20.500.12556/RUL-169050 Tehnične lastnosti in delovanje mešalno-krmilnih vozov za govedo Tehnical characteristic and operation of feed mixer wagons for cattle Mešalno-krmilni vozovi (MKV) so kmetijski stroji, ki se uporabljajo za pripravo in razdeljevanje krmne mešanice živalim, predvsem pri govedu. Te naprave so opremljene z mešalnimi sistemi, ki omogočajo homogeno mešanje različnih sestavin krmnega obroka in enakomerno razdeljevanje krme govedu, poleg tega pa povečajo storilnost ter zmanjšajo potrebo po ročnem delu. V okviru raziskave smo preučili delovanje in tehnične lastnosti MKV ter raziskali učinek krmljenja zmešane krmne mešanice (popolne ali delne), ki jo pripravimo s temi napravami. Podrobneje smo spoznali sestavne dele MKV in postopek priprave krmnih mešanic. Ključni dejavniki, ki jih morajo kmetije upoštevati pri izbiri MKV, so prostor oz. vhodna odprtina hleva, način shranjevanja silaže in sistem nakladanja ter praznjenja. V preizkusu smo preučili dve različni izvedbi MKV z različnimi načini polnjenja zalogovnika, da bi potrdili hipoteze, ki smo jih postavili ob pregledu objav. Ugotovili smo, da ni večjih razlik v kakovosti mešanja med horizontalno in vertikalno postavitvijo mešalnega polža. Vendar smo opazili, da MKV z vertikalno postavitvijo mešalnega polža slabše reže travno silažo v primerjavi s horizontalno postavitvijo. Opazili smo tudi večjo porabo goriva pri delu z MKV, ki ima horizontalno nameščene mešalne polže. Poleg tega je merjenje časa pokazalo, da je priprava krmnega obroka pri uporabi odvzemne žage počasnejša. Pri uporabi odvzemne freze in odvzemne žage smo dosegli gladko čelo odvzema silaže, medtem ko je uporaba nakladalnika in ščipalne žlice pokazala slabše rezultate. Feed-mixer wagons (FMW) are agricultural machines used for preparing and distributing feed mixtures to animals, primarily cattle. These machines are equipped with mixing systems that ensure consistent mixing of various feed components and even distribution of the feed to the cattle. Additionally, they increase productivity and reduce the need for manual labor. In this study, we examined the operation and technical characteristics of FMWs, as well as the effects of feeding total or partial mixed ration prepared by such machines. We familiarized ourselves with the components of FMWs and the process of preparing total or partial mixed rations. We also reviewed various types of FMWs, their advantages and disadvantages in loading and mixing different types of feed. The key factors that farms must consider when choosing a FMW are the space or barn entrance size, the method of silage storage, and the loading and unloading system. In the experiment, we tested two different FMW models with different methods of filling the mixing chamber, aiming to confirm hypotheses that were established through a review of publications. We found that there were no significant differences in the mixing quality between horizontally and vertically mounted mixing augers. However, we observed that the FMW with a vertically mounted auger performed worse in cutting grass silage compared to the model with a horizontally mounted auger. We also noticed higher fuel consumption by the tractor when working with FMWs with horizontally mounted mixing augers. Additionally, time measurements showed that preparing the feed ration was slower when using a cutting system whit scissor knives. When using a cutter drum and a scissor knives cutter, we achieved a smooth silage face, while the use of a loader and a shear bucket showed poorer results. govedoreja prehrana živali mešalno-krmilni vozovi tehnične lastnosti cattle breeding animal nutrition feeder-mixer wagons technical characteristics true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-05-09 07:15:17 2025-05-09 07:15:29 2025-05-10 04:10:30 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 257327 235311619 47851.pdf 47851.pdf 1 6ADA5740F077F9CCED64D831F883F406 e7e584ede6d57566d19931aee90a4e20f9484e63fa7249897d622bd45dd45203 70d3b1bb-2c93-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210185 Biotehniška fakulteta 0 0 0
