Description

Technical Field

[0001] This utility model belongs to the field of crushing device technology, specifically relating to an ore crusher used in mining. Background Technology

[0002] Mining is a crucial part of the mining industry, its purpose being to extract ore from underground and perform preliminary crushing. The crushing process is not only an important step in ore processing, but also plays a significant role in improving ore processing efficiency, reducing energy consumption, and lowering production costs.

[0003] Currently, the technology for using ore crushers in mining is developing rapidly, but in practical applications, there are still some technical problems that urgently need to be solved. Traditional ore crushers often suffer from problems such as unstable positioning, low feeding efficiency, and difficulty in removing crushed ore accumulation, resulting in low production efficiency, inconvenient operation, and even certain safety hazards.

[0004] During ore crushing, traditional crushing equipment often struggles to meet the crushing requirements of various ores due to differences in ore type, size, and hardness. Especially for processing large pieces of ore, traditional equipment frequently requires manual intervention for feeding and adjustments, resulting in low production efficiency. Furthermore, crushed ore often accumulates at the crusher outlet; an improperly designed discharge system can hinder timely ore removal, leading to equipment overload and shutdown, thus affecting production continuity.

[0005] Therefore, improving the automation level of ore crushers and solving problems such as unstable equipment position, difficulty in feeding, and poor discharge during the ore crushing process are technical challenges that urgently need to be addressed in the mining industry. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide an ore crusher for mining operations. By optimizing the structure and working principle of the crushing equipment, it can effectively improve the ore feeding efficiency, crushing efficiency and discharge efficiency, reduce the need for manual operation, and improve the stability and safety of production.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mining ore crusher includes a support frame, a drive motor, and a crusher. Both the drive motor and the crusher are installed inside the support frame. The drive motor drives the crusher to work via a transmission belt. The crusher also includes a feeding mechanism and a discharging mechanism. The left end of the feeding mechanism is rotatably installed on the upper right end of the crusher, and the feeding mechanism can transport ore into the crusher. The right end of the support frame is equipped with multiple hydraulic rods that drive the right end of the feeding mechanism to swing up and down.

[0009] The discharge mechanism is horizontally positioned below the discharge port of the crusher. The discharge mechanism conveys the stone to the left, and a discharge plate that cooperates with the discharge mechanism is fixed at the left end of the support frame.

[0010] Furthermore, multiple evenly distributed rollers are fixed to the lower side of the support frame, and height-adjustable fixed support legs are also fixed to the lower side of the support frame.

[0011] Furthermore, the fixed support leg includes an L-shaped fixing frame fixed to the side of the support frame. A support screw is threaded through the horizontal part of the fixing frame. A rotating handle is fixed to the upper end of the support screw, and a pad is connected to the lower end of the support screw.

[0012] Furthermore, the feeding mechanism includes a feeding frame, the left end of which is rotatably mounted on the crusher, and the right end of which is fixed with a material support plate. The upper and lower ends of the hydraulic rod are respectively hinged to the feeding frame and the support frame.

[0013] Furthermore, a feeding conveyor belt is provided on the inner side of the feeding rack, and a feeding motor that drives the feeding conveyor belt to roll is fixed on the side of the feeding rack.

[0014] Furthermore, the discharge mechanism includes a discharge frame fixed inside the support frame, a discharge conveyor belt is provided on the inner side of the discharge frame, and a discharge motor for driving the discharge conveyor belt to roll is fixed on the side of the discharge frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Firstly, in traditional ore crushing processes, the fixed and unstable position of the equipment easily leads to unstable operation of the crusher. This invention achieves stability and adaptability by introducing an adjustable support device, including rollers installed under the support frame and fixed support legs. The height-adjustable design of the fixed support legs ensures smooth operation of the crusher in different terrains or working environments, avoiding equipment tilting and instability, thereby improving the safety and reliability of crushing operations.

[0017] Secondly, existing technologies often require manual intervention in the feeding process, resulting in low feeding efficiency and affecting the continuity of crushing operations. This invention improves the feeding mechanism by using a hydraulic system to drive the feeding frame for precise lifting and lowering, in conjunction with a feeding motor driving the feeding conveyor belt, enabling the automatic and stable transport of large pieces of ore into the crusher. This design not only improves feeding efficiency and reduces manual intervention but also effectively avoids jamming when feeding large pieces of ore, thereby improving production efficiency and automation levels.

[0018] Third, traditional crushers suffer from ore accumulation and poor discharge during the discharge process, especially when crushing large quantities of ore, which can easily lead to equipment blockage and production stoppage. This invention addresses these issues with its discharge mechanism, which features a transverse discharge conveyor belt and a high-power discharge motor. This ensures timely ore delivery and effectively prevents accumulation as crushed ore is rapidly discharged. The efficient design of the discharge system guarantees continuous equipment operation, avoids equipment overload caused by poor discharge, and thus improves overall production efficiency.

