Description

Technical Field

[0002] In the mining field, the crushing device is a key equipment used to crush the original ore from larger block materials into smaller particles for subsequent extraction, processing or transportation. The mining crushing device plays a vital role in the mining and mineral processing process. The ore usually exists in its original form, and its particle size and hardness vary depending on the type of ore. Before subsequent processing, the original ore must be crushed into particles of appropriate size to increase its surface area for dissolution, leaching, flotation or other physical and chemical treatment processes. Then the crushing device used in mining usually includes different types of crushers such as jaw crusher, impact crusher, cone crusher, etc.; There are still the following defects in specific use: 1. In a jaw crusher, if the raw materials are directly dumped into the crushing chamber without effective control, excessive raw materials may enter the crushing chamber, exceeding the processing capacity of the equipment, causing equipment overload, and increasing the risk of equipment wear and damage. Secondly, direct dumping of raw materials may cause uneven distribution of raw materials in the crushing chamber. Some areas may be overloaded with raw materials, while other areas are relatively empty, affecting the crushing efficiency and particle uniformity. Excessive accumulation of raw materials in the crushing chamber may cause blockage of the crushing chamber, affecting the crushing efficiency and stable operation of the equipment, and may even cause equipment damage or accidents.

[0003] 2. In addition, the dust generated in the crushing chamber contains fine particulate matter. When these dusts flow into the environment, they will cause air pollution. Long-term exposure to a dust-polluted environment may cause harm to human health, especially to the respiratory system.

[0029] Please refer to Figure 7-Figure 8 As shown, as a preferred embodiment, a smoothing vibration mechanism 4 is used to evenly distribute the raw materials over the entire width of the crushing chamber 14 .

[0030] Please refer to Figure 7As shown, as a preferred embodiment, the smoothing vibration mechanism 4 includes a cam 41 which is fixedly connected to the outer wall of the rotating disk 23 on the side away from the driving shaft 22, and two cams 41 are symmetrically arranged with respect to the central axis of the rotating disk 23. The two cams 41 are rotatably connected to the axis of the outer wall of the side away from the rotating disk 23 with connecting rods 42, and the outer walls of the ends of the two connecting rods 42 away from the cams 41 are rotatably connected to the rotating rods 43, and the outer walls of the ends of the two rotating rods 43 away from the connecting rods 42 are rotatably connected to the long buckles 44, and the two long buckles 44 are away from the rotating rods 43. The inner walls at one end are rotatably connected with a long rod 45, the outer walls of the two cams 41 are clamped with an open slider 46, and the two long buckles 44 are rotatably connected with a support block 47 at the axis of the outer wall on one side close to the open slider 46. The outer walls of the two open sliders 46 at one end away from the cam 41 are provided with a square plate 48, and the ends of the two open sliders 46 away from the square plate 48 are fixedly connected with a slide rail 49, and the interiors of the two slide rails 49 are slidably connected with a toothed plate 410, and a shielding plate 411 is provided above the two toothed plates 410.

[0031] Please refer to Figure 7 As shown, as a preferred embodiment, one end of the two support blocks 47 away from the long buckle 44 is fixedly connected to the outer wall of one side of the fixed plate 21 close to the turntable 23, and one end of the two open sliders 46 close to the square plate 48 is slidably connected to the inside of the square plate 48.

When the long buckle 44 deflects to the lower right, it will push the long rod 45 to move downward, and then the downward movement of the long rod 45 will push the toothed plate 410 to slide inside the slide rail 49. In addition, the toothed plate 410 is respectively in conflict with the inner surfaces of the first baffle 28 and the second baffle 29.

By smoothing the vibration mechanism 4, the raw materials can be more evenly distributed before entering the crushing chamber 14, avoiding the situation where large blocks of materials are piled up or the raw materials are concentrated at the feed port, thereby improving the uniformity and stability of the crushing process.

[0033] The following are the complete usage steps and working principles of the above embodiment.

