Definitions

  • the present invention relates to apparatus for mixing and dispensing material, and in particular fibrous type material, typically, animal feed which may include silage, hay or straw and other ingredients. Needless to say, the invention is not limited to mixing and dispensing apparatus for animal feed.

  • Typical mixer feeder wagons are disclosed in British Patent Specification No. GB-A-2, 139,911 and European Patent Specification No. EP-A-0,427,483.

  • the axial length of the mixing compartment of such mixer feeder wagons in general, would not exceed 4 metres.
  • mixing of the animal feed may be inadequate. This is particularly so where a substantial proportion of the fodder is fibrous material, typically, silage. It has been found that the mixing achieved in such mixer feeder wagons is less than adequate.
  • the mixing compartment of wagons of 20 cubic metre capacity in general, would be of axial length of approximately 5 metres long, and larger capacity wagons may be of axial length up to 8 metres and even longer, and it has been found that the dispersion of ingredients throughout the animal feed along the entire length of the wagon is not always acceptable.
  • the present invention is directed towards providing such apparatus for mixing and dispensing material.
  • apparatus for mixing and dispensing fibrous material comprising a container defining a hollow interior region which forms an elongated mixing compartment of partly circular transverse cross- section defining a longitudinally extending main central axis which is co-axial with the axis of generation of the partly circular portion of the mixing compartment, a mixing rotor being rotatable in the mixing compartment about a rotational axis coinciding with the main central axis, the mixing rotor comprising at least one elongated mixing paddle having a leading surface facing in the general direction of motion of the mixing paddle, wherein at least one of the mixing paddles is a first mixing paddle, and the leading surface of each first mixing paddle has a leading portion which is located intermediate a pair of longitudinally spaced apart trailing ends, the trailing ends being rearwardly disposed of the leading portion relative to the direction of motion of the mixing paddle, and the leading surface of each first mixing paddle extends from the leading portion to the respective trailing ends for urging material forwardly in the general

  • each mixing paddle defines an outer peripheral edge, the radius of which from the rotational axis of the mixing rotor is less than the internal radius of the partly circular portion of the mixing compartment.
  • the mixing rotor comprises a rotor shaft which is rotatably carried in the mixing compartment, each mixing paddle being radially spaced apart from the rotor shaft and being carried on corresponding carrier arms extending radially from the rotor shaft.
  • the partly circular portion of the mixing compartment is formed by an elongated longitudinally extending base of substantially semi-circular transverse cross-section.
  • a longitudinally extending side wall extending the length of the mixing compartment extends from the semi-circular base in a generally upward direction for defining one side of an open mouth to the mixing compartment.
  • the side wall is of arcuate transverse cross-section and of radius substantially similar to that of the base.
  • an elongated blade extends longitudinally parallel to the central axis and extends from the side wall into the open mouth, the blade terminating in an elongated longitudinally extending leading edge for co-operating with each mixing paddle for breaking up masses of fibrous material.
  • the blade extends substantially tangentially from the side wall, and extends in a direction towards the leading surface of each mixing paddle as the mixing paddle is rotating and approaching the blade.
  • first mixing paddles significantly improves the uniformity of distribution of the ingredients throughout the mixed materials. It has been found that the distribution of fibrous ingredients through the mixed materials is also relatively uniform. This is achieved by virtue of the fact that the leading surface of each first mixing paddle, as well as imparting a forward component of motion to the ingredients within the mixing compartment relative to the direction of motion of the mixing paddles also imparts a component of motion to the ingredients which is parallel to the main central axis of the mixing compartment. This latter component of motion which is parallel to the main central axis urges the ingredients towards one or other trailing end of the relevant first mixing paddle, depending on which part of the leading surface of the mixing paddle is imparting motion to the ingredients.
  • the ingredients are also moved in a general direction longitudinally along the mixing compartment parallel to the main central axis. This thus ensures a more even distribution of ingredients of the material being mixed over the entire length of the mixing compartment.
  • second mixing paddles has the added advantage that material which has been urged from the path of a first mixing paddle into the path of a second mixing paddle is mixed by the second mixing paddle in the location of the second mixing paddle with other materials in the mixing compartment.
  • each first mixing paddle extends from the leading portion of the leading surface to respective trailing ends of the leading surface avoids any danger of material being urged entirely towards one end of the mixing compartment.
  • the fibrous ingredients are supplied to the apparatus in bulk form, typically, in the form of a bale of fibrous material, such as, for example, a large bale of silage, hay or straw
  • the provision of the first mixing paddles facilitates in breaking up of the bale and separating the fibrous material from the bale for mixing with other ingredients.
  • This advantage is achieved by the co-operating action between the longitudinally extending blade adjacent the open mouth of the mixing compartment and the first and second mixing paddles, and in particular, the co-operating action between the longitudinal blade and the first mixing paddles.
  • the first mixing paddles co-operate with the longitudinal blade with a scissors type cutting action for cutting long fibrous ingredients into relatively short lengths. This scissors type action between the first mixing paddles and the longitudinal blade also minimises the power requirement required for cutting the fibrous material.
  • the apparatus When the apparatus is provided with a mixing compartment of capacity of 14/16 cubic metres and greater, significantly improved results are achieved over and above known apparatus of similar capacities.
  • the ingredients of the mixed material are relatively evenly and uniformly distributed throughout the mixed material, even where the ingredients include fibrous ingredients a relatively uniform distribution of the ingredients is also achieved, and the uniformity of distribution of the ingredients is significantly improved over mixes which can be obtained from apparatus known heretofore of similarly relatively large capacities.
  • Such improvements in the distribution of the ingredients in the mixed materials and in the reduced power requirements are also achieved in apparatus of smaller capacities constructed according to the invention.
  • Such smaller capacity apparatus may comprise a mixing compartment of capacity as low as 5 cubic metres, and even lower.
