Calculation and theoretical substantiation of the indicators of diesel D-243 (4H 11/12,5) when working on mixed mustard-mineral fuel

The use of mustard oil as a biological component to mineral fuel and the preparation of mixed mustard-mineral fuel in the diesel power supply system directly during the operation of the tractor unit, with a slight decrease in diesel power, improves the environmental performance of the tractor, provides fuel economy of petroleum (mineral) origin.

The influence of rectangular shape holes on energy intensity of grinding grain

Grain before feeding to animals exposed to grinding with the purpose of increasing its digestibility. As a result of this increases the area of interaction of the feed with the gastric juice and decreases the conversion coefficient. Surface theory formulated by German scientist Rittinger, suggests that the work of AR required for the grinding process is directly proportional to newly formed surface. The purpose of this paper is a theoretical evaluation of the intensity of grinding with the use of sieves with rectangular and circular shape holes. When getting groats with the same grinding module by the use of sieves with holes of rectangular shape, one should expect the decrease of specific energy intensity. By reducing the content of dust-like fractions and reduce the total surface feed should be expected to reduce the energy intensity of pneumo transportation.

Use of fallow lands to create new farm (peasant) farms

The organizational mechanism of the implementation of the Subprogram "Support of small forms of management" is proposed due to the development of fallow lands and the creation of cooperatives on these lands from newly created farms (peasant) farms.

Technology and organization of storage of combine harvesters

During long-term storage, climatic and atmospheric factors affect the agricultural machine, which cause changes in the physical and chemical properties of structural materials, technical fluids, lubricants. Therefore, the development of technical and organizational measures related to improving the storage efficiency of combine harvesters is an urgent scientific task that the leading scientific institutes of the country are engaged in.

Differential integral functions

The definition of differential integral functions based on Laplace transformations and the definition of differential integrals, as well as their representation on graphs and in the text, is given. An example of approximation of a function using differential integral functions is given.

Study of structures of tillage working bodies with overhead chisel

Agriculture is the most important branch of the national economy, providing the population of our country with food and obtaining raw materials for a number of industries. The role of agriculture in the economy of Russia and its regions shows the structure and level of development of the state. It is impossible to get a good harvest without proper cultivation of the land. Cultivation of any crops begins with basic tillage, which is one of the most time-consuming operations. For this purpose, mounted and semi-mounted ploughshares are used. One of the effective ways to reduce the energy intensity of the main tillage process is chisel-shaped ploughshares with a protruding toe (chisel), which is located below the blade by 20 … 25 mm. Due to this, the sinking capacity of the hull and its resource are improved. To achieve this goal, such methods are used as the influx of metal in the field-cut zone, which increases its thickness, the surfacing of the nose part, which increases wear resistance and, accordingly, reduces wear of the sock in thickness, welding to the sock with a plate made of a more high-strength material [1].

Software for processing multispectral data and field digitization

This article considers the programs used in agriculture for photogrammetric processing of multispectral data and field digitization. With the help of these programs, it is possible to obtain the necessary information for assessing the state of plant development.

Brief analysis of the provision of agricultural machinery to agricultural enterprises of the Republic of Belarus

Long-term foreign and domestic experience in agricultural production proves that the intensification of agricultural production, an increase in its efficiency and volumes, an increase in the competitiveness of agricultural products, is impossible without constant modernization of the production and technical base and the introduction of the most modern achievements of scientific and technological progress. Only a comprehensive and systematic technical and technological reequipment of agricultural production, saturation of it with high-tech, high-performance complexes, machines, equipment can provide a significant increase in labor productivity, minimize the cost of all types of material resources with a steady trend of constantly decreasing labor resources in agricultural production. The analysis of indicators of provision with the main types of machines of domestic agricultural enterprises in comparison with different countries of the world is carried out. The article presents the results of the analysis of the most important segments of the agricultural tractor and combine park of the Republic of Belarus.
