Description

Technical Field

[0001] This invention relates to the field of mineral and rock processing technology, and specifically to a crushing device based on mineral and rock processing. Background Technology

[0002] In the field of mineral and rock processing, crushing is a crucial pre-processing step before subsequent grinding, sorting, and utilization. Its crushing efficiency and effect directly affect the capacity and product quality of the entire mineral and rock processing production line. Currently, jaw crushers are widely used in the industry for crushing medium-hard and harder ores. These devices have become the mainstream equipment in mining, construction, and building materials industries due to their relatively simple structure, high crushing strength, and wide applicability to various types of ores.

[0003] Traditional devices rely on springs to achieve the return thrust of the movable jaw plate. During high-frequency reciprocating force, the springs are prone to fatigue wear, elasticity decay, or even breakage, resulting in untimely reset of the movable jaw plate and unstable crushing gap. This not only reduces crushing efficiency but also requires frequent shutdowns to replace the springs, increasing maintenance costs and the risk of operational interruption. The swing fulcrum is mostly designed with a fixed design, and the swing trajectory is simple and the amplitude is fixed. On the one hand, the movable jaw plate lacks the space for vertical adjustment during swing, which can easily cause motion interference due to uneven ore particle size or hardness fluctuations, resulting in jaw plate jamming. On the other hand, the fixed swing amplitude cannot adapt to ores with different hardness (such as soft rock and hard rock) and different crushing particle size requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a crushing device based on ore and rock processing to solve the problems existing in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions: A crushing device based on ore and rock processing includes a base plate, a frame securely mounted on the base plate, and a crushing mechanism embedded inside the frame. The crushing mechanism includes: The jaw plate is fixed and mounted on one side of the frame; The movable jaw guard plate is rotatably connected to the fixed axis surface at one end and hinged to the outer connecting frame at the other end. The movable jaw plate is fitted inside the movable jaw guard and is positioned opposite to the fixed jaw plate. Two sets of connecting rods are symmetrically arranged, with one end of the outer side hinged to the other end of the outer connecting frame; The inner connecting frame is hinged to the inner sides of the two sets of connecting rods on both front sides, and hinged to the inner sides of the frame on both rear sides. When the connecting rod swings up and down in an arc, it can drive the moving jaw guard plate and the movable jaw plate to swing back and forth along the fixed axis, thereby squeezing and fracturing the ore between the fixed jaw plate and the movable jaw plate.

[0006] As a further aspect of the present invention: the crushing mechanism is also equipped with two symmetrically distributed moving blocks, which slide in the grooves on both sides of the frame respectively, and the fixed shaft is fixedly connected to the middle of the two moving blocks.

[0007] As a further aspect of the present invention: the inner side of the movable jaw guard is provided with a wedge-shaped block, which forms a sliding connection with the wedge-shaped groove on one side of the movable jaw plate.

[0008] As a further aspect of the present invention, an adjustment mechanism is installed on the inner side of the other end of each of the two sets of connecting rods, thereby realizing the adjustment of the swing amplitude of the connecting rods.

[0009] As a further aspect of the present invention: the adjustment mechanism includes a fixed disk, which is fixedly connected to the end of the transmission shaft, and a miniature motor for driving a threaded screw is fixedly installed in the groove inside the disk. The slider is threadedly connected to the surface of the threaded screw; one side of the connecting plate is fixed to the surface of the slider, and the middle of the other side is hinged to the inner side of the other end of the connecting rod.

[0010] As a further embodiment of the present invention: the threaded screw is movably installed inside the fixed plate, and the slider is slidably connected in the groove inside the fixed plate, and the size of the groove is smaller than the radius of the fixed plate.

[0011] As a further embodiment of the present invention: a drive motor for driving a small pulley is fixedly mounted on the substrate, and a transmission belt is connected to the outer circle of the drive motor. The transmission belt rests on the top of the tightening shaft and forms a transmission connection with the large pulley. The large pulley is fixed to the middle of the small pulley, while the small pulley rotates at one end of the limiting brackets on both sides of the large pulley.

[0012] As a further aspect of the present invention: both sides of the tightening shaft are provided with a moving mechanism for realizing the tensioning operation of the transmission belt.

[0013] As a further aspect of the present invention: the moving mechanism includes: The sliding block slides within the groove of the base plate, and a tightening shaft is rotatably connected inside it; A positioning plate is fixedly attached to the outer surface of the base plate, and a threaded post is rotatably connected to its middle part, with one end of the threaded post fixedly connected to the knob. An extension plate is fixed to one side of the sliding block and threaded to the surface of the threaded column.

[0014] As a further aspect of the present invention: a protective box is fixedly connected to one side of the frame, and a dustproof net is provided on one side of the protective box; The substrate has a discharge groove on one side between the fixed jaw plate and the movable jaw plate, and support legs are installed around the bottom of the substrate. A fixing block is fixedly connected to the inner side of the frame, and one end of the fixing block is fixedly connected to the limiting frame.

