REGULARITY GROUNDS OF FEED MASS MOVEMENT IN A BLENDER WITH BLADES DECLINED RELATIVELY AN AXIS
In some areas of the Republic of Armenia a period of haying coincides with a rainy season of a considerable duration. As a result, we have a hay of a very high humidity, which can not be ricked up. In the best case, this mass without mixing with organic acids and a chopped straw is placed in a trench for ensilage. As a result of this process a low quality feed is obtained. To avoid such adverse phenomena with hay in adverse climatic conditions, it is proposed to grind and mix the crop with a high humidity with a chopped straw and preserve in concrete trenches. In the absence of concrete trenches for silos storage, a proposed technology of harvesting hay of a high humidity can be arranged in a temporary storage, built of straw bales. In the proposed technology the hardest, time-consuming and energy-intensive process is mixing of a mowed grass of a high humidity with straw. With this purpose a combined screw-blade mixer is designed which has successfully established itself in the process of a straw-manure mixture preparation during an aerobic expedited processing of a manure and a manure compost and also when mixed with a straw for a biological processing and obtaining of a biological humus. Moreover, a proposed screw-blade mixer can operate effectively in feed factories for making all kinds of feed mixtures. The article presents the laws of motion of a fodder mixer with blades deflected relative to an axis. It gives a calculation scheme of crop movement, a magnitude of forces acting in the direction of a screw axis, according to the angular velocity of its rotation.