[0034] The device is mainly used for: Figure 1 The jaw crusher 1 is a commonly used crushing equipment, which is mainly used to crush materials of various hardness and strength. First, the raw material enters the crushing chamber 14 of the jaw crusher 1 through the feed port on the upper surface of the support plate 11. Figure 2 The raw material is crushed by pressure between the passive jaw plate 12 and the static jaw plate 13. There are a pair of fixed static jaw plates 13 and a pair of movable jaw plates 14 in the crushing chamber 14 of the jaw crusher 1. The raw material is clamped between the dynamic jaw plate 12 and the static jaw plate 13, and is crushed into smaller particles or fragments as the dynamic jaw plate 12 moves. The crushed material is then discharged from the crushing chamber 14 through the discharge port at the bottom of the support plate 11.

[0035] The intermittent opening and closing mechanism 2 is used to control the feeding speed and amount of the raw materials so as to match the processing capacity of the crushing chamber 14 when it is used.

[0036] like Figure 3 As shown, since the output end of the drive shaft 22 away from the fixed plate 21 is a bidirectional motor, the operator can drive the drive shaft 22 to rotate clockwise and counterclockwise by starting the bidirectional motor. Figure 4 As shown, the end of the driving shaft 22 close to the fixed plate 21 passes through and is fixedly connected with a turntable 23. Therefore, when the driving shaft 22 rotates counterclockwise once, it will drive the turntable 23 to rotate synchronously, and then the rotating handle 24 connected to the axis of the turntable 23 away from the driving shaft 22 will first deflect counterclockwise to the left. Secondly, a crank 25 is rotatably connected to the outer wall of the end away from the axis of the rotating handle 24, and the inner wall of the end of the crank 25 away from the rotating handle 24 is also rotatably connected to the first connecting rod 26. In this way, when the rotating handle 24 deflects counterclockwise to the left, it will also drive the crank 25 to deflect clockwise to the right. Then, the clockwise deflection of the crank 25 to the right will pull the first connecting rod 26 to deflect clockwise to the lower right. In addition, the inner wall of the end of the first connecting rod 26 away from the crank 25 is also rotatably connected to the second connecting rod 27. In this way, when the first connecting rod 26 deflects clockwise to the lower right, it will also pull the second connecting rod 27 to deflect counterclockwise to the lower left. Figure 3 As shown, the outer wall of the first connecting rod 26 away from the crank 25 is rotatably connected to the second baffle 29, and the outer wall of the end of the second connecting rod 27 away from the first connecting rod 26 is rotatably connected to the first baffle 28, so that when the first connecting rod 26 deflects clockwise to the lower right, it will drive the second baffle 29 to deflect clockwise to the lower right to be in a vertical state. Similarly, when the second connecting rod 27 deflects counterclockwise to the lower left, it will drive the first baffle 28 to deflect counterclockwise to the lower left to be vertical. Figure 5As shown, the second baffle 29 and the first baffle 28 are also rotatably connected to the outer walls of the two wedge blocks 210 on one side away from the first connecting rod 26. In summary, the feed speed and amount of the raw materials in the crushing chamber 14 are controlled by the opposite deflection of the first baffle 28 and the second baffle 29.

[0037] Summary 1: Compared with the prior art which directly dumps the raw materials into the crushing chamber 14, the present mechanism realizes that when the first connecting rod 26 deflects clockwise to the lower right, it will drive the second baffle 29 to deflect clockwise to the lower right to be in a vertical state. Similarly, when the second connecting rod 27 deflects counterclockwise to the lower left, it will drive the first baffle 28 to deflect counterclockwise to the lower left to be in a vertical state. The intermittent opening and closing mechanism 2 can control the feeding speed and amount of the material to match it with the processing capacity of the jaw crusher 1, which helps to prevent excessive material from entering the crushing chamber 14 and reduce equipment damage and downtime caused by overload. Secondly, by controlling the feeding amount, it is ensured that the material fed each time is evenly distributed in the crushing chamber 14, which can improve the crushing efficiency and output, avoid excessive or insufficient material from accumulating in the crushing chamber 14, and maintain the jaw crusher. 1 is in a stable operating state, and the intermittent opening and closing mechanism 2 can be opened and closed as needed when the material enters the crushing chamber 14, avoiding energy waste caused by continuous material transportation, which helps to save energy costs and improve the energy utilization efficiency of the equipment. In addition, by controlling the feed amount and feed speed, the wear of the movable jaw plate 12 and the static jaw plate 13 and other parts in the crushing chamber 14 can be reduced. Excessive material entering the crushing chamber 14 may cause the movable jaw plate 12 and the static jaw plate 13 to be subjected to additional impact and wear, and the intermittent opening and closing mechanism 2 can effectively reduce the occurrence of this situation. Finally, controlling the feed amount and speed helps to improve the safety of the equipment. Excessive material entering the crushing chamber 14 may cause the equipment to be blocked or overloaded, increasing the risk of accidents, and the intermittent opening and closing mechanism 2 can reduce this risk and improve the safety of operators and equipment.