[0015] The beneficial effects of this invention are: (1) This invention abandons the traditional spring reverse thrust design and adopts a linkage structure between the outer connecting frame and the inner connecting frame. The moving jaw guard plate and the movable jaw plate are directly driven to swing back and forth along the fixed axis by the up and down arc swing of the connecting rod. This structure does not require the participation of springs in reverse thrust, which completely solves the problems of spring fatigue wear and elastic decay, reduces the replacement frequency of vulnerable parts, and reduces maintenance costs. At the same time, the linkage transmission of the connecting rod is more stable, ensuring timely reset of the movable jaw plate and uniform crushing gap, effectively improving crushing efficiency and consistency of crushed rock particle size. (2) The present invention provides sliding moving blocks in the sliding grooves on both sides of the frame and fixes the fixed shaft to the middle of the moving blocks, so that the moving jaw guard plate has a space for vertical movement when it drives the moving jaw plate to swing: on the one hand, the vertical position of the moving jaw plate can be adaptively adjusted according to the crushing thrust, avoiding motion interference caused by fluctuations in the particle size or hardness of the ore; on the other hand, the vertical movement trend combined with the reciprocating swing can form a composite force of compression and shearing on the ore, significantly improving the crushing effect, especially suitable for crushing medium-hard and above hardness ores; (3) By adding an adjustment mechanism to the end of the connecting rod, the present invention can drive the threaded screw to rotate through a micro motor, thereby moving the slider and connecting plate along the groove of the fixed plate, adjusting the eccentric distance between the connecting plate and the fixed plate, and thus changing the swing amplitude of the connecting rod. This design allows the swing amplitude of the movable jaw plate to be flexibly adjusted according to the hardness or crushing particle size requirements of the ore, and can be adapted to crushing operations of different types of ore without changing the equipment, greatly improving the versatility of the device.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figures 1-8 As shown, the present invention is a crushing device based on ore and rock processing, comprising a base plate 1, a frame 2 securely mounted on the base plate 1, and a crushing mechanism 3 embedded inside the frame 2; Crushing mechanism 3 includes: The fixed jaw plate 30 is fixedly mounted on one side of the frame 2; The movable jaw guard plate 31 is rotatably connected at one end to the surface of the fixed shaft 34, and at the other end is hinged to the outer connecting frame 35. The movable jaw plate 32 is fitted inside the movable jaw guard plate 31 and is positioned opposite to the fixed jaw plate 30. Two sets of connecting rods 36 are symmetrically arranged, with one end of the outer side hinged to the other end of the outer connecting frame 35. The inner connecting frame 37 is hinged to the inner sides of the two sets of connecting rods 36 on both front sides, and hinged to the inner sides of the frame 2 on both rear sides. When the connecting rod 36 swings up and down in an arc, it can drive the moving jaw guard plate 31 and the movable jaw plate 32 to swing back and forth along the fixed axis 34, thereby squeezing and fracturing the ore between the fixed jaw plate 30 and the movable jaw plate 32.

[0021] It should be noted that the top of frame 2 is provided with an opening to facilitate the entry of ore and rock materials; Both the fixed jaw plate 30 and the movable jaw plate 32 are provided with biting teeth on their inner sides to facilitate the crushing of ore and rock.

[0022] Example 2 This illustrates yet another embodiment of the invention based on Embodiment 1, therefore repeated parts will not be described again.

[0023] Preferably, in this invention, the crushing mechanism 3 is further equipped with two symmetrically distributed moving blocks 33, which slide in the grooves on both sides of the frame 2 respectively, and the fixed shaft 34 is fixedly connected to the middle of the two moving blocks 33.

[0024] It should be noted that the setting of the moving block 33 allows the moving jaw guard 31 to have a certain vertical movement space when it swings with the movable jaw plate 32, which increases the swing amplitude and moves up and down according to the thrust, and can avoid interference caused by insufficient movement.

[0025] Preferably, the inner side of the movable jaw guard plate 31 is provided with a wedge-shaped block, which forms a sliding dock with the wedge-shaped groove on one side of the movable jaw plate 32.

[0026] Preferably, in this invention, an adjustment mechanism 4 is installed on the inner side of the other end of each of the two sets of connecting rods 36, so as to adjust the swing amplitude of the connecting rods 36.

[0027] Preferably, in this invention, the adjusting mechanism 4 includes a fixed disk 41, which is fixedly connected to the end of the transmission shaft 16, and a micro motor 43 for driving the threaded screw 44 is fixedly installed in the groove inside the disk. The slider 45 is threadedly connected to the surface of the threaded screw 44; one side of the connecting plate 42 is fixedly connected to the surface of the slider 45, and the middle of the other side is hinged to the inner side of the other end of the connecting rod 36.

