Definitions

  • the present invention relates to a device for feeding cattle, comprising a storage container for feed in the form of bulk material, a feed belt formed by a conveyor belt for presenting the feed to the cattle and a discharge device for discharging the feed from the storage container onto the feed belt.
  • Such devices are used to make work easier in automated or industrialized livestock farming in addition to mobile feeding robots, rail-mounted feed mixers or distribution wagons to feed bulk forage, for example basic forage such as hay, silage, maize, sugar beet pulp, etc. mixed with concentrate, to the cattle.
  • the aim is to have as high a basic feed intake as possible in order to optimize the milk or fattening performance of the cattle.
  • One way of reducing the amount of remaining feed is to add a larger proportion of tasty concentrate to the basic feed in order to make the cattle more willing to eat.
  • a mixer e.g. a mixing screw
  • this not only causes increased costs, it also requires a mixer, e.g. a mixing screw, to be installed in the storage container in order to mix the concentrate into the basic forage in a quantity-controlled manner, with a correspondingly high expenditure of energy.
  • the object of the invention is to create an automatic feeding device with which cattle can be fed in a cost-effective and energy-efficient manner. This object is achieved with a device of the type mentioned at the outset which, according to the invention, has a recycling device which is designed to return feed discharged onto the feed belt into the storage container.
  • the remaining feed on the feed belt is not wasted feed, but is returned to the storage container via the recycling device, so that it is re-mixed into the fresh feed there and presented to the cattle again.
  • the recycling device can work continuously or periodically; In these cases, too long a dwell time of uneaten feed on the feed belt and the associated putrefaction and hygiene problems are avoided.
  • the constantly new feeding incentive can also save on expensive concentrated feed.
  • either the amount of concentrate initially added to the basic feed can be reduced or it only needs to be added at all when the feed quality for the first time noticeably declines for the cattle after repeated recycling.
  • the same feed intake can be achieved with less concentrate use or a higher feed intake can be achieved with the same concentrate use;
  • the device according to the invention can be used to significantly increase the basic-to-concentrate ratio.
  • the feed is constantly mixed by recycling, so that a separate one There is no mixing device in the storage container, which significantly reduces the energy required by the feeding device.
  • the feed belt protrudes away from the storage container, so that it is accessible on both sides for livestock, Lich.
  • twice the amount of cattle can be fed at the same time, thus reducing stabling costs; on the other hand, for a given amount of cattle, the feed belt length can be halved, which considerably reduces the requirements for the stable, pasture or enclosure dimensions.
  • the length of the feed belt represents the feeding table from which the cattle eat.
  • the feed belt can run very slowly and continuously fed by the discharge device, or it starts periodically for a feeding and discharge interval.
  • the feed belt can only ever run in one direction, and the recycling device either removes the remaining feed from the entire feed belt or only from its conveyor end.
  • the recycling device can be designed, for example, as a removal or suction system that is guided over the feed belt or is arranged to the side of it, in the latter case as a return conveyor system connected to the conveyor, e.g. as a downstream conveyor belt leading back to the storage container.
  • the feed belt can be driven reversibly.
  • the feed belt can be used in one conveying direction, the "discharge direction", for discharging the feed and in the other conveying direction, the "recycling direction", for recycling the unused remaining feed.
  • One end of the feed belt can also be used as an additional feeding place for the cattle.
  • the discharge device and the recycling device can also be arranged at one end of the feed belt, that is to say that the discharge device discharges the feed onto one end of the feed belt and the recycler returns the feed from that end to the reservoir.
  • the device can currently be switched to a pure mixer operation in which the feed belt runs exclusively in the recycling direction and any feed discharged thereon is immediately returned to the storage container without it being distributed in the conveying direction over the feed belt and the cattle for consumption is presented.
  • the recycling device is formed by an ascending conveyor which connects to the feed belt at its lower end and which opens with its upper end into the upper region of the storage container.
  • the feed runs through a height difference in the ascending conveyor, so that it then covers a fall distance in the storage container, which enables effective loosening, ventilation and mixing of the remaining feed into the feed in the storage container with little energy expenditure.
