontal tunnel, and the working process is as follows: The ore bin or waste rock bin receives the rocks falling from the chute, and the workers use transportation tools to load the rocks onto the belt conveyor. The belt conveyor runs continuously to transport the rocks or waste rocks to the predetermined location.

[0037] During this period, the lifting power mechanism 42 (such as a lifting cylinder) is in the preparation stage, providing power for the vertical lifting movement of the impact hammer 41. When the stone arrives at the designated crushing position, the lifting power mechanism 42 starts to drive the impact hammer 41 downward. The impact hammer 41 hits the stone at a predetermined speed and force to complete the initial extrusion and crushing of the stone.

[0038] Immediately or subsequently, the stone material contacts the rolling roller 52. Under the squeezing action of the impact hammer 41, the stone material is pushed toward the rolling roller 52. The rolling roller 52 starts to rotate under the drive of the rotating frame 51, and further crushes and crushes the stone material to make it more finely broken. At the same time, the rotation of the rolling roller 52 helps to disperse the stone material and prevent it from piling up.

[0039] After the impact hammer 41 completes the extrusion and crushing, the lifting power mechanism 42 drives it upward and returns to the initial position. Under the restoring force of the elastic member 53 (such as a tension spring), the rotating frame 51 and the rolling roller 52 also return to the initial state, ready for the next crushing.

[0040] The conveying mechanism 1 continues to operate to convey the stone materials that have undergone multiple crushing processes to the next process or unloading point.

[0041] In summary, the stone transportation and crushing process in this embodiment is a continuous and efficient process. Through the coordinated action of the conveying mechanism 1, the extrusion crushing component 4 and the rolling crushing component 5, the rapid and effective crushing and transportation of the stone is achieved.

[0042] Please refer to the instruction manual Figure 1-10The present invention provides a second embodiment of a high-efficiency long-distance belt conveyor in a horizontal tunnel. In this embodiment, the above-mentioned belt conveyor is further enhanced in crushing effect based on the original structure. The specific structure is as follows: In this embodiment, the belt conveyor includes a conveying mechanism 1 for conveying stones. A plurality of gantries 2 are sequentially arranged above the conveying mechanism 1 along the conveying direction of the conveying mechanism 1. The gantries 2 are provided with a clamping crushing assembly 3, an extrusion crushing assembly 4 and a rolling crushing assembly 5. The rolling pressure of the rolling crushing assembly 5 is adjustable and the rolling pressure of the rolling crushing assembly 5 gradually increases with the downward pressing action of the extrusion crushing assembly 4.

[0043] Furthermore, the gantry 2 has vertical plates 21 vertically arranged on both sides of the conveying mechanism 1, a horizontal plate 22 is arranged between the two vertical plates 21 and is at a right angle to the vertical plates 21, a height-adjustable impact hammer 41 is arranged under the horizontal plate 22, and a lifting power mechanism 42 is installed at the input end of the impact hammer 41.

[0044] Furthermore, the rolling crushing assembly 5 includes a rotating frame 51, a rolling roller 52 and an elastic member 53 which are rotatably mounted on the vertical plate 21. The rolling roller 52 is connected to the cantilever end of the rotating frame 51, and the stone in the conveying is located on the rolling path of the above-mentioned rolling roller 52. One end of the elastic member 53 is connected to the horizontal plate 22 and the other end is connected to the rotating frame 51. The rolling roller 52 is located on the lifting path of the impact hammer 41 and rotates under the lifting action of the impact hammer 41.

[0045] Furthermore, the number of the rolling crushing assemblies 5 is two, and the two rolling crushing assemblies 5 are symmetrically distributed along the lifting path of the impact hammer 41 .

[0046] Furthermore, a mounting plate 43 is provided between the impact hammer 41 and the lifting power mechanism 42 , and the mounting plate 43 and the impact hammer 41 are detachably matched.

[0047] Furthermore, in this embodiment, the clamping and crushing assembly 3 is designed with two crushing seats 31, and the two crushing seats 31 can move perpendicular to the conveying direction of the conveying mechanism. The two crushing seats 31 are enclosed and can be retracted to clamp and crush the stone, and at the same time, the stone is collected into the stone channel 32.

[0048] In some embodiments, the movement of the crushing seat 31 is achieved by two horizontal cylinders. Specifically, the horizontal cylinder is fixedly mounted on the vertical plate, and the cylinder rod of the horizontal cylinder is connected to the crushing seat 31. Through the power provided by the horizontal cylinder, the cylinder rod performs a telescopic action, during which the crushing seat 31 is driven to perform a clamping and crushing action in the horizontal direction, thereby achieving effective crushing of the stone.

[0049] In order to further improve the crushing effect, a crushing tooth 311 is convexly provided on the contact surface of the crushing seat 31, and the crushing capacity is enhanced by the crushing tooth 311. Preferably, the crushing tooth 311 is a conical structure in this embodiment and the sharp part of the crushing tooth 311 faces the stone, so that during the contraction and clamping action of the above-mentioned crushing seat 31, the crushing tooth 311 can effectively gather the above-mentioned stone and clamp and crush the above-mentioned stone.

[0050] In order to optimize the introduction and crushing efficiency of stones, the contact surface of the crushing seat 31 is designed as an inclined surface. The two inclined surfaces cooperate with each other to form a funnel-shaped stone channel 32 with an opening facing upward. This design facilitates the gathering and crushing of stones. During the crushing process, the bottom stones are first clamped and crushed. Thanks to the inclined structure of the inclined surface, part of the stones below enter the upper area under the action of gravity. Subsequently, the crushing seat 31 performs a clamping and crushing action again to crush this part of the stones for the second time, thereby significantly improving the overall effect of clamping and crushing.

