[0002] Mining crushers are mechanical devices used in mining to break large pieces of ore into smaller particles. They mainly achieve primary or medium-fine crushing of ore through methods such as compression, impact, and shearing. Their core function is to provide raw materials of suitable particle size for subsequent mineral processing and transportation. They are characterized by high strength, wear resistance, and automated control, and are widely used in metal mines, coal mines, and building material mines.

[0003] During operation, the mining crusher is fed by a conveyor belt. The amount of material conveyed by the conveyor belt is not constant and will fluctuate. The mining crusher is prone to operating in a semi-cavity state. Semi-cavity operation can lead to fluctuations in particle shape and product yield, and cannot ensure operation under optimal load, which will also have a certain impact on work efficiency.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-5 As shown, this utility model provides a technical solution: a high-efficiency mining crusher, comprising: Abutment 1; High-efficiency crushing mechanism 2 is set on the top of the base 1 and is used to improve the efficiency of crushing ore. Dust suppression mechanism 3 is installed on base 1 and high-efficiency crushing mechanism 2. Dust suppression mechanism 3 is used to reduce the amount of dust flying during ore crushing. The high-efficiency crushing mechanism 2 includes a weight monitoring component and a discharge control component. The weight monitoring component includes a crushing box 21, with a crushing roller 211 rotatably connected between the two sides of the inner wall of the crushing box 21. A drive motor 212 is fixedly installed on the right side of the crushing box 21, and the output shaft of the drive motor 212 is fixedly connected to the right end of the crushing roller 211. A support leg 213 is fixedly installed at the bottom of the crushing box 21, and the support leg 213 is fixedly installed on the top of the base 1. A weighing sensor 214 is fixedly installed in the middle of the support leg 213 to control the operation of the drive motor 212, which can drive the crushing roller 211. After the ore is added into the inner cavity of the crushing box 21 by rotating the crushing roller 211, the crushing roller 211 can crush the ore. The crushed ore is discharged from the bottom. The weight of the crushing box 21 is monitored by the weighing sensor 214. The increase compared to the initial state is the weight of the ore inside the crushing box 21. When the weight of the ore is lower than the threshold, the ore is discharged. When the weight of the ore is higher than the threshold, the ore is discharged. This allows the crushing box 21 to work in a fully loaded state, increasing work efficiency. The weighing sensor 214 is a GZY32 model.

[0017] As one implementation method in this embodiment, such as Figure 3As shown, the material discharge control assembly includes a lifting arm 22, which is fixedly installed on the top of the base 1.

[0018] As one implementation method in this embodiment, such as Figure 4 As shown, a bottom frame 25 is fixedly installed at the bottom of the storage bin 23. A hydraulic cylinder 26 is fixedly installed on the side of the bottom frame 25. A gate 28 is slidably connected to the inner wall of the bottom frame 25. A connecting block 27 is fixedly installed at the telescopic end of the hydraulic cylinder 26. The connecting block 27 is fixedly installed on the outer wall of the gate 28. Controlling the extension of the hydraulic cylinder 26 can drive the two sets of gates 28 to move away from each other, causing the inner cavity of the bottom frame 25 to be in an open state, facilitating material discharge. Controlling the retraction of the hydraulic cylinder 26 can drive the gate 28 to reset, closing the inner cavity of the bottom frame 25 and stopping material discharge. A fixed installation is also installed at the top corner of the base 1. There is a control cabinet device, and the weighing sensor 214 monitors the overall weight of the crushing box 21. The weighing sensor 214 feeds back the monitored data to the control cabinet device, which then controls the hydraulic cylinder 26 to extend and retract. It is worth noting that the weighing sensor 214, control cabinet device, and hydraulic cylinder 26 in this solution are commercially available equipment that can be purchased by those skilled in the art. The equipment has not been structurally modified in this paper. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it skillfully. Therefore, this paper will not elaborate on it further.

[0019] As one implementation method in this embodiment, such as Figure 5 As shown, the dust suppression mechanism 3 includes a screen 32 and a limiting strip 33. A water storage tank 31 is provided on the top of the base 1 near the left side. The screen 32 is fixedly installed on the inner wall of the base 1. The cavity at the bottom of the screen 32 is connected to the water storage tank 31. Through the design of the screen 32, the crushed ore can be filtered, so that the internal water flows back into the inner cavity of the water storage tank 31, reducing the waste of water resources.

[0020] As one implementation method in this embodiment, such as Figure 5 As shown, the limiting strip 33 is fixedly installed on the inner wall of the water storage tank 31. An L-shaped plate 34 is movably inserted into the outer wall of the inner side of the limiting strip 33. A filter screen 35 is fixedly installed on the inner wall of the L-shaped plate 34. Through the design of the filter screen 35, the water being pumped can be filtered a second time to ensure the smooth flow of subsequent pipelines.

[0021] As one implementation method in this embodiment, such as Figure 5As shown, the dust suppression mechanism 3 also includes a pump 36 and a strip tube 37. The pump 36 is fixedly installed on the top of the base 1. The input pipe of the pump 36 extends into the inner cavity of the water storage tank 31. The output pipe of the pump 36 is fixedly connected to the outer wall of the strip tube 37. By controlling the operation of the pump 36, water inside the water storage tank 31 can be drawn and then transported to the inside of the strip tube 37 for dust suppression.

[0022] As one implementation method in this embodiment, such as Figure 3 As shown, the strip tube 37 is fixedly installed on the top of the expansion chamber 24. An atomizing nozzle 39 is fixedly connected to the outer wall of the strip tube 37. A connecting pipe 38 is fixedly connected to the right end of the strip tube 37. Through the design of the connecting pipe 38, the inner cavities of the two strip tubes 37 are connected. When the pump 36 is running, water will enter the inner cavity of the strip tube 37 and then be output from the atomizing nozzle 39, spraying onto the surface of the ore to be processed, reducing dust and increasing environmental protection. The crushing box 21 is a box-type crusher with a screenless design, which is highly adaptable to wet materials.

[0023] Working principle: In use, a portion of the ore is first stored in the cavities of the storage bin 23 and the expansion bin 24. The drive motor 212 is controlled to work, which drives the crushing roller 211 to rotate. After the ore is added into the inner cavity of the crushing box 21, the rotating crushing roller 211 crushes the ore. The crushed ore is discharged from the bottom. During the process, the weighing sensor 214 monitors the overall weight of the crushing box 21. The increase compared to the initial state is the weight of the ore inside the crushing box 21. When the weight of the ore is lower than the threshold, the hydraulic cylinder 26 is controlled to extend to discharge the ore. When the weight of the ore is higher than the threshold, the hydraulic cylinder 26 is controlled to retract to stop discharging the ore, so that the crushing box 21 is in a fully loaded state for operation. Water is added to the inner cavity of the water storage tank 31 in advance, and the pump 36 is controlled to work. The water will enter the inner cavity of the strip pipe 37 and then be output from the atomizing nozzle 39, spraying onto the surface of the ore to be processed to achieve the function of dust suppression.
