Description

Technical Field

[0001] The present invention relates to the field of ore processing, and more particularly to an ore processing technology. Background Art

[0002] Crushing is a critical process in ore processing. Jaw crushers, due to their stable performance, are the primary tool for coarse crushing. They crush ore through the relative motion of the static and moving jaw plates, with the spacing between the two plates directly determining the resulting particle size. Existing jaw crushers have significant drawbacks in adjusting the spacing: Traditional equipment requires manual removal and modification of spacers, a cumbersome and time-consuming process, and cannot quickly and accurately adapt to varying ore sizes or process requirements. Some hydraulic adjustment devices only move the moving jaw plate in one direction, which can easily lead to deviations in parallelism between the two plates, resulting in uneven crushing particle size. Furthermore, they cannot dynamically adjust to the feed in real time, resulting in poor adaptability. Summary of the Invention

[0005] Edge plates are fixed on opposite surfaces of the two static jaw plates, and each edge plate is provided with a plurality of ridges from top to bottom.

[0006] A connecting plate is fixed to the lower side of each strip rod, and the two connecting plates are respectively fixed to the outer sides of the two baffles, and the static jaw plate and the movable jaw plate are both located between the two baffles.

[0030] like Figure 5-6 As shown;

[0031] Since the ore processing device includes a static jaw plate 101, a connecting frame 110 is fixed to the left side of the static jaw plate 101, and strip rods 103 are fixed to the front and rear ends of the connecting frame 110. The right parts of the two strip rods 103 are provided with transverse holes 109. Fixed shafts 105 are fixed to the front and rear sides of the upper part of the movable jaw plate 108. The two fixed shafts 105 are respectively inserted into the two transverse holes 109. A retaining ring 106 is fixed to each fixed shaft 105, and the two retaining rings 106 are respectively fitted with the two strip rods 103. The movable jaw plate 108 can move laterally along the transverse hole 109 through the fixed shaft 105 thereon, and then adjust the distance between the static jaw plate 101 and the movable jaw plate 108 according to the size of the ore. Then the movable jaw plate 108 can rotate with the fixed shaft 105 as the axis, driving the movable jaw plate 108 to continuously rotate and open and close to crush the ore. The retaining ring 106 can prevent the fixed shaft 105 from moving back and forth relative to the strip rod 103, thereby preventing the movable jaw plate 108 from moving back and forth relative to the two strip rods 103, making the movable jaw plate 108 more stable. By adjusting the distance between the static jaw plate 101 and the movable jaw plate 108, it can adapt to the crushing operation of ores of different sizes, and adjusting the distance between the static jaw plate 101 and the movable jaw plate 108 is simple and convenient.

[0032] like Figure 5-6 As shown;

[0033] Because ridges 102 are fixed to the opposing surfaces of the two static jaw plates 101, and each ridge plate 102 is provided with a plurality of ridges from top to bottom, when the movable jaw plate 108 approaches the static jaw plate 101 to squeeze the ore, the ridges on the ridge plates 102 can increase the contact stress with the ore, making the ore more easily split and crushed. Compared to smooth jaw plate surfaces, the ridges can improve the crushing efficiency of the ore, especially for ores with higher hardness, which can be crushed to the desired particle size more quickly. At the same time, the provision of the ridges can also reduce the slippage of the ore during the crushing process, making the crushing process more stable. The structural design of the ridges improves the crushing ability of the device for ores of different hardness.

[0034] like Figure 5-8 As shown;

[0035] Since a connecting plate 104 is fixed to the lower side of each of the strip bars 103, and the two connecting plates 104 are respectively fixed to the outer sides of the two baffles 201, the static jaw plate 101 and the movable jaw plate 108 are both located between the two baffles 201. The connecting plates 104 connect and fix the strip bars 103 to the baffles 201, so that the baffles 201 can limit the left and right sides of the static jaw plate 101 and the movable jaw plate 108, preventing the ore from falling from both sides during ore crushing. At the same time, the baffles 201 can also prevent the static jaw plate 101 and the movable jaw plate 108 from deviating to the sides when subjected to force, ensuring that the two are always in the correct relative position, thereby improving the stability of crushing. In addition, the baffles 201 can also reduce the splashing of ore debris during the crushing process, improving operational safety. The provision of the baffles 201 makes the structure of the device more stable and the crushing operation more reliable.

[0036] like Figure 5-8 As shown;

[0037] Because the static jaw plate 101 and the rib plate 102 are each provided with a plurality of through-holes, a plurality of insert plates 111 are slidably connected to the through-holes. A left frame 202 is fixed between the left ends of the two baffle plates 201. A hydraulic cylinder is fixed to the left frame 202, and a connecting rod 203 is fixed to the end of the hydraulic cylinder. The left sides of the plurality of insert plates 111 are each fixed to the connecting rod 203. The hydraulic cylinder on the left frame 202 drives the plurality of insert plates 111 to slide within the through-holes via the connecting rod 203. The length of the insert plates 111 extending beyond the surfaces of the static jaw plate 101 and the rib plate 102 can be adjusted. When finer crushing is required, extending the insert plates 111 longer can provide additional ore segmentation and refine the crushing particle size. When processing larger ores, the extended length of the insert plates 111 can be shortened to avoid excessive obstruction of ore crushing. The hydraulic cylinder's drive makes the insert plates 111 easy to adjust, allowing the crushing effect to be flexibly adjusted according to the characteristics of the ore. The adjustable design of the insert plates 111 enhances the adaptability of the device to different crushing requirements.

