The Scraper Conveyor is a type of continuous transport equipment, designed with an innovative flexible traction component.
Featuring a rectangular or 'U'-shaped material trough, this conveyor employs a moving scraper chain link thrust mechanism. This ensures materials and scraper chain links unify, forming a seamless transport system. Often called an 'embedded scraper conveyor' due to the scraper chains being buried in material during transport, this machine is essential for grain processing plants and warehouses.
Main Structure
The Scraper Conveyor consists of the following components,scraper chains,head wheel and tail wheel,inlet and outlet,drive device, and tensioning device.
Working Principle
1) Horizontal Transport
During horizontal transport, the direct action of the scraper chain creates a level hauling force. This force, combined with the friction between the hauled level material and the trough wall, enables the material to move as a unified entity. The material is then transported forward under the scraper's thrust.
2)Vertical Transport
In vertical transportation, materials are moved upward by the scraper's thrust, gravity, and the vertical pressure from materials below. This creates lateral pressure between materials, stabilizing them and preventing movement due to internal friction. This stability allows the scraper chain to transport materials vertically in a seamless, continuous motion.
Features
1) Simple structure,lightweight,compact size,easy manufacturing,installation,usage, and maintenance.
2)Excellent sealing properties prevent dust dispersion.
3) Simple feeding and discharging mechanisms allow for multiple feedings and discharges.,multiple discharges.
4) Flexible technology layout for multi-directional material transport.
5) Scraper chain and trough are prone to wear.
6) Effective in transporting high-moisture materials, though it can lead to adhesion, compaction, and floating chain issues.