[0019] Finally, the overall structure and component configuration of the crusher have been optimized, and materials with high wear resistance and compressive strength have been selected to ensure the stability and durability of the equipment during long-term operation. This efficient and reliable design reduces the frequency of equipment maintenance and operating costs, while improving the continuity and stability of ore crushing operations.

[0031] like Figure 3As shown, the fixed support leg 21 includes an L-shaped fixing frame 212 fixed to the side of the support frame 2. A support screw 213 is threaded through the horizontal part of the fixing frame 212. A rotating handle 211 is fixed to the upper end of the support screw 213, and a pad 214 is connected to the lower end of the support screw 213. The support screw 213 is made of high-strength alloy steel and its surface is heat-treated to ensure its wear resistance and compressive strength. The rotating handle 211 is made of aluminum alloy, which has a light weight and is easy for operators to adjust. The pad 214 is made of wear-resistant steel plate with a thickness of 15mm, which can effectively support the crusher and ensure that the equipment does not shift during operation.

[0032] like Figure 4 As shown, the feeding mechanism 6 includes a feeding frame 62, the left end of which is rotatably mounted on the crusher 5, and the right end of the feeding frame 62 is fixed with a support plate 64. The upper and lower ends of the hydraulic rod 7 are hinged to the feeding frame 62 and the support frame 2, respectively. The feeding frame 62 is made of high-strength steel and can withstand a large material weight. The support plate 64 has a size of 1000mm × 800mm and is coated with a wear-resistant coating to improve its service life. The hydraulic rod 7 is a YZJ-80 model hydraulic rod with a maximum working pressure of 10MPa, which can ensure the precise lifting and lowering of the feeding frame and avoid tilting or failure to lift and lower normally.

[0033] A feeding conveyor belt 63 is installed on the inner side of the feeding rack 62, and a feeding motor 61 that drives the feeding conveyor belt 63 to rotate is fixed on the side of the feeding rack 62. The feeding conveyor belt 63 is made of PVC material and is 800mm wide, capable of carrying a large amount of ore and transporting it smoothly to the crusher; the feeding motor 61 is a 7.5kW motor model YB2-180L-4, ensuring the continuous and stable operation of the feeding conveyor belt and providing sufficient power to handle the feeding of large pieces of ore.

[0034] like Figure 5 As shown, the discharge mechanism 3 includes a discharge frame 31 fixed within the support frame 2. A discharge conveyor belt 32 is installed on the inner side of the discharge frame 31, and a discharge motor 33, which drives the discharge conveyor belt 32, is fixed to the side of the discharge frame 31. The discharge frame 31 is also made of Q235 steel plate to ensure the durability and wear resistance of the discharge system.

The discharge motor 33 has a rated power of 5.5kW and is model YB2-180M-4, ensuring stable operation under different loads and effectively preventing system failures due to insufficient power.

[0035] Example 2: Height Adjustment and Stability Improvement of the Support System

[0036] In this embodiment, to address the issues of unstable equipment positioning and unreliable operation in existing ore crushers, a support system with height adjustment is employed. Multiple evenly distributed rollers 22, made of alloy steel and 250mm in diameter, are installed beneath the support frame to withstand the overall weight of the equipment, ensuring stable operation during movement. Simultaneously, fixed support legs 21 with adjustable height (300mm) are also provided beneath the support frame to adapt to different terrains and environments. The support legs are made of cast iron, possessing high compressive strength and effectively preventing tilting or instability of the equipment.

[0037] This support system effectively solves the crusher tilting problem caused by equipment instability in existing technologies. By adjusting the height of the support legs, the stability of the crusher in different working environments can be ensured, thereby improving the equipment's efficiency and safety.

[0038] Comparative Cases:

[0039] Traditional ore crushers typically employ fixed structures or simple adjustment methods for their support systems, lacking designs adaptable to different terrains. Crusheres using such support systems are prone to tilting or instability during operation, affecting crushing efficiency and production productivity. The support system in this embodiment, however, solves the stability problems of traditional equipment by designing adjustable support legs and rollers, effectively improving the equipment's working efficiency and safety.

