DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In one embodiment, referring to Figures 1 to 10A raw material crushing equipment for refractory material production, comprising a shell 1, the top of the shell 1 is provided with a rotating seat 12, an eccentric shaft 11 and a driving motor 5 through a fixed seat 13, a movable jaw 6 is sleeved on the eccentric shaft 11, and movable jaw plates 13 are arranged on both sides of the movable jaw 6, and fixed jaw plates 10 are arranged on both side walls of the shell 1, and a crushing protrusion 14 is arranged on the side of the movable jaw plate 13 close to the fixed jaw plate 10; a fixed seat 2 15 is installed inside the shell 1, a fixed top block 16 is installed on the top of the fixed seat 2 15, and a movable top block 22 is arranged at the bottom of the movable jaw 6, the position of the movable top block 22 corresponds to the position of the fixed top block 16, and the sides of the movable top block 22 and the fixed top block 16 close to each other are both inclined surfaces; reset mechanisms 7 are arranged at both ends of the eccentric shaft 11 for limiting the position of the movable jaw 6; a screening mechanism 9 is arranged at the bottom of the shell 1 for screening the raw materials crushed by the fixed jaw plate 10 and the movable jaw plate 13.

[0035] The raw material to be crushed is placed between the fixed jaw plate 10 and the movable jaw plate 13; after the driving motor 5 is started, it drives the rotating seat 12 to rotate, thereby driving the eccentric shaft 11 to realize eccentric rotation; the rotation of the eccentric shaft 11 causes the movable jaw 6 to reciprocate around its axis, thereby driving the movable jaw plate 13 to reciprocate up and down. During this process, the raw materials between the fixed jaw plate 10 and the movable jaw plate 13 are subjected to multiple crushing forces such as periodic squeezing, rubbing, and grinding, thereby achieving efficient crushing. At the same time, the raw materials are periodically discharged during the crushing process to ensure that the crushing process is carried out continuously; when the movable jaw 6 is driven downward by the eccentric shaft 11, the inclined surface of the movable top block 22 and the inclined surface of the fixed top block 16 gradually approach and abut against each other. As the movable jaw 6 continues to move downward, the inclined surface of the fixed top block 16 exerts a force on the movable top block 22 and the movable jaw 6, causing the movable jaw 6 to move horizontally along the axial direction of the eccentric shaft 11; when the movable jaw 6 moves upward, the inclined surfaces of the movable top block 22 and the fixed top block 16 gradually move away from each other. At this time, the reset mechanism 7 pushes the two ends of the movable jaw 6 to reset the movable jaw 6 horizontally along the axial direction of the eccentric shaft 11. Through the above-mentioned reciprocating motion, the movable jaw 6 can further realize horizontal reciprocating motion along the axial direction of the eccentric shaft 11 on the basis of up and down and left and right motion; the complex motion trajectory of the movable jaw 6 enables the crushing protrusion 14 to apply multi-angle and multi-directional crushing forces such as squeezing, rubbing, and grinding to the raw materials, effectively improving the crushing efficiency and quality; the crushed raw materials are screened by the screening mechanism 9 to ensure the uniformity of the particle size of the finished product, while improving the screening and discharge efficiency.

[0036] As a preferred embodiment of the present invention, the crushing protrusion 14 is a prism structure, and its upper surface is designed as a plane or an arc surface to enhance the uniform pressure distribution on the raw material; a plurality of reinforcing ribs or tooth-like protrusions are designed on the side of the prism to increase the contact friction with the raw material and improve the crushing efficiency.

[0037] As a preferred embodiment of the present invention, the crushing protrusion 14 is a prism structure, and the geometric shape and size of the crushing protrusion 14 can be optimized according to different raw material characteristics, such as adjusting the prism angle, top area or height to meet the crushing requirements of raw materials with different hardness and particle size.

