Description

Technical Field

[0001] This utility model relates to the field of ore crushing technology, specifically to an ore crushing device for metal smelting. Background Technology

[0002] Before metal smelting, the ore needs to be crushed to increase the reaction efficiency. Ore crushing equipment is used to crush the ore. The ore is put into the equipment, the crushing device is started, the ore is crushed, and then the crushed ore is taken out for the next step.

[0003] Patent document CN212309681U discloses an ore crushing device for metal smelting. It features a pusher plate, a processing box fixedly connected to one side of a base, and through slots on both sides of the processing box. A transmission rod is movably connected inside the through slots, and a pusher plate is fixedly connected to one side of the transmission rod. The transmission rod has a gear groove, through which a transmission gear meshes. A motor is fixedly connected to one side of the transmission gear and is also fixedly connected to the processing box. The width of the pusher plate is the same as the internal width of the processing box, but its height is greater than the height of the processing box. In operation, starting the motor drives the transmission rod via the transmission gear, causing the pusher plate to move inward, thus gathering the ore on the side of the processing box for easier crushing. However, this technical solution involves crushing the ore inside the processing box, and the crushed ore needs to be transferred again, which is cumbersome during use.

[0004] Current ore crushing processes primarily rely on jaw crushers. The ore crushed by the jaw crusher is then transported to its destination. However, when the ore entering the jaw crusher is too large, it can get stuck in the crushing chamber, causing the machine to jam. To solve this problem, a blocking unit is typically installed at the feed inlet. This unit allows ore smaller than a set diameter to pass through, while blocking larger ore from entering the feed inlet. The blocking unit effectively prevents larger ore from entering the jaw crusher. However, once larger ore is blocked, it needs to be manually removed to prevent further obstruction of the feed flow, which is cumbersome. Utility Model Content

[0005] The main objective of this invention is to provide a metal smelting ore crushing device with sorting and large-diameter ore crushing functions. This device can block large-diameter ores, which are then transferred to a crushing unit to be crushed into smaller-diameter ores. The smaller-diameter ores can then be fed back into a jaw crusher for further crushing.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: A metal smelting ore crushing device includes a jaw crusher body. A hopper is provided above the feed inlet of the jaw crusher body. The hopper is fixed to the upper end of a frame. An inverted U-shaped upper frame is fixed to the upper end of the hopper. A screening unit is provided inside the upper frame. The screening unit can block large-diameter ores. A side hopper is fixed to one side of the frame. Large-diameter ores blocked by the screening unit can enter the side hopper. Multiple support rods are fixed in the longitudinal direction inside the side hopper. A guide plate is fixed inside the side hopper above the multiple support rods. The guide plate is inclined downward at the end facing the frame. A feeding channel is formed between the end of the guide plate facing the frame and the side hopper. A crushing component is provided in the side hopper below the feeding channel. A discharge pipe is fixedly connected to the lower end of the side hopper. The crushed ore can enter the feed inlet of the jaw crusher body through the discharge pipe.

[0007] Specifically, the jaw crusher body is fixed on the frame, and a motor is fixed on the frame. The output shaft of the motor is connected to the input shaft of the jaw crusher body.

[0008] Specifically, the frame and rack are fixed to the base.

[0009] Specifically, the screening unit includes multiple baffles, with the baffles tilted downwards at the end facing the side bucket. The multiple baffles are evenly distributed in the longitudinal direction of the upper frame, with the end of the baffle away from the side bucket fixed inside the upper frame. A blocking unit is provided inside the upper frame above the multiple baffles.

[0010] Specifically, multiple support plates are fixed inside the upper frame, and the upper end of the support plates is fixedly connected to the lower end of the stop bar.

[0011] Specifically, the blocking unit includes a baffle, which is vertically arranged. The lower end of the baffle contacts the upper ends of multiple baffle rods. Vertical uprights are fixed inside the upper frames on both sides of the baffle. The baffle slides up and down between the uprights on the left and right sides. Vertical telescopic rods are fixed on the uprights, and the telescopic ends of the telescopic rods are fixedly connected to the baffle. After the baffle moves upward, the large-diameter ore blocked by the multiple baffle rods slides down into the side bucket under the guidance of the multiple baffle rods. The telescopic rod is connected to the hydraulic station through a high-pressure oil pipe and a control valve.

[0012] Specifically, the end of the guide plate facing the frame contacts the upper ends of multiple support rods.

