The abrasion resistance of the middle slot of the scraper machine means that it can save cost, improve work efficiency and increase the service cycle of the scraper conveyor. Generally, the abrasion is mainly in the middle and the groove side, especially in the joint of two slots. Therefore, Henan Shuanzhi put forward improvement measures.

Adopt high strength wear-resisting material

At present, the scraper conveyer common material is high manganese steel. High manganese steel strength, wear resistance are better, but this material also has shortcomings. Faced with complex underground working environment, high manganese steel has poor corrosion resistance, easy to rust and short service life. Although high manganese steel has good wear resistance, it will consume a lot of energy due to its high friction coefficient. In order to improve the defects of the current central trough, materials with good wear resistance, low friction coefficient and corrosion resistance should be used. For example, new materials should be selected to design the chute of scraper conveyor, and monomer casting nylon should be selected as the main material of the central trough.

Strengthen the surface of the middle trough

Strengthening the surface of chute can not only reduce the friction distance between scraper and chain in the middle trough, but also improve the service life of the middle trough. At present, the chute is made of high manganese steel. In addition to changing the composition, it is necessary to strengthen the treatment during the improvement process. Drr-2 numerical control technology can be used to partially cover the surface of the middle slot to enhance the wear resistance of the material. Strengthening the surface of chute can not only reduce the friction distance between scraper and chain in the middle trough, but also improve the service life of the middle trough.