[0038] As a preferred embodiment of the present invention, the crushing protrusion 14 is a prism structure, and the surface of the crushing protrusion 14 can be coated with a wear-resistant material or hardened to extend the service life and reduce the wear caused by long-term use. The prism structure can also be arranged in combination with the distribution of the movable jaw plate 13 in the shell to ensure that the crushing protrusion 14 can apply multi-point, uniform and efficient crushing force to the raw material during the crushing process.

[0039] As a preferred embodiment of the present invention, the crushing protrusion 14 is a prism structure, and the layout of the crushing protrusion 14 can adopt a staggered arrangement or an array design, so that the raw material is squeezed and crushed in multiple directions and angles in the crushing chamber, thereby further improving the crushing effect.

[0040] As a preferred embodiment of the present invention, the reset mechanism 7 includes a mounting seat 73 installed at both ends of the eccentric shaft 11, and a limiting plate 71 is installed on the side of the mounting seat 73 close to the movable jaw 6 through a telescopic component 72. A spring is arranged between the mounting seat 73 and the limiting plate 71 to form a reset elastic structure. When the movable jaw 6 is pushed by the fixed top block 16 and the movable top block 22 to move axially along the eccentric shaft 11, the limiting plate 71 is subjected to pressure. At this time, the telescopic component 72 cooperates with the spring, and the spring is compressed to absorb energy. At the same time, the telescopic component 72 provides a stable guide for the movement of the limiting plate 71 to avoid lateral shaking or deviation.

[0041] When the fixed top block 16 and the movable top block 22 stop pushing, the spring releases the compressed energy, pushing the limit plate 71 to reset, thereby driving the movable jaw 6 to move horizontally along the axial direction of the eccentric shaft 11 back to the original position. In order to further improve the stability and durability of the reset mechanism, the telescopic component 72 can adopt a hydraulic rod, a pneumatic cylinder or a wear-resistant guide rod structure, and a dust cover is added to the outside to prevent dust from invading and causing wear to the internal moving parts.

[0042] The spring can select a suitable elastic coefficient according to the size and mass of the movable jaw 6 and the movement frequency of the eccentric shaft 11, and optimize its recovery performance through a segmented design or an adjustable compression preload structure. In addition, the surface of the limit plate 71 can be strengthened, such as adding a wear-resistant coating or plating, to cope with wear under long-term stress conditions and ensure the stability of the contact portion with the movable jaw 6.

[0043] In order to achieve more efficient and accurate resetting, the resetting mechanism 7 can be combined with a sensor to monitor the displacement of the limit plate 71 in real time, and adjust the action parameters of the spring and telescopic component 72 through the control unit to ensure that the movable jaw 6 always maintains the accuracy and efficiency of resetting during high-speed movement.

[0044] As a preferred embodiment of the present invention, both ends of the movable jaw 6 close to the limit plate 71 are provided with extension protrusions 8, and the position of the extension protrusions 8 corresponds to the side position of the limit plate 71, ensuring that the limit plate 71 can apply a stable and uniform resetting force to both ends of the movable jaw 6. The extension protrusions 8 are integrally cast or detachably mounted, and are optimized according to the motion trajectory of the movable jaw 6 to ensure that they always maintain precise contact with the limit plate 71.

[0045] In order to enhance the mechanical properties of the extended protrusion 8, the surface of the extended protrusion 8 can be subjected to wear-resistant treatment, such as spraying a hard alloy layer, plating a nickel-phosphorus alloy, or adding ceramic particles, to extend its service life in high-frequency reset action. The geometric shape of the extended protrusion 8 can be optimized according to specific application requirements, such as being set to an arc, trapezoidal or wedge-shaped structure to further improve its matching efficiency and contact stability with the limiting plate 71.

[0046] In order to ensure the rigidity and fatigue resistance of the extended protrusion 8 during the high-speed movement of the movable jaw 6, a reinforcing rib or a hollow weight-reducing structure can be added inside the extended protrusion 8, while maintaining a balance between its strength and lightness. The connection between the extended protrusion 8 and the movable jaw 6 can be designed as an elastic energy-absorbing interface to absorb part of the impact force and reduce the vibration and wear of the movable jaw 6 caused by resetting.

