Definitions

  • the present invention relates to mixer feeder apparatus, and in particular, though not limited to mixer feeder apparatus for mixing animal feed comprising fibrous fodder material and nutritional ingredients.
  • the mixer feeder apparatus according to the invention may be provided as a trailable mixer feeder wagon, a self-powered mixer feeder wagon, a fixed mixer feeder wagon, or the like.
  • Mixer feeder apparatus such as mixer feeder wagons for mixing animal feed which include fibrous and other fodder materials and nutritional ingredients are known, for example, such mixer feeder wagons are disclosed in British Patent Specification No. GB-A-2, 139,911 , European Patent Specification No. EP-A-0,427,438, and PCT Published Application Specification No. WO 96/32836.
  • mixer feeder wagons are particularly suitable for mixing animal feed which comprise fibrous fodder material, and in particular, straw with other nutritional ingredients which may also be fibrous materials such as hay and silage, as well as nutritional and other additives in concentrated form, and other such ingredients.
  • These mixer feeder wagons include a container mounted on a chassis which is carried on two or more rotatably mounted ground engaging wheels, and the chassis terminates in a forward hitch suitable for coupling to a tractor or other suitable towing vehicle.
  • the container defines a hollow interior region, which in turn forms a mixing compartment within which the fibrous fodder material and other ingredients are mixed to form the animal feed, and a dispensing compartment from which the mixed animal feed is discharged from the mixer feeder wagon.
  • the container defines an upwardly facing open mouth for accommodating fodder material into the mixing compartment.
  • a mixing rotor of paddle type construction is rotatably mounted in the mixing compartment, and as the mixing rotor rotates, the paddles of the mixing rotor mix the fibrous fodder and other materials to form a homogenously mixed animal feed.
  • the dispensing compartment typically extends longitudinally along the side of the mixing compartment and is isolated therefrom by an isolating plate during mixing of the fodder material in the mixing compartment.
  • the isolating plate is operable between a closed state isolating the dispensing compartment from the mixing compartment and an open state communicating the dispensing compartment with the mixing compartment. On completion of mixing, the isolating plate is urged into the open state permitting the mixing compartment to communicate with the dispensing compartment.
  • the mixed animal feed is urged by the paddles of the mixing rotor from the mixing compartment into the dispensing compartment.
  • An auger located in the dispensing compartment urges the animal feed along the dispensing compartment and discharges the mixed animal feed through a dispensing outlet.
  • a plurality of longitudinally spaced apart blades are located in the base of the mixing compartment, which co-operate with the paddles for chopping the fibrous fodder material, and in particular, for chopping straw.
  • mixer feeder wagons are particularly suitable for mixing fibrous fodder material
  • a slight disadvantage of such mixer feeder wagons arises when the fibrous fodder material is loaded into the mixing compartment through the upwardly facing open mouth in the form of a relatively large bale of the material, for example, a relatively large cylindrical bale of diameter of approximately 1 metre, of the type commonly referred to as a round bale, or a large parallelepiped bale of the type commonly referred to as a large square bale.
  • the bale of fodder material is relatively large, the mixing rotor can become overloaded with the sheer volume of fibrous fodder material being loaded into the mixing compartment through the open mouth.
  • Various attempts have been made to overcome this problem, including recommending that where the fodder material is in the form of a relatively large round or square bale, the bale should be initially opened and broken into smaller portions, and the smaller portions fed sequentially into the mixing compartment.
  • bale support bars are located in the open mouth extending transversely relative to the longitudinal axis of the mixing rotor.
  • the bale support bars extend partly across the open mouth, and partly support the bale of fibrous fodder material, with portions of the bale depending downwardly for engagement by the paddles of the mixing rotor as the mixing rotor rotates. This thus reduces the load on the mixing rotor.
  • a longitudinally extending blade is provided on a longitudinally extending side of the open mouth towards which the paddles of the mixing rotor advance as the mixing rotor rotates.
  • the paddles of the mixing rotor urge the depending portions of the fodder material against the blade to thereby sever the depending portions of the fodder material from the bale.
  • the support bars extend from the same longitudinally extending side of the open mouth as that on which the longitudinally extending blade is located.

  • minimising the power requirement of the mixer feeder apparatus the power requirement of a towing vehicle to tow and to operate the mixer feeder apparatus when the apparatus is configured as a towable mixer feeder wagon is similarly minimised, and thus, the mixer feeder wagon is suitable for towing and operating by a relatively wide range of towing vehicles.
  • the mixing compartment by sequentially delivering the depending portions of the fodder material into the mixing compartment, mixing of the ingredients is significantly enhanced, and the final mixed animal feed is homogenously mixed with the various ingredients and concentrates evenly dispersed throughout the animal feed. Furthermore, by sequentially delivering the fodder material into the mixing compartment sequentially in the form of the depending portions, the time required to homogenously mix the animal feed is significantly reduced over and above the time which would be taken to produce a homogenously mixed batch of animal feed if the fodder material of an entire bale of fodder material were to be simultaneously delivered into the mixing compartment.
  • the provision of the support elements in the mixing rotor enables the mixer feeder apparatus to handle a wide range of fodder and other ingredients of animal feed, and in particular, the provision of the support elements in the mixing rotor enables the mixer feeder apparatus to handle materials of both dry matter content and wetter type materials.
  • the provision of the support elements in the mixing rotor ensures that wetter materials are supported above the mixing rotor with depending portions thereof depending into the mixing rotor, which are thus sequentially severed from the bulk of the wetter material supported by the support elements.
  • wetter material which would, in general, require a considerably higher power requirement during both loading and mixing of the wetter material, the power requirement is maintained relatively low, and is similarly minimised by virtue of the fact that such wetter material is loaded into the mixing compartment in relatively small portions sequentially. This, thus, minimises the power requirement during loading, and also during mixing of the wetter materials.
  • the provision of the abutment element extending longitudinally along the side edge of the open mouth towards which the mixing rotor advances in conjunction with the support elements of the mixing rotor acts to retain and stabilise the bale of material in the open mouth above the mixing rotor.
  • the abutment element and the support elements on the mixing rotor co-operate to retain and stabilise the bale in the open mouth above the mixing rotor.
