Development of new design-technological scheme of harvesting haulm of sugar beet with the use of a tillage-row-crop tractor

Abstract

The purpose. To develop and test under production conditions the new combined assembly unit for harvesting haulm of sugar beet with the use of integral tillage-row-crop tractor. Methods. Method of use of machines in plant growing, experimental researches and field tests of farm machines, and also evaluation procedure of quality factors of their operation. Results. New design-technological scheme of harvesting haulm of sugar beet is developed and justified with application of integral tillage-row-crop wheeled tractor of tractive class 3. At use of wheeled tractor of such type the necessary condition is the availability of fast-head and rear hinged gears and shaft of output couplings, and also adjustment of its wheels for the necessary width of row widths of sowings of sugar beet. The production process of harvesting haulm of sugar beet is carried out in 2 stages: top-gathering machine frontally positioned on a tractor realizes the basic solid shearing of all array of haulm and loads it into transport equipment. Conclusions. The designed and tested combined assembly unit for harvesting haulm of sugar beet stably executes production process and has quite high quality factors of harvesting. However at operation of that top-gathering machine the percentage of crushing leaves of haulm (60 – 65%) is too high occurs at its solid shearing and loading.