  • the ascending conveyor can be constructed in any way known in the art, e.g. as a screw conveyor, elevator, pneumatic conveyor, etc. . This represents a particularly inexpensive and energy-efficient way of conveying the recycled feed.
  • the inclined conveyor belt along the storage container allows the feed belt to protrude as far as possible at the end of the storage container and the recycled feed at the opposite end of the Feed the storage container in this.
  • the first cross conveyor belt connected to the ascending conveyor belt can then can also be operated separately, e.g. to feed special feed into the storage container.
  • the first cross conveyor belt can be driven reversibly and protrudes laterally from the storage container.
  • the first cross conveyor belt thus represents, as it were, a switch connected downstream of the ascending conveyor belt, u.zw. to switch between mixer operation, when it is conveying in the direction of the storage container, and an emptying operation, in which it conveys feed out of the device via the lateral protrusion, e.g. into a disposal container below. If the discharge device simultaneously discharges feed onto the feed belt running in the recycling direction, the entire storage container can be emptied with it.
  • the recycling device opens into the storage container on one side and the discharge device discharges the feed onto the feed tape on an opposite side of the storage container.
  • the remaining feed in the storage container covers a long distance when it is recycled, which means that it is particularly well mixed with the feed in the storage container.
  • the recycling device can be formed by a section of the feed belt itself protruding into the storage container. Such a recycling device does not require any additional components and is therefore particularly simple and inexpensive.
  • the discharge device can be any conveyor device known to those skilled in the art for bulk material, for example a screw conveyor, push floor, gravity conveyor, pneumatic conveyor or the like is inexpensive.
  • the discharge device preferably has a scraper floor running on the bottom of the storage container.
  • Such a scraper floor is an effective means of conveying various types of feed in a manner that is gentle on the feed, utilizing the entire bottom of the storage container as a conveyor line.
  • the discharge device also has a metering roller which is arranged in the storage container above the conveying end of the scraper floor and can be driven counter to its conveying direction when viewed from the scraper floor.
  • the metering roller preferably designed as a spiked roller, enables particularly easy controllable feed discharge and additional mixing and loosening of the feed during discharge.
  • whole round bales of forage can be filled into the storage container, which are broken up and loosened by the dosing rollers.
  • the direction of rotation of the metering roller against the movement of the scraper floor improves the loosening of forage close to the ground and its mixing with forage in higher layers. Due to the arrangement of the metering roller at the end of the conveyor section of the scraper floor, it covers the feed with only one side, which reduces the torque required for rotation and thus the energy costs of the device.
  • the feed can also be loosened, mixed and metered.
  • the scraper floor or the dosing roller (s) can discharge the feed directly onto the feed belt. If, for reasons of building space optimization or requirements in the stable, normal discharge is to be made in the conveying direction of the scraper floor, in a further preferred embodiment the scraper floor or the metering roller (s) can be transverse to the conveying direction of the scraper floor a second cross conveyor belt opening onto the feed belt will be arranged nachge. As a result, for example, the recycling device and the feed belt can run along the same side of the storage container.
  • the device of the invention is particularly suitable for fully automatic operation, in which extended feeding intervals, in which the cattle eats the feed discharged from the feed belt, alternate with short recycling intervals in which feed not eaten by the cattle is returned to the storage container. Due to the almost permanent supply of feed, which is only interrupted by short recycling intervals in which the feed is refreshed and replaced, there are no fights or hierarchical feed access structures as is common when several hungry animals are fed at the same time; each animal can maximize its individual feed intake. The animals eat at different times so that one feeding place can be used for several animals and housing costs can be reduced. Last but not least, the even feed intake throughout the day means that the pH value in the cattle stomachs is not subject to fluctuations, which has a positive effect on animal health and performance.
  • the device of the invention comprises a control unit which controls the recycling device and which is designed to cause the feed back through the recycling device when a predetermined time interval has elapsed.
  • a control unit which controls the recycling device and which is designed to cause the feed back through the recycling device when a predetermined time interval has elapsed.
