Scraper Conveyor is one kind continuous transport equipment with flexible traction component. It has the rectangle smoothly in the seal or in the "U"shape section material trough, with the aid of in the movement scraper chain link thrust force, causes the material and the scraper chain link becomes a continual whole to transport.In the process of transportation,the scraper chains are buried in the material, so it also named "embedded scraper conveyor".This machine is one of main conveying equipment for grain process plant and grain warehouses.

Main structure
Scraper Conveyor is composed of trough,scraper chains,head wheel and tail wheel,inlet and outlet,drive device and tensioning device.
 
Working principle
1)  Horizontal Transport
When horizontal transportation, under the scraper chain direct action, the hauling level and is towed between the level material the anelasticity to be bigger than the trough wall to tow the level material the outside friction force, like this tows the level and the hauling level material forms a whole, forward transports together under the scraper thrust force function.
 
2)Vertical Transport 
When Vertical transportation, materials in the vertical direction by the scraper thrust, own gravity and material on the bottom of the vertical to upper material support of the vertical pressure for a certain proportion of lateral transfer, the formation of materials and materials on the walls of the lateral pressure trough, and a lateral pressure between the relative stability of the materials within the friction and prevent movement of friction materials, and traction and traction of the internal friction between layers of materials sufficient to overcome the friction with the trough where the gravity and materials, thus forming a stable materials in the overall thrust of the scraper chain conveyor forward.
 
Feature
1) Simple structure,light weight,small volume,it is convenient to manufacture ,install ,use and maintain.
2) The sealing property is good, the dust does not spread.
3) simple feeding device and discharge device,it can multiple feeding,multiple discharge.
4) Technology layout flexibility, can be used for the transportation of materials in different directions.
5) Scraper chain and trough easy to wear.
6) Transport higher moisture materials, making it easy for a adhesion and compaction, prone floating chain
