JUSTIFICATION OF THE TRACTOR TRAILER FUNCTIONALITY FOR PREPARING SILAGE BY VACUUM METHOD

Abstract

In dairy farming, the main share of the diet is occupied by succulent feed, including silage, the share of which can be 65%. Due to the imperfection of silage preparation methods, significant losses of feed occur from 5 to 35%, depending on the method of preparation and storage. The creation of a feed base from succulent feed for small and medium-sized agricultural producers is achieved by expanding the functionality of the 2 SUTT - 4.5 tractor trailer by equipping it with the necessary equipment for performing silage operations. An algorithm for the process of vacuuming green mass is presented, consisting of 6 operations of a mobile unit. Based on the research results, depending on time, timing data was obtained, performed by the technical means of the unit. The longest operation in terms of harvesting time was vacuuming flexible containers - 14 minutes 40 seconds. Loading the crushed green mass is the fastest operation, carried out in 1 minute 32 seconds. This indicator depends on the yield of the field, as well as the productivity of the forage harvester. The conducted research made it possible to determine the additional functional purpose of the 2 SUTT - 4.5 tractor trailer and to develop a list of operations performed for the future preparation of silage in flexible containers by vacuuming on a mobile unit in the field conditions of an agricultural enterprise.