[0013] Specifically, a fixing rod is fixed inside the frame, and the fixing rod is fixedly connected to the discharge pipe.

[0014] Specifically, the crushing assembly includes a support assembly fixed inside the side bucket. A fixing sleeve is fixed to the upper end of the support assembly. The fixing sleeve is arranged longitudinally and multiple hydraulic rods are fixed inside the fixing sleeve. A feeding trough is formed between two adjacent support rods. The multiple hydraulic rods correspond one-to-one with the multiple feeding troughs. A through hole is opened at the upper end of the fixing sleeve. The telescopic part of the hydraulic rod passes through the through hole. An upper rod is fixed on the telescopic part of the hydraulic rod. The upper rod is located inside the feeding trough. Multiple chisels are fixed to the upper end of the upper rod. The hydraulic rods are connected to the hydraulic station through high-pressure oil pipes and control valves.

[0015] Specifically, the support assembly includes a tray, which is fixed inside the side bucket. A fixing sleeve is fixed to the upper end of the tray, and the tray and the side bucket are fixedly connected by a reinforcing rib. A sealing ring is fixed inside the through hole, and the telescopic part of the hydraulic rod passes through the sealing ring. The telescopic part of the hydraulic rod is slidably and sealingly connected to the sealing ring.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By incorporating a screening unit, the equipment can automatically identify and block large-diameter ores, preventing them from directly entering the jaw crusher body. This avoids the risk of blockage, reduces downtime maintenance needs, and the guide plate design ensures that large-diameter ores are efficiently guided to the top of the feed channel for easy crushing.

[0017] 2. The crushing components installed in the side bucket can crush large-diameter ores on-site. This ensures uniform ore particle size, eliminates the need for additional equipment, optimizes the crushing process, improves overall efficiency, and enables automatic recovery of crushed ore through seamless connection with the jaw crusher via the discharge pipe.

[0018] 3. The design of sealing rings and other features effectively prevents small particles of ore from entering critical components such as hydraulic rods, avoiding wear or malfunctions caused by impurities. This not only extends the service life of the equipment but also reduces maintenance frequency and improves the reliability of the system in harsh environments.

[0019] 4. The combined design of stiffening plates, support rods, and guide plates enhances the load-bearing capacity of the side bucket and support components, ensuring stable guidance of large ore during crushing. This reduces the risk of material jamming or structural deformation, while the integrated fixing of the frame and base improves the overall shock resistance and durability of the equipment.

[0020] 5. The hydraulic rod and control valve enable automated adjustment of the crushing process, allowing operators to easily control screening, crushing, and conveying. This reduces the need for manual intervention and improves operational safety. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: Refer to Figures 1-5 As shown, a metal smelting ore crushing device includes a jaw crusher body 4, which is fixed on a frame 2. A motor 3 is fixed on the frame 2, and the output shaft of the motor 3 is connected to the input shaft of the jaw crusher body 4.

[0029] A hopper 6 is installed above the feed inlet of the jaw crusher body 4, and the hopper 6 is fixed to the upper end of the frame 5.

[0030] The frame 5 and the rack 2 are fixed on the base 1.

[0031] An inverted U-shaped upper frame 7 is fixed to the upper end of the funnel 6. A screening unit is installed inside the upper frame 7, which can block large-diameter ore. A side hopper 12 is fixed to one side of the frame 5, and large-diameter ore blocked by the screening unit can enter the side hopper 12.

[0032] The screening unit includes multiple baffles 8, with the end of each baffle 8 tilting downwards toward the side hopper 12. The baffles 8 are evenly distributed along the longitudinal direction of the upper frame 7. Multiple support plates 9 are fixed inside the upper frame 7, with the upper ends of the support plates 9 fixedly connected to the lower ends of the baffles 8. The end of each baffle 8 furthest from the side hopper 12 is fixed inside the upper frame 7.

[0033] A blocking unit is provided in the upper frame 7 above multiple stop levers 8.

[0034] The blocking unit includes a baffle 23, which is vertically arranged. The lower end of the baffle 23 contacts the upper end of multiple baffle rods 8. Vertical uprights 10 are fixed inside the upper frame 7 on both the left and right sides of the baffle 23. The baffle 23 slides up and down between the uprights 10 on the left and right sides. Vertical telescopic rods 11 are fixed on the uprights 10. The telescopic ends of the telescopic rods 11 are fixedly connected to the baffle 23.

