UTILITY MODEL CONTENTS
[0004] The utility model aims at providing a kind of broken stone machine that can separate ore to solve the problems raised in the above background.

[0006] Further, the top of base is fixedly installed with L-shaped support frame, the servo motor is arranged at the top of L-shaped support frame, the outside of L-shaped support frame is provided with protective cover, and the protective cover is fixedly installed at the top of L-shaped support frame.
[0007] Furthermore, a feed hopper is fixedly installed on the top of the shell, and a discharge pipe is fixedly installed on the outer circumferential wall of the shell. The screening screen is inclined from the feed hopper toward the discharge pipe.
[0008] Furthermore, a mounting plate is fixedly connected to the outer circumferential wall of the housing, and two elastic plates are fixedly installed between the mounting plate and the base, with the two elastic plates arranged symmetrically.
[0009] Furthermore, a first crushing device is fixedly installed at the bottom of the base, and a second crushing device is provided on one side of the first crushing device, with the second crushing device located below the discharge pipe.
[0010] Furthermore, the cross-section of the first semi-cylinder is configured as a U-shaped block.
[0011] Furthermore, multiple square blocks are provided on one side of both the first and second semi-cylinders, and multiple fixing bolts are threaded onto one side of each square block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this utility model, the operator starts the servo motor via a microcontroller command. Crushed stone is fed from the hopper into the housing. The servo motor drives the connecting rod and rotating rod to rotate at a constant speed. The rotating rod contacts the first semi-cylinder, causing sliding contact and collision. The rotating rod applies a pushing force, and the return spring and elastic plate generate a reaction force, resulting in regular horizontal vibration. The rotating rod continues to rotate, rubbing and colliding with the first semi-cylinder and applying an upward pushing force to the second semi-cylinder. Combined with the cooperation of the return spring and elastic plate, this causes the housing to vibrate vertically periodically. This cycle repeats, causing the housing to vibrate in multiple directions, allowing the crushed stone to tumble and collide multiple times in a short period, accelerating the screening of small particles. The crushed stone is rearranged and layered, ensuring screening opportunities regardless of the feed volume. Even with a large amount of crushed stone entering the housing, it can be quickly dispersed and screening can begin, resulting in high efficiency.
[0014] 2. In this utility model, the number of square blocks can be flexibly adjusted by the operator according to work requirements. When the number of square blocks is increased, the relative spatial arrangement of the rotating rod and the first and second semi-cylinders greatly increases the contact area. Under the same operating conditions, the thrust of the rotating rod on both is significantly increased. Through the coordinated action of the elastic system composed of the return spring and the elastic plate, the force on the shell increases, and the vibration amplitude is significantly increased. By adjusting the number of square blocks, the vibration characteristics of the shell can be effectively changed to adapt to different types of ore. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 This utility model provides a technical solution:
[0023] See Figures 1-5 As shown, a stone crusher capable of separating ore includes a base 1, a housing 2, a servo motor 3 disposed above the housing 2; a connecting rod 4 fixedly connected to the drive end of the servo motor 3; a rotating rod 5 fixedly installed on the outer circumferential wall of the connecting rod 4 near its bottom end; two first semi-cylinders 6 connected to the inner wall of the housing 2; two second semi-cylinders 7 installed on the inner wall of the housing 2; two return springs 9 fixedly installed between the base 1 and the housing 2; and a screening screen 14 fixedly installed on the inner circumferential wall of the housing 2.
[0024] First, the staff uses a microcontroller to issue a command to start the servo motor 3. Then, the crushed stone is conveyed from the feed hopper 17 into the housing 2. The drive end of the servo motor 3 starts to drive the connecting rod 4 and the rotating rod 5 to rotate at a constant speed. When the rotating rod 5 comes into contact with the first semi-cylinder 6 during rotation, a sliding contact phenomenon will occur due to the relative motion between the two. At the moment when the rotating rod 5 collides with the first semi-cylinder 6, the rotating rod 5 will apply a pushing force in a specific direction to the first semi-cylinder 6. At this time, the return spring 9 and the elastic plate 10 interact with the pushing force and generate a reaction force due to their own elastic properties, thereby causing the entire structure to form a regular vibration in the horizontal direction.
[0025] Meanwhile, as the rotating rod 5 continues to rotate, it will continuously slide, rub, and collide with the first semi-cylinder 6. Furthermore, during the rotation, the rotating rod 5 will also apply an upward lifting force to the second semi-cylinder 7. After the second semi-cylinder 7 is subjected to this force, combined with the coordinated action of the return spring 9 and the elastic plate 10, the mutual transmission and conversion of forces between them will cause the shell 2 to generate periodic vibrations in the vertical direction. This cycle repeats, allowing the shell 2 to generate multi-directional vibrations multiple times. This multi-directional vibration allows the crushed stone to be turned over and collided multiple times in a short period of time, accelerating the speed at which small particles of crushed stone pass through the screen. During the vibration process, the crushed stone is constantly rearranged and layered. Regardless of the amount of feed, it can ensure that the crushed stone has enough opportunities to be screened to a certain extent. Even if a large amount of crushed stone enters the shell, the multi-directional vibration can still quickly disperse the crushed stone and start the screening process, resulting in relatively high efficiency.
