Rapeseed separator
A rapeseed cutter (also rapeseed side knife or rapeseed cutter) describes a device used in agriculture on the cutting unit of a combine harvester . Rapeseed cutters are used in the rapeseed harvest and are used to cut hanging branches in the rapeseed plant . In this way, harvest losses are to be reduced.
Cultivation and function
The rapeseed cutter is attached as an additional unit on the right, left or both sides in a vertical orientation on the side walls of the cutting table of the combine harvester. This vertical arrangement means that rape that is still standing remains unaffected. Specifically, the rapeseed cutter is used during the actual threshing process to loosen interlocking branches with the help of the knife. This minimizes vibrations to the rapeseed plant during the mowing process and thus the loss of grain.
Drive types
Rapeseed cutters are driven either mechanically , electrically or hydraulically via the cutter bar .
- Hydraulic rapeseed cutter
- A hydraulic rapeseed cutter is driven by the combine harvester's on-board hydraulics. To use a hydraulic rapeseed cutter, additional hydraulic hoses must be connected to the combine through which the hydraulic fluid can be supplied.
- Electric rapeseed cutter
- An electric rapeseed cutter is driven by an electric motor. It should be noted that the listed voltage of the electric motor corresponds to that of the electrical system in the combine harvester. With electrically driven rapeseed cutters, the rapeseed cutters can be switched off independently of the cutting unit.
- Mechanical rapeseed cutter
- Mechanical rapeseed cutters are driven by the gearbox and the cardan shaft of the mower.
