[0026] Furthermore, if Figure 2 As shown, the steps for using the scraper disassembly device are as follows: First, the operator needs to open and organize the folding tool box 1, ensuring that all tools are in easy-to-access and good condition. Next, follow the steps below one by one: Prepare the pneumatic wrench: Take out the pneumatic wrench from the folding tool box 1 and make sure it is connected to the air source and the pressure is properly adjusted. The operator holds the pneumatic wrench close to the locknut 7.2 on the scraper and easily removes the locknut 7.2 one by one by quickly rotating it and using the efficient torque of the pneumatic wrench.

[0027] Using the retractable mechanical stick: Then, select the retractable mechanical stick 1.5 from the tool box and adjust it to a suitable length so that the entire device can be lifted stably.

[0029] Lift the scraper to create a gap: After ensuring that the mechanical claw 5 has firmly grasped the scraper 7.1, operate the control panel 1.4 again to control the mechanical claw 5 to slowly rise and lift the scraper 7.1 from its original position, thereby creating a sufficient gap between the scraper 7.1 and the conveyor structure. This gap provides the necessary space for the subsequent use of hydraulic shears to cut the connecting bolts 7.2.

[0030] Cutting the bolts: At this point, the operator takes out the hydraulic shears from the tool box and uses their powerful shearing force to align the hydraulic shears that extend into the gap and cut the bolts 7.2 that connect the scraper to the conveyor structure. The efficiency and precision of the hydraulic shears ensures that the bolts are cut quickly and without damage.

[0031] Rotate and lift the scraper: After the bolts are cut, operate the control panel 1.4 again to control the mechanical claw 5 to drive the scraper 7.1 to rotate, so that the scraper 7.1 is completely freed from the constraint of the middle groove. Then, continue to control the mechanical claw 5 to lift the scraper 7.1 to a sufficient height for safe removal.

[0032] Remove the scraper and clean it: After the scraper 7.1 is completely detached and in a stable state, the operator can easily take out the cross plate 7.4 and the cut bolts 7.2 together to complete the removal of the scraper 7.
