[0002] A coal mine refers to a place rich in coal resources. Coal is a combustible organic rock formed by the remains of ancient organisms underground through long-term geological changes. During the coal mining process, transportation devices are needed to transport coal and waste rock because the materials generated during mining operations need to be moved from the working face to the ground or other treatment locations. The role of transportation devices is crucial. They improve production efficiency, reduce the need for manual handling, lower labor intensity, and ensure the smooth flow of materials within the mine.

The right side of the fixing plate is fixedly connected to the left side of the crushing box 9.

[0033] Specifically, the screening box 1 serves as the main framework of the entire device, bearing and accommodating all the crushing, screening, and transportation components. The base 19 provides a stable support foundation for the device and is also the installation point for the moving components. The first rotating rod 2 is a key component for power transmission. One end of it receives power through the first pulley 3, and the other end transmits power through the turntable 4. The first pulley 3 is connected to the second pulley 14 by a belt and receives power from the motor 15. The turntable 4 is fixed on the first rotating rod 2 and converts the rotational power into linear motion through the thin rod 5. The thin rod 5 is fixedly connected to the turntable 4 and slides inside the hollow shell 6 to achieve linear motion. The hollow shell 6 accommodates the thin rod 5 and converts the rotational power of the turntable 4 into the up-and-down motion of the ejector rod 7. The ejector rod 7 is fixedly connected to the hollow shell 6 and pushes the screen 8 up and down to prevent the screen 8 from being blocked. The screen 8 is used for screening the crushed coal mine, allowing qualified small particles to pass through, while larger particles are separated. The crushing box 9 accommodates two crushing rollers 11 for initially crushing the coal mine. Each rotating shaft 10 is fixed with a crushing roller 11 and a first gear 12 for crushing the coal mine and transmitting power. The motor 15 provides power for the entire device and transmits the power to the rotating shaft 10 through the second pulley 14 and the belt. The motor 15 provides power for the entire device and transmits the power to the rotating shaft 10 through the second pulley 14 and the belt. The first bevel gear 13 is fixed on the front rotating shaft 10 and meshes with the second bevel gear 26 to achieve vertical power transmission. The first gear 12 is fixed on the rotating shaft 10, and the two crushing rollers 11 rotate synchronously through meshing. The support plate 16 provides support for the second rotating rod 17 to ensure its stable rotation. The second rotating rod 17 receives power from the first bevel gear 13 through the second bevel gear 26 and transmits it to the fourth pulley 22 through the third pulley 18. The third pulley 18 is fixed on the second rotating rod 17 and is connected to the fourth pulley 22 by a belt to transmit power. The receiving box 24 collects the coal mine particles that are not completely crushed. The conveying pipe 25 transports the coal mine particles in the receiving box 24 to the inside of the outer shell 20. The outer shell 20 accommodates the spiral blade 23 and the rotating shaft 21 for transporting the coal mine that is not completely crushed. The rotating shaft 21 rotates inside the outer shell 20 to drive the spiral blade 23 to work. The spiral blade 23 sends the coal mine that is not completely crushed back into the crushing box 9 for secondary crushing. The fourth pulley 22 receives power from the third pulley 18 and drives the rotating shaft 21 to rotate. The limit block 34 is fixed on the inner wall of the screening box 1 to limit the movement range of the ejector rod 7 and ensure the normal operation of the screen 8. The fixing plate is fixed on the left side of the crushing box 9 to provide additional support for the second rotating rod 17.

[0034] Refer to Figure 1 and Figure 3, the moving component includes a connecting block 27. The top of the connecting block 27 is fixedly connected to the bottom of the base 19. The bottom of the connecting block 27 is fixedly connected with a double-headed electric push rod 28. The output end of the double-headed electric push rod 28 is fixedly connected with a fixing block 29. Both the front and rear sides of the fixing block 29 are rotatably connected with a second gear 30. The outer sides of the two second gears 30 are fixedly connected with a mounting frame 31. The bottom of the mounting frame 31 is fixedly connected with a universal wheel 32. Four racks 33 are fixedly connected to the bottom of the base 19. The racks 33 and the second gears 30 are meshed with each other.

