Technical Field

[0001] This utility model relates to the field of ore processing technology, and in particular to an ore crushing device. Background Technology

[0002] Roller crushers are key equipment in ore processing, suitable for medium and low hardness ores (such as coal, limestone, gypsum, clay, iron ore, etc.). Their core function is to crush ore through the squeezing and shearing action of two or more rollers. They can independently complete medium or fine crushing operations, or they can be combined with jaw crushers, cone crushers, etc. to form a complete production line. At the same time, with their compact structure and stable operation, they can be adapted to different sites such as underground mines, building material plants, and mineral processing plants, making them one of the important pieces of equipment in ore processing that balances efficiency and product quality.

[0003] During operation, materials are crushed by the impact, compression, and shearing action of the toothed rollers in a roller crusher. However, in existing technologies, material blockage is a difficult problem to avoid in mining equipment production. For example, when the ore feed is uneven, unstable material conveying occurs, leading to material accumulation at the feed inlet and causing blockage. Once blockage occurs, it not only hinders the normal operation of the crusher but also significantly reduces production efficiency. Utility Model Content

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The ore crushing device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0017] like Figures 1-6 As shown, an embodiment of the present invention provides an ore crushing device, comprising a crushing chamber 11, a feed hopper 14, two feed plates 15, a crushing mechanism 2, and a vibrating feeder 5. The feed hopper 14 is located at the top of the crushing chamber 11; two feed plates 15 are symmetrically arranged inside the feed hopper 14. It should be noted that the feed hopper 14 and the crushing chamber 11 are fixed and connected by welding to ensure normal material feeding; The two sides of the feed hopper 14 adopt a hollow structure, which provides working space for the vibrating feeder 5; the size of the feed plate 15 matches the size of the feed hopper 14, and the two feed plates 15 are rotatably connected to the inner wall of the feed hopper 14 through pins. Furthermore, the two feed plates 15 are fitted against the inner wall of the feed hopper 14, and the two sides of the feed hopper 14 are sealed to ensure that the material will not spill out from the two sides of the feed hopper 14 during the vibrating feeding process.

[0018] The vibrating feeder 5 includes two sets of linkage mechanisms 3, a drive motor 41, and a drive shaft 43, wherein, Two sets of linkage mechanisms 3 are symmetrically arranged outside the feed hopper 14, and the linkage end of each set of linkage mechanisms 3 is connected to two feed plates 15; the drive motor 41 is located on the top of the crushing chamber 11, and the output shaft of the drive motor 41 is connected to the drive shaft 43; the drive shaft 43 is rotatably located on the top of the crushing chamber 11 and drives the two linkage mechanisms 3 to move synchronously. It should be noted that the drive shaft 43 is mounted on the top of the crushing chamber 11 through at least two bearing seats, which can ensure the stable rotation of the drive shaft 43 and reduce the problem of unstable operation of the linkage mechanism 3 caused by the shaking of the drive shaft 43. Specifically, both the drive shaft 43 and the output shaft of the drive motor 41 are equipped with pulleys, and the two are connected by a drive belt, so that the drive motor 41 can effectively transmit power to the drive shaft 43. The two ends of the drive shaft 43 are output ends, and both output ends are equipped with pulleys. At the same time, the drive shaft 38 in the linkage mechanism 3 is equipped with pulleys. The two pulleys are connected by a transmission belt, so that the power is effectively transmitted to the linkage mechanism 3 through the transmission belt. The drive motor 41 is a high-power and high-torque motor to drive the drive shaft 43 to drive the linkage mechanism 3 to work normally, ensuring that the feed plate 15 can reciprocate according to the set frequency and amplitude to realize vibration feeding.