[0035] After the baffle 23 moves upward, the large-diameter ore, which is blocked by multiple baffles 8, slides down into the side bucket 12 under the guidance of the multiple baffles 8.

[0036] The telescopic rod 11 is connected to the hydraulic station via a high-pressure oil pipe and a control valve.

[0037] Multiple support rods 14 are fixed longitudinally inside the side hopper 12. A guide plate 15 is fixed inside the side hopper 12 above the multiple support rods 14. The end of the guide plate 15 facing the frame 5 is inclined downward and contacts the upper end of the multiple support rods 14. A feeding channel is formed between the end of the guide plate 15 facing the frame 5 and the side hopper 12.

[0038] A crushing component is installed in the side bucket 12 below the feeding channel. The lower end of the side bucket 12 is fixedly connected to the discharge pipe 13. A fixing rod 24 is fixed inside the frame 5. The fixing rod 24 is fixedly connected to the discharge pipe 13. The crushed ore can enter the feed inlet of the jaw crusher body 4 through the discharge pipe 13.

[0039] The crushing assembly includes a support assembly fixed inside the side bucket 12. A fixing sleeve 18 is fixed at the upper end of the support assembly. The fixing sleeve 18 is arranged longitudinally. Multiple hydraulic rods 19 are fixed inside the fixing sleeve 18. A feeding chute is formed between two adjacent support rods 14. The multiple hydraulic rods 19 correspond one-to-one with the multiple feeding chute.

[0040] The upper end of the fixed sleeve 18 has a through hole, through which the telescopic part of the hydraulic rod 19 passes. An upper rod 20 is fixed on the telescopic part of the hydraulic rod 19. The upper rod 20 is located in the feeding trough. Multiple chisels 21 are fixed on the upper end of the upper rod 20. The hydraulic rod 19 is connected to the hydraulic station through a high-pressure oil pipe and a control valve.

[0041] During operation, the ore to be crushed is conveyed between the upper frame 7 and the baffle 23. The ore to be crushed passes through the space between two adjacent baffles 23, the funnel 6 and the feed inlet of the jaw crusher body 4 in sequence and enters the jaw crusher body 4 to be crushed.

[0042] When large-diameter ore is conveyed into the upper frame 7 and blocked by the baffle 8, the telescopic rod 11 is activated. The telescopic rod 11 drives the baffle 23 to move upward, and the large-diameter ore enters the side bucket 12 under the guidance of multiple baffles 8.

[0043] Large-diameter ore entering the side bucket 12 is guided by the guide plate 15 and gathers above the discharge channel. The large-diameter ore above the discharge channel is blocked by multiple support rods 14.

[0044] Then, the hydraulic station and control valve are turned on. The extension part of the hydraulic rod 19 drives the upper rod 20 and the chisel 21 to move up and down, thereby crushing the large-diameter ore. After being crushed, the large-diameter ore enters the jaw crusher body 4 through the feeding chute, the discharge pipe 13 and the feed port of the jaw crusher body 4 and is crushed.

[0045] Example 2: Based on Example 1, referring to... Figure 1 , Figure 3 and Figure 5 As shown, the support assembly includes a support plate 16, which is fixed inside the side bucket 12. A fixing sleeve 18 is fixed to the upper end of the support plate 16, and the support plate 16 and the side bucket 12 are fixedly connected by a stiffening plate 17.

[0046] The support plate 16 is fixed to the side wall of the side bucket 12 near the frame 5, and the stiffening plate 17 is fixedly connected to the side wall of the side bucket 12 near the frame 5 and the support plate 16. By setting the stiffening plate 17, the pressure-bearing capacity of the support plate 16 can be improved, ensuring the stability of the hydraulic rod 19 during operation.

[0047] Example 3: Based on Example 1, referring to... Figure 1 , Figure 3 and Figure 5 As shown, a sealing ring 22 is fixed inside the perforation, and the telescopic part of the hydraulic rod 19 passes through the sealing ring 22, and the telescopic part of the hydraulic rod 19 is slidably sealed to the sealing ring 22.

[0048] By setting a sealing ring 22, small particles of ore can be prevented from entering the fixed sleeve 18 through the gap between the telescopic part and the perforation of the hydraulic rod 19, thus effectively preventing dust from entering the hydraulic rod 19.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
