[0018] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.
[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] See Figure 1-4 In this embodiment of the utility model, a special conveyor for replacing coal mill liners includes a support platform 1. First support frames 2 are provided at both ends of the bottom of the support platform 1, and support components are provided at the front and rear ends of the first support frames 2. A first connecting recess 6 is provided on the side wall of the support platform 1, and the first connecting recess 6 is connected to a discharge plate 8 via a first rotating shaft 7. A reset component for resetting the discharge plate 8 is installed on the first support frame 2. An opening 18 is provided inside the support platform 1, and several sets of connecting grooves 19 are equally spaced on the inner walls at both ends of the opening 18. A conveying roller 20 is rotatably mounted on the connecting groove 19. A rotation drive component for driving the conveying roller 20 to rotate is installed on the support platform 1. A cleaning component for cleaning the conveying roller 20 is provided at the bottom of the support platform 1.
[0022] This invention places the coal mill liner on the conveying roller 20 and drives the conveying roller 20 to rotate via a rotation drive assembly. The conveying roller 20 moves the conveyed coal mill liner to the discharge plate 8. The discharge plate 8 is squeezed by the coal mill liner and rotates at an angle relative to the first rotating shaft 7. This causes the discharge plate 8 to tilt under pressure, which facilitates the discharge of the coal mill liner and makes it easier to replace the coal mill liner.
[0023] See Figure 3 In one embodiment of this utility model, the support component includes a mounting bolt 3 threadedly connected to the first support frame 2. The top of the mounting bolt 3 is provided with a rotating disk 4, and the bottom of the mounting bolt 3 is connected to the support base 5. By manually rotating the rotating disk 4, the rotating disk 4 drives the mounting bolt 3 to rotate and move up and down, so as to adjust the position of the support base 5 and facilitate the leveling of the special conveyor.
[0024] See Figure 3In one embodiment of this utility model, the reset assembly includes a support frame 11 fixedly connected to the first support frame 2. A guide rod 12 is fixedly mounted on the support frame 11, and a limit block 13 is provided at the end of the guide rod 12. A sliding seat 14 is provided on the guide rod 12, and a connecting spring 15 is sleeved on the guide rod 12 located on one side of the sliding seat 14. A second connecting notch 16 is opened at the top of the sliding seat 14. The second connecting notch 16 is connected to the transmission rod 28 through a third rotating shaft 17. The end of the transmission rod 28 is connected to the mounting frame 9 through a second rotating shaft 10. The top of the mounting frame 9 is connected to the discharge plate 8. Driven by the gravity of the coal mill liner, the discharge plate 8 rotates around the first rotating shaft 7, adjusting its angle to ensure that the discharge plate 8 tilts. The discharge plate 8 simultaneously drives the mounting frame 9 to rotate. The mounting frame 9 drives the sliding seat 14 to move under the guidance of the guide rod 12 via the transmission rod 28. The connecting spring 15 is compressed to generate elastic force, thereby stabilizing the tilted discharge plate 8 and facilitating the discharge of coal mill liners. After the coal mill liner has finished discharging, the elastic force can drive the discharge plate 8 to reset, thus facilitating the dedicated conveying of coal mill liners.
[0025] See Figure 2 In one embodiment of this utility model, a plurality of anti-slip sleeves 21 are provided at equal intervals on the conveying roller 20. The anti-slip sleeves 21 can increase the friction between the conveying roller 20 and the coal mill liner, thereby facilitating the replacement and conveying of the coal mill liner.
[0026] See Figure 2 In one embodiment of this utility model, the rotation drive assembly includes a pair of pulleys 22 fixedly connected to the conveying roller 20 located outside the support platform 1. The pulleys 22 are interconnected by a transmission belt 23. A fixed frame 24 is provided on the outer wall of the support platform 1, and a conveying motor 25 is installed on the fixed frame 24. The conveying motor 25 is connected to the conveying roller 20. When the conveying motor 25 works, it drives the conveying roller 20 to rotate. The conveying roller 20 drives each conveying roller 20 to rotate synchronously through the pulleys 22 and the transmission belt 23, thereby facilitating the special conveying of coal mill liners.
[0027] See Figure 3 In one embodiment of this utility model, the cleaning component includes a second support frame 26 fixedly connected to the bottom of the support platform 1. A cleaning brush 27 is provided on the top of the second support frame 26. The top of the cleaning brush 27 is in contact with the conveying roller 20. During the rotation of the conveying roller 20, the cleaning brush 27 performs rotation cleaning on the rotating conveying roller 20, thereby facilitating the cleaning of the conveying roller 20 and ensuring the conveying process of the conveying roller 20.
[0028] Working Principle: This utility model operates via a conveyor motor 25, which drives the conveyor rollers 20 to rotate. The conveyor rollers 20 drive the pulleys 22 to rotate, and the pulleys 22 drive the conveyor rollers 20 to rotate synchronously via a transmission belt 23. By placing the coal mill liner on the rotating conveyor rollers 20, the anti-slip sleeves 21 on the conveyor rollers 20 drive the coal mill liner to move and transport. When the coal mill liner moves to the discharge plate 8, the gravity of the coal mill liner compresses the discharge plate 8. The discharge plate 8 rotates at an angle with the first rotating shaft 7 as the center, causing the discharge plate 8 to tilt. The discharge plate 8 synchronously drives the mounting frame 9 to rotate. The mounting frame 9 drives the sliding seat 14 to move via a transmission rod 28. The movement of the sliding seat 14 compresses the connecting spring 15 to generate elastic force, thus providing stable support for the tilted discharge plate 8, facilitating the discharge of the coal mill liner and making it easy to replace the coal mill liner.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