[0047] In addition, the extended protrusions 8 may be arranged in a multi-point distribution or symmetrical arrangement to improve the reset accuracy of the movable jaw 6. In order to further improve the operating efficiency, a rolling bearing or a sliding guide structure may be provided at the contact portion between the side of the limit plate 71 and the extended protrusion 8 to reduce movement resistance and contact wear, while improving the reset sensitivity and the stability of the movable jaw 6.

[0048] As a preferred embodiment of the present invention, both sides of the fixed seat 15 are provided with a movable jaw support structure 18 for supporting the movable jaw plate 13; a through hole 17 is opened on the side of the fixed seat 15, and the movable jaw support structure 18 includes a movable jaw pull plate 182 that is arranged through the through hole 17, and a mounting seat 183 is provided at one end of the movable jaw pull plate 182 away from the movable jaw plate 13, and a buffer spring 184 is installed on the side of the mounting seat 183, and the buffer spring 184 is used to absorb the movable jaw The impact force of the plate 13 during the movement process is reduced, thereby reducing mechanical vibration and wear. A limited fixed seat 19 is installed on the side of the fixed seat 2 15. A through hole 2 is opened on the side of the limited fixed seat 19. The movable jaw pull plate 182 extends through the through hole 2 to the other end of the limited fixed seat 19. A limited component 185 is set. The limited component 185 is fixed by snap, thread or welding to ensure the stability of its position. The limited fixed seat 19 is located between the buffer spring 184 and the limited component 185 to form an elastic limited reset mechanism. When the movable jaw plate 13 reciprocates, the buffer spring 184 is compressed to absorb energy when subjected to external force, and then releases energy to push the movable jaw pull plate 182 to reset, thereby limiting the movement range of the movable jaw plate 13 and ensuring that it runs smoothly within the set range.

[0049] A connecting seat 186 is installed on one side of the movable jaw plate 13 near the second fixed seat 15, which is used to form a stable connection with the movable jaw pull plate 182. A connecting block 181 is fixed to one end of the movable jaw pull plate 182 extending to the connecting seat 186, and the connecting block 181 can be fixed to the connecting seat 186 by bolts, pins or adjustable connections, so as to finely adjust the motion trajectory of the movable jaw plate 13 according to the operation requirements of the equipment.

[0050] In order to enhance the durability and adaptability of the overall structure, the movable jaw plate 182, the buffer spring 184 and related components can be made of high-strength alloy steel or composite materials to improve the impact resistance and corrosion resistance. In addition, the elastic coefficient of the buffer spring 184 can be optimized according to the mass and movement frequency of the movable jaw plate 13, and the initial compression force of the spring can be adjusted by the pre-tightening device when necessary.

[0051] In order to further improve the running stability of the equipment, the outer surface of the movable jaw pull plate 182 can be provided with a lubricating coating or a sliding guide structure to reduce friction, and the inner walls of the through hole 17 and the through hole 2 can be installed with wear-resistant bushings to reduce wear during long-term operation. The overall design of the movable jaw support structure 18 ensures the stability and reliability of the movable jaw plate 13 in reciprocating motion, while reducing the energy loss of the equipment due to inertial impact.

[0052] As a preferred embodiment of the present invention, an adjustment seat 20 is provided on the side where the fixed seat 2 15 and the movable jaw plate 13 are close to each other. The adjustment seat 20 can be firmly connected with the fixed seat 2 15 and the movable jaw plate 13 through bolts, pins or sliding groove structures, and its position can be finely adjusted. The same toggle plate 21 is provided between two adjacent adjustment seats 20. The toggle plate 21 can be connected to the adjustment seat 20 by means of hinged or sliding fit, and is used to accurately limit the movement range of the movable jaw plate 13 to ensure the stability and safety of the equipment operation.