[0040] Example 3: Optimization and Efficiency Improvement of Automatic Feeding System

[0041] This embodiment optimizes the design to address the efficiency issue of the ore crusher's feeding system. The feeding mechanism 6 includes a feeding frame 62, made of high-strength steel to ensure its load-bearing capacity and stability. The left end of the feeding frame is rotatably connected to the crusher 5, and the right end is fixed with a support plate 64, made of Q235 steel plate with a thickness of 10mm and coated with a wear-resistant coating to improve its service life. The two ends of the hydraulic rod 7 are hinged to the feeding frame 62 and the support frame 2, respectively. It uses a YZJ-80 hydraulic system with a maximum working pressure of 10MPa, enabling precise up-and-down adjustment and automatic completion of the feeding process.

[0042] During operation, the hydraulic system drives the lifting of the feeding rack 62 to smoothly transport the ore to the feed inlet of the crusher, solving the problem of manual intervention in the traditional ore feeding process and greatly improving the level of automation and feeding efficiency.

[0043] Comparative Cases:

[0044] Traditional ore crusher feeding systems typically rely on manual operation or simple mechanical conveying devices, which are inefficient and prone to ore jamming, leading to poor feeding. In contrast, this embodiment combines a hydraulic drive system with an automatic feeding conveyor belt, which can efficiently and accurately feed large pieces of ore into the crusher, avoiding manual intervention and jamming, and significantly improving production efficiency and automation level.

[0045] Example 4: Design and Application of High-Efficiency Discharge System

[0046] In this embodiment, a high-efficiency discharge system is designed to address the problem of poor material discharge after ore crushing. The discharge mechanism 3 includes a discharge frame 31 made of Q235 steel plate with a thickness of 12mm, which is highly wear-resistant. Inside the discharge frame, there is an 800mm wide discharge conveyor belt 32 made of high-temperature resistant and wear-resistant rubber material, which can bear large pieces of ore and effectively prevent blockage. The discharge motor 33 is a 5.5kW YB2-180M-4 type motor, which can ensure the continuous and stable operation of the discharge conveyor belt.

[0047] The design of the discharge system enables the crushed ore to be quickly discharged from the bottom of the crusher and transported to the discharge area, avoiding the problems of ore accumulation or equipment overload, and ensuring the high efficiency and stability of the equipment in long-term operation.

[0048] Comparative Cases:

[0049] Traditional ore crusher discharge systems often result in ore accumulation and poor conveying, especially during high-load operations, where discharge difficulties become more pronounced, easily leading to equipment overload and shutdown. In contrast, the high-efficiency discharge system in this embodiment, through optimized configuration of the conveyor belt and discharge motor, can quickly and effectively remove crushed ore, ensuring smooth ore processing and greatly improving production efficiency.

[0050] Example 5: Overall Structure Optimization and Material Selection of Crusher

[0051] This embodiment optimizes the overall structure and material selection of the crusher. Crusher 5 adopts a PE-900×1200 jaw crusher, and the crushing chamber structure has been adjusted in design to adapt to the crushing requirements of larger ore particles. The main components of the crusher are made of high-strength alloy steel, and the surface has been heat-treated, giving it extremely high wear resistance and compressive strength, effectively coping with the high pressure and wear generated during ore crushing.

[0052] In addition, the drive motor 4 is a 15kW YB2-315M-4 type motor, equipped with a high-efficiency transmission belt system to ensure full power output and stable operation of the equipment. The optimized design of the crusher 5 enables the equipment to operate stably for a long time, reducing the frequency of failures and lowering maintenance costs.

[0053] Comparative Cases:

[0054] Traditional ore crushers, due to limitations in material selection and design, often experience severe wear and frequent malfunctions after prolonged operation, impacting production efficiency and equipment lifespan. In contrast, this embodiment, through optimized crusher structural design and the use of wear-resistant alloy steel, significantly improves the crusher's stability and durability, reduces maintenance costs, and exhibits higher efficiency and a longer service life when processing large-particle ore.

[0055] The working principle of this utility model is as follows: when crushing ore, the entire device is moved to the crushing outlet, and then the support screw 213 is rotated by the handle 211 to make the pad 214 descend and support the ground, thereby completing the position fixation of the crushing device.

[0056] Then, larger pieces of ore are placed on the support plate 64. At this time, the hydraulic rod 7 drives the feeding rack 62 to rise until it is in a horizontal state. Then, the feeding motor 61 drives the feeding conveyor belt 63 to roll and send the large pieces of ore into the inside of the crusher 5 for crushing, so as to better complete the automatic feeding when crushing larger pieces of ore.

[0057] The crushed ore from the crusher 5 is discharged from its lower outlet and falls onto the discharge conveyor belt 32. At this time, the discharge motor 33 drives the discharge conveyor belt 32 to transport the ore to the right and guide it through the discharge plate 1 for discharge, thereby completing the rapid discharge and guidance of the crushed ore and preventing the accumulation of crushed ore.

[0058] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