[0019] In one embodiment of this utility model, such as Figure 5 As shown, the linkage mechanism 3 includes a first pivot shaft 32, two connecting rods 33, a first crank 35, a third pivot shaft 36, and a drive shaft 38, wherein, A drive shaft 38 is mounted on the feed hopper 14, and a second crank 37 is mounted at the end of the drive shaft 38; a first crank 35 is mounted on the second crank 37 via a third pivot shaft 36; a second pivot shaft 34 is mounted on the first crank 35; adjacent ends of two connecting rods 33 are connected to the second pivot shaft 34 and the third pivot shaft 36 respectively; two drive seats 31 are mounted on the far ends of the two connecting rods 33 via two first pivot shafts 32. It should be noted that the drive shaft 38 is rotatably connected to the inside of the feed hopper 14 via a bearing, and one end extends to the outside of the feed hopper 14, which is fixedly connected to the second crank 37. The first crank 35 is fixedly connected to the second crank 37 via the third pivot shaft 36, and the second pivot shaft 34 is fixedly connected to the first crank 35. The third pivot shaft 36 and the second pivot shaft 34 are symmetrically arranged with the drive shaft 38 as the center, thereby enabling synchronous driving of the two connecting rods 33. Furthermore, the adjacent ends of the two connecting rods 33 are rotatably connected to the second pivot shaft 34 and the third pivot shaft 36 respectively through bearings, and the other end of the connecting rod 33 is rotatably connected to the first pivot shaft 32 through a bearing to adapt to the angle changes during the reciprocating swing process; Among them, the two first pivot shafts 32 pass through the drive seat 31 and are fixed. The drive seat 31 is fastened to the feed plate 15 by bolts to ensure the stability of power transmission. Therefore, when the drive shaft 38 rotates, the first crank 35 and the second crank 37 both rotate around the axis of the drive shaft 38. The first crank 35 drives the connecting rod 33 through the second pivot shaft 34, while the second crank 37 drives another connecting rod 33 through the third pivot shaft 36. The two connecting rods 33 drive the drive seat 31 through the first pivot shaft 32, and then drive the feed plate 15. The two feed plates 15 reciprocate synchronously along the pins at their top, thereby realizing the action of vibrating feeding.

[0020] In one embodiment of this utility model, such as Figure 4 As shown, the two drive seats 31 are symmetrically arranged on the far sides of the two feed plates 15; It should be noted that the thickness of the drive seat 31 is greater than the maximum linear displacement of the feed plate 15 during the swing process. Therefore, when the feed plate 15 is vibrating to feed, the first pivot shaft 32 will not interfere with the position of the feed hopper 14, thus ensuring the stability of the overall structure.

[0021] In one embodiment of this utility model, such as Figure 2 As shown, the crushing mechanism 2 is located inside the crushing chamber 11. The crushing mechanism 2 includes two drive motors 21 and two crushing rollers 22, wherein... Two crushing rollers 22 are symmetrically arranged inside the crushing chamber 11; two drive motors 21 are symmetrically arranged outside the crushing chamber 11, and the output shaft of the drive motors 21 is connected to the crushing rollers 22.

[0022] It is understandable that the crushing roller 22 is set inside the crushing chamber 11 and located below the discharge port of the feed hopper 14. The two crushing rollers 22 are parallel and rotate relative to each other, and are used to crush the material falling from the feed hopper 14. The drive motor 21 is located on the outside side of the crushing chamber 11. The output shafts of the two drive motors 21 are connected to the rotating shafts of the two crushing rollers 22 through couplings to provide power for the rotation of the crushing rollers 22. It should be noted that the crushing roller 22 is made of high chromium alloy and has staggered diamond-shaped crushing teeth on its surface to achieve effective crushing of the ore. In one embodiment of this utility model, such as Figure 2 As shown, the bottom of the crushing chamber 11 is provided with a feeding hopper 12 connected to it. The feeding hopper 12 adopts a conical structure design with a larger top and a smaller bottom, which can effectively reduce the phenomenon of material jamming during the falling process of ore and ensure that the crushed ore can be discharged smoothly. The feeding hopper 12 is fixedly connected to the crushing chamber 11 by welding, which ensures the reliability of the feeding hopper 12 during long-term use.

[0023] In one embodiment of this utility model, such as Figure 1 As shown, the crushing chamber 11 is equipped with a frame 13 on the outside. The frame 13 is welded from high-strength alloy steel and has an overall frame structure. This design can effectively disperse the vibration and impact force generated during the operation of the device.

[0024] In summary, the ore crushing device of this utility model embodiment drives the transmission shaft to rotate via a transmission motor. The transmission shaft transmits power to two sets of linkage mechanisms. The drive shaft in the linkage mechanism rotates on the feed hopper, thereby driving the second crank to rotate. The second crank drives the first crank to swing through the third pivot shaft. The third pivot shaft and the second pivot shaft drive the connecting rod to move respectively. The two connecting rods drive the drive seat to move through the first pivot shaft, thereby driving the two feed plates to swing back and forth, realizing the vibration feeding of ore. After the ore material enters the crushing chamber, it is crushed by the crushing mechanism and discharged through the discharge hopper. Compared with the prior art, this utility model, by setting up a vibrating feeder, can achieve uniform feeding of ore, stable material conveying, effectively avoid material blockage, and improve production efficiency.
