Description

Technical Field

[0001] In another embodiment of this disclosure, the technology of ore crushing is involved, and more specifically, in another embodiment of this disclosure, an ore crusher for iron ore processing is involved. Background Technology

[0002] An ore crusher is a type of machinery specifically designed for iron ore processing. Its core function is to break large pieces of iron ore into smaller particles using mechanical forces (such as compression, impact, and shearing) to meet the particle size requirements of subsequent beneficiation and smelting processes. In the ore processing industry, to maximize crushing efficiency, existing ore crushers often employ an open feed inlet design. However, this design has revealed numerous drawbacks in practical applications. When the crushing wheel rotates at high speed, the ore is easily scattered under the powerful crushing force, resulting in a chaotic work site. This not only severely impacts the working environment but also poses a significant safety hazard to workers. The flying ore fragments are like invisible blades, constantly threatening the health of workers; if accidentally struck, they can cause irreversible damage or even death. Furthermore, frequent cleaning increases labor intensity and reduces overall production efficiency. Utility Model Content

[0024] like Figures 1-9 As shown, it illustrates an ore crusher for iron ore processing according to an embodiment of the present disclosure, including a crushing box 1, a diversion box 3 fixedly installed on the top of the crushing box 1, a rotating shaft 22 movably installed inside the diversion box 3, a diversion roller 26 fixedly installed on the outer surface of the rotating shaft 22, a feed inlet 4 fixedly installed on the top of the diversion box 3, and a drive wheel 19 fixedly installed at one end of the rotating shaft 22. A motor 8 is fixedly installed on the front of the crushing box 1. A drive gear 6 is fixedly installed at the output end of the motor 8. A second crushing roller 24 is movably installed inside the crushing box 1. A driven wheel 21 is fixedly installed at one end of the second crushing roller 24. A transmission belt 20 is connected between the driven wheel 21 and the drive wheel 19. A first driven gear 5 is fixedly installed at the other end of the second crushing roller 24. The first driven gear 5 and the drive gear 6 are meshed. A first crushing roller 23 is movably installed inside the crushing box 1. A second driven gear 7 is fixedly installed at one end of the first crushing roller 23. The second driven gear 7 and the drive gear 6 are meshed.

[0025] Workers pour the ore to be crushed into the distribution box 3 through the feed inlet 4, then turn on the motor 8. The motor 8 drives the drive gear 6 to rotate, which in turn drives the first driven gear 5 and the second driven gear 7 to rotate synchronously. The first driven gear 5 drives the second crushing roller 24 and the driven wheel 21 to rotate synchronously, which in turn drives the drive wheel 19 and the conveyor belt 20 to rotate. The drive wheel 19 drives the rotating shaft 22 to rotate inside the distribution box 3, which in turn drives the distribution roller 26 to rotate inside the distribution box 3. This allows the ore to be crushed to quickly enter the crushing box 1. At the same time, the drive gear 6 drives the first crushing roller 23 to rotate inside the crushing box 1. The teeth of the first crushing roller 23 mesh to crush the ore, thus completing the crushing of the ore in the crushing box 1.

[0026] During operation, the ore to be crushed is first poured into the internal space of the diversion box 3 through the feed port 4. Then, the motor 8 is started, and its power is transmitted through the transmission system to drive the drive gear 6 to rotate at high speed. Under the drive of the drive gear 6, the first driven gear 5 and the second driven gear 7 operate synchronously, and further drive the second crushing roller 24 and the driven wheel 21 to rotate in linkage. Through the transmission of the driven wheel 21, the drive wheel 19 and the conveyor belt 20 start to rotate, driving the rotating shaft 22 to rotate inside the diversion box 3. At the same time, the rotating shaft 22 drives the diversion roller 26 to operate in coordination, forming an ore conveying channel, so that the ore can quickly enter the crushing chamber of the crushing box 1. Furthermore, the drive gear 6 directly drives the first crushing roller 23 to rotate inside the crushing box 1. Utilizing the meshing action of the teeth of the first crushing roller 23, the ore is efficiently crushed, ultimately completing the ore crushing process. Compared with traditional crushers, this crusher significantly improves crushing efficiency through the coordinated design of the diverting roller 26 and the counter-rotating first crushing roller 23 and second crushing roller 24: the rotation of the diverting roller 26 achieves uniform ore distribution, avoiding accumulation, and works in conjunction with the first crushing roller 23 and second crushing roller 24 to form a continuous crushing process, reducing downtime and improving equipment utilization; the counter-rotating first crushing roller 23 and second crushing roller 24 generate bidirectional shearing force, fully crushing the ore, improving particle size uniformity, while avoiding over-crushing and reducing powder production; the diverting roller 26 disperses ore impact, extending the life of the crushing roller, and the counter-rotating force balances the load, reducing wear; in addition, this design also reduces vibration and noise, and the diverting roller 26 can flexibly adjust the ore conveying rate to adapt to different ore characteristics, ensuring stable and efficient equipment operation.

