During use, the staff first moves the device to the bottom of the scraper chain plate, and then manually operates the pressure rod to move the pressure rod up and down, and then transmits power to the hydraulic cylinder through the three-way valve and the hydraulic oil pipe. At this time, the telescopic end of the hydraulic cylinder moves forward, thereby shortening the distance between the extrusion head and the cone head. At this time, the extrusion head and the cone head are aligned with the gap between the scraper chain plates and wedged into them. As the extrusion head continues to move forward, the wedging amount increases, so that the joint surfaces of the two chain plates can be separated, the pin shaft is disengaged, and the chain plate is disassembled. The use of this device can realize the rapid disassembly of the scraper chain plate, shorten the maintenance time, improve the working efficiency, reduce the production cost, increase the output value, and eliminate the safety hazards of hammering;
[0013] 2. During use, the limiting holes and limiting columns can make the extrusion head more stable when entering the gap of the scraper chain plate, avoiding skewness and shaking, so that the disassembly can be smoother.

[0014] 3. During use, the two guide plates can guide the parts on the chain together in an orderly manner, so that the staff can use them again. The staff inserts the external facilities into the push slot, and then moves the disassembly device to the bottom of the scraper where the chain plate needs to be replaced through the universal wheel, which is conducive to the movement of the device, improves convenience and practicality, and makes it easier for the staff.
