MACHINE FOR LOADING, MIXING AND DISPENSING OF FOOD Russian patent published in 1996 - IPC

FIELD: agricultural engineering; farming machines. SUBSTANCE: when machine reaches place of storage of one of food components, drive 11 is switched on. Food in required amount is loaded into bin 3 by means of loading device 4, then machine moves to other components in storage. When required amounts of food components are loaded, machine transports them to livestock house for dispensing. Food components are mixed by means of lower and upper screw conveyors 7 and 6, respectively, of food mixing and transportation mechanism when machine travels to livestock house. Intensification of mixing is provided owing to the fact that screw surfaces of conveyors 6 and 7 are made in form of oblique helicoid where particles of food move in axial, peripheral and radial directions. Settled food components are cut off by plate knives and are minced simultaneously. Arrangement of cutting edges of knives towards discharge port and acute angle to projection of screw axis improves conditions of cutting and cuts down power consumption. Making of screw surface of oblique helicoid in form of bands whose inner longitudinal edges are secured on screw shaft and outer edges are connected at acute angle relative to each other provides reliable operation of machine. After preparation of food mixture it is dispensed into livestock house troughs or feeding plot feed boxes by means of food dispensing mechanism 5. EFFECT: enlarged operating capabilities. 4 dwg
