CLEANING AND SEPARATION SYSTEMS
All belts and rollers are hydraulically driven, therefore their speed can be adjusted steplessly.The ROPA Keiler has large cleaning components with maximum cleaning area for gentle and efficient cleaning. The ROPA Keiler is particularly efficient for harvesting on heavy soils and/or during bad weather.
Overview of models
KEILER 2 RK22 WITH 4 PINTLE BELTS
When it comes to a high-performance separation of crop and impurities, the Keiler 2 with 4 pintle belts has proved to be the most suitable.
KEILER 2 RK22 CLASSIC
The Keiler 2 Classic with 2 pintle belts is perfect for efficient and gentle separation of crop and impurities on light, loose soils.
KEILER 2 RK22 DOUBLESELECT
DoubleSelect is the option for increased separation performance on cloddy and stony soils.
TWIN-CLEAN
In the Keiler 2 RK22, the first lifting chain or sieve conveyor is hydraulically reversible.
Twin-Clean is the new optional split of the first sieve conveyor into a lifting chain and a sieve conveyor. Both conveyors can be operated with different pitches and at different speeds. It is useful for both quick replacement of the first lifting chain and adjustment to different harvesting conditions or when switching to onions. The sieve channel is designed in such a way that the Twin-Clean can also be retrofitted later. The height difference of the conveyors increases the sieving performance.
Hydraulic drives:
1. Shaker.
2. Sieve conveyor
3. Lifter chain
TRASH MANAGEMENT
Improved leaf chain routing and leaf retainer springs
The interaction between the leaf chain and the arrangement of the retention springs has been adapted for optimised leaf removal and improved separation as well as reducing potato losses at the same time. The pull-off rods can be easily installed if required.
Dirt discharge conveyor
The leaf chain, which can be selected in different pitches, separates leaf residues from the potato flow and conveys them to the rear of the machine.
Trash discharge conveyor
The admixtures sorted out by pintle belt 1/leaf chain and sorting staff/UFK are reliably guided via both discharge conveyors at the front and rear out of the machine, thus keeping the leaf chain clean.
Collection box
A collection tank is particularly useful on stony soils. The stones can be collected and unloaded at the specified place with the help of the hydraulically driven discharge conveyor.
WIZARD SYSTEMS
Ease of operation due to wizard systems - Automatic adjustment of conveyors
1. Drive speed-dependent control of conveyors
2. Load-depending control of conveyors
3. Speed of conveyors without automatic functions
- Optimum conveyor regulation with no additional effort due to the combination of driving speed-dependent and load-dependent control
- When the driving speed changes, the speeds of sieve conveyor 1 and 2 as well as pintle belt 1 are adjusted proportionally to the driving speed
- In case of temporary load peaks, the load-dependent control temporarily increases the speed of sieve conveyor 2 and pintle belt 1 in order to avoid reduced cleaning performance or blockages
- For particularly efficient and gentle harvesting with the automatic conveyor regulation, the minimum and maximum speed can be set individually
ROPA potato crusher
The ROPA potato crusher with integrated stone protection is a sustainable, herbicide-free and resource-saving method for reducing regrowth of potatoes in the successor crop. The potato crusher squashes and grinds the tubers, sorted out via discharge chutes and a trash track. This promotes rotting and prevents germination of potatoes in the following year.
FUNCTION AND BENEFITS OF THE ROPA POTATO CRUSHER
1. Hardox shredding knife on one crusher wheel
Small pieces are shredded from large potatoes, until they are caught by the crusher wheels, crushed and pressed through the gap
Large tubers are shredded to small pieces, caught and also crushed
2. Hydraulic drive for rubber wheels
The friction effect of the different rotational speeds of the wheels reinforces the shredding effect during crushing
The rotary speed can be adjusted by a volume regulator
3. Mechanical stone and foreign object protection pre-tensioned by spiral springs - for uninterrupted harvesting
1. Volume regulator for speed adjustment
2. Very quiet operation
- Crusher wheels not in direct contact
- The distance between the crusher rollers can be adjusted by a spindle
Rubber tyres as crusher rollers
- Low wear and tear
- Low force required
- Quiet operation with low vibration, even with high proportion of stones in the soil
- Air pressure in wheels can be adjusted
The potato crusher consists of two pneumatic tyres rotating at different speeds
Hydraulic spreading up to 300 mm for free passage
Lifting without crusher function possible
Opens to extremely large foreign objects
Sorting platform
Comfortable sorting platform
The large-dimensioned sorting platform provides enough place for up to 5 operators. Thanks to the pull-out sorting stand the platform can be extended by 300 mm. The trash conveyor, which can be independently adjusted in speed, transports the admixtures sorted out by the UFK to the right discharge chute. The discharge chutes with rounded edges reliably guide the sorted out admixtures onto the trash discharge conveyor, which can guide the admixtures back into the sieve channel 2 if required.
Working platform, 300 mm extendable - immense working area allows freedom of movement
Customised upholstered parts, a hand-washing tank and drink holders provide further comfort at the sorting platform. A folding ladder with damping and pinch protection provides easy access to the platform.
Sunshade canopy, adjustable in height
The ROPA sunshade or weather protection canopy keeps the sorting staff protected from sun and bad weather during harvesting (optional, can be extended with side panelling).
Free positioning of platforms, which can be adjusted in height
Work at the sorting platform is very comfortable, as the sorting staff can easily change the working height of the height-adjustable platforms.
