Cutting length the fodders of green stalks by drum chopper

Abstract

In Uzbekistan, special attention is paid to the development of livestock, poultry, and fish farming. In the ration of animals, green fodder obtained by cutting green stalks corn, alfalfa and other feed crops have a special place. For high-quality chopping of stalks with the required cutting length for each type of animal, a chopper has been developed with a simple design for chopping green feed. Testing of the chopper work, carried out at an engine speed of 2800 rpm, a cutting drum rotation speed of 950 rpm and in two rotations of the feed rollers 10 rpm and 20 rpm with an average length of alfalfa stalks 71.6 cm and an average length of corn stalks 216.4 cm, showed that at a feed roller rotation speed of 10 rpm the average cutting length of the stalks was 10.6 mm, and at a feed roller rotation speed of 20 rpm - 17.6 mm. It can be seen from the data that with a twice increase in the feed roll speed, the cutting length increases 1.66 times, which confirms the theoretical assumptions obtained.