  • the device of the invention comprises a fill level sensor for the feed belt and a control unit connected to this, which controls the recycling device and which is designed to With a minimum filling level of the feed belt, the feed that has been discharged can be returned by the recycling device.
  • the feeding interval depends on the eating behavior of the cattle.
  • a single fill level sensor is essentially sufficient for the entire feed belt, since cattle usually empty it evenly.
  • several fill level sensors could also be distributed over the feed belt and / or the presence of the minimum fill level could be assumed for a certain period before the control unit initiates the return of the feed.
  • control unit initiates the return of the feed dispensed by the recycling device either when a predetermined time interval has elapsed or when the feed belt is minimally full.
  • the level sensor of the second variant can be implemented in any way known in the art, e.g. as a light barrier, laser scanner, proximity, distance or distance sensor, scales, camera with level detection unit, etc.
  • the level sensor has at least a first Open the flap, which is suspended above the feed belt so that it can pivot about an axis running transversely to this and is provided with an inclination sensor.
  • Such a level sensor is simple and inexpensive and has no measured value distortions due to the presence of livestock.
  • this level sensor can be designed to be so robust that it can withstand contact with cattle without being damaged.
  • the measurement of the filling level of the feed belt can also be used for the controlled discharge and presentation of the feed if the control unit also controls the feed belt and is designed to stop the discharge device and the feed belt when the feed belt is at its maximum level redesignendbe rich of the feed belt attached or stopping only after A waiting time has elapsed in order to ensure that the feed belt is fully loaded.
  • the device of the invention comprises a flow sensor for the discharge device and a control unit connected to this, which is designed to control the discharge device and / or the feed belt as a function of the measured flow.
  • the discharge process can be optimized with regard to discharge time and energy consumption. If the flow rate is too low, the discharge speed of the discharge device can be increased and / or the feed belt driven more slowly in order to guarantee a minimum level; whereas if the flow rate is too high, the discharge speed of the discharge device can be slowed down and / or the feed belt can be driven faster in order to avoid a jam of feed.
  • the conveying speed of an ascending conveyor connected to the control unit if available, could also be controlled, e.g. in mixer operation.
  • the flow sensor could, for example, be implemented as a mass or volume flow sensor.
  • the flow sensor has a second flap which is suspended between the discharge device and the feed belt so that it can pivot about an axis extending transversely to the discharge direction and is provided with an inclination sensor. From the measurement of the height of the feed level in the discharge device based on the deflection or inclination of the flap, the known flap width and the known conveying speed of the discharge device, the associated volume flow can be determined with sufficient accuracy.
  • the flap is again simple and inexpensive and can be made so robust that it survives contact with cattle without damage. Furthermore, the flap can be used to prevent livestock from accessing the discharge device.
  • the length of cut of long-fiber forage is of great importance for the fattening and milk yield.
  • the feed can either be pre-cut into the Vorratsbe container or cut in a cutting unit of the device.
  • the discharge device or the recycling device has a cutting mechanism. Because only discharged or recycled feed is cut in this way, the feed can be subjected to a defined number of cutting processes and thus be reduced to a length that is optimized for maximum fattening or milk yield.
  • a particularly energy-efficient cutting of the feed is achieved if the cutting mechanism is arranged in a feed fall section in the discharge device or the recycling device.
  • the cutting mechanism contains a knife roller, which interacts with a stationary knife comb in a first direction of rotation and conveys it past it in a second direction of rotation.
  • the two directions of rotation of the knife roller enable selective cutting or non-cutting of the forage.
  • the direction of rotation of the knife roller can also be controlled by the control units discussed above.
  • the storage container for enticement is provided with a feed device for adding concentrated feed to the feed.
  • the feed device can be connected to a control unit in order to bring about an automatic addition of the concentrate. It goes without saying that all mentioned control units of the device can be implemented by a single control unit.
  • the device of the invention can be used both in the open air, for example in enclosures, on pastures, etc., as well as in buildings, in particular in stables. Since stables often have already concreted, stationary feeding tables, it is particularly favorable when the feed belt is designed to be placed on a stationary feed table.
