[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a return roller structure for a bucket-type dry slag machine. The return roller structure includes: a roller seat 3 and a fixed column 11 installed on the surface of the frame 1. A conveyor belt 2 is installed inside the frame 1 to facilitate material conveying in the bucket-type dry slag machine. The lower side of the conveyor belt 2 contacts the roller 13. The highest point of the arc surface of the roller 13 and several rollers 6 are on the same horizontal line. The roller 13 can support the conveyor belt 2. The roller seat 3 is detachably installed on the inner wall of the frame 1 by bolts. An arc groove 4 is opened on the lower surface of the roller seat 3, and a sliding groove 18 is opened on the upper surface of the roller seat 3. The sliding groove 18 can limit and guide the movement of the connecting plate 5. The inner wall of the slide 18 is provided with several limiting grooves 17. The connecting plate 5 is slidably connected to the slide 18. Both ends of the connecting plate 5 pass through the roller seat 3. The roller 6 can be moved by moving the connecting plate 5. The surface of the connecting plate 5 is rotatably connected to several evenly arranged rollers 6 through the interference fit of the bearing. Several sliding columns 7 are evenly fixedly connected to the other side of the connecting plate 5. The sliding columns 7 can support the connecting plate 5. The sliding columns 7 are slidably connected to the limiting groove 17. The inner wall of the limiting groove 17 is fixedly connected to a spring 8. The sliding column 7 can be limited by the spring 8. The other end of the spring 8 is fixedly connected to the end of the sliding column 7 located in the limiting groove 17. When the sliding column 7 moves, the extension and contraction of the spring 8 begins to change.

[0022] When the idler roller 13 is replaced, the sliding column 7 slides outward under the elastic force of the spring 8. At this time, it will drive the connecting plate 5 and the roller 6 to move simultaneously. When the sliding column 7 moves to its maximum value, the roller 6 reaches the bottom of the conveyor belt 2 and contacts it. At this time, the roller 6 can replace the idler roller 13 to support the conveyor belt 2. When the replacement of the idler roller 13 is completed, the roller 6 can be reset by sliding the connecting plate 5.

[0023] The surface of the fixed column 11 near the roller seat 3 is provided with a fixing thread 12. One end of the fixed column 11 passes through the roller seat 3 and is threadedly connected to it through the fixing thread 12. At this time, the position of the fixed column 11 is fixed. The sealing end cap 16 and the fixing tube 15 are both sleeved on the surface of the fixed column 11. The inner wall of the graphite bearing 14 is installed on the outer surface of the fixing tube 15 by interference fit. The graphite bearing 14 can play a self-lubricating role while rotating, without the need for additional manual lubrication, thus reducing the maintenance cost of the components. The inner wall of the idler roller 13 is sleeved on the outer surface of the graphite bearing 14. One end of both the graphite bearing 14 and the idler roller 13 is in close contact with the end of the fixing tube 15, and the other end of both is in close contact with the side of the sealing end cap 16. The sealing end cap 16 can limit and fix the idler roller 13. The other side of the sealing end cap 16 is in close contact with the end of the fixed column 11.

[0024] When the conveyor belt 2 moves, the idler roller 13 starts to rotate under the action of the graphite bearing 14 and rolls and rubs against the lower end of the conveyor belt 2, thereby reducing the wear of the idler roller 13.

[0025] A rotating shaft is fixedly connected to the inner wall of the arc groove 4. The surface of the rotating shaft is rotatably connected to one end of the rotating plate 9. At this time, the rotating plate 9 can rotate along the arc groove 4. The other end of the rotating plate 9 is fixedly connected to the end of the fixed tube 15 near the roller seat 3. The fixed tube 15 and the rotating plate 9 rotate together. The side of the locking block 10 near the roller seat 3 contacts the connecting plate 5 and is elastically connected to the rotating plate 9 through a torsion spring. The torsion spring allows the locking block 10 to remain perpendicular to the rotating plate 9 without other forces. The lower end of the locking block 10 contacts the connecting plate 5. The locking block 10 allows the connecting plate 5 to be restricted in the roller seat 3.

[0026] When the idler roller 13 needs to be replaced, rotate the fixing column 11 and remove it along the fixing tube 15. At this time, the sealing end cover 16 can be removed. Then, rotate the rotating plate 9 downward. During this process, the locking block 10 gradually disengages from the connecting plate 5. When the two are no longer in contact, the roller 6 can pop out to replace the idler roller 13 for support. Then, the idler roller 13 can be removed. When the replacement is completed, rotate the rotating plate 9 upward and move the connecting plate 5. At this time, the idler roller 13 is supported again. During this process, the connecting plate 5 contacts the locking block 10 and squeezes it to make it rotate. When the connecting plate 5 is completely inserted into the slide groove 18, the locking block 10 is reset under the action of the torsion spring, and the connecting plate 5 is fixed again. At this time, the sealing end cover 16 and the fixing column 11 can be installed in sequence.

[0027] When the device is working, the conveyor belt 2 is supported by the idler roller 13. When the idler roller 13 needs to be replaced, the fixed column 11 and the rotating plate 9 are rotated in sequence without stopping the machine. At this time, the roller 6 pops out to replace the idler roller 13 and support the conveyor belt 2. After the replacement is completed, the rotating plate 9 is rotated and the connecting plate 5 is moved. Then the fixed column 11 is installed, and the position of the roller 6 can be fixed by the locking block 10. The device can replace the idler roller 13 without stopping the machine.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
