Definitions
- the invention relates to an agricultural attachment for the mobile cleaning of harvested crops, in particular straw crops, operated on an agricultural vehicle.
- the harvested crop referred to in the present invention is harvested crop that has been mown on an area and is lying on the mown area.
- the mowing as well as the picking up and cleaning of the harvested crop can in principle be carried out in a common operation or in consecutive operations operations take place.
- stalks are understood to mean stalk-like biomass. These include, in particular, straw and grassland or hay plants, such as grasses, herbs or legumes, which can be used as food or as fodder or silage or as bedding for pets or farm animals.
- a large number of agricultural attachments are known for picking up the harvested crop.
- Such agricultural attachments are usually coupled to a front or rear lifting device of a vehicle, in particular a tractor, a Unimog or a similar off-road vehicle.
- the agricultural attachments are operated mobile via an auxiliary drive, usually a PTO shaft, of the vehicle.
- the attachment To pick up the harvested crop, the attachment comprises a rotating pick-up unit with axially protruding tines, a so-called pickup, a conveyor belt that is arranged behind the pick-up in relation to the direction of travel of the vehicle and rotates transversely to the direction of travel, and one or more suction fans.
- the harvested crop picked up by the pickup is sucked onto the conveyor belt by means of at least one suction fan and ejected on an ejection side of the attachment, being deposited on the ground as evenly lined swaths.
- EP 3 058 805 B1 specifies an alternative agricultural attachment for raking or merging crops, with the crop being conveyed transversely instead of the conveyor belt by means of a rotationally driven auger conveyor that extends horizontally and longitudinally transversely to the direction of travel of the vehicle.
- the crop swathed in this way can contain a high proportion of foreign particles, such as raw ash, sand or small stones, so that a downstream cleaning process is required to ensure that the crop is of sufficient quality as bedding or animal feed to be able to use.
- foreign particles such as raw ash, sand or small stones
- the object of the present invention is to optimize an agricultural attachment of the generic type in such a way that harvested crops, in particular stalks, are cleaned mobile with a high degree of cleaning and with improved economy.
- the agricultural attachment according to the invention should enable efficient cleaning of crops for animal feed and bedding material. Due to new guidelines on animal welfare, stables will be increasingly coated with straw and litter in the future.
- the attachment has the features of patent claim 1 in order to achieve the object. Accordingly, the attachment has an attachment frame that can be coupled in a height-adjustable manner to a front and/or rear lifting mechanism of the vehicle, which is supported on the lifting mechanism and/or on wheels standing on the floor, a fan held on the attachment frame, and a cleaning unit held on the attachment frame.
- the cleaning unit comprises: a pick-up for picking up the crop to be cleaned with a drum which, during operation, extends longitudinally transversely to the direction of travel of the vehicle and rotates in the opposite direction to the direction of travel, which drum has a plurality of radially protruding and axially distributed tines, one in operation in relation to the
- a first air distribution floor held on the mounting frame in the direction of travel behind the receiving unit and connected to the fan via an air duct with a first air outlet
- a conveyor unit held on the mounting frame behind the first air distribution floor in relation to the direction of travel, conveying transversely to the direction of travel, via which the Harvested crop can be evaluated from the cleaning unit towards an ejection side and a drop sieve held congruently under the conveyor unit on the mounting frame.
- an air flow is sucked in by the fan, guided under the first air distribution floor and blown out counter to gravity through the first air passage in such a way that the crop picked up by the pickup is transported on to the conveying unit.
- the pick-up and the conveying unit of the cleaning unit as well as the fan are driven by an auxiliary drive of the vehicle.
- Guide plates are preferably held on the attachment frame, which prevent the crop from being blown out into the environment by the air flow or which deflect the crop accelerated by the air flow so that it engages in the conveying unit.
- An advantageous position for a deflection plate is, for example, on a rear side of the cleaning unit that is opposite the pickup and is located behind the conveyor unit.
- the deflection plate is designed here, for example, as a rear wall.
- the direction of rotation of the rotating components is based on their upper half, starting from an axis of rotation. This means that when the top half of the rotating components are moved away from the direction of travel, the rotation occurs in the opposite direction to the direction of travel. The rotation occurs co-currently with the direction of travel when the top half of the rotating components are moved toward the direction of travel.
