INVESTIGATION OF CUTTING LENGTH OF STEMS IN CROPPING DEVICE

The article presents the results of theoretical and experimental researches to determine the cutting length of stems in a drum grinder and according to the obtained formula, in theoretical observations to determine the cutting length of stemmed fodder, it is determined that with an increase in the speed of rotation of the feed rollers or conveyors, the length of and the number of knives on the drum, the cutting length is reduced. In experimental studies carried out on a drum grinder at a constant rotation frequency of the grinding drum 1000 min-1 with an increase in the rotation frequency of the feed rollers from 100 min-1 to 200 min-1, it was determined that in the composition of the crushed mass fraction with a length of up to 5 mm decreases by 1.7-2.0 times, and fractions with a length of up to 2 cm increase by 1.5 times, and fractions longer than 2 cm are given up to 1.7 times and this shows that the results of theoretical research are in sufficient agreement with practice
