RESULTS OF TESTS ON THE STALK AND GRAIN CRUSHER OF A SMALL FODDER SHOP

Abstract

It is known that in Kazakhstan, 70 ... 80 percent of peasant farms have no more than 100 head of cattle and 500 head of sheep. To fatten these farms and to prepare a complete ration with combined feed in dairy farms, a distributer-mixer with a box with a capacity of 3 ... 5 m3 is needed. Since the equipment of these distributer-mixer machines with stalk and grain crushers ensures that it chops fodder itself and loads them onto a hay rye and grain warehouse of a mobile fodder shop, in the process of preparing a full ration of a combined feed, the number of operations will be reduced by 1.67 times, and the operating costs of the unit will be reduced by 1.5 times. In addition, if the stalk fodder is crushed by zootechnical requirements, i.e. 30 to 50 mm, then the uniformity of the mixing process increases. Here you can mix with the addition of nutrient feed in the preparation of the combined feed, that is, the use of a mobile fodder shop in the household allows you to carry out the process of preparing a combined feed using new and inexpensive technologies, i.e. the use of a mobile fodder shop equipped with special crushers is a technological innovation. At present, the “Scientific Production Center of Agroengineering” on small farms is developing a mobile fodder shop for the preparation and distribution of compound feeds with a capacity of 5.0 m3, equipped with crushers for stalk and croup. In addition, in order to simplify the drive to the crusher and to make the design simple, the crusher of the stalk and grain are equipped with one bucket, that is, this is a technical novelty of the mobile fodder shop. Stalk and grain crushers of mobile fodder shops were made and tested. During the tests, the productivity of the stalk chopper is 2.5 ... 3.0 t/h, the power consumption is 6.2...7.0 kW, and the productivity of the grain crusher is 750 - 900 kg/h, and it was found that the power consumption in the performance range will be between 5.1 ... 7.2 kW. It was proved that the size of the crushed stalk and grain meets zootechnical requirements.