[0028] It should be noted that the connecting plate 42 is always offset from the center of the fixed plate 41, so that the fixed plate 41 and the connecting plate 42 combine to rotate eccentrically.

[0029] Preferably, in this invention, the threaded screw 44 is movably installed inside the fixed disk 41, and the slider 45 is slidably connected in the groove inside the fixed disk 41, and the size of the groove is smaller than the radius of the fixed disk 41.

[0030] Preferably, in this invention, a drive motor 5 for driving a small pulley 15 is fixedly mounted on the substrate 1, and a transmission belt 6 is connected to the outer circle of the drive motor 5. The transmission belt 6 rests on the top of the tightening shaft 7 and forms a transmission connection with the large pulley 8. The large pulley 8 is fixed to the middle of the small pulley 15, while the small pulley 15 rotates at one end of the limit brackets 17 on both sides of the large pulley 8.

[0031] In the implementation process, the ore to be crushed is placed between the fixed jaw plate 30 and the movable jaw plate 32. A drive motor 5 is set up. The output end of the drive motor 5 drives the small pulley 15 for transmission. The small pulley 15 drives the transmission belt 6 for transmission. The other end of the transmission belt 6 drives the large pulley 8 to rotate. The large pulley 8 drives the central transmission shaft 16 to rotate along the middle of the limit frame 17. The two ends of the transmission shaft 16 drive the eccentric structure composed of the fixed plate 41 and the connecting plate 42 to rotate respectively. The connecting rods 36 on both sides swing up and down with the rotation of the fixed plate 41 and the connecting plate 42. The connecting rods 36 pull the outer connecting frame 35 and the inner connecting frame 37 up and down. The other end of the outer connecting frame 35 pulls the movable jaw guard plate 31. The movable jaw guard plate 31 drives the movable jaw plate 32 to swing back and forth along the fixed axis 34 to squeeze the inner ore and crush it. The movable jaw plate 32 can swing back and forth through the connecting rods 36, reducing the traditional spring back push method and maintaining the crushing effect. When the movable jaw guard plate 31 is pushed and pulled by the outer connecting frame 35, the thrust moves up or down along the slide groove through the moving blocks 33 on both sides of the fixed shaft 34, causing the movable jaw plate 32 to move up and down during the reciprocating swing, thereby increasing the effect of rock and mineral crushing. When it is necessary to adjust the swing amplitude of the movable jaw plate 32, a micro motor 43 is provided. The output end of the micro motor 43 drives the threaded screw 44 to rotate along the middle of the fixed plate 41. The rotation of the threaded screw 44 causes the slider 45 to move up or down along the groove opened on the inner side of the threaded screw 44 and the fixed plate 41. One side of the slider 45 moves the connecting plate 42, thereby adjusting the eccentric distance between the connecting plate 42 and the fixed plate 41, which in turn increases the swing amplitude of the connecting rod 36, thereby improving the swing amplitude of the movable jaw plate 32.

[0032] Example 3 This illustrates yet another embodiment of the present invention based on Embodiment 1 and Embodiment 2, therefore repeated parts will not be described again.

[0033] Preferably, in this invention, both sides of the tensioning shaft 7 are provided with a moving mechanism 9 for tensioning the transmission belt 6.

[0034] Preferably, in this invention, the moving mechanism 9 includes: The sliding block 90 slides in the groove of the base plate 1, and the tightening shaft 7 is rotatably connected inside it; Positioning plate 93 is fixedly attached to the outer surface of base plate 1, and a threaded post 92 is rotatably connected to its middle part. One end of the threaded post 92 is fixedly attached to the knob 94. The extension plate 91 is fixed to one side of the sliding block 90 and threaded to the surface of the threaded post 92.

[0035] Preferably, in this invention, a protective box 11 is fixedly connected to one side of the frame 2, and a dustproof net 12 is provided on one side of the protective box 11; A discharge groove 10 is provided on one side of the substrate 1 located between the fixed jaw plate 30 and the movable jaw plate 32, and support legs 14 are installed around the bottom of the substrate 1. A fixing block 13 is fixedly connected to the inner side of the frame 2, and one end of the fixing block 13 is fixedly connected to the limiting frame 17.

[0036] It should be noted that the dustproof net 12 allows the internal drive motor 5 to dissipate heat naturally through the dust removal groove and also serves as a dustproof function.

[0037] During implementation, when the tension of the transmission belt 6 needs to be adjusted, rotate the two sets of knobs 94. The knobs 94 rotate the threaded column 92 along the middle of the positioning plate 93. The rotation of the threaded column 92 causes the extension plate 91 to move upward along the slide block 90 along the groove opened in the frame 2. The slide block 90 moves upward along the tightening shaft 7. The upward movement of the tightening shaft 7 pushes the transmission belt 6 to tighten the transmission belt 6, thereby ensuring the stability of the transmission.

[0038] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