[0053] The shape of the adjustment seat 20 is designed to be a trapezoidal, rectangular or arc-shaped structure, and its contact surface is optimized according to the shape of the toggle plate 21 to improve the fit between the two. The adjustment seat 20 can be provided with an adjustment bolt or a pressure adjustment device, and the user can flexibly change the range of motion of the movable jaw plate 13 by adjusting its tightness or position to meet different crushing requirements.

[0054] The toggle plate 21 is made of high-strength wear-resistant materials, such as alloy steel or composite ceramics, to ensure its strength and durability when subjected to high-frequency reciprocating motion. To enhance the functionality of the toggle plate 21, its surface can be quenched or plated to extend its service life. In addition, the geometry of the toggle plate 21 can be designed as an arch or a bent structure to provide a larger contact area and mechanical stability, thereby effectively dispersing the impact load of the movable jaw plate 13 during movement.

[0055] In order to further improve the reliability of the adjustment seat 20 and the toggle plate 21, a shock-absorbing pad or a sliding guide rail can be added at the connection between the adjustment seat 20 and the fixed seat 2 15 and the movable jaw plate 13 to reduce the loss and noise caused by mechanical vibration and friction. At the same time, the connection between the adjustment seat 20 and the toggle plate 21 can adopt a quick-release or slidable structure design to facilitate maintenance, replacement or adjustment.

[0056] In actual use, the toggle plate 21 can be combined with a sensor or monitoring device to monitor the actual movement amplitude of the movable jaw plate 13 in real time, and feed the data back to the control system for automatically adjusting the position of the adjustment seat 20, thereby further improving the intelligence of the equipment operation and the processing accuracy.

[0057] As a preferred embodiment of the present invention, grooves are provided on both side edges of the movable jaw plate 13, and an extended side plate 23 is installed inside the groove through a spring. The extended side plate 23 extends out from the groove under the push of the spring, and its side edge always maintains close contact with the inner wall of the shell 1. Even when the movable jaw plate 13 moves back and forth axially with the movable jaw 6 along the eccentric shaft 11, the extended side plate 23 can dynamically adjust its position to adapt to changes in the motion trajectory.

[0058] The extended side plate 23 is provided with a spring preload and a limit mechanism to ensure the stability and accuracy of its extension distance, and to avoid the shielding effect being affected by excessive pop-up or retraction. The spring can be made of a high-temperature resistant and highly elastic alloy material to cope with high-frequency movement and long-term use in a high-temperature environment.

[0059] To further improve the functionality of the extended side plate 23, the portion thereof in contact with the groove may be installed with a sliding guide rail or a rolling bearing to reduce friction and improve movement flexibility. The contact surface between the side edge of the extended side plate 23 and the inner wall of the housing 1 is designed to be an arc or a flexible structure, which can further enhance the fit and ensure that there is no gap when crushing the raw materials.

[0060] The surface of the extended side plate 23 can be coated with a wear-resistant coating or a composite material to enhance the wear resistance and service life, while reducing the loss caused by the impact of raw material fragments. A dust cover or a seal can be provided on the inner wall of the groove to prevent dust or fragments from entering the groove and affecting the free movement of the spring and the extended side plate 23.

[0061] In addition, in order to prevent raw material fragments from being stuck between the side of the movable jaw 6 and the inner wall of the shell 1, a scraper or sweeper structure can be set on the side of the extended side plate 23, which can automatically remove residual materials on the inner wall of the shell during each reciprocating motion, further improving the operating reliability of the equipment.

[0062] When necessary, the design of the extended side plate 23 can be linked with the monitoring device to sense in real time the contact state between the inner wall of the housing 1 and the extended side plate 23. If the extended side plate 23 fails to completely fit the inner wall of the housing 1, an alarm signal can be issued or the extension force of the spring can be automatically adjusted to ensure the safety and stability of the operation process.