[0038] The suction mechanism 3 is used to absorb dust and particles generated in the crushing chamber 14 to prevent them from being discharged into the environment through the crushing chamber outlet.

[0039] like Figure 6As shown, after the operator connects a bidirectional motor to the shaft output end of the driving shaft 22, the bidirectional motor drives the driving shaft 22 to rotate, and the outer wall of the driving shaft 22 close to the fixed plate 21 is also connected to the belt 31 for transmission. Therefore, the rotation of the driving shaft 22 will also drive the belt 31 to rotate, and then the pulley 32 fixedly connected to the axis of the outer wall of the end of the belt 31 away from the fixed plate 21 will also rotate. At the same time, the disk 33 rotatably connected to the axis of the outer wall of the end of the pulley 32 away from the belt 31 will also rotate. Furthermore, an eccentric obstacle column 34 is eccentrically fixedly connected to the outer wall of the disk 33 away from the pulley 32, and the opening slot body 35 is slidably connected to the inside of the opening slot body 35. Therefore, when the disk 33 rotates, the eccentric obstacle column 34 will be driven to move together, so that the eccentric obstacle column 34 will move up and down inside the opening slot body 35. Furthermore, the opening slot body 35 The outer walls on both sides are fixedly connected with piston rods 36, and the two piston rods 36 are slidably connected to the inside of the two piston cylinders 37 respectively. Therefore, when the rotation of the disc 33 drives the eccentric obstacle column 34 to move up and down inside the open groove body 35, it will also push the two open groove bodies 35 to reciprocate inside the two piston rods 36. In addition, the two piston cylinders 37 are provided with circular openings at one end away from the open groove body 35. Therefore, the dust particles generated in the crushing chamber 14 can be sucked in through the circular openings through the reciprocating movement of the two piston rods 36 in the two piston cylinders 37. In addition, the upper end outer walls of the two piston cylinders 37 are also connected with an air intake pipe 39, and the end of the air intake pipe 39 away from the piston cylinder 37 is also fixedly connected to the collection box 310. Therefore, after the dust particles are sucked in through the circular opening, they will flow into the collection box 310 through the air intake pipe 39 to complete collection, which is convenient for subsequent processing.

[0040] Summary 2: Compared with the prior art, which lacks the dust generated in the crushing process of the crushing chamber 14 flowing into the environment, the present mechanism realizes that the dust particles generated in the crushing chamber 14 can be sucked in through the circular opening by the reciprocating movement of the two piston rods 36 inside the two piston cylinders 37. After the dust particles are sucked in through the circular opening, they will flow into the collection box 310 through the air inlet pipe 39 to complete the collection, which is convenient for subsequent treatment. A large amount of dust will be generated in the crushing process. Placing the suction mechanism 3 in the crushing chamber 14 can timely suck in and collect the dust to prevent it from spreading to the surrounding environment and reduce air pollution. Secondly, a large amount of dust will be generated in the crushing process. Placing the suction mechanism 3 in the crushing chamber 14 can timely suck in and collect the dust Dust can be prevented from spreading to the surrounding environment, reducing air pollution. The dust generated during the crushing process may be deposited inside the machine, causing wear and failure of the equipment. By sucking and collecting the dust in the crushing chamber 14, the erosion of the equipment by the dust can be reduced and the service life of the equipment can be extended. Furthermore, by reducing the generation and diffusion of dust, the suction mechanism 3 helps to improve the working efficiency of the jaw crusher 1, reduce energy waste, and save energy costs. Finally, the dust and particles generated during the crushing process may block the channel or filter inside the crushing chamber 14, affecting the feeding and discharging of raw materials. The dust and particles in the crushing chamber 14 are cleaned in time by the suction mechanism 3, which can reduce the possibility of blockage and ensure the normal operation of the equipment.

