Title:
FEEDER
Document Type and Number:
WIPO Patent Application WO/2013/044274
Kind Code:
A3
Abstract:
This invention relates to a feeder. More specifically, the invention relates to a secure feeder for feeding material onto a conveyor belt enclosed in a pipe, generally known as a pipe conveyor, preventing access to the material being transported thereby. The feeder includes a container, a flow regulating member and a flow restricting member. The container defines a loading end for receiving material and a discharge end for discharging material into the conveyor belt. In use, the flow regulating member regulates the flow of material through the discharge end of the container while the flow restricting member restricts the flow of material deposited on the conveyor belt to an upstream-to-downstream direction thereby preventing the backflow of material in an opposite downstream-to-upstream direction. Furthermore, the flow restricting member comprises a free end positionable in use in contact or close proximity with the conveyor belt.
