An agricultural feed mixing and blending machine including a plurality of bins for different feed materials, variable speed metering augers in the bottoms of each bin to feed individual materials respectively to a confluence and mixing auger beneath the bins and operable to transfer the mixed material to a grinding unit, the confluence auger being operable when the metering augers are idle, to feed individual materials from an inlet hopper to an elevating auger and an upper transfer auger to deliver different materials respectively to the bins, the upper transfer auger also being reversible to deliver mixed material to the grinding unit, and a discharge auger being operable to receive mixed material and discharge it from the machine. The present invention primarily is concerned with the inclusion of a container for an additive, such as chemicals or medicinal drugs, to the discharge mechanism for the mixed material for blending the additive in a controlled manner. When feeding of the additive is stopped, the discharge mechanism purges the additive by feeding sufficient mixed feed material through the discharge mechanism to insure no residue of the additive therein.
A feed material mixing and blending machine comprising a plurality of bins respectively arranged to receive different feed materials, mixing mechanism to produce a mixture of said materials, metering means in each bin operable to feed said materials to said mixing mechanism to produce said mixture of said materials, conveying and discharge means operable to receive and convey said mixture for removal from said machine, in combination with separate power means respectively for said metering means and said conveying and discharge means, a container supported in said machine in communication with said discharge means and adapted to contain an additive material, additional metering means in said container operable to feed a controlled amount of said additive material to said discharge means and powered by the power means for said metering means for said bins, and control means for said power means respectively operable to stop at least the metering means for said additive material when feeding of the additive material is to stop.
A feed material mixing machine comprising at least two bins arranged to receive different feed materials, mixing mechanism to produce a mixture of said materials, means operable to feed said materials to said mixing mechanism to produce said mixture of said materials, conveying and discharge means operable to receive and convey said mixture for removal from said machine, in combination with power means for said conveying and discharge means, a container supported in said machine in communication with said discharge means and adapted to contain an additive material, metering means in said container operable to feed a controlled amount of said additive material to said discharge means and powered by the power means, control means for said power means operable to stop the metering means for said additive material when feeding of the additive material is to stop and said control means further being operable to continue the operation of said conveying and discharge means after said metering means has stopped to purge said means of all material therein.
