[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-5 This utility model provides an embodiment of a metal liner conveying device, comprising a support frame 1. The support frame 1 consists of two symmetrically arranged support columns 21 and a fixed column, the fixed column being fixed only to the frame of the support frame 1. A first conveying unit 2 and a second conveying unit 3 are provided at the upper end of the support frame 1. The device is movable such that the end of the second conveying unit 3 extends into the ball mill, away from the ball mill inlet.

[0020] The first conveying unit 2 includes two symmetrically arranged first vertical plates 4 and a first horizontal connecting plate 5 fixed between the lower ends of the two first vertical plates 4. The first vertical plates 4 are rotatably connected to the supporting uprights 21. A first drive roller 6 and a second drive roller 7 are rotatably connected between the two ends of the two first vertical plates 4. The first drive roller 6 and the second drive roller 7 are externally meshed with a first conveyor belt 12. This meshing connection between the conveyor belt and the drive rollers ensures that the conveyor belt maintains a stable running state during transmission, reducing slippage. A third drive roller 8 is rotatably connected between the two first vertical plates 4 along the inner side of the first drive roller 6. The third drive roller 8 is meshed with the first conveyor belt 12. A drive motor 9 is installed at the rear end of the rear first vertical plate 4. A first bevel gear 10 is connected to the output shaft of the drive motor 9. A second bevel gear 11 is meshed with one side of the first bevel gear 10. The second bevel gear 11 is coaxially connected with the third drive roller 8. The metal liner is placed on the first conveyor belt 12, the drive motor 9 is started, and the first bevel gear 10 is driven to rotate. Through the meshing connection between the first bevel gear 10 and the second bevel gear 11, the third transmission roller 8 is driven to rotate. Then, through the meshing connection between the third transmission roller 8 and the first conveyor belt 12, and the meshing connection between the first transmission roller 6 and the second transmission roller 7 and the first conveyor belt 12, the first conveyor belt 12, the first transmission roller 6 and the second transmission roller 7 are driven to rotate, so as to realize the conveying of the metal liner placed on the first conveyor belt 12.

[0021] A first fixing block 22 is fixed to the lower end of the front and rear ends of the support column 21. A first C-shaped fixing seat 23 is fixed to the outside of the first fixing block 22. A first hydraulic drive rod 24 is rotatably connected to the first C-shaped fixing seat 23 via a shaft. A first rotating block 25 is rotatably connected to the output end of the first hydraulic drive rod 24 via a shaft. A second fixing block 26 is fixed to the outer end of the first rotating block 25. The second fixing block 26 is fixed to the outer end of the first upright plate 4. Through the extension and retraction of the first hydraulic drive rod 24, the first upright plate 4 can be pushed to rotate around the connecting shaft between the support frame 1 and the first upright plate 4 as the central axis, thereby realizing the adjustment of the angle of the first conveying unit 2.

[0022] The second conveying unit 3 includes two symmetrically arranged second vertical plates 13 and a second horizontal connecting plate 14 fixed between the lower ends of the two second vertical plates 13. The second vertical plates 13 are rotatably connected to the first vertical plate 4. A fourth transmission roller 15 is rotatably connected between the two first vertical plates 4 along the outer side of the second transmission roller 7, and the rotation center axis of the second vertical plates 13 and the first vertical plates 4 is coaxial with the intermediate axis of the fourth transmission roller 15. A fifth transmission roller 16 is rotatably connected to the other end between the two second vertical plates 13. The fourth transmission roller 15 and the fifth transmission roller 16 are externally meshed with a second conveyor belt 17.

[0023] The front and rear ends of the intermediate shaft of the second drive roller 7 are equipped with first connecting gears 18, and the front and rear ends of the intermediate shaft of the fourth drive roller 15 are equipped with second connecting gears 19. The first connecting gears 18 and the second connecting gears 19 are externally meshed with a transmission belt 20. When the first conveyor belt 12 drives the second drive roller 7 to rotate, the first connecting gears 18 at both ends of the second drive roller 7 drive the second connecting gears 19 at both ends of the fourth drive roller 15 on the second conveying unit 3 to rotate via the transmission belt 20, thereby driving the fourth drive roller 15 to rotate. Then, through the meshing connection between the fourth drive roller 15 and the fifth drive roller 16 and the second conveyor belt 17, the second conveyor belt 17 is driven to rotate, conveying the metal liner falling on its upper end until it reaches the end and falls into the ball mill. This connection method using gears and transmission belts enables long-distance power transmission.

[0024] A third fixing block 27 is fixed to the lower end of the front and rear ends of the fixed pole. A second C-shaped fixing seat 28 is fixed to the outside of the third fixing block 27. A second hydraulic drive rod 29 is rotatably connected to the second C-shaped fixing seat 28 through a shaft. A second rotating block 30 is rotatably connected to the output rod end of the second hydraulic drive rod 29 through a shaft. A fourth fixing block 31 is fixed to the outer end of the second rotating block 30. The fourth fixing block 31 is fixed to the outer end of the second upright plate 13.

[0025] After each metal liner is conveyed in, the output rod end of the second hydraulic drive rod 29 retracts, causing the second vertical plate 13 on the second conveying unit 3 to rotate around the connecting shaft between the fourth transmission roller 15 and the first vertical plate 4, so that the conveying end moves toward the ball mill inlet, and the metal liner falls toward the inlet.

[0026] After the second conveying unit 3 moves a certain distance at its end, due to the height limitation at the bottom of the ball mill casing, the output rod end of the first hydraulic drive rod 24 extends to cooperate with the retraction of the output rod end of the second hydraulic drive rod 29. The extension of the output rod end of the first hydraulic drive rod 24 pushes the first conveying unit 2 to rotate around the connecting shaft between the support frame 1 and the first vertical plate 4. Simultaneously, the retraction of the output rod end of the second hydraulic drive rod 29 drives the second vertical plate 13 on the second conveying unit 3 to rotate around the connecting shaft between the fourth transmission roller 15 and the first vertical plate 4. At this time, the conveying end of the second conveying unit 3 continues to move towards the ball mill inlet, causing the metal liner's falling position to move further towards the inlet. Through this coordinated operation of the dual hydraulic drive rods, the falling position of the metal liner can be adjusted more flexibly and precisely to meet the needs of different ball mill internal spaces.

[0027] After the metal liner is conveyed, each drive structure drives its cooperating structure to reset, and then moves the device away from the ball mill in order to carry out the next conveying operation.

[0028] In the figure, the angular states of the first conveying unit 2 and the second conveying unit 3 do not represent the initial and final positions of the conveying device, but are only used to indicate that there is a rotational connection between them.

[0029] Both conveyor belts are equipped with longitudinally arranged anti-slip strips and anti-slip protrusions, which prevents the position of the metal liner relative to the conveyor belt from easily shifting due to rotation, thus ensuring the stability of the conveying process.

[0030] 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.
