Maqolada bugungi kunda chorva mollari mahsuldorligini oshirishda muhim ahamiyatga ega boʻlgan dag‘al va shirali ozuqalar hamda ozuqabop sanoat chiqindilari bilan kombinatsiyalangan ozuqa aralashmasi tayyorlashning dolzarbligi ko‘rib chiqilgan. Ozuqa aralashmasini tayyorlash samaradorligini oshiruvchi muhim omillardan biri – bu uni oqimli usulda tayyorlash hamda energiya va resurstejamkor uzluksiz ishlovchi aralashtirgichdan foydalanishdir. Aralashtirgichning ish sifati, unumdorligi va energiya sarfiga toʻg‘ridan-toʻg‘ri ta’sir ko‘rsatadigan omillardan biri aralashtirgich kamerasi shaklini belgilovchi qopqoqni ishlab chiqish zaruratidir. Qopqoqning parametrlari nazariy va amaliy jihatdan aniqlangan bo‘lib, parametrlar va ishchi organ rejimining aralashtirgich ish unumdorligi va texnologik jarayonning bajarilishi uchun talab qilinadigan quvvatga ta’sirini ifodalovchi matematik formulalar ishlab chiqilgan. Tadqiqot natijalariga koʻra, aralashtirish kamerasida ozuqa aralashmasining bo‘lish vaqti 2,47 s, o‘qiy tezligi 0,81 m/s va aralashtirgichning ish unumdorligi 15,5 t/h ni tashkil etadi. Ozuqa aralashmasining hajmiy massasi 120÷600 kg/m3 oralig‘ida boʻlganda, aralashtirgichning nazariy ish unumdorligi 7÷24 t/h va texnologik jarayon bajarilishi uchun talab qilinadigan quvvat esa 0,45÷1,52 kVt bo‘lishi nazariy jihatdan asoslab berilgan. Olingan ma’lumotlar asosida uzluksiz ishlovchi aralashtirgichlardan sanoat namunalari ishlab chiqishda foydalanish tavsiya etilgan.

В статье рассмотрен актуальный на сегодняшний день вопрос приготовления комбикормовых смесей с грубыми и сочными кормами, а также с отходами кормопроизводства, имеющими важное значение для повышения продуктивности скота. Одним из важных факторов, повышающих эффективность приготовления кормовой смеси, является её приготовление поточным способом, а также использование энергоэффективного и ресурсосберегающего кормосмесителя непрерывного действия. Поэтому необходимо обоснование параметров крышки, соответствующей форме камеры кормосмесителя, так как это существенный элемент, непосредственно влияющий на качество работы, производительность и энергопотребление кормосмесителя. Данные параметры определены теоретически и практически, разработаны математические формулы, выражающие влияние параметров и режима работы рабочего органа на производительность и мощность кормосмесителя и необходимые для выполнения технологического процесса. Согласно результатам исследования, время нахождения питательной смеси в смесительной камере составляет 2,47 с, скорость движения оси шнека – 0,81 м/с, производительность кормосмесителя – 15,5 т/ч. Теоретически обосновано, что при объёмной массе питательной смеси в пределах 120÷600 кг/м3 теоретическая производительность смесителя составляет 7÷24 т/ч, а требуемая мощность для выполнения технологического процесса – 0,45÷1,52 кВт. На основе полученных данных было рекомендовано при разработке промышленных образцов использовать кормосмесители непрерывного действия.
The article reveals the current relevance of preparation of mixed fodder mixtures with coarse and succulent fodder, as well as with feed production wastes, which are good for raising the livestock productivity. One of the important factors increasing efficiency of preparation of a feed mixture, is its preparation by a flow method, and also use of energy-efficient and resource-saving continuous feed mixers. Therefore, it is considered important to justify parameters of a lid that will meet the shape of the feed mixer chamber, as it is an essential element immediately affecting the quality of work, productivity and energy consumption of the feed mixer. These parameters are determined theoretically and practically, mathematical formulas expressing the effect of parameters and mode of operation of the working body on the productivity and power of the feed mixer and required for implementation of the technological process have been developed. According to the research findings, the time of keeping the feed mixture in the mixing chamber is 2.47 sec., the speed of the auger axis is 0.81 m/s, the productivity of the feed mixer is 15.5 tons/h. Theoretical productivity of the mixer and the required power to perform the technological process have been justified to be 7÷24 t/h and 0,45÷1,52 kW, accordingly at the volumetric mass of the feed mixture within 120÷600 kg/m3 . As per retrieved data, the use of continuous feed mixers, is being recommended for developing industrial samples.
