Büffel loader wagon

The rotor loading system with holding hopper opens up a new dimension in efficiency!

The Fliegl BÜFFEL presents a completely new combination of pickup, cutting rotor, hopper and overloading apparatus. Material is taken up, cut, stored in a holding hopper and overloaded onto the transport vehicle. The Fliegl BUFFALO means continuous loading, continuous transport.

Fliegl BUFFALO: An innovative all-in-one system in loading technology.


The Büffel sees Fliegl taking its first steps into the world of forage harvesting technology with the development of a transfer trailer. In the front section, the technology is identical to that of a loader wagon; with a pick-up, rotor and cargo space. The feed is then transported to the hydraulically powered dosing rollers via the scraper floor and subsequently transferred via a conveyor belt.

Straw, hay and grass are taken up out of the swath by the pickup, chopped by an easy-pull cutting rotor, stored in the 10 m³ hopper and from there overloaded onto a transport vehicle. The harvesting process is in two phases, i.e. the Fliegl BUFFALO carries out the loading, holding, and overloading in phase one, and the removal is performed by one or more transport vehicles in phase two. This is fundamentally different from the corn shredder chain, which is organised in three phases, in which the crop is usually overloaded by the shredder onto a push-off trailer attached to a truck.

The method established by Fliegl BUFFALO is completely new: the loading assembly is continuously in operation in the field, is not involved in the removal transport, and does not have to be emptied. There is no switching between loading and transport. There are no more periods where the loading assembly is unproductive, and capacity utilisation rises to 100 percent.

The technology behind it includes a 1.50 m wide rotor with seven rows of tines and 86 cm in diameter. The 8 mm wide Hardox fingers press the feed through up to 49 knives. These can be hydraulically swivelled in and locked as well as individually secured via rocker arms and can be used on both sides. The BÜFFEL therefore creates a theoretical cutting length of only 30 mm with a very good cutting quality.

The rotor and two hydraulic pumps are driven by a T-gear below the hydraulic articulated drawbar. These supply the conveyor belt and the metering rollers at the rear with a capacity of 100 l / min at 180 bar. All other hydraulic functions as well as the speed ratio of the scraper floor and dosing rollers are controlled by the tractor.

Around 130 t of fresh mass per hour can be achieved with 200 hp. The transfer belt is 5.10 m high and reaches an overload length of 4.30 m. It can be pivoted behind the metering roller. For field use, the dosing rollers and the rear wall are folded in a funnel shape so that the belt can be fed optimally. The interior of the bunker can be perfectly controlled via a camera.

With a total weight of 8 tons the BÜFFEL is very light. The low weight combined with a length of just 6m make the BÜFFEL even in narrow terrain manoeuvrable. The up to 90 cm telescopic axle ensures perfect stability even on slopes.

Outlook


The Fliegl BÜFFEL can also be implemented as a self-propelled harvester. 

The pickup could be replaced with other attachments: Instead of the pickup, a disc mower could be used to adapt the over-loading apparatus for green fodder harvests. (For occasional operations, it could also be combined with a front mower).

 

Extendable axle –


Shifts the centre of gravity for a smoother journey

Because of the single-sided loading by the conveyor belt, there would otherwise be a risk for stability on slopes. The wheel can be extended in order to stabilise the centre of gravity.

 

Enhancements


  • Wind catcher: A wind catcher at the transfer point prevents excessive drifts
  • Foreign object separator: Strong magnets are integrated with the feed stream. Metal objects do not enter the silage, but are already removed during harvesting.
  • Synchronous conveyor belt: For light material, a synchronous conveyor belt is required to hold the material down.
  • Compaction rollers 
  • Silage additive dosing system: Granular or fluid
  • More blades: With more blades, the cut length can be reduced, and the gap to the shredder can be made smaller.

Fliegl BUFFALO: An innovative all-in-one system in loading technology.


Where is the innovation in this product compared with the previous state of the technology?

In the pickup and cutting rotor, the Fliegl BÜFFEL acts similarly to a loader wagon. Unlike a loader wagon, however, the Fliegl BUFFALO is not part of the transport chain and does not have to leave the field and be emptied like a loader wagon does. The Fliegl BÜFFEL eliminates the unproductive periods of the loader wagon.

At the hopper, the Fliegl BUFFALO works similarly to a round baler with front chamber. Compared with round balers, however, the hopper on the Fliegl BUFFALO is larger, with a completely different design.

When over-loading, the Fliegl BUFFALO works similarly to the over-loading apparatus on a corn shredder chain. Unlike corn shredders, which over-load the crops immediately, the Fliegl BUFFALO includes a holding hopper. The energy consumption of the Fliegl BÜFFEL is significantly below that of the shredders, and even below that of towed shredders.

History tells us about hay loaders and cart loaders which used to collect the hay and pass it without cutting onto a conveyor, which over-loaded it onto a towed wagon (or wagon upstream in the train). Cart loaders were completely superseded by loader wagons. Unlike those, the Fliegl BÜFFEL not only uses the most modern technology, but also contains a chopping system and holding hopper and – which is the most important and essential difference – does not overload onto a wagon in the same train, but onto a separate, independent trailer.

In other words, the Fliegl BUFFALO has brought together well-known components in a new way and, with this innovative combination, has established a way of harvesting which has never seen before, and which achieves unprecedented efficiency.

Features / advantages

Like all true innovations, the principle of the Fliegl BUFFALO is simple: the system is made up of the pickup, cutting rotor, holding hopper and overloading apparatus. Grass is collected out of the swath by the pickup, cut by an easy-pull cutting rotor, stored in the hopper, and from there over-loaded onto a transport vehicle (harvest wagon). The harvesting process is in two phases, i.e. the Fliegl BÜFFEL carries out the loading, holding, and overloading in phase one, and the removal is performed by one or more transport vehicles in phase two. This is fundamentally different from the corn shredder chain, which is organised in three phases, in which the crop is usually overloaded by the shredder onto a push-off trailer attached to a truck.

What’s completely new:

The loading assembly is continuously in operation and is never involved in the removal transport. There is no more switching between loading and transport. There are also no more idle times for the loading assembly, where the capacity utilisation rate rises to 100 percent.

Importance in practice

As a single unit, the Fliegl BUFFALO has the capability to completely reorganise the entire crop harvesting process. The transport fleet which is frequently present, and which is well known with the shredder chain, can be used in full for harvesting the crop. The capacity of the loading assembly is utilised continuously. Its impact is increased compared with the loader wagon, as is the efficiency of the crop harvesting process as a whole.

Reduced workload

If a transport vehicle is missing, over-loading stops automatically. This makes work processes easier. For example, the beacon-based detection of transport vehicles prevents loading onto the tractor cab and similar loading errors.

Work safety

On tight bends or on sloping ground, the overloading apparatus can work alone. Compared to working with two trailers, this is an alternative which brings greater safety to such situations.

2-phase harvest process


Phase 1: The Fliegl BUFFALO takes care of the loading, holding and over-loading

Phase 2: Removal by one or more transport vehicles

The over-loading apparatus can work alone

If a transport vehicle is missing, over-loading stops automatically. This makes work processes easier. Here, the over-loading apparatus and integrated hopper demonstrate their strengths to the full.
