Abstract:
An auger device of a vertical mixer for mixing animal feed, said auger device comprising:a core having a first and a second end; flighting secured to said core so that in operation of the mixer, when the auger device rotates, the animal feed is mixed; said flighting including; a first portion disposed helically around said core such that said first portion defines a first convolution and a second convolution disposed consecutively relative to said first convolution so that when said core rotates, the feed is urged by said first portion in a direction from said first towards said second end of said core; a second portion disposed helically around said core such that said second portion defines a third convolution and a fourth convolution disposed consecutively relative to said third convolution so that when said core rotates, the feed is urged by said second portion in said direction from said first towards said second end of said core; said third convolution being disposed between said first and second convolutions; a floor disposed adjacent to said first end of said core, said core being rotatable relative to said floor so that in use of the vertical mixer, said core rotates about a vertical axis extending normal to said said first portion has a first and a second termination, said first termination interacting with said floor such that when said core rotates relative to said floor, said first termination of said first portion sweeps the feed from said floor in said direction towards said second end of said core; said second portion has a first and a second extremity, said first extremity interacting with said floor such that when said core rotates relative to said floor, said first extremity of said second portion sweeps the feed from said floor in said direction towards said second end of said core; said first termination of said first portion and said first extremity of said second portion being spaced circumferentially about said vertical axis of said core; and said first termination of said first portion and said first extremity of said second portion are being spaced diametrically opposite to each other about said vertical axis of said core.
