[0027] Example 1, such as Figure 1 As shown, a green and environmentally friendly coal mining crushing device includes a crushing box 1, a motor 3 fixedly connected to the crushing box 1, a fixed crushing roller 2 fixedly connected to the output shaft of the motor 3, and the fixed crushing roller 2 rotatably connected to the crushing box 1.

[0028] Reference Figure 1 and Figure 3The crushing box 1 is equipped with an adjustment structure 4, which mainly consists of two adjustment slots 41. The two adjustment slots 41 are respectively opened on both sides of the crushing box 1. An adjustment block 42 is slidably connected in the adjustment slot 41. A rotating shaft 43 is rotatably connected to the adjustment block 42. A moving crushing roller 6 is fixedly connected to the rotating shaft 43. When the worker puts the coal into the crushing box 1 through the upper opening of the crushing box 1, the motor 3 is started. The output shaft of the motor 3 drives the fixed crushing roller 2 to rotate. The rotating shaft 43 rotates in the opposite direction, driving the moving crushing roller 6 to rotate. This allows the fixed crushing roller 2 and the moving crushing roller 6 to work together to crush the coal. The distance between the fixed crushing roller 2 and the moving crushing roller 6 can be adjusted by sliding two adjusting blocks 42, thus making it suitable for different types of coal mines. This avoids the situation where the roller spacing cannot be adjusted, resulting in incomplete crushing for harder or larger coal pieces, while causing over-crushing for softer or smaller coal pieces, which not only wastes energy but also increases the cost of subsequent screening and processing. A first bevel gear 44 is fixedly connected to one end of the rotating shaft 43 and the fixed crushing roller 2. A second bevel gear 45 is meshed with the first bevel gear 44, and a second bevel gear 45 is fixedly connected to one of the second bevel gears 45. A sliding rod 46 is rotatably connected to an adjusting block 42. A rotating rod 47 is rotatably connected to the crushing box 1. The rotating rod 47 is fixedly connected to a second bevel gear 45. The sliding rod 46 and the rotating rod 47 are slidably connected. The output shaft of the motor 3 drives the fixed crushing roller 2 to rotate, which in turn drives a first bevel gear 44 to rotate, and in turn drives a second bevel gear 45 to rotate. This causes the rotating rod 47 and the sliding rod 46 to rotate synchronously, so the two second bevel gears 45 rotate synchronously, which in turn causes the two first bevel gears 44 to rotate synchronously in opposite directions. When adjusting block 42, slide rod 46 slides on rotating rod 47, making operation more convenient. An electric telescopic rod 48 is fixedly connected in an adjusting groove 41. One end of the electric telescopic rod 48 is fixedly connected to the adjusting block 42. The adjusting block 42 can be moved by starting the electric telescopic rod 48, making the position of the adjusting block 42 more stable. Two limit blocks 49 are fixedly connected to slide rod 46. The limit blocks 49 are slidably connected to the inner wall of rotating rod 47. The limit blocks 49 slide at the upper limit of rotating rod 47, which can prevent the slide rod 46 and rotating rod 47 from rotating and affecting the transmission effect.

[0030] The working principle is that the workers put the coal into the crushing box 1 through the upper opening of the crushing box 1, start the motor 3, the output shaft of the motor 3 drives the fixed crushing roller 2 to rotate, the reverse rotating shaft 43 drives the movable crushing roller 6 to rotate, so that the fixed crushing roller 2 and the movable crushing roller 6 can crush the coal together, the distance between the fixed crushing roller 2 and the movable crushing roller 6 can be adjusted by sliding the two adjusting blocks 42, and then it can be suitable for different types of coal, so as to avoid the situation that the roller spacing cannot be adjusted, the coal is not completely crushed, the soft or small block of coal is easily over-crushed, not only waste energy, but also increase the subsequent screening and processing cost, the output shaft of the motor 3 drives the fixed crushing roller 2 to rotate, which can drive a first bevel gear 44 to rotate, and then drive a second bevel gear 45 to rotate, so that the rotating rod 47 and the sliding rod 46 rotate synchronously, so that the two second bevel gears 45 rotate synchronously, further making the two first bevel gears 44 rotate reversely, and when the adjusting block 42 is adjusted, the sliding rod 46 slides on the rotating rod 47, so that the operation is more convenient, the electric telescopic rod 48 can be started to drive the adjusting block 42 to move, so that the position of the adjusting block 42 is more stable, the limiting block 49 is limited to slide on the rotating rod 47, which can prevent the sliding rod 46 and the rotating rod 47 from rotating, affecting the transmission effect, the guide plate 52 can guide the coal to fall between the fixed crushing roller 2 and the movable crushing roller 6, improving the crushing effect, and the angle of the guide plate 52 can be changed by rotating the rotating shaft 51 to adapt to the movable crushing roller 6 at different positions, when the position of the guide plate 52 is adjusted, the limiting rod 54 is slid to be clamped into the corresponding limiting groove 55, which can limit the guide plate 52, when the limiting rod 54 is clamped into the corresponding limiting groove 55, the spring 56 is in a stretched state, so that the rebounding force of the spring 56 acts on the limiting rod 54, making the limiting more stable, when crushing, the liquid pump 58 is started, the liquid pump 58 pumps the water source in the water collecting tank 57 to the spray pipe 59, which is sprayed through a plurality of atomizing nozzles, which can reduce dust, prevent a large amount of dust from entering the air, and cause damage to the environment.