[0035] Specifically, the connecting block 27 serves as a connecting bridge between the base 19 and other parts of the moving component, ensuring the structural stability and consistency. The double-headed electric push rod 28 is an electric actuator with a two-way telescopic function. It controls the movement of the fixing block 29 through telescopic actions, thereby realizing the deployment and retraction of the universal wheel 32. The fixing block 29 serves as a supporting structure for the second gear 30. Its movement is controlled by the double-headed electric push rod 28, which in turn drives the movement of the second gear 30 and the mounting frame 31. The second gear 30 meshes with the rack 33, and the lifting of the mounting frame 31 and the universal wheel 32 is realized through rotation. When the fixing block 29 moves under the action of the double-headed electric push rod 28, the second gear 30 rolls along the rack 33, driving the mounting frame 31 and the universal wheel 32 to rotate accordingly. The mounting frame 31 provides an installation position for the universal wheel 32 and is also the carrier of the second gear 30. Its movement determines the position and state of the universal wheel 32. The universal wheel 32 is a key component for realizing the movement of the device. It can freely turn, facilitating the adjustment of direction in complex terrains. When the universal wheel 32 is lowered and contacts the ground, the device can be easily moved by pushing or towing; when the universal wheel 32 is retracted, the device is fixed on the ground to ensure stability during work. The rack 33 is fixed to the bottom of the base 19 and meshes with the second gear 30, providing a fixed guiding path for the second gear 30 to move along a predetermined trajectory, thereby precisely controlling the lifting of the universal wheel 32.

[0036] Working principle: When the device needs to be used, first, the device needs to be moved to a designated location. Then, start the double-headed electric push rod 28 to push the fixing block 29 and the second gear 30 to move to both sides. Since the second gear 30 and the rack 33 are meshed with each other, the second gear 30 rotates while moving. While the second gear 30 rotates, it drives the mounting frame 31 and the universal wheel 32 to rotate downward until the universal wheel 32 contacts the ground, and the device enters the moving state. When it reaches the designated location, for the stability of the transportation work, at this time, start the double-headed electric rod 28 to pull the fixing block 29 inward to move to the middle. Through the meshing between the second gear 30 and the rack 33, it drives the second gear 30 to rotate, and then drives the mounting frame 31 and the universal wheel 32 to rotate inward into the device, so that the universal wheel 32 is retracted into the base 19. At this time, the loading work can begin.

[0037] The motor 15 drives to drive one of the rotating shafts 10 and the crushing rollers 11 to rotate. Under the action of the first gear 12, the other crushing roller 11 is driven to rotate to crush the coal mine. The crushed coal mine will fall onto the screen 8 through the discharge port at the bottom of the crushing box 9. In order to avoid clogging of the screen 8 and separate the incompletely crushed coal mine, at this time, under the action of the second pulley 14 and the belt outside the first belt 3, the rotational power of the rotating shaft 10 is transmitted to the first rotating rod 2. The first rotating rod 2 drives the disc 4 to rotate. The turntable 4 drives the thin rod 5 to slide in the hollow shell 6, converting the rotational power of the turntable 4 into the linear motion of the hollow shell 6, driving the ejector rod 7 to reciprocate up and down to push the screen 8. The completely crushed coal mine will fall from the screen holes to the bottom of the screening box 1, while the unqualified coal mine is sent to the receiving box 24 by the shaking motion of the screen 8 and conveyed to the inside of the housing 20 through the conveying pipe 25. Under the action of the rotating shaft 10, the first bevel gear 13 is driven to rotate, and then the meshing second bevel gear 26 is driven to rotate. Immediately afterwards, the second rotating rod 17 and the third pulley 18 are driven to rotate. Under the action of the belt, the fourth pulley 22 is driven to rotate, and at the same time the rotating shaft 21 and the spiral blade 23 are driven to rotate, sending the incompletely crushed coal mine back into the crushing box 9, reducing the overall volume of the coal mine, thereby increasing the carrying capacity of the coal blocks and improving the work efficiency.