[0041] The smoothing vibration mechanism 4 is used to evenly distribute the raw materials over the entire width of the crushing chamber 14. like Figure 8 As shown, when the drive shaft 22 rotates counterclockwise once to drive the turntable 23 to rotate synchronously, since a cam 41 is eccentrically fixedly connected to the outer wall of the turntable 23 away from the drive shaft 22, and an opening slider 46 is also clamped on the outer wall of the cam 41, the rotation of the turntable 23 causes the cam 41 to roll on the inner wall of the opening slider 46, and pushes the opening slider 46 to slide obliquely back and forth inside the square plate 48. In addition, a connecting rod 46 is rotatably connected to the axis of the cam 41 away from the opening slider 46. The inner wall of the end of the connecting rod 42 away from the cam 41 is rotatably connected to the rotating rod 43, and the rotating rod 43 is also rotatably connected to the long buckle 44 away from the connecting rod 42. When the cam 41 rotates, the connecting rod 42 is pulled to deflect counterclockwise to the upper left. When the connecting rod 42 deflects counterclockwise to the upper left, the rotating rod 43 is pulled to deflect clockwise to the upper right. Therefore, when the rotating rod 43 deflects clockwise to the upper right, the long buckle 44 is pushed to deflect counterclockwise to the lower right. Figure 7The end of the long buckle 44 shown in the figure which is away from the rotating rod 43 is also rotatably connected to the long rod 45, and the end of the long rod 45 which is away from the long buckle 44 is rotatably connected to the toothed plate 410, and the toothed plate 410 is slidably connected to the inside of the slide rail 49, so when the long buckle 44 deflects to the lower right, it will push the long rod 45 to move downward, and then the downward movement of the long rod 45 will push the toothed plate 410 to slide inside the slide rail 49. In addition, the toothed plate 410 respectively contacts the inner surfaces of the first baffle 28 and the second baffle 29, so the sliding of the toothed plate 410 will cause the raw materials remaining on the inner surfaces of the first baffle 28 and the second baffle 29 to be scraped, and the vibration generated by the oblique sliding of the opening slider 46 on the base 38 can also better realize the effect of smoothing the raw materials by the toothed plate 410.

[0042] Summary 3: Compared with the prior art, in which large blocks of materials or raw materials are easily concentrated at the feed port of the jaw crusher 1, the present mechanism realizes that when the long buckle 44 deflects to the lower right, it will push the long rod 45 to move downward, and then the downward movement of the long rod 45 will push the toothed plate 410 to slide inside the slide rail 49. In addition, the toothed plate 410 is in conflict with the inner surfaces of the first baffle 28 and the second baffle 29 respectively. Therefore, the sliding of the toothed plate 410 will cause the materials remaining on the inner surfaces of the first baffle 28 and the second baffle 29 to be scraped, and the vibration generated by the oblique sliding of the opening slider 46 on the base 38 can also better achieve the effect of smoothing the raw materials of the toothed plate 410. Through the smoothing vibration mechanism 4, the raw materials can be more evenly distributed before entering the crushing chamber 14, avoiding the situation in which large blocks of materials or raw materials are concentrated at the feed port. , thereby improving the uniformity and stability of the crushing process. In addition, the smoothing vibration mechanism 4 can make the raw material present a more uniform material layer thickness when entering the crushing chamber 14, reducing the influence of the material layer thickness difference on the crushing effect, and improving the uniformity and stability of the discharge. In addition, the smoothing vibration mechanism 4 can evenly distribute the raw material at the feed port, which can reduce the blockage of the raw material when entering the crushing chamber 14, improve the working efficiency and stability of the equipment, and reduce the downtime and maintenance time of the equipment. In addition, the raw material is processed by the smoothing vibration mechanism 4 before entering the crushing chamber 14, which can make it easier for the passive jaw plate 12 to crush it, thereby improving the crushing efficiency and output. Finally, the smoothing vibration mechanism 4 can evenly distribute the raw material at the feed port, which can reduce the energy consumption of the jaw crusher 1 during operation, thereby reducing energy consumption and cost.