[0038] like Figure 5-8 As shown;

[0039] Since the right side of the movable jaw plate 108 is provided with a bar hole 107, a right frame 206 is fixed between the right ends of the two baffles 201. A hydraulic cylinder is fixed to the right frame 206. A sliding pin 205 is fixed to the movable end of the hydraulic cylinder. The sliding pin 205 is inserted into the bar hole 107. When the hydraulic cylinder on the right frame 206 is extended or retracted, the sliding pin 205 moves in the bar hole 107, thereby driving the movable jaw plate 108 to rotate, thereby crushing the ore.

[0040] like Figure 5-8 As shown;

[0041] Because rails 208 are fixed to the outer sides of the two baffles 201, the lower portions of the two shaft frames 207 are respectively connected to the two rails 208 for transverse sliding. Both shaft frames 207 are driven to slide by hydraulic cylinders, and the two fixed shafts 105 are respectively rotatably connected to the upper portions of the two shaft frames 207. Driven by the hydraulic cylinders, the shaft frames 207 can slide transversely along the rails 208, driving the fixed shaft 105 and the movable jaw plate 108 to move as a whole, thereby adjusting the spacing between the static jaw plate 101 and the movable jaw plate 108 to meet the crushing requirements of ores of different sizes. The hydraulic cylinder drive ensures smooth and precise adjustment. The coordination between the shaft frames 207 and the rails 208 makes spacing adjustment more flexible and the device more adaptable.

[0042] like Figure 7-10 As shown;

[0043] A bracket 302 is fixed to the top of the stationary jaw plate 101, and a movable plate 303 is slidably connected to the right side of the bracket 302. Round rods 304 are fixed to the front and rear sides of the movable plate 303. Slots 204 are provided on the tops of the two shaft brackets 207, and the two round rods 304 are respectively inserted into the two slots 204. When the shaft brackets 207 slide along the tracks 208, the slots 204 drive the round rods 304 to move, causing the movable plate 303 to slide on the gate-shaped edge 301, thereby adjusting the size of the opening in the area enclosed by the gate-shaped edge 301 and the movable plate 303, so that the opening serves as the feed port. The size of the feed port can automatically change with the change in the spacing between the stationary jaw plate 101 and the movable jaw plate 108, so that the poured ore can be accurately poured between the stationary jaw plate 101 and the movable jaw plate 108, thereby improving the uniformity of crushing and the stability of the equipment.

[0044] like Figure 1-12 As shown;

[0045] Since support legs 404 are fixed to the left and right ends of the lower side of each baffle 201, a crossbeam 405 is vertically slidably connected between the two support legs 404 on the front side and between the two support legs 404 on the rear side. The crossbeam 405 is driven up and down by a hydraulic cylinder, and the front and rear ends of the rotating shaft 406 are respectively rotatably connected to the middle part of the two crossbeams 405. A motor 403 is fixed on the crossbeam 405 on the front side, and the output shaft of the motor 403 is connected to the front part of the rotating shaft 406. A plurality of insertion strips 407 are arranged on the rotating shaft 406 from front to back, and the plurality of insertion strips 407 are all arranged below the gap between the static jaw plate 101 and the movable jaw plate 108. When a blockage occurs between the static jaw plate 101 and the movable jaw plate 108, the hydraulic cylinder drives the crossbeam 405 to rise, allowing the insertion strip 407 to extend into the gap. The motor 403 drives the rotating shaft 406 and the insertion strip 407 to rotate, stirring and clearing the blocked ore, ensuring that the crushed ore is discharged smoothly and avoiding the continuity of the crushing operation due to blockage. The lifting and lowering of the crossbeam 405 and the rotation of the insertion strip 407 cooperate to realize the automatic clearing function, reduce the trouble of manual cleaning, and ensure the efficient operation of the device.

[0046] like Figure 11-12 As shown;

[0047] Because the two right-side support legs 404 are each provided with a fixed seat 408, the front and rear edges of the inclined plate 401 are slidably connected to the two fixed seats 408. The front and rear ends of the upper side of the inclined plate 401 are provided with a ridge 402. The inclined plate 401 is driven to slide by a hydraulic cylinder. When the multiple insertion bars 407 are not in use, the multiple insertion bars 407 are rotated to the left and then lowered. At this time, the inclined plate 401 is driven to slide to the upper left along the two fixed seats 408, so that the left end of the inclined plate 401 is located below the gap between the lower ends of the static jaw plate 101 and the movable jaw plate 108. After the crushed ore falls between the static jaw plate 101 and the movable jaw plate 108, it lands on the inclined plate 401 and slides down the inclined plate. The ridge 402 prevents the ore from falling from both sides of the inclined plate.

[0048] An ore processing process comprises the following steps:

[0049] S1: Adjust the distance between the static jaw plate 101 and the movable jaw plate 108 according to the size of the ore to be crushed;

[0050] S2: Pour the ore between the static jaw plate 101 and the movable jaw plate 108, and drive the movable jaw plate 108 to continuously rotate and open and close to crush the ore;

[0051] S3: The ore falling from between the static jaw plate 101 and the movable jaw plate 108 falls on the inclined plate 401 and slides down;

[0052] S4: When the lower ends of the static jaw plate 101 and the movable jaw plate 108 are blocked, a plurality of inserting strips 407 are used to clear the gap between the static jaw plate 101 and the movable jaw plate 108 .