[0027] In some examples, a mounting plate 15 is movably installed inside the crushing box 1. A waste collection box 13 is fixedly installed at the bottom of the mounting plate 15. A box body 32 is fixedly installed at the top of the crushing box 1. A positioning hole 31 is opened inside the mounting plate 15. A positioning block 27 is movably installed inside the positioning hole 31. A pull rod 28 is fixedly installed at the top of the positioning block 27, and one end of the pull rod 28 passes through the inside of the box body 32. A spring 29 is fixedly installed between the box body 32 and the positioning block 27.

[0028] Before crushing the ore, the worker needs to install the waste collection box 13 at the bottom of the crushing box 1. Then, holding the pull rod 28, the worker pulls the positioning block 27 upward inside the crushing box 1. The positioning block 27 compresses the spring 29 inside the box 32, causing the positioning block 27 to pass through the inside of the crushing box 1 and enter the inside of the box 32. Now, the waste collection box 13 is installed at the bottom of the mounting plate 15. Next, holding the push rod 14, the worker pushes the mounting plate 15 into the inside of the crushing box 1. When the mounting plate 15 is completely inside the crushing box 1, the worker releases the pull rod 28. The spring 29 compresses the positioning block 27, causing the positioning block 27 to quickly enter the positioning hole 31. The positioning block 27 limits and fixes the mounting plate 15, thus completing the installation of the waste collection box 13 at the bottom of the crushing box 1.

[0029] Before crushing the ore, the waste collection box 13 is securely installed at the bottom of the crushing box 1. Then, the operator holds the pull rod 28 and uses its traction to pull the positioning block 27 upwards within the internal channel of the crushing box 1. During this process, the positioning block 27 compresses the spring 29 inside the box 32 until it smoothly passes through the internal area of ​​the crushing box 1 and enters the internal space of the box 32. Next, the waste collection box 13 is reinstalled at the bottom of the mounting plate 15, and the push rod 14 is used to push the mounting plate 15 completely into the crushing box 1. Finally, the pull rod 28 is released, and the spring 29 applies pressure to the positioning block 27, causing it to quickly enter the positioning hole 31, thereby limiting and fixing the mounting plate 15, and finally completing the installation process of the waste collection box 13 at the bottom of the crushing box 1. Compared to traditional crushers, this crusher, through the cooperation of the pull rod 28, spring 29, positioning block 27, and positioning hole 31, facilitates the installation of the waste collection box 13 at the bottom of the crushing box 1, significantly improving production efficiency and safety: reducing manual intervention, the ore falls directly into the waste collection box 13, avoiding secondary transfer and saving time and costs; enabling continuous operation, the movable or replaceable design ensures uninterrupted operation of the equipment; the enclosed structure effectively reduces dust spillage, improving the working environment and complying with environmental regulations, avoiding downtime winds; at the same time, it enhances equipment stability, the collection box acts as a support, reducing vibration and noise, and extending equipment life; in addition, the integrated design saves space, modular expansion meets different production capacity needs, facilitates maintenance and cleaning, and reduces the failure rate, making it an efficient, safe, and environmentally friendly ore processing solution.

[0030] In some examples, a filter plate 25 is movably installed inside the crushing chamber 1, and a vibration motor 30 is fixedly installed at the bottom of the filter plate 25.

[0031] When the crushed ore falls between the second crushing roller 24 and the filter plate 25 and onto the top of the filter plate 25, the vibration motor 30 is turned on. The vibration motor 30 vibrates the second crushing roller 24, causing the ore to fall quickly into the waste collection box 13, thus improving the filtration efficiency of the ore.

[0032] In some examples, a fixing seat 16 is fixedly installed on the back of the crushing box 1, a fixing block 17 is movably installed inside the fixing seat 16, and a toolbox 18 is fixedly installed on the back of the fixing block 17.

[0033] By holding the toolbox 18, the fixing block 17 is slowly placed into the fixed seat 16. The fixed seat 16 limits and fixes the fixing block 17. By adding the toolbox 18, it is convenient for the staff to take out and place maintenance tools inside the toolbox 18, which facilitates the maintenance of the instant crusher.

