Description

Technical Field

[0001] The invention relates to a crusher, in particular to an ore crusher with screening and crushing functions. Background Art

[0002] In the current industrial production environment, crushers play a vital role, especially when processing hard materials such as ore. However, when stones of different specifications mixed with mud and sand are put into the crusher for crushing, it often causes a series of problems.

[0003] First, this mixed material input method can easily cause the crusher to get clogged. Imagine that when stones of different sizes and fine sand enter the crushing chamber of the crusher together, the larger stones may not be able to enter the crushing area smoothly due to mutual squeezing and collision, while the fine sand may quickly fill the gaps in the crushing chamber, causing a significant drop in crushing efficiency, or even completely blocking the operation of the crusher. This will not only affect production efficiency, but may also damage the equipment and increase maintenance costs.

[0004] Secondly, even if the crushing process can be carried out barely, the crushed stones often need to be screened again due to the inconsistency of material specifications. This is because the crushed stones may still contain large stones that have not been completely crushed and too many fine particles. In order to meet production requirements, these stones must be further screened to remove the parts that do not meet the specifications. This not only increases the complexity and cost of the production process, but may also affect the quality and performance of the product.

[0005] Therefore, in order to avoid these problems, we need to improve the crusher. Summary of the invention

[0006] In order to overcome the shortcomings of the existing crusher that when crushing ore, the crusher is easily blocked due to the different specifications of stones, and the crushed stones need to be screened twice after crushing, which reduces the production efficiency, the present invention provides an ore crusher with screening and crushing functions.

The brush is located at the corresponding position of the filter screen, and the pushing block is located at the corresponding position of the first screen hole, the second screen hole and the discharge through hole.

[0012] As a preferred technical solution of the present invention, the end of the pushing block is set to be conical. The pushing block can extend into the through hole under the action of the return spring to achieve the effect of pushing the ore. The end of the pushing block is set to be conical to provide an inclined surface, so that the pushing block can be extruded from the side wall of the through hole after extending into the through hole.

[0013] As a preferred technical solution of the present invention, it further includes a stirring roller. The stirring roller is rotatably connected to the screening cylinder and they are coaxial. The stirring roller can not only disturb the ore in the screening cylinder to improve the passing efficiency of the ore in the screening cylinder, but also guide the ore to push the ore of each size to move to the corresponding through hole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.

[0029] Embodiment: An ore crusher with screening and re-crushing functions, as Figures 1-4As shown in the figure, it includes a base 1, a sieve cylinder 3, a power unit 4, a crushing tank 5 and a jaw crusher unit. The crushing tank 5 is fixedly connected to the base 1. The sieve cylinder 3 is rotatably connected inside the crushing tank 5. The sieve cylinder 3 is successively provided with a sieve mesh, a first sieve hole 302, a second sieve hole 303 and a discharge through hole 304. The aperture of the first sieve hole 302 is smaller than that of the second sieve hole 303. The power unit 4 supplies energy to the sieve cylinder 3. The power unit 4 is composed of a servo motor and a pulley group. The servo motor is fixed on the base 1 through a bracket. The output shaft of the servo motor drives the sieve cylinder 3 to rotate through the pulley group. During this period, a speed reduction gear set is configured, specifically a large gear and a small gear that mesh with each other. The pulley group drives the small gear, and the large gear is arranged at the right end of the sieve cylinder 3. The large gear is driven by the small gear to increase the torque and save power. The sieve cylinder 3 is inclined and a feed inlet is provided at the higher end. The feed pipe 2 is fixedly connected to the base 1, and the feed pipe 2 can be docked with the feed inlet of the sieve cylinder 3. In this embodiment, there are three jaw crushers with increasing sizes from right to left. The sizes of the feed ports are 1060*700, 1400*1200 and 1500*1300 respectively, and the corresponding maximum feed sizes are 560mm, 960mm and 1040mm respectively. The feed size matches the diameter of the through hole provided outside the sieve cylinder 3, that is, the aperture of the first sieve hole 302 is 550mm, the aperture of the second sieve hole 303 is 900mm, and the aperture of the discharge through hole 304 is much larger than 1040mm. Therefore, the ore mixed with sediment is guided into the sieve cylinder 3 through the feed pipe 2. The sieve cylinder 3 rotates continuously through the power unit 4, and the sieve cylinder 3 will also perform multi-stage screening on the ore. Among them, fine particles such as sediment are discharged through the sieve mesh. The ore with a diameter less than 550mm will fall into the first sieve hole 302 and enter the rightmost jaw crusher for crushing. The ore with a diameter between 550mm and 900mm will fall into the middle jaw crusher for crushing through the second sieve hole 303, while the larger ore will fall into the left jaw crusher through the discharge through hole 304. The discharge ports of each jaw crusher can be separately collected to perform subsequent processing on ores of different particle sizes according to different requirements.

