We have introduced a lot about the performance of the coal mining scraper conveyor equipment. Today we are going to explain the maintenance technical guidance for you.
How to adjust the length of the chain when the conveyor is not running properly? Each connection of the scraper chain is connected by a lock shaft. There is a movable pin on the chain every 1.5m or so, which is locked by a split pin. To adjust the length of the scraper chain, when you need to remove a number of chain links, find a split pin. After opening, the chain can be disconnected from there. Remove a predetermined number of chain links, and use the original movable pins and ends of the chain ends The cotter pin can be connected and tightened.
Coal mining scraper conveyor sometimes also needs to adjust the overload pressure relief device. This is a more special device. There is a heavy hammer suspension device at the discharge end of the scraper. When there is too much material in the machine tank and it is difficult to discharge, the material can The device is lifted up, and the scraper can be stopped by touching the stroke switch above it. Rotate the suspension position of the weight on the weight suspension device and adjust the length of the lever to adjust the force required to lift the device, so as to limit the overload of the scraper. Adjusting the distance between the travel switch and the weight suspension can also achieve the purpose of adjusting the overload.