- the particular advantage of the invention is that the crop picked up by the pick-up above the ground can be gently cleaned of foreign particles such as raw ash, soil, stones and the like by the air flow blown out through the air passages and by the drop sieve below the conveyor unit, with the Components are driven via the vehicle's power take-off.
- the attachment according to the invention is highly economical because it has a structurally simple and compact structure.
- the tines of the pickup are preferably arranged in several radially evenly distributed rows of tines. In operation, they are preferably close to the ground, i.e. kept a few centimeters above the ground, so that as little raw ash as possible is removed is picked up by the crop to be cleaned and at the same time an economical working speed can be achieved. During operation, the tines convey the crop to be cleaned up to the first air distribution floor.
- the air flow sucked in by the fan and blown from below through the first air passage via the air duct blows dusty or light foreign particles, such as grass pollen or blossoms, into the environment and transports the harvested crop on to the conveyor unit.
- insects carried along as foreign particles can fall through the falling sieve during cleaning and advantageously escape alive.
- the foreign particles filtered out via the air distribution tray and the drop sieve are preferably collected in a bunker arranged below the drop sieve or air distribution tray. This prevents the foreign particles from falling back onto the floor. In organic farming in particular, this prevents wild herb or weed seeds or the like from falling onto the ground and being able to sprout.
- the harvested crop cleaned in this way exits the ejection side of the cleaning unit preferably as a swath on the ground.
- the content of foreign particles in the cleaned harvested crop is sufficiently low that the harvested crop can be collected and further processed as fodder or bedding without further cleaning processes.
- the drum of the pickup, the first air distribution floor and the conveyor unit preferably have approximately the same length and are oriented parallel to one another.
- the cleaning unit can be designed to be particularly compact.
- two lower links are held at the same height as a fork and one is in the middle above the lower links held top link held on the mounting frame.
- the links have two or more vertically distributed, horizontally oriented through-holes for the passage of connecting means, so that they can be adapted to the vehicle's lifting mechanism at different heights.
- Conventional connecting means for example shafts or bolts oriented transversely to the direction of travel, can be passed through the through-holes in the links.
- the links preferably have recesses in which catch hooks can engage at suspension points of the hoist.
- auxiliary connection means can be adapted to the link, for example for connection to a quick coupling triangle of the lifting gear.
- the cleaning unit comprises a distributor which is held above the pick-up and at a height between a drum axis of the drum of the pick-up and the first air passage, which distributor has a shaft rotating in the opposite direction to the drum of the pick-up with distributor prongs protruding radially from it and arranged in an axially distributed manner and, in use, is powered by the vehicle's power take-off.
- the distributor which is also driven in rotation and also partially by the air flow blown out of the air passage arranged underneath, therefore acts as a material accelerator for the crop picked up by the pick-up and whirled up by the air flow and conveys it on to the conveyor unit.
- the conveyor unit is a belt rake.
- a belt rake refers to a conveyor belt that is driven in rotation transversely to the direction of travel of the vehicle or a conveyor chain that is driven in rotation and has tines projecting radially and tangentially therefrom.
- the conveyor belt or the conveyor chain is guided continuously around at least two rollers, with at least one roller being driven during operation.
- An advantage of the belt rake is its comparatively low mass and its simple integration into the cleaning unit, which means that there is no need for complex storage.
- the belt rake is held at a distance above the drop sieve so that its rotating tines scrape the crop lying on the drop sieve towards the ejection side.
- the conveyor unit is a conveyor screw.
- the screw conveyor extends horizontally and longitudinally transversely to the direction of travel of the vehicle and is driven in rotation via the auxiliary drive of the vehicle. It has a core and a helical thread which, when rotating during operation, conveys the crop to the ejection side out of the attachment.
- the core ensures that the crop does not wrap itself around the auger.
- particularly elongated stalks can be broken and shortened when engaging in the screw conveyor.
- the conveying screw is preferably mounted on a first screw end opposite the ejection side of the cleaning unit and cantilevered on a second screw end opening into the ejection side.
- the auger is designed to be open at the end on the ejection side and can eject the crop being conveyed along a direction of longitudinal extension of the auger transversely to the direction of travel of the vehicle.