[0030] As Figure 4 shown, the crushing tank 5 is provided with a sediment chute 501. The sediment chute 501 is located at the corresponding position of the sieve mesh. After the ore enters the sieve cylinder 3, the fine sediment mixed in the ore will be discharged through the sieve mesh and then fall into the sediment chute 501 for unified collection and processing by the staff.

[0031] As Figure 5 and Figure 6 shown, it also includes a cleaning bracket 7. The cleaning bracket 7 is fixedly connected to the side of the crushing tank 5. The cleaning bracket 7 can be in frictional contact with the sieve cylinder 3. During the rotation of the sieve cylinder 3, ores with different shapes may get stuck in the through holes, which is likely to cause blockage of the sieve cylinder 3. Therefore, the cleaning bracket 7 is provided to clean the through holes of the sieve cylinder 3 immediately.

[0032] As Figure 6As shown in the figure, the cleaning bracket 7 is provided with a brush 8 and a pushing block 9. The pushing blocks 9 are arranged at equal intervals and are slidably connected to the cleaning bracket 7. A return spring 901 is connected between the pushing block 9 and the cleaning bracket 7. The brush 8 is located at the corresponding position of the filter screen 301. The brush 8 can continuously brush the screen to prevent small stones from blocking the filter screen 301. The brush 8 is made of a high-hardness plastic material, so that the brush 8 not only has elasticity, but also has the hardness to push small stones, effectively preventing the filter screen 301 from being blocked. The pushing block 9 is located at the corresponding positions of the first sieve hole 302, the second sieve hole 303 and the discharge through hole 304. The end of the pushing block 9 is set to be conical. The pushing block 9 can extend into the through hole under the action of the return spring 901 to achieve the effect of pushing the ore. The end of the pushing block 9 is set to be conical to provide an inclined surface, so that the pushing block 9 can be extruded by the side wall of the through hole after extending into the through hole, reducing the influence of the pushing block 9 on the rotating sieve cylinder 3.

[0033] As Figure 7 shown in the figure, it further includes a stirring roller 10. The stirring roller 10 is rotatably connected to the sieve cylinder 3 and they are coaxial. The stirring roller 10 is provided with radial stirring rods. The stirring roller 10 can not only disturb the ore in the sieve cylinder 3, improve the passing efficiency of the ore in the sieve cylinder 3, but also guide the ore and push ores of various sizes to move to the corresponding through holes.

[0034] As Figure 7 and Figure 8 shown in the figure, it further includes a fixed bracket 11, a transmission gear 12, a gear ring 13 and a driven gear 14. The fixed bracket 11 is fixedly connected to the side of the crushing groove 5. The fixed bracket 11 is rotatably connected with a transmission gear 12. A gear ring 13 is arranged at the end of the sieve cylinder 3. A driven gear 14 is connected to the end of the stirring roller 10. The gear ring 13 meshes with the transmission gear 12, and the transmission gear 12 meshes with the driven gear 14. The sieve cylinder 3 is continuously rotated by the power unit 4. The gear ring 13 is located on the left side of the sieve cylinder 3. The gear ring 13 will drive the transmission gear 12 to rotate, and then the transmission gear 12 will drive the driven gear 14 to rotate, thereby driving the stirring roller 10 to rotate. Since the stirring roller 10 and the sieve cylinder 3 rotate in the left direction, the pushing and guiding effects of the stirring roller 10 can be further improved.

[0035] Working principle of this embodiment: The ore is introduced into the feeding pipe 2. Since the feeding pipe 2 is provided with baffles, it effectively prevents the ore from overflowing. As an extension, the feeding pipe 2 can be docked with an external ore conveying device, such as a conveyor belt, etc., to achieve the effect of continuous feeding. The ore enters the screening cylinder 3 from the feeding pipe 2, and then the screening cylinder 3 is driven to rotate by the power unit 4. Since the screening cylinder 3 is arranged in a 15-degree inclined shape with the left end lower and the right end higher, at the same time, the rotating screening cylinder 3 drives the driven gear 14 to rotate through the transmission gear 12, and then drives the stirring roller 10 to rotate. The stirring roller 10 can push and guide the ore. Therefore, when the screening cylinder 3 rotates, it can drive the ore to move from right to left. During this period, ores of different sizes will pass through different through holes, and fine sediment will be discharged through the filter screen 301 to the sediment chute 501 for unified cleaning. The ores are respectively discharged from the first sieve hole 302, the second sieve hole 303 and the discharge through hole 304. The first sieve hole 302, the second sieve hole 303 and the discharge through hole 304 are respectively configured with jaw crushers with increasing feeding particle sizes, and are crushed by the jaw crushers for grading to improve the processing efficiency of the ore.

[0036] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