[0034] The waste collection box 13 has a push rod 14 fixedly installed on its side, and the push rod 14 is U-shaped.

[0035] Because the push rod 14 is U-shaped on the side of the waste collection box 13, and the U-shaped push rod 14 is ergonomic, it is easy for the staff to hold the push rod 14 and slowly push the waste collection box 13 and the mounting plate 15 into the crushing box 1, reducing the labor intensity of the staff.

[0036] In some examples, the inner diameter of the mounting base 16 is equal to the outer diameter of the mounting block 17, and the interior of the mounting base 16 has a smooth surface design.

[0037] Since the inner diameter of the fixing base 16 is equal to the outer diameter of the fixing block 17, and the interior of the fixing base 16 has a smooth surface design, it is convenient for the staff to hold the toolbox 18 and slowly put the fixing block 17 into the interior of the fixing base 16, thus ensuring the installation efficiency of the toolbox 18.

[0038] In some examples, a fixing plate 2 is fixedly installed on both sides of the crushing box 1, a support plate 10 is fixedly installed at the bottom of the fixing plate 2, and a connecting plate 11 is fixedly installed between the two support plates 10.

[0039] Since the bottom of the fixed plate 2 is fixedly installed with a support plate 10, and a connecting plate 11 is fixedly installed between the two support plates 10, the connection plate 11 and the support plate 10 cooperate to support the crushing box 1 and reduce the shaking of the crushing box 1 during use.

[0040] In some examples, a reinforcing rib 12 is fixedly installed at the angle between the support plate 10 and the connecting plate 11, and the reinforcing rib 12 is triangular in shape.

[0041] Since the reinforcing rib 12 is triangular in shape at the angle between the support plate 10 and the connecting plate 11, and the triangle has the characteristic of stability, it ensures the stability of the support plate 10 and the connecting plate 11 during use and extends the service life of the support plate 10 and the connecting plate 11.

[0042] In some examples, a support base 9 is fixedly installed on the left side of the crushing box 1, and the interior of the support base 9 has a U-shaped form.

[0043] Because the inside of the support base 9 is U-shaped on the left side of the crushing box 1, the support base 9 can provide stable support for the motor 8, reduce the shaking of the motor 8 during use, and ensure the stability of the motor 8 during use.

[0044] In some examples, the filter plate 25 has an arc shape inside the crushing chamber 1, and the internal diameter of the holes in the filter plate 25 is the same.

[0045] Because the filter plate 25 has an arc shape inside the crushing chamber 1, and the diameter of the internal holes of the filter plate 25 is the same, the arc structure allows the material to flow naturally in the crushing chamber 1, reducing the risk of material accumulation or local blockage; and the filter holes of the filter plate 25 have the same diameter, ensuring that only particles that meet the size standard can pass through quickly.

[0046] Working principle and usage process of this utility model: Workers pour the ore to be crushed into the distribution box 3 through the feed inlet 4, then turn on the motor 8. The motor 8 drives the drive gear 6 to rotate, which in turn drives the first driven gear 5 and the second driven gear 7 to rotate synchronously. The first driven gear 5 drives the second crushing roller 24 and the driven wheel 21 to rotate synchronously, which in turn drives the drive wheel 19 and the conveyor belt 20 to rotate. The drive wheel 19 drives the rotating shaft 22 to rotate inside the distribution box 3, which in turn drives the distribution roller 26 to rotate inside the distribution box 3. This allows the ore to be crushed to quickly enter the crushing box 1. At the same time, the drive gear 6 drives the first crushing roller 23 to rotate inside the crushing box 1. The teeth of the first crushing roller 23 mesh to crush the ore, thus completing the crushing of the ore in the crushing box 1.

[0047] Before crushing the ore, the worker needs to install the waste collection box 13 at the bottom of the crushing box 1. Then, holding the pull rod 28, the worker pulls the positioning block 27 upward inside the crushing box 1. The positioning block 27 compresses the spring 29 inside the box 32, causing the positioning block 27 to pass through the inside of the crushing box 1 and enter the inside of the box 32. Now, the waste collection box 13 is installed at the bottom of the mounting plate 15. Next, holding the push rod 14, the worker pushes the mounting plate 15 into the inside of the crushing box 1. When the mounting plate 15 is completely inside the crushing box 1, the worker releases the pull rod 28. The spring 29 compresses the positioning block 27, causing the positioning block 27 to quickly enter the positioning hole 31. The positioning block 27 limits and fixes the mounting plate 15, thus completing the installation of the waste collection box 13 at the bottom of the crushing box 1.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
