Abstract
The chopper has a control zone arranged between a forward conveyor belt and cylinder and a rear conveyor belt and cylinder. The zone consists of an inspection plate, which receives the material from the front conveyor and passes it to the rear conveyor, located before the chopper. A set of spring loaded sensor elements are supported on a cross member which is connected to a flywheel and which is lowered in a guide. The sensors protrude through a cover and press any foreign body against the inspection plate. This initiates a train of operations resulting in the interruption of the drive to the conveyors, thus protecting the chopper from ingress by a foreign body.
