[0002] As an important material homogenization equipment, stacker-reclaimer is widely used in various industries such as mining, metallurgy, chemical industry, and building materials. However, in the process of material reclaiming, material collapse often occurs, which requires appropriate adjustment of the reclaiming speed and reclaiming angle. The reclaiming speed can be achieved by adjusting the frequency converter of the walking mechanism, but the reclaiming angle requires adjusting the inclination of the material rake. The stacker-reclaimer is a heavy equipment, and it is difficult to adjust the inclination of the material rake. Therefore, most of the time, it is not easy to prevent material collapse by simply adjusting the reclaiming speed, which results in low production efficiency. Therefore, it is necessary to provide a new material rake angle adjustment device for the reclaimer to solve the above technical problems. Utility Model Content

[0039] The working principle of the utility model is:

[0040] The lower end of the material rake 6 is positioned by the extension range of the piston rod of the hydraulic cylinder 5 .

[0041] When the lower end of the material rake 6 is positioned, the handle 17 starts to be rotated. When the handle 17 rotates, the drum 13 is driven to rotate through the mutually meshing worm wheel 14 and worm 16. When the drum 13 rotates, the wire rope 40 is driven to be released or tightened.

[0042] When the inclination angle of the material rake 6 needs to be reduced, the handle 17 is rotated clockwise, the wire rope 40 is released, and the stroke between the movable pulley block 28 and the fixed pulley block 35 becomes larger, so that the upper end of the material rake 6 continues to tilt toward the front side, and the angle between the material rake 6 and the horizontal plane becomes smaller.

[0043] When the inclination angle of the material rake 6 needs to be increased, the handle 17 is turned counterclockwise, the wire rope 40 is tightened, and the stroke between the movable pulley block 28 and the fixed pulley block 35 becomes smaller, so that the upper end of the material rake 6 is tilted toward the front side less, and the angle between the material rake 6 and the horizontal plane becomes larger.

[0044] When the handle 17 stops rotating, the meshing mechanism of the worm wheel 14 and the worm 16 has a self-locking property, which ensures that the drum 13 will not rotate automatically without rotating the handle 17. At the same time, in order to ensure absolute safety, after the angle of the material rake 6 is adjusted, the plug hole 21 on the crank handle 18 is aligned with the socket 20, and the locking pin shaft 22 is inserted into the socket 20 after passing through the plug hole 21. In this way, the handle 17 is locked and cannot drive the worm 16 to rotate, thereby ensuring that the drum 13 will not rotate automatically.

[0045] When the material rake 6 or the adjustment device needs to be repaired, the steel wire rope 40 is completely released by rotating the drum 13, so that the material rake 6 is in contact with the ground, and then the repair can be carried out, which is more convenient, quick and safe.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