[0026] See Figure 1 An L-shaped support frame 13 is fixedly installed on the top of the base 1. The servo motor 3 is located on the top of the L-shaped support frame 13. A protective cover is provided on the outside of the L-shaped support frame 13. The protective cover is fixedly installed on the top of the L-shaped support frame 13.
[0027] The L-shaped support frame 13 is fixed to the top of the base 1, providing a stable mounting foundation for the servo motor 3. Its special L-shaped structure can effectively distribute the weight of the servo motor 3 as well as the vibration and torque generated during operation, preventing the servo motor 3 from shifting or shaking due to unstable installation, thus ensuring the normal operation of the servo motor 3.
[0028] See Figure 2 The top of the shell 2 is fixedly installed with a feed hopper 17, and the outer circumference of the shell 2 is fixedly installed with a discharge pipe 8. The screening screen 14 is inclined from the feed hopper 17 toward the discharge pipe 8.
[0029] The discharge pipe 8 is fixed to the outer circumference of the shell 2 and works in conjunction with the inclined screen 14 to achieve an efficient discharge and screening process. The screen 14 is inclined from the feed hopper 17 toward the discharge pipe 8. When the crushed ore is subjected to vibration or other power in the shell 2, it will gradually move toward the discharge pipe 8 along the inclined surface of the screen 14. During the movement, small particles of ore that meet the aperture requirements of the screen 14 will pass through the screen and fall into the discharge pipe 8 for discharge, while large particles of ore will remain on the screen 14 for further crushing or recycling. This design allows the material to flow naturally under the action of gravity, reducing additional power consumption and enabling continuous screening and discharge operations, thereby improving the overall production efficiency of the crusher.
[0030] See Figure 3 An installation plate is fixedly connected to the outer circumference of the housing 2. Two elastic plates 10 are fixedly installed between the installation plate and the base 1. The two elastic plates 10 are symmetrically arranged, and the cross-section of the elastic plates 10 is arc-shaped.
[0031] The uniform force distribution and good buffering effect mean that the arc-shaped elastic plate 10 bears relatively small fatigue stress during long-term repeated stress. This helps to reduce the generation and propagation of micro-cracks inside the elastic plate 10, improve its fatigue resistance, and reduce the frequency of replacing the elastic plate 10 due to fatigue damage, thereby reducing equipment maintenance costs and downtime.
[0032] See Figure 1 A first crushing device 11 is fixedly installed at the bottom of the base 1, and a second crushing device 12 is provided on one side of the first crushing device 11. The second crushing device 12 is located below the discharge pipe 8.
[0033] Because the positions of the first crushing device 11 and the second crushing device 12 are closely related to the discharge pipe 8 of the shell 2, the separation of ores of different particle sizes at each stage during the crushing process is more accurate. Inside the shell 2, after preliminary vibration screening, ores of suitable particle size move to the discharge pipe 8, while larger particles remain inside the shell 2 for further crushing or enter the second crushing device 12. The material processed by the second crushing device 12 can also be screened again or further separated according to its characteristics. This layout is conducive to improving the overall crusher's separation effect on ores and reducing the generation of unqualified products.
[0034] See Figures 4-5 The cross-section of the first semi-cylinder 6 is set as a U-shaped block.
[0035] The first semi-cylinder 6 has a U-shaped cross-section. When in contact with the rotating rod 5, the U-shaped structure can provide a more stable contact surface. Compared with other shapes, the two side walls of the U-shape can effectively restrict the lateral sliding of the rotating rod 5, so that the interaction force between the rotating rod 5 and the first semi-cylinder 6 is transmitted more stably. For example, when the rotating rod 5 rotates and collides and slides against the first semi-cylinder 6, the U-shaped block structure can better withstand and transmit the pushing force applied by the rotating rod 5, avoiding the loss of force or irregular transmission due to unstable contact, thereby ensuring the normal operation of the entire vibration structure.
[0036] See Figures 4-5 Multiple square blocks 15 are provided on one side of both the first semi-cylinder 6 and the second semi-cylinder 7, and multiple fixing bolts 16 are threadedly connected to one side of the square blocks 15.
[0037] Based on specific work requirements, the staff has the ability to flexibly adjust the number of square blocks 15. When the number of square blocks 15 is increased sequentially, the relative spatial arrangement between the rotating rod 5 and the first semi-cylinder 6, and between the rotating rod 5 and the second semi-cylinder 7, changes due to the increase in the number of square blocks 15. The contact area between the two is significantly increased. This increase in contact area allows the thrust exerted by the rotating rod 5 on the first semi-cylinder 6 and the second semi-cylinder 7 during rotation to be greatly increased under the same operating conditions. As the thrust increases, the force received by the shell 2 also increases accordingly under the synergistic action of the elastic system composed of the return spring 9 and the elastic plate 10, which in turn causes the vibration amplitude of the shell 2 to increase significantly. In this way, by controlling the number of square blocks 15, the vibration amplitude of the shell 2 can be effectively changed to adapt to diverse working scenarios such as different types of ores, particle sizes, and processing requirements, providing a strong guarantee for the efficient crushing and precise separation of ores.