- the cleaning unit comprises two or more conveying units that are parallel to one another. Between the conveyor units, a further distributor rotating in the opposite direction to the pickup is preferably held on the mounting frame above the conveyor units. At least one further air distribution base connected to the fan via the air duct and having a further air passage is preferably provided between the conveying units such that during operation part of the air flow is blown out through the further air passage.
- the screw conveyors can each be individually switched on and/or switched off depending on the need for conveying capacity or can be coupled and/or uncoupled to the power transmission means operatively connected to the auxiliary drive of the vehicle.
- a plurality of first air passages are provided in the first air passage base or a plurality of further air passages are provided in the further air passage base.
- the air passages are preferably arranged in the air passage floors, distributed uniformly over a width of the conveyor unit. They are opened in such a way that, during operation, the air flow can flow out diagonally opposite to gravity and to the direction of travel of the vehicle.
- the gravity sieve is channel-shaped and shaped correspondingly to the conveying unit or is designed to run towards the ejection side with a finer sieve or finer mesh. If the conveyor unit is designed as a conveyor screw, the gravity sieve has a correspondingly curved cross section. If the conveying unit is designed as a belt rake, the drop sieve has a correspondingly shaped, essentially U-shaped cross section. A height difference between the conveyor unit and the drop sieve is preferably adjustable and can be designed to be constant or variable over the course of the longitudinal extension of the conveyor unit.
- the wheels of the mounting frame are held on the mounting frame such that they can be adjusted in height or pivoted in relation to a vertically oriented axis.
- the front wheels in relation to the direction of travel of the vehicle during operation are preferably designed as jockey wheels or supported by additional jockey wheels, so that uneven ground can be compensated for during operation and the tines of the pickup are prevented from raking into the ground.
- the height can be adjusted in a structurally simple manner, for example, by means of a vertically oriented adjusting screw guided through the attachment frame in conjunction with screw nuts.
- the attachment is coupled to a rear lifting mechanism of the vehicle, or two cleaning units are included.
- the cleaning units are pivotably held on the mounting frame by means of a telescopic or pivotable extension arm in such a way that the drum of the pickup and the conveyor unit are pivoted out into an operating position transverse to the direction of travel during operation and into a non-operating position parallel to the direction of travel during non-operation direction of travel are pivoted.
- Pivoting preferably takes place via an adjustment element which is held between the cantilever arm and the mounting frame, can be actuated from the vehicle and is driven by the power take-off.
- the adjustment element is preferably designed as a hydraulic cylinder, which is operated via a hydraulic pump operated by the auxiliary drive of the vehicle.
- the cleaning units can be held on the attachment frame at the same height in relation to the direction of travel of the vehicle, either in alignment with one another or offset from one another.
- Each cleaning unit can have its own fan and air duct assigned to it, or a central fan can be assigned to the cleaning units together, with the air duct having two strands in some sections, so that the air is distributed to both cleaning units.
- the conveyor units of the cleaning units are driven in opposite directions to one another during operation and the ejection sides of the cleaning units are preferably at the same distance from a longitudinal center of the vehicle such that the cleaned harvested crop is preferably ejected at the level of the longitudinal center of the vehicle.
- the cleaned harvested crop is thus advantageously deposited on the ground as a swath that is easy to collect.
- two free-clearing rotors with a vertically oriented rotor axis and, during operation, close to the ground, vertically oriented rotor tines are held on the mounting frame.
- the clearing rotors are arranged in front of the pickup relative to the direction of travel and aligned with the rear wheels of the vehicle. They are driven in counter-rotating manner via the auxiliary drive of the vehicle in such a way that crops run over by the vehicle are brought transversely to the direction of travel in front of the pickups of the cleaning units.
- crops that have been flattened by the vehicle can also be picked up and are already roughly pre-cleaned by the raking free-clearing rotors.
- a transfer case held on the mounting frame is included, which is connected to the auxiliary drive of the vehicle by means of a cardan shaft.
- An output torque of the transfer case is distributed to the components of the attachment to be driven by means of power transmission means, which are preferably designed as belts, belt pulleys, chains, gear wheels or additional gears.
- power transmission means which are preferably designed as belts, belt pulleys, chains, gear wheels or additional gears.
