SELF-PROPELLED MIXER-DISTRIBUTOR SILOKING SELFLINE 4.0 PREMIUM 2215 TESTING

The purpose of research: a comprehensive assessment of self-propelled mixer-dispenser Siloking SelfLine 4.0 Premium 2215 during operation. Research methods: establishment of design features of the mixer-dispenser was performed by the survey method of the sample submitted for testing, quality indicators of the machine were evaluated by standardized methods: quality of technological process according to GSTU 46.008, operational-technological indicators according to DSTU 8424, energy indicators according to SOU 74.3-37 -04604309-824, economic indicators according to DSTU 4397, indicators of safety and ergonomics according to KD 46.16.02.03, SOU 74.3-37-133. Research result.: During the mixing of 5 types of feed, a high-quality homogeneous feed mixture was obtained, the moisture content of which was 59.5%, the bulk density was 405 kg / m3, and the average particle size was 17.4 mm. The uniformity of feed mixing was 94.3 %, and the uniformity of feed distribution was 95.5 %. The degree of grinding of stem fodder was 1.4 times (for hay). The test results show that the mixer-dispenser satisfactorily and efficiently performs the specified process. The feed monolith is preserved after passing the cutting drum, no looseness of the feed slice is detected. Returned losses at the bottom of the silo do not exceed 1 %. The productivity of the mixer-dispenser for the technological process of loading, transportation, mixing and distribution of feed on a dairy farm with a population of 1600 heads is 10.6 t / h, the average productivity of feed loading is 28.6 t / h. (including silage -41 t / h; haylage 43.4 t / h), feed distribution capacity −116 t / h. Specific fuel consumption is 1.2 liters per ton of loaded, crushed, mixed and distributed feed. Labor costs for the implementation of the technological process is 0.09 man-hours / t, direct operating costs -91 UAH / t. Conclusions. Self-propelled mixer-dispenser Siloking SelfLine 4.0 Premium 2215 is a multifunctional machine that allows, with the involvement of only one operator, to ensure self-loading of components, preparation and distribution of quality feed to animals at a given diet. During self-loading the error of dosing of components by the mixer-distributor does not exceed 0,5% that allows to prepare a forage mix close to settlement. The self-loading milling working mechanism of the mixer-distributor provides an equal cut of a monolith of silage and haylage that allows to keep quality of consolidation and prevents losses of nutritiousness and power value of a forage. Self-propelled mixer-distributor is characterized by 1.5 - 2.1 times higher than trailed mixer-distributors productivity of the process as a whole, has a high enough productivity of self-loading components and distribution of feed, minimizes specific labor costs and fuel consumption per 1 tons of cooked and distributed feed.