[0051] In this embodiment, the movement of the crushing seat 31 is mainly achieved by the movement of the lifting rod 421. Specifically, the clamping crushing assembly 3 also includes a square plate 33, a bending rod 34 and a hinge rod 35, which are installed on the lifting rod 421 of the lifting power mechanism 42. Two hinged parts 331 arranged opposite to each other are provided below the square plate 33, and the bending part of the bending rod 34 is hinged thereto. The crushing seat 31 is installed at one end of the bending rod 34, and the other end of the bending rod 34 is hinged with the hinge rod 35, and one end of the hinge rod 35 is hinged on the horizontal plate 22, forming a stable mechanical structure.

[0052] In addition, the clamping crushing assembly 3 and the squeezing crushing assembly 4 are arranged in sequence along the conveying direction of the transport mechanism, thereby achieving orderly and efficient crushing of the stone.

[0053] This embodiment provides a high-efficiency long-distance belt conveyor in a horizontal tunnel, and the working process is as follows: The stones are continuously transported by the conveying mechanism 1 (belt conveyor). Several gantries 2 are arranged in sequence along the conveying direction above the conveying mechanism 1. Each gantry 2 is integrated with a clamping crushing component 3, an extrusion crushing component 4 and a rolling crushing component 5, which are used to gradually crush the stones during the conveying process. Specifically: Initial state and rising action stage: the extrusion and crushing component 4 is in an ascending state, storing energy and preparing to press down.

[0054] The rolling crushing assembly 5 is in a reset state under the action of the elastic member 53, and the rolling roller 52 does not apply pressure to the stone.

[0055] The clamping and crushing assembly 3 is started, and the two crushing seats 31 move toward the middle under the drive of the lifting power mechanism 42, clamping and crushing the stones and waste stones in the stone channel 32. The crushing teeth 311 effectively gather and crush the stones, and the inclined surface design allows the bottom stones to be clamped and crushed first, and part of the stones enter the upper area under the action of gravity for secondary crushing.

[0056] The crushed stones are gathered in the middle of the conveying path, ready to enter the next crushing stage.

[0057] Descending stage: the extrusion and crushing assembly 4 is driven downward by the lifting power mechanism 42 to perform an extrusion and crushing operation on the stone.

[0058] At the same time, during the descent, the two rolling crushing assemblies 5 are squeezed to both sides. Since the rolling roller 52 is located on the lifting path of the impact hammer 41, the downward pressure of the impact hammer 41 causes the rolling roller 52 to rotate and roll the stone. The rolling pressure is adjustable and gradually increases with the downward pressure of the squeezing and crushing assembly 4.

[0059] The symmetrical distribution of the rolling crushing assembly 5 ensures that the stone is evenly rolled and crushed, while the rotation of the rolling roller 52 helps to disperse the stone, preparing for the next round of clamping and crushing assembly 3 operation.

[0060] Circular crushing: With the continuous operation of the conveying mechanism 1, the stone is subjected to the cyclic crushing treatment of the clamping crushing component 3, the squeezing crushing component 4 and the rolling crushing component 5 in turn.

[0061] At each gantry 2, the stone undergoes actions such as clamping crushing and stone gathering, extrusion crushing, rolling crushing and stone dispersion, achieving efficient and orderly crushing processing.

[0062] Therefore, the present invention integrates the clamping crushing assembly 3, the extrusion crushing assembly 4 and the rolling crushing assembly 5 on the same lifting power mechanism 42, so as to achieve synchronization and coordination of the movements. The movement of the crushing seat 31 of the clamping crushing assembly 3 is achieved by the movement of the lifting rod 421, forming a stable mechanical structure. The conical structure and inclined surface design of the crushing teeth 311 improve the crushing efficiency and effect. The rolling pressure of the rolling crushing assembly 5 is adjustable, and gradually increases with the downward pressing action of the extrusion crushing assembly 4, which enhances the adaptability and flexibility of crushing.

[0063] The high-efficiency long-distance belt conveyor in the horizontal tunnel of this embodiment integrates the clamping crushing, extrusion crushing and rolling crushing components 5, and performs each crushing action in sequence in a complete ascending and descending process, thereby realizing efficient and orderly crushing of stones during the transportation process.

[0064] In summary, in this embodiment, the clamping crushing assembly 3, the extrusion crushing assembly 4 and the rolling crushing assembly 5 are all integrated and installed on the same lifting power mechanism 42, ensuring that various crushing actions can be performed in an orderly manner in a complete lifting cycle process. Specifically, the process includes key steps such as clamping crushing and stone collection, extrusion crushing, rolling crushing and stone dispersion.

[0065] During the ascending action phase, the extrusion crushing assembly 4 moves upward with the lifting power mechanism 42, while accumulating energy to prepare for the subsequent extrusion crushing operation. At the same time, the rolling crushing assembly 5 automatically resets under the action of the elastic member 53, ensuring that the rolling roller 52 is in the initial state, providing conditions for the next rolling crushing operation. At this time, the clamping crushing assembly 3 starts working, effectively clamping and crushing the stones and waste rocks in the stone channel 32. After the crushing is completed, the assembly will also gather the crushed stones to the middle of the conveying path, providing convenience for the subsequent crushing process.

[0066] Entering the descending stage, the squeezing and crushing assembly 4 is driven by the lifting power mechanism 42 to press down and perform squeezing and crushing operations on the stone. At the same time, during the descending process, the two rolling and crushing assemblies 5 are squeezed to both sides, and the rolling rollers 52 roll and crush the stone. This process not only completes the rolling and crushing of the stone, but also disperses the stone to an appropriate position, creating favorable conditions for the next round of clamping and crushing assembly 3 operations.

[0067] During the entire lifting and lowering cycle, the crushing components work closely together and move in a coordinated manner, achieving efficient and orderly crushing of stones.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
