At present, the development trend of scraper chain conveyors is: large conveying capacity, large bandwidth, large inclination, increased length of a single machine, horizontal turning, reasonable use of belt tension, and reduction of material transportation energy consumption. It is an ideal cleaning method.
The middle trough is responsible for carrying materials in the entire chain scraper conveyor, and it is made of castings and castings. Although grooves can be formed, the actual effect of the product on the chain conveyor is that there will be differences between the names, and the differences can be found in the amount of wear.
By comparing the usage of a surface, it is found that the center casting trough in the scraper chain conveyor wears very well. There is basically no deformation or damage; there is no obvious deformation or breakage at the connecting part of the rotating ear and the dumbbell pin. However, the situation of welding casting grooves is different, and there is serious wear.
The results show that the middle groove of the scraper chain conveyor is still cast as much as possible, so that the middle plate of the middle groove can be oriented along the running direction of the scraper; the total number of waves helps to reduce the scraper in the chain conveyor. The contact area of the intermediate plate greatly reduces the friction resistance of the scraper and prolongs its service life.
However, when the middle groove of the chain scraper conveyor needs to be integrally cast, the entire material is made of high strength and high abrasion resistance as much as possible, so that there are problems of desoldering and cracking in the middle plate and the bottom plate. The welded middle groove was overcome. It also avoids the situation that the groove of the other middle welding groove is easy to wear, and the friction resistance of the middle plate is relatively poor.
