[0002] A coal mine refers to a mineral deposit or mining area rich in coal resources, and also to the place where coal resources are mined. Coal is a sedimentary rock-type organic mineral formed from the remains of ancient plants through complex biochemical and physicochemical processes. Its main components include elements such as carbon, hydrogen, and oxygen. It is one of the most widely used energy sources in the world, mainly used for power generation, steel manufacturing, chemical raw materials, and direct industrial and domestic fuel.
[0003] Current coal mining crushing typically involves moving crushing equipment to a designated location and then crushing it. However, current crushing equipment has limited crushing angles and poor flexibility, resulting in a small crushing range and affecting crushing accuracy. Furthermore, the crushing method is singular, relying solely on independent crushing via drill rods, leading to low crushing efficiency and inconvenience in use.
[0004] Therefore, it is necessary to design a crushing device for coal mining that can adjust the crushing height and the crushing angle in all directions to crush the mountain wall, with a large crushing range, improve the accuracy and efficiency of crushing, and enhance the flexibility and convenience of use.

The worktable 8 is connected to the upper left side of the right rotating frame 5, and the worktable 8 is slidably connected to the left rotating frame 5. Both the front and rear of the mobile vehicle 1 are equipped with components for adjusting the load. The fixing assembly for securing the mobile vehicle 1 includes pins 2, a first mounting bracket 3, and an electric push rod 4. The pins 2 are slidably connected to both the front and rear ends of the mobile vehicle 1. The lower parts of the pins 2 are tapered for easy insertion into the ground. The first mounting bracket 3 is connected to the upper sides of both the front and rear ends of the mobile vehicle 1. The pins 2 are slidably connected to the first mounting bracket 3 on the same side. The electric push rod 4 is connected to the upper and lower sides of the first mounting bracket 3. The telescopic ends of the electric push rod 4 are connected to the pins 2 on the same side. The workbench 8 is equipped with an adjusting crushing assembly for automatically adjusting the crushing angle. The adjusting crushing assembly includes a first motor 9, a second mounting bracket 10, a second motor 12, a third mounting bracket 13, and a fourth motor 14. The worktable 8 consists of two hydraulic cylinders 15, a third motor 16, and a crushing disc 17. The upper right part of the worktable 8 is connected to the first motor 9. The output shaft of the first motor 9 is connected to the second mounting bracket 10, which is rotatably connected to the worktable 8. The upper part of the second mounting bracket 10 is connected to the second motor 12. The middle part of the second mounting bracket 10 is rotatably connected to the third mounting bracket 13. The output shaft of the second motor 12 is connected to the third mounting bracket 13. The middle part of the third mounting bracket 13 is connected to the second hydraulic cylinder 15. The telescopic end of the second hydraulic cylinder 15 is connected to the third motor 16. The output shaft of the third motor 16 is connected to the crushing disc 17. The mobile vehicle 1... A dust-suppressing assembly for dust suppression is provided between the adjusting crushing components. The dust-suppressing assembly includes a water spray pipe 11, a water pump 111, a dust suction pipe 14, a vacuum cleaner 141, a water tank 18, and a filter baffle 181. The water spray pipe 11 is connected to the second mounting bracket 10, and the water pump 111 is connected to the end of the water spray pipe 11. The dust suction pipe 14 is connected to the third mounting bracket 13, and the vacuum cleaner 141 is connected to the end of the dust suction pipe 14. The water tank 18 is connected to the upper rear side of the mobile vehicle 1. The water pump 111 and the vacuum cleaner 141 are both connected to the water tank 18. The water tank 18 is made of transparent material to facilitate observation of the internal conditions. The filter baffle 181 is connected to the middle of the water tank 18.
[0024] When coal mining requires crushing, this device can be used. The mobile vehicle 1 moves the device to a designated area. Once at the designated location, the electric push rod 4 on the first mounting frame 3 is activated. The electric push rod 4 drives the pins 2 to move and insert them into the ground for fixation. The lower parts of the pins 2 are all conical to facilitate insertion into the ground, thus enabling the device to be moved and fixed, preventing displacement from affecting crushing and improving crushing stability. Then, the first hydraulic cylinder 6 is activated, causing the right rotating frame 5 to move along the guide rod 7 and the left rotating frame 5 to move along the worktable 8, causing the rotating frame 5 to rotate and the worktable 8 to rise to a position where it is closed. After reaching a suitable height, the first hydraulic cylinder 6 is closed, and then the first motor 9 and the second motor 12 are started. The first motor 9 drives the second mounting bracket 10 to rotate, and the second motor 12 drives the third mounting bracket 13 to rotate, thereby causing the crushing disc 17 to rotate. After rotating to a suitable angle, the first motor 9 and the second motor 12 are closed, and then the second hydraulic cylinder 15 is started. The second hydraulic cylinder 15 drives the third motor 16 and the crushing disc 17 to move. At the same time, the third motor 16 is started, driving the crushing disc 17 to rotate, thereby performing large-area and local crushing of the mountain wall, thus allowing for adjustment of the crushing height. The crushing angle can be adjusted in all directions to crush the mountainside, resulting in a large crushing range, improved accuracy and efficiency, and enhanced flexibility and convenience of use. Simultaneously, the vacuum cleaner 141 and water pump 111 are activated. The vacuum cleaner 141 sucks the dust generated during crushing into the suction pipe 14, which then enters the water tank 18 where it is settled by liquid. The water tank 18 is made of transparent material, allowing for easy observation of its interior. The water pump 111 causes water in the water tank 18 to flow through the filter baffle 181 and into the water spray pipe 11 for dust suppression. The water is filtered by the filter baffle 181, allowing for simultaneous dust collection and water spraying during crushing, and the filtered water can be recycled. This device improves the working environment, reduces environmental pollution, increases resource utilization, and reduces water consumption. After crushing, the third motor 16, the water pump 111, and the vacuum cleaner 141 are turned off. Then, the second hydraulic cylinder 15 operates in reverse, causing the crushing disc 17 to move and reset in the opposite direction. Next, the first hydraulic cylinder 6 operates in reverse, causing the rotating frame 5 to move and reset in the opposite direction, and the worktable 8 to descend and retract. Then, the electric push rod 4 operates in reverse, causing the pin 2 to move in the opposite direction and detach from the ground. Afterward, the second hydraulic cylinder 15, the first hydraulic cylinder 6, and the electric push rod 4 are turned off. Finally, the device is moved away by the moving vehicle 1.
