FODDER PREPARATION MACHINE Russian patent published in 2016 - IPC A23N17/00 

FIELD: technological processes; agriculture.

SUBSTANCE: invention relates to devices for mixing coarse, soft, watery and concentrated fodders. Fodder preparation machine comprises bed and drum installed on frame by means of elastic elements. Drum is made in form of container and is made of three rectangular strips bent alternately in opposite directions at an angle of 140° along notches with formation of equilateral triangles along length located alternating in opposite directions, strips are interconnected along lengthwise edges at an angle of 70° with formation of three broken curved screw surfaces along internal perimeter and three main direction broken screw grooves for fodder components displacement, as well as two broken curved screw surfaces and two opposite direction screw grooves for fodder components displacement from unloading to loading. Along container outer diameter of the three main direction broken screw lines are formed with pitch S and two opposite direction broken screw lines with pitch of 0.25S in screw lines break points, in which six equilateral triangles converging sides are located. Along container entire length cylindrical spring is mounted to move fodder components from loading to unloading, which has device to vary turns pitch by its stretching or compression.

EFFECT: use of the invention enables higher quality of finished product.
