Type – Foidin / Milled Peat
This attachment was designed and developed to permit the harvesting of foidin sods while the surface of the field and loose milled peat are wet, also to permit the harvesting of foidin sods and milled peat or all milled peat when bog conditions are favourable.
The attachment is fitted to the Harvester type III machine in place of the spiral unit and ball housing. It consists ~f an elevator conveyor which lifts the foidin or milled peat and discharges it onto a cross con¬veyor which in turn discharges onto the belt conveyor of the standard machine. The elevator comprises a light frame work fabricated in square hollow section steel with fixed sheeting top and bottom but the centre portion is fitted with hinged flaps which can be closed to complete the sheeting of the con¬veyor or left open to allow the screening out of wet mould. The conveying element is a bar screw chain passing over the partly sheeted, or when flaps are closed, fully sheeted elevator and runs on sprockets at the top and on small diameter rollers at the bottom. The complete elevator is supported on a structure cantilevered from the frame of the main machine.
The cross conveyor is rubber/canvas belting running on conventional end rollers with intermediate troughing rollers and is carried on a separate frame work supported at three points within the cantilevered frame from the main machine.
The drive to the elevator is from the gearbox normally used to drive the spirals while the belt is driven by chain and sprocket from the driving roller of the standard machine conveyor.
The attachment is lifted and lowered by hydraulically operated rope from the main machine using the standard machine equipment.
While the machine was primarily developed for lifting foidin sods in wet conditions, it lifts milled peat very effectively in the fourth and fifth lifts. The fixed speed of the potato type chain makes the lifting of the first, second and third milled peat lifts uneconomical.
