THEORETICAL STUDIES OF THE WORKING PROCESS OF THE DISPENSER STEM FEED
Increasing the efficiency of livestock production is the most important task for workers in the agro-industrial complex. One of the main factors for obtaining high quality milk is a balanced year-round feeding of animals, which is provided by a system of machines and equipment for the production and preparation of feed for feeding to animals. Feed preparation for feeding is the most important technological operation on livestock farms and complexes, which is carried out daily, all year round. The main tasks of fodder production are to ensure balanced feeding of animals to obtain high weight gain and milk yield, rational use of fodder. The efficiency of feeding increases with the improvement of the nutritional value of the feed, the reduction of irretrievable losses, the increase in the level of mechanization and automation of the equipment used. In the article, on the basis of the research carried out, a theoretical generalization was carried out and a problem was solved that is of great national economic importance for the livestock industry to improve the efficiency of the functioning of machines and equipment for raising calves, which ensures the growth of animal productivity. Theoretical studies were carried out using the methods of theoretical mechanics, analytical geometry, mathematical modeling and analysis. The amount of feed dispensed can be adjusted by changing the conveyor lowering speed v<sub>op</sub> and the dispenser movement speed v<sub>m</sub>. The accuracy of calculating the productivity of the feed dispenser depends on the correct choice of the values of γ and ψ. As a result of the theoretical substantiation of the regime and design parameters of the combing conveyor, formulas were obtained for determining the productivity of the dispenser, the trajectory of the combing process, the filling factor of the inter-comb space, the volume of feed portions separated by the combs, the size and number of the combing tines. The specific resistance to the separation of feed by a rake will depend on the size of the penetration of the fingers into the feed mass.
