The substantiation and design of basic geometric and kinematic parameters of a broadcast tillage mill with horizontal axis of rotation are brought.
The necessity of providing the nominal output of machine-and-tractor unit by choosing rational operating modes of the tractor diesel engine has been theoretically justified. For the constant control of diesel engine charge during the work of machine-and-tractor unit, a device has been designed that is made of sensor, signal converter and load indicator.
A potato combine harvester adjustment procedure is suggested based on the operational process control. Due to the preset adjustment of working members, the tubers loss and damage are minimized.
A method was developed for designing a steering with adjustable kinematics of steering wheel turning. The results of its application for Belarus series 800 tractor are brought.
On the basis of the distribution analysis of quantity of farm tractors models presented in the market of german-language countries in 2009, it is suggested to divide all tractors having capacity from 30 up to 600 horsepower into six or five classes, according to their engine power.
A procedure realized in the computer program Microsoft Excel media with the use of queuing theory elements is described. It allows to take into account different variants of work organization during the fertilizers and ameliorants application.
The number of repair and maintenance personnel forming the mobile teams in service and dealer departments of livestock sector was analyzed in terms of cost savings. An example of calculation is given.
Article brings the results of experiment exploring the deformation of topsoil by caterpillar tractor, for the purpose of checking the adequacy of earlier made and published mathematical model of interaction of propeller with the supporting base, which has rheological properties.
The process of cutting soil with a point and a landward edge of a ploughshare combines the features of cutting with a blade and with a punch. High wastes of energy during this process are due to the pressed regime of cutting. The offered construction of plough (patent №2335107) allows to reduce the energy consumption.
In the article the general arrangement of performance evaluation of operation and competitive strength of the ploughing unit is considered, based on test results. Statistical characteristics of efficiency factors, regression models presenting the functioning of ploughing unit, and also the analysis of results are brought.
The concepts of a comprehensive program of machine and tractor fleet maintenance and repair are described, the relationship between reliability increase and programs improvement is shown. The mechanism of forming a comprehensive program and the sequence of its development are considered.
A new design of fodder shredder is suggested, with a reducer as transmission mechanism, containing a dual planetary reducer with four sun gears. This reducer provides the concordant operation of the technological line.
The article covers the problems of affordability, reduction of cost price of processing, overall dimensions, specific quantity of metal of fodder shredders and the problems of increasing their efficiency.
The failure-free performance of a brake system for mobile energetic transport vehicle is analysed. Some recommendations for use are made.
A universal technique of the multifactor cognitive system posterior tensor modeling is offered. The technique is based on the presentation of the multidimensional regression model of the multifactor cognitive system under examination in the form of the final valence covariant tensors vector sum, and it imposes minimum requirements to the experimental data volume necessary for the multifactor cognitive system identification, as well as to the multifactor cognitive system optimal condition evaluation according to this model. On this methodological basis and on the testing data basis, the environment and condition evaluation is made, it defines the precision plunger pair renewal process in a multicomponent chemical solution by sulfochromized coating having optimal physical-mechanical properties.
Some ways to improve sowing machines, taking into account actual requirements, are suggested. An area of development of fundamentally new seed distributors, better adapted for the installation on multifunctional machines, is highlighted. The results of studies of a new combined vibrating seed distributor at simultaneous sowing of wheat seeds and pelletized mineral fertilizers are given.
Basic approaches to the quality of agricultural machinery at the different stages of its creation are considered, from the substantiation and development of its сonstructional and technological diagrams to the processes of its use in agricultural industry.
The causes of the air-cooled diesel's cylinder deformation are analysed, leading to the increase in mechanical loss and decrease in reliability and service life.
