  • ADVANCED INFORMATION TECHNOLOGIES IN PRECISION FARMING

    pg(s) 3-6

    Presented in this paper is the authors’ research of the different applications of the newest information technologies in agriculture.
    Provided in this article is information concerning the use and application of GPS receivers and GIS software, which are valuable for the up- to-date agriculture. These technologies and their applications provide numerous possibilities, as for example mapping of the nature’s resources, evaluation of the environmental impact, mapping of different soil types, etc.

    The different applications of the available hardware and software, which affects the efficacy and productivity of the agricultural activities, were analysed. Low-cost RTK-GPS receiver is represented. A technology for the data processing of the digital mapping information is provided as well.

  • APPLICATIONS OF A LASER SCANNER IN CROP PRODUCTION

    pg(s) 7-10

    New laser rangefinder scanners were developed specifically for drivers’ assistance and autonomous guiding in road vehicles.
    These sensor systems were tested in the past years regarding the potential for agricultural engineering purposes. In a first part of the paper a 2D laser rangefinder scanner was tested for detecting round bales on a harvested field from winter rye. In a second part the laser scanner was used for modelling crop stands and measuring crop biomass in winter wheat (R2=0.96) and maize (R2=0.95). In a third part, it was demonstrated that the height of the reflection point increased in a considerable manner depending on the detecting angle of the laser beam; resulting in an overestimation of crop height respectively of crop biomass.

  • RESEARCH RESULTS OF ADDITIONAL TRANSPORT DEVICE FOR THE ORDERLY PLACEMENT OF PRESSED BALES ON THE FIELD

    pg(s) 11-13

    An analysis the process of harvesting the field of large square bales of plant feed at different traffic pattern loading and transport units. We propose a constructive-technological scheme of additional transport unit for an orderly stacking of bales on the field surface in neat rows across the trajectory of the baler. The calculations of power requirement to drive the baler equipped with an additional transport unit. A technique for determining the area of compacted surface of the field propulsion units for different schemes of traffic during harvesting bales. Calculated the reduction in size of compacted surface of the field at harvest bales of flat series obtained from the use of additional transport unit. The results of energy research and technological performance of his work.

  • GO TO ENSURE EFFICIENCY AGRICULTURAL MACHINERY IN AGRICULTURE

    pg(s) 14-16

    Is it briefly described condition machine-tractor parka agricultural production at present. The formed crude structure of the system of the technical service in ACI Siberia. The offered mechanism of the shaping the system of the provision to capacity to work of the farm machinery on base of the motivation her parameter with the help of model forming: facilities, region, technical centre, specialized repair enterprise.

  • PERFECTION OF ASSEMBLY-TRANSPORT PROCESS ON CLEANING GRAIN IN SIBERIA

    pg(s) 17-18

    In the article the basic directions of rational construction of assembly-transport process (ATP) in conditions of Siberia are considered. The ways of perfection of process on cleaning of grain crops are proved. By means of modern technologies number of practical dependences on preparation and organizations of ATP on cleaning grain in view of applied schemes of transport service and a lining of optimum number of transport highways is certain. From set of technological schemes of transport service of harvesters and item primary grains cleaning in view of technological, industrial and zone factors were applied: direct transportations by single vehicles; transportations by turnaround trailers and trains; transportations with an overload of grain supersize trailer-conveyors all this allowed to perform transport operations irrespective of work of harvesters.

  • IMPROVEMENT OF SURFACE SOIL TREATMENT ROTARY IMPLEMENT

    pg(s) 19-20

    The article proposes a new rotary tillage implement for the surface soil treatment, which is based on an analysis of existing designs. This tool can be used as a separate unit, or as part of combination machines. It provides an effective weed combing process, dropping them on the field surface, the simultaneous crumbling, creating crumbly soil structure and the rolled seed boxes for rake crops.
