Definitions

• the invention relates to a loader bucket, a loader bucket that is used when connected, for instance, to the lifting device of a tractor or corresponding vehicle.
• a screwlike device has been placed inside the loader bucket, the said device enabling material scooped into the bucket to be processed before being discharged from the bucket.
• a device such as the one mentioned above is described in the German application publication 2 353 789, the said device being intended to be used in the proportioning of animal fodder.
• the batch of fodder to be proportioned is scooped into the loader bucket and is thereafter fed to the selected spot by means of a feed screw located on the bottom of the bucket and passing through the end wall of the bucket.
• the device can, for instance, be driven along the feed trough of a line of animals and thereby be used to proportion the fodder to be within their reach.
• the German patent 34 02 269 is the origin of a prior art bucket structure for attaching to a digger or correspon ⁇ ding base machine.
• the said bucket has been made into a extruder for the purpose of compacting clay, peat or the like and then extruding these in rodlike form.
• the mate ⁇ rial to be compacted is scraped into the bucket where it is then compacted by means of the bucket lid which is forced down on the material.
• the bucket may contain con ⁇ tinuous screw conveyors acting as mixers to homogenise the material scraped into the bucket. In addition to the mixing effect, these devices are required to provide ef ⁇ ficient transportation of the material to the point of extrusion.
• the loader bucket in accordance with my application is primarily and expressly a device that must possess good mixing characteristics in order to fa ⁇ cilitate the efficient mixing of the material taken into the bucket.
• the bucket in accordance with my application is intended for the forming of compost heaps. Dung for composting and a composting ingredient such as peat are scooped into the bucket. These are mixed together inside the loader bucket and the loader bucket is then used to pile the mixed material to form compost heaps.
• FIG. 2 shows the loader bucket plus the operating devices of the mixing devices as seen from behind
• Figure 3 shows an end view of the loader bucket, the said end being the location of the gear devices transmitting the operating power to the mixing de ⁇ vices.
• the basic part of the loader bucket 1 consists princi ⁇ pally of a conventional loader bucket that can be attach ⁇ ed to the lifting devices of a tractor or corresponding vehicle.
• two trans ⁇ verse shafts 2 are placed crosswise to the loader bucket 1 and in the vicinity of its end wall, the said shafts deriving their operating power via two chain sprockets located on the outside of the other end wall. These chain sprockets derive their operating power via a chain 5 driven, for instance, by a hydraulic motor connected to the tractor's hydraulic system.
• Mixing blades 3 have been installed in the manner of a screw line pattern on either of the shafts 2, the orien ⁇ tation of the said blades resembling essentially that of the screw line pattern.
• An essential feature of the in ⁇ vention is that the spiral screw is formed expressly of blades of the type described here, the said blades being fully separate from one another in the implementation manner here presented.
• the base of the screw is of a continuous structure, but blades of the type here described protrude from it.
• the mixing blades 3 can be grouped into more than one series along the shafts 2. The orientation of the screw pitch of the series may differ from one another.
• the direction of rotation of a particular shaft may be directed to be opposite to that of an adjacent shaft. It is also possible to have the all rotation directions changed to the opposite by changing the direction of ro- tation of the drive device 6. These measures can be used to adapt the device's mixing capacity to meet the needs of various situations.
• the mixing devices can also be constructed in such a manner that they can be detached from the loader bucket and thereby allow the loader bucket to be used for other purposes.
• the loader bucket in question is used expressly for the purpose of forming compost by scooping dung or liquid manure and auxiliary composting ingredients, such as peat or the like, into the loader bucket. These materials are mixed in the loader bucket and are then discharged to form the compost heap.
